After the bottom support plate 77 moves to the bottom of the filter plate 74, the bottom support plate 77 and the top pressure strip 73 cooperate to achieve the effect of clamping the filter plate 74.

[0055] In the actual operation process, firstly, the device is powered on. When the cabinet 2 is working, the temperature sensor 5 can detect the temperature inside the cabinet 2. In order to effectively detect the temperature of different positions of the cabinet 2, the temperature of different areas of the inner wall of the cabinet 2 can be transmitted to the heat conducting plate 4. The temperature sensor 5 detects the temperature of the heat conducting plate 4 to know the overall temperature inside the cabinet 2. Once the temperature is abnormal, the lamp body 62 starts to flash to give a light alarm. At this time, the second motor 68 works and drives the round rod to rotate. The round rod drives the knocking plate 69 to rotate. After the knocking plate 69 rotates, it knocks the impact plate 65. After being knocked, the impact plate 65 hits the force plate 66, and a sound is emitted after the collision. Through the above sound and light alarm method, outsiders can be quickly warned, so that the staff can quickly deal with it and avoid the occurrence of dangerous situations. The mesh frame 61 can provide protection for the knocking plate 69 and other components to avoid interference with the knocking work.

[0056] The dry powder storage frame 31 in the device stores dry powder fire extinguishing agent for fire extinguishing. In normal operation, the two ends of the rope 34 are respectively wound between the moving block 33 and the side wall of the horizontal plate 32, and the rope 34 pulls the moving block 33. At this time, the baffle 36 remains inserted into the dry powder storage frame 31, thereby blocking the bottom opening position of the dry powder storage frame 31 to achieve a sealing effect. Once a fire occurs inside the distribution cabinet, the rope 34 will burn out as the temperature rises, and the rope 34 After the break, the first spring 35 pulls the moving block 33 to quickly move away from the dry powder storage frame 31. After the moving block 33 moves, the inclined rod 391 flips over. At this time, the inclined rod 391 pulls the plug plate 38, causing the plug plate 38 to leave the baffle 36. The baffle 36 moves under the elastic force of the second spring 37 and gives up covering the bottom opening of the dry powder storage frame 31, causing the dry powder fire extinguishing agent inside the dry powder storage frame 31 to fall downward, thereby achieving the function of extinguishing the fire.

[0057] After the dry powder fire extinguishing agent falls downward, it will fall into the grille plate 394 and be scattered after passing through the gaps on the grille plate 394, so as to achieve the purpose of dispersing and falling. At the same time, the first motor 398 works and drives the threaded adjustment rod 399 to rotate, the threaded adjustment rod 399 drives the second rectangular plate 397 to move, and the second rectangular plate 397 drives the frame plate 393 to move inside the cabinet 2, so that the dry powder fire extinguishing agent falls in different areas. During the movement of the frame plate 393, the electric push rod 383 pushes the movable plate 381, and the movable plate 381 drives the rack 382 to move, and the rack 382 drives the gear 395 to rotate, and the gear 395 drives the connected shaft to rotate, and the shaft drives the grille plate 394 to flip and swing. During the swinging process, the dry powder fire extinguishing agent staying thereon can be caused to fall quickly during the rolling process, and at the same time, the purpose of uniform falling is further achieved. The dry powder fire extinguishing agent after falling can extinguish the possible fire, and the fire extinguishing effect is better.

[0058] The cabinet 2 dissipates heat through the heat dissipation vents 72, and the filter plate 74 inside the trapezoidal frame 71 can prevent external dust from entering the cabinet 2. At the same time, the filter plate 74 is arranged inside the trapezoidal frame 71 to prevent the heat dissipation vents 72 from being directly arranged outside and causing external rainwater to invade. The filter plate 74 is easy to load and unload. Only by rotating the two-way threaded rod 76, the two-way threaded rod 76 drives the two bottom supporting plates 77 to move towards or away from each other. When the bottom supporting plate 77 moves to leave the bottom of the filter plate 74, the filter plate 74 falls out downward, and the purpose of disassembly is achieved. Similarly, during installation, the filter plate 74 is placed into the trapezoidal frame 71 from bottom to top, so that the top of the filter plate 74 is fitted to the bottom of the top pressure strip 73, and then the two bottom supporting plates 77 are controlled to move to fit the bottom of the filter plate 74, that is, the installation is achieved. The convenient loading and unloading function is more conducive to the user to replace or clean the filter plate 74.
