Description

Technical Field

[0001] The invention belongs to the technical field of marine life-saving equipment, in particular to a life-saving strong buoyancy device for marine rescue. Background Art

[0002] The life-saving buoyancy device used for maritime rescue is specially designed for rescue after emergencies such as shipwrecks, tsunamis, floods, etc. It aims to provide buoyancy, protection and life-saving support to ensure that people in distress can be rescued safely.

[0003] The life-saving buoyancy device for marine rescue in the prior art adopts a buoy and a main structure in combination, and is used after being equipped with an air supply component. When a person who falls into the water pulls the buoyancy device, the air supply component is activated to further fill the buoyancy airbag to increase the buoyancy, thereby achieving rescue. However, in some cases, the buoyancy device may be pulled into the water by the trapped person, and the air intake of the buoyancy device immersed in the water will open in the water when it is activated, so that water is sucked in instead of gas, causing an air pump failure, making it difficult to achieve enhanced inflation and buoyancy.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention utilizes a middle frame installed at the inner side of a support tube, and has an air supply component built into the middle frame, cooperates with a float air suction component installed at the outer side of the support tube, and cooperates with a magnetically connected float. When the main body of the lifesaving strong flotation device is dragged into the water body by a drowning person, the magnetic float can be separated and floated independently. In conjunction with a pressure valve installed on the top of the float, when the main body of the strong flotation device is immersed in water, the air suction port is guaranteed to be located above the liquid surface. Therefore, when the air supply component is started, air is stably inhaled from above the liquid surface, gas is replenished to the airbag cover component, and special air is supplied to the strong flotation airbag, which effectively avoids the strong flotation device from being unable to inhale gas from the air to enhance its own buoyancy when it is immersed in water.

[0016] 2. The present invention reuses the air supply component and its effect of stably inhaling and pumping air. Before actual rescue, a small amount of inflation is maintained to reduce the excessive volume of the flotation mechanism after inflation, so that it can float smoothly even with a smaller volume. When used for rescue, the strong flotation device with reduced volume is used to quickly throw it to the target rescue area to avoid excessive throwing resistance when the volume is too large. When thrown to the target rescue area, the rapid inflation effect of the device is reused to fill it with gas in time and inflate the strong flotation airbag in time. When buoyancy rescue is needed, the volume and buoyancy are expanded, and the throwing effect is improved when it is thrown.

[0017] 3. The present invention reuses the air supply component and cooperates with the control reversing component to adjust the air outlet direction to input the gas into different jet push tubes, and through the remote opening and closing control of different No. 2 valves, a single No. 2 valve is opened in one direction, and the gas is guided to the corresponding jet push tube to be ejected. The reaction buoyancy is used to push the device to float, and then it can actively float toward the person who falls into the water on the water surface, thereby improving the rescue accuracy and efficiency, avoiding the strong flotation device from being too far away from the person who falls into the water, and improving the life-saving effect.

[0018] 4. The present invention reuses the magnetic float and cooperates with the hidden storage pipeline. After the nearby drowning person is successfully rescued, the float is thrown out and thrown toward other drowning people, so that other drowning people can be further rescued by grabbing the float. For a single set of life-saving strong flotation device, the rescue effect of multiple people is achieved, thereby improving the emergency rescue effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] 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.

[0029] like Figures 1 to 8As shown, an embodiment of the present invention provides a lifesaving strong buoyancy device for marine rescue, comprising a support tube 1, a through hole 2 is opened at the top of the outer surface of the support tube 1, an air bag sleeve assembly 5 is fixedly sleeved on the outer surface of the support tube 1, a middle frame 3 is provided on the inner side of the support tube 1, a connecting pipe 4 is fixedly connected between the middle frame 3 and the support tube 1, an air supply assembly 6 is fixedly provided inside the middle frame 3, an isolation ring 7 is provided inside the middle frame 3, a floating ball air suction assembly 9 is fixedly provided on the top of the outer surface of the support tube 1, a top sleeve 8 is fixedly provided on the top of the middle frame 3, and the top sleeve 8 is fixedly connected to the floating ball air suction assembly 9, a strong buoyancy air bag 10 is fixedly provided on the bottom of the middle frame 3, a control reversing assembly 14 is fixedly provided on the top of the middle frame 3, and the inner end of the control reversing assembly 14 is located inside the middle frame 3;

[0030] The float suction assembly 9 includes a float 91, a connecting frame 92, a fixing frame 93, a magnetic seat 94, a hose 95 and a pressure valve 96. The pressure valve 96 opens when there is a negative pressure inside the hose 95. The air supply assembly 6 inhales gas through the float suction assembly 9 and inputs the gas into the support tube 1.

