Description

Technical Field

[0001] This invention relates to the field of mine backfill drainage sampling technology, specifically to an in-situ stratified sampling device and detection system for mine backfill drainage. Background Technology

[0002] Goaf areas left after ore mining need to be backfilled promptly. Tailings and other aggregates, cementitious materials, and water are thoroughly mixed to form a backfill slurry, which is then transported through pipelines into the goaf. After a certain curing period, it forms a backfill body with sufficient strength to control surrounding rock deformation. Once the backfill slurry is delivered to the goaf, free water in the slurry separates through the backfill body itself and drainage structures (such as wall panels and filter cloths). This is a crucial step in the backfilling process, aiming to accelerate the consolidation of the backfill body and improve its early strength. The strength of the backfill body is closely related to the hydration of the cementitious materials and their hydration products. Inside the backfill material, the cementitious materials continuously undergo the process of dissolving raw materials to generate new ions and ions recombine to form hydration products. Therefore, in the initial stage after the backfill slurry enters the goaf, the water medium within the slurry contains a large number of chemical ions that need to combine into hydration products. These chemical ions are inevitably lost with the discharge of drainage water, thus affecting the strength of the backfill body. Therefore, it is necessary to collect and sample the filtration water of the filling material and conduct dynamic monitoring to provide a scientific basis for predicting the strength of the filling material and evaluating the quality of the panel wall.

[0003] Currently, the common method for collecting moisture from mine backfill materials is to lay filter cloth on the backfill wall and fix multiple sampling units on it. Moisture is guided into these sampling units through the natural flow of moisture within the backfill material. However, this method has several significant drawbacks. First, the automatic flow of moisture is slow, resulting in low collection efficiency and failing to meet the needs for rapid acquisition and real-time monitoring, thus affecting the responsiveness to dynamic changes in the moisture content of the backfill material. Second, the fixed installation of multiple sampling units complicates the sampling process, often requiring significant time for disassembly and reinstallation when replacement or maintenance is needed.

[0014] A system for in-situ stratified sampling and detection of mine filling material filter water, based on the aforementioned in-situ stratified sampling and detection device for mine filling material filter water, includes the following steps: S1. In use, the filter cloth is laid on the filling plate wall, and then the support vertical rod on the base frame is attached to the filter cloth. At the same time, the drive motor drives the drive screw to rotate. The lifting plate on the drive screw will be limited by the limit slide rod and the limit slide groove, thereby driving the connecting vertical block on the lifting plate to adjust its height. After the position is adjusted, the electric push rod drives the collection slider to adjust its horizontal position. The conical tube on the collection slider is attached to the filter cloth. At the same time, the vacuum pump is started, and the water in the filling plate wall is sucked into the connecting pipe by the effect of negative pressure. Then, the water is allowed to enter the three-way connector by gravity. At the same time, one of the valves is opened to allow water to enter the collection bottle. Then, the drive motor drives the lifting plate to adjust its second position. As described above, the original valve is closed and the other valve is opened to allow the collection bottle to collect water from other positions. By using different collection bottles, water can be collected in layers, improving the collection effect. S2. When the sampling slider moves inward, it drives the push rod through the auxiliary push frame. The push rod and the positioning frame work together, the positioning frame connects to the locking slider, and the locking slider slides to the locking groove limit the movement. This causes the two side slides to move to the sides. The two side slides then work together with the auxiliary rod and the side frame, as well as with the positioning frame, to make the two side slides press tightly against the filter cloth surface and spread out to the sides. The sliding of the side slides against the filter cloth ensures that the filter cloth in the area to be sampled is in a taut state, improving the sealing between the conical tube and the filter cloth and ensuring the effect of layered sampling. S3. When the side slide plate slides to both sides, the auxiliary rotating rod on the side slide plate will drive the auxiliary gear to move synchronously. Then, the auxiliary gear will mesh with the tooth block group on the auxiliary crossbar. When the auxiliary gear rotates, it will mesh with the tooth block group on the auxiliary rotating rod, thus being in a rotating state. By using the reverse rotation of the bonding roller, the bonding roller will slide and tighten the filter cloth in the collection area to the outside, further improving the sealing between the conical bonding tube and the filter cloth. S4. When the lifting plate is adjusted in height, it will drive the support frame to move synchronously. The support push rod on the support frame will drive the connecting crossbar to move. The connecting crossbar will slide horizontally through the limiting sliding between the lower frame and the horizontal slide groove. When the lower frame slides horizontally, the lower frame will adjust the angle of the connecting push rod through the cooperation between the connecting push rod and the upper frame and the limiting of the upper frame and the support vertical groove. Through the triangular support principle, the stability of the acquisition component is ensured during the layered acquisition process. S5. After collecting samples from the filling filter through the steps S1-S5 above, remove the collection bottles from the mounting plate and then test them.

