Description

The present invention relates to a smoke test instrument used for an operation test of a smoke detector.

Conventionally, fire alarm equipment has been installed in buildings such as offices, and when a fire breaks out, the smoke generated by the fire is detected by a smoke detector and a warning signal is sent to the receiver to issue a fire alarm. It is output so that fire extinguishing, evacuation, and firefighting activities can be carried out.

The fire alarm system is regularly inspected after it is installed in the building, and the smoke detector is subjected to an operation test using smoke test equipment.

As a smoke test instrument used for the operation test of the smoke detector, a smoke spray can or an incense stick is used (Patent Document 1).

However, according to the smoke test equipment using a smoke spray can, the price is high because it uses chlorofluorocarbons, and it is expected that the price will rise because it will be difficult to obtain alternative chlorofluorocarbons in the future. Since it is not easy to control the amount, there is a problem that the inspection work efficiency is poor.

In addition, according to the smoke test equipment using incense sticks, the smell is strong, so it is reluctant to use it in buildings where many people gather, especially in hospitals, and the quantity that can be inspected with one incense stick is limited. However, there was a problem that the inspection work efficiency was poor because there was a possibility that it would disappear on the way.

In order to solve such a problem, in the smoke test instrument of Patent Document 2, smoke is emitted from the tip portion in a sensor cover provided via a support rod that can be expanded and contracted with respect to the operation portion. A body is provided, and the smoke generator is equipped with a heater and a liquid supply unit impregnated with a water-soluble liquid in the cylinder. When conducting a test, air is sent from the blower unit into the cylinder, and the water-soluble liquid vaporized by heating with a heater. Is atomized to emit simulated smoke to test smoke detectors.

According to such a smoke test jig, simulated smoke atomized by vaporization of a water-soluble liquid is generated. Therefore, viscous oil smoke or the like adheres to the smoke detector or the ceiling surface to stain the smoke detector or the ceiling surface. Further, it is possible to perform an operation test of the smoke detector while avoiding the adhesion of dust and the like.

The operation unit 12 is formed with a spray can storage unit 32 for storing a smoke spray can filled with freon gas, and the spray can storage unit 32 is replaced with a smoke spray can and is a smoke spray as shown in FIG. A smoke emitting device 36 having the same outer shape as the can is housed.

The smoke spray can used for the smoke generator 36 has an outer size of, for example, 50 mm in diameter and 150 mm in height, and the smoke device 36 has an outer size of 50 mm in diameter and 150 mm in height, which is the same as the smoke spray can. Therefore, the smoke emitting device 36 can be stored and used in the spray can storage unit 32 in the same manner as the smoke spray can by removing the cap 35.

A switch 54 is arranged on the upper part of the smoke emitting device 36, and a switch lever 55 is provided on the switch 54. Correspondingly, the operation unit 12 is provided with an operation lever 18 that is rotatable by a support shaft 20 and a link lever 34 that transmits the movement of the operation lever 18, and a spray is provided at the tip of the link lever 34.

When the switch 54 is turned on, the smoke generator 36 atomizes the water-soluble liquid vaporized by heating by energizing the heater to generate pseudo smoke, and emits the simulated smoke generated in the sensor cover 16 via the support rod 14.

When the spray can is stored in the spray can storage unit 32, when the operation lever 18 is pulled with a finger, the link lever 34 is pushed downward, so that the pressing switch on the upper part of the spray can is pressed and gas is ejected. It was to be done. Since the switch lever 55 of the smoke emitting device 36 operates by pushing the link lever 34 downward in the same manner as the spray can ejection operation, the structure of the operating lever 18 and the switch lever 55 of the smoke testing instrument does not need to be changed. is there. Therefore, the smoke generator 36 can be used as an alternative to the spray can of the existing smoke tester.

The support rod 14 is detachably attached to the tip end side of the operation portion 12, and in the present embodiment, the first pipe member 22 detachably connected to the operation portion 12 and the first pipe member 22 It is composed of a second pipe member 24 that is inserted into the pipe and is slidable in the axial direction.

The first pipe member 22 and the second pipe member 24 have a hollow pipe structure, and have an internal passage for discharging smoke from the opening at the tip, and the inner diameter of the pipe member serving as the internal passage is, for example, It is 10 mm or more, and practically around 20 mm is desirable.

Further, as the length of the support rod 14 due to the two-stage pipe structure of the first pipe member 22 and the second pipe member 24, the minimum length of the second pipe member 24 drawn into the first pipe member 22 is about 1 meter. Then, the length when the second pipe member 24 is pulled out to the maximum is about 2 meters. The rubber stopper 25 holds the pull-out position of the second pipe member 24 pulled out from the first pipe member 22.

