Description

Technical Field

[0001] This utility model relates to the field of landslide monitoring technology, specifically a slope soil displacement monitoring and early warning device. Background Technology

[0002] When cracks appear on the surface of a landslide, it is necessary to monitor the displacement of the cracks in real time in order to better judge the development trend or to immediately sound an alarm when the cracks expand and a landslide or collapse is imminent, so that people in the surrounding area can take timely disaster avoidance measures.

[0003] Currently, in addition to manual monitoring via surveillance cameras deployed near landslides, more intelligent monitoring and early warning systems can be implemented using early warning devices. For example, Chinese utility model patent application number [application number missing] discloses a landslide monitoring and alarm device. When cracks on the slope expand, the distance between two positioning stakes increases, causing the fixed pulleys on the positioning stakes to rotate. This extends the measuring line between the positioning stakes, thereby moving the displacement monitoring and alarm device installed on the measuring line. When the displacement of the displacement monitoring and alarm device exceeds a preset value, the device issues an alarm, thus notifying surrounding personnel to take timely disaster avoidance measures. However, this device has significant drawbacks in actual use. The exposed measuring line can lead to inaccurate data due to external factors, such as plant branches blown by strong winds touching the measuring line, causing the measuring line to contract and become obstructed, resulting in distorted measurement data.

[0017] The function of the connecting pipe is to enable the connecting components to adapt to the connection requirements of the connecting pipe and different positioning piles, ensuring the reliability of the connection while meeting the corresponding active or fixed connection requirements.

[0018] In some embodiments, the connection assembly includes: a fixed connector and a rotating connector; One end of the connecting pipe 2 is fixedly connected to the positioning pile 1 located at a high elevation through a fixed connector, and the other end of the connecting pipe 2 is movably connected to the positioning pile 1 located at a low elevation through a rotating connector.

A limiting block is fitted inside the connecting pipe, with its bottom passing through a long groove at the bottom of the connecting pipe and fitting tightly against the outer wall of the connecting pipe. This fitting is then secured with locking devices to prevent the limiting block from moving inside the connecting pipe.

[0022] In some embodiments, the rotating connector includes: a connecting block 6, a support rod 7, and a stop block 8; The connecting block 6 is fixedly connected to the positioning pile 1 at the low-lying terrain.
