Description

Technical Field

[0001] The utility model relates to the field of fire-fighting equipment, in particular to a fire-fighting unmanned helicopter fire-fighting bomb supply device. Background Art

[0002] The fire-fighting unmanned helicopter is a new type of fire-fighting equipment. It uses the drone to carry the loaded fire-extinguishing bombs to high altitudes, and then uses the launch power source on the drone to launch the fire-extinguishing bombs. It can project the fire-extinguishing bombs from the windows of the building into the room, which can reduce the damage caused to firefighters during fire fighting and rescue operations.

[0003] There is a Chinese patent with patent number CN216102784U, which discloses an external bomb-dropping device for a forest fire helicopter, including a delivery clamping box and a cartridge chamber, wherein the cartridge chamber is fixedly arranged at the bottom of the delivery clamping box, and both sides of the interior of the delivery clamping box are provided with fire-extinguishing bomb guide rail cavities, the bottoms of the two fire-extinguishing bomb guide rail cavities are in a connected state, and a movable cavity is provided in the middle of the interior of the delivery clamping box. In this scheme, the ammunition in the fire-extinguishing bomb guide rail cavity is limited by a high-elastic gas column to ensure that the ammunition can enter the cartridge chamber one by one, and the shaking amplitude of the ammunition can be reduced during the ammunition supply process. However, the high-elastic gas column is a soft structure when it is not filled with gas. At this time, the ammunition rolls downward under the action of gravity, and the end of the high-elastic gas column in the soft state is easily pressed into the bottom of the arc-shaped clamping cover, which is easy to cause the ammunition to jam, and there is an obvious deficiency in the smoothness of ammunition supply; in view of this, we propose a fire-extinguishing bomb supply device for a fire-fighting unmanned helicopter that can improve the smoothness of ammunition supply and reduce the shaking amplitude of ammunition. Utility Model Content

[0004] The utility model aims to solve the problems existing in the background technology and proposes a fire-fighting unmanned helicopter fire-fighting bomb supply device which can improve the smoothness of ammunition supply and reduce the amplitude of ammunition shaking.

[0005] The technical solution of the utility model is as follows: A fire-fighting unmanned helicopter fire-fighting bomb supply device comprises an ammunition box, a pre-storage interval is excavated inside the ammunition box, a projection channel is excavated inside the ammunition box and below the pre-storage interval, airbags are placed in the pre-storage interval and near its two inner walls, and a number of fire-extinguishing bombs are placed between the two airbags. A number of first cylinders are fixedly installed in the ammunition box, a partition assembly is fixedly installed at the output end of each of the first cylinders, the bottom end of each of the partition assemblies is inserted into the pre-storage interval, and each partition assembly is located between two adjacent fire-extinguishing bombs. Two second cylinders are fixedly installed in the ammunition box, a limiting assembly is fixedly installed at the output end of each of the second cylinders, and the end of each limiting assembly away from the second cylinder is inserted into the connecting interval between the pre-storage interval and the projection channel.

[0006] Preferably, each of the partition components includes a connecting plate, each of the connecting plates is fixedly connected to the output end of the matching first cylinder, and each of the connecting plates is fixedly installed with a lifting plate at both ends away from each other. Two symmetrically arranged metal springs are welded to the lower surface of each lifting plate, and the lifting plate is driven to move up and down by the first cylinder. When the metal springs move up and shrink to the inside of the cavity at the top of the pre-storage interval, the fire extinguishing bomb can be moved to one side of the projection channel, thereby facilitating the control of the movement of the fire extinguishing bomb.

[0007] Preferably, a number of springs are fixedly installed between two metal shrapnel arranged in the same group, and the arc surface at the bottom of each metal shrapnel fits with the outer wall of the adjacent fire extinguishing bomb. The spring pushes the metal shrapnel to tilt toward one side of the fire extinguishing bomb, and then the fire extinguishing bomb in the pre-stored interval can be clamped and positioned, effectively preventing the fire extinguishing bomb from shaking violently.

[0008] Preferably, each of the limiting components includes a transverse push plate, each of the transverse push plates is fixedly connected to the output end of the matching second cylinder, and each of the transverse push plates has two partition frames fixedly installed on the end away from the second cylinder. The bottom end of each of the partition frames is an arc surface structure. The partition frames can not only separate the fire extinguishing bombs, but also limit the fire extinguishing bombs in the projection channel to prevent them from bouncing upwards when fired.

[0009] Preferably, each of the transverse push plates is provided with two second load-reducing openings, and each of the partition frames is provided with a first load-reducing opening. The weight of the limit assembly can be reduced through the multiple load-reducing openings, and the burden on the second cylinder can be reduced.

