Description

Technical Field

[0001] This application relates to the field of soil remediation, and in particular to a comprehensive soil remediation device and system covering all regions. Background Technology

[0002] Soil management is a crucial part of modern agricultural production. Applying healthy soil management techniques to agricultural production can effectively increase crop yields, thereby achieving better economic benefits. Soil management typically includes methods such as increasing soil fertility, increasing soil moisture, and loosening the soil.

[0003] Currently, soil remediation typically employs large, mobile devices such as soil remediation units, which inject remediation fluid into the soil. However, this method is not only costly but also severely limited by terrain. To address this, existing technology provides a soil remediation device that can roll naturally on the soil surface. This device includes a spherical body and multiple injection heads evenly distributed on the spherical body. As the spherical body rolls on the soil, the injection heads insert into the soil and inject remediation fluid, achieving the purpose of soil remediation.

[0004] However, because the spherical body needs to roll on the soil, the injection head on the spherical body is difficult to penetrate deep into the soil. This often prevents the remediation fluid from reaching the deep soil, resulting in only the surface soil being treated and the treatment quality being poor. Summary of the Invention

[0005] In order to improve the quality of soil remediation, firstly, this application provides a comprehensive soil remediation device covering the entire region.

[0006] The comprehensive soil remediation device for all regions provided in this application adopts the following technical solution:

[0007] The device includes a sleeve, a reagent tank, an end cap, and an injection head. The reagent tank is mounted on the end cap, and the end cap is connected to one end of the sleeve by a threaded connection. The injection head is located inside the sleeve and slides with the sleeve. The end cap has a reagent channel that communicates with the reagent tank. The injection head can communicate with the end of the reagent channel on the end cap away from the reagent tank. The end cap can push the injection head to move away from the end cap inside the sleeve. The injection head is used to inject the reagent in the reagent tank into the soil.

[0008] By adopting the above technical solution, the end of the sleeve furthest from the end cap is inserted into the soil. Then, the end cap is screwed on, causing the agent channel on the end cap to gradually approach the injection head inside the sleeve until the agent channel connects with the injection head inside the sleeve. At this time, the end cap, due to its threads, approaches the injection head, thus pushing the injection head out of the sleeve and connecting it with the soil. The remediation liquid in the agent tank is then injected into the soil through the agent channel and the injection head to remediate the deep layers of the soil, thereby improving the quality of soil remediation.

[0009] Optionally, a sealing element is provided at one end of the drug channel near the injection head. The sealing element is connected to the drug channel on the end cap by a threaded connection and communicates with the drug channel. A sealing membrane is provided on the sealing element. After the injection head drills through the sealing membrane, it can communicate with the drug channel.

[0010] By adopting the above technical solution, the sealing film on the plugging component ensures that the repair fluid in the medicine tank will not easily leak from the medicine channel when the plugging component on the end cap is in contact with the injection head. The plugging component and the medicine channel on the end cap are connected by a threaded connection, which allows the plugging component to be replaced at any time, reducing unnecessary waste of resources.

[0011] Optionally, the injection head includes a sliding block, a puncture part, and an injection part. The sliding block is located inside the cannula and slides in cooperation with the inner wall of the cannula. The puncture part is located on the side of the sliding block near the end cap and is used to puncture the sealing membrane. The injection part is located on the side of the sliding block away from the end cap, and an injection channel is provided between the injection part and the puncture part.

[0012] By adopting the above technical solution, the sliding part is inside the sleeve and slides in cooperation with the inner wall of the sleeve. This allows the end cap to push the sliding part out of the sleeve while it is threadedly connected to the sleeve. Before the end cap abuts against the sliding part, as the end cap approaches the sliding part, the puncture part on the sliding part will puncture the sealing film on the sealing element and abut against the sealing element. This allows the repair fluid in the medicine tank to flow along the medicine channel to the puncture part and flow out from the injection part through the injection channel connecting the puncture part and the injection part. This realizes the movement of the injection head inside the sleeve and the connection with the medicine channel.

