Description

Technical Field

[0001] The invention discloses a fire-fighting drone used for breaking windows on floors, belonging to the field of fire-fighting equipment. Background Art

[0002] Drones can quickly fly to designated locations in high-rise buildings to perform window-breaking tasks, greatly shortening rescue time. Drones can be precisely controlled through remote control or preset programs to ensure the accuracy of the window-breaking location. In addition to the window-breaking function, some firefighting drones also have multiple functions such as fire extinguishing, image transmission, and ranging to meet the needs of different scenarios. Drone window-breaking operations can reduce the risk of firefighters directly facing the fire scene and improve the safety of rescue operations.

[0003] There are some problems with existing window-breaking drones: Although the window-breaking devices currently carried by drones have achieved the needs of non-contact rapid window breaking to a certain extent, and play an important role in emergency rescue and fire fighting scenes, their technical implementation methods are often accompanied by several significant limitations and safety hazards.

[0004] First, the problem of glass splashing is one of the most obvious and urgent problems to be solved in traditional window breaking methods. When a high-speed impactor (such as a projectile, a hammer, etc.) directly hits the glass surface, the energy released instantly will cause glass fragments to fly everywhere, which may not only injure people around, but also cause secondary damage to precision equipment or flammable items in the surrounding environment.

[0005] Secondly, the problem of energy concentration caused by single-point impact cannot be ignored. Although single-point impact can break glass in a short time, its huge impact force often causes the impactor to maintain a high kinetic energy after penetrating the glass. If it is not effectively controlled, it may continue to penetrate into the indoor space and pose a threat to people or objects inside. Summary of the invention

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0030] When a high-speed impact object (such as a projectile, a hammer, etc.) directly acts on the glass surface, the energy released instantly will cause glass fragments to fly everywhere, which may not only injure people around, but also cause secondary damage to precision equipment or flammable items in the surrounding environment. Therefore, in order to solve the above problems, this case proposes the following technical solutions: See also Figures 1 to 8 The present invention provides a technical solution for a firefighting drone for breaking windows on floors: its structure includes: a fuselage 2, an image collector 4 is provided at the front end of the fuselage 2, wings 3 are provided on both sides of the fuselage 2, a window breaking part 1 is also installed at the front end of the fuselage 2, the window breaking part 1 is located at the bottom of the image collector 4, a protective shell 12 of the window breaking part 1 is fixed to the bottom of the fuselage 2, and a bracket 13 is provided on the plate body of the protective shell 12 extending downward, a transmitter 11 is nested inside the protective shell 12, and the transmitter 11 is connected to the internal circuit of the fuselage 2 through the internal contacts of the protective shell 12; The transmitter 11 includes a puncture portion 111 and a fixing seat 112. A reset spring 114 is installed inside the fixing seat 112. A limiter 113 is nested inside the reset spring 114. The limiter 113 is located on the inner wall of the fixing seat 112. The puncture portion 111 is embedded in the inner groove of the fixing seat 112 to compress the reset spring 114 and the limiter 113. The puncture portion 111 includes an adhesive ring 101 and a suction cup 102 . The adhesive ring 101 is located on the suction surface of the suction cup 102 . A spring pin 106 and a trigger groove 107 are embedded in the middle of the suction cup 102 to form a window breaker.

[0031] The main structure of the device includes a fuselage 2, with wings 3 on the side of the fuselage 2, an image collector 4 at the front end of the fuselage 2, the image collector 4 is used for image recognition and feedback of the real-time situation of the target area to facilitate the window breaking work, and a window breaking part 1 is provided at the bottom of the image collector 4, which is used for fixed-point window breaking work.

[0032] The window breaking part 1 is installed at the bottom of the fuselage 2 through a protective shell 12, and a bracket 13 is provided for support. A transmitter 11 is nested inside the protective shell 12. The transmitter 11 and the protective shell 12 can be disassembled, and contacts are provided inside for contact, which is convenient for disassembly and replacement.

[0033] The specific transmitter 11 includes a fixing seat 112, and a limiter 113 is installed inside the fixing seat 112. The limiter 113 is nested with a return spring 114. The return spring 114 drives the top balance block 115 to push the puncture part 111, wherein the side of the balance block 115 is provided with a detector 116, and the detector 116 is installed on the balance block 115 and the fixing seat 112. When the puncture part 111 is installed, the balance block 115 is opposite to the detector 116 on the fixing seat 112, and an electrical signal is formed to be fed back to the inside of the fuselage 2. The specific detector 116 adopts the cooperation of a Hall sensor and a magnetic block to detect the current working state by magnetic induction. When it is detected that the current balance block 115 is in the emission state, the bottom adjustment motor 302 is in the post-emission state, that is, the limit clip 52 is loose, which is convenient for subsequent assembly. When the assembly squeezes the balance block 115 to be opposite to the detector 116 on the fixing seat 112, the adjustment motor 302 is reset and locked again.

[0034] The puncture part 111 includes an adhesive ring 101, which is installed on the inner wall of the suction cup 102 for adsorption after bonding. A spring pin 106 and a window breaking device set in the trigger slot 107 are arranged in the middle of the suction cup 102. Specifically, a spring is arranged inside the spring pin 106. In the default state, the spring pin 106 is tilted against the shell of the trigger slot 107. The conical block at the top of the spring pin 106 is engaged with the bottom of the movable shell at the top of the trigger slot 107. When the shell at the top of the trigger slot 107 is pressed down, the top edge of the conical block of the spring pin 106 is separated from the shell at the top of the trigger slot 107, and then ejected from the hole at the top, hitting the glass to break the glass.

