Definitions

  • the subject of invention consists of a monopile foundation sunk into the bottom of a water area and designated for the purpose of fixing a wind power plant thereon.
  • a monopile foundation is commonly used in sea, offshore wind power farms, such as, for instance, the Horns Rev farm in Denmark, or the Burbo farm in the UK.
  • the Polish patent application no. P. 347733 features a wind turbine for electric power generation which has two rotors fixed firmly to the tower; the tower is placed on its foundation via bearings, thanks to which it may rotate, along with the rotors, perpendicularly to the wind direction, steered by a back rudder.
  • a disadvantage of such solutions consists in that, along with an increase in the rated power of a wind power plant, the force of the pressure exerted on the ground at the bottom of the water area where the monopile foundation is set increases as well, which, in turn, requires to increase the diameter of the foundation pile accordingly.
  • the monopile foundation of a contemporary wind power plant of output 5 MW requires a pile having a diameter of over 5 metres; hammering or drilling such a thick pile into the bottom involves large engineering difficulties.
  • the resistance plate has at its bottom side edges situated on the external and internal perimeter of the plate, the blades of which are directed downwards, at the angle from 10° to 50°.
  • the subject of invention is illustrated, as sample of performance, by a drawing presenting rotary-wise a monopile foundation in an axial section.
  • the monopile foundation sunk into the bottom of a water area and designated to fix a wind power plant thereon includes a foundation pile 1 , a resistance plate surrounding it 2 , placed on the water area bottom, and gravel or other loose and hard material 4 , put into the space between the external surface of the foundation pile and the internal surface of the resistance plate, which elements co-operate with each other.
  • the resistance plate has at its bottom side edges 3 , situated on the external and internal perimeter of the plate, the blades of which are directed downwards, at the angle from 10° to 50°.
  • the co-operation of individual elements of the device as per invention consists in that the pressure force of the wind on the wind turbine rotor causes reaction forces exerting pressure on the foundation.
  • reaction forces consist in cutting forces in the ground around the foundation pile
  • second part of these reaction forces consist in friction force at the junction of the surface of the water area bottom with the bottom side of the resistance plate.
  • the volume of such friction force depends on the weight of the resistance plate and a degree of roughness of its bottom part.
  • the resistance plate be made of heavy concrete the mass density of which is at least 3 g/cm 3 .
  • a layer of gravel or other loose and hard material put into the space between the external surface of the foundation pile and the internal surface of the resistance plate ring is to transfer the horizontal force from the foundation pile to the resistance plate and, on the other hand, to ensure free settlement of the resistance plate on the bottom.
  • a considerable advantage of the invention consists in the possibility to apply a shorter monopile foundation of length equal to approximately one and a half of the height of the resistance plate, because the arm of the bending moment is reduced and at the same time the land around the monopile foundation gets denser, allowing to carry larger cutting forces.
  • Another large advantage of the invention consists in the possibility to apply a single pillar foundation of smaller diameter in the case of a shallow water area, allowing to save on steel consumption.
