Problems solved by technology

[0004] This situation leads to the continuous improvement of the manufacturing conditions of the integral blade, and the difficulty and cost of manufacturing molds and equipment are getting higher and higher; while the manufacturing and assembly of the combined blade in the past is difficult, the site equipment occupation is the same as that of the integral blade, and the cost is relatively high. High, so not accepted by the market

Abstract

The invention relates to the technical field of wind power blades, and particularly relates to a modular wind power blade and an assembling method thereof. The wind power blade comprises a blade body, a main beam module and a rear edge beam module; the blade body is provided with a suction surface, a pressure surface, a blade root end, a blade tip end, a blade front edge and a blade rear edge; the blade body is divided into a blade root module, a blade middle module and a blade tip module in the length direction of the blade; a first groove and a second groove which extend in the length direction of the blade are formed in the outer surface of the blade root module, the outer surface of the blade middle module and the outer surface of the blade tip module together; the first groove is located in a main beam area of the suction surface and the pressure surface; the main beam module is mounted in the first groove through a bonding or vacuum pouring process; the second groove is located in the blade rear edge and located in the butt joint position of the suction surface and the pressure surface; and the rear edge beam module is mounted in the second groove through a bonding or vacuum pouring process. The wind power blade provided by the invention is convenient to produce in a distributed and automatic mode, easy to assemble and convenient to transport.

Description

technical field [0001] The invention relates to the technical field of wind power blades, in particular to a modular wind power blade and an assembly method thereof. Background technique [0002] The blades of wind turbines are generally integral fiberglass blades. At the same time, there are also some combined blades of different forms at home and abroad. Most of the cases are based on the main beam structure. The shell is split according to different sizes, and then glued Assembled to the main girder in the form of joint or mechanical connection. [0003] With the rise of the megawatt level of generating units and the gradual exhaustion of excellent resources, wind farms are currently expanding from plains to hills, from land to ocean, and the size and weight of blades are also increasing. [0004] This situation leads to the continuous improvement of the manufacturing conditions of the integral blade, and the difficulty and cost of manufacturing molds and equipment are g...
