Description

Technical Field

[0001] This utility model relates to the field of rigid suspension insulator technology, specifically a rigid suspension insulator protection device. Background Technology

[0002] Rigid suspension insulators are a type of equipment used on power transmission lines. They are mainly used to support and fix conductors, while also providing insulation. Made of steel or composite materials, they have good mechanical strength and insulation properties, ensuring safe and stable power transmission.

[0003] Traditional rigid suspension insulator protection devices have many drawbacks. In terms of installation, they are usually unable to flexibly adjust their size, making it difficult to adapt to diameter differences at different installation locations. They also have low installation efficiency, poor structural stability, and lack of adjustable legs and fixing collars, making them prone to swaying and displacement in complex environments. In terms of protective performance, they cannot effectively block large particles and debris from the outside world, and the insulators are at high risk of corrosion, resulting in a short service life. Furthermore, in humid environments, the insulation performance of the insulators deteriorates due to water accumulation. Therefore, we propose a rigid suspension insulator protection device.

[0047] Limiting hole 17: It is opened at the top of the adjustment hole 16, evenly distributed and penetrating the top of the chassis 5, and cooperates with the positioning rod 4 to limit the position of the adjustment leg 2 within the chassis 5;

[0048] Positioning holes 18: Equally distributed on the top horizontal block of the adjusting leg 2, cooperating with the positioning rod 4, and corresponding to the limiting holes 17 of the chassis 5 to achieve precise adjustment of the adjusting leg.

[0049] Working Principle: The base 5 of this protective device has four circumferentially arrayed adjustable feet 2. The top horizontal block of each adjustable foot 2 has multiple equidistantly distributed positioning holes 18. The outer cylindrical surface of the base 5 has four centrally symmetrical, rectangular adjustment holes 16. The top of each adjustment hole 16 has multiple equidistant limiting holes 17, which penetrate the top of the base 5. During installation, the top horizontal block of the adjustable foot 2 is inserted into the adjustment hole 16. Positioning rods 4 are used to limit and fix the feet to the corresponding limiting holes 17 and positioning holes 18. Thus, depending on the diameter of the actual installation position, different combinations of limiting holes 17 and positioning holes 18 can be inserted by adjusting the positioning rods 4 to achieve the desired adjustment of the adjustable feet 2. The diameter of the base 5 is adjusted to ensure the entire protective device is in a horizontal and stable state. A fixing ring 1 is fitted onto the bottom of multiple adjusting legs 2. The fixing ring 1 consists of two mutually symmetrical, semi-circular fixing parts. A placement block 3 is fixed to the end of each adjusting leg 2. The two fixing parts form a complete ring fitted onto the placement block 3 at the end of the multiple adjusting legs 2. The fixing ring 1 not only further stabilizes the bottom of the adjusting legs 2, preventing them from shaking or shifting during use, but also enhances overall stability. Four symmetrical support columns 14 are fixed to the bottom of the mounting base 6. The ends of the support columns 14 are threaded. A through connecting hole 15 is provided on the top of the base 5, and the connecting hole 15 is symmetrical about the four central axes. The support columns are symmetrically distributed. During installation, the ends of the support columns 14 are inserted into the corresponding connecting holes 15, and then fixed with nuts corresponding to the external threads at the ends of the support columns 14. This ensures a stable connection between the mounting base 6 and the base plate 5, providing a reliable foundation for the subsequent installation of insulators and protective structures. The right protective cover 7 and the left protective cover 8 are symmetrically arranged and identical, forming a complete cylinder. Symmetrical connecting plates 11 are fixed to the outer sides of the top and bottom ends of the left protective cover 8. The connecting plates 11 have a threaded hole. The top of the mounting base 6 is fixed with a circular connecting ring 13. The cylinder formed by the right protective cover 7 and the left protective cover 8 is fitted onto the connecting ring 13. At the same time, the mounting base 6 and the protective top plate 9 each have a threaded hole. The bolts are threaded into threaded holes one and two, respectively, to fix the two ends of the right protective cover 7 and the left protective cover 8 to the mounting base 6 and the protective top plate 9, thereby completely enclosing the insulator 10 inside the cylinder. This effectively blocks large particles and debris from corroding the insulator. The left protective cover 8 consists of multiple equally spaced drainage blocks 12. The interior of the drainage blocks 12 is fixed by connecting columns, and the cross-section of the drainage blocks 12 is inclined. When rainwater or other liquids enter the protective cover, the liquid will flow to the bottom along the inclined surface of the drainage blocks 12 under the action of the inclined drainage blocks 12, ensuring that the insulation performance is not affected by water accumulation around the insulator, and ensuring that it can work stably in a humid environment.
