Self-regulation siphon priming device suitable for water quantity change

Abstract

The invention relates to a self-regulation siphon priming device suitable for the water quantity change. The self-regulation siphon priming device comprises a grating, a passage cross section regulation unit, a siphon pipe ascending section, a siphon pipe parallel section and a siphon pipe descending section, the siphon pipe ascending section, the siphon pipe parallel section and the siphon pipe descending section are sequentially communicated, the siphon pipe ascending section is provided with the passage cross section regulation unit and is used for controlling the pipe diameter of the siphon pipe ascending section, and the water passage cross section area is changed accordingly. The self-regulation siphon priming device is compact in structure and small in arrangement floor space; and the self-regulation siphon priming device automatically changes the size of an air bag according to the water quantity and water level, and the full-automatic operation is relatively simple and effective.

Description

technical field [0001] The invention relates to the improvement of a water diversion device, more specifically, to a self-adjusting siphon water suction device suitable for changing water volume. Background technique [0002] The working principle of the siphon tube is: first discharge the air in the tube to form a certain degree of vacuum in the tube. Since the pressure of the inlet water flow is higher than the atmospheric pressure, the water flow can reach a higher position and overcome obstacles. Under the action of the upstream and downstream water level difference continue to flow downstream. In hydropower stations and water engineering, the way of attracting water by the rainbow has become a relatively important practical application because of its simplicity, high efficiency, and no need for additional power. In response to the country's requirements for the treatment of black and odorous water bodies, it is often necessary to clean up the sediment in many small riv...
