Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of servers, and in particular to a dustproof device and a server cabinet. BACKGROUND

[0002] The server cabinet needs to continuously ensure efficient ventilation and heat dissipation. The existing technology usually adopts an open ventilation port or a static dust filter plate scheme. The former forms an unobstructed ventilation channel, but causes the long drive of external dust, resulting in dust accumulation, local overheating and stability degradation of internal electronic components of the server. The latter can intercept large-particle pollutants, but the pores of the dust filter plate are gradually blocked due to dust deposition in long-term use, resulting in an exponential increase in air flow resistance and a cliff-like decay of heat dissipation efficiency. In extreme conditions, it will trigger the server to overheat and shut down.

[0003] The open ventilation port sacrifices the dustproof safety of the equipment to maintain the short-term heat dissipation capacity, and the static dust filter plate is forced to bear the irreversible decay of the heat dissipation performance in exchange for temporary protection effect. The mutual exclusivity of dustproof and heat dissipation functions makes the existing technology unable to meet the complex needs of long-term clean operation environment and continuous efficient heat dissipation capacity of the server room.

[0004] Therefore, it is urgent to develop a dustproof device and a server cabinet with dynamic adjustment of ventilation cross-sectional area and self-cleaning capacity to block dust invasion while maintaining the sustainable smoothness of the heat dissipation channel. SUMMARY

[0005] The present application provides a dustproof device and a server cabinet to at least solve the problem of dust blockage in the server cabinet with a dust filter plate in the related art during long-term use.

[0006] The present application provides a dustproof device, which comprises a dust filter plate, a plurality of dustproof plates, a plurality of driving assemblies, a cleaning assembly, and a plurality of linkage assemblies. The dust filter plate is arranged at a ventilation port of a cabinet. The dust filter plate has a plurality of rows of air inlet hole groups arranged at intervals in a first direction. Each row of air inlet hole groups comprises a plurality of air inlet holes arranged at intervals in a second direction perpendicular to the first direction. The plurality of dustproof plates are arranged on a first side of the dust filter plate corresponding to the plurality of rows of air inlet hole groups and are rotatable about an axis parallel to the second direction. The plurality of driving assemblies are arranged on the dust filter plate and drive the plurality of dustproof plates to rotate to adjust the opening angle of the plurality of dustproof plates relative to the dust filter plate. The cleaning assembly is arranged on a second side of the dust filter plate. The cleaning assembly comprises a plurality of movable cleaning members. The plurality of linkage assemblies drive the plurality of cleaning members to pass through the plurality of air inlet holes to realize cleaning in response to the rotation of the plurality of dustproof plates.

[0007] The present invention also provides a server cabinet, comprising a cabinet body, wherein the side wall of at least one side of the cabinet body is provided with a plurality of ventilation openings spaced apart and distributed along the height direction of the cabinet body; and the plurality of dustproof devices are respectively provided at the ventilation openings.

[0008] This invention achieves the coordinated operation of dust prevention and self-cleaning functions through a linkage component. Multiple rows of independently controllable dust shields adjust the opening and closing angles according to actual needs, ensuring the cabinet's ventilation and heat dissipation requirements while effectively blocking dust ingress. Secondly, a linkage component automatically triggers the cleaning action of the cleaning component while the dust shield rotates to adjust the ventilation volume, allowing the cleaning components to pass through the corresponding air inlets for real-time dust removal, resolving the technical problem of traditional dust prevention devices being prone to dust accumulation and clogging. This not only extends the service life of the dust filter, but also reduces the frequency of manual maintenance, enabling intelligent and automated operation of the dust prevention system.

[0068] In order for those skilled in the art to better understand the technical scheme of the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0069] Figure 1 A perspective view of a server cabinet according to an embodiment of the present application is shown in FIG. 1. Figure 2 A perspective view of a dustproof device according to an embodiment of the present application is shown in FIG. 2. Figure 3 A partial view of a dustproof device according to an embodiment of the present application is shown in FIG. 3.

