CN2240010Y - Automatic fluttering flagpole - Google Patents

Abstract

The utility model relates to an automatic fluttering flagpole, which is composed of a base, a round rod, and a top ball. The utility model is characterized in that the inner part of the base is provided with a small-sized air compressor and a control device; the round rod is a hollow tube, and the upper part of the round rod is provided with two rows of air nozzles; the inner part of the top ball is provided with a wind force detector; under a windless condition, air with stated air pressure can be automatically conveyed to the nozzles, airflow is spouted toward both sides of the flag, and therefore, the flag is spread to flutter. The utility model has the advantages that when a flag is hoisted, regardless of wind or windlessness, a flag can be spread; therefore, the ceremony of a flag hoist can be grander, and the vigour of a flag hoist is increased.

Description

Automatic Flagpole with jet pipe for flag waving

The utility model belongs to the flagpole field.

The general form of structure of flag rising pole commonly used is at present fixed a garden bar for a pedestal is arranged on pedestal, often there is a garden ball in masthead portion in garden, mixes the anchoring of a cover hand or automatic lifting flag.During flagraising, flag is raised to the top of garden bar by manual or electric device, below the ball of garden.When wind was arranged, the flag face was waved by the wind exhibition, and when calm, the flag face can hang the top at flagpole from above, seems listless, lifeless.

The purpose of this utility model is exactly the weak point that will remedy above-mentioned flagpole, invent a kind of flagpole that can when calm, automatically flag be launched, make flagraising ceremony more be added with imposing manner, solemn respectful order, no matter wind or calm is arranged when hoisting a flag, can both launch flag, allow it wave constantly, give and inspire and strength, strengthen the solemn effect and the effect of flagraising ceremony.

Design philosophy of the present utility model is by a small-sized air compressor machine and control device, when calm, the air of certain air pressure is delivered to the top of tubulose garden bar, by two row's puff prots of bar top, garden and the same height of flag face, launch flag after making air-flow spray to the flag two sides, it is waved.It is achieved through the following technical solutions.Automatically Flagpole with jet pipe for flag waving is made up of pedestal (1), garden bar (2), heading (3), a small-sized air compressor (4) and air pipe line (5) is housed, control device (6) and circuit (7) in pedestal (1); The garden bar is a hollow tubular structures, at garden bar the first half left and right symmetrically two comb shape puff prots (8) is housed; Garden masthead end is equipped with heading (3), and heading a ball is hull shape, and is divided into upper and lower two parts, lower house and garden bar link together, and wind-force tester (9) is housed in the lower house, leave the space between upper shell and the lower house, upper shell is associated on the lower house by connecting band, sees accompanying drawing 1.

In two row's puff prots, the odd numbers puff prot of A face is to low-angle of axial line inclination of garden bar, as 15 degree about bar top, garden.Also to low-angle of axial line inclination of garden bar, remaining puff prot parallels with axial line the even numbers puff prot of B face.And the position of the puff prot of smallest end should be lower than the lower end of flag face, and what of puff prot are inversely proportional to the size of spout.

The wind-force tester of dress is made up of weathercock (11) and generator (12) in heading (3) lower house.

At garden bar first half inner chamber, under nethermost spout, be provided with a seal diaphragm (13).

Effect of the present utility model is to have under wind or the calm situation, all can make flag launch to wave, and strengthens the solemn effect and the effect of flagraising ceremony greatly, is particluarly suitable for using in great international conference, the national flag flagraising ceremony.Its control device is simple, reliable.

Accompanying drawing 1 is the composition structure chart of automatic Flagpole with jet pipe for flag waving.

Accompanying drawing 2 is control circuit figure of automatic Flagpole with jet pipe for flag waving.Wherein: 1-pedestal, 2-garden bar, 3-heading, 4-small-sized air compressor, 5-air pipe line, 6-control device, 7-lead, 8-tubulose puff prot, 9-wind-force tester, 10-connecting band, 11-weathercock, 12-generator, 13-seal diaphragm, I-rectifier, II-A.C. contactor.

Be an embodiment of the present utility model below, be described with reference to the accompanying drawings details of the present utility model.

IC555 among the accompanying drawing 2 control circuit figure is a time base circuit, and 1 end is an earth terminal, and 2 ends are trigger ends, and 3 ends are output, and 4 ends are the forced resetting end, and 5 ends are by capacity earth, and 8 ends are power end, connect+the 12V power supply.

When natural wind-force is lower than 4 grades, control device starts to work automatically, when 2 terminal potentials be lower than 8 terminal voltages 1/3 the time, 3 ends become high potential, relay is engaged, drive the A.C. contactor adhesive, make small-sized air compressor work,, to each puff prot (8) flag is launched to wave by pipeline (5) air-supply.

When natural wind surpasses 4 grades, the weathercock of wind-force tester rotates to be accelerated, the generated energy of the generator of its lower end is increased sharply, bridge rectifier work, and make Zener diode " puncture ", electric current is by current-limiting resistance and diode and ground formation path, at this moment produce a junction voltage in diode, this junction voltage just as the trigger voltage of 4 ends, just can trigger as long as this voltage is lower than 0.3V, it makes 3 end vanishing level again, relay can not be worked this moment, and the contact disconnects, and A.C. contactor just is disconnected, air compressor machine is quit work, and at this moment flag flutters by natural wind fully.
