Description

Technical Field

[0001] This invention relates to the field of sample collection technology, specifically to a sample collection device for soil environments contaminated by waste aluminum ash. Background Technology

[0002] Waste aluminum ash is a waste residue generated during the aluminum industry production process. It is divided into primary aluminum ash and secondary aluminum ash. Its environmental hazards are mainly due to its reactivity; some of it also has leaching toxicity or releases flammable gases when it comes into contact with water, posing a high environmental risk. Aluminum ash also causes pollution to the environment, such as dust and ammonia, and becomes alkaline when it comes into contact with water, which can disrupt the soil's pH balance.

[0003] Waste aluminum ash pollutes the soil environment during its storage and landfilling processes. In addition, it undergoes various chemical reactions with the soil, producing more harmful substances that exacerbate soil pollution. The harmful components also have a certain impact on the surrounding water bodies and atmospheric environment.

[0004] Collecting and testing soil samples contaminated with waste aluminum ash helps to evaluate the degree of soil pollution by measuring fluorides, cyanides, and other pollutants. This reflects the pollution status of waste aluminum ash on the surrounding soil environment and allows for the development of comprehensive measures and recommendations to reduce soil pollution from waste aluminum ash. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a sample collection device for soil environments contaminated by waste aluminum ash.

[0006] The technical solution of the present invention is: a sample collection device for soil contaminated by waste aluminum ash, comprising a platform, a drill cylinder for collecting soil contaminated by waste aluminum ash, and a drive rod for driving the drill cylinder to move up and down. The platform has a through hole in the middle, and a guide ring surrounding the through hole is provided above the platform. The guide ring is connected to a connecting seat provided on the platform.

[0007] The drill barrel is slidably connected to the through hole, and a drive plate is provided on the upper end face of the drill barrel. A double-sided toothed plate is provided on the drive plate along the vertical direction. A first toothed ring for driving the double-sided toothed plate downwards is provided above a platform on one side of the double-sided toothed plate, and a second toothed ring for driving the double-sided toothed plate upwards is provided above a platform on the other side of the double-sided toothed plate. Both the first and second toothed rings are rotatably connected to a support seat provided on the platform. A rotating rod is provided on the central axis of both the first and second toothed rings, and both ends of the rotating rod are rotatably connected to the cross-sectional end of a guide ring.

[0008] Both the first and second gear rings have ratchet rings on their inner surfaces. A first drive disc is mounted on the rotating rod corresponding to the first gear ring, and a second drive disc is mounted on the rotating rod corresponding to the second gear ring. A first lever is mounted on the first drive disc, and a second lever is mounted on the second drive disc. One end of the first lever is rotatably connected to the first drive disc, and one end of the second lever is rotatably connected to the second drive disc. Both the first and second drive discs have springs for engaging the first and second levers with the ratchet rings.

[0009] One end of the drive rod is provided with a collar for fitting onto the guide ring. The inner ring surface of the collar is provided with a locking block for engaging with the rotating rod. The locking block is slidably connected to a groove on the inner ring surface of the collar, and the locking block is provided with an airbag column connected to the bottom surface of the groove. The drive rod is rotatably connected to a slide seat on the platform through the collar. The other end of the drive rod is provided with a pressure plate for squeezing the cylindrical airbag to control the extension and retraction of the airbag column. The pressure plate is slidably connected to the groove. The cylindrical airbag is embedded in the groove of the drive rod, and the cylindrical airbag is connected to the airbag column through an air tube embedded in the drive rod.

[0010] Furthermore, the platform is hollow inside, and an arc-shaped hole is provided on the platform located on one side of the drive rod. A toothed rod is provided vertically inside the arc-shaped hole located at the position of the first toothed ring, and the upper end of the toothed rod is hinged to the middle of the drive rod.

[0011] The drill barrel has a hollow side wall, and a rotating ring is provided inside the cavity. The rotating ring is rotatably connected to the drill barrel, and the lower end of the rotating ring extends out of the drill barrel and is provided with several first cutting blades.

