Embodiment Construction

[0009] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0010] Depend on figure 1 It can be seen that the present invention includes: a root-end structure lay-up 1; a diversion net 2 is arranged at the front end of the root-end structure lay-up 1, and a resin diversion pipe 3 is placed on the upper front end of the diversion net 2; it also includes: A breathable isolation film 4; said breathable isolation film 4 is covered on the guide net 2, and between the outlet of the resin guide pipe 3 to the front side of the root-end structural layup 1; a vacuum pumping mechanism 5 ; The root-end structure lay-up 1 , guide net 2 , resin guide tube 3 and breathable isolation membrane 4 are in the vacuum pumping mechanism 5 .

[0011] The working process of the present invention is: after the perfusion starts, the resin first starts to flow in the diversion tube, and flows into the root-end structure layer thro...

Abstract

The invention relates to a blade root end pouring device for a wind mill, which comprises a root end structural laying layer, an air pervious isolating film and a vacuum pumping mechanism, wherein a guide net is arranged at the front end of the root end structural laying layer and a resin draft tube is arranged at the upper part at the upper front end of the guide net. The air pervious isolating film is covered on the guide net and between the outlet of the resin draft tube and the front side adjacent to the root end structural laying layer; and the root end structural laying layer, the guide net, the resin draft tube and the air pervious isolating film are arranged in the vacuum pumping mechanism. The device has the advantages that because the auxiliary air extracting mode of the air pervious film is added to a guide layer, residual air bubbles clamped in resin are eliminated so that the compactness of the products is improved, the resin is poured more completely, and the product quality is improved. Moreover, because an integral structural plane is exhausted, the pouring speed and the quality stability can be effectively improved.

Description

technical field [0001] The invention relates to a filling device, in particular to a filling device for the root end of a wind turbine blade. Background technique [0002] The root end of the fan blade is a pure glass steel structure layer with a thickness of 90mm to 100mm. [0003] The technology used in the prior art makes the whole infusion process take a long time, the technology is difficult, and the control parameters are complicated. The reason is that there are residual air bubbles in the resin, which are easily mixed in the structural layer and cause defects. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a wind turbine blade root irrigation device, which aims to solve the above-mentioned problems. [0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: [0006] The present invention includes: a root-end structure layup; a d...
