Description

  The present invention relates to a smoke test apparatus used for a smoke sensor operation test.

  Conventionally, a fire alarm system is installed in a building such as an office, and when a fire occurs, smoke generated by the fire is detected by a smoke detector, a notification signal is sent to a receiver, and a fire alarm is generated. It makes it possible to output, extinguish, evacuate and firefighting activities.

  The fire alarm system is regularly inspected after installation in a building, and the smoke detector is subjected to an operation test using a smoke test apparatus.

  A smoke spray can or incense stick is used as a smoke test device used for a smoke sensor operation test (Patent Document 1).

  However, according to the smoke test equipment using a smoke spray can, the price is high due to the use of fluorocarbon gas, and it is expected that the price will rise because it is difficult to obtain alternative fluorocarbons in the future. There is a problem that the work efficiency of the inspection is poor because the control of the amount is not easy.

  In addition, according to the smoke test equipment using incense, the strong smell makes it useless in a building where a large number of people gather, especially in a hospital, and the quantity that can be checked with one incense is limited. There is a problem that the work efficiency of the inspection is poor because there is a possibility that it will disappear on the way.

  In order to solve such a problem, in the smoke test apparatus of Patent Document 2, smoke is emitted from the tip end in a sensor cover provided via an expandable support rod to the operation part. A body is provided, and the smoke body is provided with a heater and a liquid supply unit impregnated with a water-soluble liquid in a cylinder, and when the test is performed, air is sent from the blower to the cylinder and the water-soluble liquid vaporized by heating by the heater To produce simulated smoke and test the smoke detector.

  According to such a smoke test jig, since the pseudo smoke which is atomized is generated by the vaporization of the water-soluble liquid, the oil sensor or the ceiling surface adheres with viscous oil smoke etc. In addition, it is possible to conduct an operation test of the smoke sensor while avoiding the deposition of dust and the like.

  As shown in FIG. 1, the smoke test apparatus 10 according to this embodiment includes an operation unit 12, a support rod 14 and a sensor cover 16. The operation unit 12 is formed with a spray can storage unit 32 for storing a fume spray can filled with fluorocarbon gas, and the spray can storage unit 32 is replaced with a smoke spray can and, as shown in FIG. A smoke generating device 36 having the same outer shape as the can is housed.

  The smoke spray can used for the smoke generator 36 has, for example, an outer size of 50 mm in diameter and 150 mm in height, and the smoke generator 36 has the same outer size of 50 mm in diameter and 150 mm in height as the smoke spray can. For this reason, by removing the cap 35, the smoke generation device 36 can be stored and used in the spray can storage portion 32, like the smoke spray can.

  A switch 54 is disposed on the top of the smoke generating device 36, and the switch 54 is provided with a switch lever 55. Corresponding to this, the operation unit 12 is provided with an operation lever 18 rotatable by a support shaft 20 and a link lever 34 for transmitting the movement of the operation lever 18. The switch lever 55 of the smoke generation device 36 stored in the can storage portion 32 is located.

  When the operation lever 18 of the operation unit 12 is pulled with a finger, the operation lever 18 rotates clockwise about the support shaft 20 and the link lever 34 is pushed downward, whereby the switch lever 55 is pushed and the switch 54 turns on. When the switch 54 is turned on, the smoke generation device 36 atomizes the water-soluble liquid vaporized by heating by energization of the heater to generate pseudo smoke, and discharges the pseudo smoke generated in the sensor cover 16 through the support rod 14.

  When the spray can is stored in the spray can storage portion 32, when the control lever 18 is pulled with a finger, the link lever 34 is pushed downward, whereby the pressing switch on the top of the spray can is pressed and the gas is ejected It was done. The switch lever 55 of the smoke generating device 36 operates by pushing the link lever 34 downward similarly to the spouting operation of the spray can, so that the structures of the control lever 18 and the switch lever 55 of the smoke test device do not need to be changed. is there. For this reason, the smoke generating device 36 can be used as a substitute for the spray can of the existing smoke tester.

