[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0030] The following is for reference. Figures 1-2 A photovoltaic tracking bracket 10 according to an embodiment of the present utility model is described.
[0031] like Figure 1 and Figure 2As shown, this application provides a photovoltaic tracking bracket 10, including: a bearing 1, which is used to be sleeved on the main shaft of the photovoltaic system 100, and the outer peripheral wall of the bearing 1 forms a limiting boss 11; a bearing seat 2, which is used to be fixed to the support column 20 of the photovoltaic system 100, the bearing seat 2 having a plurality of limiting rings 21, the plurality of limiting rings 21 being arranged sequentially along the axial direction of the bearing 1 and all sleeved on the bearing 1, at least two adjacent limiting rings 21 being spaced apart to form an assembly gap 22 between the corresponding two limiting rings 21, and at least one assembly gap 22 being fitted with the limiting boss 11.
[0032] The bearing 1 may have a mounting hole 14 through which the main shaft of the photovoltaic system 100 passes. Furthermore, the shape and dimensions of the mounting hole 14 are adapted to the shape and dimensions of the main shaft, which improves the relative stability of the bearing 1 and the main shaft when the bearing 1 is fitted onto the main shaft. The bearing 1 has a limiting boss 11 formed on its outer peripheral wall; that is, the limiting boss 11 is located on the surface of the bearing 1 opposite to the mounting hole 14.
[0033] The bearing housing 2 is fixed to the support column 20 of the photovoltaic system 100. For example, the bearing housing 2 and the support column 20 can be fixedly connected by means of bolts, hooks, etc. The bearing housing 2 has multiple limiting rings 21, for example, the bearing housing 2 has two, three or more limiting rings 21. Along the axial direction of the bearing 1, the multiple limiting rings 21 are arranged sequentially, and all the multiple limiting rings 21 are sleeved on the bearing 1 so that the bearing housing 2 can support the bearing 1 and work together to perform its function.
[0034] At least two adjacent limiting rings 21 are spaced apart to form an assembly gap 22 between the corresponding two limiting rings 21. At least one assembly gap 22 is fitted with a limiting boss 11. When the bearing 1 is subjected to force and tends to move axially, the limiting boss 11 abuts against the corresponding limiting ring 21 to limit the axial movement of the bearing 1, reducing the risk of the bearing 1 moving out of the limiting ring 21 or even slipping off the main shaft, effectively improving the stability of the bearing 1, and thus improving the reliability of the photovoltaic tracking bracket 10.
[0035] Specifically, the bearing 1 is fitted onto the main shaft of the photovoltaic system 100. The bearing housing 2 has two limiting rings 21, both of which are fitted onto the bearing 1. The bearing housing 2 and the support column 20 of the photovoltaic system 100 are fixedly assembled with bolts, achieving the effect of smoothly assembling the main shaft and the support column 20. A limiting boss 11 is formed on the outer peripheral wall of the bearing 1. The limiting boss 11 is assembled in the assembly gap 22 between the two limiting rings 21, and the limiting boss 11 and the two limiting rings 21 abut against each other for limitation.
[0036] Therefore, by setting a limiting boss 11, and fitting a limiting boss 11 on at least one assembly gap 22, the limiting boss 11 can abut against and limit the corresponding limiting ring 21, which helps to reduce the risk of axial movement of the bearing 1, thereby reducing the risk of the bearing 1 moving out of the limiting ring 21 or even slipping off the main shaft, effectively improving the stability of the bearing 1, and thus improving the reliability of the photovoltaic tracking bracket 10.
[0037] According to one embodiment of this application, such as Figure 1 As shown, the plurality of limiting rings 21 include a first limiting ring 211 and a second limiting ring 212. The first limiting ring 211 and the second limiting ring 212 are opposite to each other and spaced apart to form an assembly gap 22 between the first limiting ring 211 and the second limiting ring 212. At least a portion of the limiting boss 11 is located within the assembly gap 22.