[0013] Optionally, an anti-pull-out assembly is provided at the end of the sleeve away from the end cap. The anti-pull-out assembly includes a connector and multiple anti-pull-out components, which are distributed on the connector. The connector is connected to the sleeve, and each anti-pull-out component is hinged to the connector. A torsion spring is provided at the hinge point between the anti-pull-out component and the connector. The anti-pull-out component includes a fixedly connected actuating part and an anti-pull-out part. The actuating part is located inside the sleeve, and the distance between the actuating part and the inner wall of the sleeve gradually increases from the direction closer to the torsion spring to the direction away from the torsion spring. A driving part is provided on the side of the sliding block near the anti-pull-out part. When the driving part drives the actuating part to rotate in the sleeve towards the direction closer to the sleeve axis, the actuating part rotates outside the sleeve towards the direction away from the sleeve axis.

[0014] By adopting the above technical solution, when the sliding block moves towards the pull-out component inside the sleeve under the drive of the end cap, the driving part on the sliding block abuts against the end of the pull-out component located inside the sleeve, causing the pull-out component to be driven around the hinge axis, thereby causing the end of the pull-out component located outside the sleeve to rotate in a direction away from the sleeve axis, making it difficult for the sleeve to be pulled out of the soil and reducing the risk of the sleeve tipping over when it is inserted into the soil.

[0015] Optionally, the end of the pull-out section away from the torsion spring is provided with a barb to increase the friction between the pull-out section and the soil.

[0016] By adopting the above technical solution, the barbs on the pull-out section will insert into the soil when the pull-out section rotates away from the casing axis, further increasing the stability of the casing in the soil.

[0017] Optionally, a slot is provided on the outer wall of the injection part, and when the actuating part rotates, the end of the actuating part away from the torsion spring is engaged in the slot.

[0018] By adopting the above technical solution, when it is necessary to remove the cannula, the end cap can be reversed so that the end cap no longer abuts against the injection head, thereby allowing the injection part to retract from the outside of the cannula into the inside of the cannula. This ensures that the injection head is not exposed outside the cannula after the cannula is removed, thus protecting the injection head during transportation.

[0019] Optionally, the outer wall of the sleeve is provided with scale lines, and the values ​​of the scale lines gradually increase from the end away from the end cap to the end closer to the end cap.

[0020] By adopting the above technical solution, staff can determine the depth of the casing in the soil by reading the corresponding scale value on the scale line on the outer wall of the casing.

[0021] Secondly, this application also provides a comprehensive soil remediation system for the entire region, which adopts the aforementioned comprehensive soil remediation device for the entire region, including an infusion pipeline network, a storage tank, a main pipeline, and multiple comprehensive soil remediation devices for the entire region. One end of the main pipeline is connected to the storage tank, and the other end of the main pipeline is connected to the infusion pipeline network. Multiple comprehensive soil remediation devices for the entire region are evenly distributed on the infusion pipeline network, and the infusion pipeline network is connected to the reagent tank.

[0022] By adopting the above technical solution, multiple comprehensive soil remediation devices for the entire region are installed on the infusion pipeline network. The storage tank delivers the remediation solution to the multiple comprehensive soil remediation devices connected to the infusion pipeline network through the infusion pipeline network, which can achieve soil remediation over a wider area and improve the efficiency of soil remediation.

[0023] In summary, this application includes at least the following beneficial technical effects:

[0024] 1. By inserting the end of the sleeve furthest from the end cap into the soil, and then twisting the end cap, the agent channel on the end cap gradually approaches the injection head inside the sleeve until the agent channel connects with the injection head inside the sleeve. At this point, the injection head is pushed out of the sleeve by the end cap and inserted deep into the soil. The remediation solution in the agent tank is then injected into the soil through the agent channel and the injection head to remediate the deep layers of the soil, thereby improving the quality of soil remediation.

[0025] 2. By installing multiple integrated soil remediation devices across a wide area on the infusion pipeline network, and by having the storage tank deliver the remediation solution to the multiple integrated soil remediation devices connected to the infusion pipeline network, soil remediation over a wider area can be achieved, thereby improving the efficiency of soil remediation.

