Embodiment Construction

[0011] The position of a connecting shaft 3 of the biomimetic water turbine generator 1 is respectively mechanically fixed with blades 2 . The motor 1 is a currently available commercially available device that converts water power into electricity. The motor 1 is equipped with a connecting shaft 3, and the other end of the connecting shaft 3 is equipped with a blade 2, and the blade 2 is a long arc-shaped plate body. The role of the blade 2 is to receive the hydrodynamic rotation to drive the generator. It is fixed on the coupling shaft 3, the two surfaces of the blade 2 are in the shape of a grid 4 imitating a bird's wing feather or shark skin, and the grid 4 is a tongue-shaped or triangular body dug out on the surface of an arc-shaped plate The pit-shaped body, the front and back of the pit-shaped body facing the direction of water flow is a backward concave arc surface, the left and right sides are vertical surfaces, and each grid 4 is separated by a rib plate 5, and the ...

Abstract

The invention relates to a bionic water turbine which comprises a generator, blades, a connecting shaft, grids and reinforcing plates. The blades are fixed on the connecting shaft of the generator by a mechanical method, both sides of each blade are in a grid shape resembling the wing feather of a flying bird or the skin of a shark, and each grid is a tongue-shaped or triangular pit dug on a circular arc surface so as to be an independent hydraulic driving unit. The upstream face of each blade in operation can be driven by the vertical force of water, and water at the back of the blade flows along the blade surface and can form eddy resistance which partially becomes pushing force and centripetal force; water friction on both sides of the each blade decreases the friction resistance, increases the water flowing speed, increases the amount of water flowing in unit time and improves the hydraulic driving efficiency so as to generate more power under the same hydraulic condition and have good operation stability.

Description

technical field [0001] The invention provides a bionic water turbine Background technique [0002] Hydroelectric power generation is realized by hydraulic impact on the blades of the water turbine. During operation, the water flow impacts the blades at a certain angle to drive the generator to run and generate electricity. The disadvantages of low efficiency and large slippage loss. Contents of the invention [0003] The purpose of the present invention is to provide a bionic water turbine. [0004] The present invention is realized in the following way [0005] The bionic water turbine is a new technology proposed to improve the existing water turbine blades. The biomimetic water turbine is composed of a generator 1, a blade 2, a connecting shaft 3, a grid 4, and ribs 5. The blades of the biomimetic water turbine imitate the surface structure of the feathers of the wings of birds or the skin of sharks. After tens of millions of years of evolution, the wings of birds h...
