Abstract

The invention discloses a blade assembly for tidal current energy power generation and a tidal current energy water turbine. A blade assembly for tidal current energy generation, comprising: a blade and a plurality of suppressors, the plurality of suppressors are distributed along the length direction of the blade, the suppressor includes a bottom plate and two side plates, and a plurality of suppressors are formed on the bottom plate groove, the side plates are arranged on the corresponding side of the bottom plate, and the two side plates are arranged obliquely; an inflow area is formed between one ends of the two side plates, and the two side plates An outflow area is formed between the other ends, the width of the inflow area is smaller than the width of the outflow area, and the bottom plate is arranged on the surface of the blade. To optimize the hydrodynamic performance of the blades to improve the power generation efficiency of tidal energy turbines.

Description

technical field [0001] The invention relates to the technical field of tidal current power generation, in particular to a blade assembly for tidal current power generation and a tidal current water turbine. Background technique [0002] As a clean and renewable energy source, ocean tidal current energy has the characteristics of high energy density, abundant resources, and low impact on the environment. In recent years, governments and research institutions around the world have increased their research investment and financial support for tidal current power generation technology, and have developed various types and specifications of tidal current power generation devices. Tidal current power generation technology has been recognized worldwide. rapid development. The tidal current energy turbine power generation device converts the kinetic energy of water into the mechanical energy of the blades of the turbine, and finally converts it into electrical energy through the co...
