Description

Technical Field

[0001] This utility model belongs to the technical field of outdoor power cabinets, and in particular relates to an outdoor power cabinet. Background Technology

[0002] Outdoor power cabinets are medium- and low-voltage power distribution equipment specifically designed for outdoor environments. They are used for power distribution, control, protection, and energy metering, and are suitable for outdoor scenarios such as substations, industrial and mining enterprises, commercial buildings, and public facilities (e.g., open-air substations, factory areas, and power distribution on the exterior facades of shopping malls). Outdoor power cabinets integrate energy conversion, energy storage, power distribution, protection, and intelligent monitoring functions. Internally, they often contain rectifiers / inverters, circuit breakers / fuses, surge protectors, terminal blocks, battery packs, main controllers, and various sensors. Outdoor power cabinets are available in small / compact (depth 650mm~750mm) and medium / large / high-density integrated (depth 900mm~1200mm) sizes.

[0003] Currently, in existing power cabinets, the mounting plates and partitions are fixed inside the cabinet, making them difficult to stretch or move. When electronic components inside the power cabinet are damaged, maintenance personnel are required to repair them. This requires accessing the cabinet to a depth of 650mm to 1200mm. Due to the high-density layout of various components inside the power cabinet, the space is cramped, which restricts the movement of maintenance personnel. Furthermore, tools such as standard wrenches and multimeter probes cannot be fully utilized due to the limited space, hindering the repair of internal electronic components. Therefore, this utility model proposes an outdoor power cabinet. Utility Model Content

[0004] This utility model provides an outdoor power cabinet. Through a push-pull locking mechanism, during maintenance, the U-shaped mounting plate and mounting partition, along with their components, can be pulled out of the power cabinet body. This expands the operating space from a confined "cabinet interior" to an "open exterior," allowing maintenance personnel to operate without entering the cabinet, avoiding restrictions on limb movement. Standard wrenches, multimeters, and other tools can be freely used, significantly improving maintenance convenience. After maintenance, the U-shaped mounting plate and mounting partition are pushed back into the power cabinet body, and a first pressing screw, in conjunction with a limiting block, engages with the... The locking groove is engaged to secure the device; the vertically rotating second extrusion screw, operated by the flipping support mechanism, drives the lowering round frame and sealing plug to provide downward support on flat, hard surfaces (such as cement, asphalt, and stone slabs), or on soft surfaces (such as mud, lawn, and sand) using a conical block. This provides stable support for the pulled-out U-shaped mounting plate and mounting partition, as well as the components on both, preventing operational inconvenience or structural damage caused by sagging due to their own weight, and ensuring safety and stability during maintenance. In summary, this solves the problems in the background technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses an outdoor power supply cabinet, comprising:

[0007] The power cabinet body has a sealed cabinet door hinged to its outer wall, a U-shaped mounting plate slidably connected inside the power cabinet body, and a pair of mounting partitions fixedly connected to the inner wall of the U-shaped mounting plate. Multiple heat dissipation vents are cut on both sides of the power cabinet body.

[0008] The push-pull locking mechanism and the flip support mechanism are both located inside the power cabinet body. The push-pull locking mechanism is used to push or pull the U-shaped mounting plate to retract inward or extend outward, and the flip support mechanism is used to support and fix the U-shaped mounting plate after it extends outward.

[0009] The push-pull locking mechanism includes two pairs of slide rails, which are fixedly connected to the inner top and bottom of the power cabinet body, respectively. Sliding blocks are fixedly connected to the top and bottom of the U-shaped mounting plate, and these blocks are located within the slide rails and slidably connected to them. A pair of fixing plates are fixedly connected to one side of each of the mounting partitions, and each fixing plate has a first threaded hole. A first pressing screw is threaded into each of the first threaded holes, and one end of the first pressing screw is rotatably connected to a connecting plate via a bearing. A limiting block is fixedly connected to the side of the connecting plate away from the first pressing screw. Limiting grooves are carved into the inner walls of both sides of the power cabinet body, and the limiting blocks are engaged with and locked within these grooves.

[0010] Furthermore, the flipping support mechanism includes a pair of second extrusion screws. One side of the U-shaped mounting plate is rotatably connected to a U-shaped block via a bearing and a rotating shaft. The inner bottom end of the U-shaped block is drilled with a second threaded hole. The second extrusion screw is located inside the U-shaped block and is threadedly connected to the second threaded hole. One end of the second extrusion screw passes through the second threaded hole and is rotatably connected to a pressing circular frame via a bearing. The bottom end of the pressing circular frame is open, and a sealing plug is fitted onto the bottom opening of the pressing circular frame. The outer wall of the sealing plug is in close contact with the inner wall of the pressing circular frame.

