Description

Technical Field

[0001] This invention belongs to the field of solar power generation and wind power generation technology, and specifically relates to a combined foldable solar and wind power generation device and method. Background Technology

[0003] The demand for distributed mobile power sources is experiencing explosive growth. On the one hand, frequent extreme weather events are leading to more grid outages, causing significant inconvenience and economic losses to residents and society. On the other hand, with the increase in outdoor camping, field exploration, border patrols, and emergency disaster relief activities, a stable power supply in off-grid environments has become a necessity. Therefore, developing a highly adaptable, portable, and easily stored distributed power generation device is of significant practical importance.

[0004] Currently, complementary power generation devices that combine solar photovoltaic and wind power have emerged in the industry, aiming to solve the problem that single energy sources are greatly limited by climate conditions. However, existing wind-solar hybrid systems still face numerous technical bottlenecks in practical applications, making it difficult to meet the requirements of use in complex environments. Specifically, these bottlenecks manifest in the following ways: First, insufficient environmental adaptability and safety. Most existing systems are fixed structures, lacking wind speed sensing and self-protection mechanisms. In strong winds, the excessively large windward area leads to a surge in wind load, easily causing blade breakage or tower overturning. The equipment has poor wind resistance, posing safety hazards. Second, rigid spatial structures and poor portability. Traditional wind-solar hybrid systems typically employ a split design, with wind turbines and solar panels independently mounted. This results in a large overall structure with a high center of gravity, making storage, transportation, and relocation extremely inconvenient and unsuitable for field operations or military scenarios requiring frequent relocation. Third, poor aerodynamic performance and low power generation efficiency. Existing vertical axis wind turbine blades mostly adopt a flat or straight design, resulting in significant wind resistance when airflow passes over the blades and a tendency for airflow separation. This not only makes it difficult for the blades to start in low-speed winds but also reduces the rotational torque at the same wind speed, thus affecting wind energy utilization and power generation efficiency. Summary of the Invention

[0005] The present invention provides a combined foldable solar and wind power generation device and method to address the above-mentioned problems.

[0006] To achieve the above objectives, the present invention employs the following technical solution: A modular, foldable solar and wind power generation device includes a base, which is a hollow cylindrical structure. A generator is fixedly installed at the center of the bottom of the base. The rotor of the generator is fixedly connected to the output shaft of a speed increaser, and the input shaft of the speed increaser is fixedly connected to the lower end of a central rod. A through hole is provided on the upper surface of the base for the central rod to pass through. A conductive slip ring is provided between the through hole and the central rod. A retaining ring structure is fixedly installed on the upper part of the central rod. Six sets of telescopic structures are fixedly connected to the retaining ring structure in a staggered manner around its circumference. Each set of telescopic structures includes a first connecting rod. A first servo motor is fixedly installed on the other end of the first connecting rod. The output shaft of the first servo motor points vertically downwards. The first connecting rod has an opening slot for mounting the first servo motor. The output shaft of the first servo motor passes through the opening slot and is fixedly connected to the servo disc. The servo disc is fixedly mounted on one end of the upper surface of the second connecting rod. A second servo motor is fixedly mounted on the other end of the upper surface of the second connecting rod. The output shaft of the second servo motor is horizontally outward and is fixedly connected to a rocker arm. The rocker arm is fixedly mounted at the center of the side of the blade structure. A rocker arm hole for mounting the rocker arm is opened at the center of the side of the blade structure. The blade structure is an inwardly curved arc structure. Slots are opened on both the left and right sides of the outer arc surface of the blade structure. The slots are used to mount solar panels. The solar panels and the generator are used to charge the energy storage battery.

[0007] Furthermore, the arc bending angle of the blade structure is 10°.

[0008] Furthermore, the blade structure adopts a honeycomb sandwich structure.

[0009] Furthermore, two photosensitive sensors and one wind speed and direction sensor are installed on the upper surface of the base. The two photosensitive sensors are located on both sides of the central rod. A control module is installed inside the base. The output terminals of the photosensitive sensors and the wind speed and direction sensor are connected to the input terminal of the control module. The output terminal of the control module is connected to the first and second servo motors via conductive slip rings to control the first and second servo motors. The output terminal of the control module is connected to the control port of the wind-solar hybrid controller. The power generation input port of the wind-solar hybrid controller is connected to the solar panel and the generator, respectively. The charging output port of the wind-solar hybrid controller is connected to the energy storage battery to control the charging of the energy storage battery. The energy storage battery is used to power the control module, the wind-solar hybrid controller, the first servo motor, the second servo motor, the photosensitive sensors, and the wind speed and direction sensor.

