Description

Technical Field

[0001] The utility model relates to the technical field of lightning protection equipment for high-voltage power transmission lines, and more specifically, to an adjustable lightning protection installation device for overhead power transmission lines. Background Art

[0002] An overhead transmission line lightning arrester, also known as a lightning arrester or lightning protector, is a device used to protect overhead transmission lines from lightning strikes. Its function is to set up a distributed capacitor at certain places in the power system to transfer overvoltages that exceed the system voltage level to the ground to protect other equipment and facilities in the line. The existing adjustable lightning protection installation device for overhead transmission lines, when assembled, needs to first remove the line insulator, then fix the insulator and the hardware with connecting bolts, and finally install the insulator and the hardware on the crossarm with connecting bolts. During installation, it is necessary to loosen or remove components on the line, and the components on the line are not easy to loosen or remove due to rust, which will cause damage to the original components on the transmission line. At the same time, the installation structure is complicated, not convenient for quick assembly, and the force effect is poor, lacking stability and safety.

[0003] After searching, a Chinese patent with publication number CN205355766U discloses an adjustable lightning protection installation device for overhead power transmission lines. The structure can realize clamping support for cross arms of different types (such as angle steel cross arms and flat steel cross arms) by arranging a clamping component on one side of the main support plate, and the support effect is good, the installation is stable and reliable, and it is easy to install quickly.

[0004] However, when this structure is actually used, since the lightning arrester needs to be connected in parallel with the protected equipment when in use, and during the parallel connection process, there is often a shortage of connecting wires. Since the existing device is fixed and cannot be adjusted in position, the shortage of wires cannot be quickly resolved. Utility Model Content

[0010] Through the above scheme, it can be seen that by setting a fixed rod and a movable rod on one side of the slider, and setting a compression spring on the outside of the fixed rod and the movable rod, the compression spring can be loosened by controlling the position of the limit knob, and then the compression spring drives the support plate to move horizontally, thereby realizing the position adjustment of the lightning arrester and improving the practicability of the device.

[0011] Technical effects and advantages of the utility model:

[0012] 1. By setting a lifting and adjusting component, a limiting protrusion is set on one side of the mounting plate, and then the lifting function of the slider is realized by connecting the slider with the limiting protrusion. At the same time, the support plate is set on one side of the slider, and then the support plate is driven to move up and down by the movement of the slider, and then the lightning arrester at the bottom of the support plate is driven to adjust its position to make up for the lack of wires, thereby improving the practicality of the device;

[0013] 2. By setting up a lateral adjustment component, compared with the prior art, a fixed rod and a movable rod are set on one side of the slider, and compression springs are set on the outside of the fixed rod and the movable rod.
