Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, in particular to a row-connected photovoltaic support. Background Art

[0002] In recent years, China has accelerated the construction of a "new power system with new energy as the main body", and the new energy photovoltaic industry has obtained a new round of rapid development. In photovoltaic power generation project construction, fixed supports, that is, fixed-inclination photovoltaic module supports, are the most widely used because of their convenient design, manufacture and installation, and reasonable cost. It generally arranges several frame cross-sections composed of columns, inclined beams and bracing longitudinally, with purlins erected on the upper part. Photovoltaic modules are sequentially fixed and installed above the purlins through bolt connection pairs one by one. In areas with poor geological conditions, low bearing capacity, and possible uneven settlement in the field area, it will affect the stable bearing of the photovoltaic support on the photovoltaic panel module and the stable light reception of the photovoltaic panel module.

[0003] Therefore, a photovoltaic support with the publication number of CN220673660U can effectively bear photovoltaic panels as a bearing foundation by setting a truss structure and a column structure. At the same time, a pile foundation structure buried in the placement surface is set at the bottom of the column structure, which can increase the contact area between the photovoltaic support and the placement surface, and further improve the bearing stability of the photovoltaic support. In addition, the setting of the settlement compensation device can adjust the distance between the column structure and the pile foundation structure. With this setting, when the pile foundation structure in the placement surface settles, the distance between the column structure and the pile foundation structure can be increased through the settlement compensation device, avoiding the skew of the truss structure and the column structure, ensuring the stable height and angle bearing of the photovoltaic panels, and avoiding the occurrence of situations such as the slippage of the photovoltaic panels or insufficient light reception, thereby effectively overcoming the defects that the bearing stability of the photovoltaic support may decline due to settlement in the area where the photovoltaic support is set and the unstable light reception of the photovoltaic panels in the prior art.

[0004] However, when dealing with the need for a very high design elevation of photovoltaic panels, there are great requirements for the penetration depth and diameter of the piles, which will result in a high cost for the pile foundation of the photovoltaic project, and the overall anti-overturning ability of the photovoltaic support is poor, and there are disadvantages in dealing with complex environments. Content of the Utility Model

[0005] In order to overcome the defects of the prior art, the technical problem to be solved by the utility model is to provide a row-connected photovoltaic support, which can greatly reduce the penetration depth of the piles and the diameter of the piles, and reduce the pile foundation cost of the photovoltaic project.

[0006] To achieve this purpose, the utility model adopts the following technical solutions:

[0007] A row-connected photovoltaic support provided by the utility model comprises two pile foundation columns. A photovoltaic support assembly is arranged at the top end of each pile foundation column. The photovoltaic support assembly is used for carrying photovoltaic panels. An inter-column support assembly is arranged between the two pile foundation columns.

[0008] The support assembly comprises four support hoops. Every two support hoops are respectively installed on the pile foundation column in an up-and-down manner. A support cross steel pipe is connected between the two support hoops located above. A connecting plate is fixedly arranged in the middle of the support cross steel pipe. A support inclined steel pipe is connected between the support hoop located below and the connecting plate.

[0009] In a preferred technical solution of the utility model, both ends of the support cross steel pipe are hinged to the support hoops through adjusting sleeves. Both ends of the support inclined steel pipe are respectively hinged to the support hoops and the connecting plate through adjusting sleeves.

[0010] In a preferred technical solution of the utility model, a plurality of through holes are equidistantly arranged on the adjusting sleeve. Positioning holes matched with the through holes are arranged on the support cross steel pipe and the support inclined steel pipe.

[0011] In a preferred technical solution of the utility model, the support assembly comprises an upper hoop, a lower hoop, a column, a support rod and an inclined beam. The upper hoop and the lower hoop are fixedly installed on the pile foundation column. The column is fixed to the upper hoop and the lower hoop through bolts. The bottom end of the support rod is fixed to the lower hoop through bolts. The top end of the support rod is fixedly connected to the inclined beam. A plurality of purlins are arranged on the inclined beam. The photovoltaic panel is fixedly installed on the purlins.

