Embodiment

[0027] As Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the device includes a cabinet 1, a mounting plate 2, and a partition plate 3. The mounting plate 2 is fixedly arranged at the upper end inside the cabinet 1. The partition plate 3 is fixedly arranged at the middle end of the top of the mounting plate 2, and the top of the partition plate 3 is fixedly connected to the inner wall of the cabinet 1. An exhaust assembly 4 is arranged on the outer wall of the partition plate 3. A monitoring assembly 5 is arranged inside the cabinet 1. The exhaust assembly 4 includes an exhaust fan 401 fixedly arranged on the right side of the bottom of the partition plate 3. An air inlet hole 402 is integrally arranged on the right side inside the partition plate 3. A first mounting hole 403 is integrally arranged at the upper right end inside the cabinet 1. The monitoring assembly 5 includes an early fire warning detection device 501 fixedly arranged on the left side of the bottom of the partition plate 3. A composite fire detection device 502 is fixedly arranged on the left side of the bottom of the partition plate 3. A second mounting hole 503 is integrally arranged at the upper left end inside the cabinet 1. An exhaust hole 504 is integrally arranged on the left side inside the partition plate 3. Non-pressurized perfluorinated hexanone fire extinguishing devices 505 are fixedly arranged on the left and right sides in the middle of the cabinet 1.

[0028] The model of the early fire warning detection device 501 is ZX-D-YT, and the objects it detects are smoke particles and temperature inside the cabinet 1. The model of the composite fire detection device 502 is ZX-D-FT, and the objects it detects are temperature, carbon monoxide concentration, and smoke concentration inside the cabinet 1. A cabinet door 6 is arranged on the front left side of the outside of the cabinet 1 through hinges and on the right side through a lock. A controller 7 is fixedly arranged on the front end of the outside of the cabinet door 6.

[0029] The staff first connect the controller 7 to the electrical control console of the prior art in a wireless or wired manner, then input the values to be monitored by the very early fire warning detection device 501 and the composite fire detection device 502 into the controller 7, and then turn on the exhaust fan 401. The exhaust fan 401 discharges the outside air into the cabinet 1 through the intake hole 402 from the first installation hole 403, so as to discharge the heat generated by the electronic components inside the cabinet 1 through the exhaust hole 504 and the second installation hole 503. Through the above method, heat dissipation treatment is carried out inside the cabinet 1. In addition, the very early fire warning detection device 501 monitors the pyrolysis particle concentration inside the cabinet 1 in real time. When the concentration exceeds the value set by the controller 7, the controller 7 transmits a signal to the electrical control console, and the electrical control set alarms to remind the staff to check the circuit inside the cabinet 1 and eliminate potential hazards. The composite fire detection device 502 monitors the smoke, carbon monoxide and temperature parameters inside the cabinet 1 in real time. When any two of the three parameters reach the values set by the controller 7, a fire occurs. The controller 7 transmits a signal to the electrical control console. The staff can immediately rush to the scene for fire extinguishing through the alarm area displayed on the electrical control console. At the same time, the non-pressurized perfluoromethylcyclohexanone fire extinguishing device 505 is turned on. Perfluoromethylcyclohexanone has a low boiling point (49°C). Once released at the fire scene, it will quickly evaporate and absorb heat. During the evaporation process, perfluoromethylcyclohexanone changes from a liquid state to a gaseous state, absorbing a large amount of heat energy, thereby causing the temperature around the fire source to decrease and extending the time for the staff to rush to the fire scene. Embodiment

[0030] As Figure 2 、 Figure 5 shown, a filter screen 8 is fixedly arranged inside the first installation hole 403, a check valve 9 is fixedly arranged inside the second installation hole 503. The diameters of the first installation hole 403 and the second installation hole 503 are the same, and the axes of the first installation hole 403 and the second installation hole 503 are coaxially designed. A rotating rod 10 is rotatably connected inside the partition plate 3. The axis of the rotating rod 10 is coaxially designed with the axes of the first installation hole 403 and the second installation hole 503. Connecting sleeves 11 are sleeved on the left and right sides of the outside of the rotating rod 10 with threads. The sealing plates 12 fixedly arranged on the outer sides of the connecting sleeves 11 are slidably connected to the top end inside the cabinet 1. A worm gear 13 is fixedly sleeved on the left side of the outside of the rotating rod 10. The left connecting sleeve 11 is designed to be connected to the rotating rod 10 with a left-handed thread, and the right connecting sleeve 11 is designed to be connected to the rotating rod 10 with a right-handed thread. A motor 14 is fixedly arranged on the top of the cabinet 1, and the motor 14 is a stepper motor. The motor 14 stops running after rotating 10 circles. The worm 15 fixedly arranged at the bottom of the motor 14 rotates through the top of the cabinet 1. The worm 15 is designed to be meshed with the worm gear 13 with teeth.

[0031] The filter screen 8 can filter the dust in the external gas discharged into the interior of the cabinet body 1. The one-way valve 9 can prevent the external gas from being discharged into the interior of the cabinet body 1 through the second mounting hole 503. When the composite fire detection device 502 is activated, the motor 14 is turned on. The motor 14 drives the worm 15 to drive the worm wheel 13 and the rotating rod 10 to rotate. Through the threaded transmission between the rotating rod 10 and the connecting sleeve 11, the connecting sleeve 11 drives the blocking plate 12 to move along the direction of the first mounting hole 403 and the second mounting hole 503. When the motor 14 rotates ten circles, the blocking plate 12 stops moving. The blocking plate 12 fits against the inner wall of the cabinet body 1, that is, the blocking plate 12 blocks the first mounting hole 403 and the second mounting hole 503, thereby isolating the interior of the cabinet body 1 from the outside world. This not only reduces the oxygen content inside the cabinet body 1, but also prevents the perfluorinated hexanone from being discharged from the interior of the cabinet body 1, ensuring the fire extinguishing effect of the non-pressurized perfluorinated hexanone fire extinguishing device 505.
