[0045] Example 1

[0046] like Figure 1 , Figure 2 and Figure 5 As shown, this utility model embodiment provides a generator set, including a plurality of impeller assemblies 1, a plurality of generator assemblies 2, and a frame structure 3 respectively disposed on the outer periphery of the impeller assemblies 1 and the generator assemblies 2;

[0047] The impeller assembly 1 includes a central shaft 11 rotatably connected to the frame structure 3. A cylindrical main shaft 12 is fixedly arranged on the outer side of the central shaft 11. A plurality of impeller arc blades 13 are evenly arranged on the outer wall of the cylindrical main shaft 12 along its circumference. The inner end of the impeller arc blade 13 is rotatably connected to the cylindrical main shaft 12. The outer end of the impeller arc blade 13 is provided with an outwardly folded impeller arc blade flange 131. The rotation axis of the impeller arc blade 13 is parallel to the axis of the cylindrical main shaft 12. When the impeller arc blade 13 is not working, it covers the cylindrical main shaft 12.

[0048] The generator assembly 2 includes a generator body 21 and a rotating shaft 22. The generator body 21 is fixedly connected to the frame structure 3, and the rotating shaft 22 is rotatably connected to the frame structure 3.

[0049] Along the axial direction of the central shaft 11, the central shaft 11 of several impeller assemblies 1 is fixedly connected to the rotating shaft 22 of several generator assemblies 2;

[0050] Along several planes perpendicular to the central axis 11, two adjacent impeller assemblies 1 are connected by a first synchronous transmission mechanism 14.

[0051] In the specific implementation process, it should be noted that the generator assembly 2 in this utility model embodiment adopts an existing conventional generator, whose structure is well known to those skilled in the art, and will not be described in detail here.

[0052] In addition, such as Figure 1 As shown in the present invention, the plurality of impeller assemblies 1 along the axial direction of the central axis 11 can be one or more, and the plurality of generator assemblies 2 can be one or more; multiple impeller assemblies 1 can be connected to one generator assembly 2, or multiple impeller assemblies 1 can be connected to multiple generator assemblies 2, which is not limited here.

[0053] In the specific implementation process, in order to ensure that the 13-section open position of the impeller's arc-shaped blades can withstand external forces (wind or water force) to the maximum extent, such as Figure 5 As shown, in one possible design, an angle limiting member 15 is provided between the impeller arc blade 13 and the cylindrical main shaft 12 to limit the opening angle of the impeller arc blade 13, thereby ensuring that it can withstand external forces (wind or water force) to the maximum extent.

[0054] Specifically, in this embodiment of the invention, the angle limiting member 15 can be a hinge, that is, the impeller arc-shaped blade 13 and the cylindrical main shaft 12 are rotatably connected by a hinge. The hinge serves as both a connecting member between the impeller arc-shaped blade 13 and the cylindrical main shaft 12, and a limiting member for the opening and closing of the impeller arc-shaped blade 13, which is simple and practical. Of course, the hinge is only one preferred method, and other connection and limiting methods can also be used, such as connecting the impeller arc-shaped blade 13 and the cylindrical main shaft 12 through multiple hinge seats, and then setting several limiting blocks between adjacent hinge seats for angle limiting, etc., which are not limited here.

[0055] In the specific implementation process, in order to ensure that the installation angle of the impeller arc blades 13 on all impeller assemblies 1 in the same plane is consistent, and thus ensure that the impeller assemblies 1 in the same plane are subjected to more uniform force when put into use, in one possible design, the impeller assembly 1 in this embodiment of the present invention is also provided with an angle positioning structure for positioning the installation angle of the impeller arc blades in the same plane.

[0056] By setting an angle positioning structure, not only can the impeller arc blades 13 be installed and positioned quickly and effectively, improving installation efficiency, but also the angle positioning structure ensures that all impeller arc blades 13 on the same plane are in the same position. When subjected to external forces, such as wind force in a certain direction, the windward surface of all impeller arc blades 13 is the same, which can generate greater force and thus improve power generation efficiency.

[0057] Specifically, in this embodiment of the invention, the angle positioning structure may involve setting positioning marks (such as positioning grooves) on the cylindrical main shaft 12 and setting positioning anchors (such as positioning protrusions) at corresponding positions on the first synchronous transmission mechanism 14 to match the positioning marks. When installing the impeller assembly 1, the positioning marks on each cylindrical main shaft 12 are matched and positioned with the corresponding positioning anchors on the first synchronous transmission mechanism 14, thereby ensuring that all impeller arc blades 13 on the same plane are in the same position. Of course, the above method is only one feasible implementation; other angle positioning structures can also be used for angle positioning, and this is not limited here.

