[0044] S501: A plurality of cylinder sections are stacked and assembled on the foundation 40 of the wind turbine to form a cylinder section 10, and the cylinder section 10 includes a first cylinder section 11 and a second cylinder section 12.

[0045] A small crane is used to hoist the pipe pieces 13a to assemble a plurality of cylinder sections, the bottom end of one of the cylinder sections is fixed to the foundation 40 of the wind turbine, and the other cylinder sections are sequentially stacked and assembled to form a cylinder section 10; wherein the number of cylinder sections in the cylinder section 10 is greater than or equal to the sum of the positioning structure 200 and the extendable support structure 300, the cylinder section corresponding to the positioning structure 200 is used as the first cylinder section 11, and the cylinder section corresponding to the extendable support structure 300 is used as the second cylinder section 12, and at least one first cylinder section 11 is located above the second cylinder section 12, or the first cylinder section 11 is located below the second cylinder section 12 and the two are not adjacent.

[0047] Specifically, the assembly of the wind turbine installation device can be completed outside the cylinder section 10, and then hoisted into the cylinder section 10; or the parts of the wind turbine installation device are transported into the cylinder section 10 for assembly; when the mounting frame 100 is fixed to the cylinder section 10 by the positioning structure 200, the upper frame body of the mounting frame 100 extends upward out of the cylinder section 10, and the hoisting part of the hoisting structure 400 is located above the cylinder section 10 and spaced apart from the top end of the cylinder section 10 by a height greater than that of one pipe piece 13a. The connection operation of the second end of the telescopic support structure 300 to the connecting structure 13b of the second cylinder section 12 can also be in other orders between steps S502 and S505, and the operation order is not limited.

[0048] S503 loads the wind turbine generator 20 on the top of the mounting frame 100. The wind turbine generator 20 can be lifted synchronously with the mounting frame 100, so that when the wind turbine hybrid tower is assembled, the wind turbine generator 20 is located above the wind turbine hybrid tower, thereby improving the convenience of assembling the wind turbine generator 20 and saving the lifting operation of the large crane on the wind turbine generator 20.

[0049] S504 hoists the pipe piece 13a to the top of the cylinder section 10 by the hoisting structure 400 of the wind turbine installation device and assembles it to the cylinder section 10 and the adjacent pipe piece 13a, until the assembly of a new layer of cylinder section is completed.

[0050] The hoisting structure 400 is used to hoist a plurality of pipe pieces 13a to the top end of the cylinder section 10, and the pipe pieces 13a are assembled and connected with the top end of the cylinder section 10 and the adjacent pipe pieces 13a by gluing, so as to assemble a new cylinder section at the top end of the current cylinder section 10, and a new cylinder section 10 is formed. Specifically, the pipe pieces 13a and the top end of the cylinder section 10 and the adjacent pipe pieces 13a can be assembled by epoxy resin structure glue.

[0051] S505 disconnect the positioning structure 200 from the first cylinder segment 11, adjust the support length of the telescopic support structure 300 to drive the mounting frame 100 to ascend the height of one pipe piece 13a. Disconnect the positioning structure 200 from the connecting structure 13b inside the first cylinder segment 11, the second end of the telescopic support structure 300 is hinged to the connecting structure 13b inside the second cylinder segment 12 and the height is fixed, adjust the support length of the telescopic support structure 300, 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 ascend the height of one pipe piece 13a, the lifting structure 400 synchronously ascends with the mounting frame 100, thereby ensuring that the lifting structure 400 is above the new cylinder segment 10 and the lifting part lifts the next cylinder segment.

[0052] Specifically, when the second end of the telescopic support structure 300 is lower than the first end, adjust the telescopic support structure 300 to expand to increase the support length to upwardly lift the mounting frame 100 to ascend the height of one pipe piece 13a; when the second end of the telescopic support structure 300 is higher than the first end, adjust the telescopic support structure 300 to retract to decrease the support length to upwardly pull the mounting frame 100 to ascend the height of one pipe piece 13a. Wherein, the height of the pipe piece 13a can be 3m.

[0053] S506 take the adjacent cylinder segment above the first cylinder segment 11 as the new first cylinder segment 11, take the adjacent cylinder segment above the second cylinder segment 12 as the new second cylinder segment 12, repeat the above process until the assembly of all cylinder segments is completed, and the installation of the wind power hybrid tower is realized. At this time, the height of the cylinder segment 10 increases by one cylinder segment, and the relative position of the wind power unit installation device and the top end of the cylinder segment 10 is approximately the same as that when the wind power unit installation device is initially installed on the cylinder segment 10; repeat S502-S506 until the assembly of all cylinder segments is completed, the cylinder segment 10 reaches the height requirement, and the assembly of the wind power hybrid tower is completed.

