[0032] An embodiment of the present invention:

[0033] Referring to Figures 1 - 7 , the present invention provides a water emergency rescue device, including an air cushion 10. The air cushion 10 is formed by bonding two pieces of fabrics made of TPU material. On both sides of the air cushion 10 parallel to the length direction, a first hollow rod 20 and a second hollow rod 21 are respectively arranged. The air cushion 10 can be wound around the outer periphery of the first hollow rod 20. The air cushion 10 can be fixed between the first hollow rod 20 and the second hollow rod 21. Two connecting rods 30 spanning the upper side of the air cushion 10 are detachably connected between the first hollow rod 20 and the second hollow rod 21. A gas storage cylinder 50 is fixed inside the first hollow rod 20. The gas storage cylinder 50 stores liquid high-pressure carbon dioxide gas. The volume of these gases after expansion is sufficient for the air cushion 10 to expand to be taut. The gas storage cylinder 50 inflates the air cushion 10 through an air delivery component.

[0034] Referring to Figure 1 , first, a part with the same cross-section as the drain port 101 is cut off from the two TPU fabrics, and then a fabric made of the same material as the air cushion 10 is made into a circular ring and bonded between the two TPU fabrics along the cut-off part, so as to form two drain ports 101 that penetrate through the air cushion 10 along its thickness. The inside of the air cushion 10 is hollow.

[0035] Referring to Figure 3 , two rod sleeves 22 are rotatably connected to the outer periphery of the first hollow rod 20. Two connecting parts 12 covering the outer periphery of the rod sleeves 22 are fixed to the edge of the air cushion 10 close to the first hollow rod 20.

[0036] Referring to Figure 2, a hanging part 211 is provided on the outer periphery of the second hollow rod 21, which is recessed radially inward along it. A plurality of movable buckles 11 are fixed on the edge of the air cushion 10 close to the second hollow rod 21. The movable buckles 11 can be buckled in the hanging part 211. The inner diameter of the movable buckle 11 is smaller than the outer diameter of the second hollow rod 21. One end of the movable buckle 11 is adhered to the outer surface of the air cushion 10 by an adhesive.

[0037] Refer to Figure 1 , the connecting rod 30 is composed of a horizontal part located above the air cushion 10 and vertical parts located on both sides of the air cushion 10. Buckles 31 are fixed at the ends of the vertical parts of the connecting rod 30. The lower end of the buckle 31 is open, and the opening size is smaller than the diameters of the second hollow rod 21 and the first hollow rod 20. The buckle 31 can be buckled on the outer peripheries of the second hollow rod 21 and the first hollow rod 20.

[0038] Refer to Figure 3 , Figure 4 , referring to the air cushion 10, the air delivery assembly includes an air delivery pipe 40 and a connector 41. The connector 41 is rotatably connected to one end of the air delivery pipe 40. The other end of the air delivery pipe 40 is fixed to one end of the first hollow rod 20. A communicating pipe 51 is fixed between the end of the first hollow rod 20 to which the air delivery pipe 40 is fixed and the end of the gas storage cylinder 50. The communicating pipe 51 communicates the gas storage cylinder 50 and the air delivery pipe 40.

[0039] Refer to Figure 4 , an inflation port 13 communicating with the inside of the air cushion 10 is fixed on the air cushion 10. A one-way valve 14 is fixed in the inflation port 13. The one-way valve 14 is composed of a valve body 1406, a core rod 1404 and a pressing plate 1401. The valve body 1406 is fixed in the inflation port 13. An air vent cavity 1405 is provided in the valve body 1406 and runs through along the axis direction of the inflation port 13. The air vent cavity 1405 communicates the inside of the air cushion 10 and the inflation port 13. The core rod 1404 runs through the valve body 1406 along the axis of the valve body 1406 and is slidably connected to it. A sealing plate 1403 is fixed to the end of the core rod 1404 away from the connector 41. The sealing plate 1403 can seal the air vent cavity 1405. The pressing plate 1401 is fixed to the other end of the core rod 1404. A return spring 1402 is fixed between the pressing plate 1401 and the valve body 1406. External threads are provided on the outer periphery of the inflation port 13, and internal threads are provided on the inner side surface of the connector 41. The connector 41 is threadedly connected to the outer periphery of the inflation port 13. The end of the air delivery pipe 40 provided with the connector 41 can be snapped into the inflation port 13.

[0040] Refer to Figure 4 , a valve core 42 that can abut against the one-way valve 14 is fixed inside the end of the air delivery pipe 40 close to the inflation port 13. The valve core 42 can abut against the pressing plate 1401. When the two abut against each other, both the valve core 42 and the one-way valve 14 are opened. When the valve core 42 is pressed in the direction away from the pressing plate 1401, the valve core 42 is in an open state.

[0041] When conducting water rescue, the air cushion 10 is in a retracted state. The rescue personnel can take a rescue boat and carry the present invention to quickly rush to the drowning person. When approaching the drowning person, pull the air cushion 10 in the direction away from the first hollow rod 20 to fully unfold it. At the same time, fasten the two connecting rods 30 to the first hollow rod 20 and the second hollow rod 21 through the buckles 31, place the first hollow rod 20 and the second hollow rod 21 on both sides of the drowning person, and the drowning person can hold the connecting rods 30 with both hands.

[0042] At this time, the rescue personnel pass the air cushion 10 under the drowning person and fasten the movable buckle 11 to the second hollow rod 21.

[0043] Then, connect the connector 41 to the inflation port 13. During this process, the valve core 42 abuts against the pressing plate 1401. As the connector 41 continues to rotate, the valve core 42 continuously moves in the direction close to the one-way valve 14, so that the valve core 42 is pressed. At the same time, the valve core 42 presses the pressing plate 1401 in the direction close to the air cushion 10, so that the ventilation cavity 1405 is communicated with the inside of the air cushion 10. At this time, the high-pressure carbon dioxide gas in the gas storage cylinder 50 is conveyed into the air cushion 10 through the air delivery pipe 40, so that the air cushion 10 quickly expands, and then the drowning person is buoyed on the water surface, which is convenient for the rescue personnel to carry him back by the rescue boat and also reduces the movement of the drowning person and the possibility of his secondary injury.

[0044] After the rescue is completed, the connector 41 can be removed from the inflation port 13, and the pressing plate 1401 is pressed, then the gas in the air cushion 10 can be released to make it return to a flat shape. At the same time, high-pressure carbon dioxide gas can be re-injected into the gas storage cylinder 50 through the air delivery pipe 40. After separating the connecting rod 30 from the first hollow rod 20 and the second hollow rod 21, the air cushion 10 can be re-wound onto the first hollow rod 20.

[0045] Those skilled in the art can clearly understand that various modifications can be made to the above embodiments without departing from the general spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scope of the present invention is subject to the appended claims of the present invention.
