Description

Technical Field

[0001] This invention relates to the field of floating wind turbine foundation technology, and in particular to an installation device and method for an inclined pontoon of a floating wind turbine foundation. Background Technology

[0002] The Y-type floating wind turbine foundation consists of two angled precast concrete arm sections and one vertical precast concrete arm section. An installation platform is located at the end of each precast concrete arm section, and an angled pontoon is installed above the platform. The pontoon is externally clad in fiberglass and is fixedly connected to the inner flange of the installation platform. The outer flange is welded. A lifting lug is located at the top of the pontoon, and a cantilever pin is located on the outer side of the bottom of the pontoon. The conventional installation method for the pontoon is to first install a limiting plate on the upper surface of the installation platform, then use a crane to lift the top lifting lug of the pontoon, hoist the pontoon above the installation platform, and slowly lower it until the bottom of the pontoon abuts the limiting plate. Then, the pontoon is slowly depressurized, and the approximate installation angle is adjusted. Once the pontoon is almost in place, a jack is used to precisely adjust the installation angle until the pontoon flange fits snugly with the installation platform flange. Installation bolts are then used to secure the pontoon flange and the installation platform flange. However, this installation operation can damage the bevel of the bottom of the pontoon. Summary of the Invention

[0003] The problem to be solved by the present invention is to provide an installation device and method for the inclined pontoon of a floating wind turbine foundation, which can effectively improve the installation efficiency of the inclined pontoon, shorten the construction cycle, and avoid damage to the structure of the installation platform.

[0004] To address the aforementioned technical problems, this invention provides an installation device for an inclined pontoon of a floating wind turbine foundation. The end of the precast concrete arm in the floating wind turbine foundation is provided with an installation platform. The inclined pontoon is installed on the installation platform, which is equipped with at least two sets of the installation device. Each installation device includes a mounting base, a hinge base, a first set of pads, a second set of pads, and a telescopic adjusting support rod. The hinge base is located on the top surface of the mounting base and has a connecting groove. The bottom of the inclined pontoon is provided with a cantilever pin that rotatably engages with the connecting groove. The bottom of the mounting base has a downwardly protruding boss. The first set of pads is located on the mounting platform and... Between the protrusions, the first pad group includes at least two stacked first pads, adjacent first pads are detachably connected, the top first pad is detachably connected to the protrusion, and the bottom first pad is detachably connected to the mounting platform; the second pad group is disposed between the adjusting support rod and the mounting platform, the second pad group includes at least two stacked second pads, adjacent second pads are detachably connected, the top of the adjusting support rod is connected to the mounting base, the bottom of the adjusting support rod is detachably connected to the top second pad, and the bottom second pad is detachably connected to the mounting platform.

[0005] As a preferred embodiment of the invention, the mounting base and the protrusion form an inverted "V" shape, and the mounting base is provided with two adjustment support rods, which are respectively located on both sides of the protrusion.

[0006] As a preferred embodiment of the invention, the adjusting support rod is an adjusting hydraulic cylinder.

[0007] As a preferred embodiment of the invention, the thickness of the first pad is less than the maximum stroke of the adjusting cylinder.

[0008] As a preferred embodiment of the invention, the height of the first pad group is higher than the height of the second pad group.

[0009] As a preferred embodiment of the invention, the thickness of the first pad is different from the thickness of the second pad.

[0010] As a preferred embodiment of the invention, the connecting groove is a U-shaped groove.

[0011] As a preferred embodiment of the invention, the mounting device is provided in two sets and is located on both sides of the inclined pontoon.

[0012] The present invention also provides a method for installing an inclined pontoon of a floating wind turbine foundation, wherein the inclined pontoon is installed on an installation platform using the aforementioned installation device for the inclined pontoon of the floating wind turbine foundation, comprising the following steps:

[0013] Step 1: Install the installation device on the installation platform and adjust the support rod to be in the extended support rod position;

[0014] Step 2: The lifting equipment hoists the tilting pontoon and adjusts it so that the cantilever pin of the tilting pontoon is aligned with the connecting groove on the hinge seat. Then, the tilting pontoon is gradually lowered so that the cantilever pin is engaged in the connecting groove of the hinge seat.

