Problems solved by technology

[0002] Most of the existing hydropower generation devices are installed in larger water conservancy projects. Due to the relatively large size, they do not pay too much attention to the damage of related parts of the hydro turbine.
Due to the influence of internal temperature, pressure and obstacles, the flow direction of the water flow is not completely consistent, and it is easy to form a vortex locally, and such a vortex will vibrate the impeller left and right, which will damage the fixed parts of the impeller for a long time
And for small and medium-sized hydroelectric power generation devices, the requirements for water flow speed are relatively strict. If the water flow speed is too fast, the impeller will rotate too fast, resulting in accelerated damage to gears, bearings and other accessories, but if the water flow speed is too slow, it will cause Defects such as low power generation efficiency

Abstract

The invention relates to a durable hydroelectric device comprising a culvert, a first electricity generation cavity, a second electricity generation cavity and an electricity generator unit. By setting an overall device structure, especially the specific structure of the first electricity generation cavity, no matter what the water flow condition is, namely whether a water flow is turbulent or slow, the maximized electricity generation operation can be achieved; and meanwhile, damage to a part along with changing of the water flow speed does not occur, and the durability and the electricity efficiency of the hydroelectric device are overall improved.
