Description

Technical Field

[0001] This utility model relates to the field of impeller technology, specifically to an impeller, an impeller frame structure, a generator rotating structure, and a generator frame structure. Background Technology

[0002] In the prior art, blades are uniformly and fixedly distributed along the rotation axis. When the blades on one side of the main shaft do work under the action of external force, the non-working blades on the other side of the main shaft are symmetrically arranged with the working blades. The non-working blades also bear the force of the external force. The non-working blades also bear a part of the force, which cancels out the work efficiency of the working blades. In other words, while the working blades are doing work, part of the power is used to counteract the resistance brought by the non-working blades on the other side of the main shaft, thereby reducing the work efficiency of the working blades. Utility Model Content

[0003] The purpose of this invention is to provide an impeller, an impeller frame structure, a generator rotating structure, and a generator frame structure to solve at least one of the aforementioned problems in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An impeller includes a cylindrical main shaft with a plurality of circumferentially uniformly arranged arc-shaped blades. The inner ends of the arc-shaped blades are rotatably connected to the cylindrical main shaft, and the rotation axis of the arc-shaped blades is parallel to the axis of the cylindrical main shaft. When not in operation, the arc-shaped blades cover the cylindrical main shaft, and the outer ends of the arc-shaped blades are provided with outwardly folded impeller flanges.

[0006] In this technical solution, the impeller's arc-shaped blades are wrapped around the cylindrical main shaft when not in operation. That is, the arc of the impeller's arc-shaped blades matches the arc of the cylindrical main shaft, so that the impeller's arc-shaped blades can wrap around and fit the cylindrical main shaft when not in operation. In actual operation, since the inner end of the impeller's arc-shaped blades is rotatably connected to the cylindrical main shaft, and the rotation axis of the impeller's arc-shaped blades is parallel to the axis of the cylindrical main shaft, and the outer end of the impeller's arc-shaped blades is provided with an outward-folding impeller flange, the impeller flange facing the wind direction will drive the corresponding impeller's arc-shaped blades to rotate with the wind, opening the impeller's arc-shaped blades. After the impeller's arc-shaped blades are opened, they drive the rotation of the cylindrical main shaft under the action of wind or water. During the rotation of the cylindrical main shaft, when the working impeller's arc-shaped blades rotate to the point where their back faces the wind or water direction, the wind or water will drive the impeller's arc-shaped blades to rotate in the opposite direction until they cover and adhere to the cylindrical main shaft. Each impeller's arc-shaped blade performs the above actions in sequence, thereby driving the continuous rotation of the cylindrical main shaft.

[0007] In summary, this technical solution utilizes wind or water power to drive the impeller's flanges, causing the impeller's curved blades to open. This allows the curved blades to then withstand the force of wind or water, enabling them to perform work. This, in turn, drives the cylindrical main shaft to rotate continuously. Simultaneously, when the curved blades rotate to a non-working position, they can wrap around and adhere to the cylindrical main shaft. The impeller exhibits an asymmetrical state during operation, eliminating the resistance caused by wind or water power when the curved blades are not in a working position. This improves the blades' work efficiency, reduces the pressure on the cylindrical main shaft from the force driving the curved blades, thereby reducing the pressure on the main shaft bearing, extending its service life, saving on impeller operating costs and maintenance frequency, and improving energy conversion efficiency.

[0008] Furthermore, in order to better drive the impeller's arc-shaped blades, the angle between the impeller flange and the outer surface of the impeller's arc-shaped blades is an obtuse angle.

[0009] Furthermore, in order to limit the maximum opening and closing angle of the arc-shaped blades, a limiting member is provided between the cylindrical main shaft and the arc-shaped blades of the impeller. The limiting member is used to limit the rotation angle of the arc-shaped blades of the impeller.

[0010] Furthermore, the inner end of the impeller's arc-shaped blade is rotatably connected to the cylindrical main shaft via a hinge, which can limit the maximum opening angle of the impeller's arc-shaped blade.

[0011] Furthermore, in order to better drive the cylindrical spindle, the cylindrical spindle is a hollow cylindrical structure.

[0012] This utility model also provides an impeller frame structure, which includes the aforementioned impeller, a central shaft, and an impeller frame. The cylindrical main shaft is coaxially and fixedly connected to the central shaft, and the central shaft is rotatably connected to the impeller frame.

