Description

Technical Field

[0001] This invention relates to the field of maritime rescue equipment technology, and in particular to an integrated rescue system for people injured in the water at sea. Background Technology

[0002] In the field of drone-based maritime rescue, the main method is to airdrop lifebuoys or life jackets to provide buoyancy for people in the water. However, this method of airdropping lifebuoys or life jackets has the following drawbacks: 1. The current method of directly airdropping lifebuoys or life jackets without any protective storage device means that the lifebuoys or life jackets are easily damaged when they fall directly onto the water. 2. Lifebuoys or life jackets are not suitable for people with injuries, such as spinal injuries or fractures. 3. People wearing lifebuoys or life jackets are still submerged in water, and due to the low sea temperature, they are prone to hypothermia while waiting for rescue. 4. Sea conditions vary, and people wearing lifebuoys or life jackets are still prone to drowning in rough seas. 5. If the person in the water is injured, secondary injuries can easily occur during the repatriation process. In response to the shortcomings of current maritime rescue methods, this invention designs an integrated rescue system suitable for injured persons who have fallen into the water at sea. Summary of the Invention

[0003] This invention addresses the problems and shortcomings of existing technologies by providing an integrated rescue system for people injured in the water at sea.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] This invention provides an integrated rescue system for drowning victims at sea, characterized by comprising a protective device, a maritime rescue device, and a delivery system. The protective device includes a protective shell, a shell hoisting mechanism, and a shell zipper mechanism mounted on the protective shell. The protective shell houses the folded maritime rescue device. The maritime rescue device includes a foldable airbag mechanism, a foldable stretcher mechanism, a stretcher hoisting mechanism, and a positioning system. The foldable stretcher mechanism is placed on top of the foldable airbag mechanism and fixedly installed within its stretcher receiving cavity. The stretcher hoisting mechanism and positioning system are mounted on the foldable stretcher mechanism. The delivery system includes a drone and a delivery device at its base; the drone's delivery device is equipped with the shell hoisting mechanism for... For the hoisting of the protective device with built-in maritime rescue equipment, the drone is used to search and locate the position of the injured person in the water and then deploy the protective device to a certain position away from the injured person; the outer shell zipper mechanism is unlocked by the rescuer to open the protective device and release the maritime rescue equipment, the foldable airbag mechanism is inflated and deployed, and the foldable stretcher mechanism is spliced ​​and deployed. With the help of the rescuer, the injured person in the water lies on the deployed foldable stretcher mechanism to wait for rescue; the positioning system is used to report the location to the rescue command center in real time to guide the search and rescue personnel to rescue; the stretcher hoisting mechanism is used to separate the foldable airbag mechanism and the foldable stretcher mechanism under the lifting action of the rescue helicopter, and only the foldable stretcher mechanism with the injured person in the water is hoisted and fixed.

[0006] The positive and progressive effects of this invention are as follows: This invention designs a protective device, which includes a protective shell, a shell hoisting mechanism, and a shell zipper mechanism. The designed protective shell is used to house and protect the marine rescue device. The designed shell hoisting mechanism is used to facilitate the hoisting of the protective device containing the marine rescue device. The designed shell zipper mechanism is used to quickly open the protective device and realize the rapid release of the marine rescue device.

[0007] This invention designs a stretcher-type maritime rescue device, suitable for people injured at sea. It allows people injured at sea to lie on the stretcher of the maritime rescue device and not be in the water for a long time while waiting for rescue and transfer, which greatly reduces the possibility of hypothermia. At this time, the maritime rescue device is at an anti-drowning tilt angle, which helps to extend the waiting time for maritime rescue.

[0008] This invention is easy to disassemble. During hoisting and transportation, the foldable airbag mechanism and the foldable stretcher mechanism can be quickly detached, allowing the injured person lying on the unfolded stretcher to be transported together with the stretcher. This can effectively prevent secondary injury to the injured person during transportation, effectively prevent hypothermia and drowning, and extend the waiting time for rescue at sea.

[0022] In this embodiment, the storage pull rope 23, the front storage cover 24, and the rear storage cover 25 are used to store the front lateral lifting rope 21 and the rear lateral lifting rope 22 when not in use. The middle cover 26 is used to store the storage pull rope 23. When lateral lifting ropes are needed for lifting, the upper cover 12 is placed below and the lower shell 11 is placed above. The front lateral lifting rope 21 and the rear lateral lifting rope 22 are pulled up, so that the remaining 212 of the front lateral lifting rope 21 and the remaining 221 of the rear lateral lifting rope 22 located inside the lower shell 11 are extracted. The front lateral lifting rope 21 and the rear lateral lifting rope 22 are attached to the delivery system to achieve the lifting of the protective device with the built-in marine rescue device (see...). Figure 34 This completes the pre-lifting preparation work. When it is not necessary to use the front horizontal lifting rope 21 and the rear horizontal lifting rope 22 for lifting, the bottom cover 211 can be opened and the storage pull rope 23 can be pulled back into the front storage cover 24 and the rear storage cover 25. The storage pull rope 23 is stored between the middle cover 26 and the bottom cover 211.

