Sealed pneumatic wave energy storage device and power generation device

Abstract

The invention discloses a sealed pneumatic wave energy storage device. The sealed pneumatic wave energy storage device comprises a sealed floater, an anchor chain and an anchor, wherein an inner cavity of the floater comprises an energy storage cavity and an equipment cavity which are sealed and isolated from each other from top to bottom; a main spring, an auxiliary spring, a heavy object and air pumping devices are mounted in the equipment cavity; the heavy object is suspended in the central position of the equipment cavity through the main spring; a plurality of air pumping devices are uniformly articulated between the heavy object and the inner wall of the equipment cavity by taking a vertical central axis of the equipment cavity as a symmetric axis; the air pumping devices are driven by up-and-down vibration motion, left-and-right vibration motion and front-and-back vibration motion of the heavy object under wave disturbance, so that compressed air is continuously pumped into the energy storage cavity and is stored. The invention also discloses a sealed pneumatic wave energy power generation device. The sealed pneumatic wave energy storage device has the advantages that the structure is simple, the motion components are not in contact with seawater, the corrosion resistance is high, the device is conveniently mount and put on the site, and the device can be adapted to any wave direction, tide level, terrain and sea condition.

Description

technical field [0001] The invention relates to a marine wave energy generating device, in particular to an airtight pneumatic wave energy storage device and a generating device, belonging to the technical field of new renewable energy. Background technique [0002] With the development of the world economy, the surge of population, and the progress of society, the human demand for energy is increasing day by day. In order to solve problems such as the increasing shortage of energy and the increasingly severe environment, all countries are scrambling to develop renewable energy. The collection, conversion and application of ocean wave energy, such as power generation, is a new field that has just started. Its technology is not perfect enough, and it lacks effective devices that can be put into practical use for a long time. Poor adaptability, vulnerable to storm damage, low conversion efficiency and other issues. Contents of the invention [0003] In view of the above-me...

AI Technical Summary

Problems solved by technology

[0004] The problem to be solved by the present invention is that the core components of most existing wave power generation devices are directly immersed in seawater, it is difficult to overcome the corrosion of seawater and the attack of storms, and the adaptability to conditions such as tide level, terrain and sea conditions is poor
