Fire hydrant intelligent lock
The invention discloses a fire hydrant intelligent lock in the technical field of fire-fighting equipment Internet of Things terminals. The fire hydrant intelligent lock comprises a pipeline, whereina lock shell is fixedly arranged on the front wall of the pipeline, a valve rod is arranged in an inner cavity of the pipeline, a ratchet wheel is clamped on the outer wall of the valve rod, the ratchet wheel is positioned in the inner cavity of the lock shell, a first limit switch and a second limit switch are arranged in the inner cavity of the lock shell, the front wall of the lock shell is inthreaded connection with a gear motor through a gear motor fixing block, an output shaft of the gear motor penetrates through the front wall of the lock shell and is provided with an eccentric cam through a C key, a pawl is in pin joint with the inner cavity of the lock shell, the end of the pawl is clamped with the outer wall of the ratchet wheel, the outer wall of the eccentric cam makes contactwith the outer wall of the pawl, an extension spring column is fixedly installed on the front wall of the lock shell, and an extension spring is arranged on the outer wall of the extension spring column. According to the fire hydrant intelligent lock, the situation that a valve cannot be closed when the valve is not closed during locking is avoided, the situation that a fire hydrant or the valvecannot be rapidly started during unlocking faults or fire emergency is avoided, and the environmental adaptability is higher.
本发明公开了消防设备物联网终端技术领域的一种消火栓智能锁，包括管道，管道的前壁固定安装有锁壳，管道的内腔设置有阀杆，阀杆的外壁卡接有棘轮，棘轮位于锁壳的内腔，锁壳的内腔分别设置有第一限位开关和第二限位开关，锁壳的前壁通过减速电机固定块螺接有减速电机，减速电机的输出轴贯穿锁壳的前壁，减速电机的输出轴通过C键安装有偏心凸轮，锁壳的内腔销接有棘爪，棘爪的端部与棘轮的外壁卡接，偏心凸轮的外壁与棘爪的外壁接触，锁壳的前壁固定安装有拉伸弹簧柱，拉伸弹簧柱的外壁设置有拉伸弹簧，本装置避免了关锁时阀门尚未关闭时无法关闭阀门的情况，避免在开锁故障或消防应急时无法快速启用消火栓或阀门，环境适应性更强。