[0031] Embodiment 1: During use, when it is necessary to throw it near a person who falls into the water, a small amount of ventilation is maintained inside the airbag cover assembly 5 in the initial state. At this time, the volume of the strong flotation device is small. The strong flotation device is rotated and thrown near the person who falls into the water. The strong flotation device floats near the person who falls into the water, and the air supply assembly 6 is remotely started. As the air pump 61 is started, the air pump 61 draws gas toward the inside of the float suction assembly 9 through the No. 2 pipe 63 and the top sleeve 8, so that the air pressure inside the hose 95 is reduced, so that the pressure valve 96 is opened, and the ambient air is sucked in through the pressure valve 96, the hose 95, the top sleeve 8 and the No. 2 pipe 63, and is input into the annular space surrounded by the middle frame 3 and the isolation ring 7 through the No. 1 pipe 62, and is input into each connecting pipe 4, so that the gas is input into the inside of the support tube 1, and the input gas entering the support tube 1 is quickly passed through the through hole 2 into the airbag cover 52 of the airbag cover assembly 5, so that the airbag cover 52 is quickly After the strong float device is inflated and expanded to form a complete strong float device, the person who falls into the water grabs the strong float device; when the person who falls into the water grabs the strong float device for the first time and sinks directly, as the strong float device follows the person who falls into the water and sinks into the water at the same time, the float 91 in the float suction assembly 9 bears the enhanced buoyancy during immersion and drives the magnetic seat 94 to separate from the fixed frame 93, and keeps floating alone, and then starts the air supply assembly 6, so that when the air supply assembly 6 is immersed in water, it uses the floating independent float 91 to complete the suction of air on the water surface, and quickly and completely inputs the gas into the airbag cover 52, so that the airbag cover 52 is quickly further filled with gas and the buoyancy is increased, and then the No. 1 valve 11 is further opened, so that the introduced gas is further introduced into the strong float airbag 10 through the No. 1 valve 11, so that the hidden and contracted strong float airbag 10 is quickly inflated when the strong float device is immersed in water, and the buoyancy of the strong float device is further increased and floated.

[0032] Firstly, by utilizing the middle frame 3 installed at the inner side of the support tube 1, and by building an air supply assembly 6 in the middle frame 3, in conjunction with the float air suction assembly 9 installed at the outer side of the support tube 1, and in conjunction with the magnetically connected float 91, when the main body of the lifesaving strong flotation device is dragged into the water body by the drowning person, the magnetic float 91 can be separated and floated independently, and in conjunction with the pressure valve 96 installed on the top of the float 91, when the main body of the strong flotation device is immersed in water, it is ensured that the air suction port is located above the liquid surface, so that when the air supply assembly 6 is started, air is stably inhaled from above the liquid surface, the air bag cover assembly 5 is supplemented with gas, and the strong flotation air bag 10 is specially supplied with air, effectively avoiding the strong flotation device from being unable to inhale gas from the air to enhance its own buoyancy when it is immersed in water. For the situation where some strong flotation devices are dragged into the water by the drowning person, stable enhanced air supply and floating can still be achieved, providing strong flotation capability and improving the rescue effect.

[0033] In addition, by reusing the air supply assembly 6 and utilizing its stable air intake and pumping effect, a small amount of inflation is maintained before actual rescue use to reduce the excessive volume of the flotation mechanism after inflation, so that buoyancy can be successfully used even with a smaller volume. When used for rescue, the reduced-volume strong flotation device is used to quickly throw it to the target rescue area to avoid excessive throwing resistance when the volume is too large. When thrown to the target rescue area, the rapid inflation effect of the device is utilized again to fill it with gas in time and inflate the strong flotation airbag 10 in time, so that the volume and buoyancy are expanded when buoyancy rescue is needed, thereby improving the throwing effect when it is thrown.

