DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments will be described clearly and completely below with reference to the drawings of the embodiments of the present application, and similar component reference numbers in the drawings represent similar components. Obviously, the following described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] It should be understood that when used in the specification and the appended claims, the terms "comprise" and "include" indicate the presence of described features, integers, steps, operations, elements, and / or components, but do not exclude one or more other features, integers, steps, operations, elements, components, and / or sets thereof.

[0021] It should also be understood that the terminology used in this specification of embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of the invention. As used in this specification of embodiments of the invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0022] See Figures 1-6 This invention provides a modular portable surface rescue drone. The modular portable surface rescue drone includes a head rotor module 1 and at least one tail rotor module 2; both the head rotor module 1 and the tail rotor module 2 are equipped with a power module; the head rotor module 1 is equipped with buoyancy arms 4, the number of which is equal to the number of the tail rotor modules 2, and the buoyancy arms 4 are detachably connected to the tail rotor modules 2; when the tail rotor modules 2 are mounted on the buoyancy arms 4, all power modules are electrically connected. Specific descriptions of each component are as follows: The head rotor module 1 is the core main module of the UAV, integrating basic functions such as buoyancy support, power drive, and control coordination. It serves as the carrier connecting to the tail rotor module 2. The tail rotor module 2 provides auxiliary flight power for the UAV and can also carry functional components such as the underwater thruster 21, forming a stable rotor aerodynamic layout in conjunction with the head rotor module 1. The power module provides the power source for the UAV's flight and is the core component enabling the UAV to fly in the air. It is located on both the head rotor module 1 and the tail rotor module 2. The buoyancy arms 4 extend from the head rotor module 1, providing both buoyancy support and serving as the connecting carrier for the tail rotor module 2. Their number corresponds one-to-one with the tail rotor module 2.

[0023] In a specific embodiment, a nose rotor module 1 and two tail rotor modules 2 are provided. Two buoyancy arms 4 extend from the nose rotor module 1. Each tail rotor module 2 is detachably connected to its corresponding buoyancy arm 4 via a latch 44 and a slot 43. Both the nose rotor module 1 and the tail rotor module 2 are equipped with a power module consisting of a waterproof motor 31 and a propeller 32. When the tail rotor module 2 is installed in place, the aviation connectors between the modules automatically connect, and the circuits of all power modules are connected, and the control module of the nose rotor module 1 coordinates and drives them.

[0024] In one embodiment, the buoyancy arm 4 and the rotor buoyancy ring module are integrally molded from the same buoyancy material, such as closed-cell foam, EPP, or polymer buoyancy material. In actual production, injection molding is used to mold the buoyancy arm 4 and the rotor buoyancy ring module in one piece, eliminating the need for subsequent splicing. This ensures the integrity and sealing of the structure while reducing the complexity of the production process. The integral molding design eliminates seams at the connection between the buoyancy arm 4 and the rotor buoyancy ring module, improving buoyancy performance and impact resistance, while reducing water resistance, making the UAV navigate more smoothly on the water surface.

[0025] In other embodiments, the number of tail rotor modules 2 can be adjusted according to the needs of the rescue scenario. For example, three tail rotor modules 2 can be set, with three buoyancy arms 4 extending from the head rotor module 1 to form a quadcopter aerodynamic layout, further improving the flight stability and payload capacity of the UAV. The power module can also use a variable frequency motor 31 paired with a folding propeller 32, which can further reduce the module's storage volume while ensuring power output.

[0026] This drone breaks through the design limitations of traditional integrated drones, enabling the disassembly and storage of the equipment and greatly improving portability; the one-to-one connection between the buoyancy arm 4 and the tail rotor module 2 ensures the symmetry and stability of the rotor layout; the unified electrical conduction design of the power module ensures that the drone can be quickly put into use after assembly, meeting the time-sensitive needs of rescue sites.

