Description

The present invention relates to an electrical panel, such as an electrical door, of a disaster prevention equipment storage device such as a fire hydrant device equipped with electrical equipment such as a transmitter and a response indicator light, a disaster prevention equipment storage device having such an electrical panel, and disaster prevention equipment equipped with such a disaster prevention equipment storage device.

Conventionally, fire hydrant devices, a type of disaster prevention equipment storage device installed in tunnels on expressways and expressways, have a hydrant storage section in a housing with a hydrant door that can be opened and closed, which stores hoses with nozzles attached to the ends and valves. Also, a fire extinguisher storage section with a fire extinguisher door that can be opened and closed stores, for example, two fire extinguishers. Furthermore, an electrical door, which is an electrical panel with a door structure, is provided between the hydrant door and the fire extinguisher door. The electrical door is equipped with a red indicator light, a transmitter (fire alarm device), and a response lamp (response indicator light), and a telephone jack is also provided on the back side of the electrical door.

The red indicator light stays on at all times, allowing the location of the fire hydrant device to be identified from a distance. When a fire occurs and the transmitter is pressed, turning on the push button switch, a transmission signal is sent. This signal is received by the disaster prevention receiving panel installed in the electrical room, etc., which issues a fire alarm, and a response signal is sent from the disaster prevention receiving panel. When the fire hydrant device receives this signal, its response lamp lights up and its red indicator light flashes.

In conventional fire hydrant systems, the position of the electrical equipment is not changed, and the wiring cables connecting the electrical equipment to the terminal box installed on the back of the fire extinguisher storage section adjacent to the electrical door are of approximately constant length, so they are bundled together using cable ties or similar devices and laid inside the housing.

JP 2016-055073 A Japanese Patent Application Laid-Open No. 2018-139704

In recent years, the installation height of fire hydrant devices from the roadway surface has changed depending on the design and characteristics of the tunnel's structure, such as its shape. In such cases, if the position of the transmitter installed on the hydrant device is not changed, and the transmitter height does not fall within the range specified by the Fire Service Act, it will be necessary to review the shape, detailed design, and manufacture of the fire hydrant device, including a new electrical door, each time.

In such cases, the wiring route and fixing method of the associated cables must also be changed to accommodate the new electrically equipped door, which can lead to inefficient and complicated problems. Furthermore, while the height of the transmitter meets the Fire Service Act regulations, it is positioned too high for the operator standing on the road surface of the guard's passage, making it difficult for some people to operate.

Furthermore, when a tunnel's grade is upgraded or downgraded, observer passages may be added, and the height of the road surface where the operator stands may change. In such cases, it is desirable that the location of transmitters be within the range specified by the Fire Service Act, without having to replace the fire hydrant equipment, including the electrically equipped doors, with new ones.

To solve this problem, the applicant has proposed an electrical door that allows the placement of electrical equipment such as transmitters and response lights to be easily and simply changed depending on the installation status of the fire hydrant or other disaster prevention equipment storage device, the operator's standing position, etc. (Patent Application No. 2021-049525).

In electrical doors that allow the placement of electrical equipment to be changed, the length of the wiring cable connecting the terminal block to the electrical equipment changes depending on the placement of the electrical equipment. Therefore, wiring cables with a sufficient length are prepared, taking into account the placement of the electrical equipment, which will be the longest, and are then bundled using cable ties or the like and laid inside the housing.

However, if the location of electrical equipment is changed, it is necessary to cut the cable ties, adjust the length of the wiring cables, then re-bind the cables with cable ties and adjust the wiring route within the enclosure.

As a result, at manufacturing sites such as factories, it is not possible to decide on a single set of work procedures for laying out wiring cables; instead, different work procedures must be decided and selected depending on the location of the electrical equipment, making the wiring work complicated and time-consuming.

In addition, when working inside tunnels, it is expected that the work environment will make it even more difficult to lay wiring cables inside the enclosures when changing the location of electrical equipment. Furthermore, since work inside tunnels involves road closures and lane restrictions, the length of time required to change the location of electrical equipment will become an issue.

The present invention aims to provide an electrical panel that simplifies and facilitates the wiring of electrical cables when changing the location of electrical equipment, thereby improving workability; a disaster prevention equipment storage device that includes the electrical panel; and disaster prevention equipment that includes the disaster prevention equipment storage device.

(Disaster prevention equipment storage device, disaster prevention equipment)
The present invention is characterized by a disaster prevention equipment storage device having the above-mentioned electrical panel, or disaster prevention equipment equipped with the disaster prevention equipment storage device.

(Effect of electrical panel)
According to the present invention, an electrical panel of a disaster prevention equipment storage device on which a plurality of electrical devices are installed comprises: a panel main body on which the electrical devices are arranged so that their positions can be changed; wiring that connects the electrical devices to terminal blocks arranged in predetermined positions on the disaster prevention equipment storage device; and a wiring storage section arranged on the back side of the panel main body, in which the intermediate portions of the wiring are slackened and stored so that they can be easily inserted and removed. Since the length of the wiring from the terminal blocks to the electrical devices can be changed in response to changes in the position of the electrical devices, for example, if the installation height of the electrical devices from the road surface on which an operator stands changes and the position of the electrical devices is changed, the intermediate portions of the wiring are stored in a slack state in the wiring storage section, providing redundancy in the wiring length. Therefore, if the electrical devices are relocated to a position away from the terminal blocks, the shortfall in the wiring can be pulled out of the wiring storage section to increase the wiring length, and on the other hand, if the electrical devices are relocated to a position closer to the terminal blocks, the excess wiring can be pushed into the wiring storage section to shorten the wiring length. By moving the wiring in and out of the wiring storage section, the wiring length can be simply and easily changed in response to changes in the position of the electrical devices.

In addition, the wiring connecting the wiring storage section and the terminal block is not affected by changes to the placement of electrical equipment. Therefore, even if the wiring is tied together with cable ties or the like and laid inside the housing, there is no need to cut the cable ties to change the wiring length or change the wiring path inside the housing, allowing for efficient work.

