Problems solved by technology

Exceeding a measurement of the size of the blades of the wind generators entails, however, a series of collateral problems because of the difficulties that arise both in the transport aspect, due to the existing vehicles and highway traffic regulations, and in the aspect of the actual constructive assembly of the wind generator, due to the types of cranes which must be used.
Indeed, from 35 meters in length onwards, wind generator blades have large transport difficulties, since t

Embodiment Construction

[0027]The object of the invention relates to a system intended to establish the securing for the connection between the sections making up the wind generator blades which are formed by independent longitudinal sections which can be separately transported, for the connection thereof at the constructive assembly site of the application wind generator.

[0028]The system of the invention is provided essentially, but without a limiting character, for blades structurally formed by two outer side skins (3) which are arranged on an inner structure formed by stringers (4) like longitudinal partitions, such that the outer skins (3) determine the aerodynamic profile of the blade, together with a complementary part (5) defining the leading edge, the actual skins (3) forming the trailing edge by means of their prolongation until being connected in this edge, as observed in FIG. 3, whereas the inner stringers (4) form a framework determining, together with the skins (3) a structural box along the f...

Abstract

The invention relates to a system for connecting wind generator blade sections, preferably for the application in the connection of blade sections (1, 2), the formation of which comprises skins (3) determining the outer aerodynamic profile, arranged on inner stringers (4) like longitudinal partitions, the connection between the sections (1, 2) being established by means of rods (12) which are included through holes (8) defined in a longitudinal direction on the inside of the skins (3) and of the stringers (4) in the sections (1, 2), with the threaded connection of said rods (12) at one end on respective elements (11) which are fitted in one of the sections (1) and the tension is tightened by means of corresponding nuts (14) which are incorporated on the other end of said rods in the other section (2).

Description

FIELD OF THE ART [0001]The present invention relates to the wind generator blades which are formed by composition by means of two or more longitudinal sections, for the purpose of facilitating the construction and essentially road transport, proposing a system for connecting sections in the constructive formation of the blades, whereby advantageous features for said function are achieved.STATE OF THE ART [0002]The worldwide demand for renewable energy in order to deal with climate change and maintain an expectation of power production without depending on non-renewable natural resources involves in a very relevant manner wind energy, which is mostly developed by means of wind generators which are driven by a blade rotor capturing the wind.[0003]The development of wind generators and their application to power production by means of using the wind requires, however, wind generators with increasingly greater rated power which are more efficient and have a lower cost per kilowatt of th...
