Description

Technical Field

[0002] With the deepening development and utilization of marine resources, the application of offshore floating structures in marine engineering is becoming increasingly widespread, such as offshore wind power platforms, floating production storage and offloading (FPSO) devices, and marine aquaculture platforms. These floating structures are typically composed of multiple modules or units, requiring reliable connection technologies to ensure the stability and functionality of the overall structure. In traditional offshore floating equipment, the connection of offshore floating bodies mainly adopts bolting or welding methods. Bolting requires divers to perform underwater installation and tightening operations, while welding requires on-site welding using large equipment after the floating body modules are joined. Both methods have the problems of complex installation and long construction periods. Utility Model Content

[0014] Secondly, this application provides a marine floating device, including: a connecting device as described in any of the foregoing embodiments.

[0015] The connecting device of this application has the following advantages:

[0016] In the connecting device of this application, a second connector is embedded in one of the floats to connect the second connector to the float, and a third connector is embedded in the other float to connect the third connector to the float. Since the second connector is connected to one end of the first connector along a predetermined direction, and the third connector is connected to the other end of the first connector along the predetermined direction, the second connector and the third connector can be connected through the first connector, thus connecting the two floats through the connecting device. During this process, in the predetermined direction, the projected area of ​​the second connector on the first connector gradually increases towards the direction away from the first connector. Therefore, when the second connector is embedded in the float... This design improves the stability of the interference fit between the second connector and the float, thereby enhancing the connection stability between them. Similarly, in the preset direction, the projected area of ​​the second connector on the first connector gradually increases towards the direction away from the first connector.

[0033] Reference Figure 1 as well as Figure 2 As shown, the connecting device involved in the embodiment of this application has a preset direction x, and the connecting device includes: a first connecting member 100, a second connecting member 200 and a third connecting member 300.

[0034] Specifically, the second connector 200 is connected to one end of the first connector 100 along a preset direction x. In the preset direction x, the projected area of ​​the second connector 200 on the first connector 100 gradually increases in the direction away from the first connector 100. The second connector 200 is used to be embedded in one of the floats. The third connector 300 is connected to the other end of the first connector 100 along the preset direction x away from the second connector 200. In the preset direction x, the projected area of ​​the third connector 300 on the first connector 100 gradually increases in the direction away from the first connector 100. The third connector 300 is used to be embedded in another float.

[0035] It should be noted that the preset direction x is Figure 1 The direction indicated by x in the middle.

[0036] In the connecting device of this application, the second connector 200 is embedded in one of the floats to connect the second connector 200 to the float, and the third connector 300 is embedded in the other float to connect the third connector 300 to the float. Since the second connector 200 is connected to one end of the first connector 100 along a preset direction x, and the third connector 300 is connected to the other end of the first connector 100 along the preset direction x, the second connector 200 and the third connector 300 can be connected through the first connector 100, thereby connecting the two floats through the connecting device. In this process, in the preset direction x, since the projected area of ​​the second connector 200 on the first connector 100 gradually increases in the direction away from the first connector 100, when the second connector 200... When the second connector 200 is embedded in the float, it can improve the stability of the interference fit between the second connector 200 and the float, thereby improving the connection stability between the second connector 200 and the float. Similarly, in the preset direction x, since the projected area of ​​the second connector 200 on the first connector 100 gradually increases in the direction away from the first connector 100, when the second connector 200 is embedded in the float, it can improve the stability of the interference fit between the second connector 200 and the float, thereby improving the connection stability between the second connector 200 and the float. In this way, any two floats can be connected without using bolts or welding, and the connection method is simple. It is only necessary to embed the second connector 200 and the third connector 300 into one float respectively. In this way, the connection method of the floating bodies at sea can be simplified and the construction cycle can be shortened.

[0037] Reference Figure 2 As shown, the second connector 200 has a first connecting portion 210 and a second connecting portion 220, which are spaced apart and are both connected to the first connector 100. In a preset direction x, the first connecting portion 210 and the second connecting portion 220 are both angled to the preset direction x, and the first connecting portion 210 and the second connecting portion 220 gradually move away from the first connector 100.

[0038] In this embodiment, in the preset direction x, since both the first connecting portion 210 and the second connecting portion 220 are set at an angle to the preset direction x, and the first connecting portion 210 and the second connecting portion 220 gradually move away from the first connecting member 100, the projected area of ​​the second connecting member 200 on the first connecting member 100 gradually increases in the direction away from the first connecting member 100, thereby improving the stability of the interference fit between the second connecting member 200 and the float. Furthermore, since the first connecting portion 210 and the second connecting portion 220 are spaced apart, the second connecting member 200 can be interference-fitted with the float at different positions, thereby further improving the stability of the interference fit between the second connecting member 200 and the float.

