specific Embodiment 1

[0023] Figure 1 to Figure 4 Constitute the specific embodiment 1 of the present invention.

[0024] refer to figure 1 and figure 2 , the specific embodiment 1 includes a seabed foundation 1 and a sea station house, and the sea station house includes a frame body 2 and a house shell; the frame body 2 has an integral three-layer space structure; the first floor 2-3 of the frame body 2 constitutes a lounge , emergency oil discharge tank and escape equipment setting space, the second layer 2-4 of the frame main body 2 constitutes the main transformer setting space, and the third layer 2-5 of the frame main body 2 constitutes the main transformer maintenance equipment setting space; The left support structure 2-1 extends from the bottom of the second layer to the left, and the right support structure 2-2 extends to the right. The left prefabricated box 3 is connected to the left support structure 2-1, and the right support structure 2- 2 is connected with the right prefabrica...

specific Embodiment 2

[0051] The characteristics of the specific embodiment 2 of the present invention are: at the bottom of the second layer of the frame body 2, a left support structure 2-1 is extended to the left, and a right support structure 2-2 is extended to the right; therefore, the left prefabricated cabin and The right prefabricated cabin can be a three-layer structure. All the other are with specific embodiment 1.

[0052] Since the present invention applies the modularized prefabricated cabin to the integral offshore booster station, the modularized prefabricated cabin is used to replace the structural main columns, steel beams, braces and other structural components of the original integrated booster station to pressurize the sea The weight of the upper block and the lower foundation of the station is reduced; after the introduction of prefabricated cabins, the construction and installation period of the offshore booster station is shortened by increasing the construction work area.

Abstract

The invention relates to a modular and integral combined offshore booster station. The modular and integral combined offshore booster station comprises a seabed foundation and a sea surface station house; the sea surface station house comprises a frame main body and a house shell; the modular and integral combined offshore booster station is characterized in that the frame main body has an integral three-layer space structure; the first layer of the frame main body forms an arrangement room containing a rest room, an accident oil discharge tank and escape equipment; the second layer forms an arrangement room containing a main transformer; and the third layer forms an arrangement room containing main transformer maintenance equipment; a left supporting structure extends leftwards from the bottom of the first layer or the bottom of the second layer of the frame body; a right supporting structure extends rightwards from the bottom of the first layer or the bottom of the second layer of the frame body; a left prefabricated box is connected to the left supporting structure, a right prefabricated box is connected to the right supporting structure, and a modular combined structure is formed; and a large pipe type foundation connecting end and a small pipe type foundation connecting end are arranged on the bottom face of the frame body so as to form a fixed connecting structure with a foundation. The modular and integral combined offshore booster station has the characteristics of less steel consumption, lower material cost, shorter construction period, higher construction efficiency and the like.

Description

technical field [0001] The invention relates to an offshore booster station combining modularization and integral type. It belongs to the technical field of offshore power generation equipment in electric power. Background technique [0002] In recent years, my country's offshore wind power industry has developed rapidly, and more and more offshore wind power projects have started construction in the coastal provinces of the motherland. Offshore wind power projects can generally be divided into four parts, one is offshore wind turbines, the other is offshore booster stations, the third is submarine cables, and the fourth is onshore centralized control centers. The electric energy generated by offshore wind turbines is collected to the offshore step-up station through the 35kV power-collecting submarine cable, and the voltage is boosted from 35kV to 220kV through the offshore step-up station, and then the electric energy is transmitted from the sea to the onshore collection ...
