DETAILED DESCRIPTION

[0023] The special dust cover for an air inlet and outlet of a computer room air conditioner provided by the utility model will be described in detail in combination with the drawings and specific embodiments; meanwhile, it is explained here that, in order to make the embodiments more detailed, the following embodiments are preferred embodiments, and for some known technologies, other alternative ways can also be adopted by those skilled in the art.

[0024] For example, Figures 1 to 3As shown, the utility model discloses a kind of dust cover for air inlet and outlet of special machine room air conditioner, including main body 1, the middle part of main body 1 inside is fixedly connected with fixed frame 2, rotating shaft 3 is rotatably connected in the inside of fixed frame 2, rotating shaft 3 outside is located at the both ends of fixed frame 2 and is fixedly connected with rotating sleeve 4, the both sides of two rotating sleeves 4 are fixedly connected with filter plate 7 in the inside of main body 1, and collecting groove 9 is set in the position close to filter plate 7 in the both sides of two filter plates 7 at main body 1 bottom, collecting tank 10 is fixedly communicated with collecting groove 9 below in the bottom of main body 1, pulling box 11 is slidably connected in the inside of collecting tank 10, barrier plate 12 is fixedly connected with the both sides of two cleaning frames 8 in the inside of main body 1, ventilation groove is set in the inside of barrier plate 12, inclined plate is fixedly connected at the top of ventilation groove, and its lower end is inclined to cleaning frame 8, and a plurality of mounting blocks 13 are fixedly connected on the both sides of main body 1.

[0025] by mounting block 13, main body 1 is fixed in the air inlet and outlet of wall body, and its one side is aligned with machine room air conditioner, when machine room air conditioner is drawn, air enters from the other side of main body 1, is blocked by barrier plate 12 and is filtered by filter plate 7, and then air enters into machine room.

[0026] As Figures 1 to 4 As shown, rotating shaft 3 is fixedly connected with limit sleeve 6 on both sides, two limit sleeves 6 are rotatably connected in the inside of two filter plates 7 respectively, limit sleeve 6 is fixedly connected with cleaning frame 8 on the side away from rotating shaft 3, rotating assembly 5 is used to drive rotating shaft 3 to rotate, rotating assembly 5 is connected with rotating sleeve 4, rotating assembly 5 is fixedly connected on the outside of rotating sleeve 4, the number of rotating assembly 5 on the outside of same rotating sleeve 4 is eight, and is evenly distributed in ring shape, rotating assembly 5 includes fixed seat 501 connected with rotating sleeve 4, another end of fixed seat 501 is rotatably connected with fan blade 502, a plurality of air flow holes 503 are set in the inside of fan blade 502, which are evenly distributed, and the diameter is smaller and smaller close to fixed seat 501, baffle 504 is fixedly connected on the both sides of fan blade 502 at the top of fixed seat 501, and the included angle between baffle 504 and fan blade 502 is thirty degrees, brush is fixedly connected on the side close to corresponding filter plate 7 of cleaning frame 8, and brush is in close contact with corresponding filter plate 7.

[0027] When the air flows in the main body 1, it will blow the fan blades 502, causing it to rotate in the fixed seat 501, causing it to rotate thirty degrees toward the machine room, and then be blocked by the baffle 504. The air continues to flow, causing the fan blades 502 to drive the rotating sleeve 4 to rotate counterclockwise, and drive the limit sleeve 6 and the cleaning rack 8 to rotate together through the rotating shaft 3. As the cleaning rack 8 rotates, the brushes continuously brush the outer surfaces of the filter plates 7 on both sides, brushing off the attached dust. The brushed dust enters the collection box 10 along the collection groove 9, and the accumulated dust is conveniently handled through the pull-out box 11; when the machine room air conditioner is blowing, the air will blow the fan blades 502 to rotate thirty degrees away from the machine room, and then drive the rotating sleeve 4 to rotate counterclockwise, performing cleaning work synchronously.

[0028] When air circulates inside the main body 1, it will directly blow the fan blades 502. The rotation of the fan blades 502 is effectively transmitted to the rotating shaft 3 through the close connection between the fixed seat 501 and the rotating sleeve 4; the rotating shaft 3, as the transmission shaft of the entire system, its rotation drives the synchronous movement of the limiting sleeve 6, which not only ensures the close contact between the cleaning frame 8 and the filter plate 7, but also through its unique connection method, the rotational power of the rotating shaft 3 is smoothly transmitted to the cleaning frame 8, so that when the rotating shaft 3 rotates, the cleaning frame 8 will also rotate and start to clean the filter plate 7, so that the entire automatic cleaning process does not require any operation by the staff and does not require additional driving force. This design not only reduces maintenance costs, but also improves work efficiency.

[0029] A certain angle is formed between the baffle 504 and the fan blade 502, which not only helps to guide the direction of the airflow, but also can limit the rotation direction of the fan blade 502 by resisting the fan blade 502. When the fan blade 502 is impacted by airflow in different directions, the fan blade 502 can rotate in different directions. Whether it is the air intake or air exhaust process, the fan blade 502 can be guided by the baffle 504 to achieve angle adjustment and direction rotation. In this way, not only the waste of kinetic energy is avoided, but also the working efficiency of the drive component is improved, so that the fan blade 502 can be impacted by a more uniform airflow during rotation, so its rotation speed will also be more stable, which not only helps to improve the working efficiency of the entire dust cover device, but also can extend the service life of the fan blade 502 and reduce the failure rate caused by long-term wear.

[0030] In the above scheme, it should be noted that the air inlet and outlet dust covers in this application are used on the air conditioners in special machine rooms, and their purpose is to perform dust prevention when the air conditioners in special machine rooms are running.

[0031] The utility model discloses a working principle: through the installation block 13 with the main part 1 fixed in the air inlet and outlet of wall body, make its one side align the computer lab air conditioner, the computer lab air conditioner exhaust, air enters from the other side of main part 1, after the barrier 12 barrier and the filter of filter plate 7, filter, the larger sundries and dust are all blocked, and then air enters the computer lab, when air flows in the main part 1, it will blow the fan blade 502, makes it rotate in the fixed seat 501, makes it rotate thirty degrees to the computer lab direction, and then is blocked by the baffle 504, and air continues to flow, makes the fan blade 502 drive the rotating sleeve 4 counterclockwise rotation, and through the rotating shaft 3 drive the limiting sleeve 6 and the cleaning frame 8 rotate together, along with the rotation of cleaning frame 8, the brush constantly brushes the outside surface of both sides of filter plate 7, and the dust adhered is brushed, and the dust that is brushed is entered the collection box 10 along the collecting groove 9, and the dust that is accumulated is conveniently handled through the pull box 11, when the computer lab air conditioner blows, air will blow the fan blade 502 and rotate thirty degrees to the direction away from the computer lab, and then drive the rotating sleeve 4 counterclockwise rotation, and the synchronous cleaning work is carried out.

[0032] The utility model covers any alternative, modification, equivalent method and scheme made on the essence and range of the utility model, in order to make the public have the thorough understanding of the utility model, the specific details have been explained in the above preferred embodiment of the utility model, and the utility model can also be completely understood without the description of these details to the person skilled in the art.

[0033] The above only is the preferred implementation mode of the utility model, and it should be pointed out that for ordinary skilled person in the art, on the premise of not departing from the principle of the utility model, can also make a number of improvements and refinements, and these improvements and refinements also should be regarded as the protection range of the utility model.
