Abstract
The invention discloses a connection structure for a stepped drum and a jacket of offshore wind power equipment. The connection structure mainly comprises a central base element, inclined strut plates and toggle plates. The ger-type connection structure further comprises lateral support plates; arc plates or tapered plates are arranged on the circumference of a central base pipe which is connected with the stepped drum, and serve as the inclined strut plates; and a toggle plate connected with the central base pipe is arranged at the joint of each two adjacent inclined strut plates. The connection structure is reliable in connection and favorable in fatigue resistance.
Description
[technical field]
The present invention relates to a kind of linkage structure, especially a kind of for the tower cylinder of offshore wind power equipment and the linkage structure of jacket
[background technique]
In order to satisfy the development and use of wind energy on the sea, the especially development and use of deep-sea wind field.Powerful wind-driven generator becomes development trend, its impeller diameter is large, the tower cylinder is high, wind-driven generator weight is large, consider that wind-driven generator need to be arranged on the geographic area of high wind, the structure that the tower cylinder of wind-driven generator is connected with the jacket basis must be enough firm, to resist the power that acts under normal and the extreme operating condition on the wind-driven generator; Especially need the reliability that guarantees that the tower cylinder is connected with the jacket linkage section.
In the wind-driven generator normal operation, towering tower cylinder bottom produces larger dynamic load, its amplitude is much larger than the dynamic load of wave to this structure generation, therefore need emphasis to consider its fatigue problem in this structural design, make being designed to for Focal point and difficult point of wind-driven generator tower and jacket foundation connection structure, the present invention namely proposes for this Study on Problems.
[summary of the invention]
For solving the problems of the technologies described above, the invention provides a kind of novel tower cylinder that is used for offshore wind power equipment and the linkage structure of jacket, mainly comprise the central seat member, tilt prop and bracket in yurt type linkage structure, also comprise the lateral bolster fagging.Have and connect reliably the characteristics of good anti-fatigue performance.
Described central seat and tower cylinder link to each other and put and the tilt prop that is connected with platform surface is connected to jacket pylon section by its circumferential hoop winding.The central seat pipe that is connected with the tower cylinder circumferentially adopts cambered plate or conical plate as tilt prop, is provided with in adjacent tilt prop jointing place with central seat to be connected the bracket that is connected with jacket platform.The bottom of described bracket is connected with platform surface, increase the area of contact that power is transmitted between tower cylinder and the platform, has reduced that stress is concentrated and the generation of focus stress phenomena.
In yurt type linkage structure, described tilt prop is cambered plate, described tilt prop bottom is connected on the jacket platform by the lateral bolster fagging, and described tilt prop is connected around the central seat pipe with the lateral bolster fagging and is the yurt type, and described lateral bolster fagging has been strengthened tilt prop and is connected connection with platform.
In the pyramid linkage structure, described tilt prop is conical plate, and described tilt prop connects around the central seat pipe and is pyramid, and this structure has increased the connection area of tilt prop and platform and central seat pipe, suffered external force is evenly distributed, and the phenomenon of having avoided stress to concentrate produces.
Be connected with cross one another hound between the described two adjacent supporting foots, increase the stability of jacket.
The separate space that described tilt prop and bracket can form is used for arranging electromechanical equipment, and attendant's the place of temporarily being stationed.
Bracket is born a part and is passed to the load of platform from the tower cylinder, increases bracket is set, and can suitably reduce the thickness of tilt prop, alleviates the overall weight of structure.Bracket quantity arranges according to the practice of construction situation, is included as 3,4,6, perhaps other quantity that arrange according to institute's connecting duct frame.
The present invention is a kind of for the tower cylinder of offshore wind power equipment and the linkage structure of jacket, circumferentially adopts cambered plate or conical plate as tilt prop at the central seat pipe that is connected with the tower cylinder, is provided with the bracket that is connected with the central seat pipe in adjacent tilt prop joint.It is reliable that this structure has connection, the characteristics of good anti-fatigue performance.
