Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figure 1 below, the displacement measuring apparatus of the structure according to the present invention basically, the main body 100 is formed with a receiving space therein; An inclination sensor 200 mounted inside the main body 100 to measure an inclination degree of the main body 100; A horizontal orientation sensor 300 for measuring a change in azimuth of the main body 100 based on a horizontal plane; And a coupling part 400 formed to detachably couple the main body 100 to the structure 1.

Here, the structure 1 to be measured is a concept that collectively refers to natural facilities such as soft ground and slopes, and artificial facilities such as tunnels, bridges, old buildings, security barbed wire, and residential retaining walls.

When the measuring device includes only the tilt sensor 200, if the change of the tilt of the main body 100 occurs in a state in a predetermined direction, the tilt sensor 200 may measure the accurate displacement of the structure, but such as settlement If the orientation of the main body 100 changes with the occurrence of the displacement, there is a problem that the inclination change value of the main body 100 measured by the inclination sensor 200 cannot be regarded as an accurate displacement.

Therefore, the measuring device according to the present invention is provided with a horizontal orientation sensor 300 that measures a change in the orientation of the main body 100 on the basis of a horizontal plane, in addition to the tilt sensor 200, measured by the tilt sensor 200. By correcting the inclination change value of the main body 100 by the azimuth change value of the main body 100 measured by the horizontal orientation sensor 300, there is an effect that more accurate displacement data can be obtained.

Horizontal orientation sensor 300 for measuring the orientation change of the main body 100 on the basis of a horizontal plane may be configured by a variety of configurations, the orientation measurement unit 310 for measuring the orientation change of the main body 100; It is efficient to take a configuration including a horizontal holding unit 320 provided in the main body 100 so that the azimuth measuring unit 310 is horizontal (FIG. 2).

Specifically, the horizontal maintenance unit 320 includes a container 321 is accommodated in the orientation measurement unit 310; It can be implemented by a configuration including a connector 322, such as a thread connecting the receptor 321 and the main body 100, such that the receptor 321 is always located vertically downward with respect to the main body 100 (Fig. 2).

Measuring apparatus according to the present invention, the base 10 coupled to the main body 100; A satellite navigation device (GPS) 20 installed to be rotatable on the base 10; The satellite navigation apparatus 20 further includes a horizontal measuring instrument 2 having a weight 30 coupled to the satellite navigation apparatus 20 so as to be integrated with the satellite navigation apparatus 20 so as to face in the vertical direction. More preferred.

In this configuration, the satellite navigation apparatus 20 allows the absolute coordinates to be known by the signals of the satellites, so that the displacement of the structure can be measured more accurately together with the measured value of the tilt sensor 200. There is this.

In addition, in the above configuration, since the weight 30 is directed toward the earth center, that is, the vertical direction by any gravity change with respect to the absolute horizontal plane H with respect to the earth center, the satellite navigation device integrated with the weight 30 integrally. 20 may also be directed in the vertical direction (FIGS. 3 and 4).

Therefore, even if the measurement apparatus according to the present invention is not installed to be horizontal, the satellite navigation apparatus 20 has the effect that it can always be parallel to the absolute horizontal plane (H) which is a vertical plane.

In addition, by the gravity action of the weight 30, since the satellite navigation apparatus 20 can be directed in the vertical direction, it is possible to reduce the effort for maintaining the horizontality when setting the satellite navigation apparatus 20, convenient and easy This adds the effect of making measurement work easier.

Furthermore, since the weight 30 does not move sensitively to fine vibrations or the like as bubbles as a mass, the vibration movement of the weight 30 can be stabilized quickly, so that the measurement by the satellite navigation apparatus 20 can be performed quickly and easily. The effect can be achieved accurately.

The measuring device according to the present invention comprises a horizontal measuring device 2 having a tilt sensor 200, a horizontal orientation sensor 300, and a satellite navigation device 20 as described above. Since the horizontal movement distance L according to the position change of (1), the inclination change θ of the structure 1 by the inclination sensor 200, the change in orientation by the horizontal orientation sensor 300, etc. can be measured, The combination of these information makes it possible to accurately, easily and quickly measure the three-dimensional behavior of the structure 1 (FIG. 4).

