[0043] Working principle: When in use, when leakage occurs at a certain position of the pipe connection, the detection component can detect the specific leakage, and then the storage barrel 3 and the discharge pipe 4 are brought to the leakage through the temporary repair component. During the movement of the storage barrel 3, the stirring component can stir the repair material in the storage barrel 3 to prevent the repair material from changing due to long-term placement. The temporary repair component can squeeze the repair material stored in the storage barrel 3 to the leakage. When the temporary repair component moves to the leakage, it can also drive the reminder component through the detection component, so that the reminder component sends a signal. When the inspection personnel pass by and see the reminder component, they can know that there is leakage at the pipe connection;

[0044] When it is necessary to make the storage barrel 3 and the discharge pipe 4 reach the leakage, the first motor 7 is started, and the first motor 7 drives the first circular gear 8 to rotate, and the first circular gear 8 moves on the ring gear 9, thereby driving the storage barrel 3 and the discharge pipe 4 to move along the ring gear 9, so that the storage barrel 3 and the discharge pipe 4 reach the corresponding position of the leakage, and then the electric push rod 6 is started, and the electric push rod 6 drives the storage barrel 3 and the discharge pipe 4 to reach the leakage. At this time, the discharge pipe 4 is facing one end of the leakage. By rotating the stirring shaft 10, the stirring shaft 10 can squeeze the repair material in the storage barrel 3 from the discharge pipe 4 through the spiral blade 11, and the elastic sealing sheet is squeezed open, and the repair material is squeezed to one end of the leakage. The first circular gear 8 is driven by the first motor 7 to move on the ring gear 9, so that the extruded repair material can form a path to cover the leakage.

[0045] When the discharge pipe 4 extrude the repair material, the scraper 16 moves along with the discharge pipe 4, and the discharge pipe 4 extrude a repair material path. Under the action of the first spring 15, the scraper 16 can smear and scrape the repair material on the pipe connection.

[0046] During the movement of the storage barrel 3 along the annular gear 9, since the second circular gear 21 is always meshed with the annular gear plate 22, during the movement of the storage barrel 3, the annular gear plate 22 will drive the second circular gear 21 to rotate, and the second circular gear 21 drives the rotating shaft 18 to rotate, and the rotating shaft 18 drives the stirring shaft 10 to rotate through the two bevel gears 19, and the stirring shaft 10 drives the stirring rod 20 to rotate, and the stirring rod 20 can stir the repair material to prevent the repair material from changing after being placed for a long time, and the stirring shaft 10 can also drive the spiral blade 11 to rotate, so that the spiral blade 11 conveys the repair material inward away from the discharge pipe 4 to prevent the spiral blade 11 from conveying the repair material out of the discharge pipe 4, when it is necessary to extrude the repair material, start the second motor 23, the second motor 23 drives the third circular gear 24 to rotate, and the third circular gear 24 drives the annular gear plate 22 to rotate, and the annular gear plate 22 can drive the stirring shaft 10 and the spiral blade 11 to rotate, so that the spiral blade 11 conveys the repair material in the direction of the discharge pipe 4, and the repair material is smoothly extruded;

[0047] When a certain position of the pipe connection is damaged, the liquid in the pipe will be sprayed out from the damaged position and sprayed onto the corresponding detection plate 27. The detection plate 27 is subjected to pressure by the liquid spray, and the detection plate 27 moves toward the fixed cylinder 25. The detection plate 27 drives the moving column 26 to be gradually inserted into the fixed cylinder 25. The second spring 28 is compressed, and one end of the moving column 26 contacts the sensing block 30. Then, the specific leakage position of the pipe connection can be known, and the storage barrel 3 and the discharge pipe 4 are driven by the temporary repair component to temporarily repair the leakage at that place;

[0048] When the detection plate 27 detects a specific leakage, the storage barrel 3 and the discharge pipe 4 will reach the leakage. When the electric push rod 6 drives the storage barrel 3 and the discharge pipe 4 to the leakage, the discharge pipe 4 drives the arc plate 33 to move through the fixed rod 32, so that the arc plate 33 contacts the outer wall of the moving column 26 inserted into the fixed cylinder 25. The arc plate 33 can continue to push the moving column 26, so that the fixed cylinder 25 as a whole slides in the limiting groove of the limiting block 34, and the third spring 35 is compressed. Due to the friction between the arc plate 33 and the moving column 26, after the detection plate 27 leaves the leakage, the moving column 26 and the detection plate 27 will not reset, and the second spring 28 remains compressed.

[0049] When water at the leakage site is sprayed onto the detection plate 27, the movable column 26 moves into the fixed cylinder 25, and the movable column 26 can push the air in the fixed cylinder 25 into the rubber membrane 36 through the through hole 37, so that the rubber membrane 36 expands. When the fixed cylinder 25 and the movable column 26 are pushed away from the leakage site, the connecting pipe 39 is directly opposite to the vertical pipe 40, so that the connecting pipe 39 and the vertical pipe 40 are connected, and the air in the rubber membrane 36 enters the vertical pipe 40. The air can push the piston block 42 in the vertical pipe 40 to move, and the fourth spring 41 is compressed. The mixed liquid in the vertical pipe 40 will be pressed into the transparent tube 43. When the inspection personnel see the mixed liquid in the transparent tube 43, , the inspection personnel will know that there is leakage at the connection of the pipeline, and according to the position of the transparent tube 43, the specific leakage position can be determined, and the first shell 1 and the second shell 2 can be opened for maintenance and repair. The larger the leakage is, the greater the force of the sprayed liquid is, the more distance the detection plate 27 and the moving column 26 move, the more air can be pressed into the rubber membrane 36 by the moving column 26, the more the rubber membrane 36 expands, the more air the rubber membrane 36 enters the vertical pipe 40, the more mixed liquid of the piston block 42 can be pressed into the transparent tube 43 by the air, the higher the liquid level in the transparent tube 43 is, the inspection personnel can know the degree of leakage according to the liquid level height of the transparent tube 43;

[0050] When the connecting tube 39 reaches the vertical tube 40, it is necessary to connect the connecting tube 39 with the vertical tube 40, start the two electromagnetic plates 50, and the two electromagnetic plates 50 repel each other. One of the electromagnetic plates 50 drives the second circular plate 49 and the connecting tube 51 to move, and the fifth spring 48 is stretched. The connecting tube 51 drives the top block 54 to move, so that the connecting tube 51 is sleeved on the outer wall of the connecting tube 39. The top block 54 can push the blocking ball 46 off the fixing seat 44, and the connecting rope 45 is stretched. The air in the rubber membrane 36 will enter the vertical tube 40 from the connecting tube 39 and the connecting tube 51.