[0070] An embodiment of the present application provides a dustproof device, as shown in Figures 1 to 3As shown, the dustproof device comprises a filter plate 1, a plurality of dustproof plates 2, a plurality of driving assemblies 3, a cleaning assembly 4 and a plurality of linkage assemblies 5. The filter plate 1 is arranged at the air inlet of the cabinet, and the filter plate 1 has a plurality of rows of air inlet hole groups arranged at intervals in a first direction, each row of air inlet hole groups comprising a plurality of air inlet holes 11 arranged at intervals in a second direction perpendicular to the first direction; the plurality of dustproof plates 2 are arranged on the first side of the filter plate 1 corresponding to the plurality of rows of air inlet hole groups, and are respectively rotatable about an axis parallel to the second direction; the plurality of driving assemblies 3 are arranged on the filter plate 1 and respectively drive the plurality of dustproof plates 2 to rotate to adjust the opening angle of the plurality of dustproof plates 2 relative to the filter plate 1; the cleaning assembly 4 is arranged on the second side of the filter plate 1, and the cleaning assembly 4 comprises a plurality of movable cleaning members 41; the plurality of linkage assemblies 5 respectively drive the plurality of cleaning members 41 to pass through the plurality of air inlet holes 11 to achieve cleaning in response to the rotation of the plurality of dustproof plates 2.

[0071] According to an embodiment of the present application, the first direction is configured as the width direction of the filter plate 1 (i.e. the transverse dimension direction of the filter plate 1), and the second direction perpendicular thereto corresponds to the length direction of the filter plate 1 (i.e. the longitudinal dimension direction of the filter plate 1). Therefore, the air inlet hole groups on the filter plate 1 are arranged in a layout of spaced arrangement in the width direction, and the plurality of air inlet holes 11 inside each air inlet hole group are uniformly distributed in the length direction.

[0072] Further, the plurality of dustproof plates 2 are arranged corresponding to the positions of each air inlet hole group on the first side of the filter plate 1. By precisely adjusting the opening angle of the dustproof plate 2 through the driving assembly 3, the size of the included angle between the dustproof plate 2 and the filter plate 1 can be dynamically controlled. The air flow passability of the air inlet hole group is realized: when it is necessary to enhance heat dissipation, the opening angle can be increased to increase the ventilation volume; or when it is necessary to strengthen dust prevention, the opening angle can be reduced to limit the entry of dust. This adjustable structure not only guarantees the heat dissipation requirement of the equipment inside the cabinet, but also can flexibly adjust the dustproof level according to the environmental conditions, realizing the coordination of heat dissipation performance and dustproof effect.

[0073] Specifically, the above dustproof device realizes the cooperative operation of ventilation adjustment and self-cleaning through the linkage assembly 5. When the driving assembly 3 adjusts the opening angle of the dustproof plate 2 relative to the filter plate 1, the linkage assembly 5 synchronously drives the cleaning member 41 to pass through the corresponding air inlet hole 11 for cleaning, which not only realizes precise control of the ventilation volume, but also automatically removes the dust on the filter plate 1, effectively solving the problem of reduced ventilation efficiency caused by dust accumulation in traditional dustproof devices.

[0074] Figure 4 For Figure 2 The enlarged view of A shown.

[0075] In an illustrative embodiment, as Figures 2 to 4As shown, the driving assembly 3 comprises a rotating shaft 31, a driving motor 32, a synchronous belt 33 and two mounting plates 34. The two mounting plates 34 are symmetrically arranged on the two sides of the dust filter plate 1 in the second direction; the rotating shaft 31 extends along the second direction and is rotatably arranged at the two ends of the two mounting plates 34; the driving motor 32 is arranged outside one of the mounting plates 34, and the output end of the driving motor 32 is connected with the rotating shaft 31 through the synchronous belt 33; wherein the two ends of the dustproof plate 2 close to the axis are connected with the rotating shaft 31 through the connecting part 21.

[0076] According to the above arrangement, the driving assembly 3 realizes stable and reliable driving of the dustproof plate 2 through the cooperation of the rotating shaft 31, the synchronous belt 33 and the driving motor 32. The rotating shaft 31 extends along the second direction and is supported by the two mounting plates 34, which ensures the stability of rotation; the driving motor 32 drives the rotating shaft 31 to rotate through the synchronous belt 33, which has the advantages of accurate transmission and low noise; the dustproof plate 2 is fixedly connected with the rotating shaft 31 through the connecting part 21, so that the torque of the driving motor 32 can be effectively converted into the opening and closing action of the dustproof plate 2. This structural design not only ensures the accuracy and response speed of the angle adjustment of the dustproof plate 2, but also improves the rigidity and durability of the overall structure through the symmetrically arranged mounting plates 34.

