When gas passes through the air inlet 2 and the air outlet 3, it can blow the mounting plate 12 and the filter plate 13. When the mounting plate 12 and the filter plate 13 move forward and backward, they press the first positioning plate 7 and the second positioning plate 11 on the front and rear sides respectively. The first hydraulic rod 5 and the first spring 6 reduce the vibration of the movement of the first positioning plate 7, and the second hydraulic rod 9 and the second spring 10 reduce the vibration of the movement of the second positioning plate 11, thereby preventing the filter plate 13 from filtering and vibrating under the blowing of air and generating noise;

[0027] Inserts 14 are fixedly welded on the upper and lower sides of the revolving door 8. Insert grooves 15 are provided on the outside of the air inlet 2 and the air outlet 3, which are interference fit with the inserts 14.

[0028] A mounting bracket 16 is fixedly welded inside the air inlet 2. A first motor 17 is mounted on the upper flange of the mounting bracket 16. The power end coupling of the first motor 17 is connected to an air bleed fan 18. The first motor 17 drives the air bleed fan 18, so that air enters the air inlet 2 and is discharged from the air outlet 3 after heat dissipation.

[0029] A first connecting frame 20 is fixedly welded to both sides of the front of the filter plate 13, a first lifting rod 21 is fixedly welded inside the first connecting frame 20, a first lifting plate 22 is slidably mounted on the outside of the first lifting rod 21, a first threaded rod 23 is threadedly mounted on the middle part of the first lifting plate 22, a scraper 24 is rotatably mounted on the tail of the first threaded rod 23, sliding rods 25 are fixedly welded on both sides of the scraper 24, the sliding rods 25 are slidably connected to the outside of the first lifting plate 22, the filter plate 13 is driven up and down along the first lifting rod 21 by the first threaded rod 23, so that the scraper 24 cleans the dust on the outside of the filter plate 13, the cleaning effect of the scraper 24 can be improved by spraying water on the filter plate 13, and by rotating the first threaded rod 23, the first lifting rod 21 drives the scraper 24 to be close to the filter plate 13, which can also improve the cleaning effect;

[0030] A blanking plate 19 is rotatably mounted below the air inlet 2 and the air outlet 3. By opening the blanking plate 19, dust can fall from the blanking plate 19.

[0031] The mounting plate 12 is provided with four sets of movable grooves 30 on the upper and lower sides, and a sliding groove 26 communicating with the movable groove 30 is provided inside the mounting plate 12. A sliding piece 28 is slidably installed inside the sliding groove 26. A sliding rod 25 is fixedly welded on one side of the sliding piece 28. The sliding rod 25 penetrates into the movable groove 30 and is fixedly welded with a connecting plate 31. Locking plates 32 are fixedly welded on both sides of the connecting plate 31. A third spring 29 is fixedly welded between the sliding piece 28 and the sliding groove 26. The third spring 29 is sleeved on the outside of the sliding rod 25. Under normal tension of the third spring 29, the sliding piece 28 can be pulled to make the sliding rod 25 drive the connecting plate 31 and the locking plate 32 to move away from the sliding groove 26. A connecting groove 33 communicating with the sliding groove 26 is provided on the front side of the mounting plate 12. A pulling plate 34 is fixedly welded on one end of the sliding piece 28. The pulling plate 34 is slidably installed inside the connecting groove 33. The movable plate 34 can control the movement of the sliding piece 28 and ensure that the distance between the pulling plates 34 on both sides is equivalent to the width of a human palm, so that one hand can control the movement of the two sets of pulling plates 34 at the same time, and can drive the mounting plate 12 to be inserted into the mounting groove 4 by the pulling plate 34. The first positioning plate 7 and the second positioning plate 11 are provided with an insertion groove 44 that is interference fit with the locking plate 32. The first positioning plate 7 and the second positioning plate 11 are provided with a locking groove 45 that communicates with the insertion groove 44. By inserting the locking plates 32 on the front and rear sides along the insertion groove 44 to one side of the locking groove 45, when the third spring 29 pulls the sliding piece 28, the locking plate 32 is inserted into the locking groove 45, thereby ensuring that the mounting plate 12 is connected to the first positioning plate 7 and the second positioning plate 11, thereby ensuring that the mounting plate 12 can drive the first positioning plate 7 and the second positioning plate 11 to vibrate when they are in motion, thereby improving the vibration reduction efficiency;

[0032] An isolation plate 35 is fixedly welded inside the power box 1. Several groups of gas outlets 36 are fixedly welded on one side of the isolation plate 35. The gas enters between the air inlet 2 and the isolation plate 35, and then passes through the gas outlets 36 and blows from one side and the top to the internal components of the power supply host.