[0010] Preferably, two covers are fixedly installed at the top opening of the ammunition box by screws, and each of the covers is located above a matching airbag. The loading opening is blocked by the covers, which can prevent the airbag from popping out of the loading port.

[0011] Preferably, connecting frames are fixedly installed at both ends of the ammunition box away from each other, and one end of each connecting frame away from the ammunition box is fixed to the frame of the drone by screws. The ammunition box can be fixed to the frame of the drone through the connecting frame, and the external mounting structure is convenient for disassembly, assembly and maintenance.

[0012] Compared with the prior art, the utility model has the following beneficial technical effects:

[0013] 1. The partition assembly is driven to move up and down by the first cylinder. When the partition assembly moves down, it can squeeze the fire extinguishing bomb, making it easier to push it into the projection channel. In addition, a limit assembly is provided in the area above the projection channel to prevent two fire extinguishing bombs from stacking together and jamming, thereby effectively improving the smoothness of ammunition supply.

[0014] 2. The separation component can also be used to separate multiple fire-extinguishing bombs in the pre-storage interval. Since the metal shrapnel at the bottom of the separation component is elastic and a spring is installed between two metal shrapnel arranged in the same group, the fire-extinguishing bombs can be clamped. As the number of fire-extinguishing bombs in the pre-storage interval decreases, the fire-extinguishing bombs can be prevented from shaking horizontally in the pre-storage interval, effectively reducing the shaking amplitude of the ammunition.

[0028] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0029] Embodiment 1

[0030] like Figure 1-4 As shown, the utility model proposes a fire-fighting unmanned helicopter fire-fighting bomb supply device, including an ammunition box 1, a pre-storage interval 2 is excavated inside the ammunition box 1, and a plurality of fire-extinguishing bombs 5 are stored inside the pre-storage interval 2. Air bags 7 are placed inside the pre-storage interval 2 and at the positions of the two inner side walls of the opening. When all the fire-extinguishing bombs 5 are placed inside the pre-storage interval 2, the air bags 7 are inserted into the pre-storage interval 2 from the loading port at the top of the ammunition box 1, and the two fire-extinguishing bombs 5 near the loading port can be squeezed by the two air bags 7. A plurality of cavities are excavated inside the ammunition box 1 and above the pre-storage interval 2, and a first cylinder 4 is fixedly installed in each cavity, and a partition assembly is fixedly installed at the output end of each first cylinder 4, and the metal spring 42 at the bottom of the partition assembly is located in the gap between the two fire-extinguishing bombs 5, which can separate the fire-extinguishing bombs 5. A projection channel 9 is also excavated inside the ammunition box 1, and the projection channel 9 is located below the pre-storage interval 2. A connecting channel for the fire extinguishing bomb 5 to fall is excavated between the pre-storage interval 2 and the projection channel 9, ensuring that the fire extinguishing bomb 5 in the pre-storage interval 2 can fall into the projection channel 9. A cavity is excavated inside the ammunition box 1 and on both sides of the connecting channel. A second cylinder 8 is fixedly installed inside the cavity, and a limiting component is fixedly installed on the output end of each second cylinder 8. The partition frame 82 of the limiting component is located inside the connecting channel, which can separate the fire extinguishing bomb 5 in the projection channel 9 and the fire extinguishing bomb 5 that falls into the connecting channel to prevent the fire extinguishing bomb 5 from stacking together.

[0031] The working principle of a fire-fighting unmanned helicopter fire-fighting bomb supply device based on the first embodiment is: first, multiple fire-fighting bombs 5 are stored in the pre-stored interval 2, the bombing amount of the drone is increased, and it is ensured that the drone can carry multiple fire-fighting bombs 5 into the fire scene. When it is necessary to drop the fire-fighting bomb 5 from the pre-stored interval 2 into the projection channel 9, a first cylinder 4 near the projection channel 9 drives the corresponding metal shrapnel 42 to move upward, and when the metal shrapnel 42 shrinks to the inside of the cavity, the first cylinder 4 on its left or right side drives the corresponding metal shrapnel 42 to move downward, at this time, the metal shrapnel 42 will squeeze the adjacent fire-fighting bomb 5, and then push the fire-fighting bomb 5 into the connecting channel to ensure that the fire-fighting bomb 5 can slide into the projection channel 9. At this time, the partition frame 82 is driven by the second cylinder 8 to move into the connecting channel, and then the fire-fighting bomb 5 in the projection channel 9 can be limited to prevent the fire-fighting bomb 5 from bouncing upward when launched. The fire-fighting bomb 5 can be launched from the projection channel 9 by the launch power source installed on the drone. Before the fire extinguishing bomb 5 is reflected, the fire extinguishing bomb 5 in the pre-stored interval 2 can continue to be supplied to the connecting channel, shortening the waiting time for the ammunition supply. At this time, the partition frame 82 can prevent the fire extinguishing bomb 5 in the connecting channel from being stacked with the fire extinguishing bomb 5 in the projection channel 9, and the metal shrapnel 42 can also separate the fire extinguishing bomb 5 in the pre-stored interval 2. The use of a hard partition structure instead of the inflatable elastic gas column can avoid obstruction to the transportation of the fire extinguishing bomb 5 after the gas column is deflated, reduce the probability of the fire extinguishing bomb 5 being stuck, and effectively improve the smoothness of the ammunition supply.

