Fig. 3 is another schematic structural diagram of the planar linkage 20 of the wind measuring device 17 of the liftable wind turbine 10 provided by the present application.

As shown in fig. 2 and 3, the planar linkage 20 includes a first link 21 and a second link 22 connected end to end, wherein the first link 21 can mount and support the wind measuring device 17. During the movement of the plane linkage 20, a traction force can be applied to the second link 22 to pull the first link 21 to move, so that the wind measuring device 17 can be driven to lift. One end of the first connecting rod 21 is a hinged end 23, the other end of the first connecting rod 21 is a connecting end 24, and the first connecting rod 21 comprises an installation part 26 which is arranged between the hinged end 23 and the connecting end 24 and is used for installing the wind measuring device 17. Wherein the hinged end 23 of the first link 21 is movable. One end of the second link 22 is connected to the connection end 24, and the other end of the second link 22 is provided as a detachable connection end 25. One end of the second link 22 is movably connected or fixedly connected with the connecting end 24, the former facilitates the user to apply strength according to the direction of force applied, and the latter facilitates the user to apply strength directly according to the direction of force applied guided by the second link 22. The planar linkage mechanism 20 comprises a wind measuring state and a maintenance state, the height of the installation part 26 in the wind measuring state is higher than that of the installation part 26 in the maintenance state, the connection position of the detachable connection end 25 is adjusted, the first connection rod 21 can be driven to rotate in the plane of the planar linkage mechanism 20 by taking the hinge shaft of the hinge end 23 as the shaft, and the planar linkage mechanism 20 is switched between the wind measuring state and the maintenance state. The wind measuring state may refer to a state in which the wind measuring device 17 does not have a fault, such as normal operation, and the wind measuring device 17 does not need to be repaired, repaired or replaced. The windfinding situation at this time corresponds to the planar linkage 20, the detachable connection end 25 of the second link 22 is not detached, and the planar linkage 20 belongs to a closed loop mechanism. The maintenance state may be a state in which the wind measuring device 17 is out of order, and the wind measuring device 17 needs to be removed for maintenance and replacement, and the lowered planar link mechanism 20 can maintain or replace the wind measuring device 17, or the planar link mechanism 20 is ready to be raised after the wind measuring device 17 is newly installed. The maintenance state at this time corresponds to the planar linkage 20, in which the detachable connection end 25 of the second link 22 is detached and has not yet been mounted in its home position, and the planar linkage 20 also belongs to an open-loop mechanism. When the plane link mechanism 20 is in the maintenance state, the wind measuring device 17 can be located above the top of the cabin assembly 13, and the maintenance personnel can contact with the wind measuring device 17 to perform the operation at a height which can be set below 1.6m, so that the maintenance personnel can conveniently perform operation and maintenance work.

Moreover, the height of the installation part 26 in the anemometry state is higher than that of the installation part 26 in the maintenance state, and when the plane linkage mechanism 20 is in the anemometry state, the installation part is relatively high, so that the anemometry device 17 can conveniently measure the wind speed and the wind direction. And when the plane link mechanism 20 is in the maintenance state, the installation part is relatively low, and maintenance personnel can contact the wind measuring device 17, so that the maintenance is convenient. Meanwhile, a maintenance worker can conveniently apply force in the plane where the plane link mechanism 20 is located, and then conveniently control and hold the plane link mechanism 20 to finish ascending or descending, so that the plane link mechanism 20 is prevented from being damaged due to the fact that the force application direction is not right.

At this time, the wind measuring device 17 is raised to the highest position, which is advantageous for measuring the wind direction and the wind speed. In the windfinding state, the vertical rod 211 is located below the cross rod 212, and is used for not only connecting the cross rod 212 but also supporting the cross rod 212. When the first connecting rod 21 rotates along the vertical plane where the plane connecting rod mechanism 20 is located, the downward direction of the vertical plane is consistent with the gravity directions of the vertical rod 211 and the cross rod 212 respectively, so that the rotation of the vertical plane according to the gravity of the plane connecting rod mechanism 20 is facilitated, and the manpower can be saved. Meanwhile, the maintenance personnel can conveniently apply strength in the vertical plane where the plane connecting rod mechanism 20 is located, the operation stability is extremely high, the whole plane connecting rod mechanism 20 is stable, the balance is not required to be maintained by manpower, and the manual operation is convenient. In other embodiments, the plane on which the plane linkage 20 is located may also be an inclined plane inclined by a small angle with respect to the vertical plane, as long as the requirements of the wind measuring device 17 for measuring the wind speed and the wind direction can be met.

In some embodiments, the mounting portion 26 on the cross bar 212 may be a mounting recess or a mounting protrusion or a snap structure, so long as the mounting portion is adapted to the connecting structure of the wind measuring device 17, so as to complete the mounting of the wind measuring device 17.

Continuing with fig. 3, in the windmetering state, the second link 22 is inclined with respect to the vertical, and the detachable connection end 25 is inclined to a side near the hinge end 23.

The second connecting rod 22 can move relative to the first connecting rod 21 due to the hinged arrangement, the degree of freedom of the second connecting rod 22 is increased, and therefore maintenance personnel can operate the second connecting rod 22 conveniently. In some embodiments, the second link 22 includes a hinge joint, the connecting end 24 of the first link 21 may be two hinge plates, and the hinge joint of the second link 22 is hinged in the two hinge plates of the first link 21 by a hinge shaft, and the hinge joint and the two hinge plates rotate relative to each other about the hinge shaft.

Fig. 6 to 8 are schematic structural diagrams of the planar link mechanism 20 of the wind measuring device 17 of the liftable wind turbine 10 provided by the present application in a transition state. As shown in fig. 6 to 8, during the switching between the maintenance state and the anemometry state, the relative positions of the cross bar 212 and the vertical bar 211 change as the planar linkage 20 descends or ascends in the plane. The planar linkage includes a transition state between the weatherometer state and the maintenance state, which includes a state in which the planar linkage 20 is lowered or raised in a plane. Assuming that the windward state of the planar linkage 20 shown in fig. 3 is the initial state of 0 °, for example, the following is given: as shown in fig. 6, when the planar linkage 20 rotates 45 ° counterclockwise from 0 ° along the vertical plane, it carries the anemoscope to rotate 45 ° counterclockwise along the vertical plane, and the anemoscope starts to descend. As shown in fig. 7, when the planar linkage 20 continues to rotate 90 ° counterclockwise along the vertical plane, it carries the anemoscope to continue to rotate 90 ° counterclockwise along the vertical plane, and further descent of the anemoscope is achieved. As shown in fig. 8, as the planar linkage 20 continues to rotate 135 ° counterclockwise along the vertical plane, it continues to rotate 135 ° counterclockwise along the vertical plane with the anemoscope, achieving a further descent of the anemoscope to achieve the maintenance state as shown in fig. 9. After the anemorumbometer is re-installed on the planar linkage mechanism 20, when the planar linkage mechanism 20 rotates and rises along the vertical plane, the anemorumbometer can be driven to rotate and rise along the vertical plane clockwise, and finally return to the initial position, i.e. the 0 ° state (see fig. 3). Of course, the direction and angle of counterclockwise rotation when descending and the direction and angle of clockwise rotation when ascending are not limited, and are only illustrated and not limited herein.
