Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1 to 4, a pipeline anemoscope includes a frame 1, a slip yoke 7 and yoke arms 8 symmetrically disposed at two ends of the slip yoke 7, a speed measuring fan 3 is mounted on the frame 1 through a mounting block 4, a lead screw 2 is connected to the middle of the frame 1 through a thread, one end of the lead screw 2 is rotatably connected to the middle of the slip yoke 7, a limiting groove 82 is disposed on the yoke arm 8, the end of the slip yoke 7 slides in the limiting groove 82, one end of the yoke arm 8 is hinged to the frame 1, the other end is hinged to a presser foot 9, a central processor and a signal generator 5 are disposed on the mounting block 4, and an antenna 6 is disposed on the central processor and the signal generator 5.

In this embodiment, two ends of the presser foot-1 9 are rotatably connected with the presser foot-II 10, and the presser foot-9 is connected with the presser foot-II 10 through the torsion spring 11, in the process of opening the yoke 8, the presser foot-II 10 contacts with the inner wall of the pipeline firstly, and then the presser foot-II 10 rotates with the presser foot-I9, so that the curved surface of the inner wall of the pipeline can be adapted, the contact area with the inner wall of the pipeline is increased, and the installation stability is improved.

In this embodiment, the bottom surfaces of the first presser foot 9 and the second presser foot 10 are both provided with rubber pads 13, and the rubber pads 13 can increase the friction force with the inner wall of the pipeline, thereby further improving the installation stability of the device.
