[0035] Example:

[0036] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A floating stretcher for water rescue, including a floating frame 1, and further comprising:

[0037] Stretcher board 2, which is movably connected inside the floating frame 1, is used to place the wounded.

[0038] The covering assembly 3 is provided in two sets and is symmetrically arranged on both sides of the stretcher board 2. The two sets of covering assemblies 3 are interlocked with each other.

[0039] The strap assembly 4 has two sets, symmetrically arranged on both sides of the stretcher board 2, and is connected to the covering assembly 3; and

[0040] Lifting component 5 is installed on the floating frame 1 and is used for lifting and displacing the stretcher plate 2.

[0041] Specifically, the stretcher board 2 floats on the water surface via the floating frame 1. After the rescuers place the injured person on the stretcher board 2, they control the action of the covering component 3 to block sunlight and rain. At the same time, the strap component 4 automatically works to bind and secure the injured person, improving the rescue efficiency and effectiveness. When the strap component 4 secures the injured person to the stretcher board 2, the lifting component 5 is activated to lift the stretcher board 2, raising the injured person to a height above the water surface, preventing wound infection and improving the safety and effectiveness of stretcher use.

[0042] Reference Figure 1 , Figure 2 and Figure 6 As a preferred embodiment of the present invention, the covering assembly 3 includes a movable rod 301 slidably connected to the outside of the stretcher plate 2, an end rod 302 fixedly mounted on the movable rod 301, a rain curtain 303 connected to the end rod 302, the rain curtain 303 movably connected inside the stretcher plate 2, the stretcher plate 2 having a receiving groove 6, the movable rod 601 slidably connected inside the receiving groove 6, the end of the rain curtain 303 away from the movable rod 301 connected to the movable rod 601, and a first elastic force provided between the movable rod 601 and the inner wall of the receiving groove 6. Component 602; Specifically, after the rescuer places the injured person on the stretcher board 2, he pulls the end rods 302 on both sides of the stretcher board 2, so that the two end rods 302 move closer to each other. During the movement of the end rods 302, the rain curtain 303 is pulled out from the stretcher board 2, the first elastic element 602 is stretched, and then the two end rods 302 interlock when they come into contact, so that the rain curtain 303 can shield the injured person from rain or sunlight, without the rescuer having to hold an umbrella and push the stretcher at the same time, thus improving the rescue effect and safety of the rescuer.

[0043] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7As a preferred technical solution of the present invention, the end rods 302 of the two sets of covering components 3 are interlocked. One end rod 302 is fixedly provided with an insert block 7, and the insert block 7 has a groove 701. A positioning block 702 is slidably connected in the groove 701. A second elastic element 703 is provided between the positioning block 702 and the inner wall of the groove 701. The top of the positioning block 702 is provided with a pressing slope. The other end rod 302 has a slot 8 that cooperates with the insert block 7 and a positioning groove 801 that communicates with the slot 8. The positioning block 702 is movably connected in the positioning groove 801. Specifically, when the two end rods 302 approach and contact each other, one end rod 302 will... The insert 7 of rod 302 is inserted into the groove 701 of the other end rod 302. During this process, the positioning block 702 avoids the other end rod 302 until the positioning block 702 matches and aligns with the positioning groove 801 in the slot 8. The positioning block 702 is reset and moved under the elastic force of the second elastic element 703. The positioning block 702 enters the positioning groove 801, restricting the two end rods 302 and enabling the rain curtain 303 to open. When it is necessary to disconnect the two end rods 302, the positioning block 702 only needs to be retracted into the groove 701. The end rods 302 and the rain curtain 303 are reset and moved under the pulling force of the first elastic element 602.

[0044] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As a preferred technical solution of the present invention, the strap assembly 4 includes two track plates 401 fixed on the stretcher plate 2. Each track plate 401 has a track groove 4011. A movable block 402 is movably connected in the track groove 4011. Both movable blocks 402 are connected to a mounting seat 403 through a connecting rod. A strap body 404 is provided between the two mounting seats 403.

[0045] Furthermore, one of the mounting bases 403 is fixedly connected to one end of the strap body 404, and the other mounting base 403 is provided with a mounting groove 12. A rotating rod 121 is rotatably connected in the mounting groove 12. A second torsion spring 122 is provided between the rotating rod 121 and the mounting base 403. The other end of the strap body 404 is wrapped around and connected to the rotating rod 121. A limiting tooth 13 that moves against the strap body 404 is also fixed on the stretcher plate 2.