[0077] According to the embodiment of the present application, as shown in Figure 3 The main structure of the dust filter plate 1 is provided with side plates 13 on both sides in the length direction (the second direction). The two side plates 13 respectively extend outwardly from the second side (usually the outer side) of the dust filter plate 1, forming a reliable mounting base for mounting the mounting plates 34. The protruding arrangement of the side plates 13 not only increases the structural strength of the dust filter plate 1, but also ensures the installation stability of the driving assembly 3 and the linkage assembly 5.

[0078] Figure 5 The structure diagram of the linkage assembly provided by the embodiment of the present application is shown in

[0079] In an exemplary embodiment, as shown in Figure 2 and Figure 5 One end of the cleaning member 41 is connected to the second side of the dust filter plate 1 through the elastic rope 42, and the other end is connected to the linkage assembly 5 through the traction rope 43; wherein the traction rope 43 passes through the air inlet hole 11, and the linkage assembly 5 retracts and releases the traction rope 43, so that the cleaning member 41 reciprocates through the air inlet hole 11 to clean the air inlet hole 11.

[0080] According to the above setting mode, when the linkage assembly 5 tightens the traction rope 43, the cleaning piece 41 is driven to pass through the air inlet hole 11 to remove dust; then the restoring force of the elastic rope 42 makes the cleaning piece 41 automatically reset, forming a reciprocating cleaning motion, which ensures that the cleaning piece 41 can accurately pass through the air inlet hole 11 to effectively clean; the arrangement mode of the traction rope 43 passing through the air inlet hole 11 makes the cleaning action and the opening and closing of the dustproof plate 2 realize mechanical linkage, so that automatic cleaning can be completed without additional power, and the self-maintenance ability and long-term operation reliability of the dust removal device are improved.

[0081] According to the embodiment of the present application, as shown in Figure 3 The second side of the dust filter plate 1 is also provided with a plurality of auxiliary plates 12 distributed equidistantly along the width direction (the first direction). These auxiliary plates 12 are made of high-strength materials and are firmly connected with the dust filter plate 1 by welding or bolt fixing, providing a reliable fixed fulcrum for the elastic rope 42, ensuring that the cleaning piece 41 always maintains a stable motion track during reciprocating motion. The equidistant distribution of the auxiliary plates 12 avoids mutual interference during cleaning.

[0082] Figure 6 The cross-sectional view of the linkage assembly provided by the embodiment of the present application.

[0083] In an exemplary embodiment, as shown in Figures 4 to 6 The linkage assembly 5 includes a traction shaft 51, two torsional springs 54, a plurality of trigger portions 52 and a receiving portion 53. The traction shaft 51 extends in the second direction, and both ends are rotatably arranged on the two mounting plates 34, and the traction rope 43 is connected to the circumferential surface of the traction shaft 51; the two torsional springs 54 are respectively connected to the two ends of the traction shaft 51 and the two mounting plates 34 to apply a reset torque to the traction shaft 51; the plurality of trigger portions 52 are equiangularly distributed on the circumference of the rotating shaft 31, and a recess is formed between two adjacent trigger portions 52, and the plurality of trigger portions 52 rotate with the rotating shaft 31; the receiving portion 53 is arranged on the traction shaft 51 and initially faces the rotating shaft 31 and is parallel to the first direction; wherein, when the rotating shaft 31 rotates and drives the dustproof plate 2 to increase the opening angle, at least one trigger portion 52 abuts against the first side of the receiving portion 53, so that the receiving portion 53 drives the traction shaft 51 to rotate and wind the traction rope 43, and when the recess faces the receiving portion 53, the two torsional springs 54 drive the traction shaft 51 to reset and release the traction rope 43.

