Problems solved by technology

However, most of the existing vertical axis turbines use the circular rotation of the blades to convert the ocean current energy into mechanical energy. According to the existing research results, the main power generation area is the windward side, but the windward side accounts for a larger proportion of the circular rotation. Low, combined with the existence of a large interception area to generate resistance or no power, resulting in overall low efficiency

Abstract

The invention discloses a diversion type biaxial membrane swing type water turbine. A diversion cover, a turbine support and a film blade structure are used to form a water turbine structure with a diversion effect. A diversion cover is respectively arranged on both sides of the turbine support. One side of the air guide cover is provided with a rectangular opening, so that the angle between the plane where the side of the air guide cover is provided with the rectangular opening and the plane where the axes of the two rotating support shafts are located is an acute angle. The guide vane on the flow cover is the position of the flow guide cover, which guides the water flow entering the turbine bracket, accelerates the water flow to the upstream surface, and at the same time reduces the water flow to the reverse water surface, reducing the generation of resistance. At the same time, combined with the film blade structure , the same direction torque can be received on both the downstream surface and the upstream surface, thus greatly improving the efficiency of the whole machine. The conversion rate of water flow transmission.

Description

technical field [0001] The invention belongs to the technical field of ocean energy power generation, and in particular relates to a diversion type biaxial membrane swing water turbine. Background technique [0002] With the rapid development of urban modernization and industrialization, energy has already become an important factor affecting the rapid economic and social development. Commonly used traditional energy such as coal, oil, natural gas and other fossil fuels cannot be regenerated in a short period of time, and will cause damage to the natural environment while being consumed. For the sustainable development of the environment, it is imminent to develop alternative energy sources. [0003] As a new type of green renewable energy, ocean energy mainly includes tidal energy, tidal current energy and wave energy. my country has a long coastline and vast sea area, and has abundant ocean energy reserves. It is one of the areas with the highest power density of tidal c...
