Abstract
The invention relates to a wind power generation power foundation, in particular to a square pressure-bearing grid-embedded wind power generation power foundation of a wind power generating set. In the wind power generation power foundation, a cantilever beam is arranged underground; a concrete cushion is arranged below the cantilever beam and is provided with a foundation bottom board; the center of the foundation bottom board is provided with a hollow metallic bottom board; the metallic bottom board is embedded into the concrete cushion and is provided with a truss bolt; the truss bolt is fixed with a drum body on the bottom of a foundation flange; the cantilever beam is inserted into the foundation flange; and reinforcing steel bars with a cross structure are arranged between the cantilever beam and the foundation bottom board. The square pressure-bearing grid-embedded wind power generation power foundation has the advantages that compression resistance and anti-bending strength of the wind power generation power foundation are increased greatly; moreover, the foundation reduces man-hour costs, shortens installation time, and plays an important role in realizing quick grid-connected power generation of the wind power generating set.
Description
Technical field
The present invention relates to a kind of generation power foundation of wind power, relate in particular to the square pressure-bearing grid-embedded generation power foundation of wind power of a kind of wind-powered electricity generation unit.
Background technology
Wind power generation stepped in basic conventional method on the hard foundation soil be to adopt the grillage beam type basis, its structure as shown in Figure 1, this kind structure design is imbedded in the bar construction by crab-bolt, semi girder and base center tube and is formed.This basic constructional design has stronger anti-pressure ability.But this design does not have stronger bending resistance apart from ability, occurring under the abominable situation such as high wind, and this generation power foundation of wind power, because crab-bolt is suspended in the base center tube, barrel and reinforcing bar do not link together fully.Therefore can not bear bigger bending moment, cause the bigger waste of basic engineering.The security reliability of tower tube can not guarantee.
Summary of the invention
The invention provides the square pressure-bearing grid-embedded generation power foundation of wind power of a kind of wind-powered electricity generation unit for solving the problems of the technologies described above, purpose is the compressive property that has increased generation power foundation of wind power, strengthens anti-bending strength simultaneously, reduces cost, shortens installation period.
For reaching the square pressure-bearing grid-embedded generation power foundation of wind power of above-mentioned purpose wind-powered electricity generation unit of the present invention, be provided with semi girder below ground, below semi girder, be provided with concrete cushion, on concrete cushion, be provided with sole plate, be provided with the metal base plate of hollow at the center of sole plate, metal base plate is embedded in the concrete cushion, metal base plate is provided with crab-bolt, the cylindrical shell of crab-bolt and basic flange bottom is fixed, semi girder is inserted in the basic flange, is provided with well minor structure reinforcing bar between semi girder and the sole plate.
The outside of described basic flange and semi girder junction is provided with the top stiffener.
Described concrete cushion is square.
The bottom of described crab-bolt is fixed on the concrete cushion, and crab-bolt forms annulus on metal base plate.
It is radial that described semi girder becomes on basic flange.
The described semi girder that is inserted in the basic flange is connected with the embedding reinforcing bar.
Advantageous effect of the present invention: the bottom surface on basis of the present invention is connected with square planar ground on every side, has increased basic lifting surface area, and lifting surface area has equably distributed.So that the basis can be born from the wind power generating set compressive stress, the pressure on the basic compression area has increased, and can be used for resisting from the moment of flexure of superstructure varying environment and the pull out force on the basis, bottom surface that causes.Not only increase the compressive property of generation power foundation of wind power, also strengthened anti-bending strength simultaneously greatly.The present invention is with semi girder Embedded structure, reduced the construction inconvenience that adopts girder structure in the past and brought, the many disadvantages that involves great expense.The present invention adopts basic flange to dock with the upper column barrel structure generation power foundation of wind power, in the generation power foundation of wind power construction and wind-driven generator can reduce the man hour of labour cost when installing, shorten installation period, generating plays an important role to the wind-driven generator rapid combination.