[0058] In practical implementation, because external forces in nature are not continuous and stable—for example, wind speeds can fluctuate, and water pressure can suddenly increase under special circumstances—to avoid damage to the impeller's curved blades 13 when external forces change suddenly, especially with a sudden and sharp increase, as... Figure 1 and Figure 5 As shown, in one possible design, the present invention also includes an impeller arc blade brake protector 16 on the impeller assembly 1. By providing the impeller arc blade brake protector 16, when encountering extreme external force changes, the impeller arc blade brake protector 16 will lock the impeller arc blade 13, preventing it from being damaged due to sudden strong external force.

[0059] Specifically, in this embodiment of the present invention, the impeller arc blade brake protector 16 preferably adopts a structural component similar to a motor vehicle seat belt. Its main body is installed on the upper or lower surface of the cylindrical main shaft 12 and is connected to the corresponding impeller arc blade 13 through a protective belt. The working principle of the impeller arc blade brake protector 16 is the same as that of a motor vehicle seat belt. When the external force encountered is within a specified range, the corresponding impeller arc blade 13 opens normally. When the external force suddenly changes, the impeller arc blade brake protector 16 provides braking protection, thereby preventing damage to the impeller arc blade 13. At the same time, under different external force conditions, the impeller arc blade brake protector 16 can also control the opening and closing size of the impeller arc blade 13, that is, it can control the force on the impeller arc blade 13, thereby controlling the rotational speed of the impeller assembly 1.

[0060] In the specific implementation process, in order to reduce the weight of the cylindrical main shaft 12 and improve the utilization efficiency of external forces (wind or water power), such as Figure 5 As shown, in one possible design, the cylindrical main shaft 12 of this embodiment is made of carbon fiber into a cylindrical structure. Carbon fiber has the advantages of high strength and light weight, which can greatly improve the utilization efficiency of external forces (wind or water power). It should be noted that, in addition to carbon fiber, other traditional or new materials can also be used in this embodiment, and no limitation is made here.

[0061] In practical implementation, there are many types of synchronous transmission mechanisms, such as... Figure 1 As shown, in one possible design, the first synchronous transmission mechanism 14 in this embodiment of the present invention adopts a first chain transmission mechanism. Alternatively, a gear transmission mechanism or similar mechanism can be used, as long as synchronous transmission can be achieved; no limitation is made here.

[0062] The generator set provided in this embodiment of the utility model fixes the central shaft of several impeller assemblies along the central shaft axis to the rotating shaft of several generator assemblies; and connects two adjacent impeller assemblies in the same plane perpendicular to the central shaft with a first synchronous transmission mechanism, so that all impeller assemblies and generator assemblies in multiple longitudinal planes and multiple transverse planes form a whole, realizing that multiple generators rotate at the same speed and in the same direction, thereby generating the same amount of electricity, and providing a strong guarantee for stable power output.

[0063] Furthermore, the generator set provided in this embodiment of the present invention designs the impeller arc blades to be rotatably connected to the cylindrical shell. When an external force (such as wind or water) pushes the impeller arc blades on one side of the cylindrical shell to work, the impeller arc blades on that side are in an open state, thereby receiving the push of the external force and driving the entire impeller assembly to rotate. When the impeller arc blades rotate to the other side of the cylindrical shell, due to the rotatable connection, the external force will force the impeller arc blades on that side to adhere to the main shaft surface, eliminating the resistance brought by the non-working impeller arc blades, and improving the energy utilization rate and energy conversion rate.

[0064] Furthermore, in this embodiment of the invention, an outwardly folded flange is provided at the outer end of the impeller arc-shaped blade, making the opening and closing of the impeller arc-shaped blade smoother and more convenient, thereby further improving the conversion efficiency of external force.

[0065] Example 2

[0066] Based on the technical solution of Embodiment 1, this utility model embodiment makes further improvements to the generator assembly 2, as follows:

[0067] like Figures 3-5 As shown in the embodiment of this utility model, support shafts 23 are respectively provided at both ends of the generator body 21. The support shafts 23 and the rotating shaft 22 are coaxially arranged and are rotatably connected to the frame structure 3.

[0068] A cylindrical outer shell 24 is provided on the outer side of the generator body 21. A plurality of generator arc blades 25 are evenly arranged on the circumferential surface of the cylindrical outer shell 24. The inner end of the generator arc blades 25 is rotatably connected to the cylindrical outer shell 24, and the outer end of the generator arc blades 25 is provided with an outwardly folded generator arc blade flange 251. The rotation axis of the generator arc blades 25 is parallel to the axis of the cylindrical outer shell 24. When the generator arc blades 25 are not in operation, they are covered on the cylindrical outer shell 24.

