[0014] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use: 1. A dynamic low-voltage swing protection mechanism is provided. Through the mutual cooperation between the components inside the dynamic low-voltage swing protection mechanism, the protection process when the distribution box fails is optimized. The temperature change inside the distribution box body is responded to in real time through the heat-conducting top block, the telescopic adjustment capsule and the temperature sensor. The temperature inside the distribution box is monitored in real time through the temperature sensor, so as to timely find the internal fault of the distribution box. When the temperature inside the distribution box rises rapidly and the maintenance personnel cannot respond in time, the position and state of the take-up roller and the lifting counterweight block are adjusted by the expansion of the telescopic adjustment capsule, and the negative pressure is generated inside the distribution box body by the sliding of the lifting counterweight block to prevent the occurrence of open flames inside the distribution box body and accelerate the damage of electrical components, thereby effectively improving the overall protection performance of the distribution box. After completing the inspection and maintenance of the faulty distribution box, the take-up roller is rotated in the opposite direction to rewind and reset the limit traction rope and the lifting counterweight block, thereby effectively improving the inspection and maintenance cost of the distribution box and improving the convenience and safety of the use of the distribution box. In addition, during the process of descending the lifting counterweight block, the driving turning plate and the deflection slider are driven by the mutual cooperation between the liquid storage telescopic bag and the driving telescopic bag, and in the process of the driving turning plate and the deflection slider moving, the limiting guide groove and the rotating spiral groove are cooperated to drive the driving vertical axis and the separation swing frame to swing, and in the process of the driving vertical axis and the separation swing frame swinging outward, the lightweight debris on the front of the distribution box body is pushed outward, thereby effectively preventing the open flame inside the distribution box body from spreading outward and causing greater damage, further improving the protective isolation of the distribution box, so that when a fault occurs inside the distribution box, corresponding protective operations can be performed without human participation, and maintenance personnel can quickly locate the faulty distribution box through the pop-up separation swing frame, further improving the safety of use and the convenience of inspection and maintenance of the distribution box.

[0015] 2. An internal continuous circulation temperature adjustment mechanism is provided. Through the mutual cooperation between the components inside the internal continuous circulation temperature adjustment mechanism, the heat dissipation process during the use of the distribution box is optimized. The airflow inside the distribution box body is continuously circulated by the circulation fan in conjunction with the air guide inner box and the air distribution top box. During the circulation of the airflow inside the distribution box body, the heat dissipation efficiency of the circulating airflow is accelerated by installing a top cover and a heat dissipation inclined plate, thereby ensuring that the distribution box can be kept within a suitable range during long-term use. When the exhaust side valve is not opened, the circulating airflow can maintain the internal circulation of the distribution box body, thereby ensuring efficient heat dissipation inside the distribution box while keeping the inside of the distribution box body clean, effectively improving the use stability of the distribution box; When it is necessary to dissipate heat efficiently inside the distribution box, the cooling water in the liquid storage bottom box and the heat dissipation back box is driven by the cooling pump to circulate continuously, so as to absorb and transfer the heat on the back of the distribution box body through the circulation of cooling water, and continuously blow the sealed box door and the outside of the heat dissipation back box through the exhaust side valve and the blowing flat box, thereby further improving the heat dissipation efficiency during the cooling process of the distribution box, further improving the service life of the distribution box, effectively avoiding the reduction of the service life of the distribution box due to long-term overheating during use, and improving the safety of the distribution cabinet.

[0016] In summary, through the mutual cooperation between the components within the dynamic low-voltage swing protection mechanism and the internal continuous circulation temperature control mechanism, the temperature regulation process during the operation of the distribution box is optimized. During the long-term continuous use of the distribution box, the circulating fan drives the airflow inside the distribution box body to circulate continuously, and the internal circulation or external circulation is selected according to the heat dissipation performance requirements of the distribution box. The airflow is filtered during the airflow circulation process to ensure efficient heat dissipation inside the distribution box while maintaining the cleanliness of the inside of the distribution box, thereby effectively improving the stability and service life of the distribution box. When overheating or open flames occur inside the distribution box due to a fault, negative pressure is generated inside the distribution box to prevent the generation of open flames, thereby reducing the damage to the internal components of the distribution box caused by the fault, and the front of the distribution box body is cleaned by the swing of the separation swing frame to prevent the damage caused by the fault of the distribution box body from spreading outward, thereby effectively improving the safety and convenience of the use of the distribution box.

The circulation fan 503 cooperates with the air guide inner box 502 and the air distribution top box 508 to continuously circulate the airflow inside the distribution box body 1, and during the circulation of the airflow inside the distribution box body 1, the top cover 501 and the heat dissipation inclined plate 509 are installed to accelerate the heat dissipation efficiency of the circulating airflow, thereby ensuring that the distribution box can be kept within a suitable range during long-term use, and when the exhaust side valve 504 is not opened, the circulating airflow can maintain the circulation inside the distribution box body 1, thereby ensuring efficient heat dissipation inside the distribution box while keeping the inside of the distribution box body 1 clean, effectively improving the use stability of the distribution box; When it is necessary to dissipate heat efficiently inside the distribution box, the cooling water in the liquid storage bottom box 513 and the heat dissipation back box 515 is driven by the cooling pump 514 to circulate continuously, so as to absorb and transfer the heat on the back of the distribution box body 1 through the circulation of cooling water, and the sealed box door 2 and the outside of the heat dissipation back box 515 are continuously blown through the exhaust side valve 504 and the blowing flat box 505, thereby further improving the heat dissipation efficiency during the cooling process of the distribution box, further improving the service life of the distribution box, effectively avoiding the reduction of the service life of the distribution box due to long-term overheating during the use of the distribution box, and improving the safety of the distribution cabinet.