[0034] Embodiment 2: When the throwing position deviates, the control reversing assembly 14 is started, so that the electric push rod 142 drives the movable ring 141 to move upward along the outer side of the isolation ring 7, so that the isolation ring 7 blocks the connecting hole connected to the connecting pipe 4, so that the open port of the No. 2 valve 13 is connected to the No. 2 pipe 63, and according to the position and direction of the strong flotation device and the person who falls into the water, the No. 2 valve 13 in the corresponding direction of the side through hole 12 is remotely opened, so that the air supply assembly 6 sucks in the gas and passes it into the corresponding No. 2 valve 13, and then the air flow is input into the corresponding jet push pipe 15. As the gas sucked in and pressurized by the pump is ejected along the jet push pipe 15, the strong flotation device floating on the water surface is pushed to move toward the person who falls into the water, completing the position calibration.

[0035] First, by reusing the air supply component 6 and cooperating with the control reversing component 14, the gas is input into different jet push tubes 15 by adjusting the gas outlet direction, and through the remote opening and closing control of different No. 2 valves 13, the single No. 2 valve 13 is opened in one direction, and the gas is guided to the corresponding jet push tube 15 to be ejected by utilizing the reaction buoyancy to propel the device to float, and then it can actively float toward the person who falls into the water on the water surface, thereby improving the accuracy of rescue, improving the efficiency of rescue, avoiding the strong flotation device from being too far away from the person who falls into the water, and improving the life-saving effect.

[0036] Embodiment 3: When there are multiple people falling into the water, the person who is rescued by the strong flotation device and sitting on the strong flotation device grabs the float in the float suction assembly 9, and further pulls out the pipeline hidden in the fixed frame 93, and takes out the float and throws it to other people who fall into the water nearby, so that other people who fall into the water can be further rescued by grabbing the thrown float, completing the rescue of multiple people by a single set of strong flotation device.

[0037] Firstly, by reusing the magnetic float 91 in combination with the hidden storage hose 95, after the nearby drowning person is successfully rescued, the float 91 is thrown out and thrown toward other drowning persons, so that other drowning persons can be further rescued by grabbing the float. For a single set of life-saving strong buoyancy device, a multi-person rescue effect is achieved, thereby improving the emergency rescue effect.

[0038] Among them, the fixed frame 93 is fixedly connected to the top of the outer surface of the support tube 1, one end of the connecting frame 92 is fixedly connected to the side of the fixed frame 93 and the other end is fixedly connected to the side of the top sleeve 8, the magnetic seat 94 is fixedly connected to the bottom of the float 91 and movably sleeved on the top of the fixed frame 93 and magnetically attracted to the top of the fixed frame 93, one end of the hose 95 is fixedly connected to the side of the top sleeve 8 and the other end is fixedly sleeved in the float 91, one end of the hose 95 passes through the float 91 and extends to the top of the float 91, and the pressure valve 96 is fixed at the top of the hose 95.

[0039] The magnetic base 94 is magnetically fixed to the fixed frame 93 by utilizing the magnetic attraction. The magnetic attraction is utilized to ensure that the device will not separate when thrown, and it will separate when pulled out manually or when it is acted upon by buoyancy. The hose 95 has a certain length and is stacked and hidden in the fixed frame 93 for extended use.

[0040] Among them, the airbag cover assembly 5 includes a support plate 51 and an airbag cover 52. The support plate 51 is fixedly sleeved on the outer surface of the support tube 1. The airbag cover 52 is fixedly connected between the support plates 51 and sleeved on the outer side of the support tube 1. The airbag cover 52 is connected to the through hole 2.

[0041] A certain amount of gas is injected into the airbag cover assembly 5 in the initial state to maintain the initial buoyancy, and the airbag cover assembly 5 further expands when further gas is input into the matching through hole 2 to increase the buoyancy.

[0042] Among them, the air supply assembly 6 includes an air pump 61, a No. 1 pipe 62, a No. 2 pipe 63 and a battery 64. The air pump 61 is fixedly installed in the middle frame 3, the No. 1 pipe 62 is fixedly connected to the output end of the air pump 61, the No. 2 pipe 63 is fixedly connected to the suction end of the air pump 61, the top of the No. 2 pipe 63 is connected to the top sleeve 8, the outer end of the No. 1 pipe 62 passes through the isolation ring 7, and the battery 64 is fixedly installed in the middle frame 2.

[0043] The air supply assembly 6 provides inflation gas and pushing pressure air to achieve strong floating effect and moving propulsion effect, and the battery 64 provides power for electrical equipment.

