Drilling radar detector in-hole centering device

Abstract

The invention relates to a drilling radar detector in-hole centering device which comprises a mounting frame, a conical barrel, a rubber barrel, a first connecting rod, a second connecting rod, a semicircular shell, a roller, a first spring, a first torsion spring, a driving mechanism and a guide mechanism. The conical barrel is fixedly connected among the four sides in the mounting frame; the guide mechanism is mounted in the circumferential direction of the outer side of the conical barrel; and the driving mechanism is mounted between the two sides of the mounting frame. According to the invention, a drilling radar is placed in the rubber barrel to be clamped, the drilling radar corresponds to a hole entrance, the driving mechanism is started, the driving mechanism does not limit the rubber barrel, the rubber barrel drives the drilling radar to move downwards into a hole under the action of gravity, and the roller is in contact with the inner wall of the hole to guide the rubber barrel, i.e., the drilling radar is guided, so that the influence of swing of the drilling radar on a detection result can be avoided, and the drilling radar cannot be in contact with the inner wall of the hole to cause abrasion.

Description

technical field [0001] The invention relates to a centering device, in particular to a hole-entry centering device for a borehole radar detector. Background technique [0002] In national defense projects, in order to detect the situation in the cave, it is necessary to use the borehole radar to image the cave, so that people can understand the situation. At present, when the borehole radar enters the cave, the borehole radar is easy to swing with the inner wall of the cave. Contact will lead to deviations in the detection results, and there are many impurities on the inner wall of the hole. Direct contact with the drilling radar is likely to cause wear. [0003] Therefore, it is necessary to design and develop a hole-entry centering device for the hole radar detector that can keep the hole radar in the middle position, is not easy to swing to affect the detection results, and is not easy to touch the inner wall of the hole to cause wear.

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the shortcomings that the drilling radar is easy to swing and contact with the inner wall of the hole, resulting in deviation of the detection results, and the inner wall of the hole is more impurity, and the direct contact of the drilling radar is easy to cause wear and tear. The technical problem to be solved is: to provide a The hole-entry centering device of the hole radar detector is not easy to swing and affect the detection results, and is not easy to touch the inner wall of the hole to cause wear and tear so that the hole radar is in the middle position.