[0015] This invention provides an in-situ stratified sampling device and detection system for filter water from mine filling materials. Compared with existing technologies, it has the following advantages: 1. This invention involves laying filter cloth on a filling plate wall, then attaching the supporting vertical rods on the base frame to the filter cloth. Simultaneously, a drive motor rotates the drive screw, causing a lifting plate on the drive screw to adjust its height via a limiting slide rod and a limiting slide groove. After the position is adjusted, an electric push rod drives the collection slider to adjust its horizontal position. The conical tube on the collection slider attaches to the filter cloth. A vacuum pump is activated, using negative pressure to draw water from the filling plate wall into the connecting pipe. Gravity then facilitates the water entering the three-way connector. One valve is opened to allow water to enter the collection bottle. The drive motor then adjusts the lifting plate to a second position, closing the original valve and opening the other, allowing the collection bottle to collect water from other locations. This layered water collection using different collection bottles improves the collection efficiency. 2. In this invention, when the sampling slider moves inward, it drives the push rod to move through the auxiliary push frame. By utilizing the cooperation between the push rod and the positioning frame, the connection between the positioning frame and the locking slider, and the limiting sliding between the locking slider and the locking groove, the two side slides are driven to move to both sides. The two side slides then utilize the cooperation between the auxiliary rod and the side frame, as well as the cooperation between the auxiliary rod and the positioning frame, to make the two side slides tightly adhere to the filter cloth surface and unfold to both sides. By utilizing the sliding of the side slides against the filter cloth, it is ensured that the filter cloth in the area to be sampled is in a taut state, improving the sealing between the conical tube and the filter cloth, and ensuring the effect of layered sampling. 3. In this invention, when the side slide plate slides to both sides, the auxiliary rotating rod on the side slide plate will drive the auxiliary gear to move synchronously. Then, the auxiliary gear meshes with the tooth block group on the auxiliary crossbar. When the auxiliary gear rotates, it will mesh with the tooth block group on the auxiliary rotating rod, thus being in a rotating state. By utilizing the reverse rotation of the bonding roller, the bonding roller will slide and tighten the filter cloth in the collection area to the outside, further improving the sealing between the conical bonding tube and the filter cloth.

[0016] 4. In this invention, when the lifting plate is adjusted in height, it will synchronously drive the support frame to move. The support push rod on the support frame will drive the connecting crossbar to move. The connecting crossbar will slide horizontally through the limiting sliding between the lower frame and the horizontal slide groove. When the lower frame slides horizontally, the lower frame will adjust the angle of the connecting push rod through the cooperation between the connecting push rod and the upper frame and the limiting of the upper frame and the support vertical groove. Through the triangular support principle, the stability of the acquisition component during the layered acquisition process is ensured. Attached Figure Description

[0020] Please see Figures 1-8This invention relates to an in-situ stratified sampling device for filter water in mine filling materials, comprising a filter cloth 1 laid on a filling plate wall and a device base plate 2.

