BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wind turbine installation structure, and more particularly, to a wind turbine installation structure capable of realizing rapid installation of a tower structure and improving the efficiency of equipment operation such as installation ship.

When a structure such as a wind turbine is installed on the sea, the structure constructed on the land is loaded on the installation vessel and moved to the working position of the sea.

The installation ship arriving at the sea installation position performs the installation work by using the crane while lifting the hull from the sea by lowering the leg of the jacking system to the sea floor. In this way, the hull can be stably installed without being affected by waves.

When installing the wind turbine, lift the parts of the wind turbine loaded on the installation vessel with a crane and install it on the foundation structure pre-installed on the sea. That is, the tower structure of the wind turbine is installed first on the foundation structure of the sea, and then the nacelle and the blade are sequentially installed. Of course, when installing wind turbines prefabricated on the ground, the entire wind turbine assembled is lifted by a crane and installed on the foundation structure.

In this case, the parts of the wind turbine or the assembled wind turbine are lifted up by the crane and placed on the foundation structure, and the operator tightens the bolts to connect the foundation structure with the parts (tower structure, etc.) of the wind turbine.

However, this type of installation requires the use of the crane of the ship during construction (bolt fastening) at sea, and it is necessary to hold the parts such as the tower structure and the assembled wind turbine for a long time so that the work efficiency is low. there was. In other words, the installation ship has to install one wind turbine and move to another work area. There is a problem that the crane of the installation ship must be used until one installation work is completed.

As shown in the figure, a wind turbine 10 installed on the sea includes a tower structure 11, a nacelle 12 rotatably installed on the tower structure 11 and incorporating a generator and the like, And a blade (13) for rotating the generator in the nacelle (12).

In order to install the wind turbine 10 on the sea, the foundation structure 20 fixed to the seabed is first installed and the tower connection portion 30 is installed on the foundation structure 20 so as to be positioned above the water surface. Then, the parts of the wind turbine are sequentially installed from the tower structure 11 on the tower connection part 30. [ Or the wind turbine 10 preliminarily assembled on the land can be installed in such a manner that the whole of the wind turbine 10 is carried to an installation area where the foundation structure 20 is installed and the lower end of the tower structure 11 is connected to the tower connection part 30.

Figs. 2 to 5 show examples of installation structures for quickly installing the tower structure 11 in the tower connection portion 30 in the installation process of the wind turbine 10. Fig.

2 and 3, the tower connection part 30 installed on the foundation structure 20 accommodates the lower end of the tower structure 11 so that the lower end of the tower structure 11 can enter and join from the upper part thereof And a support groove 31 for supporting the lower end surface of the tower structure 11.

The support groove 31 has an inner diameter corresponding to the outer diameter of the tower structure 11 and has a predetermined depth in the vertical direction to receive and support the lower end of the tower structure 11. The lower end of the support groove 31 is provided with a stepped support surface 32 for supporting the load of the wind turbine 10 so that the lower end of the tower structure 11, which has entered into the inside thereof, is hooked.

A plurality of coupling guide grooves 33 are formed on the inner surface of the support groove 31 in the vertical direction so as to guide the coupling of the tower structure 11 and a plurality of coupling grooves 33 are formed on the lower end of the tower structure 11, A plurality of engaging guide protrusions 15 are provided so as to be able to engage correspondingly to the guide grooves 33. Here, a case where a plurality of coupling guide grooves 33 and a plurality of coupling guide protrusions 15 are provided, however, the number of the coupling guide grooves 33 and the coupling guide protrusions 15 may be one or more.

2 and 4, the coupling guide groove 33 is formed in a recessed shape on the inner surface of the support groove 31 and extends in the vertical direction from the upper end of the support groove 31 to the support surface 32 . The engagement guide groove 33 is formed in a spiral shape from the upper end of the support groove 31 to the support surface 32 and has an entry guide portion 33a for guiding the entrance of the engagement guide projection 15, And a binding guide portion 33b extending from the lower end in the circumferential direction of the inner surface of the support groove 31 by a predetermined length.

