Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and in particular to a photovoltaic support structure. Background Technology

[0002] Photovoltaic power generation is one of the most widely used methods for producing clean electricity, and photovoltaic brackets are an important component in the construction of photovoltaic power plants.

[0003] Most existing ground-mounted photovoltaic (PV) brackets are fixed, while the design and application of tracking brackets are relatively rare, and the structural types are also limited. However, Chinese patent document CN218734079U discloses a novel dual-axis tracking PV bracket, comprising a load-bearing base, a support column, a hydraulic support diagonal rod, a PV panel support frame, a PV panel, and a control system. The support column is connected to the load-bearing base via pre-embedded bolts. A universal joint is located at the top of the support column, connecting to a transverse steel beam in the PV panel support frame. The PV panel is mounted on the PV panel support frame. A ring-shaped clamp is located in the middle of the support column, connecting to the hydraulic support diagonal rod via bolts. A universal joint is located at the top of the hydraulic support diagonal rod, connecting to the PV panel support frame via a connector.

[0004] Although the above technical solution can control the rotation of the photovoltaic panel in both east-west and north-south directions using hydraulic support diagonals, the ends of the east-west and north-south hydraulic support diagonals near the support column are both connected to the ring clamps of the support column. Furthermore, the ends of the east-west and north-south hydraulic support diagonals away from the support column directly act on the photovoltaic panel support frame. Therefore, this support not only suffers from low structural strength but also tends to interfere with each other during bidirectional adjustment, resulting in an unclear force path for the support.

The force path of the support system is clear, and the structural form is relatively simple.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1-4 As shown, this embodiment provides a photovoltaic support frame, including a fixed column 1, a main beam 2, a main beam rotation mechanism 3, and a photovoltaic module support frame 4.

In addition, shims can be set between the main fixed bearing 101 and the main fixed bearing seat to adjust the height and level it, so as to facilitate the installation of the main beam 2.

[0034] In this embodiment, the main beam rotation mechanism 3 includes a main beam rotation frame 301 and a main beam rotation push rod 302. The main beam rotation frame 301 is fixed on the main beam 2 at a position close to any fixed column 1. The main beam rotation push rod 302 is disposed between the main beam rotation frame 301 and the corresponding fixed column 1, and the main beam rotation push rod 302 is used to rotate the main beam 2 in the X direction.

[0035] Specifically, in this embodiment, the main beam rotation push rod 302 is preferably a hydraulic rod; in this embodiment, the main beam rotation mechanism 3 is provided in two sets, and the two sets of main beam rotation mechanisms 3 are respectively located at the positions where the main beam 2 is connected to the two columns, and synchronously drive the main beam 2 to rotate in the X direction.

[0036] In this embodiment, as Figure 4 As shown, one end of the main beam rotating frame 301 of each main beam rotating mechanism 3 is a C-shaped structure, and the other end is a straight structure. The C-shaped end of the main beam rotating frame 301 is fixed at the position where the main beam 2 is connected to the corresponding fixed column 1.

The secondary beam rotation push rod 404 is disposed between the secondary support frame 403 and the main support frame 401, and the secondary beam rotation push rod 404 is used to rotate the secondary beam 402 along the Y direction.

[0039] Specifically, in this embodiment, the secondary beam rotating push rod 404 is preferably a hydraulic rod; in this embodiment, the photovoltaic module support frame 4 is provided in two sets, and the two sets of photovoltaic module support frames 4 are located at both ends of the main beam 2 respectively. As for the number of photovoltaic module support frames 4, those skilled in the art can set it according to the number of photovoltaic modules 01 to be installed. By setting multiple sets of photovoltaic module support frames 4 on the main beam 2, the installation of multiple sets of photovoltaic modules 01 is realized, which further reduces the cost of the support and increases the revenue.

[0040] In this embodiment, the main support frame 401 includes a first support rod 4011 and a second support rod 4012. The first support rod 4011 is vertically fixed to the main beam 2, and the second support rod 4012 is vertically fixed to the first support rod 4011. Multiple second support rods 4012 are provided, and all the second support rods 4012 are arranged on the first support rod 4011 along the extension direction of the first support rod 4011.

