With the constantly development of large space, the fire prevention of large space building is also increasingly important, but the traditional fire extinguishing system can not satisfy the requirements of fire extinguishing of interior large space. An intelligent fire extinguishing system of interior large space that using the single chip microcomputer SPCE061A as the main controller was designed...
The traditional fire extinguishing system can not satisfy the requirements of fire extinguishing of interior large space as its own shortcomings. An auto-targeting fire extinguishing system of interior large space based on the single chip microcomputer control was designed. The fire extinguishing system was driven by two perpendicular stepper motor, and the fire location was detected using flame sensors...
Fire water monitor is one of the main equipment widely used in the fire fighting. A liquamatic fire water monitor with vavle-controlled cylinder device was designed. This fire water monitor head is controlled by a vavle-controlled cylinder device, which is driven by the water pressure and reciprocated by using mechanical feedback device. The hydraulic performance simulation of the liquamatic fire...
Aiming at the requirements of the soft layer in the tunneling constructions, a virtual prototype model of shield cutter head with diameter of 6.34 meters was designed using Pro/E software, and the cutter head, cutter tool and cutter seat were also virtually assembled. Meanwhile, the two typical working conditions of the cutter head model were analyzed in the environment of ANSYS. The structural parameters...
