Description

Technical Field

[0001] The invention relates to the technical field of offshore photovoltaic power generation, and in particular to a double-cable modular offshore photovoltaic support structure. Background Art

[0002] Photovoltaic power generation, as a renewable clean energy, has become the mainstream and reality of energy production and development. Among them, the multi-span single-cable photovoltaic support structure is a typical structure of offshore flexible photovoltaic support structure. It adopts a single-cable, modular structure, that is, photovoltaic module modules are placed between two cables, and two adjacent photovoltaic module modules share one cable; it adopts a pile-cable connection structure, the cable is directly connected to the pile, and one pile corresponds to one cable. This technology has the following defects:

[0003] (1) The traditional single-cable structure, that is, one pile corresponds to one cable. Because the construction sequence is to sink the pile first and then pull the cable, the position of the cable is determined by the position of the pile. However, due to the small error of the photovoltaic module module, the installation accuracy is required to be high, so the spacing accuracy of the cable is required to be high, that is, the pile sinking accuracy is required to be high. As a result, there are many auxiliary equipment and auxiliary processes during pile sinking, which leads to slow pile sinking construction speed and high cost.

[0004] (2) Two adjacent photovoltaic modules share a common cable and are connected to each other by bolts. The position of the later installed module is determined by the position of the earlier installed module. The positions of adjacent modules are strictly corresponding and the module installation accuracy is required to be high. As a result, there are many auxiliary equipment and auxiliary processes during module installation, which results in slow installation and high cost.

[0005] (3) Two adjacent PV modules share a cable. When the later module is installed, the earlier module is already fixed on the cable. This results in the cable already having a structure when the module is installed, and the module cannot slide on the cable. Therefore, the single cable structure cannot adapt to automatic sliding installation.

[0006] (4) The cables are directly connected to the piles, one cable for each pile, and the piles are sunk first before installing the crossbeam between the two piles. The crossbeam is connected to the piles by bolts, but the crossbeam is made on land, which requires high installation accuracy. This makes the installation of the crossbeam difficult, slow, and expensive. Summary of the invention

DETAILED DESCRIPTION

[0042] A four-span double-row double-cable modular offshore photovoltaic support structure is listed below, and the present invention is further described in conjunction with the accompanying drawings and embodiments, but it is not used as a basis for limiting the present invention.

[0043] like Figure 1-3 As shown, a double-cable modular offshore photovoltaic support structure is provided, in which an inserted crossbeam 3 is arranged between the pile tops of adjacent pile structures 4 in the transverse direction, and an insertion end 31 and a connection end 32 are respectively arranged at the head and tail ends of the inserted crossbeam 3, and adjacent inserted crossbeams 3 are connected head and tail at the pile top of the same pile structure 4, and the inserted end 31 is plugged into and matched with the hole on the pile top; the inserted end 31 and the connection end 32 in a single inserted crossbeam 3 are both provided with hanging points connected to the cable structure 2, and the hanging points in the inserted end 31 and the connection end 32 of the same pile top are spaced apart; the longitudinally adjacent inserted crossbeams 3 are connected by two cable structures 2 to form an independent installation space for photovoltaic component modules 5 between the longitudinally adjacent inserted crossbeams 3, and a pressure plate type block cable connection structure 6 connected to the cable structure 2 is arranged at the end of the photovoltaic component module 5 to form a sliding installation state or a fixed-point stable state of the photovoltaic component module 5 on the cable structure 2, and a rigid adjustable connecting rod 7 is arranged between the photovoltaic component modules 5 in adjacent installation spaces.

[0044] In this embodiment, four-span cable structures 2 are arranged longitudinally, two rows of cable structures 2 are arranged transversely, 7 photovoltaic template blocks 5 are arranged on each cable structure 2, and 4 photovoltaic panels are arranged on each photovoltaic template block 5. Among them, the pile structure 4 is arranged in 5 rows transversely and 3 rows longitudinally, with a total of 15 groups. The anchoring structure 1 is arranged on both sides of the double-cable modular offshore photovoltaic support structure longitudinally, with 3 groups each and located on the same straight line with the pile structure 4.

