Abstract
Description
Technical Field
[0001] This application belongs to the field of photovoltaic support technology, and in particular relates to a limiting structure, a photovoltaic support, and a photovoltaic system. Background Technology
[0002] In related technologies, the driving of photovoltaic systems is usually multi-point mechanical linkage. When shipping, the manufacturer adjusts the main shaft connector of the rotary reducer to 0 degrees (i.e., the upper surface of the main shaft connector is parallel to the horizontal plane). However, the reduction ratio of the rotary reducer itself is all above 100:1. The small error of the rotary reducer will be transmitted to the error on the mounting hole of the drive shaft connector of the rotary reducer, which will increase sharply, making it difficult to match the drive shaft and the drive shaft connector.
[0003] However, in order to save time and effort during installation, workers may rotate the drive shaft significantly to match it with the drive shaft connector (in severe cases, even 90 degrees). As the angular deviation accumulates, it will cause the main shaft to twist severely, affecting the performance of the photovoltaic bracket. Utility Model Content
[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a limiting structure that can reduce the risk of severe torsion of the main shaft, improve the performance of the photovoltaic support, facilitate assembly and disassembly, and make it easy for workers to use.

[0006] According to the limiting structure of this application, by having the connector pass through the limiting hole and connect with the drive shaft connector, during installation, due to the limiting effect of the limiting hole, the connector can only rotate within a fixed range, thereby allowing the drive shaft to be adjusted only within a certain rotation angle.

[0032] The embodiments of this application 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 application, and should not be construed as limiting this application.
[0033] The following is for reference. Figure 1 and Figure 2 The present application describes a limiting structure 200, a photovoltaic bracket 100, and a photovoltaic system according to embodiments thereof.
[0034] like Figure 1 and Figure 2 As shown, the limiting structure 200 according to an embodiment of this application includes: a limiting body 10 and a connecting member 2. The limiting body 10 forms a limiting hole 121, and the connecting member 2 passes through the limiting hole 121 and is adapted to be connected to the drive shaft connecting member 61 of the reducer 300.
[0035] The limiting body 10 forms a limiting hole 121. As some embodiments of this application, the limiting hole 121 can be configured to be along the height direction of the limiting structure 200 (i.e., Figure 2 The through-hole structure (shown in the Z direction) penetrates the limiting body 10, and the limiting hole 121 can be formed at the upper end of the limiting body 10. It should be noted that the width of the limiting hole 121 is slightly larger than the cross-sectional width of the connector 2, so as to facilitate the movement of the connector 2 in the limiting hole 121.
[0036] As some embodiments of this application, the drive shaft connector 61 is provided with a connecting hole, which is adapted to the connector 2. The connector 2 passes through the limiting hole 121 and is adapted to connect with the drive shaft connector 61 of the reducer 300, specifically, along the height direction of the limiting structure 200 ( Figure 2 (As shown in the Z direction), the limiting hole 121 is located above the drive shaft connector 61, and the connector 2 passes through the limiting hole 121 and is assembled with the connecting hole of the drive shaft connector 61 to connect with the drive shaft connector 61.
[0037] As some embodiments of this application, the connector 2 can be configured as a pin, along the height direction of the limiting structure 200 ( Figure 2 (As shown in the Z direction), the limiting hole 121 is located above the drive shaft connector 61, and the pin passes through the limiting hole 121 and mates with the connecting hole of the drive shaft connector 61 to connect with the drive shaft connector 61. As some embodiments of this application, the connector 2 can be constructed as a bolt, along the height direction of the limiting structure 200 ( Figure 2 (As shown in the Z direction), the limiting hole 121 is located above the drive shaft connector 61, and the bolt passes through the limiting hole 121 and is threadedly engaged with the connecting hole of the drive shaft connector 61 to connect with the drive shaft connector 61.
[0038] It should be noted that during the installation of the photovoltaic bracket 100, in order to save time and effort, workers may rotate the drive shaft significantly to match it with the drive shaft connector 61 (in severe cases, even 90 degrees rotation is required). Furthermore, since the photovoltaic bracket 100 is relatively long, it is usually installed in sections. When workers adjust the drive shaft angle sequentially at each installation point, it may cause excessive angular deviation between the rotary reducer 300 and the photovoltaic bracket 100, leading to spindle torsion and significant damage. However, by applying the limiting structure 200 proposed in this application, the limiting hole 121 can limit the adjustment of the drive shaft to a certain rotation angle during the installation of the rotary reducer 300, thereby reducing the risk of excessive angular deviation between the rotary reducer 300 and the photovoltaic bracket 100, which could lead to spindle torsion and significant damage.
