Figure 5 As shown, the installation method includes:

[0055] S501 stacks and assembles multiple cylinder segments on the foundation 40 of the wind turbine generator set to form a cylinder section 10 , and the cylinder section 10 includes a first cylinder segment 11 and a second cylinder segment 12 .

[0056] A small crane is used to hoist the pipe segments 13a to assemble into multiple cylinder segments, the bottom end of one of the cylinder segments is fixed to the foundation 40 of the wind turbine generator set, and the other cylinder segments are stacked and assembled in sequence to form a cylinder section 10; wherein, the number of cylinder segments in the cylinder section 10 is greater than or equal to the sum of the positioning structure 200 and the telescopic support structure 300, the cylinder segment corresponding to the positioning structure 200 is used as the first cylinder segment 11, and the cylinder segment corresponding to the telescopic support structure 300 is used as the second cylinder segment 12, and at least one first cylinder segment 11 is located above the second cylinder segment 12, or the first cylinder segment 11 is located below the second cylinder segment 12 and the two are not adjacent.

[0057] S502 connects the positioning structure 200 of the wind turbine installation device to the connecting structure 13b of the first barrel section 11, and the second end of the telescopic support structure 300 is detachably hinged to the connecting structure 13b of the second barrel section 12, so as to fix the mounting frame 100 in the barrel section 10, and the lifting part of the lifting structure 400 is located above the barrel section 10.

[0058] Specifically, the wind turbine installation device can be assembled outside the barrel section 10 and then hoisted into the barrel section 10; or the parts of the wind turbine installation device can be transported into the barrel section 10 for assembly; when the mounting frame 100 is fixed to the barrel section 10 through the positioning structure 200, the upper frame of the mounting frame 100 extends upward from the barrel section 10, and the hoisting part of the hoisting structure 400 is located above the barrel section 10 and the height interval from the top of the barrel section 10 is greater than the height of a pipe segment 13a. Among them, the connection operation of the second end of the telescopic support structure 300 and the connection structure 13b of the second barrel section 12 can also be located in other sequences between step S502 and step S505, and this operation sequence is not limited.

[0059] S503: Load the wind turbine generator set 20 on the top of the mounting frame 100. The wind turbine generator set 20 can be raised and lowered synchronously with the mounting frame 100, so that when the wind power tower is assembled, the wind turbine generator set 20 is synchronously located above the wind power tower, thereby improving the assembly convenience of the wind turbine generator set 20 and eliminating the need for a large crane to hoist the wind turbine generator set 20.

[0060] S504: The pipe segment 13a is hoisted to the top of the cylinder section 10 by the hoisting structure 400 of the wind turbine installation device and assembled to the cylinder section 10 and the adjacent pipe segment 13a until the assembly of a new layer of cylinder sections is completed.

[0061] A plurality of segments 13a are hoisted to the top of the barrel section 10 by using the hoisting structure 400, and the segments 13a and the top of the barrel section 10 and the segments 13a and the adjacent segments 13a are assembled and connected by gluing or the like, so as to assemble a new barrel section at the top of the current barrel section 10, and accordingly form a new barrel section 10. Specifically, the segments 13a and the top of the barrel section 10 and the adjacent segments 13a can be assembled by gluing with epoxy resin structural adhesive.

[0062] S505: Remove the connection between the positioning structure 200 and the first cylinder segment 11, and adjust the support length of the telescopic support structure 300 to drive the mounting frame 100 to rise to the height of the pipe segment 13a. Remove the connection between the positioning structure 200 and the inner connecting structure 13b of the first cylinder segment 11, and the second end of the telescopic support structure 300 is hinged to the inner connecting structure 13b of the second cylinder segment 12, and the height remains unchanged. Adjust the support length of the telescopic support structure 300, and the second end of the telescopic support structure 300 rotates relative to the connecting structure 13b and the first end rotates relative to the mounting frame 100 to drive the mounting frame 100 to rise relative to the cylinder segment 10 by the height distance of one pipe segment 13a. The hoisting structure 400 rises synchronously with the mounting frame 100, thereby ensuring that the hoisting structure 400 is located above the new cylinder segment 10 and the hoisting part hoists the next cylinder segment.

[0063] Specifically, when the second end of the telescopic support structure 300 is lower than the first end, the telescopic support structure 300 is adjusted to extend to increase its support length so as to lift the mounting frame 100 upward by a height distance of a pipe segment 13a; when the second end of the telescopic support structure 300 is higher than the first end, the telescopic support structure 300 is adjusted to retract to reduce its support length so as to pull the mounting frame 100 upward by a height distance of a pipe segment 13a. The height of the pipe segment 13a may be 3m.

