[0003] In the prior art, for example, in the published patent CN202120042015.X, a marine hybrid power generation system is provided. The solution adopts a split-type wing, connecting bracket and protective net to prevent birds and other animals from being caught. The split design is not convenient for assembly, and there are problems with assembly complexity and the stacking of component structures and weights, which affects the rotation efficiency and is not conducive to power generation.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] One of the technical problems that this application aims to solve is that existing vertical axis power generation modules adopt a split fin design, which has a complex structure, large mass, and is not conducive to power generation.

[0006] To address the aforementioned technical problems, in a first aspect, embodiments of this application provide a vertical axis power generation component, mainly comprising a rotating structure, a rotating shaft, and an induction coil. The rotating structure includes a fan blade and a cover. Multiple air guide grooves are uniformly machined around the fan blade. The cover is fixedly connected to a first port of the fan blade. The rotating shaft is detachably connected to the side of the cover facing the fan blade and is coaxial with the cover. A first magnetic element is provided at the end of the rotating shaft away from the cover. The induction coil is arranged around the first magnetic element.

[0007] In some embodiments, the width of the air guide groove first increases and then decreases along the axial direction of the rotation shaft.

[0008] In some embodiments, fan blades are formed between adjacent air guide slots, and the two sidewalls of the fan blades forming the air guide slots are both arc-shaped surfaces, with the center of the arc-shaped surfaces located on the same side of the fan blades.

[0009] In some embodiments, the two sidewalls of the fan blade are angled together.

[0010] In some embodiments, the fan blade is provided with a first connecting bracket, which is connected to the rotating shaft.

[0011] In some embodiments, the vertical axis power generation assembly further includes a support housing, which is disposed opposite to the second port of the wind turbine blade. A suspension structure is disposed between the support housing and the rotating structure, and the suspension structure pushes against the rotating structure so that the rotating structure forms a floating gap with the support housing in the axial direction of the rotating shaft.

[0012] In some embodiments, the suspension structure includes a second magnetic element and a third magnetic element arranged opposite to each other. The second magnetic element is fixedly connected to a rotating shaft, and the third magnetic element is fixedly connected to a support housing. The magnetic poles of the second magnetic element and the third magnetic element are arranged in opposite directions.

[0013] In some embodiments, the second magnetic element is a magnetic ring with its inner ring coaxial with the rotation shaft, the support housing includes a second connecting bracket, and the third magnetic element is a magnetic ring fixedly connected to the second connecting bracket, with its inner ring coaxial with the rotation shaft and in clearance fit.

[0014] In some embodiments, the support housing includes a third connecting bracket, and a first bearing is disposed between the third connecting bracket and the rotating shaft.

[0015] Secondly, embodiments of this application provide a power generation device, including an energy storage circuit and a vertical axis power generation component as described above, wherein the induction coil of the vertical axis power generation component is electrically connected to the energy storage circuit.

[0016] Through the above technical solution, the vertical axis power generation component and power generation equipment provided in this application, wherein the vertical axis power generation component mainly includes a rotating structure, a rotating shaft, and an induction coil. The rotating structure includes a fan blade and a cover. Multiple air guide grooves are uniformly machined around the periphery of the fan blade. The cover is fixedly connected to the first port of the fan blade. The rotating shaft is detachably connected to the side of the cover facing the fan blade and is coaxial with the cover. A first magnetic element is provided at the end of the rotating shaft away from the cover. The induction coil is arranged around the first magnetic element. The multiple air guide grooves on the fan blade achieve an integrated design, forming a rotating body that can rotate with the wind power, thereby driving the rotating shaft to rotate. The rotating shaft then transmits power to the first magnetic element, which cooperates with the induction coil to convert wind energy into electrical energy. The air guide grooves realize the utilization of wind power. They are formed by processing rather than assembly, making the fan blade a whole structure. On the one hand, this avoids the increase in parts and assembly difficulties caused by assembly. On the other hand, the overall structure is compact and relatively lightweight, which is more conducive to the collection and transmission of wind power. This application effectively solves the problem that the existing vertical axis power generation components adopt a split fin design, which has a complex structure, large mass, and is not conducive to power generation.

[0034] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0035] like Figures 1 to 4 As shown, in a first aspect, some embodiments of this application provide a vertical axis power generation assembly, mainly including a rotating structure 10, a rotating shaft 20, and an induction coil 30. The rotating structure 10 includes a fan blade 11 and a cover 12. The fan blade 11 has a plurality of air guide grooves 111 uniformly processed around its periphery. The cover 12 is fixedly connected to the first port 112 of the fan blade 11. The rotating shaft 20 is detachably connected to the side of the cover 12 facing the fan blade 11 and is coaxial with the cover 12. A first magnetic element 21 is provided at the end of the rotating shaft 20 away from the cover 12. The induction coil 30 is arranged around the first magnetic element 21.

