[0034] Detailed description structure:

[0035] The main part of the drone is a quad-rotor drone device 1, on the lower side of which a water rescue lifebuoy delivery mechanism 2 is fixed.

[0036] The core component of the water rescue lifebuoy delivery mechanism 2 is the top connecting plate 3. At the lower edge of the top connecting plate 3, a servo motor 4 and two bearing seats 5 are arranged in an equilateral triangle and are firmly fixed. The two bearing seats 5 are respectively mounted with transmission shafts 6, which extend downward.

[0037] The output shaft of the servo motor 4 extends downward, and the first sprocket 7 is fixedly mounted at its end. Similarly, the second sprocket 8 is also fixed at the end of the transmission shaft 6, and the first sprocket 7 and the two second sprockets 8 are connected to each other through a chain 9.

[0038] The active arc placement rod 10 is firmly fixed at the edge of the first sprocket 7. When the life buoy is held by the active arc placement rod 10, the inner side of the life buoy can be just in the arc opening thereof, and the opening faces outwards, and the fixed connection position of the active arc placement rod 10 and the first sprocket 7 is away from the middle of the top connecting plate 3.

[0039] The auxiliary arc placement rod 11 is also fixed at the edge of the second sprocket 8. When the life buoy is held by the auxiliary arc placement rod 11, the situation is similar to that when it is held by the active arc placement rod 10. The inner side of the life buoy is located in the arc opening, the opening faces outward, and the fixed connection between the auxiliary arc placement rod 11 and the second sprocket 8 is also far away from the middle of the top connecting plate 3.

[0040] A battery 12 and a controller 13 are fixedly arranged in the middle of the lower side of the top connecting plate 3. The battery 12 is a lithium battery, and the controller 13 is electrically connected to the battery 12 and the servo motor 4 to realize control and power supply.

[0041] Detailed description of usage:

[0042] First, place the lifebuoy flat on the corresponding position of the device. Make sure that the lifebuoy is accurately positioned so that it can fully contact the active arc placement rod 10 and the auxiliary arc placement rod 11. During the placement process, pay attention to the inner side of the lifebuoy can just fit into the arc opening of the active arc placement rod 10 and the auxiliary arc placement rod 11. Due to the outward opening design, the lifebuoy can be stably supported and will not slip easily. At the same time, it is noted that the fixed connection between the active arc placement rod 10 and the first sprocket 7 and the fixed connection between the auxiliary arc placement rod 11 and the second sprocket 8 are both away from the middle of the top connecting plate 3. This positional relationship helps to better fix the lifebuoy and ensure that the lifebuoy can remain stable during subsequent flights and operations.

[0043] Detailed instructions for releasing the lifebuoy:

[0044] When faced with the situation of needing to release the lifebuoy, the relevant staff first needs to operate the external terminal device, establish a connection with the controller 13 through a specific signal or instruction and realize control. When the four-rotor drone device 1 arrives at the specified position in flight, the staff uses the external terminal device to send instructions to the controller 13 again. After receiving the instruction, the controller 13 immediately starts and controls the servo motor 4 to start rotating. The rotation of the servo motor 4 will drive the first sprocket 7 fixed at its end to rotate. Since a transmission relationship is formed between the first sprocket 7, the chain 9 and the two second sprockets 8, the rotation of the first sprocket 7 will drive the two second sprockets 8 to rotate synchronously through the chain 9. As the sprockets rotate, the active arc-shaped placement rod body 10 and the auxiliary arc-shaped placement rod body 11 fixed on the edge of the sprocket will also rotate accordingly. During the rotation process, the lifebuoy will gradually break away from the arc opening of the active arc-shaped placement rod body 10 and the auxiliary arc-shaped placement rod body 11. At the same time, the active arc-shaped placement rod 10 and the auxiliary arc-shaped placement rod 11 will move toward the middle direction close to the top connecting plate 3, providing more space and convenience for the smooth release of the lifebuoy, and finally achieving accurate placement of the lifebuoy.

[0045] Describe the advantages in detail:

[0046] Easy to fix the lifebuoy:

[0047] The device is designed with an active arc-shaped placement rod 10 and an auxiliary arc-shaped placement rod 11. The special arc-shaped opening and position design allow the inner side of the lifebuoy to be easily embedded, and the structure with the opening facing outwards makes it difficult for the lifebuoy to fall off or shift when fixed. This design makes the fixing process of the lifebuoy simple, fast and stable, and can ensure that the lifebuoy is firmly placed on the device whether in transportation or flight, so as to be fully prepared for subsequent rescue operations.

[0048] Easy to release the lifebuoy:

[0049] When the lifebuoy needs to be released, the relevant staff controls the controller 13 through the external terminal device, and then starts the rotation of the servo motor 4. This transmission mechanism drives the rotation of the sprocket and the arc-shaped placement rod body, so that the lifebuoy can quickly break away from the arc-shaped opening, and achieve accurate and rapid release. At the same time, the arc-shaped placement rod body is close to the middle of the top connecting plate 3, creating more favorable conditions for the smooth release of the lifebuoy. The entire release process has a high degree of automation, is easy to operate, and has a quick response, which can provide timely rescue for the drowning person at a critical moment.

[0050] Rapid and accurate release of lifebuoys provides timely and effective rescue tools for drowning people, increasing their chances of being rescued:

[0051] With the efficient flight capability of the quad-rotor drone device 1, it is possible to quickly reach the designated rescue location. With the precise control and transmission system, it is ensured that the lifebuoy is dropped at the right time and place. This fast and accurate drop capability can provide key rescue tools when the drowning person needs them most, greatly shortening the time the drowning person has to wait for rescue, significantly increasing their chances of being rescued, and gaining precious time to save lives.

[0052] It saves rescue preparation time and can complete the deployment of lifebuoys in a short time, thus buying more precious time for rescue:

[0053] The device is optimized in structure and operation. The whole process from fixing the lifebuoy to releasing the lifebuoy is simple and efficient. No cumbersome preparation steps are required. Once a rescue command is received, it can respond quickly and complete the release of the lifebuoy in a short time. This rapid response capability effectively saves rescue preparation time, wins more critical time for rescue operations, and thus improves the efficiency and success rate of rescue.

[0054] Controlled by external terminal equipment, convenient operation and easy to master:

[0055] By connecting the external terminal device to the controller 13, the staff can operate remotely in a safe location. This control method is not only convenient and flexible, but also reduces the risk of operators directly contacting dangerous environments. Its operation interface and instruction design are concise and clear, and can be mastered after simple training, so that operations can be performed quickly and accurately in emergency rescue scenarios to ensure the smooth progress of rescue operations.

[0056] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
