Description

Technical Field

[0001] The present invention relates to the technical field of groundwater sampling and monitoring, and specifically relates to an integrated device for groundwater monitoring and sampling used in hydrogeological exploration. Background Art

[0002] In hydrogeological exploration, groundwater sampling and monitoring play a crucial 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, industrial water use, etc.

[0003] Moreover, by regularly 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 promptly detect groundwater anomalies and provide valuable time for disaster warning and emergency response.

[0004] Currently, when monitoring groundwater, operators often use simple sampling devices such as buckets for sampling and monitoring work. However, these devices can only obtain samples at a certain depth each time, and are more likely to affect the water layer distribution of groundwater during repeated lowering multiple times. This not only increases the labor intensity of the operators, but also easily affects the collection accuracy of water samples at different depths and the monitoring effect. In view of this, an integrated device capable of sampling and monitoring groundwater at multiple depth points is proposed to solve the above problems. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides an integrated device for groundwater monitoring and sampling used in hydrogeological exploration.

[0006] The technical solution of the present invention is: an integrated device for groundwater monitoring and sampling used in hydrogeological exploration, including a cylinder body, a plurality of liquid collection boxes slidably arranged in the cylinder body, and a control rod for connecting each of the liquid collection boxes;

[0007] A guide rail for the up and down movement of the liquid collection box is provided on the inner wall of the cylinder body, and a slider slidably connected to the guide rail is provided on the side wall of the liquid collection box.

[0008] The top surface of the cylinder body is provided with a threaded carrier plate. The control rod is composed of a threaded part for rotatably connecting with the threaded carrier plate and a connecting part for fixing the liquid collecting box, which are connected up and down. Both the threaded part and the connecting part are hollow rod bodies, and a central rod is rotatably arranged inside the control rod. The connecting part is provided with a first rotating clamping block for docking with the liquid collecting box. A toothed ring meshing and driving with a gear provided at the inner end of the first rotating clamping block is arranged on the central rod. A second rotating clamping block is arranged on the side wall of the through hole of the liquid collecting box, and a transmission screw rod is arranged at the inner end of the second rotating clamping block. The first rotating clamping block and the second rotating clamping block are slidably clamped. A liquid storage chamber corresponding to each second rotating clamping block is arranged inside the liquid collecting box. A liquid guiding pipe is arranged on the side wall of the liquid collecting box corresponding to each liquid storage chamber and is in limit sliding and sealing connection with it. The transmission screw rod is in threaded connection with a screw disc arranged at the inner end of the liquid guiding pipe for pushing the liquid guiding pipe to move outward.

[0009] A plurality of liquid inlet ports are arranged on the inner wall of the cylinder body located in the guide rail from top to bottom. A rotating pipe is rotatably and sealingly connected inside the liquid inlet port. One end of the liquid guiding pipe is in threaded connection with the pipe hole of the rotating pipe. A plurality of liquid inlet channels are arranged on the liquid inlet port, and a plurality of docking ports are arranged on the side wall of the rotating pipe and are arranged in a staggered manner with the liquid inlet channels for rotatably docking the docking ports with the liquid inlet channels by rotating the rotating pipe and the liquid inlet port out of alignment.

[0010] Furthermore, a plurality of pin holes are arranged on the side surface of the connecting part from top to bottom in sequence, and pins for plugging and fixing with the pin holes of the connecting part are arranged on the upper and lower end surfaces of the liquid collecting box. The pin holes are arranged according to the positions of the scale graduations.

[0011] Explanation: By setting the pin holes according to the scale graduations, for example, setting a group of pin holes for placing the liquid collecting box every 30 cm, the vertical interval distance between two liquid collecting boxes can be more easily controlled. Thus, a plurality of liquid collecting boxes can be placed on the connecting part according to different vertical interval distances according to actual needs to meet the sampling and monitoring work of groundwater at different depths simultaneously.

[0012] Furthermore, a linear protrusion is arranged at the outer end of the first rotating clamping block, and a linear concave block for mating with the linear protrusion is arranged at the outer end of the second rotating clamping block. Both the linear protrusion and the linear concave block are coated with a magnetic coating.

