Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a fire-fighting bomb launching tube for a fire-fighting bomb continuous launching device applied to a fire-fighting bomb storage type automatic feeding magazine. 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 technologies 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 launch vehicles. Among them, the fire-fighting bomb launchers and fire-fighting bomb launch vehicles belong to relatively large fire-fighting equipment, have a longer range and a higher launch speed, and are suitable for fire-fighting operations in a larger range. Fire-fighting bomb launchers usually provide launch force by gunpowder, high-pressure gas, mechanical elasticity, electromagnetic force, etc. Among them, fire-fighting bomb launch vehicles are usually equipped with ammunition storage and launch systems, and can quickly throw and launch fire-fighting bombs at the fire scene. Fire-fighting bomb launch vehicles usually also have other fire-fighting equipment and tools to provide comprehensive fire-fighting capabilities.

[0003] At present, the common problem in the fire-fighting bomb launch equipment in the prior art is insufficient launch capacity. For example, the utility model patent document with the publication number "CN217716138U" and the name "A moving launch mechanism for fire-extinguishing balls" discloses a moving launch mechanism for fire-extinguishing balls, including a vehicle chassis with an installation cavity inside; a launch rack rotatably installed on the top surface of the vehicle chassis, and a launch tube is installed on the launch rack for loading fire-extinguishing balls; the launch rack is connected with a pitching drive structure and a steering drive structure, the pitching drive structure is used to pull the launch rack to rotate, and the steering drive structure is used to drive the launch rack to rotate; the moving device includes a drive assembly, a first transmission structure and a plurality of wheel assemblies, the first transmission structure is arranged in the installation cavity, the drive assembly 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 drive assembly drives the wheel assemblies to rotate to drive the vehicle chassis to move. The number of fire-extinguishing balls loaded in the launch tube in this comparative document is limited, and the loading rotation and continuous launch of fire-extinguishing balls cannot be realized, so its launch 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 electric shock electrode plate 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 electric shock electrode plate 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 at one time. It cannot achieve instant rapid launching, continuous launching of a specified number of ammunitions, continuous launching within a specified time, and multiple ammunitions launched simultaneously in large quantities.

[0005] The applicant hopes to propose a series of improvements to address the problem of insufficient launching ability of fire extinguishing ammunitions commonly existing in the prior art. One of them is to separately design the launching tube and the magazine of the fire extinguishing ammunition. The magazine part adopts a storage-type automatic ammunition supply design, which can realize automatic continuous ammunition supply of the magazine. The launching tube is fixed and only forms a firing electronic control circuit for the fire extinguishing ammunition after the magazine is connected to the launching tube and guides the fire extinguishing ammunition after it is fired. The continuous and batch launching of the fire extinguishing ammunition is realized by connecting the launching tube with the continuously ammunition-supplying magazine, thereby improving the launching ability.

[0006] In summary, it is of great significance to propose a fire extinguishing ammunition launching tube that can achieve the above functions in the art. Utility Model Content

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figure 1 and Figure 2As shown in the figure. A fire bomb launch tube includes a fixed frame 150, a guiding tube 152 is connected inside the fixed frame 150, a contact conductive member is connected to one end of the fixed frame 150, and the contact conductive member is led out by a conductive cable. The contact conductive member is wirelessly connected to a ground remote command station through a controller and a receiver.

[0023] The above forms the basic structural design scheme of the fire bomb launch tube provided by the present invention. The guiding tube 152 is used to provide guidance during the launch of the fire bomb, so that the fire bomb follows a preset trajectory when launched. The fire bomb is electrically fired. When the magazine 12 and the launch tube form a launch circuit, the fire bombs in the magazine 12 can be continuously fired, single-fired, or batch-fired through a corresponding remote wireless control device. Since the launch tube and the magazine 12 are separately designed, the two are in contact and hung through a contact conductive member to form a launch circuit. After the fire bombs in the magazine 12 are launched, the empty magazine 12 is removed, and then the subsequent full magazine 12 is continued to be hung with the launch tube, and the next round of launch can be continued. Therefore, this launch tube makes it possible to continuously launch fire bombs.