Further, the first pipe member 22 and the second pipe member 24 are made of, for example, a highly insulating and lightweight material of FRP resin, and have extremely high resistance even when testing a smoke detector such as that provided in high-voltage electrical equipment. Insulation is guaranteed and the weight is reduced.

The tip of the second pipe member 24 serves as a smoke discharge port, and a diffusion guide 26 is attached thereto. The diffusion guide 26 spreads the smoke sent through the internal passage in the support rod 14 so as to wrap around the smoke detector 30 installed on the ceiling surface or the like. Further, a sensor cover 16 is attached to the diffusion guide 26.

The sensor cover 16 is integrally composed of a funnel-shaped windbreak cover portion 27 and a bellows-structured cushion portion 28. The sensor cover 16 is positioned so as to cover the outside of the smoke detector to be tested, and is made of a material such as transparent ABS resin or silicone rubber so that the inside can be seen. The smoke detector 30 emits smoke for testing. The operator can easily check the lighting of the alarm indicator lamp from below when it is received and operated. The sensor cover 16 is used for an operation test of a smoke detector installed in a place receiving the wind blown from the air conditioner.

In addition, smoke may flow into the smoke detector from the diffusion guide 26 without using the sensor cover 16.

[Smoke generator]
FIG. 3 is an explanatory view showing a smoke generator having the same outer shape as that of a smoke spray can, and FIG. 3 (A) shows the appearance and FIG. 3 (B) shows the internal structure. Further, FIG. 4 is an explanatory view showing an embodiment of the smoke emitting cartridge in cross section, and FIG. 5 is an explanatory view showing a state in which the smoke emitting device is disassembled in order to replace the smoke emitting cartridge.

(Configuration of smoke generator)
As shown in FIG. 2, the smoke emitting device 36 includes a cylindrical housing 38 having the same outer size as the smoke spray can, for example, a diameter of 50 mm and a height of 150 mm. In the present embodiment, the housing 38 is high. It can be separated into an upper case 38a and a lower case 38b which are divided in half in the longitudinal direction, and are connected by a central connecting portion 38c. The lower case 38b is provided with a ventilation hole 38d.

Further, the material of the housing 38 may be a metal case or a synthetic resin case. Further, the housing 38 does not necessarily have to have a closed structure, and may have a frame shape that can be stored in the spray can storage portion 32 shown in FIG.

Inside the housing 38 of the smoke generator 36, a rechargeable battery 42 such as a lithium ion battery, a blower pump 44 that functions as a blower, an airflow detection part 48, a control part 50, and a smoke cartridge 60 that can be attached and detached by a connector 56 are provided. It has been incorporated.

For example, a piezoelectric pump is used for the blower pump 44 in order to reduce the size. The pressurized air driven by the blower pump 44 is sent out through the air pipe 46 and is sent to the cylindrical cases 52a and 52b. An airflow detection unit 48 and a control unit 50 mounted on a circuit board are arranged in the cylindrical case 52a. Further, in the cylindrical case 52b, a smoke emitting cartridge 60 that is detachably provided by a connector 56 with respect to the control unit 50 is housed.

As shown by the broken line, the pressurized air sent from the blower pump 44 through the air pipe 46 passes around the airflow detection unit 48 in the cylindrical case 52a to the control unit 50, and the smoke cartridge 60 of the cylindrical case 52b. It is sent into the inside from the portion of the connector 56, passes around the smoke cartridge 60, and is discharged from the discharge port 53 at the upper end of the cylindrical case 52b. The airflow detection unit 48 detects the airflow flowing in the cylindrical case 52a and outputs an airflow detection signal to the control unit 50.

A switch 54 is arranged on the upper outer side of the upper case 38a in the housing 38, and the switch 54 operates by pushing the switch lever 55 to output an on signal to the control unit 50.

A connector 58 is provided on the outside of the cylindrical case 52a, and connects a signal line 57 from the switch 54, a power supply line 43 from the battery 42, a control line 59 for the blower pump 44, and the like to the control unit 50.

When the control unit 50 detects an ON signal of the switch 54 by pushing the switch lever 55 via the link lever 34 by operating the operation lever 18 shown in FIG. 2, it drives the blower pump 44 and sends pressurized air to the air pipe. Control is performed so that the pipes are fed from the 46 to the cylindrical cases 52a and 52b, and a part of the pumps is fed into the smoke emitting cartridge 60.

When the control unit 50 detects an air flow by the air flow detection signal of the air flow detection unit 48 provided in the cylindrical case 52a, the control unit 50 energizes and heats the heater built in the smoke generation cartridge 60 to heat the inside of the smoke generation cartridge 60. By vaporizing the water-soluble solution for smoke that is impregnated in the liquid supply unit incorporated in the cylinder case 52b, simulated smoke is emitted and controlled to be discharged from the discharge port 53 of the cylindrical case 52b.

(Smoke cartridge)
As shown in FIG. 4, in the smoke emitting cartridge 60, a rod-shaped liquid supply unit 68 is housed inside the tubular body 62, a heater 70 is wound around the liquid supply unit 68, and the lower side of the heater 70 is a connector 56. It is connected to the connection pins 56a and 56b.

The inflow port 64 is opened at the lower end of the tubular body 62, and the pressurized air sent from the blower pump 44 in FIG. 3 is introduced into the tubular body 62 as shown by an arrow. Further, a discharge port 66 is opened in the upper part of the tubular body 62, and the air introduced from the inflow port 64 is discharged upward.

The liquid supply unit 68 is formed by forming a fiber-based nonflammable filter such as glass fiber or a nonflammable filter made of foamed resin in a rod shape, and the filter has a large number of voids opened so as to be ventilated in all directions of the surface. The pores are formed inside, and the void pores are impregnated with a predetermined water-soluble liquid serving as a smoke generator.

A heater 70 using a metal wire such as a nichrome wire or a platinum wire is spirally wound around the liquid supply unit 68, and the water-soluble liquid impregnated in the liquid supply unit 68 is brought into contact with the heater 70 to bring the heater 70 into contact with the heater 70. The water-soluble liquid impregnated in the liquid supply unit 68 is vaporized by heating by energizing the liquid, and is put on an air stream and discharged from the discharge port 66 to generate atomized simulated smoke (aerosol).

As the water-soluble liquid to be impregnated in the liquid supply unit 68, a water-soluble liquid having hydrophilicity and high water retention, for example, a water-soluble liquid containing at least one of components such as glycerin and propylene glycol, which is harmless to the human body, is used. Has been done.

When a water-soluble liquid containing components such as glycerin and propylene glycol impregnated in the liquid supply unit 68 is heated by the heater 70 and vaporized, the components such as glycerin and propylene glycol evaporate together with water and are emitted from the discharge port 66. After that, it cools and becomes a nucleus, and water vapor aggregates on it to form white smoke, which produces pseudo-smoke.

In the simulated smoke generated in this way, propylene glycol and glycerin are highly hydrophilic, take in the evaporated water, and have a high effect of preventing the vaporization of the taken-in water, so that the white smoke is relatively long. It will float in the air over time.

(Cartridge replacement)
As shown in FIG. 5, when replacing the used smoke cartridge 60, the upper case 38a is removed from the lower case 38b of the housing 38 and the inside of the lower case 38b is removed from the smoke emitting device 36 taken out from the smoke testing instrument. The cylindrical cases 52a and 52b housed in the above are exposed, and then the cylindrical case 52b is removed to expose the smoke cartridge 60.

Since the smoke cartridge 60 is connected to the control unit 50 side by the connector 56, the used smoke cartridge 60 is removed and replaced with a new smoke cartridge.

[Test work with smoke test equipment]
Next, an operation test of the smoke detector using the smoke test device 10 of the present embodiment will be described.

As shown in FIG. 1, in order to perform an operation test of the smoke detector 30 with the smoke test device 10, the smoke detector 30 installed on the ceiling surface is covered with the sensor cover 16 and the peripheral end of the sensor cover 16 is covered. Make the edges stick to the ceiling.

When the operating lever 18 is pulled in this state, the switch 54 provided in the smoke generating device 36 is turned on by pushing down the switch lever 55 via the link lever 34 by rotating the operating lever 18 around the support shaft 20.

When the switch 54 is turned on, the control unit 50 of the smoke emitting device 36 shown in FIG. 3 detects that the switch 54 is turned on and drives the blower pump 44, and the smoke emitting cartridge via the cylindrical cases 52a and 52b via the air pipe 46. Pressurized air is sent to 60 and is sent through an internal passage around the smoke cartridge 60.

