[0002] Dust filtration and ventilation in the communication base station room is an important measure to ensure the normal operation of the base station equipment and extend the life of the equipment. The importance of dust filtration and ventilation is as follows: Protect equipment: The base station room is densely populated with equipment and has high requirements for air quality. The dust filtration ventilation system can effectively filter dust, particles and other impurities in the air, reduce dust accumulation on equipment, and reduce the equipment failure rate caused by dust.

[0004] Extend equipment life: A good ventilation environment helps lower equipment temperature and reduce the impact of thermal stress on the equipment, thereby extending the service life of the equipment.

[0005] In short, dust filtration and ventilation in the communication base station room is an important measure to ensure the normal operation of base station equipment and extend the life of equipment. By rationally designing the dust filtration and ventilation system, the air quality in the room can be effectively improved, the equipment failure rate can be reduced, energy efficiency can be improved, and the service life of equipment can be extended.

[0023] Embodiment 1, as Figure 1-Figure 6 As shown, a dust filtering and ventilation device for a communication base station room proposed by the present invention comprises a fixed outer frame 1, multiple groups of ventilation pipes 2, a rotating inner frame 3, a rotating box 4, two groups of dust filtering components 5 and a ventilation fan 6. The fixed outer frame 1 is installed through the wall of the communication base station room, with a mounting cavity 1 arranged in the center, and a through hole 101 connected to the mounting cavity 1 arranged on the side wall; one end of the ventilation pipe 2 is connected to the through hole 101, and the other end extends to a position inside and outside the communication base station room; the rotating inner frame 3 is rotatably arranged in the mounting cavity 1, with a mounting cavity 2 arranged inside, and a through hole 2 301 connected to the mounting cavity 2 arranged on the side wall; the rotating box 4 is rotatably arranged in the mounting cavity 2, with the rotation direction interlaced with the rotating inner frame 3, and both ends extend out of the rotating inner frame 3; the two groups of dust filtering components 5 are respectively located at the two ends of the rotating box 4; the ventilation fan 6 is located in the rotating box 4, and is located between the two groups of dust filtering components 5.

[0024] The two groups of dust filter components 5 are synchronously extended and moved with the rotation of the rotating box 4 and the rotating inner frame 3 until they are respectively connected to the inside and outside of the communication base station room or respectively connected to the ventilation pipes 2 on the corresponding sides, so as to adjust the dust filter ventilation position and switch the air purification path and space.

[0025] like Figure 5As shown, the rotating inner frame 3 includes a frame body 302 whose side wall is penetrated by the second through hole 301; the front and rear ends of the frame body 302 are provided with openings for the dust filter assembly 5 to extend out; the second installation cavity is located in the frame body 302 and communicates with the opening. The frame body 302 is connected to the fixed outer frame 1 by rotating the driving structure origin, so that the first through hole 101 and the second through hole 301 are connected or staggered.

[0026] It should be further explained that the frame 302 is a cylindrical structure and can rotate 360 ​​degrees along a vertical plane.

[0027] It needs to be further explained that if Figure 6 As shown, the driving structure includes a mounting ring 303 sleeved on the outer periphery of the frame 302; a gear ring 304 is arranged on the mounting ring 303; a motor 1 and a gear 102 driven to rotate by the motor 1 are arranged on the fixed outer frame 1; the gear 102 is meshed with the gear ring 304 to drive the frame 302 to rotate.

[0028] By rotating the frame body 302 at the origin to connect the fixed outer frame 1, on the one hand, the connection or staggering of the through hole 101 and the through hole 2 301 can be controlled, that is, the opening and closing of the ventilation pipe 2 can be adjusted; on the other hand, the dust filtering and ventilation directions of the two groups of dust filtering components 5 can be adjusted to increase the range of air purification.

[0029] like Figure 6 As shown, the rotating box 4 includes a box body 401; the box body 401 is rotatably set in the installation cavity 2, and a ventilation chamber is set inside; the installation port 402 is located on both sides of the ventilation chamber, and two sets of dust filter components 5 are respectively installed through; the ventilation fan 6 is located in the ventilation chamber, and a circle of drying parts 403 is set on the outer periphery.

[0030] It should be further explained that the box body 401 is configured to be waist-shaped, the side corresponding to the installation port 402 is configured to be a plane, and the two sides of the installation port 402 are configured to be arc-shaped surfaces, and it is driven by the second motor 404 to rotate along the origin of the inner wall of the second installation cavity, so that the installation port 402 is connected or staggered with the second through hole 301.

[0031] It should be further explained that the box 401 can rotate 360 ​​degrees along the horizontal plane.

[0032] The drying element 403 is a tube-shaped element that is electrically heated and is used to dry the air entering the room of the communication base station.