[0038] The first limiting ring 211 and the second limiting ring 212 are arranged opposite to each other and spaced apart to form an assembly gap 22 between them. At least a portion of the limiting boss 11 is located within the assembly gap 22. In some embodiments of this application, a portion of the limiting boss 11 is located within the assembly gap 22. In some embodiments of this application, the entire structure of the limiting boss 11 is located within the assembly gap 22. When the bearing 1 is subjected to force and tends to move axially, the limiting boss 11 can abut against the first limiting ring 211 or the second limiting ring 212 to limit the axial movement of the bearing 1, thereby reducing the risk of the bearing 1 moving out of the limiting ring 21 or even slipping off the main shaft, effectively improving the stability of the bearing 1, and further improving the reliability of the photovoltaic tracking bracket 10.
[0039] According to one embodiment of this application, such as Figure 1 and Figure 2 As shown, multiple limiting bosses 11 are provided, and multiple limiting bosses 11 form a limiting boss group 12. The multiple limiting bosses 11 of the limiting boss group 12 are arranged along the axial direction of the bearing 1, and the two limiting bosses 11 located at the end of the limiting boss group 12 are respectively used to abut and limit the first limiting ring 211 and the second limiting ring 212.
[0040] The limiting boss 11 can be multiple, such as two, four, eight or more. Multiple limiting bosses 11 form a limiting boss group 12, which includes multiple limiting bosses 11, such as two, three or more. This application uses an example of eight limiting bosses 11 and a limiting boss group 12 including two limiting bosses 11. The two limiting bosses 11 of the limiting boss group 12 are arranged along the axial direction of the bearing 1, and the two limiting bosses 11 respectively abut against and limit the first limiting ring 211 and the second limiting ring 212. This arrangement restricts the bearing 1 from moving axially in any direction, further reducing the risk of the bearing 1 moving out of the limiting ring 21 or even slipping off the spindle.
[0041] According to one embodiment of this application, such as Figure 1 and Figure 2 As shown, there are multiple sets of limiting bosses 12, and each set of limiting bosses 12 includes multiple limiting bosses 11. The multiple sets of limiting bosses 12 are arranged sequentially along the circumference of the bearing 1.
[0042] The limiting boss group 12 consists of multiple groups, such as two, three, four or more groups. These multiple groups of limiting boss groups 12 are arranged sequentially along the circumference of the bearing 1. Each group of limiting boss groups 12 includes two, three, four or more limiting bosses 11. This arrangement ensures that the limiting boss groups 12 are evenly distributed on the outer circumferential wall of the bearing 1. When the bearing 1 is subjected to force and tends to move axially, the multiple limiting boss groups 12 are subjected to force along the circumference of the bearing 1, reducing the risk of stress concentration in any one group of limiting boss groups 12, which could lead to cracking or even breakage of the limiting bosses 11. This is beneficial to improving the reliability of axial limiting of the bearing 1.
[0043] According to one embodiment of this application, such as Figure 1 and Figure 2 As shown, the bearing 1 may include: a plurality of sub-bearings 13, which are arranged sequentially along the circumference of the bearing 1 to form the bearing 1, and each sub-bearing 13 has a limiting boss 11 formed on its outer peripheral wall.
[0044] There can be two, three or more sub-bearings 13. Multiple sub-bearings 13 are arranged in sequence along the circumference of bearing 1 to form bearing 1. Each sub-bearing 13 has a limiting boss 11 on its outer peripheral wall. This arrangement makes the design of the limiting boss 11 reasonable and helps to limit any sub-bearing 13 along the axial direction, reducing the risk of any sub-bearing 13 moving out of the limiting ring 21 or even slipping off the main shaft, thereby improving the working reliability of bearing 1.