[0013] This utility model also provides a generator rotating structure, which includes a generator frame, a generator shaft, a generator housing, and an impeller frame structure as described above. The two ends of the generator shaft are rotatably connected to the generator frame. The generator shaft and the generator housing are rotatably connected. The generator housing is a cylindrical shell. Multiple generator arc-shaped blades are evenly arranged circumferentially on the cylindrical shell. The inner ends of the generator arc-shaped blades are rotatably connected to the cylindrical shell. The rotation axis of the generator arc-shaped blades is parallel to the axis of the cylindrical shell. When not in operation, the generator arc-shaped blades are covered by the cylindrical shell. The outer ends of the generator arc-shaped blades have outwardly folded generator flanges. The impeller frame is fixedly mounted on the generator frame. The lower connecting end of the central shaft is fixedly connected to the upper connecting end of the generator shaft. The rotation directions of the impeller arc-shaped blades and the generator arc-shaped blades are opposite.

[0014] Furthermore, a limiting member is provided between the cylindrical outer shell and the arc-shaped blades of the generator, the limiting member being used to limit the rotation angle of the arc-shaped blades of the generator.

[0015] Furthermore, in order to achieve power output, an inner slip ring and an outer slip ring are included. The inner slip ring is installed on the generator shaft located inside the generator housing, and the outer slip ring is installed on the generator shaft located outside the generator housing. A cable connects the inner slip ring and the outer slip ring.

[0016] This utility model also provides a generator frame structure, characterized in that: it includes a generator, a generator frame, and an impeller frame structure as described above. The generator includes a generator housing and a generator shaft. The generator housing is fixedly connected to the generator frame, the generator shaft is rotatably connected to the generator frame, the impeller frame is fixedly mounted on the generator frame, and the lower connecting end of the central shaft is fixedly connected to the upper connecting end of the generator shaft.

[0017] The beneficial effects of this utility model are as follows: In this technical solution, the impeller arc blades are wrapped around the cylindrical main shaft when they are not in operation, that is, the arc of the impeller arc blades matches the arc of the cylindrical main shaft, so that the impeller arc blades can wrap around and fit the cylindrical main shaft when they are not in operation. In actual operation, since the inner end of the impeller's arc-shaped blades is rotatably connected to the cylindrical main shaft, and the rotation axis of the impeller's arc-shaped blades is parallel to the axis of the cylindrical main shaft, and the outer end of the impeller's arc-shaped blades is provided with an outward-folding impeller flange, the impeller flange facing the wind direction will drive the corresponding impeller's arc-shaped blades to rotate with the wind, opening the impeller's arc-shaped blades. After the impeller's arc-shaped blades are opened, they drive the rotation of the cylindrical main shaft under the action of wind or water. During the rotation of the cylindrical main shaft, when the working impeller's arc-shaped blades rotate to the point where their back faces the wind or water direction, the wind or water will drive the impeller's arc-shaped blades to rotate in the opposite direction until they cover and adhere to the cylindrical main shaft. Each impeller's arc-shaped blade performs the above actions in sequence, thereby driving the continuous rotation of the cylindrical main shaft.

[0018] In summary, this technical solution utilizes wind or water power to drive the impeller's flanges, causing the impeller's curved blades to open. This allows the curved blades to then withstand the force of wind or water, enabling them to perform work. This, in turn, drives the cylindrical main shaft to rotate continuously. Simultaneously, when the curved blades rotate to a non-working position, they can wrap around and adhere to the cylindrical main shaft. The impeller exhibits an asymmetrical state during operation, eliminating the resistance caused by wind or water power when the curved blades are not in a working position. This improves the blades' work efficiency, reduces the pressure on the cylindrical main shaft from the force driving the curved blades, thereby reducing the pressure on the main shaft bearing, extending its service life, saving on impeller operating costs and maintenance frequency, and improving energy conversion efficiency.

[0036] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0037] Example 1:

[0038] like Figures 1-16 As shown, this embodiment provides an impeller, including a cylindrical main shaft 1. A plurality of arc-shaped impeller blades 2 are evenly arranged circumferentially on the cylindrical main shaft 1. The inner ends of the arc-shaped impeller blades 2 are rotatably connected to the cylindrical main shaft 1. The rotation axis of the arc-shaped impeller blades 2 is parallel to the axis of the cylindrical main shaft 1. Figure 1 As shown, the impeller arc blade 2 is wrapped around the cylindrical main shaft 1 when it is not in operation, and the outer end of the impeller arc blade 2 is provided with an outwardly folded impeller flange 3.

