Embodiment Construction

[0024] The specific embodiments of the invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] A movable floating breakwater with an oscillating water column wave energy conversion device is composed of a plurality of floating breakwater modules, and the floating breakwater modules are elastically connected to realize the independence of movement of each module unit and at the same time form a floating breakwater. type breakwater power generation ranch; and the elastic connection between the modules of the floating breakwater can avoid damage caused by the collision between the modules during the wave motion in the external field. Each floating breakwater module described above is an independent structure, which can complete individual power generation and operate independently. A single floating breakwater module includes a square box 1, a power generation device, a connecting device, and an anchoring system. Multiple floati...

Abstract

The invention discloses a movable floating breakwater with an oscillation water column type wave energy conversion device, and belongs to the field of ocean energy utilization. The movable floating breakwater consists of multiple floating breakwater modules; and the modules are elastically connected to realize independent movement and of each module and power generation, and can form a floating breakwater power generation pasture. Single floating breakwater module comprises a square box, a power generation device, a connecting device and a mooring system. The multiple modules are elastically connected through connecting devices. The movement of a floating body is caused by a wave motion to cause movement of a fluid in a power generation cabin, so that the air pressure at the upper part ofthe cabin is continuously changed; the air pressures on the two sides of a turbine are different to form reciprocating air currents; kinetic energy of gas is converted to mechanical energy through anair turbine; and the mechanical energy is converted to electric energy through a generator. The floating breakwater and a wave energy power generation device are fused to realize covering of offshoreocean structures and to generate the electric energy to achieve the advantages of capability of moving and repeating, no limitation from the water depth and the geology and the like; and the movable floating breakwater is simple in structure, easy to produce and maintain, free of pollution to the marine environment and broad in application prospect.

Description

technical field [0001] The invention belongs to the field of ocean energy utilization and relates to a movable floating breakwater with an oscillating water column type wave energy conversion device. Background technique [0002] my country has a vast sea area and a long coastline, and has very rich wave energy resources. The annual average wave power is greater than 3J / m, and the theoretical wave energy reserve is about 70 million KW. In recent years, my country has attached great importance to the research of renewable energy. Among them, wave power generation has become an important part of the research and application of renewable resources in my country, which can provide power resources for islands and offshore platforms far away from the coast with great convenience. Compared with other energy sources, wave power generation has the advantages of being clean and environmentally friendly, having large reserves, being less affected by time and space, and having a relativ...
