[0052] By adopting the above technical solution, the output end of the motor 417 rotates to drive the first rotating shaft 403 and the second rotating shaft 412 to rotate, so as to provide power output.

[0053] Two fixed blocks 421 are fixedly provided on the outside of the heat dissipation tube 410, and a guide rod 422 is fixedly provided on the top of the fixed block 421, and an operating block 423 is fixedly provided on the top of the guide rod 422. A sliding block 424 is movably sleeved on the outside of the operating block 423, and the top of the sliding block 424 is fixedly photographed on the fixed rod 429. The top of the fixed rod 429 is fixedly connected to the dust cover 420, and a sliding groove 425 is opened on the outside of the operating block 423. A rotating plate 426 is rotatably provided on the outside of the sliding block 424, and a guide block 427 is fixedly provided on the outside of the bottom end of the rotating plate 426, and the guide block 427 is inserted in the sliding groove 425.

A No. 2 compression spring 428 is fixedly connected to the top of the inner wall of the sliding block 424 and the top of the operating block 423.

[0054] By adopting the above technical solution, the dust cover 420 can be adjusted in position, and when not in use, it will cover the heat dissipation tube 410 to prevent dust from entering.

[0055] Working principle: During the operation of the equipment, the motor 417 is started, so that the motor 417 starts to work, and the output end of the motor 417 rotates to drive the rotating rod 414 to rotate. The rotating rod 414 rotates through the synchronous wheel and the synchronous belt to rotate the two No. 1 rotating shafts 403. The rotation of the No. 1 rotating shaft 403 drives the exhaust fan 404 to rotate. The exhaust fan 404 rotates to draw the gas outside the box 1 into the box 1. At the same time, the rotation of the rotating rod 414 drives the No. 1 bevel gear 415 to rotate. The rotation of the No. 1 bevel gear 415 drives the mutually meshing No. 2 bevel gear 416 to rotate. The No. 2 bevel gear 416 rotates the No. 2 rotating shaft 412 to rotate. The rotation of the No. 2 rotating shaft 412 drives the exhaust fan 404 to rotate. The exhaust fan 404 rotates to extract the gas in the box 1. At the same time, the extracted hot air can be blown to the side through the dust cover 420, so that the gas can be in the box 1. The inner circulation can discharge the heat generated by the equipment in the box body 1, and prevent the high temperature from affecting the normal operation of the equipment. When the equipment is not in operation, the dust cover 420 is first pressed downward, so that the dust cover 420 moves downward to drive the fixing rod 429 to move downward. The fixing rod 429 moves downward to drive the sliding block 424 to move downward on the outer side of the operating block 423. The operating block 423 moves downward to first compress the No. 2 compression spring 428, and at the same time drive the rotating plate 426 to move downward. While the rotating plate 426 moves downward, it slides in the sliding groove 425 through the guide block 427, so that the guide block 427 moves to the bottom end of the sliding groove 425, and then stops. The guide block 427 is clamped in the sliding groove 425, so that the dust cover 420 covers the heat sink 410, thereby preventing dust from entering the box body 1 through the heat sink 410 when the equipment is not in operation.

[0056] When the data analysis device 110 in the box body 1 needs to be replaced and upgraded, the hexagonal nut 305 can be loosened first, and then the baffle 301 can be moved, so that the baffle 301 can move laterally with the assistance of the limit groove 302. After it is adjusted to a suitable position, the baffle 301 is fixed by installing the hexagonal nut 305. When the position of the mounting plate 201 needs to be adjusted, the operating ring 214 is pulled first, and the movement of the operating ring 214 drives the No. 1 wedge block 213 and the insertion rod 212 to move, so that the insertion rod 212 moves out of the insertion hole 203, and at the same time, the movement of the insertion rod 212 drives the fixed disk 215 to move, and the fixed disk 215 moves to compress the No. 1 compression spring 216. , so that the end of the No. 1 wedge block 213 and the end of the No. 2 wedge block 217 are on the same horizontal line, and then the No. 1 wedge block 213 is rotated to one hundred and eighty degrees, so that the raised end of the No. 1 wedge block 213 is in contact with the raised end of the No. 2 wedge block 217, and then the insertion rods 212 on both sides of the mounting plate 201 are disengaged from the insertion holes 203, and the height of the mounting plate 201 can be adjusted. After adjusting to a suitable height, the No. 1 wedge block 213 can be rotated one hundred and eighty degrees, and under the rebound action of the No. 1 compression spring 216, the insertion rod 212 is inserted into the insertion hole 203, thereby completing the height adjustment of the mounting plate 201, which can facilitate the subsequent adjustment and installation according to the upgraded device specifications.

[0057] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
