Description

Technical Field

[0001] This utility model relates to the field of engineering survey technology, specifically to a water extraction device for drilling boreholes in engineering surveys. Background Technology

[0002] Engineering survey refers to the investigation and research work that provides geological, topographical, hydrological and other natural conditions and environmental conditions for engineering construction. Engineering survey usually includes engineering geological survey, environmental geological survey, hydrogeological survey, etc. Among them, hydrogeological survey is a more important part of engineering survey projects. It can provide hydrogeological data for engineering design and construction. Geologists will first obtain survey holes by drilling, and then use water sampling equipment to extend from the survey holes to the ground to carry out groundwater sampling operations.

[0003] When using existing engineering exploration borehole water sampling devices, geologists typically use ropes to lower bucket samplers deep into the borehole to perform water sampling. During this process, since most bucket samplers are open or semi-open structures, they are often filled with water at other depths before reaching the intended water sampling location. This limits their ability to sample water at different depths as needed, which is detrimental to hydrogeological exploration work. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-7As shown, a water sampling device for engineering exploration boreholes includes a base 1, with side plates 3 vertically mounted on the top of both sides of the base 1. A winding drum 4 is provided between the side plates 3. A sampling port 6 is provided at the end of the base 1 away from the side plates 3. A support column 9 is provided on one side of the sampling port 6, with its bottom end connected to the base 1 and a first controller 10 installed at its top. A winding rope 5 is provided on the outside of the winding drum 4. A pulley assembly 7 is provided on one side of the winding drum 4 to guide the winding rope 5 smoothly in and out of the sampling port 6. By providing the pulley assembly 7, the water sampling component can be easily fed into the exploration borehole vertically from the sampling port 6. A drive assembly 8 is provided on the outside of one of the side plates 3 to provide rotational force to the winding drum 4. By providing the drive assembly 8, the winding drum 4 can be driven to rotate in both directions to perform the winding and unwinding of the winding rope 5. The sampling tube 12 is located below the sampling port 6. A first fixed tube 13 is fixedly connected to the outer side of the top of the sampling tube 12. A mounting shell 14 is fixedly connected to the top of the first fixed tube 13. A second controller 15 is installed inside the mounting shell 14. It should be noted that the first controller 10 can be a control panel with an LCD touch screen or a PLC controller, while the second controller 15 can be an integrated motherboard or a microcontroller. The first fixed tube 13 is provided with an opening and closing component 16 that keeps the sampling tube 12 closed before it reaches the designated depth. By setting the opening and closing component 16, the sampling tube 12 can be kept closed as it goes deeper into the exploration hole. This avoids the situation where the sampling tube 12 is filled with water at other depths before it reaches the predetermined water sampling position, which makes it convenient for geologists to sample water at different depths as needed.

[0029] The pulley assembly 7 includes a guide wheel 71 disposed on one side of the winding drum 4. Support plates 72 are provided on both sides of the guide wheel 71. One end of each support plate 72 is connected to a side plate 3. The guide wheel 71 is rotatably connected to both support plates 72. The bottom of the winding rope 5 contacts the guide wheel 71. Figure 1 , Figure 2 As shown, the guide wheel 71 allows the entire sampling tube 12 to pass smoothly through the center of the sampling port 6 and enter the exploration hole, thus ensuring the accuracy of the depth reached by the sampling tube 12 and facilitating the water sampling operation.

[0030] The drive assembly 8 includes a support base 81 fixed to one side of the side plate 3, and a winding drum 4 rotatably connected to both ends of the side plates 3. A first motor 82 is fixedly mounted on the top of the support base 81. One end of the winding drum 4 passes through the side plate 3 and is connected to the output end of the first motor 82. The first motor 82 is connected to the terminal of the first controller 10 via a data cable. Figure 1 , Figure 2 and Figure 6 As shown, the first motor 82 can drive the winding drum 4 to rotate in both directions to perform the winding and unwinding of the winding rope 5, thereby allowing the sampling cylinder 12 to enter the exploration hole to perform water sampling.

[0031] The opening and closing assembly 16 includes a first water collection chamber 168 located at the top of the inner cavity of the sampling cylinder 12. A motor compartment 161 is located at the top of the first water collection chamber 168. A second motor 162 is fixedly installed inside the motor compartment 161. The output end of the second motor 162 extends through the inside of the first fixed cylinder 13 and is fixedly connected to a disc seat 163. A second fixed cylinder 164 is fixedly connected to the bottom of the disc seat 163. At least three second water inlets 166 are opened on the outer side of the second fixed cylinder 164. First water inlets 165, corresponding to the second water inlets 166, are opened on the inner wall of the first water collection chamber 168. Filter grooves 167 are intermittently and equally spaced on the outer side of the first fixed cylinder 13. The second motor 162 is connected to the wiring terminal of the second controller 15 via a data cable. Figure 3 , Figure 4 and Figure 5 As shown, when the sampling tube 12 is driven into the exploration hole to a predetermined depth by the drive assembly 8, the second motor 162 drives the disc seat 163 to rotate. The disc seat 163 then drives the second fixed tube 164 located between the first fixed tube 13 and the sampling tube 12 to rotate until the second water inlet 166 on the outside of the second fixed tube 164 coincides with the first water inlet 165 on the inner wall of the first water collection chamber 168. At this time, the first water collection chamber 168 and the exploration hole are kept unobstructed, and groundwater can enter the first water collection chamber 168, which makes it convenient for geologists to sample water at different depths as needed.

