Description

Technical Field

[0001] This utility model relates to the field of shielding protection technology, specifically to a high-performance damage-resistant shielding cover. Background Technology

[0002] In the field of modern power engineering and electronic equipment applications, the stable operation and electromagnetic compatibility of high-voltage equipment are receiving increasing attention. Large transformers, reactors and other equipment generate strong electromagnetic fields during operation and are also highly susceptible to external electromagnetic interference.

[0003] Traditional shielding methods often require different shielding covers for different equipment when facing complex and variable high-voltage working environments, resulting in poor versatility. They are also cumbersome to install and disassemble, failing to meet the requirements for quick assembly and disassembly, thus affecting working time, efficiency, and downtime of high-voltage equipment. In addition, most traditional shielding covers do not have heat dissipation vents. If the heat generated by high-voltage equipment during operation cannot be dissipated in time, the internal temperature of the equipment will rise, accelerating equipment aging and affecting the continuous and stable operation of the equipment. Furthermore, in some harsh industrial environments, shielding covers must also resist external physical impacts and chemical corrosion. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a high-performance damage-resistant shielding cover, comprising: a connecting structure, wherein the outer wall of the connecting structure is slidably connected to the inner wall of the protective structure; the connecting structure includes a connecting seat, the inner wall of the connecting seat is symmetrically threaded with a threaded rod, the outer wall of the threaded rod is rotatably connected with a clamping block, the outer wall of the clamping block is fixedly connected with an anti-slip pad, the outer wall of the threaded rod away from the clamping block is fixedly connected with a knob, the outer wall of the connecting seat is fixedly connected with a grounding wire, the outer wall of the side of the connecting seat is symmetrically fixedly connected with a sliding rod, the outer wall of the sliding rod away from the connecting seat is fixedly connected with a limiting plate, the outer wall of the limiting plate is fixedly connected with a compression spring, the outer wall of the sliding rod is slidably connected with a clamping plate, and the outer wall of the clamping plate is fixedly connected with a pull ring.

[0005] Preferably, the outer wall of the clamping block is slidably connected to the inner wall of the connecting seat. By rotating the knob, the threaded rod is driven to rotate. Since the threaded rod is threadedly connected to the connecting seat and its outer wall is rotatably connected to the clamping block, the symmetrically arranged clamping blocks will slide against each other on the inner wall of the connecting seat as the symmetrically arranged threaded rod rotates.

[0006] Preferably, the outer wall of the compression spring on the side away from the limiting plate is fixedly connected to the outer wall of the clamping plate. The compression spring is located outside the slide rod. Pulling the pull ring causes the clamping plate to slide outward along the slide rod. Because the clamping plate moves closer to the limiting plate, the compression spring will be further compressed.

[0007] Preferably, the protective structure includes a cover, the outer wall of the side of the cover is symmetrically provided with heat dissipation grooves, the outer wall of the bottom of the cover is fixedly connected with a connecting plate, the outer wall of the side of the connecting plate is symmetrically provided with clamping grooves, and the outer wall of the cover is fixedly connected with a protective sleeve.

[0008] Preferably, the interior of the heat dissipation groove is connected to the interior of the cover, allowing the interior to communicate with the outside air. Heat can be carried out of the shielding cover through natural air convection. The interior of the connecting plate is connected to the interior of the cover, and the function of the connecting plate is to cooperate with the connecting structure for connection.

[0009] Preferably, the outer wall of the clamping plate is slidably connected to the inner wall of the clamping groove, the clamping block is located below the cover, the outer wall of the top of the connecting seat is in contact with the outer wall of the bottom of the connecting plate, the pull ring is pulled to make the clamping plate slide outward along the slide rod, and after the top of the connecting seat contacts the bottom of the connecting plate of the protective structure, the pull ring is released, and under the elastic force of the compression spring, the clamping plate is pushed along the slide rod into the clamping groove on the side of the connecting plate, so as to achieve a tight connection between the connecting structure and the protective structure.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model, through its connecting structure, allows for easy symmetrical sliding of the clamping blocks by rotating a knob to drive the threaded rod. This ensures that the anti-slip pads on the outer wall of the clamping blocks are tightly fitted to the connected object. Whether it is a mounting bracket for high-voltage equipment or a reactor, this ensures that the shielding cover is securely installed. Simultaneously, the pull ring, in conjunction with a compression spring, drives the clamping plate to engage with the clamping groove, allowing the connecting structure and the protective structure to connect. This ensures a tight connection while enabling quick installation and disassembly, facilitating subsequent maintenance, repair, or replacement. The grounding wire on the connecting base quickly conducts the induced charge on the shielding cover to the ground, effectively preventing static electricity accumulation.

[0012] 2. By setting up a protective structure, the heat dissipation grooves on the side of the shield cleverly utilize the principle of natural air convection to create a good heat dissipation channel for the equipment inside the shield, effectively avoiding overheating of the equipment due to heat accumulation. The protective sleeve on the outer wall of the shield provides an additional physical protective barrier for the shield, effectively resisting damage such as external collisions, scratches and possible chemical corrosion.

