At the same time, it is recovered through the output end of the electric push rod 11 on the second deflection rod 10, and the second deflection rod 10 slides on the reinforced slide frame 2 through the slide groove 9, so that the first deflection rod 3, the second deflection rod 10, the support plate 5 and the anemometer body 8 can be stored in the middle of the reinforced slide frame 2, and then recovered through the output end of the electric push rod 11 in the protection box 1, so that the reinforced slide frame 2 can be stored in the protection box 1, so as to avoid it from being damaged by external forces and improve the protection performance. The specific structure of the component is arranged as follows;

[0024] The support assembly includes a reinforced sliding frame 2 disposed in the protective box 1, and one end of the reinforced sliding frame 2 is hingedly connected to a first deflection rod 3 with an adjustable angle;

[0025] One end of the first deflection rod 3 is installed with a bearing seat 4 through bolts, and the bearing seat 4 is rotatably connected to a support plate 5, on which a rotating shaft 6 is inserted, and the outer side of the rotating shaft 6 is threadedly connected to a plurality of reinforcing rods 7, and one end of each reinforcing rod 7 is threadedly connected to an anemometer body 8, and slide grooves 9 are provided on both sides of the inner wall of the reinforced slide frame 2, and a second deflection rod 10 with an adjustable angle is provided in the middle of the reinforced slide frame 2, and both sides of the bottom of the second deflection rod 10 extend into the corresponding slide grooves 9, and the second deflection rod 10 is slidably connected to the slide grooves 9.
