DEVICE FOR MEASURING SHIP DRAFT IN SEA MOTIONS Russian patent published in 2018 - IPC B63B39/12 

FIELD: shipbuilding.

SUBSTANCE: invention relates to the field of shipbuilding and concerns the issue of creating technical means for controlling the draft of the ship in waves and in calm water both in drift and on the move, including emergency situations. Device is proposed for measuring the draft of a floating device, comprising two differential pressure transmitters located on the same normal to the main plane (MP) operating simultaneously, the positive inputs of which are connected to the main straight pipe communicating with the water seaward space with direct pipes and their negative inputs are connected with the atmosphere by the other pipeline, the calculator. Additional straight pipe of the same cross-section with the main pipeline is introduced, coaxial to it and communicated by the lower part with the upper part of the main pipeline, upper part of the additional pipeline is communicated with the atmosphere and is above the maximum instantaneous value of the precipitate. Longitudinal axis of the main pipeline and the longitudinal axis of the nozzles are in the DP or in one of the planes parallel to it, in which this normal is located. Longitudinal axes of the branch pipes are located at the angle, the value of which is less than the difference between the right angle and the module of the maximum instantaneous value of the trim angle, to the longitudinal axis of the main pipeline. Upper parts of the nozzles are below the minimum instantaneous value of the draft. Projection of the receiving aperture in the bottom on the MP and the projection of the main pipeline onto this plane coincide.

EFFECT: technical result consists in increasing the accuracy and reliability of the operation of the precipitation gauge, simplifying its operation, expanding the possibilities for use in waves and calm water.
