Description

Technical Field

[0001] This invention belongs to the field of marine equipment technology, specifically relating to a split-type underwater floating platform structure with adjustable buoyancy. Background Technology

[0002] In recent years, my country's marine industry has maintained a rapid pace of development, with various types of underwater floating platforms emerging continuously. Due to the harsh marine environment, underwater floating platforms must possess strong environmental adaptability. The turbulence caused by waves places high demands on the stability of underwater floating platforms. Simultaneously, multifunctionality, flexibility, and payload capacity have become design principles and long-term goals for various types of underwater floating platforms. Traditional floating platforms mostly use steel or concrete, which are prone to corrosion, heavy, have high maintenance costs, and poor stability in complex sea conditions. Furthermore, they are usually designed for fixed purposes, with poor expandability and adaptability. They are no longer adequate to meet the demands of the new situation and background for underwater floating platforms to possess stronger stability, higher adaptability, and richer functional modules. Therefore, there is an urgent need for a floating platform structure that can maintain stability in the ocean, expand with external functional modules, and adjust load capacity. Summary of the Invention

This structure has good underwater stability, its buoyancy can be flexibly adjusted according to the load weight, the main structure adopts a split-type design to facilitate installation and maintenance, and it has reserved a wealth of functional expansion interfaces.

[0004] The technical solution of this invention is to provide a split-type underwater floating platform structure with adjustable buoyancy, including...

[0005] Several lifting rings are symmetrically installed on the upper surface for lifting purposes;

[0006] The first and second halves of the shell are symmetrical in structure and are combined by connectors to form a hollow frustum structure. The outer surface of the shell is provided with guide fins that can stabilize the attitude, the upper surface is provided with multiple mounting slots, and the lower surface is provided with stepped mounting slots.

[0007] A bracket is fixed to the lower surfaces of the first and second split shells for temporary support.

[0008] Multi-layered buoyancy pads are nested within stepped mounting slots, and buoyancy can be adjusted by increasing or decreasing the number of layers.

[0009] This invention allows for adjustment of the load on the intermediate clamp by changing the inner and outer diameters of the first and second semi-shells. It also allows for expansion of external functionality by altering the number and size of mounting slots on the upper surface. A bracket, fixed to the lower surface of the first and second semi-shells with screws, provides temporary support. Multiple layers of buoyancy pads are nested and fixed according to the bottom slot dimensions of the first and second semi-shells. The buoyancy of the floating platform can be controllably adjusted by increasing or decreasing the number of buoyancy pad layers.

[0010] Preferably, the first split shell is a semi-frustum structure made of composite material such as polyamide resin, including: a first mounting slot and a first lifting ring mounting hole on the upper surface; a first semi-cylindrical cavity in the middle for accommodating loads; first guide fins on the sidewalls; a semi-annular stepped first stepped mounting slot at the bottom for nesting and mounting buoyancy pads; and a first mounting support plate for connecting to the second split shell. The multiple mounting slots on the upper surface, designed according to functional requirements, enable it to have various forms of extended functions.

[0011] Preferably, the second semi-shell is a frustum structure made of a composite material such as polyamide resin, comprising: a second mounting slot and a second lifting ring mounting hole on the upper surface; a second semi-cylindrical cavity in the middle for accommodating the load; second guide fins on the sidewalls; a semi-annular second stepped mounting slot at the bottom for nesting and mounting a buoyancy pad; and a second mounting support plate for connecting to the first semi-shell. The multiple mounting slots on the upper surface, designed according to functional requirements, enable it to perform various forms of extended functions.

[0012] Preferably, there is an even number of lifting rings, each lifting ring comprising a ring and a threaded screw, and they are symmetrically installed in the first lifting ring mounting hole and the second lifting ring mounting hole via a threaded connection.

[0013] Preferably, the bracket includes: a semi-circular plate with mounting holes and weight-reducing holes; a T-shaped support leg welded to the lower surface of the semi-circular plate; and a plate welded to the bottom of the support leg to increase the support area.

[0014] Preferably, the buoyancy pad is made of a low-density buoyancy material such as resin, and is in the form of a stepped semi-circular shape. Its shape matches the first stepped mounting groove and the second stepped mounting groove, and it is provided with a round hole to assist in nesting installation. The stepped semi-circular shape can be paired with the first stepped mounting groove and the second stepped mounting groove on the first half-shell and the second half-shell, respectively.

[0015] Preferably, the guide fins are evenly distributed to enhance underwater stability.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. This invention proposes a buoyancy-adjustable split-type underwater floating platform structure with multiple fins on its outer surface, which can improve the overall stability of the floating platform in the marine environment. By adjusting the mounting slots on the upper surfaces of the first and second split shells, the external functions of the floating platform can be easily expanded and the ease of operation and maintenance can be improved.

