Description
Technical Field
[0001] This utility model relates to the field of mountain photovoltaic support, and in particular to a double-tube photovoltaic support that can be adjusted according to the terrain. Background Technology
[0002] With the ever-increasing global demand for renewable energy, solar energy, as a clean and renewable energy source, has received widespread attention for its development and utilization. In the field of photovoltaic power generation, photovoltaic power plants, with their advantages of high efficiency and low cost, are gradually becoming an important development direction for solar power generation technology. The principle of this type of power plant is as follows: under the irradiation of electromagnetic waves of a frequency higher than a certain specific frequency (this frequency is called the threshold frequency), electrons inside certain materials absorb energy and escape to form an electric current, i.e., photovoltaic power generation, realizing the efficient conversion of solar energy into electrical energy.
[0003] However, in the practical application of photovoltaic power generation, mountainous and complex terrain has a significant impact on the installation of photovoltaic supports. Steep slopes make it difficult to level the steel supports. Historically, high-strength prestressed concrete pipe piles can be used to adjust the pile top elevation in soft soil and desert areas. However, in some project areas with hard rock or pebbles, pipe piles cannot be installed. Using cast-in-place concrete piles would result in inconsistent foundation heights. Furthermore, pile driving in mountainous terrain is complex; minimizing the number of piles can significantly shorten the construction period. Therefore, using a single-column method can greatly increase construction convenience. However, achieving the overall stability of the photovoltaic support requires very large steel columns, leading to an increase in the amount of steel used in the photovoltaic support system. Utility Model Content
[0004] To address existing problems, this utility model provides a double-tube photovoltaic support system that can be adjusted according to terrain. It aims to reduce the number of steel beams in the support system by optimizing the design of the steel pipe columns. While reducing the number of steel beams, it can effectively increase the overall rigidity and stability of the direct structure, and at the same time, it is easy to adjust and convenient to construct.
[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0040] Example 1
[0041] like Figure 1 The diagram illustrates a terrain-adjustable double-sleeve photovoltaic (PV) support system, comprising two pre-embedded sleeves 2 fixed to the front and rear columns 1 in the pile foundation 1, a first connecting angle steel 3 connecting the pre-embedded sleeves of the front and rear steel pipe columns 4, the front and rear steel pipe columns 4, a second connecting angle steel 5 connecting the front and rear steel pipe columns 4, column clamps 6, and front and rear diagonal supports 7 respectively connected to both ends of the diagonal beam 8 that fixes the PV support system. The lattice-type column system formed by the front and rear steel pipe columns 4 and the supports between the columns has the ability to withstand greater loads and cope with more complex working conditions, while simultaneously reducing the amount of steel used. It significantly improves the overall stability of the PV support system, effectively reduces the negative impact of natural factors such as earthquakes, wind, and snowfall on the support system, and ensures the stable operation of the system.
[0042] like Figure 2 As shown, the front and rear steel pipe columns 4 extend into the pre-embedded sleeves of the front and rear steel pipe columns 4 respectively, and are clamped and fixed by locking bolts 10 evenly distributed on the pre-embedded sleeves of the front and rear steel pipe columns 4 respectively. Figure 2 (b) is Figure 2 (a) Enlarged cross-sectional view; Figure 2(b) shows three locking bolts 10 with an included angle of 120º between them; the locking bolts 10 pass through the bolt holes at the top of the pre-embedded sleeve 2 of the column to clamp and fix the steel pipe column 4.
[0043] like Figure 2 As shown, the cylindrical wall of the pre-embedded sleeve 2 of the column has a through hole, and a through bolt 11 is installed in the through hole. The through bolt 11 can contact the bottom of the steel pipe column 4 to support the weight of the steel pipe column 4. The through bolt 11 can also leave a certain gap with the bottom of the steel pipe column 4 and not contact the bottom of the steel pipe column 4 to prevent the friction of the locking bolt 10 from being unable to support the weight of the photovoltaic module and causing it to sink and the photovoltaic module to be too close to the ground.
