Description
Technical Field
[0001] The invention relates to the field of underwater search and rescue and salvage, in particular to an underwater broken window rescue device. Background Art
[0002] In the unfortunate event of a motor vehicle falling into water, if the passengers fail to escape in time, the vehicle will sink quickly and rescue operations are urgent. The primary challenge faced by underwater rescuers is how to quickly and effectively break the car windows in order to rescue the trapped people. The resistance of water and the buoyancy it creates on rescuers make underwater window-breaking rescue much more difficult and complex than land-based rescue.
[0003] In underwater environments, the effectiveness of traditional window-breaking tools, such as fire hammers or window breakers, is greatly reduced. The resistance of water will hinder the swinging action of these tools, making it difficult for rescuers to maintain a stable rescue posture, thus failing to effectively break the window. In addition, even if an energy storage window breaker is used, the resistance of water will slow down the movement of the spring, reduce the energy conversion efficiency, and thus weaken the penetration of the window breaker.
[0004] In such emergency rescue scenarios, rescuers urgently need a window-breaking tool that can be fixed on the glass and overcome water resistance. This tool must not only have enough power to penetrate the tempered glass, but also help the rescuer stay stable in the water so as to break the car window more accurately. More importantly, this tool should be able to be operated with one hand so that the rescuer can use the other hand to fix himself or perform other necessary operations.
[0005] Therefore, designing a window breaker that can effectively overcome the resistance of water, can be operated with one hand, and can fix the rescuer is particularly important in the process of rescuing a motor vehicle in an environment that is completely submerged in water. The development of this innovative tool is of great significance to improving the efficiency and success rate of underwater rescue. Summary of the invention
[0006] In view of the limitations of the prior art, the present invention provides an underwater window salvage device, comprising an energy storage device body, a cone head, a turntable, and a suction cup. The device body is characterized in that a handle and a ring are arranged on the top, and a suction cup is arranged on the bottom; a fixing ring is arranged on the side, and the device body is provided with an inner cavity, and a small fixing frame, a large fixing frame, a limit spring sheet, a spring sheet and a through hole are arranged at the bottom of the inner cavity; A rubber sleeve is arranged in the ferrule, and one end of the pull wire passes through the rubber sleeve and is fixed to the bracelet; the other end of the pull wire is inserted into the groove on the turntable and fixed to the fixing nail: the turntable is provided with a fixing nail; The large fixed frame is provided with a limited elastic sheet and is rotatably connected to one end of the driving shaft; the driving shaft is provided with a turntable, a small coil spring and a driving gear; the other end of the driving shaft is rotatably connected to a waterproof bearing, and the waterproof bearing is fixed to the side of the device body; when the pull wire loses external force and is pulled outward, the small coil spring always drives the turntable to retract the pull wire toward the inside of the device body until the bracelet is blocked by the rubber sleeve; The limit spring piece and the ratchet structure inside the driving gear together limit the driving gear to rotate in only one direction. The limit spring piece ensures that the driving gear will not rotate in the opposite direction, while the ratchet structure limits the rotation direction of the driving shaft in the driving gear. Therefore, under the action of these two structures, the turntable can only drive the driving gear to rotate in one direction; The small fixing frame is provided with a fixing block, and the small fixing frame is fixed together with one end of the passive shaft; the passive shaft is rotatably connected with the rotating sleeve, the rotating sleeve is provided with a passive gear and a cone rod, and the passive gear is provided with a fixing shaft; The shaft end of the large coil spring is fixed on the passive shaft, and the fixed end of the large coil spring is fixed on the fixed shaft; the shaft end of the small coil spring is fixed on the active shaft, and the fixed end of the small coil spring is fixed on the fixed block; A cone tip is arranged below the cone head, and the side surface is fixed to one end of the cone rod, and the other end of the cone rod is fixed to the rotating sleeve on the passive shaft; a fixing ring is arranged at one end of the passive shaft, and the fixing ring is fixed to the side surface of the device body; the other end of the passive shaft is fixed to the small fixing frame; The driving gear is provided with a notch, which cannot prevent the driving gear from rotating; the passive gear is only about a quarter of the complete gear. Driven by the driving gear, the passive gear will meet the notch set in the driving gear after rotating 110 degrees. After the passive gear loses the constraint of the driving gear, it will reset instantly under the action of the large coil spring, pushing the cone tip under the cone head through the through hole to hit the tempered glass under the suction cup; After the cone tip passes through the through hole and hits the tempered glass under the suction cup, the spring sheet lifts the cone rod, so that the waterproof film set under the suction cup cavity shrinks to reduce the hole pierced by the cone tip, preventing moisture from entering the inner cavity; The diameter of the through hole in the middle of the rubber sleeve is designed to be 0.05 mm smaller than the diameter of the pull wire to ensure that no water will penetrate into the inner cavity during underwater operation.
