[0030] Such as Figure 1 - Figure 2As shown in the figure, an unmanned aerial vehicle for a marine rescue ship includes a fuselage 1. A housing 2 and a box body 3 are respectively arranged at the bottom of the fuselage 1. The housing 2 and the box body 3 are vertically arranged front and back at the bottom of the fuselage 1. A first gear 202 is arranged on the inner wall of the housing 2, and a driving part for driving the first gear 202 to rotate is arranged on the outer wall of the housing 2. A second gear 203 is meshed and connected to the inner wall of the first gear 202. Arc plates 205 are respectively rotatably connected to the inner walls of the first gear 202 and the second gear 203. It also includes:

[0031] A reel 4 is arranged inside the box body 3, and a safety rope 8 is wound on the reel 4;

[0032] A fixing component 7 is slidably arranged inside the top of the box body 3.

[0033] In the above embodiment, when it is necessary to throw a lifebuoy 9 to the rescue personnel, the driving motor 201 is started. When the driving motor 201 works, it can drive the first gear 202 to rotate. When the first gear 202 rotates, it can drive the second gear 203 to rotate. At the same time, through the transmission shaft 204, another set of first gear 202 and second gear 203 can be driven to rotate. When the first gear 202 and the second gear 203 rotate synchronously, the two arc plates 205 connected by the connecting column can be driven to approach or move away from each other. When the two arc plates 205 move away from each other, the lifebuoy 9 placed between the two arc plates 205 can be released and then dropped near the rescue personnel. A safety rope 8 is tied to the lifebuoy 9. When the lifebuoy 9 falls, the rotating roller inside the reel 4 is driven to rotate by the servo motor arranged on the side of the reel 4, so that the safety rope 8 falls together with the lifebuoy 9. If the sea is rough, the lifebuoy 9 may not be accurately thrown to the rescued person at one time due to the wind and waves. At this time, the safety rope 8 can be retracted by rotating the servo motor, thereby driving the lifebuoy 9 to be retracted for a second throw. Another rope is tied to the lifebuoy 9 and connected to the rescue ship. After the rescued person gets the lifebuoy 9, the rescued person can be pulled onto the rescue ship through this rope. When the safety rope 8 is retracted, the electric slide rail 5 works to drive the limit ring 501 to slide reciprocally, so that the safety rope 8 can be evenly wound on the rotating roller. A guide ring 6 is arranged on the top of the box body 3, and the outer circumference of the guide ring 6 is set in an arc-shaped smooth style, so that the safety rope 8 is more smooth when being retracted and released. The guide ring 6 is fixed to the top of the box body 3 through the clamping column 701. After long-term use, the guide ring 6 will be worn and needs to be replaced. The dial 702 can be toggled to make the clamping column 701 slide out of the inner wall of the guide ring 6, and at the same time, the spring 703 is compressed. After replacing the new guide ring 6, the dial 702 is released to make the spring 703 rebound to fix the guide ring 6, and it is also convenient to replace the safety rope 8.

[0034] Such as Figure 3 - Figure 4As shown, the driving part includes a driving motor 201. The driving motor 201 is fixedly connected to the outer wall of the housing 2, and the output end of the driving motor 201 is fixedly connected to the first gear 202 for driving the first gear 202 to rotate.

[0035] In the above embodiment, when the drone flies to a suitable position and needs to drop the life buoy 9, the driving motor 201 is started. When the driving motor 201 works, it can drive the first gear 202 to rotate, and then drive the second gear 203 to rotate. When the first gear 202 and the second gear 203 rotate, the two arc plates 205 can be driven to move away from each other, releasing the life buoy 9 to fall near the person to be rescued.

[0036] As Figure 4 shown, two transmission shafts 204 are fixedly connected to the inner walls of both the first gear 202 and the second gear 203. On the other side of the inner wall of the housing 2, a set of the first gear 202 and the second gear 203 are provided. The two first gears 202 are connected by the transmission shaft 204. A connecting rod 206 is rotatably connected to the inner wall of the housing 2, and the connecting rod 206 is rotatably connected to the arc plate 205 through a rotating shaft.

[0037] In the above embodiment, when the driving motor 201 works to drive the two arc plates 205 to move away from each other, when the first gear 202 on one side rotates, it can drive the second gear 203 to rotate, and at the same time drive the first gear 202 and the second gear 203 on the other side to rotate through the transmission shaft 204. When the first gear 202 and the second gear 203 rotate synchronously, the two arc plates 205 connected by the connecting columns can move closer to or away from each other. The arc plates 205 are connected to the housing 2 through the connecting rod 206, which plays a limiting role on the arc plates 205 to prevent the arc plates 205 from flipping excessively.

[0038] As Figure 4 shown, the tail end of the arc plate 205 is set to be arc-shaped, and the surface of the arc plate 205 is made smooth to protect the life buoy 9.

[0039] In the above embodiment, when the drone flies to the rescue area, the life buoy 9 is placed between the two arc plates 205. The surface of the arc plate 205 is made smooth, and the tail end of the arc plate 205 is set to be arc-shaped to prevent the life buoy 9 from being cut when the life buoy 9 is dropped or placed, increasing the loss.