[0023] The outer shell hoisting mechanism 20 also includes a longitudinal hoisting mechanism, which includes a longitudinal lifting ring 213 fixed to at least one side of the lower shell 11.

[0038] In this embodiment, pulling the first inflation rope 1041 opens the first inflation quick-release valve 1035, and the gas in the gas cylinder 1032 passes through the first connecting pipe 1033 and the first inflation quick-release valve 1035 in sequence to inflate the head airbag 1011 and the long auxiliary airbag 1013. The head airbag 1011 and the long auxiliary airbag 1013 are in an unfolded state, which drives the upper and lower parts of the foldable stretcher mechanism in a folded state to unfold. Then, pulling the second inflation rope 1042 opens the second inflation quick-release valve 1036, and the gas in the gas cylinder 1032 passes through the second connecting pipe 1034 and the second inflation quick-release valve 1036 in sequence to inflate the tail airbag 1012. The tail airbag 1012 is in an unfolded state, thereby realizing the sequential inflation of the airbag body to adjust the posture of the airbag body in the water, so that it is at about 45° with the water surface, which facilitates the transfer of the drowning victim from the water and fixation to the foldable stretcher mechanism.

[0039] The foldable stretcher mechanism includes a stretcher body 201 formed by splicing a first stretcher 2011 and a second stretcher 2012 together with two sleeves 2013; a backplate body 202 formed by splicing a first backplate 2021 and a second backplate 2022; and a soft bottom plate body 203 formed by splicing a first soft bottom plate 2031 and a second soft bottom plate 2032 for the injured person to lie on.

Magnetic buckles 504 and hook-and-loop fasteners 505 are fixed at intervals at the connection points on the other side of the first sunshade cloth 5011 and the second sunshade cloth 5012. Eight hook-and-loop fasteners for attaching to the stretcher hoisting mechanism are also arranged on the inner walls of the first sunshade cloth 5011 and the second sunshade cloth 5012. The eight hook-and-loop fasteners are used to attach the slings 301 in the stretcher hoisting mechanism to facilitate the rapid hoisting and detachment of the rescue stretcher.

[0048] Among them, such as Figure 34 As shown, the delivery system includes a drone 60 and a delivery device 61 at its bottom.

[0049] The rescue scenario is as follows: Suppose two people fall into the water, one of whom is injured and unable to move, serving as the injured person, while the other is able to move independently and serves as the rescuer. The rescue command center learns that it will take some time from when the injured person falls into the water to when they are rescued. Therefore, a drone is first used to hoist a marine rescue device to the area where the injured person fell into the water and deploy the device to extend the time the injured person has to wait for rescue. Under this premise, the rescue operation will commence.

[0050] The entire operation process can be divided into six parts: positioning and deployment, device deployment and securing of the injured person who fell into the water, full device coverage, on-site observation, out-of-water transfer, and subsequent rescue and treatment.

[0051] 1) Positioning and Deployment: The rescue command center dispatches drone operators to pull up the front horizontal lifting rope 21 and rear horizontal lifting rope 22, which are in a retracted state, from the maritime rescue device. This allows the remaining 212 of the front horizontal lifting rope 21 and the remaining 221 of the rear horizontal lifting rope 22, located inside the protective shell 10, to be extracted. The front horizontal lifting rope 21 and rear horizontal lifting rope 22 are then attached to the hooks at the bottom of the deployer, thus lifting the protective device containing the maritime rescue device. The drone is now ready for deployment. Subsequently, the drone, carrying the maritime rescue device, takes off and arrives at the area where the injured person fell into the water. The drone searches for the injured person's location, locks onto the injured person, and transmits images to the remote command terminal. Following the command terminal's instructions, the drone deploys the device; upon receiving the command, the hooks at the bottom of the deployer separate, and the maritime rescue device is dropped approximately 20 meters from the injured person.

[0052] 2) Deployment of equipment and securing of injured persons who have fallen into the water.

