A double-layer artificial river downstream of a reservoir

Abstract

The invention discloses a double-layer artificial river channel of a reservoir down stream. The double-layer artificial river channel comprises two rows of river blocking walls which are arranged in the artificial river channel in the direction of a river respectively, the river blocking walls are arranged close to two sides of the river channel respectively, a region inside the river blocking walls serves as an inner river channel, and a region ranges from the river blocking walls to one side of the river channel serves as an outer river channel; positions close to the lower portions of the river blocking walls are provided with water flowing holes, rotating turbines used for generating power are arranged in the water flowing holes, and closing valves are arranged at the water flowing holes; a lifting and dropping plug plate is arranged on one face of the river channel, close to the outside, of the river blocking walls, and a filtering cover used for filtering dirt in water is arranged on the lifting and dropping plug plate. Compared with the prior art, by means of a reservoir, the water is discharged by opening the valve on time, when the water is filled in the double-layer designed artificial river channel, the waterhead is used by the inner river channel and the outer river channel, so that the hydroelectric generation is achieved, the energy is saved, and the environment is protected.

Description

technical field [0001] The invention relates to an energy-saving and environment-friendly artificial river, in particular to an artificial river downstream of a reservoir using water level difference to generate electricity. Background technique [0002] The function of the reservoir is usually to reduce the flood peak flow entering the downstream river, so as to reduce the flood disaster. The opening of the reservoir is generally regular, and the water storage in the downstream river fluctuates greatly, the water level changes, and the gravity potential energy of water is invisible On the other hand, urbanization is accelerating, large areas of land are developed, vegetation coverage is reduced, the original ecosystem in the area is destroyed, and the phenomenon of soil erosion is intensifying. How can we effectively solve it? above question. [0003] For example, the utility model with the patent No. 201220680574.4 is a structure for transforming a muddy water channel wit...

AI Technical Summary

Problems solved by technology

The utility model converts muddy water channels with small flows, including brooks and ditches, into clear water after filtration, and uses the filtered clear water to build clear water channels as the ecological landscape of the city, effectively improving the city's appearance and providing people with Good living environment; the patent has the following defects: ①The environmental changes and disturbances of the original river are relatively large, destroying the original ecological environment; ②The engineering volume is large; ③The ecosystem is monotonous; ④The coordination with the landscape on both sides of the river is poor