[0032] A second water collection chamber 18 is located at the bottom of the inner cavity of the sampling cylinder 12. A leakage channel 17 is located at the top of the second water collection chamber 18. The second water collection chamber 18 is connected to the interior of the first water collection chamber 168 through the leakage channel 17. A liquid outlet 20 is located at the bottom of one side of the second water collection chamber 18. A solenoid valve is installed inside the liquid outlet 20. A liquid level sensor 19 is fixedly installed on the inner wall of the second water collection chamber 18. The liquid level sensor 19 and the solenoid valve are both connected to the terminals of the second controller 15 via data cables. Figure 3 , Figure 4 As shown, the water entering the first water collection chamber 168 through the first inlet 165 will flow into the second water collection chamber 18 through the leakage channel 17. The liquid level sensor 19 can be used to help the geologists on the ground understand the groundwater sampling situation. After the sampling work is completed and the sampling tube 12 reaches the ground, the geologists can take out the water by opening the solenoid valve inside the outlet 20, thus realizing the groundwater sampling work.

[0033] The end of the winding rope 5 furthest from the winding drum 4 is connected to the mounting housing 14. A first conductor 28 is located inside the winding rope 5. A conductive slip ring 24 is coaxially located on the outer side of one end of the winding drum 4. The stator of the conductive slip ring 24 is connected to the side plate 3, and the rotor of the conductive slip ring 24 is connected to the winding drum 4. One end of the first conductor 28 is connected to a second conductor 29. One end of the second conductor 29 passes through the winding rope 5 and connects to the rotor terminal of the conductive slip ring 24. The other end of the first conductor 28 is connected to the terminal of the second controller 15. A battery 26 is located below the winding drum 4 and is fixedly mounted on the top of the base 1. A third conductor 30 is connected to the stator terminal of the conductive slip ring 24. One end of the third conductor 30 is connected to the output terminal of the battery 26. The battery 26 is connected to the terminal of the first controller 10 via a data cable. Figure 1 , Figure 6 and Figure 7 As shown, the first wire 28, located inside the winding rope 5, can enter the exploration hole along with the sampling cylinder 12. Then, through the first wire 28, the second wire 29, and the third wire 30, the power of the battery 26 can be supplied to the second controller 15, thus providing power to the opening and closing assembly 16 and the liquid level sensor 19. At the same time, the first wire 28 and the second wire 29 can be rotated together with the winding rope 5 through the conductive slip ring 24, thus preventing the second wire 29 from being damaged due to excessive twisting and preventing the power supply of the battery 26 from being interrupted.

[0034] The top and bottom of the coiled rope 5 are marked with graduations 25, and a waterproof layer 27 is provided on the outside of the graduations 25. The waterproof layer 27 is made of polyvinylidene fluoride or perfluoroethylene propylene material, such as... Figure 1 , Figure 6 and Figure 7 As shown, in actual use, geologists can determine the depth of the sampling cylinder 12 in the exploration hole by checking the scale value 25 on the outside of the winding rope 5. In order to improve the overall service life of the winding rope 5, a waterproof layer 27 made of polyvinylidene fluoride or perfluoroethylene propylene is also provided on the outside of the winding rope 5. Polyvinylidene fluoride and perfluoroethylene propylene are soft plastics with excellent weather resistance, wear resistance and insulation. Moreover, these two materials are usually translucent or transparent and will not affect the display of the scale value 25.

[0035] A second wireless transceiver 23 is fixedly connected to one side of the mounting housing 14. The second wireless transceiver 23 is connected to the terminal of the second controller 15 via a data cable. A strip base 21 is vertically mounted on one side of the support column 9. A first wireless transceiver 22 is fixedly connected to the bottom of one end of the strip base 21. The first wireless transceiver 22 is connected to the terminal of the first controller 10 via a data cable. Figure 2 , Figure 4As shown, the first wireless transceiver 22 can transmit the command issued by the first controller 10 to the second wireless transceiver 23 located deep in the exploration hole in the form of a wireless signal. The second wireless transceiver 23 then transmits the wireless signal to the second controller 15. After receiving the command, the second controller 15 will start the opening and closing component 16 to perform the water intake operation.

[0036] A grip handle 11 is fixedly connected to the top of the support column 9, and multiple omnidirectional brake wheels 2 are symmetrically installed at the bottom edge of the base 1. Figure 1 , Figure 2 As shown, by setting the grip handle 11 and the universal brake wheel 2, this utility model can be easily moved to different water collection sites, which improves portability. After arriving at the water collection site, the sampling port 6 at one end of the base 1 can be aligned with the exploration hole to facilitate the subsequent insertion of the sampling tube 12.

[0037] Working principle: First, geologists use the handle 11 and omnidirectional brake wheel 2 to align the sampling port 6 with the exploration hole to facilitate the insertion of the sampling tube 12. Then, the drive assembly 8 drives the winding drum 4 to unwind the winding rope 5, thereby sending the sampling tube 12 into the exploration hole for water sampling. During the process of the sampling tube 12 entering the exploration hole, the pulley assembly 7 ensures the accuracy of the depth reached by the sampling tube 12. Geologists can read the scale value 25 on the outside of the winding rope 5 to determine the depth position of the sampling tube 12 in the exploration hole. The opening and closing assembly 16 can keep the sampling tube 12 in a closed state, thus avoiding the situation where the sampling tube 12 is filled with water at other depths before reaching the predetermined water sampling position. This allows geologists to sample water at different depths as needed.
