[0002] At present, the rescue method used for victims of shipwrecks is mainly to search on the sea surface through search and rescue ships or helicopters, and the search process mainly relies on the naked eye observation of the search and rescue personnel. Undoubtedly, this method can only search on the sea surface, and cannot search in the water under the sea surface. In addition, helicopters and other aircraft are high above the sea surface, which puts more pressure on the eyesight of the search and rescue personnel. As their energy is depleted, it is difficult for the search and rescue personnel to continue searching for a long time.

[0003] A salvage frame has been developed and designed in the field. It can be led by an aircraft to search the sea surface, and is equipped with a camera to transmit the images back to the rescuers, which can effectively solve the problem of rescuers being exhausted for a long time. In order to rescue the victims as soon as possible, a lifebuoy will be placed at the bottom of the salvage frame, and the victims need to take down the lifebuoy and use it by themselves. However, due to the large buoyancy of the lifebuoy and the flexible connection between the salvage frame and the aircraft, it is difficult for the salvage frame to sink below the water surface, and thus it is difficult to explore and rescue the situation under the water surface. In addition, the lifebuoy is hung at a high position, and the victims have difficulty in having the physical strength to take down the lifebuoy. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1 A surface rescue salvage frame shown in the figure includes a main case 1, a traction cable 2 is fixedly connected to the top of the main case 1, the upper end of the traction cable 2 is connected to the aircraft, a straight tube 3 is sleeved on the outside of the traction cable 2, the traction cable 2 can move up and down relative to the straight tube 3, and the length of the straight tube 3 is less than the length of the traction cable 2; a winch is installed in the aircraft, and the traction cable 2 is installed on the winch, and the traction cable 2 can be shortened by the winch. When the traction cable 2 is shortened to be equal to the straight tube 3, the main case 1 is connected to the aircraft through the straight tube 3, and the aircraft can descend in flight altitude, and the main case 1 can be lowered in altitude to enter the water, so that searching can be carried out under the water surface.

[0021] A baffle 4 is installed on the top of the main box 1, and the orthographic projection area of ​​the baffle 4 is larger than the diameter of the straight pipe 3. The traction cable 2 is fixedly connected to the center of the baffle 4. When the traction cable 2 is wound, the baffle 4 can replace the main box 1 to support the straight pipe 3, which can protect the main box 1 from wear.

[0022] A triangular suspension 5 is provided below the main chassis 1, and two oblique arms of the triangular suspension 5 are connected to the side surfaces of the main chassis 1. The bottom wall of the triangular suspension 5 is suspended below the main chassis 1 and can be used as a handle for the victims to grab.

[0023] An opening 6 is provided on the front side of the main case 1, and a foldable swimming ring 7 is placed inside the main case 1. The foldable swimming ring 7 is connected to a small underwater breathing apparatus through a rope, and the foldable swimming ring 7 can be popped out from the opening 6 and automatically inflated. The rope connects the foldable swimming ring 7 and the small underwater breathing apparatus together. When the foldable swimming ring 7 is popped out, the small underwater breathing apparatus can be brought out together with the foldable swimming ring 7. The victim can wear the small underwater breathing apparatus to relieve the difficulty of being unable to breathe, and float back to the water surface through the inflated swimming ring, which is convenient for search and rescue personnel to rescue.

[0024] Specifically, Figure 2 The main case 1 is provided with a receiving chamber 8 corresponding to the opening 6, and the foldable swimming ring 7 and the small underwater breathing apparatus (not shown in the figure) are placed in the receiving chamber 8. In the initial state, the opening 6 is sealed by a film. When the foldable swimming ring 7 pops out, the impact force destroys the film and causes the foldable swimming ring 7 to pop out.

