Abstract

The utility model discloses a plate type connecting structure of a wind driven generator tower and a foundation. Inclined supporting plates which are cambered-surface plates or cone-shaped plates are connected to enclose a cone-shaped or pyramid-shaped structure, supporting is provided for a transition section of the tower and a conduit frame, and line-surface contact is increased so that a phenomenon of stress concentration is avoided. Good space force-transferring properties of the cone-shaped or pyramid-shaped structure are sufficiently used. A supporting structure with high carrying capacity and large rigidity can be formed by small thicknesses of components. According to the structural design, weight of the foundation is lightened, manufacturing cost of the foundation is reduced, and meanwhile sufficient space can be provided by the cone-shaped or pyramid-shaped structure which is formed by the cambered-surface plates or the cone-shaped plates. The space can be used for placing wind driven generator electrical equipment and providing a temporary shelter for maintenance personnel of a wind driven generator, and therefore the maintenance personnel can conduct work conveniently.

[background technique]
Along with Oversea wind power generation, the especially fast development of the marine wind field of high-power wind-driven generator and deep water, jacket is lightweight, and easy transportation and installation are adopted by increasing marine wind field.Since long-term fatigue load, the key that has been designed to this linkage structure of the linkage section of wind-driven generator tower and jacket frame foundation structure.In wind-driven generator jacket basic design process, the supported design of tower cylinder changeover portion often adopts column diagonal brace or gusset to support to transmit side direction moment of flexure and lateral load.In practical engineering application, because the cross section of column diagonal brace and gusset is much smaller than tower cylinder changeover portion cross section, the contact of its face is more, and this design can cause the stress concentration phenomenon usually, produces easily under the effect of stormy waves and destroys.The utility model namely proposes for this Study on Problems.
[model utility content]
The technical problems to be solved in the utility model provides a kind of tilt prop that adopts cambered plate or conical plate face and connects and surround taper shape or pyramid shape, for tower cylinder and jacket changeover portion provide support, increase wire attachment, to avoid the stress concentration phenomenon, take full advantage of the good space transmission force property of taper shape or pyramid shape, can form the supporting structure that bearing capacity is high, rigidity is large with less member thickness.
For solving the problems of the technologies described above, the board-like linkage structure on a kind of wind-driven generator tower of the utility model and basis, comprise base carrier, described base carrier comprises some pile legs, described spud leg upper end is provided with connecting platform, described connecting platform is provided with tilt prop, described tilt prop connects into up-narrow and down-wide taper, utilize cone structure, make the stressed connecting platform that evenly is delivered to of tilt prop, described tilt prop upper end is connected with tower cylinder changeover portion, and described tower cylinder changeover portion bottom extends to platform and is connected, and increases join strength.
Described tilt prop is cambered plate, and described cambered plate connects and composes taper shape, and described taper shape is one-body molded.Described tilt prop also can be conical plate, the pyramid shape that described conical plate connects and composes.The External Force Acting that the tower cylinder is subject to is delivered to base carrier by cambered plate or conical plate equably, effectively avoids the stress concentration phenomenon.Simultaneously, the taper shape or the pyramid-shaped structures that are made of cambered plate or conical plate can provide enough spaces, can supply to place the wind-driven generator electric equipment, and for the attendant of wind-driven generator provides temporary shelter, carry out operation to maintain easily personnel.
Described tower cylinder changeover portion comprises cylindrical connecting tube, and described connecting tube inner wall surrounding is provided with stiffening rib, and described connecting tube bottom is connected with connecting platform.
Described base carrier forms the cone structure that is up-narrow and down-wide by spud leg, and described spud leg is by the mutual interconnection of diagonal brace.According to the needs of join strength, the quantity of spud leg is some, and described base carrier comprises the base carrier that is comprised of three or four pile legs.
The utility model adopts the tilt prop of cambered plate or conical plate to connect and surrounds taper shape or pyramid shape, for tower cylinder and jacket changeover portion provide support, increase the contact of line face, to avoid the stress concentration phenomenon, take full advantage of the good space transmission force property of taper shape or pyramid shape, can form the supporting structure that bearing capacity is high, rigidity is large with less member thickness.This structural design has alleviated basis weight, reduces foundation cost; Simultaneously, the taper shape or the pyramid-shaped structures that are made of cambered plate or conical plate can provide enough spaces, can supply to place the wind-driven generator electric equipment, and for the attendant of wind-driven generator provides temporary shelter, carry out operation to maintain easily personnel.
