Referring to fig. 1, the driving frame 6 may swing the nozzle 2 around the rotation shaft 3 when moving up and down, so that the nozzle 2 may swing up and down, and the driving frame 6 may rotate the nozzle 2 around the support shaft 5 when moving left and right, so that the nozzle 2 may swing left and right. In the practical application process, the motor 10 drives the cam mechanism and the track 12 mechanism to work simultaneously, so that the nozzle 2 can swing in the vertical direction and the horizontal direction simultaneously, the scheme can conveniently carry out dust removal operation on the electrical cabinet, the labor intensity of operators is reduced, and the dust removal effect is improved.

In some embodiments, the track 12 mechanism includes a track disc 11, a track 12 is disposed on the track disc 11, the cam mechanism includes a cam body 13, the cam body 13 is an integral structure with the track disc 11, and the motor 10 drives the track disc 11 to rotate. The track 12 is recessed in the track disk 11, and the width of the track 12 is not limited and can be freely set. The cam body 13 may be provided coaxially with the track plate 11, and the cam body 13 may not be provided coaxially with the track plate 11. Because the track disc 11 and the cam body 13 are of an integrated structure, the motor 10 directly drives the track disc 11 and the cam body 13, and the track disc 11 and the cam body 13 have good synchronization performance.

In some embodiments, the driving rack 6 is provided with a sliding block 14 cooperating with the track 12, a part of the sliding block 14 extends into the track 12, and the sliding block 14 is cylindrical to reduce the abrasion between the sliding block 14 and the side wall of the track 12.

The driving frame 6 is also provided with a roller 16, and the roller 16 is rotatably connected to the driving frame 6 through a wheel shaft. The roller 16 is engaged with the cam body 13, and the length of the cam body 13 extending out of the track disk 11 is greater than the maximum stroke of the track 12 for driving the slider 14 to displace. This scheme has improved the stability ability in the dust removal mechanism working process, and the carriage 6 is at the left and right sides displacement in-process, and gyro wheel 16 can not break away from with cam body 13.

In some embodiments, the cabinet door 1 includes a body and a protruding rib 17 disposed around the cabinet door 1, the protruding rib 17 cooperates with the cabinet door 1 to form an accommodating cavity, the rotating shaft 3 is disposed on the protruding rib 17, a sliding cavity for positioning the driving rack 6 is formed between the protruding rib 17 and the cabinet door 1, and a portion of the driving rack 6 is located in the sliding cavity to displace the driving rack 6 relative to the cabinet door 1. The edge and the cabinet door 1 are of an integrated structure. The convex edge 17 is provided with a shaft hole, the rotating shaft 3 is rotatably connected in the shaft hole, and a rolling bearing is arranged between the rotating shaft 3 and the shaft hole. The wear between the rotary shaft 3 and the shaft hole is reduced. Through holes are uniformly distributed in the rotating shaft 3, the supporting shaft 5 penetrates through the through holes, and the supporting shaft 5 is welded in the through holes. The support shaft 5 may be directly welded to the rotary shaft 3.

The working principle is that the driving frame 6 is arranged in the sliding cavity, and referring to the orientation of fig. 1, the driving frame 6 can move up, down, left and right in the sliding cavity, but the driving frame 6 can not be separated from the sliding cavity, that is, the driving frame 6 can not move in the direction penetrating out of the paper surface. Because the displacement distance of the driving frame 6 is smaller, the structure can meet the displacement requirement of the driving frame 6. The lower end of the driving frame 6 is limited by the cam body 13 and the track disc 11.

The motor 10 rotates the orbital disc 11, and the following two actions occur simultaneously:

a. the track disk 11 rotates, and since the driving rack 6 cannot be displaced in a direction penetrating the paper, the slider 14 drives the driving rack 6 to be displaced left and right under the action of the side wall of the track 12, and the slider 14 interferes with the side wall of the track 12, and since the driving rack 6 is movable, the driving rack 6 is displaced left and right at this time. In the process of left-right displacement of the driving frame 6, the side wall of the pushing groove 7 interferes with the pushing teeth 9, so that the rotating frame 4 swings left and right around the supporting shaft 5, and the nozzle 2 swings left and right.

b. The cam body 13 rotates because the track disc 11 and the cam body 13 are of an integral structure. Therefore, the cam body 13 rotates while the orbit plate 11 rotates, and during the rotation of the cam body 13, the cam body 13 contacts the roller 16 on the driving frame 6, and the driving frame 6 is displaced up and down by the roller 16. In the process of vertical displacement of the driving frame 6, the top wall and the bottom wall of the pushing groove 7 interfere with the pushing teeth 9, so that the rotating frame 4 rotates around the rotating shaft 3, and the nozzle 2 swings up and down.

The nozzle 2 swings in two directions through the two actions, so that the air flow sprayed by the nozzle 2 can effectively remove dust on the electric control cabinet.

In the above-described operation b, the driving frame 6 is displaced up and down, and the slider 14 is always in the pushed-out state by the spring 15, so that the slider 14 is always in the track 12. Further, since the cam body 13 has a certain length, the roller 16 does not come off the cam body 13 during the operation a.

This scheme can replace artifical dust removal, has reduced operating personnel's intensity of labour to operating personnel's security has been improved.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
