Elastic film box type wave power generation device

Abstract

The invention belongs to the technical field of ocean energy utilization and renewable energy power generation, and particularly relates to an elastic film box type wave energy conversion device. Theelastic film box type wave energy conversion device is used for wave power generation in shallow water and offshore areas. The elastic film box type wave energy conversion device mainly and structurally comprises elastic films, box bodies, box body walls, water outlet one-way valves, water inlet one-way valves, a water outlet pipeline, a water inlet pipeline and power generation equipment; the twoelastic films are arranged on the wave facing surfaces and the wave backing surfaces of the two box bodies in a covered mode correspondingly, and the two box bodies are arranged on a device base fixed on the seabed in parallel; two water holes are formed in the side wall face of each box body, one water inlet one-way valve and one water outlet one-way valve are arranged on each water hole, and water inlet holes and water outlet holes of the two box bodies communicate and are connected with an internal hydraulic assembly of the power generation equipment correspondingly. According to the device, wave energy is converted into pressure energy of water in the box bodies through the effect of differential water pressure under the wave surface on the elastic films, and then the pressure energyof the water is converted into electric energy through the hydraulic assembly and a generator in the power generation equipment.

Description

technical field [0001] The invention belongs to the technical field of marine energy utilization and renewable energy power generation, and in particular relates to an elastic film box-type wave energy power generation device. Background technique [0002] Wave energy is a promising clean and renewable energy, which has the advantages of good energy quality, large storage capacity, and wide distribution. Its development and utilization are of great significance for promoting sustainable development and marine resource development. The development and utilization of wave energy has been included in the national energy development strategy and has broad development prospects. [0003] The existing offshore wave energy utilization technology can be divided into two types: point absorption type and line absorption type. PTO (Power Take-off, energy extraction) damping converts the mechanical energy of floating body movement into hydraulic energy or electromagnetic energy, and th...
