Description

Anti-drop self-locking type intelligent marking nail Technical Field The utility model relates to the technical field of stratum marking, in particular to an anti-falling self-locking intelligent marking nail. Background In the field of field geological work, the marking nails are key tools for geological exploration, stratum marking and other works and are used for marking geological points, recording stratum information and the like. The structure of the traditional marking nail is usually a straight rod type or a winged type, and is mainly fixed in soil or rock body by hammering and the like so as to realize the marking function. However, there are some problems in the prior art that need to be solved. The traditional straight rod type marking nail has a simple structure and is mainly kept fixed by virtue of friction force between the nail body and the soil body. In some complex geological environments, such as soft soil or rock mass with a certain degree of weathering, such marking nails are prone to fall off due to loosening of the soil, resulting in marking failure. Although the contact area between the wing-type marking nails and the soil body is increased to a certain extent, the anti-pulling force is improved, the wing-type marking nails are easy to cause larger disturbance to the soil body in the hammering process, the original structure of the soil body is damaged, and the marking accuracy is affected. Meanwhile, the traditional marking nails have single functions in the aspect of information recording, and can not realize automatic storage and reading of information only by manually recording marking positions and related information, so that the working efficiency is greatly reduced in large-scale geological exploration. In addition, the color and code marks of the traditional marking nails have poor visibility in environments with insufficient light (such as holes or nights), so that a plurality of inconveniences are brought to the recognition and recording work of on-site staff, and the continuity and accuracy of geological work are affected.
