Description

Technical Field

[0001] This application belongs to the field of photovoltaic technology, and in particular relates to a photovoltaic bracket and a photovoltaic system. Background Technology

[0002] Photovoltaic (PV) mounting systems are an indispensable part of photovoltaic (PV) power generation systems, used to support and fix PV modules. To increase the power generation of PV power plants, PV mounting systems often have solar tracking capabilities, adjusting the angle of the PV modules dynamically to increase the solar radiation received by the modules. However, current PV mounting systems are not only costly to manufacture, complex to install, and difficult to maintain, but also struggle to withstand harsh environments (such as strong winds and extreme weather), affecting their lifespan. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a photovoltaic support structure and photovoltaic system that not only optimizes power generation efficiency but also ensures the stability and reliability of the overall structure of the photovoltaic support structure, while reducing the complexity and maintenance costs of the photovoltaic support structure.

[0004] In a first aspect, this application provides a photovoltaic mounting bracket, comprising:

[0005] Columns;

[0006] A drive mechanism, wherein the fixed end of the drive mechanism is disposed on the column;

[0007] A main shaft is connected to the output end of the drive mechanism, which is adapted to drive the main shaft to rotate about at least one of a first axis and a second axis, wherein the first axis is parallel to the axial direction of the main shaft and the second axis is parallel to the axial direction of the column.

[0008] The support member has two ends that are rotatably connected to the column and the main shaft, respectively, and the extension direction of the support member, the first axis and the second axis intersect each other.

[0009] According to the photovoltaic support structure of this application, on the one hand, the drive mechanism provides rotation of the main shaft around a first axis and a second axis, i.e., the first axis is parallel to the axis of the main shaft, to adjust the tilt angle of the photovoltaic modules installed on the main shaft and optimize the angle between the photovoltaic modules and sunlight; the second axis is parallel to the axis of the column, to adjust the horizontal rotation angle of the photovoltaic modules, so that the photovoltaic modules face the sun as much as possible, realizing dynamic tracking of the sun's position and improving the power generation efficiency of the photovoltaic modules. On the other hand, since the two ends of the support member are connected to the column and the main shaft respectively, and the extension direction of the support member, the first axis, and the second axis intersect each other, the support member is tilted, i.e., a stable triangular structure is formed in space between the support member, the column, and the main shaft, which significantly enhances the overall rigidity and wind resistance of the photovoltaic support structure, enabling it to better adapt to harsh environmental conditions; at the same time, the rotatable connection of the support member to the column and the main shaft can also reduce the interference of the main shaft rotation under the drive mechanism, improving the flexibility and stability of the photovoltaic support structure. In addition, by driving the main shaft to rotate through the drive mechanism, which in turn causes the support component to rotate relative to at least one of the main shaft and the column, the connection method is simplified, and the complexity and maintenance cost of the photovoltaic bracket are reduced.

The end face of the second sub-segment near the first sub-segment abuts against the end face of the first bearing seat near the main shaft.

[0021] According to one embodiment of this application, the first bearing includes at least two first bearing segments sequentially distributed along the circumferential direction; and / or

[0022] The first bearing housing includes two opposing clamping members and two fixing members. The two ends of the two clamping members are detachably connected to the corresponding supporting members through the fixing members.

[0024] According to one embodiment of this application, the first bearing assembly further includes:

[0025] An anti-compression component is sleeved outside the column and located between the first bearing and the first limiting component, the first limiting component being used to support the anti-compression component.

[0056] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0057] The following is for reference. Figures 1-6 The photovoltaic bracket provided in the embodiments of this application is described. The photovoltaic bracket includes a column 100, a drive mechanism 200, a main shaft 300, and a support member 400.

[0058] The fixed end of the drive mechanism 200 is disposed on the column 100; the main shaft 300 is connected to the output end of the drive mechanism 200, and the drive mechanism 200 is adapted to drive the main shaft 300 to rotate about at least one of a first axis and a second axis, the first axis being parallel to the axial direction of the main shaft 300, and the second axis being parallel to the axial direction of the column 100; both ends of the support member 400 are rotatably connected to the column 100 and the main shaft 300 respectively, and the extension direction of the support member 400, the first axis, and the second axis intersect each other. Exemplarily, the outer contour shapes of the main shaft 300 and the support member 400 are, but not limited to, square or circular; the outer contour shape of the column 100 is, but not limited to, circular.

