Description

Technical Field

[0001] This invention belongs to the field of water emergency rescue technology, specifically relating to a life-saving buoy with a self-generated light signal. Background Technology

[0002] In current technology, the mainstream emergency rescue equipment for water disasters such as shipwrecks is lifebuoys or life jackets. Life jackets are worn for prolonged floating, while lifebuoys are thrown to the person in the water for temporary grip. However, both lifebuoys and life jackets can only rescue one person at a time and are suitable for near-shore rescues. In distant water disasters, there is a certain amount of time from the occurrence of the disaster to the rescue. Existing lifebuoys and life jackets cannot store supplies and can only keep the user floating on the water. If the user lacks supplies for a long time, rescue supplies cannot be provided, which reduces the success rate of the rescue. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a multi-person life-saving float that can carry supplies.

[0004] The technical solution adopted to solve the above technical problems is: a life-saving buoy with self-generated light signal, including a storage buoy for storing supplies. The storage buoy is hemispherical, and a bottom sealing plate for sealing is fixedly connected to the bottom of the storage buoy by bolts and nuts.

[0005] The above technical solution, by setting up a hemispherical storage buoy, can provide a large internal space for storing emergency rescue supplies, such as drinking water, compressed food, first aid kits, and signal flares, meeting the basic survival needs of people who have fallen into the water while waiting for rescue. The bottom sealing plate is fixedly connected to the storage buoy with bolts and nuts, ensuring good sealing of the storage space and effectively preventing external water from entering the storage buoy, protecting the stored supplies from moisture and damage. This structural design makes the rescue buoy not only have the floating function of traditional rescue equipment, but also adds the key survival guarantee function of material storage, improving the survival probability and rescue success rate of people who have fallen into the water in remote water disasters.

[0006] A movable handle is provided above the storage buoy. A light-emitting acrylic is embedded and fixedly connected to the upper surface of the movable handle, and an LED light strip for providing a light source is bonded to the bottom of the light-emitting acrylic. Several evenly distributed independent buoys are provided at the bottom edge of the bottom sealing plate. A push-type generator is fixedly connected to the upper surface of the edge of the storage buoy at the position of the independent buoy.

[0007] Through the above technical solution, the movable handle facilitates the handling and movement of the life-saving buoy, making it easier for rescuers or people in the water to operate. The LED light strip bonded to the bottom of the luminous acrylic emits a conspicuous light signal, greatly improving the visibility of the life-saving buoy at night or in low-visibility environments, helping rescuers quickly locate the target. Several evenly distributed independent buoys on the bottom edge of the bottom sealing plate allow more people to lie on them, rescuing more people. The push-button generator, fixedly connected to the edge of the storage buoy at the position of the independent buoy, provides a sustainable power source for the LED light strip. When a person in the water lies on the surface of the independent buoy, the tilting column swings relative to the bottom sealing plate due to the action of waves, buoyancy, and weight deviation. The swinging column repeatedly squeezes the push-button generator, generating electricity that directly powers the LED light strip without relying on an external power source or disposable batteries. This ensures that the light signal can work stably and continuously in emergencies, solving the problem of insufficient signal indication capability of traditional life-saving equipment in the absence of power.

[0008] A stable upright marker is provided at the center of the bottom sealing plate.

[0009] The above technical solution effectively improves the overall buoyancy of the equipment after the stable anchor is inflated, and the conical stable anchor makes the equipment more stable.

[0010] Furthermore, a number of evenly distributed conductive connecting posts are fixedly connected to the lower surface of the movable grip. The power output terminal of the push-button generator is connected to the power input terminal of the LED light strip through a wire, and the wire passes through the storage float and the conductive connecting posts and extends into the movable grip.

[0011] Through the above technical solution, the conductive connecting post not only serves as a structural support connecting the moving handle and the storage buoy, but also provides a stable channel for power transmission between the push-button generator and the LED light strip. The design of the wire passing through the storage buoy and extending into the moving handle makes the circuit connection concealed and protected, effectively avoiding circuit failures caused by accidental pulling, wear, or corrosion of the wire in the water. This ensures the reliability and safety of power transmission from the generator to the light source, thereby guaranteeing that the LED light strip can continuously and stably emit light in complex water environments, providing a stable guarantee for rescue indication.

