Problems solved by technology
According to different modes of transportation, wind turbine foundations are usually divided into non-towable and towable wind turbine foundations; compared with towable wind turbine foundations, non-towable wind turbine foundations have a larger dead weight and volume, and generally can only be hoisted during construction method, there are defects such as difficult construction, poor safety and high cost
However, the existing towable wind power foundation needs special equipment to assist floating in the transportation link, and is easily affected by ocean currents after being fixed.

The invention discloses an onshore wind power generating unit foundation. The onshore wind power generating unit foundation is provided with multiple landing legs and tightly-embedding columns. The landing legs and the tightly-embedding columns are of a hollow structure. Due to smaller dead weight, in the installation process, the onshore wind power generating unit foundation can be consigned to a predetermined sea area in a towing mode, and therefore the transportation difficulty is lowered; after installation, the tightly-embedding columns are tightly embedded into a sea bed, firmer positioning can be achieved, the influences of ocean current on the onshore wind power generating unit foundation are reduced, and then the onshore wind power generating unit foundation can be suitable for sea areas with different geological conditions and sea conditions. The invention further discloses an offshore wind power generating unit and an installation method of the onshore wind power generating unit foundation.
Description
technical field [0001] The invention relates to the manufacturing technology of offshore wind turbines, in particular to an offshore wind turbine foundation and an installation method thereof. Background technique [0002] With the development of society, the demand for energy is increasing; with the consumption of non-renewable energy such as oil and natural gas and the enhancement of people's awareness of environmental protection, clean energy is developing rapidly in countries all over the world, and wind power, as a clean energy, is becoming more and more popular among people. attention. [0003] Offshore wind turbines (referred to as offshore wind turbines or offshore wind turbines) are a new type of power generation equipment that utilizes offshore wind resources to generate electricity. On the foundation, the tower head is installed on the top of the tower; the foundation is set on the seabed to support and fix the tower, and the foundation plays a vital role in the ...
