Description

Technical Field

[0001] This utility model belongs to the field of marine equipment, specifically relating to a multi-layer adaptive anchor chain device for complex terrain. Background Technology

[0002] Gravity anchor clusters are anchoring devices that provide pull-out resistance through their own weight and specific structural design. Gravity anchors are typically made of steel and concrete, and can weigh from hundreds to thousands of tons, possessing strong capabilities to withstand both horizontal and vertical forces. Common anchor blocks are single large blocks, sometimes arranged in a honeycomb pattern, with ballast added after placement on the seabed. Additional anchor claws are used to further increase the holding power of the anchor block. However, when gravity anchors are in complex marine environments, they are affected by wave loads. In complex seabed topography, traditional single large anchor blocks cannot effectively cope with complex forces and adapt to changing terrain, thus affecting their safety.

[0003] For example, Chinese patent CN118877123A (publication date: November 1, 2024) discloses a hollow hexagonal gravity group anchor, belonging to the field of anchoring technology. It includes a main anchor chain and a hollow hexagonal gravity group anchor, which adapts to the seabed topography during anchoring through the dispersed hollow hexagonal gravity anchor blocks. This solution can overcome the problems of existing gravity anchors, such as a single source of anchoring force, low safety redundancy of anchor blocks, and poor terrain adaptability. However, this structure is prone to situations where only some gravity anchors bear the force when under stress, and there is no interconnection between the gravity anchors, failing to achieve true terrain adaptability and exhibiting structural redundancy without saving materials.

[0004] For example, Chinese patent CN118722956A (publication date: October 1, 2024) discloses a terrain-adaptive gravity anchor group, belonging to the field of anchoring technology. It includes anchor blocks, main anchor chains, warp anchor chains, weft anchor chains, and U-shaped lifting lugs, connecting individual gravity anchor blocks into a network-like gravity anchor group. This invention overcomes the problems of low anchoring efficiency, poor terrain adaptability, and low stability of existing gravity anchors. Although the structure establishes connections between anchor blocks through warp anchor chains, the reset function after the overall structure is subjected to force, the anchoring function of individual anchor blocks, and the structural adaptability need improvement.

[0005] Therefore, it is necessary to design a device that can establish connections between anchor blocks while improving the overall structural repositioning and terrain adaptation functions. Utility Model Content

[0006] This utility model connects anchor blocks in pairs, sets up a multi-level adaptive structure, and realizes the reset function of the structure through movable connection, providing a multi-level adaptive anchor chain device for complex terrain. The device is characterized by including an upper connecting layer and a lower adaptive layer.

[0007] The upper connecting layer is a lifting ring connected to the upper structure; the lower adaptive layer is movably disposed inside the lifting ring of the upper connecting layer;

[0008] The lower adaptive layer is a group of anchor chains with more than one layer of equal length. The overall shape is a tree branch, with the number of branched anchor chains increasing from top to bottom. Each layer of branched anchor chains is an even multiple.

[0009] Furthermore, the lower adaptive layer consists of multiple layers of anchor chain groups, with each layer of anchor chain groups being dynamically connected.

[0010] Furthermore, in the lower adaptive layer anchor chain group, the forked anchor chains in the anchor chain group are paired up to form anchor chain pairs. The middle part of the anchor chain pair is an anchor chain, and the two ends are lifting rings. The middle anchor chains of multiple anchor chain pairs are movably arranged inside the upper lifting rings.

[0011] Furthermore, each lifting ring below the bottommost anchor chain group of the lower adaptive layer is connected to a gravity anchor.

[0012] Furthermore, in each layer of the lower adaptive layer anchor chain group, the number of anchor chain pairs set in the lifting rings at both ends of the anchor chain pair is equal.

[0013] Furthermore, each of the lower adaptive layers includes multiple anchor chain pairs of 1 or more.

[0014] Furthermore, the gravity anchor of the lower adaptive layer is a small stone with a large self-weight that is easy to obtain.

[0015] Furthermore, the anchor chain device has a movable symmetrical structure.

[0016] Compared with existing technologies, the advantages and effects of the technical solution in this application are as follows:

[0017] 1. This invention provides a multi-layer adaptive anchor chain device for complex terrain, which has the function of multi-layer force distribution. The middle connecting layer can bear part of the external force generated by the superstructure or seawater disturbance. The bottom adaptive layer is connected to the gravity anchors at both ends of each anchor chain through the anchor chain. When one gravity anchor is moved by force, the other gravity anchor is connected to it, so that the force can be distributed together.

[0018] 2. This invention provides a multi-layer adaptive anchor chain device for complex terrain. It is a movable symmetrical structure that can be reset through the buoyancy of the upper structure and the connection between the various structures, thus adapting well to complex seabed terrain.
