Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic support technology, specifically relating to a slewing bearing for photovoltaic supports. Background Technology

[0002] In photovoltaic (PV) power generation systems, PV mounting brackets are key structural components supporting PV modules. They not only need to ensure that PV modules receive sunlight at appropriate angles and directions to improve power generation efficiency, but also need to maintain structural stability and reliability under various complex environmental conditions, such as strong winds, heavy rain, and blizzards, to guarantee the safe operation of PV modules and extend their service life. Slewing bearings, as large bearings capable of withstanding comprehensive loads, play a crucial role in PV mounting brackets. They connect the fixed and rotatable parts of the PV mounting bracket, allowing the bracket to flexibly adjust according to the position and angle of the sun, thereby maximizing solar energy capture and improving the overall power generation efficiency of the PV power generation system. For example, the existing patent with publication number CN220869906U discloses "a slewing bearing for a photovoltaic mounting bracket, comprising a bearing housing, an outer bearing ring, and an inner bearing ring; the bearing housing is set on a mounting foundation; the outer bearing ring is set inside the bearing housing, and the inner surface of the outer bearing ring is spherical; the outer surface of the inner bearing ring is spherical, and the inner and outer bearing rings are connected by a spherical fit."

[0003] However, in the traditional design of slewing bearings for photovoltaic brackets, the connection between the slewing bearing and the photovoltaic bracket beam is usually achieved by combining multiple bolts. Each bolt requires precise positioning, installation, and tightening, resulting in low initial assembly efficiency. Furthermore, when the photovoltaic bracket needs to be inspected and maintained, and the slewing bearing needs to be separated from the photovoltaic bracket beam, disassembling a large number of bolts requires a lot of time and effort, reducing the convenience of subsequent disassembly and maintenance. Therefore, this utility model proposes a slewing bearing for photovoltaic brackets. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 5This is an embodiment of the present utility model, which provides a technical solution: a slewing bearing for a photovoltaic bracket, including a bearing housing 1, a bearing outer ring 2 installed inside the bearing housing 1, and a bearing inner ring 3 rotatably installed inside the bearing outer ring 2, and the photovoltaic bracket beam 4 passes through the inside of the bearing inner ring 3. The above structures are all prior art. For specific structures, please refer to the prior art patent with publication number CN220869906U, which will not be elaborated here.

[0025] Also includes

[0026] The plug-in connection structure between the inner ring 3 of the bearing and the photovoltaic support beam 4 includes two arc-shaped fixing seats 51 symmetrically welded and fixed to the surface of the inner ring 3 of the bearing, an arc-shaped mounting plate 52 installed on the outer surface of the arc-shaped fixing seat 51, a plug-in block 54 welded and fixed to the inner surface of the arc-shaped mounting plate 52, and a plug-in hole 55 opened on the surface of the photovoltaic support beam 4 for the plug-in block 54 to be inserted. The plug-in block 54 passes through the arc-shaped fixing seat 51 and is inserted into the plug-in hole 55, which can plug the arc-shaped fixing seat 51 and the photovoltaic support beam 4 together, thereby realizing the quick plug-in connection between the photovoltaic support beam 4 and the inner ring 3 of the bearing, so that the photovoltaic support beam 4 can rotate together with the inner ring 3 of the bearing. If the two need to be separated later, simply pull the arc-shaped mounting plate 52 to the side, so that the plug-in block 54 is pulled out, and the separation between the photovoltaic support beam 4 and the inner ring 3 of the bearing can be completed quickly, which solves the problem of inconvenient disassembly and assembly of the original slewing bearing.

[0027] The plug-in connection structure also includes a limiting structure 53 set between the arc-shaped mounting plate 52 and the arc-shaped fixing seat 51 to ensure the installation stability of the arc-shaped mounting plate 52 on the outer side of the arc-shaped fixing seat 51 during daily use, thereby ensuring that the plug-in block 54 is stably inserted into the plug-in hole 55 and ensuring the plug-in stability of the photovoltaic bracket beam 4 and the bearing inner ring 3.