[0033] like Figure 7-Figure 8As shown, the dust filter assembly 5 includes a fixed installation sleeve 501 located inside the installation port 402, a movable installation sleeve 502 located outside the installation port 402, and a telescopic dust filter located between the fixed installation sleeve 501 and the movable installation sleeve 502. The movable installation sleeve 502 is driven by a cylinder 503 to move horizontally outside the installation port 402, driving the telescopic dust filter to extend and retract. The telescopic dust filter can adjust the range of purified air on the one hand, and make the internal dust filter structure movable on the other hand, which is conducive to removing dust.

[0034] It should be further explained that the telescopic dust filter comprises a telescopic ring 504 connecting the fixed installation sleeve 501 and the movable installation sleeve 502 ; multiple layers of filter screens 505 are arranged at intervals in the telescopic ring 504 .

[0035] It should be further explained that a tear-off bottom 506 is attached to the bottom of the expansion ring 504. By removing the tear-off bottom 506, the bottom of the multi-layer filter 505 can be exposed, thereby guiding out the dust between the filter 505. The tear-off bottom 506 and the edge of the filter 505 are fixed by adhesion to form a seal.

[0036] By moving the installation sleeve 502 to drive the telescopic ring 504 to expand and contract, the spacing between the multiple layers of filter screens 505 changes, and adjacent filter screens 505 are squeezed to make the screen surface move, thereby facilitating the falling of dust.

[0037] It needs to be further explained that if Fig. 9 As shown, the filter net 505 includes front and rear air permeable layers 50501 and a mesh layer 50502 located between the front and rear air permeable layers 50501. Multiple groups of filter membranes are arranged in the mesh layer 50502 to cross and form a diamond grid. When the front and rear air permeable layers 50501 are subjected to force, the diamond grids are deformed synchronously.

[0038] That is to say, the telescopic ring 504 is extended and retracted by moving the installation sleeve 502, the spacing between the multi-layer filter screens 505 changes, the adjacent filter screens 505 are squeezed, and the diamond grids are deformed synchronously, thereby accelerating the movement of dust.

[0039] It needs to be further explained that if Fig.10 As shown, a vibrator 507 extending out of the box body 401 is provided on the fixed installation sleeve 501; a vibration groove 508 opposite to the vibrator 507 is provided on the movable installation sleeve 502; It should be further explained that a plurality of groups of vibrators 507 are arranged at equal intervals along the mounting opening 402 .

[0040] When the movable installation sleeve 502 drives the telescopic ring 504 to extend until the movable installation sleeve 502 and the fixed installation sleeve 501 fit together, the diamond grid reaches the maximum deformation. The vibrator 507 extends into the vibration groove 508, and the movable installation sleeve 502 and the fixed installation sleeve 501 vibrate synchronously to accelerate the movement of dust.

[0041] Embodiment 2, based on a dust filtering and ventilation device for a communication base station room in Embodiment 1, this embodiment proposes a ventilation pipe 2 structure as follows Figure 1-Figure 2 As shown, two groups of ventilation pipes 2 are provided, which are respectively located on both sides of the fixed outer frame 1, so that dust filtering and ventilation can be performed from both sides.

[0042] The two groups of ventilation ducts 2 in this embodiment can purify the air on both sides of the base station room, which can be the left and right sides or the upper and lower sides, depending on the installation position of the ventilation ducts 2.

[0043] Embodiment 3, based on a dust filtering and ventilation device for a communication base station room in Embodiment 1, this embodiment proposes a ventilation pipe 2 structure as follows Fig.11 As shown, four groups of ventilation pipes 2 are arranged, which are respectively located around the fixed outer frame 1, and dust filtering and ventilation can be performed from all sides.

[0044] The four groups of ventilation ducts 2 in this embodiment can purify the air around the base station room. The ventilation ducts 2 at different positions can be switched as needed, for example, the ventilation ducts 2 on the upper and lower sides and the ventilation ducts 2 on the left and right sides can be alternately connected to purify the air from different positions.

When the air purification path and space need to be switched and the air purification position is adjusted, the rotating box 4 and the rotating inner frame 3 rotate, the telescopic dust filter is shortened, the installation port 402, the through hole 101, and the through hole 2 301 are connected, and the ventilation pipe 2 is opened; S7, the ventilation fan 6 is started, and the air begins to circulate inside and outside the communication base station room or inside the communication base station room: when multiple sets of ventilation pipes 2 are respectively installed inside and outside the communication base station room, targeted internal and external air circulation can be achieved; when multiple sets of ventilation pipes 2 are all installed in the communication base station room, purification of the internal air can be achieved; S8, after working for a period of time, the mobile installation sleeve 502 drives the telescopic ring 504 to extend until the mobile installation sleeve 502 and the fixed installation sleeve 501 fit together, and at this time the diamond grid reaches the maximum deformation; the vibrator 507 extends into the vibration groove 508, the mobile installation sleeve 502 and the fixed installation sleeve 501 vibrate synchronously, the rotating box 4 and the rotating inner frame 3 rotate, and the movement of dust is accelerated; S9.
