Abstract

The invention discloses a horizontal shaft floating type tidal current energy power generation device formed by single point mooring. According to the key points of the technical scheme, the horizontal shaft floating type tidal current energy power generation device formed by single point mooring comprises a floating carrier and impeller devices connected to the lower end face of the floating carrier. The floating carrier is connected with a single point mooring device. The floating carrier is provided with an orientation rudder for guiding the floating carrier. According to the horizontal shaft floating type tidal current energy power generation device formed by single point mooring, the weather vane effect can be utilized to reduce resistance, tidal currents are aligned with automatically, the water plane area is reduced, and thus the wave loading is reduced.

Description

technical field [0001] The invention relates to the field of tidal current energy generation, in particular to a horizontal axis floating tidal current energy generation device in the form of single point mooring. Background technique [0002] Ocean tidal current energy is a kind of marine renewable energy, which can convert the huge kinetic energy contained in the ocean tidal current into electrical energy and utilize it through energy conversion equipment. Compared with other renewable energy sources, ocean tidal current energy has many advantages, which are mainly reflected in: high energy density, strong predictability, stable load and abundant reserves. my country has a coastline as long as 18,000 kilometers, an ocean land of more than 3 million square kilometers, and the theoretical average power generation of tidal current energy exceeds 13,000 megawatts. According to statistics, across the country, there are more than 130 waterways that have the development prospect...
