The invention provides a water spraying system for a drilling floor of a drilling ship, which comprises a seawater control pipeline, an air control pipeline, a deluge valve, a three-way electromagnetic valve, a spray head, a fire monitoring probe, a signal acquisition control box, a signal control device, a control switch, a remote manual release button and a center console, the signal acquisition control box receives fire signals transmitted by the fire monitoring probe and transmits the fire signals to the signal control device directly or through the center console, the signal control device transmits the electric signals to the three-way electromagnetic valve, the deluge valve is controlled to be opened through the three-way electromagnetic valve, and the spraying system is further started to extinguish fire. According to the spraying system provided by the invention, an automatic remote control mode and a manual remote control mode are switched through the control switch, and the spraying system is emergently started on site by opening the emergency release ball valve on the seawater control pipeline, so that the system control requirements under various scenes such as unattended operation and on-site sudden fire are met; the fire can be timely and effectively found and restrained, and the safety performance of the drilling ship is improved.

    本发明提供了一种用于钻井船钻台的水喷淋系统,包括:海水控制管路、空气控制管路、雨淋阀、三通电磁阀、喷头、火灾监测探头、信号采集控制箱、信号控制装置、控制开关、远程手动释放按钮和中控台,信号采集控制箱接收火灾监测探头传递的火情信号,并直接或通过中控台传递给信号控制装置,信号控制装置再将电信号传递给三通电磁阀,通过三通电磁阀控制雨淋阀开启,进一步启动喷淋系统进行灭火。本发明所提供的喷淋系统通过控制开关切换自动和手动远程控制模式,通过打开海水控制管路上的应急释放球阀在现场紧急启动喷淋系统,满足无人值守、现场急火情等各种场景下的系统控制需求,能够及时有效的发现并遏制火情的发生,提升了钻井船的安全性能。
