Description

{Balancing System for High Altitude Structure}

The present invention relates to a high-altitude structure balance maintaining system, and more particularly, to a high-altitude structure balance maintaining system capable of improving the safety of high-altitude structures by maintaining balance through displacement compensation by thrust.

In addition to the need to maximize the utilization efficiency of scarce land due to the concentration of manpower and capital cities, high-altitude structures with high altitudes are actively being built as the architectural design technology and construction technology progress.

Typical examples of high-altitude structures built up to date include Burj Halipa in Dubai (163 stories), Shanghai Tower in Shanghai (128 stories), and Lotte World Tower in Seoul (123 levels). The height is expected to be even higher.

Such high-altitude structures are vulnerable to lateral loads such as vibration due to earthquake and wind pressure, and are designed to have structural safety in view of this.

Especially, the high altitude of the high altitude structure makes the natural cycle of the structure shake longer, and it gradually shakes. Therefore, it is different from the period of vibration of the earthquake so that it is not shaken by the earthquake. The higher the altitude and the higher the wind speed is, the stronger the wind speed is, the stronger it is several times that of the ground.

Therefore, although the high-altitude structure is designed and constructed in consideration of lateral loads such as wind pressure, it is necessary to compensate for the displacement caused by the shaking to compensate it quickly and to maintain the balance. In addition, unexpected wind pressure It is necessary to apply an additional system to ensure the safety of the structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a high-altitude structure balance system according to the present invention will be described in detail with reference to the accompanying drawings.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention to those skilled in the art, It should be noted that the present invention can be reduced or exaggerated for the sake of simplicity.

It should also be understood that in the description of the embodiments, when an element is described as being "equipped", "formed", "installed", "coupled", or " May be directly provided, formed, installed, coupled to, or connected to, or coupled to, a computer, but it should be understood that other components may be present in between.

In addition, when describing the embodiments, in the case where it is judged that technical characteristics of the present invention may be unnecessarily blurred as a matter known to those skilled in the art, such as known functions and configurations well known in the art, Description thereof will be omitted.

As illustrated in FIG. 8, since the high altitude structure 100 has a high altitude, the wind receiving area is greatly increased, and the wind speed is very strong compared to the ground. Therefore, the high altitude structure 100 is greatly influenced by the wind pressure A displacement from the balanced state occurs. If the displacement is excessive or prolonged for a long time, the safety of the high altitude structure 100 may be deteriorated while causing discomfort and anxiety of the resident.

Here, the high-altitude structure to which the balance-maintaining system according to the present invention is applied includes a space elevator, a tower crane, a high-altitude dust collector, an air cleaner, And the like, without departing from the scope of the present invention.

In addition, the equilibrium state may mean a fixed state where an elevation structure is maintained when the elevation structure is vertically erected or when a lateral load due to wind pressure or the like is not received.

The balance maintaining system (hereinafter referred to as " balance maintaining system ") according to the present invention is a system for balancing the high-altitude structure System.

 The balance maintaining system of the present invention may include a displacement sensing unit 10, a compensation thrust unit 20, and a balance control unit 30, as illustrated in the block diagram of FIG.

First, when the high-altitude structure 100 is displaced from the balanced state due to lateral load such as wind pressure (W), earthquake or the like and a displacement occurs, the displacement sensing unit 10 senses the displacement and controls the balance control unit 30 Signal.

The displacement detection unit 10 may be a GPS system.

The GPS system is provided with a single or a plurality of GPS receivers at predetermined positions above the high altitude structure 100, and detects the displacement by detecting the current position of the GPS receiver through communication with the GPS satellite.

Detection of displacement of high-altitude structures through the GPS system is disclosed in detail in various prior documents such as the above-mentioned prior patent No. 10-1267107, and is already applied to monitoring various high-altitude structures such as Burj , And the technology has been developed to have precision up to mm units at present.

The displacement sensing unit 10 may sense a displacement using a tilt sensor that senses a tilt and transmits a signal.

That is, a single or a plurality of tilt sensors are provided to sense tilt in various directions at a predetermined upper position of the high-altitude structure, and the tilt sensor detects the displacement by measuring the tilt at the installed tilt sensors.

