The first advantageous point of the present invention is explained by the following:
before the work starts, the center of a cooling fan arranged in the power distribution cabinet 1 and the center of the air valve block 4 are located on the same horizontal line, the sizes of the opening ends of the first air valve 41 and the second air valve 42 can be adjusted according to specific conditions, the pneumatic extrusion sheet 23 and the inner sliding rod 24 are made of light materials, and when the cooling fan works, because the inside of the power distribution cabinet 1 needs to be fully cooled, the wind power of the cooling fan is far larger than the elastic force of the pneumatic spring 25;
as can be seen from fig. 7, when the heat dissipation fan in the power distribution cabinet 1 is turned on, because the first air valve 41 is provided with the one-way valve port, and the single-line valve port of the first air valve 41 points to the inside of the air inlet 22 from the end of the heat dissipation fan, the wind blown by the heat dissipation fan can enter the inside of the air inlet 22 through the first air valve 41, and because the second air valve 42 is provided with the extrusion valve port, under the action that the wind power is much larger than the elastic force of the pneumatic spring 25, part of the wind power rebounded from the inside of the air inlet 22 is discharged through the second air valve 42, but due to the extrusion consumption, the wind power of the rebounded wind is small, and the normal heat dissipation process is not affected;
according to fig. 3, when wind enters the pneumatic sliding tube 21, the pneumatic extrusion piece 23 and the inner sliding rod 24 start to be pushed to move, the pneumatic spring 25 is extruded in the process, due to the fact that the cross section of the side wall of the inner sliding rod 24 is arranged in a concave structure, under the condition that the contact surface is reduced, the friction force in the pneumatic sliding tube 21 and the inner sliding rod 24 is reduced, meanwhile, due to the fact that the limiting ring at the port of the pneumatic extrusion piece 23 is arranged, the diameter of the inner ring of the limiting ring is smaller than that of the pneumatic extrusion piece 23, the pneumatic extrusion piece 23 cannot be ejected out of the tube of the pneumatic sliding tube 21 under the effect of the pneumatic spring 25 which is always in a compressed state, and meanwhile, due to the fact that the interval between the pneumatic sliding tube 21 and the power distribution cabinet 1 is smaller than the length of the inner sliding rod 24, the tube separation phenomenon of the inner sliding rod 24 cannot occur in the process of wind extrusion;
after the heat dissipation operation is finished, the heat dissipation fan stops working, when the wind pressure on the pneumatic extrusion sheet 23 slowly disappears and reaches a certain critical value, the pneumatic spring 25 starts to push the pneumatic extrusion sheet 23 and the air inlet 22 to perform return motion, because the first air valve 41 is arranged as a one-way valve port, the second air valve 42 performs ventilation operation under the extrusion action of the internal pneumatic extrusion sheet 23 on air, and at the moment, the second air valve 42 performs a blowing cleaning function on the heat dissipation fan;
from what is described herein, it can be seen that: the invention realizes the blowing and cleaning functions of the cooling fan when the cooling fan stops working by utilizing the matching action among the air inlet 22, the inner slide rod 24, the pneumatic spring 25 and the ventilation component and the elastic extrusion between the wind power of the cooling fan and the pneumatic spring 25, thereby achieving the timely blade cleaning function after the heat dissipation is finished each time.
The second advantageous point of the present invention is explained by the following:
before the work begins, the middle part of the dustproof baffle plate 36 is made of extensible materials;
as can be seen from fig. 3, when the cooling fan is working, the movement of the inner sliding rod 24 drives the meshing wheel 28 to move, the meshing wheel rotating rod 27 starts to rotate, and because the meshing wheel rotating rod 27 and the rotating end of the supporting plate 26 are provided with the limiting blocks, the meshing wheel rotating rod 27 does not roll when rotating;
as can be seen from fig. 5, at this time, the winding reel 3 starts to rotate with the rotation of the engaging reel rotating lever 27, and the winding process of the movable cord 32 starts;
as can be seen from fig. 6, in the process that the driving rope 32 is wound, the combined pull rod 33 is pulled to move inwards, due to the arrangement of the limiting sliding groove plate 34, the combined pull rod 33 is limited on the path of the inward position, at this time, the sliding groove rotating rod 35 which is rotatably connected with the combined pull rod 33 slides inside the limiting sliding groove plate 34, due to the rotary connection between the rotating plate rotating rod 37 and the side wall of the power distribution cabinet 1, and in the process that the dust-proof baffle 36 is moved in the sliding groove rotating rod 35, due to the adoption of the extensible material in the middle of the dust-proof baffle 36, when the dust-proof baffle 36 is moved to the end opposite to the initial position, the whole sealing device is opened, and the ventilation of the net mouth is started;
as can be seen from fig. 2, in the opening process, the outward end of the dustproof baffle 36 collides with the heat dissipation mesh opening 11, so as to collide and raise dust at the port of the heat dissipation mesh opening 11, and the dust is cleaned by the heat dissipation wind coming out from the opening and closing wind opening between the dustproof baffles 36;
as can be seen from fig. 6, after the work is finished, the inner sliding rod 24 is reset, the meshing wheel 28 rotates simultaneously, and because a clockwork spring is arranged between the rotating plate rotating rod 37 and the rotating side wall of the power distribution cabinet 1, the clockwork spring pulls the rotating plate rotating rod 37 to rotate and reset, and simultaneously pulls the combined pull rod 33 to displace outwards and restore to the sealing state again;
from what is described herein, it can be seen that: the invention realizes the opening and closing functions of the dustproof baffle 36 when the cooling fan works and the closing when the cooling fan stops by the matched action of the rolling rotating wheel 3, the driving rope 32, the driving component and the sealing component and the driving rolling generated by wind power.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