When the signal level of the airflow detection signal from the airflow detection unit 48 provided in the cylindrical case 52a increases due to the airflow from the blower pump 44, and the airflow detection signal reaches a predetermined threshold level or higher in the control unit 50, FIG. The heater 70 provided in the smoke cartridge 60 shown is energized to heat it. Since the heater 70 is not energized unless the airflow to the smoke emitting cartridge 60 is increased in this way, it is possible to prevent abnormal heating due to energization of the heater 70 when there is no airflow or when the airflow is low.

When the liquid supply unit 68 is heated by energizing the heater 70, the water-soluble liquid containing components such as glycerin and propylene glycol impregnated in the liquid supply unit 68 is vaporized and released by the pressurized air from the blower pump 44. When discharged from the outlet 66, it is atomized and simulated smoke is generated.

The simulated smoke emitted from the smoke cartridge 60 is sent upward through the internal passage of the support rod 14 by the air flow sent from the blower pump 44 around the smoke cartridge 60, and diffuses at the tip of the support rod 14. It is discharged from the guide 26 into the sensor cover 16.

At this time, if the smoke detector 30 is operating normally, when the pseudo smoke reaches a predetermined concentration, the smoke detector 30 issues a warning signal and transmits a warning signal to the receiver to output a warning sound. Further, the alarm indicator lamp provided on the smoke detector 30 is turned on, and it can be confirmed that the smoke detector 30 has operated normally.

Here, when the operation test of the first smoke detector is performed using the smoke test device 10, the simulated smoke generated by the smoke generator 36 of the operation unit 12 passes through the internal passage of the support rod 14 to cover the sensor. It takes some time for the smoke detector 30 to be sent into the 16 and reach the concentration reported by the smoke detector 30. However, in the operation test of the second and subsequent smoke detectors, the simulated smoke generated in the previous test stays in the internal passage of the support rod 14, and when the operation lever 18 is operated and the switch 54 is turned on, the smoke stays. By immediately sending out the simulated smoke to the inside of the sensor cover 16, it is possible to obtain the concentration that the smoke detector issues in a short time with almost no time delay.

When the operation test of the smoke detector is repeated using the smoke test instrument 10, the amount of water-soluble liquid impregnated in the liquid supply unit 68 of the smoke cartridge 60 may decrease, and the amount of smoke emitted may decrease. is there.

In this case, the cap 35 provided at the bottom of the operation unit 12 of the smoke test instrument 10 is removed, the smoke generator 36 is taken out, the housing 38 is disassembled as shown in FIG. 5, and the smoke cartridge 36 is replaced with a new one. Replace with. When the smoke cartridge 60 is used up in this way, it can be easily replaced with a new one.

When the smoke emitting cartridge 60 is used up, the smoke emitting device 36 may be replaced with an unused new one. The used smoke generator 36 can be reused by disassembling the smoke generator 36 as shown in FIG. 5 and replacing the smoke cartridge 60 separately.

[Embodiment without airflow detector]
As another embodiment of smoke generation according to the present invention, the configuration may be such that the airflow detection unit 48 provided in the smoke generation device 36 of FIG. 3 is excluded.

In the embodiment having no airflow detection unit 48, when the control unit 50 detects the ON operation of the switch 54, in addition to the driving of the blower pump 44, to energize the heating of the heater 70 incorporated in the smoke cartridge 60 ..

Even if the airflow detection unit 48 is not provided in this way, the pressurized air is sent to the smoke generation cartridge 60 by driving the blower pump 44, so that the airflow passing through the smoke generation cartridge 60 is not interrupted and the heater 70 Since there is no possibility that abnormal heating will occur, it is possible to operate normally without providing the airflow detection unit 48 in practical use.

The proximity switch 74 operates and turns on when the smoke detector 30 approaches the ceiling surface on which the smoke detector 30 is installed within a predetermined distance. As the proximity switch 74, for example, an infrared proximity switch provided with a light emitting unit and a light receiving unit is used.

The control unit 50 of the smoke generator 36 shown in FIG. 3 drives the blower pump 44 when the ON signal from the proximity switch 74 is detected, and the level of the airflow detection signal of the airflow detection unit 48 is equal to or higher than a predetermined threshold level. Then, the heater 70 provided in the smoke emitting cartridge 60 shown in FIG. 4 is energized to vaporize the water-soluble liquid impregnated in the liquid supply unit 68 to generate pseudo smoke, which is discharged into the sensor cover 16. Let me.

In addition, instead of the proximity switch 74, a switch that is operated and turned on by operating the operation lever 18 of the operation unit 12 is provided, and the on signal is transmitted to the smoke generation device 36 stored in the smoke generation test unit 74 by a signal line or wirelessly. It may be transmitted to the device to perform an operation of emitting simulated smoke.