[0011] Furthermore, the inner wall of the pressing circular frame is fixedly connected with multiple conical blocks, and the sealing plug is drilled with multiple through holes, with the conical ends of the multiple conical blocks located in the multiple through holes respectively.

[0012] Furthermore, the bottom end of the conical block is flush with the bottom end of the sealing plug, and the height of the conical block is higher than the height of the pressing circular frame.

[0013] Furthermore, each of the pair of herringbone blocks has a push-pull block on one side, and a pair of insert rods are fixedly connected to one side of the push-pull block. Each of the pair of herringbone blocks has a pair of insertion holes on one side. Each of the U-shaped mounting plates has two sets of slots on one side, and each set of slots has four slots. The inner walls of the two sets of slots are fixedly connected to fitting blocks. Each of the pairs of insert rods has a fitting groove at one end near the herringbone block. The end of the insert rod near the herringbone block passes through the insertion hole and extends into the slot. The outer wall of the insert rod is in close contact with the inner wall of the slot, and the fitting groove engages with the fitting block.

[0014] Furthermore, the inner walls of the plurality of heat dissipation vents are respectively fixedly connected with dustproof filters and waterproof breathable plates, and the waterproof breathable plates are located inside the dustproof filters.

[0015] Furthermore, a shield is fixedly connected to the top of the power cabinet body, and the top of the shield is V-shaped.

[0016] The present invention has the following advantages over the prior art:

[0017] 1. Extended and retracted for open-space maintenance: This technical solution, through its push-pull locking mechanism, allows the U-shaped mounting plate and mounting partition, along with the components on them, to be pulled out of the power cabinet body during maintenance. This expands the operating space from a "small space inside the cabinet" to an "open space outside the cabinet," allowing maintenance personnel to operate without entering the cabinet, avoiding the problem of restricted limb movement. Standard wrenches, multimeters, and other tools can be used freely, greatly improving the convenience of maintenance. After maintenance, the U-shaped mounting plate and mounting partition are pushed back into the power cabinet body and locked in place by the engagement of the first compression screw with the limit block and the limit groove.

[0018] 2. Tilting Support to Prevent Sagging Due to Self-Weight: This technical solution uses a tilting support mechanism to operate the vertically tilting second extrusion screw to drive the downward pressing round frame and sealing plug to provide downward support on flat, hard surfaces (such as cement, asphalt, and stone slabs), or to provide downward support on soft surfaces (such as mud, lawn, and sand) using a conical block. This provides stable support for the pulled-out U-shaped mounting plate and mounting partition, as well as the components on both, preventing operational inconvenience or structural damage caused by sagging due to self-weight, and ensuring safety and stability during maintenance.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0033] Please see Figures 1-7 As shown, an outdoor power supply cabinet of this utility model includes:

[0034] The power cabinet body 1 has a sealed cabinet door 2 hinged to its outer wall, and a U-shaped mounting plate 3 is slidably connected inside the power cabinet body 1. A pair of mounting partitions 4 are fixedly connected to the inner wall of the U-shaped mounting plate 3. Multiple heat dissipation vents 8 are drilled on both sides of the power cabinet body 1.

[0035] The push-pull locking mechanism 5 and the flip support mechanism 7 are both located inside the power cabinet body 1. The push-pull locking mechanism 5 is used to push or pull the U-shaped mounting plate 3 to retract inward or extend outward, and the flip support mechanism 7 is used to support and fix the U-shaped mounting plate 3 after it extends outward.

[0036] The push-pull locking mechanism 5 includes two pairs of slide rails 501, which are fixedly connected to the inner top and bottom of the power cabinet body 1, respectively. The top and bottom of the U-shaped mounting plate 3 are fixedly connected to sliding blocks 502, which are located inside the slide rails 501 and are slidably connected to them. One side of each pair of mounting partitions 4 is fixedly connected to a pair of fixing plates 503, and each pair of fixing plates 503 has a first threaded hole. A first pressing screw 504 is threaded into each pair of first threaded holes, and one end of the first pressing screw 504 is rotatably connected to a connecting plate 505 through a bearing. A limiting block 506 is fixedly connected to the side of the connecting plate 505 away from the first pressing screw 504. Limiting grooves 507 are carved into the inner walls of both sides of the power cabinet body 1, and the limiting block 506 is in the limiting groove 507 and engages with it.

