Description

Technical Field

[0001] The utility model relates to the technical field of offshore booster stations, and specifically relates to a modular offshore booster station. Background Art

[0002] An offshore booster station is a boosting, power distribution, and control center for an offshore wind farm. Generally, various electrical equipment such as main transformers, high and low voltage switch cabinets, GIS, and communication relay protection equipment are arranged in the offshore booster station. After collecting the electric energy generated by all offshore wind turbines, the offshore booster station steps up the voltage through the main transformer and then sends it to the onshore through high-voltage submarine cables.

[0003] When building an offshore booster station, generally, jacket foundations are driven into the seabed first, then a load-bearing platform is built on the jacket foundation, and finally, the separated modules are sequentially placed on the load-bearing platform to complete the construction of the offshore booster station. However, the load-bearing platform of the traditional offshore booster station is generally formed by pouring concrete and steel bars, which makes it inconvenient for both installation and demolition.

[0004] Therefore, many have switched to using steel caissons for bearing. However, the existing steel caissons generally adopt integral steel caissons. Due to the large cross-sectional area of the steel caissons, it is inconvenient for both transportation and installation, which greatly affects the construction efficiency. Therefore, in view of the above problems, a modular offshore booster station is proposed. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and solve the above-mentioned technical problems, the utility model proposes a modular offshore booster station.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows: A modular offshore booster station described in the utility model includes a main pile foundation pipe and multiple layers of steel caissons. The steel caissons include several H-shaped steel plates. On both sides of the steel plates, several strengthening columns are fixedly connected and erected. On both sides of the steel plates, several strengthening holes are respectively opened. The strengthening columns and the strengthening holes are arranged in a cross manner. The positions of the strengthening columns and the strengthening holes on the opposite sides of adjacent steel plates correspond one by one. On both sides of the steel plates, two groups of positioning holes are respectively opened. At the four corners of the steel plates, several fixing holes are respectively opened. A first fastening bolt is inserted into the fixing holes, and a first fastening nut is threadedly connected to the first fastening bolt. When building the offshore booster station, first drive the main pile foundation pipe into the bottom of the seabed, and then transport the segmented steel caissons to the building position by a transport ship for assembly. By arranging the steel plates closely and passing the first fastening bolt through the fixing holes of adjacent steel plates and connecting them with the first fastening nut, the steel plates are assembled to form a steel caisson. When the steel plates are assembled, the strengthening columns and the strengthening holes of the two groups of steel plates are inserted corresponding to each other, thereby improving the overall strength of the steel caisson. By using the steel caisson instead of the reinforced concrete caisson, it is convenient for construction and later disassembly, realizing reuse, and the steel plates are more convenient for transportation.

[0007] Preferably, the number of each group of the positioning holes is set to two to four.

[0008] Preferably, the steel caisson is divided into upper and lower layers. Four support columns are installed at the corresponding positioning holes on the opposite sides of the two layers of the steel caisson. The upper steel caisson is supported by the support columns, so that the steel caisson can be installed in multiple layers, thereby greatly expanding the installation space.

[0009] Preferably, the four support columns include column bodies. Support seats are fixedly connected to the upper and lower ends of the column bodies respectively. Several first mounting holes are opened on the surface of the support seats corresponding to the positioning holes.

[0010] Preferably, a second fastening bolt is installed in the first mounting holes. The second fastening bolt passes through the corresponding positioning holes and is threadedly connected with a second fastening nut. By passing the second fastening bolt through the first mounting holes and the positioning holes and connecting them with the second fastening nut, the two ends of the support column are respectively fixedly supported with the upper and lower layers of the steel caisson.

[0011] Preferably, an offshore booster station module is fixedly connected to the steel caisson. The offshore booster station module includes a main transformer module, a GIS component module, a diesel generator module, a battery module, a low-voltage power distribution module, a low-voltage communication module, a secondary equipment module, and a station service equipment module.

[0012] Preferably, support components are installed on the main pile foundation pipe and the multi-layer steel bearing platform. The support components include a number of first fixing seats and second fixing seats. Threaded columns are fixedly connected to the tops of the first fixing seats and the second fixing seats respectively. The threaded columns pass through the positioning holes at corresponding positions and are threadedly connected with fixing nuts. When connecting the main pile foundation pipe and the steel bearing platform, the threaded columns above the first fixing seats pass through the positioning holes and are connected with the fixing nuts, so as to quickly fix the steel bearing platform at the top of the main pile foundation pipe.

[0013] Preferably, the first fixing seat is welded to the top of the main pile foundation pipe.

[0014] Preferably, the bottom end of the second fixing seat is rotatably connected to a support frame. The bottom end of the support frame is rotatably connected to an arc-shaped seat, and the arc-shaped seat fits the outer wall of the main pile foundation pipe. Openings are formed on the surface of the arc-shaped seat.
