Description

{PROTECTION APPARATUS FOR APARTMENT UNDERGROUND TRANSMISSION LINE}

More particularly, the present invention relates to an apparatus for protecting an underground power cable, and more particularly, it relates to an apparatus for protecting a cable in an underground power cable, and more particularly, The present invention relates to a power cable protection device for a residential subway underground which can be smoothly maintained.

Generally, in an urban area or a large-scale apartment complex, there is installed a drainage pipe for the installation and management of electric wires such as high-voltage line, low-voltage line, and communication cable together with a water supply and sewage pipe. And electric wires and communication cables for supplying electricity are supplied to supply electricity and the like to each home or office.

Since the buried pipe is buried in the ground to prevent exposure to the outside, it is buried in the ground, so that the wire or the communication cable is not exposed to the outside, so that the buried pipe is not damaged, The communication cable is prevented from being damaged.

In other words, electricity used in each home, office, and large-scale factory is supplied through a substation installed in each region. Such a substation transforms the voltage or current and distributes the electric power. Or the distribution line to the user.

The substation is usually installed on the ground. In such a substation, the high-voltage electric current must be transferred. Most of the high-voltage electric wires are exposed to the outside. The high-voltage electric wires exposed to the outside are short- It is easy to induce, and due to the harshly constructed high-voltage electric wire, there is a problem such as hatching the surrounding scenery, and the high voltage electric wire is installed in the underground.

When a high-tension wire is installed in the underground, the buried pipe for laying the wire is buried in the ground to prevent the high-tension wire from being exposed to the outside, thereby solving the problems caused by the external interference and the surrounding landscape .

However, since the buried pipe embedded in the ground is difficult to be visually recognized from the outside, for example, when digging the earth with an excavator for road construction, the buried pipe embedded with the bucket of the excavator is hammered, And various cables and electric wires installed inside the buried pipe are damaged, causing problems such as communication disconnection or short circuit.

In addition, when the buried pipe is a gas supply pipe, the gas is directly exposed from the gas supply pipe damaged by the excavator, and the buried pipe is exposed to a serious accident risk.

A prior art related to the present invention is Korean Patent No. 10-10327110000 (Apr. 26, 2011).

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an apartment underground power cable protection system according to the present invention will be described with reference to the accompanying drawings.

Fig. 1 is a view showing the construction of an apartment underground power cable protection apparatus according to the present invention.

Referring to FIG. 1, the apparatus for protecting underground power cables in a housing of the present invention comprises a support frame 100 embedded in the ground, a cable 10 disposed inside the support frame 100, The protection case 200 includes a protection case 200 buried in the ground and a lifting part 300 lifting the protection case 200. The protection case 200 is exposed to the outside, And a control unit 500 for raising the protection case 200 and positioning the protection case 200 on the ground.

Although not shown in the drawings, both ends of the support frame 100 are connected by respective elevating devices.

Each of the elevating devices has an axis to be elevated, and each axis is connected to both ends of the supporting frame.

The support frame is provided with a sensor for detecting the horizontal position.

The sensor transmits a signal indicating whether the sensor is horizontal or not to the controller 500.
