Description

Technical Field

[0001] This utility model relates to the field of electrical installation technology, specifically to an installation device for electrical automation protection and control. Background Technology

[0002] In the field of electrical automation, protection and control devices, as core components, are widely used in substations, power plants, and industrial power distribution systems to monitor, protect, and control power equipment (such as generators, transformers, and busbars) in real time, ensuring the reliability and safety of the power grid. Traditional protection and control devices are usually installed on the surface of electrical cabinet doors by bolting. The typical installation process includes: pre-setting mounting holes on the cabinet door, aligning the device housing with the holes, using multiple sets of bolts to pass through the fixing holes on the edge of the housing and screwing them into the threaded holes of the cabinet door, and finally tightening them one by one to achieve fixation.

[0003] However, this type of installation method has significant drawbacks:

[0004] 1. Low installation efficiency: Special tools (such as wrenches and screwdrivers) are required to tighten the bolts one by one. The operation is cumbersome and time-consuming, especially in confined spaces or densely wired environments, where the installation difficulty is further increased.

[0005] 2. Inconvenient maintenance: When the equipment is repaired or upgraded, the bolts must be completely removed before the device can be taken off. Repeated disassembly and assembly can easily lead to stripped bolts, worn threaded holes, or even loss of bolts or washers, increasing maintenance costs.

[0006] 3. Insufficient protection: After the bolts are fixed, dust, oil and other contaminants can easily accumulate in the gap between the device and the cabinet door. Long-term operation may cause oxidation or poor contact at the wiring ports, leading to malfunctions or short circuits.

[0007] 4. Lack of self-locking mechanism: Traditional bolts rely on manual tightening. If they are not fully tightened, the device is prone to loosening and falling off in a vibrating environment, posing a safety hazard.

[0008] To address the aforementioned problems, some improvements have been made in existing technologies, such as using snap-fit ​​installation structures or quick-release clamps to replace bolts. However, these solutions still have limitations:

[0009] 1. The buckle structure is prone to aging: Plastic buckles are prone to deformation and breakage under long-term stress or high temperature, leading to fixation failure;

[0010] 2. Poor adaptability of quick-release clamps: The size of the clamps is strongly related to the thickness of the cabinet door and the shape of the device, making it difficult to be compatible with different models of equipment and resulting in insufficient versatility;

[0011] 3. Lack of dust protection design: Most solutions do not provide sealing protection at the connection points, allowing dust to still enter through gaps and affecting the lifespan of the equipment.

[0012] In summary, existing technologies have not effectively resolved the contradictions between efficiency, maintainability, and protection during the installation of protection and control devices. Therefore, there is an urgent need for an installation device that combines quick assembly / disassembly, self-locking limit switches, and dust protection to improve the operation and maintenance efficiency and reliability of electrical automation systems. Utility Model Content

[0013] This utility model aims to provide an installation device for electrical automation protection and control. Through a plug-in structure and a rotating protective cover design, it achieves quick installation, self-locking limit, and dust protection functions, thereby solving the technical problems of current bolt-structure installation, which is cumbersome to operate and inconvenient to maintain.

[0014] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an electrical automation protection and control installation device, including an electrical cabinet, a cabinet door installed on the electrical cabinet, a protection and control device, a wiring port on the rear side of the protection and control device, an installation cylinder fixedly connected to the rear side of the protection and control device, a through-hole in the middle of the installation cylinder, the through-hole being connected to the wiring port, an installation hole on the cabinet door, the installation cylinder being inserted into the installation hole, and the protection and control device being closely attached to the outer side of the cabinet door.

[0015] Furthermore, it also includes a locking mechanism, which includes an adjustment groove. The adjustment groove is opened on both sides of the rear end of the mounting cylinder. A docking block is slidably connected in the adjustment groove, and the outer end of the docking block extends to the outside of the mounting cylinder. By setting the adjustment groove and the docking block, after the mounting cylinder is installed in the mounting hole, it can slide outward of the adjustment groove towards the docking block, so that the docking block can lock the inside of the cabinet door and limit the mounting cylinder.

[0016] Furthermore, the locking mechanism also includes an arc-shaped spring plate, which is disposed in the adjustment groove and its end is welded and fixed to the bottom end of the adjustment groove. The outer side of the spring plate abuts against the inner end of the mating block to provide elastic restoring force.

[0017] Furthermore, a handle strip is provided on the rear side of the docking block; the handle strip can provide a force point, making it easier to move the docking block.

[0018] Furthermore, the cabinet door has two fixing strips on the inside, which are symmetrically arranged on both sides of the mounting hole. A docking groove is provided in the middle of the fixing strip, and the docking block can be inserted into the docking groove. The fixing strips make the docking block more secure, and the docking groove further limits the docking block to prevent the mounting cylinder from rotating in the mounting hole.

[0019] Furthermore, the mounting cylinder is equipped with a protective mechanism, which includes a guide rail. The guide rail consists of two symmetrically arranged protruding structures, with the center of symmetry being the axis of the mounting cylinder. The guide rail is located on the rear end face of the mounting cylinder, and its length direction is a circle centered on the axis of the mounting cylinder. A protective cover is connected to the guide rail, and the protective cover has a guide groove into which the guide rail can be inserted. After installation, the protective cover is manually rotated to a 90-degree angle. The protective cover rotates through the guide groove and the guide rail, causing the side opening and the handle to be misaligned. At this time, the protective cover limits the handle, preventing it from effectively displacing. This further restricts the installation and positioning, achieving self-locking of the device. Simultaneously, the protective cover shields the connection points of the device, reducing dust entry and blockage.

