FIG. 17 is a schematic assembly perspective view of the winding module 1 provided in the rockfall monitoring device 100 of the present invention, and FIG. 18 is a schematic exploded perspective view of the winding module 1 of FIG. 17 have. 19 is a schematic enlarged cross-sectional view of the line AA of FIG. 18 showing the internal configuration of the take-up module 1 according to the present invention, and FIG. 20 is a take-up reel 12 of the take-up module 1 in the present invention. A schematic perspective view showing a state in which the wire 10 is wound is shown, and FIG. 21 is a schematic exploded perspective view showing a state in which the first and second flat members 12a and 12b of the winding reel 12 are assembled Is shown.

In the present invention, the winding module 1 is a winding reel 12 in which the wire 10 is wound by forming a layer so as to form a single plane in a concentric circle shape, and the winding reel ( 12), and a spring 14 that applies a continuous rotational force to the rotational shaft 20 so that the wire 10 is wound around the reel 12 while tension is applied at the lower end of the rotational shaft 20. ). In the drawings, indicated by reference numeral 21 is a ring member 21 including bearings installed on the upper and lower ends of the rotating shaft 20 as necessary, and indicated by reference numeral 13 is a winding module to support the above-described members from below. It is a support member 13 provided as needed at the inner lower end of (1). Reference numeral 11 denotes a cover 11 on which the reel 12 is installed, and in the case of the embodiment shown in the drawing, the cover 11 is composed of a member separated up and down, and in the inner space of the cover 11 The take-up reel 12 is arranged rotatably.

The winding reel 12 provided in the winding module 1 is wound so that the wire 10 forms a single layer in a concentric circle shape and can be unwound as illustrated in the drawing. In particular, in the present invention, the winding reel 12 has a structure in which the first and second flat plate members 12a and 12b are arranged to face up and down at an interval equal to the diameter of the wire 10 as illustrated in the drawing. Have. The rotation shaft 20 penetrates the center of the take-up reel 12 and is integrally coupled with the take-up reel 12 so that it rotates interlockingly when the take-up reel 12 rotates due to displacement of rockfall.

A spring 14 that applies a rotational force to the rotational shaft 20 so that a constant tension is continuously applied to the wire 10 may be provided at the lower end of the rotational shaft 20 in a form surrounding the rotational shaft 20. If the wire 10 is sagging due to its own weight in the state before the rockfall displacement occurs, the wire 10 is pulled due to the rockfall displacement as it is due to the rotation of the winding reel 12 and the rotation shaft 20. It may not be reflected. In order to prevent this, the wire 10 must be in a state in which a certain tension is applied in the normal monitoring state in which rockfall displacement does not occur. As shown above, a spring 14 is provided to continuously apply a rotational force to the rotating shaft 20. , The wire 10 is not sagging and it is possible to maintain a state in which a predetermined tension is constantly applied.

As described above, the take-up reel 12 of the present invention has a structure in which the wire 10 is wound around the center of the take-up reel in a concentric circle to form a single layer in one horizontal plane. In the embodiment illustrated in the drawing, the winding reel 12 includes two flat members, that is, the first and second flat members 12a and 12b, which are arranged to face up and down at an interval equal to the diameter of the wire 10. Since it has a structure, when the wire 10 is wound around the center of the winding reel 12, there is only one layer of the wire 10 in the vertical direction in the gap between the first and second flat members 12a, 12b, The first and second flat plate members 12a and 12b form a concentric circle in the horizontal plane and are wound in a sequentially stacked state. FIG. 8 is a schematic enlarged view of the circle B portion of FIG. 5 showing in detail a portion in which the wire 10 is wound between the first and second plate members 12a and 12b. Since there is only a gap corresponding to the diameter (thickness of the wire) of the wire 10 between (12a, 12b), the wire 10 is between the first and second plate members 12a, 12b as shown in FIG. In the vertical direction, there is only one layer, and in the horizontal direction, the center of the winding reel 12 is wound in a form that is sequentially stacked while forming a concentric circle in one plane.

