A guard assembly for an electrical switchgear cabinet

Abstract

This utility model relates to the field of protection technology for distribution cabinets, specifically a protection component for electrical distribution cabinets, including a fixed base. The distribution cabinet is fixedly connected to the top of the fixed base, and the fixed base includes a waterproof fixing seat. The beneficial effects are: by rotating the handle, the threaded rod and two movable blocks make threaded movements, causing the movable blocks to slide along the inner wall of the limiting groove, changing the width of the scissor-type rotating rod one and scissor-type rotating rod two. Simultaneously, this pushes the protection rod and the limiting frame to move, increasing the gap between them, thus achieving width adjustment of the protection mechanism and improving the adaptability of the device. At the same time, it allows the plug-in frame one to be inserted into the inner wall of the fixed frame, and the plug block to be inserted into the slot on the plug-in frame, enabling the plug-in frame of one protection mechanism to be quickly fixed to the side wall of the fixed support of another protection mechanism, achieving rapid installation and disassembly of the protection mechanism and avoiding inconvenience to maintenance personnel.

Description

Technical Field

[0001] This utility model relates to the field of protection technology for power distribution cabinets, specifically a protection component for electrical power distribution cabinets. Background Technology

[0002] Electrical distribution cabinets, as crucial equipment in power systems, are widely used in industrial, commercial, and civil buildings for distributing, controlling, and protecting electrical energy. In practical applications, to ensure the safe operation of electrical distribution cabinets and prevent accidental contact by personnel and the impact of external factors, protective mechanisms are typically installed.

[0003] In existing technologies, a common approach to protecting electrical distribution cabinets is to install fixed-size guardrails. These guardrails are typically made of metal and are fixed around the distribution cabinet using welding or bolting to form a protected area. To a certain extent, these fixed guardrails can provide isolation and protection, restricting personnel access to the distribution cabinet, reducing the risk of accidental electric shock, and also preventing some external objects from colliding with and damaging the distribution cabinet.

[0004] However, existing technologies have several problems. First, the fixed dimensions of the guardrails prevent flexible adjustments based on the specific conditions of the installation site. When the installation space for the distribution cabinet is limited, or the area to be protected has an irregular shape, or when multiple distribution cabinets have different sizes, fixed-size guardrails may not be a perfect fit, resulting in poor protection or wasted space. Second, in situations requiring maintenance, repair, or upgrades of the distribution cabinets, fixed guardrails may inconvenience operators, requiring significant time and effort for disassembly and reinstallation. Furthermore, with the continuous development of power systems and the constant changes in application scenarios, the requirements for distribution cabinet protection are constantly increasing. Existing guardrail technologies still have certain shortcomings in terms of convenience and adaptability, making it difficult to meet increasingly diverse needs. Utility Model Content

[0005] The purpose of this invention is to provide a protective component for electrical distribution cabinets to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective component for an electrical distribution cabinet, including a fixed base, the top of which is fixedly connected to the distribution cabinet, the fixed base including a waterproof fixing seat, the top of which is provided with four roller grooves, and the inner wall of the roller grooves is movably connected to a protective mechanism; The protective mechanism includes four fixed support members. The bottom side of each of the four fixed support members is fixedly connected to a waterproof fixing seat. Each fixed support member includes a fixed support rod. A limiting groove is provided on one side of the fixed support rod. Two movable blocks are slidably connected to the inner wall of the limiting groove. One end of each of the two movable blocks is rotatably connected to a scissor rod.

[0007] Preferably, a protective rod is rotatably connected to the middle of the scissor-type rotating rod, and a roller is rotatably connected to the bottom of the protective rod, with the roller inserted into the roller groove.

[0008] Preferably, the end of the scissor rod one away from the movable block is slidably connected to a limiting frame, the bottom of the limiting frame is rotatably connected to a roller, the end of the scissor rod one inside the limiting frame is rotatably connected to a scissor rod two, the end of the scissor rod two away from the scissor rod one is slidably connected to a plug-in frame, and a slot is provided on one side of the plug-in frame.

