Problems solved by technology

However, there are three types of existing floating foundations: semi-submersible, TLP and Spar. Compared with traditional fixed foundations, floating foundations are larger in size, less stable, and more difficult to construct and install. Larger, higher cost, difficult to popularize and apply, it is urgent to reduce the cost of floating wind turbines

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] like figure 1 A new type of floating fan foundation shown includes a foundation 3, a tower 2 arranged on the foundation 3, a blower 1 arranged on the tower 2 and a mooring system. The mooring system includes a fixed ring 5 and several rings arranged on the fixed ring. The mooring cables 6 around the ring 5, the fixed ring 5 is a hoop structure, which is detachably sleeved on the tower 2 and supported on the foundation 3 or the tower 2, and the mooring cables 6 are used for anchoring with the seabed surface.

[0025] Specifically, the fan 1 is arranged on the top of the tower 2, the top of the foundation 3 is connected to the bottom of the tower 2, the bottom of the foundation 3 is provided with a water turbine 4, the impeller of the fan 1 and the impeller of the water turbine 4 are in the same direction, and the water turbine 4 can follow the tower. 2 rotate to...

Abstract

A novel floating type draught fan foundation comprises a foundation body, a tower tube arranged on the foundation body, a draught fan arranged on the tower tube and an anchoring system, the anchoring system comprises a fixing ring and a plurality of mooring cables annularly distributed on the periphery of the fixing ring, and the fixing ring is of a hoop structure, detachably connected to the tower tube in a sleeving mode and supported on the foundation body or the tower tube. The mooring cable is used for being anchored to the seabed surface. The fan foundation further comprises a water turbine located at the bottom of the foundation, the fan impeller and the water turbine impeller face the same direction, and the water turbine can rotate along with the tower drum. The whole fan is separated from the mooring system, and matching is easy and convenient. The mooring system can be installed in advance, then the whole fan is transported to the site to be matched with installation of the mooring system, the long-time construction operation of whole machine installation is decomposed, the utilization rate of the short-time construction window period on the sea is increased, the ship dispatching difficulty is reduced, the construction efficiency is improved, and the cost is correspondingly reduced.

Description

technical field [0001] The invention belongs to the technical field of offshore wind power foundations, and in particular relates to a novel floating wind turbine foundation. Background technique [0002] In recent years, as the development of onshore and offshore wind power resources has gradually become saturated, the development of deep-sea wind power has become the trend of future wind power development. Due to the large water depth, fixed foundations are no longer suitable for deep-sea wind farms, and floating foundations are an inevitable choice. However, there are three types of existing floating foundations: semi-submersible, TLP and Spar. Compared with traditional fixed foundations, floating foundations are larger in size, less stable, and more difficult to construct and install. Larger, higher cost, and difficult to popularize and apply, it is urgent to reduce the cost of floating wind turbines. [0003] Based on this, the present invention proposes a new type of...
