Description

  The present invention relates to an underground installation structure for a control device in which a control device for controlling a street light or the like is installed underground.

  In Patent Document 1, a charging means for storing electric power generated by a generator is embedded in a street light pole provided with a power generation means installed in an urban area, a park, or the like to make the space compact. In addition, street lights that do not impair the landscape are disclosed. However, when the generator becomes complicated and the equipment such as a control panel for controlling the generator becomes complicated and large, the installation area is limited in the street light described in Patent Document 1, and the control is performed. There is a possibility that equipment such as a panel cannot be installed. Therefore, as shown in Patent Document 2, a buried facility in which such a facility is installed underground has been proposed. The burying equipment of patent document 2 has fixed the lower end part and upper end part of the storage container which cover and store the whole equipment main parts, such as a control panel, from the upper part, respectively. When the underground space (hand hole) where the equipment is installed is submerged, buoyancy equivalent to the weight of the water displaced by the container is generated, so fixing the container prevents the container from floating. It is designed to protect the equipment from flooding.

  However, since the embedding facility of Patent Document 2 must fix the storage container, the underground space in which the facility is installed becomes large, and in order to prevent inundation, it is necessary to strengthen the fixing portion of the storage container. Yes, each time the equipment in the container is operated, the fixed part must be removed, which requires time and effort.

  Therefore, an object of the present invention is to provide an underground installation structure for a control device that can protect the control device with a simple structure.

Means and effects for solving the problems

The present invention comprises a storage room for storing control equipment, a concrete base buried in the ground, a storage room opened on the top surface of the concrete base, and a container having only the lower end opened, are housed in, comprising a substantially protective cover of the same size as the-holding tube chamber, when accommodating the protective cover in the storage chamber, the state in which almost gap not interposed between the protective cover and-holding tube chamber Wiring from the control device housed in the internal space of the protective cover is to be controlled from a lower end opening of the protective cover through a gap formed in the concrete base, such as a street light Furthermore, the protective cover is set to have a weight that is greater than the buoyancy when the storage room is submerged. According to this, when the storage room is submerged, the control device can be prevented from being exposed to water, and the control device can be protected. Since the protective cover is only put on the control device, when the storage room is submerged, the buoyancy corresponding to the weight of the water that the protective cover has pushed off is generated and the control device is exposed to water. However, since the weight of the protective cover is set to be equal to or greater than the buoyancy, the protective cover is not lifted and the control device can be prevented from being exposed to water.

Further, in another aspect, and concrete substrate was buried in the ground, forms a storage chamber which is opened to the upper surface of the concrete base, the container shape which is opened only lower end side is accommodated in the storage chamber, the storage and substantially and a protective cover of the same size, when accommodating the protective cover in the storage chamber is made of a state in which almost gap not interposed between the protective cover and-holding pipe chamber, And the wiring from the control device accommodated in the internal space of the protective cover is connected to the controlled object such as a street light from the opening on the lower end side of the protective cover through the gap formed in the concrete base, Further, the protective cover is connected to the control device when the control device is accommodated, and the total weight with the control device is set to be equal to or more than the buoyancy when the storage room is submerged. According to this, when the storage room is submerged, the control device can be prevented from being exposed to water, and the control device can be protected. Since the total weight of the protective cover and the control device is set to be equal to or greater than the buoyancy generated in the protective cover when the storage room is submerged, the range in which the material of the protective cover can be selected can be expanded.

  Moreover, it is preferable that the storage room of this invention has the drainage means to drain. According to this, since the water which entered the storage chamber can be drained, the flooding of the storage chamber can be prevented. In this case, the drainage means may have a backflow prevention means for preventing water from flowing in the direction opposite to the drainage direction. According to this, it is possible to prevent the control device from flowing back and water from entering the protective cover, thereby protecting the control device. Further, the protective cover of the present invention may be fixed. According to this, even when the storage room is submerged, the protective cover can be reliably prevented from floating. Furthermore, the storage room of the present invention may be sealed. According to this, it becomes difficult for the storage room to be submerged.

  It is preferable that the control device of the present invention is installed at a position higher than the position where the air existing in the internal space of the protective cover prevents water from entering the internal space. According to this, even when water enters the protective cover, the risk of the control device being immersed in water can be reduced, and the control device can be protected from water immersion.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
The underground installation structure of the control apparatus of this invention is used suitably for a street lamp 1 etc. as shown in FIG. In the present embodiment, the case where the present invention is applied to a street lamp will be described. However, the present invention is not limited to a street lamp. For example, the present invention is applied to an apparatus that requires a control device such as a wind power generator. The present invention can be suitably used. The street lamp 1 is installed along a park or along a road, and includes a lamp 12, a pole 13, a solar cell 14, and a storage room 3.

