[0023] Please refer to the attached Figure 3 -Attached Fig. 9 In a preferred embodiment, the sealing assembly includes: a sealing plug 15, the sealing plug 15 is horizontally arranged below the horizontal side of the L-shaped frame 3, the sealing plug 15 is used to block the top of the detection tube 9, and the end of the sealing plug 15 is conical, two electric telescopic rods 5 are installed on the top of the horizontal side of the L-shaped frame 3, and the output ends of the two electric telescopic rods 5 are fixedly installed on the top of the sealing plug 15, and a dual-function air pump 4 is installed on the top of the horizontal side of the L-shaped frame 3. One end of the dual-function air pump 4 passes through the horizontal side of the L-shaped frame 3. A through circular groove is opened on the top of the sealing plug 15, and a connecting pipe 16 connected to the circular groove is vertically fixedly installed on the top of the sealing plug 15, and the surface of the connecting pipe 16 is slidably installed in the corresponding end of the dual-function air pump 4, a tray 31 is fixedly installed on the top of the fixed plate 2, and a rubber pad 35 is fixedly installed on the top of the tray 31, and the rubber pad 35 and the tray 31 are both in contact with the end of the arc-shaped support plate 6; Furthermore, if the pipeline is not located at the center of the detection cylinder 9, the downwardly moving sealing plug 15 will move the pipeline to the center of the detection cylinder 9, and finally the downwardly moving sealing plug 15 and the rubber pad 35 can cooperate to seal the pipeline and the detection cylinder 9 respectively.

[0024] The working principle of the present invention is as follows: firstly, the building pipe to be inspected is placed inside the corresponding inspection tube 9, and the end of the building pipe to be inspected will contact the arc-shaped support plate 6; Then, the driving motor 17 is started to drive the turntable 8 to rotate 120 degrees, the turntable 8 rotates to drive the spring rod 10 to rotate, the spring rod 10 rotates to drive the U-shaped frame 14 to rotate, the U-shaped frame 14 rotates to drive the connecting parts thereon to rotate 120 degrees together, and the detection cylinder 9 rotates to drive the building pipeline inside it to rotate 120 degrees. It should be noted that the detection cylinder 9 and the pipeline both slide between the arc-shaped support plate 6; When the detection tube 9 and the pipeline are located at the top of the rubber pad 35, the electric telescopic rod 5 is started, and the electric telescopic rod 5 drives the sealing plug 15 to move downward. Since the end of the sealing plug 15 is conical, the end of the sealing plug 15 will first enter the inside of the pipeline. If the pipeline is not located at the center of the detection tube 9, the sealing plug 15 moving downward will move the pipeline to the center of the detection tube 9. Finally, the sealing plug 15 moving downward and the rubber pad 35 can cooperate to seal the pipeline and the detection tube 9 respectively. Then, a certain amount of gas is inflated into the pipeline through the dual-function air pump 4. If the pipeline is qualified, the impeller 32 will not rotate and the pipeline will not disintegrate. If the pipeline crack detection fails, the pipeline will leak into the detection tube 9, and the gas inside the detection tube 9 will be discharged to the outside through the outlet pipe 19. The gas inside the outlet pipe 19 will drive the impeller 32 to rotate when it flows, and the impeller 32 will rotate. The rotation of the rotating rod 20 drives the sleeve disc 21 to rotate. The rotation of the sleeve disc 21 drives the first connecting rod 22, the counterweight block 24 and the second connecting rod 23 to rotate. Due to the action of centrifugal force, the counterweight block 24 will move horizontally. The horizontal movement of the counterweight block 24 will cause the second connecting rod 23 to pull the sliding plate 26 downward and make the first spring 28 generate tension. The sliding plate 26 moves downward to drive the movable rod 27 to move. The movement of the movable rod 27 drives the sealing rod 30 to move toward the detection tube 9. The movement of the sealing rod 30 drives the paintbrush 34 to move inside the detection tube 9, so that the paintbrush 34 marks on the pipeline, indicating that the pipeline is damaged. If the pipeline disassembly test fails, a loud sound will be emitted from the inside of the detection tube 9, and then the gas inside the pipeline can be partially extracted through the dual-function air pump 4 to avoid high pressure inside the detection tube 9 when the sealing plug 15 and the detection tube 9 are separated; Then the driving motor 17 is operated to drive the U-shaped frame 14 and its connecting parts to rotate 120 degrees. At this time, the first gear 13 will mesh with the teeth on the toothed disc 11 and make the first gear 13 rotate forwardly. The forward rotation of the first gear 13 drives the second pulley 40, the belt 38, the first pulley 39 and the second bevel gear 37 to rotate. The rotation of the second bevel gear 37 drives the first bevel gear 36 to rotate. The rotation of the first bevel gear 36 drives the detection cylinder 9 to rotate. The rotation of the detection cylinder 9 drives the detected pipeline to rotate, so that the detected pipeline can slide into the detection cylinder 9 and fall on the blanking plate 7 to be collected. It should be noted that the disintegrated pipeline fragments will fall onto the fixed plate 2 when the detection cylinder 9 and the rubber pad 35 are separated. Finally, the driving motor 17 is started to drive the U-shaped frame 14 and the components thereon to rotate 120 degrees, and the first gear 13 will mesh with the teeth on the gear ring 12. At this time, the first gear 13 will rotate in the opposite direction. In summary, it can be seen that the detection cylinder 9 will be reset. Finally, the detection cylinder 9 will return to the starting position after being reset. It should be noted that there is a certain friction between the first bevel gear 36 and the U-shaped frame 14, which ensures the stability between the detection cylinder 9 and the U-shaped frame 14; In summary, the building pipelines can be continuously inspected by reciprocating in sequence, and the inspection is convenient, fast and accurate, thereby improving the use effect of the equipment.

[0025] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
