Description

Technical Field

[0001] This invention relates to a wind power device and a wind energy harvesting system, belonging to the field of energy utilization technology. Background Technology

[0002] Wind energy is a clean energy source. Amid the global oil crisis and increasingly severe environmental pollution, the development and utilization of wind energy has attracted global attention. It plays a crucial role in energy structure transformation, but existing wind energy utilization devices still suffer from numerous technical shortcomings: Firstly, wind energy harvesting efficiency is limited. Traditional devices lack targeted airflow guidance structures, making it difficult for dispersed airflow to concentrate on the energy conversion components, resulting in a large amount of wind energy not being effectively utilized. Secondly, the airflow pressure regulation accuracy is insufficient. When the wind speed changes suddenly, causing the pressure in the airflow channel to increase sharply, the existing regulation mechanism is mostly a simple opening and closing design, which cannot accurately control the exhaust volume. This can easily cause core components such as the wind blade 4 and the high-speed generator 5 to be damaged due to overload. The energy collection method is also limited. Most wind energy devices rely solely on the conversion of wind energy into electrical energy. They cannot output energy stably in windless or weak wind environments, thus limiting their applicable scenarios. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a power device and a wind energy harvesting system that utilize wind energy.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: A wind-powered device includes a collection hood and a housing. The housing has an airflow channel that communicates with the collection hood. The airflow channel is equipped with a wind energy recovery mechanism for converting wind energy into electrical energy. The wind energy recovery mechanism includes a wind blade rotatably installed in the airflow channel, and a high-speed generator is fixedly connected to the power output end of the wind blade via a coupling. The housing is provided with exhaust pipes on both sides for releasing excessive airflow pressure, and the exhaust pipes are provided with adjustment mechanisms for adjusting the amount of released airflow. The adjustment mechanism includes a connecting ring, and a plurality of evenly distributed closed plates are rotatably connected to one side of the connecting ring. The plurality of closed plates can rotate synchronously and are combined to form a sealed adjustment structure for opening and closing the exhaust pipe or adjusting the exhaust volume.

[0005] Preferably, the closing piece has a petal-shaped structure, and its corner near the inner side of the connecting ring is rotatably connected to the connecting ring via a fixed shaft. The top ends of several fixed shafts are connected to a cover ring for limiting the position.

[0006] Preferably, a toothed ring is rotatably connected to one side of the connecting ring, which is sleeved on the outside of the closing piece and rotates coaxially with the connecting ring, and a connecting rod corresponding to and connected to the closing piece is arranged around one side of the toothed ring.

[0007] Preferably, the connecting rod is an arc-shaped opening facing the airflow direction of the exhaust pipe, and is movably connected to the other corner of the closing plate and the toothed ring respectively through a pin. A gear that meshes with the toothed ring is rotatably connected to one side of the connecting ring.

[0008] Preferably, the gear is movably connected to the connecting ring via a connecting shaft, and the other end of the connecting shaft movably passes through the connecting ring and is provided with a worm gear, the top of which is provided with a worm that meshes with it.

[0009] Preferably, the exhaust pipe is equipped with a motor for driving the worm gear, and the worm gear is movably connected to the exhaust pipe via a bearing.

[0010] Preferably, at least one positioning post is provided around one side of the connecting ring, the positioning post movably passing through the toothed ring and slidingly engaging with the stroke hole on the toothed ring, for limiting the radial displacement of the toothed ring.

[0011] Preferably, the top of the housing is provided with a height-adjustable connecting column, and the top of the connecting column is provided with a photovoltaic solar panel that does not interfere with the wind energy recovery mechanism. The installation angle of the photovoltaic solar panel is adjustable.

[0012] According to another aspect of the present invention, a wind energy harvesting system for wind energy is provided for the aforementioned wind energy power device, comprising a wind energy harvesting unit connected to the power input shaft of the high-speed generator via a transmission assembly, for converting the mechanical energy of airflow driving the wind turbine blades into electrical energy. The solar energy collection unit includes an energy conversion module and an energy storage module. The energy conversion module is electrically connected to the photovoltaic solar panel and is used to convert solar energy into electrical energy. The energy storage module is used to store the electrical energy generated by the wind energy collection unit and the solar energy collection unit.

