Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cradle for preventing cable from escaping from an underground transmission line,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a cradle for preventing cable escape from an underground transmission line.

Electricity generated by the power plant is transmitted to the substation through the underground transmission line.

The construction method of the underground transmission line through the double ground is the direct burial method, the ducting method for receiving the underground transmission cable in the pipeline after making the pipeline, the power outage method for digging the road in the underground and installing the underground transmission cable in the road.

Among these methods, ducting and electric power transmission are connected to the underground transmission cable through a separate connecting mechanism in the middle when the underground transmission section is long.

At this time, if the connection mechanism connecting the underground transmission cable gets moisture, short-circuit occurs, and it is not possible to transmit power stably through the constant transmission line.

Further, the underground transmission cable connected through the connection mechanism is shaken while external force is applied (for example, an earthquake occurs or a vibration occurs due to construction in the vicinity), and the external force is directly transmitted to the connection portion between the underground transmission cables, Since the cable is disconnected, there is a problem in power transmission.

The ring 72 is movably inserted into the first wire 71. In the present embodiment, the ring 72 may be a square ring or an elliptical ring shape, or may have a shape in which one side is open.

The second wire 73 is connected at one end to the fixing body 82 of the water contact prevention mechanism 80 and at the other end to the ring 72 through the passage portion 81b of the water contact prevention mechanism 80 do.

8 to 14 are views for explaining the operation of the present invention, and the operation of the present invention will be described with reference to FIGS. 8 to 14. FIG.

When water is introduced into the third through hole 13 or the fourth through hole 14 of the manhole 10 or dew is formed on the upper wall of the manhole 10 in the state where the present invention is installed as shown in FIG. 8, water flows along the support wire 70, and this water is directed to the connection mechanism 40.

However, the present invention is such that water directed to the connection mechanism 40 is received in the storage case 81 of the moisture contact prevention mechanism 80. At this time, when water is introduced into the storage case 81 of the moisture contact prevention mechanism 80 at a reference value or more and the humidity in the storage case 81 becomes higher than the reference value, the moisture sensor 92 Senses this and drives the heater body 91 to evaporate and remove moisture in the storage case 81 as shown in FIG. Therefore, water is prevented from flowing into the connection mechanism (40).

In addition, according to the present invention, when water flowing into the storage case 81 of the moisture contact prevention mechanism 80 is larger than water evaporating through the above process as shown in FIG. 10, 11 without being brought into contact with the connection mechanism 40 through the discharge portion 81c and the discharge member 83 of the storage case 81 as shown in Fig. At this time, the discharged water can be discharged through the drain hole provided in the manhole (10).

Here, the connection of the left underground transmission cable L1 and the first coupling mechanism 20 will be described.

After the upper tight contact portion 21b2 and the lower tight contact portion 21b3 of the first joint mechanism 20 are opened as shown in Fig. 12, the end portion of the left underground transmission cable L1, which is drawn into the manhole 10 from the left side, Is inserted into the connecting member 21a of the first coupling mechanism 20 to electrically connect the left underground transmission cable L1 and the connecting member 24 of the first connecting member 20. [

At this time, when the upper close contact portion 21b2 and the lower close contact portion 21b3 of the opened first joint mechanism 20 are placed, the upper close contact portion 21b2 and the lower close contact portion 21b3 of the first joint mechanism 20 are in- (L1) of the left underground transmission cable (L1).

Thereafter, when the upper press mechanism 22 and the lower press mechanism 23 of the first coupling mechanism 20 are driven, the press member 22c of the upper press mechanism 22 of the first coupling mechanism 20 presses the first The pressing member 23c of the lower pressing mechanism 23 of the first joining mechanism 20 presses the upper joining portion 21b2 of the joining mechanism 20 so that the lower joining portion 21b3 of the first joining mechanism 20 So that the linking member 24 between the left underground transmission cable L1 and the first coupling mechanism 20 is stably fixed.

The installation procedure of the right underground transmission cable L2 led into the manhole 10 from the second coupling mechanism 30 and the right side room is the same as that of the first coupling device 20 and the left underground transmission cable L1).

13, when the manhole 10 is shaken as shown in Fig. 13 due to an earthquake or the like in the state of Fig. 1, the connecting mechanism 40 of the present invention is arranged so that the connecting member 24 of the first connecting mechanism 20, And is buffered by the connecting member 34 of the connecting member 30. The connecting member 24 of the first coupling device 20 and the coupling member 34 of the second coupling device 30 provide the buffer mechanism 40 with the buffering force while the connection mechanism 40 is connected to the left underground transmission cable L1) and the right underground transmission cable (L2). That is, the left underground transmission cable L1 and the right underground transmission cable L2 do not separate from the connection mechanism 40. [

In order to confirm by the external manager whether the support wire 70 stably supports the connection mechanism 40 in the state where the present invention is installed as shown in Fig. 1, the manager may set the first and second support mechanisms 50, The head portions 54d and 64d of the rotating mechanisms 54 and 64 of the main body 50 are rotated.

At this time, if the support wire 70 stably supports the connection mechanism 40, the manager can control the first and second support mechanisms 50 and 60 through the rotation mechanisms 54 and 64 of the first and second support mechanisms 50 and 60 It is difficult to move the moving members 53 and 63 of the first and second supporting mechanisms 50 and 60 upward or a large amount of force is required to move the moving members 53 and 63 of the first and second supporting mechanisms 50 and 60 As a matter of necessity, the administrator can feel that the support wire 70 stably supports the connection mechanism 40. 14, when the support wire 70 is cut off and the connection mechanism 40 is not stably supported, as shown in Fig. 14, The moving members 53 and 63 of the first and second supporting mechanisms 50 and 60 can be easily moved upward so that the supporting wire 70 can move the connecting mechanism 40 It can be seen that it is not stably supported.

Therefore, the administrator can confirm whether the connection mechanism 40 is stably supported by the support wire 70 outside the manhole 10 through the above-described operation, without checking the inside of the manhole 10.

On the other hand, according to the present invention, when the manager wires the head portions 54d and 64d of the rotation mechanisms 54 and 64 of the first and second support mechanisms 50 and 60 when the support wire 70 is sagging from the initial installation, The moving members 53 and 63 of the first and second supporting mechanisms 50 and 60 move upward while pulling the supporting wire 70 so that the supporting wire 70 supports the connecting mechanism 40 more stably .
