Abstract

The invention discloses a low-cost and high-reliability airtight floating-type wave energy storage device. The low-cost and high-reliability airtight floating-type wave energy storage device comprises an airtight floater, a balance weight, a steel cable and an anchor chain, wherein the balance weight is arranged below the floater; the upper end of the balance weight is connected with the interior of the floater through the steel cable; the lower end of the balance weight is connected with the anchor chain; the inner cavity of the floater comprises an equipment cavity and an energy storage cavity which are hermetically isolated from each other from top to bottom; a gas bag gas-pumping device is installed at the middle position of the equipment cavity; a cable guide tube is vertically installed below a position facing the centre of the gas bag gas-pumping device, of the energy storage cavity, so that the steel cable penetrates through the energy storage cavity and then is connected with the central position of the lower part of a movable end of the gas bag gas-pumping device; and the upper part of the movable end is connected with the top of the equipment cavity. The invention further discloses a low-cost and high-reliability airtight floating-type wave power generation device. The low-cost and high-reliability airtight floating-type wave energy storage device and the low-cost and high-reliability airtight floating-type wave power generation device, which are disclosed by the invention, have the advantages of being simple in structure, reliable in working, low in cost, easy to maintain, not liable to damage, high in adaptability, simple in field delivery and recovery, and the like.

Description

technical field [0001] The invention relates to a marine wave energy power generation device, in particular to a low-cost, high-reliability airtight floating wave energy storage device and a power generation 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 invent...
