Description

Technical Field

[0001] This invention relates to the field of life raft technology, and in particular to a single-person life raft device comprising a life raft and a life raft packaging device. Background Technology

[0002] Life rafts are currently the main type of lifesaving equipment at sea, with advantages such as ease of use and rapid deployment. However, traditionally used life rafts have poor insulation, leaving rescued personnel exposed to seawater for extended periods, suffering from cold and aquatic life. While a patent application (CN201811145966.9) entitled "A Single-Person Life Raft" includes a canopy and inflatable seat for insulation, this patent does not completely enclose the rescued person within the raft. The top of the canopy remains open, leaving them still vulnerable to cold and aquatic life. Furthermore, when folded and placed in a packaging bag, this raft cannot be self-inflated and deployed without being removed from the bag.

[0003] To protect life rafts, they are currently placed in vacuum bags (see GB2296482 patent). However, vacuum bags are easily punctured by sharp objects. Divers carry life rafts when escaping underwater, but there is currently no convenient life raft packaging device that allows divers to carry it easily, prevents breakage, and allows the life raft to be opened without tearing the vacuum seal beforehand. Summary of the Invention

[0004] In view of the problems and deficiencies of the prior art, the present invention provides a single-person life raft device including a life raft and a life raft packaging device.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] This invention provides a single-person life raft device, characterized in that it includes a life raft and a life raft packaging device. The life raft includes a raft bottom, a float, and a raft canopy. The float is fixed to the edge of the raft bottom, and the float has an air inlet. A mounting cover is fixed to the bottom outer rear end of the float, and an inflation device is installed inside the mounting cover. The bottom edge of the raft canopy is sealed and pasted to the top edge of the float. An opening is opened at the middle of the upper surface of the raft canopy along its length. Matching Velcro fasteners are fixed to both sides of the opening to close it. A transparent window is fixed to the top rear end edge of the raft canopy, and the transparent window is pasted to the open edge of the raft canopy with Velcro to seal the opening.

[0007] The inflation device includes a small compressed air cylinder, the mouth of which is sealed with a cylinder valve. A sealing diaphragm is fixed inside the cylinder valve. A rotating shaft is rotatably arranged between the sealing diaphragm and the end of the cylinder valve away from the small compressed air cylinder inside the cylinder valve. An arc-shaped piston pin is sleeved and fixed on the rotating shaft. An arc-shaped hole is opened on the cylinder valve. An inflation rope is fixed to one end of the arc-shaped piston pin extending out of the arc-shaped hole. A one-way air inlet valve is installed at the bottom of the cylinder valve and is connected to the air inlet of the float tire.

[0008] The life raft packaging device includes an inner packaging bag, a vacuum-sealed bag, and a tamper-evident outer packaging bag. The inner packaging bag includes an inner packaging bag body that can house a folded life raft. Each edge of the surface of the inner packaging bag body has a flange. One flange has a sealing sheet fixed to it, and the other flanges are glued to the sealing sheet. A first through hole is opened on the side of the inner packaging bag body. A bottle valve pull rope is embedded in the first through hole. One end of the bottle valve pull rope is fixed to the inflation pull rope on the life raft, and the other end is placed outside the inner packaging bag body.

[0009] The vacuum-sealed bag includes a vacuum-sealed bag body that can contain an inner packaging bag. The surface of the vacuum-sealed bag body is provided with a zipper. A first vacuum-sealing strip extends from the side of the vacuum-sealed bag body. A bottle valve pull cord is built into the first vacuum-sealing strip. A third through hole is opened on the first vacuum-sealing strip and is located inside the bottle valve pull cord. A pull strap passes through the third through hole and is tied to the bottle valve pull cord.

[0010] The outer packaging bag includes an outer packaging bag body that can be fitted with a vacuum-sealed bag. The upper surface of the outer packaging bag body is provided with Velcro that can be attached to the Velcro on the wetsuit, and the bottom of the outer packaging bag body is fixed with a buckle that can be fastened to the buckle on the wetsuit.

