The seat body 1 is connected to a frame body 6 through a column 4, and a driving member 8 is arranged on the outer wall of one side of the frame body 6. The specific structure of the driving member 8 is not limited. In this embodiment, preferably, the driving member 8 adopts a stepping motor, and a roller 7 is arranged at the driving end of the driving member 8, and a traction rope 9 is wound around the roller 7, and also includes:

[0026] An exploration mechanism, which is arranged at the end of the traction rope 9 and is used to float on the surface of the groundwater level;

[0027] A tensioning mechanism, which is arranged on the base body 1 and is used to tighten the traction rope 9 when the exploration mechanism floats on the surface of the groundwater level;

[0028] The limiting mechanism is arranged on the seat body 1 and is used to limit the position of the seat body 1 .

[0029] The device can be moved to the vicinity of the groundwater level exploration port by the moving wheel 2, and then the position of the seat body 1 can be fixed by the limiting mechanism to ensure the stability of the device during exploration, and then the roller 7 is driven to rotate by the driving member 8, and the exploration mechanism is lowered into the exploration port by the traction rope 9 until the exploration mechanism floats on the groundwater surface. At this time, the traction rope 9 will be in a loose state, and the traction rope 9 can be tightened by the tightening mechanism to facilitate reading the scale on the traction rope 9. At the same time, the accuracy of depth measurement is also improved, and the use effect is better.

[0030] As an embodiment of the present invention, please refer to Figure 2 and Figure 3 The exploration mechanism includes a counterweight 11, a lifting ring 25 is connected to the counterweight 11 through a connecting rope, and one end of the traction rope 9 is connected to the lifting ring 25, a floating component is arranged on the outside of the counterweight 11, and a sampling component is also arranged in the counterweight 11.

[0031] As an embodiment of the present invention, please refer to Figure 2 and Figure 3 The floating assembly includes a floating block 20 sleeved on the outside of the counterweight 11, and side panels 22 are also provided on the outer walls of both sides of the counterweight 11. A movable rod 21 penetrating the side panels 22 is provided on the floating block 20, and a stopper 23 is provided at the end of the movable rod 21. When the counterweight 11 falls into the groundwater, due to the action of the floating block 20, the floating block 20 and the counterweight 11 can be suspended on the water surface together, which is convenient for measuring the depth of the groundwater.

[0032] As an embodiment of the present invention, please refer to Figure 2 and Figure 3The sampling assembly includes a cavity 12 opened in the counterweight 11, and a telescopic member 13 is fixedly provided on the counterweight 11, and the specific structure of the telescopic member 13 is not limited. In this embodiment, preferably, the telescopic member 13 adopts an electric telescopic rod, and a piston plate 14 is provided at the telescopic end of the telescopic member 13, and the piston plate 14 is located in the cavity 12. The outer wall of the counterweight 11 is also provided with a water pump 18 connected to the cavity 12, and the outer wall of the piston plate 14 is provided with a fixed rod 15 that penetrates the water pump 18, and the end of the fixed rod 15 is provided with a closing plate 16, and a sealing member is provided on the closing plate 16 17.

When the counterweight 11 is suspended in the groundwater, the piston plate 14 can be driven to move in the cavity 12 through the telescopic member 13, and the groundwater can be pumped into the cavity 12 through the pumping cylinder 18. With the continuous movement of the piston plate 14, the closing plate 16 can be driven to move synchronously until the sealing member 17 on the closing plate 16 contacts the pumping cylinder 18, which can block the pumping cylinder 18, so that the groundwater can be stored in the cavity 12, thereby realizing the groundwater sampling operation.

[0033] As an embodiment of the present invention, please refer to Figure 2 The exploration mechanism also includes a trigger component, which includes a touch switch 19 arranged on the inner wall of the cavity 12, and a touch switch 24 arranged on the side plate 22.

When the counterweight 11 sinks into the groundwater, the movable rod 21 on the floating block 20 will move on the side plate 22 until the floating block 20 contacts the touch switch 24, which can trigger the telescopic member 13 to work and perform water pumping operation until the closing plate 16 contacts the pumping cylinder 18. At this time, the piston plate 14 just contacts the touch switch 19, triggering the telescopic member 13 to stop working, which can effectively realize the automatic extraction and sealing of groundwater when the exploration mechanism contacts the groundwater, and the use effect is better.

[0034] As an embodiment of the present invention, please refer to Figure 4The tensioning mechanism includes a square tube 26 and a support rod 5.

In this embodiment, preferably, the driving member 28 adopts a servo motor, and a rotating wheel 29 is arranged at the driving end of the driving member 28, and a rubber sleeve 30 is arranged on the outer wall of the rotating wheel 29. When the traction rope 9 is in a loose state, the rotating wheel 29 can be driven to rotate by the driving member 28. Since there is a certain friction between the rubber sleeve 30 on the rotating wheel 29 and the traction rope 9, the traction rope 9 can be straightened by the rotating rubber sleeve 30, which is convenient for reading data and has a better use effect.

[0035] As an embodiment of the present invention, please refer to Figure 1 and Figure 5 The limiting mechanism includes a ground pile 3, a through hole distributed in an annular shape with equal distances is opened on the base body 1, and the ground pile 3 is arranged in the through hole, and grooves 31 are opened on the inner walls on both sides of the through hole, and the inner wall of the groove 31 is connected with a block 33 through an elastic member 32, and the specific structure of the elastic member 32 is not limited. In this embodiment, preferably, the elastic member 32 adopts a spring, and a chamfer is opened on one side of the block 33, and a groove that matches the block 33 is opened on the outer wall of the ground pile 3. When the device moves to a suitable position, the ground pile 3 can be pressed, so that the ground pile 3 pushes the block 33 to both sides and compresses the elastic member 32 until the ground pile 3 is inserted into the soil, which can effectively ensure the stability of the base body 1, and after the survey, the ground pile 3 can be pulled out, and under the resetting action of the elastic member 32, the block 33 can be re-stuck in the groove on the ground pile 3, so that the ground pile 3 can be reused, and the use effect is better.

[0036] When in use, the device can be moved to the vicinity of the groundwater level exploration port by the moving wheel 2, and then the position of the seat body 1 can be fixed by the limiting mechanism first, so as to ensure the stability of the device during exploration, and then the roller 7 is driven to rotate by the driving member 8, and the exploration mechanism is lowered into the exploration port by the traction rope 9 until the exploration mechanism floats on the groundwater surface. At this time, the traction rope 9 will be in a loose state, and the traction rope 9 can be tightened by the tightening mechanism, so as to facilitate the reading of the scale on the traction rope 9. At the same time, the accuracy of depth measurement is also improved, and the use effect is better.

[0037] It should be particularly noted that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