[0054] S507, disconnecting the positioning structure 200 from the first cylinder section 11, removing the hoisting structure 400 and sending it out; adjusting 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 power hybrid tower, connecting the wind turbine generator set 20 to the top of the wind power hybrid tower, and disconnecting the wind turbine generator set 20 from the mounting frame 100. The wind power hybrid tower is assembled, the part of the hoisting structure 400 extending radially out of the wind power hybrid tower or the whole hoisting structure 400 is removed, and is sent out through the space between the top of the wind power hybrid tower and the wind turbine generator set 20 or through the access hole of the wind power hybrid tower, thereby reducing the interference of the hoisting structure 400 on the subsequent descent of the mounting frame 100; disconnecting the connection structure 13b between the positioning structure 200 and the first cylinder section 11, adjusting the mounting frame 100 to descend by a first height through the telescopic support structure 300, so as 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, then disconnecting the wind turbine generator set 20 from the mounting frame 100 and fixedly connecting it to the top of the wind power hybrid tower, so that the wind turbine generator set 20 and the wind power hybrid tower can be assembled simultaneously on the basis 40 of the wind power hybrid tower, thereby improving the assembly convenience of the wind turbine generator set 20 and saving the hoisting operation of the large crane on the wind turbine generator set 20.

[0055] S508, lowering the mounting frame 100 to the top surface of the foundation 40, disassembling the mounting frame 100, the positioning structure 200 and the telescopic support structure 300 and transporting them out through the access hole of the wind power hybrid tower. After the wind power hybrid tower and the wind turbine generator set 20 are assembled, the mounting frame 100 can be lowered by using the reverse operation of the mounting frame 100 ascending in steps S502-S506, and the specific descending steps can include: adjusting the support length of the telescopic support structure 300 to drive the mounting frame 100 to descend by a second height, the sum of the first height and the second height being the height of one or more pipe sections 13a, so that the positioning structure 200 corresponds to the connection structure 13b of one of the cylinder sections as the first cylinder section 11; connecting the positioning structure 200 to the connection structure 13b on the inner side of the first cylinder section 11, and disconnecting the telescopic support structure 300 from the second cylinder section 12, then adjusting the telescopic support structure 300 to restore the support length so that the second end thereof can be connected to the connection structure 13b of one of the cylinder sections below as the second cylinder section 12; then connecting the second end of the telescopic support structure 300 to the connection structure 13b of the corresponding second cylinder section 12, and disconnecting the positioning structure 200 from the first cylinder section 11; continuing to adjust the support length of the telescopic support structure 300 to drive the mounting frame 100 to descend by a third height, the third height being an integer multiple of the height of the pipe section 13a, so that the positioning structure 200 corresponds to the connection structure 13b of one of the cylinder sections below as the new first cylinder section 11, and the process is repeated until the mounting frame 100 is lowered to a height close to the foundation 40.

[0056] Subsequently, the positioning structure 200 and the telescopic support structure 300 are detached from the mounting rack 100, and the positioning structure 200, the telescopic support structure 300 and the mounting rack 100 are disassembled into small-volume components according to the size, and then the disassembled small-volume components are transported out through the maintenance opening at the bottom end of the wind power hybrid tower, thereby completing the assembly of the wind power hybrid tower and the wind turbine generator set 20, and ensuring the transportation of the wind turbine generator set installation device when the wind turbine generator set 20 is assembled on the foundation 40 of the wind power hybrid tower.

[0057] Therefore, when the wind turbine generator set installation device is used, the mounting rack 100 can be adjusted in height by the combined action of the positioning structure 200 and the telescopic support structure 300, so that the assembly of the wind power hybrid tower is completed by the hoisting of the pipe piece 13a by the hoisting structure 400, and the top of the mounting rack 100 can load the wind turbine generator set 20 to be lifted synchronously, so that the assembly of the wind turbine generator set 20 and the wind power hybrid tower is completed at the same time as the assembly of the wind power hybrid tower, thereby eliminating the hoisting operation of the pipe piece 13a and the wind turbine generator set 20 by a large crane, improving the installation convenience of the wind power hybrid tower, the wind turbine generator set 20 and the wind turbine generator set, and reducing the installation risk; in addition, the wind turbine generator set installation device is used to climb and descend in the barrel segment 10, which is less affected by external climate, thereby ensuring the operation time and improving the installation efficiency; and the mounting rack 100 of the wind turbine generator set installation device adopts a detachable rack structure, which can be disassembled into small-volume components, thereby ensuring the transportation and reuse of the wind turbine generator set installation device when the wind turbine generator set 20 is assembled on the foundation 40 of the wind power hybrid tower.

