Description

Technical Field

[0001] This utility model relates to the field of sacrificial anodes, and more particularly to aluminum alloy sacrificial anodes for marine applications. Background Technology

[0002] Aluminum alloy sacrificial anodes are metallic materials made based on the principle of electrochemical corrosion. They are industrial products that provide protection for the cathode metal structure through their own corrosion. Their electrode potential is more negative than that of the protected metal. In an electrolyte environment, they preferentially dissolve and release electrons, inhibiting cathode corrosion. They are suitable for the protection of ships, marine engineering facilities, and pipelines and cables in seawater media.

[0003] The prior art patent application with publication number CN218858657U describes a method where, during the ship's movement, the friction between the baffle and seawater causes the baffle to rotate a roller. The baffle remains in contact with the curved plate throughout this rotation, preventing seawater from entering. Simultaneously, corroded sacrificial anodes slide along the surface of the inclined plate and converge at the roller. The rotation of the roller and baffle removes the corrosion, preventing seawater contamination from affecting the anode's performance. By moving and pressing the L-shaped connector, two sliding plates move towards each other. The return spring is compressed, aligning the L-shaped connector's insertion hole with the fixing rod. The return spring then rebounds the sliding plate, allowing the L-shaped connector to engage with the fixing rod, making the replacement and installation of sacrificial anodes more convenient.

[0004] However, when the baffles drive the drum to rotate to one side, the gaps between the multiple baffles on the drum will transport seawater into the interior of the installation tank and into contact with the sacrificial anode, thereby causing corrosion to the sacrificial anode.

[0005] Therefore, it is necessary to provide aluminum alloy sacrificial anodes for marine applications to solve the aforementioned technical problems. Utility Model Content

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

[0025] First Embodiment

[0026] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of the structure of the first embodiment of the aluminum alloy sacrificial anode for ships provided by this utility model; Figure 2 for Figure 1 The diagram shows a cross-sectional view of the protective box. Figure 3 for Figure 1 The enlarged schematic diagram of part A shown below; Figure 4 for Figure 2 The enlarged schematic diagram of section B is shown. The marine aluminum alloy sacrificial anode includes: a protective box 1, a sealing cover 2, a fixing block 3, a sealing element 4, a sacrificial anode 5, a positioning device 6, a collection tank 7, a collection frame 8, and a fixing element 9;

[0027] The sealing cover 2 is disposed on one side of the protective box 1, one side of the fixing block 3 is fixedly connected to one side of the sealing cover 2, and the sealing element 4 is disposed inside the protective box 1;

[0028] The sacrificial anode 5 is disposed inside the protective box 1, the positioning device 6 is disposed inside the protective box 1, the collection groove 7 is opened inside the protective box 1, and the fixing member 9 is disposed inside the sealing cover 2.

[0029] The sealing element 4 is a sealing gasket used to seal the space between the sealing cover 2 and the protective box 1.

[0030] The fastener 9 is a bolt. Both the sealing cover 2 and the protective box 1 have threaded holes that are compatible with the bolts. This is used to fix the sealing cover 2 and the protective box 1 after the bolts are installed into the threaded holes.

[0031] Two collection boxes 8 are used to collect the corroded sacrificial anodes 5 for easy cleaning later.

[0032] The sealing element 4 is a sealing ring, and one side of the sealing ring is fixedly connected to one side of the sealing cover 2.

[0033] The sealing ring is used to seal the space between the sealing cover 2 and the protective box 1.

[0034] The positioning device 6 includes multiple positioning slots 61, multiple positioning blocks 62, two positioning frames 63, and two reset members 64. The multiple positioning slots 61 are all opened inside the protective box 1. The multiple positioning blocks 62 are slidably connected to the interior of the multiple positioning slots 61. The two positioning frames 63 are slidably connected to the interior of the protective box 1. The two reset members 64 are respectively disposed on one side of the two positioning frames 63.

[0035] The reset element 64 is a spring, which is used to push the positioning frame 63 to move to one side.

[0036] The positioning device 6 also includes four guide blocks 65, the bottoms of which are fixedly connected to the top ends of the two positioning frames 63 respectively.

