Description

The invention relates to a flagpole on which a flag is fixed, forcibly fluttering regardless of weather and atmospheric conditions and location.

Flagstaffs are known on which flags are fixed - state or company - with emblems and logos, see, for example, US patents Nos. 3798816, 5450811 (1, 2).

The closest technical solution to the claimed one is US Pat. No. 3,997,993, which is a flagpole with a waving flag, containing a flagpole with a device for supporting the flag in its upper part, the flagpole made hollow, at least one hole for compressed air in the direction of the flag, there is a source of compressed air, a flag raising mechanism and a base (3).

However, analogues, including the prototype, have a limitation on the mode of operation, do not perform additional important functions.

The objective of the present invention is the possibility of the functioning of the flagpole in both automatic and manual modes, and the technical solution is to increase reliability and simplify maintenance of the flagpole. Thus, the design can be complicated or simplified depending on the functional need.

The flagpole is illustrated in the figures.

The proposed design of the flagpole 1 (figure 1, 2) allows you to raise it with a flag or pennant constantly flutter it even in the complete absence of wind. You can either enter or remove functional blocks or elements from it, as each of them can perform its function autonomously and not affect the operation of other blocks or elements.

The flagpole is made in the form of a hollow pipe, the optimal form of execution is a telescopic structure (Fig. 1, 2) or in the form of a hollow straight or shaped pipe 1 (Fig. 2). The design consists of several cylindrical pipes of different diameters 1 (figures 1, 3). The pipes enter one another as their diameter decreases and are fixed relative to each other by bolts 36 (Fig. 3). The height of the flagpole is determined by the calculation of its stability, depends on the number of component pipe links in the ratio of weight and height to weight and the size of its base. So, a flagpole with a height of 7-12 m can consist of two to three links (the length of one link is 2.5-3 m with an inner diameter of the lower link of 20 cm or more).

In the upper part of the flagpole at the location of the flag 3 (Fig. 1, 2) there are several vertical holes with a thread 4 (Fig. 1, 2, 5). On the thread of these holes are screwed nozzles 5, 6, designed to supply air from the compressor to the flag (figure 3, 6). The nozzles may differ from each other in the direction of the outlet (pos. 8 of Fig. 5,6), which changes the direction of air supply to the flag at an angle α (pos. 8 of Fig. 6), improving the dynamics of blowing the flag. The direction of the nozzle outlet relative to the flag can be adjusted by turning the nozzle on its thread 7 (Fig. 5). Nozzles can be located vertically in several versions (Fig.6): sequentially - pos.8, parallel - pos.9, snake - pos.10, in a checkerboard pattern - pos.11.

When preserving the flagpole to prevent pollution and moisture on the nozzles are plugs made of elastic rubber 12 (figure 5). In the upper part inside the flagpole, a profile splitter 13 (Fig. 5) is installed, designed to reduce the turbulence of the air flow 14 (Fig. 5) from the compressor 15 (Fig. 2, 14) to the nozzles 5, 6 (Fig. 5). The profile pipe-divider can consist of several tubular sections located parallel to each other, for separation of the air flow into smaller ones, which makes the air flow more stable and laminar. The profile pipe also isolates the electromechanical part of the control system 16 (Fig. 5) from the undesirable effects of compressed air coming from the compressor. In the lower part of the flagpole case there are windows 17 (FIGS. 1, 14), necessary for the compressor to take in the outside air. Above the windows 17 on the flagpole case, there are windows 18 (FIGS. 1, 14) designed to exhaust air cooling the case during its operation. Windows 17, 18 (Fig. 14) are located at such an angle to the vertical axis of the casing so that during precipitation the water does not enter the casing. The windows are closed with grids 19 to prevent foreign objects from entering the internal cavity of the flagpole.

For maintenance of the units are technological hatches 2 (figure 1, 2, 14). A protective skirt 22 (FIGS. 1, 2, 14) is attached to the flagpole at its base along the outer perimeter with screws 41 (FIGS. 1, 14), which serves to shield the elements of the rotation platform from the fixed base.

