When the wind force is strong, the strong wind force will be gathered in the horn part of the wind gathering hood. When the wind force is too strong, the inner wall of the entire horn part is subjected to greater force. At this time, the wind gathering hood is prone to damage under strong wind force.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1 to 4In an embodiment of the present invention, a wind gathering and deflecting device for breeze power generation includes a wind gathering cover 1, one end of the wind gathering cover 1 is a trumpet-shaped structure, and the other end of the wind gathering cover 1 is a hollow straight cylinder structure, a fan blade mechanism is installed in the hollow straight cylinder portion of the wind gathering cover 1, a plurality of overflow windows 2 are equidistantly provided on the trumpet portion of the wind gathering cover 1, a rotating plate 3 is provided on the inner wall of the overflow window 2, and a rotating reset mechanism connected to the rotating plate 3 is provided on the outer wall of the trumpet portion of the wind gathering cover 1; the fan blade mechanism includes two fixing frames 4 fixedly mounted on the inner wall of the straight cylinder portion of the wind gathering cover 1, a rotating shaft 5 is rotatably mounted at the center of the two fixing frames 4, and a fan blade 6 is fixedly mounted on the periphery of the rotating shaft 5.

[0020] In this embodiment, the flowing wind enters the wind collecting cover 1 through the large opening of the trumpet portion of the wind collecting cover 1. As the inner diameter of the wind collecting cover 1 gradually decreases, the wind is gradually gathered at the center of the wind collecting cover 1 and acts on the fan blade mechanism. The fan blade mechanism rotates under the wind force. At this time, the fan blade 6 drives the rotating shaft 5 to rotate. The rotating shaft 5 and the fixed frame 4 rotate relative to each other. The rotating rotating shaft 5 drives the rotor of the generator to rotate through the speed-increasing gear in the speed-increasing gearbox, thereby achieving the wind power generation effect.

[0021] When the wind force is too strong and acts on the inner wall of the horn portion of the wind collecting cover 1, the wind force acts on the rotating plate 3 and overcomes the torque of the torsion spring 13, causing the rotating plate 3 to open. At this time, the overflow window 2 opens, and the excess wind force overflows from the overflow window 2, thereby preventing the wind force from acting on the inner cavity of the horn portion of the wind collecting cover 1 and causing damage to the wind collecting cover 1.

[0022] It should be noted that a sealing ring is provided on the inner wall of the overflow window 2 at the contact position with the rotating plate 3 to prevent wind from overflowing when the rotating plate 3 is not opened.

[0023] Please refer to Figure 2 、 Figure 3 and Figure 4 The rotation reset mechanism includes a fixed ear 7 fixedly connected to the outer periphery of the speaker part of the wind collecting cover 1 and a rotating ear 8 fixedly connected to the outer wall of the rotating plate 3. The two ends of the fixed ear 7 are integrally formed with an outwardly protruding rotating shaft 9, and the rotating shaft 9 is rotatably connected to the rotating ear 8. The rotation reset mechanism also includes a circular groove 12 opened at the docking position of the fixed ear 7 and the rotating ear 8, and the two ends of the inner wall of the circular groove 12 are fixedly connected to the two ends of the torsion spring 13.

[0024] In this embodiment, when wind force acts on the rotating plate 3, when the wind force is greater than the torque of the torsion spring 13, the rotating ear 8 drives the rotating shaft 9 and the fixed ear 7 to rotate. At this time, one end of the torsion spring 13 connected to the rotating ear 8 rotates along with the rotating ear 8, while the end of the torsion spring 13 fixed to the fixed ear 7 remains stationary. At this time, the torsion spring 13 torque is released, and as the rotating plate 3 opens, excess wind force overflows through the overflow window 2, thereby avoiding the problem of damage to the wind collecting cover 1 caused by excessive wind force.

[0025] When the wind force decreases and is less than the reset torque of the torsion spring 13 , the torsion spring 13 drives the rotating ear 8 to reset, and the rotating ear 8 drives the rotating plate 3 to reset, and the overflow window 2 is re-closed.

[0026] Please refer to Figure 4 Both ends of the fixed ear 7 are provided with an annular sealing groove 10, and the end of the rotating ear 8 close to the fixed ear 7 is integrally formed with a sealing ring 11 protruding outward, and the sealing ring 11 is rotatably connected to the inner wall of the sealing groove 10.

[0027] In this embodiment, the cooperation between the sealing ring 11 and the sealing groove 10 can increase the contact area between the rotating ear 8 and the fixed ear 7, and the provision of the sealing ring further improves the sealing of the connection, thereby avoiding the external environment from communicating with the circular groove 12, thereby ensuring the performance of the torsion spring 13 and extending the service life of the torsion spring 13.

[0028] Please refer to Figure 3 A sealing ring is provided at the contact position between the rotating shaft 9 and the rotating ear 8, and a sealing ring is provided at the contact position between the inner wall of the sealing groove 10 and the outer periphery of the sealing ring 11.

[0029] In this embodiment, a sealing ring is provided to improve the sealing performance of the contact position, thereby avoiding the problem of the rotation reset mechanism not being able to operate normally due to rust.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
