Description

Technical Field

[0001] This application relates to the field of alarm testing technology, and more specifically, to an automatic testing device for fire manual alarm buttons. Background Technology

[0002] Manual fire alarm buttons are an important component of automatic fire alarm systems, used to manually trigger alarm signals in the event of a fire. To ensure the sensitivity of manual fire alarm buttons, both non-operation and operation tests are required. The non-operation test primarily checks that the manual fire alarm button will not falsely trigger an alarm signal under normal conditions. The operation test checks whether the manual fire alarm button can correctly emit an alarm signal when manually triggered and whether it puts the automatic fire alarm system into the corresponding alarm state.

[0003] A search revealed that Chinese patent CN220490345U discloses a test device for the action performance of a manual fire alarm button. This device uses a motor to control the support plate supporting the copper ball, ensuring that the brass ball swings freely and falls from a fixed position. This solves the problem of applying an initial force to the copper ball when manually releasing it, reducing test errors and making the test results more accurate.

[0004] While the aforementioned devices can detect whether alarm buttons are activated or not, they lack a reset function, requiring manual resetting. This results in low automation and inefficient detection. Therefore, we propose an automatic detection device for manual fire alarm buttons. Utility Model Content

[0026] The technical solution of this application will now be clearly and completely described in conjunction with the accompanying drawings.

[0027] Please see Figure 1 and Figure 2This application provides an automatic detection device for a fire manual alarm button, including a support frame 1. The lower part of the support frame 1 is provided with a detection channel. An elastic element 2 and a counterweight 3 are arranged sequentially along the length of the detection channel. The elastic element 2 and the counterweight 3 are both vertically slidably mounted on the support frame 1. A power supply pin 4 is provided below the elastic element 2 and the counterweight 3. The power supply pin 4 is vertically slidably mounted below the support frame 1. A reset cylinder 5 is fixedly mounted on the side of the support frame 1. A reset bracket 501 is fixedly mounted on the telescopic end of the reset cylinder 5. A reset plug 502 is rotatably connected to the reset bracket 501. A first through slot 101 is opened on the side of the support frame 1 for the reset plug 502 to be inserted into the detection channel. A telescopic motor 503 is rotatably connected to the reset bracket 501. A connecting rod 504 is rotatably connected to the telescopic end of the telescopic motor 503. The connecting rod 504 is connected and fixed to the reset plug 502.

[0028] By placing the manual alarm button in the detection channel and moving it below the elastic element 2, the power supply pin 4 is controlled to rise and contact the test pad on the back of the manual alarm button to supply power to the manual alarm button; the elastic element 2 is controlled to move downward and press the panel of the manual alarm button, and the production detection software starts to perform a non-operation function test. After the test, the test results are recorded and sent to the central control.

[0029] After the non-action test is completed, the elastic element 2 is reset and the reset cylinder 5 is extended so that the reset plug 502 can be inserted into the reset hole of the manual alarm button. Then, by controlling the extension motor 503 to extend, the connecting rod 504 pushes the reset plug 502 to rotate, thereby resetting the manual alarm button.

[0030] After the reset is completed, control the power supply pin 4 to reset and move the manual alarm button to below the counterweight 3; first control the power supply pin 4 to supply power to the manual alarm button, then control the counterweight 3 to release, so that the counterweight 3 can hit the panel of the manual alarm button. The production detection software starts to perform the action test, records the test results after the test and sends them to the main control.

[0031] After the action test is completed, control the counterweight 3 to reset and repeat the reset operation of the manual alarm button.

[0032] like Figure 3 As shown, a limiting panel 6 is provided in the detection channel. The limiting panel 6 is vertically slidably mounted on the support frame 1. The limiting panel 6 has clearance grooves 601 on both sides for the elastic element 2 and the counterweight 3 to pass through. A second pressing cylinder 602 is fixedly installed on the support frame 1. The telescopic end of the second pressing cylinder 602 is connected and fixed to the limiting panel 6. The upper part of the manual alarm button can be limited by the limiting panel 6. When the power supply pin 4 moves upward, the stability of the connection between the power supply pin 4 and the test pad on the back of the manual alarm button can be ensured.

[0033] Preferably, a support plate 7 is fixedly installed at the lower part of the detection channel. The support plate 7 has a second through slot for the power supply pin 4 to pass through. A power supply cylinder 401 is fixedly installed below the detection channel, and the power supply pin 4 is fixedly installed at the telescopic end of the power supply cylinder 401. By supporting the manual alarm button placed in the detection channel with the support plate 7, and by using the conveyor belt on the surface of the support plate 7 to transport the manual alarm button, automated detection is achieved.

[0034] like Figure 4 like Figure 5 As shown, a first pressing cylinder 201 is installed on the support frame 1. The telescopic end of the first pressing cylinder 201 is connected and fixed to one end of the elastic element 2 through a spring fixing base. A lifting cylinder 301 is fixedly installed on the support frame 1. The telescopic end of the lifting cylinder 301 is connected and fixed to the counterweight 3.

[0035] Preferably, two elastic elements 2 and two counterweights 3 are arranged side by side along the width of the detection channel, and reset cylinders 5 are installed on both sides of the support frame 1 to increase the detection efficiency of the device.
