Description

Technical Field

[0001] The present invention relates to the field of air purification, and in particular to a dust filtering and ventilation device for a communication base station room. Background Art

[0002] Dust filtration and ventilation in communication base station rooms are important measures to ensure the normal operation of base station equipment and extend the life of the equipment. The importance of dust filtration and ventilation is as follows:

[0003] Protecting equipment: Base station rooms are densely populated with equipment, requiring high air quality. A dust-filtering ventilation system effectively filters dust, particulate matter, and other impurities from the air, reducing dust accumulation on equipment and lowering the risk of dust-related equipment failures.

[0004] Improve energy efficiency: Through reasonable ventilation design, the temperature in the computer room can be lowered, the energy consumption of air conditioners and other refrigeration equipment can be reduced, and the overall energy efficiency can be improved.

[0005] Extend equipment life: A good ventilation environment helps reduce equipment temperature and reduce the impact of thermal stress on the equipment, thereby extending the service life of the equipment.

[0006] In short, dust filtration and ventilation in communication base station equipment rooms are crucial for ensuring the normal operation of base station equipment and extending its lifespan. A properly designed dust filtration and ventilation system can effectively improve air quality within the equipment room, reduce equipment failure rates, increase energy efficiency, and extend equipment lifespan. In practice, a rational design should be tailored to the equipment layout and heat dissipation requirements within the equipment room, and high-efficiency filtration devices and energy-efficient, environmentally friendly ventilation equipment should be selected to ensure stable system operation and meet energy-saving and environmental protection requirements.

[0007] A Chinese patent document with authorization announcement number CN216677505U discloses a dust filtering and ventilation device for a communication base station room, comprising a shell, a mounting plate installed at one end of the outer side of the water tank by screws, a slide groove being opened on one end face of the mounting plate, a tension spring being welded to the bottom face of the slide groove, a slider being welded to one end of the tension spring, a filter frame being installed to one end of the slider by screws, reset springs being welded to both ends of the top face of the inside of the water tank, the bottom ends of the two reset springs being connected by a push plate, a driving plate being fixedly installed on the top face of the push plate at the position of the air outlet pipe, and a rotating blade being movably installed inside the air outlet pipe.

[0008] The aforementioned dust filtration and ventilation devices for communication base station rooms have the following drawbacks: They operate in a single direction and angle, purifying only the air surrounding their installation location. Consequently, the air purification range is limited, the air purification path is fixed, and the distance from the equipment within the communication base station room is long, resulting in low purification efficiency. Furthermore, they cannot provide targeted dust filtration and ventilation for specific areas. However, base station rooms are densely populated with equipment and require high air quality, and existing devices clearly cannot meet these requirements. Summary of the Invention

[0009] In response to the problems existing in the background technology, a dust filtration and ventilation device for a communication base station room is proposed. By rotating the rotating box and the rotating inner frame, and then coordinating the telescopic dust filter to extend and retract, on the one hand, the direction and angle of ventilation can be changed, and on the other hand, the two sets of dust filter components can be connected to the ventilation duct, ultimately realizing the switching of the air purification path and space, and meeting the targeted dust filtration and ventilation needs of the communication base station room.

[0010] The present invention provides a dust filtration and ventilation device for a communication base station room, comprising a fixed outer frame, multiple sets of ventilation ducts, a rotating inner frame, a rotating box, two sets of dust filtration components, and a ventilation fan.

[0011] The two sets of dust filter components retract and move synchronously with the rotation of the rotating box and the rotating inner frame until they are respectively connected to the inside and outside of the communication base station room or connected to the ventilation ducts on the corresponding sides, thereby adjusting the dust filter ventilation position to switch the air purification path and space.

[0012] Preferably, the rotating inner frame includes a frame body whose side walls are penetrated by through hole 2; openings for the dust filter assembly to extend out are provided at the front and rear ends of the frame body; the second installation cavity is located in the frame body and is connected to the opening; the frame body is connected to the fixed outer frame through the rotation of the driving structure origin, so that through hole 1 and through hole 2 are connected or staggered.

[0013] Preferably, the rotating box includes a box body; the box body is rotatably arranged in the second installation cavity, and a ventilation chamber is arranged inside; the installation port is located on both sides of the ventilation chamber, for two sets of dust filter components to be installed through; the ventilation fan is located in the ventilation chamber, and a circle of drying parts is arranged on the outer periphery.

[0014] Preferably, the dust filter assembly includes a fixed mounting sleeve located inside the mounting port, a movable mounting sleeve located outside the mounting port, and a telescopic dust filter located between the fixed mounting sleeve and the movable mounting sleeve; the movable mounting sleeve drives the telescopic dust filter to extend and retract by moving horizontally outside the mounting port.

[0015] Preferably, the telescopic dust filter comprises a telescopic ring connecting the fixed mounting sleeve and the movable mounting sleeve; multiple layers of filter screens are arranged at intervals in the telescopic ring.