[0059] It should be noted that the first axis is parallel to the horizontal direction, and the second axis is parallel to the vertical direction.

[0060] Understandably, on the one hand, the drive mechanism 200 provides rotation of the main shaft 300 around the first axis and the second axis respectively. That is, the first axis is parallel to the axis of the main shaft 300 to adjust the tilt angle of the photovoltaic module 10 installed on the main shaft 300 and optimize the angle between the photovoltaic module 10 and the sunlight. The second axis is parallel to the axis of the column 100 to adjust the horizontal rotation angle of the photovoltaic module 10, so that the photovoltaic module 10 faces the sun as much as possible, realizing dynamic tracking of the sun's position and improving the power generation efficiency of the photovoltaic module 10. On the other hand, since the two ends of the support member 400 are connected to the column 100 and the main shaft 300 respectively, and the extension direction, the first axis, and the second axis of the support member 400 intersect each other, the support member 400 is tilted. That is, the support member 400, the column 100, and the main shaft 300 form a stable triangular structure in space, which significantly enhances the overall rigidity and wind resistance of the photovoltaic bracket, enabling it to better adapt to harsh environmental conditions. At the same time, the rotatable connection of the support member 400 to the column 100 and the main shaft 300 reduces the interference of the main shaft 300 when it rotates under the drive mechanism 200, improving the flexibility and stability of the photovoltaic bracket. In addition, by having the drive mechanism 200 drive the main shaft 300 to rotate, and simultaneously causing the support member 400 to rotate relative to at least one of the main shaft 300 and the column 100, the connection method is simplified, and the complexity and maintenance cost of the photovoltaic bracket are reduced.

[0061] The photovoltaic support system provided in the embodiments of this application not only optimizes power generation efficiency, but also takes into account the stability and reliability of the overall structure of the photovoltaic support system, and reduces the complexity and maintenance cost of the photovoltaic support system.

[0062] In some embodiments, such as Figures 1 to 3 As shown, the middle part of the spindle 300 is connected to the output end of the drive mechanism 200, and at least one support member 400 is provided between the end of the spindle 300 and the middle part of the spindle 300.

[0063] Understandably, considering the relatively long overall length of the main shaft 300, connecting its middle section to the output end of the drive mechanism 200 ensures efficient and stable power transmission. Simultaneously, at least one support member 400 is provided between both ends and the middle of the main shaft 300, enhancing the overall stability of the photovoltaic support structure and providing additional support for the photovoltaic module 10, thereby improving the load-bearing capacity and structural stability of the main shaft 300.

[0064] In some embodiments, such as Figures 1 to 3As shown, the spindle 300 includes two sequentially arranged main body sections. The ends of the two main body sections, close to each other, are connected to the drive mechanism 200. Each main body section is provided with at least one support member 400 to improve the overall load-bearing capacity of the spindle 300. The connection direction between the main body sections and the drive mechanism 200 includes, but is not limited to, threaded connections. It should be noted that the number, size, and specific distribution of the support members 400 can be designed according to actual needs, and this embodiment does not impose specific limitations in this regard.

[0065] In some embodiments, such as Figure 1 As shown, the two support members 400 are symmetrically arranged relative to the column 100; the photovoltaic bracket also includes a first bearing assembly 500, which is disposed between the support member 400 and the column 100 and connected to the support member 400, and is suitable for driving the support member 400 to rotate relative to the column 100.

[0066] Understandably, on the one hand, the symmetrical arrangement of the two support members 400 with the column 100 as the axis of symmetry enhances the overall stability of the photovoltaic support structure and reduces local stress concentration through reasonable mechanical distribution. On the other hand, the first bearing assembly 500 enables the rotation of the two symmetrically arranged support members 400 around the second axis, and its low-friction characteristics reduce energy loss during the movement of the photovoltaic support structure, improving the operating efficiency of the photovoltaic system. Furthermore, since the first bearing assembly 500 can drive all support members 400 to rotate synchronously, it ensures the overall stability of the support members 400 during movement, reduces structural stress concentration caused by inconsistent local rotation, and extends the service life of the photovoltaic support structure.

