Description

Technical Field

[0001] The utility model relates to the field of insulators, in particular to a multi-layered step-resistant pollution-resistant porcelain insulator. Background Art

[0002] Insulators are a special type of insulating control that plays an important role in overhead transmission lines. In the early years, insulators were mostly used on telegraph poles, and gradually developed into high-voltage power lines. Many disc-shaped insulators are hung on one end of the tower to increase the creepage distance. They are usually made of glass or ceramic.

[0003] A Chinese patent with announcement number CN220774047U discloses a multi-layer step-type anti-fouling porcelain insulator. The patent sets a scraper and uses wind energy to drive the scraper to rotate along the surface of the insulator to achieve the effect of scraping off stains on the surface of the insulator. However, the existing multi-layer step-type anti-fouling porcelain insulator uses external screws to fix the top seat and the cover plate when the wires are clamped and fixed. However, the screws are easily rusted or damaged due to long-term use and exposure to wind, water and sun, which is not conducive to later replacement. At the same time, when the existing technology clamps the wires, the clamping spacing is relatively fixed, making it difficult to fix wires of different thicknesses.

[0004] Therefore, the utility model provides a multi-layer step-resistant pollution-resistant porcelain insulator to solve the above-mentioned problem. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Example 1

[0033] This embodiment provides a multi-layer step-type pollution-resistant porcelain insulator, such as Figure 1-5 As shown, the multi-layer step-resistant porcelain insulator includes a fringe body 1, a chassis 12 arranged at the bottom of the fringe body 1, a connecting column 11 passing through the center position of the fringe body 1 and the chassis 12, a cleaning component 3 arranged on one side of the fringe body 1 for scraping stains on the surface of the fringe body 1, a top seat 4 installed on the top of the fringe body 1 for installing electric wires, and a cover plate 2 arranged on the top of the top seat 4, a slot for clamping the electric wires is opened between the top seat 4 and the cover plate 2, and the multi-layer step-resistant porcelain insulator also includes a limiting component 5 arranged on the top of the fringe body 1 for limiting the fringe body 1, the top seat 4 and the cover plate 2, the limiting component 5 includes slots 51 symmetrically opened on the top of the fringe body 1, the top seat 4 and the cover plate 2 and corresponding to each other, an insert block 52 slidably inserted in the slot 51, and a fixing component 53 respectively arranged on the fringe body 1 at positions on both sides corresponding to the top seat 4 and the cover plate 2 for fixing the insert block 52.

[0034] During use, the wires are first installed between the cover plate 2 and the top seat 4 to increase the creepage distance of the wires. During use, in order to avoid the external stains of the insulator body 1 affecting its use, the surface can be cleaned by the cleaning component 3. At the same time, in order to avoid the existing multi-layer step-resistant porcelain insulator, the top seat 4 and the cover plate 2 are fixed by installing external screws when the wires are clamped and fixed. However, the screws are easily rusted or damaged due to long-term use and exposure to wind, water and sun, which is not conducive to later replacement. The insulator body 1, the cover plate 2 and the top seat 4 can be limited by the limiting component 5. The plug block 52 is first slidably inserted into the slot 51. A sealing pad is provided on the top of the plug block 52 to prevent rainwater from flowing into the interior along the slot 51 and affecting later use.

[0035] Specifically, the fixing assembly 53 includes two installation boxes 536 fixedly arranged on the edge body 1 at positions on both sides of the top seat 4 and the cover plate 2 and corresponding to the two plug blocks 52, fixing holes 531 respectively opened on the slot 51, the plug block 52 and the installation box 536 near the plug block 52, a fixing rod 532 which moves laterally in the fixing hole 531 and is plugged into the fixing hole 531, a fixing spring 533 fixedly arranged on the fixing rod 532 away from the plug block 52 and fixedly connected to the inner wall of the installation box 536, a telescopic sleeve rod 534 arranged inside the fixing spring 533, a slideway 537 opened in the installation box 536 at a position corresponding to one side of the fixing spring 533, an L-shaped adjustment rod 535 fixedly arranged on the fixing rod 532 and slidably connected to the inside of the slideway 537, and a protective assembly 538 arranged at the outer side of the installation box 536 corresponding to the slideway 537 for protecting the L-shaped adjustment rod 535, the two ends of the telescopic sleeve rod 534 are respectively connected to the fixing rod 532 and the fixing spring The spring 533 is fixedly connected; after the insertion is completed, in order to prevent the position of the plug block 52 from being offset, the plug block 52 can be fixed by the fixing component 53, thereby fixing the flange body 1, the cover plate 2 and the top seat 4. When inserting the plug block 52, first move the L-shaped adjustment rod 535 along the slide 537 on the side of the installation box 536 to the side away from the plug block 52, thereby driving the fixing rod 532 to move out of the slot 51, so as to facilitate the insertion of the plug block 52 on the slot 51. After the insertion is completed, release the L-shaped adjustment rod 535. Adjust the rod 535. At this time, since the fixed spring 533 is elastic, the telescopic sleeve rod 534 inside it is composed of two rods, which can automatically retract and retract with the elastic adjustment of the fixed spring 533. The fixed spring 533 inside the installation box 536 drives the telescopic sleeve rod 534 to reset and squeeze the fixed rod 532 to penetrate the plug block 52 and the slot 51 and slide into the fixing hole 531, thereby achieving the fixation of the plug block 52 and the slot 51, thereby facilitating the fixation of the edge body 1, the cover plate 2 and the top seat 4.

[0036] Among them, in order to protect the L-shaped adjustment rod 535 and prevent it from being fixed by external pressure, the protection component 538 includes a protection box 5381 fixedly arranged on the outside of the installation box 536 and connected to the slide 537 for accommodating the L-shaped adjustment rod 535, and a closing plate 5382 hinged on the protection box 5381; protection can be performed by utilizing the protection component 538. When adjustment is required, the protection box 5381 is opened by rotating the closing plate 5382 to facilitate adjustment of the internal L-shaped adjustment rod 535. After the adjustment is completed, the closing plate 5382 is closed to seal the protection box 5381, thereby achieving the protection limit of the L-shaped adjustment rod 535.

[0037] Furthermore, in order to achieve timely cleaning of the surface of the rim body 1; the cleaning component 3 includes an annular groove 31 opened on the top of the rim body 1, an annular block 32 rotatably set inside the annular groove 31, an insulating plate 33 fixedly installed on the outside of the annular block 32, and a scraper 34 fixedly set between the insulating plate 33 and the rim body 1 and matching the curvature of the rim body 1; cleaning can be carried out through the cleaning component 3, and wind energy is converted into power. When wind blows, the scraper 34 is blown to make the annular block 32 move along the circumference of the annular groove 31, thereby driving the insulating plate 33 and the scraper 34 to rotate to scrape off the stains on the surface of the rim body 1, thereby achieving a reasonable cleaning effect.
