Description

Technical Field

[0001] This utility model relates to the field of soil and water conservation testing and sampling technology, and more specifically, it relates to a sampling device for soil and water conservation testing. Background Technology

[0002] Sampling devices for soil and water conservation testing typically separate water and soil storage chambers using filter plates for sampling. However, in existing technologies, when it is necessary to disassemble or assemble the water and soil storage chambers, specialized tools are usually required, which is time-consuming and labor-intensive. Furthermore, incompatible tool models or incomplete tool sets may prevent disassembly or assembly. Specifically, the traditional connection method of sampling devices for soil and water conservation testing often requires the use of various sizes of specialized tools such as screwdrivers, wrenches, and special disassembly tools to complete the disassembly and assembly operations. In actual field soil and water conservation testing work, testing personnel need to carry a large number of specialized equipment and instruments. If additional disassembly and assembly tools are also required, it not only increases the burden of fieldwork but also makes it easy for the sampling device to malfunction due to tool omissions or damage. This is especially true for soil and water conservation testing work conducted in complex terrain conditions and in harsh weather environments, such as steep mountain slopes, river valley wetlands, or muddy areas after heavy rain. Testing personnel often need to travel long distances on foot, and carrying too many tools will seriously affect their mobility and work efficiency. Utility Model Content

[0006] The present invention is further configured such that an inlet groove is provided on the side wall of the cylinder, a soil storage chamber is provided on the inner side of the cylinder, and a water storage chamber is provided on the inner side of the conical head.

[0007] The present invention is further configured such that a filter frame is provided between the water storage tank and the soil storage tank, and the outer wall of the filter frame is movably connected to the inner wall of the soil storage tank by threads.

[0011] The present invention is further provided with an anti-slip strip on the outer side of the control sleeve.

[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides a sampling device for soil and water conservation testing, which has the following beneficial effects: 1. Through the ingenious coordination of components such as a cylinder, conical head, locking rod, connecting cover, locking sleeve, control sleeve, linkage block, fixing block, linkage spring, top block, moving sleeve, push block, push spring, mating groove, mating block, and locking frame, this device effectively solves the technical problem of requiring specialized tools for disassembling and assembling water and soil storage tanks in existing technologies. This device adopts an innovative locking mechanism design, relying on the rotation mechanism of the control sleeve and linkage block, combined with the elastic limiting structure of the linkage spring and fixing block, achieving a technological breakthrough in disassembly and assembly operations without any tools. In particular, the inclined structure design of the top block and push block, combined with the sliding mechanism of the push spring and moving sleeve, allows operators to simply rotate the control sleeve to loosen or lock the entire locking system, greatly improving efficiency. The simplified disassembly and assembly process of the water and soil storage tanks is particularly important in field soil and water conservation monitoring. Monitoring personnel no longer need to carry additional screwdrivers, wrenches, or specialized disassembly tools of various sizes, significantly reducing the burden on field workers and avoiding the risk of sampling devices malfunctioning due to lost or damaged tools. Furthermore, the chamfered structure of the mating groove and mating block ensures smoothness and reliability in the disassembly and assembly process. Even in complex terrain and harsh weather conditions, such as steep mountain slopes, river valley wetlands, or muddy areas after heavy rain, monitoring personnel can easily disassemble and assemble the equipment without being limited by tools, effectively improving the mobility and efficiency of field monitoring.

