Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation equipment, and more specifically, to a lightning protection grounding mechanism for wind power generation equipment. Background Art

[0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind energy is a clean, pollution-free, renewable energy source that has been used by people for a long time, mainly through windmills to pump water, grind flour, etc. People are interested in how to use wind to generate electricity. Wind power generation is very environmentally friendly and has huge wind energy reserves. Therefore, it is increasingly valued by countries around the world. In thunderstorms, lightning can easily strike wind power generation equipment, causing damage to the wind power generation equipment. Therefore, lightning protection and grounding mechanisms are installed on existing wind power generation equipment.

[0003] The existing wind power generation equipment uses a lightning protection grounding mechanism to connect the lightning rod on the wind power generation equipment to the grounding plate through a cable. Since the wind power generation equipment will rotate accordingly according to different wind directions during operation, the cables will become entangled during the rotation of the wind power generation equipment. In addition, since the fan blades are relatively long, in order to ensure the lightning protection effect, the top of the lightning rod needs to be located on the upper side of the fan blade rotation range. Therefore, the lightning rod needs to be relatively long. When the wind is strong, the lightning rod is prone to shaking, bending and damage. Utility Model Content
