Description

Technical Field

[0001] This invention relates to the field of corrosion protection, and more particularly to a socket-type sacrificial anode device and its installation method. Background Technology

[0002] Offshore platforms often use steel structures as their supporting foundations, such as oil drilling platforms, offshore ships, offshore substations, deep-sea aquaculture cages, offshore wind power foundations, and navigation buoys. Corrosion protection for underwater steel structure supporting foundations often involves adding sacrificial anode blocks.

[0003] Current sacrificial anodes are typically installed and fixed using methods such as welding, direct fastening with fasteners, or mechanical structural component compression. Since welding of marine structures in prefabrication yards is often performed at high altitudes, welding sacrificial anodes at such heights is extremely inconvenient. Furthermore, the non-replaceability of welding methods has led to their gradual abandonment, and fastener or mechanical structural component fixation has become increasingly accepted. However, direct fastening involves the fasteners directly bearing vertical shear forces and requires strict tightening torque; mechanical structural components are complex, costly to manufacture, and pose a risk of loosening and detachment under strong vibrations. Therefore, there is an urgent need to develop a sacrificial anode device that is simple in structure, low in manufacturing cost, quick to install, and allows for free switching between on and off states. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a socket-type sacrificial anode device and its installation method, which aims to solve the problems of sacrificial anodes in the prior art that are complex in structure, high in cost and troublesome in installation.

[0005] The technical solution adopted by this invention to solve its technical problem This invention provides an installation method for a socket-type sacrificial anode device. The socket-type sacrificial anode device includes a base assembly, an anode assembly, and a terminal assembly. The base assembly includes an upper base disposed above the anode assembly and a lower base disposed below the anode assembly. The anode assembly includes a sacrificial anode and connecting rods extending from both ends of the sacrificial anode in a direction away from the sacrificial anode. The terminal assembly includes terminals and fasteners. The terminals are respectively connected to both ends of the connecting rods via the fasteners. The installation method of the socket-type sacrificial anode device includes the following steps: Step S1: Calculate the area S that the facility needs to protect, and select the size and quantity of sacrificial anodes; Step S2: Calculate the dimensions of the upper and lower bases. Using stress analysis, simulate the shear force borne by the selected sacrificial anode when it is vertically installed on the lower base, thereby calculating the minimum suitable dimensions of the lower base. The upper base is based on the dimensions of the lower base. Step S3: Calculate the size and thickness of the retaining ring, and select the appropriate type of retaining ring; Step S4: Calculate the distance L between the upper and lower bases, the long end L1 and short end L3 of the connecting rod, and the total length L of the connecting rod, and select the appropriate connecting rod type. Step S5: Weld the upper base and the lower base to the facility at a distance L; attach the second insulating sleeve to the short end of the connecting rod; insert the long end of the connecting rod into the upper base; insert the second insulating sleeve into the lower base; attach the first insulating sleeve to the long end of the connecting rod and fix it inside the upper base; attach the third insulating sleeve from the lower base to the short end of the connecting rod. Step S6: The wiring terminals are connected to both ends of the connecting rod by fasteners. The wiring terminals and the docking assembly are connected by a composite cable to complete the installation of the anode body.

[0006] In some embodiments, the method for selecting the size and quantity of sacrificial anodes in step S1 is as follows: refer to the structural diagram of the long strip sacrificial anode for port facilities and seawater cooling systems in standard GB / T4948-2002, find the appropriate model of sacrificial anode for port facilities, record the width and thickness of the connecting rod of the sacrificial anode of that model, and calculate the required number of sacrificial anodes of that model.

[0007] In some embodiments, the method for designing the lower base dimensions in step S2 is as follows: the lower base mainly consists of a cladding plate, stiffening plates, and mounting rings; stress analysis is used to simulate the shear force borne by the stiffening plates and mounting rings of the lower base when the selected sacrificial anode is vertically installed on the lower base, thereby calculating the minimum suitable dimensions of the lower base, including the outer diameter of the mounting ring, the inner diameter of the mounting ring, the vertical length of the weld between the mounting ring and the stiffening plate (i.e., the height of the mounting ring), and the distance between the center of the mounting ring and the cladding plate.

[0008] In some embodiments, the extension length of the connecting rod near the upper base is greater than the extension length of the connecting rod near the lower base, the end of the connecting rod near the upper base is the long end, and the end of the connecting rod near the lower base is the short end.

[0009] In some embodiments, the connecting rod is in the shape of a long plate, and the first insulating sleeve, the second insulating sleeve and the third insulating sleeve are all provided with through holes that match the shape of the connecting rod, and a retaining ring is provided between the anode assembly and the second insulating sleeve.

[0010] In some embodiments, the lower base has a protrusion near the second insulating sleeve, and the second insulating sleeve has a recess near the lower base that matches the shape of the protrusion.

