Description

Technical Field

[0001] The utility model relates to the technical field of lightning protection metal nets, in particular to an installation structure of a lightning protection metal net for wind and lightning blades. Background Art

[0002] At present, all wind turbine blades include a lightning protection system. The lightning protection system is mainly composed of lightning rods set on the surface of the blade and wires inside the blade body. All lightning rods are connected to the wires. The wires are set at the root of the blade to interface with the entire machine. The lightning rods receive lightning and are connected to the lightning protection system of the entire machine through wires, thereby preventing the fiberglass reinforced plastic of the blade body from being struck by lightning. With the advancement of blade technology, especially the use of carbon fiber blades, metal mesh is increasingly used in blade lightning protection systems. By laying metal mesh on the surface of the blade, the metal mesh is connected to the main conductor of the lightning protection system through a down conductor, and when the blade is struck by lightning, the lightning current is guided to the lightning protection system of the wind turbine. However, the existing metal mesh installation structures are all fixed and welded, and are not easy to disassemble and repair after long-term use. Therefore, a metal mesh installation structure for wind and lightning blade lightning protection is proposed. The metal mesh is movably clamped by the cooperation of springs and clamps, which is easy to disassemble and quick to install. Utility Model Content