[0037] After the sacrificial anode 5 is inserted into the protective box 1, and the bottom of the sacrificial anode 5 contacts the surfaces of the two positioning frames 63, the sacrificial anode 5 presses the two positioning frames 63 to move to one side, thereby driving multiple positioning blocks 62 to move to one side in the multiple positioning slots 61 respectively. At the same time, when the positioning frames 63 move to one side, they press the reset member 64. After the sacrificial anode 5 is inserted into the protective box 1, the reset member 64 pushes the positioning frames 63 to move to one side to reset, thus limiting the sacrificial anode 5.

[0038] Multiple guide blocks 65 are used for guiding and positioning as the sacrificial anode 5 moves downward.

[0039] The reset component 64 is a spring clip, one end of which is fixedly installed on one end of the positioning frame 63, and the other end is fixedly installed on the inner wall surface of the protective box 1.

[0040] The protective box 1 is provided with a limiting device 10 inside. The limiting device 10 includes two limiting grooves 101 and two limiting blocks 102. The two limiting grooves 101 are opened inside the protective box 1, and the two limiting blocks 102 are slidably connected to the inside of the two limiting grooves 101 respectively.

[0041] One side of each of the two limiting blocks 102 is fixedly connected to both ends of one side of the sealing cover 2. When installing the sealing cover 2, the two limiting blocks 102 on one side of the sealing cover 2 are inserted into the two limiting grooves 101 respectively, and then the fixing member 9 is installed. This reduces the use of the fixing member 9 and makes it easier to install the sealing cover 2.

[0042] The working principle of the aluminum alloy sacrificial anode for marine applications provided by this utility model is as follows:

[0043] In use, after inserting the sacrificial anode 5 into the interior of the protective box 1, the positioning device 6 limits the sacrificial anode 5, and then the fixing block 3 on one side of the sealing cover 2 is inserted into the interior of the protective box 1 to limit the sacrificial anode 5. Finally, the fixing piece 9 is installed to limit the distance between the sealing cover 2 and the protective box 1.

[0044] The corroded sacrificial anodes 5 will enter the collection tank 7 and then enter the collection frame 8. The collection frame 8 will collect the corroded sacrificial anodes 5 for easy cleaning later.

[0045] Compared with related technologies, the aluminum alloy sacrificial anode for ships provided by this utility model has the following beneficial effects:

[0046] This utility model provides an aluminum alloy sacrificial anode for ships. The sacrificial anode 5 is protected by a protective box 1, a sealing cover 2, and a sealing element 4, thereby preventing seawater from contacting the sacrificial anode 5 and causing corrosion. At the same time, the sacrificial anode 5 is fixed by the sealing cover 2 and the fixing block 3, and the positioning device 6 positions and initially limits the sacrificial anode 5, thereby facilitating the installation of the sacrificial anode 5.

[0047] Second Embodiment

[0048] Please refer to the following: Figure 5 Based on the first embodiment of this application providing a sacrificial aluminum alloy anode for marine applications, the second embodiment of this application proposes another sacrificial aluminum alloy anode for marine applications. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0049] Specifically, the difference in the second embodiment of this application for marine aluminum alloy sacrificial anode is that it also includes a limiting member 11 inside the protective box 1, and a moving device 12 inside the limiting member 11.

[0050] The limiting component 11 is a threaded cover. The inside of the protective box 1 is provided with a threaded hole that matches the threaded cover. One end of the threaded cover is rotatably connected to one end of the collection frame 8 to facilitate the installation and removal of the collection frame 8.

[0051] The moving device 12 has a concave handle, which is opened inside the limiting member 11. The concave handle is used to facilitate the installation of the limiting member 11.

[0052] The working principle of the aluminum alloy sacrificial anode for marine applications provided by this utility model is as follows:

[0053] In use, by rotating the moving device 12 to one side, the limiting member 11 is rotated to one side, and the limiting member 11 is moved and separated to one side inside the protective box 1. The limiting member 11 is then pulled to one side, causing the collection frame 8 to move to one side. After it is moved to one side inside the protective box 1 and removed, the collection frame 8 can be disassembled.

[0054] When installing the collection frame 8, after inserting the collection frame 8 into the protective box 1, the moving device 12 is rotated to one side, thereby causing the limiting member 11 to rotate to one side, so that the limiting member 11 moves to one side inside the protective box 1 to fix the collection frame 8.
