Description

Technical Field

[0001] This invention relates to a self-sustaining supply platform for small marine unmanned aerial vehicles (UAVs) used on islands, belonging to the field of intelligent hangars for new energy automated UAVs. Background Technology

[0002] Currently, countries around the world are actively developing drone technology. As a weapon system that perfectly combines intelligence, automation, and unmanned operation, drones will see wider applications. However, the lack of infrastructure for drone applications, such as energy supply facilities, communication and navigation facilities, and maintenance and testing facilities, urgently needs to be addressed.

[0003] In recent years, numerous solutions have been proposed to address the issue of intelligent hangars for drones. Patents CN206829740U and CN107060447A introduce intelligent hangars for drones that utilize the daily power supply system and have a backup power system; however, their portability is poor, making them unusable on my country's relatively underdeveloped island and reef environments. Patent CN116692070A introduces a hangar with an automatic centering device, but it also lacks portability and has high infrastructure requirements, making it unsuitable for the harsh environments of islands and reefs. Patent CN107905603A introduces a drone hangar with a protective cavity, solving the problem of coping with harsh environments; however, it still relies on an external charging power supply, failing to address the long-term energy supply issue and making it unsuitable for island and reef infrastructure construction.

[0004] In response to the lack of reliable drone resupply platforms on marine islands and reefs, this patent proposes a self-sustaining resupply platform for small marine drones applicable to islands. The product is highly portable and concealable, uses wave energy for self-generation, has its own battery storage system, and is equipped with an information management system. It has low requirements for marine island and reef environmental infrastructure, can be deployed over a wide range, and can achieve functions such as drone self-identification of available hangars, wireless charging, and automatic launch of drones when fully charged. It also has a long maintenance cycle. This technology can provide theoretical support for my country's marine defense construction. Summary of the Invention

In this system, the buffer pad 1 is placed at the contact point between the top of the first cylindrical generator 2 and the first buffer pad 21 on the main shaft. The first rotor assembly 3 is fixed at one end of the main shaft 5, and the 10 individual rotors are evenly spaced.

The second cylindrical generator 7 is connected to the first cylindrical generator 2 through the main shaft 5. The second rotor group 8 is fixed at the other end of the main shaft 5, ensuring that the spacing between the 10 individual rotors is the same. The second stator group 9 has 10 individual stators, which are fixed at equal intervals inside the second cylindrical generator 7. The outer diameter of the second rotor 8 is smaller than the inner diameter of the second stator group 9. The energy storage device 11 is equipped with a power output interface 12 at the upper end. The first cylindrical generator 2 is fixed above the second cylindrical generator 7, and the vertical spacing is fixed. The first cylindrical generator 2 and the second cylindrical generator 7 are fixed on the seabed around the island. The lower part of the second cylindrical generator 7 is flexibly connected to the energy storage device 11 placed on the island through the wire 10.

[0007] The supply platform module consists of a drone 13, a first charging module 14, a detection device 15, a hangar hatch 16, a first electric hinge 17, a second charging module 18, a first parking apron 19, a hangar side cover 20, a second parking apron 27, a second electric hinge 30, and a hangar 32. In this system, the hangar hatch 16 is connected to the hangar via the electric hinge 17, the first charging module 14 is placed on the first parking apron 19, the drone 13 is parked on the first charging module 14, the detection device 15 is fixed around the inner wall of the hangar 32, the second charging module 18 is located on the second parking apron 27 at the bottom of the hangar 32, and the hangar side cover 20 is connected to the bottom via the second electric hinge 30 and can be opened from the top for operation.

[0008] The wireless charging module consists of a first centering device 25, a first visual recognition tag 26, a second centering device 28, and a second visual recognition tag 31. In this system, the first centering device 25 and the first visual recognition tag 26 are integrated on the first charging module 14, and the first charging module 14 is connected to the first landing pad 19 below, so that the first charging module 14 is in the center of the landing pad. The second centering device 28 and the second visual recognition device 31 are integrated on the second charging module 18, so that the second charging module 18 is in the center of the second landing pad 27. There is a height difference between the first landing pad 19 and the second landing pad 27 to meet the entry requirements of the drone 13.

[0009] The buoy 6 is made of fiberglass; the outer shells of the first cylindrical generator 2 and the second cylindrical generator 7 are made of seawater corrosion-resistant steel and coated with polyurethane anti-corrosion paint; the connection between the first cylindrical generator 2, the second cylindrical generator 7 and the main shaft is sealed with an "O" ring; the first stator group 4 and the second stator group 9 inside the first cylindrical generator 2 and the second cylindrical generator 7 are excitation windings made of wire; the first mover group 3 and the second mover group 8 inside the first cylindrical generator 2 and the second cylindrical generator 7 are both made of titanium iron boron, and the 10 movers are separated by non-magnetic materials.