[0012] The inner bottom surface of the platform is provided with an arc-shaped rack that is slidably connected to it. A shaft is provided on one side of the arc-shaped rack in the vertical direction. The shaft is rotatably connected to the platform. A first bevel gear is provided at the upper end of the shaft. A first spur gear is provided at the lower end of the shaft for meshing with the arc-shaped rack. A second bevel gear is provided on one side of the first bevel gear for meshing with it. A second spur gear is provided on the end face of the second bevel gear for meshing with the rack. The second spur gear is provided with a rotating shaft that is rotatably connected to the inner wall of the platform. The arc-shaped rack passes through the platform and the drill cylinder in sequence through a connecting rod and is limited and slidably engaged with a connecting plate provided on the rotating ring. The platform and the drill cylinder are both provided with square holes for moving the connecting rod.

[0013] Explanation: By setting up components such as the toothed rod and the arc-shaped toothed rack, the rotating ring inside the drill barrel can be controlled to reciprocate while the drive rod drives the first toothed ring. The first blade of the rotating ring assists the drill barrel in drilling, which improves the efficiency of the sample collection device in collecting waste aluminum ash contaminated soil. Furthermore, the sample collection device of this invention improves the drilling efficiency without the need for an additional drive motor, thus enabling it to cope with various extremely complex collection environments such as those without power supply.

[0014] Furthermore, anti-collision pads are provided on the other end of the drive rod and on the platform located at the positions of the first toothed ring and the second toothed ring.

[0015] Note: The anti-collision pads are made of rubber or other commercially available materials with cushioning and energy absorption properties. By setting the anti-collision pads, the possibility of collision between the drive rod and the platform can be effectively reduced, avoiding collision damage to the drive rod and platform due to long-term use, thereby effectively extending the service life of the sample collection device of this invention.

[0016] Furthermore, the card block is provided with several springs connected to the bottom surface of the sink, and the rotating rod is provided with a slot for engaging with the card block. The bottom surface of the slot and the end face of the card block are respectively provided with magnetic sheets for magnetic attraction.

[0017] Note: The spring design ensures that the locking block can retract stably into the slot when not triggered, preventing obstruction of the smooth sliding of the drive rod on the collar; the magnetic plate design further ensures stable engagement between the locking block and the slot.

[0018] Furthermore, the lower inner wall of the drill barrel is provided with multiple grooves, and each groove is provided with a fan-shaped airbag for unfolding and sealing the bottom of the drill barrel. The fan-shaped airbag is provided with a folding bracket.

[0019] An arc-shaped airbag is provided on the inner top surface of the platform between the second toothed ring and the toothed bar. The arc-shaped airbag is connected to each of the fan-shaped airbags through an air tube.

[0020] The folding support includes a main rod and a support rod. One end of the support rod is hinged to the middle of the main rod, and the other end of the support rod abuts against the inner wall of the fan-shaped airbag. One end of the main rod is rotatably connected to the fan-shaped airbag located at one end of the groove. The other end of the main rod is attached to the inner wall of the outer side of the fan-shaped airbag, and a second blade for cutting soil contaminated by waste aluminum ash is provided on the outer wall of the outer side of the fan-shaped airbag. The main rod is an arc-shaped rod with the same curvature as the inner wall of the drill barrel.

[0021] Explanation: By setting up components such as the fan-shaped airbag and the folding bracket, the bottom of the drill barrel can be sealed after the drive rod switches from the first toothed ring to the second toothed ring, thereby preventing the sample from slipping out of the drill barrel when extracting soil samples contaminated by waste aluminum ash, which would affect the collection efficiency. Furthermore, the sample collection device of this invention improves the stability of the collected samples without the need for additional drive motors, thus enabling it to cope with various extremely complex collection environments such as those without power supply.

[0022] Furthermore, the rack includes a straight rack and a rod body, the straight rack being slidably connected to a vertical groove provided on the rod body, and a plurality of springs being provided between the straight rack and the rod body.

[0023] Explanation: The rack structure improves the stability of the meshing between the rack and the second spur gear, preventing slippage caused by insufficient contact. This slippage also helps maintain the rack's transmission efficiency and extend the lifespan of components such as the rack and the second spur gear.

[0024] Furthermore, the bottom of the slide is provided with a magnetic sheet, and the platform located at the positions of the first toothed ring and the second toothed ring is provided with a magnetic sheet for engaging and positioning with the slide.

