Generally, a cable (pipe) is buried in the ground to supply electric power to a residential area or an industrial complex, and the electric wire is wired in the ground. This minimizes the exposure to the underground line, thereby preventing the breakage of the underground wire from external interference There is an advantage to be able to do this, so it is buried in the ground.

As described above, the underground cable, that is, the underground power distribution line is received and protected inside the cable (tube). When the covering of any one of the underground power distribution lines is unplugged, There is a serious problem that the electrical short circuit due to the fire and further the ground distribution line due to the fire can be completely burned.

However, in the case of a cable (pipe) embedded in the ground and receiving an underground distribution cable inside, if the outer surface is corroded by stormwater or sewage after a certain period of time, or if self-destruction occurs due to various external factors, The repair work and the replacement work are performed through the excavation work so as to expose the pipe buried in the outside.

Meanwhile, in the excavation work, a cable (tube) buried in the ground can be quickly and easily taken out to the outside by using a normal forklra. When the knight of the forklra is not aware of the precise position of the cable , The cable (pipe) may be cracked or damaged by the impact when the excavation is carried out through the bucket of the forklrane and the outer surface of the pipe accommodating the underground distribution cable is severely damaged, There is a serious problem that damages the underground distribution line accommodated in the pipe (tube), resulting in interruption of electricity supply.

At this time, an amplifier may be included to increase the output of the speaker unit 600, and the power supply unit 700 may be provided.

The power supply unit 700 is installed so as to be exposed to the ground and includes a storage battery 720 for storing electricity generated from the first and second power generation units 800a and 800b and 5a and 5b, And is configured to supply power to the sensing sensor 400, the transmitter 500, and the speaker unit 600.

Since the transmitter 500, the speaker unit 600, and the power supply unit 700 may be easily damaged by an external impact, it is preferable that the transmitter 500 is installed in a separate protection box (not shown) Not shown) is preferably installed so as to be exposed to the ground for convenience of maintenance and maintenance.

The first and second power generating units 800a and 800b according to the present invention may be configured as shown in FIGS. 5a and 5b in the inner bottom of the buffer support 200 and the upper surface of the second cable body 300, respectively, Respectively.

In this case, the first power generating unit 800a installed in the buffer support 200 may be installed in only a part of the buffer supports 200. Preferably, the first power generator 800a is installed alternately with the settlement detection sensor 400 .

That is, when ten buffer supports 200 are provided, the five subsidence sensors 400 are built in, and the first five power source generators 800a are installed in the remaining five, Are arranged alternately with each other when they are installed at intervals in the longitudinal direction of the vehicle.

More specifically, reference is made to Figures 5a, b.

5A, the first power generator 800a according to the present invention is a method for generating electricity by a pressing force using the piezoelectric element 810. The first power generator 800a includes: A body 221 having a cylindrical shape and having a bar 221 and a lifting bar 221 inserted thereinto and a piezoelectric element 210 connected to the battery 720 via a wire 820, And a spring 230 embedded in the body 210 to provide an elastic resistance force to the lifting bar 221.

When the pressure is generated by the load, the lifting bar 221 presses down the spring 230 by the pressing force, and presses the piezoelectric element 810, and electricity is generated in the piezoelectric element 810 by the pressing force at this time Which is collected by the battery 720 on the electric wire 820 and stored.

Since a large number of such first and second power generation units 800a and 800b generate a large number of power simultaneously, it is possible to generate a large amount of electric power and it is possible to use the power generation unit at all times regardless of the weather.

5B, the second power generator 800b may be formed to have a curvature corresponding to a radius of curvature of the second cable main body 300 and to be fixed to the second cable main body 300 by a bolt A cylinder 840 integrally formed on the upper surface of the supporting piece 830 and a connecting member 840 installed on the inner bottom surface of the cylinder 840 and connected to the battery 720 through a wire 820 A pressing rod 850 fitted in the cylinder 840 so as to press the piezoelectric element 810 and a pressing rod 850 fitted to the pressing rod 850 so as to elastically press the pressing rod 850 An elastic spring 860 interposed between the lower end of the pressurizing rod 850 and the upper end of the cylinder 840 and a lower plate 840 integrally fixed and deformed at the upper end of the pressing rod 850 exposed outside the cylinder 840 And a pressure plate 870 formed to have a curvature corresponding to a radius of curvature of the upper plate 110 so as to be pressed by the upper plate 110 It is configured.

Thus, when the deformation force of the upper plate 110 acts on the pressure plate 870, the pressure plate 870 is pressed and the pressure rod 850 is lowered. As a result, the piezoelectric element 810 is pressed and electricity is generated. Electricity is collected by the battery 720 on the electric wire 820 and stored.

Since the second power generation unit 800b is installed at a plurality of intervals along the longitudinal direction of the second cable main body 300, the electricity generation process described above may be applied to the plurality of second power generation units 800b And it is possible to produce a lot of electric power, and it is very efficient because it can be used at all times regardless of the weather.

Hereinafter, the operation of the present invention will be described.

First, the assembling procedure of the insulating cable will be described. In the state where the lower plate 110 'is disposed on the floor, the buffer support 200 and the first power source 800a are moved along the inner surface length direction of the lower plate 110' Are alternately arranged at predetermined intervals, and then fixed by means of fastening members (screw bolts).

As described above, when the buffer support 200 and the first power generator 800a are installed on the lower plate 110 ', the coupling of the left and right plates 130 and 130' to the coupling groove 112 of the lower plate 110 ' The protrusion 133 is fixed to the upper surface of the buffer support base 200 and the first power generating unit 800a and then the second cable body 300 is fixed.

