Description

Technical Field

[0001] The present invention relates to the technical field of inflatable water boards, and specifically to a foldable inflatable board for water rescue with an auxiliary fixing structure. Background Art

[0002] Water rescue refers to the emergency rescue operations carried out for people who have accidents, are in distress or are in a dangerous situation on the water. Its purpose is to quickly and effectively rescue the drowning people from the dangerous waters, ensure their life safety, and minimize injuries and losses as much as possible. During the rescue, various rescue equipment and technologies are required, such as throwing rescue tools to the drowning people through lifebuoys, ropes, throwers, etc., so that they can grab and use these tools to stay afloat or be pulled to a safe area; using water vehicles such as rubber boats, assault boats, and rescue boats to quickly drive towards the drowning people and rescue them. Among many water rescue tools, inflatable boards are widely used during rescue because they are convenient to carry and quickly deploy.

[0003] When the existing inflatable board is in use, it is first inflated by an external air pump. After the inflatable board is inflated to a full state, it is connected to a water vehicle such as a motorboat through an external rope or chain. The water vehicle is used to drive the inflatable board to move on the water, and then it can be taken to the rescue waters for rescue treatment.

[0004] However, during the rescue, when the motorboat drags the inflatable board to move quickly, when the motorboat suddenly accelerates, stops suddenly or makes a sharp turn, the inflatable board will shake violently or skid due to inertia, and it is easy to turn over, which will cause the passengers sitting on the inflatable board to lose their balance and fall into the water, which is not conducive to the development of the rescue operation. Summary of the Invention

One end of the sliding rod away from the pressing plate is connected to the supporting plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. By connecting an external air pump to the air valve, the present invention can quickly inflate the inside of the inflatable plate main body. When inflating the inside of the inflatable plate main body, the gas can enter the driving airbag, causing the driving airbag to expand rapidly. The expanded driving airbag can resist and drive a plurality of floating components, enabling the floating components to extend from the inside of the soft bottom plate, thereby realizing the extension of the floating components. The plurality of floating components can increase the contact area of the inflatable plate with the water surface, thereby improving the overall stability of the inflatable plate on the water surface, reducing the possibility of the inflatable plate tipping over when being towed by a motorboat, and improving the rescue efficiency.

[0021] 2. When the driving airbag inflates and drives the buoyancy-enhancing component, multiple expansion components can be driven synchronously, so that the internal components of the expansion components are in operation, and then the structure of the expansion components expands the deformable bottom pad, so that the deformable bottom pad forms a V-shaped structure at the bottom of the soft bottom plate, and one end forms a cone. The expanded deformable bottom pad forms a cone and a V-shaped structure, which can reduce the water resistance of the inflatable board when it moves on the water surface, improve the water breaking efficiency, reduce the navigation resistance, and improve the towing efficiency of the motorboat. At the same time, when the center of gravity of the lifeguard shifts when the inflatable board moves, causing the inflatable board to tilt, the inclined bottom surface of the V-shaped structure can offset part of the centrifugal force through the reaction force of the water flow on the inclined surface, reduce the side slip or tilt of the inflatable board, enhance the lateral stability, reduce the risk of rollover, and thus reduce the possibility of the inflatable board rolling over when it is towed by the motorboat, thereby cooperating with the buoyancy-enhancing component to enhance the overall stability of the inflatable board and improve the rescue efficiency and safety;

[0022] 3. When the lifeguard's center of gravity shifts when the inflatable board moves, causing the inflatable board to tilt, the lifeguard will move his body toward the edge of the inflatable board body due to the shift in center of gravity. At this time, the protrusion will be squeezed, so that the squeezing force is transmitted to the pressing component. When the pressing component is subjected to force, its internal components are pressed toward the direction of the buoyancy component, thereby driving the unfolded buoyancy component, so that the internal components of the buoyancy component are tilted and upward due to the driving force, so that the plates inside the buoyancy component form an inclined shape. The inclined plates will increase the contact area and resistance with water in the water. When the inflatable board is subject to external force and tends to roll over, the water resistance of the plates will generate a force in the opposite direction of the rollover, which plays a role in hindering the rollover, reducing the possibility of the inflatable board rolling over when moving, improving the overall stability, reducing the possibility of the lifeguard slipping off the inflatable board, and improving the rescue efficiency and safety.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1

