Description

[0001] EQUIPMENT FOR GUIDING CABLE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary cable guide device for a marine substation, and more particularly, to a rotary cable guide device for a marine substation capable of safely protecting a power cable and a transmission cable at the seabed, .

Generally, a wind turbine (or an offshore wind farm) installed in the sea is installed so that it can withstand the wind from 50 to 100 meters in height, which is not a problem on the land.

The electric power generated through the wind turbine installed in the sea as described above is transmitted to the land by a marine substation installed near the wind turbine generator.

Such a marine substation transforms the power produced by the offshore wind farm and transfers it to the offshore substation (or land grid). Safety and reliability are important.

In such a marine substation, the power cable is drawn from the wind farm and the transmission cable is taken out to the ground substation.

At this time, when pulling in the power cable or pulling out the transmission cable, it is usually inserted into a pipe formed of a steel pipe and then guided to the seabed.

Then, the cable is bent and extended in the desired direction through the end of the pipe.

In this case, if the direction in which the cable is drawn or the direction in which the cable is drawn out is changed, the posture is corrected in a state where the cable itself is excessively bent.

Therefore, conventionally, there is a problem that the cable itself is damaged by forming the cable by physically breaking the direction.

An object of the present invention is to provide a rotary cable guide device for a marine substation that can safely protect a power cable from a wind power generation complex and a transmission cable to an onshore substation from the seabed and to freely adjust a guiding direction on the seabed.

In a preferred aspect, the present invention provides a pipe structure comprising: a guide pipe body fixed to a marine structure and into which a cable is inserted; A rotating pipe body rotatably installed at a lower end of the guide pipe body and inclined along a lower portion thereof to adjust a guiding direction of the cable; And a rotary part installed between the guide pipe body and the rotary pipe body for rotating the rotary pipe body.

The rotary pipe body is preferably bent at a lower end of the guide pipe body so as to have a predetermined curvature.

The rotary part includes a first flange installed at a lower end of the guide pipe body and having a plurality of first positioning holes formed along a circumferential direction, a plurality of first flanges provided at an upper end of the rotary pipe body, A second flange formed with two positioning holes and in close contact with the first flange, and a plurality of fastening means for fastening the first positioning holes and the second positioning holes.

Preferably, the first flange and the second flange are coupled to each other by a rail.

The rotating part includes a rotating body installed on the guide pipe body and rotating the rotating pipe body and a rotating body rotatably connected to the rotating body by controlling the rotating body according to a rotation angle set from the outside, Preferably, a controller is provided.

Preferably, the guide pipe body and the rotary pipe body are further provided with a plurality of boundaries in which a plurality of spaces are defined along the longitudinal direction so that different cables can be inserted.

The present invention has the effect of safely protecting the 33 kV power cable drawn from the wind power generation complex and the 154 kV transmission cable transmitting to the onshore substation.

In addition, the present invention has the effect of freely adjusting the guiding path of the cables by allowing the cable to be drawn in or drawn out regardless of the direction of the cable leading into the submarine substation inside the pipe body.

Further, the present invention has the effect of immediately controlling the rotational position at the bottom of the pipe body located at the seabed by electrically controlling the rotational position of the end of the pipe body at sea.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a cable guidance equipment for a marine substation of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a marine substation in which a cable guide facility of the present invention is installed, and FIG. 2 is a sectional view showing a cable guide facility of the present invention.

1 and 2, the cable guiding equipment of the present invention is fixedly installed on a marine substation installed on the sea.

The marine substation is installed on the sea so as to be positioned in the vicinity of the wind power generation complex placed on the sea.

The marine substation is composed of a lower structure 1 and a superstructure 2.

The lower structure 1 is a structure in which the lower end is fixed to the sea floor and the upper end is exposed to the sea. The lower structure 2 is composed of a plurality of support rods 10 and a boat land structure 11 is provided on the side of the support rods 10.

The upper structure 2 is a structure that is installed on the upper end of the lower structure 1 in a laminated manner, and power facilities for various purposes are installed in each layer.

The upper structure includes a cable deck 20, a sella deck 30, a main deck 40 and a roof deck 50, As shown in FIG.

The cable guiding apparatus of the present invention is installed so as to stand along the vertical direction to the support base 10 of the lower structure 1.

Referring to FIGS. 1 and 2, the cable guiding apparatus includes a guide pipe body 100, a rotary pipe body 200, and a rotary unit 300.

It is preferable that the guide pipe body 100 and the rotary pipe body 200 are formed of carbon steel pipes for pressure and have excellent strength.

The outer surfaces of the guide pipe body 100, the rotary part 300, and the rotary pipe body 200 can be prevented from being corroded by seawater through plating or another waterproof coating by electroplating.

Here, the guide pipe body 100 and the rotary pipe body 200 are formed in a hollow shape. A power or transmission cable 90 is inserted into the guide pipe body 100 and the rotary pipe body 200.

The guide pipe body 100 is fixed in a standing state on the supports 10 of the lower structure 2. As the fixing method, a fastening method such as a bolt, a nut or a clamp may be adopted.

Here, the upper end of the guide pipe body 100 is exposed to the sea, and the lower end is a portion located at the seabed.

The rotary pipe body 200 may be rotated in a horizontal direction at a lower end of the guide pipe body 100.

The rotary pipe body 200 may be formed to have a constant curvature.

The radius of curvature of the rotating pipe body 200 may be set within a range of 3 to 4 meters.

In the case of the rotary pipe body 200, since the curvature is formed at a portion substantially contacting the ground surface of the seabed, the guiding direction of the cable 90 is guided at the seabed ground surface, The impact can be absorbed and the damage can be effectively prevented.

