[0034] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0035] like Figures 1-7 As shown, an exploration and sampling device for engineering testing includes: an operation box 1, a door 2 hinged to the operation box 1, a control panel 3 disposed on the operation box 1, a cable winding assembly 4 installed inside the operation box 1, an umbilical cable 5 wound on the cable winding assembly 4, a control panel 6 connected to the umbilical cable 5 via several hooks, a base 7 disposed below the control panel 6, a counterweight ring 8 fixed to the lower surface of the base 7, several sampling canisters 10 arranged in a ring array between the control panel 6 and the base 7, a connecting assembly 9 disposed on the base 7, the control panel 6 and the several sampling canisters 10, an opening and closing assembly 11 mounted on the control panel 6, a spacing assembly 12 mounted on the umbilical cable 5, and scale lines 13 disposed on the umbilical cable 5.

[0036] The take-up and unwind assembly 4 is adapted to take up and unwind the umbilical cable 5, thereby driving the several sampling cans 10 located below the control panel 6 to move vertically in the vertical direction.

[0037] The connecting component 9 is adapted to connect the chassis 7 to the control panel 6, and to assemble a plurality of the sampling tanks 10.

[0038] The opening and closing assembly 11 is adapted to control the sequential opening and closing of the plurality of sampling containers 10;

[0039] The distance setting assembly 12 is suitable for determining the standoff distance of the umbilical cable 5 when the base plate 7 enters the underground water. In use, the operation box 1 is moved to directly above the underground water to be sampled, and then under the control of the winding and unwinding assembly 4, the umbilical cable 5 is controlled to be unwound to control the lowering of the sampling tanks 10 between the control plate 6 and the base plate 7 to approach the underground water. Under the control of the distance setting assembly 12, the distance between the operation box 1 and the underground water surface can be determined by observing the scale line 13, thereby ensuring the accuracy of the depth of the subsequent sampling tanks 10 into the underground water surface, so that the sampling tanks 10 can explore and sample the water at the accurate depth of the underground water, ensuring the accuracy of the sampling. When the sampling tanks 10 reach the required depth of the underground water, the opening and closing assembly 11 is arranged to control the opening of the tank opening of one of the sampling tanks 10, complete the sampling of the underground water at this position, and as the sampling tanks 10 are controlled to reach different depths of the underground water, the opening and closing assembly 11 can control the sampling tanks 10 to collect and sample the underground water at different depths. Therefore, through one device, multi-layer sampling of the underground water can be realized, and the sampling efficiency is high. After sampling is completed, the tank opening of the sampling tank 10 is closed, so that when the subsequent sampling tanks 10 are lowered, the underground water at other water levels will not enter the sampling tank 10 that has been sampled. The underground water samples at different depths are independently stored and will not be disturbed by the underground water at other water levels, ensuring that all the samples taken are in the specified aquifer, making the detection value more accurate and representative. When the sampling is completed, the connecting assembly 9 is controlled to quickly complete the sequential removal of the sampling tanks 10 from the control plate 6 and the base plate 7, thereby facilitating the detection of the water samples in the different sampling tanks 10.

When the umbilical cable 5 is paid out and the control-installed plurality of sampling tanks 10 are lowered to the underground water, the plurality of sampling tanks 10 enter the water, and the ring-shaped float box 16 floats on the water surface, the positioning disc 14 releases the support of the pressure disc 15, so that the pressure disc 15 drives the plurality of pressure rods 18 to move downward, and then the plurality of pressure blocks 19 abut against and trigger the ring-shaped pressure sensor 17. At this time, the pressure sensor transmits a signal to the control panel 3, and the control panel 3 controls the reel assembly 4 to stop working. At this time, the pay-out distance of the umbilical cable 5 is recorded by the scale line 13, and the pay-out distance of the umbilical cable 5 controlled by the reel assembly 4 is the distance of the plurality of sampling tanks 10 entering the water. Thus, the plurality of sampling tanks 10 can accurately collect and sample the water at the corresponding depth of the underground water, thereby ensuring the accuracy of the survey.