A collection component is provided on the lifting plate 8, and a collection bottle 9 is provided on the collection component. The collection component includes a connecting vertical block 12 fixedly mounted on the lifting plate 8. An electric push rod 13 is fixedly mounted on the connecting vertical block 12. A collection slider 14 is fixedly mounted on the output shaft of the electric push rod 13. An L-shaped fixed rod 15 is fixedly mounted on the lower end face of the lifting plate 8.

The sliding rod 17 and the inner side of the U-shaped support rod 5 are provided with a limiting sliding groove 18. A vacuum pump 19 is fixedly installed on the collection block 16. The input end of the vacuum pump 19 is fixedly connected to a connecting pipe 20. The end of the connecting pipe 20 away from the vacuum pump 19 is fixedly connected to a tapered tube 21. A three-way connector 22 is fixedly connected to the connecting pipe 20. Valves 46 are provided at the three outlets of the three-way connector 22. Three mounting plates 23 are fixedly installed on the side end face of the collection block 16. The limiting sliding rod 17 is away from the connecting vertical block 12. One end extends into the interior of the limiting slide groove 18 and is slidably installed with the limiting slide groove 18. The collecting slider 14 is slidably installed with the L-shaped fixed rod 15. The three collecting bottles 9 and the three mounting plates 23 are detachably installed. The interfaces of the three-way connector 22 are respectively connected to the three collecting bottles 9. The positions of the three collecting bottles 9 are all below the connecting pipe 20. Using gravity, the water in the connecting pipe 20 can be opened through the valve 46 on the three-way connector 22 to facilitate entering the different collecting bottles 9.

[0021] In this embodiment, the filter cloth 1 is laid on the filling plate wall, and then the supporting vertical rod 4 on the base frame rod 3 is attached to the filter cloth 1. At the same time, the drive motor 6 drives the drive screw 7 to rotate. The lifting plate 8 on the drive screw 7 will be limited by the limiting slide rod 17 and the limiting slide groove 18, thereby driving the connecting vertical block 12 on the lifting plate 8 to adjust its height. After the position is adjusted, the electric push rod 13 drives the collection slider 14 to adjust its horizontal position. The conical tube 21 on the collection slider 14 is attached to the filter cloth 1, and the real machine is started. The empty pump 19 uses negative pressure to draw water from the filling wall into the connecting pipe 20, and then uses gravity to facilitate the water entering the three-way connector 22. At the same time, one of the valves 46 is opened to allow water to enter the collection bottle 9. The drive motor 6 then drives the lifting plate 8 to adjust to a second position. As described above, the original valve 46 is closed and the other valve 46 is opened, allowing the collection bottle 9 to collect water from other locations. By using different collection bottles 9, water can be collected in layers, improving the collection effect.

[0022] The support assembly includes a support frame 24 fixedly mounted on the lifting plate 8, a support push rod 25 rotatably mounted on the support frame 24, a support vertical groove 26 formed on the support vertical rod 4, an upper frame 27 slidably mounted on the support vertical groove 26, a connecting push rod 28 rotatably mounted on the upper frame 27, a horizontal sliding groove 29 formed on the upper end face of the base frame rod 3, a lower frame 30 slidably mounted on the horizontal sliding groove 29, a connecting crossbar 31 fixedly mounted on the lower frame 30, symmetrically arranged limiting rings 32 fixedly mounted on the connecting crossbar 31, and the end of the connecting push rod 28 away from the upper frame 27 connected to the lower frame 30. The frame 30 is rotatably connected, and the end of the support push rod 25 away from the support frame 24 is rotatably installed with the connecting crossbar 31. The position of the support push rod 25 on the connecting crossbar 31 is between two limiting rings 32. Both the support push rod 25 and the connecting push rod 28 are arranged at an angle. The limiting rings 32 can ensure that the support push rod 25 can only rotate on the connecting crossbar 31 and will not move in position on the connecting crossbar 31. Moreover, the lower frame 30 can only move horizontally in the horizontal slide groove 29, and there will be no separation during the horizontal sliding process.