[0036] The power generation principle of the above-mentioned vertical axis power generation component is as follows: the multiple air guide slots 111 set on the fan blade 11 realize the integrated design, forming a rotating body that can be rotated by wind power, thereby driving the rotating shaft 20 to rotate. The rotating shaft 20 then transmits the power to the first magnetic component 21. The first magnetic component 21 cooperates with the induction coil 30 to convert kinetic energy into electrical energy.

[0037] The wind guide duct 111 utilizes wind power through machining, not assembly, making the wind turbine 11 a single, integrated structure. This avoids the increased number of parts and assembly difficulties associated with assembly, resulting in a more compact structure and reduced overall weight. Furthermore, the machining error is significantly smaller than the assembly error of multiple components, leading to better rotational balance of the wind turbine 11. The reduced weight also significantly increases rotational speed under wind pressure, thus better converting wind energy into electrical energy. This application effectively solves the problem of existing vertical axis power generation components using a split-blade design, which is complex, heavy, and detrimental to power generation.

[0038] It is understood that the vertical axis power generation component in this embodiment can be applied in energy-saving factories. It can be installed on the top of the factory area or in the ventilation duct. It generates electricity by utilizing external wind or air convection caused by the temperature difference between the indoor and outdoor areas of the factory. The generated electricity can be collected and used in the factory area or fed into the national grid and transmitted to the outside, thus achieving the effect of effectively utilizing wind energy.

[0039] It should be noted that the vertical axis power generation components put into operation in the factory area, especially the vertical axis power generation components located in the ventilation duct, can also be used in reverse by powering on. That is, through the conversion of electrical energy, the induction coil is energized to drive the first magnetic component 21 to rotate, thereby driving the fan blade 11 to rotate and achieve the function of guiding airflow.

[0040] like Figure 2 and Figure 3 As shown, in some embodiments of this application, multiple first magnetic elements 21 of equal size are arranged around the rotation shaft 20. This increases the amount of magnetic field lines, thereby increasing power generation, and also effectively balances the rotation shaft 20, resulting in better balance during rotation.

[0041] In some alternative embodiments, the induction coil 30 and the first magnetic element 21 can be arranged in multiple groups, with the multiple groups of induction coil 30 and first magnetic element 21 distributed sequentially along the axial direction of the rotation shaft 20, and the induction coil 30 and first magnetic element 21 positioned away from the cover 12 on the rotation shaft 20. This arrangement is used to increase power generation, fully convert wind energy into electrical energy, and at the same time lower the center of gravity of the entire rotation shaft 20, which is beneficial to the stable operation of the entire vertical axis power generation assembly.

[0042] like Figures 1 to 4 As shown, in some embodiments of this application, the width of the air guide groove 111 first increases and then decreases along the axial direction of the rotation shaft 20. This arrangement causes the amount of gas flowing into the middle of the air guide groove 111 to be greater than that at both ends, which generates a velocity difference, i.e., the gas velocity in the middle of the air guide groove 111 is less than that at both ends, thereby causing the airflow to flow from the high-pressure side to the low-pressure side, thus driving the entire fan blade 11 to rotate.

[0043] It is understandable that the width of the air guide slot 111 varies along the same direction, that is, the driving force generated is along the tangent direction of the arc of the entire cross-section of the fan blade 11. The driving force generated by the air guide slots 111 at multiple positions, in conjunction with the constraint of the rotating shaft 20, causes the fan blade 11 to rotate around its axis.

[0044] In some embodiments of this application, along the axial direction of the rotation shaft 20, the width of the air guide groove 111 changes from large to small and then from small to large. That is, the width of the groove changes more gradually in the area near the middle of the air guide groove 111, while the width changes more significantly in the area far from the middle of the air guide groove 111. This arrangement can generate a relatively larger driving force near the middle of the air guide groove 111, resulting in a better driving effect. The positions of the first port 112 and the second port 113 are connection points, which need to maintain the stability of the structure. Therefore, the direct driving force generated is relatively small, which is also conducive to the balance of rotation.

[0045] like Figures 1 to 4 As shown, in some embodiments of this application, a fan blade 114 is formed between adjacent air guide slots 111. The two sidewalls of the fan blade 114 forming the air guide slot 111 are both arc-shaped surfaces, and the center of the arc-shaped surface is located on the same side of the fan blade 114. The above arrangement makes the direction of the air guide slot 111 fixed, and can form two arc-shaped surfaces with different arc lengths, thereby generating driving force. This driving effect is good, and the direction can be kept consistent, so as to drive the fan blade cylinder 11 to rotate.