[0045] According to one embodiment of this application, such as Figure 1 and Figure 2As shown, the bearing housing 2 also has multiple mounting parts 23, which are arranged sequentially along the axial direction of the bearing 1. Multiple limiting rings 21 and multiple mounting parts 23 are fixedly connected in a one-to-one correspondence. The mounting parts 23 are used to fix to the support column 20, and any two adjacent mounting parts 23 can be detachably connected.
[0046] The bearing housing 2 also has multiple mounting portions 23. For example, the bearing housing 2 has two, three, or more mounting portions 23 arranged sequentially along the axial direction of the bearing 1. The number of mounting portions 23 is consistent with the number of limiting rings 21, so that the multiple limiting rings 21 and the multiple mounting portions 23 correspond one-to-one. That is, one limiting ring 21 corresponds to one mounting portion 23, and the limiting ring 21 is fixedly connected to the corresponding mounting portion 23. The limiting ring 21 and the corresponding mounting portion 23 can be fixedly connected by, but not limited to, integral molding, welding, etc. The mounting portion 23 is used to fix to the support column 20. For example, the mounting portion 23 and the support column 20 can be fixedly assembled by, but not limited to, bolts, hooks, etc., so that the limiting ring 21 can be fixedly assembled to the support column 20 through the corresponding mounting portion 23, thereby achieving the effect of limiting the bearing 1.
[0047] Any two adjacent mounting parts 23 can be detachably connected. This arrangement makes the design of the mounting parts 23 more reasonable and facilitates the replacement of the bearing 1. Specifically, when the bearing 1 needs to be replaced after a period of use, any two adjacent mounting parts 23 are detached and moved along the axial direction of the bearing 1 in a direction away from each other. This causes the corresponding limiting ring 21 to move along the axial direction of the bearing 1 in a direction away from each other, at which point the limiting ring 21 releases its restriction on the bearing 1.
[0048] Multiple sub-bearings 13 are removed and replaced with new sub-bearings 13 arranged sequentially along the circumference of bearing 1 so that the new bearing 1 can be fitted onto the spindle. It is understood that by using multiple sub-bearings 13, the difficulty of disassembling and assembling bearing 1 can be reduced. After the new bearing 1 is fitted onto the spindle, adjacent mounting parts 23 are moved axially toward each other along the bearing 1, thereby causing the corresponding limiting rings 21 to move axially toward each other along the bearing 1. At this point, the limiting rings 21 reposition the new bearing 1, and the replacement of bearing 1 is complete.
[0049] By allowing any two adjacent mounting parts 23 to be detachably connected, the structure is simple and highly reliable, making the installation process of the photovoltaic tracking bracket 10 simple and quick, greatly improving the production efficiency of the photovoltaic tracking bracket 10. It also solves the problem of the difficulty in disassembling the bearing 1, making the maintenance and replacement of the bearing 1 easier, thereby reducing the maintenance cost of the photovoltaic tracking bracket 10.
[0050] According to one embodiment of this application, such as Figure 1 and Figure 2As shown, the photovoltaic tracking bracket 10 may further include: an assembly structure 3, which includes a first assembly structure 31 and a second assembly structure 32. One of the two adjacent mounting parts 23 is fixedly provided with one of the first assembly structure 31 and the second assembly structure 32, and the other of the two adjacent mounting parts 23 is fixedly provided with the other of the first assembly structure 31 and the second assembly structure 32. The first assembly structure 31 and the second assembly structure 32 are fixedly assembled by fasteners so that any two adjacent mounting parts 23 can be detachably connected.
[0051] In some embodiments of this application, one of the first assembly structure 31 and the second assembly structure 32 can be constructed as a groove structure, and the other of the first assembly structure 31 and the second assembly structure 32 can be constructed as a boss structure. In some embodiments of this application, both the first assembly structure 31 and the second assembly structure 32 can be constructed as assembly plates. One of two adjacent mounting portions 23 is fixedly fitted with one of the first assembly structure 31 and the second assembly structure 32, and the other of the two adjacent mounting portions 23 is fixedly fitted with the other of the first assembly structure 31 and the second assembly structure 32. The first assembly structure 31 and the second assembly structure 32 are fixedly assembled by fasteners, which can be, but are not limited to, bolts, pins, etc.