(Effects of the first wiring storage section)
The first wiring storage section comprises a box-shaped storage body having a height corresponding to a predetermined range in the height direction of the panel body, a first opening formed with a predetermined width in a predetermined range in the height direction on the surface of the storage body facing the panel body, an elastic closing member that closes the first opening and has a notch formed in a predetermined range in the height direction for inserting wiring from the electrical equipment, and a second opening formed on the other surface of the storage body other than the surface on which the first opening is formed, for inserting wiring from the terminal block. Therefore, since the wiring is stored in a slackened state in the wiring storage section, the wiring length can be simply and easily changed in response to changes in the placement position of the electrical equipment by inserting or removing the wiring in or from the wiring storage section. In addition, by forming a notch in the elastic closing member that closes the first opening formed in the box-shaped storage body and inserting the wiring to the electrical equipment through the notch, the inserted wiring is held by being clamped by the elastic force of the notch, making it easy to insert or remove wiring from the electrical equipment and also enabling the wiring length changed by inserting or removing the wiring in or from the wiring storage section to be reliably maintained.

(Effects of the second wiring storage section)
The second wiring storage section includes a box-shaped storage body having a height corresponding to a predetermined range in the height direction of the panel body; a first opening formed with a predetermined width in a predetermined range in the height direction on a surface of the storage body facing the panel body in the storage body; a plurality of wiring fixing members provided corresponding to each electrical device, the wiring fixing members being elastic plate members having cutouts formed therein for inserting wiring from the electrical device and arranged to be movable in the height direction along the first opening; and a second opening formed on the other surface of the storage body except for the surface on which the first opening is formed, for inserting wiring from the terminal block. Therefore, the wiring fixing members provided with elastic plate members having cutouts for inserting wiring for each electrical device are arranged to be movable along the first opening formed in the box-shaped storage body, and the positions of the wiring fixing members can be changed in response to changes in the positions of the electrical devices. Therefore, changes in the wiring length from the electrical device that pass through the elastic cutouts of the wiring fixing members can be absorbed by changes in the slack of the wiring within the storage body without changing the length of the wiring from the electrical device that passes through the elastic cutouts of the wiring fixing members, and there is no need to change the wiring layout between the terminal block and the electrical device via the wiring storage section.

(Effects of the third wiring storage section)
In addition, the third wiring storage section comprises a cylindrical body made of a hard elastic body having a height corresponding to a predetermined range in the height direction of the panel body and having a first opening having a predetermined width formed in a predetermined range in the height direction on the outer peripheral surface facing the panel body, a closing member made of a soft elastic body that closes the first opening and has a notch formed in a predetermined range in the height direction for inserting wiring from the electrical equipment, and a second opening formed on the upper end surface of the cylindrical body for inserting wiring from the terminal block.Therefore, in addition to the effect of being able to simply and easily change the wiring length in response to changes in the placement position of the electrical equipment, as with the first wiring storage section, the wiring storage section as a whole is cylindrical, making it possible to reduce the placement space on the back side of the panel.

(Effects of electrical equipment)
The electrical equipment also includes a red indicator light to indicate the installation location of the disaster prevention equipment storage device, a transmitter to send a fire report to the receiver, a response indicator light to display a response from the receiver to the fire report, and a telephone jack located on the back of the panel body for connecting an emergency phone; at least the transmitter, response indicator light, and telephone jack are arranged on the panel body so that their positions can be changed, making it possible to simply and easily change the wiring length in response to a change in the position of at least one of the red indicator light, transmitter, response indicator light, or telephone jack by moving the wiring in and out of the wiring storage section.

Embodiments of an electrical panel according to the present invention are described in detail below with reference to the drawings. Note that the present invention is not limited to the following embodiments.

[Basic Concept of the Embodiment]
First, the basic concept of the embodiment will be described. The embodiment generally relates to an electrical panel of a disaster prevention equipment storage device in which predetermined electrical equipment is arranged, and more specifically, to an electrical door of a fire hydrant device installed in a tunnel, which has a door structure and is equipped with a red indicator light, a transmitter, a telephone jack, and a response indicator light as predetermined electrical equipment.

Here, "electrical panel" refers to a panel installed in a disaster prevention equipment storage device on which electrical equipment for disaster prevention operations and displays is arranged and attached, and is a concept that includes electrical doors and other devices installed in the disaster prevention equipment storage device that have a door structure that can be opened and closed. In the case of a fire hydrant device where the disaster prevention equipment storage device is installed in a tunnel, "electrical door" is a concept that includes a door installed in the fire hydrant device and equipped with specified electrical equipment such as a red indicator light, transmitter, telephone jack, and answering indicator light.

Here, a "red indicator light" is an indicator light that indicates the location of a fire hydrant device. A "transmitter" is a device for reporting a fire, and is a concept that includes operating switches and the like for operating fire reports. A "response indicator light" is an indicator light that responds to a fire report from the transmitter with a signal from the receiver, and is a concept that includes a response lamp. A "telephone jack" is a device located on the back of an electrical door, and is used to connect an emergency telephone for making calls.

The electrical panel of this embodiment is composed of a panel main body, wiring, and a wiring storage section. Here, the "panel main body" refers to the electrical equipment mounted in a repositionable manner. For example, a red indicator light is mounted at the top of the panel surface of the panel main body, and its position is fixed and cannot be changed. In contrast, the position of the transmitter can be changed depending on the installation status of the disaster prevention equipment storage device, such as a fire hydrant, and the standing position of the operator. Furthermore, the positions of the answering indicator light and telephone jack can be changed in accordance with changes in the position of the transmitter.

"Wiring" refers to the electric wires that connect the electrical equipment installed in the panel body to the terminal blocks housed in terminal boxes located in designated positions in disaster prevention equipment storage devices such as fire hydrants. Here, "electric wire" legally refers to an electric conductor used to transmit high-current electricity, an electric conductor coated with an insulator, or an electric conductor coated with an insulator and protected by a protective coating, and does not include those used to transmit low-current electricity such as in communication circuits. In this embodiment, "electric wire" refers to an "electric conductor coated with an insulator and protected by a protective coating," and is generally a concept that includes "insulated electric wires," "cables," or "wiring cables" used in power circuits of 100V or more, and is an electric wire that is strong and durable.

