Technical Field

[0001] The utility model relates to a bearing seat for a photovoltaic tracking system, belonging to the technical field of photovoltaic brackets. Background Art

[0002] A photovoltaic tracking system is a photovoltaic system that can automatically track the sun and improve the overall power generation. It mainly consists of a tracking bracket and photovoltaic modules. By tracking the movement of the sun in real time, the sunlight directly irradiates the photovoltaic array, thereby increasing the solar radiation received by the photovoltaic array and improving the overall power generation of the solar photovoltaic power generation system.

[0003] As an important part of the tracking bracket, the bearing seat is mainly used to install photovoltaic bearings. Most of the existing bearing seats are of a ring-shaped integral structure, which has the problems of difficult disassembly and assembly of bearings, time-consuming and laborious. After long-term use and bearing wear, it is easy to cause the bearing to fall off.

[0004] To solve the above problems, a bearing seat for a photovoltaic tracking system is proposed in this application. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a bearing seat for a photovoltaic tracking system. By designing the bearing seat into an upper and lower combined connection structure and cooperating with a quick connection mechanism with a self-locking function, the quick disassembly and assembly of photovoltaic bearings can be realized, which is convenient for installation and replacement, and can effectively solve the problems in the background art.

[0006] To solve the above technical problems, the utility model provides the following technical solutions:

[0007] A bearing seat for a photovoltaic tracking system includes an upper half seat and a lower half seat that are combined and connected to form an annular structure. One end of the upper half seat and the lower half seat is movably connected by a hinge, and the other end of the upper half seat and the lower half seat is locked by a quick connection mechanism. The quick connection mechanism consists of a pressing block, a spring, and a first wedge block. The pressing block is rotatably connected to the lower half seat, the first wedge block is fixedly connected to the upper half seat, and a second wedge block is fixedly connected to the pressing block. The second wedge block is pressed against the first wedge block by the action of the spring to lock the upper half seat and the lower half seat. By connecting the upper half seat and the lower half seat through a hinge and a quick connection mechanism, the quick installation of the bearing seat on the photovoltaic bearing is realized.

[0008] As a further improvement of the utility model, a first ear plate is fixedly connected to the lower half seat, and a second ear plate is fixedly connected to the same side of the pressing block and the second wedge block.

[0009] As a further improvement of the utility model, the first ear plate and the second ear plate are rotatably connected by a rotating shaft.

[0010] As a further improvement of the present utility model, a first convex block is provided below the second ear plate, and the first convex block is fixedly connected to the pressing block and extends into the spring.

[0011] As a further improvement of the present utility model, the spring is arranged between the lower half seat and the bottom of the pressing block.

[0012] As a further improvement of the present utility model, a protective cover is further provided on the top of the first wedge block, and the protective cover is fixedly connected to the upper half seat.

[0013] As a further improvement of the present utility model, the upper edges of the upper half seat and the lower half seat extend inward to form a baffle.

[0014] As a further improvement of the present utility model, the other end of the baffle bulges outward to form a retaining edge. The baffle and the retaining edge can further limit the photovoltaic bearing, preventing the photovoltaic bearing from falling off the bearing seat after wear.

[0015] The beneficial effects of the present utility model: A bearing seat for a photovoltaic tracking system, by designing the bearing seat as an upper and lower combined connection structure and cooperating with a quick-connection mechanism with a self-locking function, can realize the quick disassembly and assembly of the photovoltaic bearing, which is convenient for installation and replacement. By providing a baffle and a retaining edge on the upper half seat and the lower half seat, it can play a blocking role from the side after the photovoltaic bearing is severely worn after long-term use, preventing the photovoltaic bearing from falling off and affecting the stability of the overall photovoltaic system.

[0027] Embodiment

[0028] As Figure 7 shown, the bearing seat is used to install the photovoltaic bearing 18. The bearing seat is integrally fixedly connected to the top of the column 20. The photovoltaic bearing 18 is sleeved on the bearing seat, and the photovoltaic main beam 19 passes through the photovoltaic bearing 18.

