Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a structure for the head gate of a ship lift lock. Background Technology

[0002] As a navigation facility, ship lifts are mainly used for the vertical and rapid passage of inland waterway vessels through dams. Existing vertical ship lifts connect upstream and downstream by having the ship compartment dock with the upstream and downstream lock gates, utilizing docking sealing frames and a water filling / draining system to connect the docking channels. Therefore, the design of the lock gate of the ship lift plays a crucial role in the entire ship lift system.

[0003] CN118932963A discloses a water-blocking device and method for lock heads in ship lift channels where water levels change rapidly. The device includes a working gate, a maintenance gate, a working gate slot, and a maintenance gate slot. The working gate includes a large working gate, which is placed within the working gate slot and raised and lowered by a lifting device. Locking devices are arranged on the left and right sides of the working gate, and multiple sets of water-blocking locking slots are arranged at intervals along the height direction on the corresponding working gate slots. The locking devices lock or unlock with the corresponding water-blocking locking slots. This patent does not disclose the specific structure of the lock head gate of a ship lift.

[0004] CN118854878A proposes a method for water-blocking at the lock head of a ship lift when the water level in the channel drops. The method includes the following steps: when the water level drops, determine to reduce one section of the working gate; raise the maintenance gate to the maintenance gate slot to block water; drain some water between the working gate and the maintenance gate; raise the working gate to its support pier; raise one section of the working gate and lower it to its support pier; raise the working gate and lower it to its slot; raise the maintenance gate, allowing channel water to fill the space between the working gate and the maintenance gate; raise one section of the maintenance gate and lower it to its support pier; and tighten the maintenance gate using a gate hoist. However, this method suffers from insufficient flexibility in the water-blocking structure when reducing one section of the working gate for lock head water blocking. Utility Model Content
