Problems solved by technology

This structure is only suitable for small-diameter thin-walled cylindrical structures, but its technical scalability is poor. Although the eight screw holes are conducive to the radial fastening of the two cylinders, they reduce the structural strength of the cylinder. And it is a great detriment to the smooth aerodynamic shape and sealing advantage of the wedge-ring connection

Embodiment 1

[0036] Embodiment 1 (multi-groove wedge-shaped flange connection structure)

[0037] This embodiment provides a flange structure connected by a wedge ring, which is used for the connection of more than two barrel (pipe) structures. Such as figure 1 , 2 shown, while coordinating image 3 , 4a , 4b, 5a, 5b, 5c, 6a, 6b, and 6c, the multi-groove wedge-shaped flange connection structure using wedge ring connection in this embodiment includes an inner flange 1, an outer flange 2, and a wedge belt 3 (Cooperate image 3 shown) and wedge belt positioning plug 4 (cooperate with Figure 4a , 4b shown).

[0038] The outer surface of the inner flange 1 and the inner surface of the outer flange 2 are correspondingly provided with more than two grooves. The cross-section above is a rectangular wedge groove 5 , and this embodiment takes double grooves as an example for illustration. A wedge belt socket is arranged on the flange, and the wedge belt socket 6 can be on the outer flange ...

Embodiment 2

[0076] Embodiment 2 (directly processing the connection structure of the wedge groove on the cylindrical or tubular structure)

[0077] The wedge ring connection structure of embodiment 1 adopts a flange structure, and the flange structure can connect two cylindrical or tubular structures, and the difference between this embodiment and embodiment 1 is that in the above wedge ring connection structure The rectangular wedge groove can be directly processed on the two cylindrical or tubular structures to be connected. Correspondingly, the wedge belt socket is also directly processed on the cylindrical or tubular structures. Other structures can be analogized by analogy, that is, replace the above-mentioned inner and outer flanges with inner and outer cylinders or inner and outer pipes for mating connection.

Abstract

The invention discloses a structure adopting a wedged ring for connection and a wind turbine generator tower barrel including the same. The structure adopting the wedged ring for connection comprises an inner flange plate, an outer flange plate, a wedged strip and a wedged strip positioning end plug, wherein more than two grooves are correspondingly formed in the outer surface of the inner flange plate and the inner surface of the outer flange plate; when the inner and outer flange plates are in inserted connection, more than two rectangular wedged grooves in parallel are formed in the intersected surface of the two flange plates; a wedged strip slot is formed in the inner flange plate or the outer flange plate; the wedged strip is inserted into the rectangular wedged groove from the wedged strip slot and form interference fit with the rectangular wedged groove; the wedged strip positioning end plug is mounted at the place where the wedged strip slot is. The structure is applicable for connection of cylindrical or tubular structures in various types, can meet with the demands on strong bearing pressure, great bearing load, smooth and neat outer surface, good aerodynamic configuration, high connection reliability and simple mounting operation at the same time. In addition, the inner and outer flange plates can be replaced by inner and outer cylinders or inner and outer tube bodies used for matched connection.

Description

technical field [0001] The invention relates to the connection field of cylindrical or tubular structures, in particular to a structure connected by wedge rings and a wind turbine tower containing the same. Background technique [0002] At present, cylindrical or tubular structures are widely used in civil and military products, such as the connection of oil and gas pipelines, the connection of missile cabins, the connection of wind turbine towers, and the connection of combined wind turbine blades of wind turbines. etc. These connections need to have the requirements of strong bearing pressure, large bearing load, flat and smooth outer surface, good aerodynamic shape, high connection reliability, and simple operation. However, the main methods of cylindrical or tubular connections are screw flanges Methods, direct connection with pipe thread, screw joint, bonding, welding and other methods cannot meet these requirements at the same time.
