Tunnel type automatic fireproof plugging device
The invention discloses a tunnel type automatic fireproof plugging device. The tunnel type automatic fireproof plugging device comprises a frame fixed to the inner periphery of a tunnel, a fireproof plugging plate inlaid in the frame, a left fireproof door, a right fireproof door, a flexible fireproof blanket arranged on one side of the left fireproof door and one side of the right fireproof door, and rotating shafts arranged on the left side and the right side of the tunnel correspondingly and fixed to the frame; the rotating shafts are hinged to the left fireproof door and the right fireproof door correspondingly; a left fireproof door upper section and a left fireproof door lower section as well as a right fireproof door upper section and a right fireproof door lower section can be integrally bent with the tunnel circular diameter through connecting shafts correspondingly, a left fireproof door descending plugging plate is arranged at the lower end of the left fireproof door lower section, rotating guide wheels are arranged on the left side and the right side of the left fireproof door descending plugging plate correspondingly, and the guide wheels are embedded in a left fireproof door descending slide rail groove and are arranged in a rolling mode. The tunnel type automatic fireproof plugging device has the beneficial effects that fire alarm is used as a starting signal, the tunnel is closed through the fireproof door, the safety fireproof coefficient and efficiency are improved, the structure is simple, the design cost is low, and installation is more simplified.
本发明公开了一种隧道式自动防火封堵装置，包括固定在隧道内周边的框架、镶衔在框架内防火封堵板、左防火门、右防火门、设置在左防火门和右防火门一侧的柔性防火毯、分别布置于隧道左右两侧且固定在框架上的转轴，转轴分别铰接于左防火门和右防火门；左防火门上段和左防火门下段、右防火门上段和右防火门下段分别通过连接轴可与隧道园径一体弯曲，所述左防火门下段下端布置有左防火门下行封堵板，左防火门下行封堵板左右两侧分别布置转动的导轮，导轮内嵌于左防火门下行滑轨槽内并滚动布置。本发明的有益效果是：本发明以火灾报警为起动信号，采用防火门来封闭隧道，不仅提升安全防火系数和效率，而且结构简单，设计成本较低，安装更加简化。
