Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a fire-fighting bomb storage type automatic ammunition feeding magazine applied to a fire-fighting bomb continuous launching device. Background Technique

[0002] Fire-fighting bombs are used for fire-fighting and have several states such as manual throwing and equipment throwing or launching. In the actual fire-fighting process, using equipment to launch and throw fire-fighting bombs is more common and more in line with the requirements of the fire-fighting site. At present, the fire-fighting bomb launching technology and equipment are constantly being researched and improved. The fire-fighting bomb launching technology and equipment used in the prior art generally include fire-fighting drones, hand-held fire-fighting bomb launching guns, fire-fighting bomb launchers, and fire-fighting bomb launching vehicles. Among them, the fire-fighting bomb launchers and fire-fighting bomb launching vehicles belong to relatively large fire-fighting equipment, with longer ranges and higher launching speeds, and are suitable for fire-fighting operations in a larger range. Fire-fighting bomb launchers usually use gunpowder, high-pressure gas, mechanical elasticity, electromagnetic force, etc. to provide the launching force. Among them, fire-fighting bomb launching vehicles usually are equipped with ammunition storage and launching systems, and can quickly throw and launch fire-fighting bombs at the fire scene. Fire-fighting bomb launching vehicles usually also have other fire-fighting equipment and tools to provide comprehensive fire-fighting capabilities.

[0003] At present, the common problem in the existing fire-fighting bomb launching equipment is insufficient launching capacity. For example, the utility model patent document with the publication number "CN217716138U" and the name "A moving launching mechanism for fire extinguishing balls" discloses a moving launching mechanism for fire extinguishing balls, including a vehicle chassis with an installation cavity inside; a launching rack rotatably installed on the top surface of the vehicle chassis, and a launching tube is installed on the launching rack for loading fire extinguishing balls; the launching rack is connected with a pitching drive structure and a steering drive structure, the pitching drive structure is used to pull the launching rack to rotate, and the steering drive structure is used to drive the launching rack to rotate; the moving device includes a driving component, a first transmission structure and a plurality of wheel assemblies, the first transmission structure is arranged in the installation cavity, the driving component is connected with the first transmission structure, and the wheel assemblies are arranged on the lower outer side of the vehicle chassis and part of them are connected with the first transmission structure; the driving component drives the wheel assemblies to rotate to drive the vehicle chassis to move. The number of fire extinguishing balls loaded in the launching tube in this comparative document is limited, and the loading rotation and continuous launching of fire extinguishing balls cannot be realized, so its launching capacity is insufficient.

[0004] In addition, the invention patent publication document with the publication number "CN115235291A" and the name "A fully automatic fire extinguishing rocket launcher and launching method" discloses a fully automatic fire extinguishing rocket launcher and launching method. The launcher includes a control system, a base, a launching mechanism, and a loading mechanism; two iron hoops are arranged on the outer circle of the fire extinguishing rocket body, and an annular impact electrode sheet is arranged between the two iron hoops; the loading mechanism includes a rotating wheel, which rotates under the drive of a rotating wheel drive mechanism, and a number of positioning grooves are evenly arranged on the outer circle of the rotating wheel; a magnet groove is arranged at the bottom of the positioning groove; the launching mechanism includes a launching limit plate, and a pitching adjustment unit, a swinging unit, and a rotating unit are sequentially arranged from top to bottom at the lower end of the launching limit plate; a magnet groove for accommodating the iron hoop and an electrode groove for accommodating the impact electrode sheet are arranged on the launching limit plate, and an electromagnet is arranged at the bottom of the magnet groove. This comparative document realizes continuous ammunition supply through the loading mechanism and uses an electromagnet to attract and release the fire extinguishing ammunition to achieve automatic launching. Although the scheme disclosed in the comparative document can realize continuous ammunition supply, its launching ability is limited and it cannot truly complete the fire extinguishing launching task of hundreds of fire extinguishing ammunitions concentrated at one time. It cannot achieve instant rapid launching, continuous launching of a specified number of ammunitions, continuous launching within a specified time, and simultaneous launching of multiple ammunitions, etc., for large-scale launching.

