Description

Technical Field

[0001] This utility model relates to the technical field of wind power generation, and more particularly to a suspended high-speed multi-layer power generation device. Background Technology

[0002] With the increasing global emphasis on green energy, wind power has become an important technology in the renewable energy field. However, in most traditional wind power generation devices, the weight of the drive shaft and blades relies entirely on the support frame and bearings. Although this structure is simple, it presents technical problems in actual operation.

[0003] First, when the drive shaft and blades act directly on the bearing, the resulting frictional resistance not only increases the initial wind force required to start the device, but also reduces energy efficiency during continuous operation, resulting in energy loss. For small or low-wind-speed power generation equipment, this friction and resistance become a serious limitation, affecting the start-up sensitivity and total output power.

[0004] Secondly, traditional bearings bear long-term weight and dynamic loads, which can easily lead to wear, heat generation and structural fatigue, thereby shortening equipment life, increasing maintenance frequency and costs. This is an issue that needs to be addressed in scenarios that require long-term operation and are difficult to maintain frequently (such as remote areas or offshore wind farms).

[0005] Furthermore, the current structures of small or medium-sized wind turbines often lack "weight reduction design" for the load on the drive shaft and blades, which requires additional reinforcement of the structural strength and material selection of the device, further increasing manufacturing costs and installation burden.

[0006] In view of this, in order to solve the above problems, this utility model proposes a suspended high-speed multilayer power generation device that can effectively reduce axial frictional resistance, improve operating efficiency and accelerate power output. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a suspended high-speed multilayer power generation device that can effectively reduce axial frictional resistance, improve operating efficiency and accelerate power output.

[0008] To solve the above problems and achieve the purpose of this utility model, the technical means of this utility model is as follows: a suspended high-speed multi-layer power generation device, comprising: a fixed frame assembly, including a first frame, a second frame, and multiple fixed columns connecting the first frame and the second frame, wherein a through hole is provided in the center of the first frame; a drive unit, which is disposed between the first frame and the second frame, and the drive unit includes: a shaft that vertically penetrates the first frame and the second frame, and at least one box-shaped blade is provided on its outer edge, wherein the top end of the shaft passes through the through hole and is provided with a thread and a first nut, which is screwed onto the thread and abuts against the top of the first frame for positioning and fixing the shaft and a second nut, which is screwed onto the thread, located above the first nut and rotatable for adjustment, and pushes against the first nut by tightening, thereby pulling up the lower end of the shaft, so that the drive unit and the connected box-shaped blade are in a suspended state, thereby reducing axial load, reducing rotational resistance and improving operating efficiency;

[0009] At least one bearing is disposed at the position where the shaft extends out of the first frame to assist the rotation of the shaft;

[0010] At least one speed-increasing device is disposed within the fixed frame assembly and coaxially connected to the shaft to increase the output speed of the shaft;

[0011] At least one power generation device is located at the corner of the second frame and connected to the speed multiplier device to receive power output and generate electrical energy;

[0012] A green energy storage device is installed at one end of the drive unit and stores electrical energy inside to provide initial power to start the operation of the suspended high-speed multi-layer power generation device.

[0013] Furthermore, in the above technical solution, the bearing is a ball bearing or a roller bearing.

[0014] Furthermore, in the above technical solution, the fixed frame set also includes at least one third frame, which is disposed between the first frame and the second frame, serving as a support and guide structure for the drive unit.

[0015] Furthermore, in the above technical solution, the speed multiplier device further includes: a drive wheel coaxially arranged with the shaft, and a driven wheel correspondingly arranged at one end of the power generation device and connected to the drive wheel. The drive wheel is driven to rotate synchronously by the rotation of the shaft, thereby driving the driven wheel to rotate, so as to increase the output speed of the drive unit and further drive the power generation device to operate and generate electricity.

[0016] Furthermore, in the above technical solution, the driving wheel and the driven wheel are rotating components. The driving wheel consists of a first plate and a second plate spaced apart, and multiple first arms connected between the first plate and the second plate and spaced apart from each other. The driven wheel consists of a rotating shaft located at one end of the power generation device and connected to the power generation device, and a second arm extending outward from the periphery of the rotating shaft and capable of being turned by the first arms to drive the rotating shaft to rotate.

[0017] Furthermore, in the above technical solution, the first frame is composed of a first frame body disposed at the top of the shaft, a first longitudinal rod disposed inside the first frame body, and a first transverse rod disposed intersecting with the first longitudinal rod body, while the second frame is composed of a second frame body disposed at the bottom of the shaft body, a second longitudinal rod disposed inside the second frame body, and a second transverse rod disposed intersecting with the second longitudinal rod body.

[0018] Furthermore, in the above technical solution, the power generation device is also electrically connected to a power storage device for storing the electrical energy generated by the power generation device. The power storage device includes a power output port for outputting the stored electrical energy to an external power supply device or mains power.

[0019] Furthermore, in the above technical solution, the first nut also has a screw hole, and a locking screw is provided at the screw hole. The screw hole passes through the first nut and can be screwed in to contact the shaft. By tightening the locking screw, an additional fixing force is provided to prevent the first nut from loosening during operation.