The cable designed for raising and lowering the flag has the shape of a closed ring 20 (Figs. 1, 3) passing through two guide rollers 21. The rollers are located on the upper and lower parts of the flagpole 21 (Fig. 3). If the flagpole has a telescopic structure 1 (Fig. 1), it is necessary to provide for the possibility of moving the upper roller in a horizontal plane relative to the axis of rotation 23 (Fig. 1). You can initially set it in such a way with respect to the lower roller, in order to avoid friction of the cable against the flagpole, when the rollers are in the same plane, the maximum cable tension is possible, which improves the work from the point of view of the effect of the air leaving the nozzles on the flag. The rollers are mounted on the flagpole so that the flag is located in relation to the nozzles on only one sling 24 (Fig.3, 7). The other part of the sling 25 (figure 3) is located at a distance equal to the diameter of the roller 25 (figure 3). Thus, this sling does not interfere with the air flow coming from the nozzles on the flag.

To raise the flag, the cable is activated both manually and in semi-automatic mode.

To raise the flag in semi-automatic mode, half of the flagpole cable should be made in the form of a chain 26 (figure 2, 4). The flag raising mechanism is driven by the mass of the load. The load, having the shape of a cylinder 27 (figure 2, 4), at the initial stage of operation is located in the upper part of the flagpole 27. The lower part of the line on which the load is located has the shape of a chain 26 (figure 4) and the lower part passes through the lower profiled under this chain, the roller 28 (figure 2, 4). The chain length must be such that the chain is always engaged with the lower profiled roller, regardless of the position of the load. This ensures the operability of the flag raising mechanism due to the force of the weight of the load acting on this roller. The upper roller 21 (figure 2, 4), through which the cable passes without chain elements, may have a standard shape.

In the lower part of the flagpole installed mechanical stop 29 (Fig.2, 4), when the load moves down. The limiter has an annular shape with a flange for attaching it to the flagpole. The chain-shaped sling freely passes through the limiter ring, but it is an obstacle for the movement of the load down.

The flag raising mechanism 30 (FIGS. 2, 4) is located in the box of the control unit. On the panel box 31 (figure 4) made controls that control the speed of raising the flag. In the box of the control unit there are also other functional elements, which include a mechanical switch to change the speed of raising the flag. A mechanical switch may be structurally similar to a bicycle switch. It also has a slider cable tension compensator, which allows you to keep the slings in the most stretched state after switching - changing the speed of raising the flag.

Alternatively, when manually descending, the mechanical flag raising device is replaced by an electric one. Raising and lowering the flag is carried out from a reversing low-speed electric motor through a gearbox. When the electric motor is turned on at extreme points from the limit switches, it stops and, through the electromagnetic coupling, fixes the sling.

An elastic U-shaped frame 32 (Fig. 7) is sewn inside the flag along the edge adjacent to the nozzles, which makes the edge of the flag stiff, which significantly improves the dynamics of blowing the flag with air.

The flag is attached to the sling with mechanical clips 33 (1, 2, 7) located between the nozzles of the flagpole. On the flagpole there is a cable clamp 34 (Figs. 1-4) in the form of a spring clip, if the design provides only manual manipulation of raising and lowering the flag (Fig. 3).

At the top of the flagpole is the control system, closed with a decorative sphere-cap 35 (Figs. 1, 2, 8). The internal cavity of the decorative sphere freely communicates with the atmosphere, which is necessary for the operation of the weather vane 36 and the anerubometer 37, as well as the air humidity meter 38 (Fig. 8). In the design of the sphere, it may be possible to replace the mechanical systems of the weather vane and anerubometer with more advanced systems of touch sensors for air speed, direction and humidity. The shape of a sphere (ball) repeatedly dissected in the horizontal plane is held by stiffeners 39. The decorative sphere, as the highest point of the flagpole, has ground 40 (Fig. 8).

Mounting basket

The fastening basket 42 of the flagpole (Figs. 9, 14) is one of the intermediate power links connecting the flagpole to its base. The flagpole 43 is attached to the basket with bolts 44 (Fig. 14). The basket is a cylindrical structure in which there are vertical racks 45 that form the windows 46. The racks are connected in a horizontal plane at three levels. The upper level forms a ring 47. The middle level forms a ring-shaped structure 48 connected to its center via spokes 49. The number of spokes corresponds to the number of uprights, because they are the power link and are connected in the central part. The power elements of the middle spoke wheel in the cross section B, B1 are ellipsoidal in shape 50. Such an aerodynamic form of “flow” is given to the elements to reduce the resistance to air flow passing through the mounting basket. In the central part of the wheel 48 (Fig.9) there is a round groove 51 with a thread for mounting it with an axis.

