DETAILED DESCRIPTION

[0026] The embodiments of the present invention are described in detail below. Figures 1 to 5 The embodiment of the present invention provides an intrinsically safe gliding fire-extinguishing bomb, including a fire-extinguishing bomb body 100. Figure 3 The fire-extinguishing bomb body 100 includes a shell 110 and a plasma excitation device 120, a high explosive column 130 and a fire extinguishing agent 140 arranged in the shell 110. The high explosive column 130 is inserted into the fire extinguishing agent 140 and is wrapped by the fire extinguishing agent 140. The plasma excitation device 120 can generate a plasma shock wave to instantly detonate the high explosive column 130 and the fire extinguishing agent 140. The fire-extinguishing bomb can use the plasma excitation device 120 to generate a high-temperature, high-pressure, and high-speed plasma shock wave to directly detonate the high explosive column 130 and the fire extinguishing agent 140, thereby forming a large-area explosion ultra-fine aerosol shock wave, and cooperate with the chemical suppression fire extinguishing mechanism to achieve efficient fire extinguishing. Since the fire-extinguishing bomb uses a pure electric energy to trigger the plasma excitation device 120, the intrinsically safe plasma excitation device 120 is a pure electric energy discharge device. The discharge device can generate a plasma shock wave to detonate the high explosive column 130 and the fire extinguishing agent 140, which can replace the existing traditional detonator fuzes with dangerous explosives that are not intrinsically safe. Therefore, the gliding fire-extinguishing bomb does not need to install dangerous goods detonator fuzes with poor safety and high mechanical sensitivity. It has intrinsic safety in the whole process of production, transportation, storage and deployment, which improves the safety of the fire-extinguishing bomb in the whole process of production, transportation, storage and deployment. For the triggering time of the plasma excitation device 120, it can be achieved by temperature sensing, infrared sensing and shooting image information. The high explosive column 130 can be RDX, TNT, B high explosive or emulsion explosive, and the fire extinguishing agent 140 is a dry powder fire extinguishing agent 140 or a liquid fire extinguishing agent 140.

[0027] Further, refer to Figures 1 to 3The gliding fire-extinguishing bomb also includes an optoelectronic image seeker 200, a tail servo module 300 and a first control module 400. The optoelectronic image seeker 200 is arranged at the head of the fire-extinguishing bomb body 100, the tail servo module 300 is arranged at the tail of the fire-extinguishing bomb body 100, and the first control module 400 is arranged in the fire-extinguishing bomb body 100, and is electrically connected or signal-connected to the optoelectronic image seeker 200, the first control module 400 and the plasma excitation device 120; the optoelectronic image seeker 200 is used to detect the image of the forest fire area and transmit the signal to the first control module 400, and the first control module 400 can control the tail servo module 300 according to the signal of the optoelectronic image seeker 200 to guide the gliding fire-extinguishing bomb to fly to the forest fire area, and control the plasma excitation device 120 to generate plasma shock waves. The gliding fire-extinguishing bomb is provided with an optoelectronic image seeker 200. After being dropped, during the landing flight, the optoelectronic image seeker 200 can detect the image of the forest fire area, and control the tail servo module 300 through the first control module 400 to guide the fire-extinguishing bomb to fly to the forest water area. After flying to the target position, the electric energy stored in the high-voltage capacitor of the first control module 400 is instantly discharged in the central bridge foil of the plasma excitation device 120, generating a high-temperature, high-pressure, and high-speed plasma shock wave, directly detonating the high explosive column 130 and the fire extinguishing agent 140, thereby forming a large-area explosion ultrafine aerosol shock wave, and cooperating with the chemical suppression fire extinguishing mechanism to achieve efficient fire extinguishing.

