Description

Technical Field

[0001] This utility model relates to the field of bearing housing technology, and in particular to a spherical bearing housing for photovoltaic tracking frames that can be opened and closed. Background Technology

[0002] In the solar photovoltaic industry, photovoltaic tracking brackets, by adjusting the angle of photovoltaic modules in real time to maximize the reception of solar radiation, have become key equipment for improving power generation efficiency. The bearing housing, as the core connecting component between the tracking bracket's main shaft and the column, directly affects the bracket's stability, installation efficiency, and service life. Currently, common photovoltaic tracking bracket bearing housings on the market are mainly divided into two types: integrated and split. Integrated bearing housings need to be pre-fitted before main shaft assembly, requiring multiple people or hoisting equipment for installation. Especially in large ground-mounted power plants, the installation process of long main shafts is cumbersome, posing risks of working at heights and resulting in low installation efficiency. While split bearing housings avoid the need for complete disassembly and assembly of the main shaft, they often use a flat flange splicing structure. This structure has significant drawbacks: firstly, the bearings are prone to seizing during the connection, making it difficult for the main shaft to rotate and accelerating wear; secondly, the existing connection methods between the bearing housing and the support also have shortcomings. Therefore, developing a bearing housing that combines ease of installation, high-precision fit, and structural stability has become an urgent problem to be solved in the field of photovoltaic tracking brackets. Utility Model Content

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a spherical bearing seat for photovoltaic tracking frames that is easy to install, has high fitting precision, and stable structure, thus ensuring the stability of photovoltaic tracking frame operation.

[0004] This utility model provides a photovoltaic tracking frame opening and closing spherical bearing seat, including a support seat, which is integrally bent from a sheet metal; both sides of the sheet metal are bent upward at 90 degrees to form a support part, and an arc-shaped support groove is provided on the support part; both ends of the sheet metal are bent downward at more than 90 degrees to form a diagonal brace, and the bottom end of the diagonal brace is bent downward to form a vertical mounting part.

[0005] A semi-circular lower outer ring is welded to the support groove, and a semi-circular upper outer ring is separately disposed above the lower outer ring. The inner ring surfaces of the lower outer ring and the upper outer ring are located on the same spherical surface. The two ends of the upper outer ring are respectively detachably and lockably hinged to the support part through connecting components.

[0006] Furthermore, the support base is formed by bending a sheet metal piece with a thickness of 1.5-5mm.

[0007] Furthermore, both ends of the plate are bent downwards at 125-145 degrees to form diagonal bracing sections.

[0008] Furthermore, the mounting part is provided with several mounting holes.

[0009] Furthermore, the connecting assembly includes a connector, bolts, and a pin. The two ends of the upper outer ring are integrally provided with ear plates. The top end of the connector is fixedly connected to the ear plates by the bolts, and the bottom end is hinged to the support by the pin.

[0010] Furthermore, the connector is rectangular or U-shaped with the opening facing downwards.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) The bearing seat of this utility model adopts an open hinge design. The upper outer ring and the lower outer ring are detachably hinged through the connecting components. During installation, there is no need to disassemble the main shaft of the photovoltaic tracking frame. It can be operated by a single person. The installation time of the bearing seat is shortened by more than 60%. The installation is convenient and efficient, which significantly improves the construction efficiency of photovoltaic power stations and reduces labor costs and high-altitude operation risks.

[0013] (2) The upper outer ring and the lower outer ring adopt a spherical fit structure. By utilizing the self-aligning characteristics of the spherical surface, the coaxiality error during the main shaft installation process can be automatically compensated, effectively reducing the tracking error caused by shaking, improving the stability and reliability of the photovoltaic tracking frame operation, and improving the power generation efficiency of the photovoltaic module.

[0014] Its spherical fit and hinged design make it less demanding on the installation environment, highly adaptable and versatile, suitable for photovoltaic power station projects with complex terrain and limited construction conditions, and has broad application prospects.

[0015] (3) The lower outer ring is welded to the integrated bent support base, which has high structural rigidity, is sturdy and durable, and can effectively resist external loads such as strong winds and vibrations.

[0016] (4) The integrated bending and forming design of the support reduces the number of parts and processing steps, lowers the installation cost, and improves the economic benefits of photovoltaic projects.
