Description
Technical Field
[0001] The invention relates to the field of underwater search and rescue and salvage, in particular to a window breaker used for underwater rescue. Background Art
[0002] In an emergency situation where a motor vehicle accidentally falls into water, if the passengers fail to escape quickly, the vehicle will sink rapidly, and rescuers are urgently needed to conduct underwater rescue. In an underwater environment, the main challenge faced by rescuers is how to quickly and effectively break the car windows 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 rescue.
[0003] In underwater environments, the effectiveness of traditional window-breaking tools, such as fire hammers or window breakers, is limited. These tools usually require two hands to operate, and the resistance of water will hinder the swinging action, making it difficult for rescuers to maintain a stable rescue posture, thus failing to effectively break the window. In addition, even when using energy storage window breakers, the resistance of water will interfere with its spring energy storage and energy release process, significantly reducing the window breaking effect. Energy storage window breakers rely on the elastic potential energy of the spring to break the glass, but 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 this emergency rescue scenario, rescuers are in urgent need of 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 that the car window can be broken 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. Experimental results show that even with a window-breaking hammer, it is difficult to break the car window glass underwater, because the resistance in the water not only blocks the swinging window-breaking hammer, but also makes it impossible to break the window because the rescuer cannot fix himself while floating in the water. In this case, rescuers often need additional auxiliary equipment to fix their position so that they can concentrate their strength on breaking the window.
[0005] Therefore, it is particularly important to design a window breaker that can effectively overcome the resistance of water, can be operated with one hand and can fix the rescuer in the process of rescuing a motor vehicle in an environment that is completely submerged in water. Summary of the invention
[0006] In view of the limitations of the prior art, the present invention provides a window breaker for underwater rescue, comprising an energy accumulator body, a main bracket, a main bracket handle, a suction cup, a bellows, a waterproof film, an alloy cone head, and a secondary bracket; the characteristics are: the main bracket is arranged on the side of the energy accumulator body, and a sealing cap is arranged on the top of the energy accumulator body, and the sealing cap seals the upper end of the energy accumulator body; a sealing ring is arranged at the lower end of the energy accumulator body; a bellows is arranged below the sealing ring, and a suction cup head is arranged below the bellows; the suction cup head and the suction cup are integrated, and the waterproof film seals the through hole of the energy storage ring to prevent water from entering; The main bracket and the energy storage device body are integrated, a long through hole is arranged in the main bracket, a main bracket slide groove is arranged on the side of the main bracket, a main bracket handle is arranged on the main bracket, the upper end of the spring coil is placed in the concave hole at the end of the main bracket handle, and the lower end is placed in the concave hole at the end of the auxiliary bracket handle; The inner cavity wall of the energy storage body is provided with an inclined convex strip, which is used to push the steel cone limit head to shift; An alloy steel cone, a strong spring and an energy storage ring return spring are installed in the inner cavity; An energy storage ring is arranged below the energy storage device body, and an energy storage ring platform is arranged in the middle of the energy storage ring; One end of the pull rod is fixed on the suction cup head, and the other end passes through the spring ring and the long through hole in the main bracket and is fixed below the auxiliary bracket; Under the action of the strong spring and the top ring, the limit head of the alloy steel cone always deviates toward the energy storage ring platform; When no external force is applied, the energy storage ring platform is always under the steel cone limit head under the joint action of the spring ring, the energy storage ring return spring and the spring ring; Use external force to fix the handle of the main bracket and lift the handle of the auxiliary bracket upward. The pull rod under the handle of the auxiliary bracket will drive the suction cup head and the energy storage ring to move upward. The energy storage ring platform on the energy storage ring will squeeze the strong spring to store energy until the steel cone limit head contacts the inclined convex strip on the inner wall of the inner cavity and then breaks away from the constraint of the energy storage ring platform. The alloy steel cone will instantly hit downward under the push of the strong spring, and the alloy cone head will protrude outside the waterproof film; After the main support handle and the auxiliary support handle lose the pressure of external force, the energy storage ring, the spring ring, the energy storage ring reset spring and the spring ring will automatically reset, and the energy storage ring platform will automatically return to under the steel cone limit head; Under the sealing effect of the sealing cap, bellows and waterproof film, when the window breaker is placed in water, water will not enter the cavity and the inside and outside of the energy storage circle.
