Description

Technical Field

[0001] The present invention relates to the technical field of groundwater sampling and monitoring, and in particular to a groundwater monitoring and sampling integrated device for hydrogeological survey. Background Art

[0002] In hydrogeological surveys, groundwater sampling and monitoring play a vital role. Groundwater sampling and monitoring can directly obtain information on the physical and chemical properties of groundwater, such as water temperature, pH value, dissolved oxygen, mineral content, etc., so as to comprehensively evaluate the quality of groundwater. These data are crucial for determining whether groundwater is suitable for drinking, agricultural irrigation or industrial use.

[0003] And through regular sampling, the water quality and water level changes of groundwater can be monitored. This long-term monitoring helps to discover potential environmental problems, such as groundwater pollution, abnormal rise and fall of water levels, etc. For areas prone to geological disasters, this monitoring is particularly important because it can detect groundwater anomalies in time, providing valuable time for disaster warning and emergency response.

[0004] At present, operators often use simple sampling equipment such as buckets to conduct sampling and monitoring when monitoring groundwater. However, these devices can only obtain samples of a certain depth at a time, and will more easily affect the water layer distribution of groundwater when repeatedly probing. This not only increases the labor intensity of operators, but also easily affects the collection accuracy and monitoring effect of water samples at different depths. In this regard, an integrated device that can perform multi-depth point sampling and monitoring of groundwater is proposed to solve the above problems. Summary of the invention

[0013] Description: The clamping transmission mode of the straight-line protrusion and the straight-line concave block is adopted, which facilitates the liquid collecting box to slide up and down from the connecting part of the control rod to quickly adjust the vertical height position of the liquid collecting box. The transmission mode is reliable and can effectively realize the synchronous rotation of the first rotating block and the second rotating block.

[0023] Note: The threaded carrier plate can be quickly assembled by using a detachable snap-on method, thereby facilitating the removal of the control lever and the liquid collecting box as a whole, and adjusting the position of the liquid collecting box.

DETAILED DESCRIPTION

[0043] The present invention is further described in detail below in conjunction with specific implementation methods to better reflect the advantages of the present invention.

[0044] Embodiment 1: An integrated groundwater monitoring and sampling device for hydrogeological survey, such as Figure 1 As shown, it comprises a cylinder 1, a plurality of liquid collecting boxes 2 slidably disposed in the cylinder 1, and a control rod 3 for connecting each of the liquid collecting boxes 2, and the cross section of the cylinder 1 is a regular hexagon;

[0045] like Figure 2 , Figure 3 As shown, the six inner walls of the cylinder 1 are provided with guide rails 11 for the liquid collecting box 2 to move up and down, and the six side walls of the liquid collecting box 2 are provided with sliders 21 slidably connected with the guide rails 11.

[0046] like Figure 1 As shown, the top surface of the cylinder 1 is provided with a threaded carrier 4. Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the control rod 3 is composed of a threaded portion 31 for connecting to the threaded carrier 4 and a connecting portion 32 for fixing the liquid collecting box 2, the threaded portion 31 and the connecting portion 32 are connected to the upper and lower limits by rotating with the snap ring through an annular groove, the threaded portion 31 and the connecting portion 32 are both hollow rod bodies, and a center rod 33 is rotatably arranged inside the control rod 3, the connecting portion 32 is provided with six first rotating blocks 34 connected to the liquid collecting box 2 in a group, and the first rotating blocks 34 are arranged at an equal interval angle of 60°, and the center rod 33 is provided with a gear ring 36 meshing with a gear 35 provided at the inner end of the first rotating block 34. Figure 5 As shown, the inner wall of the connecting portion 32 corresponding to the position of the gear ring 36 has an annular groove to meet the meshing transmission of the gear ring 36 and the gear 35, and the side wall of the through hole of the liquid collecting box 2 is provided with a second rotating block 22, and the inner end of the second rotating block 22 is provided with a transmission screw 23, and the first rotating block 34 is slidably engaged with the second rotating block 22. Specifically, the outer end of the first rotating block 34 is provided with a straight-line protrusion, and the outer end of the second rotating block 22 is provided with a straight-line concave block for matching with the straight-line protrusion, and the straight-line protrusion and the straight-line concave block are coated with a magnetic coating, and the magnetic coating is selected from commercially available magnetic coatings.

[0047] like Figure 7 , Figure 8 As shown, the liquid collecting box 2 is provided with liquid bins 24 corresponding to the second rotating blocks 22 one by one, and the side walls of the liquid collecting box 2 corresponding to each of the liquid bins 24 are provided with liquid guide tubes 25 connected to the liquid guide tubes 25 with limited sliding seals, and the transmission screw 23 is threadedly connected with the screw disc 26 provided at the inner end of the liquid guide tube 25, so as to push the liquid guide tube 25 to move outward.

