The support body 1 is disposed vertically with respect to the ground, the fan assembly 2 is rotatably mounted on the support body 1 along the circumferential direction of the axis of the support body 1, and at least two sets of the fan assembly 2 are disposed at intervals in the axial direction of the support body 1.

[0035] In the power generating device according to this embodiment, the support body 1 is disposed vertically to the ground, and the fan assembly 2 is rotatably attached to the support body 1 along the circumferential direction of the axis of the support body 1, so that when the wind blows, the fan assembly 2 can rotate in the circumferential direction of the axis of the support body 1, and at least two sets of fan assemblies 2 are disposed at intervals in the axial direction of the support body 1, so that the contact area with the wind can be increased, which can capture wind energy more effectively and increase the total amount of wind energy that can be converted per unit time, and further contribute to improving the utilization rate of wind energy resources. Furthermore, the provision of at least two sets of fan assemblies 2 can improve the structural stability of the entire power generating device and reduce vibration and resonance caused by the action of wind force, thereby extending the service life of the equipment.

[0036] As shown in Figures 1 to 4, a linear chute 101 extending in the axial direction of the support body 1 is formed in the side wall of the support body 1, and the fan assembly 2 includes a first sleeve 21. The first sleeve 21 is fitted onto the outside of the support body 1, and an annular chute structure 22 is formed in the inner wall of the first sleeve 21. The power generating apparatus further includes a first drive assembly 3, which includes a first drive member 31, a slider structure 32, and a limit structure 33. The fixed end of the first drive member 31 is attached to the support body 1, and the drive end of the first drive member 31 extends into the inside of the support body 1. The slider structure 32 is located inside the support body 1, and the slider structure 32 is operably connected to the drive end of the first drive member 31. Under the action of the first drive member 31, the slider structure 32 moves along the axial direction of the support body 1. One end of the limit structure 33 is attached to the slider structure 32, and the other end of the limit structure 33 extends along the radial direction of the support body 1, and extends through the linear chute 101 to the inside of the annular chute structure 22. The other end of the limit structure 33 slides within the annular chute structure 22 as a sliding end.

[0037] Under the action of the first driving member 31, the slider structure 32 moves inside the support body 1 along the axial direction of the support body 1, thereby driving the first sleeve 21 of the fan assembly 2 to move in the axial direction of the support body 1, thereby adjusting the spacing between two adjacent fan assemblies 2.

[0038] In the power generating device according to this embodiment, in the first driving assembly 3, the limit structure 33 extends outside the support body 1 inside the support body 1 and into the annular chute structure 22 of the first sleeve 21, so that the first sleeve 21 can rotate along the circumferential direction of the axis of the support body 1, and further facilitates the rotation of the fan 24. In addition, the slider structure 32 is easily moved along the axial direction of the support body 1 in the support body 1 by being driven by the first driving member 31, so that the interval between the two adjacent sets of two fan assemblies 2 can be accurately adjusted, and the position can be adjusted according to the wind conditions and power generation needs, thereby reducing the interference caused by the air flow, and improving the flexibility and efficiency of wind energy conversion.

[0039] In this embodiment, the fan assembly 2 further includes a fixed rod 23 and a fan 24, the fixed rod 23 is located outside the first sleeve 21, one end along its axis is fixed to the outer wall of the first sleeve 21, and the other end along its axis extends radially away from the support body 1, and at this time, the fan 24 is attached to the other end along the axis of the fixed rod 23.

[0040] Furthermore, the number of fans 24 in each fan assembly 2 is not particularly limited and may be one, two or more.

[0041] Preferably, when the number of fans 24 is at least two, the at least two fans 24 are arranged at equal intervals in the circumferential direction of the axis of the support body 1 .

[0042] In this embodiment, one of the fans 24 extends in the axial direction of the support body, and when the fan 24 is long, one fan 24 corresponds to two or more fixed rods 23 spaced apart in order to improve the reliability of the connection between the fan 24 and the first sleeve 21.

[0043] Furthermore, in order to further improve the reliability of the connection between the fan 24 and the first sleeve 21, a diagonal brace is additionally provided between the support body 1 and the fan 24.

[0044] Similarly, in this embodiment, the number of fan assemblies 2 is not particularly limited, and may be two or more.

[0045] In one embodiment, when two sets of fan assemblies 2 are provided, a set of first drive assemblies 3 is provided correspondingly, in which case the first drive assembly 3 is operatively connected to one of the two sets of fan assemblies 2.