[0039] In this technical solution, the impeller arc blade 2 is wrapped around the cylindrical main shaft 1 when it is not in operation. That is, the arc of the impeller arc blade 2 is matched with the arc of the cylindrical main shaft 1, so that the impeller arc blade 2 can wrap around and fit the cylindrical main shaft 1 when it is not in operation. In actual operation, since the inner end of the impeller arc blade 2 is rotatably connected to the cylindrical main shaft 1, and the rotation axis of the impeller arc blade 2 is parallel to the axis of the cylindrical main shaft 1, and the outer end of the impeller arc blade 2 is provided with an outwardly folded impeller flange 3, the impeller flange 3 facing the wind direction will drive the corresponding impeller arc blade 2 to rotate with the wind, opening the impeller arc blade 2. After the impeller arc blade 2 is opened, it drives the rotation of the cylindrical main shaft 1 under the action of wind or water. During the rotation of the cylindrical main shaft 1, when the working impeller arc blade 2 rotates to the point where its back is facing the wind or water direction, the wind or water will drive the impeller arc blade 2 to rotate in the opposite direction until it covers and adheres to the cylindrical main shaft 1. Each impeller arc blade 2 performs the above actions in sequence, thereby driving the continuous rotation of the cylindrical main shaft 1.

[0040] In summary, this technical solution, through the driving force of wind or water power on the impeller flange 3, causes the impeller arc blades 2 to be in an open state, thus allowing the impeller arc blades 2 to be pushed by wind or water power, enabling the impeller arc blades 2 to start doing work. This, in turn, drives the cylindrical main shaft 1 to rotate continuously. At the same time, when the impeller arc blades 2 rotate to a non-working position (with the back of the impeller arc blades facing the direction of wind or water power), they can cover and fit against the cylindrical main shaft 1. The impeller presents an asymmetrical state in the working state, eliminating the resistance caused by the non-working impeller arc blades 2 facing the wind or water power, improving the working efficiency of the blades, reducing the pressure of the force used to drive the impeller arc blades 2 to do work on the cylindrical main shaft 1, thereby reducing the pressure on the main shaft bearing, increasing the service life of the bearing, saving impeller operating costs and maintenance frequency, and improving energy conversion rate.

[0041] Specifically, such as Figure 2-4 As shown, the motion states of multiple impeller arc blades 2 during impeller rotation are illustrated. There are three impeller arc blades 2: a first impeller arc blade 2.1, a second impeller arc blade 2.2, and a third impeller arc blade 2.3. When the first impeller arc blade 2.1, the second impeller arc blade 2.2, and the third impeller arc blade 2.3 are subjected to wind or water force, the cylindrical main shaft 1 will rotate counterclockwise as the first impeller arc blade 2.1, the second impeller arc blade 2.2, and the third impeller arc blade 2.3 are opened sequentially.

[0042] like Figure 8 As shown, in specific implementation, the impeller can be installed on a conventional generator 22, and the generator 22 can be set on land for use as a wind turbine, or it can be set in flowing water for use as a hydroelectric generator. The generator 22 is installed on a base 4, which can be fixedly connected to the ground or the bottom of the water. Preferably, the foundation pit is poured with reinforced concrete, and a long steel rod is used to pass through the pre-set through hole of the base and drive it into the ground to fix the connection between the base and the ground, stabilize the base, and enable the base to withstand greater wind or water force, so as to keep the generator 22 and its impeller stable and safe to operate.

[0043] Specifically, the base 4 can be designed with a hollow cavity to reduce its weight and facilitate transportation. To increase the weight of the base 4, after it is fixed to the ground, sand or water can be injected into the cavity to increase its weight and make the base 4 more stable.

[0044] In practical applications, the abundant wind energy resources of the ocean can be used to generate electricity. The generator 22 is installed on the base 4, which has a sealed cavity, so that the generator with the impeller can float on the sea surface. In order to stabilize the base 4, the anchor chain is used to fix the base 4 through the reserved connection hole on the base 4, thereby fixing the base 4 in a fixed position in the ocean. By fixing the base 4 with the anchor chain, it can be ensured that the generator 22 and the impeller can safely and effectively complete the power generation work and operate efficiently and safely.