  The support rod 14 is detachably mounted on the distal end side of the operation unit 12, and in the present embodiment, the first pipe member 22 detachably connected to the operation unit 12 and the first pipe member 22. The second pipe member 24 is inserted therein and axially slidable.

  The first pipe member 22 and the second pipe member 24 have a hollow pipe structure, and have an internal passage for releasing smoke from the opening at the tip inside, and the inner diameter of the pipe member to be the internal passage is, for example, It is 10 mm or more, and about 20 mm is desirable for practical use.

  Further, as a length of the support rod 14 by the two-step 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 drawn-out position of the second pipe member 24 drawn out of 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 lightweight material of FRP resin, and are extremely high in resistance to the test of the smoke sensor provided in high voltage electrical equipment. While guaranteeing insulation, weight reduction is achieved.

  The tip of the second pipe member 24 is a smoke outlet, and a diffusion guide 26 is attached thereto.

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

[Fuming device]
FIG. 3 is an explanatory view showing a smoke generating apparatus having the same outer shape as the smoke spray can, and showing the appearance in FIG. 3 (A) and the internal structure in FIG. 3 (B). FIG. 4 is an explanatory view showing an embodiment of the smoke generating cartridge by a cross section, and FIG. 5 is an explanatory view showing a state where the smoke generating apparatus is disassembled in order to replace the smoke generating cartridge.

(Composition of smoke generation device)
As shown in FIG. 2, the smoke generating device 36 is provided with a cylindrical case 38 having a diameter of, for example, 50 mm and a height of 150 mm, which has the same outer size as the smoke spray can. The upper case 38a and the lower case 38b which are half-divided in the longitudinal direction are separable, and are connected by a central connecting portion 38c. The lower case 38b is provided with an air vent 38d.

  Further, the material of the case 38 may be a metal case or a synthetic resin case. Further, the housing 38 is not necessarily required to have a sealed structure, and may have a frame shape that can be stored in the spray can storage portion 32 shown in FIG. 2.

  In the housing 38 of the smoke generating device 36, there is a smoke generating cartridge 60 which is removable by a rechargeable battery 42 such as a lithium ion battery, a blower pump 44 functioning as a blower, an air flow detection unit 48, a control unit 50 and a connector 56. It has been incorporated.

  The blower pump 44 uses, for example, a piezoelectric pump in order to miniaturize it. Pressurized air by the drive of the blower pump 44 is sent out through the air pipe 46 and sent to the cylindrical cases 52a and 52b. An air flow detection unit 48 and a control unit 50 mounted on a circuit board are disposed in the cylindrical case 52a. Further, in the cylindrical case 52b, a smoke cartridge 60 detachably provided to the control unit 50 by the connector 56 is accommodated.

  The pressurized air fed from the blower pump 44 through the air pipe 46 passes from the air flow detection unit 48 in the cylindrical case 52a to the periphery of the control unit 50, as indicated by the broken line, and passes through the smoke cartridge 60 of the cylindrical case 52b. The air is fed from a portion of the connector 56 and is discharged from the outlet 53 at the upper end of the cylindrical case 52b through the periphery of the smoke cartridge 60. The air flow detection unit 48 detects an air flow flowing in the cylindrical case 52 a and outputs an air flow detection signal to the control unit 50.

  A switch 54 is disposed outside the upper portion of the upper case 52 a in the housing 38, and the switch 54 operates by pressing 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 the control unit 50 is connected to the signal line 57 from the switch 54, the power supply line 43 from the battery 42, the control line 59 for the blower pump 44, and the like.

  When the control unit 50 detects the on signal of the switch 54 by the depression of the switch lever 55 via the link lever 34 by the operation of the operation lever 18 shown in FIG. Control is performed to feed a portion of the cylindrical case 52 a, 52 b from 46 into the smoke cartridge 60.