[0032] Embodiment 2

[0033] like Figure 1-4 As shown, the utility model proposes a fire-extinguishing bomb supply device for an unmanned fire-fighting helicopter.

[0034] Reference Figure 3 Each partition assembly includes a connecting plate 44, the upper surface of each connecting plate 44 is welded to the output end of the corresponding first cylinder 4, and the two ends of each connecting plate 44 that are far away from each other are welded with a lifting plate 41. Each lifting plate 41 and the connecting plate 44 are movably installed in the cavity above the pre-storage interval 2. The bottom end of each lifting plate 41 is welded with two symmetrically arranged metal springs 42, and a plurality of springs 43 are fixed between the two metal springs 42 arranged in the same group. The bottom end of each metal spring 42 is a curved surface structure, and the curved surface structure can fit the outer wall of the fire extinguishing bomb 5;

[0035] In this solution, the two lifting plates 41 are connected as one by the connecting plate 44, ensuring that the two lifting plates 41 and the metal shrapnel 42 set in the same group can be lifted and moved synchronously. When the metal shrapnel 42 is inserted into the gap between the two fire extinguishing bombs 5, the two adjacent fire extinguishing bombs 5 can be separated to prevent the fire extinguishing bombs 5 from shaking violently in the pre-stored interval 2. Under the action of the spring 43, the metal shrapnel 42 can be tilted toward the side of the fire extinguishing bomb 5 and provide horizontal thrust to the fire extinguishing bomb 5. When the fire extinguishing bomb 5 loses its limit when it approaches the projection channel 9, the fire extinguishing bomb 5 can be pushed toward the projection channel 9, making it easier to put the fire extinguishing bomb 5 into the projection channel 9.

[0036] Reference Figure 4 Each limit assembly includes a transverse push plate 81, each transverse push plate 81 is movably installed in the cavity on both sides of the connecting channel, the output end of each second cylinder 8 is fixedly connected to the matching transverse push plate 81, and each transverse push plate 81 is welded with two partition frames 82 on the side close to the connecting channel, and the bottom end of each partition frame 82 is provided with an arc surface structure, which fits the outer wall of the fire extinguishing bomb 5 in the projection channel 9. Two second load-reducing openings 84 are drilled on each transverse push plate 81, and a first load-reducing opening 83 is drilled on each partition frame 82;

[0037] In this solution, the second load-reducing opening 84 is cut on the transverse push plate 81, which can reduce the weight of the transverse push plate 81. The first load-reducing opening 83 is cut on the partition frame 82, which can also reduce the weight of the partition frame 82. Therefore, the overall weight of the limit assembly can be reduced, and when the second cylinder 8 drives the limit assembly to move laterally, the burden of the second cylinder 8 can be reduced. After the fire extinguishing bomb 5 falls into the projection channel 9, the two partition frames 82 can limit the fire extinguishing bomb 5, which can prevent the fire extinguishing bomb 5 from bouncing upward during launch, thereby improving its stability during launch. In addition, the partition frame 82 can also separate the two fire extinguishing bombs 5 in the projection channel 9 and the connecting channel to avoid the two fire extinguishing bombs 5 from stacking together, and can prevent the two fire extinguishing bombs 5 at this location from rubbing against each other during launch.

[0038] Reference Figure 1-2 The top of the ammunition box 1 is provided with two loading openings connected to the inside of the pre-storage area 2. A cover 3 is mounted on each loading opening, and each cover 3 is fixed to the top of the ammunition box 1 by screws. The airbag 7 in the pre-storage area 2 is arranged below the cover 3. Connecting frames 6 are welded on two outer walls away from each other of the ammunition box 1, and the top of each connecting frame 6 is fixed to the frame of the drone by screws.

[0039] In this solution, the connecting frame 6 is fixed to the UAV frame by screws to ensure that the ammunition box 1 can be firmly hung under the UAV frame. An external hanging structure is adopted to facilitate the disassembly and assembly of the ammunition box 1. When the ammunition box 1 is removed, it is convenient for loading and maintenance. The loading opening is blocked by the cover 3 to prevent the airbag 7 from popping out from the loading opening, ensuring that the airbag 7 can be stably assembled inside the pre-storage interval 2.

[0040] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