On the uprights above the middle wheel of the inner part of the basket there are flanges 52 for mounting the compressor 15 on them (Fig. 14). The lower level is a solid disk 53, connected along its perimeter with the uprights. In the center there is a hole 54 for the axis of rotation, as well as a hole 55 and a groove for driving an electric motor.

Between the compressor casing and the basket, as well as between the casing of the basket and the electric motor, rubber bandages 56 are installed (Fig. 14), which have a double function: they serve to reduce the transmission of vibration to the flagpole body during operation of the units and provide electrical insulation between the units and the basket. This design allows free air to be taken by the compressor from the outside through the windows of the flagpole 17 (FIGS. 1, 14) and the space between the racks of the basket — the windows of the basket 46.

The fastening basket together with the flagpole and the axis is mounted on the rotation platform 59 (Fig. 14), while it is a hard link between the flagpole, the axis and the rotation platform. This is due to the screw connection 44 of the flagpole with the mounting basket 42 (Fig. 14) through flanges with a rotation platform and through a threaded connection to the axis. A feature of this model of the mounting basket is that all the main units on which the operation of the entire flagpole design depends are located in its body, which makes the model more convenient to use.

Axis of rotation

The axis of rotation 57 (Fig.10, 14) serves as a power link through the basket with the flagpole and its base. In the middle part of the mounting basket through the thread 58 (figure 10), the axis is attached to the mounting basket 51 (figure 9). Thus, the flagpole, the mounting basket, the rotation platform and the axis are structurally rigidly interconnected structural elements.

The axis 57 extends vertically through the mounting basket, the rotation platform 59 (Fig. 14), the bearing of the base plate 85 (Fig. 14) and the cylinder bearing of the base 96 (Fig. 14). The axis of rotation is fixed from possible movements in the horizontal plane due to its axial bearings. Due to the bearings 85 of the base plate and the bearing of the base cylinder 96 (Fig. 14), rotation in the horizontal plane of the axis, the mounting basket with the flagpole and the rotation platform in any direction without restrictions is provided. In the internal cavity of the axis there is a vertical channel 62 (FIGS. 10, 14), along which an electrically conductive cable passes, connecting the power supply to the consumers of the flagpole.

In the upper part of the axis there is a plug connector 63, in the middle part of the axis in the radial grooves 64 there are connection rings, through which electrical connection between the various flagpole systems is provided when the axis is rotated to any angles with the contacts 65 of the plug connector pressed to them through springs. At the bottom of the internal vertical channel of the axis there is a tap 66, designed to remove condensate.

Rotation platform

The rotation platform 59 (Fig.11, 14), is designed to install flagpole systems on it. It can rotate at any angle and in any direction or make rotational movements relative to its base. The rotation of the platform occurs during operation of the electric motor 67 (Fig. 14), which, through the gear drive 68 passing through the hole 76 in the rotation platform, creates a torque from the interaction with the inner gear 90 (Figs. 12, 14) of the base plate. The rotation platform is a ring-shaped structure, in the middle part it is hollow 77.

In the upper part there are several holes with a thread 70, on which flanges 71 are mounted to fix it through bolts to the flagpole. In the upper part there is also a hole with a nozzle for the grease fitting 72. This hole through the inner channel 73 is connected with a radial groove 74, which is designed to move the upper part of the bearings 80 of the base plate (Fig. 12). To improve the conditions of movement of the rolling bearings, lubricant oil through the lubricator 72 and its channel 73 is fed into the radial groove 74 of the rotation platform 59 (Fig. 11).

Flagpole base. Base plate

The base of the flagpole consists of two main elements - the base plate 78 (Fig. 12, 14) and the base cylinder 94 (Fig. 13, 14).

