Description

Technical Field

[0001] This utility model relates to the field of photovoltaic system technology, specifically to a foldable dual-axis photovoltaic tracking device. Background Technology

[0002] With the development of the photovoltaic industry, foldable photovoltaic devices have been widely used due to their flexible layout. These devices typically use a drive mechanism to fold up the photovoltaic components and attach them to the side of the pole when not in operation, and make the light-receiving surface of the first photovoltaic module close to the light-receiving surface of the second photovoltaic module, thereby reducing the wind-receiving area of ​​the photovoltaic components, significantly reducing wind load, and improving the ability to resist severe weather.

[0003] However, when photovoltaic (PV) devices are folded, the hinge points between the PV components and the pole, as well as the hinge points between the first and second PV modules, are prone to swaying under wind or other external disturbances. Long-term, repeated swaying not only affects the structural lifespan but may also cause fatigue or even damage to the connecting structures, posing safety hazards. Improving the stability of PV devices in the folded state is a pressing issue that needs to be addressed. Utility Model Content

[0009] The second drive mechanism is connected to the output end of the first drive mechanism and is driven by the first drive mechanism to rotate around the axis of the first drive mechanism.

[0010] A photovoltaic component is connected to the second drive mechanism and is driven by the second drive mechanism to rotate around the axis of the second drive mechanism;

[0017] Optionally, the support portion is a cushioning pad.

[0018] Optionally, the photovoltaic tracking module further includes:

[0019] A clutch mechanism includes a first clutch component and a second clutch component. The second clutch component is connected to the output end of a second drive mechanism. The clutch mechanism has a switchable engaged state and a disengaged state. When the clutch mechanism is in the engaged state, the second drive mechanism drives the first clutch component and the second clutch component to rotate relative to each other around the axis of the second drive mechanism. When the clutch mechanism is in the disengaged state, the second drive mechanism drives the second clutch component to rotate relative to the first clutch component around the axis of the second drive mechanism.

[0020] The photovoltaic component includes a first photovoltaic module and a second photovoltaic module, wherein the first photovoltaic module is connected to the first clutch and the second photovoltaic module is connected to the second clutch;

[0021] In the folded state, under the action of the second drive mechanism and the clutch mechanism, the light-receiving surface of the first photovoltaic module is brought close to the light-receiving surface of the second photovoltaic module;

[0022] The support assembly further includes a second support member for maintaining the spacing of the second photovoltaic module, the second support member being connected to the first photovoltaic module and / or the second photovoltaic module.

[0023] Optionally, the first photovoltaic module includes a first photovoltaic panel and a first frame surrounding the side of the first photovoltaic panel, and the second photovoltaic module includes a second photovoltaic panel and a second frame surrounding the side of the second photovoltaic panel.

[0024] Optionally, the second support member is detachably connected to the first frame, and / or the second support member is detachably connected to the second frame.

[0025] Optionally, the first photovoltaic module is provided with at least one second support member, which is connected to the first frame.

[0029] First, when the dual-axis photovoltaic tracking device of this utility model is in the folded state, the second drive mechanism and the photovoltaic component are folded to one side of the column. By setting a first support member, the distance between the second drive mechanism and the column is maintained. When the dual-axis photovoltaic tracking device is in the folded state, the first support member restricts the swaying of the second drive shaft. At the same time, the first support member absorbs the vibration of the second drive shaft caused by wind or other external disturbances, thereby increasing the stability of the foldable dual-axis photovoltaic tracking device in the folded state and increasing the service life of the structure.

[0030] Secondly, by placing the first support member on the column, this invention reduces the weight of the photovoltaic tracking module, thereby reducing the energy consumption required to drive it for tracking. It also avoids affecting the unfolding and folding of the first and second photovoltaic modules, increasing the smoothness of their operation. Furthermore, a connecting seat is provided on the column, allowing the first support member to be detachably connected to it, facilitating subsequent maintenance or replacement.

[0031] Third, when the dual-axis photovoltaic tracking device is in the folded state, the light-receiving surface of the first photovoltaic module is close to the light-receiving surface of the second photovoltaic module. By setting a second support member, the distance between the first and second photovoltaic modules is maintained. When the dual-axis photovoltaic tracking device is in the folded state, the second support member restricts the relative sway between the second and first photovoltaic modules. At the same time, the second support member absorbs the vibration between the second and first photovoltaic modules caused by wind or other external disturbances, thereby further increasing the stability of the foldable dual-axis photovoltaic tracking device in the folded state and increasing the service life of the structure.

