Description

Technical Field

[0001] This invention relates to the field of insulator technology, specifically to a tension porcelain insulator for power transmission lines. Background Technology

[0002] An insulator is a device installed between conductors at different potentials or between a conductor and a grounding component, capable of withstanding voltage and mechanical stress. Insulators come in many types and shapes. Although different types of insulators vary considerably in structure and appearance, they all consist of two main parts: insulating components and connecting hardware. An insulator is a special type of insulating control that plays a crucial role in overhead transmission lines. In the early days, insulators were mostly used on utility poles. Gradually, they evolved into the use of disc-shaped insulators hung at one end of high-voltage power line towers to increase creepage distance. These are typically made of glass or ceramic and are called insulators. Insulators should not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions; otherwise, they will not function effectively and will damage the service life and operational life of the entire line.

[0003] An insulator is a device installed between conductors at different potentials or between a conductor and a grounding component, capable of withstanding voltage and mechanical stress. Insulators come in many types and shapes. Although different types of insulators vary considerably in structure and appearance, they all consist of two main parts: insulating components and connecting hardware. An insulator is a special type of insulating control that plays a crucial role in overhead transmission lines.

[0004] However, existing transmission line tension porcelain insulators suffer from uneven stress during installation because the steel feet are difficult to fix stably on the central axis of the insulator, causing the steel feet to become eccentric. This eccentricity leads to uneven stress on the insulator during use, causing it to shift and affecting the product's service life. Summary of the Invention

[0005] The purpose of this invention is to provide a tensioning porcelain insulator for power transmission lines to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tensioning porcelain insulator for transmission lines, comprising an insulator, wherein a fixing component and a protective component are provided at the bottom of the insulator. The protective component can be used to improve the stability of the steel feet on the central axis of the insulator during installation, preventing the steel feet from becoming eccentric. The protective component includes: a fixing rod, which is fixedly installed at the bottom of the insulator. A fixing block is slidably connected to the surface of the fixing rod. A fixing shaft is fixedly installed at the bottom of the fixing block. A support rod is fixedly installed at the bottom of the fixing shaft.

A connecting rod is fixedly installed inside the sliding block. A slider is slidably connected to the surface of the connecting rod. The slider is slidably connected to the surface of the connecting rod. A hinge rod is slidably connected inside the slider. The hinge rod is hinged to the bottom of the fixed shaft. A limiting plate is hinged to the bottom of the hinge rod and slidably connected to the inside of the base plate. This causes the insulator to shift, greatly improving the service life of the insulator and enhancing its practicality. The protective component also includes a protective element, which can effectively protect the insulator when it shifts, thus strengthening its protection.

[0007] Preferably, the protective component includes: a movable rod one, which is hinged to the surface of the fixed shaft, a torsion spring is fixedly installed on the inner side of the movable rod one, and a movable rod two is fixedly installed on the outer side of the torsion spring, and the movable rod two is hinged to the surface of the fixed shaft.

[0008] Preferably, a connecting block is fixedly installed on the top of the sliding block, a connecting plate is fixedly installed on the top of the connecting block, and a push block is fixedly installed on the top of the connecting plate.

[0010] Preferably, the fixing component includes: a short rod, which is fixedly installed at the bottom of the fixing rod, a limit block is slidably connected to the surface of the short rod, a top block is fixedly installed at the bottom of the short rod, one end of a fixing spring is fixedly installed at the top of the limit block, and the other end of the fixing spring is fixedly installed at the bottom of the fixing rod.

[0012] Preferably, the cross-section of the slider is rectangular. The rectangular slider can slide on the surface of the connecting rod and can also drive its hinge rod to move. When the hinge rod moves, it drives the bottom limiting plate to move.

[0013] Preferably, the limiting plate has an insertion hole inside, which allows the insertion rod to slide inside the limiting plate, thus restricting the movement of the limiting plate and enhancing stability.

[0014] Preferably, the base plate has a sliding groove inside, which can drive the limiting plate to slide inside the base plate, thereby increasing the force-bearing area of ​​the insulator during installation.

[0016] Beneficial effects:

The protective component 3 can be used to improve the stability of the steel feet of the insulator 1 during installation, preventing eccentricity of the steel feet. The protective component 3 includes a fixing rod 31, which moves when the insulator 1 is in use. When the fixing rod 31 moves, it moves a short rod 21 at the bottom. When the short rod 21 moves, it moves the limiting block 22 and the top block 23 on its surface. When the short rod 21 slides into the fixing block 32, ... When the top block 23 abuts against its limiting rod 25, and the limiting rod 25 is reset under the action of the fixed spring 26, it is inserted into the surface of the short rod 21 for limiting. When the short rod 21 abuts against its limiting rod 25 using the limiting block 22, the limiting block 22 will abut against the movement of its limiting rod 25. The fixed rod 31 is fixedly installed at the bottom of the insulator 1. The fixed block 32 is slidably connected to the surface of the fixed rod 31.