More specifically, the horizontal measuring instrument 2 installed in the measuring device according to the present invention will be described.

First, if the satellite navigation apparatus 20 supports the satellite navigation apparatus 20 so that the satellite navigation apparatus 20 can be rotated about the center of rotation (C) by the gravity action of the weight 30, whatever the structure is taken. It's okay.

However, the base 10 is configured to include a support shaft 12 for supporting the satellite navigation apparatus 20 so as to be able to rotate around the center of rotation (C) at the lower side of the satellite navigation apparatus 20 as shown. More preferred (FIGS. 5-7).

In terms of structure, it can be compactly and simply implemented, and the support shaft 12 can stably support the satellite navigation apparatus 20 from the lower side, and the structural and electrical signal interference with the satellite navigation apparatus 20 is reduced. Because it can be excluded.

The support shaft 12 may take various structures, but it is more preferable to take a structure that can be in point contact with the satellite navigation apparatus 20 so as not to cause structural interference during the rotation of the satellite navigation apparatus 20.

To this end, the satellite navigation apparatus 20 is configured to have a tip portion 22 which protrudes toward the support shaft 12 and becomes the center of rotation C of the satellite navigation apparatus 20, and the upper surface of the support shaft 12. A groove portion 12A into which the tip portion 22 of the satellite navigation apparatus 20 is inserted may be formed so that the satellite navigation apparatus 20 is supported by the support shaft 12 and rotated.

The groove portion 12A of the support shaft 12 is upwardly shaped like a cone so that it can be more firmly coupled with the tip portion 22 of the satellite navigation apparatus 20 without disturbing the rotation of the satellite navigation apparatus 20. It may be more desirable to take a shape that gradually expands.

At this time, as the tip portion 22 of the satellite navigation apparatus 20 is inserted into the groove portion 12A of the support shaft 12, the satellite navigation apparatus 20 depends on the inclination inclination of the groove portion 12A of the support shaft 12. Bar range can be limited, the groove portion 12A of the support shaft 12 is preferably formed in consideration of the rotation range of the satellite navigation device 20.

On the contrary, although not shown, the upper end of the support shaft 12 may be pointed like a needle and inserted into the groove formed in the satellite navigation apparatus 20.

The base 10 may be basically composed of only the support shaft 12, but may further include a housing, a cover, and the like, including the base plate 14 supporting the support shaft 12 as necessary.

On the other hand, the stopper 40 is provided in the base 10 to limit the rotation range of the satellite navigation apparatus 20, it is possible to prevent excessive rotation and departure of the satellite navigation apparatus 20.

The stopper 40 may take various structures. However, more preferably, as shown, the stopper 40 is formed to have an internal space 42 into which the support shaft 12 and the weight 30 can be inserted, and thus the satellite navigation device for the base 10 ( The range of rotation of the satellite navigation apparatus 20 may be limited by causing interference with the satellite navigation apparatus 20 or the weight 30 according to the relative rotation angle of 20).

In this manner, the weight 30 and the support shaft 12 are inserted into the internal space 42 of the stopper 40, thereby making it possible to take advantage of the compactness of the compact design. .

In addition, as the stopper 40 takes the tubular structure, it can take the advantage that the stopper 40 can serve as a case.

Here, the stopper 40 may take various structures depending on which part of the satellite navigation apparatus 20 or the weight 30 causes interference.

In particular, as shown, the stepped portion 42A for limiting the range of rotation of the satellite navigation apparatus 20 is formed in the internal space 42 of the stopper 40, and the weight 30 is the stepped portion of the stopper 40 ( A jaw portion 32 may be formed that may interfere with 42A).

In this case, the stopper 40 may further take advantage of the interference with the weight 30 rather than the satellite navigation apparatus 20, so that no external force is directly transmitted to the satellite navigation apparatus 20.

In addition, since the stopper 40 may be formed to correspond to the weight 30 irrespective of the satellite navigation apparatus 20, the structure of the stopper 40 may be simplified and miniaturized.

In addition, the satellite navigation apparatus 20 may take the advantage that it can take a variety of structures irrespective of the stopper 40.

On the other hand, the inner space 42 of the stopper 40 may be filled with oil (2) to a height that can be locked at least a portion of the weight (30).