[0039] Reference Figure 3 As shown, the angle between the first connecting part 210 and the preset direction x is α1, and the angle between the second connecting part 220 and the preset direction x is α2, satisfying: 30°≤α1≤50° and / or 30°≤α2≤50°.

[0040] Specifically, in some embodiments, α1 and α2 satisfy: 30°≤α1≤50° and 30°≤α2≤50°; in other embodiments, α1 and α2 satisfy: 30°≤α1≤50°; in still other embodiments, α1 and α2 satisfy: 30°≤α2≤50°, so that at least one of α1 and α2 can satisfy the requirement of being greater than or equal to 30° and less than or equal to 50°, in order to satisfy the requirement of interference fit between the second connector 200 and the float.

[0041] Specifically, in this embodiment, α1 can be 30°, 32°, 34°, 36°, 38°, 40°, 42°, 44°, 46°, 48°, 50°, etc., and α2 can be 30°, 31°, 33°, 35°, 37°, 39°, 41°, 43°, 45°, 47°, 50°, etc., and α1 and α2 can be equal or unequal.

[0042] In this embodiment, if α1 < 30°, the angle between the first connecting part 210 and the preset direction x will be too small, thus reducing the structural strength of the interference fit between the first connecting part 210 and the float. If α1 > 50°, the angle between the first connecting part 210 and the preset direction x will be too large, thus increasing the difficulty of embedding the second connecting member 200 into the float, leading to increased installation difficulty of the second connecting member 200 and the float. When 30° ≤ α1 ≤ 50°, the structural strength of the interference fit between the first connecting part 210 and the float is satisfied, while the installation difficulty of the second connecting member 200 and the float is reduced. Similarly, if α2 < 30°, the angle between the second connecting part 220 and the preset direction x will be too small, thus reducing the structural strength of the interference fit between the second connecting part 220 and the float. If α2 > 50°, the angle between the second connecting part 220 and the preset direction x will be too large, thus increasing the difficulty of embedding the second connecting part 200 into the float, leading to an increase in the installation difficulty of the second connecting part 200 and the float. When 30° ≤ α2 ≤ 50°, the structural strength of the interference fit between the second connecting part 220 and the float can be satisfied, and the installation difficulty of the second connecting part 200 and the float can be reduced.

[0043] Reference Figure 2 As shown, the third connector 300 has a third connecting portion 310 and a fourth connecting portion 320, which are spaced apart and are both connected to the first connector 100. In a preset direction x, the third connecting portion 310 and the fourth connecting portion 320 are both angled to the preset direction x, and the third connecting portion 310 and the fourth connecting portion 320 gradually move away from the first connector 100.

[0044] In this embodiment, in the preset direction x, since the third connecting part 310 and the fourth connecting part 320 are both set at an angle to the preset direction x, and the third connecting part 310 and the fourth connecting part 320 gradually move away from the first connecting member 100, the projected area of ​​the third connecting member 300 on the first connecting member 100 gradually increases in the direction away from the first connecting member 100, thereby improving the stability of the interference fit between the third connecting member 300 and the float. Furthermore, since the third connecting part 310 and the fourth connecting part 320 are spaced apart, the third connecting member 300 can be interference-fitted with the float at different positions, thereby further improving the stability of the interference fit between the third connecting member 300 and the float.

[0045] Reference Figure 3As shown, the angle between the third connecting part 310 and the preset direction x is α3, and the angle between the fourth connecting part 320 and the preset direction x is α4, satisfying: 30°≤α3≤50° and / or 30°≤α4≤50°.

[0046] Specifically, in some embodiments, α3 and α4 satisfy: 30°≤α3≤50° and 30°≤α4≤50°; in other embodiments, α3 and α4 satisfy: 30°≤α3≤50°; in still other embodiments, α3 and α4 satisfy: 30°≤α4≤50°, so that at least one of α3 and α4 can satisfy the requirement of being greater than or equal to 30° and less than or equal to 50°, in order to satisfy the requirement of interference fit between the third connector 300 and the float.

[0047] Specifically, in this embodiment, α3 can be 30°, 32°, 34°, 36°, 38°, 40°, 42°, 44°, 46°, 48°, 50°, etc., and α4 can be 30°, 31°, 33°, 35°, 37°, 39°, 41°, 43°, 45°, 47°, 50°, etc., and α3 and α4 can be equal or unequal.

