FIELD: construction.SUBSTANCE: flagpole with a forcedly streaming flag, comprising a flagpole proper with a device for flag support in its upper part, besides, the flagpole is made hollow, in its upper part there is at least one hole for supply of compressed air in direction of the flag, a compressor, a mechanism of flag hoisting and a base. Inside the hollow flagpole under the pressure of the compressor arranged in the base, air moves with subsequent discharge via flagpole openings to the flag. In the upper part of the flagpole there is an air flow splitter representing a cylindrical structure, inside of which there is a system of parallel tubes, every tube at the outlet has the specified direction relative to its outlet hole, the splitter base is installed at the angle to the main flow of air and has cross-like partitions relative to the central tube and a protective membrane. There is a sling rope designed for lifting and lowering of the flag, for this purpose a driving reversible electric motor is used, interacting via a geared drive with a lower roller. The electric motor may be put in service both manually and from a signal coming from a timer, and its disconnection may take place due to actuation of end switches. Rollers are arranged on the upper and lower parts of the flagpole so that the flag is arranged relative to output holes or nozzles only by one side of the sling rope, the other sling is at the distance from it equal to the roller diameter.EFFECT: improved reliability and simplified maintenance of a flagpole.4 cl, 8 dwg |