[0027] See also Figures 1-6 In this embodiment, there are two tail rotor modules 2. The head rotor module 1 is provided with an upper buoyancy ring 11, a lower buoyancy ring 12 and a bearing 13. The upper buoyancy ring 11 is rotatably connected to the lower buoyancy ring 12 through the bearing 13. The upper buoyancy ring 11 and the lower buoyancy ring 12 are respectively provided with buoyancy arms 4.

[0028] The upper buoyancy ring 11 and the lower buoyancy ring 12 constitute the double-layer buoyancy ring structure of the head rotor module 1, providing buoyancy support for the UAV on the water surface, and also serving as the mounting carrier for the buoyancy arms 4, control components, etc. The bearing 13 enables the relative rotation of the upper buoyancy ring 11 and the lower buoyancy ring 12, and is the core component for the foldable two buoyancy arms 4 of the head rotor module 1.

[0029] In a specific embodiment, the tail rotor module 2 is configured to have two components. The head rotor module 1 includes an upper buoyancy ring 11, a lower buoyancy ring 12, and a rotary bearing 13. The upper buoyancy ring 11 is rotatably connected to the lower buoyancy ring 12 via the rotary bearing 13. Both the upper buoyancy ring 11 and the lower buoyancy ring 12 extend outwards as a single buoyancy arm 4, and the two buoyancy arms 4 are symmetrically distributed. When storage is required, the upper buoyancy ring 11 can be rotated and folded relative to the lower buoyancy ring 12 around the bearing 13, causing the two buoyancy arms 4 to come together, significantly reducing the storage volume of the head rotor module 1.

[0030] In some other embodiments, an angle limiter is added to the bearing 13 to limit the rotation angle between the upper buoyancy ring 11 and the lower buoyancy ring 12 to the range of 0-180°. This satisfies the requirements for folding and storage while ensuring precise positioning during unfolding, thus guaranteeing consistent installation angles of the buoyancy arms 4. Simultaneously, a buffer pad is placed at the folding contact point of the upper and lower buoyancy rings 12 to reduce structural wear during folding and unfolding, extending the equipment's service life.

[0031] The foldable design of the double-layer buoyancy ring further reduces the storage volume of the head rotor module 1, improving the portability of the device; the upper and lower buoyancy rings 12 extend the structure of the buoyancy arm 4 respectively, making the connection position of the two tail rotor modules 2 more symmetrical, and together with the tri-rotor aerodynamic layout, effectively improving the flight stability of the UAV; the bearing 13 connection method enables tool-free quick folding and unfolding, which is convenient to operate and meets the needs of use at the rescue site.

[0032] Furthermore, the buoyancy arm 4 is equipped with an aviation plug, and the head rotor module 1 is electrically connected to the tail rotor module 2 through the aviation plug.

[0033] The aviation plug is located on the buoyancy arm 4 and is the core component for realizing the electrical connection between the front rotor module 1 and the tail rotor module 2. It has the characteristics of being waterproof and preventing loosening.

[0034] In a specific embodiment, a waterproof aviation plug female head 41 is provided on the inner side of the end of the buoyancy arm 4, and a matching aviation plug male head 42 is provided on the connection end of the tail rotor module 2. When the tail rotor module 2 is inserted into the slot 43 of the buoyancy arm 4 and locked in place, the aviation plug male head 42 and female head automatically connect, realizing the circuit connection between the head rotor module 1 and the tail rotor module 2, and ensuring the signal and power transmission of the power module and other electrical components.

[0035] In other embodiments, a waterproof aviation connector with a locking structure is used. After the connectors are connected, the male and female connectors are secured by rotating the locking sleeve, preventing the connectors from becoming loose due to vibration or water flow impact during drone flight or water surface navigation. Simultaneously, a waterproof sealing ring is added to the aviation connector to further enhance its waterproof performance and adapt to complex aquatic rescue environments.

