Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary life-saving, and specifically relates to an auxiliary life-saving device suitable for ice surface drowning victims. Background Technique

[0002] Ice surface drowning assistance refers to the process of using various auxiliary equipment and technologies to help drowning victims out of danger and safely return to the shore when encountering emergencies during activities on the ice surface. The main tools include lifebuoys, life jackets, life-saving boards, etc. The drowning assistance equipment and technologies on the ice surface can quickly provide buoyancy and stability in case of emergencies, reducing the risk of drowning; Currently, generally a lifebuoy is used to rescue ice surface drowning victims. However, the lifebuoy needs to be put on the body of the ice surface drowning victim. Rescue personnel usually throw the lifebuoy towards the ice surface drowning victim. However, the material of the lifebuoy is relatively light. When the ice surface drowning victim is far from the shore, it is difficult to send the lifebuoy to the side of the drowning victim. At this time, it may be necessary for the rescue personnel to travel on the ice surface to rescue the drowning victim. However, there may also be a situation where the ice surface breaks, increasing the difficulty of the rescue. Summary of the Invention

[0003] The purpose of the present invention is to provide an auxiliary life-saving device suitable for ice surface drowning victims to solve the problems raised in the above background technique.

[0004] To solve the above technical problems, the present invention is realized through the following technical solutions: The present invention is an auxiliary life-saving device suitable for ice surface drowning victims, including a circular arc floating frame one. The end of the circular arc floating frame one is provided with a circular arc floating frame two. The inner wall of the circular arc floating frame two is fixedly connected with a bolt frame. The surface of the bolt frame is fixedly connected with a pulling rope. The materials of the circular arc floating frame one and the circular arc floating frame two are both designed with cold resistance and light weight to ensure that the life-saving floating body can provide high buoyancy to ensure the final safe rescue. The bottoms of the circular arc floating frame one and the circular arc floating frame two are both provided with driving components; The driving component includes a bottom groove. The bottom groove is opened at the bottoms of the circular arc floating frame one and the circular arc floating frame two. The top of the inner wall of the bottom groove is fixedly connected with a vertical rod. The bottom of the vertical rod is fixedly connected with a fixing frame. The inner wall of the fixing frame is rotatably connected with a gear frame. The inner wall of the fixing frame is fixedly connected with a power device. The output end of the power device is fixedly connected with a driving wheel. The power device is set to be miniaturized. The gear frame and the driving wheel are designed with light weight to avoid affecting the buoyancy of the circular arc floating frame one and the circular arc floating frame two.

The ends of the circular arc floating frame one and the circular arc floating frame two close to each other are provided with an opening and closing component. The surfaces of the circular arc floating frame one and the circular arc floating frame two are provided with a rope sleeving component.

[0005] Further, the number of the rubber crawlers is set to four. The four rubber crawlers are set into two groups, and the number of each group is set to two. The gear rack is symmetrically arranged with the fixed frame as the center, and the surface of the gear rack meshes with the inner wall of the groove belt.

[0006] Further, the power device is located at one end of the fixed frame away from the gear rack. The two rubber crawlers are symmetrically arranged with the fixed frame as the center. The upper surface of the rubber crawler is located inside the bottom groove, and the lower surface of the rubber crawler extends to the outer end of the bottom of the bottom groove.

[0007] Further, the opening and closing component includes a clamping plate. The end of the clamping plate is fixedly connected to the end of the second arc floating frame. A clamping groove is formed on the surface of the first arc floating frame. A fixing rope is fixedly connected to the inner wall of the first arc floating frame. One end of the fixing rope away from the first arc floating frame is fixedly connected to a plug pin. An adaptation groove is formed at one end of the first arc floating frame away from the clamping groove. The fixed seat is made of a lightweight material, and the rotating plate and the clamping plate are also designed to be cold-resistant, lightweight, and miniaturized to improve buoyancy. One end of the second arc floating frame away from the clamping plate is fixedly connected to a rotating plate. A shaft rod is fixedly connected to the surface of the rotating plate. One end of the shaft rod away from the rotating plate is rotatably connected to the inner wall of the adaptation groove. Storage grooves are formed at the tops of the first arc floating frame and the second arc floating frame. Fixed seats are fixedly connected to the surfaces of the first arc floating frame and the second arc floating frame.

[0008] Further, the ends of the first arc floating frame and the second arc floating frame are in contact with each other. One end of the plug pin away from the fixing rope penetrates through the first arc floating frame and the clamping plate and extends into the first arc floating frame, and the surface of the clamping plate is in contact with the inner wall of the clamping groove.

[0009] Further, the number of the shaft rods is set to two. The two shaft rods are symmetrically arranged with the rotating plate as the center. The surface of the rotating plate is in contact with the inner wall of the adaptation groove. The two groups of rubber crawlers are symmetrically arranged with the fixed seat as the center.