[0064] S506: The adjacent cylinder section located above the first cylinder section 11 is used as the new first cylinder section 11, and the adjacent cylinder section located above the second cylinder section 12 is used as the new second cylinder section 12, and this is repeated until all cylinder sections are assembled, and the installation of the wind power hybrid tower is realized. At this time, the height of the cylinder section 10 is increased by one cylinder section, and the relative positions of the wind turbine installation device and the top of the cylinder section 10 are approximately the same as the relative positions of the wind turbine installation device when the wind turbine installation device is initially installed on the cylinder section 10; S502-S506 are repeated until all cylinder sections are assembled, the cylinder section 10 reaches the height requirement, and the assembly of the wind power hybrid tower is completed.

[0065] S507 removes the connection between the positioning structure 200 and the first cylinder section 11, removes the lifting structure 400 and sends it out; adjusts the support length of the telescopic support structure 300 to drive the mounting frame 100 to descend until the wind turbine generator set 20 is overlapped on the top of the wind turbine tower, connects the wind turbine generator set 20 to the top of the wind turbine tower, and removes the connection between the wind turbine generator set 20 and the mounting frame 100. After the wind power hybrid tower is assembled, the partial or entire hoisting structure 400 that radially extends out of the wind power hybrid tower is removed, and sent out through the space between the top of the wind power hybrid tower and the wind turbine generator set 20 or through the inspection port of the wind power hybrid tower, thereby reducing the interference of the hoisting structure 400 on the subsequent descent of the mounting frame 100; the connection between the positioning structure 200 and the connecting structure 13b of the first cylinder section 11 is removed, and the mounting frame 100 is adjusted to descend to a first height through the telescopic support structure 300 to place the wind turbine generator set 20 carried on the top of the mounting frame 100 on the top of the wind power hybrid tower, and then the connection between the wind turbine generator set 20 and the mounting frame 100 is released, and it is fixedly connected to the top of the wind power hybrid tower, so that on the basis 40 of realizing the assembly of the wind power hybrid tower, the assembly of the wind turbine generator set 20 and the wind power hybrid tower can be completed at the same time, thereby improving the assembly convenience of the wind turbine generator set 20 and eliminating the hoisting operation of the wind turbine generator set 20 by a large crane.

[0066] S508: Lower the mounting frame 100 to the top surface of the foundation 40, disassemble the mounting frame 100, the positioning structure 200 and the telescopic support structure 300 and transport them out through the inspection port of the wind power tower. After the wind power tower and the wind turbine generator set 20 are assembled, the mounting frame 100 can be lowered by the reverse operation of the rising of the mounting frame 100 in steps S502 to S506. The specific lowering step may include: adjusting the support length of the telescopic support structure 300 to drive the mounting frame 100 to descend to a second height, the sum of the second height and the first height being the height of one or more pipe segments 13a, so that the positioning structure 200 corresponds to the connecting structure 13b of one of the cylinder segments, and the cylinder segment serves as the first cylinder segment 11; connecting the positioning structure 200 to the connecting structure 13b on the inner side of the first cylinder segment 11, and releasing the connection between the telescopic support structure 300 and the second cylinder segment 12, and then adjusting the telescopic support structure 300 restores the support length so that its second end can be connected to the corresponding connection structure 13b of a cylinder segment below, and this cylinder segment serves as the second cylinder segment 12; then, the second end of the telescopic support structure 300 is connected to the corresponding connection structure 13b of the second cylinder segment 12, and the connection between the positioning structure 200 and the first cylinder segment 11 is released; continuously, the support length of the telescopic support structure 300 is adjusted to drive the mounting frame 100 to descend to a third height, and the third height is an integer multiple of the height of the pipe segment 13a, so that the positioning structure 200 corresponds to the connection structure 13b of one of the cylinder segments below, and this cylinder segment serves as a new first cylinder segment 11, and this is repeated until the mounting frame 100 is lowered to a height close to the foundation 40.

[0067] Subsequently, the positioning structure 200 and the telescopic support structure 300 are removed from the mounting frame 100, and the positioning structure 200, the telescopic support structure 300 and the mounting frame 100 are disassembled into small-volume components according to their volume sizes. The disassembled small-volume components are then transported out through the inspection port at the bottom of the wind power hybrid tower, thereby completing the assembly of the wind power hybrid tower and the wind turbine generator set 20. The wind turbine generator set 20 is assembled on the foundation 40 of the wind power hybrid tower to ensure the transportation of the wind turbine generator set installation device.

[0068] When the wind turbine installation device provided in the present embodiment adopts the wind turbine installation method, the installation frame 100 can be adjusted to rise and fall under the joint action of the positioning structure 200 and the telescopic support structure 300, so that the wind turbine hybrid tower is assembled by hoisting the pipe segment 13a through the hoisting structure 400, and at the same time, the wind turbine generator set 20 can be loaded on the top of the installation frame 100 and rise and fall synchronously with it, and the wind turbine generator set 20 can be assembled with the wind turbine hybrid tower while completing the assembly of the wind turbine hybrid tower, thereby eliminating the need for a large crane to hoist the pipe segment 13a and the wind turbine generator set. The hoisting operation of the unit 20 improves the convenience of installation of the wind power tower, the wind turbine generator set 20 and the wind turbine generator set, and reduces the installation risk; in addition, the wind turbine generator set installation device climbs and descends in the barrel section 10 during use, and is less affected by the external climate, thereby ensuring the operation time and improving the installation efficiency; and the mounting frame 100 of the wind turbine generator set installation device adopts a detachable frame structure, which can be disassembled into small-volume components, and the wind turbine generator set 20 is assembled on the foundation 40 of the wind power tower, ensuring the transportation and reuse of the wind turbine generator set installation device.