[0012] Furthermore, a material cover for retrieving materials is provided on the outer side of the storage buoy.

[0013] Through the above technical solution, the provision cover provides a convenient channel for accessing the supplies inside the storage buoy. When a person who has fallen into the water needs to obtain the stored drinking water, food, or first-aid supplies, they can quickly access them simply by opening the provision cover, without the need for complex disassembly of the entire buoy structure. This greatly improves the efficiency of obtaining emergency supplies. At the same time, the provision cover and the storage buoy are designed with a seal, which can effectively prevent external water from seeping into the storage space when the buoy is floating normally, ensuring that the internal supplies remain dry and intact. This convenient access method and reliable sealing performance make the life-saving buoy more practical and efficient in providing the function of storing supplies, ensuring that a person who has fallen into the water can obtain the necessary supplies in a timely manner and maintain vital signs.

[0014] Furthermore, the bottom sealing plate has several evenly distributed flipping grooves on its lower surface, and a flipping column is rotatably connected to each flipping groove. The flipping column is fixedly connected to an independent buoy, and an independent handle is fixedly connected to the outer side of the independent buoy. A soft elastic pad made of rubber is fixedly connected to the top wall of the flipping groove, and a hook groove is formed on the surface of the flipping column.

[0015] Through the above technical solution, the rotating connection structure between the tilting trough and the tilting column allows the independent buoy to tilt relative to the bottom sealing plate. When the rescue buoy is not in use or needs to be stored, the independent buoy can tilt upwards and fit under the bottom sealing plate, reducing the overall volume and facilitating transportation and storage. When used in the water, the independent buoy can tilt and unfold to form a ring support structure around the storage buoy, providing a gripping and prone position for multiple people in the water, effectively expanding rescue capacity. The independent handle provides a stable gripping point for people in the water, preventing them from slipping under the impact of waves and improving safety. The soft rubber elastic pad on the top wall of the tilting trough causes the tilting column to tilt when it is no longer fixed. The hook groove on the surface of the tilting column cooperates with the subsequent limiting hook to lock the independent buoy in the folded state, ensuring that space is effectively saved when not in use.

[0016] Furthermore, an airbag is fixedly connected through the center of the bottom sealing plate, and the stabilizing marker is folded and stored inside the airbag. A ring-shaped reaction chamber is fixedly connected to the upper surface of the bottom sealing plate. Sodium peroxide is placed inside the reaction chamber, and the upper surface of the reaction chamber is connected to the stabilizing marker pipe through an expansion gas pipe.

[0017] Through the above technical solution, the airbag provides storage space for the stabilizing buoy, allowing it to be folded and stored when not in use, effectively reducing the overall volume of the life-saving buoy and facilitating transportation and storage. The sodium peroxide placed inside the annular reaction chamber undergoes a chemical reaction with water to generate oxygen. The generated oxygen is transported to the stabilizing buoy through an expansion tube, causing the stabilizing buoy to inflate and extend out of the airbag. After inflation, the stabilizing buoy not only significantly improves the overall buoyancy of the device and enhances its stability in water, but this method of using a chemical reaction to generate gas to inflate the stabilizing buoy eliminates the need for additional inflation equipment, ensuring reliable deployment of the stabilizing buoy in emergency situations.

[0018] Furthermore, a reaction hole is provided between the bottom of the bottom sealing plate and the bottom of the reaction chamber. A guide rod is fixedly connected to the top wall of the reaction chamber directly above the reaction hole. The guide rod extends to the reaction hole, and a float is slidably connected to the guide rod above the reaction hole.