[0010] The first charging module 14 and the second charging module 18, as well as the charging modules of both UAVs 13, all use rectangular coupling coils. The specific parameters used in the coupling experiment are: coil length 160mm, coil turns 8, coil material 500 strands of Litz wire with a cross-sectional area of ​​3 square millimeters, and system transmission frequency 60kHz. Lightweight coupling coils are installed on the charging parts of UAVs 13, which can work with the first charging module 14 and the second charging module 18 for efficient charging.

[0011] The first charging module 14 is connected to the first landing pad 19 and fixed to the housing by welding. The second charging module 18 is connected to the second landing pad 27 and fixed to the hangar side cover 20 of the housing by sliding rails. The hangar 32 controls the opening and closing of the hangar hatch 16 and the hangar side cover 20 through an intelligent system. The supply platform module can intelligently detect the approach of the adapted UAV 13 and realize the automatic opening and closing of the hangar hatch 16, the hangar side cover 20 and the sliding out of the second landing pad 27. The supply platform module can intelligently guide the UAV 13 to land on the first landing pad 19 or the second landing pad 27 respectively according to the storage status and power of the UAV 13 in the hangar.

[0012] The receiver integrated into the UAV 13 consists of one or more coils that induct with the coil of the transmitter.

[0013] When the UAV 13 is not performing a mission and is in combat readiness, the hangar hatch 16 and the hangar side cover 20 of the UAV 13 are closed to prevent debris from entering and affecting the charging and resupply of the UAV 13. The energy storage device 11 stores electrical energy in the battery and does not perform voltage boosting operation for the time being. At the same time, the information network control center will be ready to receive instructions to carry out mission operations at any time. The automated device in the hangar is on standby. After receiving the mission instruction, it will quickly open the hangar hatch 16 and the hangar side cover 20 to allow the UAV 13 to take off.

[0014] When UAV 13 is patrolling, the platform information control center will act as an information relay station, using satellite encryption to forward the information detected by UAV 13 to the control center; in addition, the platform's automated equipment will perform self-checks on the charging platform and report the self-check results to the control center. UAV 13 will form a swarm to cooperate in completing the mission, while conducting situational awareness and environmental detection in the relevant sea area.

[0015] When the drone 13 returns to resupply after completing its mission, the platform automatically matches the most suitable hangar for each drone 13. The top of the resupply platform is designed with a hangar hatch 16, which can automatically sense the approach of the drone 13. When the drone 13 approaches the resupply platform, the sensor hatch will detect the signal of the drone 13 and trigger an operation. The hangar hatch 16 and the hangar side hatch 20 will open quickly. The first charging module 14 and the second charging module 18 integrate a first centering device 25 and a second centering device 28, which are used to guide the drone 13 to accurately dock on the resupply platform. The first centering device 25 and the second centering device 28 can use visual markers, infrared, or other methods to guide the drone 13 to dock accurately on the resupply platform. The positioning technology helps the drone 13 align and dock in the correct position. After the drone 13 lands on the first charging module 14 and the second charging module 18, it will automatically close the hangar hatch 16 and the hangar side cover 20. Then, the detection device will detect the drone 13. The first charging module 14 and the second charging module 18 are respectively equipped with a first visual recognition tag 26 and a second visual recognition tag 31 for the drone 13 to identify and locate. These tags can be QR codes, barcodes, identifiers or other forms of visual markings so that the drone 13 can accurately identify the identity of the resupply platform. After confirmation, the platform will monitor the battery status of the drone 13.

[0016] Based on the battery's needs and charging status, the energy storage device 11 will automatically adjust the charging current to charge the drone 13, ensuring that the drone 13 can be recharged efficiently and safely. The first charging module 14 and the second charging module 18 each contain an electromagnetic field transmitter. The electromagnetic field transmitter generates an electromagnetic field to transmit energy. The drone 13 is equipped with an electromagnetic field receiver to receive the electromagnetic field energy generated by the transmitter.

[0017] The platform is powered by ocean wave energy; it combines an ocean energy power generation system with a UAV resupply platform, making it an integrated unmanned platform; based on the stable wave energy resources in the waters near the islands and reefs, the first cylindrical generator 2 and the second cylindrical generator 7 are connected by a main shaft 5, which can increase power generation in a small space and improve concealment.

[0018] When the energy flow density in the sea area is high, the energy storage device 11 stores excess energy. When the energy flow density is low and the power generation is insufficient to supply the platform, the energy storage device will release the stored electrical energy to ensure the platform operates normally.

