DETAILED DESCRIPTION

[0019] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0020] Reference Figure 1 The present invention discloses a hydrogeological survey and pumping test device, comprising a vehicle body 1, a bracket 2 and a sliding frame 3 slidably connected to the bracket 2. The outer wall of the vehicle body 1 is fixedly connected with a jack 21 on all sides. When the vehicle body 1 stops moving, the output end of the jack 22 can be moved to abut against the ground, thereby improving the stability of the vehicle body 1 after it stops moving. An angle adjustment component 4 for adjusting the pitch angle of the bracket 2 is provided on one side of the upper surface of the rear portion of the vehicle body 1. The angle adjustment assembly 4 includes a support seat 41 fixedly connected to one side of the upper surface of the vehicle body 1 and two angle adjustment hydraulic cylinders 42 rotatably connected to the upper surface of the vehicle body 1 on a side away from the support seat 41. The bracket 2 is rotatably connected to the support seat 41, and the output ends of the two angle adjustment hydraulic cylinders 42 are rotatably connected to the outer side wall of the bracket 2. Through the extension and retraction of the output ends of the angle adjustment hydraulic cylinders 42, the bracket 2 can be driven to rotate along the support seat 41, thereby changing the pitch angle of the bracket 2; A lifting hydraulic cylinder 14 arranged along the length direction of the bracket 2 is fixedly connected to the side of the inner wall of the bracket 2 away from the support seat 41, and the output end of the lifting hydraulic cylinder 14 is fixedly connected to the sliding frame 3. The sliding frame 3 can be driven to slide along the bracket 2 through the extension and retraction of the output end of the lifting hydraulic cylinder 14.

[0021] Reference Figure 1 , Figure 2 and Figure 3 A storage cylinder 5 is fixedly connected to the center of the inner side wall of the sliding frame 3, a winding shaft 6 is rotatably connected to one side of the inner side wall of the sliding frame 3, both ends of the outer side wall of the winding shaft 6 are fixedly connected to a cableway winding roller 7, and a connecting rope 8 is arranged outside the cableway winding roller 7, and a winding motor 9 for driving the winding shaft 6 to rotate is arranged on the outer side wall of the sliding frame 3; Reference Figure 3 and Figure 4 , a setting robot 10 for setting up the connecting cable 8 in the borehole is arranged in the storage cylinder 5, one end of the connecting cable 8 away from the cableway winding roller 7 is fixedly connected to the setting robot 10, a water-stop assembly 11 for sealing with the inner wall of the borehole is slidably connected to the two connecting cables 8, a submersible pump 12 is fixedly connected to the two connecting cables 8 between the water-stop assembly 11 and the setting robot 10, a drainage pipe (not shown in the figure) connected to the submersible pump 12 is arranged at the output end of the submersible pump 12, a pressure sensor 13 is arranged on one side of the outer wall of the submersible pump 12, a display (not shown in the figure) electrically connected to the pressure sensor 13 is arranged in the vehicle body 1, and the display is used to display the pressure change of the pressure sensor 13; A guide pulley block 15 for guiding the connecting rope 8 is arranged on one side of the inner wall of the sliding frame 3 near the winding shaft 6. The erection robot 10 comprises a cylindrical shell 101. Self-driving wheels 102 are arranged around both ends of the outer wall of the cylindrical shell 101. When a water pumping test is required, the angles of the bracket 2, the sliding frame 3 and the storage cylinder 5 are first adjusted to be parallel and aligned with the borehole through the angle adjustment component 4. Then, the lifting hydraulic cylinder 14 drives the sliding frame 3 to move to the side close to the borehole until the storage cylinder 5 is as close to the borehole as possible. Then, the erection robot 10 is placed into the borehole. The self-driving wheel 102 drives the cylindrical shell 101 to move into the borehole. At the same time, the winding motor 9 drives the winding shaft 6 and the cableway winding roller 7 to unwind. The connecting rope 8 follows the cylindrical shell 101 to move into the borehole. The guide pulley block 15 can guide the connecting cable 8 to be parallel to the bracket 2, thereby ensuring that the connecting cable 8 remains parallel to the length direction of the borehole when following the erection robot 10 into the borehole (the unwinding speed of the cableway winding roller 7 should correspond to the moving speed of the erection robot 10 along the borehole, thereby ensuring that the connecting