Coast protection submerged dike capable of utilizing wave energy

Abstract

The invention belongs to the field of offshore engineering, and discloses a coast protection submerged dike capable of utilizing wave energy. The coast protection submerged dike comprises a submergeddike main body and a hydroelectric generating set, wherein the submerged dike main body is fixedly installed on an offshore seabed surface, multiple rows of guide blades arranged in the wave propagation direction are arranged at the top of the submerged dike main body, a flow guide pipeline is arranged in the position, below each row of guide blades, of the submerged dike main body, and an outletis formed in the end, close to the coast, of each flow guide pipeline; each guide blade is provided with an opening facing the wave facing side or the wave backing side, the openings communicate withthe flow guide pipelines, the openings of the guide blades arranged in the same row face the same direction, and the openings of the guide blades arranged in two adjacent rows face opposite directions; and the hydroelectric generating set comprises low-water-head turbines and generators, wherein the low-water-head turbines are installed at the tail ends of the flow guide pipelines in the water flow direction, the generators are fixed in the submerged dike main body, and the low-water-head turbines are used for driving the generators to output electric energy. According to the coast protectionsubmerged dike, wave energy can be converted into electric energy, economic benefits are achieved, wave blocking and wave absorbing can be achieved, and life and property of people are guaranteed.

Description

technical field [0001] The invention relates to the field of offshore engineering, in particular to a coast protection submerged dike that can utilize wave energy. Background technique [0002] As the world's industrialization continues to advance, people's demand for energy is gradually increasing. The contradiction between the severe climate situation, the rapid depletion of non-renewable energy sources and the growing energy demand drives human beings to look for new renewable energy sources, thus fundamentally achieve sustainable development. Ocean wave energy, as a clean and renewable energy, is rich in reserves and is increasingly attracting people's attention, and can provide a solid backing for future social and economic development. [0003] For a long time, the erosion and destruction of coastal natural disasters such as storm surges and tsunamis have brought immeasurable harm to people's social economy, life and property. A submerged embankment is a dike whose c...
