Tide energy power generation device capable of sinking or floating automatically

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 ups and downs tidal current energy generation device. Background technique [0002] my country's coastline is more than 18,000 kilometers long, and there are violent tidal and tidal movements in many coastal areas, providing my country with a broad prospect of tidal energy development. [0003] Tide energy (tidal energy) is to arrange open hydroelectric power generation devices in strong tide sea areas, and use the flow of seawater in the horizontal direction to generate electricity. [0004] The installation forms of tidal energy devices can be divided into three types: ① they are arranged on the seabed in the form of bases, ② they are suspended in the water body by means of engineering facilities, and ③ they float on the water surface by means of floating bodies. The disadvantage of the base unit is that the subsea flow rate is small, so the energy of the...

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