[0037] See also Figures 1 to 7, which is the first embodiment of the present invention, provides a technical solution: a foldable inflatable board with an auxiliary fixing structure for water lifesaving, including an inflatable board body 1, and a soft bottom plate 2 is fixedly connected to the bottom of the inflatable board body 1. Here, the inflatable board body 1 and the soft bottom plate 2 are both made of thermoplastic polyurethane, which has the advantages of tear strength, high wear resistance and low risk of air leakage, and can be easily folded into a small volume. There is no permanent crease after folding, and the recovery is good, which is suitable for high-frequency use. The bottom of the soft bottom plate 2 is fixedly connected to a deformable bottom pad 3. The deformable bottom pad 3 is made of rubber material, has strong elasticity, and can recover to its original shape after stretching. The inflatable board body 1 is in a shape that can cope with the need for repeated expansion and can be immersed in water for a long time, and has a good waterproof effect. A plurality of traction columns 11 are fixedly connected to one end of the top of the inflatable board body 1, and protrusions 5 are arranged on both sides of the top of the inflatable board body 1. The protrusions 5 are protrusions on the inflatable board body 1. After being subjected to external force, a force is formed on the inside of the inflatable board body 1, which is convenient for driving the internal structure of the soft bottom board 2. An air valve 12 is fixedly connected to one side of the top of the inflatable board body 1. An inner cavity 21 is provided inside the soft bottom board 2. A driving airbag 7 is installed in the middle of the inner cavity 21. The inflatable board body 1 and the driving airbag 7 are mutually connected. Here, the bottom of the inflatable board body 1 is connected with the driving airbag 7. When the inflatable board body 1 is inflated through the air valve 12, as the gas enters, the gas inside the inflatable board body 1 can enter the driving airbag 7, thereby realizing the opening of the driving airbag 7. The periphery of the connection between the inflatable board body 1 and the driving airbag 7 is sealed to prevent the gas inside the inflatable board body 1 from leaking from the connection. A plurality of mutually symmetrical buoyancy increasing components 4 are installed on both sides of the inner cavity 21. One side of the buoyancy increasing component 4 is in contact with the driving airbag 7. Here, the buoyancy increasing component 4 can be resisted by the gradually inflated driving airbag 7. Drive, push it out from the soft bottom plate 2, so as to realize the driving of the driving airbag 7 to the buoyancy component 4. The bottom of the soft bottom plate 2 is fixedly connected with a plurality of expansion components 8, and the expansion components 8 are located inside the deformable bottom pad 3. The expansion components 8 are in contact with the driving airbag 7. Both sides of the top of the soft bottom plate 2 are fixedly connected with a plurality of pressing components 6, and the pressing components 6 are located above the buoyancy component 4. Here, when the driving airbag 7 is fully inflated, the buoyancy component 4 is pushed out from the soft bottom plate 2 to achieve full extension. At this time, the pressing components 6 correspond to each other with the buoyancy component 4, and the buoyancy component 4 can be driven by the downward pressing components 6;

[0038] The inflatable board body 1, the soft bottom board 2 and the deformable bottom pad 3 are unfolded, and the external air pump is connected to the air valve 12 to inflate the inside of the inflatable board body 1 so that the inflatable board body 1 expands rapidly. During inflation, the driving airbag 7 is inflated to expand the driving airbag 7. The expanded driving airbag 7 squeezes and drives the multiple flotation-increasing components 4, and the multiple flotation-increasing components 4 are pushed out and stretched from the soft bottom board 2. At the same time, the expanded driving airbag 7 drives the multiple expansion components 8, so that the expansion components 8 are placed on the top of the deformable bottom pad 3, so that the deformable bottom pad 3 is unfolded into a V shape, and the inflatable board can be quickly unfolded.

