Description
Technical Field
[0001] This utility model relates to the field of equipment testing technology, specifically to a fire alarm detection device that is easy to disassemble. Background Technology
[0002] Electrical cabinets, as crucial equipment for power distribution and control, are widely used in various locations such as factories, shopping malls, office buildings, and hotels in modern industrial, commercial, and civil buildings. However, fires caused by electrical faults within these cabinets are frequent, resulting in significant losses for businesses and society. Traditional smoke detectors and temperature detectors primarily trigger alarms when significant smoke or high temperatures are generated. However, in the early stages of electrical fires, often only the wires and protective electrical connections are decomposing due to heat, before large amounts of smoke or high temperatures are produced. Traditional detectors cannot detect these potential fire hazards in time, thus delaying optimal response.
[0003] Currently, early detection devices are typically fixed to the cabinet with screws during installation. If the device malfunctions during long-term use and needs to be removed, the screws are prone to wear and tear during repeated disassembly and removal, resulting in poor stability. When installed near electrical appliances, they can generate vibrations, which can damage internal components such as chips over time. This prevents the device from promptly alerting staff, accurately identifying early signs, stages of fire, and potential threats, thus compromising safety. Utility Model Content

A U-shaped opening 38 is opened on the part of the sliding plate 17 that protrudes from the detection body 12.
[0030] Specifically, the detector body 12 is installed by the cooperation between the baffle 13 and the long plate 14. Then, the sliding block 19 inside the detector body 12 is engaged with the limiting port 15 on the mounting plate 10. The sliding long plate 17 is pushed into the T-shaped slot 16. Then, the sliding block 19 and the limiting plate 20 slide down together until the sliding block 19 slides into the limiting port 15. At this time, the sliding long plate 17 and the limiting block 18 abut against each other. The U-shaped opening 38 on the outside of the outer body 12 of the sliding long plate 17 is engaged with the limiting rod 37. The limiting rod 37 is stuck in the U-shaped opening 38 to prevent the sliding long plate 17 from sliding out of the T-shaped slot 16, thereby fixing the detector body 12.
[0031] The monitoring component includes a mounting housing 24 disposed inside the detection body 12. A filter plate 25 is disposed inside the mounting housing 24. A connecting pipe 26 is connected to one side of the mounting housing 24, and the other end of the connecting pipe 26 is connected to a smoke detector 27. A sensor 28 is disposed at one end of the smoke detector 27, and a light source emitter 29 is disposed at the other side of the sensor 28.

After the sliding block 19 inside the detection body 12 cooperates with the limiting hole 15 opened on the mounting plate 10, a large force is used to push the sliding long plate 17 into the T-shaped groove 16. Then, the sliding block 19 and the limiting plate 20 slide down together until the sliding block 19 slides into the limiting hole 15. At this time, the sliding long plate 17 and the limiting block 18 abut against each other. The U-shaped opening 38 on the outside of the outer body 12 of the sliding long plate 17 cooperates with the limiting rod 37. The limiting rod 37 is stuck in the U-shaped opening 38 to prevent the sliding long plate 17 from sliding out of the T-shaped groove 16, thereby fixing the detection body 12.
[0037] During monitoring, the gas inside the cabinet enters the detector body 12 through the air inlet 39. After initial filtration by the filter plate 25, it passes through the connecting pipe 26, smoke detector 27, sensor 28, and other structures. The light source emitter 29 emits laser light into the gas, and the particle detector 30 receives the light signal. The light signal is then converted into an electrical signal by the detector plate 31 and analyzed to determine the concentration and size of the particles. Finally, the data is displayed on the display screen 32. Based on the concentration and size of the particles, it can be determined whether there is overheating inside the cabinet. If overheating occurs, the alarm light 33 next to the display screen 32 will flash red to remind staff to take timely action. This system can accurately identify early signs, development stages, and potential threats of fire, greatly enhancing safety assurance capabilities.
