Abstract
Description
Technical Field
[0001] This utility model relates to the field of drone lifebuoy technology, and in particular to drone lifebuoy with a propulsion device. Background Technology
[0002] The drone lifebuoy is an innovative product that combines drone technology with rescue equipment. It primarily utilizes the flight capabilities of drones to quickly transport a lifebuoy to the vicinity of a person who has fallen into the water, buying valuable time for rescue. The principle is that a drone carrying the lifebuoy flies to the target location and then releases it onto the water's surface, allowing the person in the water to grab it and await further rescue.
[0003] However, in the current technology, the drone lifebuoy is easily affected by airflow during the process of landing on the water, causing it to land far away from the person in the water. After landing on the water, it is also easily affected by the water flow, causing the drone lifebuoy to be constantly moving. This makes it impossible for the person in the water to quickly grab the drone lifebuoy, all of which directly affect the rescue efficiency. Utility Model Content
[0004] This utility model mainly provides a drone rescue ring with a propulsion device that can improve rescue efficiency and prevent drowning victims from being unable to quickly grab the drone rescue ring.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drone lifebuoy with a propulsion device, comprising a drone lifebuoy body, propulsion components symmetrically fixedly installed on both sides of the drone lifebuoy body, the propulsion components comprising a positioning rod, a connecting frame, a protective ring, and a second propeller, the connecting frame being fixedly installed on both sides of the drone lifebuoy body, the positioning rod being fixedly connected to the other end of the connecting frame, an AC motor being fixedly installed at the bottom of the positioning rod, the output end of the AC motor being fixedly connected to the second propeller, the second propeller being installed inside the protective ring, and the second propeller being arranged in a horizontal state.
[0006] Preferably, a reinforcing rod is fixedly installed on the wall of the positioning rod, and the other end of the reinforcing rod is fixedly connected to the edge of the protective ring.
[0007] Preferably, a second solar panel is fixedly installed on the top of the connecting frame.
[0008] Preferably, a first propeller is fixedly installed at each of the four corners of the main body of the drone lifebuoy, and the first propeller is arranged in a vertical position.
[0009] Preferably, a first solar panel is fixedly installed on the upper surface of the main body of the drone lifebuoy, and a handle is fixedly installed on one side of the main body of the drone lifebuoy.
[0010] Preferably, a hollow shell is fixedly installed on the top edge of the main body of the drone lifebuoy, and a lithium battery is installed inside the hollow shell.
[0011] Preferably, a lighting lamp is fixedly installed on one side of the hollow shell, and the terminals of the lithium battery and the lighting lamp are movably connected.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] 1. In this utility model, by adding a propulsion component to the main body of the drone lifebuoy, when the main body of the drone lifebuoy floats on the water surface, the propulsion component will be completely submerged in the water. At this time, the AC motor drives the second propeller to move the entire drone lifebuoy on the water surface. Even if the landing point is deviated, it can quickly move to the vicinity of the person in the water, which is more helpful to the rescued person. It also enables the main body of the drone lifebuoy to maintain a relatively stable state in the turbulent water. After the person in the water grabs the main body of the drone lifebuoy, it can also be taken to a safe area, further increasing the probability of successful rescue.
[0014] 2. In this utility model, multiple solar panels are installed on the main body of the drone lifebuoy to provide power to the main body of the drone lifebuoy, so as to extend the flight time of the main body of the drone lifebuoy and buy more time for rescue. Attached Figure Description

Each propulsion component 6 includes a positioning rod 61, a connecting frame 64, a protective ring 63, and a second propeller 66. The connecting frame 64 is fixedly installed on both sides of the drone lifebuoy body 1, and the positioning rod 61 is fixedly connected to the other end of the connecting frame 64. An AC motor 62 is fixedly installed at the bottom of the positioning rod 61, and the output end of the AC motor 62 is fixedly connected to the second propeller 66. The second propeller 66 is installed inside the protective ring 63 and is arranged horizontally. The propulsion components 6 are fixedly arranged on both sides of the drone lifebuoy body 1. In actual use, the drone lifebuoy body 1 flies to the water... Once the person is near the drone, the main body 1 of the drone lifebuoy floats on the water. If it is far from the person, the AC motor 62 drives the second propeller 66. The second propeller 66 stirs the water to move the entire main body 1 of the drone lifebuoy, bringing it closer to the person. The person can then grab the main body 1, which will quickly take them to a safe area to await rescue. The connecting frame 64 in the propulsion assembly 6 is fixedly installed on the main body 1 of the drone lifebuoy, and the positioning rod 61 is set to an inclined position to ensure that the protective ring 63 does not come into contact with the main body 1. At the same time, the second propeller 66 is built into the protective ring 63 to prevent the person from coming into contact with the second propeller 66, thus protecting the person.
[0023] according to Figure 2 and Figure 4 As shown, a reinforcing rod 67 is fixedly installed on the wall of the positioning rod 61. The other end of the reinforcing rod 67 is fixedly connected to the edge of the protective ring 63. The reinforcing rod 67 is used to improve the structural strength of the protective ring 63, ensuring that the protective ring 63 can withstand different water flow conditions and also allows the protective ring 63 to withstand the impact of the human body.
[0024] according to Figure 2 and Figure 4 As shown, a second solar panel 65 is fixedly installed on the top of the connecting frame 64. The second solar panel 65 is used to utilize solar energy.
[0025] according to Figure 1 and Figure 2 As shown, a first propeller 3 is fixedly installed at each of the four corners of the drone lifebuoy body 1. The first propeller 3 is arranged in a vertical position and is used to drive the drone lifebuoy body 1 to fly.
[0026] according to Figure 1 As shown, a first solar panel 4 is fixedly installed on the upper surface of the drone lifebuoy body 1, and a handle 2 is fixedly installed on one side of the drone lifebuoy body 1.

[0027] according to Figure 1 , Figure 2 and Figure 3 As shown, a hollow shell 5 is fixedly installed on the top edge of the main body 1 of the drone lifebuoy. A lithium battery is installed inside the hollow shell 5. The hollow shell 5 is used to protect the lithium battery and prevent the lithium battery from coming into contact with water.
[0028] according to Figure 1 , Figure 2 and Figure 3 As shown, a lighting lamp 7 is fixedly installed on one side of the hollow shell 5. The terminals of the lithium battery are movably connected to the terminals of the lighting lamp 7. The power of the lighting lamp 7 is provided by the lithium battery, which can provide auxiliary lighting at night.
[0029] The usage and working principle of this device are as follows: In actual use, the first propeller 3 drives the entire drone lifebuoy body 1 to fly to the vicinity of the person who has fallen into the water. Then the first propeller 3 stops operating, allowing the drone lifebuoy body 1 to land on the water surface.