[0025] Note: The magnetic plate provides positioning guidance for the drive rod at the first and second gear ring positions, preventing slippage and ensuring the stability of the drive rod during use.

[0026] Furthermore, the platform sidewall on the side opposite to the drive rod is provided with an extension plate for contacting the ground.

[0027] Note: The extension plate can be pressed when operating the drive rod, which improves the stability of the sample collection device during use.

[0028] The beneficial effects of this invention are:

[0029] (1) The sample collection device of the present invention can be quickly switched between two driving modes: drilling down and lifting up. The drilling depth is controllable, saving time and effort, and is easy to operate, thus optimizing the user experience of operators collecting soil samples in waste aluminum ash contaminated soil environments.

[0030] (2) The sample collection device of the present invention is driven by a combination of components such as a first toothed ring, a second toothed ring and a drive rod. It can utilize the characteristics of ratchet transmission to realize two types of driving of drilling and lifting of the drill barrel by docking with the first toothed ring or the second toothed ring respectively during the reciprocating swing of the drive rod. The device has a high degree of integration, multiple functions, and the operation process of drilling and lifting is simple and easy to understand.

[0031] (3) The sample collection device of the present invention, by setting components such as toothed rods, can control the rotating ring inside the drill barrel to reciprocate while the drive rod drives the first toothed ring, thereby using the first blade of the rotating ring to assist the drill barrel to drill down, thereby improving the efficiency of the sample collection device in collecting waste aluminum ash contaminated soil.

Detailed Implementation

[0044] The present invention will now be described in more detail with reference to specific embodiments, so as to better demonstrate the advantages of the present invention.

[0045] Example 1

[0046] like Figure 1As shown, a sample collection device for soil contaminated by waste aluminum ash is characterized by comprising a platform 1, a drill cylinder 2 for collecting soil contaminated by waste aluminum ash, and a drive rod 3 for driving the drill cylinder 2 to move up and down. The platform 1 has a through hole 11 in the middle, and a guide ring 12 surrounding the through hole 11 is provided above the platform 1. The guide ring 12 is connected to a connecting seat 13 provided on the platform 1.

[0047] like Figure 1 As shown, the drill barrel 2 is slidably connected to the through hole 11, and a drive plate 4 is provided on the upper end face of the drill barrel 2. A double-sided toothed plate 41 is provided on the drive plate 4 along the vertical direction. A first toothed ring 5 for driving the double-sided toothed plate 41 to move downward is provided above the platform 1 on one side of the double-sided toothed plate 41, and a second toothed ring 6 for driving the double-sided toothed plate 41 to move upward is provided above the platform 1 on the other side of the double-sided toothed plate 41. The first toothed ring 5 and the second toothed ring 6 are both rotatably connected to the support seat provided on the platform 1. A rotating rod 15 is provided on the central axis of the first toothed ring 5 and the second toothed ring 6. The two ends of the rotating rod 15 are respectively rotatably connected to the cross-sectional port of the guide ring 12.

[0048] like Figure 3 As shown, both the first toothed ring 5 and the second toothed ring 6 have ratchet rings on their inner ring surfaces. A first drive disc 51 is mounted on the rotating rod 15 corresponding to the first toothed ring 5, and a second drive disc 61 is mounted on the rotating rod 15 corresponding to the second toothed ring 6. A first lever 52 is mounted on the first drive disc 51, and a second lever 62 is mounted on the second drive disc 61. One end of the first lever 52 is rotatably connected to the first drive disc 51, and one end of the second lever 62 is rotatably connected to the second drive disc 61. Both the first drive disc 51 and the second drive disc 61 have springs for contacting the ratchet rings with the first lever 52 and the second lever 62.