[0039] Therefore, by having the connector 2 pass through the limiting hole 121 and connect it to the drive shaft connector 61, during installation, due to the limiting effect of the limiting hole 121, the connector 2 can only rotate within a fixed range, thereby allowing the drive shaft to be adjusted only within a certain rotation angle. This reduces the risk of severe torsion of the main shaft caused by workers rotating the drive shaft significantly during installation, which is beneficial to improving the performance of the photovoltaic bracket 100. Furthermore, the limiting structure 100 proposed in this application is easy to assemble and disassemble, making it convenient for workers to use.
[0040] In some embodiments of this application, such as Figure 1and Figure 2 As shown, the limiting body 10 includes: a first limiting member 1 and a second limiting member 3. Along the first direction, the two ends of the first limiting member 1 are connected to the second limiting member 3. The second limiting member 3 is disposed on the base 7 of the reducer 300.
[0041] Among them, along the first direction (i.e. Figure 2 As shown in the X direction), both ends of the first limiting member 1 are connected to the second limiting member 3. As some embodiments of this application, along the first direction (i.e., Figure 2 (As shown in the X direction), both ends of the first limiting member 1 are connected to the corresponding second limiting member 3, and both ends of the first limiting member 1 and the corresponding second limiting member 3 form an angle, for example, both ends of the first limiting member 1 and the corresponding second limiting member 3 are arranged in an L-shape. The first limiting member 1 and the second limiting member 3 can be fixedly connected, for example, the connection method of the first limiting member 1 and the second limiting member 3 can be, but is not limited to, welding connection, snap-fit connection, etc., or the first limiting member 1 and the second limiting member 3 can be integrally formed.
[0042] The second limiting member 3 is disposed on the base 7 of the reducer 300. As some embodiments of this application, the second limiting member 3 can be configured to be positioned along the first direction (i.e., Figure 2 The plate-like structure extending in the X direction (as shown) allows the second limiting member 3 to overlap with a portion of the base 7 of the reducer 300. In some embodiments of this application, the second limiting member 3 can be stacked above the base 7 of the reducer 300, and in some embodiments of this application, the second limiting member 3 can be stacked below the base 7 of the reducer 300.
[0043] By setting the second limiting member 3, the second limiting member 3 can be matched with the base 7 for limiting. This can reduce the risk that the limiting structure 100 will fail to limit when the transmission shaft is rotated and the connecting member 2 interferes with the limiting hole 121, and the limiting structure 100 will rotate with the rotating shaft. This is beneficial to improving the reliability of the limiting structure 100.
[0044] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the limiting hole 121 can be constructed as an arc-shaped hole. By constructing the limiting hole 121 as an arc-shaped hole, the limiting hole 121 can be adapted to the rotation trajectory of the connector 2, and the connector 2 can have a large rotation space within the limiting hole 121. In turn, the transmission shaft connector 61 can rotate a large range, making it convenient for workers to install the transmission shaft.
[0045] In some embodiments of this application, such as Figure 2As shown, the first limiting member 1 includes a connecting plate 11 and a limiting plate 12. The limiting plate 12 forms a limiting hole 121. Both ends of the limiting plate 12 are connected to the connecting plate 11, and the connecting plate 11 is connected to the corresponding second limiting member 3.
[0046] The first limiting member 1 includes a connecting plate 11 and a limiting plate 12. As some embodiments of this application, the number of connecting plates 11 can be two, along the first direction (i.e., Figure 2 (As shown in the X direction), two connecting plates 11 are respectively placed at both ends of the limiting plate 12, and the two connecting plates 11 are respectively connected to both ends of the limiting plate 12. The connecting plates 11 and the limiting plate 12 can be fixedly connected. For example, the connection method between the connecting plates 11 and the limiting plate 12 can be, but is not limited to, welding connection, snap-fit connection, etc., or the connecting plates 11 and the limiting plate 12 can be integrally formed.
