Production technology of vane used for vertical shaft wind driven generator

Abstract

The invention discloses a production technology of a vane used for a vertical shaft wind driven generator, comprising the following steps: (1) cleaning a die; (2) applying a mould releasing agent on intracavity surfaces of an upper die and a lower die, and respectively spraying gel coat; (3) respectively paving fiber clothes on intracavity surfaces of the upper die and the lower die, putting at least one inflatable vacuum bag in the intracavity of the lower die, packing the inflatable vacuum bag with diversion nets to separate adjacent vacuum bags, simultaneously, packing a liquid guiding pipe between one diversion net and a vacuum bag, and then packing fiber clothes on the outermost layer of the vacuum bags; (4) carrying out die assembling, sealing the joint of the upper die and the lower die with sealing tapes to seal the intarcavity formed by the upper die and the lower die; (5) arranging an exhaust pipe for exhaust; (6) introducing resin through the liquid guiding pipe, carrying out curing molding, taking out a vane, and taking out the vacuum bags and the liquid guiding pipe from the vane; and (7) arranging end plates at the two sides of the vane. According to the invention, the vane is molded in one body with no environmental pollution, and the production process is simple.

Description

technical field [0001] The invention specifically relates to a manufacturing process of a generator blade, in particular to a manufacturing process of a vertical axis wind power generator blade. Background technique [0002] Composite fan blades are the key moving parts of wind power generation systems, directly affecting the performance of the entire system, and must have weather resistance and reasonable prices for long-term use in outdoor natural environmental conditions. Therefore, the design and manufacturing quality level of the blade is very important, and it is regarded as the key technology and technical level representative of the wind power generation system. [0003] At present, the molding process of composite blades includes wet molding and dry molding. The wet molding includes mold opening molding and mold closing molding, while the dry molding currently only includes mold opening molding. The production process of the mold-opening blade is the traditional ma...

Problems solved by technology

But the production process of the closed mold molding technology at the present stage is complicated, and the investment is relatively large. For example, the Chinese patent application with the patent application number 200510023488.0 uses pre-impregnated fiber cloth, and its process is complicated.

And the patent application number is 200810117093.0 Chinese patent application introduced in the blade integrated molding technology, for the manual pasting system, the quality is not stable

The production process of the above two patents is a wet process. During the wet process, the resin is exposed to the operator and the environment, which is likely to pollute the environment and affect human health.

During the dry process, the resin will not be exposed to the operator and the environment, and has little impact on the environment and human health. However, the current dry process adopts mold opening, and the blades are divided into multiple parts and processed separately. , and then bonded, the integral molding of the blade cannot be realized, and the strength is small