[0023] In this embodiment, when the lifting plate 8 is adjusted in height, it will synchronously drive the support frame 24 to move. The support push rod 25 on the support frame 24 will drive the connecting crossbar 31 to move. The connecting crossbar 31 will slide horizontally through the limiting sliding between the lower frame 30 and the horizontal slide groove 29. When the lower frame 30 slides horizontally, the lower frame 30 will adjust the angle of the connecting push rod 28 through the cooperation of the connecting push rod 28 and the upper frame 27 and the limiting of the upper frame 27 and the support vertical groove 26. Through the triangular support principle, the stability of the acquisition component during the layered acquisition process is ensured.

[0024] An auxiliary component is provided on the front side of the filter cloth 1. The auxiliary component includes a side slide plate 10 and a bonding roller 11. The auxiliary component includes a side connecting frame 33 fixedly mounted on the base rod 3. An auxiliary connecting rod 34 is rotatably connected to the side connecting frame 33. A positioning connecting frame 35 is fixedly mounted on the side end face of the side slide plate 10. A sliding groove 36 is opened on the side end face of the side slide plate 10. A sliding block 37 is slidably mounted in the sliding groove 36. An installation connecting frame 38 is fixedly mounted on the side end face of the sliding block 37. An auxiliary push frame 39 is fixedly mounted on the side end face of the collection slider 14. A pushing connecting rod 40 is rotatably connected to the auxiliary push frame 39. An auxiliary horizontal rod 41 is fixedly mounted on the front surface of the support vertical rod 4. A toothed block assembly 42 is fixedly mounted on the inner side of the auxiliary horizontal rod 41. A side sliding groove 43 is opened on the inner side of the side slide plate 10. An auxiliary rotating rod 44 is rotatably mounted inside the side sliding groove 43. An auxiliary rotating rod 44 is fixedly mounted on the auxiliary rotating rod 44. An auxiliary gear 45 is provided. The end of the auxiliary connecting rod 34 away from the side connecting frame 33 is rotatably connected to the positioning connecting frame 35. The end of the pushing connecting rod 40 away from the auxiliary push frame 39 is rotatably connected to the mounting connecting frame 38. Both the auxiliary connecting rod 34 and the pushing connecting rod 40 are arranged at an angle. The auxiliary crossbar 41 is located inside the side slide plate 10. The auxiliary gear 45 meshes with the tooth block assembly 42. The bonding roller 11 is fixedly installed on the auxiliary connecting rod 34 and is located inside the auxiliary gear 45. Since the auxiliary gear 45 meshes with the tooth block assembly 42, the direction of rotation of the auxiliary gear 45 is opposite to the direction of movement when it moves with the side slide plate 10. The reverse rotation of the auxiliary gear 45 drives the bonding roller 11 to rotate. The rotation of the bonding roller 11 increases the friction between the bonding roller 11 and the filter cloth 1, effectively improving the flatness and adhesion of the filter cloth 1 on the filling plate wall.

[0025] In this embodiment, when the sampling slider 14 moves inward, it drives the push rod 40 to move via the auxiliary push frame 39. The cooperation between the push rod 40 and the positioning frame 35, the connection between the positioning frame 35 and the locking slider 37, and the limiting sliding of the locking slider 37 and the locking groove 36 cause the two side slide plates 10 to move to both sides. The two side slide plates 10 then utilize the cooperation between the auxiliary link 34 and the side frame 33, and the cooperation between the auxiliary link 34 and the positioning frame 35, to cause the two side slide plates 10 to unfold tightly against the surface of the filter cloth 1. The sliding contact of the side slide plates 10 with the filter cloth 1 ensures that the sample is collected... The filter cloth 1 in the collection area is in a taut state, which improves the sealing between the conical tube 21 and the filter cloth 1 and ensures the effect of layered collection. When the side slide plate 10 slides to both sides, the auxiliary rotating rod 44 on the side slide plate 10 will drive the auxiliary gear 45 to move synchronously. Then, the auxiliary gear 45 meshes with the tooth block group 42 on the auxiliary crossbar 41. When the auxiliary gear 45 rotates, it will mesh with the tooth block group 42 on the auxiliary rotating rod 44, thus being in a rotating state. By using the reverse rotation of the bonding roller 11, the bonding roller 11 slides and pulls the filter cloth 1 in the collection area outward to tighten it, further improving the sealing between the conical tube 21 and the filter cloth 1.