[0013] The beneficial effects of this invention are: By designing a matching structure between the collection hood and the airflow channel, the dispersed airflow can be concentrated and guided to the fan blades, increasing the force of the airflow on the fan blades. Combined with the high-efficiency energy conversion of the high-speed generator, this significantly improves wind energy utilization and solves the problems of dispersed airflow and low collection efficiency in traditional devices. The regulating mechanism adopts a multi-stage transmission structure of motor, worm gear, worm, gear, gear ring, and closing plates. The worm gear and worm drive can achieve speed reduction and torque increase, allowing the gear ring to rotate slowly and smoothly. Through the connecting rod, it drives several closing plates to open and close synchronously, which can not only completely open and close the exhaust pipe, but also precisely adjust the exhaust volume, effectively mitigating the impact of sudden changes in airflow pressure on the fan blades and high-speed generator, and extending the service life of the equipment.

[0014] Installing photovoltaic solar panels ensures that the photovoltaic solar panels and wind energy recovery mechanism do not interfere with each other. By adjusting the height of the connecting column and the installation angle of the photovoltaic solar panels, it can be adapted to the solar radiation conditions of different areas. Combined with the coordinated work of the wind energy collection unit and the solar energy collection unit, it can achieve dual energy complementary power generation and storage, which solves the limitation of a single wind energy device being unable to provide stable power in windless environments and broadens the applicable scenarios of the device.

[0015] The connection relationship and spatial layout of each component have been optimized. The closing plate adopts a petal structure and the connecting rod is designed with an arc-shaped opening facing the airflow direction, which reduces airflow resistance and ensures structural strength and smooth transmission. The device as a whole can adapt to different wind speed environments. Whether it is efficient collection under low wind speed or stable pressure under high wind speed, it can achieve good operating results. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-5 The present invention provides a power device and wind energy collection system using wind energy, including a collection cover 1 and a housing 2. The housing 2 has an airflow channel 3 connected to the collection cover 1. The airflow channel 3 is provided with a wind energy recovery mechanism for realizing the conversion of wind energy and electrical energy. The wind energy recovery mechanism includes a wind blade 4 rotatably installed in the airflow channel 3, and a high-speed generator 5 is fixedly connected to the power output end of the wind blade 4 via a coupling. The housing 2 is provided with exhaust pipes 6 on both sides for releasing excessive airflow pressure, and the exhaust pipes 6 are provided with adjustment mechanisms for adjusting the amount of released airflow. The adjustment mechanism includes a connecting ring 7, and a plurality of evenly distributed closing plates 8 are rotatably connected to one side of the connecting ring 7. The plurality of closing plates 8 can rotate synchronously and combine to form a sealed adjustment structure for opening and closing the exhaust pipe 6 or adjusting the exhaust volume.

[0021] After being collected and guided by the collection hood 1, the natural wind enters the airflow channel 3 opened on the shell 2. The airflow acts on the wind blades 4 inside the airflow channel 3, driving the wind blades 4 to rotate around their own axis. The power output end of the wind blades 4 is fixedly connected to the high-speed generator 5 through a coupling. The mechanical energy of the wind blades 4 is transmitted to the high-speed generator 5 through the coupling, and the high-speed generator 5 converts the mechanical energy into electrical energy, completing the initial conversion of wind energy into electrical energy.

[0022] Please see Figure 1-5The closing piece 8 has a petal-shaped structure. Its corner near the inner side of the connecting ring 7 is rotatably connected to the connecting ring 7 via a fixed shaft 9. The top ends of several fixed shafts 9 are connected to a cover ring 10 for limiting the position. A toothed ring 11 is rotatably connected to one side of the connecting ring 7, which is sleeved on the outside of the closing piece 8 and rotates coaxially with the connecting ring 7. A connecting rod 12 corresponding to the closing piece 8 is arranged around one side of the toothed ring 11. The connecting rod 12 is an arc-shaped opening facing the airflow direction of the exhaust pipe 6, and is movably connected to the other corner of the closing piece 8 and the toothed ring 11 via a pin 13. A gear 14 meshing with the toothed ring 11 is rotatably connected to one side of the connecting ring 7.

