At present, in fire sites such as forests, dangerous chemicals, fuel oil, traffic accidents and the like, different fire extinguishing devices and fire extinguishing modes are required to be used under different geographic environment conditions.

If a fire disaster occurs in a forest or a mountain, the fire extinguishing can not be completed in a short time due to a larger topography, and the forest extinguishing method at the present stage comprises the following steps: water removal in the air, fire extinguishing powder scattering in the air, fire engines, high-pressure fans and manual extinguishing methods.

However, fire extinguishment by any of the above methods requires access to the fire scene. If the forest fire is too large, oxygen is lacking in the center of the fire scene, and when water is scattered in the air, oxygen is added to the fire scene to support combustion. When the fire extinguishing powder is spread in the air, the fire extinguishing powder is far away from a fire source, and the fire extinguishing time is easily missed. When a fire engine is used for fighting a forest fire, the fire engine can only stay at a place with a road in the forest to fight the fire, and the fire engine is difficult to adapt to the needs of the forest fire due to the unfixed nature of the forest fire. The high-pressure fan and forest firefighters can only put out the residual fire in the scene close to the fire disaster.

Moreover, under the condition that forest fire is not pre-warned and reasonably avoided, forest fires easily cause a large range of fire, fire is vigorous and limited by environmental topography, and the aim of effectively extinguishing the fire is difficult to reach by manpower only. Therefore, in order to more reasonably and safely control the fire, fire extinguishing bombs are adopted at the present stage to extinguish the fire in a large range.

As shown in conjunction with fig. 1 and 2, embodiments of the present disclosure provide a fire-fighting electromagnetic fire extinguishing bomb, comprising: a projectile 10, a projectile head 20 and a projectile tail 30, wherein the projectile 10 has a cylindrical structure formed by connecting a plurality of coils; a bullet 20 disposed at a first end of the projectile body 10; a tail 30 disposed at a second end of the projectile body 10; the projectile body 10, the projectile head 20 and the projectile tail 30 are formed with a receiving cavity, and after the fire-fighting electromagnetic fire extinguishing bullet is launched, the connection of adjacent coils is broken to disintegrate the fire-fighting electromagnetic fire extinguishing bullet.

Through improving the projectile body 10, change original integral type projectile body into the tubular structure who forms by a plurality of coils connection, when this fire control electromagnetism fire extinguishing bomb of launching, receive the striking in-process that drops, violent striking can make the junction fracture of coil, and then makes fire control electromagnetism fire extinguishing bomb break, makes the fire extinguishing agent in the fire control electromagnetism fire extinguishing bomb scatter. The fire extinguishing efficiency of the scene can be improved to the greatest extent, and the safety of scene fire-fighting rescue personnel can be further improved.

In this embodiment, the projectile 10, the bullet 20 and the tail 30 are formed with a receiving chamber filled with a fire extinguishing agent, optionally including a gaseous fire extinguishing agent, a liquid fire extinguishing agent or a solid fire extinguishing agent. Suitable fire extinguishing agents can be selected according to actual environmental requirements and use requirements.

In this embodiment, the first end of the projectile body 10 is fixedly connected with the warhead 20, the warhead 20 can play a role in guiding, and the second end of the projectile body 10 is fixedly connected with the tail 30, so that on one hand, a certain buffering effect can be played on the fire extinguishing agent in the accommodating cavity during the launching, and on the other hand, the armatures 100 are also conveniently sleeved, and the fire-fighting electromagnetic fire extinguishing bomb is launched through the armatures 100.

In this embodiment, since the elastic body 10 has a cylindrical structure formed by connecting a plurality of coils, the longitudinal direction of the plurality of coils can withstand electromagnetic overload pressure, and the plurality of coils are easily separated and dispersed by external force in the transverse direction. Therefore, the fire-fighting electromagnetic fire extinguishing bomb is not easy to break in the process of transmitting the fire-fighting electromagnetic fire extinguishing bomb, and the fire-fighting electromagnetic fire extinguishing bomb after falling off can be ensured to break easily.

In the above embodiment, in order to facilitate storage of the fire-fighting electromagnetic fire extinguishing bomb, long-time placement is avoided, and after the fire-fighting electromagnetic fire extinguishing bomb is launched, a "dummy bomb" condition appears, that is, the fire extinguishing bomb is not disassembled, and there is no metal metallographic structure between each coil of the bomb body 10, so as to ensure easy separation and scattering of a plurality of coils which are transversely subjected to external force, wherein the plurality of coils can adopt a connection mode of sequentially bonding, or a connection mode of integrally bonding after stacking and extruding the plurality of coils.