[0020] Furthermore, in the above technical solution, the suspended high-speed multi-layer power generation device also includes an auxiliary power generation device. The auxiliary power generation device includes: an AC-DC converter electrically connected to the suspended high-speed multi-layer power generation device to convert the output AC power into DC power; a first charge-discharge controller electrically connected to the AC-DC converter to control the storage and release of energy; a first motor energy storage device electrically connected to the first charge-discharge controller to store the converted electrical energy; and a motor disposed at one end of the suspended high-speed multi-layer power generation device and electrically connected to the first motor energy storage device. The motor drives the shaft of the suspended high-speed multi-layer power generation device to rotate, thereby reducing the rotational torque required when the suspended high-speed multi-layer power generation device starts and improving starting stability and efficiency.

[0021] After adopting the above technical solution, this utility model has the following effects and functions compared with the prior art:

[0022] This invention, through the setting of threads, a first nut, and a second nut, can lift and suspend the shaft, effectively distributing the vertical load applied to the bearing by the drive unit and the fan blade assembly. By transferring the weight upward to the fixed point above the frame, the overall structure's load-bearing capacity and durability are significantly improved, while reducing pressure on the bearing, lowering friction loss and starting resistance, and enabling the entire device to start and operate stably more easily in low wind speed environments.

[0023] By using bearings, it is possible to ensure low friction and high stability when the shaft rotates in a suspended state, which helps to extend the service life and overall operating efficiency of the suspended high-speed multi-layer power generation device.

[0024] Through the rotational transmission structure of the driving wheel and the driven wheel, the low-speed input power of the drive unit can be effectively transmitted at a higher speed, thereby increasing the output speed of the power generation device and greatly improving the operating efficiency and power generation efficiency of the power generation device.

[0025] By combining box-shaped blades with a suspended design, the wind-driven start-up threshold can be significantly reduced and the torque conversion capability can be improved, enabling the suspended high-speed multi-layer power generation device to start generating electricity quickly even in low wind speed environments, thus enhancing the practicality and reliability of the application.

[0026] Because this utility model adopts a suspended design, it can effectively bear a larger vertical load on the shaft, and thus can be equipped with more speed multipliers. This not only improves the structural expandability, but also increases the overall speed multiplier, further enhancing the power output and power generation efficiency of the power generation device.

[0027] By using an auxiliary power generation device, the rotational torque required for the start-up of the suspended multi-layer power generation device can be reduced, thereby improving start-up stability and efficiency. Attached Figure Description

[0074] 100-fold levitation multi-layer power generation device Detailed Implementation

[0075] To provide a more concrete understanding of the aforementioned purposes, effects, and features of this work, the following description is provided with reference to the accompanying drawings:

[0076] like Figures 1 to 3 As shown in the figure, a suspended high-speed multi-layer power generation device is disclosed, comprising: a fixed frame assembly 1, which includes a first frame 11, a second frame 12, and a plurality of fixed columns 13 connecting the first frame 11 and the second frame 12, wherein a through hole 14 is provided in the center of the first frame 11; and a drive unit 2, which is disposed between the first frame 11 and the second frame 12, and the drive unit 2 includes: a shaft 21 that perpendicularly penetrates the first frame 11 and the second frame 12, and at least one box-shaped blade 22 is provided on its outer edge. The top end of the shaft 21 passes through the through hole 14 and is provided with a thread 23 and a first nut 24. The nut 24 is screwed onto the thread 23 and abuts against the top of the first frame 11 for positioning and fixing the shaft 21 and a second nut 25, which is screwed onto the thread 23, located above the first nut 24 and can be rotated and adjusted. By tightening the nut 24, the shaft 21 is pushed against the first nut 24, thereby pulling up the lower end of the shaft 21, so that the drive unit 2 and the connected box blade 22 are in a suspended state, thereby reducing axial load, reducing rotational resistance and improving operating efficiency.

[0077] At least one bearing 3 is disposed at the position where the shaft 21 extends out of the first frame 11 to assist the shaft 21 in rotating; at least one speed multiplier 4 is disposed within the fixed frame assembly 1 and coaxially connected to the shaft 21 to increase the output speed of the shaft 21; at least one power generation device 5 is disposed at the corner position of the second frame 12 and connected to the speed multiplier 4 to receive power output and generate electrical energy; a green energy storage device 6 is disposed at one end of the drive unit 2 and stores electrical energy inside to provide initial power supply to start the operation of the suspended speed multiplier multilayer power generation device 100.

[0078] The screw thread 23, the first nut 24 and the second nut 25 can be used to suspend the shaft 21, effectively sharing the vertical load applied to the shaft 21 by the drive unit 2 and the box blade 22. By transferring the weight upward to the fixed point above the fixed frame assembly 1, the pressure on the bearing 3 is reduced, friction loss and starting resistance are reduced, and the whole device can be started and operated more easily and stably in low wind speed environments.

