Independent water intake tower structure for entrances of water diversion tunnels of medium and small-flow water reservoirs

Abstract

The invention discloses an independent water intake tower structure for entrances of water diversion tunnels of medium and small-flow water reservoirs. The independent water intake tower structure comprises a trash rack, a stop log gate, a stop log gate warehouse, an overhauling gate, an overhauling gate warehouse, an opening and closing gantry crane, a trash cleaning grab bucket warehouse, a traffic bridge and a water diversion tunnel, wherein the trash rack, the stop log gate, the stop log gate warehouse, the overhauling gate, the overhauling gate warehouse and the trash cleaning grab bucketwarehouse are sequentially arranged along the water flow direction, so that one opening and closing gantry crane on a top platform of the water intake tower can be used for controlling the stop log gate and the overhauling gate, the stop log gate is lifted and lowered by the opening and closing gantry crane, and the surface water of the water reservoir is fetched for the ecological flow of downstream riverway and the farmland irrigation water. The independent water intake tower structure has the advantages that the stop log gate and the overhauling gate can be controlled by one gantry crane,so that the arrangement of a bent frame at the top of the tower and the opening and closing gantry crane in an opening and closing room is not needed; the quantity of excavation and support engineering of larger edge slopes due to side gate warehouses of the water intake tower can be reduced.

Description

technical field [0001] The invention relates to the entrance of a water diversion tunnel on the bank of a water conservancy and hydropower project, in particular to an independent water inlet tower structure used for the entrance of a water diversion tunnel of a reservoir with small and medium flows. Background technique [0002] The flow range of water diversion from the bank of the water conservancy project is generally small and medium flow. The water inlet floor elevation of the water diversion tunnel is below the dead water level of the reservoir, and the water temperature of the reservoir is low, which cannot meet the water temperature requirements of ecological water for downstream rivers and water for farmland irrigation. Stratified water intake facilities to draw surface water from reservoirs. [0003] The traditional treatment method for independent water inlet tower structures with small and medium flow rates is as follows: arranging a stacking beam door storehous...

AI Technical Summary

Problems solved by technology

The disadvantage of this method is that it is necessary to set up the stacked beam door storehouse on the side of the water inlet tower, the opening and closing equipment of the stacked beam door, the bent frame on the top of the tower, and the hoisting machine room. The opening and closing operation is complicated and the operating cost is high; The slope disturbance area is large, and the support cost is high; the construction is complicated
