Description

Variable J-Tube < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a J-tube which is installed in a marine platform and protects an internal cable, and is constructed to be installed with a different length depending on the height of the sea surface.

As the offshore wind farms become larger and diversified, the range of offshore wind turbines is getting wider. As the installation range of the offshore wind turbine increases, the height of the seawater in the installed area also becomes different, and the tower height of the offshore wind turbine varies proportionally with the height of the seawater.

On the other hand, offshore wind power generators extend the off-shore cables to offshore wind power generators in order to transmit the generated power onshore. The cable extends along the bottom surface of the sea and has a problem of being bent perpendicularly along the tower of the offshore wind power generator in the vicinity of the tower of the offshore wind power generator.

The J tube protects the cable that is bent vertically along the tower of the offshore wind power generator and is designed to easily raise the cable located on the bottom of the sea to the tower of the offshore wind power generator.

1 is a conceptual view showing a state in which a conventional J tube is mounted on a tower of an offshore wind power generator, and FIG. 2 is a detailed view of the J tube shown in FIG.

1 and 2, the J tube 20 is divided into a vertical part 21 vertically positioned along the tower 1 and a curved part 22 formed at the lower end of the vertical part 21 . The upper end of the vertical portion 21 is fixed to the marine platform 3 of the tower 1 and the lower end of the curved portion 22 is located in contact with the bottom surface of the sea. The cable 7 extending from the onshore substation 5 extends along the bottom surface of the sea toward the offshore wind turbine 9 and enters the inside of the curved portion 22 of the J tube 20, 21 extending upwardly and the cable 7 leading to the marine platform 3 extends to the generator 8 installed at the upper end of the tower 1.

This J tube 20 not only protects the cable 7 located in the seawater but also protects the cable 7 from the bend of the J tube 20 when the cable 7 is pulled up from the marine platform 3 at the time of installation of the cable 7 22 are positioned toward the land side, so that the cable 7 can be easily pulled up.

However, as the installation area of the offshore wind turbine generator 9 is widened, the area where the offshore wind turbine generator 9 is installed is varied, and accordingly, the length of the J tube 20 also changes. However, since the conventional J tube has a constant length, it is inconvenient to individually manufacture the J tube according to the height of the sea water in which the offshore wind power generator is installed.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the prior art as described above, and it is an object of the present invention to provide a variable-type J tube which can change the length according to the height of seawater.

According to an aspect of the present invention, there is provided a J-tube including a vertical part positioned in a longitudinal direction of a tower and a curved part positioned toward a direction in which a cable enters from a lower end of the vertical part, The upper unit and the lower unit are divided into an upper unit and a lower unit located at the upper portion and the lower unit, respectively. What is possible is a technical feature.

According to a preferred embodiment of the present invention, the upper unit and the lower unit are respectively fitted with fixing clamps which can be fixed to the tower.

According to a preferred embodiment of the present invention, the upper end of the lower unit is expanded, the lower end of the upper unit is inserted and overlapped with the expanded upper end of the lower unit, and the lower end of the upper unit is bent outward, And the upper end of the lower unit is bent inwardly to form a latching jaw to prevent the upper unit and the lower unit from being separated from each other.

According to a preferred embodiment of the present invention, a protection member is fixed to the lower end of the upper unit to protect a cable located inside the J tube.

Further, according to a preferred embodiment of the present invention, the upper end of the upper unit is fixed to an offshore platform formed on the tower.

As described above, the J tube of the present invention is advantageous in that it can be easily installed because the length can be changed according to the height of the seawater.

In addition, the J-tube of the present invention is structured such that the cable can not be damaged by securing a portion where the cable is inevitably damaged according to the variable structure. Therefore, it can be easily installed without damaging the cable.

FIG. 5 is a conceptual diagram showing a state where the J-tube according to the present invention is installed in a sea water-based wind turbine installed at a thin water depth and an offshore wind turbine installed at a deep water depth.

The preferred embodiments of the J-tube according to the present invention will now be described in detail with reference to the accompanying drawings.

3 is a side cross-sectional view of the J tube shown in Fig. 3, and Fig. 5 is a cross-sectional view of the offshore wind turbine installed at a thin water depth using the J tube according to the present invention. And an offshore wind turbine installed at a deep water depth.

As shown in FIG. 3, the J tube 100 is overlapped such that the upper unit 130 and the lower unit 140 of the cut part in the middle of the length of the vertical part 110 are overlapped with each other. The entire length of the J tube 100 is expanded and contracted as the upper unit 130 is inserted into the lower unit 140 or upward.

The J tube thus constructed will be described in detail below.

The J tube 100 includes a vertical part 110 positioned in the longitudinal direction of the tower 1 and a curved part 120 curved in the land direction at the lower end of the vertical part 110. Particularly, the middle of the vertical part 110 is cut, and the upper part of the overlapped part is referred to as an 'upper unit 130', and the lower part of the overlapping part is cut into the 'lower unit 140' Quot;

More specifically, the vertical part 110 is divided into an upper unit 130 and a lower unit 140, and a curved part 120 is formed at a lower end of the lower unit 140. The first fixing clamp 151 is mounted on the upper unit 130 and the second fixing clamp 152 is mounted on the lower unit 140. The first fixing clamp 151 and the second fixing clamp 152, Is fixed to the tower (1).
