[0013] Step 1: Install the installation device on the installation platform, and adjust the support rod to the state of extending the support rod;

[0014] Step 2: Use a lifting device to hoist the tilting buoy, and adjust the tilting buoy until the cantilever pin of the tilting buoy is directly opposite to the connecting groove on the hinge seat, and then gradually lower the tilting buoy so that the cantilever pin is stuck in the connecting groove of the hinge seat;

[0015] Step 3: The hook of the lifting equipment is lowered, and the cantilever pin of the tilting buoy rotates in the connecting groove under the action of its own weight until the bottom of the tilting buoy is flush with the upper surface of the installation platform, and the hook of the lifting equipment stops descending;

The present invention can improve the installation efficiency of the inclined pontoon, which is beneficial to shortening the construction period and avoiding damage to the structure of the installation platform.

[0037] like Figures 1 to 13 As shown, a preferred embodiment of an embodiment of the present invention is an installation device for an inclined pontoon of a floating wind turbine foundation, wherein an installation platform 1 is provided at the end of a concrete precast arm in the floating wind turbine foundation, an inclined pontoon 2 is installed on the installation platform 1, and at least two groups of the installation devices 3 are provided on the installation platform 1, wherein the installation device 3 comprises a mounting seat 31, a hinge seat 32, a first cushion block group 33, a second cushion block group 34 and a retractable adjustment support rod 35, wherein the adjustment support rod 35 is preferably an adjustment cylinder, the hinge seat 32 is arranged on the top surface of the mounting seat 31, a connecting groove 321 is provided on the hinge seat 32, and the connecting groove 321 is preferably a U-shaped groove, a cantilever pin 21 rotatably matched with the connecting groove 321 is provided at the bottom of the inclined pontoon 2, a downwardly protruding convex seat 311 is provided at the bottom of the mounting seat 31, and the first cushion block group 33 is arranged on the mounting platform 1 Between 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 first pad located at the top is connected to the boss 311 by bolts, and the outer edge of the first pad located at the bottom is connected to the mounting platform 1 by bolts; the second pad group 34 is arranged between the adjustment 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 adjustment support rod 35 is connected to the mounting seat 31, the bottom of the adjustment support rod 35 is connected to the outer edge of the second pad located at the top by bolts, and the outer edge of the second pad located at the bottom is connected to the mounting platform 1 by bolts, that is, the overall mounting device 3 is bolted to the mounting platform 1.

[0038] Exemplarily, an inverted "J" shape is formed between the mounting seat 31 and the boss 311, and two adjustment support rods 35 are provided on the mounting seat 31, and the two adjustment support rods 35 are respectively located on both sides of the boss 311, thereby improving the support stability of the inclined buoy 2.

[0039] Exemplarily, the thickness of the first pad block is smaller than the maximum stroke of the adjusting cylinder, so that when the adjusting cylinder is extended or retracted, the first pad block can be conveniently taken out, and after the support rod of the adjusting cylinder is retracted, the protrusion 311 can be pressed against the top surface of the first pad block group 33, so as to ensure that the mounting seat 31 and the protrusion 311 can always be effectively supported; specifically, the height of the first pad block group 33 is higher than the height of the second pad block group 34, so that it is convenient to adjust the distance between the mounting seat 31 and the mounting platform 1 step by step.

[0040] Exemplarily, the thickness of the first pad is different from the thickness of the second pad, so that after the first pad is removed from the first pad group 33 and the second pad is removed from the second pad group 34, 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 cylinder telescopic adjustment mounting seat 31.

[0041] Exemplarily, the mounting devices 3 are provided in two groups and are respectively located on both sides of the inclined buoy 2 , so as to effectively and stably support the inclined buoy 2 .

[0042] The present invention also provides a method for installing the inclined buoy 2 of the floating wind turbine foundation, using the installation device 3 of the inclined buoy 2 of the floating wind turbine foundation to install the inclined buoy 2 on the installation platform 1, comprising 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 a state of extending the support rod;

[0044] Step 2: The lifting equipment 4 hoists the tilting buoy 2, and adjusts the tilting buoy 2 until the cantilever pin 21 of the tilting buoy 2 is directly opposite to the connecting groove 321 on the hinge seat 32, and then gradually lowers the tilting buoy 2 so that the cantilever pin 21 is inserted into the connecting groove 321 of the hinge seat 32;

[0045] Step 3: The hook of the lifting device 4 is lowered, and the cantilever pin 21 of the tilting buoy 2 rotates in the connecting groove 321 under the action of its own weight until the bottom of the tilting buoy 2 is flush with the upper surface of the installation platform 1, and the hook of the lifting device 4 stops descending;

[0046] Step 4: Tilt buoy 2 downward adjustment operation as follows Figure 6 to Figure 13As shown, the first cushion block on the top of the first cushion block group 33 is removed, and then the adjustment support rod 35 is retracted and the hook of the lifting device 4 is synchronously lowered, so that the protrusion 311 is pressed against the top surface of the first cushion block group 33, and then the second cushion block on the top of the second cushion block group 34 is removed, and then the adjustment support rod 35 is extended to make the top of the adjustment support rod 35 press against the mounting seat 31, and the bottom of the adjustment support rod 35 presses against the second cushion block group 34;

[0047] Step 5: Repeat step 4 until the first and second gaskets are completely removed, and at the same time, the bottom flange surface of the tilted buoy 2 is fitted with the flange surface of the mounting platform 1, and the bottom flange surface of the tilted buoy 2 is connected with the flange surface of the mounting platform 1 by bolts.

[0048] In summary, the present invention can quickly adjust the installation angle of the tilted pontoon 2 by rotating the connecting groove 321 of the hinge seat 32 with the cantilever pin shaft 21, and cooperate with the lifting equipment 4. Since the installation spacing between the lower end of the tilted pontoon 2 and the installation platform 1 is small, there is a limitation on the installation height, and it is difficult to use a large-stroke adjustment support rod 35 to complete the height adjustment at one time. The height of the tilted pontoon 2 is lowered by gradually removing the first pad and the second pad so that the bottom flange surface of the tilted pontoon 2 fits the flange surface of the installation platform 1, and the lower groove of the tilted pontoon 2 is not damaged. The present invention can improve the installation efficiency of the tilted pontoon 2, which is beneficial to shortening the construction period, and there is no need to weld a limit plate on the installation platform 1 to avoid damaging the structure of the installation platform 1.
