Abstract

The invention relates to a water flow vibration generator and belongs to the technical field of vibration power generation. The water flow vibration generator comprises a box body (1), a sealed coil case (5) which is arranged inside the box body and a sealed permanent magnet case (2), wherein a coil group (8) is arranged inside the sealed coil case (5); a permanent magnet group (3) is arranged inside the sealed permanent magnet case (2); one box of the sealed coil case (5) and the sealed permanent magnet case (2) is arranged at the bottom of the box body (1) to serve as a stator in a fixed state, and the other box is connected with the top of the box body of a parallel spring (7) to serve as a vibrator in a suspended state. A movable gap is reserved between the vibrator and the periphery of the box body and the stator; the coil group (8) is opposite to the direction of the permanent magnet group (3); and a water inlet (11) and a water outlet (6) are formed on the box body (1), and arepositioned on the upper parts of two opposite side surfaces of the box body. The water flow vibration generator can generate power by fully utilizing water flow energy in rivers, ditches and shallow seas.

Description

technical field [0001] The invention relates to a water flow vibration generator, which belongs to the technical field of vibration power generation. 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 (Tidal Barrage) technology needs to build a reservoir and use a generator with a water turbine; while the tidal stream (Tidal streams) 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 technologies are not suitable for harvesting energy from currents in rivers, ditche...
