[0014] Compared with the prior art, the present invention provides a power distribution cabinet with good heat dissipation, which has the following beneficial effects: (1) This power distribution cabinet with good heat dissipation can automatically clean the dust on the filter screen as needed, thereby avoiding the situation where dust clogs the mesh of the filter screen after long-term use, ensuring that the normal heat dissipation of the filter screen is not affected, and thus ensuring the heat dissipation effect of the power distribution cabinet. (2) The power distribution cabinet with good heat dissipation effect has heat dissipation vents on the front and rear sides of the power distribution cabinet body. When the cooling fan is working, it can quickly exhaust the hot air inside the cabinet and at the same time draw in the outside air to form efficient air convection. Compared with the traditional method of relying on natural heat dissipation or simple fan heat dissipation, this forced air convection can remove heat more quickly, effectively reduce the internal temperature of the power distribution cabinet, ensure that the electrical components operate in a suitable temperature environment, and extend their service life.
[0015] (3) The power distribution cabinet with good heat dissipation has the motor assembly set on the lower side of the fixed block, which can effectively reduce the damage to the motor assembly from external collisions, dust, rain, etc., reduce the possibility of equipment damage, extend the service life of the motor, and reduce the cost of equipment maintenance and replacement.
[0016] (4) The distribution cabinet with good heat dissipation has protective blocks that can protect the meshing parts. External dust, rainwater, etc. can affect the meshing between gears and gear rings, ensuring the stable operation of the meshing connection. (5) The heat dissipation effect of the distribution cabinet is good. The limiting effect of the rotating ring groove on the rotating ring can ensure that the rotating ring rotates smoothly in the fixed track without swaying or deviating. This allows the rotating block to move accurately along the predetermined path, thereby enabling the cleaning block to contact the filter screen stably and improving the uniformity and thoroughness of cleaning.

[0023] Please see Figures 1 to 6This invention provides a novel technical solution: a power distribution cabinet with good heat dissipation, comprising a cabinet body 1, a cabinet door 2 installed on the left side of the cabinet body 1, the cabinet door 2 and the cabinet body 1 being rotatably connected via a pivot, a door handle 3 fixedly connected to the left side of the cabinet door 2, the door handle 3 being equipped with a lock cylinder structure, heat dissipation vents 4 being provided on both the front and rear sides of the cabinet body 1, both heat dissipation vents 4 extending into the interior of the cabinet body 1, cooling fans 5 being fixedly connected to the inner walls of both heat dissipation vents 4, fixing blocks 6 being fixedly connected to both the front and rear sides of the cabinet body 1, heat dissipation grooves 7 being provided on the opposite surfaces of the two fixing blocks 6, the two heat dissipation grooves 7 being respectively connected to the two heat dissipation vents 4. Both heat dissipation slots 7 have filters 8 fixedly connected inside, which can filter the incoming air. Both fixed blocks 6 are equipped with cleaning mechanisms, which can clean the dust and other debris intercepted on the filters 8, thus preventing the filters 8 from becoming clogged. The two cleaning mechanisms have the same connection structure and are arranged symmetrically front and back. The following description focuses on the front cleaning mechanism, which includes a rotating ring groove 9, a rotating ring 10, a toothed ring 11, a rotating block 12, a connecting ring groove 13, two connecting rods 14, a mounting groove 15, a cleaning block 16, a protective block 17, a transmission groove 18, a connecting groove 19, a motor assembly 20, and a gear 21.
