Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and in particular to a bearing housing and a tracking bracket. Background Technology

[0002] In solar photovoltaic (PV) power generation systems, tracking brackets are key devices for improving the power generation efficiency of PV modules. Their core function is to control the PV modules to always face the sun by tracking the angle of sunlight in real time, thereby maximizing the absorption of solar radiation. This device typically uses photosensitive elements to sense the sun's position, and a control system drives related mechanisms to achieve automatic rotation of the PV modules.

[0003] Structurally, the tracking bracket mainly consists of a column, a drive mechanism (mostly a worm gear reducer with a self-locking function), a main beam, bearing housings, and polymer bearings. The photovoltaic modules are fixed to the main beam via purlins. Among these components, the bearing housings, as a key structure connecting the column and the main beam, must simultaneously meet both functional and structural strength requirements.

[0004] Currently, existing technologies for bearing housings on non-drive columns of tracking brackets generally employ complex casting processes. These castings require multiple complex steps, including melting, pouring, and cooling, which not only leads to high production costs but also significantly extends the processing cycle. Furthermore, when adjusting the north-south angle of photovoltaic modules, existing bearing housings have limited adjustment ranges, and the operation is cumbersome and inconvenient, making it difficult to flexibly adapt to the needs of different terrains or installation scenarios.

[0005] Given that the existing tracking bracket's cast bearing housing has problems such as high cost, long processing cycle, and inconvenience in north-south angle adjustment, there is an urgent need to design a bearing housing structure that is lower in cost, has a shorter processing cycle, is structurally safe and stable, and can easily achieve north-south angle adjustment, in order to solve the shortcomings of the existing technology. Utility Model Content

[0006] To address the aforementioned technical issues, this utility model provides a bearing housing and a tracking bracket. By adopting a split-type stamped bearing housing design, combined with an integrated spherical polymer photovoltaic bearing, the goal of reducing manufacturing costs and shortening the processing cycle is achieved. At the same time, the structural safety and stability are ensured, and the angle of the main beam can be easily adjusted, thereby improving the economy, installation flexibility, and operational adaptability of the tracking bracket and meeting the application needs of large-scale photovoltaic power plants.

[0007] To achieve the above objectives, this utility model provides a bearing housing, including a matching stamped cover plate and a stamped bearing base. The bottom of the stamped cover plate is stamped to form an ear plate, and the top of the stamped bearing base is formed with a connecting part that matches the ear plate. When the stamped cover plate and the stamped bearing housing are closed, they are connected to each other through the ear plate and the connecting part.

[0008] Furthermore, a photovoltaic bearing is installed within the accommodating space formed by the stamped cover plate and the stamped bearing base.

[0009] Furthermore, the photovoltaic bearing is an integrated spherical polymer bearing structure, the outer contour surface of the photovoltaic bearing is a spherical surface, and the inner wall structure of the accommodating space of the bearing seat is adapted to the spherical outer contour surface of the photovoltaic bearing, so that when the main beam drives the photovoltaic bearing to rotate relative to the bearing seat, the angle of the main beam can be adjusted.

[0010] Furthermore, the outer edges of the stamped cover plate and the stamped bearing base at both axial ends are stamped to form outwardly folded flanges.

[0011] Furthermore, the photovoltaic bearing is an integrated cylindrical polymer bearing structure, and the outer contour surface of the photovoltaic bearing is a cylindrical surface.

[0012] Furthermore, the outer edges of the stamped cover plate and the stamped bearing base at both axial ends are stamped to form outwardly folded flanges.

[0013] Furthermore, the stamped bearing base is composed of two identical stamped sub-parts.

[0014] This utility model also provides a tracking bracket, including a main beam, a non-driving column, and the bearing seat as described in the claims; the bottom of the stamped bearing seat is connected to the non-driving column; the photovoltaic bearing has an accommodating space inside that is adapted to the outer contour of the main beam;

[0015] The non-drive column is an I-beam, and the bottom of the stamped sub-part is connected to the outer wall of the two end flanges of the non-drive column through a bracket adapter or directly to the middle waist plate of the non-drive column.

[0016] Furthermore, the stamped sub-part is H-shaped in general, and the bottom ends of the stamped sub-part have folded edges. The folded edges of the two stamped sub-parts overlap and are fixedly connected to the top of the bracket adapter by bolts. The bracket adapter is bolted to the wing plate of the non-drive column.

[0017] Furthermore, the stamped sub-part is Y-shaped as a whole, with its bottom end attached to the middle waist plate of the non-drive column and fixed by bolts.

[0018] The beneficial effects of this utility model are:

[0019] 1. This utility model bearing housing adopts a combination structure of stamped cover plate and stamped bearing base. Compared with traditional complex castings, it eliminates cumbersome processes such as melting, pouring, and cooling, resulting in higher material utilization, reduced manufacturing costs, shorter processing cycles, and significantly improved production efficiency. Furthermore, it adopts a universal and modular design: the stamped bearing base is composed of two identical stamped sub-parts, requiring only one set of molds for mass production, thus reducing mold development costs. At the same time, the adaptable design of H-type and Y-type stamped sub-parts reduces the types of special components, further compressing procurement and inventory costs.

