DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1 to 3. In the embodiment of the utility model, a water supply and drainage pipeline sealing structure includes a first pipeline

1. A second pipeline 2 and a lower detection box 15. The lower detection box 15 is arranged below the first pipeline 1 and the second pipeline 2. An upper detection box 3 is arranged on the upper end of the lower detection box 15. An alarm 4 is fixedly connected to the upper left end of the lower detection box 15. A plurality of buckles 16 are evenly arranged on the front and back of the lower detection box 15. A plurality of hooks 17 are evenly arranged on the front and back of the upper detection box 3. The upper detection box 3 and the lower detection box 15 are detachably connected through the buckles 16 and the hooks 17. When in use, the connected first pipeline 1 and the second pipeline 2 are placed on the lower detection box 15, and then the upper detection box 3 is connected to the lower detection box 15 through the buckles 16, which can detect whether there is water leakage at the interface.

A fastening assembly is provided between the ends of the first pipe 1 and the second pipe 2 for connecting the first pipe 1 and the second pipe 2. The fastening assembly comprises a threaded column 11 and a nut 12. The threaded column 11 is fixedly connected to the first pipe 1, and the nut 12 is slidably connected to the second pipe 2. The nut 12 and the threaded column 11 are threadedly connected. When in use, the first pipe 1 and the second pipe 2 are aligned, and then the two pipes are threadedly connected through the threaded column 11 at the right end of the first pipe 1 and the nut 12 at the left end of the second pipe 2.

The first pipe 1 is provided with a sealing assembly for preventing water leakage at the connection between the first pipe 1 and the second pipe 2. The sealing assembly includes a sealing groove 13 and a sealing ring 14. The sealing groove 13 is arranged at the right end of the threaded column 11, and the sealing ring 14 is arranged in the sealing groove 13. When in use, when the two pipes are aligned and tightened, the sealing ring 14 in the sealing groove 13 is squeezed by the left end of the second pipe 2 and filled in the sealing groove 13, thereby playing a sealing role.

The lower detection box 15 is provided with a detection component for detecting whether there is water leakage at the connection between the first pipe 1 and the second pipe 2. The detection component includes a float 5, a positioning rod 6, a push plate 7, a switch 8, and a second baffle 10. The upper end of the second baffle 10 is fixedly connected to the right end of the first baffle 9, and the left end of the first baffle 9 is fixedly connected to the lower detection box 15. The switch 8 is fixedly connected to the left side of the lower surface of the first baffle 9. The positioning rod 6 penetrates the first baffle 9, and the positioning rod 6 is slidably connected to the first baffle 9. The float 5 is fixedly connected to the lower end of the positioning rod 6, and the push plate 7 is fixedly connected to the left side of the positioning rod 6. When in use, if water leakage occurs at the interface of the two pipes, water will flow into the lower detection box 15. When more and more water flows into the lower detection box 15, the float 5 will rise with the water level. When it rises to a certain position, the push plate 7 will press the switch 8, and then the alarm will sound an alarm to remind the inspector that there is a water leakage here and maintenance is required.

The working principle of the utility model is as follows: when in use, align the first pipe 1 and the second pipe 2, and then tighten the nut 12 onto the threaded column 11. As the nut 12 is tightened, the left end of the second pipe 2 squeezes the sealing ring 14 in the sealing groove 13 at the right end of the first pipe 1, so that the sealing ring 14 is filled in the sealing groove 13, which plays a role in preventing water leakage. The buckle 16 buckled on the hook 17 of the upper detection box 3 is opened, the upper detection box 3 is removed, and then the first pipe 1 and the second pipe 2 screwed together are placed in the lower detection box 15, and then the upper detection box 3 is buckled to the hook 17 through the buckle 16 on the lower detection box 15 to cover it. The lower part of the lower detection box 15 is provided with a floating ball 5. The first baffle plate 9 and the second baffle plate 10 restrict the float 5 and only allow the float 5 to move up and down. There is a positioning rod 6 on the float, which passes through the first baffle plate 9. There is a push plate 7 on the positioning rod 6. There is a switch at the left end of the lower surface of the first baffle plate 9. If water leaks at the connection between the first pipe 1 and the second pipe 2, water will leak into the lower detection box 15. As the water level increases, the float 5 also rises. When it rises to a certain height, the push plate 7 will push the switch 8. When the switch 8 is pressed, the alarm 4 will sound an alarm to remind the inspectors, so that the inspectors can quickly know where maintenance is needed to prevent problems. The utility model is fixed for installation, easy to maintain and inspect, has good sealing performance, and is easy to use.