[0024] Furthermore, a rotating ring groove 9 is formed inside the fixed block 6, a rotating ring 10 is rotatably connected inside the rotating ring groove 9, a toothed ring 11 is fixedly sleeved on the outer surface of the rotating ring 10, a rotating block 12 is mounted on the front side of the fixed block 6, a connecting ring groove 13 is formed on the front side of the fixed block 6, and the rear side of the connecting ring groove 13 extends into the interior of the rotating ring groove 9. Two connecting rods 14 are fixedly connected to the rear side of the rotating block 12, the two connecting rods 14 are arranged symmetrically on the left and right, and the rear sides of the two connecting rods 14 extend into the interior of the connecting ring groove 13. The two connecting rods 14 extend into the interior of the rotating ring groove 9 through the connecting ring groove 13, and the rear sides of the two connecting rods 14 are fixedly connected to the rotating ring 10. An installation groove 15 is formed on the upper side of the rotating block 12, and the lower side of the installation groove 15 extends out of the rotating block 12. A cleaning block 16 is fixedly connected inside the installation groove 15. The rear part of the cleaning block 16 is a cleaning bristle. The protective block 17 is fixedly connected to the lower side of the fixed block 6. The transmission groove 18 is opened inside the protective block 17, and the upper side of the transmission groove 18 extends out of the protective block 17. The connecting groove 19 is opened on the lower side of the fixed block 6, and the upper side of the connecting groove 19 extends into the interior of the rotating ring groove 9. The connecting groove 19 is connected to the transmission groove 18. The motor assembly 20 is fixedly connected to the lower side of the fixed block 6. The motor assembly 20 is located at the rear side of the protective block 17. The output end of the motor assembly 20 is fixedly connected to the transmission shaft. The front end of the transmission shaft extends rotatably into the interior of the transmission groove 18. The front end of the transmission shaft is rotatably connected to the front wall of the transmission groove 18. The gear 21 is fixedly sleeved on the outer surface of the transmission shaft. The gear 21 is located inside the transmission groove 18. The gear 21 is meshed with the gear ring 11 through the connecting groove 19.
[0025] Furthermore, when the switchgear body 1 starts working, it generates heat during operation. The heat dissipation vents 4 on the front and rear sides extend into the interior of the switchgear body 1. The cooling fan 5, which is fixedly connected to the inner wall of the heat dissipation vent 4, starts working and exhausts the hot air inside the switchgear body 1 through the heat dissipation vent 4 to achieve a heat dissipation effect. At the same time, after the cooling fan 5 exhausts the air inside the switchgear body 1, a negative pressure will be formed inside the switchgear body 1, which will then draw in external air into the switchgear body 1. When the external air enters the switchgear body 1 through the heat dissipation vent 4, it will first pass through the heat dissipation groove 7 opened on the fixed block 6. The filter screen 8 fixedly connected inside the heat dissipation groove 7 can filter the incoming air and intercept dust and other impurities in the air to prevent them from entering the switchgear body 1 and affecting the normal operation of electrical components.
[0026] When a large amount of dust and other debris is trapped on the filter screen 8, the motor assembly 20 is activated. The output end of the motor assembly 20 drives the drive shaft to rotate, which in turn drives the gear 21, which is fixedly sleeved on its outer surface, to rotate. The rotation of the gear 21 drives the gear ring 11 to rotate, which in turn drives the rotating ring 10 to rotate inside the rotating ring groove 9. When the rotating ring 10 rotates, it drives the two connecting rods 14 to move within the connecting ring groove 13, which in turn drives the rotating block 12 to move. A cleaning block 16 is fixedly connected to the mounting groove 15 on the upper side of the rotating block 12. The rear part of the cleaning block 16 is a cleaning bristle. The movement of the rotating block 12 drives the movement of the cleaning block 16, and the cleaning bristles clean the dust trapped on the filter screen 8. Dust and other debris are cleaned to prevent the filter screen 8 from clogging. The protective block 17 is fixedly connected to the lower side of the fixed block 6, providing a certain degree of protection for the motor assembly 20 and other related components. The rotating ring groove 9 is opened inside the fixed block 6 to provide rotation space for the rotating ring 10. The connecting ring groove 13 is opened on the front side of the fixed block 6 and extends into the rotating ring groove 9 on the rear side, making it convenient for the connecting rod 14 to connect the rotating block 12 and the rotating ring 10. The transmission groove 18 is opened inside the protective block 17 and extends out of the protective block 17 on the upper side. The connecting groove 19 is opened on the lower side of the fixed block 6 and extends into the rotating ring groove 9 on the upper side and communicates with the transmission groove 18, providing a channel for the transmission of the gear 21 and the gear ring 11.
[0027] Furthermore, this method allows for the automatic cleaning of dust on the filter screen 8 as needed, thus preventing dust from clogging the mesh of the filter screen 8 after prolonged use. This ensures that the filter screen 8 can dissipate heat normally without being affected, thereby guaranteeing the heat dissipation effect of the power distribution cabinet.