[0039] A plurality of fixing straps 13 are installed on the top of the inflatable board body 1. Here, the fixing straps 13 are connected by Velcro, which can quickly restrain the rescued person and facilitate the rescue work. The top of the inflatable board body 1 is provided with anti-slip grooves. The anti-slip grooves can increase the friction between the human body and the inflatable board body 1, reduce the possibility of people sliding on the inflatable board body 1, and reduce the possibility of people slipping off the inflatable board body 1. A plurality of protective handles are installed on the raised portion 5.

[0040] Multiple storage cavities are provided on both sides of the interior of the soft bottom plate 2. The buoyancy-enhancing component 4 includes a buoyancy member slidably installed inside the storage cavity. Here, the interior of the storage cavity is smoothed to reduce the friction between the buoyancy member and the storage cavity, so that the buoyancy member can move more smoothly inside the storage cavity, which is convenient for the rapid deployment and retraction of the buoyancy member. One side of the buoyancy member is fixedly connected with mutually symmetrical connecting rods 43, and the end of the connecting rod 43 away from the buoyancy member is fixedly connected with a driving plate 44. The driving plate 44 is in contact with the driving airbag 7, and one side of the driving plate 44 is in contact with the side of the driving airbag 7. The driving airbag 7 can push the driving plate 44 against the driving plate 44, so that the buoyancy member can be pushed out from the inside of the storage cavity and deployed. A reset spring 45 is sleeved on the connecting rod 43.

[0041] The buoyancy member includes a floating plate 41 slidably connected to the inside of the storage cavity, and one side of the floating plate 41 is rotatably connected to the floating plate 42. A waterproof sleeve 47 is installed on the outer side of the floating plate 41 and the floating plate 42. The waterproof sleeve 47 is made of thermoplastic polyurethane material and can change with the rotation of the floating plate 41 and the floating plate 42 to prevent water from flowing into the driving chamber. A driving chamber is opened in the middle of the floating plate 41. Here, a through opening is opened at the top of the driving chamber for adapting to the installation of a component of a linkage member 46. A linkage member 46 is installed in the driving chamber, and the linkage member 46 is connected to the floating plate 42 in a transmission manner.

[0042] When launching a rescue operation, the inflatable board in the folded state can be unfolded and laid flat first, and connected to the air valve 12 through an external air pump. Under the operation of the air pump, gas is transported to the inside of the inflatable board body 1, so that the inflatable board body 1 expands rapidly and is then quickly filled. When the inflatable board body 1 is inflated, part of the gas inside the inflatable board body 1 can enter the driving airbag 7, so that the driving airbag 7 expands rapidly. The inflated driving airbag 7 can be used to top the multiple driving plates 44, so that the driving plates 44 are forced to move in the inner cavity 21, and the connecting rod 43 is driven, thereby pushing the entire buoyancy member, so that the floating plate 1 41 and the floating plate 2 42 extend from the inside of the storage cavity. The extended floating plate 1 41 and the floating plate 2 42 can increase the contact area between the inflatable board and the water surface, thereby improving the buoyancy when encountering water and enhancing the stability of the inflatable board.

[0043] When the inflatable board body 1 is fully inflated, the driving airbag 7 will expand to its maximum value. At this time, the buoyancy-enhancing component 4 is in a fully extended state and can be put on the water for use. When in use, multiple traction columns 11 are wrapped around an external traction rope or chain and connected to the tail of an external motorboat. The inflatable board is dragged and moved by the motorboat, thereby driving it to quickly reach the rescue waters.

