Technical Field
[0001] The invention relates to the field of underwater search and rescue and salvage, in particular to an underwater rescue window breaking 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 rescue window-breaking device, comprising an energy storage device body, a suction cup, a cone head, a pull rod, and a strong magnetic steel; the characteristics are: a handle and a ferrule are arranged on the device body, and a sealing rubber sleeve is arranged in the ferrule; waterproof bearings are arranged on both sides of the device body; an inner cavity is arranged in the device body, a baffle is arranged on the side of the inner cavity, and a fixing frame and a main body through hole are arranged on the bottom surface of the inner cavity; A suction cup head is arranged on the suction cup, and the suction cup head is fixed below the device body; a suction cup cavity is arranged below the suction cup, a suction cup through hole is arranged in the middle of the suction cup cavity, and a waterproof film is arranged below the suction cup through hole; A cone tip is arranged below the cone head, a cone rod is arranged on the side of the cone head, the cone rod is fixed on the main shaft, the two ends of the main shaft are rotatably connected with the waterproof bearing, the shaft end of the large coil spring is fixed on the main shaft, and the fixed end of the large coil spring is fixed on the fixed frame; One end of the pull rod is provided with a fork head, and a slide groove is provided in the fork head; the other end of the pull rod is fixed on the rotating drum; the rotating drum is rotatably connected with the main shaft; a small coil spring is provided on the rotating drum, the shaft end of the small coil spring is fixed together with the rotating drum, and the fixed end of the small coil spring is fixed on the fixed frame; The strong magnetic steel is fixed in the magnetic steel sleeve, and convex strips are arranged on both sides of the magnetic steel sleeve. The convex strips are constrained by the two ends of the slide groove and cannot fall out, and the convex strips can slide back and forth in the slide groove; a handle is arranged on the strong magnetic steel, and a buckle is arranged on the handle, and the buckle is fixed to one end of the pull wire; the other end of the pull wire passes through the sealing rubber sleeve and is fixed to the wristband; The secondary shaft is fixed in the device body, the secondary shaft is rotatably connected to the pulley, and a pulley groove is provided on the outer circumference of the pulley; A pull bar is provided in the pull buckle, the pull bar is connected to one end of a tension spring, and the other end of the tension spring is sleeved on a positioning head provided on the pull rod; when there is no external force, the tension spring always pulls the pull buckle toward the direction close to the positioning head; When the strong magnetic steel is close to the cone head made of magnetic-affinity metal material, the cone head can be adsorbed together. The magnetic force of the strong magnetic steel adsorbing the cone head is greater than the maximum torque force applied by the large coil spring to the cone head when the cone head is attracted by the strong magnetic steel and driven to rotate upward to the maximum angle. When the cone head loses the sufficient magnetic attraction of the strong magnetic steel, under the standard atmospheric pressure, the cone head, under the action of the large coil spring, the force of the cone tip statically pressing the waterproof membrane is greater than 1 kg; When the strong magnetic steel is pulled by the pull line under the bracelet and turned up to 90 degrees, the buckle under the pull line will drive the strong magnetic steel to move upward to the outermost end of the fork head, so that the axis line of the strong magnetic steel and the axis line of the cone head are displaced by more than 20mm. At this time, the magnetic attraction of the strong magnetic steel on the cone head will be smaller than the torque force applied by the large coil spring to the cone head. The large coil spring will force the cone head to reset downward instantly, driving the cone tip to hit and pierce the waterproof film and protrude outside the waterproof film; Give up the control bracelet to relax the cable, and the fork head will return to the baffle under the action of the small coil spring; at the same time, the strong magnetic steel will automatically return to the original position under the action of the tension spring; When the fork head is on the baffle, the strong magnetic steel will suck the cone head upward, so that the cone tip returns to at least 1mm above the waterproof membrane.
[0007] The diameter of the through hole in the middle of the sealing 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.
[0008] Under the combined action of the waterproof bearing and the main 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.
[0009] The waterproof membrane is made of polyethylene PE material and has a thickness between 0.1 and 0.2 mm.
