In a humid environment, a large amount of external humid air easily floods into the interior of the switch cabinet, causing water droplets to condense on the surface of electrical components and triggering electrical short-circuit faults. In terms of heat dissipation, there is a lack of an effective temperature regulation mechanism, and the temperature inside the switch cabinet will rise rapidly. There are often situations where electrical components are damaged due to excessive temperature inside the switch cabinet, resulting in a significant decline in the performance of electrical components inside the cabinet body and seriously affecting the normal operation of the equipment.

[0043] Working principle and usage process of the present invention: When the environmental humidity is appropriate and moisture-proof is not required, the moisture-proof motor 38 does not work, the worm gear 36 and the worm 37 are in a static state, and the moisture-proof louver 33 remains open at a certain angle to ensure ventilation. When the humidity inside the high and low voltage switch cabinet 1 increases, the environmental sensor 39 detects the temperature change and transmits the signal to the cooling fan 311 and the moisture-proof motor 38 through the controller A. By starting the moisture-proof motor 38, the worm 37 can be driven to rotate, and the worm gear 36 meshing with the worm 37 rotates accordingly, and then drives the rotating shaft 32 fixed with the worm gear 36 to rotate synchronously. Since the swing rods 34 at one end of multiple groups of rotating shafts 32 are hinged with a connecting frame 35, when one group of rotating shafts 32 rotates, the other rotating shafts 32 are driven to rotate synchronously through the connecting frame 35, so that the moisture-proof louvers 33 fixed on the surface of the rotating shafts 32 rotate, and then the flipping angles of multiple groups of moisture-proof louvers 33 are adjusted, so that multiple groups of moisture-proof louvers 33 can be fully unfolded to expand the ventilation channel. Then, by starting the cooling fan 311, the outside cold air can enter the inside of the high and low voltage switch cabinet 1 from the ventilation channel to form air convection, reducing the temperature inside the high and low voltage switch cabinet 1. When the humidity inside the high and low voltage switch cabinet 1 is high and moisture-proof is required, the environmental sensor 39 detects the humidity change and only transmits the signal to the moisture-proof motor 38. The moisture-proof motor 38 starts, and then drives multiple groups of moisture-proof louvers 33 inside the moisture-proof frame 31 to rotate, so that multiple groups of moisture-proof louvers 33 are connected end to end, completely closed and block the inside of the moisture-proof frame 31, preventing the outside humid air from entering the inside of the high and low voltage switch cabinet 1, playing a moisture-proof role. It can accurately judge the working environment state of the high and low voltage switch cabinet 1. When the humidity or temperature is abnormal, it can automatically and accurately control the opening and closing of the ventilation channel without manual intervention, realizing accurate judgment of whether the high and low voltage switch cabinet 1 needs moisture-proof or enhanced ventilation and heat dissipation. Thus, it effectively blocks the entry of outside humid air, prevents problems such as electrical short circuits and corrosion caused by moisture, and can effectively reduce the internal temperature, avoiding the decline of electrical component performance, shortening of service life or even damage caused by high temperature, improving the stability and reliability of the switch cabinet operation, ensuring that the high and low voltage switch cabinet 1 is always in a suitable operating environment, and improving the working performance and stability of the equipment.

[0044] Furthermore, with the startup of the cooling fan 311, the drive shaft 312 at its output end can be driven to rotate synchronously. Then, driven by the transmission belt 313, the transmission shaft 314 can be driven to rotate. The bevel gear pair 315 at one end of the transmission shaft 314 transmits power to the reciprocating lead screw 316, causing the reciprocating lead screw 316 to rotate inside the heat dissipation frame 310. Furthermore, it drives the threaded block 317 and the cleaning brush holder 318 to perform a reciprocating linear motion along the surface of the positioning slide rod 319 under the restriction of the positioning slide rod 319, so that the cleaning brush holder 318 performs a reciprocating cleaning motion on the surface of the dust removal filter 320. The bristles of the cleaning brush holder 318 clean the surface of the dust removal filter 320, preventing dust from accumulating on the dust removal filter 320 and affecting the ventilation and heat dissipation effect. It can ensure that the outside cold air smoothly enters the high and low voltage switch cabinet 1, forms an efficient convection with the internal hot air, maintains a good heat dissipation effect, ensures the stable operation of electrical components at an appropriate temperature, reduces the risk of failures caused by overheating. The cleaning brush holder 318 automatically cleans the dust removal filter 320, eliminating the need for manual frequent disassembly and cleaning of the dust removal filter 320, saving labor costs and maintenance time, reducing the risk of equipment damage caused by manual operation, and also avoiding the decline in equipment performance due to untimely maintenance. Without the need for an additional power source, the cleaning function of the dust removal filter 320 is achieved without increasing energy consumption, improving the energy utilization efficiency, and conforming to the development concept of energy conservation and environmental protection.

[0045] It should be noted that when the outside air enters the high and low voltage switch cabinet 1, it first passes through the drying filter 321. The drying filter 321 adsorbs the moisture in the air, further reducing the humidity of the air entering the high and low voltage switch cabinet 1. Then it passes through the dust removal filter 320. The dust removal filter 320 filters the dust particles in the air, purifying the air entering the high and low voltage switch cabinet 1 and providing a clean and dry operating environment for the electrical components inside the high and low voltage switch cabinet 1.

