Abstract

The invention discloses a mechanical-electrical-hydraulic integrated full-sealed wave energy power generating device. A first floating body and a second floating body are fixedly arranged at the two ends of a sealed flow tube, so that the first floating body and the second floating body support the whole wave energy power generating device to float on the sea; an energy extracting unit, a stream guiding mechanism and a fluid medium are arranged in the sealed flow tube, the device swings in a reciprocating manner under the action of waves, and the fluid medium flows in the sealed flow tube in a reciprocating manner through the energy extracting unit, so that the fluid medium absorbs wave energy and transfers the wave energy to the energy extracting unit for generating power; and an electric generator in the energy extracting unit rotates in one direction all the time by means of the flow guiding mechanism to complete the wave energy power generating process. According to the mechanical-electrical-hydraulic integrated full-sealed wave energy power generating device, fluid, machine and electric power integrated design is adopted, the interior is completely isolated from sea water, the structure is simple, few moving parts exist, and moveless sealing is achieved; by means of internal and external shape design, mass distribution design and culvert tube flow channel design, reliable, efficient and stable wave power generation can be achieved.

Description

technical field [0001] The invention belongs to the field of wave energy power generation, and in particular relates to an electromechanical-hydraulic integrated fully sealed wave energy power generation device. Background technique [0002] Under the dual pressure of the energy crisis and environmental problems, the development and utilization of new energy sources has received widespread attention. The amount of wave energy resources is large and the application prospects are broad. However, the existing wave energy power generation technology has technical bottlenecks of low reliability and low efficiency, and a breakthrough in the principle of power generation devices is awaited. [0003] Wave energy power generation refers to the use of energy generated by the vertical movement, horizontal movement of sea waves and the pressure change of water in the waves. Wave energy is usually converted into reciprocating mechanical energy through wave energy generation devices, and ...
