Description

Technical Field

[0001] This application relates to the technical field of wind power generation, and in particular to a corrugated nacelle cover structure. Background Technology

[0002] Wind power is the world's fastest-growing green energy technology. While onshore wind farms are developing rapidly, people have noticed some limitations to onshore wind energy utilization, such as large land area requirements and noise pollution. Due to the abundant offshore wind energy resources and the feasibility of current technologies, the ocean is poised to become a rapidly developing wind power market.

[0003] Existing wind turbine nacelles are generally made of fiberglass, which is not recyclable and causes significant environmental pollution. In addition, the strong winds at sea can easily damage the nacelles. Once damaged, fiberglass nacelles cannot be repaired in the complex conditions at sea, rendering the entire generator unusable.

[0004] Therefore, there is an urgent need to develop an environmentally friendly and easy-to-maintain cabin cover. Utility Model Content

[0005] The purpose of this application is to provide a corrugated nacelle canopy structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides a corrugated nacelle canopy structure using the following technical solution:

[0007] A corrugated nacelle cover structure includes a frame body, which includes a rear frame, a front frame, a bottom frame, and two symmetrically arranged side frames. The rear frame, front frame, bottom frame, and two symmetrically arranged side frames are all fixed to each other with bolts. The front frame is inclined and has a mounting groove for mounting fan blades in the middle. The bottom frame has a channel groove on the side near the mounting groove and an electrical equipment clearance groove on the side away from the mounting groove.

[0008] Multiple support members are provided between the side frames on both sides;

[0009] The front frame surface is covered with a sealing plate, and the rear frame, bottom frame and two side frames are all covered with corrugated plates.

[0010] The rear frame, front frame, bottom frame, and two side frames are all equipped with several reinforcing ribs.

[0011] Preferably, in order to ensure that the main frame has strong rigidity, the support includes a crossbar, on both sides of which are symmetrically arranged transverse I-beams. One end of the transverse I-beam is fixed to the side frame, and a vertical I-beam is vertically fixed to the bottom of the transverse I-beam. The bottom end of the vertical I-beam is fixed to the bottom frame.

[0012] The horizontal I-beam is symmetrically fixed with stabilizing rods on both sides, and the stabilizing rods, the horizontal I-beam and the side frame form a triangle. The vertical I-beam and the horizontal I-beam are connected by a support rod, and the vertical I-beam, the horizontal I-beam and the support rod form a triangle. The vertical I-beam and the side frame are also braced together by a connecting rod.

[0013] The number of corrugated plates is set to multiple pieces, and the multiple corrugated plates are fixed to the frame body by studs.

[0014] A fiberglass cover is fitted to the top of the main frame.

[0015] In summary, this application includes at least one of the following beneficial technical effects: the corrugated nacelle structure is detachable, facilitating component replacement and improving the service life of the wind turbine. Furthermore, the nacelle uses a frame body combined with corrugated sheet skin, resulting in high overall structural strength. The corrugated sheets are typically installed using studs, a simple and efficient method with a strong connection, effectively transferring wind loads to the frame body, resulting in strong overall wind resistance. The wavy structure of the corrugated sheets increases the moment of inertia of the sheet material, significantly improving its bending resistance, enabling more effective dispersion and bearing of wind pressure, resulting in a more uniform distribution of wind force on the corrugated structure, reducing the impact of localized wind pressure, and further enhancing overall wind resistance.

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] This application discloses a corrugated nacelle canopy structure, referring to... Figure 1-4 The system includes a main frame, which consists of a rear frame 1, a front frame 2, a bottom frame 3, and two symmetrically arranged side frames 4. Each of the rear frame 1, front frame 2, bottom frame 3, and two side frames 4 has several reinforcing ribs. The rear frame 1, front frame 2, bottom frame 3, and two symmetrically arranged side frames 4 are all fixed to each other with bolts. The front frame 2 is inclined and has a mounting groove 22 for mounting the fan blade in the middle. The bottom frame 3 has a channel groove 31 on the side close to the mounting groove 22 and an electrical equipment clearance groove 32 on the side away from the mounting groove 22.

[0023] Multiple support members 5 are provided between the two side frames 4;

[0024] The front frame 2 is covered with a sealing plate 21. The rear frame 1, the bottom frame 3 and the two side frames 4 are all covered with corrugated plates 6. There are multiple corrugated plates 6, which are fixed to the frame body by studs.

[0025] The rear frame 1, bottom frame 3 and two side frames 4 are covered with corrugated plates 6. The wavy structure of the corrugated plates 6 increases the moment of inertia of the plates, which significantly improves their bending resistance. It can more effectively disperse and withstand wind pressure, making the wind force more evenly distributed on the corrugated structure, reducing the impact of local wind pressure, and thus improving the overall wind resistance.

[0026] Reference Figure 3-4 The support member 5 includes a crossbar 51, with transverse I-beams 52 symmetrically arranged on both sides of the crossbar 51. One end of the transverse I-beam 52 is fixed to the side frame 4, and a vertical I-beam 53 is vertically fixed to the bottom of the transverse I-beam 52. The bottom end of the vertical I-beam 53 is fixed to the bottom frame 3.

[0027] To ensure that the support member 5 has good support strength, stabilizing rods 54 are symmetrically fixed on both sides of the transverse I-beam 52. The stabilizing rods 54, the transverse I-beam 52 and the side frame 4 form a triangle. A support rod 55 connects the vertical I-beam 53 and the transverse I-beam 52. The vertical I-beam 53, the transverse I-beam 52 and the support rod 55 form a triangle. A connecting rod 56 is also braced between the vertical I-beam 53 and the side frame 4.

[0028] A fiberglass cover (not shown in the figure) is fitted to the top of the main frame.

[0029] The implementation principle of a corrugated nacelle canopy structure in this application is as follows:

[0030] On the one hand, the nacelle canopy is designed with a frame body and corrugated sheet 6 as the skin, which results in high overall structural strength. The installation of corrugated sheet 6 through studs is usually simple, efficient and secure, and can effectively transfer wind load to the frame body, resulting in strong overall wind resistance. At the same time, the wave-shaped structure of corrugated sheet 6 increases the moment of inertia of the sheet, which significantly improves its bending resistance and can more effectively disperse and bear wind pressure, making the wind force more evenly distributed on the corrugated structure, reducing the impact of local wind pressure, and also improving the overall wind resistance.

[0031] On the other hand, the nacelle cover structure is detachable, which facilitates the replacement of parts and thus can extend the service life of the wind turbine.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
