Abstract

The invention relates to a web, a die used for producing the web, a web production method and a blade. The web comprises more than two support plates which are mutually arranged along a first direction at intervals, each support plate has a first end part and a second end part which are related along a second direction, the first end parts of more than two of the support plates are relatively arranged, and the second end parts are relatively arranged, the web also comprises a shoulder part for connecting the first end parts of more than two of the support plates, wherein the web is arranged ina hollow space and is connected with one of a windward side housing and a lee side housing through the shoulder part, and is connected with the other one of the windward side housing and the lee sidehousing through the second end parts of the more than two of the support plates. When the web is arranged to the blade, is convenient for installation, and can guarantees the production quality and usage life of the blade.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a web, a mold for manufacturing the web, a method for manufacturing the web and blades. Background technique [0002] Wind turbine blades are mainly composed of a shell and a web. The shell is composed of two half shells, namely the windward shell and the leeward shell. The hollow space between the two half shells is in the direction of blade extension. Supported by webs. Therefore, the web is one of the important components of wind turbine blades. Most of the current webs are in the shape of “[”, and a small number of companies have webs in the shape of “I”. With the webs of the above form, when applied to blades, the webs are assembled and used in pairs. [0003] However, due to the limitation of the structural forms of the windward side shell and the back cover shell of the blade shell, when the two paired webs supporting the hollow part are applied to the blade, the pos...
