Problems solved by technology

It can be seen that the on-site hoisting progress and installation period are obviously limited by the local wind conditions
For the construction of wind farms in high-altitude and high-mountain areas, the construction period is more easily affected

Embodiment Construction

[0076] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0077] Please refer to image 3 , image 3 A schematic diagram of a specific embodiment in which the aerodynamic shape adjuster 50 is attached to the outer surface of the enclosure structure provided by the embodiment of the present invention. The enclosure structure is specifically shown as the tower 10 of the wind power generating set in FIG. Other types of enclosure structures will be exemplified later, and for the sake of concise description, the tower 10 is mainly used as an example for illustration below.

[0078] The top of the tower tube 10 in this embodiment is provided with a nacelle 20, and the upwind direction of the nacelle 20 is equipped with a generator and a prime mover. The prime mover is a wind turbine,...

Abstract

The invention discloses an enclosure structure and a pneumatic profile adjuster disposed on the outer surface of the enclosure structure. The pneumatic profile adjuster is of a grid-like structure capable of surrounding the enclosure structure, the grid-like structure includes multiple grid cells, bevel edges are arranged on the at least portion of the grid cells, and the angle of attack changes when fluid passes the bevel edges. The pneumatic profile adjuster changes the pneumatic profile of the fluid, so that the drag coefficient becomes smaller, the pressure difference between the enclosurestructure on the incident flow side and the back side is reduced, and therefore the forward resistance is reduced; and since the drag coefficient becomes smaller, the vortex-induced resonance amplitude in the lateral direction can be reduced, and the vibration is reduced.

Description

technical field [0001] The invention relates to the technical field of enclosure structures, in particular to an enclosure structure and a pneumatic shape adjuster arranged on the outer surface of the enclosure structure. Background technique [0002] Please refer to Picture 1-1 , Picture 1-1 Schematic diagram of wind power generation equipment. [0003] The foundation of the wind power generation equipment is the tower tube 10, which acts as a load bearing and enclosure for the whole machine. As an example, take a circular section tower tube 10 as an example. The tower tube 10 can be a steel tube, or a steel tube and a steel tube. Combination of concrete towers. The tower 10 carries the nacelle 30 , the generator and the impeller 20 of the wind power generation equipment. The wind power generating set that is made up of tower tube 10, impeller 20, nacelle 30 and generator completes the task of obtaining wind energy and converting it into electric energy. The converted ...
