Description

Technical Field

[0001] This invention relates to the field of inflatable lifesaving buoy technology, specifically to a rapidly deployable inflatable lifesaving buoy for water use. Background Technology

[0002] In water rescue scenarios, inflatable buoys are crucial tools for rescuers, providing buoyancy support to those in the water and helping them escape danger. In terms of shipboard support, inflatable buoys can serve as temporary boarding platforms and emergency lifesaving equipment. With the continuous development of related fields, the performance requirements for inflatable buoys are also increasing. They not only need reliable buoyancy but also require breakthroughs in storage portability, ease of deployment, operational stability, and automation to meet the complex and ever-changing needs of different scenarios.

[0003] The deployment process of traditional inflatable floats often requires complex procedures. Manual deployment can involve significant time and effort from operators adjusting the positions of various components, resulting in slow deployment speeds that cannot meet the time-critical requirements of emergency rescue scenarios. While some inflatable floats support inflation and deployment, their poorly designed gas conduction systems can lead to gas leaks and uneven inflation, resulting in slow expansion and irregular shapes after inflation. This makes it difficult to form a stable buoyancy support surface, compromising safety. Summary of the Invention

[0014] The recessed air head is located inside the air strip, and an elastic strip is fixedly connected to the outer end face of the recessed air head. The end of the elastic strip away from the recessed air head is fixedly connected to the inner wall of the air strip. When the air strip is filled with gas, the recessed air head will stretch the elastic strip and pop outward.

[0015] Preferably, the adjusting mechanism includes a straight groove, which is formed on the top of the inflatable float, and a sliding plate is fitted inside the straight groove, while a support shaft seat is fitted outside the sliding plate.

[0016] The outward ejection of the concave air head will squeeze the slide plate, causing the slide plate to move outward along the straight groove along the support seat.

[0017] Preferably, both ends of the support shaft seat are fitted with sliding rods, and a flexible strip is fixedly connected to the end of the sliding rod away from the support shaft seat. The end of the flexible strip away from the support shaft seat is fixedly connected to the edge strip mechanism.

[0018] Preferably, a semi-circular rail is fixedly installed on the top of the inflatable float, the inner wall of the semi-circular rail is slidably adapted to the support seat, and a reset strip is fixedly connected to the outer side of the support seat, with one end of the reset strip away from the support seat being fixedly connected to the top of the inflatable float.

[0019] The support seat moves outward along the inner wall of the semicircular rail, causing the edge mechanism to unfold outward.

[0020] Preferably, the edge mechanism includes a coupling seat, which is fixedly installed on the outer end face of the inflatable float. A flip plate is rotatably installed inside the coupling seat via a shaft, and an edge airbag is fixedly connected to the outer end face of the flip plate.

[0025] Preferably, a tension strip is fixedly connected to the outer side of the flip plate. The tension strip passes through the inner wall of the coupling seat and extends to its outer side. A magnetic shielding plate is fixedly connected to the end of the tension strip away from the flip plate. The magnetic shielding plate passes through the top of the telescopic square tube and extends into its interior, and is used to isolate the magnetic force of the second magnetic block and the first magnetic block.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. In its initial staggered configuration, the unique interlaced rotation structure allows the two inflatable floats to fold tightly, significantly reducing volume. The bearing connection between the first and second rollers and the central shaft, along with the hinge design of the first and second hinge plates, ensures smooth and stable folding. This compact storage configuration effectively saves storage space and facilitates transportation and storage in various scenarios.

[0028] 2. The manual unfolding operation is simple and efficient. Operators only need to move the inflatable float to quickly convert the device from a folded state to a flat structure using the linkage between the hinge and the rollers, saving time for subsequent use. In emergencies, the device supports direct inflation and unfolding. Gas is precisely distributed to the inflation strip through the central elastic tube. The tension generated by the expansion of the inflation strip causes the float to automatically flip and flatten, completing the inflation process. This significantly improves the device's response speed and meets the emergency needs of sudden scenarios.

[0029] 3. As the air pressure in the inflation strip increases, the recessed air head pops out, triggering the adjustment mechanism. Through the linkage of components such as the slide plate and support shaft, the edge mechanism is precisely deployed. The synergistic effect of air pressure drive, magnetic force, and elasticity ensures stable deployment of the edge airbags and maintains good working condition. The interconnected design of the edge airbags and the inflatable float allows them to expand synchronously during the main body inflation process, effectively increasing the overall buoyancy and stability of the float, improving the safety and reliability of the device in complex environments, and reducing risks caused by insufficient buoyancy or structural instability.

