All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical scheme of the fire extinguishing bomb system for the unmanned aerial vehicle comprises the following steps:
a drone and at least one fire extinguishing bomb 12, said fire extinguishing bomb 12 being housed in the shelter 6. Wherein, the shelter 6 is provided with an opening at one side, and the lower plate 61 is arranged at the side opposite to the opening.
In order to mount and separate the fire extinguishing bomb 12 from the shelter 6, the fire extinguishing bomb is mainly mounted and thrown by a quick mounting and throwing device.
As shown in fig. 1, the rapid mounting and releasing device comprises a lifting lug 4, a positioning sleeve 2 and an electromagnet 3. Wherein:
the lifting lug 4 is arranged on the tail wing 1 of the fire extinguishing bomb, and the lifting lug 4 is provided with a first opening 41 for embedding or separating the electromagnet 3;
the lower plate 61 is provided with an empty groove for the lifting lug 4 to extend out, and when the lifting lug is in a mounting state, the lifting lug 4 extends out of the lower plate 61 through the empty groove;
the electromagnet 3 is mounted on the outside of the lower plate 61. When the fire extinguishing bomb 12 needs to be thrown, the electromagnet 3 is separated from the opening I41, and the fire extinguishing bomb 12 falls off.
The electromagnet 3 is a through electromagnet and can be inserted into or separated from the first opening 41. Specifically, the electromagnet 3 may include an electromagnet body and a movable rod that penetrates the electromagnet body and moves relative to the electromagnet body so that the movable rod can be inserted into or removed from the first opening 41.
Further, in the above-mentioned case,
as shown in figure 1, the outer side of the lower plate is also fixedly provided with a positioning sleeve 2, and the positioning sleeve 2 can be of a structure in a shape of Chinese character ji. The positioning sleeve 2 is arranged on the periphery of the empty slot, the positioning sleeve 2 is provided with a cavity, the lifting lug 4 penetrates through the empty slot and then extends into the cavity, the positioning sleeve 2 is further provided with a second opening 21 corresponding to the first opening 41, and the electromagnet 3 is embedded into the first opening 41 through the second opening 21.
In order to facilitate the on-off control of the electromagnet 3, the device further comprises an MCU and a relay, wherein the MCU is connected with the relay, and the relay is further connected with the electromagnet 3. The MCU sends an instruction to the relay to control the electromagnet 3 to be switched on or off, so that the movable rod of the electromagnet 3 makes telescopic motion. Specifically, when the electromagnetic coil in the electromagnet main body is electrified, a magnetic field is generated instantly, the magnetic field generates attraction force on the movable rod and pushes the movable rod to a position far away from the electromagnet main body, so that the movable rod is embedded into the second opening 21 and the first opening 41 in sequence; when the electromagnetic coil in the electromagnet main body is powered off, the magnetism of the electromagnetic coil is instantly lost, the attraction force is also lost, the movable rod is restored to the original position, namely the position close to the electromagnet 3 main body, and the movable rod is separated from the first opening 41 and the second opening 21 in sequence.
In order to realize the connection of the fire extinguishing bomb shelter 6 and the unmanned aerial vehicle, the connection is mainly realized through a quick connecting device.
As shown in fig. 2 (a) and 2 (b), the quick connection device mainly includes a first locker 8, a second locker 9, a locking shaft, a cap nut 10, and a locking spring 11. Wherein:
the locker I8 is arranged on an upper plate 62 of the bullet hanging box, the upper plate 62 of the bullet hanging box is fixed above the positioning sleeve 2, and a through hole for a locking shaft to pass through is arranged on the locker I8;
the second locker 9 is installed on the upper plate 7, the upper plate 7 is fixed on the unmanned aerial vehicle, a through hole for the locking shaft to pass through is formed in the second locker 9, and the locking shaft sequentially passes through the first locker 8 and the second locker 9;
the top end of the locking shaft is connected with a cap nut 10, the tail end of the locking shaft is provided with a bulge, and a clamping groove corresponding to the bulge is arranged on the locker II 9.
The locking spring 11 surrounds the locking shaft and has one end abutting against the cap nut 10, and during the process of inserting the locking shaft into the first and second lockers 8 and 9, the locking spring 11 is in a compressed state and has a tendency to return to an initial position.
When shelter 6 is connected with unmanned aerial vehicle, compression locking spring 11 passes locker one 8 and locker two 9 with the locking axle, then rotatory locking axle for protruding lock advances the draw-in groove. When above-mentioned locking axle is not locked, the arch level sets up in the through-hole, and when needing to lock, rotatory locking axle 90, the arch is rotated to vertical position and lock into the draw-in groove by horizontal position.
In order to realize reliable ignition when fire extinguishing bombs are put in, the ignition device is mainly used for realizing reliable ignition. The ignition reliability device is realized by the spring thimble 51 and the conductive copper sheet 42.
As shown in fig. 3, the hanging lug 4 of the tail wing of the fire extinguishing bomb is provided with a convex conductive copper sheet 42, and the convex conductive copper sheet 42 is positioned on the surface of the hanging lug 4 which is not covered by the positioning sleeve 2.
The lower plate 61 is provided with a spring thimble seat 5, a spring thimble 51 is arranged on the spring thimble seat 5, and the spring thimble seat 5 and the spring thimble 51 are positioned in the falling track of the fire extinguishing bomb 12.
After the electromagnet 3 is separated from the first opening 41 and the second opening 21, the pogo pin 51 contacts the convex conductive copper sheet 42 for conduction after a stroke of the free-falling fire extinguishing bomb 12. But the spring force of the pogo pins 51 is small and does not affect the normal drop of the fire extinguishing bomb 12 until it is completely separated from the shelter.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
