Description

Technical Field

[0001] This utility model relates to the field of mining hydrological exploration technology, specifically to a foldable and retractable mining hydrological exploration sampling device. Background Technology

[0002] In the field of mine hydrogeological exploration, it is often necessary to collect water or sediment samples from boreholes or wells in order to assess the groundwater hydrogeological conditions of mining areas. These sampling devices usually need to have a certain depth penetration capability to meet the sampling needs at different depths. At the same time, given the complexity of the mining environment and the special nature of fieldwork, the portability, ease of operation, and reliability of the sampling devices become key considerations.

[0003] Currently, common mining hydrological exploration sampling devices typically employ segmented rods and support structures, with each component assembled via threaded connections. While this threaded connection-based assembly method ensures a certain level of structural strength, it presents significant problems in practical field applications. The assembly and disassembly process is cumbersome and time-consuming, requiring operators to repeatedly rotate each rod and support section, resulting in extremely low work efficiency. This is especially true when frequent changes in sampling points or multiple borehole sampling are required, with a significant amount of time wasted on assembling and disassembling the equipment.

[0029] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0030] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0031] Combination Figures 1-13 As shown, the foldable and retractable mining hydrological survey sampling device includes a hand crank 1, a drive unit, a support assembly, and a sampling unit.

[0032] The drive unit includes several drive rods that can be assembled into one unit, and these drive rods can be connected to the hand crank 1. Specifically, the drive rods are modularly designed, with each drive rod having the same structure. They are connected to the insertion slots 15 at the ends of adjacent drive rods or hand crank 1 via a plug-in block 18 at one end, thereby achieving rapid extension of the power transmission chain. This allows the operator to flexibly increase or decrease the number of drive rods according to the actual depth of the sampling hole, and assembly can be completed without the use of any tools, greatly improving the adaptability to field work.

[0033] The support assembly includes several sets of support units sleeved on the outside of the drive unit. Each set of support units includes an upper support sleeve 2, a lower support sleeve 3, and an intermediate connecting plate 7. The upper support sleeve 2 and the lower support sleeve 3 are rotatably mounted on both sides of the intermediate connecting plate 7, so that the support unit can be folded around the intermediate connecting plate 7 as an axis, thereby significantly reducing the overall volume when not in use. Limiting units are also provided on both sides of the intermediate connecting plate 7, which are used to fix the positions of the upper support sleeve 2 and the lower support sleeve 3 respectively. When the support sleeve is rotated to be in a straight line with the intermediate connecting plate 7, the limiting units can be automatically or manually locked to ensure the stability of the support state. The upper support sleeve 2 and the lower support sleeve 3 are respectively provided with a snap-fit ​​plate 4 on the side away from the intermediate connecting plate 7. The snap-fit ​​plate 4 on the upper support sleeve 2 has a connected slot 5 and a snap-fit ​​groove 6. The snap-fit ​​plate 4 on the lower support sleeve 3 has a connecting block 16 that is rotatably mounted in the slot 5 and snaps into the snap-fit ​​groove 6. Specifically, during assembly, the connecting block 16 of the upper support sleeve 2 of the lower support unit is aligned with the slot 5 on the snap plate 4 of the lower support sleeve 3 of the upper support unit. After insertion, it is rotated at a certain angle so that the connecting block 16 slides in and is snapped into the snap groove 6, thus achieving a quick and stable connection between the upper and lower support units without the need for screwing.

[0034] The sampling unit includes a sampling barrel 12, with a sampling port on the side wall of the sampling barrel 12 for allowing water to enter the target water layer. A switch plate 13 is rotatably mounted on the inner wall of the sampling barrel 12, and a sealing element, such as a rubber sealing ring, is provided between the switch plate 13 and the sampling barrel 12 to ensure the sealing of the sampling port when the switch plate 13 is closed. A connecting sleeve 14 is provided at the top of the sampling barrel 12, and a snap-fit ​​plate 4 is provided at the top of the connecting sleeve 14. The snap-fit ​​plate 4 has a slot 5 and a snap-fit ​​groove 6 that cooperate with the connecting block 16 for quick snap-fit ​​with the bottom support unit. The rotating shaft of the switch plate 13 is rotatably mounted on the top wall of the sampling barrel 12, and a plug-in block 18 is provided on the rotating shaft that can be plugged into and cooperate with the drive unit and / or the hand crank 1. When the drive unit or the hand crank 1 is lowered and connected to the plug-in block 18, the opening and closing state of the switch plate 13 can be controlled by rotation.

[0035] In one embodiment of this utility model, such as Figure 2As shown, a plug-in groove 15 is provided on one end face of the hand crank 1, which can be plugged into the plug-in block 18. Specifically, the shape of the plug-in groove 15 is consistent with the plug-in groove 15 at the end of the drive rod, so that the hand crank 1 can be used as an initial power source connected to the drive unit, or it can be directly connected to the plug-in block 18 on the sampling unit shaft when the sampling unit needs to be operated separately, thus realizing the versatility of functions.

[0036] In one embodiment of this utility model, such as Figures 10-13 As shown, the drive rod includes a rod body 20, with a connector block 18 at one end and a connector slot 15 at the other end. The rod body 20 is hollow inside. Specifically, the hollow rod body 20 effectively reduces the overall weight of the drive unit while ensuring sufficient structural strength, reducing the operator's workload and making it easier to carry in the field. The connector block 18 and connector slot 15 have non-circular cross-sections, such as square or hexagonal, to ensure reliable torque transmission after insertion.

