DEVICE FOR SELECTIVE COLLECTION OF SOLID SUSPENDED PARTICLES IN AQUATIC MEDIUM Russian patent published in 2021 - IPC G01N1/04 

FIELD: hydrobiology.

SUBSTANCE: group of inventions relates to the field of hydrobiological research and ecological monitoring of the aquatic environment. Disclosed is a device for collecting solid particles in an aquatic environment, which consists of a removable net catcher. The removable mesh catcher is a truncated cone, which is fixed inside a rigid channel frame. The device also includes floats. In this case, the net catcher is a regular truncated cone made of a stretched knotless netting fabric with a constant mesh size in the range of 0.035-1 mm, made of materials of the group: metal, metal alloy, polymer, silk. The net catcher is rigidly fixed in a tensioned between the base frame from the front end and a fixed flange ring from the rear end, to which the collector glass is attached with the possibility of replacing it, while the device also contains two floats spaced apart on the sides, which are attached to the frame frame. Also disclosed is a complex for collecting solid particles in an aqueous medium, containing at least two of these devices.

EFFECT: group of inventions provides an increase in the rigidity and reliability of the structure, the security of the net catcher and, as a consequence, the improvement of its metrological characteristics, the expansion of the functionality and ease of operation of the device.