A connecting rod 39 is fixedly installed inside the sliding block 37. When the connecting rod 39 moves, it drives the movement of its insertion rod 47. When the insertion rod 47 slides inside the limiting plate 312, a slider 310 is slidably connected to the surface of the connecting rod 39. The slider 310 is slidably connected to the surface of the connecting rod 39. A hinge rod 311 is slidably connected inside the slider 310. The hinge rod 311 is hinged to the bottom of the fixed shaft 34. The limiting plate 312 is hinged to the bottom of the hinge rod 311 and slidably connected to the inside of the base plate 36, thereby causing the insulator 1 to shift, greatly improving the service life of the insulator 1 during use and enhancing the practicality of the insulator 1. The protective component 4 is also included in the protective assembly 3. The protective assembly can be used to... The protective component 4 within component 3 effectively protects the insulator 1 when it shifts, while simultaneously strengthening the protection of the insulator 1. The protective component 4 includes: a first movable rod 41, which, when the insulator 1 shifts, is abutted by a top block 23 against either the first movable rod 41 or the second movable rod 43. When the first movable rod 41 and the second movable rod 43 move, they abut against a push block 46. When the push block 46 moves, it abuts a sliding block 37. When the sliding block 37 moves, it abuts a connecting rod 39. When the connecting rod 39 moves, it abuts a slider 310 on its surface. When the slider 310 moves, it abuts a hinge rod 311 at its bottom. When the hinge rod 311 moves, it abuts a limiting plate 312. The first movable rod 41 is hinged to the surface of the fixed shaft 34, and a torsion spring 42 is fixedly installed inside the first movable rod 41.A movable rod 43 is fixedly installed on the outer side of the torsion spring 42, and the movable rod 43 is hinged to the surface of the fixed shaft 34. A connecting block 44 is fixedly installed on the top of the sliding block 37, a connecting plate 45 is fixedly installed on the top of the connecting block 44, and a push block 46 is fixedly installed on the top of the connecting plate 45. An insert rod 47 is fixedly installed at the bottom of the connecting rod 39, and the insert rod 47 is slidably connected to the inside of the limiting plate 312, which improves the protective effect of the insulator 1 and greatly enhances its service life and effectiveness. The fixing component 2 includes a short rod 21, which is fixedly installed at the bottom of the fixing rod 31. A limit block 22 is slidably connected to the surface of the short rod 21, and a top block 23 is fixedly installed at the bottom of the short rod 21. One end of a fixing spring 24 is fixedly installed on the top of the limit block 22, and the other end of the fixing spring 24 is fixedly installed at the bottom of the fixing rod 31. The fixing component 2 facilitates the installation and disassembly of the insulator 1 during maintenance and replacement, greatly improving the convenience for workers. A limiting rod 25 is slidably connected inside the fixing block 32. A fixing spring 26 is fixedly installed on the surface of the limiting rod 25 and is fixedly installed inside the fixing block 32. This increases the efficiency of workers when replacing and repairing the insulator 1, improves the convenience of insulator 1 during maintenance and replacement, and reduces the difficulty of the work. The slider 310 has a rectangular cross-section. The rectangular slider 310 can slide on the surface of the connecting rod 39 and can also drive the hinge rod 311 to move. When the hinge rod 311 moves, it drives the bottom limiting plate 312 to move. The limiting plate 312 has an insertion hole inside. The insertion hole inside the limiting plate 312 can drive the insertion rod 47 to slide inside the limiting plate 312, limiting the movement of the limiting plate 312 and thus enhancing stability. The bottom plate 36 has a sliding groove inside. The sliding groove inside the bottom plate 36 can drive the limiting plate 312 to slide inside the bottom plate 36, thereby increasing the force-bearing area of ​​the insulator 1 during installation.

[0026] Working principle: When insulator 1 is in use, it can drive the movement of its bottom fixed rod 31. When the fixed rod 31 moves, it drives the movement of its bottom short rod 21. When the short rod 21 moves, it drives the movement of its surface limiting block 22 and top block 23. When the short rod 21 slides into the fixed block 32, its top block 23 abuts against its limiting rod 25. When the limiting rod 25 is reset under the action of the fixed spring 26, it is inserted into the surface of the short rod 21 for limiting. When the short rod 21 abuts against its limiting rod 25 using the limiting block 22, the limiting block 22 will abut against the movement of its limiting rod 25, thereby releasing the limitation of the limiting rod 25 on the surface of the short rod 21, thus releasing... In addition to limiting the position, it facilitates the installation and disassembly of insulator 1 during maintenance and replacement, greatly improving the convenience for workers and increasing the efficiency of insulator 1 maintenance and replacement. It also reduces the difficulty of the work. When insulator 1 is installed, if it shifts, the top block 23 will abut against either movable rod 41 or movable rod 43. When movable rods 41 and 43 move, they will abut against the push block 46. When the push block 46 moves, it will move the sliding block 37. When the sliding block 37 moves, it will move the connecting rod 39. When the connecting rod 39 moves... The movement of the slider 310 on its surface allows the rectangular slider 310 to slide on the surface of the connecting rod 39 and also drives the hinge rod 311 to move. When the hinge rod 311 moves, it drives the bottom limiting plate 312 to move. The sliding slider 310 moves, which in turn drives the bottom hinge rod 311 to move. When the hinge rod 311 moves, it drives the limiting plate 312 to move. The insertion hole inside the limiting plate 312 allows the insertion rod 47 to slide inside the limiting plate 312, limiting the movement of the limiting plate 312 and thus enhancing stability. When the limiting plate 312 moves, it improves the stability of the insulator 1, preventing the steel feet from being stably fixed in the middle of the insulator 1 during installation. On the axis, to prevent the steel foot from becoming eccentric and causing the insulator 1 to shift, the service life of the insulator 1 is greatly improved and its practicality is enhanced. When the connecting rod 39 moves, it drives the movement of its insertion rod 47. When the insertion rod 47 slides inside the limiting plate 312, the sliding groove inside the base plate 36 can drive the limiting plate 312 to slide inside the base plate 36, thereby increasing the force-bearing area of ​​the insulator 1 during installation and effectively protecting it from shifting. While protecting it, the protection force of the insulator 1 is enhanced, improving the protection effect of the insulator 1, and also greatly improving the service life and effectiveness of the insulator 1.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