The rotating part 300 according to the present invention determines the rotating pipe body 200 by adjusting the rotating direction at the lower end of the guide pipe body 100.

The rotation unit 300 includes a first flange 310, a second flange 320, and a fastening unit.

The first flange 310 is formed at the lower end of the guide pipe body 100. A plurality of first positioning holes 311 are formed in the first flange 310 along the circumferential direction.

The second flange 320 is formed at the upper end of the rotating pipe body 200. A plurality of second positioning holes 321 are formed in the second flange 320 along the circumferential direction.

The first and second flanges 310 and 320 are disposed in contact with each other.

The plurality of fastening means may be means consisting of a bolt 331 and a nut 332.

That is, the first and second flanges 310 and 320 can rotate with respect to each other before they are fastened. Accordingly, in a state in which the guide pipe body 100 is fixed, the rotating pipe body 200 can be rotated.

When the rotation is completed, the first and second positioning holes 311 and 321 are fastened using a plurality of fastening means, so that the first and second flanges 310 and 320 can be fixed.

Accordingly, the rotary pipe body 200 is fixed to the lower end of the guide pipe body 100 in a state in which the rotary pipe body 200 is completely rotated.

The rotating position of the rotating pipe body 200 can be adjusted in the above-described manner.

The operation of the cable guiding equipment of the present invention will be described with reference to the above configuration.

Referring to Figs. 1 to 3, first, the direction in which the power cable 90 is drawn in the seabed and the direction in which the power transmission cable 90 is drawn out are set.

Thus, the rotational position of the rotating pipe body 200 of each cable guiding facility is determined.

After the rotation position is determined as described above, each rotary pipe body 200 is rotated at the lower end of the guide pipe body 100 to fix the rotary position.

As described above, after the fastening state between the first and second positioning holes 311 and 321 is released, the rotational position of the second clamp 320 is changed by rotating the rotary pipe body 200, The rotational position of the body 200 can be variably adjusted.

After the rotation position is changed as described above, the rotation position of the guide pipe body 100 can be fixed again by fastening the first and second positioning holes 311 and 321 through the fastening means.

As described above, by rotating the rotary pipe body 200 according to the present invention along the pulling-in direction or the pulling-out direction of the cable 90, it is possible to solve the problem that the cable 90 is twisted or damaged .

In addition, since the rotary pipe body 200 according to the present invention is bent at a predetermined curvature, it is possible to easily absorb the impact when the bottom surface of the rotary pipe body 200 collides with the bottom surface of the sea floor There is also an advantage.

FIG. 4 is a view showing an example in which a boundary is formed in the cable guide facility of the present invention.

4, a guide pipe body 100 according to the present invention and a plurality of boundaries 110 dividing a space along a longitudinal direction thereof may be further formed in the hollow of the rotating pipe body 200 .

Thus, each cable 90 can be inserted into the spaces defined by the plurality of boundaries 110.

In addition, the boundary is formed to have a curvature so that frequent contact with the cable 90 can prevent the cable 90 from being damaged.

Due to this construction, when the power cable or the transmission cable 90 is formed in a large number, it can be inserted into the guide and rotary pipe bodies 100 and 200 without interference between the cables 90.

Also, although not shown in the drawings, the first clamp 310 and the second clamp 320 can be engaged with each other.

For example, a rail protrusion may be formed at a lower end of the first clamp 310 along a circumferential direction, and a rail groove may be formed at an upper end of the second clamp 320 to which the rail protrusion is rail-coupled.

Accordingly, there is an advantage that the rotating pipe body 200 can be stably rotated while preventing the first and second clamps 310 and 320 from being separated from each other when the rotating pipe body 200 is rotated.

5 is a view showing another example of the rotating part according to the present invention.

5, the rotating pipe body 200 according to the present invention can be rotated to have a rotation angle set by the rotation unit 400. [

The rotation unit 400 is installed in the guide pipe body 100 and includes a rotating unit 410 for rotating the rotating pipe body 200 and a rotating unit 410 electrically connected to the rotating unit 410, And a controller 420 for controlling the rotator 410 to rotate the rotating pipe body 200.

The controller 420 is electrically connected to the setting unit 430. The setter 430 may set the rotation position or the rotation angle of the rotary pipe body 200 and input the rotation position or the rotation angle to the controller 420.

When the input is completed, the controller 420 controls the driving of the rotator 410 to rotate the rotating pipe body 200 to a desired rotational position or rotational angle.

Here, the rotator 410 may be a device such as a rotating motor, and may be a device installed at an end of the guide pipe body 100 to rotate the rotating pipe body 200.

Of course, since the rotator 410 is located at the seabed, it is preferable to use a waterproof motor.

The implementation according to the present invention with the above configuration can safely protect the 33 kV power cable coming in from the wind farm and the 154 kV transmission cable from the submarine.

In addition, the embodiment of the present invention can freely adjust the guide path of the cables by allowing the cable to be drawn in or pulled out, irrespective of the direction of the cable leading into the marine substation inside the pipe body.

Further, the embodiment according to the present invention can instantly adjust the rotational position at the bottom of the pipe body located at the seabed by electrically controlling the rotational position of the end of the pipe body at sea.

Although the present invention has been described with respect to specific embodiments of a rotary cable guide facility for a maritime substation of the present invention, it is apparent that various modifications can be made without departing from the scope of the present invention.

Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be determined by the scope of the appended claims and equivalents thereof.

It is to be understood that the foregoing embodiments are illustrative and not restrictive in all respects and that the scope of the present invention is indicated by the appended claims rather than the foregoing description, It is intended that all changes and modifications derived from the equivalent concept be included within the scope of the present invention.
