A swinging tidal current energy generator with a gravity base

Abstract

The invention discloses a swing-type tidal current energy power generator with a gravity base. The power generator comprises the base, a power generation part, a pressure part and a locking part whichare arranged from bottom to top in sequence. The base is arranged on a seabed, a vertical rod is movably arranged in the middle of the locking part, penetrates through the locking part from top to bottom and extends into the pressure part, a cylindrical swing column is installed at the upper portion of the vertical rod and located in a sea tidal current field and can periodically swing under thefunction of tidal current, and the vertical rod is driven by the swing column to reciprocatingly vibrate to generate positive and negative pressure to suck external water into the pressure part and push a water turbine in the power generation part to rotate to generate power. The swing-type tidal current energy power generator is located in the current field, is a simple cylinder with a circular cross section and can adapt to the change of the tidal current direction in the sea.

Description

technical field [0001] The invention belongs to the field of marine renewable energy development, and relates to the acquisition, transformation and storage technology of ocean tidal current energy, in particular to a swing type tidal current energy generator with a gravity base. Background technique [0002] The ocean is rich in renewable energy, such as tidal current energy, wave energy, wind energy, etc. Because this kind of energy is clean and pollution-free, compared with traditional coal and nuclear energy, it is more in line with people's increasing environmental protection requirements, and has the advantages of inexhaustibility and renewability, which makes the development of marine renewable energy acquisition and conversion technology Has broad development prospects. Because of its clear regional distribution and stable flow field, tidal current energy has become an important development target in the field of marine new energy. [0003] At present, there are ma...

Problems solved by technology

Although this type of device can achieve a certain effect, there are still some disadvantages. For example, the direction of the tide in the sea is not fixed, and the upstream direction of the turbine cannot be adjusted generally, which affects the power generation efficiency; The construction operation in the environment is often difficult; the upstream surface of the turbine is relatively large, and after being arranged in an array in the sea, it will form a certain barrier to marine organisms, which has adverse environmental impacts