In the rockfall monitoring apparatus 100 of the present invention, by measuring the displacement of the wire caused by the rockfall displacement, it is determined whether or not the rockfall occurs, and the occurrence of the rockfall is recognized. That is, when rockfall displacement occurs due to rockfall, the wire 10 is pulled, and by measuring the displacement of the wire that is pulled and unwound from the winding reel 12, the rockfall monitoring system 200 is used. It is transmitted, and the abnormal symptom determination module 204 of the rockfall monitoring system 200 calculates the rockfall risk based on the measured wire displacement and compares it with a predetermined management reference value in real time, or the measured value of the wire displacement itself as a rockfall risk. It is considered and compared in real time with the pre-determined management standard value, and if the management standard value is exceeded, a signal for countermeasures against the risk of rockfall, such as a danger warning, is issued. Therefore, it is important to accurately measure the displacement of the wire caused by the rockfall displacement in order to increase the reliability of recognizing the occurrence of a rockfall. In the present invention, by counting the number of rotations of the winding reel 12 while the wire 10 is unwound, the displacement of the wire due to rockfall displacement is measured. In order to improve the reliability and precision of rockfall monitoring, the wire It is very important that the generated displacement is reflected as it is with the rotation of the reel 12 and the rotation shaft 20 coupled thereto without distortion.

Figure 9 is a schematic perspective view showing that the wire is wound in various forms in the center of the winding reel 12, Figure 9 (a) is a configuration in contrast to the present invention, the center of the winding reel is a predetermined vertical A conventional general case is shown in which the wire is irregularly wound around the center of the reel because it has a length, and in (b) of FIG. 9, the wire is stacked in the vertical direction at the center of the reel having a predetermined vertical length. It is shown in the case that the wire is regularly wound in Fig. 9 (c), and the wire 10 forms one layer in accordance with the present invention and forms a concentric circle in one horizontal plane and is wound around the center of the take-up reel 12. Is shown.

In the conventional general winding reel, since the center of the winding reel 12 has a predetermined vertical length, as shown in Fig. 9 (a), the wires are irregularly overlapped with each other and are frequently wound around the center of the winding reel. Will occur. In the case of a wire wound on another wire, the length of winding the center of the reel once is larger than the circumference of the center of the reel. Therefore, in this case, even if the wire is actually drawn as long as the reel can be rotated once, The take-up reel cannot be rotated once. That is, the length of the wire withdrawn (displacement of the wire) and the number of rotations of the reel due to this do not coincide with each other, which means that counting the number of turns of the reel does not reflect the withdrawn length of the wire as it is. it means. Therefore, as shown in (a) of FIG. 9, when the wires are irregularly superimposed on each other and wound around the center of the reel, the displacement of the wire cannot be accurately measured by counting the number of rotations of the reel. The accuracy and reliability of determining and recognizing whether rockfall has occurred based on the measured value of the displacement of the wire is greatly reduced.

On the other hand, in the present invention, as shown in (c) of FIG. 9, the center of the winding reel 12 is wound in a form in which only one layer of the wire 10 is present in the vertical direction while forming a concentric circle in the horizontal direction. . Therefore, when a wire displacement occurs so that the wire 10 is unwound and taken out from the take-up reel 12, this is immediately reflected in the rotation of the take-up reel 12. The thickness of the wire 10 is a value known in advance, and it is possible to know in advance how many layers the wire 10 is concentric and stacked in a normal monitoring state in which rockfall does not occur. Therefore, when counting the number of turns of the winding reel 12 according to the withdrawal of the wire 10, a known value for the thickness of the wire 10 and the number of layers on which the wire 10 is horizontally stacked is used. It is possible to know by calculating the exact value of the length of the wire 10, that is, the displacement of the wire. As described above, in the present invention, the displacement of the wire is directly reflected in the rotation of the winding reel 12 without distortion, and when the number of rotations of the winding reel 12 is counted, an accurate measurement value of the wire displacement can be known. Accordingly, the accuracy and reliability of determining and recognizing whether rockfall has occurred based on the measured displacement value of the wire is exhibited.

On the other hand, in the present invention, the wire 10 has the following additional advantageous advantages through a configuration in which the wire 10 forms a concentric circle in one horizontal plane to form one layer and is wound around the center of the take-up reel 12.