[0013] 2. Through a meticulously designed locking mechanism and guiding system, tool-free operation is achieved, ensuring the stability and reliability of the assembly and disassembly process. The precise alignment design of the guide rail and mating block, the sliding fit structure of the linkage rod and linkage hole, and the elastic connection mechanism of the mating spring and locking sleeve together constitute a complete self-guiding and self-locking system. In particular, the locking design between the locking frame and the locking groove, through the synchronous action of multiple mating springs, achieves a firm fixation of the locking frame to the locking rod, ensuring the stability of the connection between the water storage tank and the soil storage tank. The anti-slip strip on the outside of the control sleeve further improves the convenience and safety of operation, allowing testing personnel to control the assembly and disassembly process even with wet hands or wearing gloves. The spiral plate design on the outside of the cylinder and conical head not only facilitates the equipment's downward pressure into the soil, but also... The rotating mechanism of the handle and connecting cover provides excellent operating feel and torque transmission. Furthermore, when reassembly is required, the chamfered structure of the inner wall of the mating slot and the outer wall of the mating block allows the mating block to automatically align and insert into the locking slot under the push of the moving sleeve, significantly reducing assembly difficulty and time costs. This disassembly and assembly design ensures that even in large-scale soil and water conservation monitoring projects, monitoring personnel can quickly complete sampling at multiple monitoring points, preventing delays in valuable monitoring opportunities or affecting the accuracy of sampling data due to equipment disassembly and assembly issues. Simultaneously, the threaded connection design between the filter frame and the inner wall of the soil storage chamber facilitates cleaning or replacement of the filter frame, further improving the maintainability and service life of the equipment, and providing more reliable and efficient technical support for soil and water conservation research and engineering practice.

[0019] Please see Figures 1-5 A sampling device for soil and water conservation testing includes a cylinder 1, a conical head 2 on one side of the cylinder 1, a locking rod 3 connected to one side of the conical head 2, a detachable connecting cover 4 at the top of the cylinder 1, a detachable locking sleeve 5 on the outside of the locking rod 3, the locking sleeve 5 being disposed on one side of the connecting cover 4, a control sleeve 6 rotatably mounted on the outside of the locking sleeve 5, a linkage block 7 connected to one side of the control sleeve 6, a fixing block 8 fixedly mounted on the outside of the locking sleeve 5, a linkage spring 9 connecting the linkage block 7 and the fixing block 8, a top block 10 fixedly mounted on the outside of the control sleeve 6, and a movable sleeve 11 slidably mounted on the outside of the locking sleeve 5. A push block 12 is fixedly provided on the outside of the movable sleeve 11. Both the push block 12 and the top block 10 are designed with an inclined structure. A push spring 13 is movably sleeved on the outside of the locking sleeve 5. The two ends of the push spring 13 are connected to the movable sleeve 11 and the locking sleeve 5 respectively. A mating groove 14 is opened on the inside of the movable sleeve 11. A mating block 15 is movably provided in the mating groove 14. A locking frame 16 is connected to one side of the mating block 15. A locking groove 17 is opened on the outside of the locking rod 3. One end of the locking frame 16 passes through the locking sleeve 5 and is locked into the locking groove 17. The inner wall of the mating groove 14 and the outer wall of the mating block 15 are both designed with a chamfered structure.

[0020] A spiral plate 18 is fixedly provided on the outside of the cylinder 1 and the conical head 2, and a handle 19 is fixedly provided on the outside of the connecting cover 4.

[0021] The cylinder 1 has an inlet groove 20 on its side wall, a soil storage chamber 21 on its inner side, and a water storage chamber 22 on its inner side. A filter frame 23 is provided between the water storage tank 22 and the soil storage tank 21. The outer wall of the filter frame 23 is movably connected to the inner wall of the soil storage tank 21 by threads.