[0046] Of course, in other preferred embodiments, when two or more sets of fan assemblies 2 are provided, for example, in the case of N sets (N is a positive integer greater than 2), the number of first drive assemblies 3 is (N-1), where the (N-1) sets of first drive assemblies 3 are all mounted on the support body 1, and each stud 34, each guide post 35, each slider structure 32, and each limit structure 33 are mounted away from other members, thereby avoiding interference when moving and affecting the necessary adjustment of the position of the fan assembly 2.

[0047] As shown in Figures 1, 3 and 4, the first drive assembly 3 further includes a stud 34 and a guide post 35, the stud 34 is rotatably mounted inside the support body 1 and is operably connected to the drive end of the first drive member 31, the guide post 35 is fixedly mounted inside the converter and has an axis parallel to the axis of the stud 34, and the slider structure 32 is provided with a screw hole and a through hole, the screw hole is screwed onto the stud 34, and the inner wall of the through hole is in close contact with the outer wall of the guide post 35.

[0048] In the power generating device according to this embodiment, the studs 34 are installed so that the studs 34 form a screw transmission structure together with the slider structure 32, and the positioning precision and forming precision are high during movement. Furthermore, the provision of the guide posts 35 reduces misalignment and shaking, ensuring accurate and stable linear motion when the slider structure 32 moves, and reducing vibration and noise caused by the movement.

[0049] As shown in Figures 1 and 3, the first drive assembly 3 further includes a first transmission gear 36 and a second transmission gear 37, where the first transmission gear 36 is attached to the drive end of the first drive member 31, the second transmission gear 37 is fitted onto the stud 34, and the second transmission gear 37 and the first transmission gear 36 mesh with each other.

[0050] In the generator of this embodiment, a first transmission gear 36 and a second transmission gear 37 are added, the first transmission gear 36 is attached to the driving end of the first driving member 31, and the second transmission gear 37 is fitted onto the stud 34. The second transmission gear 37 and the first transmission gear 36 mesh with each other, so that the rotational motion of the driving end of the first driving member 31 is converted into linear motion of the stud 34, and when the driving end of the first driving member 31 rotates continuously, continuous linear motion by the stud 34 is ensured.

[0051] Preferably, a first transmission shaft 38 is added between the first transmission gear 36 and the driving end of the first driving member 31, so as to optimize the transmission path for transmitting power to the stud 34 and reduce the energy loss during the power transmission process, which is favorable for improving the transmission efficiency.

[0052] In this embodiment, the types of the first transmission gear 36 and the second transmission gear 37 are not particularly limited.

[0053] In one embodiment, the first transmission gear 36 and the second transmission gear 37 are cylindrical gears, in which case the axial direction of the driving end of the first driving member 31 and the axial direction of the stud 34 are set to be parallel and spaced apart, and the fixed end of the first driving member 31 is attached to the bottom of the support body 1.

[0054] Of course, in another preferred embodiment, as shown in Figures 1 and 3, the type of the first transmission gear 36 and the second transmission gear 37 is bevel gear, and both are located inside the support body 1, in which case the fixed end of the first driving member 31 penetrates the side wall of the support body 1, and its driving end extends to the inside of the support body 1 at the side wall.

[0055] As shown in Figures 1, 3, and 4, the slider structure 32 includes a first slider 321 and a second slider 322, and the limit structures 33 are provided in multiple sets, and the multiple sets of limit structures 33 are attached to at least one of the first slider 321 and the second slider 322.

[0056] In the power generating device of this embodiment, multiple sets of limit structures 33 are attached to at least one of the first slider 321 and the second slider 322, that is, by increasing the number of limit structures 33 and adding corresponding annular groove structures, the load received by each limit structure 33 after installation can be reduced, the transmission relationship between the limit structures 33, the first driving assembly 3, and the fan assembly 2 can be made more reliable, and the movement of the fan assembly 2 can be made more stable.

[0057] When the number of limit structures 33 is two or more, a plurality of sets of limit structures 33 are provided, one set of limit structures 33 being attached to the first slider 321 and the other set of limit structures 33 being attached to the second slider 322.

[0058] Furthermore, when the number of limit structures 33 in each set is two or more, the two or more limit structures 33 in each set are attached in a manner such that they are spaced apart in the axial direction of the support body 1. In this way, a plurality of annular groove structures are also provided, and the number is equal to the greater number of the two sets of limit structures 33. In this case, the plurality of annular groove structures are attached in a manner such that they are spaced apart in the axial direction of the support body 1.