[0052] like Figure 2 As shown, the first assembly structure 31 has a first through hole 311, and the second assembly structure 32 has a second through hole 321. When the first assembly structure 31 and the second assembly structure 32 are fixedly assembled, fasteners can be simultaneously inserted through the first through hole 311 and the second through hole 321 to fix the first assembly structure 31 and the second assembly structure 32, thereby improving the stability of the bearing housing 2. When the bearing 1 needs to be replaced, the first assembly structure 31 and the second assembly structure 32 need to be disassembled, and the fasteners can be removed from the first through hole 311 and the second through hole 321, allowing the first assembly structure 31 and the second assembly structure 32 to be disassembled. By making any two adjacent mounting parts 23 detachably connected, it is easier to maintain and replace the bearing 1, thereby further reducing the maintenance cost of the photovoltaic tracking bracket 10.
[0053] According to one embodiment of this application, such as Figure 1 and Figure 2 As shown, there are multiple assembly structures 3, and the structures of multiple assembly structures 3 are the same.
[0054] Among them, there are two, four or more assembly structures 3, and the structures of multiple assembly structures 3 are the same. This setting can make the structure of assembly structure 3 reasonable, which helps to reduce the number of molds in the production process of photovoltaic tracking bracket 10, thereby reducing the production cost of photovoltaic tracking bracket 10. Furthermore, by making the structure design of multiple assembly structures 3 the same, the risk of reverse installation or incorrect installation in the assembly process of photovoltaic tracking bracket 10 can be reduced, the assembly difficulty of photovoltaic tracking bracket 10 can be reduced, and the assembly efficiency of photovoltaic tracking bracket 10 can be improved.
[0055] According to one embodiment of this application, such as Figure 1 and Figure 2 As shown, each mounting part 23 includes two sub-mounting parts 231, which are located on opposite sides of the corresponding limiting ring 21, and both sub-mounting parts 231 are fixedly connected to the corresponding limiting ring 21.
[0056] The two sub-mounting parts 231 are located on opposite sides of the corresponding limiting ring 21. It can be understood that the arrangement direction of the two sub-mounting parts 231 intersects both the circumferential direction of the bearing 1 and the extension direction of the support column 20. Both sub-mounting parts 231 are fixedly connected to the corresponding limiting ring 21. For example, the two sub-mounting parts 231 can be fixedly connected to the corresponding limiting ring 21 by, but not limited to, integral molding, welding, etc., reducing the risk of separation between the sub-mounting parts 231 and the corresponding limiting ring 21, thereby improving the stability and reliability of the photovoltaic tracking bracket 10.
[0057] According to one embodiment of this application, such as Figure 1 and Figure 2 As shown, the sub-mounting part 231 may include a connecting part 232 and a fixing part 233 that are fixedly connected. The connecting part 232 is located above the fixing part 233 and is fixedly connected to the corresponding limiting ring 21. The fixing part 233 includes a first plate 2331 and a second plate 2332. The first plate 2331 is connected between the second plate 2332 and the connecting part 232. The second plate 2332 and the first plate 2331 are bent and connected and used to fix to the support column 20.