[0005] In summary, it is of great significance to propose a fire extinguishing ammunition storage type automatic ammunition supply magazine in the art that can realize continuous ammunition supply of hundreds of fire extinguishing ammunitions at one time, and can realize single-shot firing, continuous firing, and simultaneous firing of a large number of fire extinguishing ammunitions. Utility Model Content

[0006] Aiming at the deficiencies of the prior art, the present utility model provides a fire extinguishing ammunition storage type automatic ammunition supply magazine, which includes a magazine body. Multiple ammunition clips are arranged in the magazine body, and there is an ammunition clip throwing port at one end of the magazine body; it also includes a pushing unit and a releasing unit. The pushing unit can act on the ammunition clip and push the ammunition clip to move along the X direction towards the ammunition clip throwing port. The releasing unit acts on the ammunition clip and provides a force to resist the gravity of the ammunition clip. When the ammunition clip is located at the ammunition clip throwing port, the releasing unit releases the force to make the ammunition clip move out of the ammunition clip throwing port due to its own gravity.

[0007] Further, a guide rail extending along the X direction is laid on the side of the magazine body. A slider that cooperates with the guide rail is connected to the side of the ammunition clip. The end of the guide rail has a vacant section, and the vacant section forms the ammunition clip throwing port, and the ammunition clip can move out of the vacant section due to its own gravity.

[0008] Further, the pushing unit acts on the side of the ammunition clip and includes a pushing cylinder. The movable end of the pushing cylinder is connected to a push plate. A stop block is connected to the side of the ammunition clip. The movable end of the pushing cylinder can drive the push plate to act on the stop block and push the ammunition clip to move along the X direction.

[0009] Furthermore, the stroke of the pushing unit is a reciprocating motion and can act on each magazine. A spring seat is connected to the side of each magazine. The stopper is located within the spring seat. One side of the stopper facing the magazine ejection port is beveled. A spring is connected between the bottom of the stopper and the bottom surface of the spring seat. When the push plate acts on the beveled surface of the stopper in the reverse X direction, the spring is compressed so that the stopper is received inside the spring seat.

[0010] Furthermore, the pushing unit acts on the first magazine. One end of the push plate has comb teeth. The stopper is provided with a through groove that mates with the comb teeth, so that the stopper is spaced into tooth blocks that mate with the comb teeth. The tooth blocks and the comb teeth constitute the release unit. When the tooth blocks and the comb teeth are in meshing contact, a force is generated to resist the gravity of the magazine. When the tooth blocks and the comb teeth are separated, this force is released.

[0011] Furthermore, a buckle is also connected to the side of the magazine. Two adjacent magazines can be meshed and connected along the X direction through the buckle to slide together, and the buckles can be separated from each other along the direction of magazine falling.

[0012] Furthermore, a back-off limiting member is also connected inside the magazine body. The back-off limiting member can act on each magazine to prevent all magazines from moving in the opposite direction along the X direction.

[0013] Furthermore, the back-off limiting member is a return-preventing and spring-returning stopper deployed on the side guide rail of the magazine body. The number of return-preventing and spring-returning stoppers matches the number of magazines. The relative sliding direction X of the return-preventing and spring-returning stopper with respect to the magazine is beveled. A spring is installed at the bottom of the return-preventing and spring-returning stopper. The distance between adjacent return-preventing and spring-returning stoppers is the same as the width W of the magazine. The return-preventing and spring-returning stopper can act on the slider on the side of each magazine to prevent the magazine from moving in the opposite direction along the X direction.

[0014] Alternatively, the pushing unit acts on the last magazine, and the release unit is an electric flap connected to the magazine ejection port.

[0015] Furthermore, the magazine has conductive contacts.

