The invention discloses a regional protection system for spacecraft fuel filling leakage. The regional protection system comprises a remote control subsystem, and a deluge water spraying subsystem, an accident waste liquid collection subsystem, an accident exhaust subsystem and a gas leakage detection subsystem which are linked with the remote control subsystem, the gas leakage detection subsystem is used for detecting the concentration of poison gas in a fuel filling area in real time, sending an alarm signal to the remote control subsystem when the concentration of the poison gas is detected to exceed the standard, and sending the alarm signal to the remote control subsystem after a fuel leakage accident is confirmed. The remote control subsystem sends starting instructions to the deluge water spraying subsystem, the accident waste liquid collecting subsystem and the accident exhaust subsystem, and all the subsystems are started to protect a fuel adding area. Wherein the deluge water spraying subsystem is used for carrying out spraying protection on a fuel adding area, the accident waste liquid collecting subsystem is used for collecting leaked fuel and waste water generated by spraying of the deluge water spraying subsystem, and the accident exhaust subsystem is used for discharging poison gas in the fuel adding area in time.
本发明公开了一种用于航天器燃料加注泄漏的区域保护系统,包括:远程控制分系统以及与远程控制分系统联动的雨淋喷水分系统、事故废液收集分系统、事故排风分系统和气体泄漏探测分系统;所述气体泄漏探测分系统用于实时探测燃料加注区域内毒气的浓度,当探测到毒气的浓度超标时,向远程控制分系统发出报警信号,确认发生燃料泄漏事故后,远程控制分系统向雨淋喷水分系统、事故废液收集分系统和事故排风分系统发出开启指令,启动各分系统对燃料加注区域进行保护;其中,雨淋喷水分系统用于对燃料加注区域进行喷淋保护,事故废液收集分系统用于收集泄漏的燃料和雨淋喷水分系统喷淋产生的废水,事故排风分系统用于将燃料加注区域中的毒气及时排出。
