Abstract

The invention discloses an impact type vibration generator belonging to the technical field of vibration generation. The impact type vibration generator comprises a generator frame (1), two permanent magnets and a coil box (8), wherein the two permanent magnets are respectively fixed on the top surface and the bottom of the generator frame; the coil box (8) is positioned between the two permanent magnets, a second side wall opposite to a first side wall (18) of the generator frame is provided with an opening, one end of the coil box (8) is connected with the first side wall (18) by a first level spring (7), and the other end of the coil box (8) extends out of the generator frame through the opening and is connected with an excitation vibration plate (11). The impact type vibration generator has the other deformation structure that the first level spring (7) is replaced by a second level spring (4), one end of the second level spring (4) is fixed on the excitation vibration plate, and the other end of the second level spring is fixed on a second side wall (16) of a box body. The descriptive impact type vibration generator is of a flat shape, does not have rotating members, not only can use ocean current in the ocean, but also can use shallow water current in rivers and ditches to generate electricity and can reduce the adverse effect of the generator for the environment and maintenance cost at the same time.

Description

technical field [0001] The invention relates to an impact type vibration generator and a power generation method thereof, and relates to a device and a power generation method for generating power by utilizing water flow and its velocity fluctuation. Background technique [0002] In existing hydroelectric power generation technology, it is necessary to build a reservoir and use a generator with a water turbine. Among the existing tidal power generation technologies, the tidal dam technology also needs to build a reservoir and use a generator with a water turbine; while the tidal stream technology uses an underwater generator with a water turbine. In wave power generation technology, it is necessary to build a reservoir (TAPCHAN gradient channel wave capacity conversion method) or a closed cavity (OWC oscillating air column method) and use a generator with a water turbine or a steam turbine. Due to the need to build water storage units and use rotating parts, these technolog...