[0019] Through the above technical solution, the reaction hole provides a channel for external water to enter the reaction tank. When the lifebuoy is put into the water, water can enter the reaction tank through the reaction hole and react chemically with sodium peroxide to produce oxygen. The guide rod extends from the top wall of the reaction tank to the reaction hole, providing stable guidance for the up-and-down sliding of the float, ensuring that the float can accurately block or open the reaction hole. In the initial state, the float is located below the guide rod under its own weight, blocking the reaction hole and preventing the sodium peroxide in the reaction tank from reacting due to accidental contact with water when the lifebuoy is not in the water. When the lifebuoy is put into the water, the buoyancy of the external water acts on the float, causing the float to slide upward along the guide rod, thereby opening the reaction hole and allowing water to enter the reaction tank to start the chemical reaction. As the reaction proceeds, when the sodium peroxide in the reaction tank is consumed to a certain extent or the generated gas pressure reaches a certain threshold, the float falls again under the action of internal pressure to block the reaction hole, avoiding over-reaction or gas leakage and effectively maintaining pressure.

[0020] Furthermore, an isolation pad is fixedly connected between the top of the outer wall of the bottom sealing plate and the inner wall of the storage buoy. A support air cylinder is fixedly connected to the inner wall of the storage buoy at the independent buoy position and below the isolation pad. The outer wall of the support air cylinder is connected to the reaction chamber through an expansion air pipe, and the expansion air pipe is fixedly connected to the isolation pad. A movable piston is slidably connected to the inner wall of the support air cylinder. A linkage plate is fixedly connected to the outer end of the movable piston of the support air cylinder. A support spring is fixedly connected between the inner end of the movable piston of the support air cylinder and the inner wall of the support air cylinder.

[0021] Through the above technical solution, the isolation pad is positioned between the top of the outer wall of the bottom sealing plate and the inner wall of the storage buoy, providing excellent sealing and isolation. This effectively prevents water from entering the equipment through the control chute. The support air cylinder, located at the independent buoy position and fixedly connected below the isolation pad, is a key component for the automatic deployment of the independent buoy. The support air cylinder is connected to the reaction chamber pipeline via an expansion air pipe, which passes through and is fixed to the isolation pad. This design allows some of the oxygen produced by the chemical reaction inside the reaction chamber to be transported to the inside of the support air cylinder through the expansion air pipe. When the oxygen enters the support air cylinder, it pushes the inner wall... The sliding piston overcomes the elastic force of the support spring and moves to the outside of the support cylinder. The linkage plate fixedly connected to the end of the sliding piston outside the support cylinder moves synchronously with the movement of the sliding piston, thereby driving the I-shaped slider fixedly connected to it to slide in the control groove, ultimately releasing the engagement state of the limit hook and the hook groove. The support spring fixedly connected between the end of the sliding piston inside the support cylinder and the inner wall of the support cylinder can pull the sliding piston back to the initial position when the air pressure inside the support cylinder decreases or is lost, preparing for the next action and ensuring the reset capability and reliability of the entire mechanical structure.

[0022] Furthermore, a control groove is provided through the lower surface of the bottom sealing plate below the supporting air cylinder. An I-shaped slider is slidably connected to the control groove. The top of the I-shaped slider is fixedly connected to the linkage plate, and a limit hook is fixedly connected to the bottom of the I-shaped slider, and the limit hook engages with the hook groove.

[0023] Through the above technical solution, the control groove provides a precise guide track for the sliding of the I-beam slider, ensuring its stable and smooth up-and-down movement. The top of the I-beam slider is fixedly connected to the linkage plate, allowing the linear motion of the moving piston inside the support cylinder to be transmitted to the I-beam slider through the linkage plate, thereby driving it to slide within the control groove. When gas is generated in the reaction chamber and enters the support cylinder through the expansion pipe, the moving piston is pushed outward, and the linkage plate subsequently drives the I-beam slider to slide upward within the control groove. At this time, the limiting hook fixedly connected to the bottom of the I-beam slider also moves upward simultaneously, thereby releasing its engagement with the hook groove on the surface of the flip column. Once the limiting hook disengages from the hook groove, the originally locked flipping column, under the elastic force of the soft rubber elastic pad on the top wall of the flipping groove, causes the independent buoy to flip downward and unfold, forming a support structure for the person in the water to grab and lie down. Conversely, when it is necessary to retract the independent buoy, the independent buoy can be manually flipped inward, so that the hook groove on the flipping column can engage with the limiting hook again. This design, which uses gas pressure to drive the mechanical structure to achieve limiting and unlocking, cleverly converts chemical reaction energy into mechanical energy, realizing the automatic unfolding of the independent buoy without manual intervention, greatly improving the rapid response capability and ease of use of the life-saving buoy in emergency situations.