[0010] Further, the rope sleeving component includes a rescue rope. One end of the rescue rope is fixedly connected to the surface of the fixed seat. A round hole rod is slidably connected to the surface of the rescue rope. One end of the rescue rope away from the fixed seat is fixedly connected to the surface of the round hole rod. A rubber protection pad is fixedly connected to the surface of the rescue rope.

[0011] Further, the number of the rescue ropes is set to two. The two rescue ropes are symmetrically arranged with the bolt frame as the center. One end of the rescue rope away from the fixed seat is arc-shaped, and the rubber protection pad is located inside the arc of the rescue rope.

[0012] The present invention has the following beneficial effects: When the present invention is used to rescue a person who has fallen into the water on the ice surface, the first arc-shaped floating frame and the second arc-shaped floating frame are placed on the ice surface. At this time, the bottom of the rubber track will contact the ice surface. Then, the power device is controlled to start working. When the power device rotates, it drives the rubber track to rotate through the meshing of the driving wheel and the groove belt. The friction between the rubber track and the ice surface pushes the first arc-shaped floating frame to move towards the person who has fallen into the water on the ice surface, avoiding the situation that the life buoy is too light in material and the rescuer cannot throw it accurately, which affects the rescue efficiency of the person who has fallen into the water on the ice surface. When it is necessary to adjust the moving direction of the first arc-shaped floating frame, the power device at the bottom of the first arc-shaped floating frame or the second arc-shaped floating frame is controlled to stop working. At this time, the working power device will drive the rubber track to rotate around the stopped rubber track, so as to adjust its moving direction, so as to achieve the purpose that the first arc-shaped floating frame can quickly move to the person who has fallen into the water on the ice surface. A gear rack is arranged inside the groove belt, and the gear rack can support the end of the groove belt far away from the driving wheel, improving the stability of the rubber track during operation. When the first arc-shaped floating frame falls into the water, the rubber track rotates and uses the resistance in the water to push the first arc-shaped floating frame to move in the water, avoiding the distance between the person who has fallen into the water on the ice surface and the ice surface from affecting the rescue effect of the first arc-shaped floating frame.

[0013] After the first arc-shaped floating frame and the second arc-shaped floating frame of the present invention move beside the person who has fallen into the water on the ice surface, the person who has fallen into the water on the ice surface can directly put the first arc-shaped floating frame and the second arc-shaped floating frame on the body surface and move them to the armpits. When it is inconvenient for the person who has fallen into the water on the ice surface to put the first arc-shaped floating frame on the body, the person who has fallen into the water on the ice surface can pull out the plug with one hand. At this time, the second arc-shaped floating frame will rotate around the rotating plate at the end of the first arc-shaped floating frame. At this time, the first arc-shaped floating frame and the second arc-shaped floating frame are in an unfolded state. Then, the person who has fallen into the water on the ice surface can push the first arc-shaped floating frame through the armpit and move it to the chest. After pushing the clamping plate at the end of the second arc-shaped floating frame into the inside of the card slot, insert the plug into the first arc-shaped floating frame to fix the clamping plate, so that the person who has fallen into the water on the ice surface can place the first arc-shaped floating frame and the second arc-shaped floating frame under the armpits for fixation, and use the buoyancy of the first arc-shaped floating frame to rescue the person who has fallen into the water on the ice surface.

[0014] When the person who has fallen into the water on the ice surface lacks physical strength, after the first arc-shaped floating frame moves beside the person who has fallen into the water on the ice surface, the person who has fallen into the water on the ice surface can directly pass the arm through the arc of the rescue rope. At this time, the rescuer on the shore pulls the second arc-shaped floating frame towards the shore by pulling the rope. After the second arc-shaped floating frame exerts a pulling force on the rescue rope, the round hole rod will slide on the surface of the rescue rope to tighten the rescue rope around the arm of the person who has fallen into the water on the ice surface, so as to achieve the purpose of fixing the person who has fallen into the water on the ice surface. At this time, the rescuer can pull the person who has fallen into the water on the ice surface to the shore through the pulling rope to complete the rescue. A rubber protection pad is arranged on the surface of the rescue rope to reduce the extrusion force of the rescue rope on the arm of the person who has fallen into the water on the ice surface.

[0015] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

An adaptation groove 26 is formed at one end of the first arc-shaped floating frame 1 away from the clamping groove 23. A rotating plate 27 is fixedly connected to one end of the second arc-shaped floating frame 2 away from the clamping plate 21. When the ice surface drowning person is not convenient to put the first arc-shaped floating frame 1 on the body, the ice surface drowning person can pull out the plug pin 22 with one hand. At this time, the second arc-shaped floating frame 2 will rotate at the end of the first arc-shaped floating frame 1 with the rotating plate 27 as the center. A shaft rod 28 is fixedly connected to the surface of the rotating plate 27. One end of the shaft rod 28 away from the rotating plate 27 is rotatably connected to the inner wall of the adaptation groove 26. Storage grooves 20 are formed at the tops of the first arc-shaped floating frame 1 and the second arc-shaped floating frame 2. Fixing seats 24 are fixedly connected to the surfaces of the first arc-shaped floating frame 1 and the second arc-shaped floating frame 2.

