Rainwater and Sewage Diversion Device - Liquid-Operated Downward-Sliding Weir Gate
2023-11-21
In the water level control system for pre-ditching of drainage pipeline rainwater overflow, through weir gatesRegulating the water level of rainwater inside drainage pipes, but the weir gate structure is complex. For example, the downward-opening weir gate is primarily composed of a weir plate, a weir frame, and an oil cylinder. The weir plate and weir frame are made by bending and welding thin stainless steel plates. Due to the high sealing requirements of the weir gate, on-site assembly is challenging, so the main method is to fully assemble the entire structure in the factory and then install it on-site by crane.
The primary functions are water retention and flushing.Washing and draining.He can adjust the water storage volume or elevate the level of the drainage pipe.Generate powerful hydraulic waves to scour the sewers.The product can also be used to control the drainage volume of drainage facilities, primarily driven by hydraulic power. The material of the product is:Manufactured with precision using pressure-sealed technology to ensure product quality.
Ultrasonic level sensors detect water levels on both sides of the weir and convert them into electrical signals for the control system.
The control system drives hydraulic cylinders on both sides of the weir gate, which slide up and down within guiding grooves. Rubber sealing components are fitted on both sides and the bottom of the guiding grooves to ensure sealing (can be three-sided or four-sided sealing).
The hydraulic cylinder is equipped with a displacement sensor, allowing for precise control of the weir plate to stop at any position. In the event of a power outage, it can manage various functions such as upstream water level control, flushing, and prevention of backflow.

04 Technical Summary
In the water level control system for drainage pipeline rainwater overflow, the weir gate is used to control the liquid level of rainwater within the drainage pipe, but the weir gate structure is complex. For example, the downward opening weir gate is mainly composed of a weir plate, a weir frame, and an oil cylinder. The weir plate and weir frame are made by bending and welding thin stainless steel plates. Due to the high sealing requirements of the weir gate, on-site assembly is difficult, so the main method is to fully assemble it as an integral unit in the factory and then install it on-site by crane lifting.
During the on-site hoisting alignment, due to the main body of the weir frame being made of stainless steel sheet, using the method of pre-buried steel plate and reinforced steel bar alignment, i.e., embedding the steel plate during the pouring of the door slot, after the weir gate is hoisted into the door slot, welding the weir frame to the pre-buried steel plate with steel bars, this method can damage the weir frame and cause deformation, affecting the overall seepage prevention of the weir gate.
