Description

Technical Field

[0001] This utility model relates to the field of marine engineering and marine life-saving equipment technology, and in particular to a reinforced buoyancy marine life raft. Background Technology

[0002] On the vast ocean, ships face numerous unknown risks. Life rafts, as crucial equipment for ensuring the safety of personnel, directly determine the life or death of those in distress at sea. Currently, traditional life rafts have revealed some problems in practical applications that urgently need to be addressed.

[0003] In terms of buoyancy performance, most conventional life rafts rely on a single or limited airbag structure to provide buoyancy. When facing complex sea conditions, such as raging waves and strong winds, their buoyancy stability is poor. Once some airbags are damaged due to collisions, punctures by sharp objects, or other reasons, the overall buoyancy drops significantly, making it difficult to provide reliable support for people in the water. This causes the life raft to lose its floating ability, greatly increasing the risk of drowning.

[0004] In terms of emergency rescue, traditional life rafts generally rely on external power to drive distress signal equipment, such as battery-powered flashlights. However, during long periods of drifting at sea, the battery power is easily depleted. Once the distress signal is interrupted, the life raft becomes like a drop in the ocean, extremely difficult for rescuers to find, causing those in distress to miss precious rescue opportunities.

[0005] In view of the shortcomings of the prior art, this utility model provides a reinforced buoyancy marine life raft to solve the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a reinforced buoyancy marine life raft, including an airbag, a high-pressure gas cylinder connected to the outside of the airbag, an air plate fixedly connected to the lower surface of the airbag, two symmetrically arranged connecting blocks fixedly installed on the lower surface of the air plate, a through hole opened inside each connecting block, an air tube fixedly connected to the lower surface of each connecting block, a balloon fixedly connected to the outer surface of each air tube, a blocking plate provided inside each through hole, a rotating rod fixedly connected to the outer surface of each blocking plate, the rotating rod passing through the connecting block and extending to the outside of the connecting block, a handle fixedly connected to the end of each rotating rod located outside the connecting block, two limiting blocks symmetrical about the center of the blocking plate provided in each through hole, and a distress device provided on the airbag.

[0007] Preferably, the through hole penetrates the bottom of the air plate and the airbag, and connects the inner cavity of the airbag with the lower surface of the connecting block. The air tube is made of soft material and connects the through hole with the inner cavity of the balloon. The diameter of the blocking plate is the same as the cross-sectional diameter of the through hole. In the initial state, the blocking plate is placed vertically, and the limiting block is fixedly connected to the connecting block.

[0008] Preferably, the distress device includes two spherical holes, which are opened inside the connecting blocks. Each spherical hole contains a first sphere, and a first connecting rod is fixedly connected to the lowest point of the outer surface of each first sphere. The lower end of each first connecting rod is fixedly connected to the outer surface of a balloon. Two fixed blocks, symmetrical about the center of the balloon, are fixedly connected to the inner wall of the balloon. A second sphere is rotatably connected to the inner wall of each fixed block. A second connecting rod is fixedly connected to the outer surface of the portion of each second sphere outside the fixed blocks. The outer surfaces of the two second connecting rods are fixedly connected to the same first annular tube. The ends of the two second connecting rods away from the second spheres are fixedly connected to the same second annular tube. An induction coil is spirally wound on the outer surface of the second annular tube. A spherical magnetic block is provided in the inner cavity of the second annular tube.

[0011] Preferably, a hanging ring is fixedly connected to the lowest point of the outer surface of each balloon, and a counterweight is attached to the hanging ring.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model forms a composite buoyancy system through the multiple inflation structure of airbags, air plates and balloons. Under normal use, the balloon can be immersed in water to enhance the overall buoyancy by attaching a counterweight through the hanging ring, ensuring the life raft floats stably. When the airbags or air plates are damaged, the connecting block can be quickly separated to allow the balloon to work independently, providing continuous buoyancy support for people who have fallen into the water and adapting to the survival needs under different dangerous situations.

[0014] 2. This utility model utilizes the swaying of a balloon under the impact of water flow to drive a spherical magnetic block to move inside a ring-shaped tube, causing the induction coil to generate an induced current and store it in a capacitor, providing continuous power for the flashlight. This structure does not require an external power source and can autonomously generate power through environmental energy to drive the distress signal device. It can stably emit distress signals in complex marine environments, expand the search and rescue range, and increase the probability of being found. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-6A reinforced buoyancy marine life raft includes an airbag 1, a high-pressure gas cylinder connected to the outside of the airbag 1, an air plate 2 fixedly connected to the lower surface of the airbag 1, two symmetrically arranged connecting blocks 3 fixedly installed on the lower surface of the air plate 2, each connecting block 3 having a through hole 4 inside, each connecting block 3 having an air pipe 5 fixedly connected to the lower surface of ...

