Description

Technical Field

[0001] The utility model relates to the field of photovoltaic brackets, in particular to a tracking photovoltaic bracket adaptable to complex terrains. Background Art

[0002] The existing mainstream photovoltaic brackets in China include fixed photovoltaic brackets, flexible photovoltaic brackets, and tracking photovoltaic brackets. Among them, under the same conditions, the tracking photovoltaic bracket has the highest power generation, but the tracking photovoltaic bracket has great limitations and its terrain adaptability is average. The main design purposes of the pile caps and bearings of domestic tracking photovoltaic brackets are for the connection and rotation of photovoltaic brackets, and little consideration is given to their actual installation environment. This has led to a great limitation of the terrain for many tracking photovoltaic bracket products developed by companies in the market. However, as the domestic market becomes more and more saturated, the plots available for building photovoltaic power stations have decreased significantly, or rather, the flat and high-quality plots are getting fewer and fewer, resulting in an increasing requirement for the terrain adaptability of tracking photovoltaic brackets. If customers want to obtain the maximum power generation, they must install tracking photovoltaic brackets. However, if the on-site terrain environment is complex and the slope is large, it is difficult for tracking photovoltaic brackets to adapt. If fixed photovoltaic brackets or flexible photovoltaic brackets are installed, the maximum power generation demand of the power station cannot be met.

[0003] Therefore, how to develop a tracking photovoltaic bracket adaptable to complex terrains has become an urgent problem to be solved by those skilled in the art. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies existing in the prior art and provide a tracking photovoltaic bracket adaptable to complex terrains, which has a degree of freedom far greater than that of existing conventional transmission mechanisms, thereby enabling the tracking photovoltaic bracket to adapt to complex terrains. In addition, through structural optimization, this patent has the advantages of light weight, easy disassembly, assembly, and maintenance, and has a lower failure rate compared with traditional photovoltaic tracking brackets, and has great promotion value.

A plurality of positioning through holes are formed on the adjusting column and the fixed column, and the adjusting column and the fixed column are fixedly connected through a plurality of locking bolts adapted to the positioning through holes. The upper end of the adjusting column is fixedly connected to the U-shaped connecting portion.

[0011] According to the above technical solution, preferably, the cross sections of the fixed column and the adjusting column are both reduced-opening trough-shaped cross sections. An adjusting groove for accommodating the adjusting column is provided inside the fixed column, and the adjusting column is slidably connected to the adjusting groove of the fixed column.

[0024] As shown in the figure, the utility model provides a tracking photovoltaic support adapted to complex terrains, which includes a column mechanism 1, a transmission mechanism 2 and a support mechanism 3. The lower end of the column mechanism 1 is fixedly connected to the foundation 4. The transmission mechanism 2 is connected to the upper end of the column mechanism 1, and the transmission mechanism 2 is rotatably connected to the support mechanism 3. Among them, the transmission mechanism 2 includes a lower pile cap assembly 5, an upper pile cap assembly 6 and two sets of hemispherical bearings 7 that are symmetrically arranged up and down. The lower pile cap assembly 5 is fixedly connected to the upper end of the column mechanism 1. A rectangular card slot 9 adapted to the torque rod 8 of the support mechanism 3 is provided in the middle of the two sets of hemispherical bearings 7. Spherical card slots 10 adapted to the hemispherical bearings 7 are provided inside the lower pile cap assembly 5 and the upper pile cap assembly 6. The lower pile cap assembly 5 and the upper pile cap assembly 6 cooperate to clamp and limit the two sets of hemispherical bearings 7. The lower pile cap assembly 5 includes a U-shaped connecting part 11 and a lower hemispherical pile cap 12. The U-shaped connecting part 11 includes two sets of vertical plates 16 and a horizontal plate 17. The vertical plates 16 are perpendicularly and fixedly connected to both ends of the horizontal plate 17. The vertical plates 16 are fixedly connected to the upper end of the column mechanism 1 through multiple sets of locking bolts. The lower hemispherical pile cap 12 is coaxially and fixedly connected to the U-shaped connecting part 11. The upper pile cap assembly 6 includes an upper hemispherical pile cap. Two sets of symmetrically arranged connecting ears are provided at both ends of the lower hemispherical pile cap 12 and the upper hemispherical pile cap. Screw holes adapted to connecting bolts are provided on the connecting ears.

[0025] In this embodiment, spherical card slots 10 adapted to the hemispherical bearings 7 are provided inside the lower pile cap assembly 5 and the upper pile cap assembly 6. The lower pile cap assembly 5 and the upper pile cap assembly 6 cooperate to clamp and limit the two sets of hemispherical bearings 7. Therefore, the staff can adjust the hemispherical bearings 7 for locking the photovoltaic support to the set angles and positions according to the complex terrain conditions. Since the spherical card slots 10 are adapted to the hemispherical bearings 7, the hemispherical bearings 7 have degrees of freedom far greater than those of the existing conventional transmission mechanisms 2, thereby enabling the tracking photovoltaic support to adapt to complex terrains. In addition, through structural optimization, this patent has the advantages of light weight, easy disassembly, assembly and convenient maintenance. Moreover, even if geological collapse or settlement occurs during the later use of the photovoltaic tracking support, it can also achieve a certain degree of self-adjustment, and has the advantage of low failure rate compared with traditional photovoltaic tracking supports, and has great popularization value.

[0026] Optionally, in a possible implementation manner, the column mechanism 1 includes a fixed column 13 and an adjustment column 14 that are adjustably connected. The lower end of the fixed column 13 is fixedly connected to the foundation 4. The adjustment column 14 is slidably and adjustably connected to the fixed column 13. Multiple sets of positioning through holes are provided on the adjustment column 14 and the fixed column. The adjustment column 14 and the fixed column are fixedly connected through multiple sets of locking bolts adapted to the positioning through holes. The upper end of the adjustment column 14 is fixedly connected to the U-shaped connecting part 11, thereby facilitating the staff to quickly and stably adjust the height of the column mechanism 1 according to the complex terrain.

[0027] Optionally, in a possible implementation, the cross-sections of the fixed column 13 and the adjustment column 14 are both flared groove-shaped cross-sections. An adjustment groove 15 for accommodating the adjustment column 14 is provided in the fixed column 13, and the adjustment column 14 is slidably connected to the adjustment groove 15 of the fixed column 13. The flared groove-shaped cross-section not only improves the strength of itself, but also can effectively lock the adjustment column 14 in the fixed column 13.

[0028] Obviously, the above embodiments are only examples given for clear illustration, and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation manners here. The obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