[0030] 4. When the air pressure decreases, the elastic strip, reset strip, and other components automatically release potential energy, causing each mechanism to reset. A rational mechanical design and structural connection ensure the orderly retraction of the edge mechanism, adjustment mechanism, etc., and, in conjunction with the hinge and roller structure, allows the inflatable float to fold smoothly back to its initial compact state. The entire storage process is simple to operate, reducing human intervention and the risk of damage to the device due to improper operation. It also reduces the storage volume for quick retrieval next time, achieving efficient cycle of device use and ensuring long-term stable operation. Attached Figure Description

[0045] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be understood that the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0046] Please see Figures 1 to 10 The present invention provides a technical solution:

[0047] Example 1: Initial storage state of the device.

[0048] This embodiment demonstrates the inflatable float device in its unused, stowed state. In the main body of the device, two inflatable floats 6 are hinged to the central shaft 1 via hinge 3 and hinge 5, respectively. Hinges 3 and 5 rotate around the central shaft 1, allowing the inflatable floats 6 to rotate about it. Rollers 2 and 4 are mounted on the central shaft 1 via bearings, and are staggered along the shaft, forming a staggered rotation structure. This allows the two inflatable floats 6 to be tightly folded together, significantly reducing the overall volume and facilitating storage and transportation.

[0049] In the edge mechanism 9, the coupling seat 91 is fixed to the edge of the inflatable float 6 by bolts, and the flip plate 92 is rotatably connected to the coupling seat 91 through a shaft. At this time, the flip plate 92 is in a vertically retracted state, which drives the edge airbag 93 to fold. In the adjustment mechanism 8, the slide plate 82 is embedded in the straight groove 81. The two are connected by a slider-groove sliding connection, which allows the slide plate 82 to slide along the straight groove 81. The bottom of the support seat 83 is provided with rollers, which are rotatably connected to the semi-circular rail 85, and can move along the semi-circular rail 85. One end of the reset bar 84 is connected to the support seat 83 through a hook, and the other end is fixed to the inflatable float 6, which is in a naturally relaxed state.

[0050] Both the inflatable strip 10 and the inflatable float 6 are in a flat, uninflated state. The air inlet pipe 12 is connected to the central elastic tube 11 via a threaded interface, and the port is tightly sealed by a plug through a threaded connection. The resilient protective cover 7 uses elastic straps to wrap around the central shaft 1, the first sleeve roller 2, and the second sleeve roller 4, and is secured with Velcro, providing physical protection for the components in the folded state. Through the above structural design, the device is compact in its folded state, saving space and facilitating storage and transportation in different scenarios; the connection method between the components ensures the stability of the structure, preventing components from loosening or falling off during handling; the resilient protective cover effectively protects key components and extends the service life of the device.

[0051] Example 2: Manual deployment and inflation conduction, as well as main body expansion.

[0052] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in practical applications, the device needs to be unfolded. The operator holds the two inflatable floats 6 in their folded state and applies external force to both sides. Hinges 3 and 5, acting as hinge components, form a rotating pair with the inflatable floats 6 and the central shaft 1, respectively driving rollers 2 and 4 to rotate around the central shaft 1. Rollers 2 and 4 are fixed to hinges 3 and 5 via key connections to ensure synchronized rotation. During rotation, the two inflatable floats 6 gradually unfold from their folded state, eventually forming a near-planar structure as the rotation angle increases. The staggered rotation structure of rollers 2 and 4 on the central shaft 1 ensures the smooth unfolding of the inflatable floats 6, completing the initial manual unfolding step and laying the foundation for subsequent inflation operations.

[0053] In case of emergency, manual deployment is not required; the inflation process can proceed directly. The operator removes the plug from the inlet pipe 12 and connects the outlet of the inflation device to the inlet pipe 12 via a quick connector. The inflation device is then started, and gas flows through the inlet pipe 12 into the central elastic tube 11. The central elastic tube 11 connects to the two inflation strips 10 via a T-shaped tee fitting, serving as a gas distribution hub to evenly distribute the gas to the two inflation strips 10.

[0054] As gas is continuously injected, the internal air pressure of the two inflatable strips 10 gradually increases, causing the originally soft and contractile inflatable strips 10 to rapidly expand and straighten. The bottom of each inflatable strip 10 has a groove 13, which is connected to the internal air cavity of the inflatable float 6 via an interference-fit rubber sealing tube. This allows the tension generated during the expansion of the inflatable strips 10 to automatically flip and flatten the two inflatable floats 6 to both sides. Simultaneously, after filling the inflatable strips 10, gas enters the inflatable floats 6 through the connection channel between the groove 13 and the floats 6, causing the floats 6 to gradually inflate and expand. As the inflation volume increases, the inflatable floats 6 transform from a flat shape into a full airbag structure, forming a stable buoyancy support surface. The manually deployable design is simple to operate, allowing for quick conversion from a stored state to an deployed state; the ability to directly inflate and deploy in emergencies greatly improves the device's response speed and meets the needs of unexpected scenarios. During the inflation process, the connection method of each component ensures the sealing and stability of gas transmission, enabling the inflatable float to expand quickly and evenly, forming a reliable buoyancy structure and providing a guarantee for subsequent use.