[0024] Furthermore, the through hole 4 penetrates the bottom of the air plate 2 and the air bag 1, and connects the inner cavity of the air bag 1 with the lower surface of the connecting block 3. The air tube 5 is made of soft material and connects the through hole 4 with the inner cavity of the balloon 6. When the balloon 6 shakes, the air tube 5 can deform accordingly, reducing the obstruction to the movement of the balloon 6. The diameter of the blocking plate 7 is the same as the cross-sectional diameter of the through hole 4. In the initial state, the blocking plate 7 is placed vertically, and the gas in the air bag 1 can enter the balloon 6 through the through hole 4. The limiting block 10 is fixedly connected to the connecting block 3.

[0025] Furthermore, the distress device includes two ball holes 11, which are located inside the connecting block 3. Each ball hole 11 contains a first ball 12, and a first connecting rod 13 is fixedly connected to the lowest point of the outer surface of each first ball 12. The lower end of each first connecting rod 13 is fixedly connected to the outer surface of the balloon 6. Two fixed blocks 14, symmetrical about the center of the balloon 6, are fixedly connected to the inner wall of the balloon 6. A second ball 15 is rotatably connected to the inner wall of each fixed block 14, and the outer surface of the portion of each second ball 15 located outside the fixed block 14 is fixed. A second connecting rod 16 is connected to the second connecting rod 16. The outer surfaces of the two second connecting rods 16 are fixedly connected to the same first annular tube 17. The ends of the two second connecting rods 16 away from the second sphere 15 are fixedly connected to the same second annular tube 18. An induction coil 19 is spirally wound on the outer surface of the second annular tube 18. A spherical magnetic block 20 is provided in the inner cavity of the second annular tube 18. The diameter of the spherical magnetic block 20 is smaller than the cross-sectional diameter of the second annular tube 18. The spherical magnetic block 20 can move freely inside the second annular tube 18, thereby generating an induced current in the induction coil 19.

[0026] Furthermore, the distress device also includes a capacitor 21, which is fixedly connected to the upper surface of the air plate 2. A flashlight 22 is fixedly connected to the highest point of the outer surface of the airbag 1. A switch 23 is provided on the outer surface of the flashlight 22. The capacitor 21 can store the current generated by the induction coil 19 for use in other electrical components.

[0027] Furthermore, both induction coils 19 are coupled to capacitor 21. Capacitor 21 is electrically connected to flash lamp 22 and switch 23 via wires. When switch 23 is turned on, flash lamp 22 works and can emit distress signals continuously for a long time.

[0028] Furthermore, each balloon 6 has a hanging ring 24 fixedly connected to the lowest point of its outer surface. The hanging ring 24 is attached to a counterweight. Different counterweights can be attached according to different water environments, so that the buoyancy of the balloon 6 is enhanced without affecting the operation of the airbag 1, and the spherical magnetic block 20 inside moves, thereby generating a continuous current.

[0029] Working Principle: When using this device, open the high-pressure gas cylinder. Gas quickly enters the airbag 1 and air plate 2, then through the through hole 4 and air tube 5 into the balloon 6, causing both the first sphere 12 and the balloon 6 to inflate. Then, hold the handle 9 and rotate it. The handle 9, through the rotating rod 8, drives the blocking plate 7 to rotate until the upper and lower surfaces of the blocking plate 7 contact the two limit blocks 10 respectively, preventing further rotation. At this point, the blocking plate 7 blocks the through hole 4, preventing the gas in the balloon 6 from escaping. When the airbag 1 and air plate 2 are damaged and unusable, the connecting block 3 can be separated from the airbag 1, and the counterweight removed. The balloon 6 can then be used independently to help people who have fallen into the water survive. Under normal circumstances, after the airbag 1, air plate 2, and balloon 6 are fully inflated, the device is placed in the water, and the water level is monitored. A suitable counterweight is hung at the hanging ring 24, allowing the balloon 6 to be submerged in water. This enhances buoyancy without affecting the stable floating of the airbag 1 and air plate 2. The balloon 6 is subjected to the impact of water flow from different directions. The first sphere 12 rotates within the sphere hole 11, causing the balloon 6 to sway continuously, which in turn causes the internal device to sway synchronously. The second sphere 15 can rotate freely within the fixed block 14, allowing the first annular tube 17, the second annular tube 18, and the spherical magnetic block 20 to sway more freely. The spherical magnetic block 20 moves continuously within the second annular tube 18. The induction coil 19 continuously generates induced current and stores it in the capacitor 21. When the switch 23 is turned on, the flashlight 22 works, sending a distress signal to other people who may be passing by in the distance.
