A monitoring, alarm, and early warning device for weak geological areas of slopes at construction sites.

Abstract

This utility model discloses a monitoring and alarm early warning device for weak geological areas of slopes at construction sites, relating to the field of slope monitoring technology. The utility model includes a support column, with an adjustment box fixedly connected to the top of the support column. A universal joint is fixedly connected to the adjustment box, and a level plate is fixedly connected to the top of the universal joint. A monitoring device is mounted on the top of the level plate. A lifting mechanism is provided inside the adjustment box, including a first threaded rod rotatably connected to the inner wall of the adjustment box via a bearing seat. This utility model achieves three-dimensional independent fine-tuning of the level plate by alternately meshing three height-displaced second gears in the leveling mechanism with the first gear driven by the lifting mechanism, combined with real-time feedback from the level instrument. The universal joint structure ensures flexible and stable leveling, keeping the monitoring device always horizontal, thus avoiding data distortion caused by base inclination.
