Description

Technical Field

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

[0002] Offshore photovoltaics is the construction of solar photovoltaic power generation systems in marine environments such as offshore and mudflats. It can effectively utilize vast marine resources, reduce the occupation of land resources, and reduce the impact on the environment. The current offshore photovoltaic main structures are floating and pile-fixed. A certain offshore photovoltaic project in Shandong adopts a pile-fixed structure. An offshore photovoltaic main body includes a photovoltaic platform and four piles driven in the sea. The photovoltaic platform is a truss structure, and photovoltaic modules are installed on the top surface of the photovoltaic platform. Taking into account the bearing capacity of the pile foundation and the overall stability of the photovoltaic platform, the larger the area of ​​the photovoltaic platform, the more photovoltaic modules can be installed, the larger the capacity, and the higher the return on investment.

[0003] At present, the structural dimensions of the photovoltaic platform reach length × width × height = 60m × 30m × 2.5m, and the weight is about 85t. Compared with traditional marine engineering components, the photovoltaic platform has the characteristics of large structural dimensions and relatively light weight. The most common, economical and safe means of transportation for transporting the photovoltaic platform from the manufacturing dock to the offshore construction site is to use a transport barge. The traditional mode of transportation is to use a transport barge with an effective deck load area exceeding length × width = 60m × 30m, and to drop the photovoltaic platform as a whole onto the deck of the transport barge for reinforcement. The transport barge that can meet the above effective deck load area is usually more than 5,000t. Since the weight of the photovoltaic platform is only 85t, the transportation volume is as high as 939 voyages, the 5000t transport barge has a high draft, some aircraft positions need to wait for the tide to enter and the transportation cost is high, so 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 can be 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 transport 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 one in front of the other on the deck of the small transport barge; each transverse frame is in an isosceles trapezoidal shape 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 one-to-one 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 cylinders are fixed one by one on the top surfaces of the two ends of the lower cross bars of the two horizontal frames, and the size of the rectangle formed by the center connection of the four support cylinders is adapted to the size of the rectangle formed by the center connection line of the four inverted cone spherical support seats at the bottom of the photovoltaic platform;

[0008] The anti-collision mechanism comprises 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 side and the starboard side 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-shaped shape, 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 each of the tops of the two transverse diagonal braces 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.

[0011] The above-mentioned transport tooling for the large offshore photovoltaic platform, wherein the transport tooling also includes a longitudinal personnel passage arranged on the inner side surfaces of two anti-collision outer longitudinal beams, four side transverse personnel passages arranged one-to-one on the inner side surfaces of both ends of the lower cross bars of the two transverse frames, and two middle transverse personnel passages arranged one-to-one on one side surface of a pair of inner anti-collision inner cross braces.

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

[0013] By welding an extra-wide support truss on the deck of the 1000t transport barge, the problem of the photovoltaic platform's extra-wide support truss being unsupported outside the ship's side was solved, and there was no need to use a large transport barge, which was highly economical. Since the 1000t transport barge has a shallow draft, it is more suitable for transport operations in shallow waters to avoid the ship from running aground, greatly improving construction efficiency and ship safety, and enabling more economical transportation of offshore photovoltaic platforms and reducing transportation costs.
