An ecological artificial river channel downstream of the reservoir with the function of filtering and generating electricity

Abstract

The invention discloses an ecological artificial channel with filtering and electricity generation functions at a downstream position of a reservoir. The ecological artificial channel comprises two rows of river retaining walls respectively arranged in the artificial channel in the river flow direction, the two rows of river retaining walls are respectively arranged close to the two sides of the channel, an inner area between the two rows of the river retaining walls is an inner channel, and an area between one river retaining wall and the corresponding side of the channel is an outer channel; the lower portion of each river retaining wall is provided with water flow holes, the water holes are internally provided with rotary turbines used for electricity generation, and closing valves are arranged at the positions of the water flow holes; one surface, close to the corresponding outer channel, of each river retaining wall, is provided with lifting inserting boards, each lifting inserting board is provided with a filter casing used for filtering mud in water, the inner channel is internally provided with a dirt interception layer, the dirt interception layer is internally provided with water flow through holes, and the upper surface of the dirt interception layer is provided with dirt accumulation areas. Compared with the prior art, the timing reservoir sluicing is utilized by the ecological artificial channel with the filtering and electricity generation functions at the downstream position of the reservoir, so that when the double-layer-design artificial channel is filled with water, the hydroelectric generation is achieved through the utilization of the water level difference by the inner and outer channels; besides, rubbish and foreign matters in a river can be filtered, the water quality is purified, and energy conservation and environment protection are achieved.

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
