[0042] Working principle: When the present invention is in use, when the DTU body 3 needs to be cooled, the shielding plate 6 needs to be separated from the cooling hole 2. Specifically, the electric push rod 4 is first opened, and the strip block 13 is driven to move by the contraction of the telescopic end of the electric push rod 4. The movement of the strip block 13 is divided into two processes:

[0043] Process 1: When the movable end of the electric push rod 4 moves from the initial end to point A, the movable block 17 moves with the strip block 13 under the action of the extrusion spring 1 27, thereby driving the connecting plate 12 to move upward, and further driving the shielding plate 6 to move upward, so that the heat dissipation hole 2 is opened, thereby facilitating the entry of outside air;

[0044] When the movable end of the electric push rod 4 moves to point A, the shielding plate 6 moves to the top, the heat dissipation hole 2 is fully opened, and the bar-shaped toothed plate 20 is meshed with the gear 19;

[0045] Process 2: Then the movable end of the electric push rod 4 continues to move upward, so that the movable end of the electric push rod 4 moves from point A to the end. At this time, the movable block 17 is in a relatively static state, and the strip tooth plate 20 moves upward to drive the gear 19 to rotate, and then drive the short shaft 16 and the winding wheel 10 to rotate, and the traction rope 14 is wound around the winding wheel 10, so that the traction rope 14 moves, thereby driving the bar box 7 and the rake 29 to move, and the movement of the bar box 7 drives the movable plate 24 to move, and then drives the bristles 26, the slide plate 25 and the cylinder 31 to move; the bristles 26 move on the heat dissipation hole 2 to clean the heat dissipation hole 2, so as to prevent the heat dissipation hole 2 from being blocked by dust, facilitate the flow of wind, and benefit the heat dissipation of the DTU body 3; and the cleaned dust falls into the collection box 8;

[0046] When cleaning the heat dissipation hole 2, the cylinder 31 slides in the flat groove 23. When the cylinder 31 finishes cleaning the heat dissipation hole 2, the cylinder 31 moves into the sliding groove 22 as the bar box 7 continues to move. Then, the cylinder 31 moves under the action of the sliding groove 22, and then drives the movable plate 24 to move into the bar box 7, so that the bristles 26 move into the bar box 7. Then, under the action of the nail rake 29, the fluff attached to the bristles 26 is cleaned, and the cleaned fluff falls into the collection box 8.

[0047] When the DTU body 3 does not need to dissipate heat, the electric push rod 4 is controlled to extend its movable end, so that the strip tooth plate 20 drives the gear 19 to reverse, so that the traction rope 14 is spread from the winding wheel 10, and then the strip box 7 is reset under the action of the reset spring 18; when the movable end of the electric push rod 4 moves to point A, the strip box 7 returns to the initial position; as the movable end of the electric push rod 4 continues to extend, the movable block 17 is separated from the connecting plate 12, and then under the action of the reset spring 1 5, the shielding plate 6 is reset to block the heat dissipation hole 2, so as to prevent dust from entering from the heat dissipation hole 2 when the DTU body 3 does not need to dissipate heat;

[0048] Among them, when the DTU body 3 needs to dissipate heat and the heat dissipation hole 2 also needs to be cleaned, at this time, as long as the movable end of the electric push rod 4 is controlled to move from the end to point A, and then move from point A to the end, the bristles 26 can be moved back and forth on the heat dissipation hole 2, thereby cleaning the dust on the heat dissipation hole 2;

[0049] Finally, when the dust in the collection box 8 needs to be cleaned, the DTU box body 1 is opened so that the top surface of the collection box 8 can clean the dust inside.

[0050] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
