Description

Technical Field

[0001] This utility model relates to the field of ecological restoration, specifically a soil deep remediation device for ecological restoration. Background Technology

[0002] Ecological restoration refers to the process of ceasing human interference with an ecosystem to reduce its load and pressure, relying on the ecosystem's self-regulation and self-organization capabilities to guide its evolution towards order, or utilizing this self-recovery capability of the ecosystem, supplemented by artificial measures, to gradually restore a damaged ecosystem or to guide it towards a virtuous cycle. Soils around rivers and lakes are easily affected by water pollution, especially in some industrialized areas. Pollutants in rivers and lakes can enter the surrounding deep soil through infiltration and other means. For example, acidic wastewater pollution can acidify the soil, leading to soil structure damage, reduced porosity, decreased aeration and permeability, and reduced water and fertilizer retention capacity, thus requiring soil restoration.

[0003] Traditional soil remediation equipment involves many steps and complex processes, from soil extraction and transportation to treatment, and then returning the treated soil to its original location or carrying out further disposal, resulting in a long remediation cycle. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a soil deep remediation device for ecological restoration, which solves the problem of long remediation cycles.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a soil deep remediation device for ecological restoration, comprising a well and a partition, the well and the partition being fixedly connected, a lifting device for controlling the movement of the well being installed at the upper end of the well, a telescopic head being slidably connected at the bottom end of the well, the telescopic head having several slots inside, each slot having a nozzle for rotation inside, the nozzles being controlled to rotate by a transmission mechanism, a fixed bucket being installed inside the well, the fixed bucket being used for lifting and lowering relative to the well, and the inside of the fixed bucket being used for injecting gas or injecting soil remediation agents.

[0006] Several telescopic tubes are installed on the outside of the fixed barrel. The fixed end of the telescopic tube is connected to the fixed barrel, and the free end is slidably connected to a piston. When the air pressure or hydraulic pressure in the telescopic tube exceeds a predetermined value, the piston disengages from the telescopic tube. When it falls below the predetermined value, the piston is reset by a spring mechanism.

[0007] When the nozzle rotates to be parallel with the telescopic tube, the free end of the telescopic tube is inserted into the nozzle by pressurizing the telescopic tube and cooperating with the piston and spring mechanism.

[0008] Preferably, the lifting component includes a lifting lug, an extension rod, and a manhole cover. The two ends of the extension rod are fixedly connected to the lifting lug and the manhole cover, respectively. The manhole cover is installed at the upper end of the manhole and is fixed relative to the manhole.

[0009] Preferably, an electric actuator is installed between the partition and the fixed bucket, and the movement of the fixed bucket is controlled by the electric actuator.

[0010] Preferably, an air pump and a water pump are fixedly installed on the partition. The output ends of the air pump and the water pump are connected to flexible hoses.

[0014] Preferably, the spring mechanism includes a cross, a rod, and a spring B. The cross is fixedly connected to the sliding tube, one end of the rod is slidably connected to the cross, and the other end is fixedly connected to the piston.

[0026] like Figures 1-9As shown, a soil deep remediation device for ecological restoration includes a well 1 and a partition 2. The well 1 and the partition 2 are fixedly connected. A lifting component 3 for controlling the movement of the well 1 is installed at the upper end of the well 1. The lifting component 3 includes a lifting lug, an extension rod, and a well cover. The two ends of the extension rod are fixedly connected to the lifting lug and the well cover, respectively. The well cover is installed at the upper end of the well 1 and is fixed relative to the well 1. The well cover and the well 1 are detachable. By fixing the lifting lug to the lifting rope of an external crane, the entire device is moved by controlling the crane. The bottom end of the well 1 is slidably connected. The device is equipped with a telescopic head 4, which has several slots 5 inside. Each slot 5 contains a rotating nozzle 6. The nozzles 6 are controlled to rotate by a transmission mechanism 18. The transmission mechanism 18 includes several rotating shafts 181, several push plates 182, several sliding rods 183, a lifting plate 184, and a spring A25. One end of the rotating shaft 181 is rotatably connected to the inner wall of the slot 5, and the other end is fixedly connected to the nozzle 6. One end of the lifting plate 184 is fixedly connected to the rotating shaft 181. The other end is rotatably connected to the sliding rod 183. Several grooves are provided inside the lifting plate 184, and the sliding rod 183 is slidably connected to the grooves. The two ends of the spring A25 are fixedly connected to the fixed bucket 7 and the lifting plate 184, respectively. The fixed bucket 7 is installed inside the shaft 1. The fixed bucket 7 is used for lifting relative to the shaft 1, and its interior is used for injecting gas or soil remediation agents. An electric actuator 11 is installed between the partition plate 2 and the fixed bucket 7, and the movement of the fixed bucket 7 is controlled by the electric actuator 11. The partition plate 2 is fixedly equipped with... There are air pump 12 and water pump 13. The output ends of air pump 12 and water pump 13 are connected to hoses 14. The other ends of the two hoses 14 are connected to the fixed bucket 7. The air pump 12 delivers gas to the corresponding hose 14. A medicine tank 15 is fixedly installed on the partition 2. The water inlet of water pump 13 is connected to a water pipe 16. The water pipe 16 is fixedly connected to the medicine tank 15, with one end located inside the medicine tank 15. The water pump 13 delivers the medicine in the medicine tank 15 to the other hose 14 through the water pipe 16.

