Abstract
The invention discloses a plate support structure for a tower and a foundation of a wind generator. A conical or pyramidal shape is formed by connecting cambered or conical diagonal brace plates in a surrounding manner and supports the tower and a guide tube frame transition part, line-surface contact area is increased, and accordingly stress concentration is avoided. By fully taking the advantage of fine spatial load-transmitting performance of the conical or pyramidal shape, the support structure high in bearing capacity and rigidity can be formed at low component thickness. The weight and manufacturing cost of the foundation are reduced by the aid of the structural design. In addition, the conical or pyramidal structure formed by the cambered or conical plates can provide sufficient space for holding electric devices of wind generators, and can provide temporary shelter for staff maintaining the wind generators to facilitate operation for the maintenance staff.
Description
[technical field]
The present invention relates to a kind of changeover portion linkage structure, the plate type support structure on especially 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 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 present invention namely proposes for this Study on Problems.
[summary of the invention]
The technical problem to be solved in the present invention 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 plate type support structure on a kind of wind-driven generator tower of the present invention 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 present invention 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.
