Description

technical field [0001] The invention relates to a power generating device, in particular to a wind power generating device based on the positive piezoelectric effect. Background technique [0002] Wind energy has the advantages of being clean, cheap, renewable, and has large reserves. Utilizing wind energy for power generation has great application value and good development prospects. At present, the main way of wind power generation is to use wind turbines to generate electricity. The wind turbines are mainly composed of impellers, speed increasers, generators, etc., and their power generation can reach hundreds of kilowatts, and their power generation capacity is very strong. However, the wind turbine has a large and complex structure, difficult installation and maintenance, and high cost. The unit contains moving parts such as gears, bearings, and transmission shafts. The requirements for these moving parts are very high, and maintenance and repair are inconvenient. [...
