The connecting buffer mechanism is arranged on the adjacent side of the two drainage pipe bodies.

[0004] When the above technical solution is adopted, when the water flow contacts the buffer ring, the buffer ring will be squeezed to cause the buffer ring to deform, thereby resisting the water flow, buffering and slowing down the water flow, and reducing the damage to the two drainage pipe bodies caused by the water flow.

The bolts 6 cooperate with the first flange 4 and the second flange 5 to fix the position of the butt joint 2 on the connecting pipe 1 and ensure the firmness of the connection between the butt joint 2 and the connecting pipe 1.

[0025] Rubber airbags 303 are provided inside the two sealing grooves 302, and the inner walls of the two rubber airbags 303 are in contact with the outer surfaces of the two docking pipes 2 respectively.

The water outlet ends of the plurality of first one-way valves 305 all pass through the interior of the rubber airbags 303. Two first sealing rings 7 are fixedly connected to the inner wall of the connecting pipe 1, and the inner walls of the two first sealing rings 7 are in contact with the outer surfaces of the two docking pipes 2 respectively. The first sealing rings 7 can preliminarily increase the sealing between the connecting pipe 1 and the docking pipe 2, thereby ensuring the airtightness of the docking pipe 2 after docking through the connecting pipe 1.

[0026] The outer surfaces of the two rubber airbags 303 are fixedly connected to the pressure relief valve 306, the water outlet ends of the two pressure relief valves 306 pass through the connecting pipe 1 and are fixedly connected to the connecting pipe 307, the outer surfaces of the two connecting pipes 307 are fixedly connected to the second one-way valve 308, the water outlet ends of the two second one-way valves 308 pass through the connecting pipe 1 and the limit ring 301 in sequence and extend to the inside of the limit ring 301, the inner walls of the two collecting tanks 304 are fixedly connected to the second sealing ring 8, the inner walls of the two second sealing rings 8 are respectively in contact with the outer surfaces of the two docking pipes 2, the second sealing ring 8 can prevent water from leaking outward through the gap between the collecting tank 304 and the docking pipe 2, thereby ensuring the water collection effect of the collecting tank 304 and further improving the anti-leakage effect of the connecting pipe 1.

[0027] The interiors of the two connecting pipes 307 are rotatably connected to rotating rods 309, and the outer surfaces of the two rotating rods 309 are fixedly connected to spiral racks 310.

[0029] The working principle of the present invention is as follows: when in use, first insert the butt joint pipe 2 to be butted into the connecting pipe 1 until the butt joint pipe 2 contacts the limit ring 301, and then use the bolts 6 to cooperate with the first flange 4 and the second flange 5 to fix the position of the butt joint pipe 2 on the connecting pipe 1, and then the butt joint work of the two butt joint pipes 2 can be completed. When the first sealing ring 7 fails due to corrosion or other reasons after long-term use, so that the gap between the butt joint pipe 2 and the connecting pipe 1 leaks, the leaked water will first enter the collecting tank 304 for temporary storage. When the water pressure inside the collecting tank 304 is relatively high, it will enter the rubber airbag 303 through the first one-way valve 305. As the water enters the rubber airbag 303, it will gradually expand, and then it can cooperate with the sealing groove 302 to further block the gap between the butt joint pipe 2 and the connecting pipe 1, so that the water will not continue to leak to the outside. When the internal pressure of the rubber airbag 303 is greater than the internal pressure of the pressure relief valve 306, When the pressure is constant, the water inside the rubber airbag 303 can enter the connecting pipe 307 through the pressure relief valve 306, and finally flow back into the connecting pipe 1 through the second one-way valve 308, so that it can absorb and balance the leakage pressure of the water while further preventing the water from leaking out. When the water flows through the connecting pipe 307, the spiral shape of the spiral frame 310 cooperates with the limit of the stable seat 9 to push the rotating rod 309 to rotate, and then drive the internal rotor of the small generator 311 to rotate, so that the small generator 311 generates the electricity required for the alarm light 313 and the buzzer 314 to work, so that the alarm light 313 emits a warning light and the buzzer 314 emits an alarm sound to remind the inspection personnel of the leakage here, so that the urban water supply and drainage pipe connection device has a good anti-leakage function, and at the same time can timely issue a leakage alarm to the inspection personnel, thereby increasing the safety of the urban water supply and drainage pipe connection device.
