Automatic on-off for arc gate

Abstract

The present invention discloses a curved gate automatic switch. It includes water storage cavity, frame, pulley, gate, steel rope and automatic contraction device connected with steel rope. On the frame, a jack horizontal starting switch is set, the inner side of said gate is equipped with an operation door. It is characterized by that on the frame a lever starting machine and a gear are set, said lever starting machine is connected with gate by means of steel rope, on the operation door of inner side of said gate a multi-bar mechanism is mounted, and said multi-bar mechanism is connected with steel rope and automatic contraction device. Said invention also provides the working principle of said curved gate automatic switch and its concrete operation method. Said invention can attain the goal of automatically and safely discharging flood.

Description

technical field [0001] The invention relates to the field of gates, in particular to an automatic switch for an arc gate. Background technique [0002] Nowadays, plane gates and arc gates are commonly used in sluice gates. Due to the influence of water head and water pressure, the gate opening force and frictional resistance of plane gates are very different, and super-high dam surface hoisting platforms and relatively high gates are required. Thick gate piers and other defects, arc gates have small frictional resistance affected by water pressure, open and close flexibly start their own weight, and do not need to set gate slots, which are widely used in large gate projects, ahead of traditional gates, but There are defects such as super long and super high support arms and hinges, unbalanced foundation force points, inability to use energy, gravity, high-altitude operation of dam rocks, and effortless opening and closing of gate switches. In order to save energy and power,...

[0002] Nowadays, plane gates and arc gates are commonly used in sluice gates. Due to the influence of water head and water pressure, the gate opening force and frictional resistance of plane gates are very different, and super-high dam surface hoisting platforms and relatively high gates are required. Thick gate piers and other defects, arc gates have small frictional resistance affected by water pressure, open and close flexibly start their own weight, and do not need to set gate slots, which are widely used in large gate projects, ahead of traditional gates, but There are defects such as super long and super high support arms and hinges, unbalanced foundation force points, inability to use energy, gravity, high-altitude operation of dam rocks, and effortless opening and closing of gate switches, etc.

In order to save energy and power, people have improved the connection structure of the gate, such as the traditional hydraulic impact automatic flap gate, which can coordinate the size of the flood flow and automatically switch the flood discharge. The poles are lying in the torrent, which will inevitably damage the gate due to hydraulic impact, and it is easy to be washed away by the flood. Moreover, after the flood, it is inevitable that debris will block various parts such as the outriggers, forcing the gate to fail to reset. Power and manual pull

In addition, since the design of this gate should not be wide, it is only suitable for low water level irrigation, and the practical range is small.