The "wiring storage section" is located on the back side of the panel body and stores the wiring in a loosened manner, allowing it to be freely inserted and removed. By inserting and removing the wiring, the length of the wiring can be changed in response to changes in the placement position of the electrical equipment.

The wiring storage section of this embodiment comes in three different configurations: a first wiring storage section, a second wiring storage section, and a third wiring storage section.

(First wiring storage section)
The "first wiring storage section" is composed of a storage body, a first opening, an elastic closing member, and a second opening. Here, the "storage body" is a box-shaped storage body having a height corresponding to a predetermined range in the height direction of the panel body on which the electrical equipment is arranged, and the "first opening" is an opening formed with a predetermined width within a predetermined range in the height direction of the surface of the storage body facing the panel body.

Here, an "elastic closing member" is an elastic member that closes the first opening of the storage body and has a notch formed within a predetermined range in the height direction for inserting wiring from the electrical equipment. The term "elastic member" also encompasses the term "elastomer member." "Elastomer" is a general term for elastic polymeric materials, and includes, for example, rubber (natural rubber, synthetic rubber) and resin-based elastomers (urethane rubber, silicone rubber, fluororubber, etc.). Therefore, the term "elastic closing member" encompasses the term "closing elastomer member."

Here, the "second opening" refers to an opening formed on a surface of the storage body other than the surface on which the first opening is formed, such as the top surface, for inserting wiring from the terminal block.

(Second wiring storage section)
The "second wiring storage section" is composed of a storage body, a first opening, a wiring fixing member, and a second opening. Here, the "storage body,""firstopening," and "second opening" are the same as those of the first wiring storage section. The "wiring fixing member" is an elastic plate member provided for each electrical device, with a notch formed therein for inserting the wiring from the electrical device, and arranged so as to be movable in the height direction along the first opening. The term "elastic plate member" is a concept that includes an "elastomeric plate member."

(Third wiring storage section)
The "third wiring storage section" is composed of a tubular body, a first opening, a closing member, and a second opening. Here, the "tubular body" refers to a cylindrical member, for example, made of a hard elastic body having a height corresponding to a predetermined range in the height direction of the panel main body on which the electrical equipment is arranged, and having a first opening having a predetermined width formed within a predetermined range in the height direction of the outer peripheral surface facing the panel main body. Note that the "hard elastic body" is a concept that includes "hard elastomer," and is a body that is strong enough to maintain its tubular shape with its own rigidity.

Here, the "first opening" refers to an opening of a predetermined width formed within a predetermined range in the height direction on the surface of the storage body facing the panel body, and the "closing member" refers to a member made of a soft elastic material that closes the first opening of the cylindrical body and has a notch formed within a predetermined range in the height direction for inserting wiring from electrical equipment. The term "soft elastic material" encompasses the concepts of "soft elastomer" and "soft rubber." The "second opening" refers to an opening formed on another surface of the storage body other than the surface on which the first opening is formed, such as the upper end surface of the cylindrical body, for inserting wiring from the terminal block.

Specific embodiments are described below. In the specific embodiments described below, the "disaster prevention equipment storage device" is a "fire hydrant device installed in a tunnel," the "electrical panel" is an "electrical door," and the "electrical equipment" installed on the electrical door of the fire hydrant device includes a "red indicator light," a "transmitter," and an "answer lamp" that functions as a response indicator lamp. Furthermore, a "telephone jack" is provided on the rear side of the door (rear side of the panel), and the positions of the transmitter, answer lamp, and telephone jack are adjustable. The "wiring storage section" is described separately as a "first wiring storage section," a "second wiring storage section," and a "third wiring storage section." Furthermore, the "panel body" of the electrical panel corresponds to the "door body" of the electrical door, and the "panel front surface" and "panel rear surface" of the panel body correspond to the "door front surface" and "door rear surface" of the door body.

[a. Fire hydrant equipment]
A fire hydrant device for a tunnel, which is an example of a disaster prevention equipment storage device of this embodiment, will be described in more detail below. In this description, reference will be made to Fig. 1, which is an explanatory diagram showing a fire hydrant device for a tunnel. Fig. 1(A) is an explanatory diagram showing the installed state of the fire hydrant device as viewed from a cross section of the tunnel, and Fig. 1(B) is an explanatory diagram showing the installed state of the fire hydrant device inside the tunnel as viewed from a longitudinal section of the tunnel.

In the description of Figure 1, the X-Y-Z directions are mutually orthogonal directions. Specifically, when looking at the front of the fire hydrant device 10, the X direction is the left-right direction, the Y direction is the up-down direction, and the Z direction is the front-to-back direction. Furthermore, the +X side of the X direction is the right side, the -X side is the left side, the +Y side of the Y direction is the top side, the -Y side is the bottom side, and the +Z side of the Z direction is the front side, and the -Z side is the rear side. In this respect, the X-Y-Z directions are the same in Figures 2 to 24, which illustrate embodiments of the present invention.

As shown in FIG. 1, the fire hydrant device 10 has a structure divided into a housing 10a on the hydrant storage side and a housing 10b on the fire extinguisher storage side, and a stand 11 is attached to the underside of the fire hydrant device 10, and decorative frames 13a, 13b are attached to the front of the housings 10a, 10b.

(a1. Overview of fire hydrant equipment)
The door opening of the decorative frame 13a on the fire hydrant storage section side is divided into upper and lower sections, and a forward-leaning fire hydrant door 14 that opens downward on hinges 15a is installed at the lower part of the door opening, and a maintenance door 17 that opens upward on hinges 15b is installed at the upper part of the door opening, and inside the fire hydrant storage section, fire hoses with nozzles and valves including fire hydrant valves are stored.

A fire extinguisher door 18 that swings sideways to the left on hinges 15d is provided on the left side of the door opening in the decorative frame 13b on the fire extinguisher storage section side, and the fire extinguisher storage section inside can store, for example, two fire extinguishers. A viewing window 22 is also provided below the fire extinguisher door 18, allowing the user to check from the outside whether or not the fire extinguisher is stored.