As shown in (b) of FIG. 9, when the wires are regularly wound in a stacked form in the vertical direction of the center of the winding reel, unlike the case shown in (a) of FIG. 9, the wire is connected to another wire. Since the wire is not wound in a superimposed state, the length (displacement of the wire) from which the wire is drawn out and the number of rotations of the take-up reel thereby coincide with each other. However, in order to wind a wire of a required length, the center of the take-up reel must have a considerable vertical length, thereby increasing the size and weight of the take-up reel. In contrast to the present invention, when a wire of the same length is wound around the center of a winding reel, in the case of the present invention shown in Fig. 9(c), the central vertical length of the winding reel 12 is sufficient if the thickness of one wire is However, in the case shown in (b) of FIG. 9, since the wires must be stacked in a plurality of layers in the vertical direction, the central vertical length of the winding reel must be as long as the number of stacking, and the scale and weight of the winding reel are increased accordingly. It is done.

As the scale and weight of the winding reel 12 are increased in this way, the scale of the spring 14 for applying a rotational force to the winding reel 12 must also be increased so that a constant tension is continuously applied to the wire 10 by that amount. (1) There is a problem that the size and scale of (1) increase. As described above, in order to prevent the wire 10 from sagging, a spring 14 is required to apply a rotational force to the winding reel 12. As shown in (b) of FIG. 9, the wires are stacked in a plurality of layers in the vertical direction. If the scale and weight of the winding reel are increased due to the increase in the vertical length of the center of the winding reel, the scale of the spring for applying the rotational force to the winding reel is inevitably increased, and eventually the size and scale of the winding module increase. It becomes.

On the other hand, in the case of the present invention having the configuration shown in (c) of FIG. 9, a wire 10 having a sufficient length can be wound even without increasing the central vertical height of the winding reel 12 at all. That is, unlike the case shown in (b) of FIG. 9, in the present invention, in order to wind the wire 10 of the required length, it is not necessary to increase the vertical length of the center of the winding reel 12 at all. As in (b), the scale and weight of the take-up reel 12 do not increase, but rather the scale and weight of the take-up reel 12 can be reduced.

In particular, when the size and weight of the take-up reel 12 is reduced, the size of the spring 14 for applying a rotational force to the take-up reel 12 and the size and size of other members related thereto can be reduced. In implementing the rockfall monitoring device 100 to have a withdrawal length, a very useful advantage is exhibited that the reel 12 can be downsized. In addition, the rockfall monitoring device 100 of the present invention has a simple configuration and can be manufactured in a small size, so it is easy to fix and mount on a steep slope 101, as well as in an area to be measured where the winding module 1 is fixedly installed. Since it hardly burdens the load, it is possible to prevent the risk of rockfall.

In configuring the reel 12 in the present invention, the first plate member 12a and the second plate member 12b may be assembled and coupled to each other by a screw method. The first and second flat plate members 12a and 12b of the take-up reel 12 as in the embodiment shown in FIG. 7 have a convex coupling portion having a threaded thread on the outer circumferential surface and a concave coupling portion having a screw thread on the inner circumferential surface, respectively, so that they are engaged with each other. It can be manufactured as, in this case, there is an advantage in that it is easy to manufacture the member according to the design. Of course, unlike those illustrated in the drawings, the first and second plate members 12a and 12b may be provided with concave coupling portions and convex coupling portions oppositely. In addition, as illustrated in the drawings, the inner edges of the first and second flat portions are formed in a chamfered shape, so that when the wire 10 is wound at an angle, it is easily drawn out without bending by the edge of the flat plate member, It is also possible to prevent damage to the wire 10 and maintain the accuracy of the measured value. The drawings and the above-described detailed description relate to an embodiment of the take-up reel 12 of the present invention, and the shape of the take-up reel 12 and a coupling method between members are not limited thereto.

In addition, as illustrated in the drawing, on one side of the winding module 1, a guide for preventing the bending of the wire 10 by guiding the wire 10 from the inner hollow to the opening through which the wire 10 is drawn out. It is preferable that the member 30 is installed. Although the guide member 30 is illustrated in the shape of a circular tube in the drawing, it may be manufactured in another shape having a hollow. When the guide member 30 is provided, the wire 10 is prevented from being bent due to the difference in height between the installation position of the rockfall monitoring device 100 and the fixed point P, thereby preventing damage to the wire 10 There are advantages that can be prevented.

