Description

Technical Field

[0001] The present invention relates to the technical field of booster stations, and in particular to a module prefabricated offshore booster station. Background Art

[0002] Wind power generation is one of the main renewable energy sources. After decades of development, onshore wind power technology has become very mature. Offshore wind power generation is a new direction for global energy development and the pinnacle of wind power generation technology. Onshore wind power in my country has been developed on a large scale, and the installed capacity has jumped to the first place in the world, while the development of offshore wind power has just started. The booster station is an important part of the electrical system of the wind farm and is responsible for the transmission of wind farm electricity. When the offshore wind farm has a large capacity and is far from the shore, it is generally necessary to build an offshore booster station to collect the electricity generated by the wind turbines, boost it to a high voltage level and transmit it to the onshore power grid. At present, there is no unified standard and structure for offshore booster stations, but the structural form of offshore booster stations has an important impact on their installation, transportation, operation and maintenance, and economy.

[0003] Therefore, the utility model patent with patent application number CN201520095751.6 announced a "modular prefabricated offshore booster station", which uses standardized containers to pack various booster station component modules for easy transportation and to reduce manufacturing and later installation costs. However, in actual use, since the standardized container needs to be fixed by corner fittings at the four corners, the traditional fixing method is generally fixed by twist locks or lashing rods. Traditional twist locks are generally used to fix between upper and lower layers or adjacent containers, and it is impossible to stably fix the container body on the deck of the booster station platform. The lashing rods need to be attached to the outer wall of the container, which hinders the opening of the container door and the laying of cable ducts.

[0004] Based on this, a modular prefabricated offshore booster station is invented and designed to solve the above problems. Summary of the invention

[0005] The purpose of the invention is to provide a modular prefabricated offshore booster station to solve the above technical problems.

[0006] To achieve the above-mentioned purpose, the invention provides the following technical solutions: a modular prefabricated offshore booster station, comprising a supporting base, a booster station platform installed on the supporting base, and a prefabricated module installed on the booster station platform, wherein the prefabricated module comprises 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 power equipment module, and a helipad platform and a crane platform are respectively arranged on both sides of the top of the prefabricated module, and a lifting crane is arranged on the crane platform;

[0007] The pre-installed modules are respectively arranged in respective independently closed prefabricated container bodies, the top and bottom four corners of the prefabricated containers are provided with container corner fittings, and the booster station platform is fixedly provided with a self-locking mounting seat at the position of the bottom container corner fitting corresponding to each prefabricated container.

[0008] Preferably, the prefabricated container is provided with a movable door, and the prefabricated container body is also provided with internal lighting, internal decoration, heating and air conditioning facilities.

[0009] Preferably, the self-locking mounting seat includes a square shell base with an open top, a trigger sleeve is arranged at the center of the inner cavity of the square shell base, the bottom of the inner cavity of the trigger sleeve is movably connected to the bottom of the square shell base by passing a fixed sliding column, and slide groove ears are fixed on the adjacent two sides of the trigger sleeve, and self-locking pressure plates are hingedly arranged on the two sides corresponding to the square shell base and the slide groove ears, the outer side of the self-locking pressure plate is hinged to the side wall of the square shell base through the bolt shaft, the inner end of the self-locking pressure plate is hinged to the slide groove ear through a pin bolt, and the inner wall of the upper end of the self-locking pressure plate is provided with a self-locking protrusion matching the slot hole of the container corner piece.

[0010] Preferably, a return compression spring is sleeved on the outer wall of the fixed sliding column, and the return compression spring abuts between the bottom of the trigger sleeve and the square shell base.

[0011] Preferably, the square shell base is welded by a square bottom plate and a square surrounding wall, the square bottom plate is fixedly welded to the top surface of the booster station platform, and reinforcing ribs are welded between the surrounding outer walls of the square surrounding wall and the top surface of the square bottom plate.

[0012] Preferably, the self-locking pressure plate includes two mirror images of each other, and the self-locking pressure plate includes an L-shaped pressure plate body, the self-locking protrusion is arranged on the inner side of the upper end of the L-shaped pressure plate body, and the bottom of the L-shaped pressure plate body is alternately arranged with outer pin holes and inner pin holes, and the inner pin holes cooperate with the pin shaft bolts, and the upper end of the L-shaped pressure plate body is provided with locking ears extending outward along the horizontal plane.

[0013] Preferably, the bolt shaft comprises a pin rod, a threaded column and an external hexagonal portion which are coaxially arranged in sequence, and the pin rod, the threaded column and the external hexagonal portion are an integrated structure.

[0014] Compared with the prior art, the invention has the following beneficial effects:

[0015] The modular prefabricated offshore booster station of the present invention mainly comprises a supporting base, a booster station platform and a prefabricated module. A self-locking mounting seat is fixedly arranged at the bottom container corner fitting position of each prefabricated container on the booster station platform. The self-locking mounting seat is specially used to stably fix the prefabricated container on the deck of the booster station platform. When the self-locking mounting seat is in use, the sleeve is triggered by the automatic downward pressure of the prefabricated container and the prefabricated module, thereby forcing the self-locking pressure plates on both sides to fit and buckle with the container corner fittings to achieve lateral limit fixing. The upper end of the L-shaped pressure plate body in the self-locking mounting seat extends outward along the horizontal plane. Locking ears are provided. After the prefabricated container is placed, the two sets of locking ears fit each other. The two are coaxially penetrated by a simple latch rod or bolt to achieve a locking effect. The self-locking mounting seat structure adopted in this booster station is characterized in that, first, the prefabricated container cannot be laterally offset unless it is lifted. The advantage of this fixing method is that it can effectively prevent the prefabricated module from being loosened due to force when a typhoon blows at sea or the terrain shakes. Second, the latch rod or bolt used for the locking structure does not directly bear weight, which can avoid the problem of difficult disassembly and maintenance after rusting due to the traditional direct fixing with bolts.