(a2. Electric door)
An electrical door 12, which is an electrical panel having a door structure that opens sideways to the right on a hinge 15c, is provided on the right side of the door opening of the decorative frame 13b. The electrical door 12 is provided with electrical equipment such as a red indicator light 20, a transmitter 24, an SOS display board 27, and a response lamp 26, and a telephone jack is provided inside the housing of the electrical door 12.

The red indicator light 20 is always lit, allowing the location of the fire hydrant device 10 to be seen from a distance. The red indicator light 20 is also located at the top of the front of the electrically equipped door 12, and its position will never be changed.

In this embodiment, the transmitter 24, SOS display board 27, and response lamp 26 are located on the upper side of the front door of the electrical door 12. The transmitter 24, SOS display board 27, and response lamp 26 may be relocated to the lower side of the front door of the electrical door 12. To allow for this relocation, a transmitter placement opening 24a and a response lamp placement opening 26a are formed on the lower side of the front door of the electrical door 12, and are closed by closing plates 240 and 260, respectively. Four screw holes are formed on the door surface between the transmitter placement opening 24a and the response lamp placement opening 26a for placement of the SOS display board 27, but since these holes are unused, they are closed by screws 270.

As shown in Figure 2, the transmitter 24, telephone jack 25, and answer lamp 26 are attached to a base member 46, for example. Note that Figure 2(A) shows the front view, and Figure 2(B) shows the side view.

As a result, by installing the base member 46 on the upper back side of the electrical door 12, the transmitter 24, telephone jack 25, and answer lamp 26 are positioned on the upper front side of the electrical door 12, as shown in Figure 1. Furthermore, by relocating the base member 46 to the lower back side of the electrical door 12, the positions of the transmitter 24, telephone jack 25, and answer lamp 26 can be changed to the lower front side of the electrical door 12. The transmitter 24, telephone jack 25, and answer lamp 26 may also be individually positioned and installed without being attached to the base member 46.

When a fire breaks out and the transmitter 24 is operated to turn on the push button switch, a transmission signal is sent. A fire alarm is issued from the disaster prevention receiving panel installed in the electrical room, etc., which receives this signal and sends a response signal. When the fire hydrant device 10 receives this signal, the red indicator light 20 flashes and the response lamp 26 lights up.

(a3. Internal structure of fire hydrant device)
The internal structure of the fire hydrant device will be described in more detail. As shown in Figures 3 to 5, the interior of the housing 10a, which serves as the fire hydrant storage section 16, is divided into a valve storage section 16a and a hose storage section 16b. Here, Figure 3 shows the internal structure from the front with the hydrant door and maintenance door open and the fire extinguisher door removed, Figure 4 is a cross section taken along the line a-a in Figure 3, and Figure 5 shows a side view of Figure 4 with a partial cutaway.

A water supply piping 31 drawn in from outside is connected to a water supply hydrant 30 in the valve storage section 16a. The water supply piping 31 branches downward and is connected to a fire hose 38 via a hydrant valve 32 and an automatic pressure regulating valve 34. The hydrant valve 32 is opened and closed by a hydrant valve opening/closing lever 36, which is remotely opened and closed by a known wire link mechanism that opens and closes the hydrant valve opening/closing lever 36. When the hydrant valve opening/closing lever 36 is opened or closed, a pump start-up interlock switch 44 mounted on the operation box is turned on and off. A pump start-up switch 42 for use by the fire brigade is also provided to the upper right of the hydrant 30.

A hose storage frame 35 is provided in the hose storage section 16b, and a fire hose 38 is pulled in from below and stored in a clockwise or counterclockwise inward coil. A nozzle 40 is attached to the end of the fire hose 38 pulled out through a hose guide 37, and the nozzle 40 is detachably held in a nozzle holder 41.

The interior of the housing 10b (on the fire extinguisher door 18 side) is the fire extinguisher storage section 19, which, as shown in Figure 4, stores two fire extinguishers 29. Terminal boxes 28a and 28b are installed on the rear surface of the fire extinguisher storage section 19.

A first wiring storage section 50 is disposed by a support pole 52 on the rear surface of the electrical door 12 disposed adjacent to the fire extinguisher door 18 of the fire extinguisher storage section 19. The first wiring storage section 50 accommodates wiring cables connecting the terminal block of the terminal box 28a to the red indicator light 20 of the electrical door 20 , as well as wiring cables connecting the terminal block of the terminal box 28b to the transmitter 24, telephone jack 25, and answer lamp 26 of the electrical door 20. Each wiring cable is stored in a slackened state as it passes through the first wiring storage section 50. When the wiring length changes due to a change in the positions of the transmitter 24, telephone jack 25, and answer lamp 26, the change in wiring length can be accommodated by moving the wiring cable in and out of the first wiring storage section 50.

As shown in Figures 4 and 5, a cable rack 48 is installed in the fire hydrant storage section 16 inside the housing 10a. The cable rack 48 is arranged in the left-right direction from approximately the center of the valve storage section 16a, through the hose storage section 16b, and just before the partition wall 21 separating it from the fire extinguisher storage section 19, and a wire passage opening 47 is opened in the partition wall 21 opposite the left end of the cable rack 48.

The cables pulled into the valve storage section 16a from the outside and the cables from the pump start switch 42 and pump start interlock switch 44 are inserted through the entrance at the right end of the cable rack 48, passed through the cable rack 48, pulled out toward the fire extinguisher storage section 19, and connected to the terminal box 28a or terminal box 28b.

(a4. Fire hydrant device cable wiring system)
The cable wiring system of the electrical equipment arranged in the housing 10b of the fire hydrant device 10 will be described in more detail. As shown in Fig. 6, the electrical door 12 of the housing 10b is provided with the following electrical equipment: a red indicator light 20, a transmitter 24, a response lamp 26, and a telephone jack 25. The red indicator light 20 is connected to a corresponding terminal of the terminal block 280a of the terminal box 28a, and the transmitter 24, the response lamp 26, and the telephone jack 25 are connected to corresponding terminals of the terminal block 280b of the terminal box 28b.

In addition, the pump start switch 42 and pump start interlock switch 44 provided in the valve storage section 16a of the housing 10a are connected to the terminal block 280b of the terminal box 28b provided in the housing 10b by cable wiring passing through the cable rack 48.

