Problems solved by technology

[0002] At present, the traditional resin glue infusion system for wind power blades usually lays the flow channels axially on the surface of the inner skin. However, due to the large number of axial flow channels in large blades, it is difficult to lay the flow channels, and the spacing is not easy to control, which is easy to form air pockets. and other quality problems, and the flow channels are independent of each other, the entire perfusion system requires a lot of injection ports, and requires multiple operators, the risk of air leakage in the injection tube increases, and the waste of glue in the injection tube is relatively large More, when connecting with the integrated glue filling machine, the connection is more cumbersome; in addition, due to the direction of negative pressure, the glue injection pipe must completely soak all the cloth layers between the flow channels with the glue liquid and the glue liquid exceeds the next flow channel by 10-20cm It can only be opened, and it is easy to cause difficulty in gluing in a certain area, resulting in a long time-consuming perfusion

Embodiment 1

[0028] Embodiment 1, the present invention provides a vein type perfusion joint, such as figure 2 As shown, it includes the injection port 1, the buffer channel 2, the main channel 3, the secondary channel 4 and the plastic outlet 5 in sequence. The buffer channel 2 is between the injection port 1 and the main channel 3, and the secondary channel 4 is a leaf vein. Distributed and connected to the main flow channel 3, the end of the main flow channel 3 is provided with a glue outlet 5, and the glue injection port 1, the buffer channel 2, the main flow channel 3, the secondary flow channel 4 and the glue outlet 5 are all passed through a steel wire spiral tube 6 is connected, and the end of the glue outlet 5 is connected to the integrated gluer 15.

[0029] The glue injection port 1 includes a first pipeline 7, the number of the first pipeline 7 is more than two, and a plurality of first pipelines 7 are connected sequentially through the steel wire spiral tube 6, as image 3 A...

Embodiment 2

[0043] In the second embodiment, the main channel 3 can be appropriately increased according to the demand. In this embodiment, the number of the main channel 3 is more than two, and it is connected with the steel wire spiral tube 6 through the green head 16, such as figure 1 As shown, each main channel 3 is provided with a glue injection port 1 . When the perfusion product has a large area corner and the cloth layer is thick, it is easy to produce a perfusion partition, and the main channel 3 can be appropriately added in this area to supply glue, and the secondary channel 4 is adjusted according to the number of the main channel 3, and the rest is the same as the embodiment one.

Embodiment 3

[0044] Embodiment 3, the vein-type joint is not limited to the production of wind power blade glue filling, but also can be used in the production of other pouring products, such as blade prefabricated parts, root tiles, webs, etc., and the rest are the same as Embodiments 1 and 2.

[0045] The PPR pipe (DN25) 12 and the PPR pipe (DN20) 13 are PPR pipes 8 with outer diameters of 25 and 20 mm.

Abstract

The invention discloses a vein type perfusion adapter tube and a perfusion method. The vein type perfusion adapter tube sequentially comprises a glue perfusion opening, a buffer channel, a main flow channel, secondary flow channels and a glue outlet; the buffer channel is arranged between the glue perfusion opening and the main flow channel; the secondary flow channels are distributed in a vein form and connected to the main flow channel; the tail of the main flow channel is provided with the glue outlet; and the glue perfusion opening, the buffer channel, the main flow channel, the secondaryflow channels and the glue outlet are all connected through steel wire spiral tubes. According to the vein type perfusion adapter tube disclosed by the invention, by virtue of a vein type shaft and aglue perfusion tube which is arranged chordwise, the glue is mainly injected through a chordwise flow channel so that the perfusion time is obviously reduced; waste of glue is reduced; and the vein type perfusion adapter tube has less the glue perfusion openings than a traditional perfusion system.