[0047] The connecting plates 11 at both ends of the limiting plate 12 are respectively connected to the second limiting members 3 at both ends of the first limiting member 1. That is, the connecting plates 11 are connected between the limiting plate 12 and the corresponding second limiting members 3. The connecting plates 11 and the second limiting members 3 can be fixedly connected. For example, the connection method between the connecting plates 11 and the second limiting members 3 can be, but is not limited to, welding connection, snap-fit connection, etc., or the connecting plates 11 and the corresponding second limiting members 3 can be integrally formed.
[0048] By connecting the two ends of the limiting plate 12 with connecting plates 11, the structure of the limiting structure 200 can be made reasonable and easy to manufacture. It can also make the connection between the first limiting member 1 and the second limiting member 3 more secure. Moreover, the two connecting plates 11 can be located at both ends of the transmission shaft connector 61, thereby providing a receiving space for the transmission shaft connector 61 and reducing the risk of interference between the limiting structure 200 and the transmission shaft connector 61 during disassembly and assembly.
[0049] In some embodiments of this application, such as Figure 2 As shown, the connecting plate 11 is along the second direction (i.e., the height direction of the limiting structure 200). Figure 2 The connecting plate 11 extends in the Z direction (as shown), and both ends of the connecting plate 11 are connected to the limiting plate 12 and the second limiting member 3, respectively.
[0050] Among them, the connecting plate 11 is along the second direction (i.e., the height direction of the limiting structure 200), Figure 2 Extending in the Z direction (as shown), as in some embodiments of this application, along the second direction (i.e., the height direction of the limiting structure 200), Figure 2 (As shown in the Z direction), the connecting plate 11 has two opposite ends, one end of which is connected to the end of the limiting plate 12 near the connecting plate 11, and the other end is connected to the end of the second limiting member 3 near the connecting plate 11.
[0051] This arrangement raises the limiting plate 12, allowing the limiting plate 12 and the connecting plate 11 to define a larger receiving space. This receiving space is used to accommodate the drive shaft connector 61, thereby reducing the risk of interference between the limiting structure 200 and the rotating shaft connector 2 during disassembly and assembly, and improving the ease of disassembly and assembly of the limiting structure 200.
[0052] In some embodiments of this application, such as Figure 2 As shown, the limiting plate 12 is constructed as a flat plate or an arc-shaped plate.
[0053] The limiting plate 12 is constructed as a flat plate or an arc-shaped plate. In some embodiments of this application, the limiting plate 12 is constructed as a flat plate, and a limiting hole 121 is formed on the limiting plate 12. When the limiting plate 12 is constructed as a flat plate, the limiting hole 121 is a rectangular hole. In some embodiments of this application, the limiting plate 12 is constructed as an arc-shaped plate, and the limiting hole 121 is formed on the limiting plate 12. When the limiting plate 12 is constructed as an arc-shaped plate, the limiting hole 121 is an arc-shaped hole. This configuration allows the limiting plate 12 to have multiple structural forms, thus providing better selectivity according to actual needs.
[0054] In some embodiments of this application, such as Figure 2 As shown, the limiting body 10 also includes: a third limiting member 4, along the first direction (i.e. Figure 2 As shown in the X direction), at least one end of the first limiting member 1 is connected to the third limiting member 4, along the second direction (i.e., the height direction of the limiting structure 200). Figure 2 (as shown in the Z direction), the third limiting member 4 and the corresponding second limiting member 3 are spaced apart to form a slot 5, which is suitable for receiving part of the structure of the base 7.
[0055] Among them, along the first direction (i.e. Figure 2 (as shown in the X direction), at least one end of the first limiting member 1 is connected to the third limiting member 4. For example, the third limiting member 4 is connected to the connecting plate 11 at at least one end of the first limiting member 1. As some embodiments of this application, along the first direction (i.e., Figure 2 As shown in the X direction), a third limiting member 4 is connected to the connecting plate 11 at one end of the first limiting member 1. As some embodiments of this application, along the first direction (i.e., Figure 2 (As shown in the X direction), a third limiting member 4 is connected to the connecting plates 11 at both ends of the first limiting member 1. The first limiting member 1 and the third limiting member 4 can be fixedly connected. For example, the connection method between the first limiting member 1 and the third limiting member 4 can be, but is not limited to, welding connection, snap-fit connection, etc., or the first limiting member 1 and the third limiting member 4 can be integrally formed.