Alternatively, in some embodiments, the projectile 10 is a tubular structure formed by sequentially bonding a plurality of coils. In the process of manufacturing the elastomer 10, each coil of the elastomer 10 is extruded at a high temperature and then a plurality of coils are sequentially bonded to form a cylindrical structure. When the projectile 10 is subjected to a lateral force, the connection of each coil is broken, and the projectile 10 is disassembled.

Alternatively, in some embodiments, the projectile 10 is a tubular structure of a plurality of stacked, extruded connections. In the process of manufacturing the projectile 10, a plurality of coils of the projectile 10 are stacked together, the stacked coils are extruded, the extruded coils are subjected to a high temperature treatment, and finally the extruded coils are fixed by an adhesive or other connecting means to form a tubular structure. When the projectile 10 is subjected to a lateral force, the connection of each coil is still broken, and the projectile 10 is disassembled.

Some existing fire extinguishing bombs have no flame retardant treatment on the projectile body, and after the projectile body is cracked and broken, broken fragments can react with fire, so that the fire extinguishing efficiency can be affected, and even the fire situation becomes large. Alternatively, in some embodiments, the loops of the elastomer 10 include a flame retardant PVC material, a flame retardant metal, a ceramic material, or a glass material. In this way, after the projectile 10 is broken, broken fragments do not react with the fire, and the fragments cover the fire and also play a role in controlling the fire extinguishment.

Alternatively, the projectile 10 is made of a flame retardant metal, including nonflammable metal materials such as copper, iron, aluminum, etc.; alternatively, the projectile 10 is made of a ceramic material or a glass material, has good brittleness, and is more easily damaged after the projectile 10 is dropped to the ground.

Since forest fires are generally sudden events, fire extinguishing agents are usually put into fire extinguishing bombs in advance and stored in order to cope with the sudden events. When needed, the fire extinguishing bomb is directly carried and put into the launching device for use. However, the storage of the fire extinguishing bomb in a short time does not affect the use, and if the fire extinguishing bomb is stored for a long time, the fire extinguishing agent may react with the projectile body of the fire extinguishing bomb, resulting in damage to the fire extinguishing bomb.

Thus, in some embodiments, as shown in connection with fig. 3 and 4, the surface of the warhead 20 is provided with an injection hole 21 communicating with the containing chamber, and the fire extinguishing agent is injected into the containing chamber through the injection hole 21. An injection hole 21 for injecting fire extinguishing agent is provided at the position of the warhead 20, and when the fire extinguishing agent is needed, the fire extinguishing agent is injected into the accommodating cavity of the fire-fighting electromagnetic fire extinguishing bomb through the injection hole 21. Thus, the flexibility of the use of the fire-fighting electromagnetic fire extinguishing bomb is improved; on the other hand, the fire-fighting electromagnetic fire extinguishing bomb has a hollow shell structure before being used, and is convenient to transport and store for a long time.

In this embodiment, the size of the injection hole 21 can be designed according to the shape and size of the warhead 20, for example, the length of the warhead 20 is 20cm, the cross-section is 15cm, and the caliber area of the injection hole 21 can be 4cm ² . Wherein, in order to facilitate the injection of the fire extinguishing agent, the aperture shape of the injection hole 21 can be a round or square shape or other regular patterns。

In this embodiment, when actually needed, in the process of going to the fire scene, the fire extinguishing agent to be used is injected into the accommodating cavity through the agent injection hole 21 in advance, and then the agent injection hole 21 is plugged by the sealing cover.

In some embodiments, the warhead 20 includes a flow guiding portion and a connecting portion, and the injection hole 21 is disposed on a surface of the flow guiding portion, and the connecting portion is fixedly connected to the projectile body 10.

In this embodiment, the warhead 20 comprises two parts, a deflector and a connector. The flow guiding part is streamline, so that air resistance can be effectively reduced in the flight process of the fire-fighting electromagnetic fire extinguishing bomb, and meanwhile, the fire-extinguishing agent hole 21 is also arranged at the position of the flow guiding part, and when the fire-fighting electromagnetic fire extinguishing bomb is launched, according to Newton's law of motion, the fire-extinguishing agent in the accommodating cavity can generate pressure on the tail 30, so that the pressure on the fire-extinguishing agent hole 21 is reduced as much as possible, and the fire-extinguishing agent is prevented from flowing out of the fire-extinguishing agent hole 21.

