At this time, the transmitter 500, the speaker unit 600 and the power supply 700 may be easily damaged by an external impact, it is preferable to install in a separate protective enclosure (not shown), and also the protective enclosure ( Not shown) is preferably installed exposed to the ground for the convenience of management and maintenance.

In such a configuration, the first and second power generating units 800a and b according to the present invention have the same shape as that of FIGS. 5A and B at the inner bottom of the buffer support 200 and the upper surface of the second cable main body 300. Is installed.

In this case, the first power generation unit 800a installed in the buffer support 200 may be installed only on a part of the plurality of buffer support 200, and preferably alternately with the settlement detection sensor 400. Can be.

That is, when the buffer support 200 is provided with 10, the settlement detection sensor 400 is built in five, the first power generation unit 800a is built in the remaining five, they are the second cable body 300 It is particularly preferable that they are installed alternately with each other when installed at intervals in the longitudinal direction.

More specifically, reference is made to FIGS. 5A, B.

As shown in FIG. 5A, the first power generation unit 800a according to the present invention uses a piezoelectric element 810 to generate electricity by a pressing force. The first power generation unit 800a receives a load of the second cable main body 300. Bar 221, the body portion 210 of the cylindrical shape in which the lifting bar 221 is inserted, the piezoelectric element is installed on the inner bottom surface of the body portion 210 and connected to the storage battery 720 through the wire 820 810 and a spring 230 embedded in the body portion 210 to provide elastic resistance to the elevating bar 221.

Thus, when pressure is generated by the load, the lifting bar 221 descends while compressing the spring 230 by the pressing force to press the piezoelectric element 810, and the piezoelectric element 810 generates electricity by the pressing force. In this case, the electric current is collected and stored in the storage battery 720 on the wire 820.

This process can be produced by a large number of simultaneous multiple times by the plurality of first power generation unit (800a) can produce a lot of power, it is possible to always use regardless of the weather is very efficient.

In addition, the second power generator 800b is formed to have a curvature corresponding to the curvature radius of the second cable main body 300, as shown in FIG. 5B, and has an arc shape that is bolted to the second cable main body 300. The support piece 830 of the, the cylinder 840 integrally formed on the upper surface of the support piece 830, and is installed on the inner bottom surface of the cylinder 840 and connected to the storage battery 720 through the wire 820 A piezoelectric element 810, a pressure rod 850 fitted inside the cylinder 840 to pressurize the piezoelectric element 810, and a state in which the piezoelectric element 810 is fitted to the pressure rod 850 to elastically pressurize the pressure rod 850. The elastic spring 860 interposed between the lower end of the pressurizing rod 850 and the upper end of the cylinder 840 and the upper plate integrally fixed and deformed to the upper end of the pressing rod 850 exposed outside the cylinder 840 ( It includes a hydraulic plate 870 having a curvature corresponding to the radius of curvature of the upper plate 110 to be pressed by the 110. It is configured.

Thus, when the deformation force of the upper plate 110 acts on the hydraulic plate 870, the hydraulic plate 870 is pressed down to lower the pressure rod 850, thereby pressing the piezoelectric element 810 to generate electricity, which The electric wires 820 are collected and stored in the storage battery 720.

In this case, since the plurality of second power generating units 800b are installed at intervals along the length direction of the second cable main body 300, the above-described electricity generation process may be performed on the plurality of second power generating units 800b. It is possible to produce a lot of power by generating a lot of simultaneous at the same time, and it is very efficient because it can be used all the time regardless of the weather.

Referring to the operation of the present invention made of such a configuration as follows.

First, the assembling procedure of the insulated 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 generating unit 800a are arranged along the inner surface longitudinal direction of the lower plate 110'. After arranging them alternately at predetermined intervals, fix them by means of fastening members (screw bolts).

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

In addition, when the coupling grooves 112 of the upper plate 110 are fixed by the coupling protrusions 133 of the left and right plates 130 and 130 ', the insulation cable according to the present invention can be completed.

At this time, between the upper plate 110 and the second cable main body 300, a plurality of second power generation unit 800b as shown in FIG.

Insulated cable having such a structure, as shown in Figure 3, it may be buried in the ground (E), at this time, the settlement sensor 400, the transmitter 500 and the speaker unit 600, the power supply unit 700 The storage battery 720, and the storage battery 720 and the first and second power generation unit (800a, 800b) is preferably connected to each other via a wire.

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, respectively.

In this state, as shown in FIG. 4, when the insulated cable according to the present invention is pressed by the bucket B of the fork lane, the upper plate 110 is pressed downward by the bucket B, and the upper plate 110 is lowered. The left and right plates 130 and 130 'of the rubber material which were supporting the bent gradually.

As described above, when the bucket B of the fork lane presses the upper plate 110 further, the inner surface of the upper plate 110 pressurizes the second power generation unit 800b, thereby generating electricity as well as generating electricity. Is stored in the storage battery 720, and the second power generation unit 800b again presses the outer surface of the second cable body 300 in which the underground distribution line 1 is accommodated.

In addition, the second cable body 300 is also lowered by the pressing force, whereby the cushioning support 200 and the elevating bar 221 of the first power generating unit 800a, which were supporting it, are gradually lowered. The spring 230 supporting the elevating bar 221 is compressed.

Therefore, when the lifting bar 221 descends and comes into contact with the settlement detection sensor 400 protruding upward, the settlement detection sensor 400 outputs a detection signal, and the output detection signal is grounded via a wire. The transmitter 500 is exposed to the transmitter 500 and the speaker unit 600.

The transmitter 500 receiving the detection signal from the settlement detection sensor 400 is transmitted to the central control room (not shown) where the manager resides, and the speaker unit 600 receiving the detection signal from the settlement detection sensor 400. Emits a warning sound to the outside.

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

On the other hand, when the bucket (B) of the fork lane pressing the upper plate 110 is removed is restored in the reverse order of the above-mentioned order.

As such, the present invention is able to produce electricity by itself through the upper plate 110 and the second cable body 300 which is deformed by external force, and thus can supply power regardless of the weather, which is very useful, efficient, and semi-permanent. .

In addition, it is possible to prevent the breakage or damage of the underground distribution line (1) that can be generated by external force in advance to prevent safety accidents.
