Description

Technical Field

[0001] The invention relates to the technical field of lightning protection devices, and in particular to a lightning protection device for a wind turbine generator set which is easy to install and disassemble. Background Art

[0002] The wind power source consists of a wind turbine generator set, a tower supporting the generator set, a battery charge controller, an inverter, a load unloader, a grid connection controller, a battery pack, etc. The wind turbine generator set includes a wind wheel and a generator; the wind wheel contains blades, a hub, reinforcements, etc.; it has the functions of blades rotating under wind power to generate electricity and the generator head rotating.

[0003] Lightning protection device refers to the sum of lightning rods, down conductors, grounding devices, surge protectors (SPDs) and other connecting conductors. Lightning protection devices can be divided into two categories: external lightning protection devices and internal lightning protection devices. External lightning protection devices are composed of lightning rods, down conductors and grounding devices, that is, traditional lightning protection devices; internal lightning protection devices are mainly used to reduce lightning currents and their electromagnetic effects inside buildings, such as adopting electromagnetic shielding, equipotential connection and installing surge protectors (SPDs) to prevent possible damage caused by lightning electromagnetic pulses. The grounding device is an important part of the lightning protection device. The grounding device discharges lightning current to the earth and limits the voltage of the lightning protection device to the ground from being too high. In addition to independent lightning rods, the lightning protection grounding device can be shared with other grounding devices on the premise that the grounding resistance meets the requirements.

[0004] Existing external wind turbines are generally protected from lightning by installing a lightning protection system. The current lightning protection system uses the traditional method of drawing lightning into the ground for lightning protection. This method has great safety hazards and extremely high cost investment; the lightning strike process can easily cause blades and lines to be directly struck by lightning and damaged, accompanied by greater safety risks; the induced current and lightning strike back generated by the lightning strike process cause impacts on wind turbine components, and batches of electrical components are often damaged; traditional lightning protection has high requirements for ground resistance, and a lot of cost is required for ground network transformation; after each lightning strike, a lot of manpower, devices, and time are spent on recovery. Summary of the invention

[0005] The object of the present invention is to provide a lightning protection device for a wind turbine generator set which is easy to install and disassemble, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: A lightning protection device for a wind turbine generator set that is easy to install and disassemble comprises a mounting base, a clamping assembly is movably mounted on the surface of the mounting base, a supporting assembly is fixedly mounted on the inner surface of the clamping assembly, an adjusting mechanism is fixedly mounted on the top of the mounting base, and a lightning protection mechanism is movably mounted on the surface of the clamping assembly; The mounting base includes a fixing unit and a mounting unit, and the mounting unit is fixedly mounted on the surface of the fixing unit; The adjusting mechanism comprises a driving unit and an adjusting unit, and the adjusting unit is fixedly mounted on the top surface of the mounting base.