[0020] 2. The stamped cover plate and bearing base are precisely aligned and bolted together via ear plates and connecting parts, and overlapped with the bottom folded edge to ensure the overall structural rigidity. The stamped ribs can disperse stress and prevent local deformation, meeting the support requirements of large-span main beams. The flanged structure at both ends of the axial direction increases the torsional stiffness of the component while avoiding direct friction between the main beam and the bearing base edge during angle adjustment, reducing surface wear and extending the service life of the component.

[0021] 3. The integrated spherical polymer bearing, combined with the matching spherical structure on the inner wall of the bearing housing, enables convenient adjustment of the main beam and improves the tracking accuracy of the photovoltaic module for the solar altitude angle. Two connection schemes are provided to adapt to high load-bearing requirements and space-constrained scenarios, respectively. The Y-type scheme can also eliminate the need for bracket adapters, further simplifying the installation process and reducing costs. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0029] This utility model discloses a bearing housing.

[0030] Reference Figure 1 A bearing housing adopts a split stamping structure design, consisting of a matching stamping cover plate 21 and a stamping bearing base 22. The enclosed space formed by the two provides a precise installation position for the photovoltaic bearing 4, ensuring that the photovoltaic bearing 4 operates stably under stress.

[0031] The connection between the stamped cover plate 21 and the stamped bearing base 22 adopts a modular design. The bottom of the stamped cover plate 21 is integrally formed with an ear plate 211 through a stamping process, and the ear plate 211 has pre-set connection holes. Correspondingly, the top of the stamped bearing base 22 is integrally formed with a connecting part 221 that matches the structure of the ear plate 211, and the connecting part 221 also has matching holes. When the stamped cover plate 21 and the stamped bearing base 22 are assembled together, the ear plate 211 and the connecting part 221 are aligned and fastened together with bolts, which not only facilitates assembly but also ensures connection strength. The bottom of the stamped bearing base 22 is connected to the non-drive column 5.

[0032] The photovoltaic bearing 4 is an integrated spherical polymer bearing structure. The photovoltaic bearing 4 is sleeved on the outside of the main beam 1 and installed in the bearing seat 2. The contour of its internal cavity is precisely matched with the outer contour of the main beam 1. The outer contour surface of the photovoltaic bearing 4 is designed as a smooth spherical surface. The inner wall of the bearing seat 2 is also processed into a matching spherical arc surface so that the angle of the main beam 1 can be adjusted when the main beam 1 drives the photovoltaic bearing 4 to rotate relative to the bearing seat 2.

[0033] Both the stamped cover plate 21 and the stamped bearing base 22 have outwardly folded flanges 24 formed on their outer edges at both axial ends through a stamping process. This flange 24 structure improves the torsional stiffness of the component and creates physical clearance space at both axial ends of the bearing base 2. When the main beam 1 is angled relative to the bearing base 2 via the photovoltaic bearing 4, it effectively prevents surface wear caused by friction between the surface of the main beam 1 and the edge of the bearing base 2. Furthermore, the main surface of the stamped bearing base 22 has several transverse or longitudinal ribs formed by stamping. The distribution of these ribs is consistent with the direction of force, effectively dispersing stress and preventing localized deformation.

[0034] The stamped bearing base 22 adopts an innovative modular structure, which is composed of two identical stamped sub-parts 222 connected by riveting or bolting. This design only requires one set of stamping dies to achieve mass production, effectively reducing costs and shortening the processing cycle compared with traditional castings.

[0035] Reference Figure 2 In another embodiment, the photovoltaic bearing 4 is an integral cylindrical polymer bearing structure, and the outer contour surface of the photovoltaic bearing is a cylindrical surface. The outer edges of the stamped cover plate 21 and the stamped bearing base 22 at both axial ends are stamped to form outwardly folded flanges 25. The flanges 25 provide structural strength to the bearing base 2 and also serve as anti-disengagement and limiting functions for the photovoltaic bearing 4, ensuring the stability of the photovoltaic bearing 4.

[0036] This utility model also discloses a tracking bracket.

[0037] Reference Figures 3 to 5 A tracking bracket includes a main beam 1, a non-drive column 5, and a bearing seat 2; the bottom of the stamped bearing seat 22 is connected to the non-drive column 5; the photovoltaic bearing 4 has an internal accommodating space adapted to the outer contour of the main beam 1; the non-drive column 5 is made of I-beam, such as model I10-I16, and the connection design between the stamped sub-part 222 and the non-drive column 5 has two adaptation schemes: it is connected to the outer wall of the two end flanges 51 of the non-drive column 5 through the bracket adapter 3 or directly connected to the middle waist plate 52 of the non-drive column 5.

[0038] When the stamped sub-part 222 is H-shaped as a whole, its bottom ends are stamped to form horizontal flanges 23, and bolt holes are opened on the flanges 23. During assembly, the flanges 23 of the two stamped sub-parts 222 overlap each other and are fixed to the top of the bracket adapter 3 by bolts; the bracket adapter 3 is rigidly connected to the outer walls of the two end flanges 51 of the non-drive column 5 by high-strength bolts. This solution is suitable for scenarios with high load-bearing capacity requirements.

[0039] Reference Figure 5 When the stamping sub-part 222 is Y-shaped, its bottom end is designed as a planar structure that fits into the middle waist plate 52 of the non-drive column 5. It is directly fastened by bolts that pass through the waist plate 52. This solution has a more compact structure and is especially suitable for installation environments with limited space. Moreover, since there is no need for the bracket adapter 3, the cost of this solution is lower and the installation is convenient.

The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
