Oscillating piston type wave power generation method and system

Abstract

The invention relates to an oscillating piston type wave power generation method and a system. When waves is upheaved and a floating body rises, a rolling cylinder is locked, and enlarging of the distance between the floating body and an anchor base is utilized for pulling a hydraulic cylinder. When the hydraulic cylinder is pulled, high-pressure hydraulic oil is output for driving a hydraulic motor so as to drive a generator to generate electricity. When a working stroke of the hydraulic cylinder is finished, a signal is transmitted to the rolling cylinder to lay a rope down, and the hydraulic cylinder is rapidly reset under the action of restoring force. When resetting is finished, a signal is sent to the rolling cylinder to stop laying the rope down. As the distance between the floating body and the anchor base is continuously enlarged, the hydraulic cylinder is pulled again for doing work, and circulation is performed in such mode. When the waves and floating body fall down, the hydraulic cylinder is reset, and the rope is taken back by the rolling cylinder. The system is capable of automatically adapting to waves in most wave shapes, storm-resistant capacity is strong, and the most importance thing is in the process of wave rising, the hydraulic cylinder can automatically reset and do work repeatedly.

Description

technical field [0001] The invention relates to a wave power generation method and 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. For more than 100 years, scientists from all over the world have put forward more than 300 kinds of ideas and invented various wave energy power generation devices. In principle, there are oscillating water column, pendulum plate type, oscillating float, floating body angle type, shrinking channel type, etc., according to According to different foundation platforms, it can be divided int...

Problems solved by technology

[0006] There is also a wave power generation system, that is, the floating body heaving hydraulic cylinder method, but because the wave height is often different in size, up to more than ten meters, if the hydraulic cylinder is made very long, the cost is too high and the waste is serious, and the production is very short , leading to far insufficient travel