  When the control unit 50 detects an air flow from the air flow detection signal of the air flow detection unit 48 provided in the cylindrical case 52 a, the control unit 50 energizes the heater built in the smoke cartridge 60 to heat it. By vaporizing the water-soluble solution for smoke that is impregnated in the liquid supply unit incorporated in the above, it is controlled that the pseudo smoke is smoked and released from the discharge port 53 of the cylindrical case 52b.

(Fuming cartridge)
As shown in FIG. 4, in the smoke generation cartridge 60, a rod-like liquid supply portion 68 is housed inside a cylindrical body 62, and a heater 70 is wound around the liquid supply portion 68. It is connected to the connection pins 56a and 56b.

  The cylinder 62 has an inlet 64 at its lower end, and introduces the pressurized air sent from the blower pump 44 of FIG. 3 into the cylinder 62 as shown by the arrow. Further, a discharge port 66 is opened at the top of the cylindrical body 62, and the air introduced from the inflow port 64 is discharged upward.

  The liquid supply portion 68 is, for example, a rod-like fiber non-combustible filter such as glass fiber or a non-combustible filter made of a foamed resin formed in a rod shape. A hole is formed inside, and the void hole is impregnated with a predetermined water-soluble liquid to be a smoke generating agent.

  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. The electric current for heating is vaporized to cause the water-soluble liquid impregnated in the liquid supply portion 68 to vaporize, and the vaporized liquid is released from the discharge port 66 to generate atomized pseudo smoke (aerosol).

  As the water-soluble liquid to be impregnated in the liquid supply portion 68, a water-soluble liquid harmless to the human body is used which contains at least one component having hydrophilicity and high water-retention property, for example, glycerin, propylene glycol, etc. It is done.

  When a water-soluble liquid containing components such as glycerin and propylene glycol impregnated in the liquid supply portion 68 is heated and vaporized by the heater 70, 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 condenses on it to form a white smoke, whereby a simulated smoke is generated.

  In the pseudo smoke generated in this way, propylene glycol and glycerin have high hydrophilicity, take in the evaporated water, and are highly effective in preventing evaporation of the taken in water, so white smoke is relatively long. It will float in the air over time.

(Cartridge replacement)
As shown in FIG. 5, when replacing the smoke cartridge 60 which has been used, the upper case 38a is removed from the lower case 38b of the housing 38 and the lower case 38b is removed from the smoke generating apparatus 36 taken out of the smoke test apparatus. The cylindrical cases 52a and 52b stored in the lower case 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 by the connector 56, the used smoke cartridge 60 is removed, replaced with a new smoke cartridge, and replaced.

[Test work by smoke test equipment]
Next, an operation test of the smoke sensor using the smoke test apparatus 10 of the present embodiment will be described.

  As shown in FIG. 1, in order to perform the operation test of the smoke sensor 30 by the smoke test apparatus 10, the smoke cover 30 is put on the smoke sensor 30 installed on the ceiling surface, and the peripheral end of the sensor cover 16 Attach the edge to the ceiling.

  In this state, when the control lever 18 is pulled, the switch 54 provided on the smoke generation device 36 via the link lever 34 is turned on by the depression of the switch lever 55 by the rotation of the control lever 18 around the support shaft 20.

  When the switch 54 is turned on, the control unit 50 of the smoke generating apparatus 36 shown in FIG. 3 detects that the switch 54 is turned on to drive the blower pump 44, and the smoke cartridge is driven via the air pipes 46 via the cylindrical cases 52a and 52b. The pressurized air is fed to 60 and through the internal passage around the fume cartridge 60.

  The signal level of the air flow detection signal from the air flow detection unit 48 provided in the cylindrical case 52a is increased by the air flow from the air flow pump 44, and the control unit 50 causes the air flow detection signal to reach a predetermined threshold level or higher as shown in FIG. The heater 70 provided in the illustrated smoke cartridge 60 is energized and heated. As described above, since the heater 70 is not energized unless the airflow to the smoke cartridge 60 increases, abnormal heating due to the energization of the heater 70 can be prevented when there is no airflow or when the airflow is low.

