Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a high-efficiency corrosion-resistant photovoltaic spiral ground pile with a flange. Background Technology

[0002] In current photovoltaic power plant construction, ground piles, as key foundation components supporting photovoltaic modules, directly affect the safety and lifespan of the entire photovoltaic system. A significant problem with existing ground pile technology is the lack of effective reinforcement components. This makes the ground piles highly susceptible to toppling under various complex working conditions, severely impacting the normal operation of the photovoltaic power plant. From a structural design perspective, existing ground piles are mostly simple single-pile structures, relying solely on the depth of the pile's insertion into the ground and friction with the soil for stability. This design might barely meet support requirements in ordinary environments with good geological conditions and no extreme weather. However, its stability is severely challenged when encountering severe natural conditions such as strong winds, heavy rains, and earthquakes. To address these technical problems, a high-efficiency, corrosion-resistant photovoltaic helical ground pile with a flange is proposed. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency, corrosion-resistant photovoltaic spiral ground pile with a flange.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-efficiency corrosion-resistant photovoltaic spiral ground pile with a flange includes a ground pile body, a flange, bolts and nuts. The ground pile body is threaded, and four mounting blocks are provided on the outside of the ground pile body. Each mounting block has a movable groove, and a movable frame is provided in the movable groove. A reinforcing rod is installed at the bottom of the movable frame. An upper top groove is provided on the upper end face of the movable frame. A positioning block is provided in the upper top groove through an upper top mechanism. Each mounting block has three positioning holes.

[0006] Preferably, the upper lifting mechanism includes a spring disposed in the upper lifting groove, and the two ends of the spring are respectively connected to the outer wall of the positioning block and the inner wall of the upper lifting groove.

[0007] Preferably, all four mounting blocks are arc-shaped, and the four mounting blocks are combined together to form a ring.

[0008] Preferably, the vertical cross-sectional view of the movable frame is L-shaped, and the vertical cross-sectional view of the movable groove is also L-shaped.

[0009] Preferably, each mounting block is provided with a disassembly groove corresponding to the bolt, and each mounting block has a limiting groove at the bottom corresponding to the nut.

[0010] Preferably, the top view of the disassembly groove is U-shaped, and the bottom view of the limiting groove is a regular hexagon.

[0011] The beneficial effects of this utility model are:

[0012] 1. Through the cooperation of bolts, nuts, flanges, and mounting blocks, the mounting blocks cannot move vertically or detach horizontally from the main body of the ground pile, forming a stable ring structure that can provide solid support for photovoltaic brackets and modules.

[0013] 2. The position of the movable frame in the movable slot can be flexibly adjusted by changing the positioning holes of the positioning block, thereby changing the position of the reinforcing rod to adapt to different ground conditions and improve the adaptability of the ground pile to complex ground environments.

[0014] 3. After pressing the positioning block to compress the spring and completely separate it from the positioning hole, the movable frame can be directly pulled out, making it easy to disassemble the reinforcing rod and allowing for operation when not in use or when cleaning and maintenance are required.

[0015] 4. The top view of the disassembly slot is U-shaped, which facilitates the horizontal or vertical movement of the bolt shank for installation and disassembly; the bottom view of the limiting slot is hexagonal and the same size as the nut, which ensures that the nut can only be disassembled by descending vertically, thus ensuring the reliability and stability of the connection.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4The high-efficiency corrosion-resistant photovoltaic spiral ground pile with flange includes a ground pile body 1, a flange 3, bolts 4 and nuts 8. The flange 3 has mounting holes corresponding to the bolts 4. The ground pile body 1 has threads 2. The ground pile body 1 has four mounting blocks 5 on its exterior. Each mounting block 5 has a movable groove 11. The movable groove 11 contains a movable frame 6. The bottom of the movable frame 6 is equipped with a reinforcing rod 7. The upper end face of the movable frame 6 has an upper top groove 12. The upper top groove 12 contains a positioning block 13 through an upper top mechanism. Each mounting block 5 has three positioning holes 15.

