[0023] The inner wall of the cleaning cylinder 7 is provided with an annular groove 8, and an annular component 9 is fixedly installed in the annular groove 8. Eight nozzles 10 are installed at equal intervals on the inner circular wall of the annular component 9, and the eight nozzles 10 are connected to each other. The inner wall of the cleaning cylinder 7 is provided with four sliding grooves 20 at equal intervals. The sliding grooves 20 are located above the annular groove 8 and the four sliding grooves 20 are at the same height. A slider 21 is slidably connected in the sliding grooves 20. Both the sliding grooves 20 and the sliders 21 are rectangular structures. One end of the slider 21 extends out of the sliding groove 20. An arc plate 22 is fixedly installed at the extended end of the slider 21. The initial positions of the four sliders 21 are connected. A brush 23 is fixedly installed at the end of the arc plate 22 away from the slider 21.

[0024] As a preferred option, side plates 1 are welded to both ends of the mounting plate 2. The length of the side plates 1 is longer than the length of the mounting plate 2. Two movable wheels 19 are symmetrically installed at the bottom of the side plates 1, and the two movable wheels 19 are arranged in the front-back direction.

[0025] As a preferred embodiment, the top of the side plate 1 is further fixedly mounted with a column 14 by bolts. A connecting plate 15 is fixedly mounted between the two columns 14. The two columns 14 are symmetrically arranged. The connecting plate 15 is close to the top of the two columns 14. Two sliding rods 3 are symmetrically fixedly mounted between the connecting plate 15 and the mounting plate 2. A lifting plate 5 is slidably fitted between the two sliding rods 3. A screw 4 is rotatably connected between the mounting plate 2 and the connecting plate 15. The screw 4 is located between the two sliding rods 3. The lifting plate 5 is threaded onto the outer wall of the screw 4. The top of the screw 4 extends rotatably through the connecting plate 15. A knob 16 is fixedly mounted on the top of the screw 4.

[0026] As a preferred option, a spraying rod 6 is fixedly installed at the top of the lifting plate 5. The bottom end of the spraying rod 6 extends through the lifting plate 5. The spraying rod 6 is adapted to the center hole of the cleaning cylinder 7. The spraying rod 6 and the center hole of the cleaning cylinder 7 are arranged opposite each other in the vertical direction.

[0027] As a preferred embodiment, the spraying rod 6 is located near the front of the lifting plate 5. The top of the lifting plate 5 is fixedly mounted with a delivery pump 17 by bolts. The delivery pump 17 is located near the rear of the lifting plate 5. The top of the mounting plate 2 is fixedly mounted with a storage tank 18. The storage tank 18 is connected to the inlet of the delivery pump 17 by a hose. The outlet of the delivery pump 17 is connected to the spraying rod 6 by a hose.

[0028] As a preferred option, an interface 12 is provided on one side of the outer wall of the cleaning cylinder 7. A connecting pipe 11 is provided between the interface 12 and the ring 9. The interface 12 is used to connect to an external water source and deliver the external water source to the nozzle 10.

[0029] As a preferred embodiment, further, the cleaning cylinder 7 is internally rotatably connected to a circular disc 24, which is located at the bottom of the slide groove 20. Four arc-shaped holes 25 are equidistantly spaced at the top of the circular disc 24. Inner sliders 26 are slidably connected within the arc-shaped holes 25, corresponding one-to-one with sliders 21. The inner sliders 26 and 21 are fixedly connected. Rotation of the circular disc 24 drives the arc-shaped holes 25 to rotate, compressing the inner sliders 26 and causing the four inner sliders 26 to move synchronously towards or away from the center. A slot 27 is formed on the outer wall of the cleaning cylinder 7. The slot 27 is an arc-shaped groove communicating with the circular disc 24. An extension rod 28 is slidably connected within the slot 27 and fixedly connected to the circular disc 24. One end of the extension rod 28, away from the circular disc 24, extends out of the slot 27. Magnetic block 29 and magnetic block 30 are installed at both ends of slot 27, and magnetic block 31 and magnetic block 42 are installed on the inner walls of both sides of slot 27, respectively. Magnetic block 29 and magnetic block 31 are compatible, and magnetic block 20 and magnetic block 42 are compatible. When the extension rod 28 moves to fit against the inner wall of the left side of slot 27, magnetic block 29 and magnetic block 31 attract each other, fixing the position of extension rod 28. When the extension rod 28 moves to fit against the inner wall of the right side of slot 27, magnetic block 20 and magnetic block 42 attract each other, fixing the position of extension rod 28. When the extension rod 28 moves to the left side of slot 27, the slider 21 is located in the groove 20 at the maximum extent. When the extension rod 28 moves to the right side of slot 27, the slider 21 is located in the groove 20 at the minimum extent. At this time, the brush 23 fits the outer wall of the spray rod 6 most tightly.

[0030] The spray bar, nozzle, delivery pump, and storage tank in this case are existing technologies. The spray bar has the same structure and connection method as those in the cited documents. Any spray bar, nozzle, delivery pump, and storage tank that meets the requirements of this case is acceptable and is not limited to a single model.

[0031] Working principle: The electrical components mentioned in this application are all connected to an external power supply and control switch during use. After the utility model is installed, first check the installation, fixation and safety protection of the utility model, and then it can be used. When using, the user pushes the device to the injection point where the pre-drilled hole is located, so that the through hole 13 is aligned with the hole. The user turns the knob 16, so that the knob 16 drives the screw 4 to rotate. The screw 4 drives the lifting plate 5 to move downward on the surface of the slide rod 3, so that the spray rod 6 passes through the cleaning cylinder 7 and the through hole 13, and then enters the groundwater. The delivery pump 17 is started to transport the liquid medicine in the storage tank 18 to the spray rod 6, and then transports it into the groundwater through the spray rod 6 for repair.

[0032] After the repair is completed, the user connects the external water source to interface 12, and then starts the nozzle 10 to spray water onto the outer wall of the spray rod 6. The user slides the extension rod 28, moving it from one end of the slot 27 to the other, causing magnetic block 1 29 to disengage from magnetic block 3 31, and magnetic block 2 30 to adhere to magnetic block 4 32. The extension rod 28 drives the annular disk 24 to rotate, which in turn drives the arc-shaped hole 25 to rotate. The arc-shaped hole 25 drives the inner slider 26 to move, causing the inner slider 26 to move the sliding... Block 21 slides within the groove 20, and the slider 21 drives the arc plate 22 and brush 23 to move, so that the brush 23 is in close contact with the outer wall of the spray rod 6. Then the user turns the knob 16, causing the knob 16 to drive the screw 4 to rotate in the opposite direction. The screw 4 drives the lifting plate 5 to move upward, so that the spray rod 6 slowly detaches from the cleaning cylinder 7. During the process of the spray rod 6 detaching, the nozzle 10 first rinses the outer wall of the spray rod 6, and then the brush 23 further cleans the rinsed outer wall, so as to automatically complete the cleaning of the spray rod 6.
