Wave power generation device

Abstract

The invention relates to the technical field of power generation, and particularly discloses a wave power generation device. The wave power generation device comprises a float bowl arranged on the water surface and a power generation unit arranged under the water surface; a connecting rod is arranged between the float bowl and the power generation unit; the power generation unit comprises a firstpaddle structure and a second paddle structure which are coaxially arranged, and a generator is arranged between the first paddle structure and the second paddle structure; the generator comprises a stator structure and a rotor structure, the rotor structure can rotate relative to the stator structure, and the stator structure is fixed to the connecting rod; the first paddle structure is fixedly connected with the stator structure, and the second paddle structure is fixedly connected with the rotor structure; the rotating directions of the first paddle structure and the second paddle structureare always opposite; and when the first paddle structure and the second paddle structure rotate along with flowing of water, the generator generates electric energy. The wave power generation deviceis simple in structure, small in size and low in cost, can effectively resist impact, can generate power when waves rise or fall, and also improves the energy conversion efficiency.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to a wave power generation device. Background technique [0002] With the development of modern industry, the demand for energy is also increasing. Due to the depletion of traditional energy and the deterioration of environmental pollution, the development of new energy is imminent. To this end, people continue to explore and develop safe, clean and renewable new energy sources. The ocean area on the earth accounts for 72%. The total amount of theoretically renewable ocean energy in the world is 76.6 billion kilowatts, and the technically allowed utilization power is 6.4 billion kilowatts, which is about twice the current global generator capacity. Wave energy has its unique advantages. The energy density of wave energy is high, which is 4-30 times that of wind energy. Compared with solar energy, wave energy is not affected by the weather. In addition, because waves are ...

AI Technical Summary

Problems solved by technology

At present, there are many designs of wave energy power generation devices, but each structure has defects such as large volume, poor impact resistance, and low power density.

Since the power generation device will move up and down with the waves, the relative movement between the energy conversion part and the surrounding water is insufficient, thus affecting the energy conversion efficiency per unit area

In order to solve this problem, relevant personnel have considered many auxiliary methods, which relatively increased the implementation cost and failed to achieve the expected effect
