Description

Technical Field

[0001] The utility model relates to the technical field of lightning protection and grounding, in particular to a lightning protection and grounding device for a municipal wind turbine generator. Background Art

[0002] In municipal planning and construction, in order to reduce the resource consumption of thermal power generation and increase the supply of electricity, wind turbines may be set up in open areas to provide electricity. Wind turbines are power equipment that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. Wind turbines are generally composed of wind wheels, generators, direction regulators, towers, speed limit safety mechanisms and energy storage devices. Lightning protection and grounding are divided into two concepts, one is lightning protection to prevent damage caused by lightning strikes, and the other is electrostatic grounding to prevent harm caused by static electricity. With the increasing application of cathodic protection of storage tanks, its protection effect has attracted more and more attention, and the contradiction between lightning protection grounding specifications and cathodic protection specifications has become more and more prominent. Lightning protection grounding devices can also be expressed as lightning rods.

[0003] For example, the Chinese patent with publication number CN210984987U proposes a lightning protection and grounding device for a wind turbine generator. The patent sets a No. 1 lightning strip and a No. 2 lightning strip to be sleeved on the outside of the wind turbine cabin so that the No. 1 fixing plate is aligned with the No. 2 fixing plate, and bolts are passed through the No. 1 fixing plate and the No. 2 fixing plate and fixed by nuts, so that the No. 1 lightning strip and the No. 2 lightning strip are fixed to the outside of the wind turbine cabin, and the fixation is relatively firm, which solves the problem of inconvenient installation of the lightning strip on the smooth surface of the wind turbine cabin; the internal thread fixing tube is screwed on the outside of the lower threaded tube, and the lower end of the upper threaded tube is aligned with the lower threaded tube. The upper end of the device is connected, and the internal threaded fixing tube is rotated upward to the connection between the lower threaded tube and the upper threaded tube, so that the lower threaded tube and the upper threaded tube are fixed, thereby connecting the grounding wire and the down conductor. The installation and disassembly are relatively convenient, and the grounding wire and the down conductor are easy to carry after being disassembled. The effect is better than the traditional method. However, in this scheme, since the lightning rod in the device is exposed to the outdoor environment and the wind turbine is relatively high, the No. 1 lightning strip and the No. 2 lightning strip need to be at a higher position of the wind turbine. When strong winds occur at a higher position, the lightning rod may shake and break, which may affect the lightning protection effect of the wind turbine. Utility Model Content

[0029] Working principle: Please refer to Figure 1-Figure 6As shown, through the support ring 7, the staff places the placement tube 6 into the placement groove 5, and then inserts the support ring 7 into the placement tube 6. At this time, the staff turns on the servo motor 12 through the PLC controller 2, and the servo motor 12 drives the shaft to rotate to drive the winding column 13 to rotate, thereby pulling and winding the steel cable 14, so that the steel cable 14 is in a straight state. At this time, the two steel cables 14 pull the support ring 7, and then support the placement tube 6, and then support the lightning rod body 4, thereby achieving the effect of supporting the lightning rod body 4, preventing the lightning rod body 4 from shaking, which makes the lightning protection effect of the lightning rod body 4 poor.

[0030] By means of the provided clamping block 19, when the staff needs to adjust the position of the support ring 7, the staff slides the support ring 7 to make the slide bar 16 slide in the slide groove 15. At this time, the spring 18 is squeezed and then rebounds to make the clamping block 19 move in the installation groove 17 and clamp into the clamping groove 22 to limit the support ring 7, thereby achieving the effect of stable placement after the position of the support ring 7 is adjusted. The bearing 20 makes the winding column 13 more stable during rotation. When the staff places the placement tube 6 into the placement groove 5, the staff rotates the bolt 24 so that the bolt 24 passes through the threaded hole 23 and is rotated into the placement groove 5 to squeeze and limit the placement tube 6, thereby preventing the placement tube 6 from shaking in the placement groove 5. The gasket 25 is used to prevent the bolt 24 from slipping when it is rotated into the threaded hole 23 to squeeze and limit the placement tube 6.
