Intelligent hydraulic flood gate and control system thereof

Abstract

The invention discloses an intelligent hydraulic flood gate and a control system thereof. The system comprises a human-computer interface touch screen, an operation fault monitoring indicating lamp, an ultrasonic water level sensor, a radar current meter, a pull rope displacement sensor and an intermediate relay which are all connected with a PLC. The intermediate relay is also connected with thehydraulic hoist; the hydraulic hoist is connected with the flood gate; compared with the prior art, according to the invention, the flood gate can be hierarchically controlled according to the upstream actual monitoring water level and the downstream flood discharge actual monitoring water flow rate; the opening height and state of the flood gate can be intelligently adjusted in real time; monitoring data and fault information are displayed in time, frequent coming and going to a gate site and a central control room are not needed, the labor intensity of workers is effectively reduced, the working efficiency of the system is improved, the intelligent remote control purpose is achieved, the burden of the workers is greatly relieved, dangerous cases can be handled in time, and flood controlwork is safely and effectively conducted.

Description

Technical field: [0001] The invention belongs to the technical field of intelligent electromechanical control, in particular to an intelligent hydraulic flood control gate and its control system. Background technique: [0002] The traditional hydraulic hoist uses the simple start control cabinet to control the motor and solenoid valve of the hydraulic system to realize the opening and closing of the oil cylinder, thereby driving the opening and closing of the gate. There is a certain distance between the flood control gate and the control room. If the flood gate cannot be opened in time to discharge the flood and waterlogging in case of a flood, the harm and danger caused will be immeasurable. Even when the control room opens the flood control gate, it is impossible to judge the opening degree of the gate. It is necessary to check the site with the naked eye. Frequent travel between the gate site and the central control room is not conducive to timely handling of dangerous s...

Problems solved by technology

There is a certain distance between the flood control gate and the control room. If the flood gate cannot be opened in time to discharge the flood and waterlogging in case of a flood, the damage and danger caused will be immeasurable.

Even when the control room opens the flood control gate, it is impossible to judge the opening degree of the gate. It is necessary to check the site with the naked eye. Frequent travel between the gate site and the central control room is not conducive to timely handling of dangerous situations, and the opening degree of the gate is mostly estimated by the actual experience of the staff. It is impossible to make accurate judgments based on the actual water level upstream, nor can it adjust the opening height and status of the flood gates in a timely manner based on the actual water flow rate of the downstream flood discharge. Monitoring data and fault information cannot be obtained in time, even if the labor of the staff is increased. Intensity, can not effectively improve work efficiency, not only increases the burden on staff, but also does not deal with dangers in time, can not make flood control work safe and effective