[0023] The upper lifting mechanism includes a spring 14 disposed in the upper lifting groove 12, with both ends of the spring 14 connected to the outer wall of the positioning block 13 and the inner wall of the upper lifting groove 12, respectively. The elastic potential energy provided by the spring 14 enables the positioning block 13 to be lifted, partially pushing it into the positioning hole 15. At this time, the movable frame 6 will be fixed in the position within the movable groove 11 and will not move or change position within the movable groove 11.

[0024] All four mounting blocks 5 are arc-shaped, and when combined, they form a ring. As shown in the figure, when the four mounting blocks 5 are combined, they are located outside the main body 1 of the ground pile.

[0025] The vertical cross-section of the movable frame 6 is L-shaped, and the vertical cross-section of the movable groove 11 is also L-shaped. Because it is L-shaped, the movable frame 6 has a limiting effect when it is in the movable groove 11, and can only move out of the two openings of the movable groove 11, and cannot be directly separated from the movable groove 11.

[0026] Each mounting block 5 has a disassembly groove 9 corresponding to the bolt 4, and each mounting block 5 has a limiting groove 10 corresponding to the nut 8 at its bottom. The bolt 4 passes through the mounting hole on the flange 3 and is located below the flange 3. When the mounting blocks 5 are arranged in a ring shape, they are close to and in contact with the outer wall of the pile body 1. At this time, the bolt 4 is in the disassembly groove 9 and the end is in the limiting groove 10. When the nut 8 is in the limiting groove 10 and threadedly connected to the bolt 4, the mounting block 5 cannot move vertically on the pile body 1, nor can it move horizontally to detach from the pile body 1. The whole is a stable ring shape.

[0027] The top view of the disassembly slot 9 is U-shaped. This U-shaped design allows the bolt 4's shank to move horizontally or vertically to be installed and detached from the disassembly slot 9. The bottom view of the limiting slot 10 is a regular hexagon. Because it is a regular hexagon and the same size as the nut 8, the nut 8, located within the limiting slot 10, can only detach from it by descending vertically.

[0028] All of the above components are coated with a fluorocarbon coating. The fluorocarbon bonds in the coating have extremely high bond energy and are chemically very stable. The fluorocarbon coating forms a strong, smooth protective film on the surface of the components, effectively blocking the corrosion of the substrate by ultraviolet rays, oxygen, water, etc.

[0029] Components not specifically described in this utility model are all standard parts and can be purchased from the market. The specific connection methods of each component adopt mature methods in the prior art, and will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0030] In use, the photovoltaic bracket is positioned above the flange 3 and has mounting holes identical to those on the flange 3. Four mounting blocks 5 are located on the outer wall of the ground pile body 1 and close to forming a ring. Nuts 8 are positioned within the limiting groove 10. Bolts 4 pass through the mounting holes on the photovoltaic bracket and flange 3, and through the disassembly groove 9, also positioned within the limiting groove 10, and are threadedly connected to the nuts 8. Therefore, the four mounting blocks 5 cannot move vertically on the ground pile body 1, nor can they move to separate.

[0031] The main body of the ground pile 1 and the four reinforcing rods 7 are inserted into the ground to provide stable support for the photovoltaic bracket and photovoltaic modules.

[0032] In this solution, by changing the positioning hole 15 of the positioning block 13, the position of the movable frame 6 in the movable slot 11 can be changed, and the position of the reinforcing rod 7 on the movable frame 6 can be changed. For example, if the original four reinforcing rods 7 are evenly distributed around the circumference, but there are some areas on the ground where the reinforcing rods 7 cannot be inserted, the position of the reinforcing rods 7 that cannot be inserted into the ground can be changed.

[0033] In this solution, after pressing the positioning block 13 to compress the spring 14 and enter the upper groove 12, and completely disengage from the positioning hole 15, the movable frame 6 loses its limit and can be directly pulled out of the movable groove 11 to complete the disassembly of the reinforcing rod 7. It can be easily disassembled when it is not in use or needs cleaning and maintenance.

[0034] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
