Problems solved by technology

This method has high requirements on the bonding process, and the quality control is difficult. In the case of bonding defects between the two half-shells, it is easy to crack and damage the bonding surface between the half-shells and the half-shells during the operation of the fan. The blade and the whole machine pose a fatal risk

Embodiment Construction

[0021] The present invention will be further described below in conjunction with specific examples.

[0022] see Figure 2 to Figure 7 As shown, the airbag-type wind turbine blade structure provided in this embodiment includes a structural skeleton and multiple sets of blade body airbags. The main girder 14 on the windward side, the main girder 16 on the leeward side and the airbag installation flange 15 are composed. Formed by the bonding process, it plays the role of anti-shearing during the operation of the entire wind power blade. The main beam 14 on the windward side and the main beam 16 on the leeward side are the main load-bearing structures of the entire structural skeleton, and are respectively connected to the tip of the blade through a vacuum infusion process. The windward side and the leeward side of the section shell 11 and the blade root section shell 12 are integrally formed, and a section of main beam is reserved between the blade tip section shell 11 and the ...

Abstract

The invention discloses an air bag type wind power blade structure. The structure comprises a structural skeleton and blade airbags, the structural skeleton comprises a blade tip segment shell, a blade root segment shell, a box web, a main beam (a windward surface and a leeward surface) and an airbag installing flange, the box web and the main beam (the windward surface and the leeward surface) are respectively formed with the windward and leeward surfaces of the blade tip and root segment shells, a main beam section is reserved between the blade tip and root segment shells, the airbag installing flange is distributed on the main beam section, bolt holes are formed in both sides of each airbag installing flange, bolt holes are formed in the sides, facing the airbag installing flange, of the blade tip and root segment shells, and a set of the blade airbags are respectively installed between the adjacent airbag installing flanges and between the blade tip and root segment shells and theadjacent airbag installing flange by screws. The structure uses an inflatable airbag to replace a blade body structure of a blade, the whole installation and disassembly process is convenient, and more convenience is brought for the subsequent maintenance of the blade.

Description

technical field [0001] The invention relates to the technical field of renewable new energy wind power generation blades, in particular to an airbag type wind power blade structure. Background technique [0002] With the development of the wind power industry, the megawatt level of the complete machine has also risen with the tide, and the wind power blades are getting bigger and longer. The resulting difficulties are that the difficulty of blade production is greatly increased, the difficulty of process control in the production process is greatly increased, and the difficulty of blade maintenance is greatly increased. [0003] The structure of the traditional blade is as figure 1 shown. Its main structure includes the windward shell 01, the leeward shell 02, and the web 03 (front and rear edge webs). The windward side and the leeward side are a sandwich structure composed of inner and outer skin 04, core material 05, main beam 06, trailing edge beam (not shown in the fi...