[0046] Furthermore, a rotating shaft 9 is rotatably connected to the stretcher plate 2, and a driven gear 902 is provided on the rotating shaft 9. A rack plate 3011 that meshes with the driven gear 902 is provided on the moving rod 301. A pull rope 901 is wound around the rotating shaft 9. The end of the pull rope 901 away from the rotating shaft 9 is connected to the movable block 402. A support 10 is fixedly provided on the stretcher plate 2. An elastic telescopic rod 11 is connected to the support 10 through a pin. A first torsion spring 111 for resetting the rotation of the elastic telescopic rod 11 is sleeved on the pin. The end of the elastic telescopic rod 11 away from the support 10 is movably connected to the movable block 402.

[0047] Specifically, when the covering component 3 is activated, the moving rod 301 drives the rack plate 3011 to move and mesh with the driven gear 902 for transmission. The driven gear 902 drives the rotating shaft 9 to rotate, thereby winding the pull rope 901. During the winding process, the pull rope 901 pulls the movable block 402. The movable block 402 first moves horizontally along the track groove 4011 and then moves from top to bottom. The movable block 402 drives the mounting base 403 to move through the connecting rod, thereby causing the strap body 404 between the two mounting bases 403 to gradually move closer to the injured person's body. During this process, the movable block 402 drives the elastic telescopic rod 11 to deflect and be stretched. When the strap body 404 comes into contact with the injured person's body, As the mounting base 403 continues to move downward, the strap body 404 wound on one of the mounting base 403 rotating rods 121 is automatically released, so that the length of the strap body 404 automatically adapts to the curved surface of the injured person's body. When the mounting base 403 moves to the lowest point, the mounting base 403 drives the strap body 404 to press against the limiting tooth 13. The limiting tooth 13 can restrict the strap body 404 from being released further or be wound up under the action of the second torsion spring 122, so that the strap body 404 keeps the injured person in a limiting state, automatically binding and fixing the injured person without the need for rescuers to manually adjust the tightness of the strap and then lock it, thus improving the rescue efficiency and rescue effect of rescuers.

[0048] Reference Figure 1 , Figure 2 , Figure 4 and Figure 8 As a preferred technical solution of the present invention, the lifting assembly 5 includes a U-shaped plate 14 fixed on the stretcher plate 2 by a connecting rod. The U-shaped plate 14 is rotatably connected to the rotating shaft 9. The rotating shaft 9 is provided with a driving bevel gear 903. The U-shaped plate 14 is rotatably provided with a driven bevel gear 141 that meshes with the driving bevel gear 903. A screw 15 is slidably provided on the driven bevel gear 141. The screw 15 is fixedly connected to the floating frame 1. The stretcher plate 2 is provided with a nut seat 16 that is threadedly connected to the screw 15.

[0049] Furthermore, the driven bevel gear 141 is provided with a guide bar 1411, and the screw 15 is provided with a guide groove 151 that cooperates with the guide bar 1411.

[0050] Specifically, initially, the height between the stretcher plate 2 and the floating frame 1 is small, making it easy for rescuers to quickly place the injured person on the stretcher plate 2. When the strap assembly 4 is working, the rotation of the rotating shaft 9 will drive the active bevel gear 903 to mesh with the driven bevel gear 141 on the U-shaped plate 14, causing the driven bevel gear 141 to drive the screw 15 to rotate through the guide bar 1411. Since the nut seat 16 and the screw 15 are threaded together, when the screw 15 rotates, the nut seat 16 drives the stretcher plate 2 to move upward. The upward movement of the stretcher plate 2 will drive the U-shaped plate 14 to move upward. The U-shaped plate 14 will drive the driven bevel gear 141 to move upward synchronously, so that the driven bevel gear 141 slides on the outside of the screw 15 when it drives the screw 15 to rotate. The lifting of the stretcher plate 2 raises the injured person to a height that is detached from the water surface, avoiding infection of the injured person's wounds and improving the safety of stretcher use and rescue effectiveness.

[0051] Reference Figure 1 and Figure 2 As a preferred technical solution of the present invention, several handles 101 are symmetrically arranged on both sides of the floating frame 1, and lifting rods 201 are provided at both ends of the stretcher plate 2; the handles 101 on the floating frame 1 facilitate rescuers to drag the stretcher in the water, and the lifting rods 201 on the stretcher plate 2 facilitate rescuers to lift the stretcher by lifting rods 201 when they arrive on shore.

[0052] Reference Figure 1 As a preferred technical solution of the present invention, a fluorescent strip 102 is provided on the outer side of the floating frame 1; the fluorescent strip 102 on the floating frame 1 can remind other personnel of the position of the stretcher and improve the visibility during field rescue.