[0084] Specifically, when the rotation shaft 31 drives the dustproof plate 2 to increase the opening angle, the trigger part 52 pushes the receiving part 53 to rotate the traction shaft 51 to wind the traction rope 43, and drive the cleaning part 41 to clean; when the concave part between the two trigger parts 52 is aligned with the receiving part 53, the reset torque of the torsional spring 54 makes the traction shaft 51 quickly rotate to release the traction rope 43. Through the mechanical cooperation of the trigger part 52 and the receiving part 53, it is ensured that the cleaning action is completely synchronized with the opening and closing of the dustproof plate 2; the elastic reset characteristics of the torsional spring 54 are used to realize the automatic winding and unwinding of the traction rope 43; the equiangular distribution of the plurality of trigger parts 52 enables the cleaning action to be triggered multiple times during the rotation of the dustproof plate, thereby improving the cleaning frequency and effect, and the overall structure is simple and reliable, and the maintenance cost is low.

[0085] According to the embodiment of the application, the trigger part 52 and the receiving part 53 are both in a plate structure, which has the characteristics of simple structure and high strength. The design angle of the fan-shaped concave part formed between the two adjacent trigger parts 52 is preferably 20°, which not only ensures sufficient triggering frequency, but also avoids interference between adjacent trigger parts 52. This precise angle configuration enables the dustproof plate 2 to trigger the cleaning action once every 20° of rotation, thereby realizing the best matching of the cleaning frequency and the rotation angle of the dustproof plate 2. The cooperation of the plate-shaped trigger part 52 and the receiving part 53 with the design of the fan-shaped concave part not only improves the reliability of mechanical contact, but also ensures the accuracy and consistency of each triggering action, so that the cleaning assembly 4 can maintain stable working performance during the whole rotation of the dustproof plate 2.

[0086] The receiving part 53 is further configured to, when the dustproof plate 2 rotates by 20°, drive the cleaning part 41 to complete cleaning and disengage from the trigger part 52, and accurately reset to the initial position under the action of the torsional spring 54.

[0087] According to the embodiment of the application, the trigger part 52 is provided as four, and the two adjacent trigger parts 52 are uniformly distributed in the circumferential direction of the rotation shaft 31 at an interval of 20°. In the working state of the system, the dustproof plate 2 has an initial opening angle of 40° and a maximum opening angle of 120°. When the dustproof plate 2 is at the initial opening angle of 40°, the first trigger part 52 is in abutting state with the receiving part 53; as the opening angle of the dustproof plate 2 gradually increases to the maximum opening angle of 120°, due to the distribution of the interval angle (i.e. 20°), it is ensured that the four trigger parts 52 can sequentially complete four effective triggers with the receiving part 53, thereby realizing the triggering of the cleaning action of the dustproof plate 2 multiple times in the whole opening stroke. This design ensures that uniform and reliable cleaning triggering effect can be obtained regardless of the opening angle position of the dustproof plate 2.

[0088] In an exemplary embodiment, as shown in FIG. 2, the dustproof plate 2 is provided with a cleaning assembly 4, and the cleaning assembly 4 is arranged on the rotation shaft 31 of the dustproof plate 2. Figure 4As shown, the mounting plate 34 is provided with a stop portion 341; the traction shaft 51 is provided with a limiting portion 511; wherein, when the traction shaft 51 is reset, the limiting portion 511 and the stop portion 341 abut against each other to overcome the reset torque, so as to keep the receiving portion 53 at the initial position.

[0089] In detail, when the torsion spring 54 drives the traction shaft 51 to rotate and reset, the limiting portion 511 and the stop portion 341 on the mounting plate 34 abut against each other, which not only effectively absorbs the residual reset torque to avoid overshoot, but also ensures that the receiving portion 53 is accurately stopped at the initial position parallel to the first direction, so as to prepare for the next triggering of the cleaning action. This mechanical limiting not only improves the working reliability of the linkage assembly 5, but also eliminates the position error in the reset process through physical limiting, so as to ensure that the triggering position of each cleaning action is consistent, and the opening and closing angle of the dustproof plate is always accurately corresponding to the cleaning stroke.

