(3) summary of the invention

The purpose of this utility model provides a kind of no matter when wind is arranged still is calm, also regardless of wind direction, and the full-automatic universal flagraising device that flag is unfolded wave at all processes of whole flagraising.The technical solution adopted in the utility model is: full-automatic universal flagraising device comprises flagpole, conductor rope and pole socket, it is characterized in that there is cavity flagpole inside, and there is blast fan at the pole socket place, and the air outlet of blast fan is communicated with an air sub-cylinder; The cavity of flagpole is divided into multistage, and every section all has a plurality of exhaust vents to arrange uniformly in the same side of flagpole from top to bottom, and every section cavity all passes through a pipeline and is communicated with the air sub-cylinder, and an electromagnetic valve is all arranged on each pipeline; Pole socket has bearing.

During flagraising, the whole flagraising time is divided into several sections, starts blast fan, and each electromagnetic valve is opened from the bottom to top successively by delay control circuit, promptly when flag rose to hypomere, the electromagnetic valve of hypomere cavity was opened, and the wind of row's exhaust vent of flagpole hypomere cavity can blow flag flat; When flag rose to second section, second electromagnetic valve opened, and the wind of row's exhaust vent of this section cavity blows flag flat; Flag rises always like this, each cavity air-supply successively from the bottom to top in the flagpole, and when flag rose to the top section, a top section electromagnetic valve was opened, and the wind of top section cavity exhaust vent blows flag flat, and after this, a top section electromagnetic valve is often opened, and makes that flag is high all the time to wave.The utility model makes flag can both launch to wave in the overall process of hoisting a flag by air zoning.When outdoor flagraising, also can cooperate the power of natural wind, regulate the rotating speed of blower fan.Because pole socket has bearing, the flag of lift-off can be followed the natural wind wind direction automatically.Like this, regardless of the wind direction wind-force of natural wind, can both reach best flagraising effect.
