According to the invention, when the fan blade 1 rotates with wind by taking one end close to the motor set as a fulcrum, and when the wind tangential direction is on the windward side of the fan blade 1, the process that the fan blade 1 turns from the horizontal state to the vertical state is carried out, and the fan blade 1 moves downwards under the self gravity of the gravity block 14 in the process of moving towards the vertical state, so that the pull rope 12 is changed into an arc shape from the horizontal state, and the barrier plates 4 on the pull rope 12 are changed into a centered state from the mutual interval, so that an arc-shaped plate wall is formed, and the resistance to wind can be effectively increased in the mounting hole 8, so that the external wind power part is gathered to have stronger pushing force on the fan blade 1.

When the fan blade 1 rotates to the other side until the moving track of the fan blade 1 is at the top, at the moment, the vertical state of the fan blade 1 at the bottom is changed into the horizontal state and the vertical state at the top is changed, so that the gravity block 14 resets and moves again by means of the gravity block and pulls the two pull ropes 12 to be changed from the arc shape to the straight line shape, at the moment, the multiple barrier plates 4 are far away from each other, part of external wind can rapidly pass through the mounting hole 8, and therefore the resistance to wind power is small, meanwhile, the other adjacent fan blade 1 at the external wind cutting position is combined, the gravity block 14 adjacent to and on the fan blade 1 at the wind cutting position moves downwards by means of the gravity block, so that the pull ropes 12 are changed from the horizontal state to the arc shape, and the multiple barrier plates 4 on the pull ropes 12 are changed from the mutual interval to the middle state, thereby forming an arc-shaped plate wall, and the resistance to wind can be effectively increased in the mounting hole 8, thereby reach flabellum 1 that is in the position is cut to the wind resistance grow in a plurality of flabellums 1 for external wind more has the motive force to flabellum 1, and the flabellum 1 of upwind is because a plurality of bafflers 4 keep away from each other, and partial external wind just can pass mounting hole 8 fast, and is less to the resistance of wind-force, thereby reaches the effect that promotes flabellum 1 rotation that even be in weak external wind force environment also can be quick.

When the gravity block 14 moves, the connecting rod 15 pulls the sealing plug 17 in the sealing cylinder 16, the sealing cylinder 16 is filled with liquid, so that the sealing plug 17 moves in the liquid, the liquid flows to the other side of the sealing plug 17 through the round hole 13 on the sealing plug 17, the diameter of the round hole 13 is smaller, the flow rate of the liquid on the two sides of the sealing plug 17 through the round hole 13 is slower, and the moving speed of the sealing plug 17 and the gravity block 14 is slower, so that the serious impact and collision among a plurality of baffle plates 4 can be effectively avoided when the gravity block 14 moves, meanwhile, when the gravity block 14 moves, the pull rod 5 pulls the sliding plate 6 to slide in the vent hole 2 and seal the vent hole 2, so that the acting effect of the sliding plate 6 on the baffle plates 4 is the same, when external strong wind is turbulent wind, the wind power can blow the rotating wheel 3 to rotate, and the rotating wheel 3 drives the fixedly connected screw rod 9 to rotate on the vertical plate 10, because on the stopper 11 threaded connection lead screw 9, consequently when lead screw 9 rotates, stopper 11 removes to the direction of being close to gravity piece 14, stopper 11 both ends are located the both ends of gravity piece 14, can fix gravity piece 14 in the original place, in order to avoid torrent fan leaf 1 and adjusting part to cause the damage, simultaneously because gravity piece 14 is fixed, make a plurality of bafflers 4 keep away from each other, slide 6 contracts in flabellum 1, external strong wind can flow to the back of flabellum 1 through mounting hole 8 and ventilation hole 2, consequently, the resistance to wind reduces, effectively avoid external strong wind to the damage of flabellum 1.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
