[0035] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0036] like Figures 1 to 13As shown, an intelligent underground remediation device for microbial remediation of heavy metal-contaminated soil in one embodiment of the present invention comprises a walking platform 1, and the upper end of the walking platform 1 is rotatably connected to a vehicle body 2. A first mounting plate 3 is fixedly connected to one side of the vehicle body 2, and a drug storage structure 17 is installed on the first mounting plate 3. A connecting structure 5 is installed on the vehicle body 2, and a plurality of drug injection structures 6 are installed on the connecting structure 5. The drug storage structure 17 is used to provide a repair medium to the second electromagnetic block 16. The protruding end of the connecting structure 5 is away from the drug storage structure 17. The drug storage structure 17 and the connecting structure 5 can keep the walking platform 1 and the vehicle body 2 balanced, so that the center of gravity of the walking platform 1 will not be toward one side during the operation of the walking platform 1, so as to avoid the situation that the walking platform 1 topples over during the operation due to the unstable center of gravity of the walking platform 1.

[0037] like Figures 1 to 9 As shown, the connection structure 5 is a multi-stage telescopic rod 501, and a plurality of injection structures 6 are fixedly connected to the multi-stage telescopic rod 501. A mounting structure 7 is installed between the injection structure 6 and the multi-stage telescopic rod 501, and the injection structure 6 can be installed on the multi-stage telescopic rod 501 through the mounting structure 7. Specifically, the mounting structure 7 includes a clamp 8, and when the clamp 8 is not tightened, it can slide on the multi-stage telescopic rod 501 to adjust the position of the injection structure 6. When the clamp 8 is tightened, the clamp 8 can be fixed at a certain position of the multi-stage telescopic rod 501.

[0038] like Figure 8 As shown, in order to further improve the stability of the clamp 8 on the multi-stage telescopic rod 501, a first positioning bolt 801 is also threadedly connected to the clamp 8. The first positioning bolt 801 penetrates the clamp 8 and contacts the outer wall of the multi-stage telescopic rod 501. By increasing the friction between the clamp 8 and the multi-stage telescopic rod 501, the secondary fixation of the clamp 8 is achieved, and the displacement of the clamp 8 caused by the injection structure 6 during the repair operation is reduced, thereby reducing the impact of the displacement of the clamp 8 on the repair effect.

[0039] like Figures 1 to 9 As shown, the injection structure 6 includes a third mounting plate 10, a push rod 11 is fixedly connected to the third mounting plate 10, a mounting seat 14 is fixedly connected to the output end of the push rod 11, and an injection pipe 12 is fixedly connected to the end of the mounting seat 14 away from the push rod 11. By starting the third mounting plate 10, the injection pipe 12 can be driven into the ground, and the repair medium is provided to the injection pipe 12 through the drug storage structure 17, and the repair medium is injected into the ground to achieve the purpose of repairing the heavy metal contaminated soil.

[0040] Specifically, Figures 1 to 9As shown, the hoop 8 is fixedly connected with the second mounting plate 9, the second mounting plate 9 is provided with a first slide groove 901, the third mounting plate 10 is fixedly connected with a slider 1001 matching the first slide groove 901, and the third mounting plate 10 is slidably connected with the first slide groove 901 through the slider 1001. A plurality of first limiting holes 902 are also provided on the side wall of the first slide groove 901, the slider 1001 is provided with a second limiting hole 1002 matching the first limiting hole 902, and the second mounting plate 9 is provided with a second positioning bolt 1003 matching the slider 1001, and the second positioning bolt 1003 passes through the first limiting hole 902 and is threadedly connected with the second limiting hole 1002, so as to achieve the purpose of fixing the third mounting plate 10. By sliding the third mounting plate 10, the vertical height of the injection structure 6 can be changed, and the injection structure 6 can be used for heavy metal contaminated soils of different depths. That is, the more the third mounting plate 10 moves upward, the shallower the depth of the injection tube 12 is sunk into the ground, and the more the third mounting plate 10 moves downward, the deeper the depth of the injection tube 12 is sunk into the ground. The depth of the injection tube 12 sunk into the ground can be changed without adjusting the push rod 11, and the operation is simple and convenient.

[0041] like Figures 1 to 9 As shown, the drug storage structure 17 includes a drug storage tank 18, in which the repair medium is stored. A first drug delivery pipe 19 is installed on the drug storage tank 18. The first drug delivery pipe 19 is arranged along the direction in which the first electromagnetic block 15 is arranged, and the first drug delivery pipe 19 is a telescopic pipe that can change according to the change of the multi-stage telescopic rod 501. A plurality of drug delivery branches 20 are fixedly connected to the first drug delivery pipe 19, and a drug delivery structure 21 is installed between the drug delivery branches 20 and the mounting seat 14. The repair medium in the first drug delivery pipe 19 can be delivered to the mounting seat 14 through the drug delivery structure 21, and then the mounting seat 14 delivers the repair medium to the drug injection pipe 12.

[0042] like Fig.10 As shown, the medicine storage tank 18 is provided with a dosing port 1801, through which the repair medium can be added to the medicine storage tank 18. The medicine storage tank 18 is also provided with an observation window 1802, through which the remaining amount of the repair medium in the medicine storage tank 18 can be observed. The remaining amount of the repair medium can be used to determine how much land the repair equipment can continue to repair, thereby determining whether it is necessary to add repair medium to the medicine storage tank 18.

