Description

Technical Field

[0001] The utility model relates to the field of floating photovoltaics on water surfaces, lakes, offshore and deep sea waters, and particularly relates to a profiled steel frame floating photovoltaic support system. Background Art

[0002] Photovoltaic power generation requires a large number of scattered components for assembly. However, water operations cannot carry out construction with a large working surface area. Each working surface requires the cooperation of ships, and a large number of scattered components bring difficulties to the anti-corrosion of floating photovoltaics. In order to reduce the number of working ships and improve construction efficiency, the water operations are transferred to the shore for completion. A profiled steel frame floating photovoltaic support system is designed, which can be quickly assembled on site, saving ships and reducing costs.

[0003] The publicly disclosed patent CN220964776U discloses a purlinless photovoltaic support system. In this photovoltaic support system, the photovoltaic panel is embedded in the photovoltaic panel frame, and the bottom of the photovoltaic panel frame is fixed on the photovoltaic panel support platform through point supports to achieve the rapid assembly of the photovoltaic support system. However, during the actual construction process of this photovoltaic support system, there are the following problems: there is not enough bolt installation space between the top of the point support and the photovoltaic panel frame, making it difficult to install and fix the bolts. It is necessary to complete the bolt connection first and then install the photovoltaic panel, resulting in two sea hoists, complex construction steps, high costs, and too long construction time for construction personnel at sea, with relatively high safety risks. In addition, hoisting the photovoltaic panel alone is also likely to cause damage to the photovoltaic panel. Based on this, it is necessary to further improve the structure of the existing photovoltaic support system to make it more convenient for actual floating photovoltaic construction applications.

Detailed implementation manners

[0025] The following further describes the present utility model in conjunction with the accompanying drawings and specific embodiments, but the following embodiments are by no means any limitation to the present utility model.

[0026] Embodiment 1

[0027] Refer to Figure 1 and Figure 2 The steel frame water photovoltaic support system includes a photovoltaic module 1, a steel frame 2 and a support structure 3 connected in sequence from top to bottom; wherein, the photovoltaic module 1 and the steel frame 2 are connected and fixed by a plurality of fixing buckles 4 evenly arranged in the circumferential direction, and the steel frame 2 and the support structure 3 are connected and fixed by a connecting component.

[0028] The photovoltaic module 1 is composed of multiple photovoltaic panels, and the photovoltaic panels are directly purchased from commercially available products. The number and specifications of the photovoltaic panels are determined according to the needs of photovoltaic power generation. In this embodiment, the photovoltaic module 1 is composed of eight commercially available photovoltaic panels, which are laid flat in two columns, with four in each column.

[0029] Refer to Figure 3 The steel frame 2 is formed by splicing a plurality of eye-shaped frames; specifically, each eye-shaped frame includes two long steel sections 5, two short steel sections 6, one connecting steel section 7 and four gusset plates 8; the two long steel sections 5 are arranged in parallel at intervals, the two short steel sections 6 are arranged between the two long steel sections 5 and are arranged in parallel at intervals, and are connected and fixed in sequence to form a rectangular frame; the connecting steel section 7 is vertically arranged between the two long steel sections 5, and its two ends are respectively fixed in the middle of the two long steel sections 5; the four gusset plates 8 are respectively fixed on the bottom surface of the rectangular frame, and a connecting hole is opened at the center of the plate surface of each gusset plate 8. A plurality of fixing buckles 4 are arranged on the top surface of each eye-shaped frame in the circumferential direction for assembling the photovoltaic module 1.

[0030] In this embodiment, the two long steel profiles 5 and the two short steel profiles 6 are both L-shaped steel profiles arranged in an inverted manner, and the connecting steel profile 7 is a T-shaped steel profile arranged in a positive direction. The connecting ends of adjacent long steel profiles 5 and short steel profiles 6 are welded and fixed, and both ends of the connecting steel profile 7 are welded and fixed to the two long steel profiles 5; the four gusset plates 8 are four right-angled triangular plates, which are welded and fixed to the bottom surface of the rectangular frame body in such a way that their right-angled vertices coincide with the four vertices of the rectangular frame body, so that the entire steel profile frame 2 is a photovoltaic support structure with a regular shape; twelve fixing buckles 4 are arranged circumferentially on each "day" shaped frame. Specifically, two fixing buckles 4 are evenly arranged on each long steel profile 5 and short steel profile 6 respectively, and two rows of fixing buckles 4 are arranged side by side on the top surface of the connecting steel profile 7, and two fixing buckles are arranged in each row; preferably, the positions of the two fixing buckles 4 on each steel profile divide the steel profile where they are located into three sections.

