Closed three-dimensional pull rope type wave energy storage device and power generation device

Abstract

The invention discloses a closed three-dimensional pull rope type wave energy storage device. The closed three-dimensional pull rope type wave energy storage device comprises a closed floater and at least two heavy balls, wherein anchor chains are respectively connected to the lower ends of the heavy balls, wire ropes are respectively connected to the upper ends of the heavy balls, an equipment cavity and an energy storage cavity which are isolated each other in a sealing mode are formed in an inner cavity of the floater from top to bottom, at least two groups of oscillation rocker pumping devices are installed in the equipment cavity in an axisymmetric mode by using the vertical center axis of the equipment cavity as a symmetric axis, rope guide tubes which are uniformly distributed along a circumferential direction and correspond to each group of the oscillation rocker pumping device penetrate through the energy storage cavity, the upper ends of the wire ropes respectively penetrate through the rope guide tubes and are connected with the corresponding oscillation rocker pumping devices, and the oscillation rocker pumping devices are driven to continuously pump compressed air into the energy storage cavity so as to be stored by the tensile strength change of the wire ropes. The invention further discloses a closed three-dimensional pull rope type wave power generation device. The closed three-dimensional pull rope type wave energy storage device and the closed three-dimensional pull rope type wave power generation device have the advantages of simple structure, reliability in transmission, high corrosion resistant capability, simplicity in maintenance, good adaptability and the like, and movable joints are not soaked in seawater.

Description

technical field [0001] The invention relates to a marine wave energy generating device, in particular to a closed three-dimensional rope-drawn 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...
