Linkage fire extinguishing system
The invention relates to the technical field of fire disasters, in particular to a linkage fire extinguishing system. The system comprises a fire extinguishing device, a floor drain drainage device, a suspended ceiling device and a controller. The floor drain drainage device comprises a drainage pipe and an electromagnetic valve mounted on the drainage pipe. The suspended ceiling device comprises a suspended ceiling opening and an opening and closing mechanism. The fire extinguishing device, the electromagnetic valve and the opening and closing mechanism are all electrically connected with the controller. When the fire extinguishing device extinguishes fire, the controller controls the opening and closing mechanism to be started so as to open the suspended ceiling opening at a suspended ceiling of a protection area and meanwhile controls the electromagnetic valve to be closed so as to close the drainage pipe of the floor drain device of the protection area, so that the whole protection area formed by the suspended ceiling layer and the space below the suspended ceiling is rapidly filled with heptafluoropropane, the fire extinguishing efficiency is improved, after the enclosure structure of the protection area bears overpressure of the internal pressure, the pressure can be relieved through a pressure relief opening formed in a side wall in the suspended ceiling, it can be guaranteed that a heptafluoropropane fire extinguishing agent in the protection area cannot be lost from a floor drain, the fire extinguishing concentration can be accumulated as soon as possible, and the fire extinguishing effect is achieved.
本发明涉及火灾技术领域，尤其是涉及一种联动灭火系统，其包括灭火装置、地漏排水装置、吊顶装置以及控制器；地漏排水装置包括排水管以及安装在排水管上的电磁阀；吊顶装置包括吊顶开口以及开闭机构；灭火装置、电磁阀与开闭机构均与控制器电连接。当灭火装置进行灭火时，控制器控制启动开闭机构以将防护区吊顶处的吊顶开口打开，同时控制关闭电磁阀以关闭防护区的地漏装置的排水管，使得七氟丙烷快速充满吊顶层和吊顶下空间组成的整个防护区，提高灭火效率，也便于当防护区围护结构承受内压超压后，可通过吊顶内的侧墙上设置的泄压口泄压，可保证防护区内的七氟丙烷灭火剂不从地漏流失，能尽快积累到灭火浓度，达到灭火效果。