[0056] Along the second direction (i.e., the height direction of the limiting structure 200), Figure 2As shown in the Z direction), the third limiting member 4 and the corresponding second limiting member 3 are spaced apart to form a slot 5. As some embodiments of this application, along the second direction (i.e., the height direction of the limiting structure 200), Figure 2 (as shown in the Z direction), the third limiting member 4 can be located above the corresponding second limiting member 3, and there is a gap between the third limiting member 4 and the corresponding second limiting member 3 to form a slot 5. As some embodiments of this application, along the second direction (i.e., the height direction of the limiting structure 200), Figure 2 (As shown in the Z direction), the third limiting member 4 can be located below the corresponding second limiting member 3, and there is a gap between the third limiting member 4 and the corresponding second limiting member 3 to form a slot 5. The slot 5 is suitable for receiving a part of the structure of the base 7, that is, a part of the structure of the base 7 can be received in the slot 5. It should be noted that the length of the gap between the third limiting member 4 and the corresponding second limiting member 3 is adapted to the thickness of the base plate so that the slot 5 can receive a part of the structure of the base 7.
[0057] By setting a third limiting member 4 spaced apart from the second limiting member 3 to form a slot 5, the slot 5 can be assembled with a part of the structure of the base 7, making it easy to install the limiting structure 200 on the base 7. Both the second limiting member 3 and the third limiting member 4 can be matched with the base 7 for limiting. This can effectively reduce the risk of the limiting structure 100 failing its limiting function when the transmission shaft rotates and the connecting member 2 interferes with the limiting hole 121, causing the limiting structure 100 to rotate with the rotating shaft. This is beneficial to improving the reliability of the limiting structure 100.
[0058] In some embodiments of this application, such as Figure 2 As shown, along the first direction (i.e. Figure 2 (in the X direction shown), both ends of the first limiting member 1 are connected to the third limiting member 4.
[0059] Among them, along the first direction (i.e. Figure 2 (As shown in the X direction), both ends of the first limiting member 1 are connected to the third limiting member 4. Specifically, the connecting plates 11 at both ends of the first limiting member 1 are connected to the third limiting member 4. The connecting plates 11 and the third limiting members 4 can be fixedly connected. For example, the connection method between the connecting plates 11 and the third limiting members 4 can be, but is not limited to, welding connection, snap-fit connection, etc., or the connecting plates 11 and the third limiting members 4 can be integrally formed.
[0060] This configuration allows both ends of the limiting structure 200 to have slots 5, which can more effectively reduce the risk of the limiting structure 100 failing to limit when the rotating drive shaft causes the connecting piece 2 to interfere with the limiting hole 121, and the limiting structure 100 rotates with the rotating shaft. It also makes the structures at both ends of the first limiting piece 1 consistent, which is convenient for production.
[0061] In some embodiments of this application, such as Figure 2 As shown, the second limiting member 3 and / or the third limiting member 4 are provided with mounting holes 31, which are adapted to be assembled with the base 7.
[0062] The second limiting member 3 has a mounting hole 31, or the third limiting member 4 has a mounting hole 31, or both the second limiting member 3 and the third limiting member have mounting holes 31, and the mounting holes 31 are suitable for assembling with the base 7.
[0063] As some embodiments of this application, the mounting hole 31 can be constructed as a threaded hole, and the number of mounting holes 31 can be multiple, for example, the number of mounting holes 31 can be, but is not limited to, one, two, three, etc. As some embodiments of this application, the base 7 has mating holes corresponding to the mounting holes 31, and bolts can be sequentially passed through the mating holes and the mounting holes 31 and threadedly engaged with the mounting holes 31 to fix the limiting structure 200 to the base 7.
[0064] As some embodiments of this application, the mounting hole 31 can be constructed as a through hole, and the number of mounting holes 31 can be multiple, for example, the number of mounting holes 31 can be, but is not limited to, one, two, three, etc. As some embodiments of this application, the base 7 has mating holes corresponding to the mounting holes 31, and bolts can be sequentially inserted into the mating holes and mounting holes 31 and engaged with nuts to fix the limiting structure 200 to the base 7. This arrangement can firmly install the limiting structure 200 on the base 7, reduce the risk of the limiting structure 200 falling off, and facilitate disassembly and assembly, which is beneficial to improving the ease of use of the limiting structure 200.