[0021] Working principle and use process of the present invention: In the process of using the power distribution cabinet, the present invention needs to first connect the electrical components 3 inside the power distribution box body 1 with the external cables, and close the sealed box door 2 to seal the power distribution box body 1, so as to complete the preliminary installation of the power distribution cabinet; During the continuous use of the distribution box, when the electrical components 3 inside the distribution box generate abnormal heat, the heat inside the distribution box body 1 is absorbed and collected by the heat-conducting top block 408, and then the absorbed heat is transferred to the telescopic adjustment capsule 409 through the heat-conducting top block 408 to heat the mixed gas, so that the telescopic adjustment capsule 409 expands downward after absorbing heat, and drives the sliding vertical shaft 412 and the limiting sliding shaft 413 to slide downward synchronously during the downward expansion of the telescopic adjustment capsule 409. At the same time, the temperature inside the distribution box body 1 is monitored in real time by the temperature sensor 414, and gradually slides downward along the limiting sliding groove 407 during the downward sliding of the limiting sliding shaft 413, and after the limiting sliding shaft 413 completely slides downward out of the limiting sliding groove 407, the limit on the take-up roller 406 is cancelled, so that the take-up roller 406 can be rotated through the cooperation between the connecting guide ring 405 and the mounting top frame 404; When the limiting sliding shaft 413 slides out from the limiting sliding groove 407, the limiting traction rope 415 can no longer limit the lifting counterweight block 416. The lifting counterweight block 416 will continue to slide downward along the inside of the driving side box 401 under the action of gravity, and guide the limiting traction rope 415 through the limiting guide roller 402 and the wire groove hole 403 to prevent the limiting traction rope 415 from deviating during the movement. In the process of sliding the lifting counterweight block 416, the gas inside the distribution box body 1 is sucked through the exhaust rectangular box 417, so that the gas inside the distribution box body 1 can quickly diffuse into the driving side box 401, thereby reducing the pressure inside the distribution box body 1, and preventing the generation of open flames inside the distribution box body 1. During the vertical downward sliding of the lifting counterweight block 416, the liquid storage bellows 418 will be squeezed synchronously, and after the liquid storage bellows 418 is squeezed, the transmission oil inside the liquid storage bellows 418 will be introduced into the driving bellows 420 through the liquid guide valve 419. As the transmission oil inside the driving bellows 420 increases, it will gradually expand upward, and while the driving bellows 420 expands upward, it drives the driving turning plate 421 to rise synchronously, and during the rising of the driving turning plate 421, it drives the deflection slider 423 to slide upward along the inner wall of the limiting guide groove 422, and during the upward sliding of the deflection slider 423, it cooperates with the rotating spiral groove 425 to drive the driving shaft 424 to rotate, and during the rotation of the driving shaft 424, it drives the separation swing frame 427 to swing outward synchronously through the driving vertical shaft 426, and during the swinging of the separation swing frame 427, push away the light debris in front of the sealed box door 2 to prevent the open fire inside the distribution box body 1 from spreading outward; When the distribution box is used for a long time and the interior of the distribution box body 1 needs to be continuously cooled, a continuous circulating airflow is generated in the air guide inner box 502 through the circulating fan 503, and the circulating airflow is driven by the air guide inner box 502 to pass through the interior of the filter rectangular box 506, and the dust in the circulating airflow is intercepted by the filter rectangular box 506 to improve the cleanliness of the circulating airflow, and then the airflow inside the air guide inner box 502 is introduced into the interior of the air distribution top box 508 through the air guide top pipe 507, and when the circulating airflow flows through the two ends of the air distribution top box 508, the high-temperature airflow inside the air distribution top box 508 is assisted in heat dissipation through the heat dissipation inclined plate 509, so as to achieve rapid heat dissipation inside the distribution box body 1; At the same time, the circulating airflow after heat dissipation in the air distribution top box 508 is introduced into the air distribution flat box 511 through the reflux flat tube 510, and the circulating airflow is evenly diffused to both sides of the distribution box body 1 through the air distribution flat box 511, so as to expand the contact area between the circulating airflow and the components inside the distribution box body 1, effectively expanding the heat dissipation efficiency during the use of the distribution box, and at the same time, the circulating water in the liquid storage bottom box 513 is driven to continuously enter the heat dissipation back box 515 through the cooling pump 514, and the cooling water in the heat dissipation back box 515 is returned to the liquid storage bottom box 513 through the reflux capillary 516, and then the inside of the distribution box body 1 is assisted in heat dissipation in the process of the circulating water flowing through the heat dissipation back box 515, and when it is necessary to enhance the heat dissipation efficiency of the distribution box, the exhaust side valve 504 is opened to introduce part of the airflow in the air guide inner box 502 into the blowing flat box 505, so that the airflow in the blowing flat box 505 can be blown to the outside of the sealed box door 2 and the heat dissipation back box 515 at the same time, further improving the heat dissipation efficiency of the distribution box.
