Description

Technical Field

[0001] The invention relates to the technical field of high mountain water conservancy power generation, and mainly to a method for arranging a water conservancy power generation device for mountain surface runoff and a power generation system thereof. Background Art

[0002] High-speed water flow contains a large amount of kinetic energy. Because runoff, streams or rivers have a generally constant flow in the drainage channel, it is advantageous to use such water flow to generate electricity. However, slow-flowing water may not have sufficient speed to generate sufficient power. In order to solve the above problems, the prior art, such as the patent document with publication number CN108150336A, discloses a portable generator that generates electricity using water flow and vibration. The above generator can be adapted to an environment with a slower water flow and effectively achieve the purpose of slowing down the water flow.

[0003] For example, the National Alpine Skiing Center, located in the southern foot of Xiaohaituo Mountain in the northern core area of ​​the Yanqing competition area, has the characteristics of large height difference of mountain terrain, vertical drop of nearly 900m, dense contour lines and large slope. In winter, the above-mentioned alpine skiing center needs artificial snowfall to form ski tracks for competitions and mass entertainment. After the snow season ends, the snow with a thickness of at least 40cm melts and forms runoff. How to effectively utilize alpine snowmelt, alpine streams and other flowing water is a technical problem that technicians in this field urgently need to solve.

[0004] In the prior art, a variety of micro-power generation equipment has been designed to achieve mountain surface runoff power generation. Because the site selection of hydropower generation needs to consider multiple factors, including dry and wet areas, river recharge, basin area or catchment area, etc. At the same time, the site selection is also closely related to the degree of terrain drop on the site. However, the prior art lacks a method for analyzing and pre-reading the terrain slope, runoff, etc., and calculating the layout of small hydropower generation resistor modules suitable for snow melting and flood discharge.