[0036] The design of the aviation plug enables rapid electrical connection between modules, eliminating the need for manual wiring and improving the assembly efficiency of the drone; the selection of waterproof aviation plugs ensures the reliability of electrical connections when the drone operates on water, avoiding short circuit failures caused by water ingress; the linkage design of the plug and mechanical connection structure allows the mechanical connection and electrical connection to be completed simultaneously, simplifying the operation process.

[0037] Furthermore, the buoyancy arm 4 is also provided with a slot 43, and the tail rotor module 2 is provided with a buckle 44 that cooperates with the slot 43. The buoyancy arm 4 and the tail rotor module 2 are mechanically connected through the cooperation of the slot 43 and the buckle 44.

[0038] Slot 43 is provided on buoyancy arm 4 to provide positioning and installation space for tail rotor module 2. Clip 44 is provided on tail rotor module 2 and cooperates with slot 43 to achieve mechanical locking between tail rotor module 2 and buoyancy arm 4.

[0039] In a specific embodiment, a rectangular slot 43 is provided at the end of the buoyancy arm 4, and an elastic buckle 44 is provided at the connecting end of the tail rotor module 2. The buckle 44 has anti-slip protrusions. When the tail rotor module 2 is inserted into the slot 43, the buckle 44 is compressed and contracted. After it is fully inserted, the buckle 44 pops up and locks into the slot of the slot 43, thereby achieving mechanical fixation between the tail rotor module 2 and the buoyancy arm 4. When disassembling, pressing the elastic end of the buckle 44 causes it to contract, and the tail rotor module 2 can be pulled out of the slot 43.

[0040] In some other embodiments, see Figures 4-6 The slots 43 are evenly distributed at the end of the buoyancy arm 4, so that the tail rotor module 2 can be mechanically fixed to the buoyancy arm 4 after rotating around the central axis by a preset angle. Figure 5 For the tail rotor module 2 relative to Figure 4 The assembly state after rotating 90° around the central axis and inserting the buoyancy arm 4.

[0041] The combination of buckle 44 and slot 43 enables quick assembly and disassembly of mechanical connections between modules without the need for tools, making operation simple; the design of anti-slip protrusions and slots improves the firmness of the connection and prevents the tail rotor module 2 from coming loose during drone flight or water maneuvering; the addition of a guide structure further improves the accuracy and stability of module installation.

[0042] Furthermore, the buoyancy arm 4 is also provided with a battery compartment 45, and a battery 46 is provided inside the battery compartment 45. The battery 46 supplies power to the power module and electrical components.

[0043] The battery compartment 45 is located inside the buoyancy arm 4 and is used to house the battery 46. The battery 46 provides power to the drone and supplies power to components such as the power module, control module, and camera 15.

[0044] In a specific embodiment, battery compartments 45 are respectively formed inside the two buoyancy arms 4. The size of the battery compartments 45 matches the lithium battery pack, and the outer side of the battery compartments 45 is equipped with sealed battery compartment covers. The lithium battery packs are placed into the two battery compartments 45 respectively, so that the center of gravity of the UAV is distributed at the center position of the nose rotor module 1, ensuring balance and stability during flight and water navigation. The battery 46 is connected to the aviation plug and control module through wires to power the entire UAV system.

[0045] In other embodiments, heat dissipation fins are installed inside the battery compartment 45, working in conjunction with the heat dissipation structure of the battery 46 to improve the heat dissipation efficiency of the battery 46 and prevent the battery 46 from overheating and affecting its performance and safety under high load. Simultaneously, a power indicator light is installed on the battery compartment cover to display the remaining power of the battery 46 in real time, allowing rescue personnel to monitor the equipment's remaining battery life.

[0046] The design of the battery compartment 45 built into the buoyancy arm 4 makes full use of the internal space of the buoyancy arm 4 and avoids the battery 46 being exposed and damaged; the symmetrical layout of the dual battery compartments 45 ensures the balance of the drone's center of gravity and improves the stability of flight and water maneuvering; the sealed battery compartment cover effectively prevents water ingress and protects the battery 46 for safe use.