[0045] Thus, each photovoltaic assembly module 5 is independently placed on two cable structures 2, and laterally adjacent photovoltaic assembly modules 5 are respectively placed on two adjacent cable structures 2, so adjacent photovoltaic assembly modules 5 do not share the same cable structure 2. Seven groups of photovoltaic assembly modules 5 are connected on each cable structure 2 through a pressure plate type block cable connection structure 6. Four photovoltaic panels are installed on each group of photovoltaic assembly modules 5, and the distance between laterally adjacent photovoltaic assembly modules 5 is adjusted by two adjustable connecting rods 7. It should be noted that two adjacent photovoltaic assembly modules 5 do not share the cable structure 2, are not connected by bolts, but are connected by adjustable connecting rods 7, so the installation error of two adjacent photovoltaic assembly modules 5 can be adjusted by the adjustable connecting rods 7, thereby reducing the installation accuracy requirements of the photovoltaic assembly modules 5, facilitating the installation of the photovoltaic assembly modules 5, and speeding up the installation speed.

[0046] In this embodiment, two adjacent photovoltaic assembly modules 5 do not share the cable structure 2, and only one photovoltaic assembly module 5 is installed on one cable structure 2. There are no obstacles when the photovoltaic assembly module 5 is slidingly installed, thereby realizing automatic sliding installation of the photovoltaic assembly module 5.

[0047] like Figure 1-3 As shown, the anchor structure 1 is composed of an end foundation pile 11, a cap 12 and a lug plate 13. The end foundation pile 11 is a steel pipe inclined pile, which is used to bear the horizontal force and vertical force transmitted to the anchor structure 1 by the cable structure 2. The cap 12 is a steel structure fixed on the end foundation pile 11. The lug plate 13 is located above the cap 12 and is fixedly connected to the cap 12. There are holes on the lug plate 13, which can fix the cable structure 2 on the anchor structure 1.

[0048] like Figure 3-9 As shown, specifically, the inserted crossbeam 3 includes a frame-type crossbeam body 33 , and both ends of the crossbeam body 33 are respectively connected and fixed to the insertion end 31 and the connection end 32 ; a cable bridge beam 34 and an inverter bridge beam 35 are connected below the crossbeam body 33 .

[0049] In this embodiment, the crossbeam body 33 of the frame structure includes a crossbeam main material 331, a crossbeam horizontal rod 332 and a crossbeam diagonal rod 333. The crossbeam main material 331 is made of channel steel, and the crossbeam horizontal rod 332 and the crossbeam diagonal rod 333 are made of flat steel. There are two crossbeam main materials 331, and the notches are arranged facing each other. A beam horizontal rod 332 and 11 crossbeam diagonal rods 333 are arranged at the upper and lower ends, and the two ends are welded to the insertion end 31 and the connection end 32 respectively. Two cable bridge beams 34 are welded below the two ends of the crossbeam main body 33, and a cable bridge is arranged on it. An inverter bridge beam 35 is welded below the middle of the crossbeam main body 33, and an inverter is arranged on it. The cable bridge beam 34 and the inverter bridge beam 35 are both welded by angle steel. The inserted crossbeam 3 is fixed by welding in the factory and then constructed on site at sea.

[0050] The insertion end 31 includes an insertion rod 311 plugged into the hole on the pile top, and a first platform, in which a first through hole connected to the insertion rod 311 is provided; the connection end 32 includes a second platform, in which a second through hole matched with the insertion rod 311 is provided, so that the insertion end 31 on the same pile top is plugged into the connection end 32 through the insertion rod 311; at the same time, the height of the first platform is greater than the height of the second platform. In this embodiment, the insertion rod 311 is a cylindrical solid steel pipe with pointed ends, and its diameter is smaller than the inner diameter of the support pile 41.

[0051] Among them, a first main cable ear plate 315 is arranged on the first platform, and the first main cable ear plate 315 is welded to the crossbeam body 33. The hanging point of the cable structure 2 at the insertion end 31 is a first connecting hole arranged on the first main cable ear plate 315, and one is arranged on each side of the longitudinal direction through the first connecting hole to anchor the cable structure 2; a second main cable ear plate 322 is arranged on the second platform, and the second main cable ear plate 322 is welded to the crossbeam body 33. The hanging point of the cable structure 2 at the connection end 32 is a second connecting hole arranged on the second main cable ear plate 322, and one is arranged on each side of the longitudinal direction through the first connecting hole to anchor the cable structure 2; the first connecting hole is arranged flush with the second connecting hole.

[0052] In the present embodiment, the hanging point of the cable structure 2 is relatively arranged on the crossbeam body 33, that is, the position of the cable is determined when the inserted crossbeam 3 is manufactured, and is not dependent on the pile driving accuracy. When the inserted crossbeam 3 is manufactured separately, its accuracy can be maintained at a high level. Therefore, through this technology, the installation accuracy of the cable structure 2 is decoupled from the pile driving accuracy, and the cable structure 2 is installed with high accuracy while the pile driving accuracy requirement is very low, which facilitates the pile driving construction, speeds up the pile driving speed, and reduces the pile driving cost.