[0048] like Figure 5 As shown, a plurality of latch holes 321 are sequentially arranged on the side of the connecting portion 32 from top to bottom, and latches 5 for being plugged and fixed with the latch holes 321 of the connecting portion 32 are arranged on the upper and lower end surfaces of the liquid collecting box 2. The latch holes 321 are arranged according to the positions of the scale scales, for example, a group of latch holes is arranged at every 30 cm vertical height.

[0049] like Figure 2 As shown, thirteen liquid inlets 12 are arranged on the inner walls of the six sides of the cylinder 1 located in the guide rail 11 from top to bottom. For example, the distance between two adjacent liquid inlets 12 is 30 cm. The liquid inlet 12 is provided with a rotating tube 13 which is rotatably sealed and connected thereto. Fig. 9 , Fig.10 As shown, one end of the liquid guide tube 25 is threadedly connected to the tube hole of the rotating tube 13. Specifically, as shown in Fig.10 , Fig.11As shown, the liquid guide tube 25 has a thread, and the thread has an arc angle of 30° from the starting end to the terminal end, so that the protrusion on the inner wall of the rotating tube 13 rotates exactly 30° under the cooperation transmission, and a plurality of liquid inlet channels 121 are provided on the liquid inlet 12, and a plurality of docking ports 131 staggered with the liquid inlet channels 121 are provided on the side wall of the rotating tube 13, which are used to utilize the rotational misalignment of the rotating tube 13 and the liquid inlet 12 to make the docking ports 131 and the liquid inlet channels 121 rotate and dock, and a sealing ring 17 is provided at the docking port 131 of the rotating tube 13.

[0050] The working principle of the above-mentioned groundwater monitoring and sampling integrated equipment is: a well is dug in advance in the area where groundwater sampling and monitoring is required, and the wellhead diameter is at least 30 cm larger than the equipment diameter, and then the groundwater monitoring and sampling integrated equipment is placed in the well, and the depth of groundwater collection is marked according to the depth of each liquid inlet 12 of the cylinder 1.

[0051] By rotating the threaded portion of the operating rod 3 to make it cooperate with the threaded carrier 4, the operating rod 3 is moved downward as a whole, and the position of the liquid inlet 12 of the cylinder 1 where each liquid collecting box 2 is currently located is determined according to the height of the threaded portion being rotated down and the distance between each liquid collecting box 2. When it moves to the required depth, the threaded portion of the operating rod 3 is stopped from rotating. It can be understood that a locking member can be provided on the threaded carrier 4 so that the threaded portion does not rotate at this time.

[0052] Then, the center rod 33 is rotated, and the gear ring 36 is driven to rotate by its rotation, so that the gears 35 of each first rotating block 34 are rotated, so that the second rotating block 22 and the transmission screw 23 of the liquid collecting box 2 are rotated under the linkage of the first rotating block 34 and the second rotating block 22. Under the action of the transmission screw 23 and the screw plate 26, the slide groove on the liquid guiding tube 25 cooperates with the limit block of the hole of the liquid collecting box 2, as shown in FIG. Fig. 9 As shown, the liquid guiding tube 25 cannot rotate but can only move horizontally, so the liquid guiding tube 25 moves horizontally outward. When the liquid guiding tube 25 is docked with the rotating tube 13, the thread on the liquid guiding tube 25 cooperates with the protrusion on the inner wall of the rotating tube 13, so that the rotating tube 13 rotates 30°, and then the docking port 131 of the rotating tube 13 is docked with the liquid inlet channel 121 of the liquid inlet 12. The groundwater flows through the rotating tube 13 and the liquid guiding tube 25 through the liquid inlet channel 121 and enters the liquid tank 24.

[0053] When the liquid tank 24 contains groundwater of this depth, the groundwater in the liquid tank 24 can be monitored by a commercially available monitoring instrument arranged on the top surface of the liquid collecting box 2, such as a commercially available pH tester. Not shown in the figure, the probe can be loaded and fixed on the top surface of the liquid collecting box 2 and extend into the liquid tank 24. Therefore, the device can be used to perform repeated downward exploration operations many times without affecting the water layer distribution of the groundwater, which not only reduces the labor intensity of the operators, but also improves the collection accuracy of water samples at different depths and the monitoring effect.

[0054] At the same time, the assembly method of the liquid collecting box 2 and the connecting portion 32 of the operating rod 3 is as follows: Figure 7 As shown, the center of the liquid collecting box 2 has a special-shaped circular hole for the control rod 3 to pass through, and the side wall of the special-shaped circular hole has a sink groove for the first rotating block 34 to pass through. When the liquid collecting box 2 moves to the connecting portion 32 at the required position height, the latches 5 on the top and bottom surfaces of the liquid collecting box 2 are inserted into the latch holes 321. At the same time, the first rotating block 34 and the I-shaped protrusions and I-shaped recesses of the second rotating block 22 complete the clamping connection, thereby realizing the assembly of the liquid collecting box 2 and the connecting portion 32 of the control rod 3; it should be noted that the arrangement positions of multiple liquid collecting boxes 2 can be distributed on the connecting portion 32 according to actual use requirements. Figure 3 What is shown is an equidistant arrangement, but the usage is not limited to this one.

