Abstract
The utility model relates to a continuous gyro inclinometer with minor diameter, which aims to solve the problems that the conventional inclinometer with low measuring accuracy can not achieve continuous measurement and the measurement inside a drill rod with the diameter of 73mm and a drill rod with the diameter of 89mm. The continuous gyro inclinometer has the major characteristics in that an electrical component (3), a gyro orienting device (5), an angle measuring device (6) and a righting device (7), which are connected through a cable and are arranged from top to bottom in sequence inside a protector tube component (4), and the outer diameter of the inclinometer is less than 50 mm. The continuous gyro inclinometer has the characteristics of continuous measurement and high measuring accuracy without lifting a drill.
Description
Technical field:
The utility model relates to geophysical exploration and the used a kind of instrument of subterranean well fields of measurement, the particularly a kind of minor diameter gyrolevel that can survey continuously.
Background technology:
Other shaft building engineering such as coal, metallurgy with freeze, during the special worker's methods construction of slip casting two, very high to the quality requirement of drilling of drilling well, geological environment complexity in addition is so require supporting with it measuring apparatus to have: the certainty of measurement of high reliability; The advanced person is method for continuous measuring fast; The applicability of particular surroundings; The instrument external diameter can be applied in Φ 73mm and the Φ 89mm drilling rod deviational survey less than Φ 50mm.The magnetic orientation inclinometer that generally uses in the past, anti-stratum magnetic interference ability is low, orientation error is big, the instrument external diameter is big, and be subjected to environment limit can not be in sleeve or drilling rod deviational survey, can only carry and bore the back and in naked hole, carry out a survey, can not continuous measurement, cause claim for eot, certainty of measurement is low, can not adapt to the requirement of present drilling engineering.
The utility model content:
Can not continuous measurement in order to overcome existing inclinometer, be subjected to the problem that measurement environment is limit and external diameter is bigger, the utility model provides a kind of minor diameter continuous inclinometer with the gyro principle orientation, this minor diameter gyro continuous inclinometer has continuous measurement under the situation of not carrying brill, certainty of measurement height, instrument external diameter less than Φ 50mm, can be applied to the characteristics of measuring in Φ 73mm and the Φ 89mm drilling rod.
Technical solution adopted in the utility model is: a kind of minor diameter gyro continuous inclinometer; comprise upper and lower centering pin and between the protection tube assembly; the protection tube component internal has electric component, gyrocompassing device, the angle-measuring equipment that is linked to each other by cable from top to bottom successively; the external diameter of control instrument is convenient to instrument application deviational survey in Φ 73mm and Φ 89mm drilling rod less than Φ 50mm.
The beneficial effects of the utility model are: owing to take such scheme, this inclinometer bearing unit adopts the gyrocompassing device, can not be subjected to the ground magnetic disturbance, improved certainty of measurement, and this gyro continuous inclinometer appearance and size is little, can put into drilling rod, can continuous measurement under the situation of not carrying brill, saving of work and time has improved operating efficiency and certainty of measurement greatly, has overcome the limitation of magnetic orientation device and defective that can not tie-in.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model, and wherein a is a left-half, and b is a right half part.
1-cable connector among the figure, the last centering of 2-pin, the 3-electric component, 4-protection tube assembly, 5-gyrocompassing device, 6-angle-measuring equipment, 7-be the centering pin down.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, a kind of gyro continuous inclinometer comprises upper and lower centering pin (2,7) and between protection tube assembly 4, cable connector 1, cable connector 1 connects goes up centering pin 2, upper and lower centering pin (2,7) all link to each other, and circumferentially can support, the effect of play centering, setting upright with spring; Protection tube assembly 4 inside have electric component 3, gyrocompassing device 5, the angle-measuring equipment 6 that is linked to each other by cable from top to bottom successively, and described gyrocompassing device 5 relies on gyrocompassing, can not be subjected to the ground magnetic disturbance, has improved orientation accuracy; In the described angle-measuring equipment 6 synchronized is arranged, can produce the signal of telecommunication synchronously, carry out continuous measurement with bore inclining; And this gyro continuous inclinometer appearance and size is little, adapts to measure in sleeve or drilling rod, need not carry boring and just can measure, and has improved operating efficiency and certainty of measurement greatly, has overcome the limitation of magnetic orientation device and defective that can not tie-in.
