Description

Technical Field

[0001] This utility model relates to the field of marine engineering corrosion prevention technology, and in particular to a remote auxiliary anode device for marine engineering. Background Technology

[0002] Corrosion protection of underwater metal structures is one of the core challenges in marine engineering. Cathodic protection technology inhibits electrochemical corrosion by providing cathodic current to the protected structure, shifting its potential negative to the range where corrosion reactions cease. Remote auxiliary anodes, as key equipment in this technology, must continuously release protective current in areas far from the protected structure; their performance directly determines the corrosion protection effect and maintenance costs.

[0003] Currently, the mainstream remote auxiliary anode devices in the industry, such as the "A Remote Suspended Impressed Current Anode Device and Its Usage Method" (publication number CN103806006A), adopt a suspended auxiliary anode structure design, connected to a cable below the base. Its drawbacks include: under the action of water flow, the connecting cable will experience fatigue due to the anode's swaying; the cable will also shake and rub against other structures, easily damaging the insulation layer and causing short circuits or wire breakage; simultaneously, the suspension support is made of foamed polyethylene material, which is prone to swelling and aging after long-term immersion, leading to buoyancy reduction and affecting the protection effect; the gaps in the anti-trapping cage are relatively large, and fishing nets still pose a risk of scraping the anode, causing the equipment to overturn or the anode to fail. The existing "A Remote Auxiliary Anode" (publication number CN211921700U) uses an inner shield + outer shield + staggered strip-shaped through-hole design, which has a fatal flaw in high-sand-content sea areas. After water flow carries sediment into the gaps of the shield, it is difficult to be flushed out by the reverse water flow, clogging the channels and reducing the protection effect. Therefore, further improvements are needed to the remote auxiliary anode. Utility Model Content

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] A remote auxiliary anode device for marine engineering, combined with Figures 1-13As shown, the device includes: an anti-sinking plate 1, a central column 2, and two or more support columns 3. An anode mounting base 4 is supported at the upper end of the central column 2 and support columns 3. The anode mounting base 4 is pyramidal in shape, and an anode disk 5 is provided on the side of the anode mounting base 4. The anode disk 5 is electrically connected to a branch cable 61 of a cable 6, which extends out of the bottom surface of the anode mounting base 4. This application uses a pyramidal anode mounting base 4, with an anode disk 5 on its outer side, and a branch cable 61 connecting the anode disk 5. The anode disk 5 is tightly attached to the outer wall of the pyramidal anode mounting base 4, eliminating any areas prone to hooking or scraping, thus preventing fishing nets from rubbing against the anode disk 5. Furthermore, the exposed anode disk 5 has a closed structure, eliminating the need for gaps for water flow and avoiding the influence of silt. The structure formed by the anti-sinking plate 1, central column 2, support column 3, anode mounting base 4, anode disc 5, and cable 6 works together to: First, ensure that the anode is submerged in water, preventing cable 6 from swaying and causing fatigue; Second, better reduce the risk of fishing nets rubbing against the anode, thus preventing the device from tipping over or the anode from failing, and can be directly applied to nearshore areas with frequent fishing activities; Finally, the installation of the anode disc 5 is simpler, eliminating concerns about silt entering the gaps, avoiding localized corrosion caused by debris accumulation, extending the equipment maintenance cycle, and better adapting to the environment of sea areas with high sediment content.

[0039] Preferably, the anode mounting base 4 is shaped like a regular pyramid, and each side of the anode mounting base 4 is provided with an anode disk 5, which can improve the protection capability of the device.

[0040] Specifically, the anode disk 5 is triangular in shape and is a titanium-based MMO-plated anode (or other equivalent anodes, such as platinum-niobium-plated anodes). A protective current is released through the electrochemical reaction of the MMO coating, causing cathodic polarization of the protected metal structure and inhibiting corrosion. During operation, a protective current is continuously released into the surrounding seawater, forming a circuit through the protected object and the potentiostat. It can be understood that the anode disk 5 can be replaced with other planar shapes to adapt to the installation position and shape of the anode mounting base 4 and to provide a conformal seal.

