Description

TECHNICAL FIELD

[0001] The present application relates to the offshore photovoltaic power generation technical field, and in particular to a double-cable module type offshore photovoltaic supporting structure. BACKGROUND

[0002] As a renewable clean energy, photovoltaic power generation has become the mainstream and reality of energy production development. Among them, the multi-span single-cable photovoltaic support structure is a typical structure in the offshore flexible photovoltaic support structure, which adopts a single-cable, module type structure, i.e. a photovoltaic module is placed between two cables, and two adjacent photovoltaic modules share a cable; a pile-cable connection structure is adopted, and the cable is directly connected with the pile, and one pile corresponds to one cable. This technology has the following defects:

[0003] (1) The traditional single-cable structure, i.e. one pile corresponds to one cable, because the construction sequence is to sink the pile first and then pull the cable, so the position of the cable is determined by the position of the pile. However, because the photovoltaic module error is small, the installation precision is high, so the cable spacing precision is high, i.e. the pile sinking precision is high. This results in more auxiliary equipment and auxiliary processes during pile sinking, slow sinking construction speed and high cost.

[0004] (2) Two adjacent photovoltaic modules share a cable, and are connected by bolts, so the position of the later installed module is determined by the position of the earlier installed module, and the positions of the adjacent modules strictly correspond and the module installation precision is high. Therefore, more auxiliary equipment and auxiliary processes are required during module installation, resulting in slow installation speed and high cost.

[0005] (3) Two adjacent photovoltaic modules share a cable, and the later installed module is fixed on the cable during installation. This results in that there is already a structure on the cable during module installation, and the module cannot slide on the cable, so the single-cable structure cannot adapt to automatic sliding installation.

[0006] (4) The cable is directly connected with the pile, and one pile corresponds to one cable, the cross beam is installed between two piles after the pile is sunk first, and the cross beam is connected with the pile by bolts, but the cross beam is manufactured on land, and the installation precision is high. This results in difficult cross beam installation, slow installation speed and high cost. SUMMARY

DETAILED DESCRIPTION

[0042] A four-span double-column double-cable modular offshore photovoltaic support structure is listed below, and the present application is further described in conjunction with the drawings and examples, but not as the basis for limiting the present application.

[0043] As shown in Figures 1-3 , a double-cable modular offshore photovoltaic support structure is provided between the top of the transversely adjacent pile structures 4, and the inserted cross beam 3 is provided at the head and tail ends of the inserted cross beam 3, respectively. The adjacent inserted cross beams 3 are connected at the head and tail of the same pile structure 4, and the inserted end 31 is inserted and matched with the pile top hole; the inserted end 31 and the connecting end 32 in a single inserted cross beam 3 are provided with hanging points connected with the cable structure 2, and the hanging points in the inserted end 31 and the connecting end 32 of the same pile top have intervals; two cable structures 2 are connected between longitudinally adjacent inserted cross beams 3 to form an independent installation space for photovoltaic module 5 between longitudinally adjacent inserted cross beams 3, and the photovoltaic module 5 is provided at the end with a pressure plate type block cable connection structure 6 connected with the cable structure 2 to form a sliding installation state or a fixed point stable state of the photovoltaic module 5 on the cable structure 2, and the photovoltaic modules 5 in the adjacent installation spaces are provided with rigid adjustable connecting rods 7.

[0044] The embodiment is provided with four longitudinal cable structures 2 and two transverse cable structures 2, each cable structure 2 is provided with seven photovoltaic module groups 5, and each photovoltaic module group 5 is provided with four photovoltaic panels. The pile structure 4 is provided with five transverse rows and three longitudinal rows, that is, a total of 15 groups. The anchoring structure 1 is provided on the longitudinal sides of the double-cable module type offshore photovoltaic support structure, and each anchoring structure 1 is provided with three groups and is located on the same line as the pile structure 4.

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

[0046] In the embodiment, the adjacent two photovoltaic module groups 5 do not share the cable structure 2, and only one photovoltaic module group 5 is installed on one cable structure 2. When the photovoltaic module group 5 is installed by sliding, there is no obstacle, and automatic sliding installation of the photovoltaic module group 5 can be realized.

[0047] As shown in Figures 1-3 The anchoring structure 1 is composed of an end foundation pile 11, a pile cap 12 and an ear 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 from the cable structure 2 to the anchoring structure 1. The pile cap 12 is a steel structure fixed on the end foundation pile 11. The ear plate 13 is located above the pile cap 12 and is fixedly connected with the pile cap 12. The ear plate 13 has a hole, and the cable structure 2 can be fixed on the anchoring structure 1.

[0048] As shown in Figures 3-9 Specifically, the plug-in cross beam 3 includes a frame type cross beam body 33, the two ends of the cross beam body 33 are respectively connected and fixed with the plug-in end 31 and the connecting end 32, and the lower side of the cross beam body 33 is connected with a cable bridge beam 34 and an inverter bridge beam 35.