[0037] In the specific implementation process, during maintenance, the maintenance personnel open the sealed cabinet door 2 and rotate the two pairs of opposing rotating first extrusion screws 504 in sequence, causing the connecting plate 505 and the limiting block 506 to move outward, so that the limiting block 506 separates from the limiting groove 507. After complete separation, the U-shaped mounting plate 3 is pulled to move outward along the slide rail 501 with the sliding block 502 (in this embodiment, the slide rail 501 adopts a heavy-duty ball slide rail (model HGR20 optional), and its length is flush with the depth of the power cabinet body 1 (e.g., when the depth of the power cabinet body 1 is 1000mm, the length of the slide rail is 1000mm); the fit clearance between the sliding block 502 and the slide rail 501 is 0.15mm-0.25mm, and the surface of the sliding block 502... Hard chrome plating (0.02mm thick) is applied to reduce wear. The U-shaped mounting plate 3 and mounting partition 4, along with the components on them, are moved out of the power cabinet body 1. The operating space is expanded from a "small space inside the cabinet" to an "open space outside the cabinet." Then, maintenance personnel can carry out maintenance work outside the cabinet without having to go deep into the cabinet, avoiding the problem of restricted limb movement. Standard wrenches, multimeters, and other tools can be used freely, greatly improving the convenience of maintenance. After maintenance, the U-shaped mounting plate 3 and mounting partition 4 are pushed back into the power cabinet body 1, and the two pairs of first extrusion screws 504 are rotated in sequence to drive the connecting plate 505 and the limiting block 506 to move towards the limiting groove 507, so that the limiting block 506 engages with the limiting groove 507, thereby locking and fixing it.

[0038] The inner walls of the multiple heat dissipation vents 8 are respectively fixedly connected with dustproof filters 9 and waterproof breathable plates 10, and the waterproof breathable plates 10 are located inside the dustproof filters 9.

[0039] By providing a dust filter 9 and a waterproof and breathable plate 10 on the heat dissipation vent 8 respectively (in this embodiment, the dust filter 9 is a 150-mesh nylon filter (pore size 0.1mm), with a filtration efficiency ≥90% and a ventilation resistance ≤5Pa; the waterproof and breathable plate 10 is a PTFE waterproof and breathable membrane (thickness 0.2mm), with a waterproof rating of IP65, an air permeability ≥500g / (m²・24h), and a weather resistance temperature range of -40℃ to 80℃), it is possible to ensure ventilation and heat dissipation while blocking dust and rainwater from entering.

[0040] The top of the power cabinet body 1 is fixedly connected to a shielding plate 11, and the top of the shielding plate 11 is V-shaped.

[0041] The shield 11 can block rainwater, and the V-shaped top of the shield 11 can guide the rainwater to flow away, preventing water from accumulating and seeping into the top of the power cabinet body 1 (the V-shaped top angle of the shield 11 is 50°±5°, the shield extends horizontally 60mm-80mm from each side of the power cabinet body, the shield 11 is made of 304 stainless steel (1.5mm thick), and the surface is sprayed with outdoor weather-resistant coating (such as fluorocarbon paint) to ensure that rainwater is quickly diverted and does not stagnate). Specific Implementation Example 2:

[0043] Please see Figures 1-2 and Figures 5-7 As shown, in a preferred embodiment, the flipping support mechanism 7 includes a pair of second extrusion screws 701. A U-shaped mounting plate 3 is rotatably connected to a U-shaped block 6 via a bearing and a rotating shaft. A second threaded hole is drilled at the inner bottom end of the U-shaped block 6. The second extrusion screws 701 are located inside the U-shaped block 6 and are threadedly connected to the second threaded hole. One end of the second extrusion screw 701 passes through the second threaded hole and is rotatably connected to a pressing circular frame 702 via a bearing. The bottom end of the pressing circular frame 702 is open, and a sealing plug 703 is fitted onto the bottom opening of the pressing circular frame 702. The outer wall of the sealing plug 703 is in close contact with the inner wall of the pressing circular frame 702.

[0044] In the specific implementation process, after the U-shaped mounting plate 3 and the mounting partition 4, as well as the components on them, are removed from the power cabinet body 1, a pair of U-shaped blocks 6 are rotated downwards by 90° in sequence, so that the second extrusion screw 701, the pressing round frame 702, and the sealing plug 703 face downwards. Next, the second extrusion screw 701 is rotated to move downwards, pressing the pressing round frame 702 and the sealing plug 703 downwards until they come into contact with a flat, hard ground (such as a cement ground, asphalt ground, or stone slab ground) to provide downward support. This provides stable support for the pulled-out U-shaped mounting plate 3 and the mounting partition 4, as well as the components on them, avoiding operational inconvenience or structural damage caused by sagging due to their own weight, and ensuring safety and stability during maintenance.

[0045] The inner wall of the pressing circular frame 702 is fixedly connected with multiple conical blocks 704, and the sealing plug 703 is drilled with multiple through holes 705, and the conical ends of the multiple conical blocks 704 are respectively located in the multiple through holes 705.

[0046] When facing soft ground (such as mud, grass, sand), the sealing plug 703 is pulled to separate from the pressing circular frame 702, so that multiple conical blocks 704 are exposed, so that they can be pressed down to support the soft ground and ensure its stability.

