DEVICE FOR INSPECTION OF HYDRAULIC STRUCTURES Russian patent published in 2022 - IPC G01S15/00 

FIELD: underwater technology.

SUBSTANCE: invention relates to the field of underwater technology used for the survey, maintenance and periodic inspection of the surfaces of hydraulic structures, namely, remote-controlled underwater robotic systems that provide high-precision survey, including the use of non-destructive testing methods, profiling underwater extended and located in the zone of variable water level object surfaces. The device for inspection of hydraulic structures additionally contains a unit for ultrasonic testing of structural strength, a unit for monitoring angular values, a video camera, an ultrasonic underwater thickness gauge, a unit for underwater measurement of electrode potentials, a navigation instrument assembly placed on a movable carrier, as well as a compass connected to the unit for recording readings, an inclinometer , connected to the readings recording unit, stopwatch connected to the readings recording unit, depth gauge connected to the readings recording unit; a video data storage module placed on a floating buoy, connected to the output of the control unit, designed to store video files of a video camera; at the same time, the cable line is additionally equipped with an adjustable electric drive placed on a floating buoy and connected to the output by a control unit.

EFFECT: increasing the reliability of determining the technical condition of building structures of hydraulic structures of various functional purposes based on monitoring physical parameters and adding new functional options - ultrasonic strength control of building structures, determining deviations between structures and measuring gaps between structures of hydraulic structures, determining the thickness of metal structures under water, determining electrode corrosion potential of metal structures, survey of the bottom of water areas.