[0044] Among them, a valve No. 11 is provided at the bottom of the middle frame 3, and the valve No. 11 is opened unidirectionally toward the inside of the strong floating airbag 10. The valve No. 11 is located on the outside of the isolation ring 7. A side through hole 12 is provided on the outer surface of the middle frame 3, and a valve No. 2 is fixedly sleeved inside the side through hole 12. There are four side through holes 12, and the four side through holes 12 are distributed in a ring with equal intervals. A jet push pipe 15 is fixedly provided on the outer side surface of the middle frame 3, and the jet push pipe 15 is connected to the side through hole 12.

[0045] By opening different No. 2 valves 13 and connecting the side through holes 12 in different directions, jet propulsion is achieved.

[0046] Among them, the control reversing component 14 includes a movable ring 141, an electric push rod 142 and a protective sleeve 143. The movable ring 141 is movably sleeved on the outer side of the isolation ring 7. The electric push rod 142 is located above the middle frame 3. The movable end of the electric push rod 142 passes through the middle frame 3 and is fixedly connected to the movable ring 141. The protective sleeve 143 is fixed on the top of the middle frame 3 and sleeved on the outer side of the electric push rod 142. A connecting hole is opened on the outer surface of the middle frame 3, and the connecting hole is connected to the connecting pipe 4. The connecting hole is located above the No. 1 pipe 62. The connecting hole and the outlet end of the No. 1 pipe 62 are both located on the movable path of the movable ring 141.

[0047] The control reversing assembly 14 controls the movement of the movable ring 141 to control the outlet direction of the No. 1 pipe 62, and realizes inflation when it is introduced into the connecting pipe 4, and performs unidirectional pushing when it is introduced into the side through hole 12.

[0048] The working principle and use process of the present invention are as follows: when in use, when it is necessary to throw it near the person who falls into the water, a small amount of ventilation is maintained inside the airbag cover assembly 5 in the initial state. At this time, the volume of the strong flotation device is small, and the strong flotation device is rotated and thrown near the person who falls into the water. The strong flotation device floats near the person who falls into the water, and the air supply assembly 6 is remotely started. As the air pump 61 is started, the air pump 61 draws gas toward the inside of the float suction assembly 9 through the No. 2 pipe 63 and the top sleeve 8, so that the air pressure inside the hose 95 is reduced, so that the pressure valve 96 is opened, and the ambient air is sucked in through the pressure valve 96, the hose 95, the top sleeve 8 and the No. 2 pipe 63, and is input into the annular space surrounded by the middle frame 3 and the isolation ring 7 through the No. 1 pipe 62, and is input into each connection The air supply assembly 6 is started again, so that when the air supply assembly 6 is immersed in the water, the air supply assembly 6 can use the floating independent float 91 to complete the air suction on the water surface, and the air supply assembly 6 can be completely lifted up by the floating independent float 91. The air is input into the airbag sleeve 52, so that the airbag sleeve 52 is quickly further filled with gas and the buoyancy is increased, and then the No. 1 valve 11 is further opened, so that the gas introduced is further passed into the strong flotation airbag 10 through the No. 1 valve 11, so that the hidden and contracted strong flotation airbag 10 is quickly inflated when the strong flotation device is immersed in water, and the buoyancy of the strong flotation device is further increased and floats; when the throwing position deviates, the control reversing component 14 is started, so that the electric push rod 142 drives the movable ring 141 to move upward along the outer side of the isolation ring 7, so that the isolation ring 7 blocks the connecting hole connected to the connecting pipe 4, so that the opening of the No. 2 valve 13 is connected to the No. 2 pipe 63, and the strong flotation device and the person who falls into the water The position and direction of the remote attack The No. 2 valve 13 in the corresponding direction of the side through hole 12 is opened, so that the air supply component 6 sucks the gas and passes it into the corresponding No. 2 valve 13, and then the air flow is input into the corresponding jet push pipe 15. As the gas sucked in and pressurized and pumped out is ejected along the jet push pipe 15, the strong flotation device floating on the water surface is pushed to move toward the person who falls into the water, completing the position calibration; when there are multiple people who fall into the water, the person who is rescued by the strong flotation device and sitting on the strong flotation device grabs the float in the float suction component 9, and further pulls out the pipeline hidden in the fixed frame 93, and takes out the float and throws it to other nearby people who fall into the water, so that other people who fall into the water can be further rescued by grabbing the thrown float, completing the rescue of multiple people with a single set of strong flotation devices.
