Description

Technical Field

[0001] The utility model belongs to the field of offshore photovoltaic boosting stations, and in particular relates to an offshore photovoltaic boosting station. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] At present, all projects using offshore booster stations are offshore wind power projects with a water depth of more than 10m. The offshore booster stations weigh more than 2,500t and are integral frame structures, which are hoisted as a whole by large floating cranes. Most offshore photovoltaic sites are near the coast with a water depth of 3-4m, or even in the mudflats. Large floating cranes have a draft of more than 8m and cannot enter the site for operation due to water depth restrictions. The structure of traditional offshore wind power booster stations is not applicable. Summary of the invention

[0004] In order to solve the above problems, the utility model proposes an offshore photovoltaic booster station. The utility model can realize construction operations with a small floating crane or a crawler crane, is not restricted by water depth, and meets the needs of engineering development.

[0005] According to some embodiments, the utility model adopts the following technical solutions:

[0006] An offshore photovoltaic booster station comprises a platform and a plurality of pipe piles, wherein two sets of platform beams are arranged below the platform, the two sets of platform beams are arranged vertically, and each set of platform beams comprises a plurality of platform beams arranged in sequence at intervals;

[0007] A plurality of pipe piles are sequentially arranged on each platform beam;

[0008] The platform includes a plurality of split decks;

[0009] The platform is detachably provided with a main transformer, a fire wall and secondary equipment.

[0010] In the above scheme, split construction can be achieved through the separate setting of pipe piles, decks and the equipment thereon. Construction can be carried out using small floating cranes and crawler cranes without the need for large floating cranes. This not only solves the problem of draft restrictions on the entry of large floating cranes, but also greatly reduces the cost of lifting ship machinery.

[0011] As an optional implementation, the two groups of platform beams are arranged in X and Y directions respectively.

[0012] As an optional embodiment, the spacing distances of the platform beams in each group of platform beams are the same;

[0013] The spacing distances between platform beams of different groups of platform beams are the same.

[0014] As an optional implementation, the spacing between platform beams corresponding to the secondary equipment and main transformer areas is set to be smaller than the spacing between platform beams in other areas.

[0015] As an optional embodiment, the area of ​​each deck is greater than the product of the maximum distance between two adjacent platform beams.

[0016] As an optional implementation, the pipe piles arranged on the platform beam are spaced at the same distance.

[0017] As an optional embodiment, the deck is a steel deck with a single-layer structure.

[0018] As an optional implementation, the pipe piles are steel pipe piles or PHC pipe piles.

[0019] As an optional implementation, a firewall is provided between the secondary equipment and the main transformer.

[0020] As an optional implementation, the secondary equipment adopts a prefabricated cabin in a container model.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] The utility model can construct pipe piles, steel platforms, main transformer secondary equipment separately, and can be constructed by small floating cranes and crawler cranes without large floating cranes. It not only solves the problem of draft restrictions on large floating cranes entering the site, but also greatly reduces the cost of lifting ship machinery.

[0023] Due to the split construction, the steel platform adopts a single-layer structure and no longer has the frame structure required for overall lifting, such as lifting columns and beams, which greatly saves structural steel and reduces the project cost.

[0024] The utility model has multiple pipe piles arranged in multiple rows, and compared with the traditional four-pile structure, the overall rigidity and strength of the structure are high. The span and cross section of the beam are smaller, and the amount of steel used in the structure is further reduced.

[0025] After the steel platform is installed, it can serve as a supporting structure for the equipment and as a temporary operating platform for construction workers.

[0026] Water exchange can be achieved between the pipe piles, which are permeable structures with little impact on the marine environment.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, preferred embodiments are given below and described in detail with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

For example, in an area where the main transformer (6) and the secondary equipment (4) are to be installed, the spacing between the platform beams (2) may be reduced to increase the supporting force.

[0039] Firewalls (5), main transformers (6), secondary equipment (4) and other equipment are arranged on the upper platform and are installed by small floating cranes and crawler cranes. After the construction is completed, offshore commissioning is carried out.

[0042] Of course, in this embodiment, the size of the deck (3) needs to be larger than the spacing between adjacent platform beams (2).

[0043] After the pile driving construction of the pipe pile (1) is completed, the upper platform is hoisted, and the pipe pile (1) and the upper platform are connected by grouting or welding, and the construction joints between the steel platform blocks are spliced. The distance between the piles is 6-7m.

[0044] After the steel platform is constructed, the main transformer (6), firewall (5), secondary equipment (4) and the like can be hoisted and installed. The firewall (5) is arranged between the main transformer (6) and the secondary equipment (4). In this embodiment, the secondary equipment (4) adopts a prefabricated cabin in a container mode. After the land construction and installation is completed, a small floating crawler crane is used to hoist it into place, and then wiring and debugging work are carried out.
