Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic brackets, and in particular to a bearing assembly and a photovoltaic bracket. Background Art

[0002] Currently, in the photovoltaic mounting industry, a combination of a main beam and a synchronous shaft is commonly used to drive the rotation of photovoltaic panels. In the multi-point synchronous drive systems currently available for photovoltaic mountings, when the distance between two adjacent drive points is large, the synchronous shaft deforms severely during rotation, and the deflection increases. The greater the distance between two adjacent drive points, the more severe the deflection of the synchronous shaft. This can lead to uneven force at the power output end of the drive points during rotation, causing jamming, affecting power transmission efficiency, and in severe cases, damaging the drive device, rendering the photovoltaic mounting system inoperable.

[0010] In some embodiments, the first seat body or the second seat body is provided with a connecting portion suitable for mounting the bearing seat on a column top seat.

[0011] In some embodiments, the connection structure includes a fastening hole and a fastener arranged corresponding to the fastening hole, the fastening hole is located on the circumferential side of the first mounting hole of the first base body, and on the circumferential side of the second mounting hole of the second base body; the fastener passes through the fastening hole on the first base body and the fastening hole on the second base body to achieve connection between the first base body and the second base body.

[0013] In some embodiments, the first seat body has an annular rib extending from the edge of the first mounting hole in a direction away from the second seat body, and the second seat body has an annular rib extending from the edge of the second mounting hole in a direction away from the first seat body; the two annular ribs are used to limit the axial egress of the spherical bearing along the first mounting hole and the second mounting hole.

[0014] In some embodiments, the inner wall of the annular rib is spherical in structure to fit the outer wall of the spherical bearing.

[0015] In some embodiments, the spherical bearing adopts a split structure, including a first split body and a second split body;

[0016] The first split body and the second split body are radially connected to form a whole adapted to the outer wall surface of the synchronization shaft in the circumferential direction.

[0021] The present application has at least one of the following beneficial effects:

[0022] 1. In this application, the bearing assembly adopts a structural setting of a spherical bearing and a split bearing seat.

[0023] 2. This application uses a split bearing seat, in which the first and second seats are fixedly connected by a connecting structure, enabling the pre-installation of the entire bearing assembly. This allows the user to simply install the pre-installed bearing assembly onto the column during on-site installation, making installation more convenient and significantly reducing on-site construction and installation efforts. Furthermore, compared to the installation method in which both the first and second seats are mounted to the column via fasteners, this application's method of mounting the entire bearing assembly onto the column requires fewer installation nodes and fewer fasteners, making it more convenient for on-site installation and requiring less assembly time, saving manpower and material resources.

[0024] 3. In the present application, since the first seat body and the second seat body can be pre-installed through a connecting structure, it is only necessary to set a connecting portion for docking the column on the first seat body or the second seat body to achieve the connection between the entire bearing assembly and the column. Compared with the existing technology in which both split bodies of the split bearing seat are provided with a connecting portion and are fixedly connected to the column, the bearing assembly in the present application has less material cost and fewer fasteners required for on-site installation, which is conducive to saving on-site installation time.

[0025] 4.

When the claw passes through the slot, the claw is deformed by using an external tool, and the claw will no longer fall out, thereby realizing the connection between the first base body and the second base body, eliminating fasteners, further reducing the number of fasteners, and making installation more convenient and quick.

[0046] In the embodiments shown in the accompanying drawings, directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of various components of the present application are not absolute but relative. These descriptions are applicable when these components are in the positions shown in the accompanying drawings. If the descriptions of the positions of these components are changed, these directional indications will also change accordingly.

[0047] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0048] According to a specific embodiment provided by this application, see Figures 1 to 3 , discloses a bearing assembly for use in a photovoltaic mount, comprising a bearing housing 100 and a spherical bearing 200. The bearing housing 100 has a mounting hole for mounting the spherical bearing 200, and the wall of the mounting hole provides support for the spherical bearing 200, allowing the spherical bearing 200 to rotate about the axis of the mounting hole. Conversely, the spherical bearing 200 has a bearing hole 230 for receiving a synchronization shaft 302 of the photovoltaic mount.

[0049] This embodiment uses a spherical bearing 200, which rotates more smoothly compared to conventional cylindrical bearings. It can not only provide upward support force for the synchronization shaft 302 and reduce the deflection and deformation of the synchronization shaft 302, but also improve the jamming phenomenon of the synchronization shaft 302, making the synchronization shaft 302 rotate more smoothly and ensuring the synchronization of power transmission between the main shaft of the photovoltaic bracket and the synchronization shaft 302.