[0045] Example 2:

[0046] This embodiment is an optimization based on the above embodiment 1.

[0047] In order to better drive the impeller curved blade 2, the angle between the impeller flange 3 and the outer surface of the impeller curved blade 2 is an obtuse angle.

[0048] Example 3:

[0049] This embodiment is an optimization based on the above embodiment 1.

[0050] In order to limit the maximum opening angle of the curved blades so that the impeller curved blades 2 can withstand the force of water or wind to the best extent, a limiting component is provided between the cylindrical main shaft 1 and the impeller curved blades 2. The limiting component is used to limit the rotation angle of the impeller curved blades 2.

[0051] like Figure 6 , Figure 7 As shown, specifically, this embodiment provides a specific limiting component, which includes a limiting rod 6 and a limiting part 7. The limiting part 7 is disposed on the upper end face of the cylindrical main shaft 1. The two ends of the limiting rod 6 extending out of the limiting part 7 are respectively connected to the limiting block 8 and the impeller arc blade 2. It should be noted that one end of the limiting rod 6 is fixedly connected to the limiting block 8, which can limit the movement distance of the limiting rod 6 relative to the limiting part 7. When the limiting block 8 is locked by the through hole 7.1 of the limiting part 7, the limiting rod 6 stops moving. At this time, the limiting rod 6 achieves the limiting of the impeller arc blade 2. At this time, the opening angle of the impeller arc blade 2 is limited by the limiting rod 6 to the optimal position of the design value, so that the impeller arc blade 2 can withstand the force of water or wind to the best extent and complete the work. Elastic rubber is provided on the contact surfaces of the limit block 8 and the through hole 7.1 of the limit component 7. The elastic rubber is used to reduce or slow down the impact force when the two come into contact, eliminate noise and extend the service life of the component.

[0052] When wind or water flow increases suddenly, the impeller speed and generator speed increase abruptly, causing unstable power generation, variable speed constant frequency technology is used in existing technologies to achieve stable power output.

[0053] In this embodiment, the limiting component also includes a limiting control structure 5. The limiting control structure 5 and the limiting component 7 are disposed on the upper end face of the cylindrical main shaft 1. The limiting control structure 5 is used to control the technology of stable power output. Specifically, the limiting control structure 5 adopts a car seat belt device, replacing the seat belt in the car seat belt device with a connecting rope 21. All other components are exactly the same as the components in the car seat belt device of the prior art. Specifically, when the wind speed and water flow speed are high, the speed at which the impeller's arc-shaped blades 2 leave the cylindrical main shaft 1 will increase. This causes the connecting rope 21 to pull the rotating shaft in the limit control structure 5 (car seat belt device) to rotate rapidly. The central component generates centrifugal force under the rotation of the rotating shaft, causing the irregular component to extend outward relative to the central component. This allows the teeth of the irregular component to mesh and lock with the outer gear, thereby limiting the rotation of the rotating shaft. The length of the connecting rope 21 is limited, thus limiting the position of the limit lever 6. This locks the angle between the impeller's arc-shaped blades 2 and the cylindrical main shaft 1 within a suitable angle range. The speed and torque of the impeller are controlled simultaneously to ensure the safe operation of the generator 22 and the stable output of electrical energy. It should be noted that the working principle of the limit control structure 5 is based on that of a car seat belt device, except that the seat belt on the car seat belt device is replaced with a connecting rope 21. Its working principle and the winding method of the connecting rope 21 are completely the same as those of the car seat belt device. Therefore, the specific structure and working principle of the limit control structure 5 will not be described in detail here.

[0054] In practical implementation, the size of the limit control structure 5 and the tension of the helical spring within it are determined based on the size of the impeller. The rotational speed of the central component is set with reference to the safe rotational speed of the impeller, the limit parameters that the impeller's curved blades 2 can withstand, and the limit parameters that the generator can withstand. The set parameters must be lower than the limit parameters to ensure safe operation of the equipment. The specifications and material of the connecting rope 21 are preferably nylon or steel wire, matching the size of the impeller. In this embodiment, the parameters of the limit control structure 5 are set with reference to the setting requirements of various parameters of automotive seat belts in the prior art.

[0055] Example 4:

[0056] This embodiment is an optimization based on the above embodiment 1.