cable 8 is in a straight state as much as possible) and the submersible pump 12 fixedly connected to the connecting cable 8 follows the erection robot 10 to move synchronously into the borehole to the pumping position. When the erection robot 10 moves into the borehole, the submersible pump 12 fixedly connected to the connecting cable 8 follows the erection robot 10 to move synchronously into the borehole to the pumping position. During the movement, when the submersible pump 12 and the pressure sensor 13 are immersed in the water body in the borehole, the pressure sensor 13 is pressurized, resulting in a change in the display reading electrically connected to the pressure sensor 13. At this time, the water surface height in the borehole at this time can be calculated by the unwinding length of the connecting cable 8 and the inclination angle of the borehole; When the submersible pump 12 and the erection robot 10 move to the predetermined position, the self-driving wheel 102 stops rotating, and the supporting cylinder 22 drives the clamping pad 23 to move to the side away from the cylindrical shell 101 to the water filter plate abutting against the inner wall of the borehole, thereby fixing the erection robot 10 and the submersible pump 12, and then starting the submersible pump 12 to wash the inside of the borehole until the water discharged from the drainage pipe of the submersible pump 12 becomes clear; After the well washing is completed, the sliding motor 113 can drive one group of clamping wheels 112 to rotate, thereby driving the water-stop sliding frame 111 to move along the connecting rope 8. When the water-stop assembly 11 moves to the predetermined position (i.e., the water-stop layer), the air pump 117 inflates the airbag 116, thereby expanding the airbag 116, filling the space between the water-stop plate 114 and the borehole pipe wall and the inside of the opening 115, thereby isolating the aquifer where the submersible pump 12 is located and the submersible layer above the water-stop plate 114, and then turning on the submersible pump 12 again for a pumping test. During the well washing process and the pumping test, the positions of the submersible pump 12 and the pressure sensor 13 remain unchanged. At this time, when the liquid level changes, the water pressure on the pressure sensor 13 also changes, and the staff can calculate and record the change in the liquid level in the well at any time by observing the change in the water pressure on the pressure sensor 13. After the pumping test is completed, the air pump 117 first deflates the airbag 116, and then the sliding motor 113 can drive one group of clamping wheels 112 to rotate, thereby driving the water-stop sliding frame 111 to move along the connecting rope 8 to the water-stop assembly 11 to return to the storage tube 5, and then the supporting cylinder 22 drives the clamping pad 23 to move toward the side close to the cylindrical shell 101, and then the self-driving wheel 102 drives the cylindrical shell 101 to move toward the side close to the bracket 2 while the winding motor 9 drives the winding shaft 6 and the cableway winding roller 7 to wind up the connecting rope 8, until the submersible pump 12 and the erection robot 10 are both extracted from the well, and then the submersible pump 12 and the erection robot 10 are manually placed in the storage tube 5; When the water-stop assembly 11, the erection robot 10 and the submersible pump 12 are all reset to the storage tube 5, the lifting hydraulic cylinder 14 drives the sliding frame 3 to move to the side away from the drilling hole until the storage tube 5 is as close to the lifting hydraulic cylinder 14 as possible. During this process, the piston 17 follows the sliding frame 3 to move to the side close to the lifting hydraulic cylinder 14, and squeezes the air between the piston 17 and the air cylinder 16 in the air cylinder 16, so that this part of the gas flows through the air collecting box 18 and the exhaust box 19 and is discharged from the air hole 20. The air flow blows to the water-stop assembly 11, the erection robot 10 and the submersible pump 12 in the storage tube 5, thereby maximizing the drying speed of the water-stop assembly 11, the erection robot 10 and the submersible pump 12, and avoiding the problems of rust on the outer surface of the water-stop assembly 11, the erection robot 10 and the submersible pump 12 and aging of electrical components as much as possible; When the sliding frame 3 moves to the storage tube 5 as close to the lifting hydraulic cylinder 14 as possible, the angle adjustment component 4 readjusts the pitch angle of the bracket 2 to be parallel to the ground, and drives the output end of the jack 21 to move away from the ground to drive the vehicle away.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
