Description

Technical Field

[0001] This invention belongs to the field of soil remediation technology, specifically relating to a device for remediating soil contaminated in mines. Background Technology

[0002] Soil remediation is a technical measure to restore contaminated soil to its normal function. Currently, in the process of remediation of mine-contaminated soil using remediation devices, an injection pipe is inserted into the soil, and then a remediation solution is injected into the soil through the injection pipe for remediation treatment. However, the injection pipe has many outlets for discharging the remediation solution. When the injection pipe is inserted into the soil, it compresses the soil, which can easily cause soil to enter the outlets of the injection pipe, causing blockage and affecting subsequent injection. Furthermore, the compression of the soil can cause compaction, affecting the penetration of the remediation solution and impacting soil remediation. Therefore, we propose a remediation device for mine-contaminated soil. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to address the problems raised in the background art center.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A soil remediation device for contaminated mines includes a vehicle body and a storage tank. The storage tank is located on the left side wall of the top of the vehicle body, and a mounting frame is installed on the right side wall of the top of the vehicle body. A mounting plate is slidably installed inside the mounting frame, and an electric push rod is installed on the top wall of the mounting frame. The electric push rod extends into the inner cavity of the mounting frame and connects to the top wall of the mounting plate. Holes are evenly distributed on the mounting plate, and injection pipes are inserted into the holes. The inner cavity of the injection pipes communicates with the inner cavity of the storage tank through a conduit. A protective sleeve is fitted around the bottom of the outer wall of the injection pipes, and liquid outlets are evenly distributed around the bottom of the outer wall of the injection pipes, with the liquid outlets located inside the inner cavity of the protective sleeve.

[0006] The protective sleeve is slidably fitted onto the bottom of the outer wall of the injection tube via an elastic element. A winding motor is installed on the top of the outer wall of the injection tube, and a pull rope is installed between the outer wall of the output shaft of the winding motor and the top wall of the protective sleeve.

[0007] Both sides of the bottom of the protective sleeve are hinged with baffles by torsion springs, and the top wall of the baffle is in contact with the bottom end of the injection tube.

[0008] The side wall of the injection tube is provided with an installation groove, and a stop block is slidably inserted into the installation groove through an elastic element. The bottom of the stop block is in contact with the top wall of the protective sleeve.

[0009] The protective sleeve and the pull rope are connected by an installation hole. The bottom end of the pull rope is slidably inserted into the installation hole by a connecting spring. A push plate is sleeved on the outer wall of the pull rope. A guide groove is provided on the left side of the injection tube. A pull block is slidably installed on the left side inside the guide groove. The pull block is located directly above the push plate. A connecting rope is installed between the outer wall of the pull block and the elastic element.

[0010] The outer wall of the protective sleeve is evenly provided with mounting slots. A flipping block is slidably connected inside the mounting slot. An electric telescopic rod is provided between the flipping block and the mounting slot. A moving block is provided at the bottom end of the pull rope. The moving block is slidably connected in the mounting hole. A contact switch is provided on the top wall of the moving block. A pressure block is installed at the top of the inner cavity of the mounting hole. The pressure block is located above the contact switch. The contact switch is electrically connected to the electric telescopic rod.

[0011] The protective sleeve includes an installation sleeve with a connecting groove at the bottom. A sleeve body is provided at the bottom of the installation sleeve, and a connecting block is installed at the top of the sleeve body. The cross-section of both the connecting block and the connecting groove is annular. The connecting block is inserted into the connecting groove. Threads are provided on the outer wall of the connecting block and the inner wall of the connecting groove. Conductive plates are provided on the top of the connecting block and the inner top of the connecting groove. The two sets of conductive plates are in contact with each other, and the conductive plate on the upper side is electrically connected to a contact switch, while the conductive plate on the lower side is electrically connected to an electric telescopic rod.

[0012] A cleaning ring block is provided on the inner wall of the sleeve, and the inner wall of the cleaning ring block is in contact with the outer wall of the injection tube.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The device uses a protective sleeve and a baffle to cover the outlet of the injection pipe, so that when the injection pipe is lowered and inserted into the soil, the injection pipe will not come into direct contact with the soil, thus preventing soil from entering the outlet of the injection pipe and preventing blockage of the outlet. This ensures that the remediation solution is injected into the soil normally and guarantees the quality of soil remediation.