[0015] Step 3: As the lifting equipment hook descends, the cantilever pin of the inclined pontoon rotates within the connecting groove under its own weight until the bottom of the inclined pontoon is flush with the upper surface of the installation platform, at which point the lifting equipment hook stops descending.

[0016] Step 4: Remove the first pad block from the top of the first pad block group, then retract the adjusting support rod and lower the lifting hook of the lifting equipment simultaneously, so that the convex seat is pressed against the top surface of the first pad block group. Then remove the second pad block from the top of the second pad block group. After that, extend the adjusting support rod so that the top of the adjusting support rod is pressed against the mounting seat and the bottom of the adjusting support rod is pressed against the second pad block group.

[0017] Step 5: Repeat Step 4 until the first and second pads are completely removed. At the same time, the bottom flange of the inclined pontoon is aligned with the flange of the mounting platform. The bottom flange of the inclined pontoon and the flange of the mounting platform are then connected by bolts.

[0018] The present invention provides an installation device and method for inclined pontoons of a floating wind turbine foundation. Compared with the prior art, its advantages are as follows:

[0019] This invention utilizes the connecting groove of the hinge seat and the rotatable pin shaft to quickly adjust the installation angle of the inclined pontoon in conjunction with lifting equipment. Due to the small installation distance between the lower opening of the inclined pontoon and the installation platform, there is a limitation on the installation height, making it difficult to complete the height adjustment in one go using a large-stroke adjustment support rod. By gradually removing the first and second pads, the height of the inclined pontoon is reduced, allowing the bottom flange surface of the inclined pontoon to fit against the flange surface of the installation platform without damaging the bevel of the lower opening of the inclined pontoon. This invention can improve the installation efficiency of the inclined pontoon, shorten the construction cycle, and avoid damaging the structure of the installation platform.

Detailed Implementation

[0035] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0036] In the description of this invention, it should be understood that the terms "upper," "lower," "left," "right," "top," "bottom," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be understood that the terms "first," "second," etc., are used in this invention to describe various information, but this information should not be limited to these terms; these terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this invention, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.

[0037] like Figures 1 to 13 As shown in the preferred embodiment of the present invention, an installation device for an inclined pontoon of a floating wind turbine foundation is provided. The end of the precast concrete arm in the floating wind turbine foundation is provided with an installation platform 1. The inclined pontoon 2 is installed on the installation platform 1. At least two sets of installation devices 3 are provided on the installation platform 1. Each installation device 3 includes a mounting base 31, a hinge base 32, a first pad group 33, a second pad group 34, and a telescopic adjusting support rod 35. The adjusting support rod 35 is preferably an adjusting cylinder. The hinge base 32 is located on the top surface of the mounting base 31 and has a connecting groove 321, preferably a U-shaped groove. The bottom of the inclined pontoon 2 is provided with a cantilever pin 21 that rotatably engages with the connecting groove 321. The bottom of the mounting base 31 is provided with a downwardly protruding boss 311. The first pad group 33 is located on the installation platform 1. Between the first pad group 33 and the boss 311, the first pad group 33 includes at least two stacked first pads. The outer edges of adjacent first pads are connected by bolts. The outer edge of the top first pad is connected to the boss 311 by bolts, and the outer edge of the bottom first pad is connected to the mounting platform 1 by bolts. The second pad group 34 is disposed between the adjusting support rod 35 and the mounting platform 1. The second pad group 34 includes at least two stacked second pads. The outer edges of adjacent second pads are connected by bolts. The top of the adjusting support rod 35 is connected to the mounting base 31. The bottom of the adjusting support rod 35 is connected to the outer edge of the top second pad by bolts, and the outer edge of the bottom second pad is connected to the mounting platform 1 by bolts. That is, the overall mounting device 3 is bolted to the mounting platform 1.