[0012] The beneficial effects of the utility model are as follows:

[0013] The row-connected photovoltaic support provided by the utility model uses an inter-column support assembly to connect the pile foundation columns of two groups of photovoltaic units, changing the original independent single-pile structure into a two-pile row-connected structure. Under the action of a horizontal thrust, the horizontal overturning force is converted into a tension and compression effect of two piles, which is applicable to rock and soil with poor horizontal resistance, can make full use of the vertical bearing capacity of the rock and soil, can greatly reduce the embedded depth of the piles and reduce the diameter of the piles, and reduce the pile foundation cost of the photovoltaic project.

[0023] The technical solution of the present utility model will be further described below with reference to the accompanying drawings and through specific embodiments.

[0024] As shown in the figure, this embodiment provides a row-connected photovoltaic support, including two pile foundation columns 1. The top of the pile foundation column 1 is provided with a photovoltaic support assembly 2, and the photovoltaic support assembly 2 is used to carry photovoltaic panels 3. A column-interval support assembly 4 is arranged between the two pile foundation columns 1. The support assembly includes four support hoops 5. Every two support hoops 5 are respectively installed on the pile foundation column 1 up and down. A support cross steel pipe 6 is connected between the two support hoops 5 located above. A connecting plate 7 is fixedly arranged in the middle of the support cross steel pipe 6. A support diagonal steel pipe is connected between the support hoop 5 located below and the connecting plate 7. Both ends of the support cross steel pipe 6 are hinged to the support hoop 5 through an adjusting sleeve 9. Both ends of the support diagonal steel pipe 8 are respectively hinged to the support hoop 5 and the connecting plate 7 through an adjusting sleeve 9. The column-interval support assembly 4 connects the pile foundation columns 1 of two groups of photovoltaic strings, changing the original independent single-pile structure into a two-pile row-connected structure. Under the action of the horizontal thrust, the horizontal overturning force is transformed into a tension-compression effect of the two piles, which is applicable to the rock and soil with poor horizontal resistance, can make full use of the vertical bearing capacity of the rock and soil, can greatly reduce the embedded depth of the pile and the diameter of the pile, and reduce the pile foundation cost of the photovoltaic project.

[0025] Further, a plurality of through holes 10 are equidistantly arranged on the adjusting sleeve 9, and positioning holes matched with the through holes 10 are arranged on the support cross steel pipe 6 and the support diagonal steel pipe 8. Due to the errors in on-site construction, the distance between the pile foundation columns 1 between two groups of photovoltaic strings will have a size different from that in the construction drawing, which will cause the column-interval support to be unable to be installed. Through the through holes 10 of the adjusting sleeve 9, the connecting bolts can selectively use one of them according to the distance, and freely adjust the lengths of the column-interval support cross steel pipe 6 and the support diagonal steel pipe 8, so that the column-interval support can be smoothly installed on the piles between two groups of photovoltaic strings.

[0026] Among them, the support assembly includes an upper hoop 12, a lower hoop 13, a column 14, a support rod 15 and an inclined beam 16. The upper hoop 12 and the lower hoop 13 are fixedly installed on the pile foundation column 1. The column 14 is fixed to the upper hoop 12 and the lower hoop 13 through bolts. The bottom end of the support rod 15 is fixed to the lower hoop 13 through bolts. The top end of the support rod 15 is fixedly connected to the inclined beam 16. A plurality of purlins 17 are arranged on the inclined beam 16, and the photovoltaic panel 3 is fixedly installed on the purlins 17.

[0027] The present invention is described through preferred embodiments. Those skilled in the art know that without departing from the spirit and scope of the present invention, various changes or equivalent replacements can be made to these features and embodiments. The present invention is not limited by the specific embodiments disclosed herein, and other embodiments falling within the scope of the claims of this application belong to the scope of protection of the present invention.