In addition, a high-voltage cable 53 that supplies AC 100V power is pulled in from the outside into the bulb storage section 16a of the housing 10a. The high-voltage cable 53 is pulled out to the housing 10b side through the cable rack 48 and connected to a terminal on the terminal block 280a of the terminal box 28a. The wiring cable from the terminal block 280a then passes through the first wiring storage section 50 shown in Figure 4 and is connected to the red indicator light 20.

In addition, a low-voltage cable 55, a multi-core cable that supplies 48V DC power, is pulled in from the outside into the valve storage section 16a of the housing 10a. The low-voltage cable 55 is pulled out to the housing 10b side through the cable rack 48 and connected to a terminal on the terminal block 280b of the terminal box 28b. The wiring cable from the terminal block 280b then passes through the first wiring storage section 50 shown in Figure 4 and is connected to the telephone jack 25, answer lamp 26, and transmitter 24 on the electrical door 12.

Note that the low-voltage cable 55 is a single multi-core cable, but in the cable wiring system shown in Figure 6, it is represented as a telephone cable 55a, an answer lamp cable 55b, a transmitter cable 55c, and a switch cable 55d.

As shown in FIG. 7, the pump start switch 42 and the pump start interlock switch 44 are connected to the terminals of the terminal block 280b as a parallel circuit in which the wiring of the pump start interlock switch 44 is connected to the terminal portion of the pump start switch 42. Furthermore, the terminal of the terminal block 280b to which the wiring of the pump start switch 42 and the pump start interlock switch 44 is connected is connected to the terminal to which the wiring of the transmitter 24 is connected via a crossover wiring, so that the wiring of the pump start switch 42 and the pump start interlock switch 44 is connected to the wiring of the transmitter 24.

[b. First wiring storage section]
The first wiring storage section disposed on the rear side of the electrical door will be described in more detail with reference to Figures 8 to 10. Figure 8 shows a wiring structure using the first wiring storage section when the electrical equipment is disposed above the electrical door, Figure 9 shows the first wiring storage section in isolation, and Figure 10 shows the first wiring storage section in a partially cross-sectional side view (A), front view (B), and planar cross section (C). The wiring structure in Figure 8 shows the interior of the wiring storage section in a see-through state.

(b1. Structure of the first wiring storage section)
The first wiring storage section 50 may have any structure, but for example, as shown in Figures 9 and 10(A) and (B), it is composed of a storage body 70, a first opening 72, an elastomer closing member 76 that functions as an elastic closing member, and a second opening 74.

The storage body 70 is a vertically elongated box-shaped component with a height corresponding to a predetermined height range of the door body 12a (see Figure 8) of the electrical door 12, on which the red indicator light 20, transmitter 24, telephone jack 25, and answer lamp 26 are arranged. Mounting plates 80 with mounting holes 82 are integrally formed at the top and bottom ends of the surface facing the back surface of the electrical door 12, and are manufactured, for example, by sheet metal processing.

The first opening 72 is formed with a predetermined width and in a predetermined range corresponding to the vertical arrangement of the electrical equipment on the surface (front) of the storage body 70 opposite the back surface of the door body 12a. As shown in Figure 10 (C), an elastomer closing member 76 is fixed to the back side of the first opening 72 by adhesive or the like to close the opening. The elastomer closing member 76 that closes the first opening 72 has a notch 78 formed in a predetermined vertical range that penetrates through in the thickness direction to allow wiring to the electrical equipment to pass through.

The second opening 74 is used to insert the wiring cables from the terminal boxes 28a, 28b, and can be on any surface other than the surface on which the first opening 72 is formed. However, in this embodiment, since the wiring to the terminal boxes 28a, 28b is routed through the upper part of the housing, it is formed on the upper end surface of the storage body 70.

(b2. Wiring using the first wiring storage section)
The wiring between the terminal boxes 28a, 28b using the first wiring storage section 50 and the electrical equipment arranged on the electrical door 12 will be described in more detail with reference to FIG.

The first wiring storage section 50 is attached and fixed using a support pole 52 and screws 54 at a predetermined distance from the rear surface of the electrical door 12 so as not to interfere with the placement of electrical equipment.

The wiring cable 56 connecting the red indicator light 20 located on the electrical door 12 to the terminal block of the terminal box 28a is routed through the first wiring storage section 50, and on the electrical door 12 side, it is inserted into the notch 78 near the red indicator light 20 in the first opening 72 shown in Figure 9. The wiring cable 56 that passes through the notch 78 is held in the inserted position by the elastic restoring force of the elastomer closing member 76.

In addition, the wiring cables 58, 60, 62 connecting the transmitter 24, telephone jack 25, and answer lamp 26 arranged in the electrical door 12 to the terminal block of the terminal box 28b are also routed through the first wiring storage section 50. On the electrical door 12 side, they are inserted into the notches 78 near the transmitter 24, telephone jack 25, and answer lamp 26 of the first opening 72 shown in Figure 9. The wiring cables 58, 60, 62 that pass through the notches 78 are held in their inserted position by the elastic restoring force of the elastomer closing member 76.

In addition, the wiring cables 58, 60, 62 are slackened midway through their storage in the first wiring storage section 50, forming slack wiring sections 580, 600, 620. If the transmitter 24, telephone jack 25, and answer lamp 26 located above the electrical door 12 are relocated to the lower side of the electrical door 12, the wiring cables 58, 60, 62 can be pulled out toward the electrical door 12, allowing for increased wiring length.

In addition, the wiring cables 56, 58, 60, and 62 are not tied together and are free to run between the first wiring storage section 50 and the electrical door 12, allowing for adjustment of the wiring length. On the other hand, the wiring is tied together with cable ties 66 between the first wiring storage section 50 and the terminal boxes 28a and 28b, preventing adjustment of the wiring length.

(b3. Change in the location of electrical equipment)
The wiring when the arrangement of the electrical equipment arranged on the electrical door is changed will be described in more detail below.

