Description

[0003] With the application of photovoltaics, various drawbacks have become increasingly apparent, such as the lack of installation sites. To address this issue and the lack of ability to cope with severe weather, the applicant designed a photovoltaic device and filed a Chinese patent application (application number CN2024213321033). This patent application discloses a support structure and a photovoltaic tracking system, including a power assembly and a accumulator. In this application, to fix the power assembly and accumulator in the photovoltaic device, the accumulator in the photovoltaic tracking system is fixedly connected to the support structure by a first fixing member, and the power assembly in the photovoltaic tracking system is fixedly connected to the support structure by a second fixing member.

The accumulator 400 can provide auxiliary force for the power assembly 300 to drive the photovoltaic module 500 to move. The detailed functions and structures of the accumulator 400 have been described in detail in the Chinese patent applications (such as application number: CN202420340371.3; CN202410203081.9) previously filed by the applicant, and will not be described again here.

The third connecting part 16 is a plane, a curved surface or a through hole on the bracket main body 11, and the bracket 1 and the support 2 are welded through the third connecting part 16. Figures 1 to 6

[0072] In summary, the bracket 1 has the following two implementation manners:

[0073] As shown in the figure, the bracket 1 has the following two implementation manners: Figure 2 ​​As shown, in the first embodiment of the bracket 1, the top of the bracket 1 is a mounting surface 111, and a first groove 12 is provided on the mounting surface 111. A first clamp 14 is connected to the bracket body 11 and cooperates with the first groove 12.

[0074] like Figure 3 As shown, in a second embodiment of the bracket 1, the top of the bracket 1 is a mounting surface 111, on which a protrusion 112 is provided. A first groove 12 is provided on the protrusion 112, and a first clamp 14 is connected to the bracket body 11 and cooperates with the first groove 12. Second grooves 13 are provided on both sides of the first groove 12, and two second clamps 15 are connected to the bracket body 11 and cooperate with the second grooves 13. The first limiting part 141 is a bent part on both sides of the first clamp 14, which cooperates with the protrusion 112. The second limiting part 151 is a bent part on one side of the second clamp 15, which cooperates with the end of the bracket body 11. The third connecting part 16 is a through hole at the bottom of the bracket 1, through which the support member 2 passes and is connected to the bracket 1.

[0075] It should be noted that, in this embodiment, to increase the stability of the accumulator 400, such as... Figure 1 , Figure 5 and Figure 6 As shown, the support platform 100 also includes a fixing frame 3. The fixing frame 3 is provided with a fourth connecting part corresponding to the first connecting part at a position coaxial with the first connecting part. The fourth connecting part is used to assist the first connecting part in fixing the accumulator 400.

[0076] Furthermore, in this embodiment, as Figure 1 , Figure 5 and Figure 6 As shown, the fourth connecting part is the third groove 31 on the fixing frame 3. The third groove 31 cooperates with the outer shell of the accumulator 400, placing the accumulator 400 in the third groove 31 and defining the position of the accumulator 400 relative to the bracket body 11.

[0077] Furthermore, in this embodiment, to prevent the accumulator 400 from detaching from the third groove 31, the support platform 100 also includes a third clamp 32, which is connected to the fixing frame 3 and cooperates with the fourth connecting part to assist the first connecting part in fixing the accumulator 400.

[0078] It should be noted that, in this embodiment, the detachable connection between the first clamp 14 and the bracket body 11 includes, but is not limited to, the following:

[0079] In the first connection method, one side of the first clamp 14 is provided with a locking block and the other side is provided with a locking groove at the corresponding positions of the bracket body 11, and the first clamp 14 and the bracket body 11 are engaged and connected.

[0080] The second connection method, such as Figures 1 to 4 As shown, the first clamp 14 has reserved holes on both sides, and fixing bolts are provided in the reserved holes. The bracket body 11 has bolt holes corresponding to the reserved holes. The first clamp 14 is connected to the bracket body 11 by fixing bolts.

[0081] In the third connection method, one side of the first clamp 14 is hinged to the bracket body 11, and the other side is connected to the bracket body 11 by bolts or by snap-fit.

[0082] It should be noted that the connection method between the second clamp 15 and the bracket body 11, and the connection method between the third clamp 32 and the fixing frame 3, can be the same as the connection method of the first clamp 14.

