Embodiment Construction

[0062] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0063] 1. Power-installed anchors for multi-anchor mooring

[0064] Figure 1a and Figure 1b It is a multi-anchor mooring power installation anchor 1, mainly composed of an anchor body 101, an anchor handle 102, a tangential wing 104 and a normal wing 106.

[0065] The anchor body 101 is composed of upper and lower parts, the upper part 101a of the anchor body is a section of cylinder, and the lower part 101b of the anchor body is in the shape of a gradually shrinking semi-ellipsoid. The lower portion 101b of the anchor body is provided with a semi-ellipsoidal groove, which helps to reduce the resistance of the anchor when it falls in water and penetrates into the seabed. The cylindrical inner space of the upper part 101a of the anchor body and the groove of the lower part 101b of the anchor body form an...

Abstract

The invention belongs to the technical field of ocean engineering, and relates to a multi-anchor-point mooring power installation anchor and an installation method thereof. The multi-anchor-point mooring power installation anchor is provided with a plurality of anchor eyes, can be connected with a plurality of floating structures at the same time, and is very suitable for the fields of offshore wind turbines, marine ranching, offshore solar power generation and the like which are arranged in groups or in pieces. Due to the design of the multi-anchor-point mooring power anchor, the horizontal load acting on an anchor body can be reduced or even eliminated, so that the load acting on the anchor body is mainly a vertical pull-up load, the load bearing mode of the anchor body is optimized, andthe bearing efficiency of the anchor body is improved. Due to the design of a normal wing plates, the resistance borne by a combined anchor can be reduced. In the recovery process of a booster, the normal wing plates gradually extend out of the anchor body, the normal loading area of the multi-anchor-point mooring power installation anchor is increased, and then the bearing efficiency of the anchor is remarkably improved. The anchor is high in installation efficiency, low in cost, high in bearing efficiency and good in loading mode, and the installation cost of an anchoring foundation can beremarkably reduced.

Description

technical field [0001] The invention belongs to the technical field of marine engineering, and relates to a multi-anchor mooring dynamic installation anchor and an installation method thereof. Background technique [0002] The development of marine resources and space requires a series of floating structures, which are connected to anchor foundations through anchor chains. The anchor foundations currently used in marine engineering mainly include pile anchors, suction anchors, drag anchors, plate anchors and dynamic installation anchors. Compared with the previous types of anchor foundations, the dynamic installation anchor relies on the gravitational potential energy of the anchor to drop at high speed in seawater and penetrate into the seabed, which has the advantages of high installation efficiency and low cost. Currently, the dynamic installation anchors used in marine engineering mainly include torpedo-shaped dynamic anchors (US patent, patent No. US7878137B2) and plat...
