Embodiment 1

[0047] A composite segmented wind turbine blade with high connection strength, such as Figures 1~9As shown, it includes: a blade root segment 1 and a blade tip segment 2, which are spliced ​​to form a blade body; a vertical first web 11 is arranged in the blade root segment 1; a vertical first web 11 is arranged in the blade tip segment 2 The second web 21, after the blade body is formed, the end face of the second web 21 is in contact with the end face of the first web 11; the reinforcing plates 3 are arranged on both sides of the first web 11 and the second web 21; each One end of each reinforcing plate 3 is attached to the side wall of the first web 11 , and the other end is attached to the side wall of the second web 21 ; The top and bottom ends; each connecting plate 4 is "L"-shaped, the two side plates at one end of each connecting plate 4 are respectively fitted with the first web 11 and the inner wall of the blade, and the two side plates at the other end are respecti...

Embodiment 2

[0056] A composite segmented wind turbine blade with high connection strength, such as Figure 5 and Figures 10~15 As shown, the difference from Embodiment 1 is that the end face of one end of the first web 11 is inside the blade root segment 1, and forms an interval with the end face of the blade root segment 1; the end face of one end of the second web 21 extends to the blade root segment 1. Outside the tip section 2; after the blade body is formed, the extended end of the second web 21 extends into the blade root section 1.

[0057] In this embodiment, since the extending end of the second web 21 protrudes into the blade root segment 1, when the blade is subjected to such as Figure 12 When the shown vertical force F2 produces a bending tendency, in addition to the connecting plate 4 being able to rely on the "L"-shaped structure to prevent bending, the second web 21 will also abut against the inner upper end of the blade root segment 1, connecting with the connecting pla...

Abstract

The present invention relates to the technical field of wind power equipment, in particular to a segmented composite wind power blade with high connection strength; it includes a blade root segment and a blade tip segment, which are spliced ​​to form a blade body; the blade root segment is provided with a first a web; a second web is arranged in the blade tip segment; a reinforcing plate is arranged on both sides of the first web and the second web; the two ends of each reinforcing plate are respectively connected to the first web and the second web Plate bonding; connecting plates, set on the top and bottom ends of both sides of the first web and the second web; each connecting plate is "L" shape, and the two side plates at one end of each connecting plate are respectively One web is attached to the blade body, and the two side plates at the other end are respectively attached to the second web and the blade body; the first fastener is used to connect the reinforcement plate, the connecting plate, the first web and the second web ; The second fastener is used to fix the connecting plate and the blade body. The invention provides a segmented composite wind power blade with high connection strength, which improves the connection strength between segments of the composite blade.

Description

technical field [0001] The invention relates to the technical field of wind power equipment, in particular to a composite segmented wind power blade with high connection strength. Background technique [0002] Wind is a pollution-free energy source. For coastal islands, grassland and pastoral areas, mountainous areas and plateau areas that lack water, fuel and transportation, it is very suitable to use wind power according to local conditions. Wind power is an important field for the development of renewable energy. my country is rich in wind energy resources. Accelerating the construction of wind power projects is of great significance for my country to adjust its energy structure and transform its economic development mode. [0003] In traditional wind turbines, in order to make full use of wind energy resources, the length of the blades is set longer. In order to facilitate transportation, the blades are made into segments, and each segment is transported separately, and...