[0053] The first platform includes an upper end plate 312 and a lower end plate 314, and a reinforcing plate 313 is arranged between the upper end plate 312 and the lower end plate 314, and the first through hole penetrates both the upper end plate 312 and the lower end plate 314. The upper end plate 312 and the lower end plate 314 are rectangular steel plates, and the first through holes in the upper end plate 312 and the lower end plate 314 are used to place the insertion rod 311, and are connected by welding; four reinforcing plates 313 are arranged at equal angles along the circumference of the insertion rod 311 to strengthen the connection with the insertion rod 311. At the same time, a first connecting plate 316 is welded on the upper part of the upper end plate 312, and the upper part of the first connecting plate 316 is welded to the main cable ear plate 315 and the crossbeam body 33, and the lower part is welded to the first diagonal rod connecting plate 317.

[0054] Among them, the second platform of the connecting end 32 includes a second connecting plate 321, and the second through hole is set in the second connecting plate 321 for embedding the insertion rod 311. The second main cable ear plate 322 and the beam body 33 are welded on the upper part of the second connecting plate 321, and the second diagonal rod connecting plate 323 is welded on the lower part close to the side of the beam body 33.

[0055] Specifically, the pile structure 4 includes a support pile 41, and a grouting layer is provided between the top hole wall of the support pile 41 and the insertion rod 311 to fix the insertion end 31 after eliminating the pile sinking error, so that the connected structure is reliable and has good corrosion resistance. The support pile 41 is a steel pipe pile, and the insertion rod 311 of the insertion beam 3 is inserted into the top hole of the support pile 41. After the installation of the insertion beam 3 is completed, the insertion rod 311 is grouted and connected to the support pile 41, and the insertion rod 311 is fixed to the support pile 41, so that the connection end 32 can be fixedly connected to the insertion end 31 of another insertion beam 3 by a positioning pin bolt. Among them, since the outer diameter of the insertion rod 311 is smaller than the inner diameter of the support pile 41, the insertion rod 311 can move forward, backward, left and right within a certain range in the support pile 41 to adapt to the pile sinking error, reduce the pile sinking accuracy requirements, and also solve the problem of installation accuracy of the beam body 33, so as to achieve rapid installation of the beam body 33.

[0056] Among them, the first platform and the second platform are respectively provided with the first diagonal rod connecting plate 317 and the second diagonal rod connecting plate 323; the pile structure 4 is provided with a diagonal rod clamp 42, and there is a gap between the diagonal rod clamp 42 and the pile top of the pile structure 4, and the diagonal rod 43 is connected between the diagonal rod clamp 42 and the first diagonal rod connecting plate 317 or the second diagonal rod connecting plate 323. One end of the diagonal rod 43 is first anchored with the first diagonal rod connecting plate 317 or the second diagonal rod connecting plate 323 of the middle inserted cross beam 3, and then the installation position of the diagonal rod clamp 42 on the support piles 41 on both sides is determined. The diagonal rod 43 is anchored to connect the first diagonal rod connecting plate 317 or the second diagonal rod connecting plate 323 above the middle support pile 41 and the pile bodies of the support piles 41 on both sides, so as to transfer the pile top load of the middle support pile 41 to the pile bodies of the support piles 41 on both sides, thereby increasing the lateral stability of the pile structure 4.

[0057] like Figure 10-12 As shown, specifically, the photovoltaic assembly module 5 includes a crossbeam 51 and an end beam 52, and the end beam 52 is connected to the crossbeams 51 on both sides to form a basic frame connected to the photovoltaic panel; a central transverse connecting plate 54 is provided on the end beam 52 on one side of the photovoltaic assembly module 5, and edge transverse connecting plates 55 are provided on both sides of the end beam 52 on the opposite side, and the two ends of the adjustable connecting rod 7 are respectively connected to the central transverse connecting plate 54 and the edge transverse connecting plate 55, and both ends of the adjustable connecting rod 7 are spirally set with adjustable length. Two adjustable connecting rods 7 are provided, and two holes are provided in the central transverse connecting plate 54, so that the central transverse connecting plate 54 and the edge transverse connecting plate 55 can be anchored by the adjustable connecting rod 7.