[0009] Preferably, a snap-fit ​​component is fixedly connected to the side of the fixed support rod away from the movable block. The snap-fit ​​component includes a fixed frame, which is inserted into a plug-in frame. An insert block is fixedly connected to the inner wall of the fixed frame, and the insert block is inserted into a slot opened on the plug-in frame.

[0010] Preferably, the fixed support rod is internally rotatably connected to a threaded rod, and the outer wall of the threaded rod is threadedly connected to two movable blocks.

[0011] Preferably, a bevel gear one is fixedly connected to the middle of the threaded rod, a bevel gear two is meshed on one side of the bevel gear one, a throttle handle is fixedly connected to one end of the bevel gear two, and the throttle handle is rotatably connected to the middle of the fixed support member.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model proposes a protective component for electrical distribution cabinets. The protective mechanism, in conjunction with a fixed base, involves rotating a bevel gear by holding a handle. This causes a threaded rod and two movable blocks to move in a threaded motion, allowing the movable blocks to slide along the inner wall of a limiting groove. This changes the width of the scissor-type rotating rods one and two, simultaneously pushing the protective rod and the limiting frame to roll within roller grooves, increasing the gap between them. This allows for width adjustment of the protective mechanism, improving its adaptability. It also allows the insertion frame one to be inserted into the inner wall of the fixed frame, and the insertion block to be inserted into the slot on the insertion frame. This enables the insertion frame of one protective mechanism to be quickly fixed to the side wall of the fixed support of another protective mechanism, facilitating rapid installation and disassembly of the protective mechanism and avoiding inconvenience for maintenance personnel.

[0015] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Please see the appendix Figure 1-5 This application provides the following technical solutions.

[0017] A protective assembly for an electrical distribution cabinet includes a fixed base 1, with a distribution cabinet 2 fixedly connected to the top of the fixed base 1. The fixed base 1 includes a waterproof mounting seat 11, with four roller grooves 12 on the top of the waterproof mounting seat 11. A protective mechanism 3 is movably connected to the inner wall of the roller grooves 12. The protective mechanism 3 includes four fixed support members 31, with one bottom side of each of the four fixed support members 31 fixedly connected to the waterproof mounting seat 11. Each fixed support member 31 includes a fixed support rod 311, with a limiting groove 312 on one side of the fixed support rod 311. Two movable sliding grooves are slidably connected to the inner wall of the limiting groove 312. The movable block 33 has two movable blocks 33, one end of which is rotatably connected to a scissor rod 34. The middle of the scissor rod 34 is rotatably connected to a protective rod 36. The bottom of the protective rod 36 is rotatably connected to a roller 37, which is inserted into the roller groove 12. The end of the scissor rod 34 away from the movable block 33 is slidably connected to a limit frame 35. The bottom of the limit frame 35 is rotatably connected to the roller 37. The end of the scissor rod 34 inside the limit frame 35 is rotatably connected to a scissor rod 39. The end of the scissor rod 39 away from the scissor rod 34 is slidably connected to a plug frame 38. A slot is provided on one side of the plug frame 38.

[0018] It should be noted that during use, the operator first constructs the waterproof mounting base 11 according to the terrain and the size and installation requirements of the distribution cabinet 2. Then, as needed, one side of each of the several protection mechanisms 3 is fixedly connected to the waterproof mounting base 11. Simultaneously, the rollers 37 are inserted into the roller grooves 12. After all the protection mechanisms 3 are fixed, the operator rotates the handle 316 to drive the second bevel gear 315, which in turn drives the first bevel gear 314, which in turn drives the handle 316. The handle 316 then rotates the fixed support rod 31. The internal mechanism 31 moves in a threaded motion with the movable block 33, causing the two movable blocks 33 to move towards each other. This drives the scissor rod 34, which is rotatably connected to the movable block 33, to rotate and extend. This pushes the protection rod 36 and the limiting frame 35 to move, increasing the distance between them. The limiting frame 35 and the protection rod 36 roll in the roller groove 12 through the roller 37 fixed at the bottom to reduce friction. At the same time, the scissor rod 39 extends due to the rotation of the scissor rod 34, thereby adjusting the width of the protection mechanism 3. This allows it to be fully adapted to distribution cabinets 2 of different sizes, improving the protection effect and saving space.