The insulation cable according to the present invention can be completed by fixing the coupling groove 112 of the upper plate 110 with the coupling protrusion 133 of the left and right plates 130 and 130 '.

At this time, a plurality of second power generating units 800b as shown in FIG. 5 should be installed between the upper plate 110 and the second cable main body 300.

As shown in FIG. 3, the insulation cable having such a structure is embedded in the underground E, and at this time, the settlement detection sensor 400, the transmitter 500 and the speaker unit 600, the power supply unit 700, The storage battery 720 and the battery 720 and the first and second power generation units 800a and 800b may be connected to each other through wires.

As described above, when the assembly is completed, the underground distribution line 1 may be installed on the insulation support 310 of the second cable body 300.

4, when the insulating cable according to the present invention is pressed by the bucket B of the crane, the upper plate 110 is pressed downward by the bucket B to be lowered, The left and right side plates 130 and 130 'of the rubber material supporting the bottom plate 130 are gradually bent.

When the bucket B of the crane presses the upper plate 110 further, the inner surface of the upper plate 110 presses the second power generating unit 800b. As a result, electricity is generated, The second power generating unit 800b presses the outer surface of the second cable main body 300 in which the underground power distribution line 1 is housed again.

The second cable main body 300 is also lowered by the pressing force so that the buffer support 200 and the lifting bar 221 of the first power generating part 800a which are supporting the lifting bar 221 are gradually lowered, The spring 230 supporting the lifting bar 221 is compressed.

Therefore, when the lifting bar 221 is lowered and comes into contact with the downwardly protruding sensor 400, the downward sensor 400 outputs a detection signal, and the output sensed signal is transmitted to the ground And then transmitted to the transmitter 500 and the speaker unit 600, which are exposed.

The transmitter 500 receiving the detection signal from the settlement detection sensor 400 is transmitted to a central control room (not shown) where the administrator resides. The speaker 500 receives the detection signal from the settlement detection sensor 400, A warning sound is emitted to the outside.

At the same time, the first power generator 800a generates electricity by the pressing force, and the generated electricity is transferred to the storage battery 720 and stored.

On the other hand, when the bucket B of the crane for pressing the upper plate 110 is removed, it is restored in the reverse order of the above-mentioned procedure.

As described above, the present invention can produce electricity by itself through the top plate 110 and the second cable body 300, which are deformed by an external force, so that it is possible to supply power regardless of the weather, which is very useful, efficient and semi-permanent .

In addition, it is possible to prevent breakage or breakage of underground power distribution line (1) which may be generated by external force, thereby preventing a safety accident.

The additional embodiment according to the present invention may further improve the structure of the seat 130 and the right side plate 130 'to increase the shock absorbing force so as to further enhance the protection ability of the underground insulation cable from the external force .

To this end, as shown in FIG. 6, the seat plate 130 and the right plate 130 'have a tube shape in which a plurality of chambers CH are formed.

The chambers CH communicate with each other through a relatively small-diameter connection passage PA.

In addition, the chamber CH is filled with air.

At this time, at least one pressure gauge PG is provided on the outer surface of the seat 130 and the right plate 130 'so as to fill the air into the chamber CH and control the internal pressure.

In particular, the pressure gauge PG must communicate with the inner chamber CH to check the internal pressure. For this purpose, an inlet IJ is formed in one of the chambers CH, Shaped gauge passage GP is formed in a portion of the flow passage of the injection port IJ in a direction perpendicular to the inlet port IJ and is curved to form a substantially ' And is connected to the pressure gauge (PG) in a sealed state.

Therefore, when the air is injected into the chamber CH through the injection port IJ, the desired amount of air can be injected while watching the air pressure.

When the seat 130 and the right side plate 130 'are folded in the form as shown in FIG. 4 by the external force, the air flow through the connection passage PA, which is a relatively narrow space, is subjected to a sudden load, So that it is possible to sufficiently absorb and disperse the external force.

In this case, in order to further enhance the cascade buffering function, the connecting passage PA should be formed in such a way that the flow path becomes longer and smaller as it goes from the upper side to the lower side. Particularly, the inlet is wide and the outlet is narrow So that when the abrupt load is applied, the flow of the air is completely blocked so that the tube-shaped seat 130 or the right side plate 130 'does not break.

In other words, PA1 <PA2 <PA3 should be taken in terms of length.

In addition, when the seat 130 or the right plate 130 'is completely folded as shown in FIG. 4, the upper and lower ends of the inner side surfaces of the plates are brought into contact with each other while being in contact with each other. At each stage, a buffer unit 900 such as the one shown in FIG.

The buffer unit 900 includes an upper plate 910 and an upper plate 910 attached to the upper and lower ends of the inner side and the lower side of the left or right plate 130 and 130 ' A coil spring 930 interposed between the top plate 910 and the bottom plate 920 and a coil spring 930 interposed between the top plate 910 and the bottom plate 920. The coil spring 930 is fixed to both sides of the top plate 910, And a fixing hook 950 formed at the upper ends of both side surfaces of the lower plate 920 and engaged with the latching groove 940.

Then, when the lower plate 920 receives an impact, the elastic force of the coil spring 930 is absorbed by the elastic force of the coil spring 930 within the length of the latching groove 940, so that the external force absorbing force due to the elastic deformation increases accordingly.

Thus, the ability to resist the external force is doubled.