[0049] In the embodiment, the beam body 33 of the frame structure comprises a beam main material 331, a beam horizontal rod 332 and a beam inclined rod 333. The beam main material 331 is a channel steel, and the beam horizontal rod 332 and the beam inclined rod 333 are flat steels. The beam main material 331 comprises two channel steels, and the two channel steels are oppositely arranged. One beam horizontal rod 332 and 11 beam inclined rods 333 are arranged at the upper and lower ends of the two channel steels, and the two ends are welded with the insertion end 31 and the connection end 32 respectively. Two cable bridge beams 34 are welded below the two ends of the beam body 33, and a cable bridge is arranged above the cable bridge beams 34. An inverter bridge beam 35 is welded in the middle of the beam body 33, and an inverter is arranged above the inverter bridge beam 35. The cable bridge beam 34 and the inverter bridge beam 35 are both welded by angle steels. The insertion beam 3 is welded and fixed in the factory, and then the on-site construction is carried out at sea.

[0050] The insertion end 31 comprises an insertion rod 311 inserted into the hole of the pile top and a first platform, and a first through hole connected with the insertion rod 311 is arranged in the first platform. The connection end 32 comprises a second platform, and a second through hole matched with the insertion rod 311 is arranged in the second platform, so that the insertion end 31 of the same pile top is inserted and matched with the connection end 32 through the insertion rod 311. Meanwhile, the height of the first platform is greater than the height of the second platform. In the embodiment, the insertion rod 311 is a cylindrical solid steel pipe with sharp ends, and the diameter is less than the inner diameter of the support pile 41.

[0051] The first main cable ear plate 315 is arranged on the first platform, and the first main cable ear plate 315 is welded with the beam 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 of the longitudinal sides through the first connecting hole to anchor the cable structure 2. The second main cable ear plate 322 is arranged on the second platform, and the second main cable ear plate 322 is welded with the beam 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 of the longitudinal sides through the first connecting hole to anchor the cable structure 2. The first connecting hole and the second connecting hole are arranged in the same plane.

[0052] In the embodiment, the hanging point of the cable structure 2 is arranged on the beam body 33, that is, the position of the cable is determined when the insertion beam 3 is manufactured, and does not depend on the pile sinking accuracy. When the insertion beam 3 is manufactured alone, the accuracy can be maintained at a high level, so that the installation accuracy of the cable structure 2 is decoupled from the pile sinking accuracy by this technology, the installation accuracy of the cable structure 2 is high, the requirement for the pile sinking accuracy is low, the pile sinking construction is facilitated, the pile sinking speed is accelerated, and the pile sinking cost is reduced.

[0053] The first platform comprises 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 through 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, the first through hole in the upper end plate 312 and the lower end plate 314 is used for placing the insertion rod 311, and the upper end plate 312 and the lower end plate 314 are connected by welding; the reinforcing plate 313 is arranged at an equal angle along the circumference of the insertion rod 311, and four reinforcing plates 313 are arranged to strengthen the connection with the insertion rod 311. Meanwhile, the upper end plate 312 is welded with a first connecting plate 316, the upper part of the first connecting plate 316 is welded with the main cable ear plate 315 and the beam body 33, and the lower part is welded with a first inclined rod connecting plate 317.

[0054] The second platform of the connecting end 32 comprises a second connecting plate 321, a second through hole is arranged in the second connecting plate 321 and used for sleeving and embedding the insertion rod 311, the upper part of the second connecting plate 321 is welded with a second main cable ear plate 322 and a beam body 33, and the lower part is welded with a second inclined rod connecting plate 323 close to one side of the beam body 33.

[0055] Specifically, the pile structure 4 comprises a support pile 41, and a grouting layer is arranged between the hole wall of the top of the support pile 41 and the insertion rod 311, so as to fix the insertion end 31 after the elimination of 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 type beam 3 is inserted into the hole in the top of the support pile 41. After the insertion type beam 3 is installed, the insertion rod 311 is connected with the support pile 41 by grouting, and the insertion rod 311 is fixed with the support pile 41, so that the connecting end 32 and the insertion end 31 of another insertion type beam 3 can be fixed and connected by a positioning pin bolt. 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 in a certain range of front, back, left and right in the support pile 41, so as to adapt to the pile sinking error, reduce the requirement for the pile sinking accuracy, and also solve the problem of the installation accuracy of the beam body 33, thereby realizing the rapid installation of the beam body 33.

[0056] The first inclined rod connecting plate 317 and the second inclined rod connecting plate 323 are arranged on the first platform and the second platform respectively; the pile structure 4 is provided with an inclined rod hoop 42, the inclined rod hoop 42 has a space with the top of the pile structure 4, and the inclined rod 43 is arranged and connected between the inclined rod hoop 42 and the first inclined rod connecting plate 317 or the second inclined rod connecting plate 323. One end of the inclined rod 43 is first anchored with the first inclined rod connecting plate 317 or the second inclined rod connecting plate 323 of the middle insertion type beam 3, and then the installation position of the inclined rod hoop 42 on the two side support piles 41 is determined. The inclined rod 43 is anchored and connected with the first inclined rod connecting plate 317 or the second inclined rod connecting plate 323 above the middle support pile 41 and the pile body of the two side support piles 41, so as to transfer the load on the top of the middle support pile 41 to the pile body of the two side support piles 41, thereby increasing the lateral stability of the pile structure 4.