[0050] In one example embodiment, see Figure 3 and Figure 4 The bearing housing 100 adopts a split structure in the axial direction, which is more conducive to the installation of the ball bearing 200. Specifically, the bearing housing 100 includes a first housing 110 and a second housing 120. The first housing 110 is provided with a first mounting hole 111, and the second housing 120 is provided with a second mounting hole 121. When the first housing 110 and the second housing 120 are in contact with each other, the first mounting hole 111 and the second mounting hole 121 are coaxial, forming the aforementioned mounting hole to carry and support the ball bearing 200 for rotation around the axis of the first mounting hole 111 and the second mounting hole 121.

[0051] Preferably, the first base 110 and the second base 120 are fixedly connected by a connection. This allows the user to pre-assemble the bearing assembly. During on-site installation, the pre-assembled bearing assembly can be directly installed on the column, making installation more convenient and reducing on-site installation work. Furthermore, in actual production, the entire assembly can be pre-assembled in the factory and shipped pre-assembled, further reducing the user's installation time and enhancing practicality.

[0052] Further, see Figure 2 and Figure 3The first seat body 110 or the second seat body 120 is provided with a connecting portion 130 suitable for installing the bearing seat 100 on the column top seat 301. In this embodiment, because the first seat body 110 and the second seat body 120 can be pre-installed through the pre-tightening structure, it is only necessary to provide the connecting portion 130 for docking with the column top seat 301 on the first seat body 110 or the second seat body 120 to achieve the connection between the entire bearing assembly and the column. Compared with the existing method of providing a connecting portion 130 for fixed connection between the two split bodies of the split bearing seat 100 and the column, the bearing assembly in this application has less material cost, a simpler structural setting, and fewer fasteners 402 required for on-site installation, which is conducive to saving on-site installation time.

[0053] Specifically, the connecting portion 130 has two fastening holes 401 through which fasteners 402 pass to secure the connecting portion 130 to the column top seat 301. Fasteners 402 are preferably bolts, which facilitate easy assembly and disassembly of the bearing assembly. During on-site installation, users only need to use these two bolts to secure the bearing assembly to the column top seat 301, reducing the number of installation nodes and significantly reducing on-site installation workload.

[0054] In one embodiment, see Figure 3 and Figure 4 The connection structure includes fastening holes 401 and fasteners 402 corresponding to the fastening holes 401. The fastening holes 401 are located around the first mounting hole 111 of the first base 110 and around the second mounting hole 121 of the second base 120. The fasteners 402 pass through the fastening holes 401 in the first base 110 and the fastening holes 401 in the second base 120, thereby connecting the first base 110 and the second base 120. Rivets are preferably used for the fasteners 402 to facilitate a stable connection between the bearing assemblies.

[0055] In a preferred embodiment, see Figure 5 and Figure 6 The connection structure includes a claw 140 and a slot 150. The claw 140 is made of steel. One of the first base body 110 and the second base body 120 is provided with the claw 140, and the other of the first base body 110 and the second base body 120 is provided with a slot 150. When the claw 140 passes through the slot 150, the user can use an external tool to deform the end of the claw 140 that passes through the slot 150 so that the claw 140 no longer separates from the slot 150, thereby achieving a stable connection between the first base body 110 and the second base body 120.

[0056] In this embodiment, the connection between the first base body 110 and the second base body 120 is achieved by providing the claws 140 and the slots 150 , eliminating the fasteners 402 , resulting in lower material costs and greater convenience for assembling the bearing assembly.

[0057] Specifically, see Figure 3 、 Figure 5 and Figure 7 The first base body 110 has an annular rib 160 extending from the edge of the first mounting hole 111 in a direction away from the second base body 120. Conversely, the second base body 120 has an annular rib 160 extending from the edge of the second mounting hole 121 in a direction away from the first base body 110. The annular ribs 160 on both sides can form a limit on both ends of the spherical bearing 200 in the axial direction, thereby limiting the spherical bearing 200 from axially extending along the first mounting hole 111 and the second mounting hole 121, improving the stability of the bearing assembly during operation, and facilitating the long-term stable operation of the photovoltaic bracket. The inner walls of the two annular ribs 160 are preferably spherical in structure, which can adapt to the outer wall of the spherical bearing 200 and achieve a better limiting effect.

[0058] In the above embodiments, the spherical bearing 200 can be of an integrated structure or a split structure. The split structure is more convenient for the user to adjust the spherical bearing 200 during installation to ensure the smoothness and synchronization of the rotation of the synchronization shaft 302.

[0059] Specifically, see Figure 4 and Figure 6 Taking the spherical bearing 200 with a split structure as an example, the spherical bearing 200 may specifically include a first split 210 and a second split 220. The first split 210 and the second split 220 are radially connected and jointly form a bearing hole 230 for the synchronous shaft 302 to pass through, so as to form an integral body that is adapted to the outer wall of the synchronous shaft 302 in the circumferential direction.

[0060] For example, see Figure 7 and Figure 8 One of the first split body 210 and the second split body 220 is provided with an insert block 240, and the other of the first split body 210 and the second split body 220 is provided with a slot 250, and the insert block 240 is inserted into the slot 250 to achieve a radial connection between the first split body 210 and the second split body 220.

