[0002] The anchor chain for a buoy refers to a special chain that connects the anchor and the buoy and transmits the anchor holding force. Currently, the anchor chain is usually composed of a whole steel chain, which has a large self-weight and is difficult to drag. Moreover, the anchor chain composed of steel chains is easily corroded, affecting its use safety and service life. At the same time, the length of the steel chain is not easy to control, and it is not easy to operate when intercepting the required length of the steel chain during use, making it inconvenient to use.

The second eye loop is arranged in the middle of the flexible chain and is fixedly connected to the first eye loop and the third eye loop by means of a knot;

[0005] Among them, the flexible chain is made of a first fiber rope, specifically including: folding the fiber rope in half, knitting a first knot at an appropriate position of the two folded fiber rope segments to form the first eye loop, then knitting a second knot at an appropriate position after the first knot to form the second eye loop, and finally docking the ends of the two fiber rope segments to knit a third knot to form the third eye loop, where the step of forming the second eye loop is performed at least once; the flexible shackle is made of a second fiber rope.

Those skilled in the art should understand that this application can be implemented without some of these specific details. In the embodiments, some methods, means, instruments, devices, etc. well-known to those skilled in the art are not described in detail in order to highlight the gist of this application.

[0037] On the premise of no conflict, the technical features disclosed in the embodiments of this application can be combined arbitrarily, and the technical solutions obtained belong to the content disclosed in the embodiments of this application.

[0038] In some embodiments, the high-strength flexible anchor chain for a buoy includes flexible chains and flexible shackles arranged at intervals and repeated in sequence, where: the flexible chain includes a first eye loop, a third eye loop, and at least one second eye loop. The first eye loop is arranged at one end of the flexible chain and is detachably connected to the flexible shackle. The third eye loop is arranged at the other end of the flexible chain and is detachably connected to the flexible shackle. At least one second eye loop is arranged in the middle of the flexible chain and is fixedly connected to the first eye loop and the third eye loop by means of knots respectively; where the flexible chain is made of a first fiber rope, specifically including: folding the fiber rope in half, knitting a first knot at an appropriate position of the two folded fiber rope segments to form the first eye loop, then knitting a second knot at an appropriate position after the first knot to form the second eye loop, and finally butt-joining the ends of the two fiber rope segments to knit a third knot to form the third eye loop, where the step of forming the second eye loop is performed at least once; the flexible shackle is made of a second fiber rope.

[0039] Generally, the flexible chains and the flexible shackles are arranged at intervals and connected to each other in a detachable manner. Repeating the arrangement of the flexible chains and the flexible shackles can adjust the length of the flexible anchor chain; generally, flexible shackles can be arranged at both ends of the flexible anchor chain to connect the flexible anchor chain to the anchoring position. Generally, the flexible chain is made of a first fiber rope. During the manufacturing process, the first fiber rope is connected and fixed in a suitable manner to make it have a relatively stable structure. For example, a certain length of the first fiber rope can be folded, and the folded fiber rope segments are knitted with knots at intervals. After knitting the knots multiple times, a structure with eye loops and knots distributed at intervals is obtained. The knots can not only fix the relative positions between the fiber rope segments but also enhance the strength of the fiber chain. Generally, the first eye loop formed after folding the fiber rope is called the first eye loop and is located at the end of the flexible chain. The last eye loop formed after folding the fiber rope is called the third eye loop and is located at the other end of the flexible chain. The eye loops located between the first eye loop and the third eye loop are all called the second eye loops. For example, fold the fiber rope in half, knit a first knot at an appropriate position of the two folded fiber rope segments to form the first eye loop, then knit a second knot at an appropriate position after the first knot to form the second eye loop, and finally butt-join the ends of the two fiber rope segments to knit a third knot to form the third eye loop; where the operation step of knitting the second knot can be performed multiple times, and each execution adds one second eye loop. Generally, the appropriate position for knitting the first knot is selected according to the size of the first eye loop. Similarly, the position for knitting the second knot can also be selected according to the size of the second eye loop; generally, the sizes of the first eye loop, the second eye loop, and the third eye loop can be set as needed, and can be set to be the same or different; when multiple second eye loops are set, the sizes of the second eye loops can also be the same or different.

[0040] Generally, the flexible shackle is made of a second fiber rope. The flexible shackle has an openable structure and can be placed in the end eye loop of the flexible chain in the open state, and then the flexible shackle is fastened to achieve the connection between the flexible shackle and the flexible chain. Generally, the flexible shackle is a fiber rope made of a second fiber rope that can form an annular structure. Both ends of the fiber rope have an openable and lockable structure. For example, one end is a rope eye with adjustable size, and the other end is a knot adapted to it. The knot can pass through the rope eye, and the knot can be locked by adjusting the size of the rope eye. Generally, the knot has a certain size and a certain elasticity, and can change its shape under the action of an external force, and then change its size to facilitate passing through the rope eye. After passing through the rope eye, the shape is restored, and the knot can be locked with the rope eye. As an optional implementation manner, the flexible shackle includes an eye loop and a rope belt made of a second fiber rope. The end of the rope belt is woven to form a diamond knot, and the size of the diamond knot is adapted to the eye loop. The diamond knot can be embedded in the eye loop or taken out from it. As a flexible shackle, the buoy is connected to the flexible chain of the high-strength flexible anchor chain.

[0041] Generally, the first fiber rope and the second fiber rope can be set to be the same or different.

[0042] As an optional embodiment, the first fiber rope of the high-strength flexible anchor chain for buoy is a three-layer braided structure composed of a core, an intermediate layer and a rope skin. Among them, the core is a high-strength fiber, the intermediate layer is a sand-proof layer, and the rope skin is a wear-resistant fiber. For example, the core fiber can be ultra-high molecular weight polyethylene fiber, the intermediate layer can be non-woven fabric, and the rope skin can be ultra-high molecular weight polyethylene fiber.

[0043] As an optional embodiment, the second fiber rope of the high-strength flexible anchor chain for buoy is an ultra-high molecular weight polyethylene fiber rope.

[0044] As an optional embodiment, the surface of the first fiber rope of the high-strength flexible anchor chain for buoy is coated with a polyurethane resin layer. For example, usually, the first fiber rope can be surface-treated with a polyurethane resin solution to cover a layer of polyurethane resin on its surface, enhancing the waterproofness, anti-corrosion property of the first fiber rope, and improving its anti-aging ability to adapt to extreme environments such as high heat, extreme cold or high corrosion, and extending its service life.

[0045] As an optional embodiment, the third knot of the high-strength flexible anchor chain for buoy is obtained by the Brummel splice technique. Generally, the two ends of the first fiber rope are woven by the Brummel splice technique to form the third knot, and this knot can form a lock to prevent it from slipping and opening, forming a firm and solid third eye loop.

[0046] The following further illustrates the technical details in conjunction with embodiments.