The base plate accepts the entire vertical load of the flagpole through bearings 80 located in its upper part, which are equidistant from each other along the perimeter of the plate (their number is at least three and varies depending on the load on them). Each bearing is mounted in a plate in a socket 81, in which it fixes its axis from horizontal movements. The inner race of bearings against horizontal movements is fixed on both sides by washers 82. At the bottom of each seat there is a drain channel 83 to remove condensate and excess oil. The bearings are lubricated through the channel 73 (11), connecting the upper part of the platform of rotation with its radial groove under the bearings 80 of the base plate. The lower part of the bearings in the seat has a clearance of 84 with the base plate and does not come into contact with it. In the central part of the base plate, an axial bearing 85 is located below. With its outer cage, it is fixed with the base plate, and the inner cage is fixed with the axis of rotation. Under the bearing in the groove of the plate is a washer 86 (Fig. 12), which has openings 87 for removing condensate and excess oil. The bearing is lubricated through channel 88 from the top of the base plate. The axial bearing of the base plate simultaneously provides the stiffness of the flagpole against horizontal displacements and the free rotation of the axis relative to the plate itself and the base cylinder 94 (Fig. 14).

Along the entire inner perimeter of the base plate 89 (Fig. 12), a gear transmission 90 (Fig. 14) is located in its radial groove, which is designed to transmit torque through the gears of the drive from the operation of the motor 67 (Fig. 14). In this case, the torque is transmitted to the entire flagpole system installed on the rotation platform. The radial groove has the size necessary to pass along the radius of the gears of the drive motor 68. In the radial groove there are through holes 91 (Fig. 14) for drainage of its cavity 89 (Fig. 12). In the base plate there is also a channel 92 for wiring to the plug connector 65 (figure 10). The base plate itself is bolted through its grooves 93 to the upper part of the base cylinder 94 (Fig. 13).

Flagpole base. Base cylinder

Together with the base plate, the base cylinder 94 (FIGS. 13, 14) is part of the structure for fixing the flagpole in a vertical plane.

The base cylinder consists of a hollow cylinder in which a sleeve with a flange 95 is installed. A rolling bearing 96 is mounted on the flange, which is fixed with its outer cage to the base cylinder, and the inner cage to the axis of the flagpole. Lubrication of the bearing is ensured by the supply of lubricant to the axial bearing 85 of the base plate. There is a service door 97 in the base cylinder for maintenance. At the bottom of the cylinder is a spring ground compensator 98, which is designed to provide reliable grounding 99 of the flagpole and which consists of a core with a compensation spring 100. The core under the action of a compressed spring ensures reliable contact of the axis of the flagpole with grounding. The spring with the lower part through the flat washer 101 rests on the annular liner 102, which, like the core, have drainage channels 103, 104 common to the entire base cylinder.

In the upper flat part of the base cylinder, perforated holes 93 are provided for fastening the base plate to the base cylinder. Holes 106 are also located around the perimeter for fastening through the bolts of the base cylinder to the concrete base.

In the upper part of the base cylinder there is an opening 107 for drainage of the cavity of the toothed radial groove 91 (Fig. 14) of the base plate and an opening 108 for drainage of the rolling bearings 80 (Fig. 14) of the base plate 78 (Fig. 12, 14). The hole 109 is intended for wiring from the source to the plug connector of the axis (Fig.13, 14).

Flagpole tracking and control systems

The tracking system is located in the upper part of the flagpole and is closed by a decorative sphere 35 (Figs. 1, 8), which creates reliable mechanical protection and at the same time provides free communication with the atmosphere of the instruments inside it. The sphere is electrically isolated from the flagpole and has an individual ground wire 40 to avoid damage from static electricity or lightning.

The following devices are included in the tracking system: weather vane 36, anerubometer 37, air humidity sensor 38. The weather vane is designed to determine the direction of air movement and plays an important role in the operation of the flagpole. It practically should be included in the work constantly, unlike other units and systems. The work of the weather vane consists in the fact that when it rotates about its vertical axis, when the direction of the wind moves, it transmits an electrical signal-command through the servo unit 110 to the control unit 111 of the electric drive 67. The design of the wind vane has a mechanical or electric damping system that slows down the flow of the control signal during sudden movements of the wind vane. Upon receipt of a command from the control unit 111, the electric actuator 67 unfolds the flagpole so that its nozzles 5, 6 (Fig. 5) repeat the direction of the weather vane, which does not allow the flag to “overflow”, because the direction of the nozzles and the direction of air movement are combined. If necessary, the vane block can be turned off by de-energizing it.

The anerubometer 37 is aligned with the weather vane. He, depending on the measured air velocity in automatic mode, turns on or off the compressor 15 (Fig.2, 14). This depends on the speed set on the dial of the compressor control unit 113. In the manual compressor control mode, the signal from the anerubometer is turned off.

