Abstract
A control mechanism of a vehicle-mounted system for electromagnetic launch of fire extinguishing bombs for high-rise buildings is provided. A stress wave amplifier is fixedly connected to a secondary coil, a primary coil is fixedly connected to a coil base, a guide shaft passes through a central hole in the primary coil and the coil base, and a head of the guide shaft is fixedly connected to the secondary coil. A step-up transformer TM1 boosts a 380-V alternating current and changes it to direct current to charge a pulse capacitor C1 and store energy in the pulse capacitor C1. A discharge thyristor M3 is triggered, and the pulse capacitor C1 releases the energy instantaneously. A stress wave is generated between the primary coil and the secondary coil. The stress wave is transmitted to a fire extinguishing bomb through the stress wave amplifier, to launch the fire extinguishing bomb.