[0069] Along the axial direction of the central shaft 11, the impeller arc blade 13 and the generator arc blade 25 rotate in opposite directions.

[0070] In the specific implementation process, it should be noted that the generator assembly 2 in this embodiment of the present invention also adopts an existing conventional generator, which will not be described in detail here. In this embodiment of the present invention, the support shaft 23 and the cylindrical outer shell 24 can be fixedly connected by welding, bolt connection, snap-fit ​​connection, etc., and there is no limitation here.

[0071] In the specific implementation process, in order to ensure a stable power output, as shown in the figure... Figure 3 and Figure 4 As shown, in one possible design, in this embodiment of the invention, two adjacent cylindrical shells 24 are connected by a second synchronous transmission mechanism 26 in several planes perpendicular to the central axis 11.

[0072] Specifically, in this embodiment of the present invention, the second synchronous transmission mechanism 26 adopts a second chain transmission mechanism. However, other mechanisms, such as gear transmission mechanisms, may also be used; this is not a limitation.

[0073] In the specific implementation process, to ensure that the generator arc-shaped blades 25 on the same plane are subjected to uniform force when put into use, the installation angle of the generator arc-shaped blades on the same plane in this embodiment of the utility model is consistent.

[0074] Specifically, similar to Embodiment 1, an angle positioning mechanism can be provided on the generator assembly 2 for installing and positioning the generator arc blade 25, which will not be described in detail here.

[0075] In the specific implementation process, to avoid damage to the generator's curved blades 25 when external forces change suddenly, especially when they suddenly increase sharply, such as... Figure 3 As shown, in one possible design, the present invention embodiment provides a generator arc-shaped blade brake protector 27 on the generator body 21. The generator arc-shaped blade brake protector 27 in this embodiment is the same as the impeller arc-shaped blade brake protector 16, both employing a structural component similar to a motor vehicle seatbelt, which will not be described further here.

[0076] In specific implementation, to reduce the friction between the rotating shaft 22 and the support shaft 23, and between the support shaft 23 and the frame structure 3, and to improve the utilization efficiency of external forces, in one possible design, an inner bearing is provided on the inner side of the support shaft 23, through which the rotating shaft 22 is rotatably connected to the support shaft 23; an outer bearing is provided on the outer side of the support shaft 23, through which the support shaft 23 is rotatably connected to the frame structure 3. By providing inner and outer bearings, the friction between the rotating shaft 22 and the support shaft 23, and between the support shaft 23 and the frame structure 3, can be greatly reduced, thus improving the utilization efficiency of external forces. The outer circumferential surface of the outer bearing is fixedly connected to the frame structure, preferably by welding.

[0077] In specific implementation, to facilitate the external transmission of electrical energy generated by generator assembly 2, in one possible design, the end of the support shaft 23 away from the frame structure 3 extends into the interior of the cylindrical outer shell 24. An inner slip ring is provided on the portion of the support shaft 23 extending into the cylindrical outer shell 24, and an outer slip ring is provided on the portion outside the cylindrical outer shell 24. The inner and outer slip rings are electrically connected. Specifically, in this embodiment, a wire groove can be formed on the support shaft 23, and wires can be routed between the inner and outer slip rings through the wire groove. The use of the inner and outer slip rings enables convenient and efficient external transmission of electrical energy.

[0078] Example 3

[0079] Based on the technical solutions of Embodiment 1 and / or Embodiment 2, to avoid messy cable laying and subsequent maintenance difficulties, this utility model embodiment further improves upon the design by providing a cable routing channel inside the frame structure 3. Cables are laid within this channel, and all generator components 2 are connected to the outside via these cables. By providing a cable routing channel inside the frame structure 3, the cable laying can be organized, and subsequent maintenance is also facilitated.

[0080] In practical implementation, to save costs, in one possible design, the frame structure 3 in this utility model embodiment is made of tubular material to form a polyhedral frame, and adjacent frame structures 3 are detachably connected. Using tubular material not only saves materials and reduces the overall weight of the generator set, but also eliminates the need for separate wiring channels, making it convenient and quick.

[0081] It should be noted that all the generator sets provided in this utility model embodiment adopt a waterproof structure design, which can be used for both wind power generation and hydropower generation, adapting to local conditions and greatly expanding their application range.

[0082] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
