Novel wind-tidal combined power generation device

Abstract

The invention discloses a novel wind-tidal combined power generation device comprising a reservoir. Three faces of the reservoir is a foundation of concrete structure; the right side of the reservoiris a dam; the reservoir is in a hollow structure and a tidal power generation device is arranged inside the interior of the reservoir; a wind power generation device is arranged above the dam; a towerbody is fixed above the dam through a plurality of bolts; the wind power generation device and a third transmission shaft are connected to and engage to each other through gears; the wind power generation device is electrically connected to a battery pack; flow channels are evenly distributed at the bottom of the dam; silt barrier belts are respectively built on two sides of the dam; protection nets are distributed on the two sides of the inner portion of the flow channels; impeller supporting pillars are fixedly mounted inside the flow channels; and three-piece impellers are fixedly connected to the inner rotating portion of the impellers. According to the novel wind-tidal combined power generation device, the wind power generation device and the tidal power generation device are effectively combined, so that the rich offshore wind resource can be fully utilized and the investment and cost of infrastructure can be greatly reduced; the periodic power supply problem of tidal power generation can be effectively improved by wind power generation, and the electric can be continuously provided.

Description

technical field [0001] The invention relates to a power generation device, in particular to a wind-tidal combined power generation device. Background technique [0002] Wind power refers to converting the kinetic energy of wind into electrical energy. Wind is a kind of energy without pollution. It is very environmentally friendly to use wind power to generate electricity, and it can generate huge electric energy. Therefore, more and more countries pay more attention to wind power generation. Because there is no shelter, offshore wind power is more abundant and stable. During the development process, some problems need to be solved urgently, and a large amount of land is occupied. In order to ensure the stability of the wind power generation device, the base area is generally designed to be more than 10 times that of the tower body; the principle of tidal power generation is similar to that of ordinary hydropower generation.

Wind is a kind of energy without pollution. It is very environmentally friendly to use wind power to generate electricity, and it can generate huge electric energy. Therefore, more and more countries pay more attention to wind power generation. Because there is no shelter, offshore wind power is more abundant and stable. During the development process, some problems need to be solved urgently, and a large amount of land is occupied. In order to ensure the stability of the wind power generation device, the base area is generally designed to be more than 10 times that of the tower body; the principle of tidal power generation is similar to that of ordinary hydropower generation. The seawater is stored in the reservoir in the form of potential energy. Then, the seawater is released at ebb tide, and the difference between high and low tide levels is used to drive the water turbine to rotate and drive the generator to generate electricity. However, there are diurnal and tidal ranges in tidal energy. The state is unstable. If combined with wind power generation, this problem can be effectively alleviated. In addition, wind power generation and tidal power generation have high requirements for infrastructure, and the initial investment is large. If the two are effectively combined, a lot of infrastructure costs can be saved. Therefore, we invented a A new type of combined wind and tidal power generation device is necessary