[0013] Explanation: Adopting the clamping and driving mode of the linear protrusion and the linear concave block facilitates the up and down sliding of the liquid collecting box from the connecting part of the control rod to quickly adjust the vertical height position of the liquid collecting box. And the driving mode is reliable, which can effectively realize the synchronous rotation of the first rotating clamping block and the second rotating clamping block. At the same time, the connection strength between the two can be further strengthened through the magnetic coating, thereby improving the stability of the transmission at this place.

[0014] Further, airbag balls are provided on the inner wall of the guide rail, a locking block for locking the rotation of the rotating pipe is provided in the liquid inlet, the airbag balls are connected to an airbag assembly for driving the locking block to descend through a pipeline, and a locking groove cooperating with the locking block is provided on the rotating pipe, and guide slopes are provided on both sides of the locking groove.

[0015] Explanation: Through the settings of the airbag balls and the locking block, the closing of the locking block can be controlled by the extrusion linkage between the slider and the airbag balls, so that the rotating pipe at the current position can cooperate with the liquid guide pipe for liquid conduction, avoiding the situation that other rotating pipes rotate and shift, resulting in groundwater flowing into the equipment.

[0016] Further, a handle is provided at the upper end of the cylinder body, a rotating handle is provided at the upper end of the threaded part of the control rod, and a knob is provided at the upper end of the central rod.

[0017] Explanation: Through the setting of the handle, it is convenient to control the cylinder body to descend. Through the settings of the rotating handle and the knob, the threaded part and the central rod of the control rod can be controlled, thereby realizing the descending operation of the control rod and the rotating operation of the central rod.

[0018] Further, a conical partition for guiding the flow of groundwater is provided in the rotating pipe, the conical partition is fixedly connected to the rotating pipe, and a plurality of flow guiding grooves arranged in a spiral manner are provided on the side surface of the conical partition.

[0019] Explanation: Through the settings of the conical partition and the flow guiding grooves, the flow efficiency of groundwater can be enhanced, enabling the groundwater to enter the liquid guide pipe in a swirling manner, thereby improving the liquid guiding effect and enhancing the operation efficiency of the equipment.

[0020] Further, a sealing ring is provided at the docking port of the rotating pipe.

[0021] Explanation: Through the setting of the sealing ring, the docking between the rotating pipe and the liquid inlet can be enhanced, avoiding incomplete sealing between the rotating pipe and the liquid inlet channel, resulting in a reduction in the groundwater guiding effect and affecting the groundwater sampling and monitoring effect of the equipment.

[0022] Further, the threaded carrier plate is detachably connected to the cylinder body through a buckle.

[0023] Explanation: By adopting the detachable method of the buckle, the installation and connection operation of the threaded carrier plate can be carried out quickly, facilitating the overall removal of the control rod and the liquid collection box for position adjustment of the liquid collection box, etc.

[0024] The beneficial effects of the present invention are:

[0025] (1) The integrated groundwater monitoring and sampling device of the present invention can perform multiple repeated downward probing operations without affecting the water layer distribution of groundwater. This not only reduces the labor intensity of operators but also improves the collection accuracy of water samples at different depths and the monitoring effect, providing a new method for groundwater monitoring and sampling.

[0026] (2) The integrated groundwater monitoring and sampling device of the present invention uses a cylinder as the external wall of the device to keep its interior water-free. Then, through the cooperation of the control rod and the liquid collection box, it probes downward to a specified position in the cylinder for sampling operations. The outside of the liquid collection box is always in a relatively dry state, so monitoring equipment can be carried on it for groundwater monitoring without the risk of the monitoring equipment being immersed in groundwater.

[0027] (3) The integrated groundwater monitoring and sampling device of the present invention largely adopts a modular setting and can be flexibly adjusted according to the specific requirements of groundwater monitoring and sampling. For example, according to actual needs, the connection parts of multiple liquid collection boxes on the control rod can be adjusted to be equally spaced or have various spacing distributions, making the device convenient and efficient for monitoring and sampling groundwater at different depths.

Specific embodiments

[0043] The following further details the present invention in combination with specific embodiments to better reflect the advantages of the present invention.