The displacement sensing technology through the GPS system or the tilt sensor described above is well known in the art. The displacement sensing unit 10 of the present invention includes the GPS system, the tilt sensor, But it is also possible to apply both the sensing through the GPS system and the sensing through the tilt sensor at the same time.

Next, the compensation thrust section 20 performs a function of restoring the high-altitude structure 100 to a balanced state by providing a thrust F in a direction for compensating displacement in accordance with the control of the balance maintaining control section 30 do.

That is, when the high-altitude structure 100 is shaken due to lateral load applied to the high-altitude structure 100 due to the wind pressure (W) due to wind or the like, the compensation thruster unit 20 compensates the displacement So that the high altitude structure 100 is restored to the balanced state by pushing the high altitude structure 100 in the direction opposite to the lateral load.

The compensation thrust section 20 includes a thrust device 21 for generating a thrust. The thrust device 21 may be applied to any device that generates thrust F without limitation.

For example, as shown in FIG. 3, the thrust device 21 may be a booster device that generates a thrust F by accelerating a high-energy, high-pressure fluid backward by combustion or compression of fuel, A propeller for accelerating the air flow backward by rotation and generating the thrust F by using the recoil as shown in Fig. 4 or the like can be applied to the engine, the jet engine, the compression injection device, and the like.

The compensation thrust section 20 for generating the thrust F and pushing the high altitude structure 100 in the displacement compensation direction is installed in the high altitude structure 100 itself as illustrated in FIG. And can be installed in various structures.

3 and 4, the compensation thruster unit 20 may be installed in a structure in which a plurality of thrusters 21 are arranged at a predetermined position on the upper side of the high-altitude structure 100.

At this time, the number of the thrusters 21 and the mounting direction correspond to the direction in which displacement may occur depending on the shape of the high-altitude structure 20. [

For example, as illustrated in FIGS. 3 and 4, when the high altitude structure 100 is a quadrangle, displacement may occur in four directions of the front, rear, left, and right directions. The four torsion devices 21 are arranged at right angles on four sides of the high altitude structure 100 so that the high altitude structure 100 can be arranged in a hexagonal or octagonal shape , Six or eight thrusters 21 are arranged along six or eight surfaces, and if they are curved, they can be arranged properly in consideration of the displacement direction.

The plurality of thrusters 21 arranged in this manner generate thrust F selectively in accordance with the displacement direction under the control of the balance maintaining controller 30. [

3 (a), the compensation thrust section 20 may be installed on the outer surface of the high-altitude structure 100 as an independent structure. In addition, as shown in FIG. 3 (b) It is also possible to provide a structure in which it is drawn inwardly so as not to protrude to the outside of the high-altitude structure 20 for aesthetic appearance of the high-altitude structure 20.

3 (a), when the compensating thrust unit 20 is installed in an independent structure on the outer surface of the high altitude structure 100, the compensating thrust unit 20 is not fixed at a specific position, The thrust section 20 may be vertically movable.

4 (a), the thrust force unit 20 may generate thrust F by installing a single thrust device 21 in one direction, A plurality of thrusters 21 may be arranged in one direction to generate the thrust F as illustrated in FIG.

Unlike the structure in which the plurality of thrusters 21 are arranged in a direction in which the plurality of thrusters 21 can be displaced to compensate for displacement in various directions, the compensation thruster 20 has a single thrust device 21, So that the thrust direction can be switched.

5, the compensation thrust section 20 is composed of a single thrust device 21 installed at the center of a certain layer of the high altitude structure 100, So that the thrust force F is generated in a direction to compensate the displacement while horizontally rotating the thrust device 21 corresponding to the direction in which the displacement is generated.

When the thrust device 21 is driven in the state that the compensation thrust section 20 is installed on the high altitude structure 100, the thrust F due to the reaction force is generated in the horizontal direction, and the high altitude structure 100 is compensated for displacement So that the high-altitude structure 100 can be recovered quickly and efficiently to a balanced state.

Next, the balancing control unit 30 controls the compensation thrust unit 20 according to the detection of the displacement sensing unit 10 so that the balance of the high-rise structure 100 is maintained.

The balance control unit 30 may be implemented as an example including the balance release determination unit 31, the displacement direction determination unit 32, and the thrust control unit 32, as shown in FIG.

