Abstract
The utility model discloses a multiangular frame foundation for an offshore wind power generator. The multiangular frame foundation comprises pile legs, pile leg sleeves and a multiangular frame. The pile legs are fixedly arranged in a seabed, the pile leg sleeves are arranged at the tops of the pile legs, and the pile legs are connected with the multiangular frame. The multiangular frame foundation for the offshore wind power generator solves the bottleneck of lacking of large-sized pile sinking equipment in development of offshore wind power generation, construction procedures are further optimized, and construction efficiency is improved.
Description
Technical field
The utility model relates to the basic engineering of offshore wind farm industry, relates in particular to polygonal basis of a kind of offshore wind farm blower fan.
Background technology
The intertidal zone is between the high and low tidal level of spring tide, the area that is submerged and exposes with tiding.According to preresearch estimates, the intertidal zone annual mean wind speed can reach the 6-7 meter per second, so possesses utilizable wind energy in the intertidal zone.For the intertidal belt wind electric engineering, it is mainly concerned with the construction on wind-powered electricity generation unit basis.
The maximum difference of Oversea wind power generation and land wind-power electricity generation is both residing positions; Because the basis of offshore wind farm unit is in the sea; Increased many extra load and uncertain factor, thereby design is comparatively complicated, form of structure is the variation owing to different sea situations also.What the fixed basis of offshore wind farm unit was the most frequently used has three kinds: single pile formula, gravity and triangle posture.Single pile formula basis is simple in structure and easy for installation because of it, is present commonplace form.But the pile sinking equipment that can implement large-scale large-diameter tubular pile at present is few, and acquisition cost is high, has therefore caused the inconvenience of pile sinking.
Therefore, need provide polygonal basis of a kind of offshore wind farm blower fan to address the above problem in the prior art.
The utility model content
In order to address this problem; The utility model discloses polygonal basis of a kind of offshore wind farm blower fan; Said polygonal basis comprises spud leg, spud leg sleeve and polygonal, and said spud leg is fixedly installed in the sea bed; Said spud leg sleeve is put the top at said spud leg, and said spud leg is connected with said polygonal.
Preferably, said polygonal is tripod.
Preferably, connect through grouting between said spud leg sleeve and the said spud leg.
Preferably, said polygonal comprises support body and center main cylinder, and said support body is connected on the main cylinder of said center.
Preferably, connect with support bar between said polygonal the said support body.
Preferably, the upper end of said center main cylinder is connected bottom pylon through bolt.
The offshore wind farm blower fan of the utility model polygonal basis solved the bottleneck that the offshore wind farm development lacks large-scale pile sinking equipment, also optimized working procedure simultaneously, improved construction efficiency.
In the utility model content part, introduced the notion of a series of reduced forms, this will further explain in specific embodiment part.The utility model content part does not also mean that key feature and the essential features that will attempt to limit technical scheme required for protection, does not more mean that the protection domain of attempting to confirm technical scheme required for protection.
Below in conjunction with accompanying drawing, specify the advantage and the characteristic of the utility model.
Description of drawings
Fig. 1 is the sketch map according to polygonal the basis of offshore wind farm blower fan of an embodiment of the utility model.
The specific embodiment
In the description hereinafter, provided a large amount of concrete details and the utility model has been understood more completely so that provide.Yet, it will be apparent to one skilled in the art that the utility model can need not one or more these details and be able to enforcement.In other example,, describe for technical characterictics more well known in the art for fear of obscuring with the utility model.
In order thoroughly to understand the utility model, detailed structure will be proposed in following description.Obviously, the execution of the utility model is not limited to the specific details that those skilled in the art has the knack of.The preferred embodiment of the utility model is described in detail as follows, yet except these were described in detail, the utility model can also have other embodiments.
Below in conjunction with accompanying drawing the embodiment of the utility model is done detailed description.
With reference to figure 1, be sketch map according to polygonal the basis of offshore wind farm blower fan of an embodiment of the utility model.Polygonal the basis of the utility model comprises spud leg 1, spud leg sleeve 2 with polygonal 3.Wherein spud leg 1 is fixedly installed in the sea bed 7.The spud leg 1 of three distributions triangular in shape can be set in the present embodiment.Spud leg sleeve 2 is arranged on the top of spud leg 1, and spud leg 2 is connected with polygonal 3.Polygonal in the present embodiment 3 is tripod.For example can be welded for polygonal 3 through steel pipe.
Can connect through grouting between spud leg sleeve 2 and the spud leg 1.
The steel pipe pile diameter that adopt on this spider basis can be less than the used steel pipe pile in single pile basis, on the complexity of construction equipment and difficulty of construction, is less than the basic piling construction of single pile.When construction, earlier a plurality of spud legs are squeezed into sea bed, make spider according to real size then, be transported to on-the-spot back leveling is installed; Also spider can be installed earlier, put again and break pile sinking.
The load distribution on polygonal the basis of the utility model is better than the single pile basis so plant base form aspect stable on the bigger ground surface of a plurality of attachment points and spider area.The spider basis is compared to single pile and the maximum advantage of gravity type foundation is before the basis is placed in darker marine site, to need not sea bed is flattened, for construction brings great convenience.
The offshore wind farm blower fan of the utility model polygonal basis solved the bottleneck that the offshore wind farm development lacks large-scale pile sinking equipment, also optimized working procedure simultaneously, improved construction efficiency.
The utility model is illustrated through the foregoing description, but should be understood that, the foregoing description just is used for for example and illustrative purposes, but not is intended to the utility model is limited in the described scope of embodiments.It will be understood by those skilled in the art that in addition; The utility model is not limited to the foregoing description; Instruction according to the utility model can also be made more kinds of variants and modifications, and these variants and modifications all drop in the utility model scope required for protection.The protection domain of the utility model is defined by appended claims book and equivalent scope thereof.
