Abstract

The utility model relates to offshore wind farm pylon field, particularly relates to the changeover portion of jacket-type marine wind electric field foundation structure.It comprises central post, crossbeam and supporting leg, and described crossbeam one end is arranged on described central post side, and described supporting leg is arranged on the described crossbeam other end.Described crossbeam has 4, and described supporting leg has 4, and described supporting leg is cylindrical.The utility model has the advantage of and adopt integral transition segment structure, eliminate the shortcoming of stress high concentration, the Rigidity and strength configuration of structure rationally, rate of utilization of strength is high, avoid fatigue damage concentrations, instead of traditional split design, improve the fatigue life of structure.

Description

The changeover portion of jacket-type marine wind electric field foundation structure
Technical field
The utility model relates to offshore wind farm pylon field, particularly relates to the changeover portion of jacket-type marine wind electric field foundation structure.
Background technology
Marine wind electric field foundation structure is the key component that marine wind electric field is built, and the principal mode of fixed offshore wind energy turbine set foundation structure is gravity structure, single pile structure, tripod structure, high three pileworks and jacket structure.
Present stage, the changeover portion of jacket structure mainly adopts column deck structure, and column bottom is directly welded above deck, and the position be connected with jacket spud leg by 4 hound support deck.Therefore, the power that strut bears is maximum, is secondly deck, and this just requires that deck has sizable rigidity, causes deck excessive deformation with the gravity load and bending load of avoiding column.Because the different diameters of strut and column is comparatively large, and strut is stressed comparatively large, and therefore, the pipe node place stress that strut is connected with column is concentrated serious, becomes the weak spot of whole foundation structure, and this is also the difficult point of jacket frame foundation structure design.
Summary of the invention
The technical problems to be solved in the utility model how to overcome the deficiencies in the prior art, provides the changeover portion that a kind of structure stress distribution is reasonable, improve the jacket-type marine wind electric field foundation structure of structure fatigue life.
The technical scheme that the utility model is adopted for achieving the above object is: the changeover portion of jacket-type marine wind electric field foundation structure, comprise central post, crossbeam and supporting leg, described crossbeam one end is arranged on described central post side, and described supporting leg is arranged on the described crossbeam other end.
Further: described crossbeam has 4.
Further: described supporting leg has 4, described supporting leg is cylindrical.
The utility model has the advantage of and adopt integral transition segment structure, eliminate the shortcoming of stress high concentration, the Rigidity and strength configuration of structure rationally, rate of utilization of strength is high, avoid fatigue damage concentrations, instead of traditional split design, improve the fatigue life of structure.
Accompanying drawing explanation
Fig. 1 the utility model overall structure schematic diagram.
Detailed description of the invention
The changeover portion of jacket-type marine wind electric field foundation structure, as shown in Figure 1, comprise central post 1, crossbeam 2 and supporting leg 3, described crossbeam 2 one end is arranged on described central post 1 side, described supporting leg 3 is arranged on described crossbeam 2 other end, described crossbeam 2 has 4, and described supporting leg 3 has 4, and described supporting leg 3 is cylindrical, adopt integral transition segment structure, reasonably be configured with the Rigidity and strength of structure, the utilization rate of the strength of materials significantly improves, and avoids the phenomenon that stress is too concentrated.
