Embodiment 1

[0026] Such as Figure 1 to Figure 3 As shown, the glue retaining structure for wind turbine blades described in this embodiment is an integral hand-laid-up FRP structure, which includes a structure for blocking and collecting excess structural glue extruded during the process of gluing and mold-fitting wind turbine blades. The sinking platform 1 and the mounting flange sides 2 located on both sides of the sinking platform 1; wherein, the sinking platform 1 is a rectangular sinking platform, and its four sides are respectively designed as inclined surfaces inclined to the inner direction of the sinking platform, and their respective The connection between them is an inverted cone angle connection, and the opposite inclined surfaces on both sides of the sinking platform 1 are symmetrical to each other; the mounting flange side 2 is formed on the two long sides of the above-mentioned rectangular sinking platform, and it is connected with the blade web 3 Blind rivets 5 are used t...

Embodiment 2

[0033] Such as Figure 7 As shown, the difference from Example 1 is that the two short sides of the rectangular sinking platform described in this embodiment are respectively formed with overlapping edges 6. When multiple rectangular sinking platforms are required to collect structural glue, they are installed on two adjacent abdomen Two pairs of rectangular sinking platforms on the board 3 are overlapped by respective overlapping edges 6 .

Abstract

The invention discloses an adhesive-baffling structure for a wind power generator blade. The adhesive-baffling structure is of an integrated structure; the adhesive-baffling structure comprises a sinking table used for baffling and collecting excess structural adhesive extruded in adhesive-applying and die-closing processes of the wind power generator blade, and mounting flange edges positioned on the two sides of the sinking table, wherein the mounting flange edges and adhesive bond flange edges on one side of a blade web are connected through rivets; the adhesive-baffling structure is mounted on the two adhesive bond flange edges at the same side of two adjacent webs in a blade housing through the mounting flange edges on the two sides of the sinking table for filling the gap between the two adhesive bond flange edges. The drop of the adhesive in the inner side of each blade web is fundamentally avoided by the adhesive-baffling structure so as to improve the quality and the property of the blade, reduce the subsequent workload in cleaning the interiors of the blades and lower the costs of manpower and material resources.

Description

technical field [0001] The invention relates to the technical field of cleaning the inner side of the web of a wind power generator blade, in particular to a glue retaining structure for a wind power generator blade. Background technique [0002] After the wind turbine blades are installed and running, as the service life increases, the sundries inside the blade shell become the focus of after-sales maintenance. These sundries not only generate noise, but also cause damage to the whole machine. The small ones will block the water hole of the blade tip, causing the water accumulated in the blade to fail to flow out, and affect the center of gravity and moment during operation; the heavy ones will smash the blade during operation. Damage to the blade, or even smash the cover plate at the root end of the blade, causing fatal damage to the whole machine. Therefore, it is very important to clean up these debris. [0003] The internal cleaning of the blade shell is cumbersome. P...
