This invention discloses a smart fire sprinkler system for high-rise buildings, comprising a movable plate with a water tank fixedly connected above it. The water tank has a drainage channel inside, and a ball valve is rotatably connected inside the drainage channel. One end of the ball valve is fixedly connected to a gear, which meshes with a gear ring. When the device's ratchet rotates forward, it drives a sweeping rod to clean the surface of the filter holes, directly intercepting debris and dirt generated in the water tank and pipes due to aging, preventing them from entering the sprinkler rod and clogging the nozzles. Simultaneously, when the ratchet rotates in the reverse direction to drain the water tank, the sweeping rod continues to clean the filter holes, discharging residual dirt along with the drainage, reducing the accumulation of dirt in the water tank and pipes from the source. Compared to traditional sprinkler systems that rely on manual disassembly and cleaning, this automated cleaning mechanism requires no additional manual intervention and can address the problem of dirt generation in the complex layout of high-rise buildings in real time, effectively preventing sprinkler failure due to dirt clogging.