[0058] In addition, the positioning structure 200 and the telescopic support structure 300 of the wind turbine generator set installation device are detachably connected with the same connecting structure 13b of the barrel segment, thereby reducing the complexity of the connecting structure 13b, reducing the embedded parts provided inside the barrel segment, and improving the forming convenience of the pipe piece 13a.

[0059] The positioning structure 200 can include a plurality of first connecting portions 210 arranged along the circumference of the mounting frame 100, the telescopic support structure 300 includes a plurality of telescopic supports arranged along the circumference of the mounting frame 100, and the first ends of the plurality of telescopic supports are hinged to the mounting frame 100. The connecting structure 13b of the cylinder segment includes a plurality of second connecting portions 13c, and the plurality of second connecting portions 13c are arranged on the inner side wall of each pipe piece 13a. The second connecting portion 13c can be arranged at the middle position of each pipe piece 13a in the height direction. In use, the plurality of first connecting portions 210 of the positioning structure 200 are detachably connected with the plurality of second connecting portions 13c of the corresponding first cylinder segment 11 one by one to achieve stable positioning of the mounting frame 100; the second ends of the plurality of telescopic supports of the telescopic support structure 300 are hinged with the plurality of second connecting portions 13c of the corresponding second cylinder segment 12 one by one to achieve stable support of the mounting frame 100 for lifting drive. Specifically, the first connecting portion 210 and the second connecting portion 13c can be connecting ears with connecting holes, and detachable connection can be achieved between the two through bolts and nuts; the second end of the telescopic support structure 300 can also be provided as a connecting ear with a connecting hole, and the hinge connection with the second connecting portion 13c can be achieved through a pin.

[0060] In the embodiment, when the mounting frame 100 carrying the wind turbine generator set 20 rises to a preset height, the wind turbine blades 30 of the wind turbine generator set are hoisted on 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. During the process of continuously rising of the mounting frame 100 carrying the wind turbine generator assembly, the distance between the wind turbine generator assembly and the ground 50 also continuously increases. When the distance between the axis of the wind turbine generator set 20 and the ground 50, i.e. the preset height, is greater than the length of the wind turbine blades 30 in the wind turbine generator set, the wind turbine blades 30 can be hoisted and assembled on the wind turbine generator set 20 through a small crane, so as to ensure that the wind turbine blades 30 assembled on the wind turbine generator set 20 have a height from the ground 50 without interference with the ground 50. Subsequently, the mounting frame 100 simultaneously carries the wind turbine generator set 20 and the wind turbine blades 30 to rise synchronously, and the assembly of the wind turbine blades 30 is realized at the same time when the assembly of the wind turbine generator set 20 on the wind power hybrid tower is completed. The mounting device of the embodiment can simultaneously complete the assembly of the wind power hybrid tower, the wind turbine generator set 20 and the wind turbine blades 30 in the wind turbine generator set, and the entire process does not need hoisting by a large crane, thereby further improving the installation convenience and installation efficiency of the wind turbine generator set, and further reducing the installation risk.

[0061] In this embodiment, the step S507 removes the hoisting structure 400 and sends it out, including: disassembling the hoisting structure 400 and its connection with the mounting frame 100, using the maintenance winch in the wind turbine generator set 20 to hoist the disassembled parts of the hoisting structure 400 to the top surface of the foundation 40, and then transported out through the maintenance opening of the wind power hybrid tower. After the wind power hybrid tower is assembled, the connection between the hoisting structure 400 and the mounting frame 100 can be released, and the hoisting structure 400 can be disassembled into small volume parts. Then, the maintenance winch in the wind turbine generator set 20 can be used to hoist the small volume parts of the hoisting structure 400 downward to the top surface of the foundation 40, and then the small volume parts are transported out through the maintenance opening of the wind power hybrid tower, completing the disassembly and transportation of the hoisting structure 400. This process does not require the use of a large crane, further improving the installation convenience and efficiency of the wind turbine generator set, and further reducing the installation risk.

[0062] In this embodiment, as shown in Figures 1-4 The mounting frame 100 can have the following structure: the mounting frame 100 includes a cylindrical side wall frame body 110 and a plurality of layer partition frame bodies arranged in the interior of the side wall frame body 110 and spaced apart in the height direction.

In addition, the layer frame body can also serve as an operation platform, and the operator can climb the ladder 13d inside the cylinder segment 10 to the layer frame body at the desired height to perform disassembly and assembly operations of the positioning structure 200 and the telescopic support structure 300 and hoisting control operations of the hoisting structure 400. The top layer frame body 120 is used to bear the wind turbine generator set 20 to improve the bearing stability and firmness of the mounting frame 100 to the wind turbine generator set 20.