The balance disparity determining unit 31 may calculate a displacement value according to the sensed information transmitted from the displacement sensing unit 10, and compare the sensed information with the set reference value to determine that the disparity is equal to or greater than the reference value.

Here, the reference value as a criterion for discrimination can be appropriately set in consideration of the height and structure of the high altitude structure 100, the risk of hindering the structural safety, and the degree of inconvenience of residents.

The displacement direction determination unit 32 determines the direction of displacement by detecting the GPS or the tilt sensor of the displacement sensing unit 10 that transmitted the sensing information when it is determined to be out of balance in the balance displacement determination unit 31. [

The thrust control unit 33 controls the compensation thrust unit 20 to generate thrust F of a suitable force in a direction to compensate displacement according to the displacement direction discrimination unit 32. [

For example, in the case where the compensation thrust section 20 has a structure in which a plurality of thrust devices 21 are arranged, as in the above-described example, the thrust control section 33 controls the thrust device 21 in a direction It is possible to control the compensation thrust section 20 such that a thrust F is generated in a direction to compensate displacement by applying a drive signal so that only the thrust device 21 of the thrust device 21 is driven.

When the compensation thrust section 20 is constituted by a single number of horizontally rotatable thrust devices 21 as in the above-described example, the thrust force control section 33 controls the thrust device 21 in the direction opposite to the displacement direction, It is possible to control the compensation thrust section 20 such that a thrust F is generated in a direction to compensate displacement by applying a drive signal after applying a rotation signal.

Here, the thrust control unit 33 controls the driving of the thrust device 21 so as to perform continuous driving, and applies a driving signal in the form of a pulse so that the thrust device 21 is repeatedly and discontinuously driven Or the like.

When the thrust device 21 is tilted in the northwest direction when the thrust device is provided in the four directions of the south, south, south, east, and west of the structure, the thrust device 21 And the degree of thrust generation in each direction may be appropriately adjusted in accordance with the subdivision in the tilted direction.

Hereinafter, a balance maintaining process of the high-altitude structure 100 by the balance-maintaining system of the present invention will be briefly described.

First, the displacement sensing unit 10 continuously detects whether or not the high altitude structure 100 is displaced from the balanced state, and transmits the sensed information to the balance maintaining control unit 30.

Then, the balance control unit 30 determines whether the balance is released or not, and if the displacement is within the normal range, which is equal to or less than the reference value, the control unit 30 does not generate the thrust and keeps the sensing state.

When the high altitude structure 100 is shaken and a displacement of more than the reference value is generated in the one direction by the wind pressure wind W due to the wind in this one direction, the balance control unit 30, according to the detection information transmitted from the displacement detection unit 10, Determines the balance deviation and the displacement direction.

The balancing control unit 30 selects the thrust device 21 to generate the thrust F from the compensation thrust unit 20 or horizontally rotates the thrust device 21 in the corresponding direction, 21 are driven.

7, the driven thrust device 21 accelerates the fluid or air in the outward direction of the high-altitude structure 100 to generate the thrust F in the transverse direction opposite to the wind pressure W And the high-altitude structure 100 is pushed toward the direction compensating the displacement by the thrust F, thereby compensating for the displacement.

While the displacement compensation is performed by the thrust F, the balancing control unit 30 continuously determines the displacement according to the sensing information transmitted from the displacement sensing unit 10, and by compensating by the thrust, The driving of the thrust device 21 is stopped when the motor 100 is recovered. Of course, in the case where the value is equal to or smaller than the reference value as described above, the thrust device 21 may be decelerated so that the thrust is weakened, and the control may be stopped when the displacement value is finally equal to zero.

As described above, in the balance maintaining system of the present invention, the thrust force F compensating for the direct displacement is applied to the high altitude structure 100 in which the balance deviation is caused by the displacement due to the lateral load such as wind pressure (W) 100) can be quickly restored to a balanced state, thereby improving the structural safety of the high-altitude structure and effectively relieving the inconvenience and anxiety of residents.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the technical scope of the invention is not limited to the disclosed exemplary embodiments and drawings, It will be understood that the modified equivalent structure is not limited to the scope of the present invention.
