Embodiment Construction

[0015] At the end of the facing slope of the dam, a rectangular water inlet pool (5) is set, and in the direction perpendicular to the dam crest (11), a headstock machine room (10) is set at the same height as the dam crest; the water inlet pool (5) Two gate holes (4) and inspection holes (12) are reserved in the upper part to install the folding cantilever gate (3); The self-weight of the gate and the hoist are used to realize the opening and closing function of the folding cantilever gate, and the water flow is controlled to enter the water inlet pool (5) and then flow into the water delivery tunnel (6). The maximum opening degree of the gate is limited by the gate limit stop (14).

Abstract

The invention relates to a collapsible cantilever gate type inlet structure applicable to a medium and small size reservoir water conveyance tunnel. On the tail end of an upstream batter of a dam, a rectangular water inlet tank is arranged; in a direction perpendicular to a dam crest, an open-close machine room is arranged at a position with the height equal to the height of the dam crest; and through controlling an opening degree of a collapsible cantilever gate, controlling the flow of the water conveyance tunnel..

Description

technical field [0001] The invention relates to a water inlet structure suitable for the inlet of a water delivery tunnel of a small and medium-sized reservoir. Background technique [0002] At present, the entrance forms of water delivery tunnels for small and medium-sized reservoirs are basically tower-type water delivery tunnel entrances, climbing tunnel water delivery tunnel entrances, cable-stayed gate entrances, tower-type water delivery tunnel entrances, and working towers are required for tower-type water delivery tunnel entrances. And the working bridge, the hoist machine room is set on the top of the tower to open and close the gate; the entrance of the water delivery tunnel of the climbing tunnel needs to be based on the terrain and the design of the dam. The management method is to open the water inlet in stages according to the water level of the reservoir. The import forms of these two water delivery tunnels are high in cost, long in construction period, compl...
