Description

Technical Field

[0001] This invention relates to the field of cable connection protection devices, and in particular to a self-cleaning transparent insulating cover. Background Technology

[0002] In power transmission systems, cable connections are critical nodes, and their insulation performance and operating status directly affect the safety and stability of the entire power system. While existing cable insulation covers can provide basic insulation protection, they have many shortcomings in practical applications.

[0003] When used outdoors, the outer surface of the protective cover easily accumulates dust, sand, and other debris. In high-altitude areas, strong ultraviolet radiation accelerates the aging of the cover, significantly increasing the rate of dirt accumulation. In windy and sandy areas, high-speed airflow carrying particles continuously impacts the cover surface, exacerbating dirt accumulation and causing surface wear. This debris not only hinders direct observation of the connection points, making it impossible to detect potential problems such as overheating of joints and insulation aging in a timely manner, but may also generate additional stress due to snow and ice accumulation, leading to cover deformation, cracking, reduced insulation performance, and even serious accidents such as short circuits and grounding. Therefore, developing an insulating cover that combines self-cleaning, easy installation, long lifespan, and observability is of significant practical importance. Summary of the Invention

[0004] In order to overcome the shortcomings of existing cable insulation covers that are prone to dirt accumulation and difficult to clean and maintain, this invention provides a self-cleaning transparent insulation cover to achieve the purpose of automatically removing surface debris, simplifying installation operations, extending service life, and ensuring clear observation.

[0005] The technical solution of the present invention is as follows: a self-cleaning transparent insulating cover, comprising a cover, an insulating plug, a sealing ring, a first buckle ring, a clamp structure, a second buckle ring, a vibration structure, and a driving structure. At the connection end of two cables, the cover is installed at the connection end of one cable and the insulating plug is installed at the connection end of the other cable. Sealing rings for preventing moisture from entering are fixedly connected to both the front and rear ends of the cover. A first buckle ring is fixedly connected to the sealing ring at the rear end. A clamp structure is rotatably connected to both sides of the first buckle ring. A vibration structure is provided at the top of the cover. A second buckle ring is fixedly installed at the end of the insulating plug connected to the cover. A driving structure that cooperates with the vibration structure is provided at the top of the insulating plug.

[0006] As a preferred embodiment of the present invention, the vibration structure includes a movable member, a second spring, and an inclined block. The movable member is fixedly connected to the top of the protective cover. A movable groove for the inclined block to slide is provided inside the movable member. The inclined block is slidably connected to the movable member through the movable groove. A second spring is fixedly connected between the inclined block and the movable member. When the second spring is in its natural state, a part of the inclined block extends out of the movable member.

[0007] As a preferred technical solution of the present invention, the driving structure includes a rotating blade, a rotating shaft, and a fan blade. The top of the insulating plug is rotatably connected to the rotating shaft, the middle position of the rotating shaft is fixedly connected to the rotating blade, and the top of the rotating shaft is fixedly connected to the fan blade. The fan blade can drive the rotating shaft and the rotating blade to rotate together under the action of wind.

[0008] As a preferred embodiment of the present invention, the caliper structure includes a clamp, a moving rod, a first spring, and a limiting block. The clamps are rotatably connected to both sides of the first retaining ring. The moving rod is slidably passed through the front end of the clamp. The limiting block is rotatably connected to the end of the moving rod away from the clamp. The first spring is sleeved on the moving rod, and the two ends of the first spring are fixedly connected to the clamp and the limiting block, respectively. The first spring always applies a spring force to the limiting block in the direction away from the clamp.

[0009] As a preferred embodiment of the present invention, it further includes stabilizing rings. Stabilizing rings are fixedly connected to both the front and rear sides of the limiting block. The stabilizing rings are made of elastic material, which can enhance the fit between the limiting block and the first and second retaining rings.

[0010] As a preferred embodiment of the present invention, the protective cover is made of transparent insulating material, which allows for clear observation of the internal cable connections.

[0011] As a preferred embodiment of the present invention, the insulating plug is a frustum-shaped structure made of rubber, with its larger diameter end connected to the cable and its smaller diameter end facing the inside of the protective cover, so that the insulating plug and the protective cover fit more tightly and improve the sealing effect.

[0012] As a preferred technical solution of the present invention, the first buckle ring, the caliper structure and the second buckle ring together constitute a connection and fixing structure. When the first buckle ring and the second buckle ring are in contact with each other, the shape of the gap formed between them matches the shape of the limiting block in the caliper structure, ensuring that the limiting block can be accurately embedded therein, so as to achieve a stable connection.

[0013] As a preferred embodiment of the present invention, the rotating blade is composed of four blades, and each blade has an inclined surface on one side that cooperates with the inclined block. When the rotating blade rotates, the blade can interact with the inclined surface of the inclined block.

[0014] As a preferred embodiment of the present invention, the outer surface of the protective cover is coated with a wear-resistant layer. This wear-resistant layer is made of a transparent wear-resistant material, which can reduce wear on the surface of the protective cover and extend its service life.