[0067] In some embodiments, such as Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the first bearing assembly 500 includes a first bearing 510 and a first bearing housing 520; the first bearing housing 520 is connected to each support member 400; wherein,

[0068] The first bearing 510 is rotatably sleeved outside the column 100; and / or

[0069] The first bearing housing 520 and the first bearing 510 slide together along the circumference of the column 100.

[0070] Exemplarily, the first bearing housing 520 and the first bearing 510 may have cylindrical or conical inner holes for respectively mate with the outer rings of the first bearing 510 and the column 100; the outer contour of the first bearing housing 520 may be square, circular, or other shapes; the outer contour of the first bearing 510 may be circular. The materials of the first bearing housing 520 and the first bearing 510 may include, but are not limited to, metal or plastic materials. The metal materials may include, but are not limited to, high-carbon chromium bearing steel, stainless steel, cast iron, or aluminum-based alloys, and the plastic materials may include, but are not limited to, acetal, polyetheretherketone, polyoxymethylene, polytetrafluoroethylene, or phenolic resin. This embodiment does not impose specific limitations on these materials.

[0071] It is understood that the first bearing 510 is mounted on the outside of the column 100 to provide low-friction rotational support for the first bearing housing 520 and to limit its movement along the axial direction of the column 100. The first bearing housing 520 is connected to each support member 400, and at least one of the following methods is used to achieve synchronous rotation of each support member 400 relative to the column 100: rotation of the first bearing 510 relative to the column 100 and sliding engagement of the first bearing housing 520 and the first bearing 510 in the circumferential direction. It should be noted that the first bearing housing 520 and the first bearing 510 may be relatively fixed, while the first bearing 510 and the column 100 may rotate relative to each other; or the first bearing housing 520, the first bearing 510, and the column 100 may all rotate relative to each other; or the first bearing housing 520 and the first bearing 510 may rotate relative to each other, while the first bearing 510 and the column 100 may be relatively fixed. This embodiment does not impose specific limitations on these methods.

[0072] In some embodiments, such as Figures 4 to 6 As shown, the first bearing 510 includes a first segment 5111 and a second segment 5112. The first segment 5111 is located between the column 100 and the first bearing housing 520. The second segment 5112 is disposed at the end of the first segment 5111 away from the main shaft 300, and the outer diameter of the second segment 5112 is larger than the outer diameter of the first segment 5111. The end face of the second segment 5112 near the first segment 5111 abuts against the end face of the first bearing housing 520 near the main shaft 300. It should be noted that the shaft lengths of the first segment 5111 and the second segment 5112 can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0073] Understandably, the first segment 5111 and the second segment 5112 are connected sequentially from top to bottom, and the outer diameter of the second segment 5112 is larger than the outer diameter of the first segment 5111. This creates a step between the lower end face of the first segment 5111 and the upper end face of the second segment 5112, allowing the first bearing housing 520 to be directly supported on the upper end face of the second segment 5112. This not only provides a larger contact area, enhancing the load-bearing capacity and impact resistance of the first bearing assembly 500, but also provides stable support and axial limiting.

[0074] It should be noted that when the first bearing 510 and the first bearing housing 520 rotate relative to each other, the upper end face of the second sub-segment 5112 and the lower end face of the first bearing housing 520 slide against each other.

[0075] In some embodiments, such as Figure 5 and Figure 6 As shown, the first bearing 510 includes at least two first bearing segments distributed sequentially along the circumference, that is, the first bearing 510 has a split structure, which not only facilitates the assembly between the first bearing 510 and the column 100, but also distributes the load and improves the service life and reliability of the first bearing 510.

[0076] For example, in this embodiment, such as Figure 5 and Figure 6 As shown, there are two first bearing sections. The first bearing section is generally semi-cylindrical. The two first bearing sections can be spliced ​​end to end to form a first bearing 510 that is closed around the circumference of the column 100, or they can be spaced apart to form a first bearing 510 with a split structure, so as to reduce manufacturing costs while adapting to columns 100 with different outer diameters.

