Abstract
Description
Technical Field
[0001] This utility model relates to the field of landslide monitoring and early warning technology, specifically a multi-layer sliding surface landslide monitoring and early warning device. Background Technology
[0002] In the field of geological disaster monitoring, landslides pose a significant threat due to their complexity and frequent occurrence. Existing landslide monitoring devices are mostly designed for single sliding surfaces, which are difficult to effectively cope with the complex conditions of multi-layered sliding surface landslides. They have shortcomings such as single monitoring dimensions, insufficient real-time performance, and low early warning accuracy, and cannot meet the precise monitoring needs of dynamic changes in multi-layered sliding surfaces. There is an urgent need to develop new early warning devices with multi-layered monitoring capabilities to improve the level of disaster prevention and control.
[0003] Existing devices suffer from inefficient driving methods and difficulty in penetrating deep into the soil; limited monitoring dimensions, making it impossible to perceive multi-layered sliding surfaces in real time; rudimentary protective structures, leaving sensors susceptible to damage from soil particles, gravel, and water accumulation; lack of effective mechanical collision protection, resulting in unstable operation in complex geological environments; and low sensor integration, making them vulnerable to external interference and leading to poor data accuracy and reliability.

[0006] The landslide multi-layer sliding monitoring mechanism includes a hydraulic cylinder, which is installed at the top center of the inner end of a support frame. An external protective shell is installed at the top center of the inner end of the support frame. A hydraulic telescopic column is installed at the bottom of the hydraulic cylinder, and a connecting plate is fixedly connected to the telescopic end of the hydraulic telescopic column.

A multi-layer landslide monitoring system is installed at the top of the base. The mechanism features an external protective net. A drill bit rod is installed at the center of the base's top to protect the outer cylinder. A hydraulic cylinder drives a hydraulic telescopic column to drill the drill bit rod into the soil. Fiber optic displacement sensors, acceleration sensors, and soil moisture sensors provide real-time, multi-dimensional monitoring of landslide displacement changes, acceleration, and soil moisture content, enabling real-time perception of the multi-layered sliding surface and providing comprehensive data support for landslide early warning. The honeycomb-shaped permeable protective cover prevents direct impact from soil particles, gravel, and other debris on the sensors while ensuring normal water penetration, preventing sensor damage due to water accumulation. The external protective net and drill bit rod protect the outer cylinder, effectively resisting external mechanical collisions and ensuring stable operation of the monitoring mechanism in complex geological environments. Multiple sensors integrated on the surface of the fixed mounting base accurately capture subtle changes within the landslide body, reducing external interference and improving the accuracy and reliability of monitoring data.

A solar panel is installed on the top of the solar panel bracket. A top plate is installed on the top of the solar panel bracket, and a photosensitive sensor is installed on the surface of the top plate.

The device is powered by an automatic light-tracking power supply mechanism. During the power supply process, the photosensitive sensor detects the direction of the light in real time. When the light weakens, it controls the servo motor to work. The servo motor drives the first shaft to rotate, which in turn drives the second drive gear, the second shaft, and the turntable to rotate, changing the orientation of the solar panel. This ensures that the solar panel support is always perpendicular to the sunlight, maximizing solar energy absorption efficiency and improving charging efficiency. This mechanism can convert light energy into electrical energy and store it, providing continuous power to the entire monitoring and early warning device. It is especially suitable for landslide monitoring scenarios in the field without an external power source, ensuring long-term stable operation of the equipment.