[0046] In some embodiments of this application, the two sidewalls of the fan blade 114 are arranged at an angle. The angled arrangement means that the space formed between the two sidewalls varies along the direction from the outer wall to the inner wall of the fan blade cylinder 11, thus changing the airflow and generating greater driving force, thereby increasing the conversion of wind energy.

[0047] In some alternative embodiments, with a cross section perpendicular to the axis of the fan blade 11, the width of the air guide 111 gradually decreases along the direction from the outer wall to the inner wall of the fan blade 11. That is, within the same plane, the airflow will accelerate after entering the air guide 111, thereby increasing the pressure on the side wall and generating driving force.

[0048] Furthermore, in a cross-section perpendicular to the axis of the wind turbine 11, the offset angle of the longer side of the wind guide 111 along the axis close to the wind turbine 11 is greater than the offset angle of the shorter side of the wind guide 111 along the axis close to the wind turbine 11. This results in a larger airflow impact angle on the longer side of the wind guide 111, and the shorter side of the wind guide 111 has the function of guiding the airflow to the longer side of the wind guide 111, thereby increasing the driving effect at this position, resulting in greater driving force and a greater amount of wind energy converted into electrical energy.

[0049] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the fan blade cassette 11 is provided with a first connecting bracket 115, which is connected to the rotating shaft 20. The first connecting bracket 115 is provided to connect with the rotating shaft 20, and the relatively low position enables the transmission of the rotating shaft 20, that is, to apply driving force to the rotating shaft 20. This structure is simple, directly connected, and also serves to support the fan blade cassette 11, preventing the fan blade 114 from deforming towards the fan blade cassette 11 due to wind force.

[0050] Understandably, the first connecting bracket 115 is positioned on the side near the second port 113 and opposite to the cover 12, forming a support for both ends of the fan blade 11 and playing a role in stabilizing the structure.

[0051] In some alternative embodiments, a speed regulator and a rotating bearing are provided between the first connecting bracket 115 and the rotating shaft 20, thus forming a rotating connection between the first connecting bracket 115 and the rotating shaft 20. When the wind force is strong, in order to prevent the high-speed rotating fan blade 11 from generating too fast a rotation speed, which could damage other internal components, the speed regulator can limit the maximum speed transmitted from the first connecting bracket 115 to the rotating shaft 20, so as to protect the rotating shaft 20 from being directly damaged.

[0052] In some alternative embodiments, such as Figure 6 and Figure 7 As shown, a connecting clip 121 is provided at the central axis position of the cover 12, and a snap-fit ​​end 23 is provided at the end of the rotating shaft 20 away from the first magnetic component 21. The connecting clip 121 and the snap-fit ​​end 23 are snapped together to fix the cover 12 relative to the rotating shaft 20. This arrangement structure is more compact, that is, the cover 12, the rotating shaft 20 and the fan blade 11 are fixed to each other, so that the rotation of the rotating shaft 20 is more precise and controllable, and more electrical energy can be converted outward.

[0053] like Figures 1 to 3 as well as Figure 5 As shown, in some embodiments of this application, the vertical axis power generation assembly further includes a support housing 40, which is positioned opposite the second port 113 of the wind turbine cascade 11. A suspension structure 50 is provided between the support housing 40 and the rotating structure 10, and the suspension structure 50 pushes against the rotating structure 10 to create a floating gap between the rotating structure 10 and the support housing 40 along the axial direction of the rotation shaft 20. The support housing 40 and the suspension structure 50 are used for fixed installation and the installation of the independent wind turbine cascade 11, providing a better rotational connection. The floating gap allows the rotating structure 10 to suspend, eliminating interference between it and the support housing 40, reducing relative friction during rotation, and enabling better wind power conversion.

[0054] like Figure 2 , Figure 3 as well as Figure 5 As shown, in some embodiments of this application, the levitation structure 50 includes a second magnetic element 51 and a third magnetic element 52 arranged opposite each other. The second magnetic element 51 is fixedly connected to the rotation shaft 20, and the third magnetic element 52 is fixedly connected to the support housing 40. The magnetic poles of the second magnetic element 51 and the third magnetic element 52 are arranged in opposite directions. The arrangement of the second magnetic element 51 and the third magnetic element 52, with opposite magnetic poles, enables the rotation shaft 20 to float, thereby driving the rotating structure 10 fixed to it to float. The arrangement of the second magnetic element 51 and the third magnetic element 52 is simple and easy to assemble, while the magnetic elements can maintain the stability of the assembly and provide a good foundation for rotation.

