Abstract

The utility model relates to a flagpole capable of waving a flag. The upper end of a fixed flagpole is provided with a rotatable flagpole through a bearing. The rotatable flagpole is a steel pipe of which the top end is closed. The inner lower part of the steel pipe is provided with an inverted necking port. The outer wall of the supporting pipe connected to the necking port is matched with the inner circle of the bearing. The inner wall of the steel pipe arranged at the top of the fixed flagpole is matched with the outer circle of the bearing. The inner cavity of the steel pipe is divided into two parts by a baffle plate arranged in the steel pipe of the rotatable flagpole along a shaft line. The lower end of the baffle plate is positioned above the necking port. Passing slots which are parallel mutually are arranged on the steel pipe walls arranged on both sides of the baffle plate. Wind screens are uniformly and orderly distributed on both of the two sides of the baffle plate. The upper and the lower parts of the center line of the parallel passing slots are respectively provided with a rope pulley. A blower fan is arranged in a base arranged on the lower end of the fixed flagpole. Wind is supplied by the blower fan through a wind pipe arranged in the fixed flagpole. The utility model not only can make a flag wave following natural wind, but also can make the flag wave by the generated mechanical wind when natural wind does not exist. The structure is reasonable.

Description

Make the flagpole of flag blowing

Technical field

The utility model belongs to the improvement of hanging the flag flagpole, particularly makes the flagpole of flag blowing.

Background technology

The flagpole of present widely used suspension flag, its structure is that upright truck is equipped with rope sheave, on the movable short flagpole flag is installed, and the top and bottom of movable short flagpole are connecting rope respectively, rope rises flag by rope sheave, and relative positioning is in upright flagpole upper end.Having under the situation of wind, flag in wind, and flag is flown in the wind; Do not having under the situation of wind, flag is sagging naturally, can not represent the elegance of flag.

The utility model content

The purpose of this utility model is to provide a kind of flagpole that makes flag blowing, is not only having under the situation of natural wind, and flag flies in the wind, and is not having under the situation of natural wind, and the mechanical wind of generation still flies in the wind flag, and it is rational in infrastructure, is easy to promote.

The purpose of this utility model is achieved in that a kind of flagpole that makes flag blowing, comprise upright flagpole and the rope sheave of installing in the flagpole upper end, the fixedly flagpole that constitutes by steel pipe, its upper end is installed with rotating flagpole by bearing, rotating flagpole is the steel pipe of top closure, bottom in steel pipe is being provided with the necking down mouth of back taper, its outer wall of the stay pipe that connects on the necking down mouth combines with bearing inner race, fixedly the steel pipe inwall of truck matches with bearing outer ring, the stay pipe that is connected on its top of airduct that is provided with in fixing flagpole and the rotating flagpole necking down mouth movingly, along the dividing plate that is provided with on the axis steel pipe inner chamber is separated into two parts in the rotating flagpole steel pipe, the lower end of dividing plate is positioned at the top of steel pipe back taper necking down mouth, the groove that is parallel to each other is being set on the steel pipe walls of dividing plate both sides, the uniform successively from bottom to top verge board that is being provided with in the both sides of dividing plate, upper and lower at two groove center lines is installed with rope sheave respectively, in the base of fixing flagpole lower end blast fan is installed, blast fan is by the fixing interior air duct blow of flagpole.

The utility model fixedly upper end of flagpole is installed with rotating flagpole by bearing, by rope sheave flag is installed on rotating flagpole.Having under the situation of natural wind, flag waves with the wind.When wind direction changed, rotating flagpole rotated under flying colors drives with the wind, has prevented that when wind direction changed, flag was wrapped in the drawback on the flagpole.When not having natural wind, start blast fan, blast fan is by the air duct blow in the flagpole steel pipe, and mechanical wind enters in the rotating flagpole steel pipe, enters in two inner chambers of rotatable flagpole steel pipe by dividing plate machinery wind.Because the uniform successively from bottom to top verge board that is being provided with in the both sides of dividing plate, the mechanical wind that enters inner chamber is through verge board uniform distribution from bottom to top, the groove that is parallel to each other on the steel pipe walls of dividing plate both sides blows out, make by rope sheave and be installed in flag two sides wind-engaging on the parallel channels center line, fly in the wind.The utility model is having under the situation of natural wind, and flag flies in the wind, and is not having by mechanical wind flag still to be flown in the wind under the situation of natural wind.It is rational in infrastructure, is easy to promote.
