[0002] In recent years, with the steady implementation of the "dual carbon" goals, promoting the development of renewable energy utilization technology has gradually become an urgent need. Wind power generation is a green and clean way of power generation. The wind energy resources it utilizes are widely distributed, the total amount of available resources is large, and the utilization process is pollution-free. However, at present, wind resources are mainly utilized in areas with high wind speeds, while wind resources in vast areas with low wind speeds or areas that are not suitable for building wind farms are difficult to be effectively utilized. In order to make full use of the wind resources in these areas to obtain electricity, an aerial wind power generation device is designed. Using drones or helium balloons to lift wind turbines to high altitudes, convert wind energy into electrical energy, and transmit the obtained electricity to the ground via wires, it can provide more clean electricity for areas with insufficient wind resources, and can also be used in drones, electric vehicles, etc. to increase endurance. Utility Model Content
[0003] The technical problem to be solved by the utility model is to realize the utilization of wind resources in low wind speed areas or areas not suitable for building wind farms, and to create conditions for people to instantly obtain a steady supply of clean electricity. To this end, the utility model provides a foldable and retractable airborne wind power generation device that fully utilizes high-altitude wind resources to generate electricity and provides additional power for equipment or scenes such as drones, electric vehicles, and outdoor camps. For ease of explanation, the wind power generation part of the utility model takes a vertical axis wind turbine as an example, and the launch device takes a drone or a helium balloon as an example.
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0005] Taking a vertical axis wind turbine as an example, a foldable and telescopic lifting wind turbine generator device includes a lifting device, a vertical axis wind turbine and its storage device, and a wire retracting device. The vertical axis wind turbine includes a wind turbine blade, an upper telescopic rod, a lower telescopic rod, a blade telescopic slider, a blade connecting shaft, an upper connecting plate of the wind turbine, a disk generator, a lower connecting plate of the wind turbine, and an external wire. The lifting device is a drone or a helium balloon, which is connected to the upper connecting plate of the wind turbine through a boom, so as to realize the lifting of the wind turbine. In addition, the drone is equipped with four drone blades. The vertical axis wind turbine has four blades, which are evenly distributed around the blade connecting shaft at intervals of 90°, and are respectively connected to the upper telescopic rod and the lower telescopic rod in a hinged form. In addition, the upper telescopic rod and the lower telescopic rod are also respectively connected to the blade telescopic slider in a hinged form. The slider can move up and down along the slide rail set on the blade connecting shaft, so as to realize the expansion and closing of the blade, and the blade drives the blade connecting shaft to rotate. The lower part of the blade connecting shaft is connected to the disc generator, thereby driving the generator rotor to rotate and generate electricity. The lower part of the disc generator is connected to the lower connecting disc of the wind turbine. The wind turbine storage device includes a base and a protective cover. The wire retracting device includes a wheel disc, a rotating handle and a "Γ"-shaped support column.
[0006] As a further improvement of the above technical solution, the upper connecting plate of the wind turbine is rigidly connected to the suspension rod, and the blade connecting shaft is connected to the lower end of the component and can rotate independently around its central axis.
[0007] As a further improvement of the above technical solution, the upper telescopic rod and the lower telescopic rod are respectively hinged to the upper end and the lower end of the wind turbine blade, and are respectively hinged to the sliders at the lower end and the upper end of the blade connecting shaft.
[0008] As a further improvement of the above technical solution, the lower telescopic rod is a solid rod to mainly bear the gravity from the wind turbine blades, and the middle of the upper telescopic rod is hollowed out to avoid interference with the lower telescopic rod and partially bear the gravity from the wind turbine blades.
[0009] As a further improvement of the above technical solution, a small hole is opened in the middle of the lower connecting plate of the wind turbine for connecting the external wire, so as to transmit the generated electricity to the ground load or store it in the battery.
[0010] As a further improvement of the above technical solution, the upper connecting plate of the wind turbine and the lower connecting plate of the wind turbine have equal diameters and are larger than the maximum diameter of the axial cross-section after the wind turbine blades are closed, so that the upper connecting plate of the wind turbine and the lower connecting plate of the wind turbine play a supporting role when the wind turbine is stored.
[0011] As a further improvement of the above technical solution, bolt holes are drilled on both sides of the base, so that the base can be fixed according to the situation.
[0012] As a further improvement of the above technical solution, the wire retracting device is designed with a rotating handle and is rigidly connected to the wheel. The wheel is connected to the "Γ"-shaped support column and can rotate independently, thereby realizing the function of retracting and releasing the wire.
[0013] As a further improvement of the above technical solution, the drone blades on the drone are foldable to facilitate carrying and storage and save storage space.
[0014] Compared with the prior art, the advantages of the utility model are:
[0015] In the foldable and retractable wind power generation device of the utility model, the drone and the helium balloon mainly play the role of driving the vertical axis wind turbine to be launched, so that the wind turbine blades can obtain kinetic energy from the wind resources in the middle and high altitudes of 50 to 300 meters to generate electricity. When the device stops working, the drone, the helium balloon and the wind power generation device can all be retracted and folded to reduce the occupied space, and are very convenient to carry and use. When the length of the wind turbine blade is about 1.5 meters, the vertical axis wind turbine made of lightweight materials such as carbon fiber can be controlled below 35kg, and the power generation can reach 3 to 5kW. In addition, an estimate is also made based on the DJI T60 with a load capacity (excluding its own weight) of 50 to 60kg. The rated capacity of its battery is 40Ah, the rated voltage is 52.22V, and the power required by the drone is 1.74kW based on the flight time of 20min. Therefore, if the vertical axis wind turbine generates electricity while supplying power to the drone, ideally there can be more than 3.26kW of power generation, thereby realizing the long-term power generation of the wind turbine at high altitude. The foldable and telescopic wind power generation device of the utility model creates conditions for utilizing high-altitude wind energy using a foldable and telescopic portable small wind turbine, which is beneficial to providing more clean green electricity for people's production and life, and makes certain gains in energy conservation and emission reduction.