[0016] Preferably, the filter screen includes front and rear air permeable layers and a mesh layer located between the front and rear air permeable layers; multiple groups of filter membranes are arranged in the mesh layer to cross form a diamond grid, and when the front and rear air permeable layers are subjected to force, the diamond grids are deformed synchronously.

[0017] Preferably, a vibrator extending out of the box body is provided on the fixed installation sleeve; and a vibration groove opposite to the vibrator is provided on the movable installation sleeve.

[0018] Preferably, two groups of ventilation pipes are provided, one on each side of the fixed outer frame.

[0020] Preferably, the ventilation pipe includes a rotating sleeve; one end of the pipe is rotatably connected to the through hole 1 through the rotating sleeve, and the other end is provided with a ventilation cover.

[0021] Compared with the prior art, the present invention has the following beneficial technical effects: the rotating box and the rotating inner frame are arranged to rotate, so that the two groups of dust filter components can rotate 360 ​​degrees, and then the telescopic dust filter can be extended and retracted. On the one hand, the direction and angle of ventilation can be changed, and the range of purified air can be flexibly adjusted. On the other hand, the installation port, through hole 1, and through hole 2 can be selectively connected, and then the two groups of dust filter components are connected to the ventilation pipe.

They can all be installed in the communication base station room, or they can be installed inside and outside the communication base station room respectively, ultimately achieving the switching of air purification paths and spaces, meeting the needs of targeted dust filtration and ventilation in the communication base station room. Because the telescopic dust filter is retractable, not only can the structural volume and filtration position be adjusted, but also the movable installation sleeve and the fixed installation sleeve can be fitted together to compress the diamond grid to achieve the maximum deformation, the vibrator and the vibration groove cooperate, and the rotating box and the rotating inner frame rotate, ultimately accelerating the movement of dust and ensuring its dust filtration performance. The device has a good air purification effect in the communication base station room, strong targeting, diverse working modes, and stable and long-lasting purification performance.

[0034] Example 1, as Figures 1-6 As shown, the present invention proposes a dust filtering and ventilation device for a communication base station room, comprising a fixed outer frame 1, multiple sets of ventilation ducts 2, a rotating inner frame 3, a rotating box 4, two sets of dust filter 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 provided in the center and a through hole 101 provided on the side wall to connect to the mounting cavity 1; one end of the ventilation duct 2 is connected to the through hole 101, and the other end extends to a designated position inside or outside the communication base station room; the rotating inner frame 3 is rotatably arranged in the mounting cavity 1, with a mounting cavity 2 provided inside, and a through hole 2 301 provided on the side wall to connect to the mounting cavity 2; the rotating box 4 is rotatably arranged in the mounting cavity 2, with the rotation direction intersecting with the rotating inner frame 3, and both ends extending out of the rotating inner frame 3; the two sets of dust filter 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 between the two sets of dust filter components 5.

[0035] 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 connected to the ventilation pipes 2 on the corresponding sides, thereby realizing the regulation of the dust filter ventilation position to switch the air purification path and space.

[0036] like Figure 5 As shown, the rotating inner frame 3 includes a frame body 302 with a second through-hole 301 extending through its sidewalls. The front and rear ends of the frame body 302 are provided with openings for the dust filter assembly 5 to extend outward. The second mounting cavity is located within the frame body 302 and communicates with the opening. The frame body 302 is connected to the fixed outer frame 1 by rotating the drive mechanism at its origin, so that the first through-hole 101 and the second through-hole 301 are connected or interlaced.

[0037] It should be further explained that the frame 302 is a cylindrical structure and can rotate 360 ​​degrees along a vertical plane.

[0038] It needs to be further explained that, 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 set on the mounting ring 303; a motor 1 and a gear 102 driven to rotate by the motor 1 are set on the fixed outer frame 1; the gear 102 is engaged with the gear ring 304 to drive the frame 302 to rotate.

[0039] By rotating the frame body 302 at its origin to connect and fix the outer frame 1, on the one hand, the connection or interlacing of through hole 101 and 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 filter components 5 can be adjusted to increase the range of air purification.

[0040] 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, respectively for two sets of dust filter components 5 to be 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.

[0041] It should be further explained that the box body 401 is set to be waist-shaped, the side corresponding to the installation port 402 is set to be flat, and the two sides of the installation port 402 are set to be arc-shaped surfaces. It is driven by motor 2 404 and rotates 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.

[0042] It should be further explained that the box 401 can rotate 360 ​​degrees along the horizontal plane.

[0043] The drying element 403 is a tube-shaped element that is electrically heated and is used to dry the air entering the communication base station room.

[0044] like Figure 7-Figure 8As shown, the dust filter assembly 5 comprises a fixed mounting sleeve 501 located within the mounting opening 402, a movable mounting sleeve 502 located outside the mounting opening 402, and a telescopic dust filter element located between the fixed mounting sleeve 501 and the movable mounting sleeve 502. The movable mounting sleeve 502 is driven by a cylinder 503, moving horizontally outside the mounting opening 402, thereby extending and retracting the telescopic dust filter element. This retraction and expansion of the telescopic dust filter element not only adjusts the range of air purification but also allows the internal dust filter structure to move, facilitating dust removal.

