  • Publication number: 20240263415
    Abstract: An unpowered-filtering sewage cleaning device includes a sewage discharge mechanism, a water conveyance mechanism, a filtration mechanism, a water guidance mechanism, a water discharge mechanism, a support mechanism, and a transmission mechanism. The transmission mechanism includes a main transmission shaft, a clutch mechanism, and an auxiliary transmission shaft. The main transmission shaft is mounted with the auxiliary transmission shaft through the clutch mechanism. In case of disengagement of the clutch mechanism, the main transmission shaft rotates, while the auxiliary transmission shaft does not rotate. In case of engagement of the clutch mechanism under a pressure, the main transmission shaft drives the auxiliary transmission shaft to rotate coaxially. The water conveyance mechanism, the filtration mechanism, and the water guidance mechanism are mounted with the main transmission shaft. The sewage discharge mechanism is mounted with the auxiliary transmission shaft.
