Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic product testing technology, and in particular relates to pile foundation. Background Technology

[0002] As an important component of photovoltaic power generation systems, photovoltaic brackets directly affect the operational safety, damage rate, and construction investment of photovoltaic modules. Therefore, it is essential to conduct quality testing after the photovoltaic brackets are manufactured and processed. For existing photovoltaic bracket products to undergo verification experiments, the foundation of the bracket must be firmly connected to the ground, which requires corresponding pile foundations to fix the bracket to the ground.

[0003] However, due to the diverse foundation styles of existing support products, various foundations need to be fabricated on the ground to accommodate different support products. This results in the need to occupy a large area of ​​the factory to manufacture foundations of different types, sizes, and spacings, leading to high costs in verification testing time, foundations, and site. Therefore, designing pile foundations is essential. Utility Model Content

Due to the variety of foundation styles for support products, various foundations need to be constructed on the ground to accommodate different support products. This results in the need to occupy a large area of ​​the factory to manufacture foundations of different types, sizes, and spacings, leading to high costs in verification testing time, foundations, and site.

[0029] In this embodiment, the entire device can be lifted by a crane using the lifting ring 8, and then placed in different locations, making the verification site flexible. At the same time, the base 5 can be firmly fixed to the ground using the strip groove 6 and external bolts. Then, the number of sliding seats 2 can be increased or decreased according to the shape or size of the photovoltaic support column. At this time, the column is inserted through the opening on the base body 1, and its bottom end is supported and limited by the inner bottom wall of the base body 1. Then, the sliding seat 2 is slid so that the clamping plate 15 is pressed tightly against the surface of the column. At the same time, the fastening bolt 13 is passed through the reserved groove 9 and the sliding seat 2. Then, the anti-loosening washer 12 is sleeved on the surface of the fastening bolt 13. Then, the fastening nut 11 is screwed onto the surface of the fastening bolt 13, and the bottom end of the anti-loosening washer 12 is firmly pressed and fixed to the inner bottom wall of the sliding seat 2, so as to achieve a firm clamping and fixing of different photovoltaic support columns of different shapes or sizes.

[0030] In a further preferred embodiment of the present invention, the sliding seat 2 is L-shaped, and the sliding seats 2 at the top of the base body 1 and the bottom wall of the base body 1 are distributed at equal angles and cross each other.

[0034] In a further preferred embodiment of the present invention, the upper opening inside the base body 1 is O-shaped, and the lower opening inside the base body 1 is a cross-shaped support plate.

[0035] In this embodiment, the opening shape of the base body 1 itself allows the column to be inserted from the top of the base body 1 and supported on the inner bottom wall of the base body 1.

[0036] In a further preferred embodiment of this utility model, four corners at the top of the base body 1 are fixedly connected with lifting rings 8 by bolts, and the lifting rings 8 have O-shaped holes.

[0037] In this embodiment, the lifting ring 8 is used to facilitate easy lifting and transfer of the entire device.

[0038] In a further preferred embodiment of the present invention, anti-slip textures 10 are provided at equal intervals on one side of the clamping plate 15, and the anti-slip textures 10 are arc-shaped.

[0039] In this embodiment, the arc-shaped anti-slip texture 10 is used to improve the anti-slip properties of the clamping plate 15 and the column surface for clamping and fixing.

[0040] Example 2

[0041] Based on Embodiment 1, a preferred embodiment of the pile foundation provided by this utility model is as follows: Figures 1 to 5 As shown: A locking block 16 is fixedly connected to the upper end of the inner wall of the sliding seat 2. A bolt hole 17 is provided at the middle position of the top of the locking block 16. A locking groove 18 is provided at the upper end of one side of the clamping plate 15. A fixing bolt 14 that passes through the clamping plate 15 is movably connected to the top of the clamping plate 15. The bottom end of the fixing bolt 14 and the inside of the bolt hole 17 form a threaded engagement structure.

[0042] In this embodiment, when the clamping plate 15 is severely worn and needs to be replaced, the fixing bolt 14 can be rotated until it is completely disengaged from the bolt hole 17, and then the clamping plate 15 can be pulled to disengage it from the sliding seat 2. During installation, the clamping plate 15 is clamped toward the sliding seat 2 and the clamping block 16 is clamped into the slot 18. Then the fixing bolt 14 is tightened into the bolt hole 17, thereby enabling quick disassembly and assembly between the clamping plate 15 and the sliding seat 2.
