Description

A kind of middle-size and small-size wind-driven generator modularity ground

Technical field

This utility model is related to electrical equipment technical field, and more particularly, to one kind is applied in all kinds of landform and Different climate Under the conditions of install middle-size and small-size wind-driven generator modularity ground.

Background technology

3 stages be experienced on China, foundation of wind-driven generator unit design overall.First stage is before 2003, Single-machine capacity is little, and foundation of wind-driven generator unit mainly entrusts exploration and design unit to complete by domestic owner or manufacturer, the master of design Will be according to the code for foundation for Building class.Second stage is 2003-2007, belongs to introduction and digestion phase.External MW class Wind power generating set starts to introduce on a large scale China, most of basic engineering be all according to manufacturer propose with reference to figure, domestic set Meter institute is designed adjustment according to the concrete condition of wind energy turbine set geological exploration data and domestic construction material, finally by foreign vendor Meet confirmation.2007 is the phase III later, belongs to the autonomous Design stage of MW class crew base.China was in 2007 9 The moon has promulgated FD003-2007《Wind power generating set Base foundation design specifies》, and the same period be proposed supporting design software.

FD003-2007《Wind power generating set Base foundation design specifies》In consider square spread foundation, square cushion cap Pile foundation, and Rock Bolt Foundation.In addition to square foundation, conventional also have circular, octagon spread foundation and circle, eight Side shape pile foundation of bearing platform plinth.From when should be according to building place foundation condition and wind power generating set superstructure to basic requirement Determine, need if necessary to be calculated or technology and economy comparison, when foundation soil is for soft layer or high-compressibility soil layer, preferably preferentially Using pile foundation.For tower foundation, circular enlargement is basic and concrete works amount of square spread foundation will be sufficiently close to.

Traditional ground long construction period, concrete amount are big, reinforcing bar rolling is wasted time and energy, concrete is difficult vibration compacting Deng.After wind-driven generator End Of Service, the modularity ground of present example can be removed, and local environment will not be made Become pollution, the modularity ground after dismounting is through after the assay was approved, applying in next project and substantially reduce investment Return period, decrease the destruction to environment simultaneously.

Content of the invention

The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of middle-size and small-size wind-power electricity generation Machine modularity ground.

This utility model solves its technical problem and be employed technical scheme comprise that：

A kind of middle-size and small-size wind-driven generator modularity ground, including foundation body it is characterised in that：Described foundation body Including polygonal base, crossbeam, longeron and base plate, polygonal base, crossbeam, longeron are all fixedly installed on base plate, polygon Basis is located in the middle part of base plate, and longeron is arranged on radial even structure distribution outside polygonal base, and crossbeam is located at adjacent Between longeron and crossbeam two ends are connected with corresponding longeron respectively, and described polygonal base, crossbeam, longeron and base plate are equal Using Q345 steel, Q345 steel surface is provided with glass fiber compound material protective layer.

Described longeron inner and polygonal base surface between, between longeron bottom and backplate surface, crossbeam two ends with Between longeron outer end, between crossbeam bottom and base plate, all it is bolted fixation.

In sum, this utility model has the advantages that：

1st, polygonal base ring and cement bed course pass through bolt leveling, fixation, and foundation body adopts Q345 steel, and outside is adopted Use glass fiber compound material protective layer, both ensure that rigidity, the intensity of material, can guarantee that the anti-corrosive properties of polygonal base ring again Energy.

2nd, this patent polygonal base ring will be connected between polygonal base, crossbeam, longeron and base plate, no by bolt Reinforcing bar rolling and process of binding, no concrete vibrating process, no concrete curing process.

3rd, after the completion of polygonal base, crossbeam, longeron and base plate connect, covered by soil layer and tamp, to resist wind-force The moment of flexure of electromotor.

4th, only need to 4-5 people in installation process, coordinate 5 tons of cranes, construction period just can complete entirely for about 10-15 days The construction of ground, improves work efficiency in 30-40 days that compare traditional ground.

5th, after wind-driven generator End Of Service, the modularity ground of present example can be removed, will not be to locality Environment, the modularity ground after dismounting is big through after the assay was approved, can also applying in next project Shorten greatly and invest return period, decrease the destruction to environment simultaneously.

6th, this middle-size and small-size wind-driven generator modularity ground had both remained the advantage on traditional wind basis, made simultaneously Valency is cheap, does not have loaded down with trivial details reinforcing bar binding engineering, and speed of application is fast.

7th, when wind-driven generator because addressing error or certain reason need in not up to wind power generating set service life When wind power generating set is moved, it is to avoid the secondary input of wind power generating set ground cost.
