Description

Technical Field

[0001] The utility model relates to the field of closed water test, in particular to a sewage pipe closed water test plugging device. Background Art

[0002] A plug, also known as a pipe cap, cap, or blind plug, is a pipe fitting that is installed over the external threads of a pipe end to seal it. It serves the same function as a pipe plug and can be screwed directly onto the pipe without the need for other fittings. Plugs include convex plugs, conical shells, reducers, flat caps, and constriction designs.

[0003] Chinese patent number CN202323503648.4 discloses a sewage pipe closed water test plug device, including a mounting plate and a fixing assembly; the mounting plate: an elastic plate is provided in a circular array on the outer edge of its right side surface, a rubber sheath is covered between the left side surface of the mounting plate and the outer arc surface of the elastic plate, a rubber convex ring is provided on the outer edge of the right end of the rubber sheath, the inner arc surface of the rubber convex ring is fixedly connected to the outer surface of the right end of the elastic plate, the middle part of the mounting plate is rotatably connected to the adjustment assembly, and the adjustment assembly is slidably connected to the inner wall surface of the right end of the elastic plate.

[0004] From the above, it can be seen that the inner arc surface of the rubber convex ring located between the two adjacent elastic plates contacts the outer arc surface of the left end of the frustum disk, and the outer arc surface of the rubber convex ring located between the two adjacent elastic plates forms a good sealing effect with the inner wall of the sewage pipe. The installation is simple and convenient, which improves work efficiency. However, this case still has the following shortcomings: when conducting the plug water sealing test, the existing device is usually installed by personnel during monitoring, which requires personnel to constantly rotate the plug during work to connect the plug to the pipe. It has certain limitations in use and increases the labor intensity of the testers.

[0005] Therefore, in order to solve the above problems, a sewage pipe water-tightness test plugging device is proposed. Utility Model Content

[0024] During operation, the servo motor 22 provides power, and drives the movable arm 24 to perform corresponding rotational activities, so that the linkage rod 25 hinged on the movable arm 24 generates linkage with the linkage arm 26, which is conducive to providing power to ensure the operation of the linkage arm 26.

[0025] Furthermore, the main body 1 is mounted with a fixing frame 11, a pressure tester 13 is fixedly mounted on one side of the fixing frame 11, and a housing 21 is fixedly mounted on one side of the fixing frame 11;
