The probe is reasonable in design and simple in structure, convenient in debugging and free in maintenance after installation, and avoids the influence on the accurate measurement of the orientation and tilt due to an uncompleted eccentric block by utilizing the tilt sensor technology, thereby guaranteeing the accuracy of the measurement even the tilt of the borehole is less than 3 degrees.
Description
Technical field
The utility model relates to the geological survey instrument and meter, specifically a kind of borehole clinometer probe.
Background technology
At present, being used for the instrument of deviational survey on the geotechnical boring generally all is to adopt weighting block formula inclinometer, it is made up of probe and chart display, probe is that a framework is set in the inserting tube, the two ends of framework are provided with upper and lower thimble, framework is provided with weighting block, aspect sensor, obliquity sensor, and upper and lower thimble can make framework relatively rotation of sensitivity when inserting tube run-off the straight or orientation variation.It will be popped one's head in and slide to test point under drill hole wall during detection, when inserting tube tilts or orientation when changing the orientation, framework is deflected on certain predefined position, the azimuth that this moment, aspect sensor and obliquity sensor record and transmission were holed and the survey data at inclination angle.The certainty of measurement of inclinometer and weighting block be provided with very big relation, when inclination angle≤3 ° of boring, can influence weighting block framework is deflected into predefined position, at this moment measured data error is just bigger, when so existing weighting block formula inclinometer uses the inclination angle of boring necessary＞3 °, otherwise just can not guarantee the accurate of survey data.Upper and lower in addition thimble can strengthen its rotational resistance because of wearing and tearing, the sensitivity of framework rotation is descended, and framework is connected with lead with power supply, output interface, lead has contacted dark with framework can increase the frictional force that framework rotates, having contacted shallow then can influence output signal, thereby influences the certainty of measurement of instrument.
Summary of the invention
The purpose of this utility model is a kind of borehole clinometer probe that provides at the deficiencies in the prior art, it can also can guarantee the certainty of measurement at orientation and inclination angle when inclination angle＜3 ° of boring, further enlarged measurement category, and the signal transmission is unobstructed, reliable, the certainty of measurement height.
The purpose of this utility model is achieved in that a kind of borehole clinometer probe, comprise two joints that sleeve pipe and sleeve pipe two ends are threaded, characteristics are that upper/lower terminal is respectively equipped with fixed mount, gage frame in the sleeve pipe, fixed mount is provided with output/input interface, power supply, control circuit, stepper motor, and gage frame is provided with obliquity sensor, aspect sensor, two ends and is provided with rotating shaft; One joint is provided with bearing support; The inwall of fixed mount and sleeve pipe is affixed, and an end of gage frame is supported on the bearing support by rotating shaft, and other end rotating shaft is connected with stepper motor by shaft coupling.
Suit collecting ring in the described rotating shaft, the coil holder on the collecting ring are then affixed with the inwall of sleeve pipe.
Described output/input interface, power supply, control circuit, stepper motor, collecting ring, coil holder, obliquity sensor, aspect sensor are connected by lead respectively.
The utility model is reasonable in design, simple in structure, it adopts the inclination angle sensing technology, has avoided influencing owing to weighting block is not in place the accurate measurement at orientation and inclination angle, has further enlarged measurement category, during inclination angle＜3 ° that make boring, also can guarantee the accurate measurement at orientation and inclination angle, and the signal transmission is unobstructed, reliable, the certainty of measurement height, debugging is convenient, and fault rate is low.
