Abstract

The invention provides a wind power blade root anti-shrinkage device, and relates to the technical field of wind power blade manufacturing. The wind power blade root anti-shrinkage device comprises asupport, supporting feet, mounting arms, a mounting disc and a center shaft mounted on the support. The mounting arms are arranged on the periphery of the mounting disc. The supporting feet connectedwith blade roots in an abutting manner are hinged to the mounting arms. The supporting feet are mounted on the support and move in the radial direction of the blade root circle. The mounting disc is mounted on the center shaft in a sleeving manner and moves in the axial direction of the center shaft. A limiting part for limiting the position of the mounting disc is arranged on the center shaft. The invention further provides an application method of the device. After the blade roots are placed in the wind power blade root anti-shrinkage device, the supporting feet are adjusted manually and arein contact with the inner walls of the blade roots, the position of the mounting disc on the center shaft is adjusted, and the mounting arm drives the supporting feet to move in the radial directionof the blade root circle till the supporting feet are connected with the inner walls of all the blade roots in the abutting manner. The wind power blade root anti-shrinkage device is stable in structure, convenient to operate and high in practicality, anti-shrinkage treatment can be carried out on the blade roots of various different types, and the blades cannot be damaged.

Description

technical field [0001] The invention relates to the technical field of wind power blade manufacturing, in particular to a wind power blade root shrinkage prevention device and a use method. Background technique [0002] The shortage of fossil energy will eventually lead to depletion, prompting countries all over the world to vigorously develop renewable wind energy. The way to realize it is to use the wind generator to drive the wind wheel to rotate, and drive the wind generator to generate electricity or do mechanical work, that is, to convert the kinetic energy of the wind into electrical energy or mechanical energy. Wind energy is a kind of available energy provided to human beings due to the work done by air flow. It belongs to renewable energy. The kinetic energy of air flow is called wind energy. The higher the air flow velocity, the greater the kinetic energy. The development of wind power generation is imminent, and wind power generation, as a relatively mature rene...