  The pole 13 supports the lamp 12 and the solar cell 14 and is embedded so as to be substantially perpendicular to the ground. The embedded portion of the pole 13 is fixed by the concrete 15 with a strength capable of withstanding strong winds such as typhoons. Yes. Although not shown, the pole 13 has a space through which wiring for connecting the lamp 12, the solar cell 14, and the control device 10 described later can pass. The top surface of the concrete 15 is at the same position as the ground level.

  The lamp 12 is a lighting fixture that is installed above the pole 13 and illuminates a dark place such as at night, and is composed of a fluorescent lamp, a white LED, and the like. The white LED is formed, for example, by applying a YAG-based phosphor on the surface of a blue light emitting diode, and part of the blue light passes through the phosphor layer, and the rest collides with the phosphor to produce yellow light. It is configured to emit the mixed color (white color) when it becomes. When the lamp 12 is a white LED, lighting may be repeatedly turned on and off at intervals that are not perceived by the human body, and certain information data may be included in the on and off. In this case, a passerby near the street lamp 1 can obtain various information by receiving this information data.

  The solar cell 14 is a solar power generation device installed at the upper end of the pole 13 and generates electric power required by the lamp 12 installed below the solar cell 14. Since the street lamp 1 has the generator of the solar cell 14, it is not necessary to wire an electric wire or the like for supplying necessary power to the lamp 12 from the outside. Moreover, even if a power failure occurs due to a disaster or the like, the lamp 12 can be used. In addition, such a power generation device may use wind energy, hydraulic power, or other natural energy.

  The storage chamber 3 is a substantially rectangular or cylindrical space formed in the concrete 15 in the vicinity of the pole 13 and partially opened, and a control device 10 for controlling the lamp 12 and the solar cell 14 is installed. . Moreover, the control apparatus 10 is mounted on the stand 11, and is installed so that it may be isolated from the bottom face of the storage room 3 (vacancy). Specifically, the control device 10 is installed at a position higher than the position where the air existing in the internal space of the protective cover 2 prevents water from entering the internal space. Here, the control device 10 includes a control unit that controls the lamp 12, a charging unit such as a storage battery that charges power generated by the solar cell 14, and an adjustment unit that adjusts the power generation amount of the solar cell 14. Although not shown, the concrete 15 is provided with a gap that leads from the bottom surface of the storage chamber 3 to the inside of the pole 13, and can pass through the wiring that connects the control device 10, the lamp 12, and the solar cell 14, respectively. It is like that.

  In the storage chamber 3, a protective cover 2 having a substantially square shape with a hollow inside and a part opened is installed so that the opening portion and the bottom surface of the storage chamber 3 are in close contact with each other. The protective cover 2 covers the control device 10 so as to cover the control device 10 from above, thereby accommodating the control device 10 in the internal space and preventing water from entering the internal space from the opening due to air existing in the internal space. It can be done. Furthermore, the protective cover 2 is made of a material having a sufficiently large weight, that is, a weight higher than the buoyancy applied to the protective cover 2 so that the protective cover 2 does not float due to the buoyancy generated when the storage chamber 3 is submerged.

Specifically, the size of the buoyancy acting on the object is equal to the weight of the fluid (water) displaced by the object, and the specific gravity of water is 1 [g / cm ³ ]. When the mass is h, the protective cover 2 is made of a material that satisfies h> c, that is, the specific gravity γ of the protective cover 2 satisfies γ = h / c> 1. The protective cover 2 is preferably processed so as to prevent corrosion and the like.

  Further, the size of the protective cover 2 is substantially the same as that of the storage chamber 3, that is, there is almost no gap between the storage chamber 3 and the protective cover 2. Thereby, the amount of water when the storage chamber 3 is submerged is reduced, and by providing the drainage structure 5 described later, the amount of water present in the storage chamber 3 can be reduced as much as possible, and thereby the protective cover 2 is generated. The buoyancy can be reduced.

  A drainage structure 5 is provided on the bottom surface of the storage chamber 3. The drainage structure 5 has water discharge holes both inside the protective cover 2 and in the gap between the protective cover 2 and the storage chamber 3. As a result, it is possible to prevent the storage chamber 3 from being submerged, and at the same time to discharge the water that has entered the internal space of the protective cover 2. Further, the drainage structure 5 is provided with a backflow prevention valve 5a (backflow prevention means) for preventing backflow. The backflow prevention valve 5a has a structure in which, for example, when backflow occurs, the valve is covered with backflow pressure. As a result, water can be prevented from entering the protective cover 2 from the drainage structure 5. In addition, the drainage structure 5 may just provide a drain hole in the bottom face of the storage chamber 3, and may drain with a pump etc.

