Reciprocating type wind power generation system

Abstract

The invention discloses a reciprocating type wind power generation system. The reciprocating type wind power generation system comprises a wind collector, a blade system, a transmission system and a generator assembly. The wind collector collects wind energy in all directions, and transmits the wind energy to the blade system, blades of the blade system reciprocate to convert the wind energy into mechanical energy, and the blade system is connected with the generator assembly through the transmission system. The transmission system converts reciprocation movement of the blades into linear movement, the blades can reciprocate to the output end in a continuous rotation mode, and a speed increasing function of the blades is achieved. The generator assembly converts the mechanical energy into electric energy, and therefore conversion from the wind energy to the electric energy is achieved. The reciprocating type wind power generation system has the advantages of being convenient to manufacture, install and maintain, free of influences of the wind directions, capable of generating power through breezes, high in wind energy utilization rate and the like.

Description

technical field [0001] The invention relates to a reciprocating wind power generation system. Background technique [0002] With the shortage of energy and the deterioration of the ecological environment, countries around the world have generally realized the importance of new energy power generation technology, and have carried out a lot of research and development work in the fields of wind energy, nuclear energy, and solar energy. As a clean and renewable energy, wind energy has been strongly encouraged by governments of various countries and has developed rapidly. In the past 10 years, the installed capacity of wind power in the world has grown rapidly at an annual growth rate of nearly 30%, and the installed capacity of wind power in my country has grown the fastest. The country with the largest wind power installed capacity in the world. [0003] At present, the horizontal axis wind turbine is the main structural form of wind energy utilization, but the entire wind tur...

AI Technical Summary

Problems solved by technology

[0003] At present, the horizontal axis wind turbine is the main structural form of wind energy utilization, but the entire wind turbine power generation system must be installed on a tower above the ground, resulting in high cost and difficulty in manufacturing, installation and maintenance. During the operation of the wind turbine , the entire wind turbine power generation system also needs to yaw against the wind according to the wind direction, which increases the complexity of the system and reduces the utilization rate of wind energy

In recent years, vertical axis wind turbines have also been developed and applied to a certain extent. Although the transmission system of vertical axis wind turbines can be installed on the ground, the blades still need to be installed on the tower, which increases the difficulty of system maintenance. The angle of attack of the vertical axis blade is fixed, which limits its application in low wind speed