[0028] The gliding fire-extinguishing bomb is mounted on an aircraft such as a manned helicopter, a fixed-wing aircraft or a large unmanned aerial vehicle and flies to the forest fire site. It is dropped from the air 1.5km to 3km away from the forest fire area. A second control module 500 is arranged in the cockpit of the aircraft, and the second control module 500 is connected to the optoelectronic image seeker 200 or the first control module 400 by signal. After the gliding fire-extinguishing bomb is dropped, in the first gliding stage, that is, the initial descent stage, the pilot manually and wirelessly remotely controls the second control module 500 to control the tail servo module 300 according to the signal of the optoelectronic image seeker 200. In the second gliding stage, that is, the final gliding stage, autonomous optoelectronic image navigation is adopted, and the first control module 400 controls the tail servo module 300 according to the signal of the optoelectronic image seeker 200. Among them, the first gliding stage is the initial gliding stage, and the second gliding stage is the final gliding stage. The gliding fire-extinguishing bomb is provided with an optoelectronic image seeker 200, a first control module 400, and a second control module 500. In the first gliding stage, the pilot can remotely control the tail servo module 300 through the second control module 500, and lock the imaging information at the strongest fire source in real time to guide the gliding fire-extinguishing bomb to fly to the target in the fire area. In the second gliding stage, the first control module 400 can autonomously navigate the image to fly to the fire area and detonate the gliding fire-extinguishing bomb to extinguish the fire. Therefore, the gliding fire-extinguishing bomb can be dropped from the air 1.5km to 3km outside the fire area, thereby ensuring that the aircraft does not need to fly over the forest fire site or project at close range, and can avoid the risk of crashing caused by the inability of the aircraft to effectively control flight due to the violent disturbance of the rising strong hot air flow.

[0029] The tail fins of some fire-fighting bombs in the prior art use controlled or uncontrolled "X"-shaped tail fins with small lift. The fire-fighting bombs with controlled "X" tail fins use a high-cost composite guidance system, with SINS+GNSS guidance used for mid-course guidance and semi-strapdown infrared imaging guidance (strapdown inertial navigation+satellite navigation+semi-strapdown infrared imaging navigation) used for terminal guidance, which is relatively expensive. The fire-fighting bombs with uncontrolled "X" tail fins need to be projected at close range, and due to the violent disturbance caused by the rising of strong thermal air currents, the aircraft may be easily uncontrollable, resulting in a serious accident of a crash. The fire-extinguishing bomb of the present invention adopts pure electric energy plasma impact to detonate high explosives and fire extinguishing agents, a glider wing with large lift force and a low-cost guidance system, so that it can be dropped from the air 1.5km to 3km away from the forest fire area. The pilot's manual wireless remote control navigation is adopted for the initial descent stage guidance, and the fire-extinguishing bomb's autonomous photoelectric image navigation is adopted for the terminal stage guidance, thereby ensuring that the aircraft does not need to fly over the forest fire scene or be dropped at close range, and can avoid the risk of crashing caused by the inability to effectively control the flight of the aircraft due to the violent disturbance of the rising strong hot air flow. At the same time, there is no need to install explosive fuses with poor safety and high mechanical sensitivity. Therefore, it is inherently safe in the whole process of production, transportation, storage and delivery and use, thereby improving the safety of the fire-extinguishing bomb in the whole process of production, transportation, storage and delivery and use.

[0030] Furthermore, the gliding fire-extinguishing bomb also includes a glider module 600, which includes a wing fixing plate 610, a left wing 620 and a right wing 630. The wing fixing plate 610 is arranged on the top of the fire-extinguishing bomb body 100, and the left wing 620 and the right wing 630 are respectively arranged on the left and right sides of the fire-extinguishing bomb body 100. The left wing 620 and the right wing 630 can adopt folding wings. The tail servo module 300 includes a directional servo 310, a pitch servo 320 and a servo control unit 330. The left and right swing angle of the directional servo 310 is α, and the pitch swing angle of the pitch servo 320 is β. The servo control unit 330 is electrically connected or signal-connected to the directional servo 310, the pitch servo 320, the first control module 400 and the second control module 500. The outer cover of the fire-extinguishing bomb body 100, the gliding wing module 600, the tail servo module 300 and the photoelectric image seeker 200 are all made of engineering plastics. The gliding fire-extinguishing bomb controls the flight of the gliding fire-extinguishing bomb through the gliding wing module 600 and the tail servo module 300, so that the gliding fire-extinguishing bomb does not rotate during the delivery and descent process, so the low-cost navigation technology can be used to achieve the precise delivery of the gliding fire-extinguishing bomb.

[0031] Further, refer to Figure 3The first control module 400 includes an intelligent circuit board 410 and a GC-Bus and antenna printed board 420. The intelligent circuit board 410 is electrically connected or signal-connected to the optoelectronic image seeker 200, and the intelligent circuit board 410 is connected to the GC-Bus and the antenna printed board 420 via a two-wire communication bus GC-Bus and a wireless communication radio frequency line. The GC-Bus and the antenna printed board 420 are installed in the fire-extinguishing bomb body 100, and the GC-Bus and the antenna printed board 420 are connected to the steering gear control unit 330 via a two-wire communication bus GC-Bus. The steering gear control unit 330 includes a rudder, a pitch rudder electronic control part and a battery power supply part. The GC-Bus in the GC-Bus and antenna printed board 420 is a two-wire GC-Bus (Guidance control Bus) for digital communication and power supply sharing between the steering engine control unit 330 and the intelligent circuit board 410, wherein the GC-Bus and antenna printed board 420 is a long strip printed circuit board, and the printed circuit board is printed with a two-wire GC-Bus bus and a wireless communication antenna.

