Problems solved by technology

[0003] However, the existing nacelle covers of wind turbines have the following disadvantages: 1) The reinforcing ribs are long strips of polyurethane foam, and there are many positioning data points, and the positioning deviation of the reinforcing ribs is large, and the laying of the reinforcing ribs is time-consuming and labor-intensive
2) After the reinforcing ribs are laid, 4 layers of glass fiber cloth must be laid on the upper side of the reinforcing ribs for reinforcement. It is difficult to lay layers at the crossing positions of the reinforcing ribs, and the whole reinforcement laying process is also time-consuming and labor-intensive.
3) Subsequent operations may easily cause misalignment of the laid reinforcement ribs, and it is difficult to repair if the misalignment problem is found after the product is formed
4) All reinforcement ribs are arranged on the inner surface of the product. The reinforcement ribs are higher than the inner surface of the product. The bottom surface of the reinforcement ribs and the main body of the cabin cover form a corner of about 120°. The corner position is likely to cause resin accumulation during the vacuum infusion molding process of the product, forming The quality of rich resin is defective, and the follow-up needs to be polished and refined, which is time-consuming and laborious; 5) The overall ventilation and cooling, dustproof and waterproof effects of the cabin cover are not good, and need to be further improved
[0004] The structure of the nacelle cover of the existing wind turbine is not reasonable enough, it is not easy to process, the production is time-consuming and laborious, and the ventilation and cooling and dustproof and waterproof effects are not good

Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] Such as Figure 1-4 As shown, a nacelle cover of a wind turbine includes a nacelle body. The front end of the nacelle body is provided with a rotor locking disk 5, and the bottom end of the front part of the nacelle body is provided with a tower installation port 4. The nacelle body includes The left engine room lower body 3, the right engine room lower body 2 connected to the right side of the left engine room lower body 3 by bolts and the engine room upper cover 1 connected to the right engine room lower body 2 and the left engine room lower body 3 by bolts, the left engine room lower body 3, and the right engine room lower body 2 And the cabin loam cake 1 is all made of the PVC outline plate 21 that is provided with some through holes, the inner glass steel layer 22 that is formed on the inner layer of the PVC outline plate 21, the outer glass fiber reinfor...

Abstract

The invention discloses a nacelle cover of a wind turbine and a processing method thereof. The nacelle cover of the wind turbine comprises a nacelle cover body, wherein the front end of the nacelle cover body is provided with a rotor locking disc opening; the bottom end of the front part of the nacelle cover body is provided with a tower cylinder mounting opening; the nacelle cover body comprisesa left nacelle lower body, a right nacelle lower body connected to the right side of the left nacelle lower body through bolts and an nacelle upper cover connected above the right nacelle lower body and the left nacelle lower body through bolts; and the left nacelle lower body, the right nacelle lower body and the nacelle upper cover are each composed of a PVC contour plate with a plurality of through holes, an inner glass fiber reinforced plastic layer formed on the inner layer of the PVC contour plate, an outer glass fiber reinforced plastic layer formed on the outer layer of the PVC contourplate, and unsaturated polyester resin columns formed in the through holes of the PVC contour plate. The nacelle cover is more reasonable in structure and easier to process, and the ventilation cooling and dustproof waterproof effect is better by additionally arranging a ventilation cooling and dustproof waterproof structure.

Description

technical field [0001] The invention relates to the technical field of wind power generators, in particular to a nacelle cover of a wind power generator and a processing method thereof. Background technique [0002] In the prior art, the nacelle cover of the wind turbine is supported and strengthened by a plurality of herringbone-like polyurethane foam ribs arranged horizontally and vertically. [0003] However, the existing nacelle covers of wind turbines have the following disadvantages: 1) The reinforcing ribs are long strips of polyurethane foam, so there are many positioning data points and the positioning deviation of the reinforcing ribs is large, and the laying of the reinforcing ribs is time-consuming and labor-intensive. 2) After the reinforcing ribs are laid, 4 layers of glass fiber cloth must be laid on the upper side of the reinforcing ribs for reinforcement. It is difficult to lay layers at the crossing positions of the reinforcing ribs, and the whole reinforce...