The humidity sensor 38 is located in the decorative sphere 35 at the top of the flagpole. Depending on the air humidity controller located in the servo unit of the humidity sensor 114, a signal is sent to the control unit of the compressor 113. In the automatic operation of the compressor, the air humidity sensor turns on or off the heating system of the air coming from compressor 15. The signal from the humidity sensor can be turned off and produce air heating in manual mode. Alternatively, the design of the tracking system can be made of sensory or other types of electronic sensors, which depends on economic feasibility and the specific design, operating conditions and technical requirements for the flagpole.

The principle of turning on and off the compressor and the drive motor are similar.

Compressor

One of the main structural elements is the compressor 15 (figure 2, 14). The compressor supplies compressed air to the internal cavity of the flagpole. Passing through the cavity, the air exits through the outlet openings 4, 7 and nozzles 5, 6 (Fig. 5), acting on the flag. The type and power of the compressor are selected depending on the size of the flagpole and the flag itself. The compressor can be switched on automatically or manually. When you turn on the compressor in manual mode, it works forcibly, regardless of the signals of the control system of block 112 (Fig. 8). In automatic mode, the compressor turns on and off by a signal from the control system associated with the anerubometer. The compressor may have an air heating system, which is included in the operation both manually and automatically from the control signal of block 114.

Turning on the air heating system in manual mode is done for preventive purposes. Heated air is needed to dry the flag in conditions of high humidity or precipitation. The heating element is located in the system depending on the design of the compressor.

The compressor 15 itself is located in the upper part of the flagpole basket (Fig. 14). The command unit 113 operates to turn the compressor on or off from the signal from blocks 112, 114 in automatic mode. This block also enables on-off in manual mode.

The compressor has a forced cooling system for its housing. This is ensured by air extraction after the first stage of the compressor. The cooling air, in contact with the compressor housing, cools it and exits through the channel formed by the windows 116 (Fig. 14) in the housing of the mounting basket and the windows 18 (Figs. 1, 14) of the flagpole through the protective nets 19 to the outside. The exit windows 18 (FIGS. 1, 18), as well as the exit windows 17, are located at an angle to the vertical axis so that during precipitation the water cannot get inside the flagpole.

Electromechanical drive

Consists of two systems:

- a drive motor 67 (FIGS. 2, 14) with a gear block 68 (FIG. 14);

- the unit of the tracking system 110 and the control unit 111 (Fig. 8).

The type and power of the electric motor are determined depending on the rated load and its control system. The electric drive has two operating modes - automatic and manual. In manual mode, the drive can be turned on for continuous operation or turned off. This mode is needed for certain moments of the ceremonial - when raising the flag and lowering or rotating it. The inclusion in the manual mode can also be used for technical prevention - after lubricating the bearings 80, 85 (Fig.2, 14) of the base plate and bearing 96 of the base cylinder (Fig.13, 14). Manual activation de-energizes the entire drive system. If the electric drive system does not have an electromagnetic clutch, this can lead to the fixing of the flagpole in the position in which it was at the time of switching off.

In automatic mode, the electric drive 68 (Fig. 14) operates according to the instructions of the servo 110 and the control unit 111 (Fig. 8). The control unit receives a signal from the tracker system unit of the wind vane. This unit controls the position of the weather vane 36 (Fig. 8), when changing the position of which an electrical signal is generated for the control system 111 of the electric drive 68 (Fig. 14). The gear block may have in its design an electromagnetic clutch, which includes a gear block when the power of the drive motor is turned on. The design of the gear block, the electric drive system passing through the grooves 55 (Fig. 9) in the mounting basket and 76 (Fig. 11) in the rotation platform 59 (Fig. 14) on the drive gear 68, is calculated depending on the calculated load on it and correspondence of electric motor power to it 67. Cooling of the electric motor casing and box 115 (FIGS. 2, 14) with electronic units located in the mounting basket is ensured by the movement of air entering the flagpole cavity through windows 17 (FIGS. 1, 14) during operation compressor.