[0020] Furthermore, the protective cover is a circular cover with a diameter equal to the outer diameter of the mounting cylinder. The protective cover has a cable routing port in the center and side openings on both sides. The left and right handle strips can be inserted into the side openings simultaneously. The guide groove is an arc-shaped groove with a central angle of 90°, used to lock the protective cover after it is rotated around the mounting cylinder.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. Quick installation: The plug-in and spring-return mechanism allows for tool-free installation;

[0023] 2. Self-locking protection: Rotating the protective cover restricts the movement of the handle bar to prevent accidental loosening and also blocks dust at the connection point;

[0024] 3. Easy maintenance: The protective cover can be quickly disassembled by rotating it in the opposite direction and pulling the handle strip, reducing maintenance costs. Attached Figure Description

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0033] like Figures 1-6 As shown, an electrical automation protection and control installation device includes an electrical cabinet 1, a cabinet door 2 installed on the electrical cabinet 1, a protection and control device 3, a wiring port 301 on the rear side of the protection and control device 3, an installation cylinder 4 fixedly connected to the rear side of the protection and control device 3, an internal groove 405 through the middle of the installation cylinder 4, the internal groove 405 docking with the wiring port 301, an installation hole 202 on the cabinet door 2, the installation cylinder 4 being inserted into the installation hole 202, and the protection and control device 3 being tightly attached to the outer side of the cabinet door 2.

[0034] The mounting cylinder 4 also includes a locking mechanism, which includes an adjustment groove 403. The adjustment groove 403 is located on both sides of the rear end of the mounting cylinder 4. A mating block 401 is slidably connected within the adjustment groove 403. The outer end of the mating block 401 extends to the outside of the mounting cylinder 4. A handle strip 402 is provided on the rear side of the mating block 401 to facilitate the movement of the mating block 401. An arc-shaped spring plate 404 is provided within the adjustment groove 403. Its end is welded and fixed to the bottom end of the adjustment groove 403. The outer side of the arc-shaped spring plate 404 abuts against the inner end of the mating block 401 to provide elastic restoring force. Two fixing strips are provided on the inner side of the cabinet door 2. The fixing strips are symmetrically arranged on both sides of the mounting hole 202, and a mating groove 203 is provided in the middle of the fixing strips. Insert the mounting cylinder 4 of the protection and control device 3 into the mounting hole 202 of the cabinet door 2. During the insertion process, the inclined surfaces of the two mating blocks 401 are squeezed inward and contracted. The mating blocks 401 slide and contract into the adjustment groove 403. The compression causes the spring plate 404 in the adjustment groove 403 to contract. After the insertion is completed, the mating blocks 401 are reset by the rebound of the spring plate 404. The outer end of the mating blocks 401 is inserted into the mating groove 203 to achieve positioning. At this time, the installation is completed. Then, turn and open the cabinet door 2, and connect the wires inside the electrical cabinet 1 to the power supply line to the wiring port 301 to complete the assembly.

[0035] The mounting cylinder 4 is equipped with a protective mechanism, which includes a guide rail 406. The guide rail 406 consists of two symmetrically arranged protruding structures, with the axis of the mounting cylinder 4 as its center of symmetry. The guide rail 406 is located on the rear end face of the mounting cylinder 4, and its length direction is a circle centered on the axis of the mounting cylinder 4. A protective cover 5 is connected to the guide rail 406. The protective cover 5 has a guide groove 501, and the guide rail can be inserted into the guide groove 501. The protective cover 5 rotates with the guide rail 406 through the guide groove 501, causing the side opening 502 to be misaligned with the handle bar 402. At this time, the protective cover 5 limits the handle bar 402, preventing it from moving effectively. This further restricts the installation and positioning, achieving self-locking of the device. At the same time, the protective cover 5 shields the connection points of the device, reducing dust entry and blockage. The protective cover 5 is a circular cover with a diameter equal to the outer diameter of the mounting cylinder 4. The protective cover 5 has a cable routing port 503 in the center and side openings 502 on both sides. The left and right handle strips 402 can be inserted into the side openings 502 at the same time. The guide groove 501 is an arc-shaped groove with a central angle of 90°, which allows the protective cover 5 to be rotated 90° around the mounting cylinder 4 and then locked.

[0036] Working Principle: This embodiment provides an installation device for electrical automation protection and control. During installation, the installation cylinder 4 of the protection and control device 3 is inserted into the installation hole 202 of the cabinet door 2. During the insertion process, the inclined surfaces of the two mating blocks 401 are squeezed inward and contracted. The mating blocks 401 slide and contract into the adjusting groove 403. The compression causes the spring plate 404 in the adjusting groove 403 to contract. After the insertion is completed, the spring plate 404 rebounds and resets the mating blocks 401. The outer end of the mating blocks 401 is inserted into the mating groove 203 to achieve positioning. The installation is now complete. Then, turn and open the cabinet door 2. Pass the wires inside the electrical cabinet 1 through the built-in groove 405 and connect them to the power cord terminal 301 to complete the assembly. After installation, manually rotate the protective cover 5 to make it rotate 90 degrees. The protective cover 5 rotates through the guide groove 501 and the guide rail 406, causing the side opening 502 and the handle bar 402 to be misaligned. At this time, the protective cover 5 limits the handle bar 402, preventing it from moving effectively, thus achieving further limiting after installation and positioning.
