Abstract

The invention provides a power generating device which comprises a main vibration assembly, a supporting assembly and a piezoelectric plate. The main vibration assembly is used for generating vortex-induced vibration in a constant laminar flow; the supporting assembly is connected to the main vibration assembly and is used for supporting the main vibration assembly and generating vibration under avortex-induced vibration effect of the main vibration assembly; and the piezoelectric plate is arranged on the supporting assembly and is used for generating deflection deformation under a vibrationeffect of the supporting assembly so as to form a potential difference. In the power generating device, the main vibration assembly is not provided with a blade structure, and the corresponding supporting assembly does not need a big height requirement, so that the transportation difficulty is reduced; and when a typhoon happens or wind power is large, the power generating device is not easy to damage, and the risk of damage due to strong wind is reduced.

Description

technical field [0001] The invention belongs to the technical field of power generation, and more specifically relates to a power generation device. Background technique [0002] In the traditional technology, the method of obtaining electric energy by burning fossil energy has the disadvantages of serious environmental pollution and non-renewability, and seriously threatens the sustainable development of human society. Therefore, seeking clean and renewable alternative energy has become a Very serious problem. [0003] And existing wind power generator is because of its tower body is higher, and blade is longer, under the situation of strong wind, may cause the serious damage such as collapse tower, blade breaks, unit catches fire, even runaway. Every year, 7.2 typhoons from the western Pacific land in China, which will cause very huge losses. For example, the typhoon "Sangmei" in 2006 caused a loss of nearly 70 million yuan to Cangnan Hedingshan Power Plant. At the same ...