[0058] The cross beams 51 and end beams 52 of the basic frame are rectangular steel pipes, two each. The basic frame is provided with diagonal braces 53 between the cross beams 51 on both sides, 4 diagonal braces 53 are welded above the two cross beams 52, 5 purlin brackets 56 are provided on the outside for installing 4 photovoltaic panels, and the pressure plate type block cable connection structure 6 is welded at both ends. The diagonal braces 53 and purlin brackets 56 are angle steels. The end beams 52 are welded at both ends of the cross beams 51, a central transverse connecting plate 54 is provided in the middle of the end beams 52, and edge transverse connecting plates 55 are provided at both ends of the end beams 52.

[0059] In this embodiment, the main structure of the photovoltaic module 5 adopts a rectangular steel pipe welding structure, that is, the cross beam 51 and the end beam 52 of the photovoltaic module 5 are made of rectangular steel pipes, and the diagonal brace 53 can be made of a small-section rectangular steel pipe or angle steel, and the module steel structure is welded in the factory. Compared with the traditional photovoltaic module module 5, the main structure is made of C-shaped steel. Due to the existence of openings, the stability and corrosion resistance of C-shaped steel are poor. The cross-section of the rectangular steel pipe is closed, and its stability and corrosion resistance are better than those of the traditional C-shaped steel, so the material consumption is more economical. The advantage of traditional C-shaped steel is that it can be bolted on site, which is convenient to connect, but the photovoltaic module 5 adopts the method of welding in the factory, and the welding speed and quality are reliable, and it does not need to be connected on site.

[0060] like Figure 13-15 As shown, specifically, the pressure plate type block cable connection structure 6 includes a first cable guide plate 61, a lower pressure block 62 and an upper pressure block 63. The first cable guide plate 61 is connected to the cross beam 51 or the end beam 52, and a groove portion cooperating with the cable structure 2 is arranged therein; the lower pressure block 62 and the upper pressure block 63 are arranged in an open-close connection, and are connected to the cross beam 51 or the end beam 52. The lower pressure block 62 and the upper pressure block 63 are arranged in a fitting area to cooperate with the cable structure 2, and the groove portion and the slot hole have the same elevation on the same side.

[0061] Among them, the first cable guide plate 61 is welded to the two ends of the crossbeam 51 of the photovoltaic module 5, and is in the shape of a "concave" groove, and the diameter of the bottom of the groove is consistent with the diameter of the cable structure 2, so as to facilitate the installation of the cable structure 2 and ensure the vertical installation of the photovoltaic module 5 and the cable structure 2. The lower pressing block 62 is welded to the crossbeam 51 of the photovoltaic module 5. The diameter of the slot of the lower pressing block 62 is consistent with the diameter of the cable structure 2 and is located on the same straight line as the slot of the cable guide block 61, ensuring the installation accuracy of the cable structure 2 and the lower pressing block 62. The diameter of the slot of the upper pressing block 63 is consistent with the diameter of the cable structure 2; after the lower pressing block 62 and the cable structure 2 are installed, the upper pressing block 63 and the lower pressing block 62 are connected by bolts to fix the cable structure 2 and the photovoltaic module 5.

[0062] Compared with the traditional block cable connection structure, the pressure plate type block cable connection structure 6 of this embodiment adopts U-shaped bolt connection, and its connection structure is simple, but the nut of the U-shaped bolt is set inside the C-shaped steel, which cannot adapt to automated installation. With the pressure plate type block cable connection structure 6, the connecting bolts are on the top of the pressure plate, which is convenient to tighten the bolts and can adapt to automated installation requirements.

[0063] like Figure 19-20 As shown, specifically, a double-cable longitudinal cable bridge structure 8 is arranged between adjacent installation spaces, and the double-cable longitudinal cable bridge structure 8 includes a bridge crossbeam 81, and a cable bridge located between adjacent cable structures 2 is hung below the bridge crossbeam 81, and a second cable guide plate 82 connected to the cable structure 2 is arranged below the bridge crossbeam 81. The bridge crossbeam 81 is an angle steel, and two second cable guide plates 82 are welded to both ends of the bridge crossbeam 81, with the notches facing downward, so that the double-cable longitudinal cable bridge structure 8 is embedded and hung on the adjacent cable structures 2.

[0064] In this embodiment, a cable bridge is provided between adjacent photovoltaic assembly modules 5 as a longitudinal cable channel to facilitate the connection of cables; this channel can also be used as a pedestrian passage during construction and operation and maintenance, facilitating construction and operation and maintenance.

[0066] S1: prefabricate the inserted cross beam 3 and the photovoltaic module 5 on the shore, and pre-weld the pressure plate type block cable connection structure 6 on the cross beam 51 of the photovoltaic module 5;
