Polygonal intake tower for specified-height water intaking at reservoir water tunnel entrance

Abstract

The invention discloses a polygonal intake tower for specified-height water intaking at a reservoir water tunnel entrance. The polygonal intake tower comprises a plurality of bulkhead gates, fixed trash racks fixed to the front of the bulkhead gates, an opening and closing machine room located on the tower top, a plurality of winch type gate hoists, a water delivery tunnel and a traffic bridge. The cross section of a intake tower is regular polygonal. The bulkhead gates are annularly arranged at different elevations along the sidewall of a tower body of the regular polygonal intake tower. Thewinch type gate hoists are arranged in the opening and closing machine room on the tower top corresponding to the hoisting bulkhead gates. The bulkhead gates are wound and unwound through the winch type gate hoists to achieve the purpose of specified-height water intaking. The polygonal intake tower is novel in structure, beautiful and practical in appearance and suitable for reservoir water intake engineering.

Description

technical field [0001] The invention relates to a water intake tower structure of a hydraulic structure, in particular to a polygonal water intake tower used for water intake at a specified height at the entrance of a water delivery tunnel of a reservoir. Background technique [0002] To take water from the reservoir, in order to meet the requirements of water quality, water temperature, etc., it is necessary to take water in layers. The structure of the water intake tower needs to adapt to the change of the water level for water intake in layers. [0003] At present, most of the structure types of stratified water intake towers use stacked beam doors to control stratified water intake. The disadvantages are that when the water level changes greatly, the gate size is large, special gate storage is required, and the structure is more complicated. And the use of the stacked beam door can only take the surface water of the reservoir, and cannot reach the purpose of taking water...

[0003] At present, most of the structure types of stratified water intake towers use stacked beam doors to control stratified water intake. The disadvantage is that when the water level changes greatly, the gate size is large, and special gate storage is required, and the structure is more complicated.

And the use of the stacked beam door can only take the surface water of the reservoir, and cannot achieve the purpose of taking water at the specified height of the reservoir