[0024] The beneficial effects of the present invention are as follows: (1) Through the collaborative design of the press-type generator and the LED light strip, the self-generated light signal function is realized. It does not need to rely on external power or disposable batteries, ensuring that the light signal is stable and lasting in emergency situations, effectively solving the problem of insufficient signal indication when there is no power in traditional life-saving equipment; (2) The integrated storage buoy and material cover structure provides reliable sealing protection for internal emergency materials while realizing convenient access to materials, improving the efficiency of people who have fallen into the water to obtain drinking water, food and first aid supplies, and ensuring the maintenance of their vital signs; (3) The linkage mechanism of the reaction chamber, the stable buoy, and the supporting air cylinder is adopted. The oxygen is generated autonomously by the reaction of sodium peroxide with water. This not only drives the stable buoy to inflate and unfold to enhance buoyancy and stability, but also automatically unlocks the independent buoy through gas pressure, causing it to unfold downward to form a cone structure, making the equipment more stable. The independent buoys set around the perimeter effectively increase the rescue capacity. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] like Figure 1-7 As shown in the figure, this embodiment of a life-saving buoy with a self-generated light signal includes a storage buoy 1 for storing supplies. The storage buoy 1 is hemispherical, and a bottom sealing plate 7 for sealing is fixedly connected to the bottom of the storage buoy 1 by bolts and nuts. By setting the storage buoy 1 in a hemispherical shape, a large internal space can be provided for storing emergency rescue supplies, such as drinking water, compressed food, first-aid kits, and signal flares, meeting the basic survival needs of people who have fallen into the water while waiting for rescue. The bottom sealing plate 7 is fixedly connected to the storage buoy 1 by bolts and nuts, ensuring good sealing of the storage space and effectively preventing external water from entering the interior of the storage buoy 1, protecting the stored supplies from moisture and damage. This structural design allows the life-saving buoy to not only possess the floating function of traditional life-saving equipment but also add the crucial survival guarantee function of supply storage, improving the survival probability and rescue success rate of people who have fallen into the water in distant flood disasters.

[0029] The bottom sealing plate 7 has several evenly distributed flipping grooves 12 on its lower surface. A flipping column 10 is rotatably connected to each flipping groove 12, and the flipping column 10 is fixedly connected to an independent buoy 4. An independent handle 6 is fixedly connected to the outer side of the independent buoy 4. A soft elastic pad 26, made of rubber, is fixedly connected to the inner top wall of the flipping groove 12. A hook groove 15 is provided on the surface of the flipping column 10. This rotatable connection between the flipping groove 12 and the flipping column 10 allows the independent buoy 4 to flip relative to the bottom sealing plate 7. When the lifesaving buoy is not in use or needs to be stored, the independent buoy 4 can be flipped upwards and fitted under the bottom sealing plate 7, reducing the overall volume and facilitating transportation and storage. When deployed in the water, the independent buoy 4 can be flipped and unfolded to form a ring support structure around the storage buoy 1, providing a gripping and prone position for multiple people in the water, effectively expanding the rescue capacity. The independent handle 6 provides a stable gripping point for people in the water, preventing them from slipping under the impact of waves and improving the safety of use. The soft rubber elastic pad 26 on the inner top wall of the flipping groove 12 causes the flipping column 10 to flip when it is no longer fixed. The hook groove 15 on the surface of the flipping column 10 cooperates with the subsequent limiting hook 13 to lock the independent buoy 4 in the retracted state, ensuring that space can be effectively saved when not in use.

