Problems solved by technology

However, the existing pre-embedded bolts are usually poured and fixed in the blade root, and since the pre-embedded bolts cannot be adjusted in the radial direction, when the diameter enclosed by the threaded holes on the main engine and the diameter enclosed by the pre-embedded bolts cannot Matching, it will not be installed, which brings difficulty to the processing, and the accuracy of the position must be ensured, otherwise it cannot be installed, which makes the assembly flexibility poor and the processing difficult, and it is inconvenient to disassemble and replace the embedded bolts. At the same time, various Bolt-independent radial fine-tuning structure

Abstract

The invention discloses a floating wind power blade with pre-embedded bolts, which includes a blade body, a blade root block, a radial floating mechanism, a radial sliding block, a pre-embedded bolt, and a disassembly fine-tuning mechanism; the disassembly fine-tuning mechanism of the present invention can realize Different degrees of radial fine-tuning of each pre-embedded bolt improves the flexibility of use, and can make each pre-embedded bolt disassembled and replaced, making it more convenient to use.

Description

technical field [0001] The invention relates to a floating type wind power blade disassembled with a pre-embedded bolt. Background technique [0002] Wind turbine blades need to be connected to the host through blade root bolts. There are two main connection methods: T-bolts and embedded bolts. In the early days of the wind power industry, the blade power was small, the blade root load was small, the T-bolt method was used, and the process was simple and the quality was easy to control. With the development of the times, the length and power of the blade have gradually increased, and the disadvantages of this connection method have also emerged. Leaf root removal and perforation produce more solid waste and so on. The pre-embedded bolt connection method can distribute more axial bolts under the same pitch circle diameter, so it can bear a larger load, and the elimination of post-processing drilling links reduces the generation of waste. However, the existing pre-embedded ...
