DEVICE TO INVESTIGATE GEOMETRIC IMPERFECTIONS OF RESERVOIRS BY MOIRE METHOD WITH TWO SUPPORTS Russian patent published in 2014 - IPC G01B11/25 

FIELD: measurement equipment.

SUBSTANCE: invention relates to the group of instrumentation, namely, it is a device for definition of initial geometric imperfections of a wall of cylindrical reservoirs (indents, cracks, ovalities, etc.). The device comprises a lifting-lowering and rotating mechanism of a platform, which includes upper and lower fixators, a pipe with a movable platform fixed to it. On the platform there is a camera and a projector. The platform is rotated by means of a step electric motor fixed inside the lower fixator. Lifting-lowering of the platform is carried out with the step electric motor fixed on the pipe and a belt, rope or chain mechanisms. The camera is rotated to adjust the device with the help of a step electric motor. Power supply to the camera, projector, electric motor for rotation of the camera, electric motor for rotation of the platform, electric motor for lifting-lowering of the platform is provided by means of a power cable laid inside the pipe. Control of step electric motors, projector and camera is carried out by means of a controller that receives signals via a modem communication line from a computer.

EFFECT: increased accuracy of measurement of geometric imperfections of cylindrical reservoirs.