[0065] In some embodiments of this application, such as Figure 2 As shown, both the second limiting member 3 and the third limiting member 4 are constructed as flat plates;
[0066] And / or, the first limiting member 1, the second limiting member 3, and the third limiting member 4 are integrally formed.
[0067] The second limiting member 3 and the third limiting member 4 are both constructed as flat plates, or the first limiting member 1, the second limiting member 3, and the third limiting member 4 are integrally formed, or the second limiting member 3 and the third limiting member 4 are both constructed as flat plates, and the first limiting member 1, the second limiting member 3, and the third limiting member 4 are integrally formed.
[0068] The second limiting member 3 and the third limiting member 4 are both constructed as flat plates, which facilitates the formation of a slot 5 that matches the base plate, making it easier for the limiting structure 200 to cooperate with the base 7. At the same time, the flat plate structure can increase the contact area between the second limiting member 3, the third limiting member 4 and the base 7, thereby improving the stability of the limiting structure 200 and reducing the risk of rotation of the limiting structure 200.
[0069] The first limiting component 1, the second limiting component 3, and the third limiting component 4 are integrally formed. That is to say, the first limiting component 1, the second limiting component 3, and the third limiting component 4 are constructed as an integrally formed component. The integrally formed component has good structural strength. By making the first limiting component 1, the second limiting component 3, and the third limiting component 4 integrally formed, the connection reliability between the first limiting component 1 and the second limiting component 3 and the third limiting component 4 can be improved, the risk of breakage at the connection between the first limiting component 1 and the second limiting component 3 and the third limiting component 4 can be reduced, and it is also easy to manufacture.
[0070] As some embodiments of this application, the third limiting member 4 and the first limiting member 1 can be connected by an arc segment.
[0071] like Figure 1 As shown, the photovoltaic bracket 100 according to the embodiment of this application includes: a limiting structure 200 and a reducer 300. The limiting structure 200 is the limiting structure 200 of the above embodiment. The reducer 300 includes a reducer body 6. The reducer body 6 has a transmission shaft connector 61. The connector 2 passes through the limiting hole 121 and is connected to the transmission shaft connector 61.
[0072] The reducer 300 includes a reducer body 6, which has a drive shaft connector 61. In some embodiments of this application, the drive shaft connector 61 has a connecting hole that is adapted to a connector 2. The connector 2 passes through a limiting hole 121 and is connected to the drive shaft connector 61. Specifically, the connector 2 passes through the limiting hole 121 and is fitted with the connecting hole of the drive shaft connector 61 to connect to the drive shaft connector 61.
[0073] As some embodiments of this application, the reducer body 6 may include a base 7, and a second limiting member 3 is disposed on the base 7. The second limiting member 3 and part of the base 7 may be overlapped. As some embodiments of this application, the second limiting member 3 may be stacked on top of the base 7. As some embodiments of this application, the second limiting member 3 may be stacked on the bottom of the base 7.
[0074] Therefore, by having the connector 2 pass through the limiting hole 121 and connect it to the drive shaft connector 61, during installation, due to the limiting effect of the limiting hole 121, the connector 2 can only rotate within a fixed range, thereby allowing the drive shaft to be adjusted only within a certain rotation angle. This reduces the risk of severe torsion of the main shaft caused by workers rotating the drive shaft significantly during installation, which is beneficial to improving the performance of the photovoltaic bracket 100. Furthermore, the limiting structure 100 proposed in this application is easy to assemble and disassemble, making it convenient for workers to use.
[0075] The photovoltaic system according to the embodiments of this application includes the photovoltaic bracket 100 described above. By having the connector 2 pass through the limiting hole 121 and connect to the drive shaft connector 61, during installation, due to the limiting effect of the limiting hole 121, the connector 2 can only rotate within a fixed range, thereby allowing the drive shaft to be adjusted only within a certain rotation angle. This reduces the risk of severe torsion of the main shaft caused by workers rotating the drive shaft significantly during installation, which is beneficial to improving the performance of the photovoltaic bracket 100. Furthermore, the limiting structure 100 proposed in this application is easy to assemble and disassemble, making it convenient for workers to use.
