[0002] Geological exploration refers to a series of technical work and research activities carried out to find out the distribution, quality, quantity and development and utilization conditions of underground resources. It mainly includes mineral geological exploration, oil and gas geological exploration, hydrogeological exploration, engineering geological exploration and environmental geological exploration. The purpose of geological exploration is to find and evaluate underground resources, such as minerals, rocks, groundwater, oil and gas, and provide a scientific basis for the development, utilization and protection of resources. Anti-collapse devices are usually used in geological exploration to prevent the collapse of the opened channels;

[0003] Anti-collapse devices are usually composed of components such as load-bearing columns and support plates. They are mainly used to protect boreholes and wellbores from collapsing due to changes in well wall pressure, ensuring the safety of exploration and mining work. However, some existing anti-collapse devices still have some problems.

[0004] 1. Some anti-collapse devices have a limited height adjustment range and cannot adapt to all well walls, especially when encountering special well walls, such as soft and hard interlayers and high-pressure formations, resulting in unsatisfactory anti-collapse effects.

[0005] 2. During geological exploration, the well wall is usually affected by gravity and sinks slowly to a small extent, requiring real-time monitoring by staff, which is inconvenient. Utility Model Content

[0017] 2. The utility model provides the limit plate, locking plate, support spring, push-type alarm and trigger rod and other components. When the top of the well wall sinks, the well wall squeezes the arched top plate, and the arched top plate transmits the pressure to the two support plates. The two support plates descend with the pressure. In the process of the support plate descending, the support plate can squeeze multiple support springs. When the support plate descends to a certain depth, the support plate drives the trigger rod to squeeze the push-type alarm, thereby promptly reminding the staff that the well wall is sinking. The staff can carry out maintenance in time to avoid the collapse of the well wall. BRIEF DESCRIPTION OF THE DRAWINGS
