Lever type river water depth control device

Abstract

The invention relates to a lever type river water depth control device, which belongs to the field of hydraulic engineering and comprises a square cylindrical control valve, a rope, a lever and a weight. The square cylindrical control valve is connected with one end of the lever through the rope, and the weight is disposed at the other end of the lever. A sliding chamber is reserved at the bottom of a retaining weir, and the square cylindrical control valve is disposed in the sliding chamber. A front baffle and a rear baffle are disposed at two ends of the square cylindrical control valve in the sliding direction. A bearing is disposed at the top end of the retaining weir, and the lever is disposed on the bearing. The valve of the lever type river water depth control device is opened or closed by the aid of hydrostatic pressure or lever acting force with no need of other power sources, and accordingly energy resources are saved. The square cylindrical sliding chamber is positioned at the river bottom, so that riverbed sediment in front of the weir can be discharged, sedimentation of silt and the like is reduced, and important significant to improving river water environment is achieved. The weight is adjustable in position, so that upstream water depth can be adjusted. The lever type river water depth control device is convenient in mounting, stable in operation and highly applicable.

Description

technical field [0001] The invention relates to a lever type ditch water depth control device. It belongs to the field of hydraulic engineering. Background technique [0002] Devices that adjust water depth through valves or gates are widely used in engineering, but there are fewer devices that can adjust water depth without external power. Gates or weirs are mostly used for channel and river water delivery in China. They all have obvious defects. At present, most of the gates in China are underflow gates. The disadvantage is that it is difficult to accurately control the upstream water depth. The fixed height weir also has great technical defects, and cannot adjust the upstream water depth. In view of the above problems, the present invention proposes a device for controlling water depth using the principle of leverage. Contents of the invention [0003] The present invention provides a lever-type ditch water depth control device aiming at the above-mentioned deficienc...
