置。[Scope of Claim for Utility Model Registration] A device for detecting the passage of a ship through a lock, comprising: a ship detection sensor that detects a ship in the lock; and a passage determination section that determines whether a ship has passed based on the output of the ship detection sensor. an altitude adjustment unit that adjusts the detection target altitude of this ship detection sensor based on an altitude instruction; a water level detection sensor that detects the water level in the lock room; and an altitude control unit that follows changes in water level based on the output of this water level detection sensor. A ship passage detection device for a lock, comprising: an altitude indicator outputting an altitude instruction.