[0058] The connecting part 232 and the fixing part 233 can be fixedly connected by, but not limited to, integral molding, welding, etc. The connecting part 232 is located above the fixing part 233 and is fixedly connected to the corresponding limiting ring 21, so that the fixing part 233 and the limiting ring 21 are connected through the connecting part 232. The fixing part 233 includes a first plate 2331 and a second plate 2332. The first plate 2331 is connected between the second plate 2332 and the connecting part 232. The second plate 2332 and the first plate 2331 are bent and connected, and the second plate 2332 is fixed to the support column 20. For example, the second plate 2332 and the support column 20 can be fixedly connected by, but not limited to, bolts, screws, etc. Specifically, such as Figure 2 As shown, the second plate 2332 can have a third through hole 2333. Bolts are inserted through the third through hole 2333 and the support column 20, and screwed onto the corresponding nuts, achieving a fixed connection between the second plate 2332 and the support column 20. By making the fixing part 233 include a first plate 2331 and a second plate 2332, and bending the second plate 2332 and the first plate 2331 together, after the photovoltaic tracking bracket 10 is assembled, a certain height difference can be created between the main shaft and the support column 20, reducing the risk of interference between the main shaft and the support column 20, thus facilitating the smooth assembly of the photovoltaic tracking bracket 10.
[0059] According to one embodiment of this application, such as Figure 1 and Figure 2 As shown, there are two first plates 2331, which are opposite to each other and spaced apart, and both first plates 2331 are connected between the second plate 2332 and the connecting part 232.
[0060] The two first plates 2331 are arranged opposite each other and spaced apart. Both first plates 2331 are connected between the second plate 2332 and the connecting part 232. This arrangement makes the structure of the fixing part 233 reasonable. When the second plate 2332 is fixedly assembled with the support column 20, the two first plates 2331 can avoid the assembly position. By fixing the second plate 2332 with the support column 20 through the space between the two first plates 2331, the assembly difficulty of the second plate 2332 and the support column 20 can be reduced, thereby improving the assembly efficiency of the photovoltaic tracking bracket 10.
[0061] like Figure 1 As shown, this application provides a photovoltaic system 100, including the photovoltaic tracking bracket 10 of the above embodiment.
[0062] In some embodiments of this application, the photovoltaic system 100 also includes a bearing seat support 30. The bearing seat 2 can be fixed to the support column 20 via the bearing seat support 30. The bearing seat support 30 and the support column 20 can be fixedly connected by, but not limited to, bolts, rivets, etc. The second plate 2332 is connected to the bearing seat support 30 by bolts, so that the bearing seat 2 is fixed to the support via the bearing seat support 30. When the bearing 1 needs to be replaced, all the second plates 2332 are removed from the bearing seat support 30, and the fasteners are removed, so that the first assembly structure 31 and the second assembly structure 32 move along the axial direction of the bearing 1 in a direction away from each other, causing the first limiting ring 211 and the second limiting ring 212 to separate, thereby removing the limiting of the bearing 1.
[0063] Multiple sub-bearings 13 are removed and replaced with new sub-bearings 13 arranged sequentially along the circumference of bearing 1 so that the new bearing 1 can be fitted onto the spindle. It is understood that by using multiple sub-bearings 13, the difficulty of disassembling and assembling bearing 1 can be reduced. After the new bearing 1 is fitted onto the spindle, adjacent mounting parts 23 are moved axially toward each other along the bearing 1, thereby causing the corresponding limiting rings 21 to move axially toward each other along the bearing 1. At this point, the limiting rings 21 reposition the new bearing 1, and the replacement of bearing 1 is complete.
[0064] The photovoltaic tracking bracket 10 has a simple structure, high reliability, and a simple and quick installation process, greatly improving the production efficiency of the photovoltaic tracking bracket 10. It also solves the problem of the difficulty in disassembling the bearing 1, facilitating the maintenance and replacement of the bearing 1, thereby reducing the maintenance cost of the photovoltaic tracking bracket 10. By setting a limiting boss 11, and fitting the limiting boss 11 into at least one assembly gap 22, the limiting boss 11 can abut and limit the corresponding limiting ring 21, which helps reduce the risk of axial movement of the bearing 1, thereby reducing the risk of the bearing 1 moving out of the limiting ring 21 or even slipping off the main shaft, effectively improving the stability of the bearing 1, and thus improving the reliability of the photovoltaic tracking bracket 10.