[0044] Embodiment 1: An integrated device for groundwater monitoring and sampling used in hydrogeological exploration, as Figure 1 shown, including a cylinder body 1, a plurality of liquid collecting boxes 2 slidably arranged in the cylinder body 1, and a control rod 3 for connecting each of the liquid collecting boxes 2. The cross-section of the cylinder body 1 is a regular hexagon;

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

[0046] As Figure 1 shown, a threaded carrier plate 4 is provided on the top surface of the cylinder body 1. As Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the joystick 3 is composed of a threaded portion 31 that is rotatably connected up and down and is used to connect to the threaded carrier plate 4, and a connecting portion 32 that is used to fix the liquid collecting box 2. The threaded portion 31 and the connecting portion 32 are rotatably and vertically limitedly connected through an annular slot and a snap ring. Both the threaded portion 31 and the connecting portion 32 are hollow rod bodies, and a central rod 33 is rotatably arranged inside the joystick 3. The connecting portion 32 is provided with six first rotating blocks 34 in a group for docking with the liquid collecting box 2, and they are distributed at an angular interval of 60°. A toothed ring 36 that meshes and drives with a gear 35 provided at the inner end of the first rotating block 34 is provided on the central rod 33, as Figure 5 As shown, an annular sunk groove is provided on the inner wall of the connecting portion 32 at a position corresponding to the toothed ring 36 to satisfy the meshing and driving of the toothed ring 36 and the gear 35. A second rotating block 22 is provided on the side wall of the through hole of the liquid collecting box 2, and a transmission screw 23 is provided at the inner end of the second rotating block 22. The first rotating block 34 and the second rotating block 22 are slidably and snap-connected. Specifically, a flat protrusion is provided at the outer end of the first rotating block 34, and a flat concave block for mating with the flat protrusion is provided at the outer end of the second rotating block 22, and both the flat protrusion and the flat concave block are coated with a magnetic coating. The magnetic coating is a commercially available magnetic coating,

[0047] As Figure 7 、 Figure 8 shown, a liquid storage chamber 24 corresponding to the second rotating block 22 one by one is provided in the liquid collecting box 2. A liquid guide pipe 25 that is limitedly, slidably and sealingly connected to the side wall of the liquid collecting box 2 corresponding to each liquid storage chamber 24 is provided. The transmission screw 23 is threadedly connected to a screw disk 26 provided at the inner end of the liquid guide pipe 25 for pushing the liquid guide pipe 25 to move outward,

[0048] As Figure 5 shown, a plurality of pin holes 321 are sequentially provided on the side surface of the connecting portion 32 from top to bottom, and pins 5 for plugging and fixing with the pin holes 321 of the connecting portion 32 are provided on both the upper and lower end surfaces of the liquid collecting box 2. The pin holes 321 are arranged according to the positions of the scale graduations. For example, a set of pin holes is provided every 30 cm in the vertical height,

[0049] As Figure 2 shown, thirteen liquid inlet ports 12 are provided on the inner walls of six sides of the cylinder body 1 located in the guide rail 11 from top to bottom. For example, the distance between two adjacent liquid inlet ports 12 is 30 cm. A rotating pipe 13 that is rotatably and sealingly connected to the liquid inlet port 12 is provided in the liquid inlet port 12, as Figure 9 、 Figure 10 shown, one end of the liquid guide pipe 25 is threadedly connected to the pipe hole of the rotating pipe 13. Specifically, as Figure 10 、 Figure 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. Figure 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 groundwater of this depth accumulates in the liquid storage tank 24, it can be monitored through a commercially available monitor, such as a commercially available pH detector, etc., arranged on the top surface of the liquid collection box 2. Although not shown in the figure, it can be loaded and fixed on the top surface of the liquid collection box 2 with the probe extending into the liquid storage tank 24. Therefore, with this device, multiple repeated downward probing operations can be carried out without affecting the water layer distribution of the groundwater, which not only reduces the labor intensity of the operator but also improves the collection accuracy and monitoring effect of water samples at different depths.

[0054] Meanwhile, the assembly method of the connecting part 32 between the liquid collection box 2 and the control rod 3 is as follows: Figure 7 As shown, the center of the liquid collection box 2 has a special-shaped round hole for the control rod 3 to pass through. The side wall of the special-shaped round hole has a sunk groove for the first rotating clamping block 34 to pass through. When the liquid collection box 2 moves to the connecting part 32 at the required position height, the pins 5 on the top and bottom surfaces of the liquid collection box 2 are inserted into the pin holes 321. At the same time, the first rotating clamping block 34 and the linear protrusions and linear recesses of the second rotating clamping block 22 are clamped, thus realizing the assembly of the connecting part 32 between the liquid collection box 2 and the control rod 3; it should be noted that the arrangement positions of multiple liquid collection boxes 2 can be distributed on the connecting part 32 according to actual usage requirements. Figure 3 As shown, it is an equally spaced arrangement method, but it is not limited to this usage method only.

