Double-feed type wind power generation equipment

Abstract

The invention relates to the technical field of wind power generation, and discloses double-feed type wind power generation equipment. A tower frame and a foundation are included. A base is arranged between the tower frame and the foundation. The bottom of the tower frame is welded to the top of the base. Grooves are formed in the outer side of the base and internally fixedly connected with limiting plates. The interior of each limiting plate is movably in cup joint with a rivet, wherein one end of the rivet penetrates through the limiting plate and the base and extends to the bottom of the base to be fixedly connected with the foundation, and the outer side of the rivet is provided with a compression spring. According to the double-feed type wind power generation equipment, through the arrangement of the compression springs, when the rivets and the limiting plates are connected, certain buffering force is provided, and connectivity between the rivets and the foundation is improved; and meanwhile, a stable work environment is provided for normal work of wind power generation equipment, accordingly, the power generation efficiency of the wind power generation equipment is improved,the installing cost is saved, and development and popularization of the wind power generation equipment are facilitated.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a double-fed wind power generation device. Background technique [0002] Wind power generation is the conversion of wind kinetic energy into electrical energy. As a clean and renewable energy, wind energy has attracted more and more attention from countries all over the world. Wind energy is 2×10^7MW, which is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. The kinetic energy of the wind is converted into mechanical kinetic energy, and then the mechanical energy is converted into electrical kinetic energy. This is wind power generation, wind power generation The principle is to use the wind to drive the blades of the windmill to rotate to promote the generator to generate electricity. [0003] With the continuous development of industry, the consumption of electric energy in all walks of life is increasing year...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a doubly-fed wind power generation equipment, which has the advantages of high installation stability, convenient maintenance and maintenance, and easy replacement of rotating blades, and solves the problems of poor installation stability and poor installation stability of the existing wind power generation equipment during wind power generation. It is inconvenient for operators to carry out inspection and maintenance in the later stage, and it is not conducive to replacement when the rotor blade is damaged, which affects the normal operation of wind power generation equipment
