Description

Technical Field

[0001] The invention relates to the technical field of environmental monitoring, in particular to a device for monitoring karst geological environment. Background Art

[0002] Karst geology is a geological landscape formed by karstification. According to the location of karstification, it can be divided into surface karst landscape and underground karst landscape. The surface karst landscape is a series of phenomena formed by surface water along the surface of soluble carbonate rocks. The underground karst landscape is composed of underground cavities formed by groundwater dissolving along the cracks of soluble carbonate rocks.

[0003] With the increasing role of human activities such as the development of land resources, water resources and mineral resources in karst areas and engineering construction, the resulting karst collapse disasters occur frequently, causing increasing losses. It has become the main geological disaster in karst cities, seriously hindering urban economic construction and development. Therefore, monitoring devices are needed to monitor the geological environment in real time.

[0004] The existing device mainly fixes the geological radar in the karst geological environment for real-time monitoring through a fixing component. The structure with patent number CN109188539A includes a geological radar, the bottom end of the geological radar is screwed to a supporting component, the left and right sides of the supporting component are clamped with one side of the tightening mechanism, and the other side of the tightening mechanism is welded with a cross plate, and the top of the cross plate is plugged with a conical column. This invention can ensure that the geological radar can remain horizontal even if it is installed on an uneven ground or the ground becomes uneven after settlement. The supporting components supporting the geological radar can be tightened as the ground in the karst area settles to avoid the deviation of the geological radar. The overall stability is good and the use is flexible, which improves the stability and safety during monitoring. However, there are still areas that can be optimized in the device.

[0005] The existing devices mainly anchor the geological radar through multiple groups of anchor rods, chains and other structures, so that some devices need to manually anchor multiple groups of fixing components in sequence to fix the geological radar, which makes the fixing operation of some devices more cumbersome. Secondly, some devices are restricted by multiple groups of fixing components, so that some devices adjust the bottom of the geological radar to fit on the ground, resulting in a waste of a lot of installation and deployment time. Finally, some devices mainly fix the geological radar inside the placement box, making it difficult for some devices to quickly load and unload the geological radar for maintenance and replacement, resulting in a waste of a lot of maintenance time and reducing the work efficiency and practicality of the device. Therefore, in order to solve the above problems, a device for karst geological environment monitoring is proposed. Summary of the invention