[0055] In some alternative embodiments, the suspension structure 50 can also be a gas suspension structure, for example, a gas baffle is provided on the rotating shaft 20 and a gas outlet is provided on the supporting housing 40, so that an airflow is generated to blow the gas baffle, thereby driving the rotating shaft 20 to suspend.

[0056] It is understandable that when gas is suspended, the electrical energy generated by the vertical axis power generation component can be used to generate airflow, thereby achieving an internal circulation setting of the current. The electrical energy required to generate the levitation is much less than the actual electrical energy converted by the vertical axis power generation component.

[0057] like Figure 2 , Figure 3 as well as Figure 5 As shown, in some embodiments of this application, the second magnetic element 51 is a magnetic ring, with its inner ring coaxial with the rotation shaft 20. The support housing 40 includes a second connecting bracket 41, and the third magnetic element 52 is a magnetic ring fixedly connected to the second connecting bracket 41. Its inner ring is coaxial with the rotation shaft 20 and has a clearance fit. This arrangement ensures that the repulsive force between the second magnetic element 51 and the third magnetic element 52 is parallel to the axial direction of the rotation shaft 20, resulting in better compatibility and not affecting its rotation. Simultaneously, the levitation effect provides circumferential restraint, preventing large radial offsets. Even if an offset occurs, it can be reversed, maintaining a stable rotation center. The deviation between the rotation center and the axis of the rotation shaft 20 is within a controllable range.

[0058] like Figure 2 , Figure 3 as well as Figure 5 As shown, in some embodiments of this application, the support housing 40 includes a third connecting bracket 42, and a first bearing 22 is disposed between the third connecting bracket 42 and the rotating shaft 20. The third connecting bracket 42 and the first bearing 22 are provided to support the rotating shaft 20 and adapt to the rotation of the rotating shaft 20. The first bearing 22 may be a thrust roller bearing, which can withstand axial loads and radial combined loads. Thrust roller bearings have a low coefficient of friction and a high rotational speed, and have a self-aligning function, making them more suitable for the rotational requirements of vertical power generation components.

[0059] In some alternative embodiments, the support housing 40 includes an annular shell 43, the size of which is adapted to the fan blade 11, and can be used to support the fan blade 11 in the absence of wind.

[0060] The first connecting bracket 115, the second connecting bracket 41, and the third connecting bracket 42 all have multiple connecting rods. The orientation of the connecting rods is perpendicular to the axis of the rotating shaft 20. Furthermore, adjacent connecting rods on the second connecting bracket 41 and the third connecting bracket 42 are arranged parallel to each other, which provides better structural support and makes them less prone to damage.

[0061] Secondly, in some embodiments of this application, a power generation device is provided, which mainly includes an energy storage circuit and a vertical axis power generation component as described in any of the above embodiments. The induction coil 30 of the vertical axis power generation component is electrically connected to the energy storage circuit. The beneficial effects of the vertical axis power generation component are described in the above embodiments and will not be repeated here. This integrates power generation and energy storage, making it usable as an energy source for the plant area.

[0062] Understandably, the main working principle of power generation equipment is as follows:

[0063] When the vertical axis power generation unit installed on the roof is subjected to natural wind or air convection caused by the temperature difference between the inside and outside of the plant, the fan blade 114 will rotate. Please refer to [link / reference needed]. Figures 1 to 4 When the fan blade 114 rotates, that is, when the fan tube 11 rotates, it drives the rotating shaft 20 to rotate together. Due to the repulsive force between the second magnetic component 51 and the third magnetic component 52 of the suspension structure 50, the rotating shaft 20 is suspended in the air. The rotating shaft 20 has almost no rotational friction, so it can rotate easily and continuously, thereby driving the first magnetic component 21 at the bottom to rotate. The first magnetic component 21 includes an N-pole magnet and an S-pole magnet. During the rotation of the first magnetic component 21, a changing magnetic field is generated. The induction coil 30 in the magnetic field generates current according to the battery law, completing the power generation process. The generated electricity is processed by filtering, voltage stabilization and other technologies and then enters the energy storage circuit for storage. It is then supplied to the factory through the inverter.

[0064] High-density batteries can be installed in the energy storage circuit to store electrical energy for later use. It also facilitates reversing the energy storage circuit to enable the active rotation of the vertical axis power generation components, thereby assisting in the exchange of airflow inside and outside the plant.

[0065] The embodiments of this application have now been described in detail. To avoid obscuring the concept of this application, some details known in the art have not been described.