[0010] Furthermore, the retaining ring structure includes a retaining ring with six sets of outwardly extending pairs of connecting plates arranged alternately around its circumference. A mounting groove is formed in the middle of each pair of connecting plates, the mounting groove matching the thickness of one end of the first connecting rod. Two sets of small holes are formed on the connecting plates, communicating with the mounting groove. The first connecting rod has mounting holes corresponding to the small holes. Rivets are installed in the small holes and mounting holes to achieve a fixed installation of the retaining ring structure and the first connecting rod.

[0011] Furthermore, six drilled holes are evenly spaced on the retaining ring, staggered with those on the connecting plate, and a first mounting hole corresponding to the drilled holes is formed on the central rod. Self-tapping screws are installed in the drilled holes and the first mounting hole to achieve fixed installation of the retaining ring and the central rod.

[0012] Furthermore, a rudder disc groove for mounting the rudder disc is provided on the upper surface of one end of the second connecting rod.

[0013] Furthermore, bolts are installed inside the fixing ears to secure the base to the platform.

[0014] A combined foldable solar and wind power generation method includes the following steps: S1: High wind protection condition When the wind speed is ≥10m / s, both the first and second servo motors remain in their initial state, the first connecting rod and the second connecting rod are perpendicular, the system stops working and is in a retracted state, and the device is locked to avoid structural overload damage caused by high wind speed. S2: Pure wind power generation mode When 7 m / s < wind speed < 10 m / s and light intensity < 1000 lux, the control module controls the wind-solar hybrid controller to charge the energy storage battery only through the generator. At the same time, the control module drives the first servo motor to rotate 90° clockwise, so that the first connecting rod and the second connecting rod are in a straight line. The second servo motor remains in the initial state, thereby generating wind power. S3: Pure solar power generation mode When the light intensity is greater than 1000 lux and the wind speed is less than 7 m / s, the control module controls the wind-solar hybrid controller to charge the energy storage battery only through the solar panel. At the same time, the control module drives the first servo motor to rotate 90° clockwise so that the first connecting rod and the second connecting rod are in a straight line. The second servo motor adjusts the angle in real time according to the light information collected by the photosensitive sensor to realize the automatic light tracking of the blade structure, thereby improving the power generation efficiency. S4: Combined solar and wind power generation mode When the wind speed is <7 m / s and the irradiance is <1000 lux, or when 7 m / s < wind speed <10 m / s and the irradiance is >1000 lux, the system enters a solar and wind power co-generation mode. The control module controls the wind-solar hybrid controller, which charges the energy storage battery through the solar panels and generator. At the same time, the control module drives the first servo motor to rotate 90° clockwise, so that the first connecting rod and the second connecting rod are in a straight line. The second servo motor adjusts the angle in real time according to the irradiance information collected by the photosensitive sensor. This not only realizes the automatic tracking of the blade structure, but also realizes the synergistic utilization of wind and solar resources, improving the overall power generation efficiency.

[0015] Compared with the prior art, the present invention has the following advantages: This invention employs a telescopic structural design: On one hand, the first servo motor can control the second connecting rod to extend and retract based on wind speed and direction information. The second servo motor, based on real-time collected light intensity and orientation, precisely adjusts the blade structure angle, automatically switching between four operating modes: high wind protection, pure wind power generation, pure solar power generation, and combined solar and wind power generation, significantly improving the device's environmental adaptability. On the other hand, the dual servo motors can independently drive the second connecting rod and the blade structure to fold inward for storage, effectively enhancing the device's portability and transportation convenience.

[0016] The blade structure of this invention adopts a honeycomb sandwich configuration, which can significantly reduce the overall weight. Simultaneously, by using computational fluid dynamics (CFD) simulations to model the airflow field under different curvatures, and through simulation comparisons of parameters such as drag and torque, the bending angle of the blade structure was optimized to 10°. This design effectively reduces the wind resistance on the blade, making the blade rotate more smoothly at the same wind speed. Furthermore, the solar panels are embedded in pre-set slots on the outer curved surface of the blade, allowing for power generation in various outdoor environments, improving system operational continuity, fully leveraging the advantages of wind-solar hybrid power generation, and thus enhancing energy utilization and power generation stability.
