Flexible blade type vertical shaft tide energy water turbine

Abstract

A flexible blade type vertical shaft tide energy water turbine comprises a first power generator, a first machine frame, a first upper support, first blades, a first blade shaft, a first lower support, a first lower shaft sleeve, a second flow inlet, a second machine case, a second upper support, a second upper shaft sleeve, a second power generator, a second coupling, a second machine frame, a second roller, second blades, a second piston type one-way valve, a second flow-out pipe, a second flow outlet, a second lower support, a second lower shaft sleeve, second flange bearings, a second connecting piece, a second blade shaft, a first piston type one-way valve, a first flow-out pipe, a first flow outlet, first flange bearings, a first connecting piece, a first roller, a first flow inlet, a first upper shaft sleeve, a first machine case and a first coupling. The first flow inlet is formed in the left side of the first machine case. The first flange bearings are installed at the upper end and the lower end inside the first machine case respectively. The flexible blade type vertical shaft tide energy water turbine has the advantages that the multiple blades are arranged on the blade shafts, and water which flows out of the flow out pipes of the water turbine can be reused.

Description

technical field [0001] The invention relates to a flexible blade type vertical axis tidal current energy turbine, which belongs to the technical field of ship equipment. Background technique [0002] A water turbine is a power machine that converts the energy of water flow into rotational mechanical energy. It belongs to the turbine machinery in fluid machinery. There is only one blade on the impeller shaft of a conventional vertical axis tidal energy turbine, but in actual situations, the ocean current is not in one The flow in the two-dimensional plane is a three-dimensional flow, and the individual blades cannot maximize the conversion efficiency of the water flow energy; and the water flowing out of the outflow pipe in the turbine is not used for secondary use. In order to solve the above difficulties, it is necessary to develop a vertical-axis tidal energy turbine with multiple blades on the blade shaft, and the water flowing out of the outflow pipe in the turbine can b...
