Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicles (UAVs), specifically a maritime rescue UAV. Background Technology

[0002] With its advantages of rapid response, efficient search and low cost, drones have become an important tool for maritime search and rescue. They can quickly reach the scene in complex sea conditions and bad weather. By carrying high-definition cameras, thermal imagers and positioning equipment, they can accurately locate people or ships in distress and transmit on-site information in real time. Drones can also drop life-saving equipment, food and medical supplies, buying valuable time for subsequent rescue efforts.

[0003] Currently, in the use of rescue drones, the drone is connected to a lifebuoy via a rope. The operator uses a controller to move the drone to the person in need of rescue and hand over the lifebuoy. However, there is a problem in actual operation: when the drone is flying over the sea with a long rope and lifebuoy, the operator needs to precisely control the lifebuoy suspended below the drone to accurately deliver it to the person in need of rescue due to the long rope. This results in poor operational convenience. In view of this, the inventor urgently needs to design a rescue drone with higher ease of operation to improve the speed of delivering the lifebuoy to the person in need of rescue. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a maritime rescue drone to solve the technical problems of inconvenient operation and difficulty in accurate delivery when the rescue drone is towing a long rope to deliver a lifebuoy at sea.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a maritime rescue drone, comprising a drone body, with support legs fixedly installed at the four lower corners of the drone body, and a life ring electrically detachable and connected to the lower part of the support legs via a connecting mechanism; a suspension mechanism is installed directly below the drone body, the suspension mechanism including a mounting frame, a winding frame rotatably mounted on the inner side of the mounting frame, a servo motor mounted on one side of the mounting frame, the output end of the servo motor being drively connected to the winding frame, and a rope wound around the winding frame, one end of the rope being fixedly connected to the life ring.

[0006] By adopting the above technical solutions, the connecting mechanism enables the electric controllable detachable connection between the lifebuoy and the drone, providing a foundation for rapid release. At the same time, the suspension mechanism, its servo motor, reel, and rope constitute an independent precision hoisting and deployment system, working in conjunction with or as a backup to the connecting mechanism. This dual guarantee mechanism greatly enhances the reliability of rescue operations, ensuring that the lifebuoy can be quickly deployed and that a controllable, stable, and precise suspension release can be achieved.

[0007] Furthermore, the connecting mechanism includes a support plate, which is fixedly disposed below each support leg.

[0008] By adopting the above technical solution, a stable and evenly distributed installation foundation is provided for the electromagnetic connection components, ensuring that the lifebuoy is firmly held during flight and effectively preventing the risk of shaking or falling off that may be caused by single-point connection, thereby ensuring the safety and stability of the flight platform.

[0009] Furthermore, an electromagnetic plate is installed below the support plate, and the support plate is magnetically connected to the lifebuoy through the electromagnetic plate and the magnetic plate.

[0010] By adopting the above technical solution, an electromagnetic plate is installed under the support plate and connected to the magnetic plate on the life ring by its attraction force, creating a non-contact electronic control connection solution. This electromagnetic adsorption method has the advantages of rapid response and precise control. The operator can release the life ring by instantly switching the power on and off via remote control. The whole process does not require complex mechanical moving parts, and the action is crisp and clean, which greatly improves the rescue response speed.

[0011] Furthermore, both the electromagnetic plate and the servo motor are electrically connected to the internal power supply via a remote control controller.

[0012] By adopting the above technical solution, a centralized and unified wireless control system was constructed, enabling operators to send instructions synchronously or sequentially through a single control terminal from a remote command center or rescue vessel, coordinating the electromagnetic release of the lifebuoy and the lowering of the rope, thus simplifying complex operation processes.

[0013] Furthermore, the support plate has a plate-like structure, and when the lifebuoy is not installed, the support plate serves as the base plate for supporting the main body of the drone.

[0014] By adopting the above technical solution, the plate-like structure of the support plate, when not equipped with a lifebuoy, serves as an additional support base for the main body of the drone, demonstrating the multi-functional utilization of the structural components. This significantly enhances the overall stability and low center of gravity of the drone during take-off, landing, parking, or waiting for operation, effectively preventing tilting or overturning, and protecting important equipment such as the camera mechanism under the fuselage from ground impact or scratches.

[0015] Furthermore, protective rings are fixedly installed on the inner side of the four sets of support legs. The protective rings are inflatable airbag structures or foam, and are used to make the drone float on the sea surface when the main body is not in operation.

