Description

Technical Field

[0001] The present invention relates to a transport tool for a large offshore photovoltaic platform based on a 1000t transport barge. Background Art

[0002] Offshore photovoltaics involve constructing solar photovoltaic power generation systems in marine environments, such as nearshore and on mudflats. This effectively utilizes vast marine resources, reduces the use of land resources, and minimizes environmental impact. Currently, offshore photovoltaic systems offer two main types of structures: floating and pile-based. An offshore photovoltaic project in Shandong Province utilizes a pile-based structure. An offshore photovoltaic system consists of a photovoltaic platform and four piles driven into the sea. The photovoltaic platform is a truss structure, with photovoltaic modules mounted on its top surface. Considering the bearing capacity of the piles and the overall stability of the photovoltaic platform, the larger the photovoltaic platform, the more photovoltaic modules can be installed, the greater the capacity, and the higher the return on investment.

[0003] Currently, photovoltaic platforms have dimensions of 60m (length × width × height) by 30m (length × width × height) by 2.5m (height) and weigh approximately 85t. Compared to traditional offshore structures, photovoltaic platforms are larger in size and relatively lighter in weight. Transporting photovoltaic platforms from the manufacturing dock to the offshore construction site is most commonly, economically, and safely accomplished by barge. Traditionally, a barge with an effective deck load area exceeding 60m (length × width × height) by 30m (height) is used to lower the entire photovoltaic platform onto the barge's deck for reinforcement. Barges capable of meeting this effective deck load area typically weigh over 5,000t. Since the photovoltaic platform weighs only 85t and has a transport volume of up to 939 voyages, the 5000t transport barge has a high draft, some aircraft spaces need to wait for the tide to enter, and the transportation cost is high. Therefore, it is more economical to use a small 1000t transport barge to transport the photovoltaic platform. However, the deck width of the 1000t transport barge does not meet the width of the photovoltaic platform. Therefore, it is urgent to design a transport tooling that is suitable for the 1000t transport barge and can meet the size requirements of the photovoltaic platform. Summary of the Invention

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide a transport tooling for a large offshore photovoltaic platform, which can realize the transportation of the offshore photovoltaic platform more economically and reduce the transportation cost.

[0005] The object of the present invention is achieved as follows: a transport tooling for a large offshore photovoltaic platform is installed on the deck of a small transport barge and includes a support truss, four support cylinders and an anti-collision mechanism; wherein,

[0006] The support truss comprises two transverse frames fixed to the deck of the small transport barge, one in front and one behind; each transverse frame is in the shape of an isosceles trapezoid and comprises a lower crossbar, two transverse diagonal braces whose lower ends are connected to the two ends of the lower crossbar in a one-to-one correspondence, an upper crossbar spanning between the upper ends of the two transverse diagonal braces, and two transverse vertical braces fixed in a one-to-one correspondence between the two ends of the upper crossbar and the lower crossbar; the length of the lower crossbar is greater than the width of the deck of the small transport barge, and the length of the upper crossbar is equal to the width of the deck of the small transport barge;

[0007] The four support tubes are fixed one by one on the top surfaces of the two ends of the lower cross bars of the two horizontal frames. The rectangle formed by the center connection of the four support tubes is adapted to the size of the rectangle formed by the center connection line of the four inverted cone-shaped fulcrum seats at the bottom of the photovoltaic platform;

[0008] The anti-collision mechanism includes two anti-collision outer longitudinal beams, three pairs of inner anti-collision inner transverse braces and two pairs of anti-collision diagonal braces; the two anti-collision outer longitudinal beams are connected one-to-one between the two ends of the lower transverse bars of the two transverse frames and are located one-to-one outside the port and starboard sides of the small transport barge; the outer ends of the three pairs of inner anti-collision inner transverse braces are fixed one-to-one and at intervals on the inner side surfaces of the two anti-collision outer longitudinal beams, and the inner bottoms of the three pairs of inner anti-collision inner transverse braces are fixed on the deck of the small transport barge; each pair of anti-collision diagonal braces is in an eight-shape, and the two pairs of anti-collision diagonal braces are fixed one-to-one outside the two ends of the two transverse frames, and the inner ends of the two pairs of anti-collision diagonal braces are fixed one-to-one on the two ends of the two outer anti-collision longitudinal beams, and the bottoms of the two pairs of anti-collision diagonal braces are fixed on the deck of the small transport barge.

