Because the forest fire extinguishing bomb needs to be mounted on the aircraft, when the aircraft puts in the forest fire extinguishing bomb, the forest fire extinguishing bomb can be accurately detonated when the distance between the forest fire extinguishing bomb and the crown is 10-20 meters away from the crown by controlling the flight height of the aircraft according to the detonation time of the forest fire extinguishing bomb and the current distance between the forest fire extinguishing bomb and the crown, and the forest fire extinguishing bomb can be ensured to have a good dispersion effect; moreover, when the forest fire extinguishing bomb is used, the bomb body is broken by the power of a rocket engine transversely installed inside, the free dispersion of the fire extinguishing agent is sequentially realized, the fire extinguishing agent freely falls and scatters after the forest fire extinguishing bomb is opened, the forest fire extinguishing bomb belongs to passive dispersion, the dispersion effect is greatly influenced by airflow, and the fire extinguishing agent or the scattering is faster, so that the unit fire extinguishing concentration is reduced, or the forest fire extinguishing bomb reaches the tree crown position without scattering.
In conclusion, the existing forest fire extinguishing bomb has the problems that the detonation position needs to be controlled through the flying height of an aircraft and the unit concentration of the fire extinguishing agent is uneven because the detonation time is fixed and the fire extinguishing agent is free to disperse.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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.
Fig. 1 is a schematic top view of an airborne fire rescue bomb provided in an embodiment of the present invention, and fig. 2 is a schematic structural view of the airborne fire rescue bomb provided in the embodiment of the present invention. The airborne fire rescue bomb provided by the embodiment of the invention is described in detail below with reference to fig. 1 and 2.
As shown in fig. 1, the rescue bomb mainly comprises a load cabin 1, an equipment cabin 2 and a blasting device 3. As shown in fig. 2, the load compartment 1 mainly includes a front cover 101, a docking ring 102, a housing 103, a hanger 114, and a pendant 115; the equipment cabin 2 comprises a partition plate 104, a power supply box 105, a rear end cover 106, two tail mounting frames 107, eight tail pieces 108, a tail base 109, a control panel 110, a plug fuse 111 and a plugging cover 112; the blasting machine 3 includes a blasting agent installation cap 113, a blasting agent installation tube 116 and a center blasting agent column 117. Wherein, the load cabin 1 is the first half part of the rescue bomb and mainly provides a large enough filling space for the fire extinguishing agent; the equipment cabin 2 is the rear half part of the rescue bomb; the blasting machine 3 provides blasting dispersion kinetic energy for the fire extinguishing agent, and the blasting dispersion kinetic energy is located in the load cabin.
As shown in fig. 2, the control board 110 is electrically connected to the plug fuse 111, and the plug fuse 111 mainly functions to send a trigger signal to the delay fuse. Specifically, the trigger signal carries delay time, and in the embodiment of the invention, the delay time is determined according to the vertical distance between the aircraft and the target fire scene, for example, when the target fire scene is a forest, the target fire scene is a crown in the forest, and at the moment, the delay time is the time when the rescue bomb arrives above the crown from the free falling body on the aircraft and is 10-20 meters away from the crown; when the target fire scene is an urban building, the target fire scene is a building roof, and at the moment, the delay time is the time when the rescue bomb freely falls from the aircraft to the upper space of the roof and is 10-20 meters away from the roof. Further, a delay fuse is disposed within the central explosive column 117.
In the embodiment of the invention, the plug-pull fuse has two working states, wherein one working state is a state of establishing electric connection with the control board; the other state is a state of being electrically disconnected from the control board. In order to control the working state of the plug fuse, preferably, a movable insulating sheet is disposed in the plug fuse 111, the movable insulating sheet is disposed in the plug fuse 111 through a spring plate, when the movable insulating sheet is disposed in the plug fuse 111, the plug fuse is electrically disconnected from the control board, and the plug fuse 111 cannot send a trigger signal to a delay fuse disposed in the central blasting cartridge 117; when the movable insulation sheet is taken out from the plug fuse 111, the plug fuse is electrically connected to the control board, and the plug fuse 111 may send a trigger signal to a delay fuse disposed in the central blasting cartridge 117. Further, when the delay fuse in the center explosive column 117 receives the trigger signal, the start of timing is started, and when the timing of the delay fuse is ended, the fuse detonates the center explosive column 117. It should be noted that the timing time of the delay fuse is determined according to the delay time carried by the trigger signal, for example, if the delay time is 9 seconds, the timing time of the delay fuse is 9 seconds; if the delay time is 11 seconds, the timing time of the delay fuse is also 11 seconds. In the embodiment of the present invention, the timing time of the extension fuse is not specifically limited.
In practical application, in order to enable the fire extinguishing agent in the rescue bomb to scatter around and cover downwards, a circular effective fire extinguishing area is formed. Preferably, the central blasting powder column 117 is disposed on the central shaft in the housing 103, and the fire extinguishing agent is uniformly filled around the central blasting powder column 117 in the housing 103, that is, when the central blasting powder column 117 is detonated by the delay fuse disposed on the central blasting powder column 117, the central blasting powder column 117 at the center of the housing can detonate the fire extinguishing agent distributed around the central blasting powder column 117, so as to provide power for the fire extinguishing agent, and avoid the problem that the existing fire extinguishing agent is free to fall, the dispersion effect is greatly influenced by airflow, and the concentration of the unit fire extinguishing agent is not uniform.
