DEVICE FOR CLEANING WATER BODIES FROM BLUE-GREEN ALGAE Russian patent published in 2015 - IPC E02B15/04 A01D44/00 

FIELD: transport.

SUBSTANCE: device is mounted on a floating craft provided with a winch, a boom and a system of ropes. Longitudinal tie-rods are fixed by means of hinges on one side on the frame of the device, and a rectangle-shaped framework is installed on their other side. The framework with a large-cell mesh with a concave surface is installed with a possibility of changing the position relative to the water body surface. In the upper part of the framework there fixed is a mesh with cells of smaller dimensions, and in the lower part there fixed is a knife throughout the framework width. The boom with a roller on the end is fixed in the middle part of the frame with a possibility of changing an inclination angle. A rope attaching the mesh framework to the two-drum winch is hitched over the roller. The drums are connected to each other with a safety clutch. The direction of synchronous rotation of the drums is provided with a reverser. On one drum the rope is located in an upward direction, and on the other - vice versa.

EFFECT: improving the cleaning efficiency of water bodies from blue-green algae.