[0025] An inflatable chamber 9 is provided adjacent to the accommodating chamber 8 in the main case 1. In this embodiment, the inflatable chamber 9 is located above the accommodating chamber 8. A compressed gas tank 10 is installed in the inflatable chamber 9. The compressed gas tank 10 is connected to the folding swimming ring 7 through an air pipe 11. After the compressed gas tank 10 is opened, the folding swimming ring 7 can be inflated through the air pipe 11. By comparing the pressure of the compressed gas tank 10 and the water pressure at different depths outside, the diving limit depth can be set. Within the limit depth, the compressed gas tank 10 can be used normally. The amount of gas in the compressed gas tank 10 is sufficient to satisfy the amount of gas inflated in one swimming ring. A one-way valve can be installed at the opening 6 of the compressed gas tank 10 to prevent the reflux of gas. The length of the air pipe 11 satisfies the distance of the folding swimming ring 7 from the accommodating chamber 8 after inflating. After inflating, the air pipe 11 can be pulled out of the air nozzle of the folding swimming ring 7, and the air nozzle of the folding swimming ring 7 can be manually closed. In this way, the length of the trachea 11 is shortened as much as possible to prevent the trachea 11 from being too long, the inflation speed of the foldable swimming ring 7 from being low, and the rescue from being delayed.

[0026] A driving chamber 12 is provided adjacent to the accommodating chamber 8 in the main case 1. In this embodiment, the driving chamber 12 is at the same height as the accommodating chamber 8. An electromagnet 13 is installed in the driving chamber 12. An iron plate 14 is attracted to the electromagnet 13 by magnetic force. The other end of the iron plate 14 is connected to a push plate 16 located in the accommodating chamber 8 through a connecting rod 15. A spring 17 is sleeved on the push rod in the accommodating chamber 8. One end of the spring 17 acts on the push plate 16 and the other end acts on the inner wall of the accommodating chamber 8. At this time, the spring 17 is in a compressed state. The push plate 16 is facing the folding swimming ring 7. The electromagnet 13 is powered off to eliminate the magnetic force, thereby relieving the restriction on the spring 17. The spring 17 is released from compression and returns to its original length to generate elastic force to drive the push plate 16 to push out the folding swimming ring 7. The accommodating chamber 8 through which the push rod passes is adjacent to the driving chamber 12 and is well sealed for water resistance.

[0027] A winding chamber 18 is provided adjacent to the accommodating chamber 8 in the main case 1. In this embodiment, the winding chamber 18 is located at the bottom of the driving chamber 12. A spool 19 is rotatably connected in the winding chamber 18, and a safety rope 20 is wound around the spool 19. The other end of the safety rope 20 extends into the accommodating chamber 8 and is fixed to the foldable swimming ring 7. The safety rope 20 is used to connect the foldable swimming ring 7 to the main case 1. The victim can follow the swimming ring and the main case 1 to rise to the water surface, or the aircraft can drag the main case 1 on the water surface to further drag the victim's swimming ring on the water surface to move closer to the rescue ship.

[0028] In order to facilitate underwater search and rescue, a camera 21 is installed on the front side of the main box 1 to detect the underwater situation.

[0029] In addition, the remaining space in the main box 1 can be used to install an electronic control system and a signal transmission system, which can send the image signal of the camera 21 to the rescue personnel in the rescue ship or aircraft, and can link the compressed gas tank 10 with the electromagnet 13 to realize the automatic start and sequential operation of the pop-up and inflation of the foldable swimming ring 7. In addition, a start button with an indicator light can be set on the front side of the main box 1. The start button lights up to indicate the victim to manually start the compressed gas tank 10 and link to close the electromagnet 13 to pop out the swimming ring.

[0030] When not in use during the water entry process, the traction cable 2 can be extended to a length greater than the straight tube 3, so that the aircraft and the main box 1 are flexibly connected to reduce wear. When preparing to enter the water, the length of the traction cable 2 is shortened so that the main box 1 is against the lower end of the straight tube 3, so that the main box 1 can enter the water by lowering the height. This water entry method is not affected by buoyancy, and water entry can be achieved even if the foldable swimming ring 7 is released and inflated in advance.

[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
