[0003] Before the installation and use of the drain pipe or during regular inspection, airtightness detection will be carried out to check whether there are leak points. Generally, the leak point detection device uses pressure detection. During the detection, it is necessary to block the drainage outlet. Gaps are likely to appear at the blocking interface, resulting in leakage of the detection gas. It is difficult for the detection air pressure inside the drainage pipe to reach the detection standard, which affects the detection result.

DETAILED DESCRIPTION
[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.
[0019] Reference Figures 1-3 As shown, a drainage pipe leakage detection device includes a water pipe main body 1, a sealing plate 2 is fixedly connected to the left side of the water pipe main body 1, an air intake pipe 3 is fixedly connected to the center position of the left end of the sealing plate 2, a detection ring 4 is slidably connected to the surface of the water pipe main body 1, and handles 5 are fixedly connected to the front and rear sides of the detection ring 4 to facilitate sliding the detection ring 4, a connecting pipe 6 is fixedly connected to the upper side of the detection ring 4, a pressure gauge 7 is fixedly installed on the upper end of the connecting pipe 6, a detection cavity 8 is opened inside the detection ring 4, and the lower end of the connecting pipe 6 passes through the upper side of the detection ring 4 and is connected to the interior of the detection cavity 8, which can effectively detect the location of the leakage point.
[0020] The right end of the water pipe body 1 is fixedly connected with a connecting flange 9, and the right end of the inner side of the water pipe body 1 is slidably connected with a sealing tube 10. The material of the sealing tube 10 is nitrile rubber, which has certain elasticity and good sealing performance. The front and rear ends of the right side of the water pipe body 1 are provided with a card slot 11. The front and rear sides of the right end of the sealing tube 10 are fixedly connected with a card block 12. The card block 12 is connected to the inner side of the card slot 11, which can effectively limit the sealing tube 10 and prevent the sealing tube 10 from rotating and sliding when installing the sealing thread rod 13. The internal thread of the sealing tube 10 is connected with the sealing thread rod 13. Rod 13, the right side of the blocking threaded rod 13 is fixedly connected to a connecting plate 14, and a fastening knob 15 is fixedly connected to the right center position of the connecting plate 14, which is convenient for installing the blocking threaded rod 13. A plurality of first connecting holes 16 are penetrated at the right peripheral position of the connecting plate 14, and a plurality of second connecting holes 17 are penetrated on the right side of the connecting flange 9. The interior of the first connecting hole 16 is slidably connected with a fastening bolt 18, and the left end of the fastening bolt 18 penetrates the interior of the second connecting hole 17 and is threadedly connected with a fastening nut 19, which effectively fixes the blocking threaded rod 13 and the connecting plate 14.
[0021] Working principle: Place the sealing tube 10 into the right end of the water pipe body 1, and at the same time place the card block 12 into the card slot 11, and then install the sealing threaded rod 13 into the sealing tube 10 by turning the tightening knob 15. The sealing tube 10 is squeezed and fits tightly against the inner wall of the water pipe body 1 to achieve the purpose of sealing. Finally, fix the connecting plate 14 by tightening the bolt 18 and the tightening nut 19. After the sealing threaded rod 13 is installed and fixed, input the detection gas through the air inlet pipe 3. When the air pressure inside the water pipe body 1 reaches the detection pressure, if there is no leak, the air pressure remains stable. If a leak occurs, the air pressure will continue to decrease. At this time, the detection gas is replenished, and the detection ring 4 is slid by the handle 5. When it slides to the leak position, the detection gas will enter the detection chamber 8. The gas pressure inside the detection chamber 8 will suddenly increase. The pressure gauge 7 can intuitively display the test results and mark the leak position. After the test is completed, it can be repaired.