[0046] Furthermore, when a fire breaks out inside the high- and low-voltage switch cabinet body 1, the flame sensor 43 captures the flame signal and transmits the signal to the lead screw slide 41, the lead screw slide 42, the electric telescopic rod 45, the swing motor 414, and the electromagnet 518 through the controller B. After receiving the fire signal, the lead screw slide 41 and the lead screw slide 42 are activated. By adjusting the position of the moving end, the flame sensor 43 and the fire extinguishing frame 44 are aligned with the fire source position, ensuring that the fire extinguishing device can accurately act on the ignition point, which helps the fire extinguishing device to quickly act on the ignition point, avoid blind fire extinguishing, improve the success rate of initial fire extinguishing, and reduce fire losses. Subsequently, the electric telescopic rod 45 extends, and its output end pushes the articulated rod 46 to rotate around the articulation point. The other end of the articulated rod 46 drives the extrusion rod 47 to move downward. The pressing seat 48 at the bottom end of the extrusion rod 47 presses the handle 410 at the top of the fire extinguisher 49, causing the fire extinguisher 49 to eject the fire extinguishing agent, which is sprayed to the fire source through the nozzle 411, realizing the automatic spraying of the fire extinguishing agent by the fire extinguisher 49 without manual operation of the fire extinguisher 49. The response speed is fast, and fire extinguishing operations can be quickly launched in the initial stage of the fire, effectively curbing the spread of the fire. At the same time, the swing motor 414 is activated, and the eccentric rod 415 at its output end rotates, driving the swing column 416 and the articulated frame 417 to perform a circular swinging motion inside the fixed frame 413. As a result, the swing sleeve 412 fixed on the surface of the swing column 416 moves synchronously, further driving the nozzle 411 to change the spraying orientation, expanding the fire extinguishing range, and improving the fire extinguishing effect. It can automatically adjust the positions of the fire extinguisher 49 and the nozzle 411 at the time of the fire, accurately act on the ignition point, and at the same time automatically spray the fire extinguishing agent. It can quickly launch fire extinguishing operations in the initial stage of the fire, effectively curb the spread of the fire, and the fire extinguishing agent is no longer limited to spraying in a single direction, but is sprayed in all directions, covering a larger area, improving the fire extinguishing effect, ensuring that fires in different directions and ranges can be extinguished, reducing the possibility of re-ignition, realizing intelligent automatic control, without manual operation, not only improving the fire extinguishing response speed, but also avoiding the safety risks that may be brought by manual operation in a dangerous environment. The intelligent automatic control also improves the reliability and stability of the fire extinguishing system and reduces the mistakes caused by human factors.

[0047] Furthermore, in the normal working state, the power - receiving female terminal 52 and the power - receiving male terminal 53 are connected, and the high - and - low - voltage switchgear is powered through the power - receiving cable 54. At this time, the electromagnet 518 is not energized. Under the action of the second spring 520, the armature 519 makes the locking rod 521 insert into the locking groove of the locking block 516, the rotating shaft 515 is locked, the rack 513 cannot move, and components such as the push - pull rod 55 and the extrusion push rod 56 remain stationary. The power - receiving female terminal 52 and the power - receiving male terminal 53 are stably connected, avoiding power transmission failures caused by loosening, ensuring the continuous and stable operation of the high - and - low - voltage switchgear. When the flame sensor 43 detects a fire signal and transmits it to the electromagnet 518 through the controller B, the electromagnet 518 is energized to generate magnetic force, attracting the armature 519 to slide towards the electromagnet 518 against the elastic force of the second spring 520, causing the locking rod 521 to disengage from the locking groove of the locking block 516, releasing the lock on the rotating shaft 515. Then, under the action of the first spring 510, it can quickly push the extrusion push rod 56 to move around one end of the support rod 57, thereby driving the push - pull rod 55 and the pressure - receiving rod 58 to move. Then, with the cooperation of the pressure - receiving bow 512, it can push the fixed rack 513 to slide on the surface of the support frame 511, driving the meshing gear 514 to rotate, making the rotating shaft 515 drive the locking block 516 to rotate accordingly, completely disengaging it from the position where the trigger seat 517 and the locking rod 521 are located. By the push - pull rod 55 sliding in the push - pull groove inside the power - off seat 51, the power - receiving male terminal 53 is separated from the power - receiving female terminal 52, realizing automatic power - off, preventing electrical accidents caused by fire, reducing the risk of fire spread and personnel electric shock, comprehensively protecting the safety of equipment and personnel, and winning precious time for subsequent fire - fighting and safety protection. It can effectively contain the further spread of the fire due to electrical factors, reduce the losses and hazards caused by the fire, greatly improve the safety of the high - and - low - voltage switch cabinet body 1 in case of fire, not only improve the success rate of fire - fighting, but also reduce the damage to equipment and personnel caused by the fire, providing a strong guarantee for the safe operation of the entire power facility.

[0048] It should be noted that: before the high and low voltage switch cabinet body 1 is used, the operator manually squeezes and pushes the power connection end 53 towards the power connection mother end 52, so that the power connection mother end 52 and the power connection end 53 are connected. During the movement of the power connection end 53, the push-pull rod 55 can be driven to slide in the push-pull groove opened inside the power-off seat 51, thereby driving the extrusion push rod 56 to compress the first spring 510. At the same time, the pressure rod 58 and the pressure bow 512 will move accordingly, and then push the rack 513 to move inside the support frame 511, so that the gear 514, the rotating shaft 515 and the locking block 516 can rotate. Through the rotation of the locking block 516, when it touches the semi-circular protrusion at the top of the locking rod 521, it can squeeze the locking rod 521 to drive the armature 519 to squeeze the second spring 520, so that the locking rod 521 passes over the surface of the locking block 516 and is received towards the inside of the trigger seat 517. When the power connection mother end 52 and the power connection end 53 are completely connected, at this time the locking rod 521 is just opposite the locking groove opened inside the locking block 516, and then under the action of the second spring 520, the locking rod 521 can be inserted into the locking groove of the locking block 516 to complete the locking of the rotating shaft 515 and ensure the stable connection between the power connection mother end 52 and the power connection end 53.
