Description

Technical Field

[0001] This invention relates to the field of support technology, specifically to a stabilizing support for offshore wind turbines. Background Technology

[0002] Because winds at sea are generally stronger than those on land, offshore wind power generation devices require greater stability. Therefore, brackets are installed on wind turbines to increase their stability.

[0003] In the prior art, the support structure uses a ring plate fixed to the outside of the wind turbine, with steel cables installed on the ring plate. The steel cables are then pulled and fixedly connected to the offshore platform, thus securing the wind turbine. However, due to the height of the wind turbine, the installation of the ring plate requires construction workers to climb to a high place, which is troublesome and dangerous. Therefore, this application provides a stable support structure for offshore wind turbines to improve the problem. Summary of the Invention

[0004] The purpose of this invention is to provide a stable support for offshore wind turbines to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a stabilizing support for an offshore wind turbine, comprising:

[0006] Pre-assembled components are installed on the wind turbine piles;

[0007] The fastener is used to slide on the wind turbine pile. When the fastener slides to connect with the pre-installed component, the sliding of the fastener is restricted. The fastener is used to connect the wind turbine pile to the wind turbine mounting platform.

[0008] The lifting component, which is connected to the fixing component, is located on the wind turbine mounting platform and is used to drive the fixing component to slide on the wind turbine pile.

[0037] Example 1

[0038] Please see Figure 1-6 This invention provides a technical solution: a stabilizing support for an offshore wind turbine, comprising:

[0039] Pre-installed component 1 is installed on the wind turbine pile. When installing the wind turbine, pre-installed component 1 is installed on the wind turbine pile in advance.

[0040] The fixing component 2 is used to slide on the wind turbine pile. When the fixing component 2 slides to connect with the pre-installed component 1, the sliding of the fixing component 2 is restricted. The fixing component 2 is used to connect the wind turbine pile to the wind turbine installation platform. In use, when the fixing component 2 slides on the pile, when the fixing component 2 slides to connect with the pre-installed component 1, the sliding of the fixing component 2 is restricted by the pre-installed component 1. Thus, the pile is connected to the platform through the fixing component 2, which increases the stability of the wind turbine in use.

[0041] Lifting component 3 is connected to fixing component 2. Lifting component 3 is located on the wind turbine installation platform. Lifting component 3 is used to drive fixing component 2 to slide on the wind turbine pile. When in use, lifting component 3 is located on the platform, so that construction personnel can drive fixing component 2 from the platform. When installing fixing component 2, construction personnel do not need to climb, which facilitates the installation of fixing component 2 and increases the safety of construction personnel during installation.

[0042] Compared with existing technologies, this method first pre-installs the pre-assembled component 1 on the wind turbine pile, and then lifts the fixing component 2 with the assistance of the lifting component 3, so that the fixing component 2 moves to a designated height on the wind turbine pile. The wind turbine pile is then fixedly connected to the wind turbine installation platform through the fixing component 2, which increases the stability of the wind turbine pile during use. When installing the fixing component 2, the lifting component 3 allows construction personnel to install the fixing component 2 without climbing, making the installation of the fixing component 2 easier and increasing the convenience of the device installation.

[0043] like Figure 2 As shown, in some embodiments, the fastener 2 includes:

[0044] A ring plate 201 is fitted onto the wind turbine pile. Steel cables 202 are installed around the perimeter of the ring plate 201, with the free ends of the cables connected to the wind turbine mounting platform. The ring plate 201 is connected to the lifting component 3. The ring plate 201 comprises two plates connected by bolts. Figure 2 As shown, this facilitates the installation of the ring plate 201 on the pile. During use, the ring plate 201 is lifted to a certain height by the lifting component 3, as shown... Figure 1 As shown, the steel cable 202 is then connected to the platform. The connection between the steel cable 202 and the platform can be achieved by bolt connection or anchoring. In use, the tension of the steel cable 202 increases the stability of the wind turbine pile during use.

