Claims

[Scope of utility model registration request]

An ultrasonic transducer 3 installed on an underwater working machine 1 placed in a working area to measure the depth of water from the working machine 1 to the crystal; , and the ultrasonic transducer 16 whose height is set to the construction plan reference plane B, which is set to a depth H2 from the reference plane A, and the time signal sent from these ultrasonic receivers 3 and 16. Means for calculating the average water depth h□9 h2 from a plurality of water depth data htt h2 over time, and these average water depths hl? A means of calculating the height ΔH from the construction plan reference water surface B to the underwater working machine 1 from the difference of π2, and calculating the water depth H1 from the reference surface A to the underwater working machine from the height ΔH and the above setting source height H2. A leveling device for an underwater working machine comprising:
