Machine head positioning device for wind generator

Abstract

The invention relates to the technical field of wind generation and particularly relates to a machine head positioning device for a wind generator. The machine head positioning device comprises a tower column and a hand piece, wherein the machine head is arranged above the tower column; a cylinder is vertically fixed at the top end of the tower column; an annular guide rail is arranged on the sidesurface, far away from the tower column, of the cylinder, a connecting rod is arranged in the cylinder and is vertically fixed on the tower column; a pivotal bearing sleeves the top end, far away from the tower column, of the connecting rod, a groove is formed in the side surface, close to the tower column, of the machine head, and the pivotal bearing is fixedly arranged in the groove; and fixedseats are fixed on the machine head on two sides of the pivotal bearing, and pulleys are connected to the fixed seats through rotating shafts. The machine head positioning device is simple in structure and convenient to operate; and the machine head can be limited while not rotating, so that the machine head of the wind generator is deviated from the wind direction under the wind action.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a nose positioning device of a wind power generator. Background technique [0002] A wind turbine is an electrical device that converts wind energy into mechanical energy and mechanical energy into electrical energy. Broadly speaking, it is a thermal energy utilization engine that uses the sun as the heat source and the atmosphere as the working medium. Wind power utilizes natural energy. Wind power cannot be regarded as a backup power source, but it can be used for a long time. The principle of wind power generation is to use the wind to drive the blades of the windmill to rotate, and then increase the speed of rotation through the speed increaser to drive the generator to generate electricity. [0003] With the development of wind power generators, in order to generate wind power with higher efficiency, people usually install a steering device on the nose to ca...

AI Technical Summary

Problems solved by technology

[0003] With the development of wind power generators, in order to generate wind power with higher efficiency, people usually install a steering device on the nose to capture the wind direction, but due to the uncertainty of the wind direction, it will cause the nose to swing, and the long-term Swing will cause the wear of the machine head and reduce the service life of the machine head, so a wind turbine head positioning device is needed to position the machine head when the machine head does not need to rotate