[0041] Preferably, the number of support columns 3 is the same as the number of edges of the anode mounting base 4, and the support columns 3 and the edges of the anode mounting base 4 correspond one-to-one. In this embodiment, the anode mounting base 4 is a regular square pyramid. There are also four support columns 3. The anti-sinking plate 1, support columns 3, and anode mounting base 4 form a pyramid-shaped main frame. The main frame has no sharp edges, and the anode plate 5 is installed according to the shape of the main frame, effectively reducing the risk of fishing net snagging.

[0042] Preferably, the anode plate 5 includes a plate 51 and a connecting post 52 fixed on the plate 51. The connecting post 52 passes through the side of the anode mounting base 4 and enters the cavity of the anode mounting base 4. The connecting post 52 is electrically connected to the branch cable 61. The connecting post 52, the anode mounting base 4, and the branch cable 61 are sealed by the first sealing component.

[0043] Specifically, the outer wall of the anode mounting base 4 has a groove adapted to the shape of the anode disk 5, allowing the anode disk 5 to be lower than the outer surface of the anode mounting base 4. An anode mounting hole is formed at the center of the side of the anode mounting base 4, through which the connecting post 52 passes. The cooperation between the connecting post 52 and the first sealing component enables the installation of the anode disk 5 and ensures the sealing of the anode mounting base 4, guaranteeing that the angle error between the anode disk 5 and the outer wall of the anode mounting base 4 after installation is ≤0.5°.

[0044] Preferably, the first sealing component includes: a first sealing gasket 71, a first sealing seat 72, a first sealing sleeve 73, and a first compression cap 74. The first sealing gasket 71 is sleeved on the connecting post 52. The end of the first sealing seat 72 presses the first sealing gasket 71 against the inner wall of the anode mounting base 4. The connecting post 52 passes through the central hole of the first sealing seat 72. The first sealing sleeve 73 is located inside the first sealing seat 72, and the first sealing sleeve 73 and the first sealing seat 72 are in a tapered fit. The first compression cap 74 is located at the end of the first sealing sleeve 73 away from the connecting post 52. The first compression cap 74 is threadedly connected to the first sealing seat 72. The branch cable 61 passes through the first compression cap 74 and the first sealing sleeve 73 and is electrically connected to the connecting post 52. Tightening the first compression cap 74 compresses the first sealing sleeve 73, causing the first sealing sleeve 73 to deform and make tight contact with the first sealing seat 72 and the branch cable 61. After the first sealing gasket 71 is compressed, the first sealing seat 72 and the anode mounting seat 4 are sealed, and the first sealing sleeve 73 seals the branch cable 61 and the first sealing seat 72.

[0045] Preferably, the center hole of the first sealing seat 72 is provided with a first internal thread 721 at one end facing the connecting column 52 and a second internal thread 722 at the other end. The center hole of the first sealing seat 72 is also provided with a first mating part 723. The first mating part 723 is provided with a first conical surface 724. The diameter of the first conical surface 724 gradually increases along the direction from the first internal thread 721 to the second internal thread 722.

[0046] The connecting post 52 is provided with a first external thread 523, which mates with the first internal thread 721 to achieve a tightening connection and sealing between the first sealing seat 72 and the connecting post 52;

[0047] The first sealing sleeve 73 has a first sealing sleeve through hole 731 in the middle and a second conical surface 732 on the outer periphery. The second conical surface 732 and the first conical surface 724 are engaged. After the first sealing sleeve 73 is squeezed, the second conical surface 732 is pressed on the first conical surface 724, the first sealing sleeve through hole 731 is deformed, and the inner wall is squeezed on the outer periphery of the branch cable 61.

[0048] The first clamping cap 74 has a first clamping cap through hole 741 in the middle and a second external thread 742 on its outer periphery. The second external thread 742 mates with the second internal thread 722 to achieve a tightening connection and seal between the first sealing seat 72 and the first clamping cap 74. The first clamping cap through hole 741 allows the branch cable 61 to pass through and prevents the branch cable 61 from twisting when the first clamping cap 74 is tightened.

[0049] Preferably, the first sealing component further includes a first anti-friction pad 75, which is located between the first compression cap 74 and the first sealing sleeve 73. The branch cable 61 passes through the wire hole 741 of the first compression cap, the first anti-friction pad 75, and the wire hole 731 of the first sealing sleeve. Since the first sealing sleeve 73 is made of elastic material and the first compression cap 74 is made of metal, the contact point between the two may wear down the branch cable 61. Therefore, by adding the first anti-friction pad 75, direct contact between the branch cable 61 and the port of the wire hole 741 of the first compression cap is avoided, and the port of the wire hole 741 of the first compression cap is rounded. The first sealing component achieves a complete seal after the branch cable 61 is connected to the connecting post 52, preventing seawater intrusion that could lead to short circuits or anode failure.

