Description

Technical Field

[0001] The utility model relates to the technical field of soil remediation, and more particularly to an in-situ remediation device for contaminated soil. Background Art

[0002] Soil remediation refers to the use of a series of technical means and methods to render contaminated soil harmless, reduce its volume and recycle it as a resource in order to restore the health and function of the soil. The purpose of contaminated soil remediation is to eliminate or reduce the content of harmful substances in the soil so that the soil can be reused for agriculture, industry, residence or other purposes.

[0003] A remediation device is a device that injects drugs into contaminated soil to repair the soil in situ. However, in actual use, the connecting pipe of the existing soil remediation device is prone to rotate with the drill pipe. When the drill bit is inserted into the soil, the soil may block the drug outlet hole, thereby affecting the injection efficiency to a certain extent. If the soil enters the drill pipe, it is easy to contaminate the remediation fluid. At the same time, the drill pipe structure of the existing remediation device is simple and the drilling efficiency is low. Utility Model Content

[0030] In this embodiment, when performing in-situ soil repair, the vehicle frame 2 is moved to the repair site, and then the first motor 16 is started. The first motor 16 drives the first bevel gear 17 to rotate, and then drives the second bevel gear 18 to rotate. The moving block 5 moves in the moving groove 4, and then adjusts the height of the moving plate 6. The spiral cone head 19 and the shovel plate 20 are used to facilitate the downward excavation of the drill rod 7. The direction of the connecting pipe 11 is fixed by the fixing rod 29 to prevent the connecting pipe 11 from rotating with the drill rod 7. The connecting hose 28 is used to facilitate the extension of the length of the connecting pipe 11. Subsequently, the water pump 10 is used to pressurize the repair fluid in the liquid storage tank 9 through the connecting pipe 11 and inject it into the drill rod 7. The repair fluid squeezes the control block 14 and compresses the control spring 15, leaking out of the liquid outlet trough 13, so that the repair fluid is discharged through the liquid outlet trough 13 to repair the soil.

[0031] See also Figure 2-3 As an implementation method of the movable plate 6: an adjusting plate 23 is symmetrically fixed on the support plate 3, an adjusting screw 24 is rotatably provided between the adjusting plates 23, an adjusting block 25 is threadedly connected to the adjusting screw 24, an adjusting rod 26 is hinged between the adjusting block 25 and the movable plate 6, a second motor 27 is provided on one side of the adjusting plate 23, and the motor shaft of the second motor 27 is fixedly connected to the adjusting screw 24, a connecting hose 28 is provided on the connecting pipe 11, and a fixing rod 29 is provided on one side of the connecting pipe 11.

[0032] More specifically, when adjusting the height of the movable plate 6, the second motor 27 is started, the second motor 27 drives the adjusting screw 24 to rotate, the adjusting screw 24 drives the adjusting block 25 to move in the opposite direction, and then drives the adjusting plate 23 to rotate, so that the movable plate 6 drives the movable block 5 to move in the movable groove 4, and then the drill rod 7 and the spiral blade 8 drill downward.

[0033] In summary, when the overall equipment is in use or running: when performing in-situ soil repair, the frame 2 is moved to the repair site, and then the first motor 16 is started. The first motor 16 drives the first bevel gear 17 to rotate, and then drives the second bevel gear 18 to rotate. The moving block 5 moves in the moving groove 4, and then adjusts the height of the moving plate 6. The spiral cone head 19 and the shovel plate 20 are used to facilitate the downward excavation of the drill rod 7. The direction of the connecting pipe 11 is fixed by the fixing rod 29 to prevent the connecting pipe 11 from rotating with the drill rod 7. The connecting hose 28 is used to facilitate the extension of the length of the connecting pipe 11. Then, through the action of the water pump 10, the repair liquid in the liquid storage tank 9 is pressurized and injected into the drill rod 7 through the connecting pipe 11. The repair liquid squeezes the control block 14 and compresses the control spring 15, leaking out of the liquid outlet trough 13, so that the repair liquid is discharged through the liquid outlet trough 13 to repair the soil.

[0034] When adjusting the height of the movable plate 6, the second motor 27 is started, and the second motor 27 drives the adjusting screw 24 to rotate, and the adjusting screw 24 drives the adjusting block 25 to move in the opposite direction, thereby driving the adjusting plate 23 to rotate, so that the movable plate 6 drives the movable block 5 to move in the movable groove 4, thereby causing the drill rod 7 and the spiral blade 8 to drill the soil downward.
