Description

Technical Field

[0001] The invention relates to the technical field of coalfield hydrogeological exploration, and more particularly to a coalfield hydrogeological exploration water sample detection device. Background Art

[0002] During coalfield geological surveys, it is also necessary to investigate the distribution, movement, and change patterns of groundwater in the coalfield area. By understanding the distribution and movement patterns of groundwater, it is possible to effectively predict the risk of water disasters, so that relevant response measures can be taken during coalfield mining. Then, a special water sampling device can be used for water pumping tests to quantitatively extract groundwater. Then, the built-in water quality detection structure can be used to test parameters such as groundwater permeability. Therefore, it is possible to reasonably use groundwater resources based on relevant data, reduce dependence on external water sources, improve the utilization rate of coal resources, and promote the sustainable development of the coal industry. In summary, the inventors have found that the existing water sample detection device has the following main defects: since the current water sample detection device extracts and detects groundwater quantitatively, it is unable to implement real-time monitoring of the changes in the groundwater level during the extraction process, so that when the extraction exceeds the amount, the groundwater level drops significantly and it is very easy to cause changes in internal pressure, thereby leading to subsidence of the coalfield surface, making it easy for the coalfield surface to become unstable and reducing the safety factor of coalfield exploration. Therefore, the sampling and detection intensity of the detection device for groundwater will be reduced. Summary of the Invention

[0036] Among them, the detection structure 375 is also provided with an assembly block 3751, and the assembly block 3751 passes through the edge position of the frame 3752 and the center of the frame 3752 is connected to a center plate 3753 to position the camera 3755, and a fill light 3754 is also connected to the edge position of the center plate 3753.

During the process, the connecting plates 5 on the left and right sides can ensure the verticality of the new detection structure 3, and prevent the detection from being unstable due to the influence of shaking during operation. Subsequently, the detection body 32 of the new detection structure 3 can be spliced ​​with the connecting plates 5 through the support rods 31 on the left and right sides to improve the verticality of the detection body 32 during operation. Then, the sealing cover 34 at the upper end of the detection body 32 can make the top easy to disassemble and assemble, and at the same time, the control panel 33 can be used to control the water pump 36 and the pressure of the parallel plate 35 at the lower end.

At the same time, the water pump 36 can sample the groundwater through the vertical pipe 37 and guide it upward to the detection body 32 for groundwater detection, and detect its permeability and hydrogeological parameters, so as to ensure the safety factor during subsequent coal mining. At the same time, with the cooperation of the pressure detector 38, the operation can be stopped immediately when an abnormality occurs to prevent the occurrence of coalfield subsidence. On the contrary, after the groundwater detection is completed, the water pump 36 is reversed to pump the groundwater inside the detection body 32 into the detection body 32. The water is led out and discharged to the underground area of ​​the coalfield again, so that the position of the underground water area of ​​the coalfield can be restored to its original state after the detection is completed, and then the pipe body 373 of the vertical pipe 37 can be connected to the water pump 36 through the top connecting end 372. Then the through groove 371 is used to allow the groundwater to circulate, and the bottom penetration layer 374 is used to allow the groundwater to circulate. Finally, the edge detection structure 375 can be used in combination with the pressure detector 38, so that the detection structure 375 can position the frame 3752 through the assembly block 3751, and then the center plate 3753 of the frame 3752 fixes the camera 3755, so that after the camera 3755 enters the underground water environment, it can be combined with the edge fill light 3754 to detect the changes in the internal soil layer.

[0041] Example 2: Figures 6 and 7 As shown: The present invention provides a water sample detection device for coalfield hydrogeological exploration. Its structure includes: the pressure detector 38 is provided with a conductive block 381, the lower end of the conductive block 381 is connected to the ultrasonic rod body 382, ​​and the surface of the ultrasonic rod body 382 is opened with an echo groove 383, and the middle and lower part is also opened with a vertical rail 384 for the sliding rod 385 to be embedded, and the lower end of the sliding rod 385 is also connected to a reinforcement block 386.

[0042] Among them, an electrical connection groove is opened in the conductive block 381 for electrical connection with the circuit of the control panel 33. The ultrasonic rod body 382 is vertical and the vertical rail 384 in the middle and lower position allows the slide rod 385 to be installed and its edge is limited. The bottom of the slide rod 385 is also connected to a triangular solid anti-rust reinforcement block 386.

[0043] The upper end of the slide rod 385 is also connected to a slot 3851 , and the slot 3851 is opened at the lower end center of the slider 3852 , and positioning plates 3853 are connected to the left and right sides of the surface of the slider 3852 to position the electric wheel 3854 .

[0044] Among them, the slider 3852 is engaged with the top of the slide rod 385 through the slot 3851, and the positioning plate 3853 on the surface has a circular groove to allow the electric wheel 3854 to be positioned, and a built-in small drive motor is electrically connected to the control panel 33 through a line.

[0045] Specific functions and operation procedures of this embodiment: In the present invention, the conductive block 381 of the pressure detector 38 will be positioned and connected to the parallel plate 35 by embedding. At the same time, the ultrasonic rod 382 can use the propagation and reflection principle of ultrasonic waves in combination with the echo groove 383 opened on the surface to measure the liquid level. When the ultrasonic pulse encounters the liquid surface, part of the sound energy is reflected back. By measuring the round-trip time of the ultrasonic wave, the height of the liquid surface can be calculated. For this reason, the liquid level after the groundwater is sampled can be accurately determined. Then, when slowly sampling, the limit of the pressure change in the groundwater area can be judged according to the gradual decrease in the liquid level, so that the subsequent prevention plan can be accurately arranged. Then, the vertical opening in the middle and lower parts can be used to measure the liquid level. The rail 384 can make the slide bar 385 slide vertically, so that the bottom of the slide bar 385 can be embedded in the soil layer through the triangular reinforcement block 386 to complete support and fixation, ensuring the vertical fixation of the ultrasonic rod body 382 to prevent tilting, and then the slider 3852 at the upper end of the slide bar 385 can complete the stable engagement with itself through the slot 3851, and then use the positioning plate 3853 set on the surface to determine the position of the electric wheel 3854, and then drive the electric wheel 3854 to rotate according to the small driving motor carried. Therefore, when the electric wheel 3854 rotates on the edge of the vertical rail 384, it can improve the smoothness of the up and down sliding of the slide bar 385 and the convenience of resetting.