[0050] Understandably, the first sealing component could also be replaced with a sealed oil tank design, with insulating sealing oil added inside. This would balance the pressure inside and outside the oil tank during deep-sea operations, extending the service life of the equipment.

[0051] Preferably, the connecting column 52 includes a light column section 521 fixed on the plate 51 and a threaded section located at the end of the light column section 521. The threaded section has a first external thread 523, and a sealing ring groove 522 is formed on the outer periphery of the light column section 521. An anode mounting hole is formed on the side of the anode mounting seat 4, and a sealing ring is provided in the sealing ring groove 522 and cooperates with the inner wall of the anode mounting hole to further improve the sealing performance.

[0052] Specifically, the threaded end of the connecting post 52 is fixed with an electrical connection part, and the electrical connection part is provided with a through hole. The electrical connection part is fixedly connected to the terminal of the branch cable 61 head by bolts.

[0053] Preferably, after the cable 6 passes through the bottom surface of the anode mounting base 4, it is sealed by a second sealing component. The second sealing component includes: a second sealing gasket 81, a second sealing seat 82, a second sealing sleeve 83, and a second compression cap 84. The second sealing gasket 81 is fitted onto the second sealing seat 82, and the end of the second sealing seat 82 presses the second sealing gasket 81 against the bottom surface of the anode mounting base 4. The second sealing seat 82 is threadedly connected to the cable through hole at the bottom of the anode mounting base 4. The second sealing sleeve 83 is located inside the second sealing seat 82, and the second sealing sleeve 83 and the second sealing seat 82 are fitted with a tapered surface. The second compression cap 84 is located at the end of the second sealing sleeve 83 away from the anode mounting base 4, and the second compression cap 84 is threadedly connected to the second sealing seat 82. The cable 6 passes through the second compression cap 84 and the second sealing sleeve 83. Tightening the second compression cap 84 compresses the second sealing sleeve 83, causing the second sealing sleeve 83 to deform and make tight contact with the second sealing seat 82 and the cable 6. After the second sealing gasket 81 is compressed, the second sealing seat 82 and the bottom surface of the anode mounting seat 4 are sealed, and the second sealing sleeve 83 seals the cable 6 and the second sealing seat 82.

[0054] Specifically, the second sealing seat 82 has a third external thread 821 at one end facing the anode mounting seat 4 and a fourth internal thread 822 in the center hole at the other end. The center hole of the second sealing seat 82 also has a second mating part 823. The second mating part 823 has a third conical surface 824. The diameter of the third conical surface 824 gradually increases along the direction from the third external thread 821 to the fourth internal thread 822.

[0055] The cable through hole is provided with a third internal thread, which mates with the third external thread 821 to achieve a tight connection and seal between the second sealing seat 82 and the bottom surface of the anode mounting seat 4;

[0056] The second sealing sleeve 83 has a second sealing sleeve through hole 831 in the middle and a fourth conical surface 832 on the outer periphery. The fourth conical surface 832 and the third conical surface 824 are engaged. After the second sealing sleeve 83 is squeezed, the fourth conical surface 832 is pressed on the third conical surface 824, the second sealing sleeve through hole 831 is deformed, and the inner wall is squeezed on the outer periphery of the cable 6.

[0057] The second clamping cap 84 has a wire hole 841 in the middle and a fourth external thread 842 on its outer circumference. The fourth external thread 842 mates with the fourth internal thread 822 to achieve a tight connection and seal between the second sealing seat 82 and the second clamping cap 84. The wire hole 841 allows the cable 6 to pass through and prevents the cable 6 from twisting when the second clamping cap 84 is tightened.

[0058] Preferably, the second sealing component further includes a second anti-friction pad 85, which is located between the second clamping cap 84 and the second sealing sleeve 83. The cable 6 passes through the wire hole 841 of the second clamping cap, the second anti-friction pad 85, and the wire hole 831 of the second sealing sleeve.