[0045] A sliding block 203 is slidably mounted on a ring plate 201. A socket 204 is provided on the pre-assembled part 1. A rod 205 for insertion into the socket 204 is mounted on the sliding block 203. A connecting spring 7 is installed between the sliding block 203 and the ring plate 201. Figure 1 From the main perspective, the sliding block 203 is slidably mounted on the ring plate 201 in the horizontal direction. When the ring plate 201 slides, the insertion rod 205 is abutted by the side wall of the pile, causing the connecting spring 7 to be in a stretched state. When the insertion rod 205 moves to the insertion hole 204, the connecting spring 7 pushes the insertion rod 205, causing it to be inserted into the insertion hole 204. The inner wall of the insertion hole 204 blocks the outer wall of the insertion rod 205, thus restricting the sliding of the ring plate 201. This allows the steel cable 202 to connect the pile to the platform, increasing the stability of the wind turbine pile during use.

[0046] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, a base plate 4 is mounted on the sliding block 203, a side plate 5 is mounted on the ring plate 201, a slider 6 that slides with the side plate 5 is mounted on the base plate 4, a connecting spring 7 is installed between the side plate 5 and the base plate 4, and a channel for accommodating the slider 6 is provided on the side plate 5, such as... Figure 3As shown, the inner wall of the channel restricts the side wall of the slider 6, so that when the slider 203 slides, the base plate 4 can only slide in a straight line in the horizontal direction, which increases the stability of the slider 203 when sliding, and also increases the stability of the connecting spring 7 when deforming.

[0047] like Figure 3 and Figure 6 As shown, in some embodiments, the lifting member 3 includes:

[0048] A fixed plate 301 is installed on the wind turbine mounting platform. A winding roller 302 is rotatably mounted on the fixed plate 301. A cable 303 is installed on the winding roller 302. The free end of the cable 303 is connected to the ring plate 201. In use, by rotating the winding roller 302, the cable 303 pulls the ring plate 201 to slide on the pile, so that the ring plate 201 gradually approaches the pre-installed part 1. The cable 303 and the steel cable 202 are made of the same material, which are both lifting steel wire ropes.

[0049] The guide wheel 304 is installed on the pre-assembled part 1. The guide wheel 304 is used to support the cable 303. During use, the guide wheel 304 guides the cable 303, making the cable 303 more stable during movement and increasing the stability of the cable 303 during movement.

[0050] like Figure 6 As shown, in some embodiments, an extension plate 8 is installed on the take-up roller 302. The diameter of the extension plate 8 is larger than the diameter of the take-up roller 302. A handle 9 is installed on the extension plate 8. In use, the extension plate 8 increases the lever arm of the take-up roller 302 when it rotates, which makes it easier to rotate the take-up roller 302. The construction personnel can rotate the extension plate 8 through the handle 9, which increases the practicality of the device.

[0051] like Figure 1 As shown, in some embodiments, a connecting rope 10 is installed on the base plate 4. The connecting rope 10 is connected to the cable 303. When the cable 303 is wound up to the maximum extent, the connecting rope 10 is also taut, so that the base plate 4 is pulled to abut against the side plate 5, thereby restricting the sliding of the base plate 4 and the sliding block 203 and increasing the stability of the sliding block 203 during use.

[0052] like Figure 3 and Figure 4 As shown, in some embodiments, the pre-assembled component 1 includes:

[0053] Pre-installed plate 101 is installed on the wind turbine pile, and insertion hole 204 is opened on the pre-installed plate 101. The pre-installed plate 101 is installed on the pile by bolts.

[0054] The pre-installed block 102 is installed on the wind turbine pile. The ring plate 201 has a guide groove 103 for accommodating the pre-installed block 102. The pre-installed block 102 is also installed on the pile by bolts. When installing the ring plate 201, the guide groove 103 is aligned with the pre-installed block 102 so that when the insertion rod 205 moves to the pre-installed plate 101, the insertion rod 205 can be aligned with the insertion hole 204, which increases the practicality of the device.

[0055] like Figure 5 As shown, in some embodiments, the end face of the insertion rod 205 is an arc-shaped surface. When the ring plate 201 slides on the wind turbine pile, the arc-shaped surface of the insertion rod 205 contacts the surface of the wind turbine pile. When the insertion rod 205 slides with the ring plate 201, the insertion rod 205 contacts the surface of the pile through the arc-shaped surface, which reduces the wear of the end of the insertion rod 205 on the surface of the pile when the insertion rod 205 moves, thereby increasing the service life of the insertion rod 205.

[0056] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
