Technical Field
[0001] This invention relates to the field of tailings dam sampling technology, specifically a safe tailings dam sampling and analysis device. Background Technology
[0002] Tailings dams are constructed by damming valleys or enclosing land, and are specifically used to store tailings (or other industrial waste) discharged after mineral processing in metal and non-metal mines. They are key supporting facilities for mineral processing and production, but also a source of high-potential artificial debris flow hazards.
[0003] In the prior art, patent CN220490433U discloses a tailings dam sampling device, including a base plate; a fixed frame is fixedly connected to the top center of the base plate, a cylinder is fixedly connected to the top of the fixed frame, a telescopic rod is installed at the bottom of the cylinder, a fixed plate is fixedly connected to the bottom of the telescopic rod, and a wheel-retracting mechanism is fixedly connected to the bottom of the fixed plate, enabling the wheels to fully enter the storage box, the base plate to fit against the ground surface, and the soil-entry head to enter the ground surface, thus fixing the position of the device and preventing the device from moving during subsequent sampling, which would affect the accuracy of sampling. Furthermore, it eliminates the need for manual positioning of the device, reducing the burden on personnel and improving sampling efficiency. The installation plate, buffer spring, and damping rod buffer the bumps generated during the movement of the device, providing good protection for the equipment on the device and extending its service life.
[0004] However, existing sampling equipment takes samples by pressing down the sampling tube. During the pressing process, the sampling tube is prone to bending due to the different densities at different locations in the tailings dam, resulting in inaccurate samples. Summary of the Invention
[0005] The purpose of this invention is to provide a safe tailings dam sampling and analysis device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a safe tailings dam sampling and analysis device, comprising: A fixed frame has a support fixed to its surface. A hydraulic cylinder is installed on the surface of the support. A piston rod is installed at the bottom of the support. A screw joint is installed at the bottom of the piston rod. A sampling tube is installed at the bottom of the screw joint. A slot is opened on the surface of the sampling tube. A pressure sensor is installed in the slot. A lifting ring is installed at the bottom of the sampling tube. A swing rod is installed on the surface of the lifting ring.
[0007] Preferably, the hydraulic cylinder can drive the piston rod to move up and down, and a limit ring is fixed on the surface of the piston rod. The limit ring and the screw joint move up and down with the piston rod.
[0008] Preferably, the sampling tube has multiple sets of slots on its surface, and a pressure sensor is fixed inside the slots. The sampling tube has insertion holes on its surface, and an insertion rod is inserted into the insertion holes. A spring is provided in the insertion holes, and the spring is connected to the end of the insertion rod.
[0009] Preferably, the other end of the plug rod is connected to a ring, which moves up and down with the plug rod. A connecting rod is fixed to the bottom of the ring, and a baffle is fixed to the bottom of the connecting rod. The connecting rod and the baffle move up and down with the ring.
[0010] Preferably, the top of the sampling tube is screwed onto the surface of the screw connector, and a lifting groove is provided on the bottom surface of the sampling tube. A lifting ring is fitted on the surface of the lifting groove, and the lifting ring can move up and down on the surface of the lifting groove. A limit strip is provided on the surface of the lifting groove, and the limit strip is inserted into the inside of the lifting ring, so that the lifting ring can move up and down along the limit strip.
[0011] Preferably, the top of the lifting ring is provided with a limit strip, the surface of the lifting ring is provided with a swing groove, a swing rod is inserted into the swing groove, and the end of the swing rod is provided with a rotating shaft, which is inserted into the inside of the swing groove.
[0012] Preferably, the swing arm is capable of swinging along the axis of rotation, and a protrusion is fixed at the end of the swing arm, which swings along with the swing arm.
[0013] Preferably, the swing rod has a protruding side exposed outside the swing groove, and the depth of the swing groove gradually increases from the top to the bottom.
[0014] Preferably, when the lifting ring rises on the surface of the lifting groove, the limiting strip is limited inside the lifting ring, so that the lifting ring gradually rotates during the rising and falling process.
[0015] Preferably, a limiting strip is provided at the top of the lifting groove, and after the lifting ring rises, the limiting strip on the surface of the lifting ring is locked between the limiting strips at the top of the lifting groove.
[0016] Compared with the prior art, the beneficial effects of the present invention are: The baffle proposed in this invention no longer obstructs the pressure sensor after it descends, allowing the pressure sensor to contact the surface of the screw joint. When the connection bends, the pressure sensor can detect the pressure change and drive the sampling tube to descend for sampling via a hydraulic cylinder. Upon detecting the bend, the sampling tube rises. During the descent, the swing rod is compressed and positioned in the swing groove, with the lifting ring at the bottom of the groove. As the sampling tube rises, the end of the swing rod is exposed outside the swing groove, causing it to swing and extend around its end axis. The obstruction of the swing rod causes the lifting ring to descend on the surface of the lifting groove. A limit strip is provided on the surface of the lifting groove, causing the lifting ring to rotate slightly. The swing rod agitates the tailings sand, reducing the impact of the tailings sand on the sampling tube angle when it descends again. Attached Figure Description

Detailed Implementation
[0024] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] Please see Figures 1 to 6The present invention provides a technical solution: Example 1: A safe tailings dam sampling and analysis device includes: a fixed frame 1, a support 2 fixed on the surface of the fixed frame 1, a hydraulic cylinder 3 on the surface of the support 2, a piston rod 4 at the bottom of the support 2, a threaded joint 6 at the bottom of the piston rod 4, a sampling tube 7 at the bottom of the threaded joint 6, a slot 14 on the surface of the sampling tube 7, a pressure sensor in the slot 14, a lifting ring 17 at the bottom of the sampling tube 7, and a swing rod 21 on the surface of the lifting ring 17. During the descent of the sampling tube 7, the swing rod 21 is compressed and located in the swing groove 18, and the lifting ring 17 is located at the bottom of the lifting groove 15. When the sampling tube 7 rises, the end of the swing rod 21 is exposed outside the swing groove 18, causing the swing rod 21 to swing and extend around the pivot of the end, and the lifting ring 17 descends on the surface of the lifting groove 15 due to the obstruction of the swing rod 21.