Additional functional blocks included in the flagpole design

Musical accompaniment block (BMS)

BMS is designed to change the force of air supply from the compressor to the flag, consists of block elements that receive an audio signal directly from the microphone or from the music program embedded in its electronic part. The work of the BMS consists in the fact that, depending on the musical melody or program, the speed of air supply through the internal channels of the flagpole and through the nozzles on the flag changes through the processor. The movement of the flag at the same time creates the effect of a “living" flag waving in accordance with the musical and sound moment of the ceremony. BMS can be located at the bottom of the mounting basket with access to it through the technical hatch 2 (figure 2) or in a box with other electronic units 115 (figure 2, 14).

Flag Highlighting Block (FFT)

FFT is designed to provide additional visual effect from lighting of a raised or waving flag, for example, in the dark. FFT consists of a system of sensor sensors and illumination sources 117 (Fig. 1) or spotlights. Illumination sources or projectors working in conjunction with them can be for ordinary or for ultraviolet lighting and are switched on automatically from touch sensors or manually. Ultraviolet lighting is especially effective in the manufacture of a flag from a fluorescent material. Spotlights can have color filters. FFT can be located both on the flagpole and at its base, can be autonomous and located at a distance from the flagpole.

Non-ferrous gas supply unit (BPSG)

BPCG in the cavity of the flagpole is designed to color the air or gas leaving the nozzles in various colors, for which balloons with colored gases or containers with easily sprayed colored powder are introduced into the design of the flagpole. The latter are fed into the air supply channel from the compressor or through separate channels located on the outside of the flagpole. Colored gas cylinders or containers may be located in the hollow parts of the pedestal. When the BOCG is included in the work on the corresponding highways, colored gas or air will be supplied, the colors of which may correspond, for example, to the colors of the flag on the flagpole. Moreover, from the fact that the flag flutters in a colored gas-air environment, the emotional-visual effect is significantly enhanced.

Ceremony visual accompaniment block (BVSC)

BVSC is designed to enhance the emotional-visual effect, which occurs due to the supply of confetti or other light material that can be sprayed under the influence of air jets supplied from a compressor or any other, possibly autonomous, air pressure source into the zone of a waving flag. The specified material is supplied through appropriate channels, spraying is possible simultaneously with flying in the same direction with the flag in conjunction with the operation of the BMS and FFT, BPSG.

Flagpole work with flag waving

The flagpole works as follows. The main mode of operation of the flagpole is automatic. In this mode, all the constituent blocks and structural elements are ready for operation. In manual mode, the flag is hoisted and lowered using a cable passing through the rollers. The cable can be fixed with a mechanical pinch in any position.

In semi-automatic mode, the system operates in the following sequence: first, manually (halfway) the load (counterbalance) rises to the top of the flagpole on half of the cable lines. Prior to this, the load was fixed in its lower position due to being on the annular mechanical limiter. After the load rises, on the other, ordinary, half of the slings of the cable, located opposite the outlet, in its lower part the flag is fixed with clamps. After fixing the flag on the control unit panel, the desired flag raising speed is set.

As necessary, the mechanism turns on, and the lowering of the load begins with the simultaneous raising of the flag located on another - smooth - sling. When the flag reaches its upper point, the operation of the lifting mechanism is turned off, because the load simultaneously "sits" on its restrictive ring.

There is an option to turn off the semi-automatic mode of operation, unlock the lifting mechanism and transfer the entire system to manual control mode.

Other flagpole systems work as follows (in automatic mode).

If the air flow rate is less than the specified one, the signal from the anerubometer turns on the compressor, air is supplied to the outlet nozzles under pressure from the inside of the hollow tube of the flagpole, and from them to the flag, which leads to the flag flying even in the absence of air flow. If the air humidity is higher than the set value, the air heating system is turned on, the flag significantly improves its dynamic properties, because "Drying out" it flutters better. At an air flow rate greater than the set value, the compressor automatically switches off along with air heating, if it was turned on.

When changing the direction of the air flow, a weather vane comes into operation. He issues a command to test the electric drive so that the flagpole unfolds the same angle after the wind vane. Thus, the flagpole, as it were, copies the position of the weather vane, occupying the position when its output nozzles are located so that the air flow from them is added to the external air flow. With this effect, the flag will not overlap the mast of the flagpole.

In manual control mode, the tracking system is turned off. Turning the compressor on or off, as well as heating the air, is done in manual control mode. U-turn or rotation of the flagpole can also be done in manual mode.