[0055] Example 3: Automatic unfolding process of the side panel mechanism.

[0056] like Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, as the internal air pressure of the inflation strip 10 continues to rise, the recessed air head 14, which was originally contracted inside the inflation strip 10, pops outward under the action of air pressure, overcoming the tension of the elastic strip 15. The recessed air head 14 is connected to the inside of the inflation strip 10 by an elastic hinge, ensuring that it can pop out and return to its original position under air pressure. The popped-out recessed air head 14 contacts the sliding plate 82 in the adjustment mechanism 8 and generates compression.

[0057] Under the pressure, the slide plate 82 slides outward along the straight groove 81. The slide plate 82 and the support seat 83 are not connected, only compressed. The movement of the slide plate 82 drives the support seat 83 to move along the semi-circular rail 85, while stretching the reset strip 84 to produce elastic deformation. The support seat 83 is bonded to the edge airbag 93 in the edge mechanism 9 through the sliding rod 86 and the flexible strip 87. The other end of the flexible strip 87 is fixedly connected to the sliding rod 86 by a buckle and has flexibility. Power is transmitted through the sliding rod 86 and the flexible strip 87 to drive the edge mechanism 9 to move.

[0058] In the flange mechanism 9, the flip plate 92 inside the coupling seat 91 rotates around the shaft. The flip plate 92 is fixed to the flange airbag 93 by hot-melt welding, allowing the flange airbag 93 to unfold outward from the retracted state. The flange airbag 93 is connected to the inflatable float 6 through a disc tube 94 and a bent tube 95. The disc tube 94 and the bent tube 95 are connected to the flange airbag 93 and the inflatable float 6 by adhesive bonding, and they inflate and expand synchronously during the inflation of the main body. As the flange airbag 93 unfolds and expands, the overall buoyancy and stability of the float are greatly increased.

[0059] Furthermore, when the flip plate 92 rotates, its outer tension bar 901 is connected to the magnetic shielding plate 90 via a rope, pulling the magnetic shielding plate 90 out of the telescopic square tube 96. The telescopic square tube 96 is composed of multiple hollow tubes slidably connected together through T-slots, while the magnetic shielding plate 90 is inserted into a fixed hollow tube inside the telescopic square tube 96, which is connected to the inflatable float plate 6. Inside the telescopic square tube 96, the first magnetic block 97 is fixed to the inner wall of the telescopic square tube 96 with screws, while the second magnetic block 99 is adhered to the outer wall of the inflatable float plate 6, and the two are in a repulsive relationship. The magnetic force of the first magnetic block 97 and the second magnetic block 99, which were originally isolated from the magnetic force by the magnetic shielding plate 90, is released because the magnetic isolation is removed. The repulsive force between the two magnetic blocks pushes the telescopic square tube 96 to extend outward. Combined with the elastic force of the spring 98, one end of which is fixed to the inner wall of the telescopic square tube 96 and the other end of which is fixed to the inflatable float plate 6, this further assists the edge mechanism 9 in unfolding and maintaining a stable state. Spring 98 serves to retract and reset the telescopic square tube 96. The automatic deployment design of the side panel mechanism enables intelligent operation of the device, eliminating the need for manual intervention and improving efficiency. Through the combined action of pneumatic drive, magnetic force, and elastic force, the side panel airbags can be stably deployed and maintain good working condition, effectively increasing the buoyancy and stability of the float, enhancing the safety and reliability of the device during use, and making it suitable for various complex environments.

[0060] Example 4: Device venting and storage process.

[0061] When the device is finished and needs to be stored, disconnect the inflatable float 6 and the inflatable strip 10 from the inflation equipment, open the vent valve on the inflatable float 6 (which is connected to the air chamber of the inflatable float 6 by a thread), and slowly release the gas in the inflatable strip 10 and the inflatable float 6, so that the air pressure gradually decreases.

[0062] As the air pressure decreases, the elastic strip 15 begins to contract, pulling the recessed air head 14 back to its original position, thus eliminating the squeezing force of the recessed air head 14 on the slide plate 82. In the adjusting mechanism 8, the elastic potential energy stored in the reset strip 84 is released, and the resulting elastic force drives the support seat 83 back to its original position along the semi-circular rail 85. The support seat 83 then pulls the edge mechanism 9 to retract via the sliding rod 86 and the flexible strip 87.