[0047] The bottom end of the conical block 704 is flush with the bottom end of the sealing plug 703, and the height of the conical block 704 is higher than the height of the pressing circular frame 702.

[0048] The height of the cone block 704 is higher than the height of the pressing circular frame 702 (in this embodiment, the height of the cone block 704 is 8mm-12mm higher than the pressing circular frame 702, the apex angle of the cone block is 45°-60°, and the material is No. 45 steel (hardness HRC40-45 after quenching) to ensure that it is not easy to break when embedded in soft ground and the embedding resistance is moderate). When the cone block 704 is pressed down for support, it can use the protruding conical end to penetrate into the soft ground for stable support.

[0049] Each pair of herringbone blocks 6 has a push-pull block 706 on one side, and a pair of insert rods 707 are fixedly connected to one side of the push-pull block 706. Each pair of herringbone blocks 6 has a pair of insertion holes on one side. The U-shaped mounting plate 3 has two sets of slots 709 on one side, and each set of slots 709 has four slots. The inner walls of the two sets of slots 709 are fixedly connected to fitting blocks 7010. Each pair of insert rods 707 has a fitting groove 708 at one end near the herringbone block 6. The end of the insert rod 707 near the herringbone block 6 passes through the insertion hole and extends into the slot 709. The outer wall of the insert rod 707 is in close contact with the inner wall of the slot 709, and the fitting groove 708 engages with the fitting block 7010.

[0050] When the ring block 6 flips, it pulls the push-pull block 706 and a pair of insert rods 707 outwards, causing the pair of insert rods 707 to separate from the pair of slots 709 in the vertical direction. At the same time, the engaging slot 708 separates from the engaging block 7010. After complete separation, the ring block 6 is turned downwards by 90° with the assistance of the rotating shaft and bearing. After the flip is completed, the push-pull block 706 is pushed to drive the pair of insert rods 707 into the pair of slots 709 in the horizontal direction, and the engaging slot 708 engages with the engaging block 7010. The insert rods 707 and slots 709 achieve mechanical locking through interference fit (the gap is usually controlled at 0.2-0.3mm). The engaging slot 708 and engaging block 7010 form a tenon-and-mortise engagement, which makes the ring block 6 stable after flipping 90°.

[0051] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0052] All standard parts used in the application documents can be purchased from the market. All components in this application document can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The electrical components mentioned in this document are all electrically connected to the external main controller and power supply, and the main controller is a conventional known device that can play a control role.

[0053] The working principle of this utility model is as follows:

[0054] In normal operation, the U-shaped mounting plate 3 and the mounting partition 4 are located inside the power cabinet body 1. The rotating first pressing screw 504 pushes the limiting block 506 into the limiting groove 507 via the connecting plate 505 for fixation. During maintenance, the maintenance personnel open the sealed cabinet door 2 and rotate the two pairs of opposing first pressing screws 504 sequentially, causing the connecting plate 505 and the limiting block 506 to move outwards, separating the limiting block 506 from the limiting groove 507. After complete separation, the U-shaped mounting plate 3 is pulled along with the sliding length... Block 502 moves outward along slide rail 501, and the U-shaped mounting plate 3 and mounting partition 4, along with the components on them, move out of the power cabinet body 1, expanding the operating space from a "small space inside the cabinet" to an "open space outside the cabinet." Then, the push-pull block 706 and a pair of insertion rods 707 are pulled outward, causing the pair of insertion rods 707 to separate from the pair of slots 709 in the vertical direction. Simultaneously, the engaging slot 708 separates from the engaging block 7010. After complete separation, the rotary block 6 is rotated downward 90° with the assistance of the rotating shaft and bearing, driving the second extruder... With the pressure screw 701, the lower pressure frame 702, and the sealing plug 703 facing downwards, after the flipping is complete, the push-pull block 706 drives a pair of insert rods 707 to insert into a pair of horizontal slots 709, and drives the fitting groove 708 to engage with the fitting block 7010, so that the insert rods 707 and the slots 709 achieve mechanical locking through interference fit. The fitting groove 708 and the fitting block 7010 form a tenon-and-mortise engagement, causing the U-shaped block 6 to remain stable after flipping 90°. Immediately afterwards, the second extrusion screw 701 is rotated to move downwards, extruding... The pressing round frame 702 and the sealing plug 703 move downwards until they contact the flat, hard ground for downward support. When facing a soft ground, the sealing plug 703 is pulled apart from the pressing round frame 702, making multiple conical blocks 704 visible. Under the pressure of the second extrusion screw 701, the conical ends of the multiple conical blocks 704 are driven to penetrate the soft ground for support, providing stable support for the pulled-out U-shaped mounting plate 3 and mounting partition 4, as well as the components on both. Then, maintenance personnel can carry out maintenance work outside the cabinet.
