Self-floating tidal current power generation device

Abstract

The invention relates to the technical field of power generation, and discloses a tide energy power generation device capable of sinking or floating automatically. The tide energy power generation device comprises a mooring rope (3). One end of the mooring rope (3) is fixed to the seafloor, and the other end of the mooring rope (3) is connected with a special-shaped flow guide cover (1). The special-shaped flow guide cover (1) is provided with a tide inlet (7) and a tide outlet (8). A tied water turbine (2) is arranged at the tide outlet (8) of the special-shaped flow guide cover (1). A cable (4) is connected to the tied water turbine (2) and fixed to the seafloor together with the mooring rope (3). A balancing wing (5) is arranged at the rear end of the tide outlet of the special-shaped flow guide cover (1). The bottom of the special-shaped flow guide cover (1) is connected with a base (6) in a rotating mode. The tide energy power generation device can float or sink automatically according to the flow rate of a tide without being driven by a power device. The dual effects of gathering energy of beam current and providing ascending power can be achieved through the special-shaped flow guide cover. Due to the fact that the mooring rope is fixed to the seafloor, the cost of the fixing method is lower than that of the pile foundation structure fixing method.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to an automatic sinking and floating tidal current energy generating device. Background technique [0002] my country's coastline is more than 18,000 kilometers long, and there are violent tides and current movements in many coastal areas, which provide my country with broad prospects for tidal energy development. [0003] Tidal energy (tidal current energy) is to arrange open hydroelectric power generation devices in strong tidal sea areas, and use the horizontal flow of seawater to generate electricity. [0004] The installation forms of tidal energy devices can be divided into three types: ① Arranged on the seabed in the form of a base, ② Suspended in the water body by relying on engineering facilities, ③ Floating on the water surface by relying on floating bodies. The disadvantage of the base unit is that the seabed flow rate is small, so the energy of the maximum flow...

AI Technical Summary

Problems solved by technology

[0006] The present invention aims at the disadvantages of the base unit, the floating unit and the suspension unit in the prior art that the construction cost is high, they are greatly affected by the waves, and the stability is not high, and provide a device that can automatically float and sink according to the flow rate of the tidal current, and has a low construction cost. , and does not affect the high-efficiency tidal current energy generation device for the navigation of passing ships