[0053] Device deployment: Rescuers pull the zipper unlocking handle 34, which drives the left zipper 313 and right zipper 323 connected to the pull rope 33 and located at both ends, unlocking the left zipper 313 and right zipper 323 and opening the protective device to release the marine rescue device inside. Rescuers pull down the first inflation rope 1041 (the first inflation rope is red), which connects the first inflation quick-release valve 1035, which is connected to the two high-pressure gas cylinders 1032. The gas inside the two high-pressure gas cylinders 1032 flows sequentially through the first connecting pipe 1033 and the first inflation quick-release valve 1035 to inflate the head airbag 1011 and the long auxiliary airbag 1013. The head airbag 1011 and the long auxiliary airbag 1013 inflate, thereby causing the upper and lower parts of the foldable stretcher to unfold, tilting the rescue device at about 45° to the water surface. At this point, the upper airbag is inflated. After completion, the rescuers slide the sleeve 2013 connected to the first stretcher 2011 according to the direction of the sleeve limiting notch 20132 and attach it to the second stretcher 2012, thus completing the unfolding and fixing of the upper and lower parts of the foldable stretcher mechanism.

[0054] Immobilization of drowning victims: Rescuers grab the drowning victim with one hand and the marine rescue device with the other. Slowly push the drowning victim onto the upper part of the rescue device (i.e., the position of the inflated head airbag 1011), and first use the head and neck immobilizer 2034 and the chest and waist immobilizer 2035 to stabilize the head, neck, and chest. After securing the device, rescuers pull down the second inflation rope 1042 (the second inflation rope is blue), which connects the second inflation quick-release valve 1036, which is connected to the remaining two high-pressure gas cylinders 1032. The gas inside the remaining two high-pressure gas cylinders 1032 flows sequentially through the second connecting pipe 1034 and the second inflation quick-release valve 1036 to inflate the tail airbag 1012. The tail airbag 1012 inflates, adjusting the maritime rescue device from an inclined position to a horizontal position, allowing it to float upright on the water. This ensures the injured person is fully afloat and in contact with the rescue device. At this point, the leg fixation device 2036 and foot fixation device 2037 are used to secure the lower body of the injured person, completing the fixation process.

[0055] 3) Full Coverage of the Device: Rescuers pull the main body of the sunshade 501, causing the magnetic snaps 504 and hook-and-loop fasteners 505 connected to the main body of the sunshade 501 to separate. Under the action of the sunshade supports located at both ends, the main body of the sunshade 501 is supported from both sides of the airbag body 101 and connected by the magnetic snaps 504 and hook-and-loop fasteners 505, thus achieving full coverage of the rescue device, waiting for the rescue to be hoisted. The positioning system 40 is used to report the location to the rescue command center in real time to guide the search and rescue personnel to the rescue.

[0056] 4) In-situ observation

[0057] Helicopter rescue: After the helicopter arrives at the area where the injured person is in the water, it will hover at a safe altitude to observe the injured person and the surrounding situation, and formulate a winch descent and hoisting plan according to the situation.

[0058] Vessel rescue: Rescue boats or rescue dinghies go to the area where the injured person is in the water. After arriving, they wait in a safe area, observe the injured person, equipment and the surrounding situation, and determine a rescue plan based on the actual situation.

[0059] 5) Off-water transfer

[0060] Helicopter Rescue: Rescuers open the sunshade body 501 and attach the two lifting rings 303 of the stretcher hoisting mechanism, which are fastened to the inside of the sunshade with hooks and loops, to the helicopter's rescue hoisting gear. The hoisting operation is now ready. After signaling the helicopter to connect, the winch descends to begin hoisting. As the helicopter lifts the stretcher hoisting mechanism, the lifting rings 303 taut the four slings 301 under the upward lifting action of the rescue helicopter. As the slings 301 are gradually pulled upward, the connecting straps 204 connected to them gradually taut, driving the indexing pin 2014. This causes the pin inside the indexing pin 2014 to overcome the spring preload and pull upward, thereby detaching the stretcher connecting ring 1052 from the pin. This achieves one-click detachment of the foldable stretcher mechanism and the foldable airbag mechanism, allowing only the foldable stretcher mechanism containing the drowning victim to be hoisted and secured.

[0061] Boat rescue: Boat rescuers release the hook, and rescuers assist the hook to the reserved pull rope at the edge of the airbag, drag the rescue device to the edge of the rescue boat, pull the indexing pin 2014 to separate the foldable stretcher 20 and the foldable airbag 10, and then use the docking slides 2026 at both ends of the foldable stretcher 20 to lift the stretcher onto the rescue boat and return it to the mother ship for treatment.

[0062] 6) Subsequent treatment: Helicopters or rescue ships transport the injured to hospital ships or other maritime rescue platforms. Medical personnel use the docking slides at both ends of the foldable stretcher mechanism to lift the stretcher onto a flatbed for further treatment.