[0044] When use is finished, the air valve 12 can be manually operated or an external air pump can be connected to discharge the gas inside the inflatable board body 1. At this time, the gas inside the driving airbag 7 will shrink as the gas inside the inflatable board body 1 is lost, thereby releasing the resistance to the driving plate 44. Under the elastic action of the reset spring 1 45, the driving plate 44 is pushed up, so that the connecting rod 43 drives the floating plate 1 41 and the floating plate 2 42 to move toward the inside of the storage cavity, thereby realizing the automatic recovery of the buoyancy component 4. After it is completely deflated, the inflatable board can be manually folded and recovered.

[0045] Example 2

[0046] See also Figures 8 to 10, which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the linkage member 46 includes a vertical rod 461 fixedly connected to one side inside the driving chamber. The top end of the vertical rod 461 is connected through a force-receiving piece 463. Here, the force-receiving piece 463 is slidably installed in the through-opening. When the buoyancy member moves and extends to form a static state, at this time, the force-receiving piece 463 and the pressing assembly 6 are on the same axis, and a second reset spring 462 is sleeved on the vertical rod 461. A linkage plate 464 is rotatably connected to the side of the force-receiving piece 463 away from the vertical rod 461. One end of the linkage plate 464 away from the force-receiving piece 463 is rotatably connected to a slider 465. The slider 465 is slidably installed inside the driving chamber. A sliding track is provided inside the driving chamber, and the slider 465 is installed inside the sliding track. A pushing plate 466 is rotatably connected to the top side of the slider 465 away from the linkage plate 464. One end of the pushing plate 466 away from the slider 465 is rotatably connected to the second floating plate 42.

[0047] The pressing assembly 6 includes a connection box 61 fixedly connected to one side of the top of the soft bottom plate 2. Both sides of the bottom of the connection box 61 are fixedly connected with spring telescopic rods 62. The top ends of the spring telescopic rods 62 are rotatably connected with a force-receiving member. Here, the spring telescopic rod 62 is composed of a sleeve rod, an inner rod, and a spring, and is used to reset the force-receiving member.

[0048] The force-receiving member includes a force-receiving plate 63 rotatably connected to the top end of the spring telescopic rod 62. The force-receiving plate 63 can be rotatably connected to the spring telescopic rod 62 through a spring reset bearing. The movable force-receiving plate 63 is adapted to receive the downward driving force around the protruding portion 5. When the driving force disappears, the force-receiving plate 63 is reset through the spring reset bearing. A pressing rod 64 is rotatably connected to the bottom of the force-receiving plate 63. Here, the top of the force-receiving plate 63 is arc-shaped and fits the inner wall of the inflatable plate main body 1. The force-receiving plate 63 and the protruding portion 5 are on the same axis. One end of the pressing rod 64 away from the force-receiving plate 63 is fixedly connected with an extrusion plate 65. The pressing rod 64 penetrates through the connection box 61.

[0049] A plurality of air isolation channels 14 are fixedly connected inside the inflatable plate main body 1. One end of the air isolation channel 14 is hermetically connected to the top end of the connection box 61. Here, the caliber size of the air isolation channel 14 is the same as that of the connection box 61. The air isolation channel 14 and the connection box 61 are connected through sealing treatment, so that a sealed state is formed inside the inflatable plate main body 1 to prevent gas from leaking from the air isolation channel 14 and the connection box 61. At the same time, after the air isolation channel 14 and the connection box 61 are hermetically connected, a closed space is formed inside, which is convenient for the activities of the internal components of the pressing assembly 6.

