Description

Technical field [0001] The invention relates to a fluid kinetic energy conversion device, in particular to a vortex-induced vibration wind power generation device based on the principle of resonant cavity acoustic amplification. Background technique [0002] With the rapid development of science and technology, the wireless sensor network technology produced by the combination of computer network technology and wireless sensor technology has made great progress. It can detect and collect information about objects detected in the surrounding environment in real time, and pass this information through wireless The method is sent to the user terminal to achieve target detection within the specified range. In order to detect the information of the entire environment as much as possible and improve the accuracy of the information, wireless sensor network nodes are usually distributed in a large number and high density, so the required energy is often provided by chemical batteries.

Problems solved by technology

[0003] At present, electromagnetic generators are widely used in areas rich in wind resources, but because they include rotating mechanisms such as turbines, gearboxes, and generators, they have large volumes, large energy losses, and high cost and maintenance costs.

Solar power generation equipment is widely used due to its advantages of safety and reliability, no risk of depletion, and no need to erect transmission lines. However, the distribution density of irradiated energy is small, it is greatly affected by the environment, the laying area is large, and the cost of power generation is high.
