The three fixing frames 14 are arranged and uniformly distributed, and the principle that a triangle has stability is utilized, so that the fixing support 10 is stable when the wind wheel body 20 rotates.

As shown in fig. 5 and 7, the barrier module 30 is rotatably coupled to the fixing bracket 10. The barrier assembly 30 comprises a barrier plate 31, and the barrier plate 31 is arranged on one side of the wind wheel body 20 and used for blocking the incoming wind on the same side. A first horizontal connecting rod 33 and a second horizontal connecting rod 34 are arranged at two ends of the wind wheel body 20, the first horizontal connecting rod 33 and the second horizontal connecting rod 34 are vertically distributed, one end of the first horizontal connecting rod 33 is connected with one side edge of the screen plate 31, and the other end of the first horizontal connecting rod 33 is rotatably connected with the bearing sleeve 11 through a second bearing 15; one end of the second horizontal connecting rod 34 is connected to the other side of the barrier plate 31, and the other side is rotatably connected to the bearing sleeve 11 through the second bearing 15. The barrier panel 31 may be rotatably connected to the fixing bracket 10 by the first horizontal link 33 and the second horizontal link 34, and the barrier panel 31 and the wind turbine body 20 may be independently rotatable with respect to the fixing bracket 10.

The barrier assembly 30 further comprises a tail rudder plate 32, the tail rudder plate 32 is arranged on the other side of the wind wheel body 20, the tail rudder plate 32 is connected with the second bearing 15 in a rotating mode through a tail rudder connecting rod 35, and the tail rudder plate 32 passes through the second bearing 15 under the action of wind and can drive the barrier plate 31 to rotate simultaneously to adjust the barrier plate 31 relative to the position of the wind wheel body 20. In this embodiment, the first horizontal link 33 and the tail rudder link 35 are on the same straight line, and the length of the tail rudder link 35 is greater than that of the first horizontal link 33, so as to form a labor-saving lever, and when the tail rudder plate 32 is under the action of wind, the tail rudder plate 32 can drive the barrier plate 31 to rotate, so that the barrier assembly 30 is more accurate. The tail rudder plate 32 is arranged, under the action of wind, the tail rudder plate 32 can rotate to a position parallel to the wind, and meanwhile, the screen board 31 is driven to move to a corresponding position.

Further, the barrier plate 31 is a quarter cylinder with a diameter slightly larger than that of the support plate, and is used for shielding one side of the wind wheel body 20.

Referring to fig. 8 in conjunction with fig. 7, when the wind is parallel to the tail vane 32, the wind blowing from the direction away from the tail vane 32 is set as a front wind a, the wind blowing from the direction close to the tail vane 32 is set as a back wind b, and the wind blowing from other directions is set as a side wind.

When the barrier plate 31 is in a state of facing the wind a, the barrier plate 31 blocks one side of the wind wheel body 20, at this time, the other side of the wind wheel body 20 is stressed under the action of the wind, so that the concave part of the blade 211 in the wind wheel body 20 blocks the wind, at this time, the blade 211 generates a positive torque under the action of the wind, and the wind wheel body 20 starts to rotate to generate power. The part blocked by the barrier plate 31 is not influenced by the acting force of wind any more, and the reverse torque cannot be generated on the wind wheel body 20, so that the reverse acting force cannot be generated on the rotation of the wind wheel body 20, and the wind wheel body 20 can convert the wind energy into mechanical energy to a large extent. And when the airflow enters between two adjacent blades 211, because there is no central shaft between the blades 211, the airflow which is not completely converted into mechanical energy can pass through the gap between the blades 211, and because the barrier plate 31 is a quarter cylinder, the residual airflow can not be blocked, and then the residual airflow can be released and dissipated, and can not impact in the wind wheel body 20, so that the airflow is disturbed, and the conversion efficiency of the wind wheel body 20 to wind energy is improved.

Referring to fig. 9 in conjunction with fig. 7, when the barrier panel 31 is in a back-to-wind state, the concave portion of the barrier panel 31 receives the force of wind, and under the action of the wind, the barrier panel 31 starts to rotate by a certain angle relative to the wind wheel body 20, at this time, the tail vane 32 is no longer parallel to the wind direction, the tail vane 32 starts to drive the barrier panel 31 to rotate under the action of the wind until the tail vane 32 continues to be in a horizontal state with the wind, then the barrier panel 31 is in a position facing the wind again, the wind exerts an acting force on the convex surface of the barrier panel 31, and the barrier panel 31 is not driven to rotate. At the moment, the wind wheel body 20 is changed into a state that the acting force of wind on one side generates positive torque to enable the wind wheel body 20 to rotate, and wind energy is converted into mechanical energy; the part of the wind wheel body 20 shielded by the shielding plate 31 is not influenced by the acting force of wind, and the reverse torque for blocking the rotation of the wind wheel body 20 cannot be generated. And the airflow entering the wind wheel body 20 can be released and dissipated, so that the conversion efficiency of the wind wheel body 20 to wind energy is improved.

When the baffle plate 31 is in the side to the wind state, the tailboard 32 receives the power of wind to drive the baffle plate 31 moves to just wind position department, this moment the convex surface of baffle plate 32 receives the forward acting force of wind, makes one side of wind wheel body 20 begins the atress and produces the forward torque, then begins to rotate, and the opposite side of wind wheel body 20 is in the effort that does not receive the wind under the sheltering from of baffle plate 32 this moment, and sets up the baffle plate 31 is the quarter drum, can make the entering air current in the wind wheel body 20 can the dissipation release, avoids causing the influence to the rotation of wind wheel body 20.

In general, the natural wind direction may change at any time, and at this time, under the action of the tail vane 32, the barrier plate 31 may be adjusted at any time according to the change of the wind direction, so that the wind wheel body 20 may convert the wind energy at the maximum efficiency.

The present invention may be embodied in many different forms and modifications without departing from the spirit and scope of the present invention, and the above-described embodiments are intended to illustrate the present invention but not to limit the scope of the present invention.
