Elastic overflow weir

Abstract

The invention relates to an elastic overflow weir. The bottom edge of a weir plate is hinged on a fixed base, a sealing rubber sheet is arranged at the hinged part of the weir plate and the fixed base, the upper surface of the weir plate is of an arc surface, the sensitivity is high, the overflow resistance is low, the overflow rate is fast, and the overflow amount is larger, the closure effect is stable, and the water discharge of large quantity is realized; the back surface of the weir plate is linked with at least a cluster spring fixed on the fixed base, thus, the overflow weir is enabled to have simple outline structure, the parts are reduced, the assembly and the maintenance are convenient, the overflow weir is not limited by the landform, the rise and the fall of the weir plate are stable, and the overflow weir of 1 meter width can be used for replacing a fixed weir of 8 to 15 meter width.

Description

technical field [0001] The invention relates to an elastic overflow weir for intercepting and discharging water in water conservancy projects and for controlling water interception and large water discharge in urban water supply and drainage systems. Background technique [0002] In the water system pipe network, in order to achieve the purpose of not only controlling the water interception flow, but also solving a large amount of water discharge, the overflow weir is generally used for control. At present, a fixed weir is usually used to control the interception flow. The fixed weir is of a fixed height and mainly plays the role of interception. The water exceeding the interception flow is discharged over the top of the fixed weir, and its overflow control effect is not good. An adjustable buoyancy flap weir that replaces the fixed weir, the weir plate is hinged on the fixed base, the upper surface of the weir plate is connected to the buoy by the traction rope and the fixe...

AI Technical Summary

Problems solved by technology

Compared with the fixed weir, the overflow of the flap weir is larger, but it has the following disadvantages: the fixed bearing of the buoy that controls the operation of the flap weir is easily restricted by the installation site, the shape and structure are complex, the installation is inconvenient, and the sensitivity and efficiency of the weir are difficult to control; The upper surface of the weir plate is flat, the water resistance is large, and the movement of the weir plate is not stable.