  Furthermore, the opening part of the storage chamber 3 has a lid 4 for sealing the storage chamber 3. The lid 4 is installed so that it can be opened and closed. The lid 4 may be merely placed on the storage chamber 3, or may be installed so that one end is rotatably fixed and the other end can be opened and closed. By sealing the storage chamber 3 with the lid 4, it is possible to prevent water from entering the storage chamber 3 from the outside.

  Next, the case where the storage room 3 of the underground installation structure of this Embodiment is flooded is demonstrated concretely.

  Since the storage chamber 3 is sealed by the lid 4, water is prevented from entering the storage chamber 3, but water may enter the storage chamber 3 due to heavy rain or flooding. In such a case, buoyancy is generated in the protective cover 2 when the water gradually enters and the storage chamber 3 is submerged. As described above, the protective cover 2 is made of a material having a weight greater than or equal to the buoyancy, so that it does not float even when the storage chamber 3 is submerged. Since the protective cover 2 is only put on the control device 10, when the storage chamber 3 is submerged, buoyancy is generated in the protective cover, and the control device is exposed to water. Since the weight is set, the protective cover does not float and the control device 10 can be prevented from being exposed to water.

  In addition, for example, even when a strong shaking occurs due to an earthquake or the like, the protective cover 2 slightly floats and water enters the internal space, the water in the internal space of the protective cover 2 does not rise above a certain level. In addition, since the control device 10 is placed on the base 11 and installed separately from the bottom surface of the storage chamber 3, the control device 10 can be prevented from being immersed in water. Even when water enters a certain level in the protective cover 2, the drainage structure 5 is provided inside the protective cover 2, so that it can be discharged quickly and the control device 10 can be protected. ing. Furthermore, it is possible to prevent water from flowing back from the drainage structure 5 by the air in the internal space of the protective cover 2 and entering the inside of the protective cover 2.

  In addition, since the drainage structure 5 is also provided in the gap portion between the storage chamber 3 and the protective cover 2, even when the storage chamber 3 is submerged, it can be drained quickly. ing. Furthermore, since there is almost no gap between the storage chamber 3 and the protective cover 2, the amount of water in the storage chamber 3 hardly exists by draining from the drainage structure 5, and the buoyancy applied to the protective cover 2 is reduced. Can be done. As a result, the protective cover 2 can be prevented from floating.

  Next, the installation process of the underground installation structure of this Embodiment is demonstrated.

  First, a place where the street light 1 is to be installed is excavated, and a pole 13 is embedded in the excavated portion. At this time, the pole 13 is embedded so that the periphery of the pole 13 is fixed by the concrete 15 so as to have a strength that can withstand strong winds. A space is provided in the vicinity of the pole 13 to form the storage chamber 3 and the drainage structure 5. The storage chamber 3 and the drainage structure 5 may be formed by excavating the concrete 15. When the pole 13 is fixed, the storage chamber 3 and the drainage structure 5 prepared in advance are installed. At the same time, it may be fixed with concrete 15. Thereafter, the control device 10 is placed on the table 11 and the protective cover 2 is put on. Finally, the lid 4 is installed so as to seal the storage chamber 3. In addition, as shown in FIG. 5, you may just embed what formed the pole 13, the concrete 15, the storage chamber 3, and the drainage structure 5 previously.

As described above, the present embodiment has a concrete base (concrete 15) embedded in the ground, a storage chamber 3 opened on the upper surface of the concrete 15, and a container shape opened only on the lower end side. form, is housed in the storage chamber 3, comprises a substantially protective cover 2 of the same size as the-holding tube chamber, when accommodating the protective cover 2 in the storage chamber 3, the protective cover 2 and-holding tube The wiring from the control device 10 in which there is almost no gap between the chamber 3 and accommodated in the internal space of the protective cover 2 is routed from the opening on the lower end side of the protective cover 2 to the concrete. 15 is connected to an object to be controlled such as a street light 1 through a gap formed in 15, and the protective cover 2 is set to have a weight equal to or greater than the buoyancy when the storage chamber 3 is submerged.

  According to this, when the storage chamber 3 is submerged, the control device 10 can be prevented from being exposed to water, and the control device 10 can be protected. Since the protective cover 2 is only put on the control device 10, when the storage chamber 3 is submerged, buoyancy is generated in the protective cover 2, and the control device 10 is exposed to water. However, since the protective cover 2 is set to have a weight greater than the buoyancy, the protective cover 2 is not lifted, and the control device 10 can be prevented from being exposed to water.

