Description

Technical Field

[0001] The utility model belongs to the technical field of wind power generation and relates to a breeze power generation device. Background Art

[0002] As the global energy crisis and environmental pollution become increasingly serious, the development and utilization of clean energy has become the focus of attention of countries around the world. Among them, wind energy, as a renewable, clean and almost emission-free energy form, has received widespread attention and application around the world. However, traditional wind power generation technology often relies on high wind speed conditions, which limits its application in areas with lower wind speeds, especially in urban and rural areas. Although wind energy resources are not scarce in these places, traditional wind turbines cannot work effectively due to the generally low wind speeds.

[0003] In recent years, the emergence of micro-wind power generation technology has provided a new solution to this problem. Micro-wind power generation technology is committed to achieving stable power generation under wind speed conditions as low as 3 meters per second or even lower, which greatly broadens the application scenarios of wind power generation. By adopting specially designed blades, optimized aerodynamic shapes and advanced control strategies, micro-wind generators are able to capture and utilize weak wind energy that was previously considered ineffective, thereby achieving energy self-sufficiency under a wider range of geographical and climatic conditions. This technology is not only suitable for remote rural areas, but also for densely populated urban environments such as rooftops, parks and streets, making it possible to build a distributed energy network.

[0004] However, although micro-wind power generation technology has made significant progress in improving energy utilization, there are still some problems that are difficult to solve. Among them, the variability of wind direction is an important factor restricting the efficiency of micro-wind power generation. Due to the unpredictability and frequent changes in wind direction, some existing micro-wind power generation devices are often difficult to design to achieve fast and accurate wind direction adaptive adjustment. As a result, when the wind direction changes, the blades of the wind turbine may not always face the wind direction, thereby reducing the efficiency of wind energy capture and affecting the power generation performance. Utility Model Content

[0005] The utility model aims to provide a breeze power generation device which can adaptively rotate according to the wind direction so that it can always generate electricity facing the wind, maximize the use of breeze resources, and effectively improve the power generation efficiency.

[0006] To solve the above technical problems, the utility model provides a micro-wind power generation device, including a base, the upper end of the base is rotatably connected to a power generation plate, and a plurality of horizontally arranged air flow channels are arranged in the power generation plate from bottom to top, one end of the power generation plate is provided with a plurality of wind collecting hoods which are connected to the air flow channels in a one-to-one manner, and each air flow channel is provided with an air outlet connected to the outside at one end away from the wind collecting hood, each air flow channel is rotatably connected with a rotating shaft, and a plurality of spiral blades are arranged on the outer periphery of each rotating shaft, a vertically arranged power generation shell is arranged on a side of the power generation plate away from the wind collecting hood, a wing plate arranged along its height direction is rotatably connected to a side of the power generation shell close to the power generation plate, a limit strip inclined away from the direction of the power generation plate is provided on a side of the wing plate close to the power generation plate, a plurality of power generation chambers which are corresponding to the air flow channels in a one-to-one manner are arranged in the power generation shell, a generator is installed in each power generation chamber, and an input shaft of each generator is connected to the corresponding rotating shaft.

[0007] By adopting the above technical solution, when a breeze is generated, the breeze blows the side of the power generation plate. Since the side area of ​​the power generation plate is large and the resistance is large, the power generation plate is blown to rotate so that it rotates to the wind collecting hood facing the wind, or one end of the power generation shell faces the wind. If one end of the power generation shell faces the wind, the wind blows the wing plate to rotate. After the wing plate rotates to tilt backward under the action of the limit strip, the resistance on both sides of the power generation shell is different. Under the action of the wind, it continues to rotate toward the wing plate until it rotates to the wind collecting hood facing the wind. At this time, the wing plate rotates to be parallel to the side of the power generation shell, and the resistance on both sides is the same. It stops rotating, and the airflow enters the wind collecting hood to gather and enters the airflow channel, pushing the spiral blades to rotate, so that the shaft rotates to drive the generator to generate electricity.

[0008] The utility model is further configured such that a mounting hole is opened downwardly at the upper end of the base, an electric slip ring is arranged in the mounting hole, a power transmission sliding shaft sliding and electrically connected with the electric slip ring is arranged downwardly at the middle part of the power generation plate, and each generator is electrically connected to the power transmission sliding shaft.

[0009] The utility model is further configured such that a partition cavity is provided between every two air flow channels in the power generation plate.