[0047] Furthermore, the head rotor module 1 is provided with a sealed chamber 14, and a control module is installed inside the sealed chamber 14. The control module is electrically connected to all power modules and is used to coordinate and control the operation of the power modules.

[0048] The sealed compartment 14 is mounted on the nose rotor module 1, providing a waterproof and dustproof installation environment for the control module. The control module is the signal processing element of the UAV, used to coordinate and control the operation of various power modules, sensors, and actuators.

[0049] In a specific embodiment, a sealed chamber 14 is installed at the rear end of the upper buoyancy ring 11 of the head rotor module 1. The sealed chamber 14 is made of waterproof material, and a control module consisting of a flight controller 51 and an image transmission module 52 is installed inside. The flight controller 51 is connected to components such as the motor 31, camera 15, obstacle avoidance module 16, and underwater thruster 21 of each power module via wires, receiving sensor signals in real time and sending control commands. The image transmission module 52 transmits the images captured by the camera 15 to the ground control terminal. The cover of the sealed chamber 14 is sealed to the chamber body by a sealing ring to prevent water ingress and damage to the internal components.

[0050] In one embodiment, the control module includes a flight controller 51 and an image transmission module 52. The flight controller 51 coordinates the operation of the waterproof motor 31, propeller 32, underwater thruster 21, camera 15, and high-intensity light. The image transmission module 52 is a core electronic component that enables real-time transmission of images and videos between the UAV and the ground control terminal. The control module also includes a data transmission module 53 and a GPS module 54. The data transmission module 53 enables bidirectional data transmission between the UAV and the ground control terminal, facilitating ground personnel to send control commands and receive UAV status information. The GPS module 54 enables precise positioning and flight path planning for the UAV, allowing it to autonomously fly to the designated rescue area. Through integrated algorithms, the flight controller 51 can automatically plan the optimal rescue path based on GPS positioning information and camera 15 images, while coordinating the operation of the underwater thruster 21 and the power module to achieve autonomous rescue operations, significantly improving the intelligence level of the rescue.

[0051] The sealed cabin 14 provides reliable protection for the control module and adapts to complex water rescue environments; the centralized arrangement of the control module facilitates unified and coordinated control of various functions of the UAV, improving the intelligence and operability of the equipment; the integration of the image transmission module 52 enables real-time transmission of images from the rescue site, facilitating accurate decision-making by ground personnel.

[0052] Furthermore, the power module includes a motor 31 and a propeller 32 that is connected to the motor 31 in a transmission manner, and the upper and lower sides of the propeller 32 are provided with protective nets 33.

[0053] Motor 31 is the power output element of the power module, providing rotational power to propeller 32. Propeller 32 is connected to motor 31 and generates lift through rotation, propelling the drone into flight. Protective nets 33 are installed on the upper and lower sides of propeller 32 to prevent propeller 32 from accidentally injuring people who fall into the water or colliding with obstacles.

[0054] In a specific embodiment, the power module uses a waterproof motor 31 connected to a three-bladed propeller 32. The waterproof motor 31 is fixed on motor mounts 34 of the head rotor module 1 and the tail rotor module 2. The motor mounts 34 are connected and fixed to the rotor module housing via carbon fiber support rods 35. Mesh protective nets 33 are installed on the upper and lower sides of the rotor module housing of the propeller 32. When the motor 31 drives the propeller 32 to rotate, the protective nets 33 can effectively prevent people or debris from falling into the water from contacting the propeller 32, without affecting the aerodynamic efficiency of the propeller 32.

[0055] The selection of waterproof motor 31 is adapted to the humid environment of water rescue and avoids water ingress failure of motor 31; the setting of protective net 33 eliminates the safety hazard of propeller 32 to people falling into the water, and at the same time protects propeller 32 from collision damage; the modular configuration of power module facilitates the replacement and maintenance of individual modules.