[0009] In the above-mentioned transport tooling for the large offshore photovoltaic platform, a lifting lug is fixed to the top of each of the two transverse diagonal bracing rods of the two transverse frames of the supporting truss.

[0010] The above-mentioned transport tooling for the large offshore photovoltaic platform, wherein the anti-collision mechanism also includes a plurality of pairs of anti-collision pads, each of which is hung on the outer side surfaces of the two anti-collision outer longitudinal beams in a one-to-one correspondence and at intervals through iron chains.

[0012] The transport tooling for a large offshore photovoltaic platform of the present invention has the following characteristics:

[0013] By welding extra-wide support trusses onto the deck of a 1000t transport barge, the problem of the photovoltaic platform's extra-wide support trusses being unsupported outside the ship's side was resolved, eliminating the need for a large transport barge and achieving greater economic efficiency. Due to its shallow draft, the 1000t transport barge is more suitable for transport operations in shallow waters, preventing the vessel from running aground. This significantly improves construction efficiency and vessel safety, enabling more economical transport of offshore photovoltaic platforms and reducing transportation costs.

[0023] The four support tubes 2 are fixed one by one on the top surfaces of the two ends of the lower cross bar 111 of the two horizontal frames 10. The size of the rectangle formed by the center connection of the four support tubes 2 is adapted to the size of the rectangle formed by the center connection line of the four inverted cone-shaped fulcrum seats 201 at the bottom of the photovoltaic platform 200; each support tube 2 and the lower cross bar 111 are welded and reinforced by the elbow plate 20, the wing plate elbow plate 21, the cylinder elbow plate 22 and the anti-tilt elbow plate 23 to ensure the structural stability of the support tube 2.

[0024] The anti-collision mechanism includes two anti-collision outer longitudinal beams 31, three pairs of inner anti-collision inner transverse braces 32, two pairs of anti-collision diagonal braces 33 and five pairs of anti-collision pads 34; wherein,

[0025] Two anti-collision outer longitudinal beams 31 are connected one-to-one between the two ends of the lower crossbars 111 of the two transverse frames 10. The two anti-collision outer longitudinal beams 31 are located one-to-one outside the port side and the starboard side of the small transport barge 100.

[0026] The outer ends of the three pairs of inner anti-collision inner cross braces 32 are fixed to the inner side surfaces of the two anti-collision outer longitudinal beams 31 in a one-to-one correspondence and at intervals, and the inner bottoms of the three pairs of inner anti-collision inner cross braces 32 are welded and fixed to the deck of the small transport barge 100;

[0028] The five pairs of anti-collision pads 34 are each hung on the outer side of the two anti-collision outer longitudinal beams 31 in a one-to-one and interval manner through iron chains and correspond one-to-one with the lower cross bars 111 of the two transverse frames 10 and the three pairs of inner anti-collision inner cross braces 32; the anti-collision pads 34 are made of thick rubber material.

[0029] The personnel passages include two longitudinal personnel passages 41, four side transverse personnel passages 42 and two middle transverse personnel passages 43;

[0030] Two longitudinal personnel passages 41 are arranged on the inner side surfaces of the two anti-collision outer longitudinal beams 31 in a one-to-one correspondence;

[0031] The four side transverse personnel passages 42 are arranged one by one on the inner side surfaces of the two ends of the lower cross bars 111 of the two transverse frames 10;

The two anti-collision outer longitudinal beams 31 and three pairs of inner anti-collision inner cross braces 32 in the anti-collision mechanism can not only protect the left and right sides of the hull from being hit by other ships, but also connect the two transverse frames 10 to strengthen the strength of the support truss. The anti-collision pad 34 acts as a berthing squeeze buffer. The personnel passage is convenient for workers to pass through and conduct the command and reinforcement of the photovoltaic platform 200. The support tube 2 can also be used to simply and clearly check the assembly accuracy of the four legs of the photovoltaic platform 200 to avoid deviations in the leg assembly accuracy that may cause the photovoltaic platform 200 to be unable to accurately dock with the top of the pile foundation.