[0016] Compared with the prior art, the technical solution of the present application has the following beneficial effects: The fire bullet storage type automatic feeding magazine proposed by the present utility model can accommodate multiple magazines arranged in a row. Each magazine can accommodate multiple fire bullets. The continuous supply and removal of the magazines are realized by using the pushing unit and the release unit, thereby providing a sufficient storage type feeding source for the continuous firing of fire bullets and the one-time batch firing of hundreds of fire bullets, greatly improving the firing ability of fire bullets.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] As Figures 1 to 3 shown. A fire bullet storage type automatic ammunition feeding magazine includes a magazine body 11, a plurality of magazines 12 are arranged in the magazine body 11, and a magazine ejection port 13 is provided at one end of the magazine body 11; it further includes a pusher unit 14 and a release unit. The pusher unit can act on the magazine 12 and push the magazine 12 to move along the X direction towards the magazine ejection port 13, and the release unit acts on the magazine 12 and provides a force to resist the gravity of the magazine 12. When the magazine is located at the magazine ejection port 13, the release unit releases the force to make the magazine 12 move out from the magazine ejection port 13 due to its own gravity.

[0030] In this embodiment, the magazine body 11 is a frame structure similar to a rectangle, and a plurality of magazines 12 are arranged in a straight line inside it. The magazines 12 can accommodate a plurality of fire extinguishing cartridges in a matrix array. In order to enable the storage-type automatic ammunition feeding magazine to achieve continuous ammunition feeding, after the first magazine 12 is removed from the magazine ejection port 13 by the release unit, the pushing unit 14 can immediately move the remaining magazines 12 along the X direction towards the magazine ejection port 13. As Figure 6 shown, in order to fire the fire extinguishing cartridges in the magazine 12, the first magazine 12 will contact the firing tube 15 located in front of the magazine ejection port 13 when it reaches the magazine ejection port 13. In this embodiment, the fire extinguishing cartridges are electrically fired, so the firing tube 15 and the magazine 12 are respectively provided with cooperating conductive contacts 151 and conductive contacts 128. After the two come into contact, a firing circuit is formed between the firing tube 15 and the magazine 12. Each fire extinguishing cartridge can be independently powered by this firing circuit, so rich firing operations such as continuous firing, single-shot firing, and multiple-shot firing of the fire extinguishing cartridges in the magazine 12 can be achieved. When the first magazine 12 is emptied, the release unit releases the gravity restriction, the magazine 12 is removed from the magazine ejection port 13, and the pushing unit 14 pushes the subsequent magazine arrangement to move along the X direction towards the magazine ejection port 13 to continue the subsequent firing. Therefore, all the magazines 12 in a fire extinguishing cartridge storage-type automatic ammunition feeding magazine can achieve continuous ammunition feeding and magazine removal operations, undoubtedly improving the firing ability of the fire extinguishing cartridges.

[0031] In a more preferred embodiment, guide rails 111 extending along the X direction are laid on both sides of the magazine body 11. A slider 121 cooperating with the guide rails 111 is connected to the side of the magazine 12. The end of the guide rail 111 has a vacant section 112, and the vacant section 112 forms the magazine ejection port 13. The magazine 12 can be removed from the vacant section 112 due to its own gravity. In this embodiment, the magazine 12 is a flat cuboid structure, and the slider 121 is connected to the magazine 12. By using the cooperation of the slider 121 and the guide rails 111, the magazine 12 can move along the X direction on the surface of the guide rails 111. The guide rails 111 are installed on both sides of the magazine body 11, and their length is shorter than the length of the entire magazine body 11. Therefore, there will be a vacant section 112 at the end of the guide rails 111. When the magazine 12 slides to this vacant section 112 through the slider 121, it has a tendency to fall and be removed due to its own gravity. At this time, the release unit restricts the fall and removal of the magazine 12. When the release unit releases the restriction, the magazine 12 will fall and be removed from the vacant section 112 due to its own gravity.

