Description

Technical Field

[0001] The utility model relates to the technical field of flexible photovoltaic brackets, and more specifically, to an unfolding structure of a flexible photovoltaic bracket. Background Art

[0002] With the advancement of technology, flexible photovoltaic brackets are now entering the photovoltaic power generation industry with more economical and practical advantages. Flexible photovoltaic brackets have the advantages of large span, high clearance, less piles, and can greatly reduce the construction cost of photovoltaic power stations, especially in valleys and hilly areas. They can save a lot of land. Flexible photovoltaic brackets are mainly composed of supporting columns, unfolding cross frames, and several flexible cables installed between the unfolding cross frames. The ends of the flexible cables are fastened and installed on several connecting plates in the cross frames. The flexible cables are distributed in unfolded intervals, and photovoltaic panels are arranged and installed between adjacent flexible cables. However, during the use of the unfolding structure of the existing flexible photovoltaic bracket, since the connecting plates are fixed in the unfolding cross frames by welding, the spacing between adjacent connecting plates cannot be adjusted according to the actual use scenario on site, and it is difficult to meet the photovoltaic installation requirements of different widths, resulting in poor applicability when used for photovoltaic installation. In view of this, we propose an unfolding structure of a flexible photovoltaic bracket. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 4 As shown, the utility model provides an expansion structure of a flexible photovoltaic bracket, including a supporting column 1, a U-shaped expansion cross frame 2 and a plurality of connecting plates 3. The U-shaped expansion cross frame 2 is fixedly installed on the upper end of the supporting column 1. The top of the U-shaped expansion cross frame 2 is horizontally spaced apart with a plurality of longitudinal openings 201. The connecting plates 3 pass through the longitudinal openings 201 and penetrate the top of the U-shaped expansion cross frame 2. The side surface of the connecting plate 3 contacts the inner side surface of the U-shaped expansion cross frame 2, and the bottom surface of the connecting plate 3 contacts the inner bottom surface of the U-shaped expansion cross frame 2, so as to facilitate the rapid positioning of the connecting plate 3 on the U-shaped expansion cross frame 2. A limiting assembly 4 is arranged on the outer side of the U-shaped unfolding horizontal frame 2, and the limiting assembly 4 includes a limiting horizontal rod 401 and a limiting longitudinal rod 402. The limiting longitudinal rod 402 is fixedly connected to one end of the limiting horizontal rod 401. A horizontal opening 301 is provided on the side of the connecting plate 3 located above the U-shaped unfolding horizontal frame 2. The limiting horizontal rod 401 passes through the horizontal opening 301 and penetrates the side of the connecting plate 3. A fastening bolt 5 is threadedly connected between the U-shaped unfolding horizontal frame 2 and the limiting longitudinal rod 402, and the limiting longitudinal rod 402 can be fastened and installed, so that each connecting plate 3 on the U-shaped unfolding horizontal frame 2 can be synchronously limited and locked.

[0023] Among them, a plurality of flexible suspension cable mounting holes 302 are spaced apart on the side of the connecting plate 3 at the inner position of the U-shaped unfolding cross frame 2. The flexible suspension cable mounting holes 302 are spaced apart longitudinally, so that the ends of the flexible suspension cables can be mounted on the connecting plate 3.

[0024] There are two fastening bolts 5, which are longitudinally symmetrically arranged on the side of the U-shaped unfolded horizontal frame 2, so as to ensure the stability of the fastening installation of the limiting longitudinal rod 402. A countersunk groove 403 is provided on the side of the limiting longitudinal rod 402 at the corresponding position of the fastening bolt 5, and the end cap of the fastening bolt 5 is located in the countersunk groove 403, so that the end cap of the fastening bolt 5 can be hidden, thereby ensuring the overall appearance effect.

[0025] The bottom end of the support column 1 is fixedly connected to the base 6, and mounting holes 7 are provided at each corner of the surface of the base 6, so that the support column 1 can be positioned and installed. Two upper reinforcing diagonal bars 101 are symmetrically fixedly connected between the support column 1 and the U-shaped expansion horizontal frame 2 to improve the structural strength of the connection between the support column 1 and the U-shaped expansion horizontal frame 2, and two lower reinforcing diagonal bars 102 are symmetrically fixedly connected between the support column 1 and the base 6 to improve the structural strength of the connection between the support column 1 and the base 6.

[0026] The working principle and use process of this utility model:

[0027] When it is necessary to install the connecting plate 3 on the U-shaped horizontal frame 2, the connecting plate 3 is passed through the longitudinal opening 201 and penetrated through the top of the U-shaped horizontal frame 2, so that the side of the connecting plate 3 contacts the inner side of the U-shaped horizontal frame 2, and the bottom of the connecting plate 3 contacts the inner bottom of the U-shaped horizontal frame 2. The limiting cross bar 401 is passed through the horizontal opening 301 and penetrated through the side of the connecting plate 3, and the U-shaped horizontal frame 2 is fastened and connected with the limiting longitudinal bar 402 using the fastening bolts 5, so that each connecting plate 3 on the U-shaped horizontal frame 2 is uniformly connected. The step limit locking process is performed. When it is necessary to remove the connecting plate 3 on the U-shaped unfolding cross frame 2, loosen the fastening bolts 5 to make it separate from the U-shaped unfolding cross frame 2, pull the limit cross bar 401 out of the transverse opening 301 on the connecting plate 3, and take out the connecting plate 3 upward along the longitudinal opening 201 on the U-shaped unfolding cross frame 2, so that the connecting plate 3 can be easily disassembled, taken out and synchronously limit locked on the U-shaped unfolding cross frame 2, so that the spacing between adjacent connecting plates 3 can be adjusted according to the actual use scenario on site, so as to meet the photovoltaic installation requirements of different widths.
