Problems solved by technology

The disadvantage is that the secondary energy conversion efficiency is low, the adaptability to small wave energy is not strong, and the cost is high
The disadvantage is that the construction of the power station has requirements on the terrain and is not easy to promote
In addition, under small waves, the wave impact received by each section is similar, so no bending moment can be formed, and the output power is geometrically 0, so the economic benefits are limited
[0009] In short, due to various reasons, so far, there has not been a practical wave power generation system

Embodiment Construction

[0075] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0076] The wave energy power generation system is a heave type, including a floating body, a rope, a hydraulic transmission system, a generator, and a base. The input end of the hydraulic transmission system is a plunger cylinder, and the piston rod (13) of the plunger cylinder passes through the rope ( 8), connect the floating body (1), and the plunger cylinder body (14) is connected to the base; the inlet and outlet oil ports (24) of the oil chamber (9) of the plunger cylinder are divided into two paths, and one path passes through the oil outlet check valve ( 31), the high-pressure pipeline (15) is connected to the high-pressure accumulator (33), and the other way is connected to the medium-pressure accumulator (34) through the oil return check valve (32) and the oil return pipeline (16); the plunger The rodless chamb...

Abstract

The invention relates to a wave energy generation system. In the invention, a float body is propelled by wave; a plunger pump piston is pulled by a rope one end of which is tied on the float body and the other end is tied on a plunger cylinder to convert irregular wave push power into hydraulic energy; and a hydraulic system outputs power to a generator for generation. In the wave-falling stage, differential pressure acted at both sides of the piston is adopted to reset the piston and withdraw the rope, thereby reducing the process cost and improving the response speed via multi-cylinder serial connection. The system is adapted to sea wave with various wave shapes, has strong wave-resistant ability and adopts two waterproof anti-corrosion methods with a drawtube type and a sleeve type.

Description

technical field [0001] The invention relates to an ocean wave power generation system. Background technique [0002] Ocean wave energy is an endless renewable energy resource. How to use such abundant energy resources to serve human beings is an important topic that the predecessors and modern people have been studying. Using wave energy to generate electricity is one of the major topics. [0003] The ocean is affected by complex natural factors, and the size and form of its waves and tides change, which makes it difficult for people to use ocean wave energy for stable power generation. [0004] According to past research experience, it is believed that there are several effective methods for using wave energy to generate electricity: oscillating water column wave energy devices, polywave reservoir wave energy devices, pendulum wave energy devices, etc. [0005] The advantages of the oscillating water column wave energy device are that the rotating mechanism does not contac...