[0027] Several telescopic tubes 8 are installed on the outside of the fixed barrel 7. Each telescopic tube 8 includes a fixed tube 801, a sliding tube 802, and a sealing ring 803. The fixed tube 801 is fixedly connected to the sealing ring 803, and the sliding tube 802 is slidably connected to the sealing ring 803. The sealing ring 803 ensures that the connection between the sliding tube 802 and the fixed tube 801 remains sealed when the sliding tube 802 moves relative to the fixed tube 801, preventing gas or liquid leakage. A sealing gasket 17 is fixedly connected to one end of the sliding tube 802. One end is made of soft material and the other end is made of hard material. When the sliding tube 802 is inserted into the nozzle 6, the softer end of the sealing gasket 17 seals the sliding tube 802 and the nozzle 6, while the harder end of the sealing gasket 17 presses against the nozzle 6 to position the sliding tube 802. The fixed end of the telescopic tube 8 is connected to the fixed bucket 7, and its free end is slidably connected to the piston 9. When the air pressure or hydraulic pressure in the telescopic tube 8 exceeds a predetermined value, the piston 9 disengages from the telescopic tube 8. When it falls below the predetermined value, the piston 9 is reset by the spring mechanism 10.

[0028] When the nozzle 6 rotates to be parallel with the telescopic tube 8, the telescopic tube 8 is pressurized, and the free end of the telescopic tube 8 is inserted into the nozzle 6 in coordination with the piston 9 and the spring mechanism 10. The spring mechanism 10 includes a cross 101, a rod 102 and a spring B103. The cross 101 is fixedly connected to the sliding tube 802. One end of the rod 102 is slidably connected to the cross 101 and the other end is fixedly connected to the piston 9. The two ends of the spring B103 are fixedly connected to the cross 101 and the piston 9 respectively. One end of the piston 9 is rounded.

[0029] In use, first, a channel large enough to accommodate the well 1 is reserved in the soil. Then, by fixing the lifting lugs to the lifting ropes of an external crane, the well 1 is lowered into the reserved channel by the crane. The initial positions of the telescopic head 4, the transmission mechanism 18, and the nozzle 6 are as follows: Figures 4-6 As shown, the transmission mechanism 18 drives the nozzle 6 to rotate into the slot 5 and the telescopic head 4 retracts into the well 1 under the control of the electric actuator 11. When the well 1 is extended into the reserved channel, it prevents the soil from interfering with the nozzle 6 and prevents the soil from entering the nozzle 6 and the telescopic head 4 during the process.

[0030] Next, after the well 1 is inserted into the soil, its position should be fixed by a crane. Then, the fixed bucket 7 is driven to descend by the electric actuator 11. The fixed bucket 7 drives the spring A25 to descend, which in turn drives the lifting plate 184 to descend. The lifting plate 184 drives the sliding rod 183 to descend, which in turn drives one end of the push plate 182 to rotate around the rotating shaft 181. The other end of the push plate 182 drives the rotating shaft 181 to rotate, which in turn drives the nozzle 6 to rotate, causing the nozzle 6 to press against the inner wall of the well 1. Due to the resistance created by the well 1 on the nozzle 6, the spring continues to descend, pushing the lifting plate 184 to continue descending. The lifting plate 184 drives the push plate 182 to descend, which in turn drives the rotating shaft 181 to descend. The rotating shaft 181 drives the telescopic head 4 to descend, causing the telescopic head 4 to extend from the bottom of the well 1 and press against the inner bottom wall of the soil channel. The channel provides support for the telescopic head 4. Figures 1-3 As shown, since the telescopic head 4 has extended from the bottom of the well 1, the well 1 no longer provides resistance to the nozzle 6. As the fixed barrel 7 continues to descend, one end of the nozzle 6 will rotate out of the slot 5. When the bottom surface of the lifting plate 184 contacts the protruding part on the inner bottom wall of the telescopic head 4, the protruding part on the inner bottom wall of the telescopic head 4 provides support for the lifting plate 184, and the lifting plate 184 no longer moves. At this time, the nozzle 6 should be parallel to the telescopic tube 8. As the fixed barrel 7 continues to descend, the spring A25 is compressed until the protruding part at the bottom of the fixed barrel 7 contacts the lifting plate 184, and the lifting plate 184 provides support for the fixed barrel 7. At this time, the fixed barrel 7 no longer descends, and the telescopic tube 8 on the outside of the fixed barrel 7 should be on the same axis as the nozzle 6, laying the foundation for the docking of the telescopic tube 8 and the nozzle 6.

