The setting of the drainage groove 202 is compatible with the concave rotating plates 203, so that rainwater will not enter the switchgear body 1 from the gaps on both sides of the concave rotating plates 203.

[0026] In this embodiment, a bidirectional screw rod 8 is rotatably connected between the two ends of the inner side of the top cover 2, and the threads at both ends of the bidirectional screw rod 8 are symmetrically arranged. A motor 9 is fixedly connected to one end of the outer wall of the top cover 2, and the output end of the motor 9 passes through the top cover 2 and is fixedly connected to one end of the bidirectional screw rod 8.

[0031] Working principle: This type of active heat dissipation box-type switchgear is internally provided with a temperature sensor and a controller, and the controller is electrically connected to the temperature sensor and the motor 9 respectively. When in use, when the temperature inside the switchgear body 1 is high, the two exhaust fans 6 work to discharge the hot air inside the switchgear body 1 through the upper heat dissipation holes 101, so that a negative pressure is formed between the inside of the switchgear body 1 and the outside, so that the outside air enters the switchgear body 1 through the lower heat dissipation holes 102, and the cycle is repeated, so that the air inside the switchgear body 1 is exchanged to achieve a cooling effect. When the temperature inside the switchgear body 1 cannot be cooled well by the above method, the hot air will accumulate on the inside of the switchgear body 1 due to its low density. At this time, the motor 9 is started to rotate the bidirectional screw rod 8, and the two first screw blocks 10 are close to each other. Under the action of the strip hole 11 and the sliding rod 701, the rectangular frames 5 on both sides move along the L-shaped sliding hole 401 with the exhaust fan 6, so that the rectangular frame 5 is finally level with the top cover 2. At this time, the exhaust direction of the exhaust fan 6 is upward, and the two second screw blocks 12 are close to each other. Under the action of the connecting rod 13, the sliding rod 16 and the strip inclined hole 15, the two concave rotating plates 203 on the top are unfolded, so that the top of the top cover 2 can quickly discharge hot air, cooperate with the setting of the two exhaust fans 6, and at the same time, the upper heat dissipation holes 101 and the lower heat dissipation holes 102 are used to suck air from the outside to achieve rapid discharge of hot air inside the opening and closing body 1.
