Description

Technical Field

[0001] The utility model belongs to the field of wind power generation, and particularly relates to a combined structure of a wind turbine impeller and a generator. Background Art

[0002] The country vigorously promotes the development of green energy, making the technology in the field of green power generation advance by leaps and bounds. Due to its relatively high economic benefits, as well as cost and technical factors, large domestic wind power generation devices are all contracted and developed by enterprises and units. However, small and micro wind power generation equipment lags behind in products due to factors such as investment, profit, and efficiency, and cannot meet market demand. A large number of families, units, farms, and breeding farms have no effective means to use wind power generation to help their energy transformation and reduce electricity costs. Therefore, we need to quickly meet market demand, and among them, we need a new type of generator and impeller combined structure to reduce price costs, maintenance costs, transportation and installation costs, and is also green, environmentally friendly, and safe, helping them keep up with the trend of the times and join the construction of green energy faster. Summary of the Invention

[0003] The invention of the utility model overcomes the deficiencies of the existing technology and provides a combined structure of a wind turbine impeller and a generator, which is particularly suitable for batch modular construction. The advantages are that it can reduce the cost of wind turbines, reduce maintenance costs, improve environmental protection and safety, and reduce the risks caused by extreme weather to wind turbines.

[0004] In order to achieve the above advantages, the present invention provides the following technical solutions.

[0005] A combined structure of a wind turbine impeller and a generator includes environmental protection blades, a main shaft, and an axial magnetic field generator. The environmental protection blades are provided with a plurality of connecting platforms and convex platforms. The main shaft is provided with a plurality of mounting platforms and grooves, corresponding to the convex platforms provided on the environmental protection blades respectively. The main shaft and the axial magnetic field generator are an integral structure. The two ends of the main shaft are respectively the axis of the axial magnetic field generator and a reserved mounting hole. The convex platforms are provided with through mounting holes, and the grooves are provided with through mounting holes. The convex platforms of the environmental protection blades are respectively embedded into the corresponding grooves of the main shaft, and screws are used to penetrate the reserved mounting holes of the two, and are locked by nuts.

[0006] Further, there are various combination methods of the axial magnetic field generator and the main shaft, including up and down assembly, embedding, and the main shaft body being the axial magnetic field generator. To clearly demonstrate the novelty of the invention, the description here uses the main shaft body being the axial magnetic field generator for illustration.

[0007] Further, the environmental protection blades are made of recyclable materials, such as ASA, which is softer than the material of the main shaft.

[0008] Further, the main shaft is made of metal, and the axial magnetic field generator inside the main shaft is a multi-layer stacked structure of stator and rotor. The specific structure is not limited and does not affect the present invention.

[0009] Further, the number of environmental protection blades connected to the main shaft is ≥2.

[0010] Further, the installation method of using screws and nuts between the main shaft and the environmental protection blades is only a preferred example, and the installation method is not limited.

[0011] Further, the material of the environmental protection blade is softer than that of the main shaft, and a boss is provided, and the boss serves as a preferred fracture point.

[0012] Further, the space inside the main shaft is sufficient, and a control component, a communication component and a sensing module are provided.

[0013] The beneficial effects of the present invention are as follows.

[0014] Power generation in gentle breeze, convenient transportation, and improved production efficiency.

[0015] By combining the metal main shaft with the soft environmental protection material blades, it can be quickly broken under extreme conditions or abnormal losses to protect the generator body and greatly increase the service life of the generator; the blades are integrally formed by processing with ASA weather-resistant materials, and the cost is greatly reduced compared with the metal blades that account for a high proportion in the market. The production is convenient, and the damaged blades only need to be recycled to the factory for simple reprocessing to achieve recycling. In addition, the transportation cost and loss rate will also be greatly reduced, and the production is more environmentally friendly than metal materials; the main shaft, which is also the generator structure, can make the generator more concise, removing obstacles for future modular dense arrays. The remaining space in the main shaft except for the axial magnetic field motor can be developed for other uses, such as speed change, communication, and sensing modules.

[0016] In addition, the present invention has an echoing effect on the existing patent, the crescent array impeller of the vertical axis wind energy generator (ZL 2022 23009107.1). The special high-pressure air vortex generated around the main shaft by the crescent air guiding angle in the crescent array impeller of the vertical axis wind energy generator can play a great role in quickly cooling the main shaft generator. This technology is beneficial to further improving the efficiency of the generator and opening up a new space for the special mode of typhoon and hurricane generators, while the previous wind turbines had to be shut down in the face of typhoons and hurricanes.

[0021] Figure 4 It is a three-dimensional schematic diagram of the combined structure of the generator and the impeller of a wind turbine.

[0022] As shown in the figure: main shaft 101, axial magnetic field generator 102, mounting table 103, groove 104, environmental protection blade 201, connecting table 202, boss 203, through mounting hole 1011, axial magnetic field generator axis 1012. Specific implementation mode

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention will be further described in detail in combination with the embodiments and the drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. The technical solutions of the present invention will be described in detail below in combination with the embodiments and the drawings, but the protection scope is not limited by this.

[0024] As Figures 1-4 shown, this embodiment provides a combined structure of a wind turbine, including a main shaft 101, an axial magnetic field generator 102, a mounting table 103, a groove 104, an environmental protection blade 201, a connecting table 202, a boss 203, a through mounting hole 1011, and an axial magnetic field generator axis 1012.

[0025] As Figures 1-2 shown, the main shaft 101 is provided with a plurality of mounting tables 103 and grooves 104, and the environmental protection blade 201 is provided with a plurality of connecting tables 202 and bosses 203.

[0026] As Figure 3 shown, the mounting table 103 and the boss 203 are provided with through mounting holes 1011, and six environmental protection blades 201 are installed on the main shaft 101, and screws pass through the through mounting holes 1011 to lock the blades.

[0027] As Figure 4 shown, the main shaft 101 and the axial magnetic field generator 102 are integrated, exposing the axial magnetic field generator axis 1012 and the connecting wires. The installation method of the axis is not limited to hanging installation, base support installation or mixed installation.

[0028] As Figures 1-4As shown, the main shaft is made of metal, preferably aluminum alloy. The environmental protection blade 201 is made of weather-resistant environmental protection plastic or other soft environmental protection materials. In the embodiment, it is preferably ASA. When the combined structure of the wind turbine generator and the impeller encounters hurricanes, extreme weather, etc., the boss 203 of the environmental protection blade will break preferentially, and single or multiple environmental protection blades will fall off, breaking the balance of the wind turbine generator set, causing the generator to decelerate or even stop, effectively protecting the main shaft 101 and the integral axial magnetic field generator 102. The fallen blades are light, with a hollow engineering structure inside, not easy to cause harm, and can be recycled. When maintenance is needed, workers or users only need to carry the replaced environmental protection blade 201 to the site, remove the screws and directly replace it to restore the operation of the wind turbine. The blades are inexpensive and can be prepared at home. The factory can regularly recycle and reshape them. For recycling, users will collect the damaged blades by themselves and wait for the factory to recycle them, bringing a lifetime after-sales experience and being green and environmentally friendly.

[0029] The above content is a further detailed description of the present invention in combination with specific preferred embodiments. It cannot be determined that the specific embodiments of the present invention are limited thereto. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the premise of the present invention, several simple deductions or replacements can still be made, and all should be regarded as belonging to the patent protection scope determined by the claims submitted by the present invention.
