Description

Technical Field

[0001] This application relates to the field of testing apparatus, and in particular to a smoke detector testing apparatus with a temperature detection module. Background Technology

[0002] As a core component of fire protection systems, the reliability of smoke and heat detectors directly affects the timeliness and accuracy of fire warnings. Currently, the detectors on the market mainly include photoelectric, ionization, and bimetallic strip types, and their functionality is generally verified through periodic manual testing or by simulating smoke and temperature environments.

[0003] The current testing setup mainly consists of a testing platform and a testing base. The testing base is located on the testing platform and is used to store the detector to be tested. A cover is placed on the testing base and covers the detector, making the space between the cover and the testing base a simulated space for the detector to operate. The tester then introduces heated flue gas into the cover to simulate the actual working scenario of the detector.

[0004] In actual use, after a long period of use, gaps may easily form between the cover and the testing platform, which reduces the realism of the simulated scenario and thus reduces the testing accuracy of the testing device. Therefore, this needs to be improved. Utility Model Content

[0005] To address the aforementioned issues, this application provides a smoke detector testing device with a temperature detection module.

[0006] This application provides a smoke detector testing device with a temperature detection module, which adopts the following technical solution:

[0007] A smoke detector testing device with a temperature detection module includes a movable frame, a storage seat for placing the detector on the movable frame, a cover on the storage seat, a simulation component that cooperates with the detector on the movable frame, the simulation component being connected to the cover, and a limiting component for limiting the cover on the storage seat.

[0008] By adopting the above technical solution, the limiting component limits the cover, making it less likely for gaps to appear between the cover and the storage base, so that the simulation component can more stably simulate the use scenario of the detector, thereby improving the testing accuracy of the testing device.

[0009] Preferably, the limiting component includes a support, a moving rod, and a limiting plate. The support is disposed on the storage base, the moving rod is slidably connected to the support in the vertical direction, the limiting plate is disposed on the moving rod, the limiting plate abuts against the cover, a mating plate is provided at one end of the moving plate away from the limiting plate, and a spring is provided on the moving rod, one end of the spring abuts against the mating plate and the other end abuts against the support.

[0010] By adopting the above technical solution, after the cover is placed on the storage seat, the worker pulls the limiting plate. The limiting plate then moves the moving rod and the mating plate in sequence, compressing the spring. The worker then releases the limiting plate, and under the action of the spring's rebound force, the limiting plate presses against the cover to limit its position, reducing the possibility of gaps between the cover and the storage seat.

[0011] Preferably, the inner wall of the cover is provided with a plurality of heating elements.

[0012] Preferably, the inner wall of the housing is provided with a heat insulation pad.

[0013] By adopting the above technical solution, the heat insulation pad makes it difficult for the temperature in the casing to be lost, thus improving the realism of the simulation component.

[0014] Preferably, the simulation component includes a smoke generator, a first fan, and a simulation tube. The smoke generator is mounted on a movable frame, and the first fan is mounted on the movable frame. One end of the first fan is connected to the smoke generator via a connecting pipe, and the other end is connected to the simulation tube. The end of the simulation tube away from the first fan is connected to a housing.

[0015] Preferably, the storage base is provided with a clamping assembly for fixing the detector. The clamping assembly includes a bracket and a clamping plate. The bracket is disposed in the storage base, and the clamping plate is rotatably connected to the bracket. A torsion spring is wound around the rotating shaft of the clamping plate.

[0016] By adopting the above technical solution, after the inspector places the detector into the storage seat, the inspector presses the clamping plate against the detector. Under the action of the torsion spring's rebound force, the detector is limited, reducing the possibility of the detector moving during the inspection process.

[0017] Preferably, the mobile frame is equipped with a purification box, which contains several filter cloths. The purification box is connected to the storage seat through an exhaust pipe, and an exhaust pipe is connected to the purification box.

[0018] By adopting the above technical solution, the filter cloth makes it less likely for the smoke discharged from the enclosure to have an impact on the surrounding environment.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. By setting a limiting component, the limiting component limits the cover, reducing the possibility of gaps between the cover and the storage base, so that the simulation component can work more stably, thereby improving the testing accuracy of the testing device;

[0021] 2. By setting up a heat insulation pad, the heat insulation pad prevents the temperature in the space between the cover and the storage base from escaping, so that the simulation component can more accurately simulate the detector's operating environment, thereby further improving the testing accuracy of the testing device;

[0022] 3. By setting up a clamping component, the detector is limited, reducing the possibility of the detector moving during the detection process. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0026] This application discloses a smoke detector testing device with a temperature detection module. (Refer to...) Figure 1 A smoke detector testing device with a temperature detection module includes a movable frame 1, on which a storage seat 2 for placing the detector is fixed. A cover 3 is provided on the storage seat 2, and a limiting component 5 for limiting the cover 3 is provided on the movable frame 1.