[0032] Fourth, by connecting the second support to the first and second frames, damage to the first and second photovoltaic panels can be prevented. Furthermore, the second support is detachable, facilitating future maintenance or replacement. Additionally, the second support is located at the four corners of the first and second frames, providing stable support between the first and second photovoltaic modules when they are folded, further increasing the stability of the dual-axis photovoltaic tracking device in its folded state.

[0047] like Figures 1 to 5 As shown, this embodiment discloses a foldable dual-axis photovoltaic tracking device, including a column 200 and at least one set of photovoltaic tracking components 100;

[0048] The photovoltaic tracking module 100 includes:

[0049] The first drive mechanism 1 is connected to the column 200;

[0050] The second drive mechanism 2 is connected to the output end of the first drive mechanism 1 and is driven by the first drive mechanism 1 to rotate around the axis of the first drive mechanism 1.

[0051] A photovoltaic component is connected to the second drive mechanism 2 and is driven by the second drive mechanism 2 to rotate around the axis of the second drive mechanism 2;

[0052] The photovoltaic tracking component 100 has a folded state. In the folded state, the first drive mechanism 1 drives the second drive mechanism 2 and the photovoltaic component to fold to one side of the column 200.

[0053] The photovoltaic tracking component 100 further includes a support component, which includes a first support member 61 for maintaining the distance between the second drive mechanism 2 and the column 200. The first support member 61 is connected to the column 200 and / or the photovoltaic tracking component 100.

[0054] It should be noted that, in this embodiment, the first driving mechanism 1 and the second driving mechanism 2 are used to drive the photovoltaic component to rotate in space, so that the light-receiving surface of the photovoltaic component faces the sun, and the sunlight is as perpendicular as possible to the light-receiving surfaces of the first photovoltaic module 4 and the second photovoltaic module 5, thereby improving the power generation efficiency of the photovoltaic tracking device. In this embodiment, the first driving mechanism 1 is used to drive the second driving mechanism 2 to rotate around the axis of the first driving mechanism 1, and the second driving mechanism 2 is used to drive the photovoltaic component to rotate, so that the photovoltaic component can be adjusted in two directions. Based on satisfying the functions of the first driving mechanism 1 and the second driving mechanism 2, those skilled in the art can achieve the same purpose of this application by only changing the specific structure of the first driving mechanism 1 and the second driving mechanism 2 without creative effort, and should be considered within the protection scope of this application.

[0055] It should be noted that, in this embodiment, the photovoltaic tracking module 100 further includes:

[0056] The clutch mechanism 3 includes a first clutch component and a second clutch component. The second clutch component is connected to the output end of the second drive mechanism 2. The clutch mechanism 3 has a switchable engaged state and a disengaged state. When the clutch mechanism 3 is in the engaged state, the second drive mechanism 2 drives the first clutch component and the second clutch component to rotate relative to each other around the axis of the second drive mechanism 2. When the clutch mechanism 3 is in the disengaged state, the second drive mechanism 2 drives the second clutch component to rotate relative to the first clutch component around the axis of the second drive mechanism 2.

[0057] The photovoltaic component includes a first photovoltaic module 4 and a second photovoltaic module 5, wherein the first photovoltaic module 4 is connected to the first clutch and the second photovoltaic module 5 is connected to the second clutch;

[0058] In the folded state, under the action of the second driving mechanism 2 and the clutch mechanism 3, the light-receiving surface of the first photovoltaic module 4 is driven to come close to the light-receiving surface of the second photovoltaic module 5;

[0059] The support assembly further includes a second support member 62 for maintaining the distance between the first photovoltaic module 4 and the second photovoltaic module 5, the second support member 62 being connected to the first photovoltaic module 4 and / or the second photovoltaic module 5.