[0055] Embodiment 2: The difference between this embodiment and Embodiment 1 is that, as Figure 1 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 part 31 of the control rod 3, and a knob is provided at the upper end of the central rod 33.

[0056] The working principle of the above integrated groundwater monitoring and sampling device is as follows: On the basis of the working principle of Embodiment 1, the cylinder body 1 can be placed in a pre-drilled well opening through the handle. By rotating the handle to control the rotation of the threaded part 31 and rotating the central rod 33 by rotating the ball, it can be understood that in order to improve the assembly stability between the central rod 33 and the control rod 3, the knob can be rotatably connected to the rotating handle.

[0057] Embodiment 3: The difference between this embodiment and Embodiment 1 is that, as Figure 2 、 Figure 10 、 Figure 11As shown, an airbag ball 14 is provided on the inner wall of the guide rail 11. A locking block 15 for locking the rotation of the rotating pipe 13 is provided in the liquid inlet 12. The airbag ball 14 is connected to an airbag assembly for driving the locking block 15 to descend through a pipeline. A locking groove 132 cooperating with the locking block 15 is provided on the rotating pipe 13. 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. There is a cavity in the inner wall of the cylinder 1 at this location. 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. 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 groundwater monitoring and sampling integrated device is as follows: On the basis of the working principle of Embodiment 1, when the slider 21 of the liquid collection box 2 moves to the liquid inlet 12 at the specified position, at this time, the slider 21 will continuously squeeze the airbag ball 14 corresponding to the liquid inlet 12.

[0059] After the airbag ball 14 is squeezed, the airbag strip 19 communicated with it expands, thereby pushing the wedge block 18 Figure 11 to move to the left as shown and squeeze the spring. At this time, the locking block 15 descends under its own gravity, so that the locking block 15 is disengaged from the locked state with the locking groove 132.

[0060] When the liquid collection 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 a spring is built in it to make it have a restoring force. The airbag strip 19 contracts, so that the wedge block 18 is reset to push the locking block 15 up and reset to engage with the locking groove 132, thereby locking the rotating pipe 13. Therefore, it is realized to use the extrusion linkage of the slider and the airbag ball to control the locking block to close, so that the rotating pipe at the current position can cooperate with the liquid guide pipe to conduct liquid, so as to avoid the situation that other rotating pipes rotate and shift, etc., causing groundwater to pour into the cylinder 1 of the device.

[0061] Embodiment 4: The difference between this embodiment and Embodiment 1 is that, as Figure 12 、 Figure 13 shown, a conical partition 16 for guiding groundwater is provided in the rotating pipe 13. The conical partition 16 is fixedly connected to the rotating pipe 13, and there are 6 diversion grooves arranged in a spiral manner on the side surface of the conical partition 16.

[0062] The working principle of the above groundwater monitoring and sampling integrated device is as follows: On the basis of the working principle of Embodiment 1, when water flows through the butting joint 131 into the rotating pipe 13, under the action of each diversion groove of the conical partition 16, the groundwater flowing into the liquid guide pipe 25 enters in a swirling manner, thereby accelerating the efficiency of groundwater pouring into the liquid storage bin 24.

[0063] Example 5: The difference between this example and Example 1 is that, as Figure 2 , Figure 14 shown, the threaded carrier 4 is detachably connected to the cylinder body 1 through a buckle, and an insertion block is provided at the lower end of the threaded carrier 4, and a slot for assembling with the insertion block is provided on the upper end surface of the cylinder body, so as to further improve the stability of the threaded carrier 4. It can be understood that the buckle is a flip-type buckle with a rotating shaft, and a bayonet for cooperating with the buckle is provided on the side surface of the threaded carrier 4.

[0064] The working principle of the above groundwater monitoring and sampling integrated device is as follows: On the basis of the working principle of Example 1, when disassembling and assembling the threaded carrier 4, dock the insertion blocks of the threaded carrier 4 with the corresponding slots, and then rotate each buckle so that it snaps into the corresponding bayonet of the threaded carrier 4 to realize the loading of the threaded carrier 4. When it is necessary to disassemble the threaded carrier 4, just repeat the above operations in reverse.
