Environmentally friendly surface hydroelectric power station

Abstract

The invention provides an environment-friendly water surface hydroelectric power plant which comprises iron tower supports, a water wheel supported to the tops of the iron tower supports through a water wheel centre shaft, a reduction box and an electric generator. The water wheel is evenly provided with a plurality of groove-type blades, the two ends of the water wheel centre shaft are supported to the tops of the corresponding iron tower supports through lifting mechanisms and move up and down to adjust the height of the water wheel, one end of the water wheel center shaft is connected with the input end of the reduction box through a crank type transmission device. According to the environment-friendly water surface hydroelectric power plant, the groove-type blades are adopted and are in holding type contact with water flow, stress is concentrated, the fluid potential energy can be received to the maximum degree, the rotation twisting force of the water wheel and the water wheel center shaft is increased, and the aims of energy conservation and efficiency improvement are achieved; in addition, the water wheel center shaft and the water wheel of the environment-friendly water surface hydroelectric power plant move up and down through the lifting mechanisms, the end of the water wheel center shaft outputs power through the crank type transmission device, normal transmission of power at different heights of the water wheel center shaft is guaranteed, impact damage of floating objects in a river on the blades during large waves and fast flow is avoided, and the electric generation capacity and the viability of the power plant under the extreme hydrologic condition are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of hydropower generation, and in particular relates to an environment-friendly water surface hydropower station. Background technique [0002] Hydropower is the most important form of human utilization of water energy. Hydropower is a non-polluting, renewable and clean energy. However, when building a hydropower station, it will cost a huge investment to block the dam, flooding a large area of ​​farmland, and causing a large number of immigrants to relocate. Moreover, the sedimentation caused by water storage has a great negative impact on the ecological environment of the river, especially in the river basins and complex geological areas where the ecological environment is very fragile in the southwest and northwest where dams are not suitable. The cumulative damage caused by natural conditions cannot be ignored. In order to solve the above-mentioned many problems exposed by dam blocking power generation, ...