[0060] It should be noted that, in this embodiment, the clutch mechanism 3 refers to a combination capable of switching between an engaged state and a disengaged state. Specifically, it includes a second clutch component fixed relative to the output end of the second drive mechanism 2, and a first clutch component capable of switching states relative to the second clutch component. To enable the clutch mechanism 3 to switch between engaged and disengaged states, the specific structures and connection methods of the first and second clutch components of the clutch mechanism 3 include, but are not limited to, the following: For example, a pawl and a ratchet are respectively provided on the first and second clutch components. When the pawl and ratchet are engaged, the clutch mechanism 3 is in the engaged state, and when the pawl and ratchet are not engaged, the clutch mechanism 3 is in the disengaged state. Another example is that a movable pin is provided on the second clutch component. The movement of the movable pin allows the first clutch component to be restricted or released, thereby achieving the switching between the engaged and disengaged states. Therefore, those skilled in the art who, without inventive effort, merely change the specific structure of the clutch mechanism 3 to achieve the same purpose as this application should be considered within the scope of protection of this application.

[0061] It should be noted that, in this embodiment, as Figure 2 , Figure 3 and Figure 5 As shown, the first support member 61 is used to support the second drive mechanism 2 and the column 200, and to maintain the distance between the second drive mechanism 2 and the column 200. When the first drive mechanism 1 drives the second drive mechanism 2 to fold to one side of the column 200, it prevents the second drive mechanism 2 from shaking around the first drive mechanism 1, thereby increasing the stability of the photovoltaic component connected to the second drive mechanism 2 relative to the column 200 and increasing the stability of the dual-axis photovoltaic tracking device in the folded state.

[0062] Furthermore, in this embodiment, there is at least one first support member 61. When there is only one first support member 61, it is connected to the column 200 or the photovoltaic component. When there are multiple first support members 61, all of them can be connected to the column 200, all of them can be connected to the photovoltaic component, or a portion can be connected to the column 200 and another portion can be connected to the photovoltaic component. To facilitate the connection of the first support member 61 to the corresponding component, the first support member 61 includes a support portion and a connecting portion disposed at one end of the support portion. The support portion is detachably connected to the corresponding component through the connecting portion.

[0063] Furthermore, in this embodiment, the first support member 61 can be connected to the photovoltaic tracking component 100, that is, connected to the second drive mechanism 2, the clutch mechanism 3, or the photovoltaic component. In this case, the connecting seat is located at the corresponding position on the column 200; however, to avoid affecting the photovoltaic tracking operation of the photovoltaic component, such as Figure 2 , Figure 3 and Figure 5As shown, the first support member 61 is connected to the column 200, and the column 200 is provided with a connecting seat that mates with the connecting part. The mate between the connecting part and the connecting seat includes, but is not limited to, the following: for example, the connecting part is a mounting bolt located at one end of the support part, and the column 200 is provided with a mounting screw hole that mates with the mounting bolt.

[0064] Furthermore, in this embodiment, while fulfilling the function of the first support member 61, the first support member 61 can be made of a rigid material, a flexible material, or a material with both flexible and rigid structures. For example, in the first support member 61, the part used to connect to the outside, that is, the connecting part, is made of a rigid material, while the part used to abut against the outside is made of a flexible material. Figure 2 , Figure 3 and Figure 5 The first support member 61 shown in the image is a cushioning pad.

[0065] It should be noted that, in this embodiment, as Figures 1 to 5 As shown, the second support member 62 is used to support the first photovoltaic module 4 and the second photovoltaic module 5, and to maintain the distance between the first photovoltaic module 4 and the second photovoltaic module 5. When the light-receiving surface of the first photovoltaic module 4 is close to the light-receiving surface of the second photovoltaic module 5, it can prevent the first photovoltaic module 4 from shaking relative to the second photovoltaic module 5, thereby increasing the stability of the photovoltaic components and further increasing the stability of the dual-axis photovoltaic tracking device in the folded state.

[0066] Furthermore, in this embodiment, to facilitate the connection of the second support member 62 to the first photovoltaic module 4 or the second photovoltaic module 5, such as... Figures 1 to 5 As shown, the first photovoltaic module 4 includes a first photovoltaic panel 41 and a first frame 42 surrounding the side of the first photovoltaic panel 41. The second photovoltaic module 5 includes a second photovoltaic panel 51 and a second frame 52 surrounding the side of the second photovoltaic panel 51. To avoid damage to the first photovoltaic panel 41 or the second photovoltaic panel 51, the second support member 62 is detachably connected to the first frame 42, and similarly, the second support member 62 is detachably connected to the second frame 52. Specifically, it can be fixed to the first frame 42 or the second frame 52 with bolts, or it can be engaged with the first frame 42 or the second frame 52 by providing a locking groove.