[0038] For example, the mounting base 31 and the protrusion 311 form an inverted "V" shape. The mounting base 31 is provided with two adjustment support rods 35, and the two adjustment support rods 35 are respectively located on both sides of the protrusion 311, thereby improving the support stability of the inclined pontoon 2.

[0039] For example, the thickness of the first pad is less than the maximum stroke of the adjusting cylinder. This ensures that when the adjusting cylinder extends or retracts, the first pad can be easily removed, and after the support rod of the adjusting cylinder retracts, the protrusion 311 can press against the top surface of the first pad group 33, ensuring that the mounting base 31 and the protrusion 311 can always be effectively supported. Specifically, the height of the first pad group 33 is higher than the height of the second pad group 34, which facilitates the step-by-step adjustment of the distance between the mounting base 31 and the mounting platform 1.

[0040] For example, the thickness of the first pad is different from the thickness of the second pad. This way, after the first pad group 33 removes the first pad and the second pad group 34 removes the second pad, a height difference is formed between the first pad group 33 and the second pad group 34, which facilitates the adjustment of the position of the hydraulic cylinder extension and retraction adjustment mounting seat 31.

[0041] For example, the installation device 3 is provided in two sets and is located on both sides of the inclined pontoon 2 respectively, which effectively and stably supports the inclined pontoon 2.

[0042] The present invention also provides a method for installing the inclined pontoon 2 of a floating wind turbine foundation, wherein the inclined pontoon 2 is installed on the installation platform 1 using the installation device 3 for the inclined pontoon 2 of the floating wind turbine foundation, and includes the following steps:

[0043] Step 1: Install the mounting device 3 on the mounting platform 1, and adjust the support rod 35 to be in the extended support rod state;

[0044] Step 2: The lifting equipment 4 hoists the inclined pontoon 2 and adjusts the inclined pontoon 2 so that the cantilever pin 21 of the inclined pontoon 2 is directly aligned with the connecting groove 321 on the hinge seat 32. Then, the inclined pontoon 2 is gradually lowered so that the cantilever pin 21 is engaged in the connecting groove 321 of the hinge seat 32.

[0045] Step 3: The hook of the lifting equipment 4 descends, and under its own weight, the cantilever pin 21 of the inclined float 2 rotates in the connecting groove 321 until the bottom of the inclined float 2 is flush with the upper surface of the installation platform 1, and the hook of the lifting equipment 4 stops descending.

[0046] Step 4: Adjust the descent of the tilting buoy 2 as follows Figures 6 to 13As shown, the first pad block at the top of the first pad block group 33 is removed, and then the adjusting support rod 35 is retracted and the hook of the lifting equipment 4 is lowered synchronously, so that the boss 311 abuts against the top surface of the first pad block group 33. Then the second pad block at the top of the second pad block group 34 is removed, and then the adjusting support rod 35 is extended out of the support rod, so that the top of the adjusting support rod 35 abuts against the mounting seat 31 and the bottom of the adjusting support rod 35 abuts against the second pad block group 34.

[0047] Step 5: Repeat step 4 until the first and second pads are completely removed. At the same time, the bottom flange of the inclined pontoon 2 is aligned with the flange of the mounting platform 1. The bottom flange of the inclined pontoon 2 and the flange of the mounting platform 1 are connected by bolts.

[0048] In summary, this invention utilizes the rotatable engagement between the connecting groove 321 of the hinge seat 32 and the cantilever pin 21, along with the lifting equipment 4, to quickly adjust the installation angle of the inclined pontoon 2. Since the installation distance between the lower opening of the inclined pontoon 2 and the installation platform 1 is small, there is a limitation on the installation height, making it difficult to complete the height adjustment in one go using a large-stroke adjustment support rod 35. By gradually removing the first and second pads, the height of the inclined pontoon 2 is reduced, allowing the bottom flange surface of the inclined pontoon 2 to fit against the flange surface of the installation platform 1 without damaging the lower opening bevel of the inclined pontoon 2. This invention improves the installation efficiency of the inclined pontoon 2, shortens the construction cycle, and eliminates the need to weld a limiting plate onto the installation platform 1, thus avoiding damage to the structure of the installation platform 1.
