Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a photovoltaic support column clamp anti-slip device and a photovoltaic support. Background Technology

[0002] Typically, 26 or more modules are connected into a string and installed on a photovoltaic (PV) support system. Dual-column PV supports offer high lateral stiffness and strong wind resistance. The column base joints are generally designed as hinged connections, and inter-column bracing is installed between the front and rear columns. The foundation design is relatively simple, making them widely used in new energy PV projects. (Refer to...) Figure 1 The inter-column diagonal bracing is generally designed in the shape of " / " or inverted "V". The upper support point is connected to the connector under the diagonal beam by bolts, and the lower support point is connected to the column by a clamp with adjustable vertical position. The above connection method can better adapt to changes in terrain and mitigate the impact of foundation construction deviations on the installation of the upper support.

[0003] The lower support point of the diagonal brace is connected to the column via an adjustable vertical clamp. The friction between the clamp and the column balances the vertical component of the support axial force. Under adverse conditions such as heavy snowfall, strong winds, and freezing rain, when the friction cannot balance the vertical component of the support axial force, the lower support point undergoes vertical slippage deformation, which in turn causes vertical deformation at the mid-span of the diagonal beam. This deformation of the support may ultimately lead to component damage. During the design process, the friction coefficient and contact surface pressure between the clamp and the column are difficult to determine, and the friction force cannot be accurately calculated. The design is mainly based on engineering experience, resulting in low reliability. Utility Model Content

[0004] The primary objective of this invention is to provide a photovoltaic support column clamp anti-slip device, which can prevent the vertical slippage of the clamp at the lower support point of the diagonal brace between the support columns, thereby causing deformation of the upper structure of the support.

[0005] The second objective of this utility model is to provide a photovoltaic support bracket, which includes the photovoltaic support bracket column clamp anti-slip device as described above.

[0006] This utility model provides a photovoltaic support column clamp anti-slip device, which includes a support structure. One end of the support structure is connected to the column diagonal brace clamp, and the other end is supported on the top of the pre-embedded steel pipe in the foundation or the top of the concrete foundation.

[0007] Preferably, the column diagonal brace clamp is an upper clamp;

[0008] The support structure includes a lower clamp, which is fixed to the support column;

[0009] A support rod is provided between the upper end of the lower clamp and the upper clamp, and the lower end of the lower clamp is supported on the top of the pre-embedded steel pipe in the foundation or the top of the concrete foundation.

[0010] Preferably, the two ends of the support rod are connected to the upper clamp and the lower clamp respectively by bolts.

[0011] Preferably, the supporting structure is a steel structure, with the upper end of the steel structure installed on the column diagonal brace clamp, and the other end supported on the top of the foundation embedded steel pipe or the top of the concrete foundation.

[0012] A photovoltaic support structure includes a photovoltaic support column clamp anti-slip device as described above.

[0013] Preferably, it includes foundation embedded parts and support columns;

[0014] One end of the support column is inserted into the foundation embedded part.

[0015] Preferably, the support column and the foundation embedded parts are connected by limiting bolts and through bolts.

[0016] Preferably, the photovoltaic support also includes a column brace, the brace clamp is installed on the support column, and the column brace is hinged to the brace clamp.

[0017] Beneficial effects:

[0018] By adding a supporting structure to the existing column diagonal bracing clamps, the vertical component of the support axial force can be transferred to the foundation, resulting in a clearer force transmission path and higher node reliability. This eliminates the risk of column clamp slippage and ensures the stability of the lower support point of the column diagonal bracing. When the upper structure of the support bears a large load, the inter-column diagonal bracing can reliably support the inclined beams, preventing the overall support structure from deforming.

[0028] In this embodiment, a supporting structure is added to the existing column diagonal bracing.

The support structure is a steel structure, with the upper end of the steel structure installed on the column diagonal brace clamp, and the other end supported on the top of the pre-embedded steel pipe in the foundation or the top of the concrete foundation. The steel structure includes vertical supports, diagonal supports, etc., meaning that it is sufficient as long as it can transfer the vertical component of the column diagonal brace clamp to the foundation.