[0033] A second connecting frame 37 is fixedly welded on the front and back sides of the power box 1, a second lifting rod 39 is fixedly welded between the rear second connecting frame 37 and the isolation plate 35, a second lifting plate 40 is slidably installed on the outside of the second lifting rod 39, a second threaded rod 38 is installed on the other end of the second lifting plate 40, and the two ends of the second threaded rod 38 are rotatably connected to the second connecting frame 37 and the isolation plate 35 respectively, a plurality of second motors 42 are installed on the outer flange of the second connecting frame 37, the power end of the second motor 42 is fixedly welded to one end of the second threaded rod 38, and the second lifting plate 40 is fixedly welded to the second lifting plate 40. A plug 41 is fixedly welded at the end thereof for fitting with the air outlet 36. Each component in the power supply box 1 is equipped with a temperature sensor. When the temperature sensor senses that the temperature at a particular position is too high, the second motor 42 drives the second threaded rod 38, driving the second lifting plate 40 to move along the second lifting rod 39, thereby inserting the plug 41 into the air outlet 36. The plug 41 adopts a rubber structure with a certain degree of compressibility, ensuring that the air outlet 36 is completely sealed and the air outlet 36 of the overheated part is kept open, thereby improving the heat dissipation efficiency of the overheated part by increasing the air flow rate;

[0034] A wire hole 43 is formed at one end of the isolation plate 35 and the second connecting frame 37 , so that the temperature sensor can be electrically connected to the second motor 42 through the wire hole 43 .

[0035] Working principle: When the invention is in use, the mounting plate 12 and the filter plate 13 are installed in the mounting groove 4 so that one side is close to the first positioning plate 7, the rotating door 8 is rotated, and the rotating door 8 is closed, so that the second positioning plate 11 is close to both sides of the mounting plate 12, and the sliding piece 28 is driven to move by the pulling plate 34, so that the locking plate 32 is opposite to the insertion groove 44 and enters one side of the locking groove 45. The third spring 29 pulls the sliding piece 28, and the connecting rod 27 drives the connecting plate 31 and the locking plate 32 to move, so that the locking plate 32 is inserted into the locking groove 45, so that the mounting plate 12 and the second positioning plate 11 are close to each other. The first positioning plate 7 and the second positioning plate 11 are connected. The first motor 17 drives the induced air fan 18, so that the air enters from the air inlet 2 and is discharged from the air outlet 3, which can blow the mounting plate 12 and the filter plate 13. When the mounting plate 12 and the filter plate 13 move forward and backward, they compress and stretch the first positioning plate 7 and the second positioning plate 11 on the front and rear sides respectively. The first hydraulic rod 5 and the first spring 6 reduce the vibration of the movement of the first positioning plate 7. The second hydraulic rod 9 and the second spring 10 reduce the vibration of the movement of the second positioning plate 11, thereby preventing the filter plate 13 from filtering and vibrating and generating noise under the blowing of air;

[0036] The gas enters between the air inlet 2 and the isolation plate 35, and is then blown from one side and the top to the internal components of the power supply host through the air outlet 36. The components in the power box 1 are equipped with temperature sensors. When the temperature sensor senses that the temperature at a certain specific position is too high, the second motor 42 drives the second threaded rod 38, driving the second lifting plate 40 to move along the second lifting rod 39, so that the plug 41 is inserted into the air outlet 36, and the air outlet 36 of the overheating part is kept open, thereby improving the heat dissipation efficiency of the overheating part by increasing the air flow rate.
