[0018] The installation assembly includes a connector 2 welded and fixed on the outer wall of the pipeline of the connecting pipe 1, and a positioning plate 3 and an elastic limiter 4 welded and fixed on the back side of the pipeline wind speed measuring device 5. The positioning plate 3 is symmetrically arranged on the upper and lower sides of the detection rod 5A of the pipeline wind speed measuring device 5. The elastic limiter 4 is symmetrically arranged on the left and right sides of the detection rod 5A, including a pair of horizontally arranged limit supports and a limit card plate 4A connected to the inner end of the limit support, the outer end of the limit support is fixedly connected to the back side of the pipeline wind speed measuring device 5, and the inner end is tilted. The elastic limiter 4 is formed in one piece with elastic metal material and has high reliability. The center of the connector 2 is provided with a detection rod jack (the aperture is slightly larger than the diameter of the detection rod 5A, so that it can be easily plugged in and out even if there are attachments on the upper part), the upper and lower sides are provided with slots that cooperate with the positioning plate 3, and the left and right sides are provided with card slots that cooperate with the limit card plate 4A. In order to further improve the connection reliability, the edge of the positioning plate 3 and the slot plug-in side is provided with a limit edge. The thickness of the limiting edge is greater than the thickness of the main body of the positioning plate 3, so as to play a limiting role. The utility model does not limit the shape of the limiting edge, for example, the cross section can be arc-shaped, wedge-shaped, etc. Through the installation component, the pipeline wind speed measuring device 5 can be conveniently installed on the connecting pipe 1. Specifically, during installation, the detection rod 5A is first inserted into the connecting pipe 1 through the detection rod jack of the connecting head 1, and then moved inward, so that the positioning plate 3 is inserted into the slot of the connecting head 1, and the limiting card plate 4A is inserted into the card slot of the connecting head 1, so that the wind speed measuring device 1 is conveniently fixed.

[0019] The cleaning assembly includes a connecting frame, the inner side of which is fixedly connected to the outer wall of the connecting pipe 1. Specifically, the connecting frame includes two horizontally arranged triangular connecting ribs 6, the inner side edges of the connecting ribs 6 are arc-shaped and welded to the outer wall of the pipe, the front sides of the two connecting ribs 6 are connected with mounting plates 7, the inner corners of the connecting ribs 6 are vertically connected with vertical connecting ribs 8, the length of the vertical connecting ribs 8 is greater than the spacing between the connecting ribs 6 (in this embodiment, the vertical connecting ribs 8 are the same length as the connecting pipe 1), the structure is simple, and the connection is reliable.

[0020] A T-shaped positioning block 9 is fixed on the back side of the mounting plate 7, and a cleaning block 10 made of sponge material is installed on the positioning block 9.