[0049] like Figure 1 , 2As shown, one end of the drive rod 3 is provided with a collar 31 for fitting onto the guide ring 12. The inner ring surface of the collar 31 is provided with a locking block 32 for engaging with the rotating rod 15. The locking block 32 is slidably connected to a groove on the inner ring surface of the collar 31. The locking block 32 is provided with an airbag column 33 connected to the bottom surface of the groove. The locking block 32 is also provided with several springs connected to the bottom surface of the groove. The rotating rod 15 is provided with a slot for engaging with the locking block 32. The bottom surface of the slot and the end face of the locking block 32 are respectively provided with magnetic sheets for magnetic attraction. The drive rod 3 passes through... The drive rod 3 is rotatably connected to the slide 16 on the platform 1 via the collar 31. The slide 16 has a magnetic sheet at its bottom. The platform 1, located at the positions of the first toothed ring 5 and the second toothed ring 6, has magnetic sheets for engaging and positioning with the slide 16. The other end of the drive rod 3 has a pressure plate 35 for compressing the cylindrical airbag 34 to control the extension and retraction of the airbag column 33. The pressure plate 35 is slidably connected to the groove. The cylindrical airbag 34 is embedded in the groove of the drive rod 3, and the cylindrical airbag 34 is connected to the airbag column 33 through an air tube embedded in the drive rod 3.

[0050] like Figure 1 As shown, anti-collision pads are provided on the other end of the drive rod 3 and on the platform 1 located at the positions of the first toothed ring 5 and the second toothed ring 6. An extension plate 19 for contacting the ground is provided on the side wall of the platform 1 opposite to the drive rod 3.

[0051] The working method of the above-mentioned sample collection device is as follows:

[0052] Place the sample collection device on the surface of the soil to be collected in the waste aluminum ash contaminated soil environment, and then step on the extension plate 19 to prevent the sample collection device from shifting during the collection process.

[0053] Then, the drive rod 3 is moved to the position of the first toothed ring 5. When feedback is felt that the slide 16 and the magnetic plate of the platform 1 are attracted, it indicates that it has moved to the corresponding position. Press the pressure plate 35 by hand to squeeze the cylindrical airbag 34. Under the action of the cylindrical airbag 34, the airbag column 33 is inflated through the air tube. Then, the airbag column 33 pushes the locking block 32 to overcome the spring force and engage with the slot of the rotating rod 15. Then, press the drive rod 3 up and down to make the drive rod 3 swing around the center of the collar 31 and drive the rotating rod 15 to rotate. The rotating rod 15 drives the first drive disk 51 to rotate. With the cooperation of the first lever 52, the spring and the ratchet ring, the first toothed ring 5 rotates. Under the meshing transmission of the double-sided toothed plate 41, the drill barrel 2 is drilled into the soil to be collected along the through hole 11.

[0054] Once the predetermined depth is reached, the pressure plate 35 is released. Following the same principle as above, the collar 31 is disengaged from the rotating rod 15. Then, the drive rod 3 is moved to the position of the second toothed ring 6. Following the same principle as the first toothed ring 5, the second toothed ring 6 rotates. Under the meshing transmission action of the double-sided toothed plate 41, the drill barrel 2 is lifted along the through hole 11, and then the collected soil inside the drill barrel 2 is removed.

[0055] Example 2

[0056] The difference between this embodiment and Embodiment 1 is that, Figure 4 , 5 As shown in Figures 6 and 7, the platform 1 is hollow inside, and an arc-shaped hole 17 is provided on the platform 1 located on one side of the drive rod 3. A toothed bar 7 is provided vertically inside the arc-shaped hole 17 located at the position of the first toothed ring 5. The upper end of the toothed bar 7 is hinged to the middle of the drive rod 3. A concave block is provided on the platform 1 at the position where the drive rod 3 and the first toothed ring 5 are connected to enhance the moving stability of the straight rack 71. The side of the straight rack 71 is slidably connected to the concave block.

[0057] like Figure 7 , 8 As shown in Figure 9, the drill barrel 2 has a hollow side wall and a rotating ring 21 is provided inside the cavity. The rotating ring 21 is rotatably connected to the drill barrel 2, and the lower end of the rotating ring 21 extends out of the drill barrel 2 and is provided with several first cutting blades.

