A connecting straight rod 10 is threadedly connected to the inner wall of the internal thread groove 9, and an electric control valve 11 is fixedly installed on the surface of the connecting straight rod 10. An extraction tube 12 is fixedly connected to one end of the connecting straight rod 10. A side frame 13 is fixedly connected to the right side of the multiphase extraction and repair device 1 near its bottom, and an anti-slip groove 14 is provided on the surface of the side frame 13. An anti-slip card plate 15 is clamped on the inner wall of the anti-slip card groove 14, and a splint 16 is fixedly connected to the surface of the anti-slip card plate 15.

[0027] Furthermore, the main body of the extraction tube 12 is a sealed tube, and an electric cylinder 23 is fixedly installed on the top of the inner wall of the sealed tube. The output end of the electric cylinder 23 is fixedly connected to a sealing push plate 24, and the bottom end of the extraction tube 12 is fixedly connected to an external expansion tube 25. If the extraction tube 12 is blocked by sediment during the extraction process, the electric cylinder 23 can be operated to drive the sealing push plate 24 to move, and when the electric control valve 11 is closed, the extraction tube 12 is pushed in the opposite direction to squeeze out the flowing liquid blockage.

[0028] Furthermore, a dust cover 26 is fixedly connected to the inner wall of the movable groove, and the surface of the dust cover 26 is fixedly connected to the surface of the diversion tube 7 . The dust cover 26 can provide dust protection for the inside of the adjustment frame 2 .

[0031] Working principle: When the multiphase extraction device for groundwater pollution remediation is in use, the multiphase extraction and remediation device 1 can be operated to move it to a suitable water pollution remediation position. However, due to different ground surfaces, the angles for insertion are different. For example, if there are uneven positions and soft soil collapse areas in the soil surface, the first electric telescopic rod 17 can be operated to drive the stabilizing plate 18 to move forward and backward, and the second electric telescopic rod 19 can be operated to drive the lower pressure plate 20 to move, so that the positioning cone 22 on the lower pressure plate 20 can be inserted into the soil surface. The anti-sticking plate 21 is added to avoid the situation where the soil is sticky and picked up when in contact with the ground. The four lower pressure plates 20 in front, back, left and right can be telescopically adjusted to different heights and lengths. Due to different inlet depths and inlet inclinations, the driving motor 5 is operated to drive the rotating frame 6 to rotate, so that the rotation of the rotating frame 6 can drive the diverter pipe 7 to adjust its tilt. Under the action of the stretching hose 8, It can facilitate the stable steering adjustment of the diverter pipe 7 and the feed pipe 3, the internal thread groove 9 can be used to make a threaded sealing connection of the connecting straight rod 10, and the internal liquid flow of the connecting straight rod 10 is controlled by the electric control valve 11. If the extraction pipe 12 is blocked by sediment during the extraction process, the electric cylinder 23 can be operated to drive the sealing push plate 24 to move, and when the electric control valve 11 is closed, the reverse push in the extraction pipe 12 is performed to squeeze out the flowing liquid blockage. When the multi-phase extraction and repair device 1 is not in use, the two clamping plates 16 can be used to abut and clamp the extraction pipe 12, and the addition of the anti-skid abutment pad 27 can avoid the shaking of the extraction pipe 12 during the movement of the multi-phase extraction and repair device 1. Through the setting of the anti-skid groove 14 and the anti-skid clamping plate 15, the clamping plate 16 can be freely disassembled and assembled on the side frame 13, ensuring the water pollution repair effect at different insertion angles under different geological environments.