[0031] Next, gas is supplied to one of the hoses 14 via the air pump 12. The gas enters the fixed tank 7, the fixed tube 801, and the sliding tube 802 in sequence. The piston 9 seals one end of the sliding tube 802, and the spring B103 applies a pulling force to the piston 9 to prevent it from disengaging from the sliding tube 802. The air pressure inside the sliding tube 802 pushes the piston 9 towards the nozzle 6. The piston 9 moves the spring B103 without deformation. The spring B103 moves the cross 101, which in turn moves the sliding tube 802 along the fixed tube 801. At this time, the sliding of the telescopic tube 8... The tube 802 begins to connect with the nozzle 6. During the connection process, the sliding tube 802 and the sealing gasket 17 at the sliding tube 802 are inserted into the nozzle 6. One end of the sealing gasket 17 is made of soft material, which allows the connection between the sliding tube 802 and the nozzle 6 to be sealed. When the other end of the sealing gasket 17 abuts against the nozzle 6, since the other end of the sealing gasket 17 is made of hard material, the nozzle 6 provides resistance to the sealing gasket 17, preventing the sealing gasket 17 and the sliding tube 802 from moving forward again, thus achieving the purpose of positioning the sliding tube 802. At this time, the connection work is completed, and the hose 14, the fixed bucket 7, the telescopic tube 8 and the nozzle 6 are in a state of sequential connection.

[0032] Next, the output power of the air pump 12 is increased so that the air pressure in the telescopic tube 8 overcomes the pulling force of the spring B103 on the piston 9, and the air pressure pushes the piston 9 out of the sliding tube 802. At this time, the gas enters the nozzle 6 and is sprayed onto the soil. By injecting high-pressure air into the soil, a local high-pressure area is formed inside the soil, creating a pressure difference with the surrounding undisturbed soil area. Driven by the pressure difference, the air diffuses to the low-pressure area, promoting the flow of gas between soil particles, opening up narrow pore channels, thereby increasing soil porosity. Then, the agent in the agent tank 15 is transported to the fixed tank 7 by the water pump 13, and then transported to the nozzle 6 along the telescopic tube 8. Finally, the agent is sprayed from the nozzle 6 into the soil. It should be noted that the agent in the agent tank 15 is a chemical remediation agent, such as a microbial agent, which is produced by microorganisms through... Its own metabolic activities, such as degradation and transformation, decompose organic pollutants in the soil into harmless substances. It can also change the soil environment by secreting organic acids and iron carriers, promoting the dissolution or precipitation of heavy metals and reducing their toxicity. Because the gas increases soil porosity, the number of pores increases and the pore size increases, providing more and wider channels for injected agents. When the agent diffuses in the soil, it can more easily enter areas with smaller or blocked pores, thus distributing evenly over a wider area. The increased porosity makes the flow channels inside the soil smoother, reducing the resistance encountered by the agent during injection. This is conducive to the agent flowing more smoothly in the soil under pressure, avoiding the accumulation of agent in local areas due to excessive resistance, thus achieving a more uniform distribution. Moreover, the increased number and larger pore size can further reduce the time required for remediation work.

[0033] Finally, after the repair work is completed, the output of water pump 13 is stopped, and air is pumped out of hose 14 by air pump 12. The air pressure in fixed barrel 7 and telescopic tube 8 decreases. Under the elastic deformation of spring B103, piston 9 begins to reset and inserts into sliding tube 802. As the air pressure in telescopic tube 8 continues to decrease, piston 9 drives sliding tube 802 to disengage from nozzle 6 through spring mechanism 10, and causes sliding tube 802 to retract into fixed tube 801. Then, fixed barrel 7 is driven to rise to its original position by electric push rod 11. Spring A25 pulls lifting plate 184 of transmission mechanism 18 to rise. Spray head 6 is turned into slot 5 by conventional mechanism. Finally, telescopic head 4 retracts into well 1. During the process of lifting well 1 out by crane, soil is prevented from entering telescopic head 4 and nozzle 6.
