Description

Technical Field

[0001] This utility model belongs to the field of anchoring and anchoring chains, specifically relating to an anti-slip gravity anchor device suitable for navigation marks. Background Technology

[0002] Navigational aids are crucial markers for maritime navigation, and their stability directly impacts the safe passage of ships. A gravity anchor is a device that provides a stable anchoring point through its own weight or by embedding itself in the seabed. Gravity anchors typically sink to the seabed, forming a robust anchoring system through the combination of their own weight and the resistance of seabed sediment. Improving the anchoring capacity of gravity anchors plays a vital role in the stable operation of navigational aids.

[0003] For example, Chinese patent CN221914530U (publication date: April 18, 2024) discloses a gravity anchor for a floating photovoltaic system, including a gravity anchor body with multiple through holes. A steel pipe is slidably fitted into each through hole. A limiting member is provided at one end of the steel pipe, abutting against the top surface of the gravity anchor body. An anchoring member is provided at the end of the steel pipe away from the limiting member, for insertion into the seabed. This invention can convert the horizontal bearing capacity of the gravity anchor body from friction to friction and tensile force, maximizing the horizontal bearing capacity of the gravity anchor body and greatly reducing the risk of slippage. However, the manufacturing process of creating through holes in the gravity anchor is complex, and it is easily damaged during use.

[0004] Chinese Patent CN117721836A (Publication Date: March 19, 2024) discloses a gravity foundation structure with a root key, including a gravity anchor body. The bottom of the gravity anchor body has several holes, and a split-type jack is installed through the holes. The output end of the jack is connected to the push rod inside the jack push rod. The output end of the push rod is equipped with a root key through a connector. The bottom end of the root key is provided with a root tip. The jack can push the root key into the foundation through the push rod.

[0005] Gravity anchors are generally made of materials such as concrete and steel, or selected from large stones, which have great weight and stability, and it is not convenient to make holes in them. Therefore, it is necessary to design a device that can be used for most gravity anchors, which is simple to manufacture and easy to replace. Utility Model Content

[0012] Furthermore, the fastening structure includes a threaded screw and threaded holes at both ends of the fixing ring. The threads of the screw and the threaded holes are matched, and the fixing ring is fixed by the fastening action between the threaded holes and the screw.

[0013] Furthermore, the anchor plate of the anchor is arranged perpendicular to the steel pipe.

[0014] Furthermore, the anchor plate of the anchor is a disc extending around the fixing ring.

[0015] Furthermore, the inner diameter of the fixing ring is larger than the circumference of the position where the gravity anchor fixes the device.

[0017] Furthermore, the fixing ring is strip-shaped and made of flexible high-strength steel.

[0018] Furthermore, several anti-slip gravity anchor devices are installed around the gravity anchor according to actual usage requirements.

[0039] The anchor includes multiple sets of anchor rods, and each set of anchor rods includes a steel pipe and multiple anchor plates.

[0040] Furthermore, the fastening structure 3 includes a threaded screw 6 and threaded holes 7 at both ends of the fixing ring. The threads of the screw 6 and the threaded holes 7 are matched, and the fixing ring 1 is fixed by the fastening action of the threaded holes 7 and the screw 6.

[0041] Furthermore, the anchor plate of the anchor 2 is arranged perpendicular to the steel pipe.

[0042] Furthermore, the anchor plate of the anchor 2 is a disc that extends around the fixing ring.

[0043] Furthermore, the inner diameter of the fixing ring 1 is larger than the circumference of the device position fixed by the gravity anchor 5.

[0044] Furthermore, the fixed ring has multiple threaded holes 7 at both ends to accommodate different sizes of the gravity anchors 5.

[0045] Furthermore, the fixing ring 1 is strip-shaped and made of flexible high-strength steel.
