The invention provides a stop log gate device of a water inlet of a power station for layered water taking. The stop log gate device comprises trash rack piers, trash rack gate grooves, spare trash rack gate grooves and trash racks; the trash rack gate grooves are correspondingly formed in the side walls of the front ends of every two adjacent trash rack piers, and the spare trash rack gate grooves are correspondingly formed in the side walls of the rear ends of every two adjacent trash rack piers. The device is characterized by further comprising fold line type slab stop log gates which are disposed in the trash rack gate grooves, and the trash racks are disposed in the spare trash rack gate grooves. Compared with traditional slab stop log gates, the stop log gate device has the advantages that under the case of maintaining the water blocking height of the stop log gates unchanged, that is to say that the effect of improving the ecological environment of a downstream riverway is unchanged, the total head loss of a water inlet segment of the power station can be reduced, and the power generation benefit of a hydropower station is increased. The stop log gate device has a good social benefit and a good economic benefit.
Description
technical field [0001] The invention relates to the fields of water conservancy and hydropower construction and development and ecological environment protection, in particular to a stacking beam door device for layered water intake at a water inlet of a power station. Background technique [0002] With the continuous development of water conservancy and hydropower projects, while bringing huge comprehensive benefits, their environmental problems have become increasingly prominent and have attracted great attention from the society. Ecological environment protection is a sensitive issue faced by water conservancy and hydropower projects at present. Especially after the completion of some high-dam hydropower stations, the low-temperature water released by them will have a serious impact on the ecological environment of the downstream river, directly threatening the survival of various aquatic organisms in the river. To survive, setting up a layered water intake structure in f...
