MEASURES OF PROTECTION OF LOCK GATE FROM DOCKING IMPACTS Russian patent published in 2008 - IPC E02B7/20 E02C1/10 

FIELD: construction.

SUBSTANCE: measures of protection of a lock gate from docking impacts involve formation of a head wave in the lock chamber. The head wave stops a vessel before the lock gate. In order to form a head wave, tanks with water are put in the lock head and connected to the lock chamber with water conduits equipped with fast drop water feed sluices with stoppers. The lock walls have the sensors installed that register the speed of a vessel. If a design speed rises in the lock chamber, the sensors send a signal to the gears of the stoppers of the water feed sluices, which release the gates ensuring they fall into the lock recess and open the water conduits. Then the water instantly comes into the lock chamber making a wave moving towards the vessel. In order to protect the gate from impacts of the vessels coming from the tailrace canal, flush is used from the headrace canal or the upstream chamber. For this purpose, water conduits with fast drop water feed sluices are installed in the lock head. Current culverts of filling and emptying of sluices are used for fast flushes causing a wave, and, with this object in view, the working sluices in the culverts will be re-equipped with a fast open system.

EFFECT: enhanced reliability of protection of the lock gate from docking impacts.