[0007] Under the combined action of the waterproof bearing and the driving shaft, the suction cup cavity and the waterproof membrane, no water will penetrate into the inner cavity before the waterproof membrane is punctured by the cone tip.
[0008] The waterproof film is made of polyethylene PE material, and its thickness is between 0.1 and 0.2 mm. The waterproof film prevents water from entering the suction cup cavity but does not affect the window breaking effect.
[0009] The area of the cone tip is less than 0.15 square millimeters. When the large coil spring drives the cone tip under the cone head to hit downward, the force generated is at least 60 Newtons (N). The strength of the cone tip of the window breaker during impact is at least 375 MPa to ensure that the tempered glass window can be effectively broken in an underwater environment.
[0010] The technical solution of the present invention has the following beneficial effects: 1. Convenience of one-handed operation: Rescuers can use one-handed operation underwater to absorb the tempered glass window and quickly break the tempered glass window. This allows rescuers to carry out rescue more quickly and effectively.
[0011] 2. Reduce the difficulty of operation: Just hold the handle with one hand to fix the window breaking device on the car window, then pull the finger ring to complete the energy storage and energy release, completing the whole process of the alloy cone head instantly breaking through the waterproof film and hitting the tempered glass.
[0012] 3. Improve stability: The suction cup enables the window breaking device to be firmly attached to the car window glass, reducing the instability during underwater operations, providing stability for rescuers, and ensuring safety and reliability during the rescue process.
[0013] 4. Improve efficiency: The sealing design can ensure that water will not enter the window breaking device when operating underwater, prevent water from causing resistance to the high-speed movement of the internal components of the energy storage device, and improve the efficiency of underwater window breaking.
[0014] 5. Enhanced versatility: The soft suction cup design allows the window breaking device to be used on flat or curved tempered glass, increasing the versatility of underwater rescue and allowing the device to be applied to a variety of different rescue scenarios.
[0015] The present invention has broad application prospects and practical value in the field of underwater rescue. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0017] Below, the present invention will be further described in conjunction with the accompanying drawings and embodiments: Figure 1 — Fig. 9 As shown, an underwater window salvage device includes an energy storage device body 10, a cone head 20, a turntable 30, and a suction cup 40: characterized in that: a handle 11 and a ring 50 are arranged on the top of the device body 10, and a suction cup 40 is arranged at the bottom; a fixing ring 24 is arranged on the side, and the device body 10 is provided with an inner cavity 1001, and a small fixing frame 12, a large fixing frame 13, a limiting spring piece 1301, a spring piece 14 and a through hole 1002 are arranged at the bottom of the inner cavity 1001; The ferrule 50 is provided with a rubber sleeve 51, one end of the pull wire 53 passes through the rubber sleeve 51 and is fixed to the wristband 52; the other end of the pull wire 53 is inserted into the groove 32 on the rotating disk 30 and is fixed to the fixing nail 31: the rotating disk 30 is provided with a fixing nail 31; The large fixed frame 13 is provided with a limit spring 1301 and is rotatably connected to one end of the driving shaft 36; the driving shaft 36 is provided with a turntable 30, a small coil spring 33 and a driving gear 35; the other end of the driving shaft 36 is rotatably connected to a waterproof bearing 37, and the waterproof bearing 37 is fixed to the side of the device body 10; when the pull wire 53 loses external force and is pulled outward, the small coil spring 33 always drives the turntable 30 to retract the pull wire 53 toward the inside of the device body 10 until the wristband 52 is blocked by the rubber sleeve 51; The limit spring piece 1301 and the ratchet structure inside the driving gear 35 together limit the driving gear to rotate in only one direction. The limit spring piece 1301 ensures that the driving gear 35 will not rotate in the opposite direction, while the ratchet structure limits the rotation direction of the driving shaft 36 in the driving gear 35. Therefore, under the action of these two structures, the rotating disk 30 can only drive the driving gear 35 to rotate in one direction; The small fixing frame 12 is provided with a fixing block 34, and the small fixing frame 12 is fixed together with one end of the passive shaft 23; the passive shaft 23 is rotatably connected with the rotating sleeve 2201, and the rotating sleeve 2201 is provided with a passive gear 26 and a cone rod 22, and the passive gear 26 is provided with a fixing shaft 27; The shaft