[0015] The beneficial effects are:

[0016] 1. The present invention provides a vibration structure consisting of a moving part, a second spring and an inclined block at the top of the protective cover, and a driving structure consisting of a rotating blade, a rotating shaft and a fan blade at the top of the insulating plug. The wind energy drives the rotating blade to rotate and periodically triggers the vibration of the inclined block, thereby driving the protective cover to vibrate, achieving the effect of removing sand and dust, so as to reduce the maintenance cost of manual cleaning.

[0017] 2. This invention achieves multiple sealing protections at the cable connection points by setting sealing rings at both ends of the cover, combining the interference fit between the frustum-shaped rubber insulating plug and the cover, and the tight connection and fixing structure formed by the first buckle ring, the clamp structure and the second buckle ring, effectively preventing moisture and humidity from entering and improving insulation safety.

[0018] 3. This invention uses a transparent insulating material to make a protective cover, which, combined with a self-cleaning function, keeps the surface of the cover clean. This enables clear and visual observation of the operating status of the cable connection end, making it easier for operators to detect potential faults in a timely manner and improving maintenance efficiency.

[0019] 4. This invention, through the design of a caliper structure consisting of a clamp, a moving rod, a first spring, and a limiting block, combined with the quick docking of the first and second retaining rings and the stabilizing ring to enhance the tightness of the connection, achieves convenient installation and secure locking of the protective cover and the insulating plug, simplifies the operation process, and improves the reliability of the connection.

[0020] 5. This invention significantly improves the wear resistance of the protective cover surface by coating the outer surface with a wear-resistant layer made of polytetrafluoroethylene or nano-ceramic material, reducing the wear of the protective cover by wind and sand particles. At the same time, combined with the weather resistance of polycarbonate material itself, it extends the service life of the protective cover and reduces the replacement frequency and cost.

Detailed Implementation

[0030] The present invention will now be described in detail with reference to the accompanying drawings.

[0031] Example: A self-cleaning transparent insulating cover, such as Figures 1-8 As shown, it includes a protective cover 1, an insulating plug 2, a sealing ring 3, a first retaining ring 4, a clamping structure 5, a second retaining ring 9, a vibration structure, and a driving structure. At the connection end of the two cables, the protective cover 1 is installed at the connection end of one cable, and the insulating plug 2 is installed at the connection end of the other cable. The front and rear ends of the protective cover 1 are fixedly connected to the sealing ring 3 to prevent moisture from entering. The first retaining ring 4 is fixedly connected to the sealing ring 3 at the rear end. The clamping structure 5 is rotatably connected to the left and right sides of the first retaining ring 4. The top of the protective cover 1 is provided with a vibration structure. The end of the insulating plug 2 connected to the protective cover 1 is fixedly installed with the second retaining ring 9. The top of the insulating plug 2 is provided with a driving structure that cooperates with the vibration structure.

[0032] like Figures 7-8 As shown, the top of the protective cover 1 is fixedly connected to the movable part 6. The movable groove inside the movable part 6 allows the inclined block 8 to slide. The second spring 7 fixed between the inclined block 8 and the movable part 6 causes the inclined block 8 to extend out of the movable part 6 in its natural state. This structure allows the inclined block 8 to slide flexibly under the action of the rotating blade 10 and quickly return to its original position with the help of the second spring 7. Through repeated vibration, the snow, dust and other debris on the surface of the protective cover 1 are shaken off, ensuring that the surface of the protective cover 1 is clean and maintaining good light transmittance.

[0033] like Figures 7-8 As shown, the rotating shaft 11 connected to the top of the insulating plug 2 has a rotating blade 10 fixed in the middle and a fan blade 12 fixed at the top. The fan blade 12 drives the rotating shaft 11 and the rotating blade 10 to rotate under the action of wind. No additional power source is required. The rotating blade 10 can be driven to trigger the vibration structure to work by using natural wind energy, so as to realize the self-cleaning function of the protective cover 1, save energy and be suitable for various outdoor environments.

[0034] like Figures 4-5As shown, a movable rod 502 is slidably inserted through the front end of the clamp 501 rotatably connected to the left and right sides of the first buckle ring 4. The end of the movable rod 502 away from the clamp 501 is rotatably connected to the limiting block 504. The two ends of the first spring 503 sleeved on the movable rod 502 are fixed to the clamp 501 and the limiting block 504 respectively, and always apply an elastic force away from the clamp 501 to the limiting block 504. This structure allows the limiting block 504 to be tightly embedded in the gap between the first buckle ring 4 and the second buckle ring 9 under the action of the first spring 503, quickly completing the stable connection between the cover 1 and the insulating plug 2. The operation is convenient and the connection is reliable.

