TRAWL FOR FINDING UNDERWATER OBSTACLES Russian patent published in 2009 - IPC B63C11/48 G01C13/00 

FIELD: shipbuilding.

SUBSTANCE: invention relates to hydrographic trawls for finding underwater obstacles. Trawl for finding underwater obstacles contains a sweeping beam, connected with a haulage line and lifting-signal rope, support beam, mechanism of manoeuvring the lifting-signal rope, guiding elements for the lifting-signal rope, indicator of the depth of the deposit of the obstacle with scales. Depth markers of the deposition of the obstacles are made in the form of a balance beam, pivotally fixed to the support beam. One of the ends of each balance beam is linked with the corresponding scale, arresting device for the balance beam, on which is mounted a contact sensor trawl is equipped with a device for determining coordinates of the water craft and personal computer, connected with the contact sensor and the device for determining coordinates of the water craft.

EFFECT: increase in the accuracy of determining the depth of the deposits of obstacles, reliability of the device, precision in determining the coordinates of the location of the underwater obstacle, also simplification of reinstallation of the device from one water craft to another.