[0031] In the present utility model, the long steel profiles 5, the short steel profiles 6 and the connecting steel profiles 7 do not need to be prefabricated. Directly according to the size setting requirements of the steel profile frame 2, they are cut from commercially available and low-cost L-shaped steel profiles or T-shaped steel profiles, and then through simple welding, the steel profile frame 2 can be made on site, effectively reducing the material cost; on the other hand, by fixing the gusset plates 8 at the four corners of the bottom surface of the steel profile frame 2 made of L-shaped steel profiles or T-shaped steel profiles, it not only provides a connection position for the connection between the steel profile frame 2 and the support structure 3, and because there is a spacing distance between the gusset plate 8 and the top surface of the steel profile frame 2, and the photovoltaic module 1 is arranged above the steel profile frame 2 through the fixing buckle 4, there is sufficient installation space above the gusset plate 8, ensuring that the construction personnel can quickly and effortlessly connect and fix the steel profile frame 2 to the support structure 3 through the barge connection assembly on the sea.

[0032] See Figure 4 , the fixing buckle 4 includes a buckle 401 and a connecting bolt 402; wherein, the buckle 401 includes a first horizontal short plate, a second horizontal short plate and a third horizontal long plate that are vertically and spaced apart from top to bottom and fixed on the first vertical plate, and a second vertical plate is vertically fixed between the second horizontal short plate and the third horizontal long plate; wherein, the distance between the first horizontal short plate and the second horizontal short plate is adapted to the thickness of the commercially available photovoltaic panel, so that the two form a U-shaped clamp that can sandwich the upper and lower sides of the photovoltaic panel with the first vertical plate; an installation screw hole is opened on the third horizontal long plate; the connecting bolt 402 is inserted into the screw hole on the third horizontal long plate from bottom to top, and a gasket and a fastening nut are sequentially sleeved on the tail end of the connecting bolt 402; in actual application, the buckle 401 is vertically arranged at the designated position of the steel profile, and a steel profile through hole is opened on the steel profile at this position, so that the connecting bolt 402 is inserted into the steel profile through hole and the installation screw hole from bottom to top, and the fixing buckle 4 is fixed at the designated position of the steel profile by sequentially sleeving a gasket and a fastening nut on the tail end of the connecting bolt 402.

[0033] See Figure 1 andFigure 2 , the support structure 3 is an inverted trapezoidal platform structure composed of an upper platform layer, a connecting beam body, and a lower platform layer connected in sequence from top to bottom; wherein, both the upper platform layer and the lower platform layer are planar structures formed by connecting multiple connecting beams, and the connecting beam body is a vertical structure body with a planar or inclined top surface formed by connecting multiple connecting beams according to the sunlight irradiation conditions at the installation location of the photovoltaic support system; wherein, in order to ensure sufficient connection strength between the photovoltaic module 1 and the support structure 3, the connection nodes 301 between the multiple connecting beams of the upper platform layer can correspond to the four vertex positions of each H-shaped frame in the steel frame 2; so that each H-shaped frame is fixed above the support structure 3 through the connecting pieces arranged at the connection nodes 301; specifically, the support structure 3 includes but is not limited to a steel structure, a concrete structure, and a structural system formed by combining the two.

[0034] In this embodiment, since the steel frame 2 is formed by splicing four H-shaped frames, therefore, the upper platform layer of the support structure 3 is a cross-shaped frame body fixed by multiple connecting beams, and the size of the cross-shaped frame body is slightly larger than the size of the steel frame 2.

[0035] As a preferred technical solution of this embodiment, the connection nodes 301 between every two connecting beams on the support structure 3 are each made to form a strengthened structure at the connection point by increasing the diameter at the connection point (such as the diameter of the welding point at the connection point).