[0016] By adopting the above technical solutions, the drone is provided with crucial water survivability, forming an effective safety redundancy. If the drone accidentally falls into the water due to sudden failure, energy depletion, or encountering severe sea conditions, the buoyancy provided by the protective ring can immediately ensure that the main body of the drone and its internal precision electronic equipment float on the sea surface, greatly increasing the possibility of successful recovery and avoiding costly asset losses.

[0017] Furthermore, several sets of propellers controlled by motors are installed on the upper part of the drone body, and a camera mechanism is installed on the lower side of the drone body.

[0018] By adopting the above technical solutions, the multi-rotor power layout provided by multiple sets of propellers endows the UAV with the ability to take off and land vertically, hover in the air, and maneuver flexibly in all directions. This enables it to respond quickly, overcome geographical limitations, and reach the rescue site rapidly. It can also maintain a stable flight attitude in windy environments, which is a prerequisite for completing precise delivery missions.

[0019] In summary, the present invention has the following main advantages:

[0020] 1. This utility model uses a connecting mechanism and a suspension mechanism. The electromagnetic plate of the connecting mechanism is combined with the magnetic plate of the lifebuoy to achieve rapid release. The servo motor of the suspension mechanism controls the rope to achieve precise hoisting and release, avoiding the problem of wind and waves interfering with traditional throwing, and ensuring that the lifebuoy is delivered to the location of the person who has fallen into the water smoothly, thereby improving the speed of drone rescue.

[0021] 2. This utility model provides floating capability in water by using the protective ring on the inner side of the support frame, thus ensuring the recyclability of the drone. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] In this embodiment:

[0029] A type of maritime rescue drone, such as Figure 1-4 As shown, the device includes a drone body 1. Support legs 4 are fixedly installed at the four lower corners of the drone body 1. A lifebuoy 5 is electrically detachable and connected to the lower part of the support legs 4 via a connecting mechanism 6. A suspension mechanism 8 is installed directly below the drone body 1. The suspension mechanism 8 includes a mounting frame 801. A winding frame 802 is rotatably mounted on the inner side of the mounting frame 801. A servo motor 803 is mounted on one side of the mounting frame 801. The output end of the servo motor 803 is connected to the winding frame 802. A rope 804 is wound around the winding frame 802, and one end of the rope 804 is fixedly connected to the lifebuoy 5. The connecting mechanism 6 enables the electronically detachable connection between the lifebuoy 5 and the drone, providing a foundation for rapid release. Meanwhile, the suspension mechanism 8, along with its servo motor 803, reel 802, and rope 804, constitutes an independent precision hoisting system that works in conjunction with or as a backup to the connecting mechanism 6. This dual-protection mechanism significantly enhances the reliability of rescue operations, ensuring that the lifebuoy 5 can be rapidly deployed and achieve controlled, stable, and precise suspension and release. This effectively avoids the potential deviation issues that may occur when directly throwing the lifebuoy in windy and wavy conditions, and significantly improves the success rate of people in the water obtaining rescue equipment.

[0030] See Figure 1 , Figure 4 The connecting mechanism 6 includes a support plate 601, which is fixedly installed below each support foot 4. This provides a stable and evenly distributed installation base for the electromagnetic connection components, ensuring that the lifebuoy 5 is firmly held during flight. This effectively prevents the risk of shaking or falling off that may be caused by a single point connection, thereby ensuring the safety and stability of the flight platform. At the same time, the distributed layout of multiple support plates 601, combined with the support foot 4 of the UAV, forms an enclosed fixing structure for the lifebuoy 5. This not only optimizes the aerodynamic layout of the UAV and reduces flight drag, but more importantly, it makes the center of gravity of the lifebuoy 5 closer to the main body of the UAV 1, further improving the handling quality and resistance to wind and wave interference of the aircraft during rescue flights.

[0031] See Figure 1 , Figure 4An electromagnetic plate 602 is installed below the support plate 601. The support plate 601 is magnetically connected to the lifebuoy 5 through the electromagnetic plate 602 and the magnetic plate 603. The electromagnetic plate 602 is installed below the support plate 601 and is connected to the lifebuoy 5 by the attraction force between it and the magnetic plate 603 on the lifebuoy 5, creating a non-contact electronic connection solution. This electromagnetic adsorption method has the advantages of rapid response and precise control. The operator can release the lifebuoy 5 by instantly switching the power on and off via remote control. The whole process does not require complex mechanical moving parts, and the action is crisp and clean, which greatly improves the rescue response speed. At the same time, the magnetic connection surface usually has good adaptability. Even if there is slight turbulence on the sea surface or slight deviation in alignment, reliable adsorption can still be guaranteed. Its structure is relatively simple, which reduces the maintenance complexity of the system and improves the working reliability under different sea conditions.