[0027] Reference Figure 1 The limiting assembly 5 includes a support 51, a moving rod 52, and a limiting plate 53. The support 51 is mounted on the storage base 2, and the moving rod 52 is slidably connected to the support 51 in the vertical direction. The limiting plate 53 is mounted on the moving rod 52 and abuts against the cover 3. A mating plate 54 is fixed to the end of the moving plate away from the limiting plate 53. A spring 55 is provided on the moving rod 52, with one end of the spring abutting against the mating plate 54 and the other end abutting against the support 51.

[0028] When the housing 3 is needed, the inspector places the detector into the storage seat 2, and then places the housing 3 on the storage seat 2. The inspector then pulls the limiting plate 53, which in turn moves the moving rod 52 and the mating plate 54. The mating plate 54 moves the spring 55, compressing it. After the housing 3 is in place, the inspector releases the limiting plate 53. Under the rebound force of the spring 55, the limiting plate 53 and the moving rod 52 automatically reset, making the limiting plate 53 abut against the housing 3. This reduces the possibility of gaps between the limiting plate 53 and the housing 3, allowing the simulation component 4 to work more stably, thereby improving the testing accuracy of the testing device.

[0029] Reference Figure 1 A sealing gasket 31 is provided on the side of the cover 3 near the storage base 2, and the sealing gasket 31 abuts against the storage base 2. The sealing gasket 31 is made of rubber, which has good sealing performance, further reducing the possibility of gaps between the cover 3 and the storage base 2.

[0030] Reference Figure 1 The storage base 2 is provided with a clamping assembly 6 for fixing the detector. The clamping assembly 6 includes a bracket 61 and a clamping plate 62. The bracket 61 is disposed in the storage base 2, and the clamping plate 62 is rotatably connected to the bracket 61. A torsion spring 63 is wound around the rotating shaft of the clamping plate 62.

[0031] After the inspector places the detector into the storage seat 2, the inspector presses the clamping plate 62 against the detector. Under the action of the torsion spring 63, the detector is limited, reducing the possibility of the detector moving during the inspection process.

[0032] Reference Figure 1 The simulation component 4 includes a smoke generator 41, a first fan 42, and a simulation tube 43. The smoke generator 41 is mounted on the movable frame 1, and the first fan 42 is mounted on the movable frame 1. One end of the first fan 42 is connected to the smoke generator 41 through a connecting pipe 44, and the other end is connected to the simulation tube 43. The end of the simulation tube 43 away from the first fan 42 is connected to the cover 3.

[0033] Furthermore, the inner wall of the casing 3 is provided with several heating elements 32, and the inner wall of the casing 3 is provided with a heat insulation pad 33. The heat insulation pad 33 is made of silicone, which has good heat insulation properties and reduces the possibility of temperature loss inside the casing 3.

[0034] Smoke generator 41 is activated, and first fan 42 draws in smoke, which then enters housing 3 sequentially through connecting pipe 44 and simulation pipe 43. Simultaneously, heating element 32 is activated to work with the smoke, simulating the actual working environment of the detector, thereby improving the realism and stability of the testing device during testing.

[0035] Reference Figure 1 The mobile frame 1 is equipped with a purification box 11, which contains several filter cloths 111. The purification box 11 is connected to the storage base 2 via an exhaust pipe 112, and an exhaust pipe 113 is connected to the purification box 11. A second fan 114 is also installed on the purification box 11, with one end connected to the exhaust pipe 112 and the other end connected to the purification box 11. The filter cloths 111 are made of activated carbon, which has good adsorption properties, making it less likely for the emitted smoke to affect the surrounding environment.

[0036] Reference Figure 1 The four corners of the mobile frame 1 are equipped with casters 115, which facilitate the movement of the testing device to the set position.

[0037] Reference Figure 1 The simulation pipe 43 is connected to a first solenoid valve 431, and the exhaust pipe 112 is connected to a second solenoid valve 7. During the detection process, the second solenoid valve 7 is in the closed state, and the first solenoid valve 431 is in the open state. During the exhaust process, the first solenoid valve 431 is in the closed state, and the second solenoid valve 7 is in the open state.

[0038] The implementation principle of this application embodiment is as follows: the limiting component 5 limits the cover 3, so that there is less chance of gaps between the cover 3 and the storage seat 2, so that the simulation component 4 can more stably simulate the use scenario of the detector, thereby improving the testing accuracy of the testing device.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