[0011] In some embodiments, the anode device further includes a docking assembly comprising a heat shrink tubing, a composite cable, a cable sealing sleeve, an interface flange, an epoxy-sealed heat shrink sleeve, a cable protection tube, and a cable. The composite cable is connected to the terminal block. The heat shrink tubing wraps around the connection between the composite cable and the terminal block. The composite cable and the cable are crimped together and fixed at the crimping point by the interface flange assembly. The cable sealing sleeve wraps around the composite cable and connects to the interface flange. The epoxy-sealed heat shrink sleeve wraps around the cable. The cable protection tube wraps around the epoxy-sealed heat shrink sleeve and connects to the interface flange.

[0012] The present invention has the following advantages: the upper and lower bases are welded to the facility at a predetermined distance. The second insulating sleeve is fitted onto the lower part of the connecting rod. The long end of the connecting rod is then inserted into the upper base, and the second insulating sleeve is inserted into the lower base. The anode assembly is used to press the second insulating sleeve into the lower base for fixation. The first insulating sleeve is fitted onto the long end of the connecting rod and fixed in the upper base. The third insulating sleeve is fitted onto the short end of the connecting rod from the lower base. With the upper and lower ends of the connecting rod fixed, the anode assembly is also relatively fixed. When the user needs to replace it, they only need to move the anode assembly upwards to disengage the lower end of the connecting rod from the second and third insulating sleeves. Then, the anode assembly is rotated outwards with the upper base as the center to detach it from the upper base. The entire device has a simple structure, is easy to operate, and enables rapid installation, thus improving the user's work efficiency. Attached Figure Description

[0017] Figures 1 to 3This invention illustrates a socket-type sacrificial anode device according to some embodiments, which can be used for corrosion protection of steel structures in marine environments. The device includes a base assembly, an anode assembly 100, a mounting assembly, and a terminal assembly. The base assembly includes an upper base 200 disposed above the anode assembly 100 and a lower base 300 disposed below the anode assembly 100. The anode assembly 100 includes a sacrificial anode 110 and connecting rods 120 extending from both ends of the sacrificial anode 110 in a direction away from the sacrificial anode 110. The mounting assembly includes a first insulating sleeve 400 disposed on the upper base 200 and a terminal assembly 400 disposed on the lower base 200. The lower base 300 has a second insulating sleeve 410 near the anode assembly 100 and a third insulating sleeve 420 disposed on the lower base 300 away from the anode assembly 100. The terminal assembly includes a terminal block 500 and a fastener 510. The anode assembly 100 passes through the first insulating sleeve 400, the second insulating sleeve 410 and the third insulating sleeve 420 via the connecting rod 120. The first insulating sleeve 400 is disposed on the upper base 200, and the second insulating sleeve 410 and the third insulating sleeve 420 pass through the lower base 300. The terminal block 500 is connected to both ends of the connecting rod 120 via the fastener 510. The upper base 200 and lower base 300 are welded to the facility at a specified distance. The second insulating sleeve 410 is fitted under the connecting rod 120. The long end of the connecting rod 120 is then inserted into the upper base 200. The second insulating sleeve 410 is inserted into the lower base 300. The anode assembly 100 is used to press the second insulating sleeve 410 into the lower base 300 for fixation. The first insulating sleeve 400 is fitted onto the long end of the connecting rod 120 and fixed inside the upper base 200. The third insulating sleeve 420 is inserted from the lower base. The 300 is sleeved on the short end of the connecting rod 120. The upper and lower ends of the connecting rod 120 are fixed, and the anode assembly 100 is also relatively fixed. When the user replaces it, he only needs to move the anode assembly 100 upward so that the lower end of the connecting rod 120 is disengaged from the second insulating sleeve 410 and the third insulating sleeve 420. Then, the anode assembly 100 is rotated outward with the upper base 200 as the center, so that the anode assembly 100 can be detached from the upper base 200. The whole device has a simple structure, is easy to operate, and improves the user's work efficiency.

[0018] In some embodiments, the extension length of the connecting rod 120 near the upper base 200 is greater than the extension length of the connecting rod 120 near the lower base 300, the end of the connecting rod 120 near the upper base 200 is the long end, and the end of the connecting rod 120 near the lower base 300 is the short end.

[0019] In some embodiments, the connecting rod 120 may be in the shape of a long plate. Understandably, the sacrificial anode 110 is disposed on the wide side of the connecting rod 120, which can be used to improve the welding effect of the sacrificial anode 110 on the connecting rod 120.

