[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] In the description of this invention, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0031] like Figures 1 to 2 As shown, a marine emergency rescue evacuation device of the present invention includes two first air bags 1 distributed on the left and right, and a plurality of second air bags 2 connected between the two first air bags 1. Each second air bag 2 is provided with a plurality of handrails 3, and the two second air bags 2 located on the outer side of the plurality of second air bags 2 are provided with a plurality of arc-shaped air bags 4.

[0032] It also includes a net bag 5, which is located below the first air bag 1 and the second air bag 2. The two outermost second air bags 2 of the two first air bags 1 and the plurality of second air bags 2 are connected to the net bag 5. One of the two first air bags 1 is provided with a plurality of power mechanisms 6.

[0033] The first air bag 1, the second air bag 2, and the arc-shaped air bag 4 are connected.

[0034] Specifically, when an emergency evacuation of personnel working at sea is required, the first air bag 1, the second air bag 2, and the arc-shaped air bag 4 are filled with air. At this time, the first air bag 1 and the second air bag 2 drive the net bag 5 to be in an open state. The first air bag 1, the second air bag 2, and the net bag 5 in the open state are placed in the seawater and float on the sea surface. Personnel can jump directly into the net bag 5. Since the personnel are floating on the sea surface in the net bag 5, a large number of personnel can be placed with the help of the buoyancy of the seawater. The handrail 3 can be used for personnel to hold on for stability. When the net bag 5 is full of personnel, other personnel can crawl into the arc-shaped air bag 4 to facilitate the rescue of more personnel. The first air bag 1, the second air bag 2, and the net bag 5 can be moved at sea by multiple power mechanisms 6, thereby carrying personnel for evacuation.

[0035] By adopting this structure, a large number of offshore workers can be rescued at once, increasing the carrying capacity and enabling rapid transfer and evacuation of personnel, which greatly improves evacuation efficiency. Furthermore, since the first air bag 1, the second air bag 2, and the arc-shaped air bag 4 are inflatable, they can be in a retracted state when not in use, thereby reducing the area and weight occupied and facilitating large-scale deployment during offshore operations.

[0036] Preferred, such as Figures 3 to 5 As shown, it also includes a vertical cylinder 7, which is connected to a first air bag 1. The vertical cylinder 7 is vertical and the opening of the vertical cylinder 7 faces upward. A first waterproof motor 8 is provided inside the vertical cylinder 7. A first rotating shaft 9 is provided at the output end of the first waterproof motor 8. Multiple first fan blades 10 are installed on the first rotating shaft 9.

[0037] A turntable 11 is provided on the outer wall of the first rotating shaft 9, and a rotating ring 12 is rotatably provided on the inner wall of the vertical cylinder 7. Both the turntable 11 and the rotating ring 12 are conical. The rotating ring 12 is located below the turntable 11 and is sleeved on the outside of the first rotating shaft 9. The inner wall of the central circular hole of the rotating ring 12 is close to the outer wall of the first rotating shaft 9, and the outer wall of the turntable 11 is close to the inner wall of the vertical cylinder 7. Centrifugal plates 13 are provided on the top of the turntable 11 and the top of the rotating ring 12. The top of the centrifugal plate 13 on the rotating ring 12 is fixedly connected to the bottom of the turntable 11. Multiple drainage holes 14 are provided on the outer wall of the vertical cylinder 7, and the drainage holes 14 are close to the rotating ring 12.

[0038] Specifically, the first waterproof motor 8 can drive multiple first fan blades 10 to rotate through the first rotating shaft 9. The first fan blades 10 can introduce outside air into the first air bag 1, the second air bag 2 and the arc-shaped air bag 4 through the top opening of the vertical cylinder 7, thereby realizing the inflation work.

