Description

Technical Field

[0001] This invention belongs to the field of marine equipment technology, specifically relating to a variable buoyancy split-half float structure. Background Technology

[0002] In marine economic activities, whether in the aquaculture industry or national defense research, buoys occupy an important position. In recent years, my country's marine economy has developed extremely rapidly. To adapt to this economic development, various types of buoys have emerged. Due to the vastness and harshness of the ocean environment, there are many application scenarios for various equipment and loads. This has placed new demands on marine buoys, meaning that buoys are in high demand and can adapt to various loads, while also being firmly installed to resist the erosion of waves. Traditional buoys are mostly spherical structures with single buoyancy, and when installed in half, the clamping force on the cable is usually insufficient, making the buoy easy to move along the cable. At the same time, various specifications of buoys are required for various buoyancy scenarios and large-scale use, resulting in high deployment costs. Furthermore, traditional buoys are usually designed for fixed purposes, with poor expandability and adaptability.

[0003] The new situation and background require buoys to have stronger installation and secureness, higher buoyancy adaptability, and the ability to adapt to various buoyancy conditions with a single buoy, while reducing mass production costs and simplifying and effectively maintaining them. To adapt to this new situation and new development, there is an urgent need for a buoy structure with variable buoyancy and reliable installation and secureness in the ocean. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a variable buoyancy split-half float structure, which can conveniently change the buoyancy by adjusting the internal medium to adapt to different load requirements; at the same time, through the unique rubber pad design, it can reliably clamp the cable, prevent the float from slipping, and protect the cable from damage.

[0005] The technical solution of the present invention is to provide a variable buoyancy split-half float structure, comprising:

[0006] Two semi-buoys are symmetrically connected and detachably joined to form a single buoy with a central channel.

[0007] The two split floats each have a sealed cavity inside to hold a medium that can adjust the overall buoyancy of the floats;

[0008] Each of the split floats has a square groove extending axially along the central channel on its docking surface;

[0009] Two rubber pads are respectively embedded in the square grooves of the two split floats, and each rubber pad has a semi-circular groove on the side facing the central channel. When the two split floats are connected, the semi-circular grooves of the two rubber pads together form a clamping hole for clamping the cable passing through the central channel.

[0010] Preferably, each of the split floats has a platform on its outer surface. When two split floats are connected, the platform forms a support plane to prevent the floats from rolling. By providing the mounting platform, free rolling of the floats during placement can be prevented.

[0011] Preferably, each of the split floats has a sealing hole on its platform that communicates with the cavity, and also includes a sealing plug assembly for sealing the sealing hole.

[0012] Preferably, the sealing plug assembly includes a sealing plug with external threads and a sealing ring fitted onto the sealing plug, and the sealing hole has an internal thread that mates with the external threads. It can be easily installed on the surface platform of the split float to achieve a sealing function.

[0013] Preferably, the split float is made of a composite material and is shaped like a split rugby ball with sharpened flat surfaces at both ends. The composite material is a polymer such as glass microspheres or polyamide.

[0014] Preferably, the two split floats are connected by fasteners passing through their mounting holes.

[0015] Preferably, the central channel formed on the split float is a variable cross-section channel, wherein the cross-sectional area of ​​the variable cross-section channel in the internal region of the float is smaller than its cross-sectional area at the port of the float.

[0016] Preferably, the inner surface of the semi-circular groove is provided with textures or protrusions to increase friction.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] The split-buoy has a hollow structure, and its buoyancy can be adjusted by injecting a medium into the hollow part. This allows the buoy to adapt to various buoyancy conditions, expands its usability, and reduces the cost of use. In addition, the rubber pad in the middle part of the buoy increases the friction against the passing cable, improving the overall installation and tightness of the buoy. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0025] A variable buoyancy split-half float structure, such as Figures 1-4 As shown, it mainly includes a sealing plug assembly 101, two split floats 102, and a rubber pad 103.

[0026] Among them, the two split floats 102 are symmetrical structures with mounting holes 7. They are fastened together by hexagonal bolts and nuts through them to form an oval-shaped float structure. The center of the float structure has a central channel for passing through cables. The central channel is a variable cross-section channel 8. The cross-sectional area of ​​the variable cross-section channel 8 inside the float is smaller than its cross-sectional area at the float port, making the central channel narrower inside and wider outside. This ensures that the cables are clamped while not causing significant friction and compression damage to the float port.

[0027] Specifically, each of the two semi-buoys 102 has a sealed cavity 11 inside to hold a medium that adjusts the overall buoyancy of the buoy. The buoyancy of each semi-buoy can be adjusted by injecting the medium into its hollow portion. Each semi-buoy 102 has a square groove 9 extending axially along the central channel on its mating surface. Rubber pads 103 are nested within the square grooves of the two semi-buoys 102, serving to clamp the cable and increase friction. During use, the buoyancy of the semi-buoys 102 can be adjusted according to the actual load weight, thus achieving variable buoyancy within a certain range. The medium can be water or solid particles such as sand.

[0028] In this embodiment, each rubber pad 103 has a semi-circular groove 12 on one side facing the central channel. When the two semi-floating balls 102 are connected, the semi-circular grooves 12 of the two rubber pads 103 together form a clamping hole for clamping the cable passing through the central channel.

[0029] Furthermore, the inner surface of the semi-circular groove 12 is provided with textures or protrusions to increase friction.

[0030] In one implementation, each of the split floats 102 has a platform 5 on its outer surface. When two split floats 102 are connected, the platform 5 forms a support plane to prevent the floats from rolling. By providing the platform 5, free rolling of the floats during placement can be prevented.

[0031] Furthermore, each of the split floats 102 has a sealing hole 6 on its platform 5 that communicates with the cavity 11, and is also equipped with two sealing plug assemblies 101 for sealing the sealing hole 6. The two sealing plug assemblies 101 are respectively installed in the sealing holes 6 of the two split floats 102 for sealing.

[0032] In one embodiment, the sealing plug assembly 101 includes a sealing plug 1 and a sealing ring 2 fitted on the sealing plug 1. The sealing plug has a structure with a sealing groove 3 and an external thread 4, and the sealing hole 6 has an internal thread that mates with the external thread 4.

[0033] In one embodiment, the split float 102 is made of glass microspheres and is shaped like a split rugby ball with sharpened flat surfaces 10 at both ends.

[0034] This invention allows the buoyancy of the float to be adjusted by injecting a medium into the hollow part, enabling the float to adapt to various buoyancy conditions and expanding its usability while reducing operating costs. Furthermore, the rubber pad in the middle of the float increases friction against the passing cables, improving the overall stability of the float during installation. Additionally, the platform prevents the float from rolling freely during placement.

[0035] The above description only illustrates preferred embodiments of the present invention and should not be construed as limiting the scope of the claims. Any equivalent procedural modifications made using this specification are included within the patent protection scope of this invention.
