Abstract
The invention discloses a declinator probe for boring, which includes a bushing and two joints connected at the two ends of the bushing by screw thread. The probe is characterized in that the upper and lower ends in the bushing are respectively provided with a fixing frame and a measuring frame. The fixing frame is provided with an input-output interface, a power supply, a control circuit and a stepper motor. The measuring frame is provided with an obliquity sensor and an orientation sensor; the two ends of the measuring frame are provided with rotary shafts; one joint is provided with a bearing seat; the fixing frame is fixedly connected with the inner wall of the bushing; one end of the measuring frame is supported on the bearing seat by the rotary shaft; the rotary shaft arranged at the other end is connected with the stepper motor through a shaft joint. The invention has reasonable design and simple structure. The declinator probe adopts the technology of obliquity sensing which avoids the accurate measuring of the orientation and obliquity being affected caused by that an imbalance block is not in place, thus ensuring the precision of measuring with the advantages of convenient debugging and being free from maintenance after installation when the obliquity of boring is smaller than 3 degrees.
Description
Technical field
The present invention 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
A kind of borehole clinometer probe of providing at the deficiencies in the prior art is provided, 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 object of the present invention is achieved like this: 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 present invention 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.
