Detailed Description

The utility model will be described in detail below with reference to the drawings in connection with embodiments. It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other. For convenience of description, the words "upper", "lower", "left" and "right" are used hereinafter to denote only the directions corresponding to the upper, lower, left, and right directions of the drawings, and do not limit the structure.

As shown in fig. 1 and 2, the pipe switching device provided in this embodiment is disposed between two abutted pipes 1, and the two abutted pipes 1 are disposed at intervals to form an installation space 8. The pipeline switching device comprises an outer sleeve 2, a plugging plate 3, a cam 4, a rotating shaft 5, a waterproof motor 6, a telescopic piece 7 and a housing 9.

The outer sleeve 2 is sleeved between the two pipelines 1 and covers the installation space 8. The length of the outer sleeve 2 is greater than the horizontal spacing between the two pipes 1. The outer sleeve 2 has a wall thickness for mounting to a bearing 11 fitted to the shaft 5.

The rotating shaft 5 and the cam 4 are both positioned in the installation space 8, and two ends of the rotating shaft 5 are respectively arranged in the pipe wall of the outer sleeve 2 in a rotating way through bearings 11. One end of the rotating shaft 5 extends out of the outer sleeve 2 and is connected with the waterproof motor 6. The waterproof motor 6 is required to be waterproof in terms of selection. And a cover shell 9 is sleeved outside the waterproof motor 6, the cover shell 9 is arranged on the pipe wall of the outer sleeve 2 through screws, and waterproof glue is smeared at each joint.