[0029] As Figures 1 - 6As shown in the figure, a bearing seat for a photovoltaic tracking system includes an upper half seat 1 and a lower half seat 2 that are combined and connected to form an annular structure. One end of the upper half seat 1 and the lower half seat 2 is movably connected by a hinge 3, and the other end of the upper half seat 1 and the lower half seat 2 is locked by a quick connection mechanism 4. The quick connection mechanism 4 is composed of a pressing block 9, a spring 15, and a first wedge block 10. The pressing block 9 is rotatably connected to the lower half seat 2, the first wedge block 10 is fixedly connected to the upper half seat 1, and a second wedge block 11 is fixedly connected to the pressing block 9. The second wedge block 11 is pressed against the first wedge block 10 by the action of the spring 15 to lock the upper half seat 1 and the lower half seat 2.

[0030] In some alternative embodiments, a first ear plate 13 is fixedly connected to the lower half seat 2. A second ear plate 12 is fixedly connected to the same side of the pressing block 9 and the second wedge block 11. The first ear plate 13 and the second ear plate 12 are rotatably connected by a rotating shaft 14.

[0031] In some alternative embodiments, a first raised block 16 is provided below the second ear plate 12. The first raised block 16 is fixedly connected to the pressing block 9 and extends into the spring 15. The spring 15 is arranged between the bottom of the lower half seat 2 and the pressing block 9. Optionally, as Figure 3 shown, a groove is formed on the outer wall of the lower half seat 2, and a second raised block 16 is fixedly connected to the groove. The other end of the spring 15 extends into the groove and is sleeved on the second raised block 16. Or, the end of the spring 15 away from the pressing block 9 is directly fixedly connected to the lower half seat 2.

[0032] After the spring 15 is installed, it is in a compressed state, thus generating a force on the pressing block 9 in a direction away from the lower half seat 2. After the upper half seat 1 and the lower half seat 2 are installed by the quick connection mechanism 4, the first wedge block 10 and the second wedge block 11 are locked by the action of the spring 15 to achieve self-locking. When it is necessary to open the bearing seat, only need to press the pressing block 9 to compress the spring 15. At this time, the first wedge block 10 and the second wedge block 11 are separated, and then the upper half seat 1 can be rotated to replace the photovoltaic bearing 18.

[0033] In some alternative embodiments, a protective cover 8 is further provided on the top of the first wedge block 10. The protective cover 8 is fixedly connected to the upper half seat 1. The protective cover 8 plays a role in protecting the first wedge block 10 and the second wedge block 11.

[0034] Since most current photovoltaic bearings 18 are made of UPE (ultra-high molecular weight polyethylene) material, although they have good lubrication performance, their wear resistance is insufficient. After long-term use, the positions of the photovoltaic bearings 18 made of UPE material in contact with the photovoltaic main beam 19 and the bearing seat are severely worn. On the one hand, the photovoltaic bearings 18 need to be replaced after long-term use. On the other hand, after long-term wear, it is easy for the photovoltaic bearings 18 to fall off from the bearing seat, causing instability of the photovoltaic system.

[0035] In some alternative embodiments, on the upper half seat 1 and the upper edge position of the lower half seat 2, a baffle 5 extends inward, and the other end of the baffle 5 protrudes outward to form a retaining edge 6, which can play a role of limiting and blocking the photovoltaic bearing 18 from the side, preventing the photovoltaic bearing 18 from falling off from the bearing seat after long-term wear, and avoiding instability of the photovoltaic system.

[0036] During use, first install the lower half seat 2 on the top of the column 20 through the connecting seat 7, install the photovoltaic bearing 18 on the lower half seat 2, pass the photovoltaic main beam 19 through the photovoltaic bearing 18, and then rotate the upper half seat 1 and press the pressing block 9 to install the pressing block 9 on the top of the first wedge block 10, completing the quick installation of the bearing seat and the limitation of the photovoltaic bearing 18. When the photovoltaic bearing 18 needs to be replaced after long-term use, only need to press the pressing block 9 to compress the spring 15. At this time, the first wedge block 10 and the second wedge block 11 are separated, and then the upper half seat 1 can be rotated to replace the photovoltaic bearing 18.

[0037] The above is the preferred embodiment of the present invention. The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
