The embodiment of the invention provides a winglet folding mechanism, which comprises: blade 100, retraction drive 200, first strut 300, and second strut 400;
one end of the first supporting rod 300 and one end of the second supporting rod 400 are pivoted on different positions of the blade 100, and are used for changing the angle between the blade 100 and the sea level to maximize the wind direction stress;
the other end of the first supporting rod 300 and the other end of the second supporting rod 400 are commonly provided on the folding driving device 200.
The direction of the movement of the blade 100 is controlled by the cooperation of the first support rod 300 and the second support rod 400, one end of the first support rod 300 and one end of the second support rod 400 are respectively connected with the blade 100, the other end of the first support rod 300 and the other end of the second support rod 400 are connected with the retraction driving device 200 together at the same point, the movement of the first support rod 300 and the second support rod 400 is controlled by the movement of the retraction driving device 200, and the position of the blade 100 is pushed to change by the rigid movement of the first support rod 300 and the second support rod 400. The blade 100 can be flexibly unfolded even when the offshore wind force is large, so that the application range is wider, and the wind power generation efficiency is improved.
Specifically, the retraction driving apparatus 200 includes: a gear motor 210 and a screw 220;
the gear motor 210 is connected with the screw 220 through a gear pair, and the other end of the first support rod 300 and the other end of the second support rod 400 are sleeved on the screw 220 and move along the axial direction of the screw 220.
The gear motor 210 drives the screw 220 to rotate through the gear pair, and a nut is disposed on the screw 220 and is connected to the ends of the first support rod 300 and the second support rod 400, so that the screw 220 drives the nut to move, and thus the first support rod 300 and the second support rod 400 move together.
Preferably, the retraction driving apparatus 200 further includes: a swing seat 230;
the gear motor 210 is fixed to the swing seat 230.
The swinging seat 230 mainly plays a role in swinging the retraction driving apparatus 200, and avoids the problems of deformation or unsmooth movement of the nut moving on the screw 220 due to rigid connection.
In addition, a bearing 231 for reducing the rotational friction of the screw 220 is provided in the swing seat 230.
It should be noted that, since the screw 220 is driven by the gear motor 210 to rotate by the driving gear, there are a plurality of losses caused by friction, which are unavoidable here, and in order to avoid friction losses, the bearing 231 is disposed in the swing seat 230, so that the friction losses when the screw 220 rotates in the swing seat 230 are greatly reduced.