[0026] 3. By setting a torsion spring at the hinge shaft of the pull-out member and the connector, after the soil treatment is completed, the end cap is reversed, and the pull-out member will reset on the connector, so that the sleeve can be smoothly pulled out of the soil. At this time, due to the rotation of the pull-out member on the connector, the soil deep in the sleeve insertion position will be relatively loose after the sleeve is pulled out, thereby achieving the effect of loosening the soil at the same time after the land is treated.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] Example 1:

[0034] This application discloses a comprehensive soil remediation device covering an entire region, referring to... Figure 1 and Figure 2 The device includes a cannula 1, a reagent tank 2, an end cap 3, and an injection head 4. The reagent tank 2 is fixedly connected to the end cap 3, which is installed at the end of the cannula 1 by means of a threaded connection. The injection head 4 is located inside the cannula 1. An anti-pull-out component 12 is provided at the end of the cannula 1 away from the end cap 3. When the end cap 3 is not tightened to the cannula 1, the anti-pull-out component 12 abuts against the injection head 4, so that the injection head 4 will not easily slide out of the cannula 1. When the end cap 3 is tightened to the cannula 1, the injection head 4 will extend out of the cannula 1, and the anti-pull-out component 12 will play an anti-pull-out role for the cannula 1.

[0035] A medicine channel 5 communicating with the medicine tank 2 is provided on the end cap 3. A sealing member 6 is provided at the other end of the medicine channel 5. One end of the sealing member 6 is provided with an external thread, and the inner wall of the end of the medicine channel 5 away from the medicine tank 2 is provided with an internal thread. The sealing member 6 and the medicine channel 5 on the end cap 3 are sealed and connected by the threaded engagement, and the sealing member 6 is connected to the medicine channel 5. A sealing membrane 7 is provided at the end of the sealing member 6 away from the medicine channel 5. When the sealing membrane 7 is in a good condition, the repair fluid in the medicine tank 2 will not leak out from the sealing member 6.

[0036] The injection head 4 includes a sliding block 8, a puncture part 9, and an injection part 10. The sliding block 8 is located inside the cannula 1 and slides against the inner wall of the cannula 1. The puncture part 9 is located on the side of the sliding block 8 near the end cap 3, and the injection part 10 is located on the side of the sliding block 8 away from the puncture part 9. An injection channel 11 is provided between the puncture part 9 and the injection part 10. This allows the sealing member 6 on the end cap 3 to gradually move closer to the puncture part 9 as the end cap 3 is gradually tightened on the cannula 1. After the sealing member 6 and the puncture part 9 come into contact, the puncture part 9 will puncture the sealing membrane 7 on the sealing member 6. A sealing ring is installed on the outer wall of the puncture part 9. Therefore, after the puncture part 9 punctures the sealing membrane 7, the repair fluid in the medicine tank 2 will not easily seep out from the gap between the sealing member 6 and the puncture part 9.

[0037] The repair fluid in the reagent tank 2 flows through the reagent channel 5, then through the injection channel 11, and finally through the injection part 10 on the injection head 4, thereby injecting the repair fluid into the soil. At the same time, as the sealing part 6 and the puncture part 9 come into contact, the injection part 10 is also pushed out from the sleeve 1.

[0038] The pull-out resistant assembly 12 includes a connector 13 and multiple pull-out resistant components 14. The connector 13 is a ring-shaped metal part. The connector 13 is connected to the end of the sleeve 1 away from the end cap 3 by a threaded connection. The multiple pull-out resistant components 14 are evenly distributed on the connector 13 and are hinged to the connector 13. A torsion spring 15 is also provided at the hinge point between each pull-out resistant component 14 and the connector 13. The pull-out resistant component 14 is a non-standard manufactured metal part. The pull-out resistant component 14 includes a fixedly connected actuating part 16 and a pull-out resistant part 17. The actuating part 16 is located inside the sleeve 1, and the end of the actuating part 16 abuts against the sliding block 8 to prevent the sliding block 8 from sliding out of the sleeve 1. The pull-out resistant part 17 is located outside the sleeve 1.

