Description

Underground transmission line support device for convenient management of underground transmission lines

The present invention relates to a device for supporting an underground transmission line, which is convenient for managing the underground transmission line.

A transmission line is an electric wire for transmitting electricity, and it is installed in a power transmission tower on the ground or is buried underground for electromagnetic waves, land security, land use, etc.

In order to minimize the leakage of the transmitted electricity, most of these transmission lines are buried with a long length, but they are connected using a connecting device (connector) where connection is required.

As a prior art for connecting an underground transmission line, there is a “wire connection rod for an underground transmission line” of Korean Patent Publication No. 10-0945238, in which a transmission line with one end connected to an electrode is slidably coupled to a connection bar and attached to a spring. Since it is fixed to the slide block supported by The technique is disclosed.

However, in the conventional underground transmission line connector, when an excessive external force is applied, as the underground transmission line is disconnected (cut) at the part where the external force is applied, it is difficult to find the disconnected part.

Description of the connection operation, as shown in Fig. 8d, when the operator presses the button of the remote controller 700, the lock mechanism 500 is operated by this, and the string 410 of the original 400 is loosened. It will release the fixed state so that it can be released.

When the locking mechanism 500 is released as described above, the operator presses the button of the remote controller 700 to control the operation of the winch 400 so that the string 410 is released from the winch 400 .

When the string 410 is loosened to some extent, the operator opens the cover 120 and then enters the manhole 100 to release the external force (tensile force) applied to the first underground transmission line L1.

Then, the wire connection assembly 300 is opened, the first and second underground transmission lines L1 and L2 are electrically interconnected, and then the wire connection assembly 300 is touched, and then the indicator 223 of the connector 220 is It allows to be located in the center of the scale portion (211c).

When the connection work of the first and second underground transmission lines (L1, L2) is completed as described above, as shown in FIG. 8e, after closing the cover 120, the operator uses the remote controller 700 to winch 400 Wind the loosened string 410 by operating it until it is straightened out.

When the string 410 is wound around the winch 400 as described above, the operator operates the locking mechanism 500 using the remote controller 700 once again, and accordingly the string 410 is the locking mechanism 500 . is firmly fixed to

The present invention has the advantage of saving replacement cost and maintenance time due to forced disconnection (cutting) by allowing the connection part to be separated when external force (tensile force) is applied to the first and second underground transmission lines (L1, L2). have.

In addition, as the indicator 223 is moved together in the process of moving the connector 220 by the wire connection assembly 300 and is positioned on the scale portion 211c, the operator operates the wire connection assembly on the outside of the manhole 100. It is possible to intuitively recognize the current state, that is, the state in which the first and second underground transmission lines (L1, L2) are separated and the direction in which the external force acts, without trying to separate the 300 , and accordingly determine the maintenance plan quickly. There are advantages that can be

Furthermore, as the LED 620 of the notification mechanism 600 is lit by the line 410 when the connector 220 is moved, the operator can easily recognize the current state of the underground transmission line by looking at the lit LED 620, so that it can be maintained quickly It has the advantage of being able to repair.

Although the present invention has been described in detail only with respect to the specific embodiments described, it is natural for those skilled in the art that various changes and modifications can be made within the technical spirit of the present invention, and it is natural that such variations and modifications belong to the appended claims.