In some embodiments, the thrust of the launching device is generally against the tail 30, and as shown in connection with FIG. 4, a snap-fit surface 32 is formed at the junction of the tail 30 and the projectile 10. Effectively causes the thrust to act on the clamping face 32 and thus the thrust to act on the whole fire-fighting electromagnetic fire extinguishing bomb.

In this embodiment, the snap-fit interface 32 is created by the size and location of the tail 30 to the projectile 10, and optionally, the cross-sectional diameter of the projectile 10 is greater than the cross-sectional diameter of the tail 30. Thus, the cross-sectional diameter of the projectile 10 is sized differently from the cross-sectional diameter of the tail 30, and the more differently sized face is the snap-fit face 32. Here, the engagement surface 32 may be a vertical plane or may have a slope inclined to one side of the projectile 10.

In some embodiments, as shown in connection with fig. 4 and 6, the tail 30 is provided with a relief surface 31 on the side facing the projectile body 10. During the firing of the fire-fighting electromagnetic fire extinguishing bomb, the instantaneous overload pressure of electromagnetic thrust to the tail 30 can be compensated, and the overload pressure of fire extinguishing agent to the tail 30 can be compensated. Thereby preventing the tail of the electromagnetic shell from being damaged.

In this embodiment, when the fire-fighting electromagnetic fire extinguishing bomb is launched, according to newton's law of motion, the fire extinguishing agent in the accommodating cavity will generate overload pressure on the buffer surface 31 of the tail 30, the diameter expansion of the buffer surface 31 becomes large, and the inner side of the armature 100 will limit the diameter expansion of the buffer surface 31 to become large, so as to prevent the tail 30 of the electromagnetic projectile from being damaged.

In this embodiment, the buffer surface 31 may be a spherical surface, an arc surface, or another form of buffer surface.

The embodiment of the disclosure also provides a fire extinguishing bomb launching device, comprising: a barrel, a solenoid coil and an armature 100. Wherein, the electromagnetic coil is sleeved on the gun barrel; the armature 100 is used for being sleeved on the tail 30 of the fire-fighting electromagnetic fire extinguishing bomb in the previous embodiment. The electromagnetic coil generates thrust to the armature 100, so that the armature 100 pushes the fire-fighting electromagnetic fire extinguishing bomb to advance.

In the above embodiment, the fire extinguishing bomb launcher has a plurality of sets of electromagnetic acceleration launching units, each set of electromagnetic acceleration launching units including an electromagnetic coil 32, a rectifying diode, a power thyristor, an energy storage capacitor, a synchronous trigger control circuit, and the like, to control the electromagnetic coil to generate magnetic force.

Optionally, the synchronous trigger circuit of each electromagnetic accelerating emission unit includes three position detection elements corresponding to the front end, the middle part and the rear end of the electromagnetic coil respectively. Optionally, the synchronous trigger control circuit of each electromagnetic acceleration emission unit includes more than two position detection elements.

Alternatively, for fire-fighting electromagnetic fire extinguishing bombs of greater bulk weight, a multistage tandem electromagnetic coil drive is employed, all electromagnetic coils being coaxially and linearly arranged. The multistage serial electromagnetic coil drives the fire-fighting electromagnetic fire extinguishing bomb to be characterized in that a plurality of coaxial electromagnetic coils are arranged in a straight line, the fire-fighting electromagnetic fire extinguishing bomb passes through the axes of the electromagnetic coils to do straight-line acceleration motion, and finally, the fire-fighting electromagnetic fire extinguishing bomb is emitted out of an electromagnetic muzzle. Because multistage solenoid timesharing circular telegram exerts electromagnetic thrust step by step for fire control electromagnetic fire extinguishing bomb accelerates to the speed of launching that needs step by step, and the transmission process atress is even, and the impact force that fire control electromagnetic fire extinguishing bomb structure received is less, therefore is relatively lower to the requirement of its structure material.

In the above embodiment, as shown in connection with fig. 1 and 7, the armature 100 has a cylindrical structure, and alternatively, the armature 100 is made of aluminum or copper material, forming a solid housing.

In the above-described embodiment, as shown in fig. 1, 8 and 9, the armature 100 has a cylindrical structure, and a support plate for resisting the transverse overload pressure is provided on the inner side of the armature 100. Alternatively, the support plate is an inwardly extending arcuate plate or an arcuate plate that mates with the cushioning surface 31 of the tail 30.