[0019] The energy storage device 11 integrates a power management system, which allocates power according to different power needs. By detecting the remaining power of each drone 13, it adjusts the charging power of each drone 13 to ensure that each drone 13 can carry out swarm operations in a timely manner.

[0026] A self-sustaining resupply platform for small marine drones used on islands consists of three parts: an energy harvesting and storage module, a resupply platform module, and a wireless charging module. These three parts can work independently or in combination.

[0027] When the UAV 13 is not performing a mission and is in combat readiness, the hangar hatch 16 and the hangar side cover 20 of the UAV 13 are closed to prevent debris from entering and affecting the charging and resupply of the UAV 13. The energy storage device 11 stores electrical energy in the battery and does not perform voltage boosting operation for the time being. At the same time, the information network control center will be ready to receive instructions to carry out mission operations at any time. The automated device in the hangar is on standby. After receiving the mission instruction, it will quickly open the hangar hatch 16 and the hangar side cover 20 to allow the UAV 13 to take off.

[0028] When UAV 13 is patrolling, the platform information control center will act as an information relay station, using satellite encryption to forward the information detected by UAV 13 to the control center; in addition, the platform's automated equipment will perform self-checks on the charging platform and report the self-check results to the control center. UAV 13 will form a swarm to cooperate in completing the mission, while conducting situational awareness and environmental detection in the relevant sea area.

[0029] When the drone 13 returns to resupply after completing its mission, the platform automatically matches the most suitable hangar for each drone 13. The top of the resupply platform is designed with a hangar hatch 16, which can automatically sense the approach of the drone 13. When the drone 13 approaches the resupply platform, the sensor hatch will detect the signal of the drone 13 and trigger an operation. The hangar hatch 16 and the hangar side hatch 20 will open quickly. The first charging module 14 and the second charging module 18 integrate a first centering device 25 and a second centering device 28, which are used to guide the drone 13 to accurately dock on the resupply platform. The first centering device 25 and the second centering device 28 can use visual markers, infrared, or other methods to guide the drone 13 to dock accurately on the resupply platform. The positioning technology helps the drone 13 align and dock in the correct location. After landing on the first charging module 14 and the second charging module 18, the drone 13 will automatically close the hangar hatch 16 and the hangar side cover 20. Subsequently, the detection device will detect the drone 13. The first charging module 14 and the second charging module 18 are respectively equipped with a first visual recognition tag 26 and a second visual recognition tag 31 for the drone 13 to identify and locate. These tags can be QR codes, barcodes, identifiers, or other forms of visual markings so that the drone 13 can accurately identify the identity of the resupply platform. After confirmation, the platform will monitor the battery status of the drone 13. According to the battery's needs and charging status, the energy storage device 11 will automatically adjust the charging current to charge the drone 13, ensuring that the drone 13 is recharged efficiently and safely.

[0030] The first charging module 14 and the second charging module 18 each contain an electromagnetic field transmitter. The electromagnetic field generates an electromagnetic field to transfer energy. The drone 13 is equipped with an electromagnetic field receiver to receive the electromagnetic field energy generated by the transmitter. The receiver also consists of one or more coils that induct with the transmitter's coils. When the transmitter and receiver coils are close together, the electromagnetic field between them induces a current, thereby achieving energy transfer. By adjusting the current and frequency of the transmitter, the efficiency and speed of energy transfer can be controlled, and the system can also provide charging status feedback.

[0031] When no drones are performing charging tasks, the self-sustaining platform will perform self-checks and maintenance. During periods of inactivity, the platform will enter an automatic low-power repair mode, automatically disabling some functions to reduce component usage and extend component lifespan. For simple mechanical parts malfunctioning, the self-sustaining platform can repair them automatically. For problems the platform cannot resolve, it will immediately send relevant parameter information to the central control platform and issue warnings and alarms to remind maintenance personnel to address the issues promptly, ensuring the platform's normal operation.

[0032] This platform is powered by ocean wave energy. It combines an ocean energy power generation system with a UAV resupply platform, making it an integrated unmanned platform. Based on the stable wave energy resources in the waters near the islands and reefs, the first cylindrical generator 2 and the second cylindrical generator 7 are connected by a main shaft 5, which can increase power generation in a small space and improve concealment. When the energy flow density in the sea area is high, the energy storage device 11 stores excess energy. When the energy flow density is low and the power generation is insufficient to supply the platform, the energy storage device will release the stored electricity to ensure the platform's normal operation. The energy storage device 11 integrates a power management system, which allocates power according to different power needs. By detecting the remaining power of each UAV 13, it adjusts the charging power of each UAV 13 to ensure that each UAV 13 can carry out swarm operations in a timely manner.
