Abstract

The invention discloses an electric power sand throwing fire extinguishing device. The electric power sand throwing fire extinguishing device includes a launch cylinder and a sand loading cylinder, the upper end of the sand loading cylinder is open, the sand loading cylinder is placed in the launch cylinder with an open upper end and can movably axially move along the launch cylinder, and the bottom of the sand loading cylinder is connected to the launch cylinder through an ejection mechanism. The ejection mechanism comprises springs, guide rods and a push plate, the push plate is fixedly connected to the bottom of the launch cylinder and is connected to the multiple guide rods through through holes in a sleeving mode, and both ends of the multiple guide rods are fixedly connected into thelaunch cylinder and are arranged circumferentially and uniformly in the length direction of the launch cylinder. The guide rods are sleeved with the springs, one ends of the springs are fixedly connected to the push plate, and the other ends of the springs abut against the launch cylinder. A mechanical switch is arranged at the bottom of the launch cylinder, the mechanical switch can be clamped onto the push plate after the push plate retracts. According to the electric power sand throwing fire extinguishing device, long distance fire extinguishing is achieved, the service safety is improved,and the electric shock hazard is avoided.
