Description

technical field [0001] The invention relates to the technical fields of marine engineering, civil engineering, hydroelectric power generation engineering, wind power generation engineering, energy engineering, and meteorological and climate engineering. Background technique [0002] Ocean current and ocean current energy are the largest reserves of hydraulic energy. Its energy sources are wind energy and the kinetic energy of the earth's rotation. It is estimated that the global ocean current energy is as high as 5×10 12 KW (5 trillion KW). The energy density of ocean currents can reach 20kw / m 2 , which is dozens to hundreds of times that of other clean energy sources such as solar energy, wind energy, and biomass. It is difficult for humans to exploit this resource on a large scale. There are three main difficulties: (1) the flow velocity is slow, and the average flow velocity of no ocean current exceeds 2 m / s, which is the lowest flow velocity that can be developed and...

Problems solved by technology

In addition, the development of wind energy has the following three shortcomings: (4) The high-altitude resources above 150 meters above the ground are not fully utilized, and the wind strength in the high-altitude stratosphere is 50-100 times that of the ground; (5) Low-altitude and low-speed wind resources are not fully utilized. , wind energy with an average wind speed lower than 4 m / s accounts for the vast majority of low-altitude wind resources; (6) Traditional wind turbines use speed-type wind rotors without ducts instead of pressure-type wind turbines with ducts. Wind wheels (such as water pumps are pressure-type water wheels); speed-type wind wheels require a wind speed of 3-16 m / s, and wind energy above or below this wind speed is wasted. too low