[0055] Embodiment 2: This embodiment differs from Embodiment 1 in that Figure 1 As shown, a handle is provided at the upper end of the cylinder body 1, a rotating handle is provided at the upper end of the threaded portion 31 of the control rod 3, and a knob is provided at the upper end of the center rod 33.

[0056] The working principle of the above-mentioned integrated groundwater monitoring and sampling equipment is: based on the working principle of Example 1, the cylinder 1 can be placed in a pre-drilled wellhead through the handle, the rotation of the threaded part 31 can be controlled by turning the handle, and the rotation of the center rod 33 can be controlled by turning the ball. It can be understood that in order to improve the assembly stability of the center rod 33 and the control rod 3, the knob can be rotatably connected to the rotating handle.

[0057] Embodiment 3: This embodiment differs from Embodiment 1 in that Figure 2 , Fig.10 , Fig.11As shown, an airbag ball 14 is provided on the inner wall of the guide rail 11, and a locking block 15 for locking the rotation of the rotating tube 13 is provided in the liquid inlet 12. The airbag ball 14 is connected to the airbag assembly for driving the locking block 15 to descend through a pipeline, and a locking groove 132 cooperating with the locking block 15 is provided on the rotating tube 13, and guide slopes are provided on both sides of the locking groove 132. Specifically, the airbag assembly includes a wedge block 18 and an airbag strip 19, and a cavity is provided in the inner wall of the cylinder 1 at this location, and the wedge block 18 is slidably connected to the cavity, one end of the wedge block 18 is connected to the cavity through a spring, and the other end of the wedge block 18 is connected to the cavity through the airbag strip 19, and when in the locked state, the lower end of the locking block 15 is located at the highest point of the wedge block 18.

[0058] The working principle of the above-mentioned groundwater monitoring and sampling integrated device is as follows: based on the working principle of Example 1, when the slider 21 of the liquid collecting box 2 moves to the liquid inlet 12 at the specified position, the slider 21 will continue to squeeze the airbag ball 14 corresponding to the liquid inlet 12.

[0059] When the airbag ball 14 is squeezed, the airbag strip 19 connected thereto expands, thereby pushing the wedge block 18 toward Fig.11 The left side shown in the figure moves and compresses the spring. At this time, the locking block 15 descends under the action of its own gravity, so that the locking block 15 is out of the locked state with the locking groove 132.

[0060] When the liquid collecting box 2 leaves the liquid inlet 12, the airbag ball 14 is under its own restoring force. It can be understood that the material of the airbag ball 14 has self-restoring ability or it has a built-in spring to give it restoring force. The airbag strip 19 contracts, thereby resetting the wedge block 18 and resetting the locking block 15 to engage with the locking groove 132, thereby locking the rotating tube 13. Therefore, the locking block is controlled to be closed by the extrusion linkage of the slider and the airbag ball, so that the rotating tube in the current position can cooperate with the liquid guide tube to pass liquid, so as to avoid rotation deviation of other rotating tubes and the like, which may cause groundwater to flow into the cylinder 1 of the equipment.

[0061] Embodiment 4: This embodiment differs from Embodiment 1 in that Fig.12 , Fig.13 As shown, a conical baffle 16 for diverting groundwater is provided in the rotating tube 13 , the conical baffle 16 is fixedly connected to the rotating tube 13 , and the side surface of the conical baffle 16 has 6 diversion grooves arranged in a spiral manner.

[0062] The working principle of the above-mentioned integrated groundwater monitoring and sampling equipment is: based on the working principle of Example 1, when the water flows into the rotating tube 13 through the docking port 131, under the action of the various guide grooves of the conical partition 16, the groundwater flowing into the liquid guide tube 25 enters in a swirling manner, thereby accelerating the efficiency of groundwater flowing into the liquid tank 24.

[0063] Embodiment 5: This embodiment differs from Embodiment 1 in that Figure 2 , Fig.14 As shown, the threaded carrier 4 is detachably connected to the cylinder 1 through a buckle, and an insert block is provided at the lower end of the threaded carrier 4, and a slot assembled with the insert block is provided on the upper end surface of the cylinder, thereby further improving the stability of the threaded carrier 4. It can be understood that the buckle is a flip buckle with a rotating shaft, and the side of the threaded carrier 4 has a bayonet that cooperates with the buckle.

[0064] The working principle of the above-mentioned integrated groundwater monitoring and sampling equipment is: based on the working principle of Example 1, when disassembling and assembling the threaded carrier 4, the various plug-in blocks of the threaded carrier 4 are docked with the corresponding slots, and then the various buckles are rotated to make them snap into the corresponding snap-ons of the threaded carrier 4 to realize the loading of the threaded carrier 4. When the threaded carrier 4 needs to be disassembled, just repeat the above operation in reverse.