  When the liquid supply unit 68 is heated by the energization of 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 pressurized air from the blower pump 44. It is atomized by being discharged from the outlet 66 and a simulated smoke is generated.

  The simulated smoke released from the smoke cartridge 60 is sent upward through the internal passage of the support rod 14 by the air flow sent from the air pump 44 through the periphery of the smoke cartridge 60 and the diffusion of the tip of the support rod 14 It is emitted from the guide 26 into the sensor cover 16.

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

  Here, when the smoke testing device 10 is used to perform the first smoke sensor operation test, the simulated smoke generated by the smoke generating device 36 of the operation unit 12 passes through the inner passage of the support rod 14 and the sensor cover It takes some time to reach the concentration at which the smoke detector 30 is triggered, being fed into the chamber 16. However, in the operation test of the second and subsequent smoke detectors, the simulated smoke generated in the previous test is stagnant in the inner passage of the support rod 14, and when the switch lever is turned on by operating the operation lever 18, the stagnation occurs. The simulated smoke being immediately delivered into the sensor cover 16 makes it possible to achieve the concentration at which the smoke detector is triggered in a short time with little time delay.

  When the smoke sensor operation test is repeated using the smoke test apparatus 10, the amount of the water-soluble liquid impregnated in the liquid supply portion 68 of the smoke cartridge 60 may be low, and the smoke amount may be reduced. is there.

  In this case, the cap 35 provided at the bottom of the operation unit 12 of the smoke test apparatus 10 is removed, the smoke generating apparatus 36 is taken out, the housing 38 is disassembled as shown in FIG. Switch to Thus, when the smoke cartridge 60 is used up, it can be easily replaced with a new one.

  When the smoke cartridge 60 has been used, the smoke generating device 36 may be replaced with an unused new one. The used smoke generation device 36 can then be reused by disassembling it as shown in FIG. 5 and replacing the smoke cartridge 60 separately.

[Embodiment without air flow detection unit]
As another embodiment of smoke generation according to the present invention, the air flow detection unit 48 provided in the smoke generation apparatus 36 of FIG. 3 may be omitted.

  In the embodiment not having the air flow detection unit 48, when the on operation of the control unit 50 and the switch 54 is detected, in addition to the drive of the blower pump 44, the electric heating of the heater 70 built in the smoke cartridge 60 is performed. .

  As described above, even if the air flow detection unit 48 is not provided, since the compressed air is sent to the smoke cartridge 60 by the drive of the air pump 44, the air flow passing through the smoke cartridge 60 is not cut off. Since there is no possibility that abnormal heating will occur, it is practically possible to operate normally without providing the air flow detection unit 48.

[Other Embodiments of Smoke Test Apparatus]
FIG. 6 is an explanatory view showing an embodiment of a smoke test apparatus in which a smoke generator is incorporated on the sensor cover side.

  As shown in FIG. 6, in the present embodiment, the smoke test unit 72 is provided at the tip of the support rod 14 provided in the operation unit 12, and the spray can storage unit formed in the smoke test unit 72. In place of the smoke spray can, a smoke generating device 36 is provided.

  As in the embodiment of FIG. 1, a sensor cover 16 having a funnel-shaped windproof cover 27 and a bellows cushion 28 is mounted on the tip side of the smoke test unit 72. The operation unit 12 and the support rod 14 are also the same as in the embodiment of FIG. 1, and the operation lever 18 provided on the operation unit 12 is not necessary for the test operation, but is left as it is.

  The proximity switch 74 is activated and turned on when the ceiling surface on which the smoke detector 30 is installed is approached 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.

  When the control unit 50 of the smoke generating apparatus 36 shown in FIG. 3 detects the on signal from the proximity switch 74, the control unit 50 drives the blower pump 44, and the level of the air flow detection signal of the air flow detection unit 48 exceeds a predetermined threshold level.