[0024] The ends of the first arc-shaped floating frame 1 and the second arc-shaped floating frame 2 are in contact with each other. One end of the plug pin 22 away from the fixing rope 25 penetrates through the first arc-shaped floating frame 1 and the clamping plate 21 and extends into the first arc-shaped floating frame 1. The surface of the clamping plate 21 is in contact with the inner wall of the clamping groove 23.

[0025] The number of the shaft rods 28 is set to two. At this time, the first arc-shaped floating frame 1 and the second arc-shaped floating frame 2 are in an unfolded state. The ice surface drowning person can then push the first arc-shaped floating frame 1 through the armpit and move it to the chest. After pushing the clamping plate 21 at the end of the second arc-shaped floating frame 2 into the inside of the clamping groove 23, insert the plug pin 22 into the first arc-shaped floating frame 1 to fix the clamping plate 21.

The two rescue ropes 30 are symmetrically arranged with the bolt frame 3 as the center. The end of the rescue rope 30 far from the fixed seat 24 is arc-shaped, and the rubber protection pad 32 is located inside the arc of the rescue rope 30.

[0028] When in use, when it is necessary to rescue a person who has fallen into the water on the ice surface, place the arc floating frame 1 and the arc floating frame 2 on the ice surface. At this time, the bottom of the rubber track 11 will contact the ice surface. Then, control the power device 16 to start working. When the power device 16 rotates, it drives the rubber track 11 to rotate through the meshing of the driving wheel 17 and the groove belt 13. The friction between the rubber track 11 and the ice surface pushes the arc floating frame 1 towards the person who has fallen into the water on the ice surface, avoiding the situation where the life buoy is too light and the rescuer cannot throw it accurately, which affects the rescue efficiency of the person who has fallen into the water on the ice surface. When it is necessary to adjust the moving direction of the arc floating frame 1, control the power device 16 at the bottom of the arc floating frame 1 or the arc floating frame 2 to stop working. At this time, the working power device 16 will drive the rubber track 11 to rotate around the stationary rubber track 11, so as to adjust its moving direction, so as to achieve the purpose that the arc floating frame 1 can quickly move to the person who has fallen into the water on the ice surface. A gear rack 14 is arranged inside the groove belt 13, and the gear rack 14 can support one end of the groove belt 13 far away from the driving wheel 17, improving the stability of the rubber track 11 during operation. When the arc floating frame 1 falls into the water, the rubber track 11 rotates and uses the resistance in the water to push the arc floating frame 1 to move in the water, avoiding the situation that the distance between the person who has fallen into the water on the ice surface and the ice surface affects the rescue effect of the arc floating frame 1. After the arc floating frame 1 and the arc floating frame 2 move to the side of the person who has fallen into the water on the ice surface, the person who has fallen into the water on the ice surface can directly put the arc floating frame 1 and the arc floating frame 2 on the body surface and move them to the armpits. When the person who has fallen into the water on the ice surface is inconvenient to put the arc floating frame 1 on the body, the person who has fallen into the water on the ice surface can pull out the bolt 22 with one hand. At this time, the arc floating frame 2 will rotate around the rotating plate 27 at the end of the arc floating frame 1. At this time, the arc floating frame 1 and the arc floating frame 2 are in an unfolded state. The person who has fallen into the water on the ice surface can then push the arc floating frame 1 through the armpit and move it to the chest. After pushing the clamping plate 21 at the end of the arc floating frame 2 into the inside of the card slot 23, insert the bolt 22 into the inside of the arc floating frame 1 to fix the clamping plate 21, so that the person who has fallen into the water on the ice surface can place the arc floating frame 1 and the arc floating frame 2 under the armpits for fixation, and use the buoyancy of the arc floating frame 1 to rescue the person who has fallen into the water on the ice surface. When the person who has fallen into the water on the ice surface lacks physical strength, after the arc floating frame 1 moves to the side of the person who has fallen into the water on the ice surface, the person who has fallen into the water on the ice surface can directly pass the arm through the arc of the rescue rope 30. At this time, the rescuer on the shore pulls the arc floating frame 2 towards the shore through the pull rope 4. After the arc floating frame 2 exerts a pulling force on the rescue rope 30, the round hole rod 31 will slide on the surface of the rescue rope 30 to tighten the rescue rope 30 around the arm of the person who has fallen into the water on the ice surface, so as to achieve the purpose of fixing the person who has fallen into the water on the ice surface. At this time, the rescuer can pull the person who has fallen into the water on the ice surface to the shore through the pull rope 4 to complete the rescue. A rubber protection pad 32 is arranged on the surface of the rescue rope 30, and the rubber protection pad 32 reduces the extrusion force of the rescue rope 30 on the arm of the person who has fallen into the water on the ice surface.
