DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0027] Reference Figure 1-Figure 6 A high-efficiency and energy-saving cooling air device for a data center comprises a purification room shell 1, at both ends of which an air inlet pipe 2 and an air outlet pipe 3 are fixedly installed, a filter screen 4 is fixedly installed in the purification room shell 1, a mounting rod 5 is rotatably installed on the surface of the filter screen 4, one end of the mounting rod 5 is provided with a threaded opening, a threaded rod 6 is threadedly installed in the threaded opening, a plurality of scraping rods 7 that are in sliding contact with the filter screen 4 are fixedly installed on the surface of the mounting rod 5, the threaded rod 6 is restricted in rotation by a first restriction component, the first restriction component comprises a first restriction groove 13 horizontally provided on the inner wall of the purification room shell 1 and a first restriction rod 14 fixedly installed on the surface of the threaded rod 6, one end of the first restriction rod 14 is slidably arranged in the first restriction groove 13, a spring rod 30 is provided in the mounting rod 5, and both ends of the spring rod 30 are rotatably connected to the threaded rod 6 and the filter screen 4.

[0028] A rotating rod is horizontally rotatably installed in the air intake pipe 2 through an installation component, and the installation component includes a rotating ring 17 rotatably installed on the rotating rod and two support rods symmetrically fixedly installed on the outer ring wall of the rotating ring 17, and the ends of the support rods are fixedly connected to the inner wall of the air intake pipe 2, and a rotating blade 8 is fixedly sleeved on the rotating rod, and a reciprocating screw 9 is fixedly installed on one end of the rotating rod, and a slider 10 is threadedly sleeved on the reciprocating screw 9. A push block 12 is fixedly installed on the surface of the slider 10 through two connecting rods 11, and the slider 10 is restricted in rotation by a second limiting component. The second limiting component includes a second limiting groove 15 horizontally opened on the wall of the air intake pipe 2 and a second limiting rod 16 fixedly installed on the surface of the slider 10, one end of the second limiting rod 16 is slidably configured in the second limiting groove 15, and the push block 12 corresponds to the position of the threaded rod 6.

[0029] When gas passes through the intake pipe 2 at high speed, the rotating blade 8 will be driven by the force of the gas to rotate with the rotating rod and the reciprocating screw 9, and the slider 10 threadedly sleeved on the reciprocating screw 9 will drive the push block 12 to move laterally under the limiting action of the second limiting groove 15 and the second limiting rod 16. During the movement, the push block 12 will intermittently abut against the threaded rod 6 and push the threaded rod 6 to move. Since the threaded rod 6 cannot rotate under the limiting action of the first limiting groove 13 and the first limiting rod 14, the mounting rod 5 will rotate with multiple scraper rods 7 under the cooperation of the thread. During the rotation, the multiple scraper rods 7 will scrape off the dust and impurities attached to the surface of the filter 4, thereby achieving the effect of cleaning the filter 4. The filter 4 can be cleaned without an additional electric drive device, thereby reducing the electricity cost.

[0030] When the push block 12 is in the process of moving and resetting, the pressing force exerted by the push block 12 on the threaded rod 6 will gradually disappear, and the threaded rod 6 will move and reset under the elastic potential energy of the spring rod 30 until the push block 12 no longer resists the threaded rod 6. At this time, when the push block 12 moves, the threaded rod 6 will not move, and the mounting rod 5 will not rotate with the multiple scraper rods 7, thereby not cleaning the surface of the filter screen 4. Until the push block 12 moves again to resist the threaded rod 6, the multiple scraper rods 7 will clean the surface of the filter screen 4, that is, the cleaning work of the filter screen 4 is intermittent, reducing the wear between the contact surface of the scraper rod 7 and the filter screen 4.

