Abstract

The invention discloses a control mechanism of a high-rise building fire extinguishing bomb vehicle-mounted electromagnetic aircraft launch system. The control mechanism is used for solving the technical problem that an existing high-rise building fire extinguishing bomb launching system is poor in practicability. According to the technical scheme, the control mechanism comprises an electronic circuit, a guide shaft, a base, a primary coil, a secondary coil and a stress wave amplifier. The stress wave amplifier is fixedly connected with the primary coil, the primary coil is fixedly connected with a coil base, the guide shaft penetrates through the primary coil and a center hole of the coil base, the head of the guide shaft is fixedly connected with the secondary coil, a boosting transformer TM1 boots 380 V alternating current, through a rectifier bridge, the current is changed into direct current, a pulse capacitor C1 is subjected to charging, energy is stored in the pulse capacitor C1, a discharge silicon controlled rectifier M3 is triggered, the pulse capacitor C1 can instantly release the energy, stress waves are generated between the primary coil and the secondary coil, and aretransmitted to a fire extinguishing bomb through the stress wave amplifier, and the fire extinguishing bomb is shot out. The single-stage launching based on charging and discharging of the capacitoris adopted, control precision is high, and practicability is good.

Description

technical field [0001] The invention relates to a control system, in particular to a control mechanism of a vehicle-mounted electromagnetic ejection system for high-rise building fire extinguishing bombs. Background technique [0002] Fire extinguishing bombs are the main way to solve the problem of fire extinguishing in high-rise buildings, so launching fire extinguishing bombs is the core technology of this technology. The prior art usually adopts hand-throwing launch, gunpowder launch and air cannon launch. The hand-throwing launch is not of high practical value due to the small launch distance; although the gunpowder launch and air cannon launch solve the problem of small launch distance, the launch distance is not adjustable, the repeatability is poor, and there are certain safety hazards, which are easy to cause fire hazards. caused some panic. [0003] The document "Chinese Patent Application Publication No. CN105944262A" discloses an electric launch system for high...