[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4 Both the electromagnetic plate 602 and the servo motor 803 are electrically connected to the internal power supply through a remote controller, forming a centralized and unified wireless control system. This allows operators to send commands synchronously or sequentially through a single control terminal from a remote command center or rescue vessel, coordinating the electromagnetic release of the lifebuoy 5 and the hoisting action of the rope 804. This simplifies complex operational processes. At the same time, the use of an internal power supply ensures the independence and reliability of the actuator's operation, freeing it from the power attenuation or signal interference issues that may arise from long-distance wired transmission. This guarantees that even when the remote control signal strength fluctuates, once the command is delivered, the actuator can still obtain full energy supply, thus accurately completing the release or retrieval operation.

[0033] See Figure 1 , Figure 4 The support plate 601 has a plate-like structure. When the lifebuoy 5 is not installed, the support plate 601 serves as the base plate supporting the main body of the drone 1. The plate-like structure of the support plate 601 serves as an additional function when the lifebuoy 5 is not installed. As the base plate supporting the main body of the drone 1, it reflects the multi-functional utilization of the structural components. It significantly enhances the overall stability and low center of gravity of the drone during take-off, landing, parking, or waiting for operation, effectively preventing tilting or tipping over. It protects important equipment such as the camera mechanism 3 under the fuselage from ground impact or scratches. At the same time, the flat plate-like structure provides a protected bottom space for the drone, which is conducive to daily maintenance and storage.

[0034] See Figure 1 , Figure 2 , Figure 3The inner sides of the four sets of support legs 4 are fixed with protective rings 7. The protective rings 7 are inflatable airbag structures or foam. The protective rings 7 are used to make the main body of the UAV 1 float on the sea surface when it is not in operation, providing the UAV with crucial water survival capability and forming an effective safety redundancy. Once the UAV accidentally falls into the water due to sudden failure, energy depletion or encountering bad sea conditions, the buoyancy provided by the protective rings 7 can immediately ensure that the main body of the UAV 1 and its internal precision electronic equipment float on the sea surface, greatly increasing the possibility of successful recovery and avoiding costly asset loss. At the same time, the use of inflatable airbags or foam materials means that this setup achieves a good balance between weight, buoyancy efficiency and reliability. The inflatable airbags can be quickly inflated through a trigger mechanism when needed, while the foam material can provide maintenance-free permanent buoyancy. Both can buffer the impact of sea waves and protect the core structure.

[0035] See Figure 1 , Figure 2 , Figure 3 Several sets of motor-controlled propellers 2 are installed on the top of the main body 1 of the drone. A camera frame 3 is installed on one side of the lower part of the main body 1 of the drone. The multi-rotor power layout provided by the multiple sets of propellers 2 gives the drone the ability to take off and land vertically, hover in the air, and maneuver flexibly in all directions. This enables it to respond quickly, overcome geographical limitations, and reach the rescue site quickly. It can also maintain a stable flight attitude in windy environments, which is a prerequisite for completing the precise delivery mission. At the same time, the configuration of the camera frame 3 provides valuable real-time visual information for remote operators, enabling them not only to search for and locate the person in the water and assess the sea conditions, but also to provide visual guidance and effect evaluation during the entire process of hoisting and dropping the lifebuoy 5. This realizes the full-process visual control from search, identification, approach to delivery.

[0036] The implementation principle of this embodiment is as follows: When the rescue mission begins, the main body of the drone 1 flies towards the target sea area under the lift provided by the propeller 2 driven by the motor. During the flight, the operator can search for and locate the distressed person through the real-time images transmitted by the camera 3 installed below it.

[0037] The drone carries the lifebuoy 5 through the connecting mechanism 6 located below its support legs 4. The core of this connecting mechanism is the electromagnetic plate 602 installed on the support plate 601, which generates a magnetic attraction with the magnetic plate 603 on the lifebuoy 5, thereby stably adsorbing and fixing the lifebuoy 5 to the bottom of the drone.

[0038] When the drone flies over the person in distress, the operator controls the electromagnetic plate 602 to de-energize it via remote control to release the magnetic attraction. At the same time, the suspension mechanism 8 located directly below the drone starts to work; the servo motor 803 inside drives the reel 802 to release the rope 804, so that the lifebuoy 5 can be lowered to the sea surface smoothly and controllably under the action of gravity, for the person in distress to grab.

[0039] To enhance the safety redundancy of the drone, a protective ring 7 is also installed on the inner side of the support legs 4. This design ensures that the drone can effectively float on the sea surface and wait for recovery in the event of an accidental fall into the water, thereby ensuring the safety of the equipment.
