Description

Technical Field

[0001] This utility model relates to the field of wind turbine technology, and in particular to a wind turbine rotor mounting structure. Background Technology

[0002] A wind turbine is a power generation device that converts wind energy into electrical energy. It is a key piece of equipment for the utilization of clean energy. It mainly consists of a wind turbine, a generator, a control system, and a tower. When wind flows through the wind turbine blades, the blades generate lift due to aerodynamic design and rotate, converting wind energy into mechanical energy. The rotating wind turbine drives the generator through a transmission system, which in turn converts mechanical energy into electrical energy.

[0003] Existing wind turbines typically convert wind energy into electrical energy through rotor blades. However, the rotor blades have a fixed angle, making it impossible to adjust the angle of attack to different wind directions. With varying wind directions, the fixed-angle blades cannot always maintain the optimal orientation to face the wind. When the wind direction changes, the wind energy cannot be fully converted into the rotational kinetic energy of the blades, resulting in a decrease in power generation. Furthermore, the connection between the rotor and the generator lacks sealing protection, allowing rainwater to corrode the internal metal components of the generator, such as windings and bearings. This leads to rust and oxidation, reducing the mechanical strength and electrical conductivity of the components, thus affecting the normal operation of the generator and shortening its service life.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example 1:

[0025] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a wind turbine rotor mounting structure, including a pole 1, a housing 2 fixed to the top of the pole 1, a drive assembly 3 for adjusting the rotor angle inside the housing 2, a generator body 4 on the top of the drive assembly 3, a fixing rod 5 fixed to one end of the generator body 4, a transmission rod 6 fixed to one end of the fixing rod 5 via a flange, sealing rings 7 fixed to the outer sides of both the fixing rod 5 and the transmission rod 6, a first protective shell 8 fixed to the outer sides of both sets of sealing rings 7, a first connecting plate 9 fixed to the outer side of the first protective shell 8, a first hub cover 10 fixed to one end of the transmission rod 6, three sets of mounting brackets 11 installed inside the first hub cover 10, and blades 12 fixed to the outer side of the mounting brackets 11.

[0026] The pole 1 serves as the vertical support for the entire wind turbine, bearing the weight of the upper structure and wind loads to ensure system stability. This is existing technology and will not be elaborated here. The angle of the generator body 4 and blades 12 can be adjusted by the drive component 3 to adapt to different wind speed conditions, reduce wind resistance, and increase wind energy capture efficiency. The generator body 4 has the same structure and working principle as the wind turbine body and generator in application number 202420557550.2. It captures wind energy through the wind turbine and drives the generator inside the generator to rotate and generate electricity. This is existing technology and will not be elaborated here. The sealing ring 7 prevents rainwater and dust from entering the generator body 4. The first protective shell 8 and the second protective shell 16 further protect the sealing ring 7 and the transmission components. The fixing rod 5 and the transmission rod 6 are fixed by a flange, which facilitates the subsequent disassembly and maintenance of the blades 12. The blades 12 capture wind energy and convert it into rotational kinetic energy, which drives the generator inside the generator to rotate and generate electricity.

[0027] The drive assembly 3 includes a drive motor 31 fixed to the inner wall of the housing 2. A first sector gear 32 is fixed to the output end of the drive motor 31, and a second sector gear 33 is meshed with the outer side of the first sector gear 32.

[0028] The drive motor 31 can drive the first sector gear 32 and the second sector gear 33 to rotate, thereby driving the generator body 4 and the blades 12 to rotate laterally, adjusting the relative position of the blades 12 and the wind flow, and increasing the wind energy capture efficiency.

[0029] Example 2:

[0030] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0031] Specifically, the inner ring of the second sector gear 33 is fixed with a rotating rod 13, and the outer side of the rotating rod 13 is rotatably connected to the inner wall of the upright 1. A support rod 14 is fixed to the top of the rotating rod 13.

[0032] The rotation of the second sector gear 33 can drive the rotating rod 13 to rotate inside the upright 1, causing the support rod 14 to drive the support frame 15 and the generator body 4 to rotate, thereby adjusting the wind direction receiving angle of the generator.

[0033] Specifically, the top of the support rod 14 passes through the top of the housing 2 and is fixed with a support frame 15, and the top of the support frame 15 is fixed to the bottom of the power generation equipment body 4 by bolts.

[0034] The support frame 15 secures the generator body 4 with bolts, providing stable support while allowing it to rotate around the axis of the pole 1 to adjust the wind direction.

[0035] Example 3:

[0036] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0037] Specifically, a second protective shell 16 is provided on the top of the first protective shell 8, a second connecting plate 17 is fixed on the outside of the second protective shell 16, and multiple sets of first bolts 18 are threadedly connected to the inner wall of the second connecting plate 17. The first connecting plate 9 and the second connecting plate 17 are fixed by the first bolts 18, and the inner wall of the second protective shell 16 fits with the outer side of the sealing ring 7.

[0038] The second protective shell 16 works in conjunction with the first protective shell 8 to form a closed space, further protecting the sealing ring 7 and the transmission components.

[0039] Specifically, the inner wall of the first hub cover 10 is threaded with three sets of second bolts 19, and the outer side of the second bolts 19 is threaded with two sets of mounting plates 20.

[0040] The two sets of mounting plates 20 are fixed inside the first hub cover 10 by the second bolt 19, which facilitates the subsequent installation and removal of the blades 12.

[0041] Specifically, one end of the second bolt 19 penetrates the inner wall of the mounting bracket 11 and is threadedly connected to the second hub cover 21.

[0042] The second hub cover 21 and the first hub cover 10 form a closed hub structure to protect the internal mounting bracket 11 and the root of the blade 12.

[0043] Specifically, the inner wall of the mounting plate 20 is threaded with multiple sets of third bolts 22, and the mounting bracket 11 is fixed between the two sets of mounting plates 20 by the third bolts 22.

[0044] The mounting bracket 11 is fixed between the two sets of mounting plates 20 by the third bolt 22, which facilitates the installation and disassembly of the mounting bracket 11.

[0045] When in use, as the airflow passes over the blade 12, its curved surface design creates a pressure difference on both sides of the blade 12, generating lift and driving the blade 12 to rotate around the hub. The rotational kinetic energy of the blade 12 is transmitted through the mounting frame 11 to the transmission structure inside the first hub cover 10, and then through the transmission rod 6 and the fixed rod 5 to the generator inside the power generation equipment body 4, ultimately converting it into electrical energy. The drive motor 31 starts and drives the first sector gear 32 to rotate, which in turn drives the second sector gear 33 to rotate in a specific direction. The second sector gear 33 drives the rotating rod 13 to rotate, and through the support rod 14, it drives the support frame 15 and the power generation equipment body 4 to swing laterally, which can optimize the relative position of the blade 12 and the airflow and increase the power generation conversion efficiency. The rotation of the rotating rod 13 synchronously drives the power generation equipment body 4 to rotate around the axis of the upright rod 1, realizing the dynamic adjustment of the wind direction receiving angle. The sealing ring 7 forms the first waterproof and dustproof barrier. The first protective shell 8 and the second protective shell 16 are fastened by the first bolt 18 to form a closed space to further protect the sealing ring 7 and the transmission components.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
