Outdoor water leaking self-closed fire hydrant
The invention relates to the technical field of safety fire protection and discloses an outdoor water leaking self-closed fire hydrant which comprises an upper shell and a lower shell buried in the earth's surface; the upper shell is connected with the lower shell in a penetrating manner; a hose is mounted at the inner ring of the lower shell; the top of the hose is arc shaped; a support rod is mounted in the hose; a water storing pipe is arranged at the outer ring of the support rod; the outer wall of the support rod and the inner wall of the water storing pipe are mounted in a sleeve joint manner; and a water inlet is formed in the tail end of the water storing pipe. According to the outdoor water leaking self-closed fire hydrant, the hose is arranged, so that the lower shell is changedinto a hard and soft combined type aqueduct from a hard water pipe, and after the lower shell cracks, the hose continues to play a role of flow guiding to reduce the flow velocity of a water source; through arranging an arc shaped pipe and the water storing pipe, after the shell cracks, the arc shaped pipe compresses the water flow in the water storing pipe to enable water to flow into an air sac,so that the air sac is continuously expanded to block the outlet of the hose to further block water flowing.
本发明涉及安全消防技术领域，且公开了一种室外漏水自封闭式消防栓，包括上壳体和埋藏于地表的下壳体，所述上壳体与下壳体贯通连接，所述下壳体的内圈处安装有软管，所述软管的顶部形状呈弧形，所述软管内安装有支撑杆，所述支撑杆的外圈处设置有蓄水管，所述支撑杆的外壁与蓄水管的内壁为套接式安装，且蓄水管的末端开设有进水孔。该室外自封闭式消防栓，通过软管的设置，使得下壳体有硬质水管改变为硬质加软质组合式导水管，使得下壳体破裂后，软管继续充当导流的作用，减小水源的流速，同时通过弧形管与蓄水管的设置，使得壳体破裂后，弧形管压缩蓄水管中的水流，流动至气囊中，使得气囊不断扩大，从而封堵软管的出口，进而堵塞水流的流动。
