The invention discloses an intelligent dense shelf, comprising a main box body and an auxiliary box body, the main box is arranged on the right side of the auxiliary box body, a main separation chamber and a main storage chamber are arranged in that main box body. The auxiliary box body is provided with an auxiliary object chamber and an auxiliary separation chamber, a separation motor is arrangedin the main separation chamber, the
motor shaft of the separation motor is fixedly connected with a separation screw which is matched with the auxiliary separation chamber,
smoke sensors are arrangedat the top ends of the inner cavity side walls of the main object chamber and the auxiliary object chamber, and the separation motor is respectively connected with all
smoke sensors. As the
smoke sensor sense the fire, the smoke sensor transmits information to the separation motor and the control valve respectively, and the separation
motor drive the separation screw to rotate in the
positive direction, so that the screw pushes the main box body and the sub box body to separate, thereby preventing the fire from spreading and causing great loss. At the same time, the control valve is opened, the sand in the sand storage box enters the spraying device through the sand feeding
pipe, and finally sprays through the
nozzle to cover the fire and extinguish the fire, so as to ensure that the fireis extinguished in the
sprouting state to the maximum extent.