[0010] The strong magnetic steel is made of neodymium iron boron material, with a thickness of 10mm and a diameter of 20mm, and can achieve an adsorption force of more than 10 kg on the cone head.
[0011] The diameter of the cone head is greater than 25 mm.
[0012] 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 and quickly break the tempered glass window. This provides room for easy operation, allowing rescuers to perform rescue more quickly and effectively.
[0013] 2. Reduce the difficulty of operation: Just hold the handle with one hand to fix the window-breaking device on the window of the motor vehicle, and 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. This reduces the difficulty of operation for rescuers and improves the efficiency of rescue.
[0014] 3. Improved stability: The suction cup design allows the window-breaking device to be firmly attached to the car window glass, reducing the instability during underwater operations. This provides stability and ensures safety and reliability during the rescue process.
[0015] 4. Improve efficiency: The sealing design can ensure that water does not enter the window breaking device when it is working underwater, which can 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. This provides room for efficiency improvement, especially in underwater environments.
[0016] 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. This provides room for adaptability, allowing the device to be used in a variety of different rescue scenarios.
[0017] The invention has broad application prospects and practical value in the field of underwater rescue, and provides a more reliable rescue tool for rescuers. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0019] Below, the present invention will be further described in conjunction with the accompanying drawings and embodiments: Figure 1 — Figure 7 As shown, an underwater rescue window-breaking device comprises an energy storage device body 10, a suction cup 20, a cone head 30, a pull rod 40, and a strong magnetic steel 50; the characteristics are: a handle 11 and a ferrule 12 are arranged on the device body 10, and a sealing rubber sleeve 1201 is arranged in the ferrule 12; waterproof bearings 33 are fixedly arranged on both sides of the device body 10; an inner cavity 13 is arranged in the device body 10, a baffle 14 is arranged on the side of the inner cavity 13, and a fixing frame 16 and a main body through hole 15 are arranged on the bottom surface of the inner cavity 13; The suction cup 20 is provided with a suction cup head 2001, which is fixed below the device body 10; a suction cup cavity 21 is provided below the suction cup 20, a suction cup through hole 23 is provided in the middle of the suction cup cavity 21, and a waterproof membrane 22 with a thickness of ? is provided below the suction cup through hole 23; A cone tip 3001 is provided below the cone head 30, a cone rod 31 is provided on the side of the cone head 30, the cone rod 31 is fixed on the main shaft 34, the two ends of the main shaft 34 are rotatably connected with waterproof bearings 33, the shaft end of the large coil spring 32 is fixed on the main shaft 34, and the fixed end of the large coil spring 32 is fixed on the fixed frame 16; One end of the pull rod 40 is provided with a fork 43, and a slide groove 44 is provided in the fork 43; the other end of the pull rod 40 is fixed on the rotating drum 4001; the rotating drum 4001 is rotatably connected with the main shaft 34; a small coil spring 45 is provided on the rotating drum 4001, and the shaft end of the small coil spring 45 is fixed together with the rotating drum 4001, and the fixed end of the small coil spring 45 is fixed on the fixing frame 16; The strong magnetic steel 50 is fixed in the magnetic steel sleeve 51, and convex strips are arranged on both sides of the magnetic steel sleeve 51. The convex strips are constrained by the two ends of the slide groove 44 and cannot be disengaged. The convex strips can slide back and forth in the slide groove 44; a handle 52 is arranged on the strong magnetic steel 50, and a buckle 53 is arranged in the handle 52. The buckle 53 is fixed to one end of the pull wire 63; the other end of the pull wire 63 passes through the sealing rubber sleeve 1201 and is fixed to the wristband 64; The secondary shaft 60 is fixed in the device body 10, and the secondary shaft 60 is rotatably connected to the pulley 61, and a pulley groove 62 is provided on the outer circumferential surface of the pulley 61; The pull buckle 53 is provided with a pull bar 54, which is connected to one end of a tension spring 42, and the other end of the tension spring 42 is sleeved on a positioning head 41 provided on the pull rod 40; when there is no external force, the tension spring 42 always pulls the pull buckle 53 toward the direction close to the positioning head 41; When the strong magnetic steel 50 is close to the cone head 30 made of a magnetically affinity metal material, the cone head 30 can be adsorbed together. The magnetic force of the strong magnetic steel 50 adsorbing the cone head 30 is greater than the maximum torque force applied by the large coil spring 32 to the cone head 30 when the cone head 30 is attracted by the strong magnetic steel 50 and driven to rotate upward to the maximum angle. When the cone head 30 loses the sufficient magnetic attraction of the strong magnetic steel 50, under the standard atmospheric pressure, the cone head 30, under the action of the large coil spring 32, the cone tip 3001 statically presses the waterproof membrane 22 with a force greater than 1 kg; The area of the cone tip 3001 is less than 0.15 square millimeters. The force generated when the large coil spring 32 drives the cone tip 3001 under the cone head 30 to hit downward is at least 60 Newtons (N). The strength of the cone tip 3001 during impact is at least 375 MPa, to ensure that the tempered glass can be effectively shattered in an underwater environment.
