Abstract

The invention discloses a tidal current energy generator which comprises a casing (2), end covers (7), an impeller device, guide sleeves (6), magnets (5), winding coils (4) and bearings (3), wherein each end cover (7) and each guide sleeve (6) are connected at each of two ends of the casing (2), the winding coils (4) are connected in the casing (2), the magnets (5) are positioned in the corresponding winding coils (4) and fixedly connected outside the impeller device, the impeller device is rotatably connected with the casing (2) through the bearings (3), each of two ends of the impeller device is hermetically connected with each end cover (7) and each guide sleeve (6), and winding ends of the winding coils (4) are provided with lead wires respectively. On one hand, the tidal current energy generator is simpler in structure, less in component and better in reliability, and on the other hand, part of power needing to be consumed by a speed increaser is omitted, therefore, operating efficiency of the whole generator is improved.

Description

technical field [0001] The invention relates to the technical field of tidal current energy, in particular to a tidal current energy generator. Background technique [0002] my country's ocean energy resources are very rich, and islands and surrounding areas are rich in renewable ocean energy resources, such as tidal current energy and wave energy. Tidal current energy is the kinetic energy formed when the tidal force of the moon and the sun causes the seawater to produce periodic reciprocating horizontal motion, concentrated in the waterways or bays between the shore and islands, and the tidal current energy power generation directly uses the water flow of the ebb and flow to impact the impeller and other mechanical devices to generate electricity. A tidal current energy generator in the prior art includes an impeller device and a generator for converting mechanical energy into electrical energy. Usually, the central shaft of the impeller is connected to the input shaft of...