[0044] like Figure 3 As shown, the pre-embedded sleeves connecting the front and rear steel pipe columns 4 are connected by the first connecting angle steel 3. Both the front and rear steel pipe columns 4 are equipped with lugs 12 with bolt holes, which are used to connect the second connecting angle steel 5. Figure 1 As shown, there are at least two second connecting angle steels 5, which help to strengthen the connection between the front and rear steel pipe columns 4 and improve the stability of the support for the photovoltaic modules above.
[0045] like Figure 4 As shown in (a), the column clamp 6 includes two elongated fixing plates 13; each fixing plate 13 has at least two arc-shaped protrusions 14 and several fixing holes 15; the arc-shaped protrusions 14 of the two fixing plates 13 are arranged opposite to each other to form two columnar cavities. Using the column clamp 6, which includes two elongated fixing plates 13 and arc-shaped protrusions 14, the front and rear steel pipe columns 4 can be clamped more tightly, improving the overall stability of the support; at the same time, this design is also convenient for installation and adjustment.
[0046] like Figure 4 As shown, the fixing holes 15 are distributed on both sides of the arc-shaped protrusion 14, used to lock the fixing plate 13 to clamp the front and rear steel pipe columns 4. It can be seen that because the two arc-shaped protrusions 14 are evenly distributed on the fixing plate 13, the fixing holes 15 are also correspondingly evenly distributed on the fixing plate 13, allowing the two fixing plates 13 to fit tightly together. The fixing holes 15, distributed on both sides of the arc-shaped protrusion 14, can connect the front and rear diagonal supports 7 and ensure the stability of the column clamp 6, preventing it from loosening under stress. The cylindrical cavity is used to accommodate the steel pipe column 4, and the size of the cylindrical cavity should be adapted to the thickness of the steel pipe column 4. Figure 4 As shown in (a), the two elongated fixing plates 13 are of different lengths, with connecting holes 16 on the longer fixing plate 13 located at both ends of the strip plate for connecting the front and rear diagonal supports 7. Locking bolts 10 pass through the fixing holes 15, and tightening the bolts helps to increase the clamping force. Figure 4 (b) is Figure 4 (a) A bottom view of the medium-length fixing plate 13 shows that the fixing holes 15 are also evenly distributed on the fixing plate 13, so that the two fixing plates 13 fit together and are clamped.
[0047] like Figure 5 As shown, the column clamp 6 surrounds the front and rear steel pipe columns 4 to form a clamp, and both sides of the column clamp 6 are connected to the front and rear diagonal supports 7 respectively. The fixing holes 15 are distributed on both sides of the arc-shaped protrusion 14, and are used to lock the fixing plate 13 to clamp the front and rear steel pipe columns 4. The connecting holes 16 provided on the longer fixing plate 13 of the two fixing plates 13 are distributed at both ends of the strip plate, and are used to connect the front and rear diagonal supports 7.
[0048] like Figure 6 As shown in (a), the double-tube photovoltaic support in this embodiment also includes front and rear column triangular connectors 17, and the front and rear steel pipe columns 4 are connected to the inclined beam 8 through the front and rear column triangular connectors 17. Figure 6 (b) is Figure 6 (a) Cross-sectional view, Figure 6 (b) shows that the cross-section of the inclined beam 8 is a rectangle with an opening; bolt holes are provided on the two opposite narrow faces of the inclined beam 8 that are not open, for fixing the inclined beam 8 and the column triangular connector 17.
[0049] like Figure 7 As shown, the front and rear column triangular connector 17 includes a base plate 18 and two opposing wing plates 19 perpendicularly connected to the base plate 18. The base plate 18 is rectangular, and two base plate connection holes are evenly arranged on the base plate 18 for fixing the inclined beam 8 of the photovoltaic bracket. The wing plates 19 are triangular, and there is a wing plate connection hole in the center of the wing plate 19 for connecting the steel pipe column 4. The front and rear steel pipe columns 4 are respectively bolted to the inclined beam 8 of the photovoltaic bracket through the front and rear column triangular connector 17. Figure 7 (a) is a front view of the column triangular connector 17. Figure 7 (b) is Figure 7 (a) Left view, Figure 7 (c) is Figure 7 (a) Bottom view. By introducing the front and rear column triangular connectors 17, which include the design of the base plate 18 and the wing plate 19, the front and rear steel pipe columns 4 can be connected to the inclined beam 8 of the photovoltaic bracket more effectively, improving the load-bearing capacity of the bracket and increasing its stability; the wing plate 19 is triangular, which enhances the stability of the structure, and the wing plate connection hole facilitates bolt connection.
