[0011] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0012] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0013] Example 1 This embodiment provides an automatic air guiding device for a wind-concentrating hood. Specifically... Figure 1 and Figure 2 This is a structural diagram of the automatic air guiding device for the wind concentrator; combined with Figure 1 and Figure 2 The air guiding device includes: a fixed cylinder 1, a sleeve 2, a sleeve central shaft 4, a rotating cover 5, a strip-shaped tail fin 10, and an axial limiting device for the rotating cover 5. In this embodiment, regarding the structure of the aforementioned rotating cover 5, it should be noted that: Combination Figure 1 and Figure 2 The rotating cover 5 is a hollow cylindrical groove structure with a circular through hole at the center of the top and a completely open bottom; the size and position of the circular through hole are adapted to the central shaft 4 of the sleeve. Combination Figure 1 and Figure 2 The top lower surface of the rotating cover 5 is equipped with multiple first universal balls 6-1, the inner side of the rotating cover 5 is equipped with multiple second universal balls 6-2, and the top upper surface of the rotating cover 5 is equipped with multiple third universal balls 6-3.

[0014] In this embodiment, as Figure 1 As shown, the axial limiting device of the aforementioned rotating cover 5 includes: a fixing plate 8 and a central shaft fixing block 7; Regarding the aforementioned structural connection of sleeve 2, sleeve central shaft 4, central shaft fixing block 7, and fixing plate 8, it should be noted that: like Figure 1 As shown, the bottom end of the sleeve center shaft 4 is fixed to the top surface of the sleeve 2, the center shaft fixing block 7 is fixed to the top end of the sleeve center shaft 4, the fixing plate 8 is fixed to the top surface of the center shaft fixing block 7 based on the fixing plate bolt 9, and the sleeve 2 is fixed and nested on the outside of the fixing cylinder 1 based on the sleeve fixing bolt 3.

[0015] Among them, the fixed cylinder 1 plays a key role in fixing the bottom of the equipment, providing a stable installation benchmark for the entire set of equipment, and ensuring that the device will not shift or shake under the action of wind.

[0016] In this embodiment, regarding the assembly of the aforementioned rotating cover 5, the following should be noted: like Figure 1 As shown, the rotating cover 5 is fitted and nested on the outside of the sleeve 2. At the same time, the rotating cover 5 is axially limited based on the fixing plate 8 to ensure that the rotating cover 5 always rotates stably within the preset trajectory.

[0017] Combination Figure 1 and Figure 2 Multiple first universal balls 6-1 are evenly distributed on: the vertical projection surface of the top surface of the sleeve 2 onto the lower top surface of the rotating cover 5; multiple second universal balls 6-2 are evenly distributed on: the vertical projection surface of the outer side of the sleeve 2 onto the inner side of the rotating cover 5; multiple third universal balls 6-3 are evenly distributed on: the vertical projection surface of the bottom surface of the fixing plate 8 onto the upper top surface of the rotating cover 5. Combination Figure 1 and Figure 2 The rotating cover 5 is in contact with the top surface of the sleeve 2 based on the first universal ball 6-1, the rotating cover 5 is in contact with the outer side of the sleeve 2 based on the second universal ball 6-2, and the rotating cover 5 is in contact with the bottom surface of the fixed plate 8 based on the third universal ball 6-3.

[0018] In this embodiment, the first universal ball 6-1, the second universal ball 6-2, and the third universal ball 6-3 are used as rotating carriers, which greatly reduces the frictional resistance during the rotation of the rotating cover 5 and ensures that the fit between the rotating cover 5 and the sleeve 2 will not be shifted or deformed, thereby strictly ensuring the accuracy of the rotation action.

[0019] In this embodiment, combined with Figure 1 and Figure 2 The wind-concentrating cover 12 is fixed to the top surface of the rotating cover 5 based on the wind-concentrating cover bracket 11, and the strip-shaped tail wing 10 of a preset length is fixed to the outer side of the rotating cover 5. It should be noted that the extension direction of the strip-shaped tail wing 10 is opposite to the windward side of the wind-concentrating cover 12.

[0020] In this embodiment, by setting a strip tail 10, the direction of the strip tail 10 is controlled based on the wind direction and airflow. When the wind direction changes, the strip tail 10 will drive the rotating cover 5 to rotate under the thrust of the airflow. In this way, by tracking the wind direction change in real time, the wind-gathering cover 12 is always at the best windward angle, which greatly improves the wind energy capture efficiency.

[0021] The automatic wind-guiding device for the wind-collecting shroud described in Embodiment 1 includes: a central shaft 4 of the sleeve fixed to the top surface of the sleeve 2; a rotating shroud 5 nested within the sleeve 2, and the rotating shroud 5 movably contacts the top / outer surface of the sleeve 2 based on the first universal ball 6-1 / second universal ball 6-2; a wind-collecting shroud 12 fixed to the top surface of the rotating shroud 5, and a strip-shaped tail fin 10 fixed to the outer surface of the rotating shroud 5; under the condition that "the extension direction of the strip-shaped tail fin 10 is opposite to the windward side of the wind-collecting shroud 12", when the wind direction changes significantly, the wind force drives the strip-shaped tail fin 10 to rotate. At the same time, the rotating shroud 5 rotates accordingly under the rolling action of the first universal ball 6-1 and the second universal ball 6-2 until the windward side of the wind-collecting shroud 12 faces "the direction from which the wind blows", so as to achieve: adjusting the windward side of the wind-collecting shroud in combination with the real-time external wind direction to improve the wind power generation efficiency; For the automatic air guiding device of the wind-gathering hood described in the aforementioned embodiment 1, the central shaft fixing block 7 is fixed to the top of the central shaft 4 of the sleeve, and the fixing plate 8 is fixed to the top surface of the central shaft fixing block 7; the rotating hood 5 is movably contacted with the bottom surface of the fixing plate 8 based on the third universal ball 6-3; thus, the rotating hood 5 is axially limited during the rotation process based on the fixing plate 8 to ensure the overall operational stability of the automatic air guiding device of the wind-gathering hood.