[0063] During the retraction of the edge mechanism 9, the flip plate 92 rotates in the opposite direction, and the tension bar 901 on its outer side drives the magnetic shielding plate 90 to re-insert into the telescopic square tube 96, isolating the repulsive force between the first magnetic block 97 and the second magnetic block 99. The telescopic square tube 96 retracts and resets under the action of the spring 98. Finally, the operator uses the hinge structure of the first hinge piece 3 and the second hinge piece 5 with the central shaft 1 to fold the two inflatable floating plates 6 towards the central shaft 1. Relying on the staggered rotation structure of the first sleeve roller 2 and the second sleeve roller 4 on the central shaft 1, the device is restored to its initial storage state. The air inlet pipe 12 is then sealed with a plug by threaded engagement, and the key components are re-wrapped with a tough protective cover 7 using elastic straps and Velcro, completing the entire storage process. The deflation and storage process is ingeniously designed, with each component automatically resetting, and the operation is simple and quick. Through reasonable structural connections and mechanical design, the device ensures that all components can work closely together during storage, returning to a compact storage state, reducing space occupation, facilitating future use, and also reducing the risk of damage to the device due to improper human operation, thereby improving the device's service life and ease of use.

[0064] The working principle of this invention is as follows: When the device is not in use, the two inflatable floats 6 are folded around the central axis 1 via hinge 3 and hinge 5. Relying on the staggered rotation structure of rollers 2 and 4, the folded structure is compact. At this time, the edge mechanism 9 is in the retracted state, the components of the adjusting mechanism 8 remain in their initial positions, the inflation strip 10 and the inflatable floats 6 are in an uninflated state, and the air inlet pipe 12 is sealed with a plug. A tough protective cover 7 encloses the central axis 1, roller 2, and roller 4 to prevent damage to the components during folding and unfolding.

[0065] Manual unfolding start: In use, the two folded inflatable floats 6 are pried open to the sides by external force. Hinges 3 and 5 drive rollers 2 and 4 to rotate around the central axis 1, gradually unfolding the two inflatable floats 6 from a folded state into a flat structure. Inflation conduction unfolding start: Open the plug of the air inlet pipe 12 and inflate the central elastic tube 11 through the inflation device. The gas is diverted through the central elastic tube 11 to the two inflatable strips 10. The two inflatable strips 10, when fully inflated, will instantly straighten and automatically flip the two inflatable floats 6 to the sides and lay flat. The inflatable strips 10 are connected to the inflatable floats 6 through the bottom groove 13, allowing gas to enter the inflatable floats 6 synchronously, realizing the inflation and expansion of the main structure.

[0066] As the internal air pressure of the inflation strip 10 increases, the recessed air head 14, originally contracted inside the inflation strip 10, overcomes the tension of the elastic strip 15 and pops outward. The popped-out recessed air head 14 presses against the slide plate 82 in the adjusting mechanism 8, causing the slide plate 82 to slide outward along the straight groove 81, thereby pushing the support seat 83 to move along the semi-circular rail 85, while simultaneously stretching the reset strip 84. When the support seat 83 moves, it drives the edge mechanism 9 to move through the sliding rod 86 and the flexible strip 87: the flip plate 92 in the connecting seat 91 rotates around the shaft, causing the edge airbag 93 to unfold outward from the retracted state. The edge airbag 93 is connected to the inflatable float 6 through the disc tube 94 and the bent tube 95, and expands synchronously with the main body as it is inflated, increasing the overall buoyancy and stability of the float. When the flip plate 92 rotates, the tension bar 901 on its outer side pulls the magnetic shielding plate 90 out of the telescopic square tube 96, releasing the magnetic isolation between the first magnetic block 97 and the second magnetic block 99. Due to the repulsive relationship between the two magnetic blocks, the repulsive force pushes the telescopic square tube 96 to extend outward, which, together with the elastic force of the spring 98, further assists the edge mechanism 9 in unfolding and maintaining a stable state.

[0067] When deflated and retracted, the air pressure inside the inflation strip 10 and the inflatable float 6 decreases, causing the elastic strip 15 to contract and pull the recessed air head 14 back to its original position, relieving pressure on the slide plate 82. The elastic force of the reset strip 84 in the adjustment mechanism 8 drives the support shaft 83 back to its original position along the semi-circular rail 85, pulling the edge mechanism 9 up via the sliding rod 86 and the flexible strip 87. Simultaneously, during the retraction of the flip plate 92, the magnetic shielding plate 90 is reinserted into the telescopic square tube 96, isolating the magnetic repulsion force. Finally, the two inflatable floats 6 are folded together via the hinge structure, completing the retraction.

[0068] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any modifications made by those skilled in the art based on the above concepts without creative effort shall fall within the scope of protection of the present invention.
