Description

Technical Field

[0001] This invention relates to the field of power supply technology for field operation equipment, and in particular to a vehicle-mounted wind-solar hybrid unmanned aerial vehicle (UAV) field operation power supply system. Background Technology

[0002] With the booming development of the low-altitude economy, the application of drones and other low-altitude aircraft in field operations is becoming increasingly widespread. From vegetation irrigation and pesticide spraying to fire reconnaissance in forest fire prevention, the reliance on drones in various field operations continues to rise. However, the power supply problem for drones in field operations remains a core bottleneck restricting their effectiveness: on the one hand, field operation environments are often far from power grid coverage, requiring drones to frequently stop to change batteries, seriously affecting the continuity of drone operations; on the other hand, traditional portable power generation equipment not only suffers from noise pollution and high fuel costs, but its energy supply stability is also insufficient to meet the needs of long-term field operations.

[0003] In existing technologies, some solutions attempt to install photovoltaic power generation devices on vehicles to power drones, but these have limitations such as a fixed solar surface area and low energy collection efficiency. Furthermore, relying solely on solar power is significantly affected by weather and sunlight conditions, and power outages are likely to occur on cloudy or rainy days or when sunlight is insufficient. In addition, the reliability of drones and power generation equipment is insufficient when vehicles are in motion or on complex road conditions in the wild, making them susceptible to damage from bumps and vibrations, posing a potential threat to operational safety.

[0019] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1-9As shown, a vehicle-mounted wind-solar hybrid unmanned aerial vehicle (UAV) 6 field operation power supply system includes a vehicle 1, preferably an all-terrain pickup truck. The vehicle 1 is divided into a cab and a cargo box. A wind power generation mechanism 2 is installed at the front end of the cargo box, and an energy storage mechanism 4 is installed on the left, right and rear sides of the cargo box. A photovoltaic power generation mechanism 3 is installed on the top of the cab and the side wall of the cargo box. A fixing mechanism 5 is installed at the center of the cargo box, and a UAV 6 is placed on the fixing mechanism 5. Preferably, the UAV 6 is a Class IV UAV. The wind power generation mechanism 2 and the photovoltaic power generation mechanism 3 are both electrically connected to the energy storage mechanism 4. The energy storage mechanism 4 is electrically connected to the vehicle 1 and the fixing mechanism 5 respectively.

[0022] Vehicle 1 adopts a hybrid electric power system to achieve the goal of long endurance. When wind and solar energy resources are sufficient, the system can not only power the UAV 6, but also drive the electric power part of the vehicle. When wind and solar power generation is insufficient, the fuel engine starts and charges the energy storage device 4, thus forming a three-level energy security system of "wind and solar - battery - fuel".

[0023] The fixing mechanism 5 includes a fixing base 501, which is installed at the center of the interior of the vehicle 1 compartment. A buffer rubber pad 502 is installed on the top of the fixing base 501, and a fixing frame 503 is installed on the top of the buffer rubber pad 502. The fixing frame 503 provides a stable parking support for the drone 6, ensuring the safety and stability of the equipment in transportation or standby mode. The drone 6 is placed on the fixing frame 503, and a charging port 504 is installed on the fixing frame 503. The drone 6 is electrically connected to the charging port 504, and the charging port 504 is electrically connected to the energy storage mechanism 4.

[0024] The energy storage mechanism 4 includes a first battery pack 401 and a second battery pack 402. Battery storage compartments 404 are installed at the rear end and on the left and right side walls of the vehicle 1. The battery storage compartments 404 are equipped with heat dissipation holes. The first battery pack 401 is installed inside the battery storage compartment 404 at the rear end of the vehicle 1. The two sets of second battery packs 402 are installed inside the battery storage compartments 404 on the left and right sides of the vehicle 1. A cable 403 is installed inside the vehicle 1. One end of the cable 403 is electrically connected to the first battery pack 401 and the second battery pack 402 respectively. The other end of the cable 403 is electrically connected to the vehicle 1, the charging port 504, the wind power generation mechanism 2 and the photovoltaic power generation mechanism 3 respectively. A charge and discharge manager (not shown in the figure) is also provided to achieve efficient power regulation.

[0025] The wind power generation mechanism 2 includes a generator body 204, blades 201, and telescopic components. Telescopic components are installed on both sides of the front end of the vehicle 1. The generator body 204 is installed on the top of the telescopic components. Preferably, the generator body 204 is a D+S type vertical axis wind turbine. A main shaft 202 is installed on the top of the generator body 204, and the blades 201 are installed on the top of the main shaft 202. A brake 203 is installed on one side of the generator body 204. A bevel gear is installed on the brake 203. A bevel gear is sleeved on the main shaft 202. The two bevel gears mesh with each other.

[0026] A first conductor 205 is installed on the generator body 204. A winch 206 is installed inside the vehicle 1 near the telescopic component. Driven by the telescopic component, the winch 206 enables the stable winding and unwinding of the first conductor 205. This ensures that the first conductor 205 continuously transmits electrical energy and allows the first conductor 205 to be adjusted according to the height of the telescopic component, avoiding damage caused by the asynchronous movement of the first conductor 205 and the equipment. At the same time, the winch 206 installed near the telescopic component in the vehicle 1 assists the winding of the first conductor 205 through mechanical transmission, making the winding process faster and the arrangement more neat. This effectively avoids equipment operation problems caused by the first conductor 205 being tangled or loose. The other end of the first conductor 205 is wound on the winch 206 and is electrically connected to the cable 403.