[0077] It should be noted that, since at least two first bearing segments are sequentially distributed along the circumference of the column 100 to form the first bearing 510, each first bearing segment includes a first sub-segment 5111 and a second sub-segment 5112. The first sub-segment 5111, the second sub-segment 5112 and the first bearing segment correspond one-to-one, so as to maximize the contact area between the first bearing 510 and the first bearing housing 520, thereby improving the overall reliability of the first bearing assembly 500.

[0078] In some embodiments, such as Figures 4 to 6 As shown, the first bearing housing 520 includes two opposing clamping members 521 and two fixing members 522. The two ends of the two clamping members 521 are detachably connected to the corresponding support members 400 through the fixing members 522. The fixing members 522 include, but are not limited to, bolts or screws.

[0079] Understandably, the first bearing housing 520 is designed as a separate unit using the fastener 522 and the clamp 521 to facilitate disassembly and maintenance. Furthermore, the fastener 522 not only accommodates first bearings 510 with different outer diameters but also allows adjustment of the preload between the two clamps 521, ensuring the reliability and stability of the first bearing housing 520.

[0080] In some embodiments, such as Figures 4 to 6 As shown, a first limiting member 600 is provided on the outside of the column 100 to support the first bearing assembly 500. Specifically, the first bearing 510 is disposed on the first limiting member 600, thereby increasing the contact area and improving the stability and load-bearing capacity of the support member 400 rotating on the column 100. The shape of the first limiting member 600 includes, but is not limited to, a circular or square ring. The connection method between the first limiting member 600 and the column 100 includes, but is not limited to, threaded connection, welding, or snap-fit. The pressure-resistant member 530 includes, but is not limited to, a pressure-resistant bearing.

[0081] In some embodiments, such as Figures 4 to 6 As shown, the first bearing assembly 500 also includes a pressure-resistant member 530, which is sleeved outside the column 100 and located between the first bearing 510 and the first limiting member 600. The first limiting member 600 is used to support the pressure-resistant member 530. It can be understood that the first bearing 510, the pressure-resistant member 530, and the first limiting member 600 are arranged sequentially from top to bottom. The cooperation between the pressure-resistant member 530 and the first limiting member 600 improves the stability and load-bearing capacity of the support member 400 rotating on the column 100, and also assists the rotation of the first bearing 510, reducing the friction generated during relative rotation when the first bearing 510 is directly mounted on the first limiting member 600.

[0082] In some embodiments, such as Figures 4 to 6 As shown, the pressure-resistant component 530 includes a pressure-resistant ball bearing. Specifically, the pressure-resistant ball bearing comprises a first ring body, multiple rolling elements, and a second ring body arranged sequentially along the direction close to the first limiting member 600. When the first bearing 510 rotates relative to the column 100, friction and the rolling elements drive the first ring body to rotate synchronously. Simultaneously, the friction between the second ring body and the first limiting member 600 fixes the second ring body and the first limiting member 600 relative to each other, thereby allowing the pressure-resistant component 530 to be partially rotated and sleeved outside the column 100. The rolling elements include, but are not limited to, balls or rollers. Of course, in other embodiments, the entire pressure-resistant component 530 may rotate relative to the first limiting member 600, or the entire pressure-resistant component 530 may be fixed relative to the first limiting member 600; this embodiment does not impose specific limitations on this.

[0083] In some embodiments, when the first bearing 510 rotates relative to the column 100, the coefficient of friction between the anti-pressure member 530 and the first bearing 510 is less than the coefficient of friction between the anti-pressure member 530 and the first limiting member 600, ensuring that the first bearing 510 can operate with lower energy loss during rotation. This helps to improve the overall efficiency of the photovoltaic support and enhances the axial stability and limiting effect of the anti-pressure member 530, reducing unnecessary movement during operation.

[0084] In some embodiments, such as Figure 4 As shown, a second limiting member 700 is provided outside the column 100. The first bearing assembly 500 is located between the first limiting member 700 and the second limiting member 700. The ends of the second limiting member 700 and the first bearing assembly 500 that are close to each other are spaced apart to reduce interference when the first bearing assembly 500 rotates at least partially relative to the column 100. The shape of the second limiting member 700 includes, but is not limited to, a circular ring or a square ring. The connection method between the second limiting member 700 and the column 100 includes, but is not limited to, threaded connection, welding, or snap-fit.