[0039] When the first rotating shaft 9 rotates, it synchronously drives the turntable 11, the rotating ring 12, and the centrifugal plate 13 to rotate. When some seawater enters the inner side of the vertical cylinder 7 through the top of the vertical cylinder 7 due to the influence of sea waves, the seawater falls onto the rotating turntable 11. The turntable 11 drives the seawater to rotate centrifugally and is discharged through the drain hole 14. Some seawater flows down along the upper surface of the turntable 11 to the rotating ring 12. The rotating ring 12 also drives the seawater to rotate centrifugally and is discharged through the drain hole 14. The centrifugal plate 13 can enhance the centrifugal effect of the seawater. Outside air can enter between the turntable 11 and the rotating ring 12 through the gap between the turntable 11 and the vertical cylinder 7. The air between the turntable 11 and the rotating ring 12 can enter the first air bag 1 downward through the gap between the rotating ring 12 and the first rotating shaft 9, thereby achieving the purpose of separating seawater and filling it with air.

[0040] In actual use, to save time, a small amount of air can be filled into the first air bag 1 and the device can be placed directly into the seawater. At this time, the device is floating and the vertical cylinder 7 is continuously inhaling air. Personnel can then enter the net bag 5. Since the vertical cylinder 7 floats on the sea surface and the turntable 11, rotating ring 12 and centrifugal plate 13 inside the vertical cylinder 7 can separate the seawater, it is convenient to continuously inflate the device, thereby greatly saving evacuation time.

[0041] Preferred, such as Figure 5 As shown, a sleeve 15 is rotatably sleeved on the outer wall of the first rotating shaft 9, and a turntable 11 is fixedly installed on the outer wall of the sleeve 15. The sleeve 15 and the first rotating shaft 9 are connected by a locking structure.

[0042] Specifically, in non-urgent situations, to facilitate the use of the device, the locking structure can be unlocked and the sleeve 15 can be fixed. At this time, the first rotating shaft 9 rotates inside the sleeve 15, and the turntable 11, rotating ring 12 and centrifugal plate 13 are idle, which facilitates the direct entry of air into the first air bag 1. This avoids the situation where, when the turntable 11, rotating ring 12 and centrifugal plate 13 rotate with the first rotating shaft 9, some air is affected by the turntable 11, rotating ring 12 and centrifugal plate 13 and is directly discharged through the drain hole 14, thereby improving the inflation speed of the device.

[0043] Preferred, such as Figure 5 As shown, the locking structure includes an arc-shaped frame 16, which is vertically slidably mounted on the outer wall of the sleeve 15. A prismatic shaft 17 is provided on the arc-shaped frame 16, and the bottom of the prismatic shaft 17 is slidably inserted into the top of the first rotating shaft 9. A leaf spring 18 is connected between the arc-shaped frame 16 and the turntable 11.

[0044] Specifically, in its natural state, the leaf spring 18 generates an elastic downward force on the bow-shaped frame 16, thereby causing the bow-shaped frame 16 to push the prismatic shaft 17 into the first rotating shaft 9. Due to the shape limitation of the prismatic shaft 17, the first rotating shaft 9 and the sleeve 15 are in a locked state. At this time, the first rotating shaft 9 drives the turntable 11 to rotate synchronously through the sleeve 15. When unlocked, the personnel can pull the bow-shaped frame 16 to lift it. At this time, the prismatic shaft 17 disengages from the first rotating shaft 9, thereby causing the first rotating shaft 9 to rotate inside the sleeve 15, and the sleeve 15 is in a fixed state.

[0045] Preferred, such as Figure 3 As shown, multiple support arms 19 are rotatably provided on the outer wall of the vertical cylinder 7. The multiple support arms 19 are arranged in a ring. The support arms 19 are inclined downward. A float 20 is provided at the end of the support arm 19 away from the vertical cylinder 7.

[0046] Multiple limiting plates 21 are fixedly provided on the outer wall of the vertical cylinder 7. The limiting plates 21 are close to the support arm 19. The limiting plates 21 are inclined. Locking bolts 22 are connected between the limiting plates 21 and the support arm 19.