[0039] Reference Figure 2 and Figure 3 A drive unit 21 is also provided on the side of the sliding block 8 where the injection part 10 is provided. The drive unit 21 is distributed at the edge of the sliding block 8. The distance between the actuating part 16 and the inner wall of the sleeve 1 gradually increases from the direction close to the torsion spring 15 to the direction away from the torsion spring 15. This causes the drive unit 21 to enter the gap between the actuating part 16 and the inner wall of the sleeve 1 when the end cap 3 is gradually tightened with the sleeve 1. The drive unit 21 squeezes the actuating part 16, causing the actuating parts evenly distributed on the connector 13 to start rotating around the axis of the hinge. At this time, the pull-out resistance parts 17 all rotate in the direction away from the axis of the sleeve 1, thereby increasing the pull-out resistance of the sleeve 1 in the soil.

[0040] Furthermore, a slot 19 is provided on the outer wall of the injection section 10. When the actuating part 16 is pressed into the sleeve 1 by the driving part 21 and rotates in the direction of the sleeve 1 axis, the end of the actuating part 16 will be located in the slot 19. This allows the actuating part 16 to be automatically reset under the action of the torsion spring 15 simply by rotating the end cap 3 in the opposite direction. As a result, the injection section 10 will rise back in the sleeve 1. This ensures that when the expected repair is completed and transportation is required, the injection section 10 will not be located outside the sleeve 1, reducing the risk of the injection section 10 being damaged during transportation.

[0041] Furthermore, a barb 18 is provided on the pull-out part 17, which allows the barb 18 to be inserted into the soil when the pull-out part 17 rotates around the axis at the hinge point with the connector 13, thereby increasing the stability of the sleeve 1 when it is inserted into the soil.

[0042] Reference Figure 1 A scale line 20 is also provided on the outside of the sleeve 1. The value of the scale line 20 gradually increases from the end of the sleeve 1 away from the end cap 3 to the end of the sleeve 1 closer to the end cap 3. This allows the staff to know the depth of the sleeve 1 in the soil based on the value on the scale line 20, thereby knowing the injection depth of the repair fluid and achieving a better repair effect.

[0043] The implementation principle of this application embodiment is as follows: First, a pit is dug at the target area to be treated. Then, the end of the sleeve 1 equipped with the anti-pull-out component 12 is buried in the pit. The burial depth of the sleeve 1 is confirmed according to the scale line 20 on the sleeve 1. Then, the end cap 3 is screwed. As the end cap 3 is screwed, the sealing member 6 connected to the end cap 3 gradually approaches the puncture part 9. When the puncture part 9 punctures the sealing film 7 on the sealing member 6, the sealing member 6 further pushes the sliding block 8 to slide inside the sleeve 1. The driving part 21 on the sliding block 8 then squeezes the actuating part 16. The actuating part 16 moves towards the axis of the sleeve 1, while the anti-pull-out part 17 moves away from the axis of the sleeve 1, thereby increasing the anti-pull-out resistance of the sleeve 1 in the soil. When the end cap 3 is screwed to the limit position, the injection part 10 extends out of the sleeve 1 and inserts into the soil at the target depth. At this time, the end of the actuating part 16 is located in the groove 19 on the outer wall of the injection part 10.

[0044] Once the soil remediation in the current area is completed, turn the end cap 3 in the opposite direction. The actuating part 16 tends to return to its original position under the action of the torsion spring 15, which in turn drives the sliding block 8 to rise back in the sleeve, so that the injection part 10 is retracted into the sleeve 1. Finally, the sleeve 1 can be pulled out of the soil.

[0045] Example 2:

[0046] Reference Figure 4 Embodiment 2 of this application also provides a comprehensive soil remediation system covering an entire region, including an infusion pipeline network 22, a storage tank 23, and multiple comprehensive soil remediation devices provided in Embodiment 1 above. The storage tank 23 is connected to the infusion pipeline network 22, and the reagent tanks 2 of multiple comprehensive soil remediation devices are all connected to the infusion pipeline network 22. This allows the remediation liquid in the outlet tank to enter the reagent tanks 2 of each comprehensive soil remediation device through the infusion pipeline network 22, and then be transported into the soil through the reagent tanks 2 to remediate the soil, thereby treating and remediating a wider area of ​​soil.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
