Description

Technical Field

[0001] This invention belongs to the field of offshore wind power generation technology, and particularly relates to an assembly device for offshore wind turbine rotors. Background Technology

[0002] Wind power is the world's fastest-growing green energy technology. While onshore wind farms are rapidly developing, limitations have become apparent, such as large land area requirements and noise pollution. Due to abundant offshore wind resources and the feasibility of current technologies, the ocean is poised to become a rapidly developing wind power market. Offshore wind farms in Europe and America are on the verge of large-scale development. my country's eastern coastal areas have vast waters within 50 meters of depth, and are close to power load centers (economically developed coastal areas with power shortages). With the maturation of offshore wind farm technology, wind power will undoubtedly become a crucial energy source for the sustainable development of my country's eastern coastal regions. In offshore wind power generation, the rotor is a critical component. Its large size and weight necessitate precise installation and alignment. Once misalignment occurs, readjustment can easily lead to over-adjustment, resulting in prolonged time consumption and low efficiency.

[0003] To address the above issues, it is necessary to design an assembly device for offshore wind turbine rotors that can be precisely positioned. Summary of the Invention

The setting of the ball bearings and the outer wall of the ball bearings being in close contact with the bottom of the limiting ring plate can change the sliding friction between the upper movable base mechanism and the lower fixed base mechanism into rolling friction, thereby greatly reducing frictional resistance.

[0023] The lower frame has a fixing groove on its bottom outer side and a positioning hole on its inner wall. The fixing groove and positioning hole in the lower frame facilitate the fixed installation of the component on a base such as a ship.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0044] This invention provides an assembly device for an offshore wind turbine rotor, including a bottom mounting base assembly 1, a calibration assembly 2, a leveling assembly 3, an auxiliary bracket assembly 4, and an adjustment bracket assembly 5. The calibration assembly 2 includes a mounting shell 201, and a central calibration infrared probe 205 is fixedly connected to the inner wall of the mounting shell 201.

[0045] Several external support rods 204 are fixedly connected to the outer wall of the mounting shell 201. One end of the external support rod 204 is fixedly connected to the front frame 203. The several external support rods 204 are arranged in a ring between the mounting shell 201 and the front frame 203. Several monitoring probes 202 are arranged in a ring on the outer wall of the front frame 203.

[0046] The top of the bottom mounting base assembly 1 is fixedly connected to the cylinder bottom groove 11, the inner wall of the cylinder bottom groove 11 is fixedly connected to the second large hydraulic cylinder 10, the outer wall of the cylinder bottom groove 11 is slidably connected to the upper slide 12, and the top of the second large hydraulic cylinder 10 is fixedly connected to the bottom of the upper slide 12.

[0047] The outer wall of the upper slide 12 is provided with a main limiting groove. The inner wall of the main limiting groove is slidably connected to the outer wall of the main slide rod 5011. The outer wall of the upper slide 12 is provided with two auxiliary rod limiting grooves. The inner walls of the two auxiliary rod limiting grooves are slidably connected to the outer wall of the auxiliary slide rod 5013.

[0048] The top of the bottom mounting base assembly 1 is fixedly connected to the upper support 9, and the outer wall of the upper support 9 is fitted and connected to the inner wall of the auxiliary lifting platform 4011.

[0049] It should be noted that, as the rotor is a crucial component in offshore wind power generation, its structure and weight are both substantial. Precise installation and alignment are required. Once a misalignment occurs, readjustment can easily lead to over-adjustment, resulting in prolonged time consumption and low efficiency.

[0050] Specifically, in this embodiment, the solution mainly involves the setup and coordinated use of the base mounting assembly 1, calibration assembly 2, leveling assembly 3, auxiliary bracket assembly 4, and adjustment bracket assembly 5.

The relative positions of the auxiliary bracket assembly 4 and the adjusting bracket assembly 5 are adjusted as needed, and the impeller to be installed is placed between the auxiliary bracket assembly 4 and the adjusting bracket assembly 5.

Simultaneously, the drive motor 502 is used to drive the transmission gear to rotate. The rotation of the gear assembly drives the main slide rod 5011 to move laterally, thereby adjusting the positions of the motor base 5012, the rotary motor 503, and the impeller outer chuck 504.

A locking hole is provided on the upper part of the lower base frame 1021 to cooperate with the locking hole 1013.

[0077] A fixing groove is provided on the outer bottom of the lower frame 1021, and a positioning hole is provided on the inner wall of the fixing groove.

[0078] In this embodiment, during use, the relative position between the upper frame 1011 and the lower frame 1021 can be fixed by inserting a locking pin into the locking hole 1013 and the locking hole;

[0079] In this embodiment, the lower fixed base mechanism 102 and the upper movable base mechanism 101 in the bottom mounting base assembly 1 work together. During use, by controlling the base motor 1022, the upper movable base mechanism 101 and other mechanisms mounted on the upper part of the upper movable base mechanism 101 can be rotated and adjusted, thereby adjusting the usage direction of the assembly device. The ball bearing 1023 and the outer wall of the ball bearing 1023 are fitted and connected to the bottom of the limiting ring plate 1012, which can change the sliding friction between the upper movable base mechanism 101 and the lower fixed base mechanism 102 to rolling friction, thereby greatly reducing the frictional resistance.

[0080] In this embodiment, the fixing groove and positioning hole in the lower frame 1021 facilitate the fixed installation of the component on a base such as a ship.
