Upturning dam gate capable of realizing instant self-locking control

Abstract

The invention discloses an upturning dam gate capable of realizing instant self-locking control. The upturning dam gate comprises a gate body whose top is rotationally connected to the top of a closure port, a left embedded bracket, a right embedded bracket, and a wedged base; the top of the gate body is connected to the top of the closure port for rotary opening through a double-lug bracket, a hinge shaft, a gate extension oil cylinder and a tension bracket; limiting modules are connected between the left embedded bracket, the right embedded bracket and the side surfaces of the gate body; anda PLC control device controls the gate extension oil cylinder, a first openness detecting device, a second openness detecting device, two displacement sensors, two limiting servo hydraulic oil cylinders, a gate flow calculating module, a flow monitoring module and a remote communication module. The dam gate is convenient to overturn with labor saving, and can be instantly locked; the gate body with any openness can be controlled to open; the gate flow calculating module can be used for timely calculating the openness of a hydraulic gate with specific flow; and better monitoring performances are achieved.

Description

technical field [0001] The invention relates to the technical field of water conservancy gates, in particular to an upturned dam gate capable of realizing instant self-locking control. Background technique [0002] Water conservancy gates are control facilities used to close and open drainage channels. An important part of hydraulic structures, it can be used to intercept water flow, control water level, adjust flow, discharge sediment and floating objects, etc. The current dam gate not only consumes a lot of energy, but also has many risks in manual decontamination, and the cost of maintenance is relatively high. At the same time, if the mud at the bottom of the gate cannot be removed in time, it will also have a certain impact on the safety of the entire dam. Therefore, it is urgent to design a water conservancy gate that is energy-saving, convenient, and timely decontamination. [0003] In water conservancy projects, the function of the gate is to open and close the gate...

AI Technical Summary

Problems solved by technology

[0007] The control systems and devices for the above-mentioned water conservancy gates are all for controlling the lifting gates, and most of the current gates are simple in structure and cannot realize remote control of the gates, which brings a lot of inconvenience to the control of the gates. At the same time, the current Due to the integrated structure of the gate itself, it restricts the opening of the gate