Figure 11 is an explanatory diagram showing a fire hydrant device in which the electrical equipment has been relocated to the underside of the electrical door. The transmitter 24, SOS display board 27, response lamp 26, and telephone jack 25 on the back of the door, which were previously located on the upper side of the electrical door 12 shown in Figure 1, have now been relocated to the underside of the electrical door 12. The previous transmitter placement opening 24a and response lamp placement opening 26a, which became unused due to the relocation of the transmitter 24 and response lamp 26, are now closed with closing plates 240 and 260. In addition, the four screw holes for placing the SOS display board 27 are unused and therefore closed with screws 270.

Figure 12 shows the wiring structure using the first wiring storage section when the electrical equipment is relocated to the underside of the electrical door. As shown in Figure 12, when the positions of the transmitter 24, telephone jack 25, and answer lamp 26 are relocated to the underside of the electrical door 12, the wiring lengths of the wiring cables 58, 60, and 62 connecting the terminal boxes 28, 28b to each electrical equipment become longer. However, before the relocation, as shown in Figure 8, the wiring cables 58, 60, and 62 have slackened wiring sections 580, 600, and 620 formed in the first wiring storage section 50 by loosening the middle portion of the cables. By pulling out the slackened wiring sections 580, 600, and 620 (tightening the slack), the wiring length increases in response to the relocation.

The increase in wiring length that accompanies a change in the location of the electrical equipment is absorbed by the first wiring storage section 50, without affecting the wiring from the terminal boxes 28a, 28b, and the wiring length can be extended while still tied with the cable ties 66. Therefore, even if the location of the electrical equipment is changed, there is no need to cut the cable ties to change the wiring length or change the wiring route, making it possible to simply and easily perform wiring work that corresponds to changes in the location of the electrical equipment.

[c. Second wiring storage section]
The second wiring storage section disposed on the rear side of the electrical door will be described in more detail with reference to Fig. 13 to Fig. 20. Fig. 13 shows a wiring structure using the second wiring storage section when electrical equipment is disposed above the electrical door, Fig. 14 shows the second wiring storage section from the front (A) and side (B), Fig. 15 shows a portion of the second wiring storage section where a wiring fixing member is disposed from the top (A) and front (B), Fig. 16 shows the storage body from the front (A), side (B), and top (C) in partial cross section, Fig. 17 shows the assembled and disassembled state of the wiring fixing member, Fig. 18 shows the wiring fixing member from the front (A), side (B), top (C), back (D), and front cross section (E), Fig. 19 shows the box frame body of the wiring fixing member in an expanded state, and Fig. 20 shows the holding of the wiring cable by the wiring fixing member from the front (A) and back (B).

(c1. Structure of the second wiring storage section)
The second wiring storage section 100 may have any structure, but for example, as shown in Figures 14(A) (B) and 15, it is composed of a storage main body 102, a plurality of wiring fixing members 120 corresponding to electrical equipment (e.g., a red indicator light 20, a transmitter 24, a telephone jack 25, and an answer lamp 26), and a second opening 106.

As shown in Figure 16, the storage unit body 102 is a vertically elongated box-shaped member with a height corresponding to a predetermined range in the height direction of the door body 12a of the electrical door 12. Mounting plates 112 with mounting holes 114 are integrally formed on the upper and lower ends of the surface facing the rear surface of the electrical door 12, and the storage unit body 102 is manufactured, for example, by sheet metal processing.

The first opening 104 is formed with a predetermined width within a predetermined range corresponding to the vertical arrangement of the electrical equipment on the surface (front) of the storage body 102 opposite the rear surface of the door body 12a. Guide rails 108 are arranged on both sides of the first opening 104 in the vertical direction, and a pair of left and right through-holes 110 are formed at a predetermined interval above and below the guide rails 108 for attaching and fixing wiring fixing members 120 corresponding to the arrangement positions of the electrical equipment.

The through holes 110 are provided for attaching and fixing wiring fixing members 120 corresponding to, in order from top to bottom, the red indicator light 20, transmitter 24, telephone jack 25, and answer lamp 26. Below them, there are provided for attaching and fixing wiring fixing members 120 corresponding to the transmitter 24, telephone jack 25, and answer lamp 26 when they are relocated to the lower side of the electrical door 12.

As shown in Figures 15(A) and 15(B), the wiring fixing member 120 is attached and fixed to the guide rail 108 of the storage unit 102 by aligning the screw hole 132 of the rail fixing portion 130 formed on the upper back surface of the wiring fixing member 120 with the through-hole 110 of the guide rail 108 while the rail engagement portion 128 is engaged with the guide rail 108, and then attaching and fixing with the screw 135.

In addition, when the rail engagement portion 128 is engaged with the guide rail 108, the rail fixing portion 130 of the wiring fixing member 120 may be configured to be positioned on the front side (front surface) of the guide rail 108, with the rail fixing portion 130 side serving as a through hole and the guide rail 108 side serving as a tapped hole into which the screw 135 is screwed. In this case, the wiring fixing member 120 can be moved to any position on the guide rail 108 and fixed by screwing in the screw 135.

The wiring fixing member 120 is composed of a metal plate of a box frame main body 122 shown in an exploded view in Figure 19. The exploded box frame main body 122 has a flat portion 122a, a front portion 122b having a front opening 144 cut out in an inverted L shape, a back portion 122c having a rear opening 146 cut out, a left side portion 122d, and a right side portion 122e, which is the upper portion having a screw hole 138 formed therein. The box frame main body 122 having the shape shown in Figures 17 and 18 is manufactured by sheet metal processing. A pair of rail engaging portions 128 for engaging with the guide rails 108 of the storage main body 102 are arranged vertically on the back of the box frame main body 122. A rail fixing portion 130 extends from the upper end of each rail engaging portion 128, and a through-hole 132 is formed therein.

As shown in Figure 17, an L-shaped pivoting frame 134, which forms the bottom and right side of the box frame, is rotatably attached to the lower end of the left side of the box frame body 122 by a hinge 136. The pivoting frame 134 has an elongated hole 142 formed at the end of the right side, and when closed to the underside of the box frame body 122, it can be fixed with a screw 140 through the elongated hole 142 into a screw hole 138 formed in the upper right end of the box frame body 122.

