Double-disc algae cleaning device

A double-disc algae cleaning device is provided with a sealing cover, two cleaning discs and an algae suction head. The two cleaning discs rotate towards the middle; the algae suction head is arranged on the output side of the two cleaning discs rotating towards the middle, and the bottom corresponds to the bottoms of the cleaning discs; the algae suction head is communicated with a negative pressure source; the rotating algae suction head not only crushes algae on the slope surface of the protective embankment, but also drives the crushed algae to rotate; the algae are driven to the middle position of the two cleaning discs, interfere with each other, do not rotate along with the cleaning discs, are influenced by centrifugal force to reach the hopper opening position of the algae suction head, are sucked by negative pressure of the negative pressure source to enter the algae suction pipeline and leave the cleaning device; compared with an existing algae cleaning device, the difficulty of algae absorption of
