Description

Technical Field

[0001] The utility model relates to the technical field of underwater rescue, in particular to an underwater rescue vehicle with multiple inflatable air bags. Background Art

[0002] Drowning incidents are not uncommon in various natural or artificial water bodies such as rivers, lakes, reservoirs, and swimming pools. When a drowning incident occurs, it is very important to rescue the person who falls into the water quickly and effectively.

[0003] Currently, most rescue methods for drowning victims rely on manual rescue, either by dropping floating objects onto the water for the victim to grab, or by having skilled water rescuers jump into the water to carry out the rescue. Manual rescue is particularly inefficient in mass drowning incidents. The method of dropping floating objects requires the victim to actively grab the object, but this is affected by wind, waves, the victim's own reaction speed, and physical condition, making it impossible to guarantee that the victim will be able to grab the object. The rescue method of diving is affected by the rescuer's own physical fitness, water temperature, light, and water quality. The diving depth and duration are uncertain, and there is no guarantee that the rescuer will be able to find the victim and bring them out of the water. In mass drowning incidents, there may be a disparity in the number of rescuers and drowning victims, making it impossible to guarantee that every drowning victim will be rescued by the rescuers.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figures 1 to 6As shown, an underwater rescue vehicle with multiple inflatable airbags includes a main cabin 10, wherein a plurality of vertical propellers 11 are evenly distributed inside the main cabin 10, and a pair of horizontal propellers 12 are symmetrically distributed on the left and right sides of the main cabin 10. A storage box 14 is centrally connected to the lower side of the main cabin 10, and a plurality of life-saving boxes 15 are stacked inside the storage box 14. An inflatable airbag 16 is provided inside each life-saving box 15, and the left and right sides of the inflatable airbag 16 are symmetrically connected. Two nylon ropes 17 are connected, each with a magnet 18 at its end. The magnets 18 are magnetically attracted to the front side of the life-saving box 15. A self-locking buckle 19 is fixed to the side of each magnet 18. An airbag switch 20 is provided on the rear side of the life-saving box 15, and a pull rope 21 is connected to the airbag switch 20. An automatic airbag fastening structure is provided below the main cabin 10. The automatic airbag fastening structure is used to automatically fasten the inflatable airbag 16 in the life-saving box 15 to the body of the rescued person. The automatic airbag fastening structure automatically fastens the inflatable airbag 16 in the life-saving box 15 to the body of the rescued person through the cooperation between the nylon rope 17 and the self-locking buckle 19. The pull rope 21 is used to open the airbag switch 20, allowing the compressed air in the cylinder to be quickly input into the inflatable airbag 16, causing the inflatable airbag 16 to rapidly inflate and bring the rescued person out of the water.

[0026] In this embodiment, an underwater camera 13 is centrally located on the front side of the main engine room 10. When searching for rescued persons underwater, the underwater camera 13 can provide a clear underwater view in real time to rescuers on shore.

[0027] In this embodiment, the automatic airbag fastening structure includes a mounting frame 22, which is a U-shaped structure centrally connected to the lower side of the storage box 14. A mounting block 23 is mounted within the mounting frame 22, and a mounting bar 24 is slidably connected between the mounting block 23 and the mounting frame 22. A rack 25 is connected parallel to the mounting bar 24. A steering gear 26 is mounted on the rear side of the mounting frame 22. The output end of the steering gear 26 is keyed to a gear 27, which meshes with the rack 25. The steering gear 26 drives the mounting bar 24 forward through the gear 27 and rack 25, pushing the lifesaving box 15 in the storage box 14 toward the person being rescued.

[0028] In this embodiment, a second mounting frame 28 is mounted on the front end of the first mounting bar 24. A pair of second mounting bars 29 are connected in parallel within the second mounting frame 28. A second rack 30 is connected in parallel to the second mounting bars 29. A second servo 31 is mounted within the second mounting frame 28. The output end of the second servo 31 is keyed to a second gear 32, which meshes with the upper and lower racks 30. The second servo 31, through transmission between the second gear 32 and the upper and lower racks 30, drives the upper and lower mounting bars 29 toward each other, automatically fastening the inflatable airbag 16 in the life-saving box 15 to the body of the rescued person via a nylon rope 17 and a self-locking buckle 19.

[0029] In this embodiment, a positioning bar 33 is vertically connected to the upper side of the second mounting bar 29. A pair of positioning pins 34 are vertically mounted on the upper portion of the positioning bar 33. A pair of corresponding positioning holes are provided in the magnet block 18. The insertion and engagement between the positioning pins 34 and the positioning holes allows the lifesaving box 15 in the storage box 14 to be more accurately pushed toward the person being rescued, and the inflatable airbag 16 in the lifesaving box 15 to be more accurately fastened to the person's limbs.

[0030] In this embodiment, a pulling post 35 is vertically connected to the upper side of the first mounting bar 24 and is located behind the second mounting frame 28. Once the inflatable airbag 16 is fastened to the victim's limb, the airbag switch 20 is automatically opened by the pulling action between the retracted first mounting bar 24 and the pulling post 35 and the pulling rope 21, allowing the compressed air in the cylinder to be quickly input into the inflatable airbag 16.

[0031] The working principle of this underwater rescue vehicle with multiple inflatable air bags:

[0032] After the underwater rescue vehicle dives underwater and locates the person to be rescued, it approaches the person and first uses steering gear 1 26 to push out the life box 15. With the assistance of underwater camera 13, it uses thrusters 11 and 2 12 to adjust its posture, positioning the rescue elephant partially between two self-locking buckles 19. Then, it uses steering gear 2 32 to lock the two self-locking buckles 19. When the underwater rescue vehicle moves away from the rescuer, it simultaneously pulls the airbag switch 20, rapidly inflating the inflatable airbag 16 and bringing the person to the surface. The underwater rescue vehicle continues searching for other rescue targets, repeating the above steps.

[0033] Therefore, the embodiments disclosed above are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