[0018] 2. The present invention can adjust the buoyancy of the floating platform by increasing or decreasing the number and thickness of the multi-layer buoyancy pads, so that the floating platform can adapt to different weight loads within a certain range. At the same time, the diameter of the middle semi-cylindrical cavity, which serves as the load receiving groove, can be designed to accommodate loads of different diameters, which has extremely high scalability and convenience.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0027] like Figure 1-6As shown, a buoyancy-adjustable split-type underwater floating platform structure includes several lifting rings 101 symmetrically installed on the upper surface of the underwater floating platform for hoisting; a first split shell 102 and a second split shell 103, which are symmetrical in structure and are combined by connectors to form a hollow frustum structure. The outer surface of the frustum is provided with guide fins, the upper surface is provided with multiple mounting slots, and the lower surface is provided with stepped mounting slots; a bracket 104 is fixed to the lower surface of the first split shell 102 and the second split shell 103 for temporary support; and multi-layer buoyancy pads 105 are nested in the stepped mounting slots, and the buoyancy can be adjusted by increasing or decreasing the number of layers.

[0028] The first half-shell 102 is a frustum-shaped structure made of polyamide resin, including a first mounting groove 3 and a first lifting ring mounting hole 4 on the upper surface; a first semi-cylindrical cavity 5 in the middle for accommodating the load; first guide fins 6 on the side walls; a semi-annular first stepped mounting groove 7 at the bottom for nesting and mounting the buoyancy pad 105; and a first mounting support plate 9 for connecting with the second half-shell 103. Similarly, the second half-shell 103 is a frustum-shaped structure made of polyamide resin, including a second mounting groove 10 and a second lifting ring mounting hole 11 on the upper surface; a second semi-cylindrical cavity 12 in the middle for accommodating the load; second guide fins 13 on the side walls; a semi-annular second stepped mounting groove 14 at the bottom for nesting and mounting the buoyancy pad 105; and a second mounting support plate 16 for connecting with the first half-shell 102.

[0029] In one embodiment, the buoyancy pad 105 is made of resin foam and is in the shape of a stepped semi-circular ring. Its shape matches the first stepped mounting groove 7 and the second stepped mounting groove 14, and it is provided with two round holes 22 to assist in nesting installation.

[0030] In this embodiment, the bracket 104 includes a semi-annular plate 19 with mounting holes 17 and weight reduction holes 18; two T-shaped legs 20 welded to the lower surface of the semi-annular plate 19; and a plate 21 welded to the bottom of the legs 20 to increase the support area.

[0031] The first and second halves of the housing 102 and 103 are fastened together with bolts and nuts to form a hollow frustum structure. The cylindrical hollow part is used to clamp the main load, and the multiple mounting slots on the upper surface allow for easy expansion of external functions and simple maintenance. Two brackets 104 are fastened to the lower surfaces of the first and second halves of the housing 102 and 103 respectively with screws, providing support. The buoyancy pads 105 are nested within the first and second stepped mounting slots 7 and 14 on the lower surfaces of the first and second halves of the housing 102 and 103 according to their design dimensions, using their two circular holes 22. During use, the number of layers and the thickness of each layer of the buoyancy pads 105 can be adjusted according to the actual load weight, thereby achieving load adjustment within a certain range.

[0032] In one embodiment, there is an even number of lifting rings 101. Each lifting ring 101 includes a ring 1 and a threaded screw 2, and is symmetrically installed in the first lifting ring mounting hole 4 and the second lifting ring mounting hole 11 by means of threaded connection.

[0033] The first half-shell 102 is a composite material molded from a single piece of polyamide resin. It is formed into an irregular half-cylindrical structure by processing the first mounting groove 3, the first lifting ring mounting hole 4, the first semi-cylindrical cavity 5, the first guide fin 6, and the first stepped mounting groove. It is installed with the bracket 104 through the mounting hole 8 on the lower surface. The second half-shell 103 can be combined and installed with the first half-shell 102 through the first mounting support plate 9.

[0034] The second half-shell 103 is also made of a single piece of composite material. By machining the second mounting groove 10, the second lifting ring mounting hole 11, the second semi-cylindrical cavity 12, the second guide fin 13, and the second stepped mounting groove 14, it becomes an irregular half-cylindrical structure. The bracket 104 is installed through the second mounting hole 15 on the lower surface. The first half-shell 102 can be combined with the second half-shell 103 through the second mounting support plate 16.

[0035] The split-type underwater floating platform structure of this invention features multiple fins on its outer surface, which improves the overall stability of the platform in a marine environment. By adjusting the mounting slots on the upper surfaces of the first and second split shells, the platform's external functionality can be easily expanded, and operation and maintenance can be simplified. Furthermore, the buoyancy of the platform can be adjusted by increasing or decreasing the number and thickness of the multi-layered buoyancy pads, enabling the platform to adapt to different weight loads within a certain range. Additionally, the diameter of the central semi-cylindrical cavity, which serves as the load-bearing groove, can accommodate loads of different diameters, providing extremely high scalability and convenience.
