Description

Technical Field

[0001] This invention relates to the field of cabinet technology, and in particular to maintenance cabinets for monitoring and controlling outdoor electronic equipment, as well as their assembly equipment and methods. Background Technology

[0002] Server racks are typically used in network cabling rooms, floor wiring closets, central computer rooms, data centers, control centers, monitoring rooms, and monitoring centers. Examples include server racks, network racks, and control console racks. They are used to provide interfaces for various external devices, including but not limited to information equipment, control equipment, network equipment, and switching equipment, thereby enabling information collection or status control of various external devices.

[0003] However, as outdoor server racks are used for longer periods, the dust filters at the air inlets accumulate more and more dust and debris, obstructing or clogging the filter pores and hindering airflow. This negatively impacts air circulation and heat dissipation within the rack. Furthermore, in humid and rainy environments, rainwater easily enters the rack through the inlets and outlets, potentially corroding and short-circuiting the internal telecommunications equipment, thus reducing its lifespan and transmission quality. Therefore, existing maintenance server racks are prone to malfunctions due to excessive dust and moisture, preventing timely and effective transmission of front-end data to back-end services.

[0025] Compared with the prior art, the present invention provides an operation and maintenance cabinet for monitoring and controlling outdoor electronic equipment, as well as its assembly equipment and method, which has the following beneficial effects:

[0026] 1. The maintenance cabinet for monitoring and controlling outdoor electronic equipment, as well as its assembly equipment and method, prevents rainwater from flowing into the cabinet through the gaps in the heat dissipation vents during rainy days, which could easily cause short circuits in the electrical components inside the cabinet. Furthermore, when the sealing component is working, it moves the filter plate out of the cabinet, allowing rainwater to wash the filter plate, preventing dust and debris from clogging it and providing a self-cleaning effect, thus ensuring the ventilation and heat dissipation effect of the filter plate.

[0027] 2. The maintenance cabinet for monitoring and controlling outdoor electronic equipment, its assembly equipment and method, wherein when the sealing component releases the blockage of the heat dissipation hole, the pneumatic elastic telescopic tube is restored, the piston squeezes the air in the rod chamber and discharges it to the exhaust port through the air guide pipe and exhaust pipe, so that the air discharged from the exhaust port blows away some dust and impurities attached to the guide space during the blockage of the heat dissipation hole, and avoids pushing dust and impurities into the cabinet when the filter plate moves back.

[0028] 3. The maintenance cabinet for monitoring and controlling outdoor electronic equipment, its assembly equipment and method, by making the first pull rope no longer pull the lower side of the filter plate, the filter plate is no longer under force because it has been moved out of the guide space. The filter plate is only connected to the connecting rod through the slider. The filter plate can swing left and right around the round rod under the action of external rain or wind. On the one hand, it avoids the filter plate being placed vertically, which affects the rainwater washing of dust and impurities on the filter plate. On the other hand, the filter plate that can swing left and right can make the dust and impurities that are not easy to clean fall off quickly.

[0029] 4. The maintenance cabinet for monitoring and controlling outdoor electronic equipment, its assembly equipment and method, by enabling the exhaust pipe to swing left and right along the sealing plate, improves the diversity of exhaust angles of the exhaust pipe, avoids exhaust dead zones, and can blow away dust and impurities attached to the guide space from multiple angles, ensuring the cleaning effect of dust and impurities in the guide space.

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0043] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0044] Example 1: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The maintenance cabinet for monitoring and controlling outdoor electronic equipment includes a cabinet 1 and a rain sensor 101 installed on the outside of the cabinet 1, and also includes:

[0045] The heat dissipation vent group 2 is provided in two groups and is located on both sides of the cabinet 1 respectively. The two heat dissipation vent groups 2 are air inlets and air outlets respectively. Each heat dissipation vent group 2 includes several heat dissipation holes 201 opened on the cabinet 1.

[0046] The air guide plate 3 is connected to the cabinet 1 and is located on the outside of the heat dissipation vent group 2. A guiding space is formed between two adjacent air guide plates 3.

[0047] Filter plate 4 is placed inside the heat dissipation hole 201 to intercept dust and impurities entering the cabinet 1.

[0048] A sealing component is installed inside the cabinet 1 to seal the heat dissipation hole 201;

[0049] The sealed component is equipped with a pushing component for pushing the filter plate 4 to slide within the guide space.