[0059] Specifically, the four branch cables 61 are integrated into one cable 6, and the joint of cable 6 is treated with rubber vulcanization to ensure sealing. The main sealing points of this application are the connecting post 52 of the anode disk 5 and the joint of cable 6. The two seals are achieved by the first sealing component and the second sealing component, respectively, and the sealing level can reach more than 6MPa, which can meet the design requirements of most existing marine engineering fields.

[0060] Preferably, the bottom surface of the anode mounting base 4 is fixedly provided with an auxiliary central connecting column 43 and an auxiliary oblique connecting column 44. The top end of the auxiliary central connecting column 43 is fixedly connected to the bottom surface of the anode mounting base 4, and the bottom end is inserted into the central column 2 and fixed. The number of auxiliary oblique connecting columns 44 is the same as the number of support columns 3 and corresponds one-to-one. The top end of the auxiliary oblique connecting column 44 is fixedly connected to the bottom surface of the anode mounting base 4, and the bottom end is inserted into the support column 3 and fixed.

[0061] The support column 3 is connected to the central column 2 by a first connecting rod 91, and two adjacent support columns 3 are connected by a second connecting rod 92. The auxiliary central connecting rod 43 and the auxiliary oblique connecting rod 44 can be used to easily connect the anode mounting base 4, the support column 3, and the central column 2, and the first connecting rod 91 and the second connecting rod 92 can be used to connect each support column 3 and the central column 2 into one unit, increasing the stability of the structure.

[0062] Specifically, the auxiliary connecting column 43 and the central column 2 have corresponding connecting holes. One end of the first connecting rod 91 passes through the connecting holes of the central column 2 and the auxiliary connecting column 43 and enters the central hole of the auxiliary connecting column 43. The auxiliary inclined connecting column 44 and the support column 3 have corresponding connecting holes. One end of the first connecting rod 91 passes through the connecting holes of the support column 3 and the auxiliary inclined connecting column 44 and enters the central hole of the auxiliary inclined connecting column 44. One end of the second connecting rod 92 passes through the connecting holes of the support column 3 and the auxiliary inclined connecting column 44 and enters the central hole of the auxiliary inclined connecting column 44, and the other end passes through the connecting holes of the adjacent support column 3 and the auxiliary inclined connecting column 44. The central column 2 and the support column 3 are made of carbon steel, while the auxiliary connecting column 43 and the auxiliary inclined connecting column 44 are made of FRP (glass fiber reinforced epoxy resin). The auxiliary connecting column 43 and the central column 2 are fixed by adhesive bonding, the auxiliary inclined connecting column 44 and the support column 3 are fixed by adhesive bonding, and the first connecting rod 91 and the second connecting rod 92 are fixed by welding.

[0063] Specifically, two sacrificial anode blocks are pre-installed on the support column 3 to prevent corrosion of the equipment after the metal materials are submerged. Lifting lugs are welded to the support column 3 for hoisting; after hoisting, it can be cut underwater to avoid protruding from the support column 3. The anti-sinking plate 1 uses a concrete base, and the bottoms of the support column 3 and the central column 2 are fixed to the concrete base with bolts. Compared to materials such as 316L and titanium alloy, the materials used in this application are low-cost and have good corrosion resistance. The corrosion rate of FRP material in 3.5% NaCl solution approaches 0, reducing the frequency of maintenance throughout the device's life cycle and facilitating product promotion.

[0064] The device uses its own weight to contact the seabed (or seabed) via a flat concrete base, which increases the contact area with the seabed, ensuring structural stability and preventing the device from shifting under the action of water flow and waves, thus fixing the device in the preset position.

[0065] The aforementioned advantages of this application make its application scenarios very broad, and it can be applied to underwater metal structure cathodic protection products in the field of marine engineering, specifically including:

[0066] Offshore oil and gas platforms provide corrosion protection for the steel pile foundations of offshore oil platforms;

[0067] Submarine pipelines are used for cathodic protection of submarine oil and gas pipelines to prevent seawater corrosion and perforation.

[0068] Offshore wind turbine foundations provide corrosion protection for the underwater steel foundations (such as monopiles and jackets) of offshore wind turbine towers.

[0069] Corrosion protection of metal structures in underwater buildings, such as seabed observation stations and underwater production facilities.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
