Embodiment 1

[0028] Embodiment 1: Prepare a 60m-high conical tower, which is formed by connecting 3 sections

[0029] Such as figure 1 As shown, the skin 1 and 25 stringers 2 are formed by co-curing, the 25 stringers 2 are evenly distributed on the inner surface of the skin 1, and the ordinary partition frames 3 are evenly distributed along the height direction of the tower and perpendicular to the stringer 2 Install. The long stringer 2 is "Ω" shape, and the bulkhead 3 is "C" shape.

[0030] Such as figure 2 As shown in , the mold 4 has 25 evenly distributed "Ω"-shaped grooves 5, and the rotating shaft 6 of the mold 4 can rotate and move axially. The raw materials are: glass fiber, epoxy resin, PVC foam, quartz sand. The common partition frame 3 is pre-prepared by a compression molding process. The connection frame 9 is made of metal materials, as shown in FIG. 5 .

[0031] The preparation method comprises the following steps:

[0032] 1) Co-cure stringer 2 and skin 1. In the "Ω"...

Embodiment 2

[0036] Prepare a 100m-high conical tower, which is connected by 5 sections. The difference from Example 1 is that the skin 1 is reinforced by mixing glass fiber and carbon fiber, the stringer core of the stringer 2 is made of balsa wood, and the ordinary frame 3 is made of "L" shaped frame.

Abstract

The invention relates to a composite material tower drum of a wind driven generator as well as a preparation method and a preparation mold of the composite material tower drum. The composite material tower drum adopts a tapered tubular structure, and comprises a covering 1, long purlins 2 and ordinary partition frames 3, wherein the long purlins 2 are distributed on the circumference of the wall of the tower drum at a certain distance, fixed on the inner diameter of a tower drum support formed by the purlins 2 through the ordinary partition frames 3 and covered with the covering 1 on the outer diameter of the tower drum support formed by the purlins 2; and the ordinary partition frames 3 are distributed axially on the tower drum at a certain distance. At the same time, segmented tower drums can be connected by connection frames 9 according to the actual use requirement of the tower drum of the wind driven generator. The tower drum is made of a composite material, the anti-corrosion problem of the tower drum is completely solved, and the maintenance cost of the tower drum is greatly reduced; the composite material tower drum of the wind driven generator has the characteristic of light weight, and the transport and mounting cost of the tower drum is reduced; and besides, the composite material tower drum can be manufactured on the spot, the manufacturing cost is reduced, hereby manufacturing equipment is assembled in a standard truck and a container, and the transportation cost is reduced.

Description

technical field [0001] The invention relates to a wind power generator tower, in particular to a composite material tower of a wind power generator, a preparation method thereof, and a preparation mold. Background technique [0002] A wind turbine is mainly composed of a wind turbine host, blades, and a tower. For the tower tube of a large wind turbine, it is usually made of steel, and the outer surface is sprayed with anti-corrosion treatment. After several years of on-site operation, the paint on the surface of the frame tube will peel off, causing the tower shell to rust. Generally, the design and service life of wind turbines are 20 years. Therefore, within the service life, it is necessary to clean the surface of the tower tube many times. Anti-corrosion treatment such as rust and paint repair, due to the height of the tower of the wind turbine, the cost of anti-corrosion maintenance is very expensive. In addition, the development of wind turbines toward larger power ...
