SYSTEM FOR CREATING A MIST-DROP-LIKE FRONT, A KIT FOR CREATING A MIST-DROP-LIKE FRONT AND PROJECTING IMAGES ON IT UNDER THE SPANS OF BRIDGE STRUCTURES Russian patent published in 2023 - IPC G03B21/608 

FIELD: promotional materials.

SUBSTANCE: means for creating a mist-drop-like front used to demonstrate promotional materials. Kit for creating a mist-droplet front contains a water supply system, a mist-droplet-forming system, a video projection system and a control module. This system includes two three-way electromagnetic hydraulic valves (10). The first outlet of the first valve is connected to the inlet of the mist atomizer (12) via a high pressure pipeline (11). The outlet of the mist atomizer (12) is connected to the first line (13) of the mist-droplet unit. The second outlet of the first valve communicates with the inlet of the second valve via a high pressure pipeline (11). The first outlet of the second valve is connected to the second line. The second outlet of the second valve is connected to the third line (13). In this case, the lines (13) are made in the form of pipes, along which nozzles (14) with outlets of different diameters are mounted at equal distances.

EFFECT: projection of video images onto a mist-drop-like front under spans of bridges in various wind conditions.