[0010] The utility model is further configured such that each wind collecting hood is in a funnel shape.

[0011] The utility model is further configured that a hollow connecting frame is arranged in each wind collecting cover, and each rotating shaft is rotatably connected to the corresponding hollow connecting frame.

[0012] The utility model is further configured such that the horizontal cross section of each air outlet is triangular.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] First, the power generation device of the utility model utilizes breeze to generate electricity, and can generate electricity stably under breeze conditions. In addition, its plate-like structure integrates multiple wind power generation components, and has a large power generation capacity, which can meet the power supply needs of households in breeze areas.

[0015] Secondly, the utility model adopts a unique structural design, which enables it to rotate adaptively under the action of wind power, and always rotates until the wind collecting cover faces the wind direction, thereby increasing the capture efficiency of wind energy, so that power generation can be achieved when there is wind, effectively increasing the power generation efficiency;

[0016] Thirdly, the present invention collects airflow through a larger wind collecting hood, and when the airflow passes through a smaller cross-section airflow channel, it can generate more sufficient thrust to drive the spiral blades to rotate and drive power generation, so that power generation can be driven even under very small wind conditions.

[0022] Example, see Figure 1-3A micro-wind power generation device includes a base 1, a power generation board 2 is rotatably connected to the upper end of the base 1, a mounting hole (not shown) is opened downwardly at the upper end of the base 1, an electric slip ring 3 is arranged in the mounting hole, and a transmission sliding shaft 4 which slides and is electrically connected with the electric slip ring 3 is arranged downwardly in the middle of the power generation board 2. Eight horizontally arranged air flow channels 5 are arranged from bottom to top in the power generation board 2, and a plurality of funnel-shaped wind collecting covers 6 which are connected to the air flow channels 5 in a one-to-one correspondence are arranged at one end of the power generation board 2. A spacing cavity 7 is arranged between each two air flow channels 5 in the power generation board 2 to increase the gap between the air flow channels 5 so that the opening of the wind collecting cover 6 can be as large as possible to increase the air intake. A hollow connecting frame 8 is arranged in each wind collecting cover 6, and an air outlet 9 which is connected to the outside is arranged at one end of each air flow channel 5 away from the wind collecting cover 6. The horizontal cross section of each air outlet 9 is triangular, so that the resistance of air discharge is smaller.

[0023] A vertically arranged power generation shell 10 is provided on one side of the power generation panel 2 away from the wind collecting cover 6, and a wing plate 11 arranged along its height direction is rotatably connected to the power generation shell 10 on one side close to the power generation panel 2. A limiting strip 12 inclined away from the power generation panel 2 is provided on the side of the wing plate 11 close to the power generation panel 2 of the power generation shell 10, so that the wing plate 11 can only be rotated to be parallel or inclined backward. A rotating shaft 13 is rotatably connected in each air flow channel 5, and each rotating shaft 13 is rotatably connected to the corresponding hollow connecting frame 8. Three spiral blades 14 are arranged on the periphery of each rotating shaft 13. Eight power generation chambers 15 corresponding to the air flow channels 5 are arranged in the power generation shell 10. A generator 16 is installed in each power generation chamber 15. The input shaft of each generator 16 is connected to the corresponding rotating shaft 13. Each generator 16 is electrically connected to the power transmission pulley shaft 4.

[0024] Working principle: When a breeze is generated, the breeze blows the side of the power generation plate 2. Since the side area of ​​the power generation plate 2 is large and the resistance is large, the power generation plate 2 is blown to rotate, so that it rotates to the wind collecting hood 6 facing the wind, or one end of the power generation shell 10 faces the wind. If one end of the power generation shell 10 faces the wind, the wind blows the wing plate 11 to rotate. Under the action of the limit strip 12, the wing plate 11 rotates to tilt backward. The resistance on both sides of the power generation shell 10 is different. Under the action of the wind, it continues to rotate toward the wing plate 11 until it rotates to the wind collecting hood 6 facing the wind. At this time, the wing plate 11 rotates to be parallel to the side of the power generation shell 10, and the resistance on both sides is the same. It stops rotating, and the airflow enters the wind collecting hood 6 to gather and enters the airflow channel 5, pushing the spiral blade 14 to rotate, so that the rotating shaft 13 rotates to drive the generator 16 to generate electricity.
