[0023] The following further illustrates the above and other technical features and advantages of the present invention in conjunction with the accompanying drawings and embodiments. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive. Example

[0024] like Figures 1-4 As shown, the utility model provides a pipeline emergency plugging device, including an outer fixing ring 1, a limiting bracket 2 is provided on one side of the outer fixing ring 1, a slide groove 3 is provided on both sides of the limiting bracket 2, a support shaft 4 is sleeved inside the slide groove 3, a closing plate 5 is installed on one side of the support shaft 4, the closing plate 5 is nested in the outer fixing ring 1, and the closing plate 5 plays a role in sealing the outer fixing ring 1, an auxiliary limiting device is provided in the middle of the slide groove 3, the auxiliary limiting device conflicts with the closing plate 5, and limits the closing plate 5 from deflecting through the support shaft 4;

[0025] The closing plate 5 is pushed by the auxiliary limiting device into the interior of the outer fixing ring 1 and maintains a stable embedded state, and the closing plate 5 completes the sealing of the outer fixing ring 1.

[0026] The outer diameter of the closing plate 5 is consistent with the inner diameter of the outer fixing ring 1 . A sealing ring for sealing the connection is provided on the periphery of the end of the closing plate 5 . The closing plate 5 can maintain the sealing of the connection after entering the interior of the outer fixing ring 1 .

[0027] Both ends of the support shaft 4 are cylindrical, and the support shaft 4 is embedded in the slide groove 3 through the cylindrical part. The two ends of the support shaft 4 are in conflict with the inner wall of the limit bracket 2. When the closing plate 5 connected to the support shaft 4 is moved away from the inside of the outer fixing ring 1, the closing plate 5 can support the shaft 4 as the axis to rotate, forming an inclined setting state, thereby reducing the impact of the airflow or water flow in the closed pipe on the closing plate 5 and improving the service life of the structure.

[0028] A threaded hole is opened in the middle of the limit bracket 2, and a reinforcement sleeve 6 is connected to the outside of the threaded hole. The auxiliary limiting device is arranged in the reinforcement sleeve 6, and the auxiliary limiting device includes a transmission screw 7, a rotating wheel 8 and a push plate 9;

[0029] The transmission screw 7 is sleeved in the reinforcement sleeve 6 and is threadedly connected to the threaded hole. The rotary wheel 8 is installed at one end of the transmission screw 7, and the push plate 9 is installed at the other end of the transmission screw 7. The diameter of the push plate 9 is consistent with the width of the support shaft 4. The push plate 9 and the transmission screw 7 are rotatably connected. The push plate 9 is in contact with the surface of the support shaft 4. When the outer fixing ring 1 needs to be closed, the rotary wheel 8 is rotated to drive the transmission screw 7 to rotate. The transmission screw 7 moves laterally along the threaded hole through the threaded connection with the threaded hole, and the transmission screw 7 moves laterally. During the process, the push plate 9 is pushed so that the push plate 9 gradually conflicts with the support shaft 4. After the push plate 9 completely conflicts with the support shaft 4, the support shaft 4 remains in a vertical state, and the closing plate 5 connected to the support shaft 4 remains in a vertical state simultaneously. By continuously cooperating with the transmission screw 7 and the push plate 9, the closing plate 5 can be pushed to the inside of the outer fixing ring 1 to complete the closure. The surface of the push plate 9 is ground. The push plate 9 with the ground surface treatment can increase the friction between the push plate 9 and the support shaft 4, thereby reducing the rotational wear of the push plate 9 after contacting the support shaft 4.

[0030] The external thread of the outer fixing ring 1 is connected to the outer expansion ring 10, and the surface of the outer expansion ring 10 is provided with several groups of fixing hole plates 11 for fixing to the external environment. The outer expansion ring 10 is provided with several groups of different specifications. The inner diameters of the outer expansion rings 10 of different specifications are consistent with the outer diameter of the outer fixing ring 1. The outer diameters of several groups of outer expansion rings 10 increase one by one. When the diameter of the outer fixing ring 1 is smaller than the diameter of the pipe to be sealed, an outer expansion ring 10 of adapted specifications can be selected to be connected to the outer fixing ring 1. After the outer expansion ring 10 is connected, the outer fixing ring 1 can adapt to the diameter of large-sized pipes, thereby ensuring the device's sealing requirements for pipes of different specifications.

[0031] The above description is merely a preferred embodiment of the present invention and is intended to be illustrative rather than restrictive of the present invention. Those skilled in the art will appreciate that many changes, modifications, and even equivalents may be made to the present invention within the spirit and scope of the claims, and all of these changes will fall within the scope of protection of the present invention.
