Description

Technical Field

[0001] This utility model belongs to the field of insulator technology, and particularly relates to a fiberglass column insulator. Background Technology

[0002] Fiberglass reinforced plastic (FRP) column insulators are column-type insulating devices made primarily of FRP. They are mainly used in high-voltage transmission lines, substations, and special environments to provide electrical insulation and mechanical support. Their core characteristics include excellent corrosion resistance, strong resistance to atmospheric and water oxidation, and resistance to various solvents such as acids, alkalis, and salts of general concentrations. They are lightweight, have high mechanical strength, yet their tensile strength is close to or even exceeds that of carbon steel. They also possess excellent insulation performance, maintaining good dielectric properties even at high frequencies. Damage can be visually identified; when there is internal flashover or damage to the surge arrester, the damage point can be visually observed. Furthermore, their smooth surface and superior hydrophobicity, surpassing silicone rubber and porcelain, ensure long-term outdoor operation, allowing rain and snow to drain away promptly.

[0003] The following problems exist with the application of fiberglass post insulators currently on the market:

[0004] 1. When cleaning traditional fiberglass column insulators, the insulator body is usually directly exposed to the outside. In order to avoid dust adhering to the surface of the insulator and causing short circuits, the surface of the insulator body needs to be cleaned regularly by the staff, which is inconvenient.

[0005] 2. Most fiberglass column insulators require fasteners to connect and fix the insulator body during use. These fasteners are exposed to the air for a long time and are prone to corrosion. Therefore, they do not have a protective structure during use. Utility Model Content

The top of the insulator body is provided with a steel cap, and the bottom of the insulator body is provided with a steel foot. The outside of the insulator body is provided with clamping rings, which are symmetrically distributed. The bottom of the clamping rings is connected to a fixing plate. An arc-shaped groove is opened inside the fixing plate. A spherical tie rod is embedded inside the arc-shaped groove. The bottom of the spherical tie rod is provided with a fixing block. The bottom of the fixing block is connected to a protective sleeve. A cleaning plate is installed inside the protective sleeve.

[0028] To better understand the purpose, structure, and function of this utility model, a fiberglass column insulator of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] like Figure 1-5 As shown, this utility model discloses a fiberglass column-type insulator, comprising an insulator body 1 and a steel cap 20. The top of the insulator body 1 is provided with a steel cap 20, and the bottom of the insulator body 1 is provided with a steel foot 21. The outside of the insulator body 1 is provided with a clamping ring 2, which is symmetrically distributed. The bottom of the clamping ring 2 is connected to a fixing plate 3. The inside of the fixing plate 3 is provided with an arc-shaped groove 4. Due to the arc-shaped groove 4, it is convenient for the operator to pull the ball to move inside the fixing plate 3. The inside of the arc-shaped groove 4 is embedded with a spherical pull rod 5. The bottom of the spherical pull rod 5 is provided with a fixing block 10. The bottom of the fixing block 10 is connected to a protective sleeve 6. A cleaning plate 9 is installed inside the protective sleeve 6. By providing a clamping ring 2 and a fixing plate 3 on the outside of the insulator body 1, slidingly connecting the protective sleeve 6 inside the fixing plate 3, and installing a cleaning plate 9 inside the protective sleeve 6, before cleaning, it is first checked whether the fasteners have installed the cleaning structure on the outside of the body. After checking, the operator can hold the spherical handle and rotate the cleaning plate 9 inside the protective sleeve 6.

[0030] The steel foot 21 is equipped with a steel cap 20 on the outside, and a cover 14 is provided on the outside of the steel cap 20. An arc frame 15 is connected inside the cover 14, and a drying sheet 16 is provided inside the cover 14. A positioning rod 17 is provided at the bottom of the cover 14. The positioning rod 17 is embedded in the outside of the insulator body 1. By installing the cover 14 on the outside of the steel cap 20, and installing the arc frame 15 and the mesh plate 19 inside the cover 14, and embedding the drying sheet 16 inside the mesh plate 19, after the insulator equipment is installed, the workers can take out the drying sheet 16 and install it inside the cover 14, and then install the cover 14 on the outside of the insulator body 1. In this way, the fasteners can be protected.

[0031] The side of the clamping ring 2 is connected to the mounting plate 11, which is symmetrically distributed. The inside of the mounting plate 11 is through the threaded post 12, and the outside of the threaded post 12 is connected to the nut 13. Because of the mounting plate 11, the threaded post 12 and the nut 13, it is convenient to use fasteners to fix the clamping ring 2 to the outside of the insulator body 1.

[0032] The protective cover 6 has a metal groove 7 inside, and the top of the cleaning plate 9 is provided with a magnetic plate 8. The magnetic plate 8 is embedded inside the metal groove 7. Because of the magnetic plate 8 and the metal groove 7, the protective cover 6 and the cleaning plate 9 can be easily assembled by magnetic attraction.

[0033] A positioning groove 18 is provided on the top of the insulator body 1, and a positioning rod 17 is embedded inside the positioning groove 18. Due to the positioning groove 18, it is convenient to install the cover 14 on the outside of the insulator body 1.

[0034] The inner side of the arc frame 15 is inlaid with a mesh plate 19. There are two sets of mesh plates 19. The installation of mesh plates 19 facilitates the drying sheet 16 to absorb the moisture inside the cover 14, thus slowing down the corrosion of fasteners.

[0035] The working principle of this fiberglass column insulator is as follows: First, the device body needs to be moved to the designated position and placed on a flat surface. To facilitate external dust cleaning of the insulator body 1 at high altitudes, a clamping ring 2 and a fixing plate 3 are installed on the outside of the insulator body 1. An mounting plate 11 is connected to the outside of the clamping ring 2. Threaded posts 12 and nuts 13 are installed inside the mounting plate 11. A protective sleeve 6 is slidably connected inside the fixing plate 3. A metal groove 7 is formed inside the protective sleeve 6, and a cleaning plate 9 is installed inside the protective sleeve 6. A magnetic suction plate 8 is connected to the top of the cleaning plate 9, and a ball-shaped tie rod 5 is installed on the top of the protective sleeve 6. Before installing the insulator, the operator first needs to install the clamping ring 2 on both sides of the insulator body 1 and then tighten the nuts 13 on the outside of the threaded posts 12 for a fixed connection. This allows the cleaning structure to be installed on the outside of the insulator body 1. Then, a crane is used to lift it up, and it is installed on the outside of the cable. To prevent moisture from affecting the fastening... To prevent corrosion, a cover 14 is installed on the outside of the steel cap 20, and an arc frame 15 and a mesh plate 19 are installed inside the cover 14. A drying sheet 16 is embedded inside the mesh plate 19. After the insulator equipment is installed, the operator removes the drying sheet 16 and installs it inside the cover 14. Then, the cover 14 is installed on the outside of the insulator body 1. The bottom of the cover 14 is provided with a positioning rod 17, and the top of the insulator body 1 is provided with a positioning groove 18. The positioning rod 17 is embedded inside the positioning groove 18. This can protect the fasteners and achieve the effect of drying the environment during use. However, when it is necessary to clean the outside of the insulating terminal, first check whether the fasteners have installed the cleaning structure on the outside of the body. If they are loose, they can be tightened with a fastening tool. After checking, the operator holds the ball handle and rotates the cleaning plate 9 inside the protective sleeve 6. This can remove the dust from the outside of the insulator body 1. The cleaning operation is relatively simple, and the dust generated during cleaning will be blown away by the wind.
