Description

Technical Field

[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 generally consists 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] For example, patent number CN202321174784.0 discloses a positioning tool for processing a wind turbine rotor, whose structure includes a bracket, and the bracket is arranged in four groups in a square shape, wherein the outer walls of two groups of the brackets are provided with motors, and the output end of the motor is fixedly connected to a first screw rod, and the first screw rod movably penetrates the inner side of one group of brackets and is rotatably connected to another group of brackets, and the first screw rod is threadedly sleeved with two groups of sliding blocks, and the top ends of the sliding blocks are fixedly connected to two groups of bearing seats, and a rotating roller is arranged between the two groups of bearing seats, and the support frame is provided with two groups, and the two ends of the support frame are fixedly mounted on the two groups On the outer wall of the bracket, an electric telescopic rod is fixedly installed in the middle of the bottom end of the support frame, and an arc-shaped positioning block is fixedly installed at the bottom end of the electric telescopic rod. The utility model inserts the fixing column into the hexagonal hole so that the rotating roller cannot rotate, and the two ends of the rotor are placed between the two sets of rotating rollers that cannot rotate, and then the electric telescopic rod drives the arc-shaped positioning block to press down the top positions of the two ends of the rotor, so that the wind turbine rotor is fixed. This fixing method is suitable for rotors of different sizes; when the rotor is rotated, the electric telescopic rod drives the arc-shaped positioning block to leave the rotor surface, and the two ends of the rotor will not collide with the rotating roller during the process;
