Groundwater monitoring is a fundamental task in the sectors of water conservancy, environment, geology, traffic, agriculture and the like. The reason for the rise and fall of the groundwater level is various, and the groundwater level is mainly influenced by geological factors such as general lithology, aquifer structure, hydrometeorological factors such as rainfall, air temperature and artificial factors, irrigation and the like, and is probably a comprehensive result of several factors at some times. The rising of the diving position can cause unfavorable phenomena of salinization of soil, enhancement of corrosivity of underground water and rock soil to buildings, collapse of rock soil body and the like to the rock-warrior engineering; the excessive decline of underground water often induces geological disasters such as ground collapse, settlement, ground fissure and the like, and environmental problems such as underground water quality deterioration, water source exhaustion and the like, thereby causing great threats to the stability of buildings and rock-soil bodies and the living environment of human beings.
At present, the Chinese patent with publication number CN106382971B and publication date of 2017, 12 and 19 discloses a multifunctional low-light-level underground water level monitoring device and a system thereof, wherein the multifunctional low-light-level underground water level monitoring device comprises a shell, a low-light-level observer, a light source and a spacer; the shell is arranged at the wellhead of the observation well to prevent external light from entering the observation well; the low-light-level viewer is used for receiving light beams emitted by the light source and acquiring video information of the well wall; the isolating piece is fixedly connected with the light source; the barrier floats on the liquid in the observation well and is used for blocking the light beam of the light source from penetrating through the barrier layer.
When the device is used, the light source fixed on the isolating piece is thrown to the bottom of the well, one side of the isolating piece far away from the light source is in contact with the water surface, and the photoelectric data obtained by the low-light-level observer is processed by the processor, and meanwhile, the distance H between the low-light-level lens and the water surface (light source) in the observation well can be obtained. The underground water level calculation method comprises the following steps: h2= H-H1, wherein H1 is the vertical distance from the micro-lens to the base after the device is leveled, and H2 is the height difference between the measured underground water level and the ground surface.
In view of the above related technologies, the inventor believes that the groundwater has fluidity, the spacer floats on the water surface and may float on the water surface under the flow of water, and when the light source and the micro-lens are not in the same horizontal line, the distance from the micro-lens to the light source in the observation well measured at this time will be greater than the vertical distance from the micro-lens to the light source, so that the monitoring data is not accurate enough; and the isolating piece may collide the well wall when swinging on the water surface, so that the isolating piece is suddenly high and suddenly low, and further the monitoring data is not accurate enough.