[0057] like Figure 5 As shown, the inner end of the impeller arc blade 2 is rotatably connected to the cylindrical main shaft 1 via a hinge 12, which can limit the maximum opening angle of the impeller arc blade.

[0058] Hinges 12 are typically designed with a limited opening angle. When this angle is reached, the structure of hinge 12 prevents further opening to ensure safety and stability. This limiting design prevents damage or accidents caused by excessive opening. Therefore, hinge 12 is preferred as a connecting component to allow the curved blades to open to a limited extent, thus ensuring the normal operation of the impeller. (Hinges 12 are not only used for connecting impeller blades, but also in...) Figure 12 and Figure 10 (Generator in the middle)

[0059] like Figure 16 As shown, an elastic material 12.1, preferably elastic rubber or a spring, can be provided on the hinge 12 to reduce the impact between the two hinge pieces 12 at the limiting point and extend the service life of the hinge 12. The elastic material 12.1 is preferably located near the limiting point of the hinge 12. The elastic rubber or spring can also control the unfolding angle of the curved blades. The metal used to manufacture the hinge 12 is selected from metals with high hardness found in the prior art to ensure the service life of the limiting component in this case and the operational safety of the equipment.

[0060] Example 5:

[0061] This embodiment is an optimization based on the above embodiment 1.

[0062] To better drive the cylindrical spindle 1, the cylindrical spindle 1 is either a hollow cylindrical structure or a solid structure.

[0063] Example 6:

[0064] like Figure 9 As shown, in order to facilitate the fixed installation of the impeller, this utility model also provides an impeller frame structure, which includes an impeller as described in any of the embodiments 1-5, and also includes a central shaft 9 and an impeller frame 10. The cylindrical main shaft 1 is coaxially fixedly connected to the central shaft 9, and the central shaft 9 is rotatably connected to the impeller frame 10.

[0065] The impeller is mounted on the impeller frame 10 and is located inside the impeller frame 10. The two ends of the central shaft 9 are rotatably engaged with the impeller frame 10. Specifically, the impeller frame 10 includes a cubic frame structure and impeller support frames 10.1 set at the upper and lower ends of the cubic frame structure. The two ends of the central shaft 9 are respectively rotatably engaged with the centers of the two impeller support frames 10.1 through bearings 10.2. The impeller frame 10 plays a supporting role for the impeller, as well as a protective role and a role in facilitating transportation. It also facilitates modular assembly with other equipment to provide power to other equipment.

[0066] Preferably, the impeller frame 10 is made of carbon fiber, aluminum alloy, or stainless steel. A tubular material is also preferred, allowing the cable to be installed along the internal space of the tube, thereby protecting the cable from external environmental corrosion and extending its service life.

[0067] Preferably, the impeller and impeller frame 10 can be stacked vertically, with adjacent impeller frames 10 fixedly connected and adjacent central shafts 9 fixedly connected. Preferably, they are fixedly connected by splines. In this case, the impellers in the two impeller frame 10 combined structures in the connected state have synchronous rotation speeds.

[0068] Preferably, positioning points are provided on the upper and lower connecting ends of the central shaft 9. These positioning points are preferably recessed structures and are ideally located on the outer circumferential surfaces of the upper and lower connecting ends of the central shaft 9. Alternatively, the positioning points can be located on the upper and lower splines, with the spline teeth having recessed structures on them. During spline connection, the positioning points on the upper and lower connecting ends of the two central shafts 9 are aligned with each other. The purpose of these positioning points is to ensure that all the curved blades are aligned when multiple impellers are vertically connected. This technology allows all blades to simultaneously receive a large amount of wind and water energy, thereby driving more generators to produce more electricity.

[0069] like Figure 9 As shown, preferably, the lower connecting end of the central shaft 9 does not extend beyond the lower end of the impeller frame 10. When the impeller frame 10 is laid flat on the ground, the lower connecting end is suspended in the air and does not contact the ground, thus preventing damage to the lower connecting end.

