Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module installation technology, and specifically provides a flexible photovoltaic support structure. Background Technology

[0002] Photovoltaic modules, as the core of photoelectric conversion, are typically installed in photovoltaic support systems via connection devices. Photovoltaic support systems are mainly divided into two categories: rigid supports and flexible supports.

[0003] 1. Rigid brackets mainly use two methods: bolt connection and pressure block connection to secure the photovoltaic modules to the rigid purlins. The bolt connection directly connects the module frame to the purlins; while the pressure block connection uses the flanges of the pressure block to press against the module frame, and then connects the bottom to the bolts and the rigid purlins, thus achieving stable installation of the photovoltaic modules.

[0004] 2. Flexible support mainly adopts two connection methods: bolt connection and bolt-block combination connection. Bolt connection refers to the photovoltaic module frame, connecting plate and clamp tightly working together with bolts to hug the steel strands of the flexible support and form a fixed connection structure. The bolt + clamp combination connection method is to install a clamp on the basis of bolt connection. The flange of the clamp presses on the top of the module frame. The module connecting clamp, module connecting plate and clamp are connected by bolts, which can effectively increase the contact area and improve the stability and durability of the connection.

[0005] However, in certain special scenarios, such as in subsidence areas or in the context of solar-fishery integration, it is difficult to install and fix the photovoltaic panels directly under the photovoltaic support bracket using the traditional methods mentioned above. Therefore, it is necessary to design a flexible photovoltaic bracket that can meet the needs of special scenarios. Utility Model Content

[0006] To solve the above problems, this utility model provides a flexible photovoltaic support structure.

[0007] This utility model provides a flexible photovoltaic support structure, including a first pressure block assembly and a second pressure block assembly, which are C-shaped structures with openings facing opposite directions. The first pressure block assembly is connected to a fixed housing, and the second pressure block assembly is connected to a fixing pin outer plate. The fixed housing has a fixing groove, and a self-locking component is provided between the fixing groove and the fixing pin outer plate. Both the first and second pressure block assemblies open away from the self-locking component. A first photovoltaic panel is installed in the opening of the first pressure block assembly, and a second photovoltaic panel is installed in the opening of the second pressure block assembly. The self-locking component includes an arrow-shaped fixing pin and a fixing lock located in the fixing groove. The arrow-shaped fixing pin is fastened to the fixing lock. A clamp is connected to the lower end of the fixed housing, and a steel strand is connected to the clamp.

[0008] Furthermore, the first pressure block assembly includes an upper pressure block and a lower pressure block of L-shaped structure, which are combined to form a C-shaped structure; the second pressure block assembly includes an upper pressure block and a lower pressure block of L-shaped structure, which are combined to form a C-shaped structure; when the photovoltaic panel 1 is clamped between the upper pressure block and the lower pressure block, and the photovoltaic panel 2 is clamped between the upper pressure block and the lower pressure block, the upper pressure block and the lower pressure block are locked together by bolts.

[0009] Furthermore, the fixed lock includes a clamp with an arrow-shaped hook at one end, a support column between the clamps, a connecting column vertically mounted on the support column, the connecting column being parallel to the clamp and a compression spring being provided between the connecting column and the clamp; the fixed lock is connected to the fixed housing through the connecting column, specifically the connecting column being fixed on the groove wall near the pressure block assembly on the side of the fixed groove, and the arrow-shaped hook being positioned away from the connecting column.

[0010] Furthermore, the end of the arrow-shaped fixing pin near the fixing groove is provided with an arrow-shaped head that matches the arrow-shaped hook.

[0011] Furthermore, the fixed housing is connected to the upper pressure block one, and the arrow-shaped fixing pin is connected to the upper pressure block two.

[0012] Furthermore, the arrow-shaped fixing pin is connected to the upper pressure block via the outer plate of the fixing pin.

[0013] Furthermore, the arrow-shaped hook includes a straight section 1 and a conical section 1 extending inward from the inner end of the clamp. The conical section 1 is located at the end of the straight section 1 away from the connecting post, and the diameter of the conical section 1 gradually decreases from the outside to the inside. The arrow-shaped head includes a straight section 2 and a conical section 2 extending from the inside to the outside. The conical section 2 is located at the end of the straight section 2 away from the outer plate of the fixing pin, and the diameter of the conical section 1 gradually decreases from the inside to the outside.

[0014] Furthermore, the clamp includes a central connecting hole, the diameter of which is larger than the diameter of the steel strand.

[0015] Furthermore, the clamp is bolted to the bottom of the fixed housing.

[0016] Furthermore, the support structure includes a support frame, with steel strands fixed to the support frame. After all photovoltaic panels are installed, a second pressure block assembly is installed on the left end of the first photovoltaic panel, and a first pressure block assembly is installed on the right end of the last photovoltaic panel. A fixing housing with a fixing groove and a fixing lock is installed on the left side of the second pressure block assembly, and a fixing pin outer plate and an arrow-shaped fixing pin are installed on the right side of the first pressure block assembly. Here, the fixing housing and the fixing pin outer plate are both connected to the support frame or the steel strands.

[0017] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0018] 1. The bracket structure in this utility model uses a sliding installation method. After the photovoltaic panels come into contact and collide, the self-locking device is triggered. After the self-locking device is activated, it can effectively limit the horizontal displacement of the photovoltaic panels. The clamp located directly below the self-locking device not only ensures the stable sliding of the photovoltaic panels on the steel strand, but also effectively limits the vertical displacement of the photovoltaic panels. This solution combines the sliding installation method with the self-locking structure to achieve safe and efficient construction.

[0019] 2. Compared with the traditional support structure that requires operation from below, the support structure of this utility model can be used in special scenarios where it is inconvenient to operate from below, such as subsidence areas, solar-fishery integration, and sewage treatment plants, which can greatly improve work efficiency and personnel safety in special scenarios.