[0020] In some embodiments of the socket-type sacrificial anode device, the first insulating sleeve 400, the second insulating sleeve 410, and the third insulating sleeve 420 are all provided with through holes 411 that match the shape of the connecting rod 120. Understandably, the through holes 411 are rectangular grooves that can be used to restrict the relative rotation between the anode assembly 100 and the first insulating sleeve 400, the second insulating sleeve 410, and the third insulating sleeve 420.

[0021] In some embodiments, the lower base 300 may include a protrusion 310 on the side of the lower base 300 near the second insulating sleeve 410.

[0022] In some embodiments, the second insulating sleeve 410 may include a recess 412 on the side near the lower base 300 that matches the shape of the protrusion 310. This recess 412 can be used to combine the protrusion 310 and the recess 412 to restrict the rotation of the second insulating sleeve 410 and the lower base 300, thereby preventing the anode assembly 100 from rotating.

[0023] In some embodiments, the socket-type sacrificial anode device may include a retaining ring 130 between the anode assembly 100 and the second insulating sleeve 410. The retaining ring 130 can be used to release the sacrificial anode 110 and the second insulating sleeve 410, thereby reducing wear on the sacrificial anode 110.

[0024] Please see Figure 3 and Figure 4 In some embodiments, the socket-type sacrificial anode device may include a docking assembly comprising a heat-shrink tubing 520, a composite cable 530, a cable sealing sleeve 540, an interface flange 550, an epoxy-sealed heat-shrink sleeve 570, a cable protection tube 560, and a cable 580. The composite cable 530 is connected to the terminal block 500. The heat-shrink tubing 520 wraps around the connection between the composite cable 530 and the terminal block 500. The composite cable 530 and the cable 580 are crimped together and fixed at the crimping point by the interface flange 550. The cable sealing sleeve 540 wraps around the composite cable 530 and connects to the interface flange 550. The epoxy-sealed heat-shrink sleeve 570 wraps around the cable 580. The cable protection tube 560 wraps around the epoxy-sealed heat-shrink sleeve 570 and connects to the interface flange 550.

[0025] Please see Figure 8In some embodiments, the socket-type sacrificial anode device may include a vertical single-line arrangement, a ring arrangement, and a reserved base arrangement. The vertical single-line arrangement is a number of anode components 100 arranged in a straight line. The ring arrangement is a number of anode components 100 arranged in a circular array around the component. The reserved base arrangement includes a vertical single-line arrangement and a ring arrangement. After the anode group 100 pieces are installed, the sacrificial anode is not installed again, but is installed when needed.

[0026] Please see Figure 6 This invention relates to a control system for a socket-type sacrificial anode device in some embodiments, comprising a switching switch, an operating platform 600, and a cable 580. The operating platform 600 is located on the upper part of the facility, and the switching switch is located inside the operating platform 600. The switching switch is connected to the anode assembly 100 via the cable 580. This sacrificial anode control system differs from conventional underwater direct-conduction steel structure systems. This device can achieve the conduction of the sacrificial anode system on the sea surface by freely switching the on / off state of the cable. Especially when used in conjunction with ICCP protection, after the ICCP is put into operation, workers only need to disconnect the sacrificial anode cable within the platform using the switching switch to complete the disconnection of the sacrificial anode system, thereby ensuring the independent operation of the ICCP system.

[0027] Please see Figure 5 and Figure 7 This is an installation method for a socket-type sacrificial anode device in some embodiments of the present invention, comprising the following steps: Step S1: Calculate the area S that the facility needs to protect, and select the size and quantity of sacrificial anodes 110; Step S2: Calculate the dimensions of the upper base 200 and the lower base 300. Using stress analysis, simulate the shear force borne by the selected sacrificial anode 110 when it is vertically installed on the lower base 300, and thus calculate the minimum suitable size of the lower base 300. The upper base 200 is based on the size of the lower base 300. Step S3: Calculate the dimensions and thickness of the retaining ring 130, and select the appropriate type of retaining ring 130; Step S4: Calculate the spacing L between the upper base 200 and the lower base 300, the long end L1 and short end L3 of the connecting rod 120, and the total length L of the connecting rod 120, and select the type of connecting rod 120. Step S5: Weld the upper base 200 and the lower base 300 to the facility at a distance L; attach the second insulating sleeve 410 to the short end of the connecting rod 120; insert the long end of the connecting rod 120 into the upper base 200; insert the second insulating sleeve 410 into the lower base 300; attach the first insulating sleeve 400 to the long end of the connecting rod 120 and fix it inside the upper base 200; attach the third insulating sleeve 420 from the lower base 300 to the short end of the connecting rod 120. Step S6: The terminal block 500 is connected to both ends of the connecting rod 120 by fasteners 510. The terminal block 500 is connected to the docking assembly by composite cable 530 to complete the installation of the anode body.