[0030] A control groove 22 is formed through the lower surface of the bottom sealing plate 7, located below the supporting gas cylinder 20. An I-beam slider 27 is slidably connected to the control groove 22. The top of the I-beam slider 27 is fixedly connected to the linkage plate 21, and the bottom of the I-beam slider 27 is fixedly connected to a limit hook 13, which engages with a hook groove 15. The control groove 22 provides a precise guide track for the sliding of the I-beam slider 27, ensuring stable and smooth up-and-down movement. The fixed connection between the top of the I-beam slider 27 and the linkage plate 21 allows the linear motion of the moving piston 23 inside the supporting gas cylinder 20 to be transmitted to the I-beam slider 27 via the linkage plate 21, thereby causing it to slide within the control groove 22. When gas is generated in the reaction chamber 17 and enters the supporting gas cylinder 20 through the expansion pipe 18, the moving piston 23 is pushed outward, and the linkage plate 21 subsequently moves the I-beam slider 27 within the control groove 22. As the slider slides upward within groove 22, the limiting hook 13, which is fixedly connected to the bottom of the I-shaped slider 27, also moves upward simultaneously, thereby releasing its engagement with the hook groove 15 on the surface of the flipping column 10. Once the limiting hook 13 disengages from the hook groove 15, the originally locked flipping column 10, under the elastic force of the soft rubber elastic pad 26 on the top wall of the flipping groove 12, drives the independent buoy 4 to flip downward and unfold, forming a support structure for the person in the water to grab and lie down. Conversely, when it is necessary to retract the independent buoy 4, the independent buoy 4 can be manually flipped inward, so that the hook groove 15 on the flipping column 10 engages with the limiting hook 13 again. This design, which uses gas pressure to drive the mechanical structure to achieve limiting and unlocking, cleverly converts chemical reaction energy into mechanical energy, realizing the automatic unfolding of the independent buoy 4 without manual intervention, greatly improving the rapid response capability and ease of use of the life-saving buoy in emergency situations.

[0031] A reaction hole 11 is formed between the bottom of the bottom sealing plate 7 and the bottom of the reaction tank 17. A guide rod 28 is fixedly connected to the top wall of the reaction tank 17 directly above the reaction hole 11. The guide rod 28 extends to the reaction hole 11 and is slidably connected to a float 29 above the reaction hole 11. The reaction hole 11 provides a channel for external water to enter the reaction tank 17. When the life buoy is put into the water, water can enter the interior of the reaction tank 17 through the reaction hole 11 and react with sodium peroxide to produce oxygen. The guide rod 28 extends from the top wall of the reaction tank 17 to the reaction hole 11, providing stable guidance for the up and down sliding of the float 29, ensuring that the float 29 can accurately align with the reaction hole 11. In the initial state, the float 29 is positioned below the guide rod 28 under its own weight, blocking the reaction hole 11. This prevents the sodium peroxide in the reaction tank 17 from reacting due to accidental contact with water when the life buoy is not in the water. When the life buoy is put into the water, the buoyancy of the external water acts on the float 29, causing it to slide upward along the guide rod 28, thereby opening the reaction hole 11 and allowing water to enter the reaction tank 17 to start the chemical reaction. As the reaction proceeds, when the sodium peroxide in the reaction tank 17 is consumed to a certain extent or the generated gas pressure reaches a certain threshold, the float 29 falls again under the action of internal pressure to block the reaction hole 11, preventing over-reaction or gas leakage and effectively maintaining pressure.

[0032] An airbag cylinder 14 is fixedly connected through the center of the bottom sealing plate 7, and the stabilizing buoy 8 is folded and stored inside the airbag cylinder 14. A ring-shaped reaction chamber 17 is fixedly connected to the upper surface of the bottom sealing plate 7. Sodium peroxide is placed inside the reaction chamber 17. The upper surface of the reaction chamber 17 is connected to the stabilizing buoy 8 through an expansion pipe 19. The airbag cylinder 14 provides storage space for the stabilizing buoy 8, allowing it to be folded and stored inside when not in use, effectively reducing the overall volume of the life-saving buoy and facilitating transportation and storage. The sodium peroxide placed inside the ring-shaped reaction chamber 17 undergoes a chemical reaction with water to generate oxygen. The generated oxygen is transported to the stabilizing buoy 8 through the expansion pipe 19, causing the stabilizing buoy 8 to inflate and extend out of the airbag cylinder 14. After inflation, the stabilizing buoy 8 not only significantly improves the overall buoyancy of the device and enhances its stability in water, but this method of using a chemical reaction to generate gas to inflate the stabilizing buoy 8 eliminates the need for additional inflation equipment, ensuring the reliable deployment of the stabilizing buoy 8 in emergency situations.

