Tidal power generation device

Abstract

The invention relates to a tidal power generation device, which comprises a fixed base, a generator, an output shaft, a forward rotating shaft, a reverse rotating shaft, a gear set and impellers, wherein the fixed base is horizontally arranged at the seabed and is provided with a vertical guide rail; the gear set comprises a forward rotating gear, a reverse rotating gear, a power output gear, a driven gear and a reversing gear; a ratchet mechanism is arranged in both the driven gear and the reversing gear; the forward rotating shaft and the reverse rotating shaft are driven by a group of forward impellers and a group of reverse impellers respectively; unilateral stable power is provided for the generator by the power output gear through the output shaft by using the ratchet mechanisms; the generator is placed on the water surface; the safety of the generator can be effectively protected; and the impellers are kept under the environment of the minimum resistance to work in water and on the water surface through an integral suspending or floating mode of the impellers and the device and the structure and contour design of the impeller blades, so that tidal energy can be utilized to generate power by device with the maximum efficiency.

Description

technical field [0001] The invention relates to a power generation device, in particular to a tidal power generation device. Background technique [0002] The kinetic energy and potential energy of seawater in motion are collectively called tidal energy. my country's mainland has a long coastline and many islands. It starts from the mouth of the Yalu River in the north and ends at the mouth of the Beilun River in the south. It is more than 18,000 kilometers long. In addition, the coastline of more than 5,000 islands is more than 14,000 kilometers long, and the total length of the coastline is more than 32,000 kilometers. Therefore, tidal energy resources are very rich. of. According to incomplete statistics, the national tidal energy reserves are 190 million kilowatts, of which about 38.5 million kilowatts are available for development, and the annual power generation capacity is 87 billion kilowatt-hours, which is equivalent to more than 40 Xin'anjiang hydropower stations. ...

Problems solved by technology

[0004] The applicant applied for a utility model patent "Tidal Power Generation Device" on October 29, 2010, application number: 201020582585.x, which discloses a device that utilizes tidal power generation. And the reverse shaft to drive the generator to generate electricity. This kind of device is a structure that does not involve the impeller blades. At the same time, the device is greatly affected by ocean currents and typhoon factors, and the blades cannot work completely underwater. In addition, the protection efficiency of the generator is relatively low.
