Description

Technical Field

[0001] The present invention relates to the technical field related to wind power generation, and specifically relates to a wind turbine tower barrel for wind power generation. Background Technique

[0002] The wind turbine tower barrel is the tower pole of wind power generation and mainly plays a supporting role in the wind turbine generator set. During the process of assembling the tower pole using multiple tower barrels, a large crane is required to lift each tower barrel and stack and fix them in sequence. Currently, the fixation between two tower barrels often adopts a bolt fixation method, and in order to ensure the convenience of connection between two tower barrels, reserved holes are often set at the bottom of the tower barrel to facilitate the alignment and connection of the two tower barrels.

[0003] Based on the retrieval of the above information, it can be seen that although the method of using reserved holes provides support for the alignment and connection of the tower barrel, during the hoisting process of the tower barrel, due to the large size and heavy weight of the tower barrel, the alignment adjustment is often not relatively free and convenient, and once there is a hoisting deviation, it is easy to cause damage to the reserved holes or even damage to the tower barrel, resulting in a long time-consuming for the tower pole assembly and high requirements for the hoisting operation. Summary of the Invention

[0004] (1) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the present invention provides a wind turbine tower barrel for wind power generation, which solves the problems of long time consumption and high requirements for hoisting operations when conventional tower barrels are hoisted and assembled into a tower pole.

[0006] (2) Technical Solutions

[0007] To achieve the above object, the present invention provides the following technical solution: A wind turbine tower barrel for wind power generation includes an upper cylinder and a lower cylinder. The upper cylinder and the lower cylinder are fixedly connected through a connecting member. The connecting member includes a circular ring. A plurality of arc-shaped through grooves are opened at the top of the circular ring. The plurality of arc-shaped through grooves are arranged on the circular ring at equal intervals. An arc-shaped driving block is slidably installed inside the arc-shaped through groove. The top and bottom of the arc-shaped driving block are respectively rotatably connected to a linkage plate through a rotating block. One end of the two linkage plates far away from the arc-shaped driving block is respectively rotatably connected to an upper clamping plate and a lower clamping plate through a rotating block. The upper clamping plate and the lower clamping plate are both slidably installed on the side of the arc-shaped through groove far away from the arc-shaped driving block. Specifically, limiting card slots adapted to the upper clamping plate and the lower clamping plate are opened inside the arc-shaped through groove. A first blind hole adapted to the upper clamping plate is opened at the bottom of the upper cylinder, and a second blind hole adapted to the lower clamping plate is opened at the top of the lower cylinder. The upper clamping plate and the upper cylinder, and the lower cylinder and the lower clamping plate are both fixedly connected through a first fastening bolt.