[0056] Furthermore, the top of the first rotor module 1 is equipped with a camera 15 and an obstacle avoidance module 16.

[0057] Camera 15 is used to collect video information from the rescue scene to achieve visual positioning of the person who fell into the water. Obstacle avoidance module 16 is used to detect obstacles around the drone, identify obstacles, and ensure flight safety.

[0058] In a specific embodiment, a high-definition waterproof camera 15 is installed at the center of the top of the upper buoyancy ring 11 of the head rotor module 1. An obstacle avoidance module 16 (such as a lidar obstacle avoidance sensor) is integrated next to the camera 15. The camera 15 has a built-in high-intensity light that can be turned on at night or in low-light environments. Together with the obstacle avoidance module 16, it can detect the distance and direction of obstacles in front of the drone in real time. The flight controller 51 adjusts the flight path according to the signal from the obstacle avoidance module 16. At the same time, the camera 15 transmits the captured images to the ground via the image transmission module 52, enabling all-weather search and rescue.

[0059] The integration of camera 15 and obstacle avoidance module 16 enables dual functions of search and rescue and obstacle avoidance, enhancing the drone's autonomous flight capability in complex environments. The built-in high-intensity light allows the drone to perform rescue missions at night, breaking through time constraints. The high-definition camera 15's image transmission provides intuitive on-site information for ground rescue command, improving the accuracy of rescue decisions.

[0060] Furthermore, an underwater thruster 21 is provided at the end of the tail rotor module 2.

[0061] The underwater thruster 21 is installed at the end of the tail rotor module 2 to provide power for the UAV when it is navigating on the water surface, enabling it to maneuver on the water.

[0062] In a specific embodiment, a brushless waterproof motor 31-driven underwater thruster 21 is installed below the end of each tail rotor module 2. The propeller 32 of the underwater thruster 21 is a three-bladed underwater propeller 32. When the UAV lands on the water surface, the propeller 32 of the aerial power module stops working, and the underwater thruster 21 starts. By adjusting the speed and direction of the two underwater thrusters 21, the UAV can perform forward, backward, and turning maneuvers on the water surface, accurately approaching the person who has fallen into the water.

[0063] The underwater thruster 21 compensates for the weakness of traditional rotary-wing UAVs in water maneuverability, enabling the UAV to accurately approach a person who has fallen into the water; the drive method of the brushless waterproof motor 31 ensures the power output and service life of the underwater thruster 21; the coordinated control of the two underwater thrusters 21 improves the flexibility and accuracy of the UAV's water maneuverability.

[0064] Furthermore, handles 6 are respectively provided on the outer sides of the head rotor module 1 and the tail rotor module 2.

[0065] Handles 6 are located on the outside of the front rotor module 1 and the tail rotor module 2, for people who fall into the water to grab, so that rescuers can pull the person to the drone.

[0066] In a specific embodiment, an arc-shaped handle 6 is integrally formed on the outer side of the upper buoyancy ring 11 and lower buoyancy ring 12 of the head rotor module 1, as well as on the outer side of the buoyancy rings of the two tail rotor modules 2. The surface of the handle 6 is provided with anti-slip texture. When the drone approaches a person who has fallen into the water, the person can grab the handle 6 to maintain their balance, and rescuers can use the drone to pull the person to a safe area.

[0067] In some other embodiments, the handle 6 is wrapped in soft rubber material to improve the comfort of gripping for people falling into the water, while preventing the hand from slipping off the handle 6.

[0068] The handle 6 provides a reliable grip point for people who have fallen into the water, reducing their physical exertion in the water; the anti-slip texture design improves grip stability and prevents people from slipping out of the drone; the addition of the hook expands the drone's rescue function and can be used with tools such as rescue ropes to complete rescue missions.