end of the large coil spring 25 is fixed on the passive shaft 23, and the fixed end of the large coil spring 25 is fixed on the fixed shaft 27; in the absence of external force, the cone rod 22, under the action of the large coil spring 25, always pushes the cone tip 21 under the cone head 20 to the waterproof membrane 42, and under the support of the spring sheet 14, the cone tip 21 only protrudes 1mm outside the waterproof membrane (42); The shaft end of the small coil spring 33 is fixed on the driving shaft 36, and the fixed end of the small coil spring 33 is fixed on the fixed block 34; The cone head 20 is provided with a cone tip 21 below, and the side surface is fixed to one end of the cone rod 22, and the other end of the cone rod 22 is fixed to the rotating sleeve 2201 on the passive shaft 23; one end of the passive shaft 23 is provided with a fixing ring 24, and the fixing ring 24 is fixed to the side of the device body 10; the other end of the passive shaft 23 is fixed to the small fixing frame 12; The driving gear 35 is provided with a notch, which cannot prevent the driving gear 35 from rotating; the passive gear 26 is only about a quarter of the complete gear. Driven by the driving gear 35, the passive gear 26 will meet the notch provided in the driving gear 35 after rotating 110 degrees. After losing the constraint of the driving gear 35, the passive gear 26 will be instantly reset under the action of the large coil spring 25, pushing the cone tip 21 under the cone head 20 through the through hole 1002 to hit the tempered glass under the suction cup 40; After the cone tip 21 passes through the through hole 1002 and hits the tempered glass under the suction cup 40, the spring sheet 14 lifts the cone rod 22, so that the waterproof membrane 42 provided under the suction cup cavity 41 shrinks the hole penetrated by the cone tip 21, thereby preventing moisture from entering the inner cavity 1001; The diameter of the through hole in the middle of the rubber sleeve 51 is designed to be 0.05 mm smaller than the diameter of the pull wire 53 to ensure that no water will penetrate into the inner cavity 1001 during underwater operation.
[0018] Under the combined action of the waterproof bearing 37 and the driving shaft 36 , the suction cup cavity 41 and the waterproof membrane 42 , no water will penetrate into the inner cavity 1001 before the waterproof membrane 42 is punctured by the cone tip 21 .
[0019] The waterproof film 42 is made of polyethylene PE material, and its thickness is between 0.1 and 0.2 mm. The waterproof film 42 prevents water from entering the suction cup cavity 41 but does not affect the window breaking effect.
[0020] The area of the cone tip 21 is less than 0.15 square millimeters. The force generated when the large coil spring 25 drives the cone tip 21 under the cone head 20 to hit downward is at least 60 Newtons (N). The strength of the cone tip 21 of the window breaker during impact is at least 375 MPa, to ensure that the tempered glass windows of motor vehicles can be effectively shattered in an underwater environment.
[0021] The process of breaking the window of a motor vehicle during underwater rescue according to the present invention is as follows: Hold the handle 11 with one hand, aim the suction cup 40 at the car window glass to be broken and press it to discharge the moisture under the suction cup cavity 41, so that the suction cup cavity 41 is firmly adsorbed on the car window glass; continue to hold the handle 11, and use the other hand to pull the hand ring 52 toward the outside of the device body 1001, so that the large coil spring 25 in the device body 10 stores energy. When the hand ring 52 is pulled, the passive gear 26 rotates 110 degrees under the drive of the active gear 35 and meets the notch set in the active gear 35. After the passive gear 26 loses the constraint of the active gear 35, it is instantly reset under the action of the large coil spring 25, pushing the cone tip 21 under the cone head 20 through the through hole 1002 to hit the tempered glass under the suction cup 40 to break the window; repeat the above actions to continue breaking the window.
[0022] In this embodiment, the waterproof film 42 is made of elastic polyethylene (PE) material. When the cone tip 21 of the window breaker hits, the opening of the waterproof film will be stretched open, but due to the elastic retraction force of the polyethylene itself, after the cone tip retreats, the opening can automatically shrink to a certain extent, thereby hindering the entry of water to a certain extent. Moreover, its chemical properties are relatively stable, which can resist the influence of external environmental factors to a certain extent and play a good protective role on the internal structure.
[0023] The above embodiments of the present invention are typical implementations of the present invention, rather than limiting the implementations of the present invention. Obvious variations derived from the embodiments of the present invention are still within the scope of protection of the present invention.
