Abstract

The invention discloses a novel matched variable slope spillway-based flood discharging system. The system is characterized by comprising a reservoir (1), wherein the reservoir (1) comprises a water outlet, a reservoir bank (10) positioned below the water outlet and a sluice (13) of which the bottom end is in contact with the reservoir bank (10); sliding rails (4) are symmetrically arranged at the left and right ends of the water outlet, and each sliding rail (4) is of a cambered structure; the top end of a spillway (5) is arranged on the sliding rails (4), and moves on the sliding rails (4), and the bottom end of the spillway (5) is seamlessly connected with a flip bucket (9). The novel matched variable slope spillway-based flood discharging system has excellent energy dissipation effects, and can be adapted to different flood discharging tasks, the jet trajectory length can be controlled, downstream erosion can be reduced, and downstream protection work can be protected.

Description

technical field [0001] The invention relates to a novel supporting flood discharge system based on a variable-slope spillway, in particular to a novel matching flood-discharging system based on a differential pick-up and a variable-slope spillway, and belongs to the technical field of water conservancy engineering. Background technique [0002] At present, there is no variable-angle spillway at home and abroad, and the proposal of a variable-slope spillway provides a new idea for the design of a bank spillway. Since the flow of the river is constantly changing with the seasons and time, the flood volume in the wet season is also constantly changing. Faced with different flood discharge tasks, the fixed spillway projecting water tongues will change accordingly. Design of downstream anti-scour facilities. The variable-slope spillway can change the slope angle to control the jet of water at the ridge, so that it can achieve the best energy dissipation effect and reduce downstr...