[0048] In this embodiment, if α3 < 30°, the angle between the third connecting part 310 and the preset direction x will be too small, thus reducing the structural strength of the interference fit between the third connecting part 310 and the float. If α3 > 50°, the angle between the third connecting part 310 and the preset direction x will be too large, thus increasing the difficulty of embedding the third connecting member 300 into the float, leading to increased installation difficulty of the third connecting member 300 and the float. When 30° ≤ α3 ≤ 50°, the structural strength of the interference fit between the third connecting part 310 and the float is satisfied, while the installation difficulty of the third connecting member 300 and the float is reduced. Similarly, if α4 < 30°, the angle between the fourth connecting part 320 and the preset direction x will be too small, thus reducing the structural strength of the interference fit between the fourth connecting part 320 and the float. If α4 > 50°, the angle between the fourth connecting part 320 and the preset direction x will be too large, thus increasing the difficulty of embedding the third connecting part 300 into the float, leading to an increase in the installation difficulty of the third connecting part 300 and the float. When 30° ≤ α4 ≤ 50°, the structural strength of the interference fit between the fourth connecting part 320 and the float can be satisfied, and the installation difficulty of the third connecting part 300 and the float can be reduced.

[0049] Reference Figure 3 As shown, the length of the second connector 200 along the preset direction x is L1, which satisfies: 300mm≤L1≤500mm;

[0050] Specifically, in this embodiment, L1 can be 320mm, 340mm, 360mm, 380mm, 400mm, 420mm, 440mm, 460mm, 480mm, 500mm, etc.

[0051] In this embodiment, if L1 < 300mm, the length of the second connector 200 along the preset direction x will be too short, resulting in a short fitting area and fitting length between the second connector 200 and the float, affecting the structural strength of the interference fit between the second connector 200 and the float. If L1 > 500mm, the length of the second connector 200 along the preset direction x will be too short, resulting in an excessively long embedding length of the second connector 200 when it is embedded in the float, increasing the difficulty of fully embedding the second connector 200 and thus increasing the installation difficulty between the second connector 200 and the float. When 300mm ≤ L1 ≤ 500mm, the structural strength of the interference fit between the second connector 200 and the float can be satisfied, while reducing the installation difficulty of the second connector 200 and the float.

[0052] Reference Figure 3 As shown, the length of the third connector 300 along the preset direction x is L2, which satisfies: 300mm≤L2≤500mm.

[0053] Specifically, in this embodiment, L2 can be 320mm, 340mm, 360mm, 380mm, 400mm, 420mm, 440mm, 460mm, 480mm, 500mm, etc.

[0054] In this embodiment, if L2 < 300mm, the length of the third connector 300 along the preset direction x will be too short, resulting in a short fitting area and fitting length between the third connector 300 and the float, affecting the structural strength of the interference fit between the third connector 300 and the float. If L2 > 500mm, the length of the third connector 300 along the preset direction x will be too short, resulting in an excessively long embedding length when the third connector 300 is embedded in the float, increasing the difficulty of fully embedding the third connector 300 and thus increasing the installation difficulty between the third connector 300 and the float. When 300mm ≤ L2 ≤ 500mm, the structural strength of the interference fit between the third connector 300 and the float can be satisfied, while reducing the installation difficulty of the third connector 300 and the float.

[0055] In some embodiments, the second connector 200 and the third connector 300 are both carbon fiber connectors. Specifically, the carbon fiber connectors are made of carbon fiber reinforced composite material. Carbon fiber reinforced composite material is an advanced composite material composed of carbon fiber and resin matrix. It has advantages such as high strength and high modulus, lightweight, excellent corrosion resistance, good fatigue resistance, design flexibility (carbon fiber composite material can be molded into complex geometric shapes to meet the design requirements of different floating body interfaces), high damping performance, and low coefficient of thermal expansion. It not only solves the problems of corrosion resistance and impact resistance, but also greatly improves installation efficiency and service life.

