Description
[technical field]
The utility model patent relates to the fish plate linkage structure on a kind of wind-driven generator tower and basis.
[background technique]
Along with Oversea wind power generation, the especially fast development of the marine wind field of high-power blower and deep water, offshore wind turbine jacket basis is because lightweight, and easy transportation and installation are adopted by increasing marine wind field.
Because long-term fatigue load, the linkage section of blower fan tower barrel and jacket frame foundation structure have been designed to key point and the difficult point of this structural type design.Owing to adopting the column diagonal brace when existing common blower fan jacket basis is connected with tower cylinder changeover portion, make the column diagonal brace bear lateral force and side direction moment of flexure, the stress of column diagonal brace is pressurized.By geometrical shape and the material behavior of column diagonal brace, short, maintenance difficult in working life, high cost problem can appear.
[model utility content]
The purpose of this utility model provides a kind of lightweight, long service life, cost is low, structural strength is large wind-driven generator tower changeover portion and jacket basis fish plate stay bolt linkage structure.
For above-mentioned purpose, the utility model by the following technical solutions:
The fish plate linkage structure on a kind of wind-driven generator tower and basis, it is characterized in that including jacket basis 1 and the columniform tower cylinder changeover portion 2 that props up on jacket basic platform 6, be provided with many fish plate stay bolts 3 on jacket basis 1, each root fish plate stay bolt 3 corresponding cylindrical outer surface with tower cylinder changeover portion 2 is fixedly connected with.
The fish plate linkage structure on aforesaid a kind of wind-driven generator tower and basis, it is characterized in that described fish plate stay bolt 3 is comprised of the fish tail shape arc plate 31 on top and the cylindrical tube 32 of bottom, described fish tail shape arc plate 31 upper end portions are fixedly connected with the cylindrical outer surface of tower cylinder changeover portion 2, and the bottom of cylindrical tube 32 is fixedly connected with jacket basis 1.
The fish plate linkage structure on aforesaid a kind of wind-driven generator tower and basis, it is characterized in that described fish plate stay bolt 3 has four, described jacket basis 1 includes four pile legs 11, and the bottom of the cylindrical tube 32 of described each root fish plate stay bolt 3 is connected with corresponding head with each pile leg 11.
The fish plate linkage structure on aforesaid a kind of wind-driven generator tower and basis is characterized in that being arranged with the stiffening ring 4 that increases tensile strength at the head of described spud leg 11.
The fish plate linkage structure on aforesaid a kind of wind-driven generator tower and basis is characterized in that being provided with the stiffening plate 5 that increases tensile strength between described fish plate stay bolt 3 and jacket basic platform 6.
The beneficial effect of the utility model patent has:
The utility model patent specifically adopts the pressurized column diagonal brace in the alternative common blower fan jacket basis of fish plate stay bolt.The difference of fish plate stay bolt and common column diagonal brace is, adopts the design of fish tail shape arc plate with cross section, tower cylinder changeover portion attachment portion, and the other end adopts the cylindrical tube design, and its main force-bearing characteristics is tension.
This design has effectively reduced the stress concentration phenomenon, and tower cylinder changeover portion is had reinforing function.Because the fish plate mechanical characteristic is tension, compares with traditional pressurized diagonal brace and can effectively reduce the diagonal brace wall thickness.The designed Placement of the utility model is utilized large, the lightweight characteristic of fish plate structural strength, can effectively reduce weight and the cost on jacket basis.

[embodiment]
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated:
As shown in the figure, the fish plate linkage structure on a kind of wind-driven generator tower and basis includes jacket basis 1 and jacket basic platform 6, is provided with columniform tower cylinder changeover portion 2 at jacket basic platform 6.Be provided with many fish plate stay bolts 3 on jacket basis 1.Each fish plate stay bolt 3 corresponding cylindrical outer surface with tower cylinder changeover portion 2 is fixedly connected with.
Furthermore, described fish plate stay bolt 3 is comprised of the fish tail shape arc plate 31 on top and the cylindrical tube 32 of bottom.Described fish tail shape arc plate 31 upper end portions are fixedly connected with the cylindrical outer surface of tower cylinder changeover portion 2, and the bottom of cylindrical tube 32 is fixedly connected with jacket basis 1.With tower cylinder changeover portion attachment portion, adopt the board-like connection of fish tail, namely fish tail shape arc plate 31 is connected with tower cylinder changeover portion.This Placement can be attached thereto with the closed curve that tower cylinder changeover portion cylndrical surface fits tightly by one section and connect, and has effectively increased diagonal brace and has contacted with the line face of tower cylinder changeover portion and reduce stress and concentrate.And the Placement of this fish plate and tower cylinder changeover portion has been equivalent in tower cylinder changeover portion outer installment the reinforcement structure, can improve structural strength and the bearing capacity of upper column cylinder changeover portion.
Described fish plate stay bolt 3 has four, and described jacket basis 1 includes four pile legs 11, and the bottom of the cylindrical tube 32 of described each root fish plate stay bolt 3 is connected with corresponding head with each pile leg 11.Cylindrical tube 32 bottoms of fish plate stay bolt directly are connected with jacket spud leg 11 heads, lateral load directly can be passed to the spud leg of main force support structure.In total, the main stress form of fish plate stay bolt is tension, has effectively avoided ever-present buckling problem in the common pressurized diagonal brace, therefore can prolong the working life of stay bolt, and can reduce fish plate stay bolt wall thickness.This design not only can reduce stress concentrates but also can reduce the inner stiffening rib quantity of tower cylinder, reduces foundation cost thereby alleviate structure weight.
As the optimal way of the present embodiment, being arranged with at the head of described spud leg 11 increases stiffening ring 4.Between the platform on described fish plate stay bolt 3 and jacket basis, be provided with stiffening plate 5.The major function of this linkage structure is to bear wind load, the caused lateral force of top blower fan gravity load and side direction moment of flexure.Load acts on tower cylinder changeover portion by the tower cylinder, is passed to jacket basic platform 6 and spud leg 11 ends via the fish plate stay bolt.Because upper load directly acts on the spud leg end by the transmission of fish plate stay bolt, therefore at pile crown position design stiffening ring 4 and between fish plate and platform, add stiffening plate 5, in order to increase the tensile strength of 6 on fish plate diagonal brace bottom and spud leg end, platform.
