[0024] The embodiment of the utility model provides a quick connection device for repairing municipal pipelines.

[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , including a pipeline structure, two connecting sleeves 1 are arranged on the outside of the pipeline structure, and a rubber pad 2 is fixedly connected to one side of the two connecting sleeves 1. The two connecting sleeves 1 are both provided with a movement groove 12, and an upper sealing plate 7 is arranged on the top of the inner cavity of the movement groove 12, and a top sealing box 3 is arranged on the outside of the upper sealing plate 7. A first telescopic pneumatic cylinder 6 is arranged inside the top sealing box 3, a lower sealing plate 8 is arranged at the bottom of the inner cavity of the movement groove 12, and a pressure sensor 11 is arranged at the bottom of the lower sealing plate 8, a bottom sealing box 4 is sleeved on the outside of the lower sealing plate 8, and a second telescopic pneumatic cylinder 9 is arranged inside the bottom sealing box 4.

[0026] When the utility model is in use: the pipeline structure includes a water diversion pipeline 18, an external threaded pipe 20 is threadedly connected inside the water diversion pipeline 18, and one end of the external threaded pipe 20 extends to the inside of a preparation pipeline 19 and is fixedly connected to the preparation pipeline 19. When the preparation pipeline 19 is damaged, the two connecting sleeves 1 are sleeved onto the outside of the water diversion pipeline 18, and a part of the connecting sleeve 1 and the rubber pad 2 are controlled to be arranged on the outside of the preparation pipeline 19.

[0027] A plurality of threaded holes 13 are provided on the outside of the two connecting sleeves 1. A fixing bolt 14 is aligned with one of the threaded holes 13. Figure 4 As shown, after the fixing bolt 14 is rotated and inserted into the threaded hole 13 opened in the connecting sleeve 1, the two connecting sleeves 1 are fixed together. At this time, the rubber pad 2 fixed to the connecting sleeve 1 is deformed and wrapped around the outside of the water diversion pipe 18, and the rubber pad 2 increases the sealing between the water diversion pipe 18 and the connecting sleeve 1. A battery 16 is fixedly connected to one side of the bottom sealing box 4, and the battery 16 stores electricity. After pressing the button 17 installed on one side of the battery 16, the first telescopic pneumatic cylinder 6 and the second telescopic pneumatic cylinder 9 electrically connected by the button 17 work, and the battery 16 provides power for the operation of the first telescopic pneumatic cylinder 6 and the second telescopic pneumatic cylinder 9. It is only necessary to use a wire with a certain reserved margin to connect the battery 16, the first telescopic pneumatic cylinder 6 and the second telescopic pneumatic cylinder 9, so that the first telescopic pneumatic cylinder 6, the second telescopic pneumatic cylinder 9 and the battery 16 can be electrically connected together.

[0028] When the two connecting sleeves 1 are sleeved on the outside of the water diversion pipe 18, the connecting sleeve 1 installed on the top sealing box 3 is controlled to be located at the top. At this time, the first telescopic pneumatic cylinder 6 fixed inside the top sealing box 3 works to push the upper sealing plate 7 downward. At this time, the second telescopic pneumatic cylinder 9 is located at the bottom of the lower sealing plate 8, and the working second telescopic pneumatic cylinder 9 pushes the lower sealing plate 8 upward, and the upward lower sealing plate 8 and the downward upper sealing plate 7 are sleeved on the outside of the preparation pipe 19 at the same time. A pressure sensor 11 is arranged on the top of the second telescopic pneumatic cylinder 9 fixed inside the bottom sealing box 4, that is, the pressure sensor 11 is arranged on the top of the extension end of the second telescopic pneumatic cylinder 9 and contacts the second telescopic pneumatic cylinder 9, so the second telescopic pneumatic cylinder 9 extends and contacts the pressure sensor 11 to push the lower sealing plate 8 upward, and when the movement of the lower sealing plate 8 is blocked by the preparation pipe 19, the pressure value detected by the pressure sensor 11 increases.