[0032] Further, refer to Figure 4 The second control module 500 includes an image microprocessor controller 510, a wireless data communication circuit 520, a display remote control operating system 530 and an electric mounted locking device 540; the first interface, the second interface and the third interface of the image microprocessor controller 510 are respectively connected to the wireless data communication circuit 520, the display remote control operating system 530 and the electric mounted locking device 540, and the wireless data communication circuit 520 is connected to the first control module 400 by signal. Further, the first interface of the image microprocessor controller 510 is connected to the wireless data communication circuit 520, the antenna in the wireless data communication line and the GC-Bus in the gliding fire-extinguishing bomb and the antenna printed board 420 perform wireless data communication, and transmit the image information of the optoelectronic image seeker 200 in the gliding fire-extinguishing bomb and the flight control information of the steering engine control unit 330.

A mounting hole 160 is provided on the top of the fire-extinguishing bomb body 100. When the electromagnetic coil is not energized, the electric latch is inserted into the mounting hole 160 by the action of the spring. When the electromagnetic coil is energized, the electric latch is pulled out of the mounting hole 160, and the gliding fire-extinguishing bomb is launched. There are two electric latches and two mounting holes 160. When launching the gliding fire-extinguishing bomb, the two electric latches are pulled out of the mounting hole 160 at the same time to launch the gliding fire-extinguishing bomb.

[0034] The embodiment of the present invention also provides a method for controlling the delivery of an intrinsically safe gliding fire-extinguishing bomb, comprising the following steps:

[0035] Step S100: The gliding fire-extinguishing bomb is mounted on an aircraft and flies to the forest fire site, and is dropped from the air at a distance of 1.5 km to 3 km from the forest fire area;

[0036] Step S200: In the first gliding stage (initial descent stage), the pilot manually and wirelessly remotely controls the second control module 500 to control the tail servo module 300 according to the signal of the optoelectronic image seeker 200, and locks the imaging information of the strongest fire source in real time, guiding the gliding fire-extinguishing bomb to fly to the forest fire area;

[0037] Step S300, in the second gliding stage (the final gliding stage), autonomous optoelectronic image navigation is adopted, and the first control module 400 autonomously controls the tail servo module 300 according to the signal of the optoelectronic image seeker 200 to guide the gliding fire-extinguishing bomb to fly toward the target in the fire area, and controls the plasma excitation device 120 to generate a plasma shock wave to detonate the high explosive column 130 and the fire extinguishing agent 140.

[0038] Therefore, the gliding fire-extinguishing bomb adopts a pure electric energy-triggered plasma excitation device 120, and does not need to install a dangerous detonator fuse with poor safety and high mechanical sensitivity. Therefore, it is inherently safe in the entire process of production, transportation, storage, and delivery, which improves the safety of the fire-extinguishing bomb in the entire process of production, transportation, storage, and delivery. It can be dropped from the air 1.5km to 3km outside the fire area, thereby ensuring that the aircraft does not need to fly over the forest fire site or project at close range, and can avoid the risk of crashing caused by the violent disturbance of the rising strong hot air flow that causes the aircraft to be unable to effectively control the flight. The gliding fire-extinguishing bomb controls the flight of the gliding fire-extinguishing bomb through the gliding wing module 600 and the tail wing servo module 300, so that the gliding fire-extinguishing bomb does not rotate during the delivery and descent process, so low-cost navigation technology can be used to achieve accurate delivery of the gliding fire-extinguishing bomb.

[0039] After the gliding fire-extinguishing bomb is released, the pilot can remotely control the tail servo module 300 through the second control module 500 in the first gliding stage, and lock the imaging information of the strongest fire source in real time to guide the gliding fire-extinguishing bomb to fly to the target in the fire area. In the second gliding stage, the first control module 400 can autonomously navigate the image to fly to the fire area and detonate the gliding fire-extinguishing bomb to extinguish the fire. Therefore, the gliding fire-extinguishing bomb is an intrinsically safe, low-cost, easy-to-control gliding fire-extinguishing bomb that can be released over a long range and can accurately and quickly extinguish fires in forest areas.