  Moreover, since the storage chamber 3 of the present invention has the drainage means 5 for draining, the flooding of the storage chamber can be prevented. Moreover, since the storage chamber 3 is sealed, the storage chamber is not easily flooded. In this case, the backflow prevention valve 5 a is provided, and water can be prevented from entering the protective cover 2. Furthermore, since the control device 10 is installed at a position higher than the position where the air existing in the internal space of the protective cover 2 prevents the water from entering the internal space, water has entered the protective cover. Even if it is a case, the possibility of being immersed in water can be reduced and can be protected.

  Moreover, although this invention was demonstrated based on suitable embodiment, this invention can be changed in the range which does not exceed the meaning. That is, as shown in FIG. 2, the anti-lifting lever 6 may be provided so that the protective cover 2 does not lift up reliably. Specifically, when the concave portion is provided on the side wall of the storage chamber 3 at substantially the same height as the upper surface of the protective cover 2 and the rod-shaped anti-floating lever 6 is inserted, the protective cover 2 is lifted. 2 may be received so that the protective cover 2 does not float. Moreover, although not shown, you may fix so that it may not move in a horizontal direction.

  Furthermore, as shown in FIG. 4, a wind power generation 16 may be installed on the pole 13. For example, even if the solar cell 14 cannot sufficiently generate power during the daytime due to wind and rain, etc., by providing the wind power generation 16, it is possible to generate power according to changes in the external environment.

  The storage chamber 3 may not be sealed with the lid 4 and may not have the drainage structure 5. The control device 10 may not be installed separately from the bottom surface of the storage chamber 3. The shapes of the protective cover 2 and the storage chamber 3 are not limited to the above-described embodiment. Further, the backflow prevention valve 5a may be installed or may not be installed.

(Second Embodiment)
Next, an underground installation structure according to the second embodiment of the present invention will be described. This embodiment is different from the first embodiment in that the protective cover 2 and the control device 10 are connected. Specifically, as shown in FIG. 3, a convex portion protruding in an L shape is provided on the inner wall surface of the protective cover 2. And the stand 7 has a flat plate shape that is bent downward in an L shape so that the end portion is fitted to the convex portion of the protective cover 2. Such a fitting portion can be removed by slightly shifting the protective cover 2 and the control device 10 in the horizontal direction. The control device 10 is placed on the table 7. Thereby, the protective cover 2 and the control apparatus 10 are connected and integrated.

  The total weight of the integrated protective cover 2 and the control device 10 is set to be equal to or greater than the buoyancy generated in the protective cover 2 when the storage chamber 3 is submerged. Thus, even when the storage room 3 is submerged, the protective cover 2 does not float, and even when the protective cover 2 floats due to a shake such as an earthquake, the control device 10 also floats together with the protective cover 2. Is not soaked in water. Moreover, the range which can select the material of the protective cover 2 can be expanded now by connecting the protective cover 2 and the control apparatus 10. FIG. For example, if the total weight of the protective cover 2 and the control device 10 is larger than the buoyancy applied to the protective cover 2, a resin material that is light and hardly corrodes may be used.

As described above, the present embodiment has a concrete base (concrete 15) embedded in the ground, a storage chamber 3 opened on the upper surface of the concrete 15, and a container shape opened only on the lower end side. form, is housed in the storage chamber 3, comprises a substantially protective cover 2 of the same size as the-holding tube chamber, when accommodating the protective cover 2 in the storage chamber 3, the protective cover 2 and-holding tube The wiring from the control device 10 in which there is almost no gap between the chamber 3 and accommodated in the internal space of the protective cover 2 is routed from the opening on the lower end side of the protective cover 2 to the concrete. 15 is connected to an object to be controlled such as a street lamp 1 through a gap formed in 15, and the protective cover 2 is connected to the control device 10 when the control device 10 is accommodated, and the total weight with the control device 10 is When storage room 3 is submerged It is set on the weight of more than force. According to this, when the storage chamber 3 is submerged, the control device 10 can be prevented from being exposed to water, and the control device 3 can be protected. Since the total weight of the protective cover 2 and the control device 10 is set to be greater than or equal to the buoyancy generated in the protective cover when the storage chamber 3 is submerged, the range in which the material of the protective cover 2 can be selected can be expanded.

  Although the present invention has been described in the preferred embodiments above, the present invention is not so limited. It will be understood that various other embodiments may be made without departing from the spirit and scope of the invention. Furthermore, in this embodiment, although the effect | action and effect by the structure of this invention are described, these effect | actions and effects are examples and do not limit this invention.
