INCLINOMETER Russian patent published in 1998 - IPC

FIELD: instruments for checking bore-holes. SUBSTANCE: inclinometer is used for determining spatial position of bore-hole. Inclinometer has sensor of azimuth and zenith angles, clockwork, and detent unit with spring-biased rod. Included in it are digital disk of time setting, and pair of cams which have shaped slots oriented relative to each other for interaction with pin which is located in one end of sectional spring-biased lever. Other end of spring-biased sectional lever interacts with pins which are located in end face of one of shaped cams which is rigidly secured on axle together with handle and other shaped cam. Profiles of both shaped cams are in contact with spring-biased output shaft of sensor of azimuth and zenith angles. Aforesaid embodiment of inclinometer gives high accuracy of indications and operates reliably in determining spatial position of bore-holes of any type. EFFECT: higher efficiency. 1 dwg
