Detailed Description
The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the invention easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the invention.
Examples
Referring to fig. 2, the flexible photovoltaic bracket comprises terminal supporting members S1 at two ends and a middle supporting member S2 in the middle, wherein at least one group of steel stranded wires S4 is arranged between the terminal supporting member S1 and the middle supporting member S2 for installing and placing a photovoltaic module S3, and two sides of the terminal supporting member S1 are fixed by stay ropes.
The structure of the intermediate support is shown in fig. 3 and 4, and comprises a vertical column 1 and a diagonal brace 2 arranged on the vertical column 1. A channel for a steel strand S4 to pass through is arranged on the inclined strut 2, and the steel strand S4 can horizontally slide in the channel; and limiting blocks 3 are arranged on the steel strands S4 on two sides of the channel, and the maximum width of each limiting block 3 is greater than the opening of the channel and can block the channel.
Specifically, in this embodiment, two ends of the diagonal brace 2 are provided with hanging rings 4, and an inner hole of each hanging ring 4 is the channel. The hanging ring 4 is fixed on the inclined support rod 2 in a bolt locking mode, and the installation convenience is improved. The inclined stay bar 2 is provided with a mounting position for placing a pin of the lifting ring 4, and the mounting position can be a mounting hole (the position of the lifting ring is fixed and can not be adjusted) matched with the pin of the lifting ring, and can also be a long-strip-shaped mounting groove (the position of the lifting ring is fixed and can be adjusted).
As in the prior art, the two ends of the diagonal brace 2 are respectively provided with a reinforcing rib 5, one end of each reinforcing rib 5 is connected with the upright post 1, the other end of each reinforcing rib is fixed on the diagonal brace 2, and the reinforcing ribs 5 and the diagonal brace 2 form a triangular structure.
In the actual use process, in order to avoid the rust-proof paint on the surface of the steel strand S4 from falling off due to long-term moving friction, the steel strand part between the two limiting blocks is additionally protected in the embodiment. As shown in fig. 5, a protective sleeve 6 is fixedly arranged on the stranded wire S4 between the two limiting blocks 3, and the protective sleeve 6 slides in the channel.
The above-mentioned selection of the protective sheath 6 is mainly based on two aspects, namely on the one hand on the material with a low coefficient of friction with the passage and on the other hand on the material with wear resistance.
The protective sleeve in the embodiment can be made of plastic or metal materials, a polytetrafluoroethylene coating is sprayed on the surface of the protective sleeve, and the clamping problem of the protective sleeve in the long-term friction process can be avoided by utilizing the characteristics of temperature resistance, ageing resistance and high lubrication of polytetrafluoroethylene. Of course, the protective sleeve can also be made of polytetrafluoroethylene material integrally.