The number of rotations of the rotation shaft 20 described above is counted by the measurement module 2 provided on the upper part of the winding module 1. The measurement module 2 of the present invention counts the number of rotations when the reel 12 and the rotation shaft 20 rotate due to displacement of the rockfall. That is, as described above, one end of the wire 10 is fixed to the fixed point P of the slope 101, and the other end is wound around the take-up reel 12, when the displacement of the rockfall occurs, the wire 10 is The winding reel 12 is rotated by unwinding, and the measurement module 2 counts the number of rotations of the rotating shaft 20 rotated together with the winding reel 12.

In the inner space of the measurement module 2, a known rotation speed measurement means is provided, for example, a potentio-meter, which is a type of variable resistance, or an encoder whose code value is changed may be used as the rotation speed measurement means. . Such rotational speed measuring means can be stably fixed by an additional support member in the measuring module 2 of the present invention. The rotational speed measuring means used in the present invention is capable of multi-rotational measurement, and has the advantage of accurately measuring the length change of the wire 10 by increasing the measurement rotational speed. The measuring module 2 of the present invention may include a converter for converting an analog signal into a digital signal and transmitting it to a collecting device, or may include a digital rotational speed measuring means without the use of a converter.

The measurement module 2 may be configured to perform only the function of simply measuring the number of revolutions of the winding reel 12 and the rotating shaft 20 and transmitting it to the management server through a wireless or wired communication network. , It is also possible to further perform a function of calculating the displacement of the wire by using the measured rotation speed measurement value of the winding reel 12 and the rotation shaft 20 and transmitting the calculated value to the management server. Of course, when the measurement module 2 is equipped with an arithmetic device, the arithmetic device has a function of comparing the calculated value of the displacement of the wire with a predetermined reference value, and recognizing that a rockfall occurs when the displacement of the wire exceeds the reference value. May be.

Therefore, according to the rockfall monitoring apparatus 100 according to the present invention, the length change of the wire 10 due to the displacement of the rockfall on the slope 101, that is, the displacement of the wire is measured through the measurement module 2, and the value is measured. By transmitting it to the manager in real time, the user can monitor the displacement of the rockfall based on the collected measurement values, predict the progress of the rockfall, and react quickly. Of course, the rockfall monitoring device 100 itself may be provided with various means (for example, a verbal alarm, a lamp alarm, etc.) to warn of the risk of rockfall, so that the risk of rockfall may be notified in various forms at the installation site. Furthermore, the rockfall monitoring device 100 of the present invention further includes an additional measuring means capable of measuring temperature, inclination, etc., so that temperature, inclination, and orientation that can affect the length change measurement value of the wire 10 It is also possible to improve the accuracy of measurement by minimizing possible errors in measuring the displacement of rockfall by making it possible to measure the amount of change in the back and correcting the change in length of the wire 10.

As described above, the rockfall monitoring device 100 of the present invention can be installed and used alone, as well as when rockfall is expected in a wide area on the slope 101, a plurality of rockfall monitoring devices 100 are used on the slope 101 ), it can be used as a system method that measures and monitors the displacement of rockfall by section by installing it at intervals over multiple sections.

The second bracket 37 may be formed in a'c' shape as illustrated in the drawing, and when the mounting hole 39 is formed on the bottom surface, the rockfall monitoring device 100 is connected to the rockfall monitoring device 100 through a coupling means such as an anchor bolt. It may be fixedly installed on the slope 101.

In particular, a plurality of angle adjustment holes 32 are formed in the first bracket 31, and a single arc-shaped long hole 38 is formed in the second bracket 37, so that the first and second brackets are By selecting the angle adjustment hole 32 so that the (31, 37) achieves the desired angle and fastening it through the long hole 38 and the fastening means 40, the installation angle and posture of the rockfall monitoring device 100 on the slope 101 It can be fixed and installed. When installing the rockfall monitoring device 100, in a state in which the fastening means 40 mounted in the through holes 35a, 35b are temporarily fastened, the first to second brackets 31 and 37 are rotated to adjust the angle, and , It is to fix the angle by completely fastening the fastening means 40. 25 and 26 are only examples, and the shapes of the first and second brackets 31 and 37 and the shape or number of holes provided are not limited thereto.
