Floating breakwater with wave power generation function and fishery breeding function

Abstract

The invention discloses a floating breakwater with a wave power generation function and a fishery breeding function. The floating breakwater comprises a wave absorbing structure, power generation devices and a fishery breeding device, wherein the wave absorbing structure comprises a breakwater body, a plurality of moon pools are arranged on the breakwater body, a plurality of transverse supports are arranged at the top of each moon pool, the power generation devices are fixed on the transverse supports, and the fishery breeding device is arranged at the lower part of the breakwater body. According to the floating breakwater with the wave power generation function and the fishery breeding function, by adopting the cuboid breakwater body containing the moon pools, materials can be effectively saved, and the construction cost is reduced; by arranging the vertical motion type power generation devices, wave energy can be converted into electric energy; by arranging the fishery breeding device, the application function of the breakwater can be broadened, the economical efficiency of the breakwater is improved, the wave propagation track can be disturbed, and wave energy can be dissipated; by the adoption of stand columns with spiral rising type wing plates, vortex-induced motion can be effectively avoided; and by arranging a heaving plate, the movement of the breakwater can be reduced to achieve the optimal wave absorbing effect.

Description

technical field [0001] The invention relates to a floating breakwater with the functions of wave power generation and fishery cultivation, and belongs to the technical fields of wave power generation, fishery cultivation and wave prevention and wave elimination engineering. Background technique [0002] In recent years, due to the rise of ocean development, a large number of floating structures have been used in vast waters. In order to prevent marine structures from being damaged by waves, floating breakwaters have been widely used. Floating breakwater has the following advantages: 1. It can be used in a wide range of water areas; 2. The construction cost is low and not affected by the water depth; 3. It allows the flow of water and the migration of marine organisms such as fish; 4. It is simple to construct and easy to maintain. [0003] However, the existing floating breakwaters still have the following three main disadvantages: [0004] 1. The design of the existing flo...

Problems solved by technology

[0004] 1. The design of the existing floating breakwater mainly focuses on the improvement of the wave absorption performance of the breakwater, ignoring the development and utilization of other functions of the breakwater, resulting in a single function of the existing floating breakwater

[0005] 2. Most of the existing floating breakwaters mainly rely on the way of reflecting incident waves to achieve the purpose of reducing waves, ignoring the application of other methods such as disturbing wave propagation trajectory and dissipating wave energy, which leads to the short-period wave impact of existing floating breakwaters. The wave-absorbing effect is better, but the wave-absorbing effect is not ideal for long-period waves

[0006] 3. According to the research and experiments of wave theory, 98% of the total wave energy is concentrated in the water depth range from the surface layer of the water body to three times the wave height below the water surface. Shallow, can only block waves and currents within a certain depth below the water surface