[0033] A supply cover 24 is provided on the outer side of the storage buoy 1 for accessing supplies. The supply cover 24 provides a convenient channel for accessing the supplies inside the storage buoy 1. When a person who has fallen into the water needs to obtain the stored drinking water, food, or first aid supplies, they can simply open the supply cover 24 to quickly retrieve them without having to disassemble the entire buoy structure. This greatly improves the efficiency of obtaining emergency supplies. At the same time, the supply cover 24 and the storage buoy 1 are sealed together, which can effectively prevent external water from seeping into the storage space when the buoy is floating normally, ensuring that the internal supplies are dry and intact. This convenient access method and reliable sealing performance make the life-saving buoy more practical and efficient in providing the function of storing supplies, ensuring that a person who has fallen into the water can obtain the necessary supplies in a timely manner and maintain vital signs.

[0034] A movable handle 3 is located above the storage buoy 1. A luminous acrylic strip 2 is inlaid and fixedly connected to the upper surface of the movable handle 3, and an LED light strip for providing a light source is adhered to the bottom of the luminous acrylic strip 2. Several evenly distributed independent buoys 4 are located at the bottom edge of the bottom sealing plate 7. A push-button generator 5 is fixedly connected to the upper surface of the edge of the storage buoy 1 at the location of the independent buoy 4. The movable handle 3 facilitates the handling and movement of the life buoy, making it convenient for rescuers or people in the water to operate it. The LED light strip adhered to the bottom of the luminous acrylic strip 2 can emit a conspicuous light signal, greatly improving the visibility of the life buoy at night or in low visibility environments, helping rescuers quickly locate the target position. The several evenly distributed independent buoys 4 are located at the bottom edge of the bottom sealing plate 7. The evenly distributed independent buoys 4 allow more people to lie on them, enabling the rescue of more people. The push-button generator 5, which is fixedly connected to the upper surface of the storage buoy 1 at the position of the independent buoy 4, provides a sustainable power source for the LED light strip. When a person who has fallen into the water lies on the surface of the independent buoy 4, the tilting column 10 swings relative to the bottom sealing plate 7 due to the action of waves, buoyancy, and weight deviation. The swinging column 10 can repeatedly squeeze the push-button generator 5, causing it to generate electricity. The generated electricity can directly power the LED light strip without relying on an external power source or disposable batteries, ensuring that the light signal can work stably and continuously in emergency situations. This solves the problem of insufficient signal indication capability of traditional lifesaving equipment in the absence of power.

[0035] Several evenly distributed conductive connecting posts 9 are fixedly connected to the lower surface of the movable handle 3. The power output terminal of the push-button generator 5 is connected to the power input terminal of the LED light strip via a wire. The wire passes through the storage buoy 1 and the conductive connecting posts 9 and extends into the movable handle 3. The conductive connecting posts 9 not only serve as structural supports connecting the movable handle 3 and the storage buoy 1, but also provide a stable channel for power transmission between the push-button generator 5 and the LED light strip. The design of the wire passing through the storage buoy 1 and the conductive connecting posts 9 and extending into the movable handle 3 makes the circuit connection concealed and protected, effectively avoiding circuit failures caused by accidental pulling, wear, or corrosion of the wire in the water. This ensures the reliability and safety of power transmission from the generator to the light source, thereby ensuring that the LED light strip can continuously and stably emit light in complex water environments, providing a stable guarantee for rescue indication.