[0040] As Figure 5 shown, a servo motor is fixedly connected to the outer wall of the reel 4, and the output end of the servo motor is fixedly connected to a rotating roller penetrating the side wall of the reel 4. The safety rope 8 is wound around the outer circumference of the rotating roller.

[0041] In the above-described embodiment, when it is necessary to recover the safety rope 8 and the life buoy 9 after the first throw of the life buoy 9 fails, the servo motor can be operated to cause the rotating roller in the reel 4 to rotate. When the rotating roller rotates, the safety rope 8 can be wound around the outer periphery of the rotating roller to recover the safety rope 8 and the life buoy 9.

[0042] As Figure 3 shown, an electric slide rail 5 is provided on the side wall of the reel 4, a limiting ring 501 is provided on the electric slide rail 5, and the safety rope 8 is slidably connected to the inner wall of the limiting ring 501.

[0043] In the above-described embodiment, during the process of recovering the safety rope 8, the electric slide rail 5 provided outside the reel 4 is started. When the electric slide rail 5 operates, it can drive the limiting ring 501 on the electric slide rail 5 to reciprocate left and right, and evenly wind the safety rope 8 onto the rotating roller, facilitating the next throw.

[0044] As Figure 6 shown, the fixing assembly 7 includes a clamping post 701. The clamping post 701 is slidably connected inside the top of the box body 3. An outer wall of the clamping post 701 is fixedly connected with a dial 702. An outer wall of the dial 702 is fixedly connected with a spring 703. One end of the spring 703 is fixedly connected to the inner wall of the box body 3, and the spring 703 is arranged on the outer periphery of the clamping post 701.

[0045] In the above-described embodiment, when the guide ring 6 is worn and needs to be replaced, the dial 702 can be toggled to make the clamping post 701 slide out of the inner wall of the guide ring 6, and at the same time, the spring 703 is compressed. After replacing the new guide ring 6, the dial 702 is released to make the spring 703 rebound to fix the guide ring 6, and it is also convenient to replace the safety rope 8.

[0046] As Figure 5 - Figure 6 shown, a guide ring 6 is provided on the top of the box body 3. One end of the guide ring 6 is slidably connected inside the top of the box body 3. The safety rope 8 can slidably pass through the guide ring 6, and the clamping post 701 is slidably connected to the inner wall of the guide ring 6.

[0047] In the above-described embodiment, the guide ring 6 is fixed in the box body 3 by the clamping post 701. The safety rope 8 passes through the limiting ring 501 and the guide ring 6 respectively and then hangs down, so that the safety rope 8 can pass more smoothly, guide the direction of the safety rope 8, ensure that the safety rope 8 is neatly arranged during the wire release process, and improve the wire release efficiency.

[0048] The working principle of the present utility model is as follows: When the drone is needed, after determining the rescue area, the drone is remotely controlled to fly to the rescue area, and then the driving motor 201 is started. When the driving motor 201 works, it can drive the first gear 202 to rotate. When the first gear 202 rotates, it can drive the second gear 203 to rotate. At the same time, through the transmission shaft 204, another set of the first gear 202 and the second gear 203 can be driven to rotate. When the first gear 202 and the second gear 203 rotate synchronously, two arc plates 205 connected by connecting columns can be driven to approach or move away from each other. When the two arc plates 205 move away from each other, the life buoy 9 placed between the two arc plates 205 can be released and then dropped near the rescued person. A safety rope 8 is tied to the life buoy 9. When the life buoy 9 falls, the rotating roller in the reel 4 is driven to rotate by the servo motor arranged on the side of the reel 4, so that the safety rope 8 falls together with the life buoy 9. If the sea is rough, the life buoy 9 may not be accurately thrown to the rescued person at one time due to the wind and waves during the throw. At this time, the safety rope 8 can be recovered by rotating the servo motor, thereby driving the life buoy 9 to be recovered for a second throw. Another rope is tied to the life buoy 9 and connected to the rescue boat. After the rescued person gets the life buoy 9, the rescued person can be pulled to the rescue boat through this rope. When the safety rope 8 is recovered, the electric slide rail 5 works to drive the limit ring 501 to slide reciprocally, so that the safety rope 8 can be evenly wound on the rotating roller. A guide ring 6 is arranged on the top of the box body 3. The outer circumference of the guide ring 6 is in an arc-shaped smooth style, so that the safety rope 8 is more smooth when being retracted and released. The guide ring 6 is fixed to the top of the box body 3 through the clamping column 701. After long-term use, the guide ring 6 will be worn and needs to be replaced. The toggle piece 702 can be toggled to make the clamping column 701 slide out of the inner wall of the guide ring 6, and at the same time, the spring 703 is compressed. After replacing the new guide ring 6, the toggle piece 702 is released to make the spring 703 rebound to fix the guide ring 6, and it is also convenient to replace the safety rope 8.

[0049] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices and operation methods not specifically described and explained in the present utility model, unless otherwise specified and limited, are implemented according to the conventional means in the art.
