[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0030] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0031] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0032] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] As mentioned in the background technology, traditional water level monitoring methods have some limitations, such as unstable sensor installation and susceptibility to water level fluctuations. These problems may lead to inaccurate monitoring data, thereby affecting the reliability of the early warning system.

[0034] In order to improve the above problems, the present application proposes a groundwater monitoring and early warning device, which drives the drill bit to rotate by a motor so that the device can be firmly fixed in the soil, avoiding the problem that the traditional water level sensor cannot be stably installed at the bottom of the reservoir. This stable installation method helps to reduce the shaking of the sensor caused by water level fluctuations, thereby improving the accuracy of the monitoring data. The device can adjust its depth in the soil according to actual needs, and adapt to different monitoring requirements through the movement of the telescopic component, so that it can more flexibly respond to different water level changes; the design of the first electric rotating shaft allows the connecting rod to rotate upward and be perpendicular to the ground. Such a structure not only helps to fix the device, but also prevents the device from tilting or shifting due to external forces, ensuring long-term and stable monitoring effects. Since the device can be automatically fixed in a suitable position, the need for manual intervention is reduced, and the monitoring efficiency and automation level are improved. Since the device can adapt to different soil conditions and water level changes, it has strong environmental adaptability and can be used under a variety of geological conditions.
