Description

Technical Field

[0001] This utility model relates to offshore substations, specifically to a prefabricated offshore substation cabin fixing clamp and an offshore substation. Background Technology

[0002] With the continuous development and progress of economy and civilization, the world is in an environment of vigorously developing a low-carbon economy. How to develop efficient, clean, and renewable new energy sources has become a common issue for countries around the world. Wind energy, with its large volume and zero pollution, is one of the renewable energy sources that has attracted great attention from countries around the world. Over the past few decades, the global installed capacity of wind power has increased by 28%, making it the "main force" of renewable energy power generation. The world's oceans cover a vast area, accounting for about 70% of the global surface, and offshore wind energy resources are about three times that of onshore wind energy resources, possessing abundant resource reserves and development prospects.

[0003] Offshore wind farms mainly consist of two core modules: wind turbines and offshore substations. As the heart of offshore wind power, the offshore substation is the core of the project's technology, possessing functions such as energy collection, voltage boosting, and transmission. Compared to conventional offshore substations, prefabricated modular substations can reduce the need for secondary beams and diagonal braces by combining modular prefabricated modules with the main structure, thus reducing the weight of the upper modules. Furthermore, by breaking down a monolithic substation into several separate structures, the number of work surfaces for structural construction and equipment installation is increased, effectively shortening the overall construction period. Therefore, modular prefabricated modular offshore substations represent the future development trend for offshore substations.

[0004] Currently, the prefabricated modules in prefabricated offshore substations are connected to the main structure by welding, with no other securing method available. As the core of offshore wind farms, offshore substations face harsh marine environments, making their safety paramount. Therefore, a new type of securing fixture for the prefabricated modules of offshore substations is urgently needed. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the prefabricated cabin installation reliability of prefabricated substations in harsh marine environments is insufficient. This utility model provides a convenient, reliable and highly applicable prefabricated cabin fixing fixture and substation for offshore substations.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A prefabricated substation module fixing clamp includes a base, a fixing plate, and a thrust nut, characterized by the following structural features:

[0008] The base includes a base plate and a vertical plate. The base plate and the vertical plate are connected to form a T-shaped structure. The vertical plate has at least two mounting grooves and mounting holes are provided between adjacent mounting grooves.

[0009] The fixing plate includes a mounting plate, a support plate, and studs. At least two support plates and one end of at least one stud are connected to the mounting plate. The middle part of the support plate is inserted into the mounting groove on the upright plate, and the stud is inserted into the mounting hole on the upright plate.

[0010] The thrust nut is located on the stud between the upright plate and the mounting plate, and is threadedly connected to the stud.

[0011] Preferably, the thickness of the support plate is not greater than the width of the mounting groove, and the diameter of the stud is not greater than the diameter of the mounting hole.

[0012] Preferably, the stud is centrally arranged between adjacent support plates.

[0013] Preferably, the mounting hole is a round hole.

[0014] Based on the same inventive concept, this utility model also provides an offshore booster station, which includes a prefabricated cabin and a main structure, characterized in that the prefabricated cabin is located on the structural beam of the main structure, and the prefabricated cabin and the main structure are connected by the fixing clamp.

[0015] Preferably, the bottom beam of the prefabricated cabin and the structural beam of the main structure are both made of H-beams. The cladding plate is attached to the web of the bottom beam of the prefabricated cabin and welded together. The support plate is welded to the flange plate of the bottom beam of the prefabricated cabin and welded together. The bottom plate is attached to the flange plate of the main structure beam and welded together. The base is welded to the fixing plate as a whole. The thickness of the bottom plate is the same as the thickness of the flange plate of the bottom beam, and the height of the cladding plate is less than the height of the web of the bottom beam.

[0016] Preferably, the bottom beam of the prefabricated cabin is a square steel, the structural beam of the main structure is an H-beam, the cladding plate is attached to the side plate of the bottom beam of the prefabricated cabin and welded together, the bottom plate is attached to the flange plate of the structural beam of the main structure and welded together, and the base is welded to the fixing plate as a whole; the height of the cladding plate is less than the height of the square steel.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1) The fixing clamp of this utility model is used for the installation and connection of prefabricated cabins, which increases the fixing method of the prefabricated cabins of offshore substations to the main structure and improves the safety of fixing the prefabricated cabins of offshore substations.

When in use, the position of the base and the fixing plate can be adjusted according to the installation needs before welding and fixing the base and the fixing plate, which improves the practicality of the fixing clamp for the prefabricated cabin of the offshore substation.

[0020] 3) This utility model can fix the prefabricated cabin of the offshore substation using only three components: base, fixing plate and thrust nut, which improves the convenience of fixing the prefabricated cabin of the offshore substation. Attached Figure Description