[0015] 2. Remove the protective cover. As the rope moves, the moving block will also move upward, causing the contact switch to contact the pressure block and be pressed, energizing the electric telescopic rod. This will push the flipping block outward into the inner cavity of the placement slot, moving it to the outside of the protective cover and inserting it into the soil. As the protective cover moves upward, the flipping block will move in the soil, turning it over and loosening the compacted soil. This allows the remediation fluid to easily penetrate the soil, preventing it from accumulating in one area and ensuring the quality of soil remediation. Attached Figure Description

[0025] Example 1

[0026] like Figure 1-6As shown, the present invention discloses a soil remediation device for mine geological pollution, comprising a vehicle body 1 and a storage tank 2. The storage tank 2 is installed on the left side wall of the top of the vehicle body 1, and contains remediation fluid. A mounting frame 3 is installed on the right side wall of the top of the vehicle body 1, and a mounting plate 5 is slidably installed in the inner cavity of the mounting frame 3. An electric push rod 4 is installed on the top wall of the mounting frame 3, and the bottom moving end of the electric push rod 4 extends into the inner cavity of the mounting frame 3 and connects to the top wall of the mounting plate 5. The outer wall of the mounting plate 5 has evenly spaced openings, and an injection pipe 6 is inserted through the inner cavity of each opening. The top of the inner cavity of the injection tube 6 is connected to the inner cavity of the storage tank 2 through a conduit. The vehicle body 1 is moved to the soil area that needs to be repaired. Then the electric push rod 4 works, causing the mounting plate 5 to move down with the injection tube 6, so that the injection tube 6 is inserted into the soil. Then the repair liquid inside the storage tank 2 is injected into the soil through the conduit and the injection tube 6 to repair the soil. After the injection is completed, the electric push rod 4 moves up with the mounting plate 5 to remove the injection tube 6 from the soil. All electrical equipment involved in the device is electrically connected to an external power switch through wires.

[0027] Please see Figure 2 , Figure 3 and Figure 5 A protective sleeve 7 is fitted onto the bottom of the outer wall of the injection tube 6. Dispensing ports are evenly distributed at the bottom of the outer wall of the injection tube 6, and these ports are located within the inner cavity of the protective sleeve 7. The protective sleeve 7 is slidably fitted onto the bottom of the outer wall of the injection tube 6 via an elastic element. A winding motor 12 is installed at the top of the outer wall of the injection tube 6. A pull rope 11 is installed between the outer wall of the output shaft of the winding motor 12 and the top wall of the protective sleeve 7. Baffles 8 are hinged to the left and right sides of the bottom of the protective sleeve 7 via torsion springs. The top wall of the baffle 8 is in contact with the bottom end of the injection tube 6. The protective sleeve 7 and the baffle 8 work together to... The liquid outlet cover on the outside of the injection tube 6 prevents the injection tube 6 from directly contacting the soil when it is lowered and inserted into the soil, thus preventing soil from entering the liquid outlet of the injection tube 6 and preventing blockage of the liquid outlet. When the injection tube 6 is inserted into the soil, the winding motor 12 is energized and works, winding the pull rope 11 around the output shaft of the winding motor 12, so that the pull rope 11 pulls the protective sleeve 7 upward, moving the protective sleeve 7 and the baffle 8 above the injection tube 6, so that the protective sleeve 7 and the baffle 8 are removed from the soil, exposing the liquid outlet.

[0028] Please see Figure 3 , Figure 4 and Figure 6The front wall of the injection tube 6 has an installation groove, and a stop 16 is slidably inserted into the inner cavity of the installation groove via an elastic element. The bottom wall of the stop 16 fits against the top wall of the protective sleeve 7, blocking the protective sleeve 7 from moving automatically. This ensures that the protective sleeve 7 covers the bottom of the injection tube 6 during insertion into the soil, guaranteeing the effectiveness of the protective sleeve 7. An installation hole 17 is provided at the connection point between the protective sleeve 7 and the pull rope 11. The bottom end of the pull rope 11 is slidably inserted into the inner cavity of the installation hole 17 via a connecting spring. A push-type spring is fitted onto the outer wall of the pull rope 11. The left side wall of the plate 14 and the injection tube 6 is provided with a guide groove 15. A pull block 13 is slidably installed on the left side of the inner cavity of the guide groove 15. The pull block 13 is located directly above the push plate 14. A connecting rope is installed between the outer wall of the pull block 13 and the elastic element. When the protective sleeve 7 needs to be removed, the winding motor 12 works to wind up the pull rope 11, so that the pull rope 11 moves to the outside of the inner cavity of the mounting hole 17 (the pull rope 11 will not be completely removed from the inner cavity of the mounting hole 17), so that the push plate 14 moves up and moves the pull block 13 upward, pulling the connecting rope and moving the stop block 16 into the inner cavity of the mounting groove, so that the restriction on the protective sleeve 7 is removed.