[0037] In one embodiment of this utility model, magnetic blocks 19 are embedded on both the end face of the plug-in block 18 and the inner end face of the plug-in groove 15. Specifically, the magnetic blocks 19 are made of strong magnetic materials, such as neodymium iron boron. When the plug-in block 18 is inserted into the plug-in groove 15, the magnetic blocks 19 at both ends attract each other, generating a pre-tightening force. This pre-tightening force not only ensures the stability of the plug-in connection and prevents accidental disengagement during lifting or vibration, but also provides a clear feel for the connection during the docking process, assisting the operator to quickly complete the connection.

[0038] In one embodiment of this utility model, such as Figure 6 As shown, guide members 17 are also provided on the inner walls of the upper support sleeve 2 and the lower support sleeve 3, so that the drive rod is coaxially arranged with the upper support sleeve 2 and the lower support sleeve 3. Specifically, the guide member 17 is an annular bushing fixed to the inner wall of the support sleeve or at least three guide wheels evenly distributed in a circle. The inner diameter of the guide member 17 matches the outer diameter of the drive rod. Its function is to constrain the drive rod, so that it rotates at the center position of the support sleeve, avoids friction or collision between the drive rod and the inner wall of the support sleeve, ensures smooth rotation, reduces operating resistance, and improves the stability of the entire structure.

[0039] In one embodiment of this utility model, such as Figure 3As shown, the limiting unit includes limiting holes respectively opened on the side walls of the upper support sleeve 2 and the lower support sleeve 3, and a U-shaped frame 8 set on the intermediate connecting plate 7. A limiting rod 9, which passes through the intermediate connecting plate 7 and can be inserted into the limiting hole, is slidably mounted on the U-shaped frame 8. A limiting plate 11 is provided on the limiting rod 9, and a spring 10 is sleeved on the limiting rod 9 and set between the limiting plate 11 and the U-shaped frame 8. Specifically, when the upper support sleeve 2 or the lower support sleeve 3 rotates relative to the intermediate connecting plate 7 to the fully unfolded state, the limiting hole on its side wall is exactly aligned with the limiting rod 9. Under the elastic force of the spring 10, the limiting rod 9 will automatically pop out and insert into the limiting hole, thereby locking the support sleeve in the unfolded position and preventing it from folding accidentally during operation. When it needs to be folded and stored, the operator only needs to manually pull the limiting rod 9 outward to overcome the force of the spring 10 and make it exit the limiting hole, and then rotate the support sleeve to fold it. This structure is simple to operate and has reliable locking.

[0040] A foldable and retractable mining hydrological exploration and sampling device according to an embodiment of the present invention.

[0041] When using it, the device must first be assembled:

[0042] Unfold the support units in their folded states so that the upper and lower support sleeves 3 and the middle connecting plate 7 are aligned. At this time, the limiting unit automatically pushes the limiting rod 9 into the limiting hole of the support sleeve under the action of the spring 10 to achieve locking. Through the cooperation of the connecting block 16 on the snap-fit ​​plate 4 with the L-shaped slot 5 and the snap-fit ​​groove 6, multiple support units are quickly snapped and connected from top to bottom to form a stable vertical support channel. According to the sampling depth, the required number of drive rods are quickly connected in sequence through the plug-in block 18 and the plug-in groove 15. The assembled drive unit is inserted into the connected support assembly from the top. The sampling unit is snapped into the lower support sleeve 3 of the bottom support unit through the snap-fit ​​plate 4 at its top. Finally, the plug-in groove 15 at the bottom of the drive unit is plugged into the plug-in block 18 on the rotating shaft of the sampling unit switch plate 13. The plug-in groove 15 of the hand crank 1 is connected to the plug-in block 18 of the top drive rod.

[0043] Rotating the drive unit with the hand crank 1 initially puts the switch plate 13 inside the sampling tank 12 in the closed position, sealing the sampling port. Then, the entire device is slowly lowered into the target water layer in the borehole. Continuing to rotate the drive unit with the hand crank 1 transmits power to the shaft of the switch plate 13, causing the switch plate 13 to rotate and thus opening the sampling port. Water begins to enter the sampling tank 12. Once the sampling tank 12 is full of water sample, the hand crank 1 is rotated in the opposite direction to drive the switch plate 13 to rotate back until it completely closes the sampling port. The seal ensures a tight seal. At this point, the device can be lifted out of the borehole. After lifting the device to the ground, the hand crank 1, drive unit, and support assembly can be quickly disassembled. Finally, the sampling unit is removed, and the sampling tank 12 is opened to obtain the required water sample.

[0044] After disassembly, for the support unit, pull the limiting rod 9 to disengage it from the limiting hole, and the upper and lower support sleeves 3 can be folded towards the middle. The drive rod can be stored separately, and all components can be compactly stored, which greatly facilitates transportation and storage.

[0045] This invention replaces the inefficient threaded connection with a quick-connect method that combines plug-in, snap-in and magnetic attraction. Through a foldable support structure and modular drive rod, it achieves overall lightweight and portability of the device. And through reliable limiting and sealing design, it ensures the stability of the sampling process and the authenticity of the sample.

[0046] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
