Abstract

The invention relates to a shore-based hydroelectric power generation system which belongs to the technical field of hydroelectric power system structures. The shore-based hydroelectric power generation system comprises a hydroelectric power generation device, wherein a concrete riverbed is arranged at the bottom of the hydroelectric power generation device; the hydroelectric power generation device comprises a concrete shore dam and a water turbine-generator set arranged on the concrete shore dam, wherein the concrete shore dam is arranged on the concrete riverbed, and a driving shaft penetrates through the concrete shore dam; the water turbine-generator set comprises a bidirectional-rotation power generator arranged on the driving shaft; and a primary gearbox and a secondary gearbox arerespectively arranged at the left side and the right side of the bidirectional-rotation power generator, wherein the primary gearbox is sequentially connected with a small primary driving wheel, a large primary driving wheel and a water wheel contacted with river water which are fixed through a primary water wheel shaft, and the secondary gearbox is connected with a small secondary driving wheel,a large secondary driving wheel and a water wheel which are fixed through a secondary water wheel shaft. The invention has reasonable structure and design and high power generation efficiency, does not influence shipping, can not cause sediment accumulation at the riverbed and is in harmony with nature as well as green and environment-friendly.

Description

technical field [0001] The invention relates to a shore-based hydropower generation system, which belongs to the technical field of hydropower system structures. Background technique [0002] Generally, hydropower generation requires the construction of a dam to block the rise of the river water level and cause a certain drop and flow, and use the potential energy of the water to drive the water wheel to generate electricity. Due to the need to intercept rivers, the construction of dams is not only expensive, but also has a long construction period, damages the ecological environment, affects shipping, and requires a large number of immigrants. Therefore, the practice of blocking rivers and damming hydropower stations has been opposed by environmental protection organizations around the world. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings of the above-mentioned prior art, and provide a shore-based hydroelectric power ...