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] Example:

[0021] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a high-performance damage-proof shielding cover, comprising: a connecting structure 1, the outer wall of the connecting structure 1 being slidably connected to the inner wall of the protective structure 2; the connecting structure 1 includes a connecting seat 11, the inner wall of the connecting seat 11 being symmetrically threaded with a threaded rod 12, the outer wall of the threaded rod 12 being rotatably connected with a clamping block 13, the outer wall of the clamping block 13 being fixedly connected with an anti-slip pad 14, the outer wall of the threaded rod 12 away from the clamping block 13 being fixedly connected with a knob 15, the outer wall of the connecting seat 11 being fixedly connected with a grounding wire 16, the outer wall of the side of the connecting seat 11 being symmetrically fixedly connected with a sliding rod 17, the outer wall of the sliding rod 17 away from the connecting seat 11 being fixedly connected with a limiting plate 18, the outer wall of the limiting plate 18 being fixedly connected with a compression spring 19, the outer wall of the sliding rod 17 being slidably connected with a clamping plate 191, and the outer wall of the clamping plate 191 being fixedly connected with a pull ring 192.

[0022] The outer wall of the clamping block 13 is slidably connected to the inner wall of the connecting seat 11. By rotating the knob 15, the threaded rod 12 is driven to rotate. Since the threaded rod 12 is threadedly connected to the connecting seat 11 and its outer wall is rotatably connected to the clamping block 13, the symmetrically arranged clamping blocks 13 will slide against each other on the inner wall of the connecting seat 11 as the symmetrically arranged threaded rod 12 rotates.

[0023] The outer wall of the compression spring 19 on the side away from the limiting plate 18 is fixedly connected to the outer wall of the clamping plate 191. The compression spring 19 is located outside the slide rod 17. Pulling the pull ring 192 causes the clamping plate 191 to slide outward along the slide rod 17. Because the clamping plate 191 moves closer to the limiting plate 18, the compression spring 19 will be further compressed.

[0024] The protective structure 2 includes a cover 21. The outer wall of the side of the cover 21 is symmetrically provided with heat dissipation grooves 22. The outer wall of the bottom of the cover 21 is fixedly connected with a connecting plate 23. The outer wall of the side of the connecting plate 23 is symmetrically provided with clamping grooves 24. The outer wall of the cover 21 is fixedly connected with a protective sleeve 25.

[0025] The interior of the heat dissipation slot 22 is connected to the interior of the cover 21. The heat dissipation slot 22 allows the interior to communicate with the outside air, and the heat can be carried out of the shielding cover by the natural convection of the air. The interior of the connecting plate 23 is connected to the interior of the cover 21. The function of the connecting plate 23 is to cooperate with the connecting structure 1 for connection.

[0026] The outer wall of the clamping plate 191 is slidably connected to the inner wall of the clamping groove 24. The clamping block 13 is located below the cover 21. The outer wall of the top of the connecting seat 11 contacts the outer wall of the bottom of the connecting plate 23. Pulling the pull ring 192 causes the clamping plate 191 to slide outward along the slide rod 17. After the top of the connecting seat 11 contacts the bottom of the connecting plate 23 of the protective structure 2, the pull ring 192 is released. Under the elastic force of the compression spring 19, the clamping plate 191 is pushed to slide along the slide rod 17 into the clamping groove 24 on the side of the connecting plate 23, thus achieving a tight connection between the connecting structure 1 and the protective structure 2.

[0027] Working principle: When the shielding cover needs to be installed and connected, first fix the connecting seat 11 in the connection structure 1. By rotating the knob 15, the threaded rod 12 is driven to rotate. Since the threaded rod 12 is threadedly connected to the connecting seat 11 and its outer wall is rotatably connected to the clamping block 13, as the symmetrically arranged threaded rod 12 rotates, the symmetrically arranged clamping blocks 13 will slide close to each other on the inner wall of the connecting seat 11. The anti-slip pad 14 on the outer wall of the clamping block 13 can increase the friction between it and the object being connected, thereby firmly connecting the shielding cover to a specific position, such as connecting it to the mounting bracket of high voltage equipment or reactors and other components that need to be shielded.

[0028] Next, the protective structure 2 is connected and assembled with the connecting structure 1. Pull the pull ring 192 to make the clamping plate 191 slide outward along the slide rod 17. As the clamping plate 191 moves closer to the limiting plate 18, the compression spring 19 is further compressed. When the top of the connecting seat 11 contacts the bottom of the connecting plate 23 of the protective structure 2, release the pull ring 192. Under the elastic force of the compression spring 19, the clamping plate 191 is pushed to slide along the slide rod 17 into the clamping groove 24 on the side of the connecting plate 23, realizing a tight connection between the connecting structure 1 and the protective structure 2, ensuring the integrity and stability of the entire shielding structure. At the same time, the grounding wire 16 on the connecting seat 11 can conduct the induced charge on the shielding cover to the ground in time, ensuring the shielding effect and preventing static electricity accumulation from damaging the equipment.

[0029] The enclosure 21, as the main shielding component, is made of highly conductive metals such as copper or aluminum. The conductivity of the metal is used to shield electric and magnetic fields, preventing the internal equipment from being affected by external electromagnetic interference. It also prevents the electromagnetic radiation generated by the internal equipment from leaking outward. The heat dissipation grooves 22 on the side of the enclosure 21 are used for heat dissipation of the internal equipment. Since the internal equipment may generate heat when the enclosure is working, the heat dissipation grooves 22 allow the internal and external air to communicate. The heat can be carried out of the enclosure through natural air convection, preventing the internal equipment from being damaged due to overheating and ensuring the normal operation of the equipment. The connecting plate 23 at the bottom of the enclosure 21 is used to connect with the connecting structure 1 to ensure the stability of the overall structure. The protective sleeve 25 on the outer wall of the enclosure 21 protects the enclosure 21 from external physical impacts, further improving the damage resistance and service life of the shield.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