[0024] In a more preferred embodiment, the end face of the contact conductive member protrudes or is flush with the end faces of the fixed frame 150 and the guiding tube 152. According to the above description, the launch tube and the magazine 12 are directly in contact and hung to form a conductive circuit, and there are various ways to remove the magazine 12. However, using the self-gravity of the magazine 12 to remove the empty magazine 12 is a fast and economical way, without the need for an additional removal device. Only a supporting force needs to be provided to the magazine 12 that has been hung with the launch tube to form a launch circuit and is ready for launch. And the end face of the contact conductive member protruding or being flush with the end faces of the fixed frame 150 and the guiding tube 152 can ensure that after the conductive member of the magazine 12 contacts the contact conductive member of the launch tube in this embodiment, the two will not form a separation obstacle in the gravity direction of the launch tube and the magazine 12.

[0025] A more preferred embodiment may be as Figure 3 shown. The contact conductive member is a conductive contact 151 connected to the end face of the fixed frame 150. At this time, the conductive contact 128 can be matched for the magazine 12. Obviously, the conductive contact 151 protrudes from the end faces of the fixed frame 150 and the guiding tube 152. After the conductive contact 128 of the magazine 12 contacts the conductive contact 151 to form a launch circuit and the launch is completed, when the magazine 12 needs to be removed by its own gravity, the contact between the conductive contact 128 and the conductive contact 151 can be freely separated without restriction.

[0026] In a more preferred embodiment, the end face of the conductive contact 151 is an inclined plane, and its inclination direction faces the gravity direction of the fixed frame 150. The end face of the conductive contact 151 being an inclined plane can increase its contact area with the conductive contact point 128, making the electrical connection reliability of the emission circuit better. However, the inclination direction of the inclined plane needs to be designed as described above, otherwise it may be unfavorable for the gravity separation of the magazine 12.

[0027] In a more preferred embodiment, as Figure 4 shown, one end of the conductive contact 151 is a telescopic contact 153, and a compression spring 154 is connected between the conductive contact 151 and the telescopic contact 153. When the telescopic contact 153 contacts the conductive contact point 128, the compression spring 154 is compressed by a certain stroke, so that the contact between the telescopic contact 153 and the conductive contact point 128 is tighter and more reliable due to the reverse acting force of the compression spring 154.

[0028] Another embodiment of the contact conductive member can be as Figure 5 shown. The contact conductive member includes a slot 155 connected to the end face of the fixed frame 150. The inner surface of the slot 155 is connected with a contact piece 156. The slot 155 is open along the gravity direction of the fixed frame 150. At this time, the plug 129 on the magazine 12 is matched with the slot 155 to form a firing circuit, and the two are electrically connected in a male-female head matching contact to form a firing circuit. The design that the slot 155 is open along the gravity direction of the fixed frame 150 is to ensure that when the magazine 12 is removed and separated by its own gravity, the separation of the slot 155 and the plug 129 is not restricted.

[0029] In a more preferred embodiment, the middle of the contact piece 156 is warped to form an elastic contact point. This optimized design can, on the one hand, increase the contact area between the contact piece 156 and the plug 129, and on the other hand, increase the contact reliability between the contact piece 156 and the plug 129. It should be noted that the contact friction between the two should not affect the gravity separation of the magazine 12.

[0030] Based on the above embodiments, the guide tubes 152 form a rectangular array, and the number of the contact conductive members matches the number of the guide tubes 152. In this embodiment, there is a 6*6 array of guide tubes 152 in the emission tube. Therefore, after being hooked up with the magazine 12 to form a firing circuit, 36 fire extinguishing projectiles can be launched by a single magazine. When multiple magazines 12 supply ammunition continuously, a large number of fire extinguishing projectiles can be launched.
