Integrated system of ocean tidal current energy power generation device and buoyant raft type aquaculture structure

Abstract

The invention provides an integrated system of an ocean tidal current energy power generation device and a buoyant raft type aquaculture structure, and belongs to the technical field of ocean engineering and aquaculture engineering. A turbine generator is connected with a buoyant raft through a lifting rod, the turbine generator is in rigid connection with the lifting rod, the lifting rod is connected with a cross beam of the buoyant raft through a bolt, the buoyant raft is fixed to an anchorage of the seabed through an anchor rope and an anchor chain, a hanging lifting rope is arranged on the buoyant raft, and shellfish is attached to the lifting rope; the tidal energy turbine generator is connected with a deep sea floating buoyant raft type aquaculture device, electric energy generated by the turbine generator can provide power for the deep sea floating buoyant raft type aquaculture device, due to existence of the floating buoyant raft type aquaculture device, a flow increasing area exists on the bottom of the raft type aquaculture structure, the flow speed of the flow increasing area is obviously larger than the surrounding environment flow speed, the power generation efficiency of the turbine generator can be greatly improved, economy of the integrated system is improved, and the device has the beneficial effects of being simple in structure, convenient to manufacture and capable of having the higher practical value.

Description

technical field [0001] The invention belongs to the technical field of ocean engineering and aquaculture engineering, and in particular relates to an integrated system combining ocean tidal current energy generators and floating raft farming facilities. Background technique [0002] More than 70% of the earth's surface is covered by oceans, which provide human beings with abundant renewable energy. Marine renewable energy mainly exists in the form of thermal energy, kinetic energy (waves and currents), chemical energy and biomass energy. Humans extract renewable energy from the ocean in various ways, mainly divided into: wave energy, tidal current energy, ocean temperature difference energy, and salinity difference energy. The kinetic energy contained in ocean currents can be converted into electrical energy through sophisticated turbine generator technology. Due to economic feasibility, only part of ocean energy has been developed at present. Although only part of ocean e...

Problems solved by technology

[0003] In recent years, with the promotion of intelligent aquaculture, deep-sea aquaculture has an increasing demand for electric energy. The electric energy required by traditional aquaculture systems cannot be effectively supplied. In deep-water sea areas, traditional electric energy is used to supply aquaculture systems. Expensive
