Electromagnetic projecting device used for launching fire extinguishing bomb

Abstract

The invention discloses an electromagnetic projecting device used for launching a fire extinguishing bomb. The device comprises a base, a launching frame and an electromagnetic driving device. The launching frame is rotationally connected to the base. The electromagnetic driving device comprises a launching canister, a spring, an electromagnet and a permanent magnet. The launching canister is fixedly connected to the launching frame. One end of the spring is connected with the rear end of the launching canister, and the other end of the spring is connected with the permanent magnet. The electromagnet is fixedly connected to the bottom of the launching canister. The permanent magnet is located in front of the electromagnet in the axial direction. The electromagnet is connected with a power supply circuit. A power source, a current controller and a control switch are arranged in the power supply circuit. Attraction force or repulsion force between the electromagnet and the permanent magnet is controlled based on the current direction and magnitude, and the angle of the launching canister is adjusted by rotating the launching frame, so that the fire extinguishing bomb is projected to a fixed point finally, projection is accurate, operation is convenient, and the effects of suppressing fire and controlling fire spreading are achieved.

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...