[0079] As described above, the fixed frame set 1 further includes at least one third frame 15, which is disposed between the first frame 11 and the second frame 12, serving as a support and guide structure for the drive unit 2.

[0080] The third frame 15 serves as an intermediate guide and reinforcement structure, which helps improve the stability and structural rigidity of the drive unit 2 during vertical operation and reduces structural fatigue and energy loss caused by vibration or sway.

[0081] like Figure 1 As shown, the power generation device 5 is also electrically connected to a power storage device 7 for storing the electrical energy generated by the power generation device 5. The power storage device 7 includes a power output port 71 for outputting the stored electrical energy to an external power supply device or mains power.

[0082] The energy storage device 7 can store the electrical energy generated by the power generation device 5 and output it flexibly through the power output port 71. This allows the energy to be used by external electrical equipment or connected to the mains power network, enabling diverse power applications and improving energy efficiency.

[0083] like Figure 2 As shown, the first frame 11 is composed of a first frame 111 disposed at the top end 211 of the shaft 21, a first longitudinal rod 112 disposed inside the first frame 111, and a first transverse rod 113 intersecting with the first longitudinal rod 112. The second frame 12 is composed of a second frame 121 disposed at the bottom end 212 of the shaft 21, a second longitudinal rod 122 disposed inside the second frame 121, and a second transverse rod 123 intersecting with the second longitudinal rod 122.

[0084] The combination and fixation of the first frame 11 and the second frame 12 with the fixed column 13 can evenly distribute the axial and radial forces of the shaft 21 during operation to the fixed column 13, effectively reducing stress concentration and improving the torsional resistance, seismic resistance and load-bearing capacity of the fixed frame assembly 1, thus ensuring the stability of the suspended multi-layer power generation device 100 during operation.

[0085] like Figure 2 and Figure 3 As shown, the speed multiplier device 4 further includes: a drive wheel 41 coaxially arranged with the shaft 21, and a passive wheel 42 correspondingly arranged at one end of the power generation device 5 and connected to the drive wheel 41. The drive wheel 41 is driven to rotate synchronously by the rotation of the shaft 21, thereby driving the passive wheel 42 to rotate, so as to increase the output speed of the drive unit 2 and further drive the power generation device 5 to operate and generate electricity.

[0086] The rotational transmission structure of the drive wheel 41 and the driven wheel 42 can effectively transmit the low-speed input power of the drive unit 2 at a higher speed, thereby further improving the operating efficiency and power generation efficiency of the power generation device 5.

[0087] like Figure 3 As shown, the bearing 3 is a ball bearing or a roller bearing.

[0088] The bearing 3 ensures that the shaft 21 maintains low friction and high stability when rotating in a suspended state, which helps to extend the service life and overall operating efficiency of the suspended high-speed multi-layer power generation device 100.

[0089] like Figure 3 As shown, the driving wheel 41 and the driven wheel 42 are rotating components. The driving wheel 41 is composed of a first plate 411 and a second plate 412 spaced apart, and multiple first arms 413 connected between the first plate 411 and the second plate 412 and spaced apart from each other. The driven wheel 42 is composed of a rotating shaft 421 disposed at one end of the power generation device 5 and connected to the power generation device 5, and a second arm 422 extending outward from the periphery of the rotating shaft 421 and capable of being turned by the first arms 413 to drive the rotating shaft 421 to rotate.

[0090] The actuation design between the first arm 413 and the second arm 422 ensures smooth contact during power transmission, achieves efficient mechanical power transmission, reduces friction and wear during operation, minimizes energy loss, and achieves high power transmission efficiency.

[0091] like Figure 3 As shown, the first nut 24 also has a screw hole 241, and a locking screw 26 is provided at the screw hole 241. The screw 26 passes through the first nut 24 and can be screwed into contact with the shaft 21. By tightening the locking screw 26, additional fixing force is provided to prevent the first nut 24 from loosening during operation.

[0092] like Figure 4 and Figure 5 As shown, the suspended multi-level power generation device 100 further includes an auxiliary power generation device 8. The auxiliary power generation device 8 includes: an AC-DC converter 81 electrically connected to the suspended multi-level power generation device 100 to convert the output AC power into DC power; a first charge-discharge controller 82 electrically connected to the AC-DC converter 81 to control the storage and release of energy; a first motor energy storage device 83 electrically connected to the first charge-discharge controller 82 to store the converted electrical energy; and a motor 84 disposed at one end of the suspended multi-level power generation device 100 and electrically connected to the first motor energy storage device 83. The motor 84 drives the shaft 21 of the suspended multi-level power generation device 100 to rotate, thereby reducing the rotational torque required for the suspended multi-level power generation device 100 to start, thus improving starting stability and efficiency.

[0093] The structure, features, and effects of this utility model have been described in detail above with reference to the embodiments shown in the accompanying drawings. The above are only preferred embodiments of this utility model and are not intended to limit the scope of implementation. Therefore, any modifications that are consistent with the intent of this utility model should fall within the scope of this utility model patent as long as they have equivalent effects.