[0011] This invention folds and vacuum-packs the life raft. When needed, the outer packaging bag is opened via a zipper, and the vacuum-sealed bag is removed. Since the life raft is vacuum-packed, there is no need to tear the vacuum-sealed bag beforehand. Simply pull the strap, and the valve rope will pull, thereby pulling the inflation rope of the inflation device on the life raft. This, in turn, pulls the arc-shaped piston pin. The end of the arc-shaped piston pin pierces the sealing film, quickly releasing compressed gas from the small compressed gas cylinder into the life raft's float. During the inflation process, the life raft breaks through the vacuum-sealed bag and opens the inner packaging bag, allowing the life raft to quickly inflate and take shape.

[0012] The life raft of the present invention is equipped with an openable transparent face window. The raft canopy and the transparent face window can cover the top of the float, completely enclosing the person to be rescued in the life raft, providing better thermal protection for divers on the water surface, preventing them from being exposed to seawater for a long time, and avoiding cold and damage from aquatic life, thereby improving the divers' ability to wait for rescue.

[0013] The life raft of this invention is folded and compressed, and then vacuumed to effectively reduce the packaging volume.

[0014] This invention allows divers to easily carry it on their person, is not easily broken, and allows the life raft to be deployed without having to tear open the vacuum-sealed plastic bag beforehand while it is in vacuum packaging. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figure 1-8 As shown, this embodiment provides a single-person life raft device, which includes a life raft and a life raft packaging device.

[0024] Among them, such as Figure 1-4 As shown, the life raft includes a raft bottom 1, a float 2, and a raft canopy 3. The float 2 is fixed to the edge of the raft bottom 1. The float 2 has an air inlet. An installation cover 18 is fixed to the bottom of the outer rear end of the float 2. An inflation device 4 is installed inside the installation cover 18.

[0025] The inflation device 4 includes a compressed small gas cylinder 41. A gas cylinder valve port 42 is sealed at the mouth of the compressed small gas cylinder 41. A sealing diaphragm 43 is fixed inside the gas cylinder valve port 42. A rotating shaft is rotatably arranged between the sealing diaphragm 43 and the end of the gas cylinder valve port 42 away from the compressed small gas cylinder 41. An arc-shaped piston pin 44 is sleeved and fixed on the rotating shaft. An arc-shaped hole is opened on the gas cylinder valve port 42. An inflation pull rope 45 is fixed to one end of the arc-shaped piston pin 44 extending out of the arc-shaped hole. A hand-held ball 46 is fixed to the end of the inflation pull rope 45. The hand-held ball 46 can be an elastic ball. A one-way air inlet valve is installed at the bottom of the gas cylinder valve port 42 and is connected to the air inlet of the float tire.

[0026] The inflation device 4 is installed at the bottom of the float 2. In use, hold the small ball 46 and pull the inflation cord 45, which in turn pulls the arc-shaped piston pin 44. The extension of the arc-shaped piston pin 44 moves within the arc-shaped hole. (See...) Figure 4 Mark 47, the end of the arc-shaped piston pin 44 pierces the sealing diaphragm 43, and the compressed gas in the compressed small gas cylinder 41 inflates the float 2 through the gas cylinder valve port 42 and the one-way air inlet valve. The float 2 opens quickly, and the inflated float 2 can provide corresponding buoyancy. The compressed small gas cylinder 41 is made of aluminum alloy and sealed with a safety diaphragm.

[0027] The bottom edge of the raft canopy 3 is sealed and glued to the top edge of the float 2. An opening is provided in the middle of the upper surface of the raft canopy along the length of the raft canopy. Matching Velcro 5 is fixed on both sides of the opening to close it. A transparent window 6 is fixed to the top edge of the rear end of the raft canopy 3. The transparent window 6 is glued to the edge of the opening of the raft canopy 3 with Velcro 7 to seal the opening of the raft canopy 3.

[0028] In this design, a front balance water bag 8 is fixed to the bottom of the outer front end of the float 2, and side balance water bags 9 are fixed to the bottom of the outer sides of the float 2 to ensure the stability of the life raft when boarding and floating.

