Technical Field

The invention relates to the technical field of wind power blade forming, in particular to a vein type perfusion connecting pipe and a perfusion method.

Background

At present, in a traditional wind power blade resin adhesive filling system, runners are usually axially laid on the surface of an inner skin, but due to the fact that the number of the axial runners of a large-sized blade is large, the runners are difficult to lay, the distance is not easy to control, quality problems such as air inclusion and the like are easy to form, the runners are mutually independent, the whole filling system needs a large number of adhesive filling ports, multiple operators are needed, the risk of air leakage of an adhesive filling pipe is increased, more adhesive liquid is wasted in the adhesive filling pipe, and when the system is connected with an integrated adhesive filling machine, the connection is more complicated; in addition, due to the negative pressure trend, the glue injection pipe can be opened only when the glue solution completely permeates all cloth layers between the runners and the glue solution exceeds the next runner by 10-20cm, the phenomenon of difficult gluing in a certain area is easily caused, and the pouring time is long.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the vein type injection connecting pipe and the injection method are provided, the injection pipe is arranged in the vein type axial direction and the chord direction, injection is mainly carried out through a chord direction flow passage, the injection time is obviously shortened, the waste of the amount of glue is reduced, and the injection opening is far smaller than that of a traditional injection system.