[0045] 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 .

[0046] It should be further explained that a tear-off base 506 is attached to the bottom of the expansion ring 504. By removing the tear-off base 506, the bottom of the multi-layer filter 505 can be exposed, thereby draining the dust between the filters 505. The tear-off base 506 is fixed to the edge of the filter 505 by gluing to form a seal.

[0047] By moving the mounting sleeve 502 to drive the expansion 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 movable, thereby facilitating the falling of dust.

[0048] It needs to be further explained that, Figure 9 As shown, the filter screen 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 form a diamond grid. When the front and rear air permeable layers 50501 are subjected to force, the diamond grids deform synchronously.

[0049] That is to say, by moving the mounting sleeve 502 to drive the telescopic ring 504 to expand and contract, the spacing between the multiple layers of filter screens 505 changes, adjacent filter screens 505 are squeezed, and the diamond grids are deformed synchronously, thereby accelerating the movement of dust.

[0050] It needs to be further explained that, Figure 10 As shown, a vibrator 507 extending out of the box 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;

[0051] It should be further explained that multiple groups of vibrators 507 are arranged at equal intervals along the mounting opening 402 .

[0052] When the movable sleeve 502 drives the expansion ring 504 to expand and contract until the movable sleeve 502 and the fixed sleeve 501 fit together, the diamond grid reaches its maximum deformation. The vibrator 507 extends into the vibration groove 508, and the movable sleeve 502 and the fixed sleeve 501 vibrate synchronously, accelerating the movement of dust.

[0053] Example 2: Based on the dust filtering and ventilation device of a communication base station room in Example 1, this example proposes a ventilation pipe 2 structure as follows: Figure 1-Figure 2 As shown, two sets of ventilation ducts 2 are provided, one on each side of the fixed external frame 1, enabling dust filtration and ventilation from both sides. Ventilation ducts 2 include a rotating sleeve 201. One end of a duct 202 is connected to through-hole 101 via the rotating sleeve 201, and a ventilation hood 203 is provided at the other end. Ducts 202 are bendable and retractable, with the length and curvature adjustable as needed for targeted dust filtration and ventilation. A slag screen 204 is installed within the ventilation hood 203 to prevent debris from entering duct 202.

[0054] The two sets of ventilation pipes 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 pipes 2.

[0055] Example 3, based on a dust filtering and ventilation device for a communication base station room in Example 1, this example proposes a ventilation pipe 2 structure as follows Figure 11 As shown, four sets of ventilation pipes 2 are provided, located around the fixed external frame 1, enabling dust filtering and ventilation from all sides. The ventilation pipes 2 include a rotating sleeve 201. One end of the pipe 202 is connected to the through-hole 101 via the rotating sleeve 201, and the other end is provided with a ventilation hood 203. The pipes 202 are bendable and retractable, with the length and curvature adjustable as needed for targeted dust filtering and ventilation. A slag screen 204 is installed within the ventilation hood 203 to prevent debris from entering the pipe 202.

[0056] 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 connected alternately to purify the air from different positions.

[0057] Example 4: Based on the dust filtration and ventilation device of a communication base station room in Example 1, this example proposes a dust filtration and ventilation method for a communication base station room. The specific steps are as follows:

[0058] S1. Drill a hole in the wall of the communication base station room and install the fixed external frame 1 on the hole;

[0059] S2. Multiple sets of ventilation pipes 2 are installed and positioned according to needs. They can all be installed in the communication base station room, or they can be installed inside and outside the communication base station room respectively. The internal ventilation end can be close to the host or other machines;

[0060] S3, the ventilation fan 6 is started, and air begins to circulate inside and outside the communication base station room;

[0061] S4, the two sets of dust filter components 5 rotate 360 ​​degrees with the rotation of the rotating box 4 and the rotating inner frame 3, and cooperate with the telescopic dust filter to flexibly adjust the range of air purification;

[0062] S5. The air outside the communication base station room is filtered step by step through the multi-layer filter screen 505 of the external dust filter assembly 5, heated and dried by the drying element 403 after entering the ventilation chamber, and then enters the multi-layer filter screen 505 of the internal dust filter assembly 5 for secondary filtration before finally entering the communication base station room.

[0063] S6. 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 extended, the installation port 402, the through hole 101, and the through hole 2 301 are connected, and the ventilation pipe 2 is opened;

[0064] 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 installed inside and outside the communication base station room respectively, 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;

[0065] S8. After working for a period of time, the movable installation sleeve 502 drives the telescopic ring 504 to extend and retract until the movable installation sleeve 502 and the fixed installation sleeve 501 are in contact with each other. At this time, the diamond grid reaches its maximum deformation. The vibrator 507 extends into the vibration groove 508. The movable installation sleeve 502 and the fixed installation sleeve 501 vibrate synchronously. The rotating box 4 and the rotating inner frame 3 rotate to accelerate the movement of dust.

[0066] S9. Remove the tear-off bottom 506 to expose the bottom of the multi-layer filter 505 and remove the dust between the filters 505.

[0067] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
