Embodiment 1

[0026] The vertical infusion process of the slender shell member in the bamboo composite material wind turbine blade of the present invention comprises the following steps:

[0027] a. Select the male mold according to the inner size of the shell to be produced and fix it vertically, remove the sundries on the surface of the mold, and then wipe the surface of the mold with mold cleaner and mold release agent in turn;

[0028] b. Tightly wrap the glass cloth on the surface of the male mold, and tightly wrap the release cloth outside the glass cloth;

[0029] c. Wrap the diversion net on the outside of the release cloth, the upper end of the diversion net is flush with the upper end of the glass cloth, and the lower end of the diversion net is shorter than the lower end of the glass cloth;

[0030] d. Arrange spiral infusion pipelines outside the diversion net;

[0031] e. Paste the sealing tape on the outer upper and lower ends of the male mold where the infusion pipeline is a...

Embodiment 2

[0038] The vertical infusion process of the slender shell member in the bamboo composite material wind turbine blade of the present invention comprises the following steps:

[0039] a. Select the male mold according to the inner size of the shell to be produced and fix it vertically, remove the sundries on the surface of the mold, and then wipe the surface of the mold with mold cleaner and mold release agent in turn;

Abstract

The invention relates to a process for erectly instilling a slender shell element in a blade of a wind turbine with bamboo compound material, which includes a cleaning die, an assembling die, a fixeddie, wrapped glass cloth, wrapped demoulding cloth, wrapped diversion net, a winding spiral pipe, instilling substrate glue material, hardener and demoulding. The erect instilling method solves the instilling problems of one-time forming of the slender shell element in the blade of the wind turbine; at the same time, by using gravity, the glue is uniformly pasted, thus, avoiding glue accumulationcaused by horizontal placement of the instillation, deflection due to male die as well as difficult cloth wrapping and avoids the glue accumulation; the produces has relatively high coaxiality; besides, the inner surface of the products has high precision and the invention is in particular applied to the inner surface of the products with high requirements.

Description

technical field [0001] The invention relates to a production method of a blade prefabricated part in wind power generation equipment, in particular to a vertical infusion process of a slender shell member in a wind turbine blade made of bamboo composite material. Background technique [0002] The method of FRP vacuum bag molding is to pack the laminated product together with the mold tightly with a vacuum bag, and then vacuumize, so that the vacuum bag is closely attached to the surface of the product to achieve the purpose of pressurization. Usually the mold is placed horizontally on the ground, the lay-up material is laid on it, and then the resin is vacuum infused to form. [0003] However, in actual production, there are some product shapes and process requirements that cannot be met by this conventional infusion method. For example, there is a hollow elongated shell part in the blade tip part of the blade, which is used to enhance the strength of the blade tip, and som...