[0043] Specifically, Figure 4As shown, the medicine delivery structure 21 includes a connector 22, and the connector 22 and the medicine delivery branch pipe 20 are threadedly connected. One end of the connector 22 is fixedly connected to the second medicine delivery pipe 23, and the end of the second medicine delivery pipe 23 away from the connector 22 is fixedly connected to the third medicine delivery pipe 24. The third medicine delivery pipe 24 is a hard pipe, and the third medicine delivery pipe 24 is vertically arranged on the third mounting plate 10, parallel to the direction in which the push rod 11 is arranged. The fourth medicine delivery pipe 25 is slidably connected in the third medicine delivery pipe 24. When the push rod 11 pushes the mounting seat 14 to move downward, the fourth medicine delivery pipe 25 will slide downward with the mounting seat 14 to facilitate the delivery of the repair medium, and by setting the third medicine delivery pipe 24 and the fourth medicine delivery pipe 25, it is not easy to cause the situation of pipe entanglement.

[0044] like Figure 5 to Figure 7 As shown, an anti-blocking structure is also provided in the injection pipe 12, and the anti-blocking structure can block the injection pipe 12 when the injection pipe 12 is inserted into the ground, so as to prevent soil and the like from entering the injection pipe 12 and causing the injection pipe 12 to be blocked. Specifically, a plurality of evenly distributed injection holes 1201 are provided on the injection pipe 12, and a connecting rod 13 runs through the injection pipe 12, and a drill bit 1301 matching the injection pipe 12 is fixedly connected to one end of the connecting rod 13, and the drill bit 1301 is located at the lowermost end of the injection pipe 12. A plurality of anti-blocking columns 1302 matching the injection holes 1201 are also fixedly connected to the connecting rod 13, and the anti-blocking columns 1302 can block the injection holes 1201.

[0045] Furthermore, Figure 5 to Figure 7 As shown, one end of the connecting rod 13 is located in the mounting seat 14, and a second slide groove 1401 matching the connecting rod 13 is opened on the mounting seat 14, a second electromagnetic block 16 is fixedly connected to a side wall of the second slide groove 1401, and a first electromagnetic block 15 matching the second electromagnetic block 16 is fixedly connected to the connecting rod 13. When the push rod 11 performs the pushing action, the second electromagnetic block 16 and the first electromagnetic block 15 repel each other, the connecting rod 13 moves to the end away from the second electromagnetic block 16, and the anti-blocking column 1302 can completely block the injection hole 1201, and the drill bit 1301 can be easily drilled into the ground. When the push rod 11 stops pushing, the second electromagnetic block 16 and the first electromagnetic block 15 are attracted to each other, and the connecting rod 13 moves to the end close to the second electromagnetic block 16, and the injection hole 1201 leaks. At this time, the drug storage structure 17 outputs the repair medium, and the repair medium enters the injection pipe 12 through the drug delivery structure 21 and the mounting seat 14 in turn, and is then discharged into the soil through the injection hole 1201 to achieve the repair of heavy metal contaminated soil.

[0046] The repair medium is a repair fluid containing microorganisms.

[0047] like Figure 1 to Figure 3As shown, the first mounting plate 3 is also fixedly connected with a control box 4, through which intelligent control can be realized, and remote control can be realized according to the Internet of Things module. Specifically, the connection structure 5 is also fixedly connected with an ultrasonic detection structure 26, which can be composed of a plurality of ultrasonic detectors. The ultrasonic detection structure 26 detects the situation deep underground and detects whether there are stones underground that will affect the injection structure 6 to be inserted into the ground. If stones or other impurities are found to be affected, it can be linked with the control box 4 to change the position of the walking platform 1, so that the walking platform 1 can stop at a position not affected by stones or other impurities, and perform underground repair operations through the injection structure 6.

[0048] When using, Figure 11 to Figure 13 As shown, first, according to the situation of heavy metal contaminated soil, by loosening the clamp 8, the clamp 8 is slid and changed on the multi-stage telescopic rod 501, the spacing of the injection points is changed, and the clamp is tightened after the spacing of the injection points is changed. Then the injection depth is determined, and the injection depth is changed by changing the stroke of the push rod 11 or the position of the third mounting plate 10 in the second mounting plate 9. That is, the second positioning bolt 1003 is removed, and the third mounting plate 10 is slid in the first slide groove 901 to change the position of the third mounting plate 10. When the position of the third mounting plate 10 changes, the height of the injection structure 6 also changes accordingly. When the stroke of the push rod 11 remains unchanged, the injection depth of the injection structure 6 will change. After the position of the third mounting plate 10 is confirmed, the second positioning bolt 1003 is passed through the first limiting hole 902 and threadedly connected to the second limiting hole 1002. After the injection depth and the spacing of each injection structure 6 are confirmed, the repair operation can be carried out. The repair device is started directly through the control box 4. The repair device can move forward for a certain distance and then stop, and perform an injection action, and then move forward again and stop, and perform the injection action, and perform reciprocating execution to achieve automated repair.

[0049] When the ultrasonic detection structure 26 detects that there is an obstacle affecting the repair equipment in repairing the soil, it can change the forward distance, by moving forward more or shorter, so as to avoid the obstacle under the soil, and perform the injection action to complete the soil repair.

[0050] The present invention can perform automated soil remediation by providing a walking platform 1, a vehicle body 2, a connecting structure 5 and a drug injection structure 6, and an anti-blocking structure is provided on the drug injection structure 6, so that the drug injection pipe 12 is not blocked when the drug injection structure 6 is inserted into the ground, thereby achieving maintenance-free drug injection pipe 12, convenient operation, and helping to improve the efficiency of soil remediation. By providing a drug storage structure 17, it is possible to repair vast areas of soil, and during the operation of the repair equipment, only the repair medium needs to be added manually. By providing an ultrasonic detection structure 26, the repair equipment can avoid underground obstacles that affect soil remediation, and avoid underground obstacles affecting the normal operation of the repair equipment.

[0051] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0052] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