[0032] As Figure 8 and Figure 9As shown. In a more preferred embodiment, the pushing unit acts on the side of the magazine 12 and includes a pushing cylinder 141. The movable end of the pushing cylinder 141 is connected to a pushing plate 142. A stopper 122 is connected to the side of the magazine 12. The movable end of the pushing cylinder 141 can drive the pushing plate 142 to act on the stopper 122 and push the magazine 12 to move in the X direction. In this embodiment, the pushing unit 14 is fixedly arranged in pairs on the side of the magazine body 11 through a mounting seat 144. The mounting seat 144 is connected to a guiding rod 145. The pushing plate 142 can move in the X direction under the guiding action of the guiding rod 145. When the pushing plate 142 contacts the stopper 122, the magazine 12 can be pushed to move in the X direction.

[0033] In a preferred embodiment, the stroke of the pushing unit 14 is a reciprocating motion and can act on each magazine 12. A spring seat 123 is connected to the side of each magazine 12. The stopper 122 is located inside the spring seat 123. One side of the stopper 122 facing the magazine ejection port 13 is an inclined surface. A first spring 124 is connected between the bottom of the stopper 122 and the bottom surface of the spring seat 123. When the pushing plate 142 acts on the inclined surface of the stopper 122 in the reverse direction of the X direction, the first spring 124 is compressed so that the stopper 122 is pressed back into the spring seat 123.

[0034] In this embodiment, since the pushing unit 14 is a reciprocating motion, during the retraction process of the pushing cylinder 141, it cannot generate a reverse acting force in the X direction on the subsequent magazine 12 to cause the magazine 12 to be retracted. Therefore, the structure of the stopper 122 is optimized. When the pushing plate 142 normally pushes in the X direction, the non-inclined surface ends of the pushing plate 142 and the stopper 122 contact to generate a force in the X direction and apply it to the magazine 12. When the pushing plate 142 retracts, since one side of the stopper 122 facing the magazine ejection port 13 is an inclined surface, at this time, under the contact between the pushing plate 142 and this inclined surface, the stopper 122 will be compressed into the spring seat 123. At this time, the pushing plate 142 can smoothly retract from above the stopper 122 to the side of the stopper 122 away from the magazine ejection port 13. During this process, the stopper 122 will always be compressed into the spring seat 123. When the pushing plate 142 retracts until it leaves the stopper 122, under the action of the first spring 124, the stopper 122 rebounds out. At this time, the pushing plate 142 can continue to apply a pushing force to the stopper 122 in the X direction.

[0035] It should be noted that the function of the releasing unit is to provide a supporting force to the magazine 12 when the magazine 12 is located at the magazine ejection port 13 to resist the gravity of the falling magazine 12. In the above embodiments, the releasing unit can be an independent structure. For example, it can be an electric flap connected to the magazine ejection port 13.

[0036] Such as Figure 7 and Figure 8As shown. On the basis of the above-described embodiment, the release unit is integrated into the pushing unit 14. The pushing unit acts on the first magazine 12. One end of the push plate 142 has comb teeth 143. The stopper 122 is provided with a through groove 125 that cooperates with the comb teeth 143, so that the stopper 122 is spaced into tooth blocks 126 that cooperate with the comb teeth 143. The tooth blocks 126 and the comb teeth 143 constitute the release unit. When the tooth blocks 126 and the comb teeth 143 are in meshing contact, a force that resists the gravity of the magazine 12 is generated. When the tooth blocks 126 and the comb teeth 143 are separated, this force is released.