Here, as the stopper 40 takes the tubular structure as described above, it can take the advantage that a separate case for filling the oil 2 can be omitted.

Accordingly, the oil 2 may impart resistance to the pendulum movement of the weight 30 during the vibration movement of the weight 30, thereby restraining the fine movement of the weight 30 against fine vibration, It can take the advantage that can be quickly stabilized during the vibration movement of (30).

Thus, the effect that the measurement by the satellite navigation apparatus 20 can be made quickly, easily and accurately can be obtained.

The oil (2) may be any one, but silicone oil may be more suitable because it is stable and free from volatility and viscosity changes and loss due to evaporation.

In particular, the oil 2 may be preferably a silicone oil containing wetting molybdenum (MoS 2 ) is better lubrication action by the fine particles.

The weight 30 may take any structure as long as it can serve as the mass of the pendulum, but it may be more preferably formed to have a hollow 34 into which the support shaft 12 is inserted.

That is, as the weight 30 takes the tubular structure, even if the support shaft 12 is coupled with the center of the satellite navigation apparatus 20, it coincides with the center of the weight 30 and the center of the satellite navigation apparatus 20. The weight 30 and the satellite navigation apparatus 20 can be easily coupled to each other so that it can be.

Therefore, it is possible to take advantage of the design of the overall structure, including the weight 30 is easy.

In addition, as the weight 30 takes the tubular structure, it may take an advantage that the satellite navigation apparatus 20 can be more stably supported.

In addition, by adopting a structure in which the support shaft 12 is inserted into the hollow 34 of the weight 30, a compact design can be advantageous in terms of miniaturization.

In addition, the rotation range of the satellite navigation apparatus 20 may be limited by the interference between the weight 30 and the support shaft 12, and accordingly, the deviation due to excessive rotation of the satellite navigation apparatus 20 may be prevented. Can be taken.

In particular, as indicated by reference numeral '34A' in FIG. 5, the hollow 34 of the weight 30 has a shape in which at least a portion thereof gradually expands away from the satellite navigation apparatus 20. The range of rotation of the device 20 can be easily designed, and when the weight 30 and the support shaft 12 interfere with each other, the weight 30 and the support shaft 12 are in linear contact rather than point contact, thereby making the satellite more stable. It is possible to further take advantage of the fact that the range of rotation of the navigation apparatus 20 can be limited.

The measuring device according to the present invention may further include a connection part 500 connecting the coupling part 400 and the main body 100 so that the inclination of the main body 100 with respect to the coupling part 400 can be adjusted.

Therefore, it is only necessary to install the measuring device on the wall of the structure without the installation of a separate peripheral equipment, the installation work is very simple compared to the conventional, and the equipment can be miniaturized, and the general purpose of use can be expected. 8 to 10.

Here, the connection portion 500 may be implemented by various structures, as shown in the connection portion 500 8, 9 is an embodiment in which the hinge coupling portion 500a is formed between the main body 100 and the coupling portion 400 It is shown.

The hinge coupling part 500a may include an extension part 510 provided with a main body through-hole 511 and extending downward from the main body 100; Coupled portion through-hole 521 is provided in the core portion, the support portion 520 extending to the upper side of the coupling portion 400; It may be implemented by a structure including; a coupling hole 530 through and coupled to the body through hole 511 and the coupling portion through hole 521.

Here, when the coupler 530 takes the bolt-nut fastening structure, by adjusting the angle between the main body 100 and the coupling portion 400 by loosening the tightening, and then tightening the device again by a method of strengthening the tightening again The advantage is that it can be fixed in position.

To this end, as shown in FIG. 10, a plurality of coupling holes 411 are formed at the edge portion, and the base plate portion 410 is formed to be coupled in surface contact with the structure 1. It is preferable to take a configuration such that the 420 is coupled to the structure 1 through the coupling hole 411.

Herein, the coupling member 420 may be applied to various examples by the structure, material, and the like of the structure 1.

When the displacement of the structure measured by the inclination sensor 200 or the like exceeds the allowable range, it is a very dangerous situation. Therefore, the dangerous situation display means 600 for notifying the surroundings by a visual or audio display method includes a main body ( More preferably 100).
