Embodiment 1

[0038] The tower tube of this embodiment includes at least one tube section in the height direction, such as figure 2 As shown, each tube section is composed of eight flat-shaped tower tube members 1 sequentially spliced ​​along the circumferential direction, and the cross-section is a regular octagon.

[0039] combine figure 1 As shown, the tower component 1 is specifically a flat plate structure surrounded by an outer facade 11 , an inner facade 12 and two side facades 13 .

[0040] Wherein, the exterior surface 11 is a plane as a whole.

[0041] In order to facilitate splicing between the tower components 1, the angle α between the two side facades 13 of the tower component 1 and the outer facade 11 is an acute angle, that is, gradually shrinks from the outer facade 11 to the inner facade 12 , the specific value of the included angle α is set according to the actual structural design of the barrel section. In this embodiment, the barrel section is made by splicing eight ...

Embodiment 2

[0054] like Figure 4-Figure 6 As shown, compared with Embodiment 1, the main difference of Embodiment 2 is that the wall thickness on both sides of the tower member 1 has not changed relative to the wall thickness of the middle section, and the wall thickness on both sides has not been thickened. The tower member 1 The inner facade 12 is a plane as a whole. This further simplifies the mold design of the tower component 1 and reduces the manufacturing cost of the tower component 1 . Apart from this, the other structures are basically the same, thus possessing all the above-mentioned advantages, which will not be repeated here.

Embodiment 3

[0056] like Figure 7-Figure 9 As shown, compared with Embodiment 1, the main difference of Embodiment 3 is that the shape design of the longitudinal slot groove 131 is different, so the shape of the volume cavity formed by adjacent longitudinal slot grooves is different. In Embodiment 3, the longitudinal slot groove The cross-sectional shape of 131 is semi-elliptical, and the shape of the volume cavity formed is nearly elliptical. Apart from this, the other structures are basically the same, thus possessing all the above-mentioned advantages, which will not be repeated here.

[0057] It is worth noting that the above three embodiments are only partial examples, and are not intended to limit the present invention. Besides the above embodiments, there are other possibilities, such as the number of tower components that make up the tube section may not be limited to the embodiments One to eight in the third embodiment can also be more other possibilities, such as three, four, f...

Abstract

The invention relates to the technical field of wind power generation, and particularly discloses a tower drum and a component thereof. The tower drum component comprises an outer vertical surface, aninner vertical surface and two side vertical surfaces, at least one side vertical surface is provided with a longitudinal seam groove in the height direction, the opening of the longitudinal seam groove is formed in the corresponding side vertical surface, and the length of the opening is not larger than the length of the corresponding side vertical surface. Each drum section of the tower drum isformed by splicing the tower drum components with the same structure, the design of a mold is greatly simplified, and the cost is reduced; and connection and fixation between the tower drum components are realized through the longitudinal seam groove structures, and the connection is safe and reliable. The invention further discloses a wind generating set.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind power generating set, a tower and components thereof. Background technique [0002] Wind power generators are equipment that convert wind energy into electrical energy. Wind energy is a new type of renewable energy with the most mature technology and the most large-scale development in the field of clean energy. With the increasing requirements for environmental protection, wind power technology has developed rapidly. . [0003] The tower is used to support the entire host and is the foundation of the wind turbine. As the key areas of wind power generation shift from the Three North regions to the central and southern regions with low wind speed, in order to make it possible to develop power generation in some low wind speed regions, the application of high towers / ultra-high towers (the super height of the hub exceeds 120 meters) has become unavoidable. Sec...
