Fire extinguishing system for electric power tunnel pipe gallery

Abstract

The fire extinguishing system for the electric power tunnel pipe gallery comprises the electric power pipe gallery, a partition plate is fixedly connected to the inner side of the electric power pipe gallery, a fire extinguishing foam bottle is fixedly arranged at the position, located on one side of the partition plate, of the bottom of the inner side of the electric power pipe gallery, and an outlet is formed in the top of the fire extinguishing foam bottle and fixedly connected with a guide pipe. The inner top wall of the electric power pipe rack is provided with a slot for mounting a guide pipe, the guide pipe is provided with a plurality of branch pipes, the bottom ends of the branch pipes are provided with nozzles, the inner top wall of the electric power pipe rack is provided with a smoke sensor and a temperature sensor on one side of the nozzles, the branch pipes are internally provided with electromagnetic valves, and the side wall of the partition plate is fixedly provided with a microprocessor. When the corresponding smoke sensors and the temperature sensors transmit signals at the same time, it is indicated that a fire occurs, the microprocessor controls the corresponding electromagnetic valves to be opened, then foam in the corresponding branch pipes is sprayed out through the sprayers, fire extinguishing is conducted nearby, fire extinguishing is conducted in a targeted mode by determining the ignition point, and the fire extinguishing efficiency is improved.