[0056] In other embodiments, the connecting device further includes an anti-corrosion layer covering the surfaces of the second connector 200 and the third connector 300. Specifically, in some embodiments, the second connector 200 and / or the third connector 300 are made of TC4 titanium alloy, and the anti-corrosion layer covering their surfaces is a ceramic coating with a thickness of 150 μm. TC4 titanium alloy is a high-strength, low-density metallic material with a density of only 4.5 g / cm³. 3 It is far lower than that of steel (7.8g / cm³). 3 The lightweight nature of the TC4 titanium alloy reduces the stress on the overall structure of the buoy. The TC4 titanium alloy itself has excellent corrosion resistance and performs well in harsh environments such as seawater. However, to further enhance corrosion resistance, a ceramic coating is applied to the surface. This ceramic coating has extremely high chemical stability and can effectively isolate seawater, salt spray, and other corrosive media. When the coating thickness is 150 μm, it can form a dense protective barrier, significantly slowing down the corrosion rate of the second connector 200 and the third connector 300. In other embodiments, the second connector 200 and / or... Alternatively, the third connector 300 may be made of 316L stainless steel, with an epoxy coating covering its surface for corrosion protection. 316L stainless steel contains high levels of nickel (Ni) and molybdenum (Mo), giving it excellent resistance to pitting and crevice corrosion in chloride environments (such as seawater). 316L stainless steel not only has good mechanical strength but also excellent toughness, enabling it to maintain structural integrity under complex dynamic load conditions (such as wind and wave impact). The epoxy coating has excellent adhesion to the metal substrate and remains stable even during long-term use, making it difficult to peel off.

[0057] Reference Figure 1 As shown, the connecting device also includes a cathode protection element 400, which is electrically connected to the first connecting element 100.

[0058] In this embodiment, since the cathodic protection element 400 is electrically connected to the first connector 100, the first connector 100 can be prevented from corroding by using a sacrificial anode. A sacrificial anode is a method of protecting metal structures from corrosion through the principle of electrochemical corrosion. The cathodic protection element 400 is a metal or alloy that is more active (lower potential) than the first connector 100. When connected to the first connector 100 and placed in the same electrolyte (such as seawater, soil, etc.), a galvanic cell is formed due to the difference in their potentials. The sacrificial anode, as the anode of the galvanic cell, has a lower potential (more negative) and easily loses electrons to undergo an oxidation reaction. The first connector 100, as the cathode of the galvanic cell, has a higher potential (more positive) and accepts electrons from the sacrificial anode, so that the first connector 100 is always in a cathode state, avoiding corrosion. In this way, the cathodic protection element 400 can be preferentially corroded, thereby protecting the first connector 100. Thus, the connection device of this solution not only realizes the rapid connection between floats, but also effectively extends the service life of the connector and adapts to complex marine environments.

[0059] Specifically, in some embodiments, the cathodic protection element 400 is a zinc alloy composite anode (such as Zn-5%Al-0.1%Si), which has high current efficiency and long service life, and its surface can be coated with a graphene-reinforced epoxy resin coating layer to further improve corrosion resistance. In other embodiments, the cathodic protection element 400 can also be an aluminum-based anode (Al-7%Zn-0.1%In). Aluminum-based anodes have higher current efficiency and capacitance, and can provide stronger protection capabilities. In addition, aluminum-based anodes have the advantages of being lightweight and having a low self-corrosion rate. Aluminum-based anodes also have the advantages of low environmental pollution and excellent environmental performance.

[0060] Reference Figure 1 As shown, the connecting device also includes an elastic buffer 500, which is disposed between the second connector 200 and the third connector 300, and the elastic buffer 500 is connected to the second connector 200 and the third connector 300 through the first connector 100.

[0061] In this embodiment, the elastic buffer 500 can absorb the impact energy received by the first connector 100. In the marine environment, the float is often affected by wind and waves or other dynamic loads. These external forces may cause vibration or loosening between the second connector 200 and the third connector 300 and the first connector 100. The elastic buffer 500 converts the impact energy into heat energy or other forms of energy release through its own deformation capacity, thereby reducing the direct impact on the first connector 100. In addition, the presence of the elastic buffer 500 makes the connection have a certain degree of flexibility, which can adapt to the relative displacement between the floats within a certain range, which helps to maintain the tightness of the connection and prevents loosening or failure caused by changes in the external environment (such as temperature fluctuations, water flow impact, etc.). Furthermore, under dynamic load conditions, the first connector 100, the second connector 200 and the third connector 300 may frequently contact and rub against each other, resulting in wear. The elastic buffer 500 can act as an isolation layer to reduce the direct contact between the first connector 100, the second connector 200 and the third connector 300, thereby reducing the risk of wear.

[0062] Specifically, in this embodiment, the elastic buffer 500 is made of natural rubber, neoprene rubber, or polyurethane material. Natural rubber, neoprene rubber, and polyurethane material all have the advantages of high wear resistance, high strength, and high chemical resistance.

[0063] This application provides a marine floating device, including the aforementioned connecting device.

[0064] In the marine floating equipment of this application, since the above-mentioned connecting device can simplify the connection method of the floating body, the marine floating equipment of this application has a simpler installation process and a shorter construction period, thereby reducing the installation difficulty of the marine floating equipment.
