A bus fire extinguishing system

Abstract

The invention provides a bus fire extinguishing system. The bus fire extinguishing system comprises a bus body, wherein a driving seat is arranged on the front side of the bus body, and side seats back to the inner side wall is arranged in the middle area of a bus; a low-pressure liquid storage tank used for storing a fire-fighting liquid is arranged at the bottom parts of the seats; a liquid outlet of the low-pressure liquid storage tank is connected to an upper pipeline system and a lower pipeline system through a fire-fighting liquid outlet pipe, wherein the upper pipeline system comprisesa top pipeline arranged at the top part of the bus body, and multiple rotary sprayers used for extinguishing fire are arranged on the top pipeline; the lower pipeline system comprises a lower pipelinearranged at the bottom region of the side wall of the bus body, and multiple straight spray heads used for extinguishing the fire are arranged on the lower pipeline; a control valve is arranged on the fire-fighting liquid outlet pipe; and a control hand brake for controlling the valve is arranged on the inner side wall, located on the driving seat side, of the bus body. The fire extinguishing system has the advantages that a fire extinguishing agent is large in injection dosage, the fire extinguishing effect is good, and the whole bus fire extinguishing system is free of dead corners.
