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 meet the exploitation of wind energy on the sea, the especially exploitation of deep-sea wind field.Powerful wind-driven generator becomes development trend, its impeller diameter is large, tower cylinder is high, wind-driven generator weight is large, consider that wind-driven generator needs to be arranged on the geographic area of high wind, the structure that the tower cylinder of wind-driven generator is connected with jacket basis is sufficiently firm, to resist normally and to act on the power on wind-driven generator under extreme operating condition; Especially the reliability ensureing that tower cylinder is connected with jacket linkage section is needed.
In wind-driven generator normally works, larger dynamic load is produced bottom towering tower cylinder, the dynamic load that its amplitude produces much larger than wave this structure, therefore emphasis is needed to consider its fatigue problem in this structural design, what make wind-driven generator tower and jacket foundation connection structure is designed in order to Focal point and difficult point, and namely the present invention 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 for the tower cylinder of offshore wind power equipment and the linkage structure of jacket, mainly comprising central seat component, tilt prop and bracket, in Mongolian pouch-type linkage structure, also comprise lateral bolster fagging.Have and connect reliably, the feature of good anti-fatigue performance.
Described central seat is connected with tower cylinder and puts by its circumferential hoop winding and the tilt prop be connected with platform surface is connected to jacket pylon portion.The central seat pipe circumference be connected with tower cylinder adopts cambered plate or conical plate as tilt prop, is provided with the bracket be connected with central seat and jacket platform surface in adjacent tilt prop jointing place.The bottom of described bracket is connected with platform surface, increases the area of contact that between tower cylinder and platform, power is transmitted, decreases stress and concentrate the generation with focus stress phenomena.
In Mongolian pouch-type linkage structure, described tilt prop is cambered plate, be connected on jacket platform by lateral bolster fagging bottom described tilt prop, described tilt prop is connected in Mongolian pouch-type around central seat pipe with lateral bolster fagging, and described lateral bolster fagging enhances the connection of tilt prop and platform.
In pyramid linkage structure, described tilt prop is conical plate, and described tilt prop connects in pyramid around central seat pipe, and this structure increases the connection area of tilt prop and platform and central seat pipe, suffered external force is uniformly distributed, avoids the phenomenon generation that stress is concentrated.
Be connected with cross one another hound between described two adjacent supporting foots, increase the stability of jacket.
The separate space that described tilt prop and bracket can be formed, for arranging electromechanical equipment, and the place be temporarily stationed of attendant.
Bracket bears a part passes to platform load from tower cylinder, increases and arranges bracket, suitably can reduce the thickness of tilt prop, alleviate the overall weight of structure.Bracket quantity is arranged according to practice of construction situation, and comprising is 3,4,6, or other quantity arranged 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, adopts cambered plate or conical plate as tilt prop, be provided with the bracket be connected with central seat pipe in adjacent tilt prop joint in the central seat pipe circumference be connected with tower cylinder.It is reliable that this structure has connection, the feature of good anti-fatigue performance.