[0026] A system for in-situ stratified sampling and detection of mine filling material filter water, based on the aforementioned in-situ stratified sampling and detection device for mine filling material filter water, includes the following steps: S1. In use, the filter cloth 1 is laid on the filling plate wall, and then the supporting vertical rod 4 on the base frame rod 3 is attached to the filter cloth 1. At the same time, the drive motor 6 drives the drive screw 7 to rotate. The lifting plate 8 on the drive screw 7 will be limited by the limiting slide rod 17 and the limiting slide groove 18, thereby driving the connecting vertical block 12 on the lifting plate 8 to adjust its height. After the position is adjusted, the electric push rod 13 drives the collection slider 14 to adjust its horizontal position. The conical tube 21 on the collection slider 14 is attached to the filter cloth 1. At the same time, the real machine is started. The air pump 19 uses negative pressure to draw water from the filling wall into the connecting pipe 20, and then uses gravity to facilitate the water entering the three-way connector 22. At the same time, one of the valves 46 is opened to allow water to enter the collection bottle 9. The drive motor 6 then drives the lifting plate 8 to adjust to a second position. As described above, the original valve 46 is closed and the other valve 46 is opened, which allows the collection bottle 9 to collect water from other positions. By using different collection bottles 9, water can be collected in layers, improving the collection effect. S2. When the sampling slider 14 moves inward, the sampling slider 14 will drive the push rod 40 to move through the auxiliary push frame 39. By utilizing the cooperation between the push rod 40 and the positioning frame 35, the connection between the positioning frame 35 and the locking slider 37, and the limiting sliding between the locking slider 37 and the locking groove 36, the two side slide plates 10 will move to both sides. The two side slide plates 10 will then utilize the cooperation between the auxiliary link 34 and the side frame 33, and the cooperation between the auxiliary link 34 and the positioning frame 35, so that the two side slide plates 10 will be tightly attached to the surface of the filter cloth 1 and spread out to both sides. By using the sliding of the side slide plates 10 against the filter cloth 1, the filter cloth 1 in the area to be sampled is kept in a taut state, improving the sealing between the conical tube 21 and the filter cloth 1, and ensuring the effect of layered sampling. S3. When the side slide plate 10 slides to both sides, the auxiliary rotating rod 44 on the side slide plate 10 will drive the auxiliary gear 45 to move synchronously. Then, the auxiliary gear 45 meshes with the tooth block group 42 on the auxiliary crossbar 41. When the auxiliary gear 45 rotates, it will mesh with the tooth block group 42 on the auxiliary rotating rod 44, thus being in a rotating state. By using the reverse rotation of the bonding roller 11, the bonding roller 11 will slide and tighten the filter cloth 1 in the collection area to the outside, further improving the sealing between the conical bonding tube 21 and the filter cloth 1. S4. When the lifting plate 8 is adjusted in height, it will drive the support frame 24 to move synchronously. The support push rod 25 on the support frame 24 will drive the connecting crossbar 31 to move. The connecting crossbar 31 will slide horizontally through the limiting sliding between the lower frame 30 and the horizontal slide groove 29. When the lower frame 30 slides horizontally, the lower frame 30 will adjust the angle of the connecting push rod 28 through the cooperation of the connecting push rod 28 and the upper frame 27 and the limiting of the upper frame 27 and the support vertical groove 26. Through the triangular support principle, the stability of the acquisition component during the layered acquisition process is ensured. S5. After collecting samples from the filling filter through the steps S1-S5 above, remove the collection bottles 9 from the mounting plate 23 and then test them.

