With reference to the above embodiments, the usage principle and the working process of the embodiments of the present invention are as follows:
when the blown wind is directly opposite to the first surface, the second surface, the third surface or the box door 201 of the electric box 200, the electric box 200 is kept still; when the blown wind is not directly opposite to the first surface or the second surface or the third surface of the electric box 200 or the box door 201, the wind deflector 220 drives the electric box 200 to rotate under the action of the wind power, so that the blown wind is directly opposite to the first surface or the second surface or the third surface of the electric box 200 or the box door 201.
Assuming that the blown wind directly faces the first surface of the power box 200, due to the wind force, the wind sensing plate 210 on the first surface can rotate along the hinge position and press down on the contact 310, so that the contact 310 is pressed down, the button 350 is triggered under the action of the compression spring 320, and then the slider on the first surface is controlled by the electric cylinder to ascend, and the slider drives the ventilation plate 230 on the first surface to ascend to a specified position along the slide way; meanwhile, the motor drives the ratchet gear 280 to rotate, and the ratchet gear 280 drives the wind shield 260 to rotate, so that the notch position on the wind shield 260 is opposite to the wind inlet 240 corresponding to the first surface; the ventilation plate 230 blocks large impurities in the air to prevent the impurities from blocking the air inlet 240, and then the air enters from the air inlet 240 corresponding to the first surface, exchanges heat with electrical components, and is blown out from the air outlet 250.
When the wind power is large, the ventilation plate 230 on the first surface is enabled to rotate towards the direction close to the wind shield 260 under the action of the wind power, in the rotating process, the ventilation plate 230 on the first surface abuts against the guide plate 271, so that the guide plate 271 rotates, the guide plate 271 drives the helical gear 272 to synchronously rotate, the helical gear 272 and the first tooth 2731 on the sliding plate 273 are always meshed, so that the sliding plate 273 moves, the sliding plate 273 drives the wind shield 260 to rotate through the matching of the third ratchet 2732 and the first ratchet 261, so that the wind shield 260 covers the wind inlets 240 corresponding to part of the first surfaces, the ventilation area of the wind inlets 240 corresponding to the first surfaces is reduced, and the phenomenon that the excessive small impurities enter the power box 200 due to the overlarge wind power is avoided; when the wind blowing to the first surface disappears or decreases, the ventilating plate 230 is reset by the torsion spring; the air-sensitive plate 210 is reset under the action of the pressure spring 320, and the button 350 is slowly bounced due to the action of the stopper 340 and the gear baffle plate 330, that is, the ventilation plate 230 falls down after a period of time, so that the recoil effect on the ventilation plate 230 can be achieved.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
