An electromagnetic projectile device for launching fire extinguishing bombs

Abstract

The invention discloses an electromagnetic projectile device for launching fire extinguishing bombs, which comprises a base, a launch frame and an electromagnetic drive device, the launch frame is rotatably connected to the base, the electromagnetic drive device includes a launch tube, a spring, an electromagnet and a permanent magnet, and the launch The barrel is fixedly connected to the launching frame, one end of the spring is connected to the rear end of the launching barrel, and the other end is connected to the permanent magnet. The electromagnet is fixedly connected to the bottom of the launching barrel. The permanent magnet is located in the axial front of the electromagnet. The power supply circuit is provided with a power supply, a current controller and a control switch. The attraction or repulsion between the electromagnet and the permanent magnet is controlled by the direction and magnitude of the current, and the angle of the launch tube is adjusted by the rotation of the launcher, so that the fixed-point projection of the fire extinguishing bomb is finally realized. The projection is accurate and easy to operate, and it can suppress the fire. The role of controlling the spread of fire.

Description

technical field [0001] The invention relates to an electromagnetic projectile device for launching fire extinguishing bombs. Background technique [0002] Where forest fires occur, the mountains are usually relatively steep, the terrain is relatively complicated, and the traffic is relatively difficult, so the work of fighting the fire is very difficult. Once a fire breaks out, it is difficult for ground forces to maneuver quickly to the scene of the fire. At present, long-distance throwing forest fire extinguishing bombs has been used as an effective means of fire extinguishing. By launching fire extinguishing bombs from a long distance, firefighters can avoid close contact with the fire scene and reduce casualties; at the same time, the fire extinguishing bombs are easy to carry, easy to maneuver quickly, and can respond quickly at the first time to suppress the fire in the early stage and control the fire. Spread to buy time to take the next step. [0003] From the per...
