[0055] Embodiment 4:

[0056] This embodiment provides a ventilation pipe connection device for a data center computer room, which further includes the following structure based on the third embodiment:

[0057] like Figure 2 and Figure 10-12 As shown, a ventilation component 4 is installed on the inner wall of the driving component 1, and the ventilation component 4 includes an output shaft 401. A slot 404 is opened on the circumferential outer wall of the output shaft 401. A mounting sleeve 402 is slidably connected to the outer wall of the output shaft 401. Two blocks 405 are fixedly connected to the inner wall of the mounting sleeve 402. The blocks 405 are slidably connected to the inner wall of the slot 404. A plurality of fan blades 403 are fixedly connected to the outer wall of the mounting sleeve 402. An extension sleeve 406 is fixedly connected to the bottom of the mounting sleeve 402. A support sleeve 407 is rotatably connected to the inner wall of the extension sleeve 406.

[0058] The outer wall of the support sleeve 407 is fixedly connected with two connection frames 408, and the outer walls of the two connection frames 408 are both convex to form a limited position protrusion 409, and the inner walls of the two connection frames 408 are both rotatably connected with a rotating shaft 410, and the outer ends of the two rotating shafts 410 are sleeved with a torsion spring 412, and the ends of the rotating shafts 410 are both fixedly connected to the limited position sleeve 411, and the ends of the rotating shafts 410 are both fixedly connected with a pressure arm 413, one end of the torsion spring 412 is fixedly connected to the limited position sleeve 411, and the other end of the torsion spring 412 is fixedly connected to the connection frame 408. The pressure arm 413 stably squeezes the filter screen 207 under the torsion force of the torsion spring 412, thereby improving the stability of the filter screen installation and reducing the safety hazards caused by looseness.

[0059] Working principle: The first motor 105 drives the block 405 to rotate through the output shaft 401, drives the mounting sleeve 402 to rotate through the block 405, and drives the plurality of fan blades 403 to rotate through the mounting sleeve 402, thereby exchanging and flowing the air inside the machine room;

[0060] The worm 111 is driven to rotate by the second motor 109, and the worm 111 drives the worm wheel 110 to rotate. The worm wheel 110 drives one of the driving shafts 301 to rotate. When the driving shaft 301 rotates, multiple driving shafts 301 are driven to rotate synchronously through multiple bevel gears 303. Multiple rotating wheels 304 are driven to rotate through multiple driving shafts 301, and multiple clamping plates 306 are driven to rotate through the rotating wheels 304. The end of the clamping plate 306 abuts against the inside of the annular groove 210 and pushes the filter sleeve 205 to move downward, so that the filter sleeve 205 is separated from the end of the clamping plate 306. At the same time, when the clamping plate 306 rotates, it pushes the multiple connecting rings 203 to move downward respectively, so that the cloth bag 202 can be extended. At this time, the filter sleeve 205 drives the filter 207 to descend to a height that is convenient for workers to clean;

[0061] The operator disassembles and replaces the filter 207 by flipping the two pressing arms 413 at the same time. Under the torsion of the torsion spring 412, the bottom of the pressing arm 413 presses the top of the filter 207, thereby improving the stability of the filter installation.

[0062] When the filter sleeve 205 moves, the two connecting frames 408 are driven to move, the connecting frames 408 drive the supporting sleeve 407 to move, the supporting sleeve 407 drives the mounting sleeve 402 to move through the extending sleeve 406, and the mounting sleeve 402 drives the clamping block 405 to slide out from the inner wall of the clamping slot 404, thereby driving the multiple fan blades 403 to move, making it convenient for the operator to clean the dust on the surface of the fan blades 403;

[0063] The operation of the second motor 109 drives the worm 111 to rotate in the opposite direction, and the worm 111 drives the worm wheel 110 to rotate in the opposite direction, so that the rotating wheels 304 on the multiple driving shafts 301 rotate in the opposite direction, and the rotating wheels 304 drive the card plate 306 to rotate in the opposite direction, and the multiple connecting rings 203 are pushed upward by the card plate 306. The spiral steel wire 2021 installed inside the cloth bag 202 can reduce the shaking of the connecting ring 203 when it rises, so that the connecting ring 203 can be stably stored. When the connecting ring 203 at the bottom is lifted up by the card plate 306, the supporting ring 204 fixed at the bottom of the bottom connecting ring 203 The filter sleeve 205 can be prevented from shaking, so that the ends of the plurality of clamping plates 306 can be clamped in the annular groove 210. At this time, the clamping plates 306 are squeezed and slide into the mounting hole 305. When the clamping plates 306 slide, they drive the fixing plates 307 to move. The fixing plates 307 drive the connecting rods 308 to move. When the connecting rods 308 move, they squeeze the springs 309. When the filter sleeve 205 moves upward, it drives the sealing sleeve 209 to move upward, so that the sealing sleeve 209 slides into the bottom cover plate 101. At the same time, under the elastic force of the springs 309, the plurality of clamping plates 306 can clamp and fix the filter sleeve 205.

[0064] When the filter sleeve 205 moves upward, the support sleeve 407 is driven upward by the connecting frame 408, and the support sleeve 407 drives the installation sleeve 402 to move, so that the block 405 inside the installation sleeve 402 slides into the slot 404, thereby quickly installing the installation sleeve 402.

[0065] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