[0047] Specifically, the limiting plate 21 and the support arm 19 are fixedly connected by locking bolts 22. At this time, the support arm 19 is in an inclined state. When the first air bag 1 is put into the water, the float 20 can float on the sea surface, thereby providing support for the vertical cylinder 7, so that the top opening of the vertical cylinder 7 always faces upward, which is convenient for air intake. When the first air bag 1, the second air bag 2 and the arc-shaped air bag 4 are opened, the locking bolts 22 can be unlocked, and the support arm 19 rotates downward naturally and drives the float 20 to adhere to the outer wall of the vertical cylinder 7. At this time, the locking bolts 22 can be tightened on the limiting plate 21. The end of the locking bolts 22 facing the support arm 19 can abut against the outer wall of the support arm 19, thereby locking the support arm 19 in the retracted state.

[0048] Preferred, such as Figure 3 As shown, it also includes a cover 23, which is fastened to the outer wall of the vertical cylinder 7 and seals the top opening of the vertical cylinder 7 and the multiple drainage holes 14 on the vertical cylinder 7.

[0049] Specifically, after the first air bag 1, the second air bag 2, and the arc-shaped air bag 4 are opened, the cover 23 is sealed onto the vertical cylinder 7, thereby sealing the vertical cylinder 7 and preventing air leakage. At this time, the first waterproof motor 8 stops moving.

[0050] Preferred, such as Figure 1 As shown, it also includes a water baffle 24, which is installed on a first air bag 1. The water baffle 24 is composed of an arc-shaped part and a flat part. The arc-shaped part fits against the outer wall of the first air bag 1, and the flat part is inclined upward. The power mechanism 6 is fixed on the water baffle 24.

[0051] The upper surface of the water baffle 24 is provided with a battery pack 25.

[0052] Specifically, the arc-shaped part of the baffle plate 24 can support and protect the first air bag 1, and the flat part of the baffle plate 24 can suppress seawater, which can prevent the waves from being too large and affecting the vision when the device moves. The battery pack 25 can supply power to the first waterproof motor 8, and the battery pack 25 is waterproof.

[0053] Preferred, such as Figures 6 to 7 As shown, the power mechanism 6 includes a water inlet 26, which is installed at the bottom of the baffle plate 24. The water inlet 26 is inclined downward toward the opening of the net bag 5, and a drain pipe 27 is connected to the opening. The drain pipe 27 is inclined, and a second waterproof motor 28 is provided inside the drain pipe 27. A second rotating shaft 29 is provided at the output end of the second waterproof motor 28, and a plurality of second fan blades 30 are provided on the second rotating shaft 29.

[0054] Specifically, the second waterproof motor 28 is electrically connected to the battery pack 25, and the water inlet 26 is immersed in seawater. When the second waterproof motor 28 is running, it can drive the second fan blade 30 to rotate through the second shaft 29, thereby pushing the seawater in the water inlet 26 through the drain pipe 27 and discharging it backward, thus enabling the device to move on the sea surface. The power mechanism 6 is installed on the first air bag 1 located at the head. When the device moves, it can directly suck the seawater in front of the device into the water inlet 26, thereby reducing the resistance of the seawater to the device and preventing the first air bag 1 located at the head from tilting up when the device is installed on the first air bag 1 at the tail, thus allowing the packaging device to move smoothly on the sea surface.

[0055] In actual use, in order to change the direction of the device when it moves, the power mechanism 6 can be manually rotated on the baffle plate 24 to change the drainage direction of the drain pipe 27. In order to avoid excessive air pressure in the first air bag 1, the second air bag 2 and the arc-shaped air bag 4, a pressure relief valve can be added to the bottom of the first air bag 1. When the device is idle, the cover 23 can be opened and the air in the device can be discharged in reverse through the vertical cylinder 7. A small amount of seawater in the device can also be poured out through the vertical cylinder 7.

[0056] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