[0037] As Figure 3 , Figure 8 and Figure 9 As shown, during the process of pushing the magazine 12 in the X direction until it reaches the magazine ejection port 13, the tooth blocks 126 and the comb teeth 143 are in meshing contact. Since the comb teeth 143 are connected to the push plate 142, that is, one end of the comb teeth 143 is open and the other end is closed by the push plate 142. At this time, after the tooth blocks 126 and the comb teeth 143 are meshed, the tooth blocks 126 will still contact the push plate 142 to generate a force in the X direction to make the magazine 12 move. When the magazine 12 reaches the magazine ejection port 13, if the push plate 142 retracts at this time, the comb teeth 143 and the tooth blocks 126 will separate from each other, thus ending the supporting force on the magazine 12. Then the magazine 12 is removed from the magazine ejection port 13 due to its own gravity. During the process of the pushing unit 14 retracting and rehooking the next magazine 12, the previous magazine 12 has been removed. Therefore, the time for continuous feeding can be saved and the structure is simplified. And using the release unit of the electric flap as the magazine 12 ejection mechanism, its release speed is slower than that of this embodiment, but the electric flap can be used as the on-site clearance mechanism for ejecting the magazine 12.

[0038] In the above-described embodiment, if the pushing unit 14 acts on the first magazine 12 every time and there is only one set of the pushing unit 14, then it is desired that the first magazine 12 can drive other subsequent magazines 12 to move synchronously after being pushed. Therefore, a buckle 127 is also connected to the side of the magazine 12. Two adjacent magazines 12 can be meshed and connected along the X direction through the buckle 127, and the buckles can be separated from each other along the falling direction of the magazine 12. Under this structure, the arrangement of the magazines 12 is connected in series by the buckles 127 between them, so they can move synchronously. However, in order not to affect their falling due to gravity, the buckles 127 can be separated from each other in the falling direction. Typically, the buckle 127 is an L-shaped buckle with openings at both ends along the falling direction.

[0039] In a more preferred embodiment, since the arrangement of the magazine 12 requires one-way movement along the X direction, when the pushing unit 14 retracts, it is not desirable for the magazine 12 to retract due to friction. Although the friction between the magazine 12 and the guide rail 111 can prevent this phenomenon to a certain extent, when the magazine body 11 has a certain elevation angle due to actual firing, the magazine 12 may still retract. To avoid this phenomenon, a retraction limiting member 16 is further connected inside the magazine body 11, and the retraction limiting member 16 can act on each magazine 12 to prevent the magazine 12 from moving in the opposite direction along the X direction.

[0040] When an electric flap is used as the release mechanism, since it is independent of the pushing unit 14, the pushing unit 14 can act on the last magazine 12, and all the magazines 12 can be moved along the X direction towards the magazine ejection port 13 through the last magazine 12. At this time, the pushing unit 14 only needs to make a step-by-step push along the X direction, pushing a distance equal to the width of one magazine 12 at a time. In this way, the magazines 12 do not need to be connected in series with each other, nor do they need to additionally use a retraction limiting member 16 to limit the reverse retraction of the magazines 12, because the last magazine 12 is continuously resisted by the pushing unit 14 before being removed.

[0041] As Figure 10 and 11 shown. The retraction limiting member 16 is a non-return spring block 161 deployed on the side guide rail 111 of the magazine body 11. The non-return spring blocks 161 match the number of magazines 12. The non-return spring block 161 has an inclined surface relative to the sliding direction X of the magazine 12. A second spring 163 is installed at the bottom of the non-return spring block 161. The distance between adjacent non-return spring blocks 161 is the same as the width W of the magazine 12. The non-return spring block 161 can act on the slider 121 on the side of each magazine 12 to prevent the magazine 12 from moving in the opposite direction along the X direction.

[0042] In this embodiment, the non-return spring block 161 is installed in a second spring seat 164, and the second spring seat 164 is embedded on the surface of the guide rail 111. When the magazine 12 slides along the X direction, the slider 121 will compress the second spring 163 through contact with the non-return spring block 161. When the non-return spring block 161 is completely embedded in the second spring seat 164, the slider 121 can smoothly pass through the surface of the second spring seat 164 at this time. After the slider 121 completely passes through the non-return spring block 161, the non-return spring block 161 rebounds and resets under the action of the second spring 163, thereby providing a force to limit retraction to the slider 121, and further preventing the magazine 12 from moving in the opposite direction along the X direction.

[0043] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