A rectangular elastomer plate member 124 that functions as an elastic plate member is installed and positioned within the box frame body 122 as indicated by arrow 125. A notch 126 is formed in the elastomer plate member 124, running horizontally from the center of the right side, penetrating from front to back to allow for the passage of cable wiring to electrical equipment, such as cable wiring 58 to the red indicator light 20.

To assemble the elastomer plate member 124, for example, with the wiring cable 58 inserted through the notch 126, insert it into the box frame body 122 from diagonally below as shown by arrow 125. Next, press the rotating frame 134 against it from below and tighten the screws 140 passed through the elongated holes 142 into the screw holes 138, thereby fixing the elastomer plate member 124 in a state where it is pressed upward by the rotating frame 134. As the rotating frame 134 is fixed in place, the elastomer plate member 124 is pressed against the box frame body 122, and as shown in Figure 20, the wiring cable 58 inserted through the notch 126 is subjected to a resilient force, which securely holds it in place.

As shown in Figure 16, the second opening 106 of the storage body 102 is used to pass the wiring cables from the terminal boxes 28a and 28b. It can be formed on any surface other than the surface on which the first opening 104 is formed. However, in this embodiment, the wiring to the terminal boxes 28a and 28b is routed through the upper part of the housing, so it is formed on the top end surface of the storage body 102.

(c2. Wiring using the second wiring storage section)
The wiring between the terminal boxes 28a, 28b using the second wiring housing portion 100 and the electrical equipment arranged on the electrical door 12 will be described in more detail with reference to FIG.

The second wiring storage section 100 is attached and fixed using a support pole 52 and screws 54 at a predetermined distance from the rear surface of the electrical door 12 so as not to interfere with the placement of electrical equipment.

As shown in Figures 14 and 15, on the surface of the second wiring storage fabric section 100 facing the electrical door 12, a wiring fixing member 120 is arranged in correspondence with the red indicator light 20 located at the top of the electrical door 12, and the transmitter 24, telephone jack 25, and answer lamp 26 arranged in that order below it.

The wiring cable 56 connecting the red indicator light 20 located on the electrical door 12 to the terminal block of the terminal box 28a is routed through the second wiring storage section 100, and is held in a position on the electrical door 12 side where it passes through the notch 126 of the elastomer plate member 124 provided on the corresponding wiring fixing member 120, as shown in Figure 20.

In addition, the wiring cables 58, 60, and 62 that connect the transmitter 24, telephone jack 25, and answer lamp 26 arranged on the electrical door 12 to the terminal block of the terminal box 28b are also routed through the second wiring storage section 100, and on the electrical door 12 side, they are held in a position where they pass through the notches 126 of the elastomer plate member 124 incorporated into the wiring fixing member 120, which are arranged corresponding to the transmitter 24, telephone jack 25, and answer lamp 26.

In addition, the wiring cables 58, 60, 62 have slackened portions stored in the second wiring storage section 100, forming slack wiring sections 580, 600, 620. If the transmitter 24, telephone jack 25, and answer lamp 26 located on the upper side of the electrical door 12 are relocated to the lower side of the electrical door 12, the corresponding wiring fixing member 120 must also be relocated to the lower side. However, in this case, the wiring cables 58, 60, 62 can be pulled out toward the electrical door 12, allowing for an increase in wiring length.

(c3. Change in the location of electrical equipment)
The wiring when the arrangement of the electrical equipment arranged on the electrical door is changed will be described in more detail below.

Figure 21 shows the wiring structure using the second wiring storage section when the electrical equipment is relocated to the lower side of the electrical door. The transmitter 24, telephone jack 25, and answer lamp 26, which were located above the electrical door 12 shown in Figure 13, have been moved to the lower side of the electrical door 12.

To change the positions of the transmitter 24, telephone jack 25, and answer lamp 26, remove the wiring fixing member 120 through which the corresponding wiring cables 58, 60, and 62 are inserted and fixed in the corresponding position below. At this time, loosen the screws 140 securing the pivoting frame 134 of the wiring fixing member 120 shown in Figure 20, release the wiring cables 58, 60, and 62 inserted through the notches 126 pressed by the elastomer plate member 124, pull out the wiring cables 58, 60, and 62 from the slack wiring portions 580, 600, and 620 stored in the second wiring storage section 100 to increase the wiring length, and then return the pivoting frame 134 to its original position and hold it in place.

The increase in wiring length that accompanies a change in the location of the electrical equipment is absorbed by the second wiring storage section 100, allowing the wiring length to be extended while still tied with the cable ties 66, without affecting the wiring from the terminal boxes 28a, 28b. Therefore, just like the first wiring storage section, the second wiring storage section 100 eliminates the need for wiring work such as cutting the cable ties 66 to change the wiring length or changing the wiring route, even if the location of the electrical equipment is changed, making it possible to simply and easily perform wiring work in response to changes in the location of the electrical equipment.

[d. Third wiring storage section]
The third wiring storage section disposed on the rear side of the electrical door will be described in more detail with reference to Figures 22 and 23. Here, Figure 22 shows a wiring structure using the third wiring storage section when the electrical equipment is disposed on the upper side of the electrical door, Figure 23 shows the third wiring storage section removed, Figure 23(A) shows a front view, Figure 23(B) is a cross section shown by section line b-b in Figure 23(A), and Figure 23(C) is another structure according to the cross section shown by section line b-b in Figure 23(A).

(d1. Structure of the third wiring storage section)
The structure of the third wiring storage section 200 is arbitrary, but for example, as shown in Figure 23 (A), it is composed of a hard elastomer cylindrical body 202, a first opening 204, a soft elastomer closing section 206, a notch section 208, and a second opening 218.

The hard elastomer cylindrical body 202 is a cylindrical body made of a hard elastic material. As shown in Figure 22, it is a vertically elongated cylindrical member with a height corresponding to a predetermined range in the height direction of the door body 12a of the electrical door 12, and is manufactured, for example, by injection molding of hard rubber.

