BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a ground-only underground distribution line fixture for receiving an underground cable embedded in the ground to protect the underground cable from external interference safely.

Generally, in order to supply electric power to a residential area or an industrial complex, a pipe is buried in the ground and the electric wire is laid in the inside thereof. This minimizes the exposure to the underground wire, thereby preventing the breakage of the underground wire from external interference This is why they are buried in the earth.

However, in the case of a pipe which is buried in the ground and in which an underground wire is received, if the outer surface is corroded by storm or sewage after a certain period of time, or when self-breakage occurs due to various external factors, Repair and replacement works are performed through excavation to expose the pipe to the outside.

In the excavation work, a pipe embedded in the ground can be quickly and easily taken out to the outside by using a conventional excavator (fork-lift). At this time, when the bucket of the excavator (shovel shovel) There is a problem that cracks are generated in the pipe by striking the outer surface of the pipe. Moreover, when the operator does not know the buried position accurately, the pipe is frequently broken by the bucket.

Therefore, even if the operator is not clearly aware of the buried position, means is required to promptly inform the position of the pipe buried in the ground.

In addition, a study on a solution to such a problem has been carried out in which, due to penetration of rainwater or underground water between pipes and pipes installed successively, It is actively proceeding.

The switch unit 80 is a conventional limit switch, and the outer line 60 is an external interference, that is, (Not specifically shown) that is vertically projected by the movable piece 62 when rotated by the movable piece 62 is turned around the axis and the operation is turned on / off .

Accordingly, when the switch unit 80 is turned on, the operation signal is inputted to the control unit 90. The control unit 90 receives the operation signal and outputs the emergency signal to the speaker unit 100 At this time, the speaker unit 100 generates a warning sound so that the operator can recognize the excavation work.

The power supply unit 110 is a power supply source and supplies power so that the switch unit 80, the control unit 90, and the speaker unit 100 can be easily driven.

The charging terminal 120 is securely protected from the earth and sand by the protective cap 130 hingedly hinged to the outer surface of the inner pipe 10 as shown in FIG.

Particularly, the charging terminal 120 is electrically connected to the power supply unit 110 so that even if the power of the power supply unit 110 is exhausted due to the generation of the sound of the speaker unit 100 according to the operation of the switch unit 80, The connection terminal 200 to which the external power is supplied is connected to the terminal 120 for charging the power supply unit 110, so that the power supply unit 110 can be used semi-permanently.

In addition, though not specifically shown, a rubber packing is attached to the bottom surface of the protection cap 130 to be connected to the inner pipe 10, thereby preventing the penetration of the excellent and groundwater into the inside of the protection cap 130 And the material of the protection cap 130 is preferably formed of a metal material and a synthetic resin material having sufficient strength to withstand earth pressure.

Hereinafter, the operation of the present invention will be described.

As shown in FIG. 4A, the insertion groove 31 formed in the sealing material accommodating portion 30 of the inner tube in the longitudinal direction of the inner tube 10 in the ground, and the striking portion 20 'of the inner tube 10' 'So that the first flange 40 and the second flange 70' formed on each of the inner tubes 10 and 10 'can be connected to each other.

The sealant SC filled in the insertion groove 31 by the striking portion 20 'of the insulating tube 10' inserted into the insertion groove 31 as described above is inserted into the striking portion 20 ' So that the second thin film 35 is torn and drawn out to the outside through the outflow hole 33. As shown in FIG.

The drawn sealant SC flows into the space between the first flange 40 and the second flange 70 'that are connected to each other and is applied to the connection surface, and when a predetermined time elapses, the sealant SC is cured and bonded to each other.

Therefore, the sealing agent SC drawn by the striking portion 20 'flows between the first flange 40 and the second flange 70' of each of the inner tubes 10, 10 'which are continuously installed, It is possible not only to prevent leakage of leaking water to the inside but also to strengthen the bonding force between the inner pipe 10 and the inner pipe 10 'and to maintain the airtight condition at all times, so that the underground wire (L) So that it can be safely protected.

After the inner pipe 10 is installed as described above, the bolts are loaded into the mounting holes (not specifically shown) formed in the first flange 40 and the second flange 70 ' Then, it may be continuously applied in the same manner as described above.

When the underground distribution cable fixing board for exclusive use of the submerged power distribution line is aged or corroded and maintained or repaired after a certain period of time has elapsed as described above, the excavation work is performed using the excavator. At this time, Knowing only the approximate location of the underground distribution line fixture, you will dig the ground with a bucket.

When the outer surface of the outer tube 60 rotatably installed on the outer surface of the inner tube 10 is scratched up when the bucket of the excavator digs the ground and enters the inside of the excavator as described above, And the movable piece 62 protruding along the inner circumferential surface of the outer tube 60 at this time rotates the operating piece (not specifically shown) of the switch unit 80 provided in the inner tube 10. [

Therefore, when the operation of the switch unit 80 turned on by the movable piece 62 is turned on and the operation of the switch unit 80 is turned on, the operation signal is inputted to the control unit 90 The control unit 90 receives the operation signal, outputs the emergency signal, and transmits the emergency signal to the speaker unit 100.

In the speaker unit 100 receiving the emergency signal as described above, a strong beep is generated to easily recognize the operator during the excavation work, thereby protecting the inner pipe 10 buried in the ground. .

When the power of the power source unit 110 is completely consumed by the operation of the speaker unit 100, the protection cap 130, which covers and protects the charging terminal 120, The connection terminal 200 to which the external power is supplied is connected to the charging terminal 120 electrically connected to the power supply unit 110 to charge the power supply unit 110 again, And can be used semi-permanently, as shown in FIG. 4C.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. .