[0090] In an illustrative embodiment, as shown in Figure 6 the second side of the receiving portion 53 opposite to the first side is configured as a slope 531; the receiving portion 53 is radially slidably arranged in the accommodation groove 512 of the traction shaft 51 and moves between an initial position extending out of the accommodation groove 512 and a retracted position at least partially retracted into the accommodation groove 512; wherein, when the rotating shaft 31 rotates and drives the dustproof plate 2 to decrease the opening and closing angle, the at least one triggering portion 52 abuts against the second side of the receiving portion 53, so as to move the receiving portion 53 from the initial position to the retracted position, and when the recess faces the receiving portion 53, the receiving portion 53 is reset by gravity.

[0091] According to the above arrangement, when the dustproof plate 2 decreases the opening and closing angle, the triggering portion 52 slides along the slope 531 and pushes the receiving portion 53 to retract into the accommodation groove 512, so as to avoid mechanism interference; when the recess is aligned with the receiving portion 53, the receiving portion 53 is automatically reset to the initial position under the action of gravity. The smoothness of the closing action of the dustproof plate 2 is ensured by mechanical avoidance; the guiding effect of the slope 531 enables the triggering portion 52 to smoothly transition; the gravity reset mechanism saves an additional elastic element and simplifies the structure.

[0092] This bidirectional triggering mechanism enables the linkage assembly 5 to not only trigger cleaning in response to the opening action of the dustproof plate 2, but also automatically avoid interference in the closing action of the dustproof plate 2, so as to realize the conflict-free collaborative operation of the dustproof and cleaning functions.

[0093] In an illustrative embodiment, as shown in Figure 6 the accommodation groove 512 is provided with a limiting groove 513 extending in the radial direction of the traction shaft 51, and the width or thickness of the limiting groove 513 is greater than that of the accommodation groove 512; wherein, the opposite sides of the receiving portion 53 are provided with limiting protrusions 532 slidably matched with the limiting groove 513.

[0094] Specifically, the widened or thickened design of the limiting groove 513 provides a stable guide rail for the limiting protrusion 532, which not only ensures that the receiving part 53 can smoothly slide in the avoiding groove 512 to complete the avoiding action, but also prevents the receiving part 53 from being pulled out or deviated by mechanical limiting.

[0095] According to an embodiment of the present application, as shown in the axial cross-sectional view of the traction shaft 51, the thickness of the limiting groove 513 is greater than that of the avoiding groove 512, and at this time, the limiting protrusion 532 is arranged at the end of the first side and the second side of the receiving part 53, and forms a sliding fit with the limiting groove 513, and can also prevent the receiving part 53 from sliding out of the avoiding groove 512. Figure 6

[0096] According to another embodiment of the present application, the width of the limiting groove 513 is greater than that of the avoiding groove 512 (i.e. the size in the second direction), and at this time, the limiting protrusion 532 is arranged on both sides of the receiving part 53 in the second direction, i.e. the two sides adjacent to the first side and the second side.

[0097] Figure 7 A perspective view of a server cabinet body according to an embodiment of the present application is provided;

[0098] In an illustrative embodiment, as shown in Figure 7 The dustproof device further comprises a temperature sensor 6 arranged in the cabinet and configured to monitor a real-time temperature value in the cabinet, and a control unit configured to control the driving motor 32 to drive the dustproof plate 2 to increase the opening angle when the real-time temperature value rises and reaches a set threshold value, wherein the opening angle increases in steps as the temperature rises. When the real-time temperature value decreases, the control unit controls the driving motor 32 to drive the dustproof plate 2 to decrease the opening angle.

[0099] In detail, the temperature sensor 6, the driving motor 32 and the control unit are electrically connected, the temperature sensor 6 sends the detected temperature signal to the control unit, when the temperature sensor 6 detects that the temperature inside the cabinet body rises and reaches a preset temperature threshold value, the control unit controls the driving motor 32 to drive the rotating shaft 31 to rotate forward, thereby increasing the opening angle of the dustproof plate 2, and when the temperature sensor 6 detects that the temperature inside the cabinet body decreases, the control unit controls the driving motor 32 to drive the rotating shaft 31 to rotate reversely, thereby decreasing the opening angle of the dustproof plate 2.

