The fixing section 3 includes a connecting sleeve 31 and a drilling head 32 . The connecting sleeve 31 is provided with a threaded hole 311 matching the screw rod 221 . The drilling head 32 is connected to the lower end of the connecting sleeve 31 .

[0039] The support section of the wind measuring device of the present invention is provided with an opening and closing shell, a lifting ring that can move up and down, and supporting legs that can be deployed and retracted, which can provide stable support for the device during wind measuring operations, and the opening and closing shell and the supporting legs can be retracted after the measurement is completed, which can save space and is convenient to carry; the drilling head of the fixed section is knocked into the ground during the measuring operation, and cooperates with the deployed opening and closing shell and supporting legs to ensure the stability and accuracy of the measurement.

[0040] According to an embodiment of the present invention, the measuring assembly 12 includes a universal ball end 121 movably connected to the supporting portion 11 and a wind cup 122 fixedly connected to the universal ball end 121. By arranging the universal ball end in the measuring section, the wind cup is tilted at a certain angle relative to the horizontal plane under the action of wind force, and the wind direction can be measured according to the direction generated by the tilt angle, and the wind speed under a specific wind direction can be evaluated according to the rotation speed of the wind cup, so that the wind direction and wind speed can be measured simultaneously through the same measuring assembly, making the structure of the device more compact and simple.
