Description

Technical Field

[0001] The present invention relates to the field of hydrogeological exploration, and in particular to a device and method for observing groundwater levels in hydrogeological exploration. Background Art

[0002] Hydrogeological exploration is a method of investigation that studies groundwater resources and their distribution, movement, and quality characteristics. It investigates and analyzes the geological background of the study area, including studies of strata, structure, and landforms. This provides basic information for subsequent groundwater exploration. Groundwater refers to water stored in rock pores below the ground. In a narrow sense, it refers to water in saturated aquifers below the groundwater table. Groundwater is an important component of water resources. Due to its stable water volume and good water quality, it is one of the important water sources for agricultural irrigation, industry, mining, and cities. However, under certain conditions, changes in groundwater can also cause adverse natural phenomena such as swamping, salinization, landslides, and ground subsidence.

[0003] Currently, when measuring the water level of a borehole, well, water level pipe, or vertical bank, a detector is inserted into the hole and connected to a water level observation and measuring instrument via a graduated rope to detect the water level. During the dry season, when the groundwater level is too low, the groundwater level will be lower than the measuring borehole. Directly inserting the measuring instrument into the borehole will prevent the measuring instrument from moving and detecting according to the surrounding conditions at the bottom of the borehole, thereby affecting the observation of the groundwater level. Summary of the Invention

[0004] The present invention provides a groundwater level observation device and method for hydrogeological exploration, which solves the problem that when the groundwater level is too low, the groundwater level will be lower than the measuring borehole. When the measuring instrument is directly placed in the measuring borehole, the measuring instrument cannot move and detect according to the surrounding conditions at the bottom of the measuring borehole, thereby affecting the water level observation of the groundwater level.

[0011] Furthermore, a connecting rope is fixed to the top of the measuring cylinder, and a signal line is provided between the measuring cylinder and the control panel.

[0012] Furthermore, one end of the signal line is connected to the first hydraulic rod and the second hydraulic rod respectively.

[0013] Furthermore, a control line is provided on the connection block, and one end of the control line is connected to one end of the signal line.

[0020] Step 3: Using the buttons on the control panel, the first hydraulic rod is activated, so that the blocks on the four shafts are fixed on the inner wall of the measuring borehole, and the second hydraulic rod is activated, so that the output end of the second hydraulic rod is disengaged from the slot of the connecting block, causing the moving cylinder to fall off and fall into the groundwater level;

[0021] Step 4: Use the buttons on the control panel to control the third hydraulic rod and the motor to operate the moving cylinder to move, and display the position of the locator and the water level data detected by the water level sensor in real time on the display screen.

By controlling a third hydraulic rod and a motor, the motor drives the blades to rotate, so that the movable cylinder moves. The shaft block on the third hydraulic rod slides in the slide groove of the fixed block to control the rotation direction of the blade, thereby controlling the movement direction of the movable cylinder.

When the measuring instrument is directly placed in the measuring borehole, the measuring instrument cannot perform mobile detection according to the surrounding conditions at the bottom of the measuring borehole, thereby affecting the water level observation of the groundwater level.
