Problems solved by technology

At present, wind power is widely used, but due to the instability of wind resources, wind power is hindered by regional and seasonal obstacles, and wind power alone is far from meeting people's needs.
For the most abundant water resource on the earth, its stored energy is undoubtedly greater. However, since human beings have not yet made new breakthroughs in hydropower technology, its technology only stays in hydro turbine power generation, and this kind of hydropower technology is limited. It is more difficult to construct, and generally can only be used in rivers and reservoirs; for ocean power generation, its technology is not yet mature, and the energy generated by ocean currents and waves cannot be well utilized. The direction of future research

Embodiment 1

[0020] Such as figure 1 , 2 As shown, a vertical axis hydroelectric generator includes a pile foundation 12 deep into the seabed 2, a tower column built on the pile foundation 12, a generator set installed on the tower column, and an impeller 4 connected with the generator set. The tower includes an underwater platform 11, a support column 3 and an above-water platform 6, the underwater platform 11 is fixedly connected to the top of the pile foundation 12, the support column 3 extends to the water surface 1 and is connected and fixed with the above-water platform 6, and the above-water platform 6 is higher than water surface 1. The underwater platform 11, supporting column 3 and above-water platform 6 are integrally molded by reinforced concrete. The integrally poured tower column is stronger and larger, can resist the perennial impact of water flow, and can support the huge impeller 4 to rotate in the water. It is also possible to cancel the underwater platform 11, and the ...

Embodiment 2

[0027] Such as image 3 As shown, a vertical axis hydroelectric generator includes a pile foundation 12 deep into the seabed 2, a tower column built on the pile foundation 12, a generator set installed on the tower column, and an impeller 4 connected with the generator set. The tower includes an underwater platform 11, a support column 3 and an above-water platform 6, the underwater platform 11 is fixedly connected to the top of the pile foundation 12, the support column 3 extends to the water surface 1 and is connected and fixed with the above-water platform 6, and the above-water platform 6 is higher than water surface 1. The supporting column 3 is cast from reinforced concrete, and the construction period of this kind of supporting column 3 is shorter, and it has a certain strength guarantee.

[0028] The support column 3 is a hollow structure, and the support column 3 is provided with several observation ports 13, and the observation ports 13 are provided with pressure-re...

Abstract

A vertical-shaft hydroelectric generator comprises a pile foundation deep into a seabed, a tower column built on the pile foundation, a power generator set installed on the tower column and an impeller connected with the power generator set. The tower column comprises an underwater platform, a supporting column and a water platform. The underwater platform is fixedly connected with the top of the pile foundation, the supporting column extends to the water surface and is fixedly connected with the water platform, and the water platform is higher than the water surface. The power generator set is arranged on the water platform, the impeller comprises lift-type blades installed on a rotary main shaft outside the supporting column, and the impeller is arranged in water. The lift-type blades can rotate in one direction under non-directional air flow and under non-directional water flow, and accordingly the lift-type blades of the vertical shaft can rotate in water in one direction, the lift-type blades of the vertical shaft are deep underwater on the basis and can rotate through scouring of the water flow or ocean currents, and hydroelectric generation can be achieved through the lift-type blades and the power generator set.

Description

technical field [0001] The present invention relates to hydroelectric power generation, in particular vertical axis hydroelectric generators. Background technique [0002] Energy shortage and environmental pollution are two major problems facing mankind. Vigorously developing clean and renewable energy has become an important strategic measure for the sustainable development of world energy. Both hydroelectric power generation and wind power generation are non-polluting green power generation methods. At present, wind power generation is widely used, but due to unstable wind resources, wind power generation is hindered by regional and seasonal factors, and relying solely on wind power generation is far from meeting people's needs. For the most abundant water resource on the earth, its stored energy is undoubtedly greater. However, since human beings have not yet made new breakthroughs in hydropower technology, its technology only stays in hydro turbine power generation, and...
