The outer sleeve of the lifebuoy fixing sleeve 2 is provided with multiple groups of lifebuoy bodies 3.

[0026] In this embodiment: the existing device {publication (announcement) number}: CN205239917U discloses a drone water rescue device, a drone water surface automatic rescue device proposed in this patent in this application document, the limiting mechanism 201 in this application document adopts the same technical means in this prior art, and this technical means is not repeated here one by one. This application makes further improvements on this existing subject, and please refer to the disclosed technology below for details; in order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "when the above design is used, although one drone flight can rescue multiple targets and improve the use effect of the equipment, but because the lifebuoy is affected by the water flow and wind when it falls to the water surface, it is easy to cause the lifebuoy to deviate, making it difficult for the person who falls into the water to grab the lifebuoy, so that he cannot get better rescue, which reduces the use effect of the equipment". In terms of use, this problem is obviously a real problem that exists and is difficult to solve. In view of this, in order to solve this technical problem, a connecting component 4 and a buffer component 5 are added to the application document, and the power equipment involved in this product is powered by an external power supply.

[0027] It should be noted that the accessories used by the limiting mechanism 201 have been disclosed by publication number CN205239917U, and its use effect can refer to publication number CN205239917U (that is, "lifebuoy baffle, cantilever baffle A, motor stator, electronic rotor, cantilever, guide wheel, cantilever baffle B, guide rail, fixed baffle, return spring, guide rod and bottom plate components" disclosed in this prior art).

[0028] More specifically:

[0029] like Figure 1-Figure 4 As shown:

[0032] In this embodiment: when the unmanned aerial vehicle automatic water rescue device needs to rescue people in the water, the unmanned aerial vehicle body 1 is then moved to the rescue area, and then the life buoy body 3 on the life buoy fixing sleeve 2 is released by the limiting mechanism 201, so that the life buoy body 3 is released. When the life buoy body 3 is released, the electric push rod 402 is started, and the moving rod 407 is driven to move by the start of the electric push rod 402, so that the moving rod 407 releases the squeezing of the winding wheel 405.

At this time, the connection between the rope 406 and the drone body 1 is released, so as to prevent the person who falls into the water from grabbing the lifebuoy body 3, which will cause the center of gravity of the drone body 1 to be unstable, thereby affecting the flight of the drone body 1.

[0036] Going further;

[0037] In an optional embodiment, a rubber block 408 is fixed to one end of the rope 406 , and the rubber block 408 is located between the winding wheel 405 and the rubber block 408 .

[0038] In this embodiment, the friction force of the end of the rope 406 can be increased by the rubber block 408, so that the initial fixing effect of the baffle 1 409 on the end of the rope 406 is more stable.

[0039] Going further;

[0040] In an optional embodiment, a rubber pad 413 is fixed to one end of the moving rod 407 .

[0041] In this embodiment: the moving rod 407 drives the rubber pad 413 to release the squeezing of the winding wheel 405. The rubber pad 413 can increase the friction force, improve the squeezing and fixing effect of the winding wheel 405, and avoid the rope 406 on the winding wheel 405 from becoming fluffy.

[0042] Going further;

[0043] In an optional embodiment, a protective cover 403 is disposed outside the electric push rod 402 , and the protective cover 403 is connected to the surface of the support plate 401 by bolts.

[0044] In this embodiment, the protective cover 403 on the electric push rod 402 can provide a certain protective effect on the electric push rod 402 and increase the service life of the electric push rod 402.

[0045] Further,

[0046] The UAV automatic surface rescue device has a buffer assembly 5 installed on the UAV body 1. The buffer assembly 5 includes a plurality of support rods 501 arranged in a ring shape and fixed on the surface of the UAV body 1, a base 504 slidably connected to the bottom of the support rods 501, and a fixed plate 502 fixed on the surface of the support rods 501. A spring 503 is wound around the surface of the support rod 501, and the two ends of the spring 503 are fixedly connected to the fixed plate 502 and the base 504 respectively.

[0047] In this embodiment: when the drone body 1 returns after the rescue is completed, when the drone body 1 contacts the ground through the base 504 on the support rod 501, the spring 2 503 can buffer the impact force of the drone body 1 landing, reduce the impact force, ensure that the drone body 1 is not damaged, and increase the service life of the drone body 1.

[0048] The working principle and use process of the utility model: when the unmanned aerial vehicle automatic water rescue device needs to rescue people in the water, the unmanned aerial vehicle body 1 is then moved to the rescue area, and then the life buoy body 3 on the life buoy fixing sleeve 2 is released through the limiting mechanism 201, so that the life buoy body 3 is released. When the life buoy body 3 is released, the electric push rod 402 is started, and at the same time, the protective cover 403 on the electric push rod 402 can provide a certain protection effect on the electric push rod 402, thereby improving the service life of the electric push rod 402. By starting the electric push rod 402 and driving the moving rod 407 to move, the life buoy body 3 is released. The moving rod 407 drives the rubber pad 413 to release the squeezing of the winding wheel 405. The rubber pad 413 can increase the friction force, improve the squeezing and fixing effect of the winding wheel 405, and avoid the rope 406 on the winding wheel 405 from becoming fluffy. When the squeezing of the winding wheel 405 is released, the self-gravity of the lifebuoy body 3 drives the rope 406 to move downward, and at the same time makes the winding wheel 405 rotate until the lifebuoy body 3 falls on the water surface, and then the drone body 1 drives the lifebuoy body 3 to move to the rescuer through the rope 406 until the drowning person grabs the lifebuoy body 3. When the lifebuoy body 3 is affected by the water flow and wind, When the drowning person grabs the life buoy body 3, the electric push rod 402 is started to move, and the moving rod 407 is driven to move, and the fixed rod 412 is driven to move synchronously by the moving rod 407, and the baffle 409 is pushed to move by the fixed rod 412, and the baffle 409 is compressed by the spring 411, and the rubber block 408 on the rope 406 is squeezed at this time, and the rope 406 and the rubber block 408 are squeezed at this time. The connection between the drone bodies 1 can prevent the person who falls into the water from grabbing the lifebuoy body 3, which will cause the center of gravity of the drone body 1 to be unstable and affect the flight of the drone body 1. The rubber block 408 can increase the friction force at the end of the rope 406, so that the initial fixing effect of the baffle 1 409 on the end of the rope 406 is more stable. When the drone body 1 returns after the rescue is completed, when the drone body 1 contacts the ground through the base 504 on the support rod 501, the spring 2 503 can buffer the impact force of the drone body 1 landing, reduce the impact force, ensure that the drone body 1 is not damaged, and increase the service life of the drone body 1.