[0036] See Figures 5 to 7 , the connecting component includes a single-claw connecting claw 9, a double-claw 90° connecting claw 10, and a four-claw connecting claw 11, and the number of different types of connecting claws is related to the number and splicing method of the H-shaped frames; wherein,

[0037] The single-claw connecting claw 9 is used for connecting the H-shaped frames at the four vertex corners of the photovoltaic module 1 and the support structure 3; specifically, the adapter base of the single-claw connecting claw 9 is welded and fixed on the top of the corresponding connection node 301 on the support structure 3 in a manner perpendicular to the upper platform layer, so that the claw body of the single-claw connecting claw 9 is connected and fixed to the top of the adapter base in a manner parallel to the upper platform layer (as Figure 2 shown); the connecting bolt 12 on the single-claw end side of the single-claw connecting claw 9 is passed through and connected through the through holes on the gusset plate 8 at the vertex corner of the corresponding H-shaped frame, and is sequentially connected and fixed by sleeving washers and nuts, so that the connection node 301 of the support structure 3 is connected and fixed to the corresponding vertex corner end of the H-shaped frame through the single-claw connecting claw 9;

[0038] The double-claw 90° connecting claw 10 is used for connecting between two adjacent day-shaped frames and the support structure 3 at the four side positions of the photovoltaic module 1; specifically, the adapter base of the double-claw 90° connecting claw 10 is welded and fixed to the top of the corresponding connection node 301 on the support structure 3 in a manner perpendicular to the upper platform layer, so that the claw body of the double-claw 90° connecting claw 10 is connected and fixed to the top end of the adapter base in a manner parallel to the upper platform layer (as shown in Figure 2 ); the connecting bolts 12 at the two claw ends of the double-claw 90° connecting claw 10 are respectively inserted into the through holes of the gusset plates 8 at the top corners of the corresponding two adjacent day-shaped frames, and are sequentially connected and fixed to the gusset plates 8 by sleeving washers and nuts at the tails of the respective connecting bolts 12, so that the connection node 301 of the support structure 3 is simultaneously connected and fixed to the top corners of the two adjacent day-shaped frames through the single-claw connecting claw 9;

[0039] The four-claw connecting claw 11 is used for connecting between every four adjacent day-shaped frames and the support structure 3 at the middle position of the photovoltaic module 1; specifically, the adapter base of the four-claw connecting claw 11 is welded and fixed to the top of the corresponding connection node 301 on the support structure 3 in a manner perpendicular to the upper platform layer, so that the claw body of the four-claw connecting claw 11 is connected and fixed to the top end of the adapter base in a manner parallel to the upper platform layer (as shown in Figure 2 ); the connecting bolts 12 at the four claw ends of the four-claw connecting claw 11 are respectively inserted into the through holes of the gusset plates 8 at the top corners of the corresponding four adjacent day-shaped frames, and are sequentially connected and fixed to the gusset plates 8 by sleeving washers and nuts at the tails of the respective connecting bolts 12, so that the connection node 301 of the support structure 3 is simultaneously connected and fixed to the top corners of the four adjacent day-shaped frames through the single-claw connecting claw 9.

[0040] In the present utility model, each photovoltaic panel in the photovoltaic module 1 is suspended above the profiled steel frame 2 by using a plurality of fixing buckles 4 in a manner parallel to the top surface of the profiled steel frame 2 and with a gap from the profiled steel frame 2, leaving sufficient manual assembly space for the connection between the profiled steel frame 2 and the support structure 3; in the actual application of this profiled steel frame water-based photovoltaic support system, the photovoltaic module 1 for offshore construction is pre-assembled with the profiled steel frame 2 on land to form an assembled component. During the assembly process, the support structure 3 is pre-connected to the offshore photovoltaic installation pile foundation; then it is directly hoisted onto the support structure 3 that has been fixed offshore. By aligning and inserting the gusset plates 8 on the profiled steel frame 2 with the connecting bolts 12 on each connecting claw of the support structure 3, and then installing washers and nuts at the tails of the respective connecting bolts 12, the rapid docking construction of the photovoltaic module 1, the profiled steel frame 2 and the support structure 3 on the offshore pile body can be realized, greatly improving the offshore photovoltaic construction efficiency.