[0050] Specifically, the cabinet 1 of the maintenance cabinet is ventilated and cooled through the heat dissipation vent group 2. The filter plate 4 intercepts dust and impurities carried in the air at the heat dissipation holes 201. When the rain sensor 101 detects rain outside the cabinet 1, the rainwater volume reaches a set threshold (e.g., ≥2mm / h) and triggers a sealing action, controlling the sealing component to block the heat dissipation holes 201. This prevents rainwater from flowing into the cabinet 1 through the gaps in the heat dissipation holes 201 during rainy days, which could easily cause short circuits in the electrical components inside the cabinet 1. When the sealing component is working, it drives the push component to move the filter plate 4 out of the cabinet 1, using rainwater to wash the filter plate 4, preventing dust and debris from clogging it. This has a self-cleaning effect and ensures the ventilation and heat dissipation effect of the cabinet 1. It should be noted that the filter plate 4 is provided with filter holes for airflow.

[0051] Example 2: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The maintenance cabinet for monitoring and controlling outdoor electronic equipment, based on embodiment 1, further includes an airtight assembly comprising an electric push rod 5 fixed to the inner wall of the cabinet 1 and an airtight part 6 fixed to the movable end of the electric push rod 5. The airtight part 6 is provided with a rubber pad 7 that moves against the inner wall of the cabinet 1. The airtight part 6 includes a movable plate 601 connected to the movable end of the electric push rod 5, a pneumatic elastic telescopic tube 602 connected to the movable plate 601, and a sealing plate 603 connected to the end of the pneumatic elastic telescopic tube 602 away from the movable plate 601. The rubber pad 7 is connected to the end of the sealing plate 603 away from the pneumatic elastic telescopic tube 602.

[0052] Specifically, when the sealing component is working, it controls the operation of the electric push rod 5. The movable end of the electric push rod 5 drives the moving plate 601 to move closer to the side wall of the cabinet 1. The moving plate 601 drives the sealing plate 603 to move synchronously through the pneumatic elastic telescopic tube 602, so that the sealing plate 603, together with the rubber pad 7, seals the heat dissipation hole 201 to prevent rainwater from entering the cabinet 1. Moreover, when the sealing component seals the heat dissipation hole 201, the rainwater that drips continuously onto the outside of the cabinet 1 exchanges heat with the cabinet 1, effectively preventing the cabinet 1 from heating up too quickly due to the sealing of the heat dissipation hole 201, thereby ensuring the normal operation of the equipment inside the cabinet 1.

[0053] Example 3: Reference Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 The maintenance cabinet for monitoring and controlling outdoor electronic equipment, based on embodiment 2, further includes a heat dissipation hole 201 and a flow guide plate 3 that are both inclined downwards. The pushing component includes a connecting rod 604 fixed to the sealing plate 603 and a slider 605 connected to the connecting rod 604. The filter plate 4 has a groove 401 for sliding the slider 605.

[0054] Specifically, when the sealing plate 603 moves toward the side wall of the cabinet 1, the sealing plate 603 pushes the filter plate 4 toward the outside of the cabinet 1 through the connecting rod 604. During this process, the connecting rod 604 drives the slider 605 to move up along the height direction of the filter plate 4, so that the filter plate 4 slides down along the guide space and moves the filter plate 4 out of the cabinet 1. Rainwater is used to wash the filter plate 4, preventing dust and debris from clogging the filter plate 4. It has a self-cleaning effect and ensures the ventilation and heat dissipation effect of the filter plate 4 in subsequent use.

[0055] Example 4: Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 9 and Figure 11 The maintenance cabinet for monitoring and controlling outdoor electronic equipment, based on embodiment 3, further includes an outer tube 6021 connected to a sealing plate 603, a piston 6022 slidably connected inside the outer tube 6021, a first elastic element 6023 disposed between the inner wall of the outer tube 6021 and the piston 6022, and an inner rod 6024 fixedly connected to the piston 6022. One end of the inner rod 6024 away from the piston 6022 passes through the outer tube 6021 and is connected to the moving plate 601.

[0056] Furthermore, the cavity containing the inner rod 6024 within the outer tube 6021 is a rod cavity, and an air inlet valve and an air outlet valve are provided in the rod cavity. The outer tube 6021 is connected to an air guide pipe 9 through the air outlet valve. The end of the air guide pipe 9 away from the outer tube 6021 passes through the sealing plate 603 and is connected to an exhaust pipe 10. Several exhaust ports 1001 are provided on the exhaust pipe 10.

[0057] Specifically, the movable plate 601 drives the sealing plate 603 to block the heat dissipation hole 201 through the pneumatic elastic telescopic tube 602. After the sealing plate 603 abuts against the inner wall of the cabinet 1, the inner rod 6024 drives the piston 6022 to move relative to the outer tube 6021, and the first elastic element 6023 is compressed. The first elastic element 6023 is set as a spring. The rod chamber of the outer tube 6021 draws air through the air inlet valve. When the sealing component releases the blockage of the heat dissipation hole 201, the pneumatic elastic telescopic tube 602 returns to its original position, and the piston 6022 squeezes the air in the rod chamber and discharges it to the exhaust port 1001 through the air guide pipe 9 and the exhaust pipe 10. The air discharged from the exhaust port 1001 blows away some dust and impurities attached to the guide space during the blocking of the heat dissipation hole 201, so as to prevent the dust and impurities from being pushed into the cabinet 1 when the filter plate 4 moves back.

