Description

Technical Field

[0001] This invention belongs to the field of geological exploration technology, specifically relating to a tool for recording sandstone core samples from boreholes. Background Technology

[0002] In the current process of core logging for sandstone-type uranium deposits in northern China, geological technicians use auxiliary tools such as ordinary gem-identifying magnifying glasses, protractors, magnets, knives, and photographic scales. These magnifying glasses are only suitable for well-lit working environments, while the other miscellaneous auxiliary tools are small, have limited functions, and are not specifically designed for sandstone uranium prospecting geologists. They are inconvenient to carry and easily lost, thus hindering their use and impacting work efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a tool for recording sandstone borehole cores, which solves the problem of core observation in environments with insufficient light during geological logging. It is used to observe cores, measure the Mohs hardness, magnetism, and axial angle of cores, measure the length of objects with special phenomena, and can also be used as a photographic scale.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A sandstone core recording tool includes a first hard material body, a cylindrical magnetic rod, a knife, a second hard material body, a rotating shaft A, and a magnifying glass lens. The magnifying glass lens is installed in a magnifying glass mounting hole at the first end of the first hard material body. The second ends of the first hard material body, the cylindrical magnetic rod, the knife, and the second hard material body are hinged together by the rotating shaft A. The first ends of the first hard material body, the cylindrical magnetic rod, the knife, and the second hard material body can all rotate freely around the axis of the rotating shaft A.

[0006] An LED light group is provided on the corresponding hole of the first rigid material body located between the magnifying lens and the rotating shaft A.

[0007] The LED light assembly includes LED chips, reflectors, switches, and battery boxes. The LED chips, reflectors, switches, and battery boxes are respectively installed in corresponding mounting holes on the first rigid material body between the magnifying lens and the rotating shaft A.

[0008] The LEDs are installed below the reflector strip.

[0009] The switch and battery box are located on opposite sides of the first rigid material body.

[0010] The second end of the pointer is hinged to the second rigid material body via a pivot B, and the first end of the pointer can rotate freely around the axis of pivot B.

[0011] The front of the second hard material body is engraved with protractor scale lines.

[0012] The back of the second hard material body is engraved with scale lines.

[0013] Both the first and second hard material bodies are steel strip plate components, while the cylindrical magnet rod and the knife are hard material components.

[0014] A storage groove is provided between the front and back of the second hard material body. The first end of the first hard material body, the first end of the cylindrical magnet rod, the first end of the knife, and the first end of the second hard material body can all be rotated around the axis A and stored in the storage groove.

[0015] The beneficial effects achieved by this invention are as follows:

[0016] This invention features a compact and simple structure, is easy to use and carry. It can be used not only for observing rock cores but also for measuring core magnetism, Mohs hardness, and axial angle, preventing work disruptions due to lost tools. An LED light assembly facilitates core observation in low-light conditions. A protractor is used to measure the core axial angle during the recording process; a ruler is used to measure the length of objects exhibiting special phenomena, and also provides a standard unit scale for photography.