[0027] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.

10. A system for in-situ stratified sampling and detection of mine filling material filter water, based on the in-situ stratified sampling and detection device for mine filling material filter water according to any one of claims 1-9, characterized in that, Includes the following steps: S1. In use, the filter cloth (1) is laid on the filling plate wall, and then the support vertical rod (4) on the base frame rod (3) is attached to the filter cloth (1). At the same time, the drive motor (6) drives the drive screw (7) to rotate. The lifting plate (8) on the drive screw (7) will be limited by the limit slide rod (17) and the limit slide groove (18), thereby driving the connecting vertical block (12) on the lifting plate (8) to adjust its height. After the position is adjusted, the electric push rod (13) drives the collection slider (14) to adjust its horizontal position. The conical tube (21) on the collection slider (14) is attached to the filter cloth (1). 1) At the same time, start the vacuum pump (19) to use the negative pressure effect to draw the water in the filling plate wall into the connecting pipe (20). Then, use gravity to facilitate the water to enter the three-way pipe (22). At the same time, open one of the valves (46) to facilitate the water to enter the collection bottle (9). Then, use the drive motor (6) to drive the lifting plate (8) to make a second position adjustment. By closing the original valve (46) and opening the other valve (46), it is convenient for the collection bottle (9) to collect water from other positions. Through different collection bottles (9), the water is collected in layers, which improves the collection effect. S2. When the sampling slider (14) moves inward, the sampling slider (14) will drive the push rod (40) to move through the auxiliary push frame (39). With the cooperation of the push rod (40) and the positioning frame (35), the connection between the positioning frame (35) and the locking slider (37), and the limiting sliding between the locking slider (37) and the locking groove (36), the two side slides (10) will move to both sides. The two side slides (10) will then use the cooperation of the auxiliary link (34) and the side frame (33), and the cooperation of the auxiliary link (34) and the positioning frame (35), so that the two side slides (10) will be tightly attached to the surface of the filter cloth (1) and spread out to both sides. By using the sliding of the side slides (10) against the filter cloth (1), the filter cloth (1) in the area to be sampled is kept in a taut state, improving the sealing between the conical tube (21) and the filter cloth (1), and ensuring the effect of layered sampling. S3. When the side slide plate (10) slides to both sides, the auxiliary rotating rod (44) on the side slide plate (10) will drive the auxiliary gear (45) to move synchronously. Then, the auxiliary gear (45) meshes with the tooth block group (42) on the auxiliary crossbar (41). When the auxiliary gear (45) rotates, it will mesh with the tooth block group (42) on the auxiliary rotating rod (44) and thus be in a rotating state. By using the reverse rotation of the bonding roller (11), the bonding roller (11) will slide and tighten the filter cloth (1) in the collection area to the outside, further improving the sealing between the conical bonding tube (21) and the filter cloth (1). S4. When the lifting plate (8) is adjusted in the high and low position, it will drive the support frame (24) to move synchronously. The support push rod (25) on the support frame (24) will drive the connecting crossbar (31) to move. The connecting crossbar (31) will slide horizontally through the limit of the lower frame (30) and the horizontal slide groove (29). When the lower frame (30) slides horizontally, the lower frame (30) will adjust the angle of the connecting push rod (28) through the cooperation of the connecting push rod (28) and the upper frame (27) and the limit of the upper frame (27) and the support vertical groove (26). Through the triangular support principle, the stability of the acquisition component during the layered acquisition process is ensured. S5. After collecting the filler filter through the above steps S1-S5, remove the collection bottles (9) from the mounting plate (23) and then test them.