[0031] The surface of the clean room shell 1 is provided with an installation opening 18, and a placement box 19 is slidably inserted in the installation opening 18, and an air filter element 20 is placed in the placement box 19. The left and right side walls of the placement box 19 are fixedly installed with slide seats 21. The surface of the clean room shell 1 is symmetrically fixed with installation blocks, and the lower surface of the installation block is vertically fixed with a slide rod 22. The two slide seats 21 are respectively slidably sleeved on the two slide rods 22. The placement box 19 is locked by a locking assembly, which includes two moving rods 23, two triangular locking blocks 24 respectively fixedly installed at the ends of the two moving rods 23, and two respectively sleeved on the two slide rods. The telescopic spring 25 at the end of the moving rod 23, a trapezoidal rod 26 is vertically fixedly installed on the upper surface of the slide seat 21, a through hole 27 for the trapezoidal rod 26 to pass through is opened on the upper surface of the mounting block, a support plate is fixedly installed on the upper surface of the mounting block, a through hole is opened on the surface of the support plate, the two moving rods 23 are respectively slidably inserted in the two through holes, and a pulling block 31 is fixedly installed at the end, the two ends of the telescopic spring 25 are respectively fixedly connected to the pulling block 31 and the supporting plate, a locking hole 28 for the locking block 24 to enter is opened on the surface of the trapezoidal rod 26, and the inclined surfaces of the two trapezoidal rods 26 are respectively in sliding contact with the inclined surfaces of the two locking blocks 24.

[0032] When the air filter 20 in the placement box 19 needs to be replaced, it is only necessary to pull the two pull blocks 31 in the direction away from the trapezoidal rod 26, control the two locking blocks 24 to move out of the two locking ports 28 respectively, so as to unlock the two trapezoidal rods 26, and then control the placement box 19 to move downward until the air filter 20 is exposed to the outside, and then replace it.

[0033] After the replacement is completed, the placement box 19 is controlled to move up, and the top ends of the two trapezoidal rods 26 will pass through the two through-holes 27 respectively, and the inclined surfaces of the two trapezoidal rods 26 will slide in contact with the inclined surfaces of the two locking blocks 24 respectively. Under the action of the inclined surface pressure, the two locking blocks 24 will move in the direction away from the trapezoidal rods 26, and the telescopic springs 25 will stretch at this time until the placement box 19 completely enters the installation opening 18. At this time, the two locking blocks 24 will correspond to the positions of the two locking openings 28 respectively, and the pressing force of the trapezoidal rods 26 on the locking blocks 24 disappears. The two locking blocks 24 will quickly move and reset under the elastic potential energy of the two telescopic springs 25, and be inserted into the two locking openings 28 respectively, thereby completing the locking of the placement box 19, which is convenient and quick, and improves the work efficiency of replacing the air filter element 20.

[0034] A thread is formed at the bottom end of the slide rod 22 , and a nut 29 is threadedly sleeved on the bottom end of the slide rod 22 . A protective layer of rubber material is bonded to the upper surface of the nut 29 .

[0035] The nut 29 can prevent the placement box 19 from sliding down directly under its own gravity and falling to the ground after the placement box 19 is unlocked. At the same time, when the placement box 19 needs to be completely removed, the nut 29 can be rotated to separate the nut 29 from the slide bar 22. At this time, the blocking effect of the nut 29 on the placement box 19 will disappear, and then the placement box 19 can be removed from the two slide bars 22.

[0036] The protective layer of rubber material has good elasticity, so as to reduce the damage to the surface of the placement box 19 when the placement box 19 slides down and contacts the nut 29 under the action of its own gravity.

[0037] In the utility model, when gas passes through the intake pipe 2 at high speed, the rotating blade 8 will be driven by the force of the gas to rotate with the rotating rod and the reciprocating screw 9, and the slider 10 threadedly sleeved on the reciprocating screw 9 will carry the push block 12 to move laterally under the limiting action of the second limiting component. During the movement, the push block 12 will intermittently resist the threaded rod 6 and push the threaded rod 6 to move. Since the threaded rod 6 cannot rotate under the limiting action of the first limiting component, the mounting rod 5 will rotate with multiple scraper rods 7 under the cooperation of the thread. During the rotation, the multiple scraper rods 7 will scrape off the dust and impurities attached to the surface of the filter 4, so as to achieve the effect of cleaning the filter 4. The filter 4 can be cleaned without an additional electric drive device, thereby reducing the electricity cost.

[0038] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
