Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, in particular to an adjustable photovoltaic bracket without a welding part structure. Background Art

[0002] Photovoltaic adjustable bracket is a device used to fix and adjust the angle of photovoltaic panels to adapt to the sunshine conditions in different seasons and different geographical locations, thereby improving the efficiency of photovoltaic power generation. Photovoltaic adjustable bracket with no welded parts structure means that no welding technology is used in the production process, but other connection methods (such as bolt connection, buckle, etc.) are used to ensure the stability and durability of the structure.

[0003] In actual use, the high temperature during the welding process may affect the microstructure of the material, especially in the heat-affected zone, which may cause local hardening or softening of the material. Fatigue cracks may occur in welded parts under long-term cyclic loads, especially at welded joints. The welding quality is affected by many factors, including operator skills, welding parameters, etc., which may lead to unstable quality of welded parts. If cracks or breaks occur in welded parts, repair may be more complicated and expensive than non-welded parts. Compared with non-welded lightweight designs, welded parts may be heavier, which not only affects transportation and installation, but may also affect the response of the entire structure to wind loads. If there are defects in the welded parts, such as microcracks or incomplete welding, they may be more susceptible to corrosion and environmental impacts. Utility Model Content

[0004] The utility model aims to provide an adjustable photovoltaic bracket without a welded structure.

Second bolts 7 penetrate through both the left and right sides of the second fixing block 6, enabling the second fixing block 6 to be fixed and its position adjusted through the bolts 7. A first nut 9 is threadedly connected to the outer ring of the second bolt 7. The nut 9 is used to fasten the bolt 7 to ensure the stability of the structure. A third fixing block 8 is rotatably connected to the outer ring of the second bolt 7. The third fixing block 8 is connected to the second fixing block 6 through the bolt 7 and can be rotated and adjusted within a certain range. Fixed columns are fixedly connected to both inner sides of the third fixing block 8. The fixed columns play a supporting role to maintain the verticality and stability of the structure. A fourth fixing block 10 is rotatably connected to the outer ring of the fixed column. The fourth fixing block 10 can move up and down along the fixed column to meet the adjustment requirements of different angles. Third bolts 11 penetrate through both the left and right sides of the second fixing block 6. The third bolts 11 are similar to the second bolts 7 and are used to fix and adjust the position of the second fixing block 6. A second nut 12 is threadedly connected to the outer ring of the third bolt 11. One end of the second nut 12 abuts against the inside of the first fixing block 2. The position of the first fixing block 2 can be finely adjusted through the nut 12. A seventh fixing block 18 is fixedly connected to the top end of the bottom plate 1. The seventh fixing block 18 provides support for the rotating column 19, enabling the rotating column 19 to rotate. Rotating columns 19 are fixedly connected to both inner sides of the seventh fixing block 18. A hydraulic pump 13 is rotatably connected to the outer ring of the rotating column 19.

Pass the second bolt 7 through the left and right sides of the second fixing block 6, and threadedly connect the first nut 9 to its outer ring to fasten the second fixing block 6. Rotationally connect the third fixing block 8 to the outer ring of the second bolt 7 to ensure that the third fixing block 8 can be rotated and adjusted within a certain range. Install the fixing columns on both sides inside the third fixing block 8, and rotationally connect the outer ring of the fixing columns to the fourth fixing block 10 so that the fourth fixing block 10 can move up and down along the fixing columns. Pass the third bolt 11 through the left and right sides of the second fixing block 6 and fasten it with the second nut 12. One end of the second nut 12 should abut against the inside of the first fixing block 2 to finely adjust the position of the first fixing block 2.