[0029] Example 2

[0030] Based on Example 1, Example 2 differs from Example 1 in that: the outer wall of the protective sleeve 7 is evenly provided with mounting grooves 9, a flipping block 10 is slidably installed in the inner cavity of the mounting groove 9, an electric telescopic rod is installed between the flipping block 10 and the inner cavity of the mounting groove 9, a moving block 18 is installed at the bottom end of the pull rope 11, and the moving block 18 is slidably installed in the inner cavity of the mounting hole 17, and a contact switch 22 is installed on the top wall of the moving block 18. A pressure block 23 is installed at the top of the inner cavity of the mounting hole 17, and the pressure block 23 is located above the contact switch 22. The contact switch 22 and the electric telescopic rod are connected. The pole is electrically connected. During the process of removing the protective sleeve 7 and moving the pull rope 11, the moving block 18 will also move upward, so that the contact switch 22 contacts the pressure block 23 and is pressed, so that the electric telescopic pole is energized and works, pushing the flipping block 10 to the outside of the inner cavity of the placement groove 9, so that the flipping block 10 moves to the outside of the protective sleeve 7 and is inserted into the soil. During the process of the protective sleeve 7 moving upward, the flipping block 10 will move in the soil, turning the soil over, making the compacted soil loose, so that the repair liquid can easily penetrate into the soil, avoiding the repair liquid from accumulating in one area, and ensuring the quality of soil repair.

[0031] Compared to Example 1, the addition of components such as the turning block 10 allows the turning block 10 to be moved to the outside of the protective sleeve 7 and inserted into the soil. As the protective sleeve 7 moves upward, the turning block 10 moves in the soil, turning the soil and loosening the compacted soil, making it easier for the repair liquid to penetrate into the soil and preventing the repair liquid from accumulating in one area.

[0032] Example 3

[0033] Based on Examples 1 and 2, Example 3 differs from Examples 1 and 2 in that: the protective sleeve 7 includes an installation sleeve 71 that is slidably fitted onto the outer wall of the injection tube 6 via an elastic element. The bottom wall of the installation sleeve 71 has a connecting groove 20, and a sleeve body 72 is installed on the bottom wall of the installation sleeve 71. A connecting block 19 is installed on the top wall of the sleeve body 72. Both the connecting block 19 and the connecting groove 20 have annular cross-sections, and the connecting block 19 is inserted into the inner cavity of the connecting groove 20. Both the outer wall of the connecting block 19 and the inner wall of the connecting groove 20 are threaded. Rotating the sleeve body 72 causes the connecting block 19 to move out of the inner cavity of the connecting groove 20, disconnecting the installation sleeve 71 from the sleeve body 72. This allows the sleeve body 72 to be removed for replacement or cleaning and maintenance. Furthermore, after the injection tube 6 is removed from the soil, the winding motor 12 releases the pull rope, and the protective sleeve 7, under the action of the elastic element, will move downwards and reset, scraping off the soil adhering to the outer wall of the injection tube 6.

[0034] The top wall of the connecting block 19 and the top of the inner cavity of the connecting groove 20 are both equipped with conductive plates 21, and the two sets of conductive plates 21 are attached to each other. The upper conductive plate 21 is electrically connected to the contact switch 22, and the lower conductive plate 21 is electrically connected to the electric telescopic rod. The contact switch 22 and the electric telescopic rod are connected by the attachment of the conductive plates 21. A cleaning ring block is installed on the inner wall of the sleeve 72. The cleaning ring block is not shown in the figure and is made of sponge material, which makes the outer wall of the injection tube 6 cleaner. The inner wall of the cleaning ring block is attached to the outer wall of the injection tube 6.

[0035] Compared to Embodiment 2, the installation sleeve 71 and sleeve body 72 are added. By rotating the sleeve body 72, the connecting block 19 is moved out of the inner cavity of the connecting groove 20, and the connection between the installation sleeve 71 and the sleeve body 72 is disconnected, so that the sleeve body 72 can be removed for replacement or cleaning and maintenance.

[0036] Working principle: Move vehicle 1 to the soil area that needs repair. Then, the electric push rod 4 operates, causing the mounting plate 5 to move down with the injection tube 6, inserting the injection tube 6 into the soil. During this process, the protective sleeve 7 and the baffle 8 cooperate to cover the outlet of the injection tube 6, preventing direct contact between the injection tube 6 and the soil when it is inserted into the soil, thus avoiding soil from entering the outlet of the injection tube 6. Then, the winding motor 12 is powered on, winding the pull rope 11 around the output shaft of the winding motor 12, causing the pull rope 11 to pull the protective sleeve 7 upward, moving the protective sleeve 7 and the baffle 8 above the injection tube 6, removing the protective sleeve 7 and the baffle 8 from the soil and exposing the outlet. Then, the repair fluid inside the storage tank 2 is injected into the soil through the conduit and the injection tube 6 to repair the soil. After the injection is completed, the electric push rod 4 moves the mounting plate 5 upward, removing the injection tube 6 from the soil.