[0007] The suction cup and bellows are made of soft rubber.
[0008] When no external force is applied, the distance between the bottom of the main bracket handle and the top of the auxiliary bracket handle is greater than the distance the energy storage ring needs to move upward to the point where the steel cone limit head contacts the inclined convex strip on the inner wall of the inner cavity and then breaks away from the constraint of the energy storage ring platform.
[0009] The cooperation between the limit pin and the inner slide groove can ensure that when the energy storage ring and the energy storage device body move, the axis lines of the two are always in an overlapping state.
[0010] The upper end of the bellows is fixed with the sealing ring, and the lower end is fixed with the suction cup head. The middle of the bellows does not contact with other components at any time.
[0011] The technical solution of the present invention has the following beneficial effects: 1. The underwater rescue window breaker of the present invention uses an energy storage device body, a strong spring and a suction cup in coordination, so that rescuers can use one hand to absorb the tempered glass window underwater and break it quickly.
[0012] 2. When using the present invention underwater, rescuers only need to hold the main bracket handle and the auxiliary bracket handle with one hand to exert force, which can release the energy of the strong spring and push the alloy cone head to instantly break through the waterproof film and hit the tempered glass, thereby reducing the difficulty of operation for rescuers.
[0013] 3. The suction cup design of the present invention enables the window breaker to be firmly adsorbed on the car window glass, providing a stable operating platform and reducing the instability during underwater operations.
[0014] 4. The sealing design of the sealing cap, bellows and waterproof film of the present invention ensures that water will not enter the interior of the window breaker when operating underwater, prevents water from generating resistance to the high-speed movement of the internal components of the energy storage device, and improves the efficiency of underwater window breaking.
[0015] 5. The soft suction cup design of the present invention allows the window breaker to be used on flat or curved tempered glass, increasing the versatility of underwater rescue.
[0016] The present invention can be operated with one hand, which not only improves the efficiency and success rate of underwater window breaking, but also enhances the stability and safety of the window breaking process, thus providing an effective tool for underwater rescue operations.

[0020] The suction cup 20 and the bellows 22 are made of soft rubber.
[0021] When no external force is applied, the distance between the bottom of the main bracket handle 14 and the top of the auxiliary bracket handle 43 is greater than the distance required for the energy storage ring 23 to move upward to the point where the steel cone limit head 31 contacts the inclined convex strip on the inner wall of the inner cavity 1001 and then break away from the constraint of the energy storage ring platform 2401.
[0022] The cooperation between the limiting pin 26 and the inner slide groove 2301 can ensure that when the energy storage ring 23 and the energy storage device body 10 move, the axis lines of the two are always in an overlapping state.
[0023] The upper end of the bellows 22 is fixed to the sealing ring 1002 , and the lower end is fixed to the suction cup head 21 . The middle of the bellows 22 does not contact with other components at any time.
[0024] In this embodiment, the length of the tapered rod is shorter than the length of the powerful spring not installed on the tapered rod. After assembly, the powerful spring is already in a state of being compressed by one quarter, so that the trigger stroke of the present invention is shortened and the explosive force of the powerful spring (75) is stronger.
[0025] The process of breaking the window of a motor vehicle during underwater rescue according to the present invention is as follows: Hold the main bracket handle 14 and the auxiliary bracket handle 43 with one hand, aim the suction cup cavity 2001 at the car window glass to be broken, and press the suction cup 20 against the glass until the moisture under the suction cup cavity 2001 is completely discharged, so that the suction cup cavity 2001 is firmly adsorbed on the car window glass; at this time, the hands holding the main bracket handle 14 and the auxiliary bracket handle 4 exert force to squeeze tightly, forcing the strong spring 33 to store energy and release energy, so as to instantly push the alloy cone head 32 to hit the tempered glass under the waterproof film 28 to break the window; to break another car window glass, relax the hands holding the main bracket handle 14 and the auxiliary bracket handle 43, and repeat the above actions. The method of use is the same for breaking a window on the water surface.
[0026] 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 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.
[0027] 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.