[0083] It should be noted that, in this embodiment, as Figures 1 to 6 As shown, the two brackets 1 of the support platform 100 are in an "I" shape with the support member 2. When the power assembly 300 is fixed by the second connecting part on the bracket 1, the two brackets 1 fix the two ends of the central axis of the power assembly 300, so that the movable outer cylinder of the power assembly 300 rotates stably relative to the central axis. The movable outer cylinder of the power assembly 300 drives the photovoltaic module 500 to track the movement. The support platform 100 provides sufficient space for the movement of the photovoltaic module 500, so the support platform 100 can avoid interfering with the movement of the photovoltaic module 500.

[0084] It should be noted that the support platform 100 directly fixes the power assembly 300 and the accumulator 400 in the photovoltaic device simultaneously through the bracket 1. Compared with fixing the power assembly 300 and the accumulator 400 separately using different fasteners, fixing them directly through the bracket 1 can greatly reduce the space for displacement between the accumulator 400 and the power assembly 300, thereby increasing the stability between the accumulator 400 and the power assembly 300 and increasing the stability of the photovoltaic device.

[0085] It should be noted that, in this embodiment, as Figure 5 and Figure 6 As shown, the support member 2 is either integrally formed or a split structure.

[0086] When the support 2 is integrally formed, the support platform 100 further comprises a first connecting piece 4 and a second connecting piece 5, the first connecting piece 4 is arranged on the support 2, the second connecting piece 5 is connected with an external support structure, and the first connecting piece 4 and the second connecting piece 5 are detachably connected.

[0087] When the support 2 is a split structure, the support 2 comprises a first support 21 and a second support 22, one of the two brackets 1 is connected to one end of the first support 21, the other end of the first support 21 is connected with an external support structure, the other one is connected to one end of the second support 22, the other end of the second support 22 is connected with an external support structure, and the first support 21 and the second support 22 are coaxially arranged.

[0088] In summary, the support platform 100 has the following three embodiments:

[0093] The advantages of this embodiment are: it increases the stability of the photovoltaic device, avoids interference from the support platform 100 on the movement of the photovoltaic module 500, improves the installation efficiency of the accumulator 400 and the power assembly 300, and facilitates subsequent maintenance of the accumulator 400 and the power assembly 300.

[0094] First, in the support platform 100 proposed in this embodiment, the power assembly 300 and the accumulator 400 in the photovoltaic device are fixed directly by the bracket 1. Compared with fixing the power assembly 300 and the accumulator 400 separately using different fasteners, fixing them directly by the bracket 1 can greatly reduce the space for displacement between the accumulator 400 and the power assembly 300, thereby increasing the stability between the accumulator 400 and the power assembly 300 and increasing the stability of the photovoltaic device.

[0095] Secondly, in the support platform 100 proposed in this embodiment, the two brackets 1 and the support member 2 are in an "I" shape, and the second connecting part is located on the mounting surface 111 near the end of the bracket body 11. Therefore, when the power assembly 300 is fixed by the second connecting part on the bracket 1, the two brackets 1 fix the two ends of the central axis of the power assembly 300, so that the movable outer cylinder of the power assembly 300 rotates stably relative to the central axis. The movable outer cylinder of the power assembly 300 drives the photovoltaic module 500 to track the movement. The support platform 100 provides sufficient space for the movement of the photovoltaic module 500, so the support platform 100 can avoid interfering with the movement of the photovoltaic module 500.

[0096] Third, when installing the photovoltaic device, the outer casing of the accumulator 400 is inserted into the first groove 12, and the first clamp 14 can be used to fix the accumulator 400. The central shaft of the power assembly 300 is inserted into the second groove 13, and the second clamp 15 is used to fix the central shaft of the power assembly 300. The installation process is very simple and quick, which improves the installation efficiency of the accumulator 400 and the power assembly 300. Disassembly is also convenient and quick, which facilitates subsequent maintenance.

[0097] Fourth, under the action of the first limiting part 141 on the first clamp 14, the position of the first clamp 14 relative to the bracket body 11 is limited. Under the action of the second limiting part 151 on the second clamp 15, the position of the second clamp 15 relative to the bracket body 11 is limited. This further increases the stability of the first clamp 14 for fixing the accumulator 400 and the stability of the second clamp 15 for fixing the powertrain 300.
