Furthermore, even when the surroundings are dark at night and difficult to identify, the manhole 1 can be easily found through the lit lamp 90 so that necessary measures can be promptly taken.

On the other hand, when the external force acts on the distribution lines (L1, L2) connected to each other via the metal tube 22 inside the inner body 21, the inner body 21 is thereby either one of the left or right direction At the same time, the reference rod 23 detachably installed at the first guide portion 21a of the inner compartment body 21 is also moved along the guide hole 11c, wherein the reference rod 23 is When the first movement detection sensor 30 passes, the first movement detection sensor 30 is operated to transmit the first movement detection signal to the control unit 60, and the first movement detection sensor 30 receives the first movement detection signal 30 from the first movement detection sensor 30. The controller 60 receiving the movement detection signal outputs an alarm signal and transmits the alarm signal to the transmitter 50. The transmitter 50, which receives the alarm signal from the controller 60, sends the alarm signal to the central control room where the manager resides. Will be sent.

When the reference rod 23 passes the first movement detecting sensor 30 and passes through the second movement detecting sensor 40, the second movement detecting sensor 40 transmits the second movement detecting signal to the controller 60. The controller 60, which receives the second movement detection signal from the second movement detection sensor 40, outputs the dangerous signal to the transmitter 50 and transmits the dangerous signal to the transmitter 50, and receives the dangerous signal from the controller 60. 50 transmits the danger signal to the central control room where the manager resides.

Referring to the operation of the present invention made of the configuration as described above are as follows.

First, the installation process of the insulated wire tube for protecting underground distribution lines according to the present invention will be described.

First, the enclosure 10 is installed on the bottom surface of the manhole 1 via the base plate 14. Then, the distribution line (L1) is inserted into one end of the enclosure 10 in a state where the enclosure 10 is installed and discharged through the other end. Then, the binding brackets 24 are respectively provided at one end of the power distribution lines L1 and L2, and then the power distribution lines L1 and L2 are inserted into the inside through the fastening portion 21c of the inner box body 21 to allow the metal pipe ( 22) The distribution lines L1 and L2 are electrically connected to each other.

When the distribution lines L1 and L2 are connected to each other through the metal tube 22 as described above, the connection lines 24b of the binding brackets 24 installed on the distribution lines L1 and L2 are fastened to each other with the fastening portion 21c. Make sure that (L1, L2) is fixed. When the installation process of the inner compartment 20 is completed, the first guide 21a and the second guide portion 21b of the inner body 21 constituting the inner enclosure 20 constitute the enclosure 10. It is installed to be movable in the first guide groove (11a) and the second guide groove (11b) of the enclosure main body 11, and the elastic body 12 is installed in the second guide groove (11b), respectively.

The fastening member 13 may be fastened to the enclosure body 11 by fastening the fastening member (screw bolts). As described above, after the installation is completed, the connecting pipes 3 and 4 are respectively inserted through both sides of the manhole 1, and the flanges (not shown) of the connecting pipes 3 and 4 of the enclosure 10 are inserted. After facing each other to the flange (11e) is jointed with each other via a fastening member (bolt and nut).

Looking at the operation relationship of the insulated wire tube for underground distribution line protection according to the present invention.

Referring to FIGS. 4 and 5, when the rain falls a lot during the rainy season, even if the manhole 1 is covered by the cover 2, rainwater flows easily into the inside of the manhole 1, and thus, the manhole 1 Is slowly submerged by rainwater.

When the rain rises as described above, the float 15 is lifted along the guide rod 14a of the base plate 14 by the rain, and when the float 15 is raised, the level sensor 50 is pressed. As a result, the water level sensor 50 is operated to output the water level detection signal.

The controller 60 receiving the water level detection signal from the water level detection sensor 50 outputs the water immersion warning signal to the transmitter 50 and simultaneously controls the pump 80 and the lamp 90. In more detail, it is as follows.

First, the transmitter 50 receiving the flood warning signal from the controller 60 transmits a danger signal to the central control room where the manager resides.

The pump 80 controlled by the control unit 60 sucks rainwater introduced into the manhole 1 through the suction pipe 81 and discharges the lifted rainwater to the ground through the discharge pipe 82. The lamp 90 controlled by the controller 60 is turned on to emit light to the surroundings.

Therefore, the manager who resides in the central control room can go to the corresponding manhole (1) through the flood warning signal received and watch the current situation carefully and take follow-up measures in case, so that the distribution line (L1) , L2) can be protected.

Furthermore, even when the surroundings are dark at night and difficult to identify, the manhole 1 can be easily found through the lit lamp 90 so that necessary measures can be promptly taken.

On the other hand, the inner case 20 is usually connected to the distribution lines (L1, L2) is located in the center of the inside of the outer case (10). However, when the external force (left or right) is applied to the distribution lines (L1, L2) this causes the inner box 20 is moved in the direction in which the external force acts, thereby the reference rod (installed in the inner box body 21) 23) also move together, the elastic body 12 is compressed. At this time, when the reference rod 23 passes the first movement detecting sensor 30 in the process of moving along the guide hole 11c of the enclosure body 11, the first movement detecting sensor 30 is the reference rod 23. The first movement detection signal is transmitted to the control unit 60 while operating by the control unit 60, and the control unit 60 receiving the first movement detection signal from the first movement detection sensor 30 outputs an alarm signal to transmit the transmitter 50. The transmitter 50 transmits the alarm signal from the control unit 60 to the central control room where the manager resides.

When the reference rod 23 passes the first movement detecting sensor 30 and passes through the second movement detecting sensor 40, the second movement detecting sensor 40 transmits the second movement detecting signal to the controller 60. The controller 60, which receives the second movement detection signal from the second movement detection sensor 40, outputs the dangerous signal to the transmitter 50 and transmits the dangerous signal to the transmitter 50, and receives the dangerous signal from the controller 60. 50 transmits the danger signal to the central control room where the manager resides.

Therefore, the manager who resides in the central control room can intuitively recognize the current state of the distribution lines (L1, L2) through the received alarm signal or danger signal. There is an advantage of being easier.

The elastic body 12 that has been compressed by the second guide portion 21b of the inner compartment body 21 is removed by the restoring force of the elastic body 12 when the external force applied to the distribution lines L1 and L2 is removed. The second guide portion 21b is returned to its original state. Therefore, since the manager does not have to forcibly move the moved reference bar 23, there is an advantage that it becomes very convenient in managing the facilities.