[0050] When the inflatable board is towed and moved by the motorboat, when the lifeguard's center of gravity shifts during the movement of the inflatable board and causes the inflatable board to tilt, the lifeguard's body will move toward the edge of the inflatable board body 1 due to the shift in center of gravity. At this time, the protrusion 5 will be squeezed, so that the force-bearing plate 63 moves downward under the squeezing force, thereby driving the pressure rod 64 to move downward, thereby driving the squeezing plate 65 to move toward the force-bearing piece 463, and resisting and pressing the force-bearing piece 463 downward, so that the force-bearing piece 463 slides downward on the vertical rod 461, thereby driving the linkage plate 464 to move around the rotation point, so that one end of the linkage plate 464 pushes the slider 465 toward the direction of the floating board 42, and the moving slider 465 can push the push plate 4 66 is driven, thereby driving the floating board 2 42 to rotate around the rotation point, so that the floating board 2 42 is in an inclined state, and the contact area and resistance with the water are increased by the inclined floating board 2 42 in the water. When the inflatable board is subjected to an external force and tends to roll over, the water resistance of the floating board 2 42 will generate a force in the opposite direction of the rollover, which plays a role in hindering the rollover and reduces the possibility of the inflatable board rolling over when moving. At the same time, the inclined floating board 2 42 can form an additional buoyancy area around the inflatable board. When the inflatable board is tilted, more water is displaced, and the buoyancy is increased, which helps to straighten the inflatable board, improve the overall stability, and reduce the possibility of lifeguards slipping off the inflatable board.

[0051] When the rescuer's center of gravity returns to the right position, the protrusion 5 loses the squeezing force. At this time, the force-bearing plate 63 is reset by the spring telescopic rod 62. After the force-bearing plate 463 loses the downward pressure, the force-bearing plate 463 is reset by the elastic action of the reset spring 2 462, thereby driving the floating plate 2 42 to reset.

[0052] The remaining structures are the same as those of Example 1.

[0053] Example 3

[0054] See also Figure 6 and Figure 11 , which is the third embodiment of the present invention. This embodiment is different from the first and second embodiments in that: the support component 8 includes an L-shaped connecting plate 81 symmetrically fixedly connected to the bottom of the soft bottom plate 2, and an elastic pressure piece is installed on the L-shaped connecting plate 81. The bottom of the elastic pressure piece is fixedly connected to a support plate 85. Here, the bottom of the support plate 85 is in an arc shape, which can reduce scratches on the deformable bottom pad 3.

[0055] The elastic pressure piece includes a sliding rod 82 symmetrically connected to the L-shaped connecting plate 81, the top of the sliding rod 82 is fixedly connected to a pressure plate 84, and a return spring 83 is sleeved on the sliding rod 82, and the end of the sliding rod 82 away from the pressure plate 84 is connected to the support plate 85, here, the top of the pressure plate 84 is in contact with the bottom of the driving airbag 7, and the driving airbag 7 can apply a driving force to the pressure plate 84, and the support plate 85 is located below the L-shaped connecting plate 81, when the support plate 85 moves downward, the L-shaped connecting plate 81 will not interfere with the support plate 85.

[0056] When the driving airbag 7 is inflated and drives the driving plate 44, multiple pressure plates 84 can be driven synchronously, so that the pressure plate 84 is forced to drive the slide bar 82 to move downward, and drive the support plate 85 to move toward the direction of the deformable bottom pad 3. The deformable bottom pad 3 is resisted and stretched by multiple support plates 85, so that the deformable bottom pad 3 forms a V-shaped structure at the bottom of the soft bottom plate 2, and one end forms a cone. The expanded deformable bottom pad 3 forms a cone and a V-shaped structure, which can reduce the water resistance of the inflatable board when moving on the water surface, improve the water breaking efficiency, reduce the navigation resistance, and improve the towing efficiency of the motorboat. At the same time, when the center of gravity of the lifeguard shifts when the inflatable board moves and causes the inflatable board to tilt, the inclined bottom surface of the V-shaped structure can offset part of the centrifugal force through the reaction force of the water flow on the inclined surface, reduce the side slip or tilt of the inflatable board, thereby cooperating with the buoyancy-increasing component 4 to enhance the lateral stability of the inflatable board and reduce the risk of rollover.

[0057] When use is completed, the airbag 7 is driven to exhaust and shrink, and the force on the pressure plate 84 can be cancelled. At this time, the pressure plate 84 is pushed back to its original position by the elastic action of the return spring 3 83, and then the support plate 85 is reset, so that the deformable base pad 3 is retracted to its original position.

[0058] The remaining structures are the same as those of embodiments 1 and 2.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
