introduction
The lock is a box-shaped navigation building that utilizes irrigation and discharge of water in the channel controlled by gates at both ends to raise and lower the water level so that the ship can overcome the concentration drop of the water level on the navigation channel. The shiplock consists of a gate, a lock chamber, a water delivery system, a gate, a valve, a pilot channel, and corresponding equipment. The ship lock shall be equipped with a special water filling and discharging system and a device for controlling the gate.
Control gates are sluice gates that regulate the upstream water level and control the discharge flow, and are generally open. The control gate of the channel uses the opening and closing of the gate to adjust the upstream water level and discharge flow to meet the needs of the next level channel to divide water or control and cut off the flow. The composition, structure and design points of the control gate are the same as those of the general sluice.