[0027] The telescopic assembly includes a hydraulic base 207, which is installed on the left and right sides of the front end of the vehicle 1 compartment. A hydraulic rod 208 is installed on the top surface of the hydraulic base 207, and the generator body 204 is installed on the top of the hydraulic rod 208.

[0028] The photovoltaic power generation mechanism 3 includes a first photovoltaic panel 301 and a second photovoltaic panel 302. The first photovoltaic panel 301 is installed on the top of the front of the vehicle 1, and the size of the first photovoltaic panel 301 is adapted to the size of the front of the vehicle 1 to ensure that it fits tightly with the top surface of the front of the vehicle after installation and remains stable during vehicle movement. The top of the left and right side walls of the vehicle 1 are equipped with hinge shafts 303, and the second photovoltaic panel 302 is hinged to the hinge shafts 303.

[0029] The second photovoltaic panel 302 consists of two single-sided photovoltaic panels, which are hinged together by a hinge shaft 303. The whole structure adopts a cross-link folding structure design. A gear 304 is installed at one end of the second photovoltaic panel 302. A rack 305 and a power source are set on the side wall of the carriage. The gear 304 and the rack 305 mesh with each other. The power source drives the rack 305 to extend and retract, which precisely controls the hinge shaft 303. This allows the second photovoltaic panel 302 to be flexibly unfolded and folded within the range of 0°-180°. When unfolded, it can maximize the use of the light area, and when folded, it can reduce the space occupation.

[0030] A second conductor is installed on both the first photovoltaic panel 301 and the second photovoltaic panel 302, and the other end of the second conductor is electrically connected to the ribbon cable 403.

[0031] A vehicle-mounted wind-solar hybrid UAV 6 field operation power supply system also includes a tarpaulin 7. A roller 8 is installed on the top of the side wall of the vehicle 1. One end of the tarpaulin 7 is installed on the roller 8. The roller 8 rotates to extend and retract the tarpaulin 7.

[0032] The system's operation process is divided into transportation mode and operation mode: In the transportation state, all core components of the system are housed according to the principle of "minimizing space and maximizing protection" to meet the vehicle's driving stability requirements: The openable photovoltaic power generation mechanism 3 mounted on the vehicle 1 consists of a first photovoltaic panel 301 and a second photovoltaic panel 302. During transportation, it is folded to fit the top outline of the vehicle 1's carriage through the hinge shaft 303 to avoid occupying the carriage space. When temporarily parked, it can be unfolded into a seamless splicing plane with the help of gears 304 and racks 305 to receive sunlight vertically, achieving a good balance between space utilization and power generation efficiency.

[0033] When in the retracted and non-generating state, the wind power generation mechanism 2 is retracted under the photovoltaic power generation mechanism 3 by telescopic components and double-locked with fixed buckles. It is also equipped with hydraulic telescopic components to achieve state adjustment: in the retracted state, the hydraulic rod 208 is retracted to the shortest length, and the generator body 204 is completely inside the tarpaulin 7, which is suitable for transportation in bad weather such as rain and sandstorms, and avoids moisture and sandstorms from corroding the core components. When switching to working mode, the hydraulic rod 208 extends to the working length, and the generator body 204 rises above the tarpaulin 7. At this time, the tarpaulin 7 automatically retracts to the bottom of the photovoltaic power generation mechanism 3 through the bearing slide rails on both sides and the roller 8, which is suitable for operation in a wide area without obstruction, and captures wind energy to the maximum extent while ensuring the stability of the equipment. In addition, the drone 6 is fixed on the mounting frame 503 inside the vehicle compartment. The buffer rubber pad 502 absorbs the impact of bumps and prevents the fuselage from deforming. The first battery pack 401 and the second battery pack 402 are placed inside the sealed battery storage compartment 404. The energy storage battery pack wiring 403 is arranged in a standardized manner. The overall structure is compact and fully protected.

[0034] After the vehicle stops and confirms that the work site is "flat and free of tall obstructions", the system switches to the working state. The core components work together according to the "energy capture-conversion-storage-application" process: During the component deployment stage, with the help of the matching gear 304 and rack 305, the second photovoltaic panel 302 can be dynamically adjusted according to the actual light angle on site to always maintain the optimal light-receiving area to improve the photoelectric conversion efficiency. The generator body 204 first unlocks the latch, and then is raised to a height higher than the photovoltaic power generation mechanism 3 by the hydraulic rod 208 to avoid obstruction. The blades 201 can automatically adjust the windward angle according to the effective wind speed, and automatically retract when the wind speed exceeds the standard to prevent overload damage.

[0035] In the energy conversion process, the mechanical power of the blade 201 rotation is transmitted through the main shaft 202 with built-in damping bearing. When the speed exceeds the limit, the brake 203 is automatically activated. Finally, the generator body 204 converts the mechanical energy into AC power, and then converts it into DC power through the rectifier. The DC power generated by wind power is transmitted to the first battery pack 401 and the second battery pack 402 through the first conductor 205 and the ribbon cable 403. The DC power generated by photovoltaic power is transmitted to the first battery pack 401 and the second battery pack 402 through the second conductor and the ribbon cable 403. When the power is sufficient, the system automatically avoids overcharging. When the power of the drone 6 is insufficient, multiple drones can be charged at the same time through the charging port 504 to ensure continuous operation.

[0036] On sunny days, solar power is the primary source of power generation; on cloudy or windy days, wind power is the primary source of power generation; and on overcast days, both power generation and wind power work together to ensure that the first battery pack 401 and the second battery pack 402 are within a safe power range, thus ensuring uninterrupted operation of the UAV 6.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