[0035] like Figures 4-5 As shown, the elastic material stabilizing rings 505 fixedly connected to the front and rear sides of the limiting block 504 can enhance the fit between the limiting block 504 and the first buckle ring 4 and the second buckle ring 9, reduce the gap at the connection, further improve the sealing and stability of the connection between the protective cover 1 and the insulating plug 2, and prevent water ingress or connection failure due to loosening.

[0036] like Figure 3 As shown, the protective cover 1 is made of transparent polycarbonate material, which allows operators to clearly observe the internal cable connection status, facilitates real-time monitoring of the operating status of the cable connection end, timely detection of possible faults, and reduces the operating risk of the power system. At the same time, the transparency does not affect the intuitive judgment of the internal condition of the protective cover 1.

[0037] like Figure 6 As shown, the larger diameter end of the truncated cone-shaped insulating plug 2 made of rubber is connected to the cable, and the smaller diameter end faces the inside of the protective cover 1, making the fit between the insulating plug 2 and the protective cover 1 tighter, effectively enhancing the sealing effect of the connection between the two, preventing moisture, dust and other substances from entering the inside of the protective cover 1, and protecting the cable connection end from external environmental corrosion.

[0038] like Figure 7 As shown, the first retaining ring 4, the clamp structure 5, and the second retaining ring 9 together constitute a connection and fixing structure. The shape of the gap formed when the first retaining ring 4 and the second retaining ring 9 come into contact matches the shape of the limiting block 504, ensuring that the limiting block 504 is accurately embedded. This design can quickly achieve precise docking and stable locking of the protective cover 1 and the insulating plug 2, improving installation efficiency and connection reliability.

[0039] like Figures 7-8 As shown, the four blades of the rotating blade 10 have an inclined surface on one side that cooperates with the inclined block 8. When the rotating blade 10 rotates, the blades can interact with the inclined surface of the inclined block 8, so that the inclined block 8 can slide smoothly under the push of the blades, ensuring the stable triggering of the vibration structure, ensuring that the protective cover 1 can continuously generate effective vibration to remove surface debris, and ensuring the stable operation of the self-cleaning function.

[0040] like Figure 3As shown, the outer surface of the protective cover 1 is coated with a wear-resistant layer made of polytetrafluoroethylene or nano-ceramic material, which can reduce the wear caused by wind, sun and dust friction on the surface of the protective cover 1 during long-term use, extend the service life of the protective cover 1, and at the same time, it does not affect the transparency and insulation performance of the protective cover 1.

[0041] When connecting two cables, first install the protective cover 1 on the connection end of one cable and the insulating plug 2 on the connection end of the other cable, then align and connect the connection ends of the two cables. Next, the operator holds the gripping end of the clamp 501 and pulls it inward, while the clamping end of the clamp 501 rotates outward around the hinge point. The clamp 501 drives the moving rod 502 and the limiting block 504 to rotate together, causing the limiting block 504 to disengage from the first retaining ring 4. At this time, the first spring 503 is stretched. When one end of the insulating plug 2 is inserted into the inside of the protective cover 1, and the first retaining ring 4 and the second retaining ring 9 are in contact with each other, the clamp 501 is released. Under the elastic force of the first spring 503, the limiting block 504 moves towards the first retaining ring 4 and the second retaining ring 9 and embeds itself in the gap between them. At the same time, the stabilizing ring 505 is compressed and deformed, tightly fitting against the surface of the first retaining ring 4 and the second retaining ring 9, thereby firmly connecting the protective cover 1 and the insulating plug 2 together. When the sealing rings 3 at both ends of the cover 1 are squeezed, they fit tightly against the surface of the cable, the cover 1, and the insulating plug 2, thus providing a good waterproof seal.

[0042] When snow, dust, or other dirt accumulates on the surface of the protective cover 1, the outside wind will cause the fan blade 12 to rotate. The fan blade 12 drives the rotating shaft 11 to rotate as well, and the rotating shaft 11 in turn drives the rotating blade 10 to rotate. During the rotation of the rotating blade 10, its blades will come into contact with the inclined block 8 in the vibration structure. Since both the blades and the inclined block 8 have inclined surfaces, the blades will exert a pushing force on the inclined block 8 towards the inside of the moving groove, causing the inclined block 8 to slide along the moving groove into the moving part 6. At this time, the second spring 7 is compressed. After the blades of the rotating blade 10 have rotated past the inclined block 8, the pushing force of the blades on the inclined block 8 disappears. Under the elastic force of the second spring 7, the inclined block 8 will quickly slide outward from the moving part 6 and return to its original position. The vibration generated by the inclined block 8 during the return process is transmitted to the protective cover 1, causing the dirt on the surface of the protective cover 1 to fall off under the vibration. This process is repeated as the rotating blade 10 continues to rotate, realizing the automatic cleaning function.

[0043] Because the cover 1 is made of transparent material and has a wear-resistant coating on its outer surface, it can maintain good light transmission at all times with the help of the self-cleaning function. Operators can clearly observe the operating status of the internal cable connection ends, detect potential faults in time, and greatly improve maintenance efficiency and the safety of the power system.

[0044] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
