Problems solved by technology

However, the implementation of wave power generation with the existing mature technology has the following disadvantages: 1. The oscillating water column wave energy device and the pendulum wave energy device require a hydraulic transmission shaft, so the cost is expensive and the cost performance of power generation is not high; 2. These devices require mechanical transmission. Secondary energy conversion, large friction loss, low conversion efficiency, 3. The generator is huge in size, requiring a relatively large wave height
The disadvantage is that the construction of the power station has requirements on the terrain and is not easy to promote

Abstract

The invention discloses a novel floater type tide and sea wave power generation device which comprises a cylinder, wherein the inner wall of the cylinder is embedded with a power generation coil, the outer wall of the cylinder is provided with blades, the center of the cylinder is embedded with a magnetic pole of a permanent magnet, the cylinder is sealed by adopting a sealing ring, two ends of the cylinder are provided with ladder-shaped wave flow collection plates which can generate induced currents by using wave flow in a horizontal direction and wave vibration, the generated induced currents are used for charging a battery after rectified, and a stable DC (direct current) is output, and then is converted into a power frequency AC (alternating current) through current transformation.

Description

technical field [0001] The invention belongs to the field of marine energy utilization and renewable energy power generation, and relates to a device for generating electricity by using tide and sea wave kinetic energy. Background technique [0002] Energy security has become a major global challenge, which is related to national security and social development. The limitedness of fossil energy and its greenhouse gas effect have forced countries all over the world to find ways to invest a large amount of scientific research resources in the research and development of green energy technologies. In addition to using natural resources such as wind energy, solar energy, geothermal energy, and nuclear energy, wave power generation is booming and has gradually become a new energy source that countries are competing to develop. The development of efficient and cost-effective wave power generation technology has huge economic and social benefits for my country's current environmen...