[0029] When the pressure value detected by the pressure sensor 11 reaches a preset value, the first telescopic pneumatic cylinder 6 and the second telescopic pneumatic cylinder 9 electrically connected to the pressure sensor 11 stop working. At this time, the upper sealing plate 7 and the lower sealing plate 8 are sleeved onto the outside of the preparation pipe 19, and the upper sealing plate 7, the lower sealing plate 8, the top sealing box 3 and the bottom sealing box 4 seal the outside of the preparation pipe 19 and the connecting sleeve 1. In addition, the friction between the upper sealing plate 7 and the lower sealing plate 8 and the preparation pipe 19 is relatively small. The upwardly moved preparation pipe 19 can rotate to drive the external threaded pipe 20 to leave the inside of the water diversion pipe 18. After the preparation pipe 19 is out of contact with the upper sealing plate 7 and the lower sealing plate 8, the pressure sensor 11 detects that the pressure value is reduced. At this time, the first telescopic pneumatic cylinder 6 and the second telescopic pneumatic cylinder 9 work again, the upper sealing plate 7 moves down, and the lower sealing plate 8 moves up. After the recessed parts of the upper sealing plate 7 and the lower sealing plate 8 miss each other, the upper sealing plate 7 and the lower sealing plate 8 are moved up. Plate 7 and lower sealing plate 8 form a blocking plate, and upper sealing plate 7, lower sealing plate 8, top sealing box 3 and bottom sealing box 4 seal the two connecting sleeves 1. During this process, the preparation pipe 19 does not leave between the two connecting sleeves 1, and most of the water inside the upward water diversion pipe 18 is guided by the preparation pipe 19, avoiding the situation where water inside the water diversion pipe 18 sprays out after the preparation pipe 19 is disassembled, and quickly seals one end of the water diversion pipe 18, providing time for the staff to replace the preparation pipe 19, thereby reducing the waste of water resources.

[0030] Subsequently, the staff inserts the externally threaded tube 20 fixed at one end of the new preparation pipe 19 between the two connecting sleeves 1. When the externally threaded tube 20 is blocked by the lower sealing plate 8, the staff presses the button 17 for the second time to shrink the first telescopic pneumatic cylinder 6 and the second telescopic pneumatic cylinder 9 to restore the original state. The first telescopic pneumatic cylinder 6 drives the upper sealing plate 7 to reset, and the bottom of the lower sealing plate 8 loses the support of the second telescopic pneumatic cylinder 9 and falls. Subsequently, the preparation pipe 19 is rotated to move toward the water diversion pipe 18, so that the externally threaded tube 20 is rotated and inserted into the water diversion pipe 18, and the preparation pipe 19 and the water diversion pipe 18 are fixed together. In this process, the gap between the preparation pipe 19 and the two connecting sleeves 1 is small, and the water flow sprayed to the outside of the connecting sleeve 1 is small, which will not affect the staff. After the staff aligns the preparation pipe 19 with the water diversion pipe 18, the preparation pipe 19 moves toward the water diversion pipe 18 under the guidance of the two connecting sleeves 1. The water sprayed from the water diversion pipe 18 will not affect the installation of the preparation pipe 19, thereby increasing the speed of installation and fixation of the preparation pipe 19 and the water diversion pipe 18 and reducing the time investment.

[0031] A groove 10 is provided on the outer side of the lower sealing plate 8, and a pressure sensor 11 is arranged inside the groove 10 and fixedly connected to the lower sealing plate 8 to ensure the flatness of the bottom of the lower sealing plate 8 so that the lower sealing plate 8 can move downward stably under the influence of gravity.

[0032] An elastic member 15 is fixedly connected between the two connecting sleeves 1. The elastic member 15 that can be elastically deformed will not affect the connection sleeve 1 being installed on the outside of the water diversion pipe 18, and prevents the two connecting sleeves 1 from being completely separated. A handle 5 is fixedly connected to one side of the top sealing box 3 and the bottom sealing box 4. The top sealing box 3 and the bottom sealing box 4 are both fixedly connected to the adjacent connecting sleeves 1. The handle 5 provides a fulcrum for the staff to operate the connecting sleeve 1, thereby improving the convenience of operating the connecting sleeve 1.

[0033] If hot-melt material is needed to repair the external cracks of the prepared pipe 19, place the hot-melt material on the outside of the prepared pipe 19, then put the two connecting sleeves 1 on the outside of the prepared pipe 19, and control the positions of the top sealing box 3 and the bottom sealing box 4 so that the upper sealing plate 7 and the lower sealing plate 8 are aligned with the hot-melt material. Then, press the control button on one side of the battery 16 to make the first telescopic pneumatic cylinder 6 and the second telescopic pneumatic cylinder 9 work to push the upper sealing plate 7 and the lower sealing plate 8 toward the hot-melt material. At the same time, the working upper sealing plate 7 and the lower sealing plate 8 generate heat to make the hot-melt material stick to the prepared pipe 19. After rotating the two connecting sleeves 1, perform the above work again to complete the repair of the prepared pipe 19.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