The first opening 204 is formed with a predetermined width in a predetermined range corresponding to the arrangement of electrical equipment in the height direction on the outer surface of the hard elastomer cylindrical body 202, which faces the back surface of the door main body 12a. As shown in Figure 23 (B), the first opening 204 is closed by a soft elastomer closing portion 206 made of soft rubber, which functions as a closing member made of a soft elastic material, and is fixed to the inner surface by adhesive or the like.

The soft elastomer closing member 206 that closes the first opening 204 has a notch 208 formed in a predetermined range in the height direction that penetrates through the thickness direction to allow wiring to electrical equipment to pass through.

As another structure for closing the first opening 204, as shown in Figure 23 (C), a soft elastomer cylindrical body 220 made of a soft elastic material and functioning as a closing member may be placed with its outer surface in close contact with the inner surface of the hard elastomer cylindrical body 202, thereby closing the first opening 204. The soft elastomer cylindrical body 220 has cutouts 208 formed in a predetermined range in the height direction that penetrate through the thickness direction to allow wiring to electrical equipment to pass through.

Mounting plates 210 with mounting holes 214 are disposed on the upper and lower ends of the hard elastomer cylindrical body 202. The mounting plates 210 may be disposed in any configuration relative to the hard elastomer cylindrical body 202, but in this embodiment, the mounting plates 210 are fixed with screws 216 to U-bands 212 fitted into the hard elastomer cylindrical body 202.

The second opening 218 is for inserting the wiring cables from the terminal boxes 28a and 28b. Since the wiring to the terminal boxes 28a and 28b is routed through the upper part of the housing, the upper and lower openings of the hard elastomer cylindrical body 202 serve as the second opening 218.

(d2. Wiring using the third wiring storage section)
The wiring between the terminal boxes 28a, 28b using the third wiring housing section 200 and the electrical equipment arranged on the electrical door 12 will be described in more detail with reference to FIG.

The third wiring storage section 200 is attached and fixed to the mounting plate 210 using the support pole 52 and screws 54, and is positioned a predetermined distance from the rear surface of the electrical door 12 so as not to interfere with the placement of electrical equipment.

The wiring cable 56 that connects the red indicator light 20 arranged on the electrical door 12 to the terminal block of the terminal box 28a is laid out through the third wiring storage section 200, and on the electrical door 12 side, it is inserted into the cutout section 208 near the red indicator light 20 of the first opening 204 shown in Figure 23, and the wiring cable 56 that has passed through the cutout section 208 is held in the inserted position by the elastic force of the soft elastomer closing section 206.

In addition, the wiring cables 58, 60, 62 that connect the transmitter 24, telephone jack 25, and answer lamp 26 arranged in the electrical door 12 to the terminal block of the terminal box 28b are also laid out through the third wiring storage section 200, and on the electrical door 12 side, they are inserted into the cutouts 208 near the transmitter 24, telephone jack 25, and answer lamp 26 of the first opening 204 shown in Figure 23, and the wiring cables 58, 60, 62 that pass through the cutouts 208 are held in the inserted position by the elastic force of the soft elastomer closing section 206.

In addition, the wiring cables 58, 60, 62 are slackened midway through the third wiring storage section 200, forming slack wiring sections 580, 600, 620. If the transmitter 24, telephone jack 25, and answer lamp 26 located above the electrical door 12 are relocated to the lower side of the electrical door 12, the wiring cables 58, 60, 62 can be pulled out below the electrical door 12, allowing for increased wiring length.

In addition, the wiring cables 56, 58, 60, and 62 are not tied together and are free to run between the third wiring storage section 200 and the electrical door 12, allowing for adjustment of the wiring length. On the other hand, the wiring is laid between the third wiring storage section 200 and the terminal boxes 28a and 28b while tied together with cable ties 66, preventing adjustment of the wiring length.

(d3. Changes in the location of electrical equipment)
The wiring when the arrangement of the electrical equipment arranged on the electrical door is changed will be described in more detail below.

Figure 24 is an explanatory diagram showing a fire hydrant device in which the electrical equipment has been relocated to the underside of the electrical door. The transmitter 24, SOS display board 27, response lamp 26, and telephone jack 25 on the back of the door, which were previously located above the electrical door 12 shown in Figure 22, have now been relocated to the underside of the electrical door 12.

As shown in Figure 24, if the positions of the transmitter 24, telephone jack 25, and answer lamp 26 are changed to the lower side of the electrical door 12, the wiring lengths of the wiring cables 58, 60, and 62 connecting the terminal boxes 28, 28b and each electrical device will increase. However, before the position is changed, as shown in Figure 22, the wiring cables 58, 60, and 62 have slackened wiring sections 580, 600, and 620 formed in the middle of the third wiring storage section 200, and the wiring length is increased by pulling out the slack wiring sections 580, 600, and 620.

The increase in wiring length that accompanies a change in the location of the electrical equipment is absorbed by the third wiring storage section 200, without affecting the wiring from the terminal boxes 28a, 28b, and the wiring length can be extended while still tied with the cable ties 66. Therefore, even if the location of the electrical equipment is changed, there is no need to cut the cable ties to change the wiring length or change the wiring route, making it possible to simply and easily perform wiring work that corresponds to changes in the location of the electrical equipment.

[e. Modifications of the present invention]
Modifications of the electrical panel, disaster prevention equipment storage device, and disaster prevention equipment according to the present invention will be described. In addition to the above-described embodiments, the electrical panel, disaster prevention equipment storage device, and disaster prevention equipment according to the present invention include the following modifications.

(Electrical panel of disaster prevention equipment storage device)
The above embodiment takes a fire hydrant as an example of a disaster prevention equipment storage device and is applied to an electrical door provided on the fire hydrant, but it can also be applied to an electrical door for a fire extinguisher box or a standalone reporting device, and further to an electrical door provided on a storage box for disaster prevention equipment installed indoors in a building, etc. It can also be applied to an electrical panel without a door structure that is provided on a disaster prevention equipment storage device.

(Installing electrical equipment on the electrical panel)
In the above embodiment, the electrical panel is formed with multiple openings for each piece of electrical equipment so that changes in the installation position of the electrical equipment can be easily accommodated, and unused openings are closed with closing plates, but the installation method for the electrical equipment is not limited to this.
