Abstract

The utility model relates to the technical field of ocean engineering, and discloses an anchoring foundation and ocean engineering equipment. According to the anchoring foundation provided by the utility model, the anchor body is arranged in a mode that the anchor head is axially arranged at one end of the anchor body along the central axis of the anchor body, and the size of the anchor head is gradually reduced in the direction deviating from the anchor body, so that the cross-sectional area of the front end (the end far from the anchor body) of the anchor head is smaller than that of the rear end (the end close to the anchor body), and a wedge-like structure is formed. When the anchor body is in a submerged stage, the end part with smaller section size of the anchor head preferentially touches the seabed to form an initial penetration cut-in point, and the resistance of the anchor body penetrating the seabed is reduced, so that the anchor body is easier to break through the seabed under the action of dead weight, the difficulty of the anchor body in initial penetration of the anchor body into the seabed is obviously reduced, and the installation difficulty and construction cost of the anchor body are reduced.

Description

Anchor foundation and ocean engineering equipment Technical Field The utility model relates to the technical field of ocean engineering, in particular to an anchoring foundation and ocean engineering equipment. Background With the rapid development of the global offshore wind power industry, high-quality wind energy resources in offshore areas enter a saturated development stage, and deep and open sea areas have good development prospects due to the advantages of high wind energy density, small environmental influence, wide sea areas and the like. Conventional anchor foundations are commonly referred to as gravity anchors, pile anchors, drag anchors, and suction anchors. However, as the deployment depth increases, the construction and installation costs of the anchor foundation increase nonlinearly, and the installation difficulty becomes large, severely limiting the development of far-reaching wind energy resources. Disclosure of utility model In view of the above, the utility model provides an anchoring foundation and ocean engineering equipment to solve the problems of high installation difficulty and high construction and construction cost caused by the increase of water depth of the traditional anchoring foundation.