[0028] In this embodiment, preferably, the limiting structure 53 includes two L-shaped operating plates 531 movably mounted on the two end surfaces of the arc-shaped mounting plate 52. The inner sides of the two L-shaped operating plates 531 are welded and fixed with limiting arc-shaped locking blocks 532, and the two end surfaces of the arc-shaped fixing seat 51 are provided with limiting arc-shaped locking grooves 533 corresponding to the limiting arc-shaped locking blocks 532. The end of the limiting arc-shaped locking block 532 is inserted into the limiting arc-shaped locking groove 533, so that the arc-shaped mounting plate 52 can be stably limited by the limiting arc-shaped locking blocks 532 during daily use, ensuring the installation stability of the arc-shaped mounting plate 52 on the outside of the arc-shaped fixing seat 51.

[0029] In this embodiment, preferably, the limiting structure 53 further includes two arc-shaped inner sliding grooves 534 formed inside both ends of the arc-shaped mounting plate 52. Arc-shaped inner sliders 535 are slidably mounted within the arc-shaped inner sliding grooves 534. An arc-shaped connecting block 537 is fixed to one side of the arc-shaped inner slider 535. Arc-shaped sliding grooves 539 are formed on both ends of the arc-shaped mounting plate 52 for the arc-shaped connecting block 537 to pass through and slide. The end of the arc-shaped connecting block 537 passes through the arc-shaped sliding groove 539 to the outside of the arc-shaped mounting plate 52 and is fixed to the L-shaped operating plate 531, allowing the L-shaped operating plate 531 to slide smoothly at the end of the arc-shaped mounting plate 52. A spring 536 is also installed inside the arc-shaped inner sliding groove 534 on the other side relative to the arc-shaped inner slider 535. Under the pushing action, the end of the limiting arc-shaped locking block 532 can be stably inserted into the limiting arc-shaped locking groove 533 during daily use, preventing it from slipping out and ensuring the limiting stability of the L-shaped operating plate 531 and the arc-shaped mounting plate 52. If it is necessary to release the limiting of the arc-shaped mounting plate 52 to realize the insertion and removal action of the plug-in block 54, the operator only needs to push the L-shaped operating plate 531, so that the arc-shaped connecting block 537, along with the arc-shaped inner slider 535, slides in the arc-shaped inner sliding groove 534, and gradually compresses the spring 536 until the end of the limiting arc-shaped locking block 532 moves out of the limiting arc-shaped locking groove 533, thus quickly releasing the limiting of the arc-shaped mounting plate 52. At this time, the arc-shaped mounting plate 52 can be moved to the side to realize the insertion and removal of the plug-in block 54, which is highly convenient to operate.

[0030] In this embodiment, preferably, one end of the spring 536 abuts against the surface of the arc-shaped inner slider 535, and the other end of the spring 536 abuts against the inner wall of the arc-shaped inner groove 534.

[0031] In this embodiment, preferably, an arc-shaped guide rod 538 is also fixed inside the arc-shaped inner groove 534, and the arc-shaped inner slider 535 is slidably sleeved on the surface of the arc-shaped guide rod 538. The arc-shaped guide rod 538 passes through the center of the inner side of the spring 536, which can guide and limit the spring 536 to prevent the spring 536 from deviating. The arc-shaped structure design of the arc-shaped inner slider 535, the arc-shaped inner groove 534, and the arc-shaped guide rod 538 makes the arc-shaped inner slider 535 stable within the arc. The L-shaped operating plate 531 slides smoothly within the groove 534. It is worth noting that the arc-shaped surfaces of the arc-shaped fixing seat 51, the arc-shaped mounting plate 52, the limiting arc-shaped locking block 532, and the limiting arc-shaped locking groove 533 are all centered on the axis of the photovoltaic support beam 4. This allows the L-shaped operating plate 531 to slide smoothly on the surface of the arc-shaped mounting plate 52, and also allows the limiting arc-shaped locking block 532 to smoothly insert into or slide out of the limiting arc-shaped locking groove 533 as the L-shaped operating plate 531 slides.

[0032] In this embodiment, preferably, the surface of the arc-shaped fixing base 51 is provided with a transverse through hole for the insertion block 54 to pass through.

[0033] In this embodiment, preferably, two strip-shaped guide grooves 31 are symmetrically opened on the inner wall of the inner ring 3 of the bearing, and two strip-shaped guide blocks 41 adapted to the strip-shaped guide grooves 31 are symmetrically fixed on the surface of the photovoltaic support beam 4, and the strip-shaped guide blocks 41 slide into the strip-shaped guide grooves 31.

[0034] In this embodiment, preferably, the bottom of the bearing housing 1 is provided with an integrated fixed base.

[0035] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
