[0043] Among them, the wind measuring instrument is mounted at the other end of the swing arm 42, and the specific mounting mode will not be described, and in this embodiment, a threaded mounting is adopted, and any mounting mode can be implemented;

[0044] ​The specific operation process of the device is as follows: in actual use, the staff places the base 1 stably at the predetermined wind measurement position, pushes the scissor mechanism 2 connected with one end of the base 1 in sliding mode, so that the scissor mechanism 2 moves along the sliding groove of the base 1, and with the sliding of the one end, the scissor mechanism 2 starts to stretch, driving the lifting plate 3 connected therewith to rise slowly, when the lifting plate 3 reaches the appropriate height, stop pushing, then the staff rotates the swing arm 42 around the fixed shaft 41, adjusts the swing arm 42 from the folded state overlapped with the lifting plate 3 to the unfolded state, then installs the anemograph on the anemograph mounting rack away from the fixed shaft 41 end of the swing arm 42 with screws, when the wind measurement work is completed, the anemograph is disassembled first, and then the swing arm 42 is rotated back to overlap with the lifting plate 3, and then the scissor mechanism 2 is pushed in reverse to make it shrink, driving the lifting plate 3 to descend, and the device is completed; the device combines the scissor mechanism 2, the lifting plate 3 and the mounting assembly 4, the scissor mechanism 2 realizes flexible adjustment of the height of the lifting plate 3, and the mounting assembly 4 can realize folding and unfolding of the swing arm 42, which solves the problems of large volume and inconvenience of carrying of the traditional wind measurement mast, can adjust the wind measurement height according to actual needs, improves the applicability of the wind measurement device, reduces the transportation and installation cost, and effectively improves the work efficiency.

[0045] In some embodiments of the utility model, refer to Figure 3 、 Figure 3 and Figure 5 , the fixing mechanism 43 comprises:

[0046] The sliding block 431 is provided with a long hole one 432 in the width direction of the swing arm 42, and the sliding block 431 slides at the long hole one 432;

[0047] The connecting piece 433 is fixedly connected with the sliding block 431;

[0048] The elastic element 434 is hung on the connecting piece 433 and the fixed shaft 41 respectively at two ends, the elastic element 434 is selected from high-strength springs, one end of the spring is hung on the hook of the connecting piece 433, the other end is hung on the corresponding hook of the fixed shaft 41, and elastic ropes and the like can also be selected;

[0049] The specific working process of the fixing mechanism 43 is as follows: taking the left fixing mechanism 43 as an example, refer to Figure 5When the swing arm 42 is in the extended state, the bottom end of the swing arm 42 contacts the end of the lifting plate 3, the connecting piece 433 is below the fixed shaft 41, the slider 431 is at the bottom end of the elongated hole 432, and the elastic element 434 is in a stretched state. Under the pulling force of the elastic element 434, the swing arm 42 has a tendency to rotate counterclockwise around the fixed shaft 41. However, at this time, the lifting plate 3 blocks the swing arm 42, preventing it from rotating, thus stably maintaining the extended state. When it is necessary to rotate the swing arm 42... When the arm is switched to the folded position, the operator rotates the swing arm 42 clockwise. During the rotation, when the elongated hole 432 is directly above the fixed shaft 41, the slider 431 will move to the top of the fixed shaft 41 under the pulling force of the elastic element 434. As the rotation continues, the slider 431 will slide towards the other end of the elongated hole 432 under the pulling force of the elastic element 434. When the swing arm 42 is in the resting position, the slider 431 will have moved to the other end of the elongated hole 432. Figure 5 As shown, under the pulling force, the right-side swing arm 42 tends to rotate counterclockwise, but the lifting plate 3 blocks the swing arm 42, thus fixing it and keeping it stably in the parking position. To ensure the swing arm 42 is in the parking position, the connecting piece 433 is located below the fixed shaft 41, and a notch is made in the lifting plate 3 at an appropriate position for the swing arm 42 to pass through. The fixing mechanism 43 achieves automatic locking and switching of the swing arm 42's unfolded and parked positions through the coordinated action of the slider 431, the connecting piece 433, and the elastic piece 434. In the unfolded state, the tension of the elastic piece 434 and the blocking force of the lifting plate 3 ensure the stability of the swing arm 42. In the switching state, the tension of the elastic piece 434 automatically adjusts the position of the slider 431, eliminating the need for an additional locking device, simplifying the structure, reducing costs, and improving the convenience and stability of the swing arm 42's operation.

By introducing an electric push rod or the like as the power mechanism 5, the driving process of the scissor mechanism 2 is automated. Compared with manual pushing, it not only reduces the labor intensity of the staff, but also allows for more precise and rapid control of the height of the lifting plate 3, improving the efficiency of the deployment and adjustment of the wind measurement device, making the wind measurement operation more efficient, and further enhancing the convenience of the overall wind measurement work.