[0070] Example 7:

[0071] like Figure 13As shown, this utility model also provides a generator rotating structure, including a generator frame 14, a generator shaft 13, a generator housing 16, and an impeller frame structure as described in Embodiment 6. The two ends of the generator shaft 13 are rotatably connected to the generator frame 14. The generator housing 16 is a cylindrical shell. A plurality of generator arc blades 17 are evenly arranged circumferentially on the cylindrical shell. The inner ends of the generator arc blades 17 are rotatably connected to the cylindrical shell. The rotation axis of the generator arc blades 17 is parallel to the axis of the cylindrical shell. When the generator arc blades 17 are not in operation, they are covered on the cylindrical shell. The outer ends of the generator arc blades 17 are provided with outwardly folded generator flanges 18. The impeller frame 10 is fixedly installed on the generator frame 14. The lower connecting end of the central shaft 9 is fixedly connected to the upper connecting end of the generator shaft 13. The rotation directions of the impeller arc blades 2 and the generator arc blades 17 are opposite. This results in a technical feature that allows the generator housing 16 and the generator shaft 13 to rotate freely relative to each other. When the impeller's central shaft 9 is fixedly installed with the generator main shaft 15, the rotation direction of the impeller's central shaft 9 is opposite to the rotation direction of the generator housing 16, which can double the generator's speed. Specifically, the impeller frame 10 is overlapped and fixed on top of the generator frame 14, and the lower end of the impeller's central shaft 9 is fixedly connected to the upper end of the generator main shaft 15; preferably, the two are connected by a spline.

[0072] After the impeller frame structure and the generator rotating structure are installed vertically, the impeller rotates clockwise, while the generator casing 16 rotates counterclockwise. This technical solution can increase the generator speed and improve power generation when the impeller and generator are driven by the same wind speed or water flow speed. The impeller arc blades 2 are installed clockwise, while the generator arc blades 17 are installed counterclockwise.

[0073] like Figure 15 As shown in the above embodiment, the tubular ribs 14.2 of the generator frame 14 and the impeller frame 10 are hollow structures, allowing the cable 23 to pass through easily. The tubular ribs 14.2 of the generator frame 14 and the impeller frame 10 are fastened together by a clamp structure 25.

[0074] Example 8:

[0075] This embodiment is an optimization based on the above embodiment 7.

[0076] A limiting element is provided between the cylindrical outer casing and the generator's arc-shaped blades 17. This limiting element is used to restrict the rotation angle of the generator's arc-shaped blades. This limiting element is the same as the limiting element for the impeller.

[0077] Example 9:

[0078] This embodiment is an optimization based on the above embodiment 7.

[0079] like Figure 11 As shown, in order to achieve power output, an inner slip ring 19 and an outer slip ring 20 are included. The inner slip ring 19 is installed on the generator main shaft 15 located inside the generator housing 16, and the outer slip ring 20 is installed on the generator main shaft 15 located outside the generator housing 16. A cable 23 is connected between the inner slip ring 19 and the outer slip ring 20.

[0080] The electricity generated by the generator coil is transmitted to the inner slip ring 19 via a cable, and then output from the inner slip ring 19 to the outer slip ring 20 via the cable 23 installed in the through hole of the generator main shaft 15. The outer slip ring 20 then outputs the electricity via a cable installed inside a cable protection tube. Because the generator frame 14 is made of tubular material, the cable inside the protection tube can be extended within the tubular material due to the characteristics of the tubular structure of the generator frame 14, thus protecting the cable and extending its service life.

[0081] Specifically, a cable channel 24 is provided on the generator main shaft 15, which allows for the laying of the cable 23 between the inner slip ring 19 and the outer slip ring 20. The channel 24 forms an elongated groove on the generator main shaft 15, and the groove is symmetrically arranged on both sides of the generator main shaft 15.

[0082] Example 10:

[0083] like Figure 14 As shown, in order to directly apply the impeller of this technical solution to a generator, this utility model also provides a generator frame structure, which includes a generator 22, a generator frame 14, and an impeller frame structure as described in Embodiment 6. The generator 22 includes a generator housing 16 and a generator shaft 13. The generator housing 16 is fixedly connected to the generator frame 14, and the generator shaft 13 is rotatably connected to the generator frame 14. The impeller frame 10 is fixedly installed on the generator frame 14, and the lower connecting end of the central shaft 9 is fixedly connected to the upper connecting end of the generator shaft 13.