[0020] When the strong magnetic steel 50 is pulled by the pull wire 63 under the bracelet 64 and turned up to 90 degrees, the buckle 53 under the pull wire 63 will drive the strong magnetic steel 50 to move upward to the outermost end of the fork head 43, so that the axis of the strong magnetic steel 50 and the axis of the cone head 30 are displaced by more than 20 mm. At this time, the magnetic attraction force of the strong magnetic steel 50 on the cone head 30 will be smaller than the torque force applied by the large coil spring 32 to the cone head 30. The large coil spring 32 will force the cone head 30 to reset downward instantly, driving the cone tip 3001 to hit and pierce the waterproof membrane 22 and protrude outside the waterproof membrane 22; Abandon the control bracelet 64 to relax the pull wire 63, and the fork head 43 will be reset to the baffle 14 under the action of the small coil spring 45; at the same time, the strong magnetic steel 50 will automatically reset under the action of the tension spring 42; When the fork head 43 is on the baffle 14 , the strong magnetic steel 50 will suck the cone head 30 upward, so that the cone tip 3001 retreats to at least 1 mm above the waterproof membrane 22 .
[0021] The diameter of the through hole in the middle of the sealing rubber sleeve 1201 is designed to be 0.05 mm smaller than the diameter of the pull wire 63 to ensure that no water will penetrate into the inner cavity 13 during underwater operation.
[0022] Under the combined action of the waterproof bearing 33 and the main shaft 34 , the suction cup cavity 21 and the waterproof membrane 22 , no water will penetrate into the inner cavity 13 before the waterproof membrane 22 is punctured by the cone tip 3001 .
[0023] The waterproof membrane 22 is made of polyethylene PE material, and its thickness is between 0.1 and 0.2 mm.
[0024] The strong magnetic steel 50 is made of neodymium iron boron material, has a thickness of 10 mm and a diameter of 20 mm, and can achieve an adsorption force of more than 10 kg on the cone head 30 .
[0025] The diameter of the cone head 30 is greater than 25 mm.
[0026] 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 20 at the car window glass to be broken and press it to discharge the moisture under the suction cup cavity 21, so that the suction cup cavity 21 is firmly adsorbed on the car window glass; continue to hold the handle 11, and pull the finger ring 64 toward the outside of the device body 10 with the other hand to store energy in the large coil spring 32 in the device body 10. When the finger ring 64 is pulled to make the axis line of the strong magnetic steel 50 and the axis line of the cone head 30 misaligned until the magnetic force of the strong magnetic steel 50 is less than the torque force applied by the large coil spring 32 to the cone head 30, the large coil spring 32 will drive the cone head 30 to instantly reset downward to hit the car window glass under the suction cup cavity 21, thereby breaking the window; repeat the above actions to continue breaking the window.
[0027] In this embodiment, the waterproof film 28 is made of elastic polyethylene (PE) material. When the alloy cone 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 alloy cone retreats, the opening can automatically shrink to a certain extent, thereby hindering the entry of water. 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.
[0028] 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.
