Specifically, when the inner top of the waterproof top cover 102 presses the top end of the cabinet body 101, the pull rope 603 is in a relaxed state, and at this time, the shaft sleeve 402 is driven by the pressure spring 405 through the chassis 403 to realize the compression fit with the first friction wheel 204 with the second friction wheel 401;
when the cabinet body 101 needs to be radiated, the driving motor 202 is controlled to drive the driving shaft 203 to rotate;
on one hand, the driving shaft 203 drives the first worm wheel 301 through the first worm 205 to drive the driven shaft 302 to rotate, so that the longitudinal fan 303 works to draw air upwards;

as the top cover 102 rises, the driven member 5 and the transmission member 4 also rise, and the pull rope 603 gradually tensions and pulls the push-pull rod 601; referring to fig. 4, since the chuck 602 and the annular groove 404 are in the corresponding T shape, they cannot be separated from each other, so that the push-pull rod 601 further limits the chassis 403, the shaft sleeve 402, and the second friction wheel 401 to ascend, and the second friction wheel 401 and the first friction wheel 204 are separated and lose fit, so that the transmission member 4 stops rotating, the driven member 5 and the threaded section 504 thereon also stop rotating, and at this time, the waterproof top cover 102 ascends to the highest position; as shown in fig. 1, at this time, the waterproof top cover 102 can still cover the top of the cabinet body 101 to prevent rain;
at this time, the heat dissipation assembly 3 still works, the longitudinal fan 303 still performs air draft, and heat in the cabinet body 101 is discharged through a heat dissipation channel formed between the waterproof top cover 102 and the top of the cabinet body 101.
When the top of the cabinet body 101 needs to be sealed again, the threaded section 504 can be directly driven to rotate reversely through the hand wheel 505, so that the waterproof top cover 102 moves downwards;
the threaded section 504 can be driven by the hand wheel 505 to rotate reversely slightly, so that the waterproof top cover 102 moves downwards slightly, the second friction wheel 401 and the first friction wheel 204 can be pressed and matched again, the driving motor 202 is controlled to rotate the driving shaft 203 reversely, and the driving part 4 and the driven part 5 rotate reversely due to the reverse rotation of the driving shaft 203, so that the threaded section 504 rotates reversely and is in threaded fit with the second support 105, and the waterproof top cover 102 moves downwards until the covering is completed.