[0084] Example 11:

[0085] like Figure 10As shown, in order to improve the existing generator structure, this utility model also provides a turbine generator, which includes a generator frame 14, a generator main shaft 15 and a generator housing 16. The two ends of the generator main shaft 15 are fixedly connected to the generator frame 14. The generator housing 16 is a cylindrical shell (preferably a solid structure). A plurality of generator arc blades 17 are evenly arranged circumferentially on the cylindrical shell. The inner end of the generator arc blade 17 is rotatably connected to the cylindrical shell. The rotation axis of the generator arc blade 17 is parallel to the axis of the cylindrical shell. When the generator arc blade 17 is not working, it covers the cylindrical shell. The outer end of the generator arc blade 17 is provided with an outwardly folded generator flange 18.

[0086] This technical solution operates on the same principle as the impeller. By driving the generator flange 18 with wind or water power, the generator arc-shaped blades 17 are opened, allowing them to withstand further wind or water pressure and begin performing work. This drives the cylindrical outer casing to rotate continuously. Simultaneously, when the generator arc-shaped blades 17 rotate to a non-working position, they can cover and adhere to the cylindrical outer casing. The generator housing 16 exhibits an asymmetrical state during operation, eliminating the resistance from the non-working generator arc-shaped blades 17, improving their efficiency, and reducing the pressure on the generator main shaft 15 from the force driving the arc-shaped blades 17. This reduces the pressure on the generator main shaft 15 bearings, extends their service life, and saves on generator operating costs and maintenance frequency.

[0087] Preferably, the generator frame 14 includes a cubic frame structure and generator support frames 14.1 disposed at the upper and lower ends of the cubic frame structure. The two ends of the generator main shaft 15 are fixedly connected to the center of the two generator support frames 14.1 respectively. The generator frame 14 serves to support the generator, protect it, facilitate transportation, and facilitate modular assembly with other equipment to provide power to other equipment.

[0088] Preferably, the generator support frame 14.1 reinforces the upper and lower parts of the generator frame 14 in a diagonal manner, making the structure of the generator frame 14 more robust and better protecting the generator installed therein. The generator frame 14 is preferably manufactured by welding.

[0089] Preferably, the generator frame 14 is made of carbon fiber, aluminum alloy, or stainless steel. A tubular material is also preferred, allowing the cable to be installed within the tubular space, thereby protecting the cable from external environmental corrosion and extending its service life.

[0090] like Figure 10As shown, the lower connecting end of the generator main shaft 15 does not extend beyond the lower end of the generator frame 14. When the generator frame 14 is laid flat on the ground, the lower connecting end is suspended in the air and does not contact the ground, thus preventing damage to the lower connecting end.

[0091] The generator arc blades 17 mounted on the generator housing 16 function as impellers. Under the action of wind or water power, they can achieve the generator's self-rotation and power generation. The generator no longer needs to be powered by an external independent power conversion device such as an impeller. Its own generator arc blades 17 can achieve the effect of generator self-rotation and self-power generation.

[0092] Under the action of wind or water, the generator arc blades 17 connected to the generator housing 16 can provide rotational power for the generator, thereby generating electrical energy. The electrical energy generated by the generator is transmitted through the inner slip ring 19 installed on it to the outer slip ring 20 outside the generator via a cable. The outer slip ring 20 is then output to the outside via a cable installed in the cable protection pipe.

[0093] In the above embodiments, all manufacturing materials are waterproof, ensuring a completely waterproof manufacturing process. All components related to the power generation unit are waterproofed, including the generator, cables, and external slip ring 20. This prevents water and impurities from entering the generator and disrupting its normal operation, preventing generator leakage or short circuits, and avoiding damage to the power generation unit.

[0094] It should be noted that, Figure 10 The generator and Figure 12 The generators in the two models are identical, but they are connected to the generator frame in different ways. Figure 10 The two ends of the main shaft 15 of the generator column are fixedly connected to the generator frame 14, respectively. Figure 12 Both ends of the generator shaft 13 are rotatably connected to the generator frame 14 via bearings. Specifically, the outer diameter of the generator shaft 13 is fixedly connected to the inner diameter of the bearing, preferably with an interference fit or spline connection. The fixed connection between the outer diameter of the bearing and the generator frame 14 is preferably welded.

[0095] Figure 10 The generators in this system tend to generate electricity independently and do not have the capability to connect multiple generator frames in a fixed, vertically integrated structure to supply power to other equipment. Figure 14 The generator 22 in the example cannot be used alone and needs to be used in conjunction with Example 3 ( Figure 9 Example 6 () is formed by combining an impeller. Figure 14 ).

[0096] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are 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.
