[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] Embodiment one

[0023] Please refer to Figs. 1-6 The utility model provides a kind of patrol rescue unmanned aerial vehicle for lifesaving and rescue, including unmanned aerial vehicle body 1, the bottom end of unmanned aerial vehicle body 1 is installed protective piece, it can be used to protect life buoy 12, the inner cavity of protective piece is circumferentially equidistantly installed three groups of first stand 2, each group of first stand 2 is limitedly slidably connected with a group of rack 3, and each group of rack 3 can be moved by driving assembly, to prevent life buoy 12 from being separated from protective piece.

[0024] In the embodiment, protective piece can be installed to protect life buoy 12, reduce the influence of wind force, driving assembly can drive three groups of rack 3 to limit sliding along first stand 2, and can be extended to the lower side of life buoy 12, to limit life buoy 12, prevent it from being separated from the inner cavity of protective piece, compared with prior art, protective piece can protect and limit life buoy 12, so that unmanned aerial vehicle body 1 is more stable when carrying, when flying over large water area with strong wind, life buoy 12 is not easily affected by wind force, and it is not easy to cause the instability of flight attitude of unmanned aerial vehicle body 1, to reduce operation difficulty and danger.

[0025] Please refer to Figs. 1-6As shown, the drive assembly includes a first gear 4, a second column 5, a second gear 6, and a motor 7. Each set of racks 3 meshes with a set of first gears 4, and each set of first gears 4 is connected to a set of second columns 5. The second columns 5 are rotatably mounted in the inner cavity of the protective component. All three sets of first gears 4 mesh with the second gears 6. The second gears 6 are connected to the output end of the motor 7. The motor 7 is mounted in the inner cavity of the protective component. The first gear 4 consists of two sets of gear bodies. The thickness of each set of gear bodies is the same as the thickness of the second gear 6. A first limiting groove 8 is provided on one side of each set of racks 3. A limiting block 9 is integrally formed corresponding to the first limiting groove 8 in each set of first columns 2. The limiting block 9 can slide along the first limiting groove 8. The protective component includes a baffle 10 and a protective cover 11. The baffle 10 is installed at the bottom end of the UAV body 1, and the protective cover 11 is installed on the outer wall of the baffle 10. A limiting ring 13 is installed at the bottom edge of the 10. The limiting ring 13 is provided with three sets of second limiting grooves 14 corresponding to the 3.

[0026] In this embodiment, since the first gear 4 is composed of two sets of gear bodies, and the thickness of each set of gear bodies is the same as the thickness of the second gear 6, the rack 3 can slide along one side of the second gear 4 without being affected by the second gear 6. By starting the motor 4, the second gear 6 can be driven to rotate, which in turn drives the first gear 4 to rotate, causing the rack 3 meshing with it to slide along the second column 2 for limiting, so that it moves to the bottom of the lifebuoy 12 for limiting. The first limiting groove 8 is a dovetail groove, and the limiting block 9 is a dovetail block. When the rack 3 moves, the limiting block 9 will slide in the first limiting groove 8 to limit the movement. The baffle 10 and the protective cover 11 cooperate to form a protective component to protect the life ring 12. The installed limiting ring 13 can limit the life ring 12 to prevent it from being hooked by the rack 3 when it is unlocked and deployed, thus avoiding any impact on the deployment. The second limiting groove 14 does not affect the sliding of the rack 3. The rack 3 can pass through the second limiting groove 14 and move to the bottom of the life ring 12 to prevent it from detaching from the protective component.

[0027] Working principle: First, by starting the motor 4, the second gear 6 can be driven to rotate, which in turn drives the first gear 4 to rotate, causing the rack 3 meshing with it to slide along the second column 2. The rack 3 can pass through the second limiting groove 14 and move to the bottom of the life ring 12 to prevent it from detaching from the protective part. Conversely, when the rack 3 moves to the inside of the limiting ring 13, the limitation on the life ring 12 can be released, and it can be deployed. The installed limiting ring 13 can limit the life ring 12 to prevent it from being hooked by the rack 3 when it is unlocked and deployed, thus avoiding affecting the deployment.