[0028] In some specific embodiments, step S1: Selection of sacrificial anode 110. By calculating the area S to be protected, and referring to the structural diagram of the long strip sacrificial anode 110 for port facilities and seawater cooling systems in standard GB / T4948-2002, a suitable model of sacrificial anode 110 for port facilities is selected. The width and thickness of the connecting rod 120 of the sacrificial anode 110 of this model are recorded, which is standard GB / T4948-2002. At the same time, the required number n of sacrificial anodes 110 under this model is calculated. Step S2: Calculate the dimensions of the upper base 200 and the lower base 300. The lower base 300 mainly consists of a cover plate 210, a stiffening plate 220, and a mounting ring 230. The socket-type sacrificial anode 110 is installed vertically. The lower base 300 is the main load-bearing base, and the upper base 200 is the auxiliary control base. Therefore, the dimensions of the upper base 200 and the lower base 300 can be consistent. Stress analysis was used to simulate the shear force borne by the stiffening plate 220 and mounting ring 230 of the lower base 300 when the selected sacrificial anode 110 was vertically installed on the lower base 300. This allowed for the calculation of the minimum suitable dimensions of the lower base 300, including the outer diameter Ø1 of the mounting ring 230, the inner diameter Ø2 of the mounting ring 230, the vertical length of the weld between the mounting ring 230 and the stiffening plate 220 (i.e., the height c of the mounting ring 230), and the distance L0 between the center of the mounting ring 230 and the cover plate 210. This ensured that the stiffening plate 220 of the upper base 200 and the connecting rod 120 did not interfere with the sacrificial anode 110 during socket installation, while preventing weld cracking in the lower base 300 during engineering applications. During design, the inner diameter Ø2 of the mounting ring 230 should be 2 to 3 times the width of the connecting rod 120 of the sacrificial anode 110. Step S3: Calculate the distance L2 between the outer surfaces of the retaining rings 130. The retaining rings 130 consist of upper and lower rings. The lower retaining ring 130 is the main load-bearing component, and its thickness h1 is calculated. Its diameter is consistent with the outer diameter Ø1 of the mounting ring 230. The upper retaining ring 130 mainly serves as the installation calibration reference and is not under load; its dimensions are consistent with the lower retaining ring 130. The distance L2 between the outer surfaces of the two retaining rings 130 is determined by the length A of the selected sacrificial anode 110. The value of A is the value in standard GB / T4948-2002. The distance between the inner surface of the retaining ring 130 and the end face of the sacrificial anode 110 is usually selected as 20mm. Therefore, the distance L2 between the outer surfaces of the retaining rings 130 = A + 2h1 + 40. Step S4: Calculate the distance L between the upper and lower bases 300, the long end L1 and short end L3 of the connecting rod 120, and the total length L. Insert the long end of the sacrificial anode 110 obliquely into the upper base mounting ring 230. At this time, the contact point between the bottom of the upper base mounting ring 230 and the retaining ring 130 is point P0. The center point of contact between the connecting rod 120 and the bottom of the mounting ring 230 is P1, and the center point of contact between the connecting rod 120 and the upper part of the mounting ring 230 is P2. Connect P1 and P2, and the intersection point O with the center line of the mounting ring 230 is point O. Draw a circle with center O and radius R0 around the socket-type sacrificial anode 110, which is tangent to the circle on the upper surface of the mounting ring 230 of the lower base 300. Figure 2 The calculation steps for the socket-type sacrificial anode 110 are shown in the diagram. At this point, the distance 'a' from the exposed insulating kit of the connecting rod 120 is used for installing the 500 bolts of the terminal block, typically around 30mm. The thickness 'b' of the insulating kit clamping plate is obtained from stress analysis; the thicknesses of the upper and lower insulating kit clamping plates are the same. The distance 'd' between the bottom surfaces of the 06 upper retaining ring 130 and the 03 upper base mounting ring 230 is manually measured.

[0029] Therefore, the base spacing L = 1 / 2 the thickness c of the upper base mounting ring 230 + the distance d between the bottom surface of the upper retaining ring 130 and the upper base mounting ring 230 + the spacing L2 between the upper and lower retaining rings 130 + the thickness b of the upper half of the insulation kit pressing sheet of the lower base 300 + 1 / 2 the thickness c of the lower base 300 mounting ring 230, that is: L = b + c + d + L2. Similarly... Figure 2 Step III: The long end dimension L1 of connecting rod 120 is a+b+c+d, the long end dimension L3 of connecting rod 120 is a+2b+c, and the total length L” of connecting rod 120 is L1+L2+L3=2a+3b+2c+d+L2.

[0030] It is understood that the above embodiments only illustrate preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of the present invention, and can also make several modifications and improvements, all of which fall within the protection scope of the present invention. Therefore, all equivalent transformations and modifications made with respect to the scope of the claims of the present invention should fall within the scope of the claims of the present invention.