The entrance guide portion 33a guides the rotation of the tower structure 11 to improve the stability of the connection and at the same time guides the tower structure 11 to be coupled to the correct position. The binding guide portion 33b allows the coupling guide projection 15 to be hooked by slightly rotating the tower structure 11 in a state where the coupling guide projection 15 enters the lower end of the entrance guide portion 33a, Thereby allowing the tower structure 11 to be securely fastened to the tower connection 30.

The coupling guide protrusion 15 protrudes outward from the peripheral surface of the lower end of the tower structure 11 and has a curved surface guide portion 15a provided at a lower portion in a curved shape so as to smoothly enter the coupling guide groove 33 Respectively.

The lower end of the curved surface guide portion 15a of the coupling guide projection 15 may be provided so as to protrude further downward than the lower end of the tower structure 11 as shown in FIG. 2 and 5, at the time when the coupling of the tower structure 11 is completed, the coupling guide groove 33b of the coupling guide groove 33 is formed with the curved surface guide portion 15a of the coupling guide projection 15 A lower end can be engaged with and caught by a catching groove 34 at a lower portion thereof.

[

2 and 4, the installation structure of the present embodiment includes at least one fastening member 41 for fastening the tower structure 11 to the tower connection portion 30 so as to maintain a more rigid connection therebetween . The fastening member 41 may be formed of a bolt or the like and may be provided on the inner side of the tower connecting portion 30 in a state where the fastening member 41 is installed to penetrate from the outer surface of the tower connecting portion 30 through the tower connecting portion 30 and the lower portion of the tower structure 11. [ And the nut 41 may be fastened and fixed.

Next, a method of installing the wind turbine 10 having the installation structure according to the present embodiment will be described.

6, when the wind turbine 10 is installed, the tower structure 11 previously assembled on the ground or the ship 100 is lifted by using the crane 110, And may be installed in such a manner as to enter the inside of the tower connecting portion 30 on the upper portion of the structure 20. At this time, the tower structure 11 is lowered with the position of the coupling guide projection 15 at the lower portion of the tower structure 11 aligned with the coupling guide groove 33 of the tower connection portion 30.

4 and 5, the coupling guide protrusion 15 is guided along the helical coupling guide groove 33 and descends, so that the lower end of the tower structure 11 can be accurately guided to the assembling position. The joining guide protrusion 15 reaches the lower end of the joining guide portion 33a of the joining guide groove 33 and the tower structure 11 is rotated a little further, So that a stable installation can be achieved. At this time, since the lower end of the curved surface guide portion 15a of the coupling guide projection 15 enters the locking groove 34, a more rigid coupling can be achieved.

The installation structure of the present embodiment allows the lower portion of the tower structure 11 to enter the support groove 31 of the tower connection portion 30 and to maintain the supported state, and the coupling guide groove 33 and the coupling guide projection 15, The fastening of the tower structure 11 can be realized only by the action of lowering the tower structure 11 to the crane 110. [ In this state, the tower structure 11 does not fall even when the crane 110 is removed.

In addition, after the tower structure 11 is installed, since the crane 110 can be separated from the tower structure 11 and moved for another operation (preparation for nacelle installation), the operation efficiency of the equipment can be increased. While the crane 110 prepares for another work, the worker can quickly perform the installation work by performing subsequent work such as fastening the fastening member 40. [

7, when the wind turbine 10 is transported to the installation vessel 110 in a state that the wind turbine 10 is fully assembled on the land, the wind turbine 10 assembled with the crane 110 is lifted up A basic installation can be performed only by lowering the lower portion of the tower structure 11 to the tower connecting portion 30. [ Therefore, the installation ship 100 can separate the crane 110 in this state and move for other operations, thereby improving the operation efficiency of the equipment. The operator can finish the installation work by separating the cranes 110 and then fastening the fastening members 40 to the tower connection part 30 and the tower structure 11 to further secure them.

Here, the case where the installation structure of this embodiment is applied to a wind turbine installed in the sea has been described, but such installation structure can also be applied to a case where a wind turbine is installed on the land.