[0085] In some embodiments, such as Figure 1 As shown, the photovoltaic support also includes connectors 900, which extend axially along the main shaft 300 and are connected to the supports 400 one by one. The connection methods between the connectors 900 and the supports 400 include, but are not limited to, threaded connection, welding, or snap-fit.

[0086] Understandably, the connector 900 extends axially along the main shaft 300 and connects to the two support members 400 respectively, forming a stable connection. This reduces vibration and deformation of the support members 400 caused by external forces (such as wind), and evenly transfers the load on the support members 400 to the main shaft 300, reducing local stress concentration and extending the service life of the photovoltaic support system. Simultaneously, it ensures that each support member 400 moves synchronously when the main shaft 300 rotates, improving the operating efficiency of the photovoltaic support system.

[0087] In some embodiments, such as Figure 2 and Figure 3 As shown, the connector 900 includes two opposing mounting strips 910, with the column 100 located between the two mounting strips 910 to enhance the stability of the photovoltaic support and ensure its reliability under dynamic and static conditions. The mounting strips 910 include, but are not limited to, channel steel. It should be noted that the shape, material, size, and specific distribution of the mounting strips 910 can be designed according to actual needs, and this embodiment does not impose specific limitations in this regard.

[0088] In some embodiments, such as Figure 1 and Figure 2As shown, the photovoltaic support also includes a second bearing assembly 800, which is disposed between the main shaft 300 and the support member 400 and is suitable for driving the support member 400 to rotate synchronously relative to the main shaft 300 around the first axis.

[0089] It is understandable that the second bearing assembly 800 enables the main shaft 300 to rotate relative to each support member 400 around the first axis, and its low friction characteristics can reduce energy loss during the movement of the photovoltaic bracket and improve the operating efficiency of the photovoltaic system.

[0090] In some embodiments, such as Figure 3 As shown, the second bearing assembly 800 includes a second bearing housing 820 and a second bearing 810. The second bearing housing 820 is connected to the support member 400. The second bearing 810 is pivotally mounted on the second bearing housing 820 and sleeved on the outside of the main shaft 300, thereby realizing relative rotation between the main shaft 300 and the support member 400 around the first axis.

[0091] Exemplarily, the second bearing housing 820 and the second bearing 810 may have cylindrical or conical inner holes for respectively mate with the outer ring of the second bearing 810 and the main shaft 300; the outer contour of the second bearing 810 may be square, circular, or other shapes. The materials of the second bearing housing 820 and the second bearing 810 may include, but are not limited to, metal or plastic materials. The metal materials may include, but are not limited to, high-carbon chromium bearing steel, stainless steel, cast iron, or aluminum-based alloys, while the plastic materials may include, but are not limited to, acetal, polyetheretherketone, polyoxymethylene, polytetrafluoroethylene, or phenolic resin. This embodiment does not impose specific limitations on these materials.

[0092] In some embodiments, such as Figure 3 As shown, the second bearing 810 includes at least two second bearing segments sequentially distributed circumferentially along the main shaft 300. That is, the second bearing 810 has a split structure, which not only facilitates the assembly between the second bearing 810 and the main shaft 300, but also distributes the load and improves the service life and reliability of the second bearing 810.

[0093] For example, in this embodiment, such as Figure 3 As shown, there are two second bearing sections, which are generally semi-cylindrical. The two second bearing sections can be spliced ​​end to end to form a second bearing 810 that is closed in the circumferential direction, or they can be spaced apart to form a second bearing 810 with a split structure, so as to reduce manufacturing costs while adapting to spindles 300 with different outer diameters.

[0094] In some embodiments, the drive mechanism 200 includes a dual-axis reducer, which has two output shafts to drive the main shaft 300 to rotate in both directions around the first axis and the second axis. This reduces the number and complexity of the photovoltaic support structure, making it as compact as possible. Of course, in other embodiments, the drive mechanism 200 may also use two single-axis motors to drive the main shaft 300 to rotate in both directions around the first axis and the second axis respectively. This embodiment does not impose specific limitations on this.

[0095] This application also provides a photovoltaic system. For example... Figure 1 As shown, the photovoltaic system includes a photovoltaic module 10 and the aforementioned photovoltaic bracket, with the photovoltaic module 10 mounted on the main shaft 300 of the photovoltaic bracket.
