Gate inclination measurement and control system and measurement and control method

Abstract

The invention discloses a gate inclination measurement and control system. The system comprises a gate (1), gate grooves (2), gate opening-closing devices (3), a gate control circuit (4) and a computer remote monitoring system (5). The gate grooves (2) fit the gate (1), each gate opening-closing device comprises a steel wire rope (301) and a hoist (302), the gate is in transmission connection with each hoist through the corresponding steel wire rope, and the gate control circuit is in electrical connection with each hoist. The system further comprises horizontal measurement and control devices (6) and electrical circuits (7) of the horizontal measurement and control devices (6). The computer remote monitoring system comprises a first alarm signal lamp, a second alarm signal lamp and an alarm bell. The horizontal measurement and control devices are oppositely arranged on two sides of the upper end of the gate, and each electrical circuit (7) of the horizontal measurement and control devices (6) comprises an alarm circuit, a stopping circuit, a reset circuit, a power supply device (8) and an earth terminal. The gate inclination measurement and control system is adopted for monitoring gate inclination conditions, and alarming and effective control are realized before the gate is stuck.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a gate tilt measurement and control system and a measurement and control method. Background technique [0002] As water storage and drainage structures, gates play an increasingly important role in today's society. They play an important role in industrial and agricultural production, social and economic development, and also play an important role in river basin or urban flood control and drought relief. Plane gates and arc gates that are opened and closed by double-suspension hoist hoists are widely used in gates. The hoist hoist lifts and closes the gates by using the flexible transmission of wire ropes. During the operation of the gate hoist, due to reasons such as loosening and sliding of one side of the wire rope, excessive wear of the wire rope, the wire rope breaking away from the groove of the moving pulley, and foreign matter jamming on one side of...

AI Technical Summary

Problems solved by technology

During the operation of the gate hoist, due to reasons such as loosening and sliding of one side of the wire rope, excessive wear of the wire rope, the wire rope breaking away from the groove of the moving pulley, and foreign matter jamming on one side of the gate, the gate is tilted and stuck in the gate slot and cannot be lifted. If the operation is stopped in time, the motor of the hoist will be burned, the wire rope will be broken, the hoist or the gate will be deformed and damaged, and it will cause engineering operation accidents, especially when the gate is running at night, it is more difficult to find

[0003] At present, some water conservancy projects have enabled the computer remote monitoring system to control the opening height of the gate, which can remotely control the lift of the gate. However, when the gate is tilted, it does not have the function of prompting the gate to tilt, which makes it impossible to detect the tilt of the gate in time.

More importantly, there is no specific controllable device to observe whether the gate is tilted, and how to effectively control the gate before it gets stuck
