Description

Technical Field

[0001] The utility model relates to the technical field of flexible photovoltaic brackets, and specifically refers to an A-shaped tube truss center column structure of a flexible photovoltaic bracket. Background Art

[0002] There are two common forms of center columns for existing mountain flexible photovoltaic supports: one is a square (round) steel tube center column hinged at the bottom, and the other is a steel section center column rigidly connected at the bottom. Both center columns have their own advantages and disadvantages. For example, the advantage of the square (round) steel tube center column is that it uses materials economically, but its disadvantage is that it is hinged at the bottom and has a small bearing capacity, so it is not suitable for mountainous areas with undulating terrain or flexible supports with a large single span. Another example is that the steel section center column has an advantage in that it has a strong bearing capacity. Although it can be used for large-span flexible supports in undulating mountains, the column has a larger cross-section, and the force transmitted to the foundation is larger, which places higher requirements on the foundation. Overall, it is not very economical. In order to overcome the shortcomings of the above two center columns, the present application provides an A-shaped tube truss center column structure for a flexible photovoltaic support. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a flexible photovoltaic bracket A-shaped tube truss middle column structure which can not only provide the load-bearing capacity of the middle column structure, but also save material consumption and reduce the force transmitted to the foundation. It can be used in flexible photovoltaic bracket scenarios with undulating terrain and large spans.

[0004] The technical solution adopted by the utility model is as follows: the utility model is a flexible photovoltaic support A-shaped tube truss center column structure, which is composed of a plurality of groups of support units, wherein the plurality of groups of support units are arranged in sequence along the longitudinal direction, and the plurality of groups of support units are connected by component locks, wherein the support units include an A-shaped tube truss center column structure and an inter-column diagonal brace, wherein the A-shaped tube truss center column structure is provided with a plurality of groups, wherein the plurality of groups of A-shaped tube truss center column structures are arranged in sequence along the transverse direction, and the inter-column diagonal brace is provided between two transversely adjacent groups of A-shaped tube truss center column structures, and the A-shaped tube truss center column structure includes a concrete foundation and a center column component, wherein the concrete foundation is provided with two groups, and the center column component is provided between the two groups of concrete foundations. The inter-column diagonal brace is arranged between two laterally adjacent groups of middle column components, and the middle column component comprises a bottom column plate, an oblique upright rod and a support beam, the bottom column plate is provided with two groups, and the two groups of the bottom column plates are respectively arranged on two groups of concrete foundations, the oblique upright rods are provided with two groups, and the two groups of the oblique upright rods are respectively hinged on the two groups of bottom column plates, an upper cross bar and a lower cross bar are connected between the two groups of the oblique upright rods, the upper cross bar is located above the lower cross bar, the support beam is arranged on the top of the two groups of oblique upright rods, a support rod is connected between the support beam and the upper cross bar, and the support rod is symmetrically provided with two groups, a U-shaped pad is provided on the support beam, a rope clamp is provided on the U-shaped pad, and the component lock is locked to the U-shaped pad by the rope clamp.

[0005] Furthermore, the concrete foundation is pre-embedded with embedded anchor bolts, the bottom column plate is provided with through holes, the embedded anchor bolts are inserted into the through holes, the embedded anchor bolts are threadedly connected with anchor nuts, and the bottom column plate is fixed to the concrete foundation by the embedded anchor bolts and the anchor nuts.

[0006] Furthermore, the inter-column diagonal brace includes an upper diagonal brace rod and a lower diagonal brace rod, the upper cross bar is provided with an upper ear plate, the lower cross bar is provided with a lower ear plate, the two ends of the upper diagonal brace rod are respectively arranged between two laterally adjacent groups of upper ear plates, and the two ends of the lower diagonal brace rod are respectively arranged between laterally adjacent upper ear plates and lower ear plates.

[0007] Furthermore, the upper diagonal brace rod and the upper ear plate, the upper ear plate and the lower diagonal brace rod, and the lower ear plate and the lower diagonal brace rod are all fixed by diagonal brace bolts.

[0008] Furthermore, the base column plate and the oblique upright rod, the oblique upright rod and the support beam, the support beam and the U-shaped pad, the U-shaped pad and the rope clamp, the oblique upright rod and the upper cross bar, the oblique upright rod and the lower cross bar, the support rod and the support beam, and the support rod and the upper cross bar are all connected by welding.

[0009] Furthermore, the oblique uprights, support beams, upper cross bars, lower cross bars, support bars, upper oblique braces and lower oblique braces are all steel pipe structures.

[0010] The beneficial effects achieved by the utility model using the above structure are as follows:

[0011] This scheme adopts A-shaped tube truss center column structure, which is a stable structural system. The inclined rod is hinged on the bottom column plate, which does not transmit bending moment and can reduce the effect of the center column component on the concrete foundation. Because the steel pipe is a two-force rod and only bears tension and pressure, it can give full play to the stress characteristics of steel, and the stress is more reasonable, which improves the reliability and safety of the bracket. At the same time, it can reduce the material consumption and improve the economy.

[0012] In this solution, there are two fulcrums between the bottom of the central column component and the concrete foundation. A stable triangular structure is formed between the central column component and the two sets of concrete foundations, providing greater rigidity within the truss plane, greatly improving the supporting force of the central column, and a stable triangular structure is formed between the supporting beam and the two sets of supporting rods, which makes the central column structure more stable, providing effective technical support for large-span flexible photovoltaic brackets and complex mountains with ups and downs, and the application scenarios are broader.

[0013] This solution locks the steel strands on the U-shaped pad by means of rope clamps. Since the supporting surface of the U-shaped pad for the steel strands is arc-shaped, the friction between the steel strands and the U-shaped pad at the fulcrum can be effectively reduced, the loss of pre-tension of the steel strands can be reduced, and the damage of the steel strands at the fulcrum can be reduced, thereby improving the durability of the steel strands. At the same time, it provides strong conditions for the small-angle bending of the steel strands at the fulcrum, and provides reliable technical guarantees for the laying of supports in undulating mountains.

[0014] This solution connects several groups of A-shaped tube truss center column structures horizontally into a whole through inter-column diagonal braces, and forms a stable triangular structure with the center column component through two upper and lower diagonal braces set at different angles, so that the entire flexible photovoltaic bracket also forms a stable structural system in the horizontal direction, further enhancing the stability and safety of the flexible photovoltaic bracket.
