AI Technical Summary

Technical Problem

In existing borehole detection, the lowering of borehole imaging instruments can easily cause loose soil to fall off the borehole wall, and sand and dust can obstruct the lens's field of view, affecting the accuracy of imaging and recognition. Furthermore, the lack of standardization in borehole data leads to chaotic stratigraphic division.

Method used

A standardized classification and detection device for boreholes was designed, comprising a support, a detector, a fisheye lens, a limiting mechanism, an auxiliary mechanism, and a reset mechanism. By setting a blocking plate and a rotating component, fine sand and gravel are prevented from obstructing the lens, and an artificial neural network model is used to standardize and classify borehole data.

Benefits of technology

It effectively reduces the impact of fine sand and gravel on the fisheye lens, improves the imaging accuracy of the borehole inner wall and the efficiency of data standardization processing, ensures the smooth lowering of the borehole imaging instrument, and supports the accuracy of 3D geological modeling.

Abstract

This invention relates to the field of exploration hole detection equipment technology, and discloses a standardized classification and detection device and method for exploration holes. The device includes a support, with a detector fixedly connected to the side wall of the support. A reel is fixedly connected to the output end of the detector. Addressing the problem of fine sand and gravel obstructing the fisheye lens during lowering, the device incorporates a limiting mechanism and an auxiliary mechanism. Under normal conditions, because the blocking plate blocks the inner wall of through-hole one, and through-holes two and three overlap, the connecting pipe can extract air from the bottom of the fisheye lens through the connector, extraction pipe, and flow assembly. When the fisheye lens approaches the inner wall of the exploration hole, the exploration hole pushes the arc-shaped contact block towards the auxiliary assembly, creating a gap between the blocking plate and through-hole one. At this time, the extraction force of the connecting pipe is transmitted through the gap to the contact position, extracting any fine sand and gravel falling at the contact position, effectively reducing the impact of falling fine sand and gravel on the fisheye lens.