[0100] ​Further, a stepped temperature control strategy is adopted, when the internal temperature of the cabinet is 20℃, the opening and closing angle of the dustproof plate 2 is 40°; when the temperature rises to 25℃, the angle increases to 60°; when the temperature reaches 30℃, the angle is adjusted to 80°; when the temperature continues to rise to 35℃, the angle expands to 100°; and under the condition of 40℃, the dustproof plate 2 is fully opened to the maximum angle of 120°. The opening and closing angle change of 20° in a single adjustment is perfectly matched with the 20° interval distribution of the triggering part 52, ensuring that the dustproof plate 2 can trigger a cleaning action every time it rotates 20° when the temperature rises by one step. The linkage design of temperature-angle-cleaning makes the ventilation adjustment and the self-cleaning process completely synchronized, which not only realizes the accurate control of temperature, but also ensures that the dustproof plate can be cleaned and maintained in time at each working position.

[0101] In an illustrative embodiment, as shown in Figure 7 The dustproof device further comprises a buzzer 7 arranged in the cabinet and configured to trigger an alarm when the real-time temperature value exceeds a set over-temperature threshold.

[0102] According to the above setting mode, the buzzer 7 is electrically connected with the temperature sensor 6. When the temperature sensor 6 detects that the internal temperature of the cabinet exceeds the preset over-temperature threshold (40℃), at this time, the dustproof plate 2 rotates to the maximum opening and closing angle of 120° to realize maximum ventilation and heat dissipation; the buzzer 7 sends an alarm signal to timely remind the staff to handle the over-temperature condition.

[0103] In an illustrative embodiment, as shown in Figure 3 The cleaning assembly 4 further comprises a plurality of dust collecting boxes 44 extending along the second direction and arranged below the plurality of cleaning pieces 41 corresponding to the plurality of rows of air inlet hole groups.

[0104] Specifically, the cleaning assembly 4 is particularly configured with a plurality of dust collecting boxes 44 extending along the length direction (the second direction). These dust collecting boxes 44 are respectively arranged below each row of air inlet hole groups and accurately cooperate with the movement track of the cleaning pieces 41. When the cleaning pieces 41 perform reciprocating cleaning action, the dust and impurities removed from the air inlet hole 11 can directly fall into the dust collecting box 44 below. The dust is collected immediately, avoiding secondary pollution, improving the actual dust removal efficiency of the cleaning system, and simplifying the dust cleaning work during maintenance.

[0105] According to the embodiment of the present application, as shown in Figure 3As shown, when the dust collecting box 44 is provided, the cleaning piece 41 corresponding to the uppermost row of the air inlet hole group is fixed to the auxiliary plate 12 at the top end of the elastic rope 42 thereof; and the elastic ropes 42 of the cleaning pieces 41 of the other rows are directly fixed to the bottom surface of the lower dust collecting box 44. This layered fixing design not only ensures that all the cleaning pieces 41 can obtain stable fixing support, but also avoids the problem of lack of fixing point for the top cleaning piece 41 through the provision of the uppermost auxiliary plate 12.

[0106] According to the embodiment of the present application, the auxiliary plate 12 is integrally formed with the same material as the dust filtering plate 1, which ensures the connection strength.

[0107] Figure 8 The structure diagram of the cleaning piece provided by the embodiment of the present application.

[0108] In an exemplary embodiment, as shown in Figure 8 The cleaning piece 41 comprises an elastic body 411 and bristles 412. The elastic body 411 is configured as a column, and the cross-sectional diameter of the elastic body 411 is smaller than the diameter of the air inlet hole 11; and the bristles 412 are uniformly distributed on the surface of the elastic body 411 in the circumferential direction.

[0109] The cleaning piece 41 adopts the composite structure design of the elastic body 411 and the bristles 412. The columnar elastic body 411 has a diameter slightly smaller than the air inlet hole 11, which ensures that it can smoothly pass through the hole without being stuck. The bristles 412 uniformly distributed on the surface of the elastic body 411 can clean the inner wall of the air inlet hole 11 in all directions during reciprocating motion, effectively removing accumulated dust and impurities. The flexible property of the elastic body 411 enables it to adapt to slight deviations in different hole diameters, ensuring cleaning effect while avoiding damage to the hole wall. This design not only achieves efficient and thorough cleaning effect, but also ensures the reliability of long-term use through simple mechanical structure, greatly reducing the maintenance cost.

