Embodiment Construction
[0045] like figure 1 As shown, it includes a traction module and a measurement module. The traction module includes a load-bearing drone 3 (traction device), a lock 4, a high-strength string 5 (traction rope), a cable tie 8 and an anchor frame 11. The amount The measuring module includes an Owen probe 6, a pressure measuring tube 7, an accelerometer 9, a scanning valve 10, an acquisition host 13 and a computer 14. The mobile anchoring frame 11 is set on the ground 12 in the wake area of the wind turbine 2, and the high-strength string 5 is connected to the anchoring frame 11 through a lock 4 at one end, and the other end is connected to the load-bearing drone 3, and is pulled to the wind turbine by the load-bearing drone 3 top height. The accelerometer 9 is installed in the middle of the high-strength string 5, and the Owen probe 6 is evenly fixed on the high-strength string 5, and is connected with the scanning valve 10 fixed on the anchor frame 11 (a mobile bracket) throu...