In the embodiment of the invention, the movable insulating sheet arranged in the plug fuse 111 is moved out of the plug fuse 111, so that the plug fuse 111 and the control board are electrically connected, namely the controller controls the extension fuse. In practical application, only when the rescue bomb falls off the aircraft, the movable insulating sheet can be moved out of the plug-pull fuse 111, namely when the rescue bomb falls off the aircraft, the controller is electrically connected with the plug-pull fuse through the electric connection relationship between the controller and the plug-pull fuse, and further electrically connected with the delay fuse, so that a trigger signal can be sent to the delay fuse, and due to the fact that the trigger signal carries the delay time, the delay fuse can determine the timing time according to the delay time, so that the blasting time of the central blasting explosive column 117 located in the center of the shell of the rescue bomb is controlled, namely the blasting position of the rescue bomb above a target fire scene is controlled, and further the dispersion control of the fire extinguishing agent is achieved.
It should be noted that in the embodiment of the present invention, because the laser range finder mounted on the aircraft can measure the vertical distance between the aircraft and the target fire scene through the laser range finder, and further, in combination with data such as negative acceleration caused by gravitational acceleration and air resistance of the rescue bomb body, the calculation is performed by using a differential equation, the calculation is performed on the aerodynamic characteristics of the rescue bomb body, and a large amount of test data statistics are performed, so that the falling speed of the rescue bomb can be measured. And calculating the time for the rescue bomb to fall to the height of the target fire scene according to a time and speed formula (time is distance/speed) by utilizing the falling speed of the rescue bomb and the vertical distance between the aircraft and the target fire scene, wherein the time is the delay time from the throwing of the rescue bomb to the triggering of the blasting device 3 by the delay fuse. The computer program realizes the automatic processing function through a software program and is embedded into a computer with a carrier. In practical application, the system automatically fixes the time to the delay fuse, the height of the aircraft is adjusted randomly by ground control personnel according to the requirement of fire development, and the fixed-height blasting time of the emergency rescue bomb is also automatically updated, so that the system is completely intelligent. Ground personnel only need confirm the operating condition of time delay fuze, issue the input instruction and can accomplish the input work of emergency rescue bullet.
In practical application, in order to avoid the problem that one hanger 114 has poor balance when fixing the rescue bomb on the aircraft, preferably, the number of the hangers 114 may include two, and correspondingly, the hangers 114 further include two hangers 115, the two hangers 114 are respectively disposed on the outer side of the housing 103, the two hangers 115 are disposed on the inner side of the housing 103, and the hangers 114 and the hangers 115 are connected by nuts. In the embodiment of the present invention, the pylon 114 is fixedly connected to the aircraft by way of the docking ring 102, and after the fixing member inserted into the docking ring 102 is removed, the pylon 114 and the rescue bomb are separated from the aircraft, that is, the aircraft determines whether to eject the rescue bomb by controlling the fixing member.
Further, in order to avoid that the plug fuse 111 fails to send a trigger signal to the delay fuse in a delayed manner, preferably, the number of the plug fuses 111 may include two, the movable insulating sheets disposed in the two plug fuses 111 are both fixedly connected to the aircraft, and the two plug fuses 111 and the two hangers 114 are both located on the same axis.
As shown in fig. 2, the rescue bomb further comprises a front cover 101, a docking ring 102 and a partition plate 104, specifically, the two docking rings 102 are respectively embedded into the two ends of the shell 103, and in order to avoid the docking ring 102 being separated from the shell 103, the docking ring 102 is preferably adhered into the shell 103 by glue. The front end cover 101 and the butt-joint ring 102 embedded in the front end of the shell 103 are screwed on the front end of the shell 103, and a circular vacant position is formed at the front end of the shell 103 after the front end cover 101 is butted with the front end of the shell 103 because the front end cover 101 has the circular vacant position; further, the isolation plate 104 is screwed on the internal butt-joint ring 102 at the rear end of the housing 103 through threads, and in practical application, two fire extinguishing agent injection holes and a protruding hollow cylinder are respectively arranged on the isolation plate 104, wherein the protruding hollow cylinder is located at the center of the isolation plate 104, and the two fire extinguishing agent injection holes are respectively arranged at other positions of the isolation plate 104 and are not overlapped with the positions of the protruding hollow cylinders.
Further, the rescue bomb further comprises a blasting explosive mounting cover 113 and a blasting explosive mounting tube 116, specifically, one end of the convex hollow cylinder facing the front end of the shell 103 is connected with the blasting explosive mounting tube 116, in practical application, the convex hollow cylinder and the blasting explosive mounting tube 116 can be adhered together through glue, the central blasting explosive column 117 is inserted into the blasting explosive mounting tube 116, and as the front end of the shell 103 is provided with the circular vacant site, the front end of the blasting explosive mounting tube 116 extends into the circular vacant site of the front end cover 101, but the blasting mounting tube is not in contact with the front end cover 101, namely, a gap exists between the blasting explosive mounting tube and the front end cover 101. Further, the other end of the convex hollow cylinder is screwed with the explosive mounting cap 113, i.e. the central explosive column 117 can be fixed in the explosive mounting tube 116 through the explosive mounting cap 113.
It should be noted that, in the embodiment of the present invention, since the partition plate is provided with the convex hollow cylinder, and the blasting agent installation tube 116 and the blasting agent installation cover 113 can be arranged in the shell through the convex hollow cylinder, in practical application, the central blasting agent column 117 and the rescue bomb can be separately stored and transported; or the blaster 1 may be stored and transported separately from the rescue bomb. Furthermore, because the fire extinguishing agent filling hole is formed in the isolation plate, in practical application, the fire extinguishing agent and the rescue bomb can be stored and transported respectively.
