The following describes in detail the airborne fire rescue bomb provided by the embodiment of the invention 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 blaster 3. As shown in fig. 2, the load compartment 1 mainly comprises a front end cover 101, a docking ring 102, a shell 103, a hanging rack 114 and a hanging piece 115, the equipment compartment 2 comprises a partition plate 104, a power box 105, a rear end cover 106, two tail wing installation racks 107, eight tail wings 108, a tail wing base 109, a control panel 110, a plug safety 111 and a plugging cover 112, and the blaster 3 comprises a blasting powder installation cover 113, a blasting powder installation pipe 116 and a central blasting powder column 117. The loading cabin 1 is the front 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, and the blaster 3 provides blasting dispersion kinetic energy for the fire extinguishing agent and is positioned in the loading cabin.
As shown in fig. 2, the control board 110 is electrically connected to the plug safety 111, and the plug safety 111 mainly functions to send a trigger signal to the delay fuse. Specifically, the trigger signal carries a delay time, and in the embodiment of the invention, the delay time is determined according to a vertical distance between an aircraft and a target fire scene, for example, when the target fire scene is a forest, the target fire scene is a crown in the forest, at the moment, the delay time is a time when a rescue bomb freely falls from the aircraft to the upper space of the crown and is 10-20 meters away from the crown, and when the target fire scene is a city building, the target fire scene is a building roof, at the moment, the delay time is a time when the rescue bomb freely falls from the aircraft to the upper space of the building roof and is 10-20 meters away from the roof. Further, a time delay fuse is disposed within the central explosive column 117.
In the embodiment of the invention, the plug-in safety has two working states, one is in an electric connection state with the control panel, and the other is in an electric disconnection state with the control panel. In order to control the working state of the plug insurance, preferably, a movable insulating sheet is arranged in the plug insurance 111, the movable insulating sheet is arranged in the plug insurance 111 through a spring piece, when the movable insulating sheet is arranged in the plug insurance 111, the plug insurance 111 cannot send a trigger signal to a delay fuse arranged in the central blasting grain 117 when the movable insulating sheet is arranged in the plug insurance 111, and when the movable insulating sheet is taken out from the plug insurance 111, the plug insurance and the control board establish an electrical connection relationship, and the plug insurance 111 can send the trigger signal to the delay fuse arranged in the central blasting grain 117. Further, when the delay fuze in the central blasting grain 117 receives the trigger signal, starting timing, and when the delay fuze timing is finished, the fuze detonates the central blasting grain 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, and if the delay time is 11 seconds, the timing time of the delay fuse is 11 seconds. In the embodiment of the present invention, the timing time of the extension fuze is not particularly limited.
In practical application, in order to enable the fire extinguishing agent in the rescue bomb to fly around and downwards cover, a circular effective fire extinguishing area is formed. Preferably, the central blasting grain 117 is arranged on a central shaft in the shell 103, and the shell 103 is uniformly filled with fire extinguishing agent around the central blasting grain 117, namely, when the central blasting grain 117 is detonated by a delay fuse arranged on the central blasting grain 117, the central blasting grain 117 in the center of the shell can detonate the fire extinguishing agent distributed around the central blasting grain 117, so that the power is provided for the fire extinguishing agent, the problems that the existing fire extinguishing agent is scattered in a free falling way, the dispersion effect is greatly influenced by air flow, and the unit fire extinguishing agent concentration is uneven are avoided.
In the embodiment of the invention, the movable insulating sheet arranged in the plug safety 111 is moved out of the plug safety 111, so that the electrical connection between the plug safety 111 and the control panel is established, and the control of the controller on the extension fuse is realized. In practical application, only when the rescue bomb falls from the aircraft, the movable insulating sheet can move out of the plug safety 111, namely when the rescue bomb falls from the aircraft, the controller is further electrically connected with the delay fuse through establishing an electrical connection relationship with the plug safety, so that a trigger signal can be sent to the delay fuse, and the delay fuse can determine the timing time according to the delay time because the trigger signal carries the delay time, so that the blasting time of the central blasting grain 117 positioned in the center of the rescue bomb shell is controlled, namely the blasting position of the rescue bomb above a target fire scene is controlled, and the fire extinguishing agent dispersion is controlled.
In the embodiment of the invention, the vertical distance between the aircraft and the target fire scene can be measured by the laser range finder, and the falling speed of the rescue bomb can be calculated by further combining data such as the gravity acceleration of the rescue bomb body, the negative acceleration caused by the air resistance and the like, calculating the aerodynamic characteristics of the rescue bomb body and counting a large amount of test data by utilizing a differential equation. And calculating the time for the rescue bullet to fall to the height of the target fire scene according to a time and speed formula (time=distance/speed) by using the falling speed of the rescue bullet and the vertical distance between the aircraft and the target fire scene, wherein the time is the time delay from the rescue bullet to the time delay fuze triggering the blaster 3 after being put in. The automatic processing function of the computer program is realized through a software program, and the computer program is embedded into a carrier computer. When in practical application, the system automatically sets the time to the time delay fuze, the height of the aircraft is randomly adjusted by ground control personnel according to the needs of fire development, and the time of the fixed-height blasting of the emergency rescue bomb is automatically updated and is completely intelligent. The ground personnel only need to determine the working state of the delay fuze and issue a throwing instruction to finish the throwing work of the emergency rescue bullets.
