Description

Technical Field

[0001] This utility model relates to the field of buoy anchor chain technology, specifically a buoy anchor chain anti-entanglement mechanism. Background Technology

[0002] Buoys, as important maritime markers, are widely used in marine surveying, navigation channel indication, aquaculture, marine environmental monitoring, and water recreation. Buoys are typically connected to an anchor block submerged in the water via an anchor chain to maintain them within a predetermined position.

[0003] However, in the natural environment, buoys are subject to the combined effects of external forces such as wind, waves, and currents, resulting in complex multi-degree-of-freedom motion. This motion causes the anchor chain beneath it to repeatedly twist and swing. Anchor chain entanglement on the buoy's bottom or knotting itself alters the buoy's normal draft and attitude, affecting the accuracy and visibility of its marking function. Secondly, entanglement increases localized stress on the anchor chain, accelerating fatigue damage and posing a risk of breakage. For monitoring buoys equipped with solar panels or communication antennas, entanglement may fix the buoy's orientation, preventing it from turning with light or wind, causing equipment malfunction.

[0004] Therefore, a buoy anchor chain anti-entanglement mechanism is needed to improve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a buoy anchor chain anti-entanglement mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A buoy anchor chain anti-entanglement mechanism, comprising:

[0008] The mounting body includes a main plate and a cover plate that is bolted to the middle of the upper surface of the main plate. The main plate has an inner groove inside.

[0009] A turntable, wherein the turntable is rotatably connected to the cover plate;

[0010] A buffer assembly is disposed on both sides of the lower surface of the turntable, and the buffer assembly is connected to the end of the anchor chain.

[0011] The counterweight is fixedly connected to the lower surface of the main disc, and its lower end is inserted into the anchor chain body.

[0012] As a preferred embodiment of this utility model, the main disc body has several bolt holes at equal intervals on its side, and the main disc body is fixedly connected to the bottom of the buoy by bolts.

[0013] As a preferred embodiment of this utility model, the buffer assembly includes a set of extension columns, each of which has a side groove on its inner side. A guide column is fixedly connected inside the side groove, and a connecting rod is connected between the two guide columns. A buffer element is provided inside the side groove.

[0014] As a preferred embodiment of this utility model, the buffer component includes an elastic sleeve and a buffer pad, wherein the buffer pad is disposed at the lower end of the side groove and covers the outside of the guide post.

[0015] As a preferred embodiment of this utility model, the elastic sleeve is disposed on the outside of the guide post, and its upper and lower ends are respectively connected to the turntable and the connecting rod.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model solves the problem in the background technology that anchor chains become entangled with buoys or knotted due to complex external forces. The rotatable connection between the turntable and the installation body forms the first barrier against entanglement, avoiding the continuous accumulation of torque that leads to anchor chain entanglement.

[0020] 2.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] Please see Figure 1-3 This utility model provides a technical solution:

[0030] For an example, please refer to... Figure 1 , 2 3. A buoy anchor chain anti-entanglement mechanism includes an installation body, a turntable 7, a set of buffer components, and a counterweight. The installation body serves as the load-bearing foundation of the entire mechanism and is composed of a main disc 1 and a cover plate 2. The main disc 1 is securely installed on the bottom of the buoy using bolts through several bolt holes equally spaced on its side, ensuring that the mechanism and the buoy become a whole. The cover plate 2 is installed on the middle of the upper surface of the main disc 1 by bolts. The two together enclose an internal space, namely the inner groove 6 opened inside the main disc 1. This split structure facilitates internal installation and maintenance.

[0031] A connecting post 8 is fixedly connected to the center of the lower surface of the main disc 1. The turntable 7 is fitted onto the outside of the connecting post 8 via conventional rotating components such as bearings, allowing the turntable 7 to rotate freely horizontally relative to the mounting body and the buoy body. When water flow or wind attempts to drive the buoy to rotate, the turntable 7 and the components below it can remain relatively stationary or rotate in the opposite direction, thereby effectively dissipating the torsional force transmitted to the anchor chain. This is the first barrier against entanglement.

[0032] On both sides of the lower surface of the turntable 7, there are buffer components. The components include a pair of extension posts 3 fixed on the turntable 7. Each extension post 3 has a side groove 13 on its inner side. A guide post 12 is fixedly connected inside the side groove 13. A connecting rod 9 for connecting the end of the anchor chain is connected between the two guide posts 12. The chain link or shackle at the end of the anchor chain can be hung on this connecting rod 9.

[0033] Specifically, the buffer includes an elastic sleeve 11 sleeved on the outside of the guide post 12 and a buffer pad 10 disposed at the lower end of the side groove 13 and covering the guide post 12. The upper and lower ends of the elastic sleeve 11 are connected to the turntable 7 and the connecting rod 9, respectively. When the buoy rises and falls violently in the wind and waves, generating a sudden upward force on the anchor chain, the force will compress the elastic sleeve 11 through the connecting rod 9. The elastic sleeve 11 undergoes elastic deformation, absorbing most of the impact energy. At the same time, the connecting rod 9 will move downward along the guide post 12 and eventually contact the buffer pad 10. The further deformation of the buffer pad 10 will buffer the hard impact at the extreme position, greatly mitigating the instantaneous impact force and preventing the anchor chain from being rapidly thrown towards the buoy body due to sudden straightening, thereby significantly reducing the probability of entanglement. This is the second barrier against entanglement.

[0034] Please refer to Figure 1 , 2 In addition to 3, to further improve stability, a counterweight is fixedly connected to the lower surface of the main plate 1. In this embodiment, the counterweight includes a counterweight rod 5. The two ends of the counterweight rod 5 are connected to the lower surface of the main plate 1 through connecting ropes 4. The counterweight rod 5 is suspended below the mechanism through connecting ropes 4 and is inserted into the anchor rod to increase the weight of the lower part of the anchor chain. The end of the anchor chain is vertical, which makes the buoy's posture in the water more stable and less prone to large tilting and shaking.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