[0059] The first slider 321 is connected to the second slider 322, and one of the first slider 321 and the second slider 322 has a screw hole drilled therein and is screwed onto a stud 34, while the other has a through hole drilled therein and is fitted into a guide post 35. Such a configuration makes it easy for the first slider 321 and the second slider 322 to perform linear motion in synchronization.

[0060] As shown in Figures 1, 3, and 4, the limit structure 33 includes a first connecting rod 331, one end of which is connected to one of the first slider 321 and the second slider 322, and the other end of the first connecting rod 331 extends radially of the support body 1 toward the annular chute structure 22.

[0061] As shown in Figures 2 to 4, the annular chute structure 22 includes an annular chute 221 having an arc-shaped cross section, and the sliding end of the limit structure 33 includes a limit ball 332, which is attached to the other end of the first connecting rod 331, and which has an arc-shaped cross section, and the outer wall of the limit ball 332 is in close contact with the inner wall of the annular chute 221, and which rotates within the annular chute 221 in the circumferential direction of the axis of the support body 1.

[0062] In the power generating device of this embodiment, the cross-section of the annular chute 221 and the cross-section of the limit ball 332 are both arc-shaped. When installing, the limit ball 332 is inserted into the inside of the annular chute 221, and the outer wall of the limit ball 332 is closely attached to the inner wall of the annular chute 221, which is advantageous to convert sliding friction into rolling friction, reduce frictional resistance, and reduce energy loss during the movement process of the limit ball 332, that is, it is advantageous to reduce the loss in the process of the fan assembly 2 rotating to capture wind energy, and improve the conversion efficiency of wind energy.

[0063] In this embodiment, the width size of the opening of the annular chute 221 is equal to the radial size of the limit ball 332, thus making it easy to insert the limit ball 332 into the annular chute 221.

[0064] Furthermore, when mounting, the first sleeve 21 is designed separately. For example, the first sleeve 21 is composed of at least two sub-sleeves, and when the limit ball 332 is mounted on the support body 1, the limit ball 332 is located outside the support body 1. At this time, the limit ball 332 is inserted into the chute of one of the sub-sleeves, and at least two sub-sleeves are joined together, and each chute defines an annular chute 221. The joining method is not limited, and for example, at the joint between two adjacent sub-sleeves, a through hole and a screw hole are drilled in each of the two sub-sleeves, and a bolt is passed through the through hole and screwed into the screw hole until it is tightened.

[0065] Similarly, when inserting the limit structure 33 into the support body 1, first the slider structure 32, the stud 34, and the guide post 35 are attached, and the resulting integrated assembly is inserted inside the support body 1, and the first connecting rod 331 is welded to the slider structure 32 on site, and the limit ball 332 is welded to the first connecting rod 331.

[0066] Of course, the support body 1 may be designed separately and attached by axially joining the open portion of the linear chute 101 and the non-open portion of the linear chute 101. In this case, the limit structure 33 is prefabricated in a factory and inserted into the linear chute 101 through the axial opening of the linear chute 101 on site, and the operation of axially joining the open portion of the linear chute 101 and the non-open portion of the linear chute 101 is also performed on site.

[0067] As shown in Figures 1 and 5, the power generating device further includes a photoelectric conversion member 4 movably attached to the support body 1, and an energy storage member 5 electrically connected to the photoelectric conversion member 4 via a lead wire.

[0068] In the power generation device according to this embodiment, the photoelectric conversion member 4 is added to realize solar energy conversion, and utilization of both wind energy and solar energy is realized, further improving the energy conversion efficiency. Also, compared with single wind power generation, when one energy is insufficient, it can be supplemented by the other energy, ensuring continuous power generation of the system and improving the stability of energy.

[0069] Preferably, the type of the photoelectric conversion member 4 may be a solar cell panel, and the type of the energy storage member 5 may be a storage battery.

[0070] Furthermore, there is no particular limitation on the position at which the photoelectric conversion member 4 is attached. In order to reduce interference with the movement of the fan assembly 2 caused by the attached photoelectric conversion member 4, the photoelectric conversion member 4 is positioned below the fan assembly 2 at a low altitude.

[0071] As shown in FIGS. 1, 5, and 6, the power generating device further includes a connection assembly 6 and a second drive assembly 7. The connection assembly 6 includes a second sleeve 61 fitted into the support body 1 and fixed to the support body 1, and a second connecting rod 62 having one end along its axis attached to the second sleeve 61 and the other end along its axis extending away from the axial direction of the support body 1.