In some embodiments, the extinguishing of forest fires is implemented. A vehicle-mounted manner may be adopted. The control part of the fire extinguishing bomb launching device is a computer control device which is connected with the aiming and measuring assembly and measures the target launching position information such as the height and the distance information in real time. Through the information, the computer control device calculates the driving voltage required by the fire extinguishing bomb launching device and controls the digital controllable high-voltage power supply connected with the computer control device to accurately output the required elevation angle. And then, according to the emission time sequence requirement, the electromagnetic coils are sequentially controlled to be electrified and then powered off, so that the rapid and efficient emission of the fire-fighting electromagnetic fire extinguishing bomb is realized. Optionally, the aiming and measuring assembly is used for acquiring real-time environmental climate information such as wind direction, wind speed, wind temperature and humidity, and calculating the proper fire-fighting electromagnetic fire extinguishing bomb launching speed and launching angle.

In some embodiments, after detecting that each link is ready to be completed, the computer control device sends out a starting signal to control each electromagnetic coil to be electrified, and each electromagnetic coil is instantly electrified to generate strong electromagnetic thrust so as to push the fire-fighting electromagnetic fire extinguishing bomb to move forwards rapidly. When the warhead 20 of the fire-fighting electromagnetic fire extinguishing bomb reaches the entrance of the electromagnetic coil, the position detection element in the synchronous trigger control circuit contained in the electromagnetic drive coil detects the position information of the fire-fighting electromagnetic fire extinguishing bomb and transmits the position information of the fire-fighting electromagnetic fire extinguishing bomb to the control unit of the computer control device, the computer control device gives out a control signal for conducting the electromagnetic coil through calculation and analysis, the control signal is synchronously amplified through the synchronous trigger control circuit and is output to the power thyristor to conduct the electromagnetic coil, at the moment, the energy storage capacitor is conducted with the electromagnetic coil, the energy storage capacitor discharges for the electromagnetic coil, strong current is instantaneously generated, and the electromagnetic coil generates strong electromagnetic force to push the fire-fighting electromagnetic fire extinguishing bomb to continuously accelerate. When the warhead 20 of the fire-fighting electromagnetic fire extinguishing bomb moves to the tail end of the electromagnetic coil, the detecting element at the tail end of the electromagnetic coil detects the position information of the fire extinguishing bomb, and a control signal of outage is transmitted to the computer control device to control the electromagnetic coil to be disconnected with the energy storage capacitor. The electronic thyristors in the assembly are closed through the synchronous trigger control circuit, the electromagnetic coil is powered off, electromagnetic force is not generated any more, reverse electromagnetic pulling force is prevented from being generated by electromagnetic coupling action when the fire-fighting electromagnetic fire extinguishing bomb is driven away from the gun barrel, forward power is counteracted, and forward high-speed movement of the fire-fighting electromagnetic fire extinguishing bomb is influenced. And by analogy, the fire-fighting electromagnetic fire extinguishing bomb sequentially passes through each electromagnetic coil and is continuously pushed to accelerate to advance, so that the required emission speed is reached and the fire-fighting electromagnetic fire extinguishing bomb is shot to the target position.

In some embodiments, the fire extinguishing bomb launching device can be installed on a two-dimensional freedom degree adjusting mechanism which rotates horizontally by 180 degrees and can adjust the elevation angle by 0-70 degrees, wherein the two-dimensional freedom degree adjusting mechanism horizontally rotates and adjusts the fire extinguishing bomb launching device in a gear rotation or motor pulley rolling mode, and the elevation angle is driven in a hydraulic or screw rod mode.

In some embodiments, the fire extinguishing bomb launcher operates as follows, including:

acquiring the position of a target fire extinguishing point;

controlling each electromagnetic coil to be electrified and powered off along the emitting direction of the target fire extinguishing point according to the position of the target fire extinguishing point;

the electromagnetic coil generates electromagnetic force, and the electromagnetic force pushes the fire-fighting electromagnetic fire extinguishing bomb to accelerate.

When the fire-fighting electromagnetic fire extinguishing bomb advances, each control electromagnetic coil is sequentially electrified according to the information of the different positions of the electromagnetic coil, a strong current is instantaneously generated, and the electromagnetic coil generates a strong electromagnetic force which pushes the fire-fighting electromagnetic fire extinguishing bomb to advance in an accelerating way. The electromagnetic coils are sequentially electrified in a segmented time-sharing manner, so that the firefighting electromagnetic fire extinguishing bomb is accelerated gradually, the firefighting electromagnetic fire extinguishing bomb is accelerated to the required emission speed, the electromagnetic conversion efficiency is high, the emission kinetic energy is balanced and stable, and the practicability is good.
