Abstract
The invention discloses a jacket cap structure for connecting a fan tower with a jacket foundation in offshore wind power. The jacket cap structure comprises a tower base serving as a downward extending part of the fan tower, a jacket cap upright post serving as an upward extension part of a jacket pile, a variable-section box beam for connecting the tower base and the jacket cap upright post, and a cross arm serving as a connecting structure between upright posts, wherein the variable-section box beam consists of an inner web, an outer web, an upper panel and a lower panel. The jacket cap structure is simple in structure, is reasonable in force transfer mechanism, is convenient to build, is easy to install, and is under small wind wave seepage pressure. The aims of simplifying the construction procedure, lowering the structural environment load and utilizing wind energy safely and reliably can be fulfilled.
Description
Technical field
Patent of the present invention relates to offshore wind farm construction applications, specifically, relate to a kind of when setting up ocean wind power facility for connecting the jacket cap structure on blower fan tower barrel and jacket basis.
Background technique
China is Oversea wind resource-rich country, and in the face of the energy demand that developed regions of bordering on the sea are vigorous, coastal waters wind-powered electricity generation has huge potentiality to be exploited.Along with reaching its maturity of offshore wind farm technology, high-power blower and deepwater field are future thrusts.The depth of water increase to 25m and after, traditional gravity type, single pile formula and three pile foundations will be no longer feasible gradually.And the depth of water darker than above-mentioned base form and larger blower fan can be competent in jacket-type basis, current most blower fan demand can be adapted to.
At present, the conventional joining method on blower fan tower barrel and jacket basis is gradual change tower cartridge type: tower cylinder lower end is tapered with the form of inverted conical, until the tubing of its diameter and jacket foundation is suitable, and be connected with main key pile by stull, diagonal brace, and jacket spud leg is as the main force transferring structure of jacket, then upper load is reached seabed further.Often gradual change is to b.s.l. in the lower end of gradual change tower barrel structure, and this can cause the increase of whole jacket basis wave current load to a certain extent; The existence of tower cylinder transition increases difficulty also can to installation scene.
Summary of the invention
In order to solve problems of the prior art, the invention provides a kind of jacket cap structure connecting blower fan tower barrel and jacket basis for offshore wind farm, solve the problem such as large wave loadings, stress complexity, in-site installation construction inconvenience that existing gradual change tower core structure faces.
The present invention is achieved by following technological scheme:
Connect the jacket cap structure on blower fan tower barrel and jacket basis for offshore wind farm, comprise the tower cylinder pedestal as blower fan tower barrel downward extension portion, described tower cylinder pedestal is connected with jacket cap column by variable cross-section box type beam.
Described jacket cap column is the upwards extension of jacket spud leg, between be provided with stull for linking jacket cap column.
Described variable cross-section box type beam is made up of endosternum, outer web, top plate and lower panel.
Described outer web, top plate, lower panel are connected in described jacket cap stud wall with the form of arc transition.
Described endosternum is attached on described tower cylinder pedestal and internal reinforcing structure thereof, and extends to described tower cylinder pedestal opposite side, connects with outer web described in this side.
The invention has the beneficial effects as follows:
The jacket cap structural safety of patent of the present invention is reliable, the ripe mounting type of offshore jacket platforms that what installation process adopted is: whole jacket cap structure can be cut out plate in advance in land formation field and welded manufacture, is transported to fabricating yard by barge; Jacket frame foundation structure complete piling work and cut flat expose spud leg after, namely rise and winch to by hanging ship the weld connection that flat spud leg and jacket cap column are carried out cutting in mounting point; After operation to be welded completes, blower fan tower barrel lifting is completed to jacket cap tower cylinder pedestal and connects.Whole jacket cap structure is all in more than highest water level after installation is complete, can not increase extra wave, current load to overall structure.
Therefore, patent structure simple structure of the present invention, power transmission mechanism rationally, be convenient to marine transportation and in-site installation operation, strong adaptability, the object simplifying constructing operation operation, avoid increase overall structure wave loadings can be reached.

Fig. 3 is three-dimensional half sectional view;
In figure: 1, jacket cap column; 2, stull; 3, tower cylinder pedestal; 4, endosternum; 5, outer web; 6, endosternum extension; 7, variable cross-section box type beam; 8, top plate; 9, lower panel.
Embodiment
For the content of patent of the present invention, feature and effect can be set forth further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
As shown in the figure, jacket cap structure of the present invention, tower cylinder pedestal 3 is the extension of blower fan tower barrel down to jacket cap structure, and its material external diameter wall thickness and internal reinforcing structure should be identical with selected blower fan tower barrel structure.Jacket cap column 1 be jacket spud leg upwards to the extension of jacket cap structure, its material external diameter wall thickness should be identical with put jacket basis spud leg.In variable cross-section box type beam 7 between jacket cap column 1 and tower cylinder pedestal 3: endosternum 4 is the main member of Transfer of Shear, outer web 5, top plate 8, lower panel 9 are the main member transmitting biaxial bending, moment of torsion, endosternum extension 6 enhances the integrity of structure, and strengthens the vulnerable area of top plate 8, lower panel 9; Above-mentioned endosternum 4, top plate 8, lower panel 9, outer web 5 be coupled to each other the stability enhancing each several part, the size that its concrete dimensional thickness also can be responsible for internal force according to it adjusts.Stull 2 directly connects with jacket cap column 1, links jacket cap column 1, plays the effect increasing structural redundancy.Outer web, top plate, lower panel reduce the sudden change of structure with the form of the arc transition form be connected in jacket cap stud wall, alleviate concentrating of stress.
Construction site completes the manufacture of jacket cap structure and is transported to fabricating yard by barge by land, jacket frame foundation structure complete piling and cut flat expose spud leg operation after, that can carry out jacket cap and jacket basis connects work.Jacket cap column 1 and jacket basis are cut flat spud leg and should be carried out weld connection, and blower fan tower barrel and jacket cap tower cylinder pedestal 3 part carry out Bolt Connection by flange.
Although be described the preferred embodiment of patent of the present invention by reference to the accompanying drawings above; but patent of the present invention is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under the enlightenment of patent of the present invention; do not departing under the ambit that patent aim of the present invention and claim protect, can also make the concrete conversion of a lot of form, these all belong within the protection domain of patent of the present invention.
