The working principle of the present invention is:

In the rectangular channel connecting the sea and the lake, a lock chamber is constructed. According to the different heights of the lock chamber, the upper and lower gates are set up. The lower one is a movable arc gate (which can rotate 180 degrees), and the upper one is a flat gate that can only move up and down. The left side of the lock chamber is the direction of connection with the lake (upstream), and the right side is the direction of connection with the sea. When the water in the lake needs to be discharged into the sea, the water flows from left to right, and the curved gate also rises from the tank under the action of the activation device. According to the different rotation angles of the arc gate around the rotating shaft, the different water retaining heights of the arc gate can be formed, which can better control the water level in the lake. When a higher water level is required, the arc gate can be directly operated to the flat gate position, and connected with the flat gate to form a correspondingly high gate. When the lake needs to release water, first open the flat gate to make it rise, and then run the arc gate into the sink after the water level drops. When excess salt is detected on the side close to the sea and seawater backflow may occur, the turning device of the arc gate is activated to rotate the arc gate counterclockwise from below to the side facing the sea to prevent seawater backflow.

One end of the rotating shaft 17 is arranged in the rotating shaft groove 18 in the inner wall space of the lock chamber 1 , and the rotating shaft 17 is rotatable.

The operation process of the arc gate is as follows: the engine 6 is started to drive the fixed pulley I7 through the steel chain 16, then the fixed pulley II8 is driven by the steel chain 16 through the fixed pulley I7, and the pulley 10 is driven by the steel chain 16 through the fixed pulley II8. , and then the pulley 10 drives the rotating shaft 17 to rotate in the rotating shaft groove 18 , and then drives the supporting hinge 9 to rotate, and finally drives the arc gate 2 to run.