[0050] like Figure 8 As shown, the front and rear inclined supports 7 are respectively connected to both ends of the inclined beam 8 of the fixed photovoltaic bracket, and the connection method can be bolt connection or hinge connection. Figure 8 (b) is Figure 8(a) shows a cross-sectional view where bolt holes are provided on the unopened wide face of the inclined beam 8 for fixing the inclined beam 8 and the inclined support 7 together.
[0051] like Figure 9 As shown, the inclined beam 8 of the photovoltaic bracket is connected to the purlin 9 through the angle steel purlin bracket, and the purlin 9 is used to bolt to the photovoltaic panel.
[0052] The front and rear inclined supports 7 can also be equipped with adjusting sleeves, which are used to adjust the length of the front and rear inclined supports 7. The adjusting sleeves help to adjust the tilt angle of the photovoltaic panel and are a supplementary tilt angle adjustment method; the original solution can adjust the tilt angle of the photovoltaic panel by adjusting the included angle between the column clamp 6 and the inclined support 7.
[0053] This utility model's photovoltaic support design significantly improves the overall stability of the photovoltaic support system, effectively reducing the negative impacts of natural factors such as earthquakes, wind, and snowfall on the support, ensuring stable system operation. The lattice column system formed by the front and rear steel pipe columns and the inter-column supports has the ability to withstand greater loads and cope with more complex working conditions, while reducing steel consumption. The connection between the double columns and the foundation pre-embedded sleeves can be flexibly adjusted in height according to the actual site conditions, with a wide adjustment range, reducing construction difficulty. In addition, all component ear plates, hanging holes, and openings are processed in the factory, and all on-site installation uses bolt connections, avoiding welding operations, thereby improving the convenience of construction in areas with unfavorable terrain conditions. Compared with other photovoltaic supports, this project is suitable for areas with geology such as gravel, pebbles, or where precast pipe piles cannot be constructed. Drilled cast-in-place piles are required as the foundation for the photovoltaic support, and embedded parts are pre-embedded before the concrete is poured at the top of the cast-in-place piles, which can shorten the overall construction period.
[0054] Due to the small size and light weight of individual steel components, on-site workers do not need to carry welding machines or other electromechanical equipment in areas difficult for construction machinery to access, significantly improving personnel mobility during construction. Simultaneously, the entire structural system enhances the overall safety and environmental friendliness of the photovoltaic support system, enabling safe and environmentally friendly construction without electricity or open flames. This structural design not only reduces the construction period of the power plant but also increases the stability of the photovoltaic support system and reduces maintenance costs, which is of great significance for promoting the further development and application of mountain photovoltaic power generation technology.
[0055] Specific operating principle:
[0056] Before the concrete is poured into the cast-in-place pile, the front and rear column pre-embedded sleeves 2 are first pre-embedded into the pile foundation 1, forming an integral whole with the pile foundation 1 reinforcement cage and pouring the foundation concrete together; after the foundation concrete strength reaches the design expectation, the front and rear steel pipe columns 4 can be inserted into the foundation sleeves.
[0057] The front and rear column embedded sleeves 2 are connected by welding with first connecting angle steel 3; the front and rear steel pipe columns 4 are respectively connected to the front and rear column embedded sleeves 2 by nesting, and are connected by three locking bolts 10 and one through bolt 11.
[0058] The front and rear steel pipe columns 4 are connected by a second connecting angle steel 5 and fixed with bolts; the front and rear steel pipe columns 4 and the front and rear diagonal supports 7 are connected by column clamps 6 and fixed with bolts; the diagonal beam 8 is connected to the front and rear steel pipe columns 4 by a triangular connector and fixed with bolts; the diagonal beam 8 is directly connected to the front and rear diagonal supports 7 by bolts; the purlin 9 is connected to the diagonal beam 8 by an angle steel purlin bracket and fixed with bolts.
