具体实施方式
为使本发明实施例的目的、 技术方案和优点更加清楚, 下面将结合本 发明实施例中的附图, 对本发明实施例中的技术方案进行清楚、 完整地描 述, 显然, 所描述的实施例是本发明一部分实施例, 而不是全部的实施例。 基于本发明中的实施例, 本领域普通技术人员在没有作出创造性劳动前提 下所获得的所有其他实施例, 都属于本发明保护的范围。 如图 1、 2和 3所示, 本发明机车自动灭火装置的实施例, 包括控制 系统 8、 火灾监控系统、 报警系统和灭火系统, 所述火灾监控系统、 所述 报警系统和所述灭火系统分别与所述控制系统 8电连接, 所述火灾监控系 统和所述灭火系统设置于火灾监测区, 即牽引机车及发电车易着火的部位 和配电拒内,所述报警系统及所述控制系统 8均设置于机车操作室,另夕卜, 报警系统还同时设置于火灾监测区。
进一步的, 火灾监控系统包括至少一个感烟探测器 7和至少一个感温 探测器 6 , 感烟探测器 7和感温探测器 6分别与控制系统 8电连接, 感烟 探测器 7和感温探测器 6的个数依据火灾监控区的大小来具体确定。 感烟 探测器 7和感温探测器 6安装在牽引机车及发电车易着火的部位和配电拒 内。 在进行火灾监测时, 只有感烟探测器 7和感温探测器 6同时触发, 向 控制系统 8发送相应信号时, 控制系统 8才控制灭火系统实施灭火操作, 即开始喷射灭火介质进行灭火。 也就是说, 仅感烟探测器 7或感温探测器 6单独触发时, 控制系统 8不打开灭火系统, 此时灭火系统不进行灭火操 作。 当然, 也可以釆用与控制系统电连接的紫外火焰探测器, 来代替感烟 探测器 7和感温探测器 6 , 釆用紫外火焰探测器时, 只要其触发, 便说明 已发生火灾, 此时, 控制系统 8控制灭火系统实施灭火操作。
为了做到在火灾发生时, 能够及时的通知车辆机组人员, 以便其做出 相应的应急措施, 来降低火灾所带来的伤害及损失。 而将报警系统设置在 机车操作室, 报警系统可以釆用声 /光报警器 9。 当火灾发生时, 控制系统
8控制声 /光报警器 9工作,声 /光报警器 9发出报警声同时还进行强光闪烁, 以告知车辆机组人员列车内出现了火灾。
本实施例中的灭火系统包括一个灭火介质储存罐 1 , 灭火介质储存罐 1 内储存七氟丙烷气体。 在灭火介质储存罐 1的灭火介质出口上密封连接 一个容器阀 2 , 容器阀 2具有主气路入口、 主气路出口、 控制气出口和控 制气入口, 所述主气路入口与所述灭火介质储存罐的灭火介质出口连接, 所述主气路出口连接灭火介质管路系统 4 , 所述控制气出口上连接电磁阀 3 , 所述电磁阀 3的气体出口上连接单向阀 1 1 , 所述单向阀 1 1的气体出口 与所述控制气入口相连接,所述灭火介质管路系统 4中连接有灭火喷头 5 , 灭火喷头 5设置在牽引机车及发电车易着火的部位和配电拒内, 以便进行 有针对性的灭火。 在进行灭火时, 电磁阀 3首先打开, 灭火介质储存罐 1 内的气体先经电磁阀 3进入单向阀 1 1 , 再由单向阀进入到容器阀, 来使得 容器阀导通, 以便灭火介质储存罐 1 内的气体经主气路出口进入到灭火介 质管路系统 4内。 这里, 电磁阀 3与单向阀 1 1组成了控制容器阀 2通断 的开关部件。由于容器阀 2属于现有结构,这里不对其具体结构进行赘述。
其中, 灭火介质管路系统 4与主气路出口连接的一段管路为高压软管
13 , 在高压软管 13的管接头 14上固定安装有压力传感器 12 , 压力传感器 12与控制系统 8电连接以反馈灭火介质是否喷放, 若压力传感器 12测得 高压软管 13 内有压力则说明灭火介质已成功喷放, 否则喷放失败。 在喷 放失败时, 需要对电磁阀 3进行手动开启, 以使灭火介质顺利的进入到灭 火介质管路系统 4内来进行灭火。
为了便于观察灭火介质储存罐 1内的压力,在容器阀 2上固定安装了 压力表 10 , 压力表 10与主气路入口连通。
本发明的机车自动灭火装置在控制灭火系统打开的方式上具有自动、 手动和机械应急操作三种方式。
该机车自动灭火装置在启动后的原始状态为手动状态, 此时, 按下控 制控制系统面板上的自动 /手动转换按钮 3S以上, 便转化为自动状态。 在 特殊情况下, 自动启动和手动启动均失效时, 可以釆用机械应急操作的方 式来开启灭火系统。
自动状态: 在火灾发生时, 感烟探测器 7和感温探测器 6同时触发, 并向控制系统 8发送相应的监测信号, 控制系统 8接收到上述监测信号后 进入延时 (延时时长可根据需要设定) 阶段, 在延时阶段声 /光报警器 9 工作, 发出警示信号。 在延时时长结束后, 控制系统 8启动灭火系统进行 灭火操作。 若在延时阶段, 工作人员发现此火灾信号为误报, 或火灾情况 无需启动机车自动灭火装置时, 可以按动控制系统 8上的复位按钮来中断 灭火程序, 此时, 感烟探测器 7和感温探测器 6再次进入监测状态。
在火灾发生时, 若控制系统 8未成功开启灭火系统, 则此时可以人为 按下控制系统面板上的紧急启动按钮,进行紧急启动灭火,进行此操作时, 不经过延时程序。
手动状态: 在发生火灾时, 感烟探测器 7和感温探测器 6同时触发, 并向控制系统 8发送相应的监测信号, 控制系统 8接收到上述监测信号后 开启声 /光报警器 9 , 此时, 必须由人为按下控制系统 8面板上的紧急启动 按钮, 才能启动灭火系统进行灭火作业。
机械应急操作: 在自动状态和手动状态均失效的情况下, 工作人员必 须到灭火介质储存罐 1处, 拔出电磁阀 3的保险销, 并拉出紧急启动环来 紧急启动灭火系统进行灭火操作。
最后应说明的是: 以上实施例仅用以说明本发明的技术方案, 而非对 其限制; 尽管参照前述实施例对本发明进行了详细的说明, 本领域的普通 技术人员应当理解: 其依然可以对前述各实施例所记载的技术方案进行修 改, 或者对其中部分技术特征进行等同替换; 而这些修改或者替换, 并不 使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
