Description

Technical Field

[0001] The invention belongs to the technical field of fire fighting and extinguishing, and in particular relates to a chip induction type fire extinguishing bomb. Background Art

[0002] Fire is a common disaster that has brought serious harm to human society. Fire not only poses a huge threat to life safety, but the damage to property caused by fire cannot be ignored. Fire will not only destroy houses, shops and other buildings, but also burn production equipment, inventory materials, etc., causing huge losses to the economy. When a fire occurs, a large number of police and fire forces are often required to participate in the rescue, causing a shortage of social resources. In order to avoid the spread of fire, it is necessary to use a variety of fire-fighting equipment to extinguish the fire in time.

[0003] In the Chinese patent with the publication number CN208372337U, a new type of pull-ring throwing fire extinguishing bomb is mentioned, including a pull-ring, a copper wire tension spring, and a rectangular outer shell and a cylindrical inner shell. Fire extinguishing powder, a pull-fire cap and an ignition fuse are arranged between the outer shell and the inner shell. The inner shell is filled with pyrotechnics. The pull-fire cap is provided with a copper core ignition agent. The pull-ring is fixed to one end of the copper wire tension spring, and the other end of the copper wire tension spring passes through the outer shell to form a friction portion accommodated in the pull-fire cap. One end of the ignition fuse is adjacent to the pull-fire cap, and the other end of the ignition fuse is connected to the pyrotechnics. It also includes a spare fuse, one end of the spare fuse is adjacent to the ignition fuse, and the other end of the spare fuse passes through the outer shell and extends along the outer wall of the outer shell. The new type of pull-ring throwing fire extinguishing bomb of the utility model is provided with a spare fuse, and the spare fuse can be directly ignited or ignited by high temperature burning on site. The spare fuse cooperates with the pull-ring firing device to form a double insurance to ensure the ignition explosion rate and reduce the occurrence of non-explosion.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example:

[0027] See also Figure 1 - Figure 6 As shown, a chip-sensing fire extinguishing bomb comprises:

[0028] A fire extinguishing bomb box 1, wherein the fire extinguishing bomb box 1 is filled with a fire extinguishing agent that is detonated and spread by an ignition head, and the fire extinguishing bomb box 1 is connected to a mounting plate 2, and the mounting plate 2 is provided with an ignition slot 4 for starting the ignition head;

[0029] A timed starter 5 is connected to the mounting plate 2 and is used to start the fire extinguishing bomb box 1 at a fixed time.

[0034] See also Figure 1As shown, one end of the connecting wire 10 is inserted into the power connection port 14, and the other end is bifurcated into a long branch line connector and a short branch line connector. The long branch line connector is connected to the power connector 8, and the short branch line connector is connected to the safety pin 9. When the connecting wire 10 is disconnected from the timing starter 5, since the short branch line connector is shorter than the long branch line connector, the safety pin 9 will be disconnected before the power connector 8, so that the ignition output connector 7 can be connected to the circuit before the timing starts.

[0035] The buttons 13 include a plus button, a minus button and a SET button. The detonation time can be set within the range of 2S-10S by using the plus button and the minus button. The step can be set to 0.5S, and then the setting can be confirmed by using the SET button. A 3S strobe can be set as a signal of successful setting. When setting the delayed detonation time, you can wait for the start of SET, press the SET button to connect the module, and after the detection module is successfully connected, set the time. After starting the detonation, disconnect the connecting line 10 from the timing starter 5, and then start the delayed ignition and detonation.

[0036] See also Figure 6 As shown, the control circuit includes an MCU controller, a level converter, a decoupling detection connector, a power supply energy storage capacitor, an LDO step-down, a crystal oscillator, an ignition energy storage tantalum capacitor, a thyristor and a safety switch connector. The MCU controller is connected to the level converter through a communication bus, the level converter is connected to the decoupling detection connector, the decoupling detection connector is respectively connected to the ignition energy storage tantalum capacitor and the power supply energy storage capacitor, the power supply energy storage capacitor is connected to the LDO step-down, a 3.3V / 70mA current is connected between the LDO step-down and the MCU controller, the crystal oscillator is connected to the MCU controller, the ignition energy storage tantalum capacitor is connected to the thyristor, the thyristor is connected to the MCU controller and the safety switch connector, the safety switch connector is connected to the ignition output connector 7, and the safety pin 9 is plugged into the safety switch connector.

[0037] During actual operation, the operator can deliver the fire extinguishing bomb through the drone. The timing starter 5 can be installed on the drone, and the drone can then carry the fire extinguishing bomb box 1 to the fire site. The parameters of the timing starter controller 11 can be set through the timing starter 5 and the connecting line 10, and then the fire extinguishing bomb can be released for throwing. During the throwing process, the connecting line 10 is disconnected from the power connector 8 and the safety pin 9 on the timing starter 5, and the fire extinguishing bomb box 1 starts to ignite and detonate.
