Two-way water stop gate with discrete sealing adjustment structure

Abstract

The invention discloses a two-way water stop gate with a discrete sealing adjustment structure. The two-way water stop gate comprises a door frame, a gate, a door frame fixing seat, sealing adjustment mechanisms and a hydraulic driving rod, wherein the door frame is fixed to a civil engineering base through the door frame fixing seat; a longitudinal sliding groove is formed in the door frame, the gate is installed in the longitudinal sliding groove, and a circle of sealing ring is installed at the edge of the inner side surface of the gate; a plurality of protruding pressure bearing blocks are respectively arranged at the left and right edges of the outer side surface of the gate at equal intervals, and the sealing adjustment mechanisms are fixed to the door frame fixing seat, correspond to the pressure bearing blocks one to one and are tightly pressed on the pressure bearing blocks; and the oil cylinder end of the hydraulic driving rod is fixed to the top of the door frame, and the telescopic rod end of the hydraulic driving rod is fixed to the gate. According to the two-way water stop gate, the design of the sectional type pressure bearing blocks is adopted, so that the sealing effect of the gate can be guaranteed, the cost of the sealing structure can be greatly reduced, and the field maintenance workload and the maintenance cost are reduced.

Description

technical field [0001] The invention relates to a two-way water-stop gate, in particular to a two-way water-stop gate with a discrete sealing adjustment structure. Background technique [0002] Gates are mainly used in urban drainage, flood control and environmental protection projects. They can be used to intercept water flow, control water level, regulate flow and prevent sewage discharge. The two-way water stop gate is mainly used to intercept the water flow in the positive and negative directions. The water level is monitored through the water level monitoring system, and the opening and closing of the gate is jointly controlled by the rain gauge. [0003] The existing two-way water-stop gate realizes the two-way water-stop of the gate through wedges pressing the gate and the sealing ring. The sealing of this kind of gate is mainly achieved by adjusting the wedge to press the bearing plate, and the bearing plate presses the gate and the sealing ring to realize the seali...

AI Technical Summary

Problems solved by technology

The sealing of this kind of gate is mainly achieved by adjusting the wedge to press the bearing plate, and the bearing plate presses the gate and the sealing ring to realize the sealing of the gate. However, if the stroke of the gate is very long, the length of the bearing plate will be very long. It greatly increases the production cost of the pressure bearing plate, especially in the case of a large demand for the gate, the cost of the gate also increases accordingly

[0004] In addition, the pressure bearing plate is welded on the gate track support, which will be impacted by external forces during long-term use. Once it is damaged or deformed, there will be problems with the gate seal. It is necessary to replace the entire pressure plate, which increases the maintenance cost and workload of the gate
