Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic bracket installation, in particular to a middle column installation structure of a flexible bracket for mountain photovoltaic power generation. Background Technique

[0002] Under the background of the global energy structure transformation, solar energy, as a clean and renewable energy form, is increasingly becoming the core force to promote green development. Mountainous areas, with their rich sunlight resources and vast unused land, have become important positions for the construction of photovoltaic power stations. The flexible photovoltaic bracket system can stably support photovoltaic panels. The flexible photovoltaic bracket system is a large-span multi-span structure, which uses prestressed steel wires to be tensioned between two fixed points at both ends, and the two fixed points at both ends adopt a rigid structure and the form of outer stay cables to provide support reaction force to adapt to situations such as mountain undulations. As an important part of the flexible bracket, the middle column not only bears the weight of the photovoltaic modules but also ensures the stability of the overall structure.

[0003] In the prior art, the connection between the middle column and the cross beam of the flexible bracket for mountain photovoltaic power generation is usually bolted. Although this connection method ensures the firmness of the connection to a certain extent, during long-term operation, due to the influence of external factors such as wind force and temperature change, the bolts are prone to vibration and impact, resulting in loosening, which leads to unstable connection, and further affects the stability and safety of the entire bracket system, and then affects the stability of the bracket and the power generation efficiency of the photovoltaic modules. Content of the Utility Model

[0004] The purpose of the utility model is to provide a middle column installation structure of a flexible bracket for mountain photovoltaic power generation, which solves the problem that bolts are prone to loosen due to environmental factors by setting limit blocks and vertical rods to limit the bolts.

Reserved holes are opened on the middle column body, and the number of the reserved holes is two. Vertical rods are slidably matched in both of the two reserved holes. The tops of the two vertical rods are connected with a cross bar. A positioning block is installed on the outer surface of the cross bar. Limit blocks are installed at both ends of the cross bar. Limit grooves are opened on both of the two limit blocks. A rectangular frame is installed inside the middle column body. A partition board is installed inside the rectangular frame. Through holes are opened on the rectangular frame, and the number of the through holes is two. Plug rods are slidably matched in both of the two through holes. Blocks are installed at one ends of the two plug rods. Springs are connected between the outer surfaces of the two blocks and the partition board. Jacks are opened at the bottoms of the vertical rods, and the plug rods are fitted in the jacks.

[0007] Furthermore, a cross beam body is installed at the top of the middle column body, and an anti-slip sleeve is arranged between the middle column body and the cross beam body.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , the present invention provides a technical solution: a central column installation structure for a flexible support of mountain photovoltaic power generation, including a central column body 1, a cross beam body 2 is installed on the top of the central column body 1, reinforcing ribs are installed on the cross beam body 2, and the number of the reinforcing ribs is two. The positioning block 6 is slidably matched between the two reinforcing ribs. By providing the two reinforcing ribs, the stability of the cross beam body 2 can be increased, and at the same time, it is convenient for the positioning block 6 to move and position the horizontal rod 4. An anti-slip sleeve 103 is arranged between the central column body 1 and the cross beam body 2. A bolt 201 is matched with the cross beam body 2, and a threaded hole 102 matched with the bolt 201 is opened on the central column body 1. The top of the bolt 201 is matched in the threaded hole 102. Reserved holes 101 are opened on the central column body 1, and the number of the reserved holes 101 is two. Vertical rods 3 are slidably matched in both of the two reserved holes 101. The tops of the two vertical rods 3 are connected with a horizontal rod 4. A positioning block 6 is installed on the outer surface of the horizontal rod 4. Limiting blocks 5 are installed at both ends of the horizontal rod 4. Limiting grooves are opened on both of the two limiting blocks 5. After the cross beam body 2 is installed on the central column body 1 through the bolt 201, at this time, the horizontal rod 4 is vertically moved downward, so that the positioning block 6 slides between the two reinforcing ribs, and the vertical rods 3 at both ends of the horizontal rod 4 respectively slide in the reserved holes 101. At this time, the two limiting blocks 5 are respectively matched with the tops of the corresponding bolts 201 to limit the bolts 201, preventing the bolts 201 from rotating, thereby significantly reducing the risk of the bolts 201 loosening.

[0023] A rectangular frame 7 is installed inside the column body 1. A partition plate 701 is installed inside the rectangular frame 7. Through holes are formed in the rectangular frame 7, and the number of the through holes is two. Plug rods 8 are slidably fitted in both of the two through holes. Blocks 9 are installed at one ends of the two plug rods 8. L-shaped rods 11 are installed on both of the two blocks 9. By means of the two L-shaped rods 11 arranged, the pulling of the block 9 can be facilitated, so that the limiting of the vertical rod 3 is convenient. Springs 10 are connected between the two blocks 9 and the outer surfaces of the partition plate 701. A jack 301 is formed at the bottom of the vertical rod 3, and the plug rod 8 is fitted in the jack 301. When the two vertical rods 3 respectively slide into the corresponding reserved holes 101, the two L-shaped rods 11 are pulled inwards to drive the block 9 to move and compress the spring 10. After the vertical rod 3 slides into the reserved hole 101, at this time, the two L-shaped rods 11 are released, and the spring 10 pushes the block 9 to enable the plug rod 8 to be connected into the jack 301 to limit and fix the vertical rod 3, preventing the vertical rod 3 from moving out of the reserved hole 101, and further enabling the limiting block 5 to stably limit the bolt 201.
