The wave energy is a specific form of ocean energy and is one of the most main energy sources in the ocean energy, and the energy contained in the wave mainly refers to the kinetic energy and potential energy of the ocean surface wave. The wave energy resources in China are considerable, the content of wave energy in offshore sea areas reaches about 1.5 hundred million kW, and the exploitable and utilizable amount is about 2300 to 3500 thousand kW; the tidal current energy is a clean, pollution-free and renewable new energy with abundant reserves, the global tidal current energy reserve is about 50 hundred million kW, and the total amount of the developed and utilized tidal current energy reaches 3 hundred million kW. With the continuous exhaustion of fossil energy and the continuous improvement of environmental protection requirements, the development and utilization of ocean energy resources are more and more emphasized in various countries in the world, and the technology of generating electricity by using wave energy or tidal current energy by using various energy-obtaining devices is continuously broken through.
The current China is increasingly accelerating in the development of south China sea island reefs, and the problem of power supply of infrastructure on the island reefs in the open sea needs to be solved urgently. The method comprises the following steps that (1) coral reef coasts are distributed around island reefs in south China sea, a typical coral reef coast consists of a steep reef front slope connected with a deep sea seabed and a relatively horizontal reef plateau extending to a shore beach, waves in sea are transmitted to the shore reefs from deep sea, and due to the fact that the terrain is steep and the water depth on the reef plateau is shallow, the water depth is reduced sharply, and the waves are broken near the reef edge; as the water depth becomes shallow, the tidal current flow velocity near the reef edge is increased. Therefore, due to the steep change of the terrain, abundant wave energy and tidal current energy are stored near the reef edge of the coral reef.
At present, power generation is mainly performed at home and abroad by using potential energy of wave energy or kinetic energy of tidal current energy, for example, a water turbine system for generating power by using ocean energy disclosed in the chinese patent application No. 201511016787.1 adopts a wave-crossing power generation mode, most of the water turbine system generates power by converting kinetic energy of wave energy into potential energy, the energy conversion rate is low, and most of the prior art is to improve the water turbine system suitable for seawater power generation to improve the energy conversion efficiency, and no innovation can be conveniently provided for realizing comprehensive utilization of ocean energy. Most of the traditional ocean power generation devices are floated or semi-submerged on the deep sea surface of the sea and are difficult to adapt to the steep terrain of the coast of the coral reef. In addition, on the coral reef coast, the direction of waves is mostly perpendicular to the coast, but certain angular deviation still exists along with changes of wind direction, tidal ocean current and the like, the existing over-wave generator is mostly fixed, and when the direction of wave impact changes, the power generation efficiency of the over-wave generator is further greatly reduced.