[0061] In this embodiment, when the insert 240 is inserted into the slot 250, the slot 250 only restricts the axial movement of the insert 240; there is no radial restriction between the insert 240 and the slot 250. However, when the connected spherical bearing 200 is installed in the bearing seat 100, the wall of the mounting hole in the bearing seat 100 prevents the slot 250 and the insert 240 from separating from each other, ensuring a stable connection between the first and second sub-sections 210 and 220 and achieving high structural efficiency.

[0062] Specifically, the first split body 210 and the second split body 220 are both hemispherical in structure, and the first split body 210 is provided with the above-mentioned insert blocks 240 at both ends in the circumferential direction, and the second split body 220 is provided with the above-mentioned slots 250 at both ends in the circumferential direction. By inserting the insert blocks 240 into the slots 250, the first split body 210 and the second split body 220 form a complete spherical bearing 200, and then the spherical bearing 200 is installed in the bearing seat 100, the assembly of the bearing assembly can be completed, and a stable connection between the first split body 210 and the second split body 220 can be achieved.

[0063] Of course, in actual production, plug blocks 240 and slots 250 can be respectively set at both ends of the first split 210 in the circumferential direction, and corresponding slots 250 and plug blocks 240 can be set at corresponding positions of the second split 220. There is no limitation here, and all are within the scope of protection of this application.

[0064] For example, one of the first and second sub-bodies 210, 220 is provided with a buckle, and the other of the first and second sub-bodies 210, 220 is provided with a slot. When the buckle is engaged in the slot, a radial connection between the first and second sub-bodies 210, 220 is achieved. In this embodiment, the first and second sub-bodies 210, 220 are secured using a buckle connection. Because the buckle itself has a limited locking structure and is not easily disengaged from the slot, a stable connection between the first and second sub-bodies 210, 220 can be achieved without the aid of external structures, which is highly practical.

[0065] Specifically, both the first and second sub-bodies 210 and 220 are hemispherical in structure. The first sub-bodies 210 are provided with the aforementioned snaps at both ends of the circumference, while the second sub-bodies 220 are provided with the aforementioned slots at both ends of the circumference. By snapping the snaps into the slots, a stable connection is achieved between the first and second sub-bodies 210 and 220. At this point, the spherical bearing 200 is then installed in the bearing seat 100, completing the assembly of the bearing assembly.

[0066] In actual production, buckles and slots can be respectively provided at both ends of the first split 210 in the circumferential direction, and corresponding slots and buckles can be provided at corresponding positions of the second split 220. The specific structure between the buckles and the slots is not limited as long as they can achieve limited matching. They will not be elaborated here one by one, and they are all within the protection scope of this application.

[0067] Specifically, see Figure 7 and Figure 8 The spherical bearing 200 is also provided with a plurality of weight-reducing holes 260 to reduce the mass of the spherical bearing 200 , reduce material costs, and achieve lightweight production of the spherical bearing 200 .

[0068] The present application provides a photovoltaic bracket, comprising a column, a synchronous shaft 302, and a bearing assembly provided in any of the above embodiments, wherein the bearing assembly comprises a bearing seat 100 and a spherical bearing 200 disposed within the bearing seat 100. A plurality of columns are vertically arranged in sequence, and a column top seat 301 is provided at the top of each column for docking with the bearing seat 100, and a plurality of spherical bearings 200 are sequentially inserted through the synchronous shaft 302.

[0069] In addition, see Figure 1 The photovoltaic support further includes a drive mechanism, a main shaft, a main shaft bearing seat 303, a main shaft bearing 304, and purlins. The main shaft bearing seat 303 is fixed to the column top seat 301, and the main shaft bearing 304 is mounted on the main shaft bearing seat 100. The main shaft is sequentially interspersed with multiple main shaft bearings 304, and multiple purlins are sequentially mounted on the main shaft for mounting photovoltaic panels. Driven by the drive mechanism, the main shaft can rotate relative to the main shaft bearing seat 100 within the main shaft bearing 304, thereby driving the purlins and photovoltaic components to rotate synchronously. At the same time, driven by the drive mechanism, the synchronization shaft 302 rotates synchronously with the main shaft, transmitting the power of the drive mechanism to the driven drive point, thereby improving the power transmission efficiency of the drive mechanism.

[0070] In summary, the bearing assembly used to support the synchronous shaft uses a spherical bearing and a split bearing seat. The use of the spherical bearing not only provides upward support for the synchronous shaft, reducing deflection, but also effectively improves the synchronous shaft from getting stuck, allowing for smoother rotation and ensuring synchronization of power transmission between the main beam and the synchronous shaft. The use of a split bearing seat further improves processing and installation convenience.

[0071] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant description of other embodiments.

[0072] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of this application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered as the scope of protection of this application.
