Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic bracket design, in particular to a cable truss flexible photovoltaic bracket. Background Art

[0002] The cable truss flexible photovoltaic support is a new type of flexible support system for supporting photovoltaic modules. It mainly uses steel strands or steel wire ropes as the main supporting structure. It is tightened by inclined cables to resist the horizontal tension of the module cables, and the module angle is adjusted by high and low columns. During installation, prestressed steel wire ropes will be tensioned between the fixed points at both ends of the flexible photovoltaic support. The fixed points use rigid structures and outer inclined steel strands to provide support reaction forces. Independent foundations are provided under the steel columns at both ends of the support, and inclined steel strands are provided on the outside of the end steel columns. Under the steel strands is a counterweight-type independent foundation. This structure enables the steel wire rope system above the flexible support to generate an inward horizontal tension on the top of the end column, and the horizontal tension provided by the inclined steel strands at the top of the column can balance the horizontal tension of the steel wire rope.

[0003] The applicant has found through investigation that the existing counterweight structures connected to the bottom of the outer inclined steel strands are all independent, that is, the steel strands are straightened by a separate counterweight block to make them have good strength. However, this has the disadvantage that the independent counterweight blocks are not connected to each other and are independent of each other, resulting in their strength not being guaranteed in stormy weather. Once a counterweight block moves or loosens and affects a steel strand, the stability of the bracket may be affected, and the strength of the inclined steel strands cannot be completely guaranteed. The integral counterweight block, although all the outer inclined steel strands are connected by a counterweight block, is only applicable to brackets of different specifications and lengths. Moreover, if a single counterweight block is damaged somewhere, it needs to be replaced as a whole, which is very wasteful.

[0004] Therefore, in response to the above-mentioned deficiencies, the applicant proposes a cable truss flexible photovoltaic support to solve the problem. Utility Model Content

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] Embodiment 1, by Figure 1-Figure 6 The utility model includes a bracket body 1, a supporting strand 11 is provided on one side of the bracket body 1, and an oblique strand 12 is provided on the other side of the bracket body 1, and is characterized in that: the oblique strand 12 on one side of the bracket body 1 is installed on the counterweight assembly 2 through a connecting assembly 3, and the counterweight assembly 2 includes a counterweight block 21 spliced ​​together, and an insert block 24 and a slot are respectively provided on both sides of the counterweight block 21 located in the middle, and only one side of the two counterweight blocks 21 located on the side is provided with an insert block 24 or a slot, and the other sides of the counterweight blocks 21 on the two sides are fixed with a positioning plate 22, and a reinforcing steel bar 23 is installed on the positioning plate 22, and the bottom surface of the counterweight block 21 with a slot is provided with a screw hole passing through the slot, and after the insert block 24 is inserted into the slot, the bottom screw hole thereof corresponds to the position of the screw hole of the counterweight block 21, and a U-shaped clamping block 25 is installed on the counterweight block 21, and the U-shaped clamping block 25 is located at the splicing position of the two counterweight blocks 21, and assembly bolt holes are provided on both sides.

[0026] The specific operation is as follows: by designing the counterweight assembly 2, during assembly, the two bracket bodies 1 are installed at a distance so that the inclined stranded wire 12 is in a tensioned state, and then a relative number of counterweight blocks 21 are selected according to the needs, and the plug block 24 is inserted into the slot, and then the plug block 24 is fixed through the screw from the bottom of the slot to complete the assembly of the counterweight block 21. Then, the counterweight block 21 is placed in a suitable position, and the reinforcing steel bar 23 is rotated through the positioning plate 22 and inserted into the preset threaded hole on the ground. The ring plate on the reinforcing steel bar 23 is pressed tightly against the positioning plate 22, and the lower end is designed with an external thread, so that both ends are very firm, and finally the U-shaped block 25 is placed The two counterweight blocks 21 are engaged at the joint, and then the U-shaped block 25 is connected to the ground with screws to make the middle very firm. Finally, the inclined stranded wire 12 is installed on each counterweight block 21 through the connecting component 3. In this way, the detachable splicing design makes the overall design integrated. Even if a single U-shaped block 25 or a reinforcing steel bar 23 is loose, it will not affect the overall strength too much, avoiding the influence of a single looseness on the bracket strength.

In some areas with extreme weather, such as coastal cities with typhoons, the reinforced connecting block 26 can be welded on the U-shaped block 25. The reinforced connecting block 26 is connected to the counterweight block 21 by screws, which can further improve the overall strength of the counterweight assembly 2 and reduce safety hazards.

[0029] Embodiment 2, by Figure 1 as well as Figure 7-Figure 8 It is given that, different from the first embodiment, the connecting assembly 3 includes a steel ring 32 fixed to one end of the inclined stranded wire 12, the steel ring 32 is fixed to one side of the pressure block 31 and is an integrated design, the pressure block 31 is pressed on the top of the counterweight block 21, and passes through the anchor rod 27 fixed on the top of the counterweight block 21, and the anchor rod 27 is threaded with a nut 33, and four integrated positioning blocks 35 are fixed to the bottom of the pressure block 31, the positioning blocks 35 are inserted into the corresponding recesses on the top of the counterweight block 21, and the anchor rod 27 is also threaded with a pressing sleeve 34, which is cylindrical in design and the bottom surface is tightly pressed against the nut 33.

[0030] The specific operation is as follows. Through the design of the connecting component 3, when the inclined stranded wire 12 is connected to the counterweight block 21, the inclined stranded wire 12 is pulled in through the steel ring 32 and the pressure block 31 is sleeved on the outside of the anchor rod 27. After the pressure block 31 fits the surface of the counterweight block 21, the inclined stranded wire 12 is in a straightened state. Then, the nut 33 is put on to complete the fixation. The nut 33 can then be put on to further enhance the stability in the up and down directions, and the positioning block 35 enhances the stability of the pressure block 31 in the horizontal direction. This makes the inclined stranded wire 12 very stable and easy to disassemble.
