[0002] Landslide refers to the natural phenomenon of loosening, flowing or collapsing of soil and rocks on the surface or rock slopes. Landslide disasters often cause serious damage to people's lives, property and the environment. Therefore, it is very important to monitor and warn of landslides. The landslide online monitoring and early warning device is a device specially used for real-time monitoring and early warning of landslides. It can measure surface displacement, inclination angle, groundwater level, groundwater pressure, seismic activity and other indicators through a variety of sensors and monitoring instruments, and use the data collected by the sensors to analyze the development trend and risk level of the landslide in real time.

[0003] A Chinese patent document with the publication number CN218729328U is retrieved and disclosed, which is an online monitoring and early warning device for landslides. The device comprises a GNSS antenna, a suction cup antenna, an anti-interference outer shell, a detector, an upper base plate, a lower base plate, an adjustable stiffener, a column and a conical support foot. The GNSS antenna and the suction cup antenna are positioned and installed on the horizontal surface of the anti-interference outer shell. The adjustable stiffener is installed on the inner diameter of the column and fixedly connected with the lower base plate. The column and the conical support foot are welded and installed as one piece. An online monitoring and early warning device for landslides is designed and suitable for the positioning and installation of the online monitoring and early warning device for landslides. The adjustable stiffener is welded and installed on the lower end of the turntable. The bottom end of the stiffener is positioned and installed with a bottom bearing. The turntable is rotated manually, and the threaded rod is threadedly butt-jointed with the threaded mounting sleeve, thereby realizing the structural butt-jointed installation of the adjustable stiffener and the lower base plate, and ensuring the stable installation of the entire device.

[0004] However, when the above device is in use, it is fixed by means of conical supporting feet. However, due to the complex geographical environment of mountainous areas, there is a possibility that the device may be placed unstable or fall over, which may affect the use of the device and there is a risk of damage to the device.

[0037] Reference Figure 5 The angle adjustment component includes an articulated frame 203 , the bottom end of the articulated frame 203 is fixedly connected to the top end of the fixed arm 204 , and the fixed arm 204 can be rotated through the articulated frame 203 .

[0038] Reference Figure 4 The disassembly mechanism 1 includes a column 101, and a limiting ball 103 is engaged with the outer side of the bottom end of the column 101. The column 101 is engaged with the limiting ball 103, so that the column 101 can be fixed.

[0039] Reference Figure 4 A snap ring 104 is slidably connected to the outer side of the limiting ball 103 , and a spring 107 is fixedly connected to the lower end of the snap ring 104 , and the snap ring 104 is supported by the spring 107 .