[0026] Example 2: Based on Example 1, the hydraulic cylinder 3 can drive the piston rod 4 to move up and down. A limit ring 5 is fixed on the surface of the piston rod 4. The limit ring 5 and the screw joint 6 move up and down with the piston rod 4. The sampling tube 7 has multiple slots 14 on its surface, and a pressure sensor is fixed inside each slot 14. A connector hole 8 is provided on the surface of the sampling tube 7, into which a connector rod 9 is inserted. A spring is installed in the connector hole 8, connecting the end of the connector rod 9. The top of the sampling tube 7 is screwed onto the surface of a screw connector 6. A lifting groove 15 is provided on the bottom surface of the sampling tube 7, and a lifting ring 17 is fitted onto the surface of the lifting groove 15. The lifting ring 17 can move up and down on the surface of the lifting groove 15. A limit strip 16 is provided on the surface of the lifting groove 15, and the limit strip 16 is inserted into the inside of the lifting ring 17, allowing the lifting ring 17 to move up and down along the limit strip 16. A limit strip 19 is provided on the top of the lifting ring 17. A swing groove 18 is provided on the surface of the lifting ring 17, into which a swing rod 21 is inserted. A rotating shaft is provided at the end of the swing rod 21, and the rotating shaft is inserted into the swing groove. Inside the swing groove 18, the swing rod 21 can swing along the rotating shaft. The end of the swing rod 21 is fixed with a protrusion 20. The protrusion 20 swings with the swing rod 21. The side of the swing rod 21 with the protrusion 20 is exposed outside the swing groove 18. The depth of the swing groove 18 gradually increases from the top to the bottom. When the lifting ring 17 rises on the surface of the lifting groove 15, the limiting strip 16 limits it inside the lifting ring 17, so that the lifting ring 17 gradually rotates during the rising and falling process. The top of the lifting groove 15 is provided with a limiting strip 19. After the lifting ring 17 rises, the limiting strip 19 on the surface of the lifting ring 17 is stuck between the limiting strips 19 on the top of the lifting groove 15. The surface of the lifting groove 15 is provided with a limiting strip 16. The limiting strip 16 makes the lifting ring 17 rotate slightly. The swing rod 21 stirs the tailings sand, so that when the sampling tube 7 falls again, the influence of the tailings sand on the angle of the sampling tube 7 is reduced.
[0027] The other end of the plug rod 9 is connected to the ring 11. The ring 11 moves up and down with the plug rod 9. A connecting rod 10 is fixed to the bottom of the ring 11, and a baffle plate 12 is fixed to the bottom of the connecting rod 10. The connecting rod 10 and the baffle plate 12 move up and down with the ring 11. The connecting rod 10 drives the baffle plate 12 to descend. A pressure sensor is installed in the slot 14. When the baffle plate 12 is located on one side of the slot 14, it can protect the pressure sensor. After the baffle plate 12 descends, it no longer blocks the pressure sensor.
[0028] The top of the sampling tube 7 is screwed onto the surface of the screw connector 6, and the limiting ring 5 is held against the surface of the ring 11, so that the insertion rod 9 is inserted into the interior of the insertion hole 8. The spring in the insertion hole 8 is compressed, and the connecting rod 10 drives the baffle plate 12 to descend. A pressure sensor is installed in the slot 14. When the baffle plate 12 is located on one side of the slot 14, it can protect the pressure sensor. After the baffle plate 12 descends, it no longer blocks the pressure sensor, and the pressure sensor can contact the surface of the screw connector 6. When the connection is bent, the pressure sensor can detect the pressure change. The sampling tube 7 is driven to descend by the hydraulic cylinder 3 to take a sample. After the bend is detected, the pressure sensor can detect the pressure change. As the sampling tube 7 rises, the swing rod 21 is compressed and positioned in the swing groove 18 during the descent, and the lifting ring 17 is located at the bottom of the lifting groove 15. When the sampling tube 7 rises, the end of the swing rod 21 is exposed outside the swing groove 18, causing the swing rod 21 to swing and extend around the pivot of the end. As the swing rod 21 is obstructed, the lifting ring 17 descends on the surface of the lifting groove 15. The surface of the lifting groove 15 is provided with a limiting strip 16, which causes the lifting ring 17 to rotate slightly. The swing rod 21 agitates the tailings sand, reducing the influence of the tailings sand on the angle of the sampling tube 7 when it descends again.
