Taking a vertical ship lift as an example, a procedure for a ship to pass through the ship lift will be described. If the ship runs upstream, firstly the ship receiving chamber stops at the lower lock head, the ship enters the ship chamber from the downstream channel, then the lock head and the lock chamber gate are closed, gap water between the chamber head gate and the lock head working gate is drained, under the action of the driving device, the ship receiving chamber immediately rises and stops at the upper lock head, after the ship receiving chamber and the upper lock head are tensioned, sealed and filled with the gap water, the ship chamber and the lock head gate are opened, and the ship immediately runs into the upstream channel. Waiting for a descending ship to enter a ship receiving chamber along with the descending ship, and sequentially carrying out reverse operation of the procedures, wherein the ship can enter a downstream channel from an upstream channel, and when the ship ascends, the ship enters the ship receiving chamber from the downstream channel, after closing a gate and a downstream end chamber door, draining water in a gap between the two doors, loosening tensioning and sealing devices of the ship receiving chamber and a lower lock head, and lifting the ship receiving chamber and stopping at a position in butt joint with an upper lock head under the action of a driving device; loosening the tensioning and sealing device between the ship reception chamber and the upper lock head, and filling water into the gap between the gates; and (4) opening the working gate of the upper lock head and the cabin door at the upstream end of the ship receiving cabin, so that the ship can enter the upstream navigation channel. When the ship lift goes down, the requirements of the ship lift on the water level and the sediment quantity of a river channel are high, and therefore real-time detection and early warning on the water flow and the sediment quantity of the river channel are needed to ensure the normal work of the ship lift.
