Description

TECHNICAL FIELD

[0001] The utility model belongs to photovoltaic support technical field, concretely relates to a photovoltaic support with multi-area connecting node. BACKGROUND

[0002] The photovoltaic support system is an important component of the photovoltaic power station, and its stability directly affects the installation angle and power generation efficiency of the photovoltaic panel. In the existing photovoltaic support structure, the single-pile double-column design is widely used. This structure usually fixes the front and rear columns on the pipe pile through a hoop, and uses the friction between the hoop and the pipe pile to maintain the stability of the support. However, this structure has some technical problems in practical application.

[0003] Due to many uncertain factors such as on-site construction technology and construction method, the friction between the single hoop and the pipe pile cannot meet the changing weather conditions, and the hoop and the pipe pile are prone to slight deformation due to small amplitude vibration. If the local wind pressure exceeds the specified limit value during strong wind weather, the stability of the overall structure of the support and the inclination angle of the photovoltaic panel will change, resulting in a decrease in the power generation of the project. At the same time, the connecting bolts will loosen when subjected to vibration, which can easily cause the overall instability of the structure.

[0004] Therefore, there is a need for a photovoltaic support with multi-area connecting node that can improve the stability of the overall structure and ensure that the inclination angle of the photovoltaic panel remains unchanged. SUMMARY

[0005] The purpose of the utility model is to provide a photovoltaic support with multi-area connecting node that can improve the stability of the overall structure and ensure that the inclination angle of the photovoltaic panel remains unchanged.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0008] The further improvement of the technical scheme of the utility model is that the support members on the two columns are correspondingly arranged or arranged in an up-down staggered manner.

[0009] The further improvement of the utility model technical scheme lies in that the support piece arranged on the front side column of the pipe pile is located between the upper cross arm and the lower cross arm, and the support piece arranged on the rear side column of the pipe pile is located between the lower cross arm and the hoop.

[0010] The further improvement of the utility model technical scheme lies in that the support piece comprises a wing plate connected with the column through a bolt and a web plate integrally formed with the wing plate and in contact with the outer wall of the pipe pile.

[0011] The further improvement of the utility model technical scheme lies in that the wing plate and the web plate are both rectangular structures, and the included angle between the web plate and the wing plate is a right angle.

[0012] The further improvement of the utility model technical scheme lies in that the wing plate is a rectangular structure, the web plate is an arc structure matched with the shape of the outer wall of the pipe pile, and the included angle between the virtual connecting line of the two ends of the web plate and the wing plate is a right angle.

[0013] The further improvement of the utility model technical scheme lies in that the contact surface between the web plate and the pipe pile is paved with an anti-skid rubber layer.

[0014] The further improvement of the utility model technical scheme lies in that an inclined brace is obliquely arranged between the two columns and above the upper cross arm, and a horizontal beam is horizontally arranged between the two columns and above the inclined brace.

[0015] The further improvement of the utility model technical scheme lies in that the frame unit comprises an inclined beam obliquely arranged on the two columns and connected with the upper ends of the two columns respectively, and a plurality of purlins for bearing the photovoltaic panels which are arranged along the oblique direction of the inclined beam.

[0016] The further improvement of the utility model technical scheme lies in that the upper and lower ends of the purlin are connected with the photovoltaic panel and the inclined beam through bolts respectively, and one side of the purlin is provided with an L-shaped purlin support matched therewith; and the front and rear ends of the inclined beam are connected with the hoops on the pipe pile through inclined struts.

[0017] Thanks to the above technical scheme, the utility model has the following technical progress:

[0018] The photovoltaic support with the multi-area connecting node can effectively improve the stability of the overall structure, ensure that the inclination angle of the photovoltaic panel remains unchanged under various weather conditions, increase the contact area between the support and the pipe pile through the two support pieces arranged in an up-down staggered manner, and effectively avoid hoop deformation, overall deformation of the support, structural instability and the like.

[0019] The two supporting pieces increase the contact area with the pipe pile, thereby improving the stability of the whole support system, reducing the shaking and displacement caused by wind force or other external force, and the up-down staggered arrangement of the two supporting pieces helps to disperse the load, reduces the pressure of a single connecting point, effectively prevents the deformation of the hoop and the deformation of the whole support, thereby avoiding structural instability.
