DEVICE FOR MEASUREMENT OF CHANNEL DEFORMATIONS Russian patent published in 2019 - IPC F17D5/06 F16L1/16 

FIELD: physics.

SUBSTANCE: invention relates to telecommunication devices for remote monitoring, telemetry and can be used in monitoring underwater transitions of main pipelines and communication lines. Device includes a radioparent housing with positive buoyancy. In one part of the housing by means of strong fastening structures a printed unit (PU) is installed with the microcircuits of controller, modem, their strapping and antennae placed on it. Printed unit (PU) is connected through a position sensor to the key for closing the supply circuit with the power supply source when the position changes relative to the initial one at surfacing. In opposite part of housing there is a load-counterweight. Power supply unit can be presented in the form of a load-counterweight. Besides, in order to simplify the design, the printed unit can be presented in the form of a mobile telephone, in the circuit of which the position sensor is connected from the accumulator with a key for closing the supply circuit when the position changes relative to the initial one. Each device has a unique identification number (ID), which is automatically transmitted by the device when surfacing into the network when it is detected. Fact of surfacing and detection by a network of a specific device signals about channel deformation (wash-out of channel) at the corresponding depth in the corresponding place.

EFFECT: use of proposed devices makes it possible to automate and reduce the cost of channel deformation monitoring process in areas of underwater crossings of main pipelines and communication communication lines.
