Problems solved by technology
[0004] According to the current trend, the demand for wind power generators is gradually increasing due to the demand for power generation, so that the volume of wind power generators is getting larger and heavier, and the weight of the steel pipe piles used can reach 500 to 1,500 tons. Then it can reach 5 to 8 meters. If the installation operation of the wind-driven generator is to be completed, especially the suspension operation of the steel pipe pile, the crane disclosed in the aforementioned Japanese patent documents is in the form of a single boom. The structural strength of the boom must be quite high, resulting in a very high cost. Therefore, the unit responsible for installing wind turbines usually does not purchase such special equipment because of the demand for offshore installation of wind turbines. Even if it is leased, it will cost a lot of rent, so there is a need for improvement

Embodiment Construction
[0045] see Figure 1 to Figure 18 What is shown in the figure is the selected embodiment structure of the present invention, which is for illustration only, and is not limited by this structure in the patent application.
[0046] The invention provides a method for driving a steel pipe pile of an offshore wind power generator. Such as figure 1 As shown, the driving method 1 of the present invention includes sealing steel pipe piles 11, launching steel pipe piles 12, mounting and transporting steel pipe piles 13 at sea, platform fixing 14, lifting steel pipe piles 15, and striking steel pipe piles 16 And the step of base installation 17, the steel pipe pile 2 that wants to set up, as figure 2 The one shown is hollow and has openings 21 through both ends, and the steps are explained as follows:
[0047] Sealed steel pipe pile 11:
[0048] Such as figure 2 As shown, in this step, the steel pipe pile 2 is provided with end caps 22 and 23 at each opening 21 to seal the openi...

A driving method for a steel pipe pile of an offshore wind turbine comprises the following steps of: sealing the steel pipe pile, launching the steel pipe pile, carrying out offshore mounting and transporting on the steel pipe pile, fixing a platform, lifting the steel pipe pile, driving the steel pipe pile, mounting a foundation support and the like. The driving method replaces the known operation of transporting the steel pipe pile to a specified position by a floating crane and then carrying out driving and mounting, and also can complete the driving of the steel pipe pile under the condition of being arranged relatively smaller in size and relatively simpler in structure.
Description
technical field [0001] The invention relates to wind power generators, in particular to a method for driving steel pipe piles of offshore wind power generators. Background technique [0002] Existing wind generators mainly include a body, blades and columns, and are usually installed on the shore of the sea, and the blades are rotated by the sea breeze to make the body generate electricity and store energy. The other is to drive the steel pipe piles to the seabed, install a base on the sea surface that allows the columns to be fixed, and install the wind turbines offshore to obtain power generation with strong sea winds. advantages without taking up space available on land. [0003] For example, in the document of Japanese Patent Application Laid-Open No. 2006-37397, a construction method is disclosed in which a wind turbine is installed offshore and installed on the sea. There are mainly two working ships, one of which is larger in size and the other of which is larger in ...
