[0002] Hydrogeological survey, also known as hydrogeological survey, refers to the hydrogeological investigation and research work carried out to find out the hydrogeological conditions of a region. It aims to understand the causes, distribution and movement laws of groundwater and surface water. It provides a basis for the rational exploitation and utilization of water resources and the correct design and construction of foundation and piling projects. It includes two aspects: underground and above-ground hydrological survey. Underground hydrological survey mainly investigates and studies the changes in groundwater levels, flow directions, chemical composition, etc. at different times of the year, finds out the burial conditions and corrosiveness of groundwater, determines the changes and impacts that groundwater may have during the construction and use of buildings, and puts forward prevention and control suggestions.

[0020] Working principle: Before using the present invention, the base 1 is placed at the drilling sampling location, and then the device is assembled. After the assembly is completed, the moving platform 7 is located at the upper half of the threaded shaft 6; When the present invention is used, the driver 8 works to drive the connecting rod 9 to rotate, and then the driving motor 5 works to drive the threaded shaft 6 to rotate, so that the moving platform 7 moves downward, thereby driving the rotating drilling tool 13 to drill the soil. When the top of the connecting rod 9 is about to be touched by the ground, the connecting rod 9 is disconnected from the output end of the driver 8, and then the driving motor 5 drives the threaded shaft 6 to rotate in the opposite direction, thereby driving the moving platform 7 to move upward to a suitable position, and a new connecting rod 9 is taken, and the bottom end of this connecting rod 9 is connected to the top of the lower connecting rod 9, and the top of this connecting rod 9 is connected to the output end of the driver 8, in this way, until the cylinder 12 is located at the target depth of drilling; When the cylinder 12 reaches the target depth for soil sampling, the driving motor 5 will stop working and the driver 8 will work slowly. At the same time, the control motor 191 drives the driving gear 192 to rotate forward, and the driving gear 192 will rotate the gear ring 193. During the rotation of the gear ring 193, the upper rotating head 195 will contact the rotating head 184, and the gear ring 193 will continue to rotate. Under the action of the limiting plate 197, the upper rotating head 195 will drive the rotating head 184 to rotate, and the rotation of the rotating head 184 will drive the rotating rod 183 and the arc tooth 2 182 to rotate. The rotation of the arc tooth 2 182 will drive the meshing arc tooth 1 181 to rotate and squeeze the curved spring 186. The arc tooth 1 181 will drive the fixed rod 17 to rotate, so that the end of the arc plate 15 away from the fixed rod 17 protrudes from the curved surface of the cylinder 12 When the driver 8 drives the cylinder 12 to rotate, the protruding arc plate 15 will scrape the soil into the space formed by the isolation plate 14 and the arc plate 15. When the gear ring 193 continues to rotate, the rotating head 195 will not contact the rotating head 184, and the curved spring 186 will push the arc tooth 182 to reverse and reset, thereby closing the arc plate 15. At this time, the space formed by the isolation plate 14 and the arc plate 15 will be filled with a proper amount of soil. During the process, when the positively rotating lower rotating head 195 contacts the sealing head 202, the sealing head 202 is limited, so that the lower rotating head 195 will be driven and bent by the sealing head 202. After passing through the sealing head 202, the lower rotating head 195 is reset by the lower elastic sheet 196, and the gear ring 193 continues to rotate to drive the next arc plate 15 to open; When sampling groundwater, the drive motor 5 and the drive 8 will stop working. At the same time, the control motor 191 drives the drive gear 192 to reverse, and the drive gear 192 reverses the toothed ring 193. During the rotation of the toothed ring 193, the rotating head 195 below will contact the elastic rod 203. The rotating head 195 will drive the sealing head 202 to deflect and squeeze the elastic rod 203, so that the waterway 201 and the space formed by the isolation plate 14 and the arc plate 15 are opened, and the groundwater will enter the interior of the space. After taking an appropriate amount of water sample , the lower rotating head 195 continues to rotate over the sealing head 202, and the elastic rod 203 will push the sealing head 202 to reset, so that the waterway 201 is in a closed state; during the process, when the reversed upper rotating head 195 contacts the rotating head 184, the arc-shaped tooth 2 182 is limited, so that the upper rotating head 195 will be driven and bent by the rotating head 184, and after passing the rotating head 184, the upper rotating head 195 is driven to reset by the upper elastic sheet 196, and the gear ring 193 continues to rotate to drive the next waterway 201 to open; When soil and groundwater sampling are performed at the same depth, the control motor 191 drives the driving gear 192 to rotate forward, and the driving gear 192 rotates the toothed ring 193. During the rotation of the toothed ring 193, the upper rotating head 195 will contact the rotating head 184, and the toothed ring 193 continues to rotate. The upper rotating head 195 will drive the rotating head 184 to rotate. The rotation of the rotating head 184 will drive the rotating rod 183 and the arc-shaped tooth 2 182 to rotate. The rotation of the arc-shaped tooth 2 182 will drive the meshing arc-shaped tooth 1 181 to rotate and the extrusion spring 186. The arc-shaped tooth 1 181 will drive the fixed rod 17 to rotate, so that the arc plate 15 is away from the fixed rod. One end of 17 protrudes from the curved surface of the cylinder 12, maintaining the opening size until the interior of the space formed by the isolation plate 14 and the arc plate 15 is filled with an appropriate amount of soil. Subsequently, the control motor 191 drives the driving gear 192 to reverse, and the driving gear 192 reverses the toothed ring 193. During the rotation of the toothed ring 193, the rotating head 195 at the lower opposite side will contact the elastic rod 203. The rotating head 195 will drive the sealing head 202 to deflect and squeeze the elastic rod 203, so that the waterway 201 and the space formed by the isolation plate 14 and the arc plate 15 are opened, and the groundwater will enter the interior of the space, thereby quickly completing the soil and groundwater sampling.