[0069] In addition, the positioning structure 200 and the telescopic support structure 300 of the wind turbine installation device are both detachably connected to the same connecting structure 13b of the cylinder segment, thereby reducing the complexity of the connecting structure 13b, reducing the embedded parts set on the inner side of the cylinder segment, and improving the convenience of forming the pipe segment 13a.

[0070] The positioning structure 200 may include a plurality of first connection parts 210 dispersedly arranged along the circumference of the mounting frame 100, the telescopic support structure 300 includes a plurality of telescopic support members dispersedly arranged along the circumference of the mounting frame 100, and the first ends of the plurality of telescopic support members are all hinged to the mounting frame 100; the connection structure 13b of the cylinder segment includes a plurality of second connection parts 13c, and the plurality of second connection parts 13c are dispersedly arranged on the inner side wall of each tube segment 13a, and the second connection part 13c can be specifically arranged at the middle position of each tube segment 13a along the height direction. When in use, the plurality of first connection parts 210 of the positioning structure 200 are detachably connected with the plurality of second connection parts 13c of the corresponding first cylinder segment 11 in a one-to-one correspondence to achieve stable positioning of the mounting frame 100; the second ends of the plurality of telescopic support members of the telescopic support structure 300 are hinged with the plurality of second connection parts 13c of the corresponding second cylinder segment 12 in a one-to-one correspondence to achieve stable support of the mounting frame 100 for lifting and lowering drive. Specifically, the first connecting part 210 and the second connecting part 13c can both be connecting ears with connecting holes, and the two can be detachably connected by bolts and nuts; the second end of the telescopic support structure 300 can also be set as a connecting ear with a connecting hole, similar to being hinged with the second connecting part 13c by a pin.

[0071] In this embodiment, when the mounting frame 100 carries the wind turbine generator set 20 and rises to a preset height, the wind turbine blades 30 of the wind turbine generator set are hoisted to the wind turbine generator set 20; wherein the preset height is greater than the length of the wind turbine blades 30 in the wind turbine generator set.

The first ends of the plurality of interlayer beams 151 of the interlayer frame are connected to each other, and the second ends extend radially outward as the radial ends; in this embodiment, the interlayer frame of the mounting frame 100 is utilized, and the first connecting parts 210 are arranged at the radial ends of the plurality of interlayer beams 151 thereof, so as to complete the arrangement of the positioning structure 200 and ensure the dispersed arrangement of the plurality of first connecting parts 210 along the circumference, and the assembly of the positioning structure 200 can be completed when the interlayer frame is assembled to the side frame 110, thereby improving the structural simplicity of the mounting device and the convenience of assembly and disassembly of the mounting device.

[0078] Specifically, a first connecting portion 210 can be provided at the second end of the partition beam 151 in each partition frame. During installation, one or more of them can be selected as the positioning frame 16A as needed, and the corresponding first connecting portion 210 is used as the positioning structure 200 for connection with the first cylinder section 11, thereby improving the flexibility of use of the positioning structure 200 and the installation device.

[0079] In this embodiment, Figure 1 and Figure 3 As shown, the spacing height between the bottom partition frame 140 and the adjacent middle partition frame 130 is consistent with the height of the tube segment 13a, the spacing height between the adjacent middle partition frames 130 is consistent with the height of the tube segment 13a, and the spacing height between the top partition frame 120 and the adjacent middle partition frame 130 is less than the height of the tube segment 13a. When in use, one or more of the bottom partition frame 140 and the middle partition frame 130 can be used as the positioning frame 16A as needed, and it can ensure that multiple positioning frames 16A are connected to the connection structure 13b of the multi-layer cylinder section in the cylinder section 10 in a one-to-one correspondence; in addition, the top partition frame 120 is higher than the middle partition frame 130, and on the basis of ensuring non-interference and stable bearing of the wind turbine generator set 20, the overall height and space occupation of the mounting frame 100 are effectively reduced, and the overall stability of the mounting frame 100 and its smooth lifting and lowering in the cylinder section 10 are correspondingly improved.

When the cylinder segments are stacked, the multiple second connecting parts 13c on the inner side of the same cylinder segment are dispersedly arranged along its circumference to form a connecting structure 13b, and the height interval of the connecting structures 13b of adjacent cylinder segments is approximately the height of one tube segment 13a; the positioning structures 200 of this embodiment are set as two groups and the interval height is twice the height of the tube segment 13a.