[0035] In order to ensure that the suction cup 102 can be firmly attached to the glass during the process of being sucked together, an adhesive sheet 105 is provided inside the suction cup 102 for balancing, and an adhesive sheet 105 is attached to the surface of the balance column 103. The adhesive sheet 105 is made of glue and is pre-positioned by the balance column 103 after contacting the glass. The balance column 103 is nested with the ring 104. When the suction cup 102 is sucked together, the balance column 103 shrinks into the inside of the ring 104. A limit rod 108 is provided at the bottom of the ring 104. The limit rod 108 has a groove on its surface, which is nested with a releaser 305 inside the limiter 113 at the bottom. The releaser 305 is used to pull to compress the reset spring 114 for energy storage. Since the adhesive sheet 105 is easily covered with dust during daily storage, a protective cover 109 is provided to protect it and avoid the danger caused by the accidental triggering of the spring pin 106.

[0036] The limiting rod 108 is made of metal, and its potential energy can be further increased by adding a suitable weight, so that the trigger slot 107 has improved triggering stability due to the potential energy of the limiting rod 108 when impacting.

[0037] The limiter 113 at the bottom is triggered by controlling the adjusting motor 302. A rotating releaser 305 is arranged on the top of the adjusting motor 302. When the releaser 305 contacts the adjusting slot 304 inside the shell 301, the limit rod 108 is engaged. When the releaser 305 rotates to the area where the adjusting slot 304 has a larger slot, the limit clip 52 inside the releaser 305 is separated from the limit rod 108. A quick connector 303 is arranged at the bottom of the adjusting motor 302. The quick connector 303 is installed at the bottom of the slot body of the fixing seat 112 and is connected to the contacts inside the protective shell 12 to obtain electrical energy to drive the adjusting motor 302 to work. The design of a detachable structure can improve efficiency when replacing multiple window breaking mechanisms.

[0038] In order to facilitate the releaser 305 to be disengaged, three grooves are set in the middle of the rotating column 51 to accommodate the limit clamp 52. The limit clamp 52 uses a metal protective claw 54 to buckle the ball 55. The ball 55 can move inside the protective claw 54. When limiting, the ball 55 can fit tightly with the groove body of the limit rod 108. When it is rotated to a deeper part of the adjustment groove 304, the movable range of the limit clamp 52 becomes larger, and the elastic force of the reset spring 114 is greater than the buckling force of the protective claw 54 on the groove body of the limit rod 108, so that the limit rod 108 is quickly disengaged under the support of the ball 55. In order to prevent the limit clamp 52 from leaning inward and causing the limit rod 108 to be blocked when installed, a reset ring 53 is set to fit the hole position relative to the limit clamp 52 to limit the movement of the limit clamp 52.

[0039] Since the suction cup 102 adopts a suction cup structure, when there is dust on the window, the suction force is reduced. In this regard, the present application is further optimized and adsorption is performed through the adhesive ring 101. Specifically, the adhesive ring 101 adopts a second ring body 1012 made of rubber, and a first ring body 1011 is arranged on the top. The first ring body 1011 is folded outward, and the second ring body 1012 is inclined inward. When subjected to force, the second ring body 1012 is bent inward, and the first ring body 1011 moves along the bending direction of the second ring body 1012. During the movement, the dust is pushed away to reduce floating dust. The outer surface of the second ring body 1012 is provided with a limiting ring 1013 and an adhesive ring 1014. The limiting ring 1013 and the adhesive ring 1014 are used for bonding. When the second ring body 1012 is bent, the adhesive ring 1014 and the limiting ring 1013 are attached to the surface of the glass, wherein the adhesive ring 1014 completely covers the surface of the second ring body 1012. When the first ring body 1011 slides, the adhesive ring 1014 can be attached to the area cleaned by the first ring body 1011.

[0040] Since the second ring body 1012 is made of relatively thin rubber, in order to prevent it from collapsing, a pressing plate 1015 is provided for support. The pressing plate 1015 is made of a metal sheet, and an inlay plate 1016 is provided on the surface. A slot hole that allows the inlay plate 1016 to pass through is provided at the bent part of the inlay plate 1016. When the second ring body 1012 is bent, it can be embedded and then engaged in the slot of the suction cup 102 for biting, thereby preventing the suction cup 102 from falling off due to the reverse thrust generated by the second ring body 1012. In addition, in order to make the second ring body 1012 easier to fold, a plurality of slots 1017 are provided between the second ring bodies 1012 to release stress.

[0041] The improved device controls the puncture part 111 through the limiter 113, stabilizes the suction cup 102 through the balance column 103, and the balance column 103 is pre-bonded to the surface of the glass to form a track with the ring 104. The limit rod 108 uses the potential energy generated by the return spring 114 to push the suction cup 102 to the surface of the glass, and is bonded to the surface of the glass with the cooperation of the adhesive ring 101, so that the trigger groove 107 stably pushes the spring pin 106 to trigger, and the glass is shattered by a single-point breakage method without splashing, thereby improving safety.

[0042] In order to further improve the stability of the bonding surface, the first ring body 1011 is set on the top surface of the second ring body 1012. During the extrusion process, the first ring body 1011 first cleans the surface of the glass, and the adhesive ring 1014 is bonded to the surface of the glass after the second ring body 1012 is bent. Due to the bending and bonding method, the suction cup 102 can generate a negative pressure space during work, thereby improving stability.

[0043] The above only describes the basic principles and preferred implementations of the present invention. Those skilled in the art may make many changes and improvements based on the above description, and these changes and improvements should fall within the protection scope of the present invention.

[0044] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