[0029] In this design, a double-layered seat cushion 10 is fixed to the inner surface of the floating tire 2. The upper layer of the seat cushion 10 is equipped with a seat cushion inlet pipe with a one-way valve for users to blow air into the seat cushion. The seat cushion 10 is designed to increase the warmth of the people awaiting rescue.

[0030] In this design, the seat cushion 10 is provided with a drain outlet 11, and the drain pipe connected to the drain outlet 11 passes through the seat cushion 10 and the float 2 in sequence. The drain pipe is designed to be separate from the seat cushion 10 and the float 2, that is, the drain pipe is not connected to the seat cushion 10 and the float 2.

[0031] In this design, the inner surface of the floating tire 2 is fitted with three floating tire inlet pipes (not shown in the figure) with one-way valves for users to blow air into the floating tire. The top of the floating tire inlet pipe is inserted through the seat cushion 10 and is designed to be separate from the seat cushion, that is, the floating tire inlet pipe is not connected to the seat cushion 10.

[0032] In this design, a floating anchor 12 is fixed to the outer rear end of the floating tire 2.

[0033] In this design, handrails 13 are fixed to the upper outer sides of both sides of the floating raft 2 for use in boarding and righting the raft.

[0034] In this design, the inner surface of the raft canopy 3 is fitted with a raft canopy inlet pipe 14 with a one-way valve for users to blow air into the raft canopy, thereby increasing the warmth of the people awaiting rescue.

[0035] In this design, a lithium battery signal light 15 is fixed to the top of the rear end of the raft canopy 3. One electrode of the lithium battery signal light 15 can conduct electricity when it contacts seawater, causing the lithium battery signal light to flash, making it easy to spot.

[0036] In this design, the raft canopy 3 is evenly distributed with round rivets 16, which makes the inflated raft canopy structure more stable.

[0037] In this design, the outer surface of the raft canopy 3 is covered with several reflective strips 17 to facilitate discovery by search and rescue personnel.

[0038] In this solution, the compressed absorbent sponge can be folded inside the life raft along with the packaging. It is small in size but has a large water absorption capacity per use. Rescuers can use the compressed absorbent sponge to quickly remove the remaining water inside the raft.

[0039] like Figure 5-8 As shown, the life raft packaging device includes an inner packaging bag 100, a vacuum-sealed bag 200, and an outer packaging bag 300. The inner packaging bag 100, the vacuum-sealed bag 200, and the outer packaging bag 300 are all waterproof bags. The outer packaging bag 300 is made of a puncture-resistant material and is not easily punctured or broken by sharp external objects.

[0040] The inner packaging bag 100 includes an inner packaging bag body 101 that can house a foldable life raft. The inner packaging bag body 101 is square, and each of the four edges of the inner packaging bag body 101 has a flange 102. One of the flanges 102 has a sealing piece 103 sewn on it, and the other three flanges are attached to the sealing piece 103 by Velcro 108. The side of the inner packaging bag body 101 has a first through hole 104 and a second through hole 105. A bottle valve pull rope 106 is embedded in the first through hole 104. One end of the bottle valve pull rope 106 is fixed to the inflation pull rope on the life raft, and the other end is placed outside the inner packaging bag body 101. A hanging rope 107 is embedded in the second through hole 105.

[0041] The vacuum sealing bag 200 includes a vacuum sealing bag body 201 that can contain an inner packaging bag 100. The surface of the vacuum sealing bag body 201 is provided with a zipper 202. A first vacuum sealing strip 203 and a second vacuum sealing strip 204 extend from the side of the vacuum sealing bag body 201. The first vacuum sealing strip 203 has a built-in bottle valve pull cord 106. The first vacuum sealing strip 203 has a third through hole 205, which is located inside the bottle valve pull cord 106. A pull strap 206 passes through the third through hole 205 and is tied to the bottle valve pull cord 106. The second vacuum sealing strip 204 has a built-in hanging cord 107. The second vacuum sealing strip 204 has a fourth through hole 207, which is located inside the hanging cord 107. A hanging strap 208 passes through the fourth through hole 207 and is tied to the hanging cord 107.