[0058] like Figure 6 As shown, the inner bottom surface of the platform 1 is provided with an arc-shaped rack 8 that is slidably connected to it. One side of the arc-shaped rack 8 is provided with a shaft 81 in the vertical direction. The shaft 81 is rotatably connected to the platform 1. The upper end of the shaft 81 is provided with a first bevel gear 82, and the lower end of the shaft 81 is provided with a first spur gear 83 for meshing with the arc-shaped rack 8. One side of the first bevel gear 82 is provided with a second bevel gear 84 that meshes with it. The end face of the second bevel gear 84 is provided with a second spur gear 85 for meshing with the rack 7. The second spur gear 85 is provided with a rotating shaft that is rotatably connected to the inner wall of the platform 1. The arc-shaped rack 8 passes through the platform 1 and the drill cylinder 2 in sequence through a connecting rod 87 and is limited and locked by a vertical sliding groove to the connecting plate 86 provided on the rotating ring 21. The platform 1 and the drill cylinder 2 are both provided with square holes for moving the connecting rod 87.

[0059] like Figure 6 , 8 As shown, the lower inner wall of the drill barrel 2 has three grooves, each groove containing a fan-shaped airbag 22 for unfolding and sealing the bottom of the drill barrel 2. Each fan-shaped airbag 22 contains a folding bracket 23. An arc-shaped airbag 18 is located on the top surface of the platform 1 between the second toothed ring 6 and the toothed rod 7. The arc-shaped airbag 18 is connected to each of the fan-shaped airbags 22 via an air tube.

[0060] like Figure 11 As shown, the folding bracket 23 includes a main rod 231 and a support rod 232. One end of the support rod 232 is hinged to the middle of the main rod 231, and the other end of the support rod 232 abuts against the inner wall of the fan-shaped airbag 22. One end of the main rod 231 is rotatably connected to the fan-shaped airbag 22 located at one end of the groove. The other end of the main rod 231 is attached to the inner wall of the outer side of the fan-shaped airbag 22. A second blade for cutting soil contaminated by waste aluminum ash is provided on the outer wall of the fan-shaped airbag 22. The main rod 231 is an arc-shaped rod with the same curvature as the inner wall of the drill barrel 2.

[0061] like Figure 10 As shown, the rack 7 includes a straight rack 71 and a rod body 72. The straight rack 71 is slidably connected to a vertical groove provided on the rod body 72, and a plurality of springs are provided between the straight rack 71 and the rod body 72.

[0062] The working method of the above-mentioned sample collection device is as follows:

[0063] The working method is basically the same as in Embodiment 1. Based on Embodiment 1, when the drive rod 3 moves to the position of the first gear ring 5, the rack 7 is inserted into the concave block. During the reciprocating swing of the drive rod 3, the rack 7 moves up and down, thereby meshing with the second spur gear 85, which causes the second bevel gear 84 to rotate. Under the meshing transmission of the second bevel gear 84 and the first bevel gear 82, the shaft 81 rotates, thereby driving the first spur gear 83 to rotate, and then the arc rack 8 swings back and forth along the slide rail. During this period, the rack 7 structure can maintain the contact between the spur rack 71 and the second spur gear 85 under the action of the spring.

[0064] During this process, the arc-shaped rack 8 moves the connecting plate 86 back and forth via the connecting rod 87, thereby causing the rotating ring 21 to move back and forth. This assists the drill barrel 2 in drilling downwards via the first blade. During the drilling process, the connecting rod 87 can slide up and down in the guide groove of the connecting plate 86, but its left and right sliding is restricted. This satisfies the requirement that the drill barrel 2 can continuously drill downwards and maintain the drive for the rotating ring 21 to move back and forth. At the same time, considering that soil debris may enter the square hole, commercially available materials such as elastic cloth can be used to cover the square hole to block soil debris without affecting the movement stroke of the connecting rod 87.

[0065] Meanwhile, as the drive rod 3 moves from the first gear ring 5 to the second gear ring 6, the gear rod 7 disengages from the second spur gear 85. When it moves to the vicinity of the second gear ring 6, it compresses the arc-shaped airbag 18. Under compression, the airbags 22 connected to each other expand through the air tube. During the expansion of the fan-shaped airbags 22, the folding bracket 23 unfolds along with the fan-shaped airbags 22, thereby increasing the support strength of the fan-shaped airbags 22. The second blade cuts the soil inside the drill barrel 2 at the edge, thereby accelerating the separation of the soil layers inside the drill barrel 2 and reducing the possibility of soil not being able to be brought out of the drill barrel 2.