[0019] A snap-fit ​​member 32 is fixedly connected to the side of the fixed support rod 311 away from the movable block 33. The snap-fit ​​member 32 includes a fixed frame 321, which is inserted into a plug frame 38. A plug block 322 is fixedly connected to the inner wall of the fixed frame 321. The plug block 322 is inserted into a slot opened on the plug frame 38. A threaded rod 313 is rotatably connected inside the fixed support rod 311. The outer wall of the threaded rod 313 is threadedly connected to two movable blocks 33. A bevel gear 314 is fixedly connected to the middle of the threaded rod 313. A bevel gear 315 meshes with one side of the bevel gear 314. A handle 316 is fixedly connected to one end of the bevel gear 315. The handle 316 is rotatably connected to the middle of the fixed support member 31.

[0020] It should be noted that while the scissor-type rotating rod 34 and scissor-type rotating rod 39 extend, the scissor-type rotating rod 39 pushes the plug-in frame 38 to move and insert into the snap-fit ​​component 32. After the plug-in frame 38 is completely fitted with the inner wall of the fixed frame 321, the plug block 322 is inserted into the slot opened on one side of the plug-in frame 38. After the plug-in frames 38 of several protection mechanisms 3 are plugged and fixed with the snap-fit ​​components 32 of the corresponding protection mechanisms 3, the fixing of the protection mechanism 3 and the fixed base 1 is completed. When the distribution cabinet 2 needs to be maintained, repaired or upgraded, the operator only needs to turn the handle 316 in the opposite direction to drive the threaded rod 313 to rotate, so that the movable block 33 moves in the opposite direction on the inner wall of the limit slide groove 312, which can cause the scissor-type rotating rod 34 and scissor-type rotating rod 39 to retract, and the distance between the limit frame 35 and the protection rod 36 and the plug-in frame 38 to shrink and fold together, so as to achieve quick disassembly and avoid increasing the difficulty of maintenance personnel.

[0021] In use, the operator first constructs the waterproof mounting base 11 according to the terrain and the volume and installation requirements of the distribution cabinet 2. Then, as needed, one side of several protection mechanisms 3 is fixedly connected to the waterproof mounting base 11. Simultaneously, the rollers 37 are inserted into the roller grooves 12. After all protection mechanisms 3 are fixed, the operator rotates the handle 316 to drive the bevel gear 315 to rotate. The bevel gear 315 then drives the bevel gear 314 to rotate, which in turn drives the handle 316. The handle 316 moves threadedly within the fixed support rod 311 and the movable block 33, causing the two movable blocks 33 to move towards each other. This causes the scissor-type rotating rod 34, rotatably connected to the movable block 33, to rotate and extend, pushing the protection rod 36 and the limiting frame 35 to move, widening the distance between them. The limiting frame 35 and the protection rod 36 roll within the roller grooves 12 via the rollers 37 fixed at the bottom, reducing friction. Simultaneously, the scissor-type rotating rod 39 extends due to the rotation of the scissor-type rotating rod 34, achieving the desired effect. The width adjustment of the protection mechanism 3 allows for complete adaptation to distribution cabinets 2 of different sizes, improving protection effectiveness and saving space. As the scissor-type rotating rod 34 and 39 extend, the scissor-type rotating rod 39 pushes the plug-in frame 38 to move and insert into the snap-fit ​​component 32. After the plug-in frame 38 is fully fitted against the inner wall of the fixed frame 321, the plug block 322 is inserted into the slot on one side of the plug-in frame 38. This process is repeated when the plug-in frames 38 of several protection mechanisms 3 interact with the snap-fit ​​components 32 of their corresponding protection mechanisms 3. After the plug-in and fixing, the protection mechanism 3 and the fixed base 1 are fixed. When the distribution cabinet 2 needs maintenance, repair or upgrade, the operator only needs to turn the handle 316 in the opposite direction to drive the threaded rod 313 to rotate, so that the movable block 33 moves in the opposite direction on the inner wall of the limit slide groove 312. This will cause the scissor rod 1 34 and scissor rod 2 39 to retract, and the distance between the limit frame 35 and the protection rod 36 and the plug-in frame 38 will be reduced and they will fold together, so as to achieve quick disassembly and avoid increasing the difficulty of maintenance personnel.
