Abstract
The invention discloses a device for generating power by using naturally flowing river water. The device comprises at least two abreast floating platforms, wherein a blade runner is arranged between every two adjacent floating platforms; a main shaft is arranged at the center of the blade runner; bearings for supporting the main shaft are arranged on the floating platforms; the main shaft is also connected to a speed reducer and a power generator; the main shaft rotates to drive the power generator to generate power; the upstream ends of opposite surfaces of the adjacent floating platforms are inversely splayed, so that the speed of water flow in a blade runner region can be increased; the upstream faces of blades on the blade runner are cambered, so that the water flow can be easily concentrated into cambered slots in the blades when being in contact with the blades, and the kinetic energy and the potential energy of water can be converted into electric energy to the maximum extent. The device disclosed by the invention is simple in structure, smaller in investment and easy to implement, and is very suitable for power generation on a small-size river; furthermore, a water retaining dam is not needed, so that the surrounding ecological environment cannot be affected.
Description
Technical field
The present invention relates to the device that a kind of river that utilizes natural flow generates electricity.
Background technique
Hydroelectric basic principle is to utilize the height of water, and hydrous water turbine generator produces electric power, namely utilizes the potential energy of water to transfer the mechanical energy of water wheels to, then with mechanical energy pushing generator, and obtain electric power.Utilize water for producing electric power at present adopt river upstream building check dam, increase the height of water and generate electricity, this method is applicable to medium-and-large-sized river, and cost is higher, application is restricted.