[0042] The outer packaging bag 300 includes an outer packaging bag body 301 that can be fitted with a vacuum sealing bag 200. The upper surface of the outer packaging bag body 301 is provided with a Velcro 302 that is attached to the Velcro 401 inside the flange 401 of the wetsuit. The bottom of the outer packaging bag body 301 is fixed with a buckle 303 that is attached to the buckle 402 of the wetsuit 400. The back of the outer packaging bag body 301 is fixed with a strap (not shown in the figure) that is attached to the buckle 403 of the wetsuit 400. The side of the outer packaging bag body 301 is fixed with a hook 304 that is attached to the hook 404 of the wetsuit 400.

[0043] When finished using the life raft, deflate the float 2, raft canopy 3, and seat cushion 10. Fold the life raft with the float 2 as the main body, folding the two sides towards the center axis and the bow and stern towards the transverse axis, folding the inflation device 4 inside, leaving the inflation rope 45 exposed. Continue folding until it reaches a cubic shape. Place the folded life raft in a container such as... Figure 5 In the inner packaging bag shown, specifically tear open the Velcro 108 on the inner packaging bag 100, open the sealing sheet 103, put the folded life raft into the inner packaging bag 100, tie the inflation rope 45 to the cylinder valve rope 106, and stick the Velcro 108 on. In this way, the life raft is placed in the inner packaging bag 100.

[0044] Subsequently, unzip the vacuum-sealed bag 200, place the inner packaging bag 100 inside the vacuum-sealed bag 200, place the bottle valve pull rope 106 inside the first vacuum sealing belt 203, with the third through hole 205 located inside the bottle valve pull rope 106, thread the pull strap 206 through the third through hole 205 and tie it to the bottle valve pull rope 106, place the hanging rope 107 inside the second vacuum sealing belt 204, with the fourth through hole 207 located inside the hanging rope 107, thread the hanging strap 208 through the fourth through hole 207 and tie it to the hanging rope 107, and then perform vacuuming to make the life raft compact as a whole.

[0045] After the life raft is vacuum-packed, it is placed in an outer packaging bag 300. The outer packaging bag 301 is fixed to the inside of the upper flange 401 of the diving suit 400 by Velcro 302. The outer packaging bag 301 is fastened to the upper buckle 402 of the diving suit 400 by hook and loop 303. The outer packaging bag 301 is fixed to the upper buckle 403 of the diving suit 400 by straps. The outer packaging bag 301 is fixed to the upper hook and loop 404 of the diving suit 400 by hook and loop 304. Thus, the outer packaging bag 300 is fixed to the front of the left waist and the front of the left thigh of the diving suit by Velcro, hook and loop, fastening, and hook.

[0046] The installation location and the compact size of the vacuum-sealed bag will not hinder crawling or climbing movements after wearing the raft. When a diver is floating in the water, they can easily detach the life raft by raising their left thigh and quickly deploy it. Specifically, the outer packaging bag 300 is opened via the zipper, and the vacuum-sealed bag 200 is removed. With the life raft vacuum-sealed (without pre-tearing the vacuum-sealed bag 200), pulling the strap 206 will pull the valve rope 106, which in turn pulls the inflation rope 45 of the inflation device 4 on the life raft. This, in turn, pulls the arc-shaped piston pin 44. The end of the arc-shaped piston pin 44 punctures the sealing film 43, quickly releasing compressed gas from the compressed gas cylinder 41 into the float 2 of the life raft. During the inflation process, the life raft breaks through the vacuum-sealed bag 200 and the inner packaging bag 100, and the life raft quickly inflates and takes shape. The pull strap 206 is used to increase the working distance, making it easier to pull the inflation rope 45 effectively and quickly, so that the life raft can be inflated quickly.

[0047] The life raft of this invention, after being folded and compressed, utilizes a vacuum method to effectively reduce its packaging volume. Its shelf life can reach several years, and its performance still meets usage requirements.

[0048] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