[0036] An isolation pad 25 is fixedly connected between the top of the outer wall of the bottom sealing plate 7 and the inner wall of the storage buoy 1. A support air cylinder 20 is fixedly connected to the inner wall of the storage buoy 1 at the position of the independent buoy 4 and below the isolation pad 25. The outer wall of the support air cylinder 20 is connected to the reaction chamber 17 through an expansion air pipe 18, and the expansion air pipe 18 is fixedly connected to the isolation pad 25. A moving piston 23 is slidably connected to the inner wall of the support air cylinder 20. A linkage plate 21 is fixedly connected to one end of the moving piston 23 outside the support air cylinder 20. Piston 23 is located inside the support cylinder 20, with one end fixedly connected to the inner wall of the support cylinder 20 by a support spring 16. Isolation pad 25 is positioned between the top of the outer wall of the bottom sealing disc 7 and the inner wall of the storage buoy 1, providing good sealing and isolation, effectively preventing water from entering the equipment through the control chute 22. The support cylinder 20, located on the inner wall of the storage buoy 1 at the position of the independent buoy 4 and fixedly connected below the isolation pad 25, is a key actuator for the automatic deployment of the independent buoy 4. The support cylinder 20 expands through an air pipe... The expansion pipe 18 is connected to the reaction chamber 17 and passes through and is fixed to the isolation pad 25. This design allows some of the oxygen produced by the chemical reaction in the reaction chamber 17 to be transported to the inside of the support cylinder 20 through the expansion pipe 18. When the oxygen enters the support cylinder 20, it will push the movable piston 23, which is slidably connected to the inner wall, to overcome the elastic force of the support spring 16 and move to the outside of the support cylinder 20. The linkage plate 21, which is fixedly connected to one end of the movable piston 23 outside the support cylinder 20, will move synchronously with the movement of the movable piston 23, thereby driving the I-shaped slider 27, which is fixedly connected to it, to slide in the control groove 22, and finally realize the release of the engagement state between the limit hook 13 and the hook groove 15. The support spring 16, which is fixedly connected between the one end of the movable piston 23 inside the support cylinder 20 and the inner wall of the support cylinder 20, can pull the movable piston 23 back to the initial position when the air pressure in the support cylinder 20 decreases or loses air pressure, so as to prepare for the next action and ensure the reset capability and reliability of the entire mechanical structure.

[0037] A stabilizing anchor 8 is installed in the middle of the bottom sealing plate 7. After the stabilizing anchor 8 is inflated, it can effectively improve the overall buoyancy of the equipment, and the conical stabilizing anchor 8 makes the equipment more stable.

[0038] The working principle of this embodiment is as follows: When the life buoy is put into the water, the external water acts on the float 29 through the reaction hole 11. Under the action of buoyancy, the float 29 slides upward along the guide rod 28, opening the reaction hole 11. Water then enters the reaction tank 17 and reacts chemically with the sodium peroxide inside to generate oxygen. Part of the generated oxygen is transported to the stabilizing buoy 8 through the expansion pipe 19, causing it to inflate and extend out of the air bladder 14. The conical stabilizing buoy 8 not only significantly improves the overall buoyancy of the equipment but also enhances its stability in the water, effectively preventing the life buoy from violently shaking or capsizing in the waves. At the same time, another part of the oxygen enters the support air cylinder 20 through the expansion pipe 18, pushing the moving piston 23 to move outward against the elastic force of the support spring 16. The linkage plate 21 then drives the I-shaped slider 27 to slide upward in the control groove 22, causing the limit hook 13 to disengage from the hook groove 15 on the flip column 10. At this time, under the elastic force of the soft rubber elastic pad 26 on the top wall of the tilting groove 12, the tilting column 10 drives the independent buoy 4 to tilt downwards and unfold, forming a ring support structure around the storage buoy 1. The independent handle 6 provides a stable grip point for the person in the water. When the person in the water lies on the independent buoy 4, the weight of the body, buoyancy, and the wave action will cause the tilting column 10 to swing relative to the bottom sealing plate 7, repeatedly squeezing the press-type generator 5. The electrical energy generated by the generator is transmitted to the LED light strip in the movable handle 3 through the wire passing through the storage buoy 1 and the conductive connecting column 9, illuminating the luminous acrylic 2 and emitting a conspicuous light signal. The person in the water can open the material cover 24 to retrieve the emergency supplies stored in the storage buoy 1. When the sodium peroxide in the reaction chamber 17 is consumed to a certain extent or the gas pressure reaches the threshold, the float 29 falls under the internal pressure to block the reaction hole 11, preventing over-reaction and gas leakage. If it is necessary to retract the independent float 4, it can be manually flipped inward to re-engage the hook groove 15 with the limit hook 13, thus completing the storage.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
