Description

Technical Field

[0001] The invention belongs to the technical field of wind power generation, and in particular relates to a wind guide device for wind power generation. Background Art

[0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. The power generation equipment commonly used in existing technologies is large in size, occupies a large area of ​​land, is inconvenient to transport and install, and its power generation efficiency is greatly affected by seasonality. Since the wind volume varies greatly throughout the day, it is impossible to achieve continuous power generation 24 hours a day. As a result, wind turbines will be shut down or operate at less than full load for a long period of time. It is particularly important to improve the power generation efficiency in a breeze environment. Therefore, it is necessary to optimize and improve the existing power generation equipment.

In addition, the terms "first", "second" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, features defined as "first", "second" and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0023] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art can understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0025] A wind guide device for wind power generation, such as Figures 1 to 7 As shown, it includes an air collecting box 1, a spoiler 3 is provided on the upper side of the top plate 2 of the air collecting box, an air outlet 4 is provided on the top plate corresponding to the spoiler, a guide structure is provided on the periphery of the spoiler, and several spoilers 5 of different heights are provided inside the spoiler; the spoiler is arranged vertically, and its opening 6 is opposite to the opening 7 of the air collecting box; the guide structure includes inner guide blades 8 and outer guide blades 9 symmetrically arranged on both sides of the spoiler, and air flow channels are left between the inner guide blades and the spoiler, as well as between the outer guide blades and the inner guide blades. A cover plate 10 is provided at the upper end of the spoiler, and the top of each inner guide blade and the top of each outer guide blade are fixed to the cover plate.

[0026] During use, an air duct is installed on the lower surface of the air collecting box top plate at a position corresponding to the spoiler, so that the air duct and the spoiler are connected. The air duct includes an air inlet section 11 and an air outlet section 12. The large opening end 13 of the air inlet section faces downward, and the large opening end 14 of the air outlet section faces upward. The connection between the air inlet and air outlet sections forms a neck. In fact, this air vent is the part that protrudes outward from the large opening end of the air outlet section of the air duct. An axial-flow wind turbine is installed in the air duct, and the generator impeller of the axial-flow wind turbine is arranged corresponding to this neck. During operation, it can enhance the driving effect of the airflow on the generator impeller, thereby improving power generation efficiency.

[0027] When the air flow blowing through the air guide tube enters the air outlet section, it will produce a "Venturi effect". The air flow is quickly discharged from the large opening end of the air outlet section, which has a "suction" effect on the natural wind in the air inlet section, so that the axial flow fan in the air guide tube is driven more forcefully, thereby improving the power generation efficiency in a breeze environment. In addition, the spoiler disperses the air flow in the air guide tube in the height direction, so that the part of the air flow entering the spoiler can be more evenly affected by the above-mentioned "suction" effect at the same time, which is conducive to further quickly increasing the flow rate of the gas in the guide tube.

[0028] The top of the spoiler and the top of each blade of the guide structure are welded and fixed to the cover plate, and the structure is stable and reliable. The top plate is an arc-shaped plate, and its side close to the opening of the air collecting box is lower than its side close to the back plate of the air collecting box, so that the airflow enters the air flow channel of the guide structure more smoothly. The cross-section of the large opening end of the air outlet section of the air guide is larger than the cross-section of the spoiler, and the front side of the large opening end of the air outlet section is consistent with the cross-section shape of the spoiler. Several legs 15 are symmetrically provided at the lower end of the air collecting box.

[0029] Since the cross-sectional area of ​​the air outlet is larger than that of the spoiler, part of the airflow discharged from the air outlet will pass through the spoiler, and the airflow discharged directly from the air outlet will be affected by the suction effect behind the above-mentioned guide structure. Therefore, the airflow in the air guide will be affected by the "Venturi effect" and accelerate its movement, thereby improving the efficiency of wind power generation.

[0030] The invention has a simple structure and a reasonable design. The external natural wind enters through the opening of the wind collecting box and produces a "Venturi effect" when passing through the air guide tube, thereby accelerating the airflow. The natural wind on the upper side of the wind collecting box passes through the air flow channel of the material guide structure, and a suction effect is generated behind the spoiler tube, so that the airflow discharged through the air guide tube is accelerated again, thereby increasing the gas flow rate, so that even in a breeze environment, a larger wind force can be formed in the air guide tube, thereby driving the generator to generate electricity.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
