Problems solved by technology
At present, wind farms are generally installed in the intertidal zone or near-shore areas, where the water depth is relatively shallow, and it is difficult for large ships to enter the site for construction
However, when the water depth is less than 2m, the existing traditional construction ships cannot enter the site for construction, which greatly limits the popularization and application of offshore wind turbines

Embodiment Construction
[0024] The specific implementation of the present invention will be described in detail below in conjunction with preferred embodiments.
[0025] see attached Figure 1-4 , compared with the prior art, the present invention provides a wind turbine assembly installation system in the offshore intertidal zone, including a working platform 1 and a crawler crane 8 to form a wind turbine construction system, and the working platform is composed of a truss structure welded horizontally and vertically , the area of the working platform is 2000~8000m 2 , the crawler crane moves on the working platform. The working platform can float on the sea for mobile stationing, and can also be directly located on the mud surface of the beach for construction work. The middle part of the working platform is equipped with a crawler crane fixing device (Fig. not shown), the fixing device plays the role of indicating the parking position of the crawler crane and fixing it. In the floating state, ...

The invention relates to an installation system and construction method of a wind turbine assembly in a sea intertidal zone. The installation system comprises an operation platform and a crawling crane, wherein the operation platform can float, move and be docked on the sea and can also be set on a muddy surface of a beach to carry out construction operation. The construction method includes the steps that when a tide rises, the operation platform is moved and docked through a tug, and a pile transporting boat is docked; when the tide falls, the operation platform is set on the beach, and steel pipe piles are craned by the crawling crane to sink; when the tide rises, the operation platform is moved and docked, and the pile transporting boat carries wind turbine equipment and then is berthed; when the tide falls, the operation platform is set on the beach, and the whole wind turbine assembly is craned by the crawling crane to be installed. The installation system and construction method of the wind turbine assembly in the sea intertidal zone have the advantages that the operation platform does not need to be leveled by adding ballast water when in a floating state, and the depth of immersion is smaller than 1.6m; the operation platform can be set on the muddy surface of the beach to carry out construction, and the 1000t crawling crane is carried by the operation platform and can move on the operation platform and be used for large-diameter steel pipe pile sinking operation and wind turbine separate installation; the problem that large ships can not run into a shallow intertidal zone to carry out construction is solved.
Description
technical field [0001] The invention belongs to offshore construction methods, in particular to a fan assembly installation system in the intertidal zone of the sea and a construction method thereof. Background technique [0002] Due to the combined effects of strong wind loads, wave impact loads, current loads, and seawater corrosion, the construction of wind turbines in offshore wind farms is far more technically difficult than on land, with complex structures and high costs. [0003] At present, the foundation types of offshore wind turbines mainly include: gravity foundation, monopile foundation, tripod foundation, jacket foundation and floating foundation. Among them, the single-pile foundation has the advantages of simple manufacture, no need to tidy up the seabed, strong adaptability to terrain, and fast construction, and is most widely used in wind turbine foundations. This type of foundation adopts large-diameter steel pipe piles with a diameter of 3 to 5m. After t...
