Embodiment 1

[0012] Such as figure 1 As shown, Embodiment 1 of the present invention provides an installation foundation assembly for offshore wind turbines. The installation foundation assembly includes a main pile 1 and at least one auxiliary pile 2 arranged around the main pile 1. Both the main pile 1 and the auxiliary pile 2 It is made of reinforced concrete. One end of the main pile 1 is placed in the seabed for fixing on the seabed, and the other end extends out of the sea level. The auxiliary pile 2 is set parallel to the main pile 1, and one end is placed in the seabed for fixing on the seabed. , the other end is placed below the sea level, so the auxiliary pile 2 is shorter than the main pile 1, and the auxiliary pile 2 can also be higher than the main pile 1 or equal to the main pile 1, which does not affect the use effect here. Pile 2 can meet the requirements, and can achieve the effect of use and save materials. The top of the main pile 1 is fixedly connected with a transition...

Embodiment 2

[0016] Such as image 3 Shown, on the basis of above-mentioned embodiment, auxiliary pile 2 is more than two (in this embodiment, be two, also can be many, can be adjusted according to geological situation and stressed situation, conduit and auxiliary pile are according to steel pipe inclination The number of braces is adjusted accordingly) and is arranged around the main pile 1, and a horizontal support rod is fixedly connected between the conduits 5 on the two adjacent auxiliary piles 2, preferably a horizontal support rod 7, which is used to enhance the level of the auxiliary pile 2. stiffness, thereby further enhancing the horizontal stiffness of the main pile 1. The horizontal support rods 7 are all made of metal material. Metal assembly weldments preset in the processing workshop such as Figure 4 As shown, the conduits 5 are respectively welded at one end of the two oblique support rods 6, the other ends of the two oblique support rods 6 are respectively welded on the...

Abstract

The invention provides an offshore wind turbine generator set installation fundamental assembly. The offshore wind turbine generator set installation fundamental assembly comprises a main pile and at least one auxiliary pile, wherein the auxiliary pile is parallel to the main pile. A transition segment is fixedly connected with the top of the main pile. A flange which is used for connecting a tower cylinder is installed on the top of the transition segment. The auxiliary pile is fixedly connected on a duct. An oblique supporting rod is fixedly connected between the transition segment and each duct. The offshore wind turbine generator set installation fundamental assembly solves the problems that construction difficulty is big, construction period is long and construction cost is high, wherein the problems are caused by the fact that pile diameter is too large, weight is too big and rigidity is small in high-power offshore wind turbine generator set single pile foundation. The offshore wind turbine generator set installation fundamental assembly exerts a mature design and construction experience of existing offshore wind unit single pile foundation.

Description

technical field [0001] The invention relates to a basic building technology for offshore equipment installation, in particular to a basic component for installing offshore wind turbines. Background technique [0002] Wind energy is a pollution-free renewable energy, inexhaustible and inexhaustible. With the demand for energy and the requirements of the ecological environment, the development of this new energy is being paid more and more attention by people. Land wind power has problems such as large area and noise pollution, while offshore wind energy, as a new form of wind energy, has the advantages of low turbulence intensity, stable dominant wind direction, saving land resources, stable wind energy, no noise and landscape pollution. Therefore, many countries with abundant offshore wind energy have begun to vigorously develop offshore wind power. As an important part of offshore wind farm construction, the basic components of wind turbines require advanced technology as...
