Description
Technical Field
The invention relates to a multifunctional high-stability seaport breakwater, and relates to the technical field of port construction.
Background
The breakwater is an underwater building constructed for blocking the impact force of waves, enclosing a harbor basin and maintaining the water surface stable so as to protect a port from bad weather, so that ships can be safely berthed and operated, and the traditional breakwater has the main function of wave prevention and sand blocking. The breakwater has various types and can be divided into an upright breakwater, a slope breakwater and a special breakwater according to the structural type; the cross-sectional shape can be classified into a slope type, an upright type, a hybrid type, a permeable type, a floating type and the like.
The breakwater is generally built in a sea area with severe sea conditions and large waves, which is a good condition for wave power generation. Ocean energy refers to renewable natural energy sources stored in the ocean, and mainly comprises tidal energy, wave energy, seawater salt difference energy and seawater temperature difference energy. Among them, wave energy appears in the form of mechanical energy, is the highest grade ocean energy, is relatively less limited by time, has the largest energy flux density, and is most widely distributed. According to the survey of the world energy committee, the wave energy available in the world reaches 20 hundred million kW, which is equivalent to 2 times of the current world generation energy. Therefore, wave energy is considered to be important in all oceans in the world.
The wave energy power generation is based on the principle that the device works through the motion of waves and drives a waterproof generator to generate power, and mechanical energy of water in the form of kinetic energy and potential energy is converted into electric energy. Generally, wave energy is converted into electric energy through three-stage conversion, wherein the first-stage conversion is that a wave receiver absorbs wave energy; the second stage conversion optimizes the first stage conversion by the intermediate conversion device to generate stable energy; the third stage of conversion converts the stabilized energy into electrical energy by a power generation device.
The existing breakwater has single function and cannot generate electricity by utilizing the impact force of waves on the breakwater.