[0022] In this embodiment, when the device is needed, it is first assembled, then the conical head 2 is aligned with the sampling location. The connecting cover 4 can be rotated via the handle 19, thereby rotating the cylinder 1 and the conical head 2, which in turn moves the spiral plate 18 and presses the device down, causing the conical head 2, cylinder 1, and spiral plate 18 to gradually enter the soil. Some soil carrying groundwater enters the internal soil storage chamber 21 from the inlet trough 20. Due to the downward force, the water flows downward and passes through the filter frame 23 into the lower water storage chamber 22. After sampling, the device can be removed from the soil by reversing the operation. When the water storage chamber 22 and soil storage chamber 21 need to be separated after sampling, the control sleeve 6 is first rotated forward. The control sleeve 6 will drive the linkage block 7 on one side to rotate forward. Then, the linkage block 7 will drive the linkage rod 25 on one side to rotate forward along the linkage hole 26. The linkage block 7 will cooperate with the fixed block 8 to compress the linkage spring 9. Simultaneously, the control sleeve 6 will... The outer top block 10 rotates clockwise. Due to the special structural design of the top block 10 and the push block 12, when the top block 10 rotates clockwise, the push spring 13 resets and pushes the moving sleeve 11, causing the moving sleeve 11 to gradually slide along the guide rail 24. The moving sleeve 11 also drives the push block 12 to move, so that one side of the push block 12 is always in close contact with the top block 10. When the linkage spring 9 is squeezed to its limit, the control sleeve 6 cannot rotate, and at this time, the inner mating groove 14 of the moving sleeve 11 no longer restricts the outer wall of the mating block 15. Then, multiple cooperating springs 27 synchronously reset and push the cooperating block 15, causing the cooperating block 15 to drive one side of the locking frame 16 to move outward. Then, one end of the locking frame 16 will gradually slide out of the locking groove 17, and then the locking sleeve 5 will be pulled to one side to separate the locking sleeve 5 and the locking rod 3. Then, refer to the above steps to separate the other locking sleeves 5 and locking rods 3. Then, the conical head 2 and the cylinder 1 can be separated, thereby realizing the separation of the water storage tank 22 and the soil storage tank 21.

[0023] Please see Figures 3-5 As a further implementation of the overall equipment: a guide rail 24 is fixedly provided on the outside of the clamping sleeve 5, the guide rail 24 is aligned with the mating block 15, and the guide rail 24 is located in the mating groove 14.

[0024] A linkage rod 25 is connected to one side of the linkage block 7, and a linkage spring 9 is movably sleeved on the outside of the linkage rod 25. A linkage hole 26 is opened in the fixing block 8, and the other end of the linkage rod 25 is slidably inserted into the linkage hole 26.

[0025] Multiple mating springs 27 are connected to one side of the mating block 15, and the other end of the mating spring 27 is connected to the outer wall of the retaining sleeve 5.

[0026] The outer side of the control sleeve 6 is provided with anti-slip strips 28.

[0027] More specifically, when it is necessary to reassemble the water storage tank 22 and the soil storage tank 21 together, firstly, connect the water storage tank 22 and the soil storage tank 21 together, so that multiple locking rods 3 set on one side of the water storage tank 22 pass through the soil storage tank 21 and the connecting cover 4, and connect the outer spiral plate 18 of the cylindrical head and the outer spiral plate 18 of the cylinder 1 together, so that the spiral plates 18 are continuous. Then, the locking sleeve 5 is fitted from the connecting cover 4 to the outside of the locking rod 3. Then, the control sleeve 6 is released, and the linkage spring 9 resets and pushes the linkage block 7 to rotate in the opposite direction to reset. The linkage block 7 will drive the linkage rod 25 on one side to rotate in the opposite direction to reset along the linkage hole 26. At the same time, the linkage block 7 will drive the control sleeve 6 on one side to rotate in the opposite direction to reset, so that the control sleeve 6 drives the outer top block 10 to rotate in the opposite direction to reset. Then, the top block 10 pushes the push block 12 to one side, so that the push block 12 slides to reset. Then, push block 12 drives movable sleeve 11 to slide and reset along guide rail 24, and movable sleeve 11 drives inner mating groove 14 to slide and reset. Due to the chamfer design of one side of inner wall of mating groove 14 and one side of outer wall of mating block 15, the inner wall of mating groove 14 gradually presses mating block 15 inward, so that mating block 15 moves inward and resets. Mating block 15 will squeeze mating spring 27 on one side, so that mating block 15 drives one side locking bracket 16 to gradually lock into locking groove 17. At the same time, movable sleeve 11 will squeeze push spring 13. When linkage spring 9 is fully reset, control sleeve 6 is fully reset, and one end of locking bracket 16 is reinserted into locking groove 17 to form a locking relationship. Then, the other locking sleeves 5 are locked in accordance with the above steps to achieve convenient connection and convenient assembly and fixing of water storage tank 22 and soil storage tank 21.