[0023] Please see Figure 1-5 The gear 14 is movably connected to the connecting ring 7 via a connecting shaft 15. The other end of the connecting shaft 15 movably passes through the connecting ring 7 and is provided with a worm gear 16. The top of the worm gear 16 is provided with a worm 17 that meshes with it. The exhaust pipe 6 is provided with a motor 18 for driving the worm 17. The worm 17 is movably connected to the exhaust pipe 6 via a bearing. At least three positioning posts 19 are provided around one side of the connecting ring 7. The positioning posts 19 movably pass through the gear ring 11 and slide in cooperation with the stroke hole 20 on the gear ring 11 to limit the radial displacement of the gear ring 11. The top of the housing 2 is provided with a height-adjustable connecting post 21. The top of the connecting post 21 is provided with a photovoltaic solar panel 22 that does not interfere with the wind energy recovery mechanism. The installation angle of the photovoltaic solar panel 22 is adjustable.

[0024] Please see Figure 1-5 A wind energy harvesting system is provided for the wind energy power device, including a wind energy harvesting unit connected to the power input shaft of the high-speed generator 5 via a transmission component, for converting the mechanical energy of the wind turbine blade 4 driven by airflow into electrical energy. The solar energy collection unit includes an energy conversion module and an energy storage module. The energy conversion module is electrically connected to the photovoltaic solar panel 22 and is used to convert solar energy into electrical energy. The energy storage module is used to store the electrical energy generated by the wind energy collection unit and the solar energy collection unit. Axial displacement is now observed.

[0025] The wind energy harvesting unit is connected to the power input shaft of the high-speed generator 5 through a transmission component, receiving the electrical energy converted by the high-speed generator 5 to complete the harvesting and preliminary processing of wind energy; the power conversion module of the solar energy harvesting unit is electrically connected to the photovoltaic solar panel 22, converting the solar energy absorbed by the photovoltaic solar panel 22 into electrical energy; the energy storage module is electrically connected to the wind energy harvesting unit and the solar energy harvesting unit respectively, storing the two sources of electrical energy, realizing complementary storage and stable output of wind energy and solar energy, and ensuring that the system can continuously supply energy under different meteorological conditions.

[0026] In use, natural wind is collected and guided by the collection hood 1 and enters the airflow channel 3 on the housing 2. The airflow acts on the fan blades 4 inside the airflow channel 3, driving the fan blades 4 to rotate around their own axis. The power output end of the fan blades 4 is fixedly connected to the high-speed generator 5 through a coupling. The mechanical energy of the fan blades 4 is transmitted to the high-speed generator 5 through the coupling, and the high-speed generator 5 converts the mechanical energy into electrical energy, completing the initial conversion of wind energy into electrical energy. When the airflow pressure in the airflow channel 3 exceeds a preset threshold, the motor 18 on the exhaust pipe 6 is started. The motor 18 drives the worm gear 17 connected to it to rotate (the worm gear 7 is movably connected to the exhaust pipe 6 through a bearing to ensure smooth rotation). The worm gear 17 meshes with the worm wheel 16, transmitting power to the worm wheel 16. The worm wheel 16 is connected to the connecting shaft 15. The gear 14 is driven to rotate; the gear 14 meshes with the gear ring 11, driving the gear ring 11 to rotate coaxially around the connecting ring 7. The positioning pin 19 slides along the stroke hole 20 of the gear ring 11, limiting the radial offset of the gear ring 11. When the gear ring 11 rotates, it drives the connecting rod 12 to move through the pin 13. The connecting rod 12 pulls the closing plate 8 to rotate synchronously around the fixed shaft 9, causing the sealing adjustment structure composed of several closing plates 8 to open, the exhaust pipe 6 to open and release excess airflow, and reduce the pressure in the airflow channel 3. When the pressure drops to the preset range, the motor 18 rotates in reverse, driving the closing plate 8 to rotate in reverse through the above transmission chain, reducing the opening of the exhaust pipe 6 or closing it completely, realizing dynamic and precise control of the airflow pressure. The cover ring 10 plays a limiting role on the fixed shaft 9, preventing axial displacement when the closing plate 8 rotates.

[0027] The wind energy harvesting unit is connected to the power input shaft of the high-speed generator 5 through a transmission component, receives the electrical energy converted by the high-speed generator 5, and completes the harvesting and preliminary processing of wind energy. The power conversion module of the solar energy collection unit is electrically connected to the photovoltaic solar panel 22, converting the solar energy absorbed by the photovoltaic solar panel 22 into electrical energy; The energy storage module is electrically connected to the wind energy collection unit and the solar energy collection unit respectively to store the two sources of electrical energy, realize the complementary storage and stable output of wind energy and solar energy, and ensure that the system can continuously supply energy under different weather conditions.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
