However, this method has certain disadvantages: the soft material such as rubber used in the O-ring is a solid material. , so that it cannot be filled by the extruded O-ring, then the resin glue will invade the thread along this gap, causing the seal to fail, which in turn affects the production of embedded blades at the root end

Embodiment 1
[0100] A flange with 92 positioning holes is set on the tooling bracket, and then 92 rubber double O-rings are nested in the first groove on the flange; each rubber double O-ring is connected to the flange Corresponding to the positioning holes, the flange and each rubber double O-ring form a space; among them, the diameter of the outer circle of the flange is 2610mm, and the diameter of the inner circle is 1500mm; 92 positioning holes are evenly distributed near the outer circumference, each The positioning hole is a through hole of Φ38mm, and the distance from the outer circumference is 310mm; the rubber double O-ring includes O-rings with diameters of Φ76mm and Φ56mm;
[0101] In the space enclosed by the flange plate and each rubber double O-ring, apply a resin curing catalyst (a grease-like mixture of DMP-30 type epoxy resin accelerator mixed with YBL005-15W type butter), and then 92 pre-embedded screw sleeves are fixedly connected to the flange through the embedded bolts...

Abstract
The invention provides a blade root end embedding device. The blade root end embedding device comprises a tool support and a flange arranged on the tool support. The flange is provided with a plurality of positioning holes, embedding bolts are arranged in the positioning holes and sleeved with embedding barrels, and the embedding barrels and the flange are connected. Plugs are arranged in the other ends of the embedding barrels. First sealing parts are arranged between the embedding barrels and the flange in a sleeving manner. Each first sealing part comprises two or more sealing pieces, closed space is defined by the flange, the embedding barrels and the first sealing parts, and the closed space is filled with a first resin curing catalyst or a first resin curing retaining agent. The invention provides a production method of a root end embedding blade. A die comprising the blade root end embedding device is utilized for producing the blade, and due to the fact that the blade root end embedding device is good in sealing performance for the front ends of the embedding barrels, non-cured resin intrudes into a threaded connecting part, and the sealing failure frequency of the embedding barrels is low.
Description
technical field [0001] The invention relates to the technical field of wind power blade manufacturing, in particular to a blade root pre-embedded device and a production method of the root pre-embedded blade. Background technique [0002] At present, root-end embedded blades have gradually become the mainstream wind power blades in the market. The characteristic of the root-end embedded blade is that several embedded screw sleeves are evenly distributed on the root end of the blade, and the screw sleeves are embedded in the blade during the production process. Compared with the traditional root-drilled blade, the root-embedded blade has the advantages of high blade root strength and a large number of bolts that can be connected. In the production process of the blade, the mold that matches the production of this type of blade is called the root-end embedded mold. A set of root-end embedded devices in the mold is used to fix the embedded screw sleeve, specifically connected ...
