Multi-stage ski-jump energy dissipation drainage system

Abstract

The invention discloses a multi-stage ski-jump energy dissipation drainage system. The multi-stage ski-jump energy dissipation drainage system comprises a flip bucket, partition walls and a pluralityof flow guide channels, wherein the flip bucket, the partition walls and the flow guide channels are sequentially arranged in the water outlet direction of a diversion channel; a V-shaped flow guide wall is arranged on the flip bucket; the flow guide wall gathers water flow in the diversion channel to the flip bucket; water is lifted up by the flip bucket and then impacts into the flow guide channels; each partition wall is arranged on one side of the corresponding flow guide channel; a field tail water discharge area is formed by one sides of the partition walls and the wall, on one side, ofthe diversion channel; and an energy dissipation tail water discharge area is formed on the other sides of the partition walls and the wall, on the other side, of the diversion channel. The multi-stage ski-jump energy dissipation drainage system is applied to the tail end of a river diversion irrigation project with a relatively high water flow rate of a diversion river, and particularly has effects of reducing soil loss, collecting irrigation tail water and preventing river sediment deposition on farmlands with serious soil erosion. According to the multi-stage ski-jump energy dissipation drainage system, the water energy is utilized, energy conservation and environmental protection are achieved, meanwhile, the problems of water and soil loss and ski-jump energy dissipation are solved, and the comprehensive performance is good.

Description

technical field [0001] The invention belongs to the technical field of field engineering, and in particular relates to a multi-stage deflected flow energy dissipation drainage system. Background technique [0002] Field drainage system has always been an important part of field engineering. The commonly used water diversion irrigation method directly builds intake gates and barrages in the river for water intake. However, when this method is applied to rivers with rapid flow velocity and high sediment content, it is easy to aggravate the problem of soil erosion. In addition, the excess water energy is not fully utilized. A certain amount of energy waste is caused, and the excessive water flow rate also has a negative impact on agricultural production. If the tail water at the end of the diversion canal is used to dissipate energy for rivers with high water flow velocity at the water intake, the flow velocity can be slowed down while saving energy, which is beneficial to agr...