[0041] Furthermore, a secondary fixed bearing assembly is provided at the top of each of the second support rods 4012. The secondary fixed bearing assembly includes a secondary fixed bearing 4013 and a secondary fixed bearing seat. The secondary fixed bearing 4013 is fixed to the top of the corresponding second support rod 4012 through the secondary fixed bearing seat.

Furthermore, a shim can be provided between the secondary fixed bearing 4013 and the secondary fixed bearing seat to adjust the height and level the surface, which facilitates the installation of the secondary beam 402.

[0043] In this embodiment, the secondary support frame 403 includes a third support rod 4031 and a fourth support rod 4032. The third support rod 4031 is vertically fixed to the secondary beam 402, and multiple third support rods 4031 are provided.

The fourth support rod 4032 is arranged parallel to the secondary beam 402 and is fixedly connected to each of the third support rods 4031. One end of the secondary beam rotating push rod 404 is rotatably connected to the middle of the fourth support rod 4032, and the other end is rotatably connected to the second support rod 4012 located in the middle. That is, both ends of the secondary beam rotating push rod 404 can rotate in a plane perpendicular to the secondary beam 402.

[0044] It should be noted that, since the main beam rotating frame 301, the main support frame 401 and the secondary support frame 403 in this embodiment are all in the form of brackets, this bracket has high structural strength.

[0045] It should be noted that, as a possible example, for the control of the main beam rotating push rod 302 and the secondary beam rotating push rod 404, which are both hydraulic rods, this embodiment uses an electronic control system to control the extension and retraction lengths of the main beam rotating push rod 302 and the secondary beam rotating push rod 404, thereby controlling the bidirectional rotation of the photovoltaic module 01 to track the solar tilt angle. In this process, since the main beam 2 and the secondary beam 402 rotate through the main beam rotating push rod 302 and the secondary beam rotating push rod 404 respectively, they do not affect each other during bidirectional adjustment. The force path of the support is clear, and the structural form is relatively simple.

[0046] The assembly process of the photovoltaic bracket provided in this embodiment is as follows:

[0047] First, determine the position of each fixed column 1 and install it. Then, install the main fixed bearing 101 on the top of each fixed column 1, ensuring that the main fixed bearings 101 are at the same horizontal height. Next, install the main beam 2 between the main fixed bearings 101. Install the main beam rotating frame 301 at the connection between the main fixed bearings 101 and the main beam 2. Then, install the clamp 102 on each fixed column 1 and connect the two ends of the main beam rotating push rod 302 to the corresponding clamp 102 and the main beam rotating frame 301 respectively. Next, install the main support frame 401 at the corresponding position of the main beam 2. Then, install the secondary fixed bearing 4013 on the upper end of the main support frame 401 and install the secondary beam 402 between the secondary fixed bearings 4013. Then, install the secondary support frame 403 on the secondary beam 402. The secondary support frame 403 is reconnected to the main support frame 401 through the secondary beam rotating push rod 404. Finally, install the photovoltaic module 01 to complete the assembly of the entire system.

[0048] The photovoltaic support system provided in this embodiment is used as follows:

[0049] The electronic control system controls the extension and retraction length of the main beam rotation push rod 302, causing the main beam rotation push rod 302 to push and pull the main beam rotation frame 301, thereby causing the main beam 2 to rotate in the X direction, and driving the photovoltaic module support frame 4 and the photovoltaic module 01 to rotate, so as to realize the rotation adjustment of the photovoltaic module 01 in the X direction. At the same time, the electronic control system controls the extension and retraction length of the secondary beam rotation push rod 404, causing the secondary beam 402 to rotate in the Y direction, and driving the photovoltaic module 01 to rotate, so as to realize the rotation adjustment of the photovoltaic module 01 in the Y direction, thereby enabling the photovoltaic module 01 to track the angle of sunlight in both directions.

[0050] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model.