[0067] Furthermore, in this embodiment, there is at least one second support member 62. When there is only one second support member 62, the second support member 62 is connected to the first photovoltaic module 4 or the second photovoltaic module 5. When there are multiple second support members 62, all of the second support members 62 can be connected to the first photovoltaic module 4, all of them can be connected to the second photovoltaic module 5, or a portion can be connected to the first photovoltaic module 4 and another portion can be connected to the second photovoltaic module 5.

[0068] Furthermore, in this embodiment, to further increase the stability between the first photovoltaic module 4 and the second photovoltaic module 5, and to maintain a stable distance between them so that they do not wobble relative to each other, the specific implementation includes, but is not limited to, the following: The number of second support members 62 on the first photovoltaic module 4 is four, and the four second support members 62 are located at the four corners of the first frame 42. The second support members 62 on the first photovoltaic module 4 can directly abut against the frame of the second photovoltaic module 5, or they can be arranged as follows: Figures 1 to 5 As shown, four second support members 62 are provided on the second photovoltaic module 5. The four second support members 62 are located at the four corners of the second frame 52, so that the second support members 62 on the first photovoltaic module 4 abut against the second support members 62 on the second photovoltaic module 5.

[0069] Furthermore, in this embodiment, while fulfilling the function of the second support member 62, the second support member 62 can be made of a rigid material, a flexible material, or a material with both flexible and rigid structures. For example, in the second support member 62, the part used to connect to the outside and the part used to abut against the outside are made of a flexible material. Figures 2 to 5 As shown, the second support member 62 is a corner protector.

[0070] The advantages of this embodiment are: it increases the stability of the dual-axis photovoltaic tracking device in the folded state, and facilitates the maintenance or replacement of the first support member 61 and the second support member 62.

[0071] First, when the dual-axis photovoltaic tracking device of this utility model is in the folded state, the second drive mechanism 2 and the photovoltaic component are folded to one side of the column 200. By setting the first support member 61, the distance between the second drive mechanism 2 and the column 200 is maintained. When the dual-axis photovoltaic tracking device is in the folded state, the first support member 61 restricts the swaying of the second drive shaft. At the same time, the first support member 61 absorbs the vibration of the second drive shaft caused by wind or other external disturbances, thereby increasing the stability of the foldable dual-axis photovoltaic tracking device in the folded state and increasing the service life of the structure.

[0072] Secondly, by placing the first support member 61 on the column 200, this embodiment reduces the weight of the photovoltaic tracking module 100, thereby reducing the energy consumption required to drive the photovoltaic tracking module 100 to perform photovoltaic tracking. Simultaneously, it avoids affecting the unfolding and folding of the first photovoltaic module 4 and the second photovoltaic module 5, increasing the smoothness of their unfolding and folding operations. Furthermore, a connecting seat is provided on the column 200, allowing the first support member 61 to be detachably connected to the column 200, facilitating subsequent maintenance or replacement of the first support member 61.

[0073] Third, when the dual-axis photovoltaic tracking device is in the folded state, the light-receiving surface of the first photovoltaic module 4 is close to the light-receiving surface of the second photovoltaic module 5. By setting the second support member 62, the distance between the first photovoltaic module 4 and the second photovoltaic module 5 is maintained. When the dual-axis photovoltaic tracking device is in the folded state, the second support member 62 restricts the relative sway between the second photovoltaic module 4 and the first photovoltaic module 5. At the same time, the second support member 62 absorbs the vibration between the second photovoltaic module 5 and the first photovoltaic module 4 caused by wind or other external disturbances, thereby further increasing the stability of the foldable dual-axis photovoltaic tracking device in the folded state and increasing the service life of the structure.

[0074] Fourth, by connecting the second support member 62 to the first frame 42 and the second frame 52, damage to the first photovoltaic panel 41 and the second photovoltaic panel 51 can be prevented. Furthermore, the second support member 62 is detachable, facilitating subsequent maintenance or replacement. Additionally, the second support member 62 is located at the four corners of the first frame 42 and the second frame 52, providing stable support between the first photovoltaic module 4 and the second photovoltaic module 5 when they are in the folded state, further increasing the stability of the dual-axis photovoltaic tracking device in the folded state.
