Description

Technical Field

[0001] The utility model relates to a blade position detection structure for wind power generation equipment, in particular to a blade position detection structure for wind power generation equipment, belonging to the technical field of blade position detection. Background Art

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. A wind turbine is generally composed of a wind rotor, a generator (including a device), a stabiliser (tail), a tower, a speed limit safety mechanism and an energy storage device. The working principle of a wind turbine is relatively simple. The wind rotor rotates under the action of wind force, and it converts the kinetic energy of the wind into the mechanical energy of the wind rotor shaft. The generator rotates and generates electricity under the drive of the wind rotor shaft. In a broad sense, wind energy is also solar energy, so it can also be said that a wind turbine is a heat energy generator that uses the sun as a heat source and the atmosphere as a working medium.

[0003] Since the blades of wind turbines are large and installed at a high position, it is very troublesome to install the blades on site. The accuracy of the blade installation position is determined by the on-site staff through visual identification. However, the naked eye has limited ability to distinguish, so the blades are fixed and installed in a tilted state, which makes the blades difficult to install. After the installation is completed, it will affect the normal use of the blades and the service life of the blades. Utility Model Content