[0057] As Figures 10-12 shown, specifically, the photovoltaic module 5 includes beams 51 and end beams 52, the end beams 52 are connected with the beams 51 on both sides to form a basic frame connected with the photovoltaic panel; the end beam 52 on one side of the photovoltaic module 5 is provided with a central transverse connecting plate 54, the end beams 52 on the opposite side are provided with edge transverse connecting plates 55 on both sides, the two ends of the adjustable connecting rod 7 are connected with the central transverse connecting plate 54 and the edge transverse connecting plate 55 respectively, and the two ends of the adjustable connecting rod 7 are provided in a screw type with adjustable length. Two adjustable connecting rods 7 are provided, and two holes are provided in the central transverse connecting plate 54 so as to anchor the central transverse connecting plate 54 and the edge transverse connecting plate 55 through the adjustable connecting rod 7.

[0058] The beams 51 and the end beams 52 of the basic frame are rectangular steel pipes, each two. The basic frame is provided with diagonal braces 53 between the beams 51 on both sides, four diagonal braces 53 are welded on the two beams 52, five purlin supports 56 are provided on the outside for mounting four photovoltaic panels, and the plate type block cable connecting structure 6 is welded at both ends. The diagonal braces 53 and the purlin supports 56 are angle steels. The end beams 52 are welded at both ends of the beams 51, the central transverse connecting plate 54 is arranged in the middle of the end beam 52, and the edge transverse connecting plates 55 are arranged at both ends of the end beam 52.

[0059] In the embodiment, the main structure of the photovoltaic module 5 adopts a rectangular steel pipe welding structure, that is, the beams 51 and the end beams 52 of the photovoltaic module 5 are all rectangular steel pipes, the diagonal braces 53 can be small-section rectangular steel pipes or angle steels, and the module steel structure is welded in the factory. Compared with the traditional photovoltaic module 5 main structure made of C-shaped steel, the C-shaped steel has poor stability and poor corrosion resistance due to the opening, the rectangular steel pipe has a closed cross section, and the stability and corrosion resistance are better than the traditional C-shaped steel, so the material consumption is more economical. The advantage of the traditional C-shaped steel is that it can be connected on site by bolts, which is convenient, but the photovoltaic module 5 adopts a welding method in the factory, and the welding speed and quality are reliable, without the need for on-site connection.

[0060] As Figures 13-15 shown, specifically, the plate type block cable connecting structure 6 includes a first guide cable plate 61, and a lower pressing block 62 and an upper pressing block 63, the first guide cable plate 61 is connected with the beam 51 or the end beam 52, and a groove part matched with the cable structure 2 is arranged in the first guide cable plate 61; the lower pressing block 62 and the upper pressing block 63 are connected in an openable and closable manner, and are connected with the beam 51 or the end beam 52, a groove hole matched with the cable structure 2 is arranged in the abutting region of the lower pressing block 62 and the upper pressing block 63, and the same side elevation of the groove part and the groove hole is consistent.

[0061] The first guide cable plate 61 is welded at both ends of the cross beam 51 of the photovoltaic module 5, in the shape of a "concave" groove, and the diameter of the groove bottom 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 on the cross beam 51 of the photovoltaic module 5, and the groove hole diameter of the lower pressing block 62 is consistent with the diameter of the cable structure 2 and is located on the same straight line with the groove hole of the guide cable block 61, so as to ensure the installation accuracy of the cable structure 2 and the lower pressing block 62. The groove hole diameter 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, and the cable structure 2 and the photovoltaic module 5 are fixedly connected.

[0062] Compared with the traditional block-cable connection structure, the pressing plate type block-cable connection structure 6 of the embodiment adopts a U-shaped bolt connection, which has a simple connection structure, but the nut of the U-shaped bolt is arranged inside the C-shaped steel, which cannot adapt to automatic installation. By adopting the pressing plate type block-cable connection structure 6, the connecting bolt is arranged on the upper surface of the pressing plate, the fastening bolt is convenient, and the automatic installation demand can be met.

[0063] As shown in Figures 19-20 , specifically, a double-cable longitudinal cable bridge structure 8 is arranged between adjacent installation spaces, the double-cable longitudinal cable bridge structure 8 comprises a bridge cross beam 81, and a cable bridge located between adjacent cable structures 2 is hung below the bridge cross beam 81, and a second guide cable plate 82 connected with the cable structure 2 is arranged below the bridge cross beam 81. Among them, the bridge cross beam 81 is an angle steel, two second guide cable plates 82 are welded at both ends of the bridge cross beam 81, and the notches are downward, so that the double-cable longitudinal cable bridge structure 8 is embedded and hung on the adjacent cable structures 2

[0064] In the embodiment, a cable bridge is arranged between adjacent photovoltaic modules 5 as a longitudinal cable channel, which facilitates the connection of the cable; this channel can also serve as a pedestrian passage during construction and operation, which is convenient for construction and operation.
