Cleaning Device For A Submerged Surface

Patent No. EP4085764 (titled "Cleaning Device For A Submerged Surface") was filed by Aqua Robotics on Jan 22, 2019. The application was issued on Nov 6, 2024.

Patent Summary

A rotatable brush for cleaning submerged nets, such as fish-farming cage nets, comprises a brush core with a rotational axis and multiple bristles. Each bristle features an attachment portion fixed to the core and a free end. Upon rotation, the free end follows a circular circumferential path centered on the rotational axis. The bristle's end portion is characterized by a kink or bend, causing it to form a secant angle ($\alpha$) with the circumferential path, where $\alpha \neq 90^\circ$. This configuration enables gentle, regular in situ cleaning to prevent fouling. In multi-brush devices, pairs of brushes with opposite bristle orientations may be utilized to maintain consistent cleaning efficiency regardless of the device's vertical direction of motion.