[0110] According to the embodiment of the present application, the cleaning piece 41 adopts an elastic body 411 made of sponge material, which has flexible properties that can ensure smooth passage through the air inlet hole 11 and effectively remove dust accumulated on the hole wall with the surface bristles 412.

[0111] According to an embodiment of the present invention, the working principle of the dustproof device is as follows: when the temperature inside the cabinet rises, the temperature sensor 6 triggers the drive motor 32 to drive the dustproof plate 2 to rotate upward. At this time, the rotating shaft 31 rotates counterclockwise, driving the trigger part 52 to push the receiving part 53, causing the traction shaft 51 to rotate clockwise and tighten the traction rope 43, pulling the cleaning part 41 through the air inlet 11 to complete a cleaning action; after the trigger part 52 is disengaged, the torsion spring 54 resets the traction shaft 51. This linkage mechanism ensures that the dustproof plate 2 can automatically clean the air inlet 11 every time it is opened, which not only ensures the ventilation and heat dissipation effect, but also prevents the dust filter plate 1 from being blocked. When the temperature drops, the dustproof plate 2 rotates downward, the rotating shaft 31 rotates clockwise, and the trigger part 52 pushes the receiving part 53 to retract the clearance slot 512 through the inclined surface 531, avoiding unnecessary cleaning actions and effectively extending the service life of the cleaning component 4. The entire device automatically adjusts the opening and closing angle of the dustproof plate 2 through temperature sensing: when the temperature rises, the opening and closing angle is increased to enhance ventilation, and when the temperature drops, the opening and closing angle is reduced to enhance dust prevention, achieving an intelligent balance between heat dissipation and dust prevention.

[0112] The embodiment of the present invention further provides a server cabinet, such as Figure 1 and Figure 7 As shown, it includes a cabinet 8, and the side wall of at least one side of the cabinet 8 is provided with multiple ventilation holes 81 distributed at intervals along the height direction of the cabinet 8; the above-mentioned dustproof devices, multiple dustproof devices are respectively arranged at the ventilation holes 81.

[0113] According to an embodiment of the present invention, Figure 1 As shown, a cabinet door 82 is provided on one side of the cabinet body 8, and a plurality of vents 81 evenly distributed along the height direction are provided on both sides adjacent to the cabinet door 82. Each vent 81 is equipped with the aforementioned dustproof device.

[0115] In an illustrative embodiment, Figure 3 、 Figure 7 and Figure 9 As shown, the server cabinet further includes a connection assembly 9, which includes a magnetic unit 91, a magnetized unit 92, a first clip 93, and a second clip 94. The magnetic unit 91 is disposed in the mounting slot 83 of the cabinet 8 and is located at the upper edge of the vent 81; the magnetized unit 92 is disposed at the top of the dust filter plate 1 facing the cabinet 8 and magnetically engages with the magnetic unit 91; the first clip 93 is disposed on the cabinet 8 and is located at the lower edge of the plurality of vents 81; and the second clip 94 is disposed at the bottom of the dust filter plate 1 facing the cabinet 8 and engages with the first clip 93.

The first clamping groove 933 and the second clamping groove 943 are clamped and matched.

[0117] Specifically, a dedicated mounting groove 83 is arranged at each air vent 81 of the cabinet 8, and the magnetic attraction unit 91 is embedded as an upper fixing point. The magnetic attraction unit 91 is matched with the magnetic attraction unit 92 fixedly installed at the top of the dust filter plate 1, and the two are preliminarily positioned by magnetic attraction. In particular, the outer surfaces of the magnetic attraction unit 92, the second vertical part 942 of the second buckle 94, and the outer surfaces of the side plates 13 on both sides of the dust filter plate 1 are flush, so as to ensure the all-around sealing between the dust filter plate and the cabinet, and effectively prevent dust from entering from the side gap. Further, the first buckle 93 is arranged along the lower edge of the cabinet 8 to form an upward first clamping groove 933; the second buckle 94 extending in the length direction is arranged at the bottom of the dust filter plate 1 to form a second clamping groove 943. During installation, the iron bar at the top of the dust filter plate 1 is first aligned and attracted to the magnetic attraction piece, and then the first buckle 93 and the second buckle 94 are completely engaged and locked by horizontal sliding.
