[0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Since wind energy is a clean, pollution-free renewable energy source, the use of wind power generation is very environmentally friendly, and the wind energy reserves are huge, so it is increasingly valued by countries around the world. According to industry statistics, the advantages of wind power are: for every doubling of production capacity, the cost will drop by 15%, and the cost-effectiveness of wind power applications is forming a competitive advantage over coal-fired power and hydropower. The wind power generation equipment commonly used in the prior art is greatly affected by seasonality. Wind energy resources are mainly concentrated in certain specific areas, such as the northwest, northeast, north China and coastal areas. In addition, not only does the seasonal change of wind energy resources affect the stability of wind power generation, but the change of wind volume in a day is also very large. It is impossible to achieve continuous power generation 24 hours a day, resulting in a long period of time when the wind turbine is shut down or not fully loaded, resulting in reduced power generation efficiency. Therefore, it is necessary to optimize and improve. Summary of the invention

The working performance of the equipment is stable and the power generation efficiency is guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0028] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0029] A breeze power generation device, such as Figures 1 to 8As shown, it includes a wind collecting box 1, a wind guide tube 3 is provided on the lower side of the wind collecting box top plate 2, and an axial flow wind turbine 4 is installed in the wind guide tube; a spoiler tube 5 is provided on the upper side of the wind collecting box top plate corresponding to the wind guide tube, and the inner cavity of the wind guide tube is communicated with the inner cavity of the spoiler tube; a flow guiding structure 6 is provided on the periphery of the spoiler tube, and several spoilers 7 of different heights are provided in the spoiler tube, and each spoiler is arranged obliquely, and a cover plate 22 is provided on the upper end of the spoiler tube. For example, 2-5 spoilers are provided in the spoiler tube (open side), and the end of the spoiler extends out of the spoiler tube opening. The spoiler tube is arranged vertically, and its rear side is open 8, and the opening 9 of the wind collecting box is opposite to the opening direction of the spoiler tube. For example, the cross-sectional area of ​​the inner cavity of the wind collecting box gradually increases from its opening side to the back plate side.

[0030] The air guide includes an air inlet section 10 and an air outlet section 11. The large opening end 12 of the air inlet section faces downward, and the large opening end 13 of the air outlet section faces upward. The connection between the air inlet section and the air outlet section forms a neck 14. The generator impeller 15 of the axial flow wind turbine is arranged corresponding to the neck. When working, it can improve the driving effect of the airflow on the generator impeller and improve the power generation efficiency. The cross section of the large opening end 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 is consistent with the cross section of the spoiler.

[0031] The cross section of the spoiler is a U-shaped structure, including a left plate 16, a right plate 17, and an arc plate 18 between the two. Both sides of each spoiler are fixed to the left plate and the right plate, respectively, and there are air holes between the spoiler and the arc plate. The guide structure includes inner guide blades 19 and outer guide blades 20 symmetrically arranged on both sides of the spoiler, respectively. There are airflow channels between the inner guide blades and the spoiler, and between the outer guide blades and the inner guide blades. 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.

[0032] When the airflow blowing through the air guide tube enters the air outlet section, it will produce a "Venturi effect". The airflow 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 powerfully, thereby improving the power generation efficiency in a breeze environment. In addition, the spoiler tube disperses the airflow in the air guide tube in the height direction, so that the part of the airflow entering the spoiler tube 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.

[0033] The top plate of the air collecting box adopts an arc-shaped structure, 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 airflow channel of the guide structure more smoothly. An inclined guide surface is provided on the side of the large opening end of the air outlet section away from the spoiler (i.e., the rear side of the large opening end of the air outlet section), and the inclination angle of the guide surface is roughly equal to the inclination angle of the spoiler. In an optional embodiment, an inclined outer eaves 21 is provided at the opening end of the air inlet section, and the junction between the outer eaves and the air inlet section has a smooth transition, and the natural wind is gathered by covering the outer eaves, thereby increasing the air intake.

[0034] The edges of both sides of the top plate are provided with upward guide plates 23, that is, the two guide plates are symmetrically arranged on both sides of the opening of the air collecting box, and the guide plates cooperate with the guide structure to play the role of guiding the airflow, so that after the airflow passes through the guide structure, a suction effect is formed behind the spoiler cylinder. Since the cross-sectional area of ​​the air outlet is larger than the cross-sectional area of ​​the spoiler cylinder, the airflow discharged from the air outlet will partially pass through the spoiler cylinder, and the airflow directly discharged from the air outlet will be affected by the suction effect behind the above-mentioned guide structure. Therefore, the airflow in the air guide cylinder will be affected by the "Venturi effect" and accelerate the movement, thereby improving the efficiency of wind power generation.

[0035] The invention has a reasonable structural design and can be used as an infrastructure for wind power generation. It is simple and convenient to install and use, and occupies a small space. The external natural wind enters through the opening of the wind collecting box, and when passing through the air guide tube, it will produce a "Venturi effect" to accelerate the airflow, thereby ensuring that the axial flow wind generator in the guide tube can start to generate electricity. At the same time, since the natural wind on the upper side of the wind collecting box passes through the air flow channel of the material guide structure, a suction effect will be generated behind the spoiler tube, so that the airflow discharged through the air guide tube is accelerated again, further improving the gas flow rate, and increasing the driving force on the axial flow wind generator in the guide tube, so that the generator can be driven to generate wind power in a breeze environment. The working performance of the equipment is stable and the power generation efficiency is guaranteed.

[0036] 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 principle of the present invention should be included in the protection scope of the present invention.
