Technology Field

Background Technology

[0002] Generally, in Seoul and urban areas, numerous power and communication lines are installed by burying them underground, and due to space and construction constraints, many shared conduits are used for both lines.

[0003] In other words, the underground overhead line facility is installed inside a power conduit buried at a certain depth from the surface, and by installing a communication conduit inside the power conduit, power lines are installed in the remaining space excluding the space occupied by the communication conduit inside the power conduit, and communication lines are installed inside the communication conduit, thereby allowing power lines and communication lines to be installed simultaneously.

[0004] However, the underground burial of communication conduits installed inside power conduits has reached saturation in urban areas. If power and communication lines are installed in separate conduits, it leads to constraints due to insufficient installation space, excessive costs resulting from repeated excavation and restoration of the same sections, and causes problems such as inconvenience to residents.

[0026] That is, the left clamp (100) and the right clamp (200) include a pair of large radius curved sections (110) (210) and a pair of small radius curved sections (120) (220) formed symmetrically to clamp the power waveform tube (10) from the lower left and right sides and to clamp the communication inner tube (20) from the upper left and right sides.

[0027] At this time, the above pair of large radius curved surfaces (110) (210) serve to clamp the outer surface of one side of the groove of the power waveform tube (10) at the bottom so as to wrap it in half from the left and right sides, and are formed by including a pair of hinge holes (112) (212), a pair of stepped surfaces (114) (214), and a pair of rotation-preventing surfaces (116) (216).

[0028] The above pair of hinge holes (112)(212) are each formed on the stepped surface portions (114)(214), and serve to be simultaneously joined by a hinge (300) on the stepped surface portions (114)(214) that overlap with the lower end of the large radius curved surface portions (110)(210).

[0029] A pair of rotation-preventing surfaces (116) (216) are formed on the lower part of the large radius curved surface (110) (210), and serve to prevent rotation so that the gap between the lower part of the left clamp (100) and the right clamp (200) does not widen when the left clamp (100) and the right clamp (200) are simultaneously clamped from the left and right sides and then placed on the ground.

[0030] The above pair of small radius curved sections (120)(220) are on the upper A pair of round-shaped parts (122) (222) are formed at the top to serve the function of clamping the outer surface of one side of the communication tube (20) so as to wrap it in half from the left and right sides.

[0031] At this time, it is preferable that the gap between the pair of small radius curved sections (120 (220)) be formed to be smaller than the diameter of the communication inner tube (20) when the gap between the left clamp (100) and the right clamp (200) is narrowed to the maximum.

[0032] The above pair of rounded sections (122) (222) serve to guide the communication tube (20) to open up with minimized friction when the tube is pressed into the gap between the small radius curved sections (120 (220)) from the outside of the left clamp (100) and the right clamp (200).

[0033] A fixing hole (130) is formed in the front and rear portions between the left large radius curved portion (110) and the left small radius curved portion (120) such that one side of the connecting member (400) is rotatably inserted and fixed.

[0034] A catch groove (230) is formed on the right side between the right large radius curved section (210) and the right small radius curved section (220) so that the other side of the connecting member (400) is caught, and a pair of catch protrusions (240) with open tops are formed on the front and rear sides between the right large radius curved section (210) and the right small radius curved section (220) so that the connecting member (400) is press-fitted and fixed.

[0035] The hinge (300) serves to connect the lower part of the left clamp (100) and the lower part of the right clamp (200), and is preferably formed with a rivet and eyelet connection structure.

[0036] The above connecting member (400) is connected to pass between the upper part of the left clamp (100) and the upper part of the right clamp (200) to pass between the power waveform tube (10) and the communication inner tube (20), and serves to block the entrance of the large radius curved section (110) (210) while opening the entrance of the small radius curved section (120) (220). It comprises a rectangular ring-shaped body (410), a pair of front and rear fixed ends (420a) (420b), a catch bar (430), and a handle part (440).

[0037] At this time, the above-mentioned pair of front and rear fixed ends (420a) (420b) are integrally formed on one end of the body (410) and serve to be rotatably inserted and fixed into the fixed hole (130).

[0038] The above-mentioned catch bar (430) is integrally formed on the other side of the body (410) and serves to be detachably attached to the catch groove (230).

[0039] The handle portion (440) is integrally formed on one side of the catch bar (230) and serves to pull the connecting member (400).

[0040] It is preferable that the above connecting member (400) be made of a material capable of elasticity in the direction in which the left clamp (100) and the right clamp (200) spread apart.

[0041] In addition, the connecting member (400) is preferably made of a material having an elastic force greater than a certain amount so as to be able to open and close the upper part of the left clamp (100) and the upper part of the right clamp (200) and pull by elasticity.

The method comprises the step of inserting a communication tube (20) into the interior of a pair of small radius curved sections (120) (220) through the upper portion between the left clamp (100) and the right clamp (200).

[0043] At this time, when the communication inner tube (20) is pressed in, the gap between a pair of small radius curved sections (120) (220) is widened by the elasticity of the connecting member (400) and then narrowed after the communication inner tube (20) passes through.

[0044] As such, the communication inner tube coupling device and method for the power waveform tube of the present invention has the advantage of being able to quickly and accurately attach the communication inner tube (20) by simply operating the left clamp (100) and the right clamp (200), which are connected to the outside of the power waveform tube (10) so as to be rotatable via a hinge (300) and connected to the upper part so as to be detachably attached using a connecting member (400), without deforming the existing power waveform tube (10) and the communication inner tube (20), thereby eliminating the complex process of installing power lines and communication lines in different conduits, and minimizing the costs incurred during excavation and restoration, as well as minimizing inconvenience to residents.