[0058] Example 5: Refer to Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 and Figure 10 The maintenance cabinet for monitoring and controlling outdoor electronic equipment, based on embodiment 4, further includes a slider 605 comprising a movable block 6051 fixedly connected to a connecting rod 604 and round rods 6052 fixedly disposed on both sides of the movable block 6051. The movable block 6051 is slidably connected in a slide groove 401. The inner surface of the slide groove 401 is coated with stainless steel and a silicon-based wear-resistant coating to improve its wear resistance. A limiting groove 4011 for sliding of the round rods 6052 is provided in the slide groove 401.

[0059] Furthermore, a first support plate 8 is fixedly mounted on the outer tube 6021, a first rotating rod 801 is rotatably connected to the first support plate 8, a torsion spring connected to the first support plate 8 is sleeved on the first rotating rod 801, a first gear 802 and a first drum 803 are provided on the first rotating rod 801, a first pull rope 8031 ​​is wound and connected to the first drum 803, and the end of the first pull rope 8031 ​​away from the first drum 803 passes through the sealing plate 603 and is connected to the filter screen plate 4. A rack plate 6011 that meshes with the first gear 802 is fixedly mounted on the moving plate 601.

[0060] Specifically, the movable plate 601 drives the sealing plate 603 to block the heat dissipation hole 201 via the pneumatic elastic telescopic tube 602. After the sealing plate 603 abuts against the inner wall of the cabinet 1, the movable plate 601 squeezes the pneumatic elastic telescopic tube 602 and moves relative to the sealing plate 603. The rack plate 6011 meshes with the first gear 802 on the first rotating rod 801, and the first rotating rod 801 drives the first drum 803 to release the first pull rope 8031, so that the first pull rope 8031 ​​no longer pulls the lower side of the filter plate 4. At this time, the filter plate 4 has been moved out of the guide space and is no longer under force. The filter plate 4 is only connected to the connecting rod 604 through the slider 605. The filter plate 4 can swing left and right around the round rod 6052 under the action of external rain or wind. On the one hand, it avoids the filter plate 4 being placed vertically, which affects the rainwater washing of dust and impurities on the filter plate 4. The filter plate 4 is in an inclined state, and the concentrated action of rainwater causes large dust particles on it to fall directly. On the other hand, the filter plate 4, which can swing left and right, can make dust and impurities that are not easy to clean fall off quickly.

[0061] Example 6: Refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 9 , Figure 10 and Figure 11 The maintenance cabinet for monitoring and controlling outdoor electronic equipment, based on embodiment 5, further includes a second support plate 11 fixed on the outer tube 6021, a second rotating rod 111 rotatably connected to the second support plate 11, a second gear 112 and a second drum 113 on the second rotating rod 111, a second pull rope 1131 wound around the second drum 113, and the end of the second pull rope 1131 away from the second drum 113 passing through the sealing plate 603 and connected to the exhaust pipe 10. The sealing plate 603 has a sliding groove 12 for sliding the exhaust pipe 10, and a second elastic element 121 is provided between the inner wall of the sliding groove 12 and the exhaust pipe 10. The first gear 802 has a missing gear 8021 that intermittently meshes with the second gear 112. The sealing plate 603 has a guide wheel 13 for changing the direction of the second pull rope 1131.

[0062] Specifically, when the first rotating rod 801 rotates, the missing gear 8021 on the first rotating rod 801 rotates synchronously. The missing gear 8021 intermittently meshes with the second gear 112 on the second rotating rod 111. When the missing gear 8021 meshes with the second gear 112, the second drum 113 pulls the second pull rope 1131, causing the exhaust pipe 10 to slide in the sliding groove 12. The second elastic element 121 is stretched. The second elastic element 121 is set as a spring. When the missing gear 8021 no longer meshes with the second gear 112, the exhaust pipe 10 moves back under the pull of the second elastic element 121, so that the exhaust pipe 10 can swing left and right along the sealing plate 603, improving the diversity of the exhaust angle of the exhaust pipe 10, avoiding exhaust dead angles, and blowing away dust and impurities attached to the guide space from multiple angles, ensuring the cleaning effect of dust and impurities in the guide space; when the missing gear ratio is 1 / 3, the filter cleaning cycle is significantly improved.