[0028] In summary, when using or operating the overall equipment: First, assemble the equipment. Then, align the conical head 2 with the sampling location. Rotate the connecting cover 4 via the handle 19 to rotate the cylinder 1 and conical head 2, thereby moving the spiral plate 18 and pressing the equipment down. This causes the conical head 2, cylinder 1, and spiral plate 18 to gradually enter the soil. Some soil carrying groundwater enters the internal soil storage chamber 21 from the inlet trough 20. Due to the downward force, the water flows downward and passes through the filter frame 23 into the lower water storage chamber 22. After sampling, the equipment can be removed from the soil by reversing the operation. When separating the water storage chamber 22 and the soil storage chamber 21 after sampling, first rotate the control sleeve 6 forward. The control sleeve 6 will drive the linkage block 7 on one side to rotate forward. Then, the linkage block 7 will drive the linkage rod 25 on one side to rotate forward along the linkage hole 26. The linkage block 7 will cooperate with the fixed block 8 to compress the linkage spring 9. The control sleeve 6 drives the outer top block 10 to rotate clockwise. Due to the special structural design of the top block 10 and the push block 12, when the top block 10 rotates clockwise, the push spring 13 resets and pushes the moving sleeve 11, causing the moving sleeve 11 to gradually slide along the guide rail 24. The moving sleeve 11 also drives the push block 12 to move, ensuring that one side of the push block 12 is always in close contact with the top block 10. When the linkage spring 9 is compressed to its limit, the control sleeve 6 can no longer rotate, and at this time, the inner mating groove 14 of the moving sleeve 11 is no longer aligned with the mating block 15. The outer wall is limited, and then multiple cooperating springs 27 are simultaneously reset to push the cooperating block 15, so that the cooperating block 15 drives one side of the locking frame 16 to move outward. Then one end of the locking frame 16 will gradually slide out of the locking groove 17, and then the locking sleeve 5 will be pulled to one side to separate the locking sleeve 5 and the locking rod 3. Then, the other locking sleeves 5 and locking rods 3 are separated according to the above steps. Then the conical head 2 and the cylinder 1 can be separated, thereby realizing the separation of the water storage tank 22 and the soil storage tank 21.

[0029] When it is necessary to reassemble the water storage tank 22 and the soil storage tank 21, first, connect the water storage tank 22 and the soil storage tank 21 together, so that the multiple locking rods 3 set on one side of the water storage tank 22 pass through the soil storage tank 21 and the connecting cover 4, and connect the outer spiral plate 18 of the cylindrical head and the outer spiral plate 18 of the cylinder 1 together, so that the spiral plates 18 are continuous. Then, the locking sleeve 5 is fitted from the side of the connecting cover 4 to the outside of the locking rod 3. Then, the control sleeve 6 is released, the linkage spring 9 resets and pushes the linkage block 7 to rotate in the opposite direction to reset, and the linkage block 7 will drive the linkage rod 25 on one side to rotate in the opposite direction to reset along the linkage hole 26. At the same time, the linkage block 7 will drive the control sleeve 6 on one side to rotate in the opposite direction to reset, so that the control sleeve 6 drives the outer top block 10 to rotate in the opposite direction to reset. Then the top block 10 pushes the push block 12 to one side, so that the push block 12 slides to reset, and then pushes... Block 12 drives the movable sleeve 11 to slide and reset along the guide rail 24, and the movable sleeve 11 drives the inner mating groove 14 to slide and reset. Due to the chamfer design of one side of the inner wall of the mating groove 14 and one side of the outer wall of the mating block 15, the inner wall of the mating groove 14 gradually presses the mating block 15 inward, so that the mating block 15 moves and resets inward. The mating block 15 will squeeze the mating spring 27 on one side, so that the mating block 15 drives the locking bracket 16 on one side to gradually lock into the locking groove 17. At the same time, the movable sleeve 11 will squeeze the push spring 13. When the linkage spring 9 is fully reset, the control sleeve 6 is fully reset, and one end of the locking bracket 16 is reinserted into the locking groove 17 to form a locking relationship. Then, the other locking sleeves 5 are locked in accordance with the above steps, so as to achieve convenient connection and realize convenient assembly and fixing of the water storage tank 22 and the soil storage tank 21.

For all the fixed connections mentioned above, welding is preferred.
