Description

Technical Field

[0001] The utility model relates to the technical field of rock and soil exploration equipment, in particular to a water-proof and anti-fouling device for a probe of a drilling television imager. Background Art

[0002] In engineering geological survey, borehole TV imager is a very important survey equipment. It is mainly composed of borehole imager host, probe, depth counter, etc. Its working principle is that after the probe is placed in the hole, the hole wall is illuminated by the light source of the probe, and the digital camera captures the hole wall image reflected by the conical mirror. The image data is transmitted to the control host through the cable. After the image processing technology of the control host is deeply analyzed, it can be mapped 3 to 5 seconds after the start of acquisition. The generated image can truly and completely restore the electronic core map, and can form a digital borehole core for permanent preservation. It is particularly suitable for observing various characteristics and subtle structures of geological bodies in boreholes in engineering geological surveys, such as stratum lithology, rock structure, faults, cracks, interlayers, karst, etc., and compiling geological columnar maps.

[0003] At present, in the process of borehole television imaging, since the outer glass cover of the digital camera is easily in contact with the hole wall in the borehole, the water and mud attached to the hole wall will stick to the outside of the outer glass cover, resulting in the image collected by the probe being the water and mud on the outside of the glass. There is no way to truly and completely restore the electronic core map, which can form a digitized borehole core and easily miss various characteristics and subtle structures of the geological body.

[0004] Therefore, providing a device for preventing water pollution from the lens of a drilling television imager is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

The probe is not easy to touch the hole wall during the lowering process. At the same time, a super absorbent resin ring device is added at the connection position between the probe and the transmission line. The super absorbent resin (SAP) has strong water absorption and water retention properties, ensuring that rain and dirt on the upper part of the probe are absorbed by the super absorbent resin ring and will not flow down to the surface of the outer glass cover of the probe of the borehole television imager, ensuring that the outer glass cover remains in a relatively clean state during the lowering process of the probe, better realizing the function of borehole photography, ensuring that the collected data are complete and accurate, and improving the quality and efficiency of the collected data results.
