Description

Technical Field

[0001] The utility model relates to the technical field of sacrificial anode anti-corrosion, in particular to an aluminum alloy sacrificial anode anti-corrosion mechanism for ships. Background Art

[0002] Sacrificial anode is a method to prevent metal corrosion. It uses a metal with strong reducing properties (such as aluminum alloy) as a protective electrode to connect with the protected metal to form a primary battery. The metal with strong reducing properties is consumed by oxidation reaction as the negative electrode, and the protected metal is used as the positive electrode to avoid corrosion.

[0003] In order to improve the working performance of sacrificial anodes, a Chinese utility model patent with publication number "CN218858657U" discloses an aluminum alloy sacrificial anode anti-corrosion mechanism for ships, including a hull, a through installation groove is provided on the bottom surface of the hull, and an anti-corrosion component is arranged inside the installation groove, and the anti-corrosion component includes: a sacrificial anode, a steel core is fixedly connected to the inside of the sacrificial anode, and both ends of the steel core are penetrated and slidably connected to the inside of the sleeve. The aluminum alloy sacrificial anode anti-corrosion mechanism for ships, when the hull is traveling, the baffle plate generates friction with the seawater, so that the baffle plate drives the roller to rotate, and the baffle plate always keeps in contact with the arc plate during the rotation process, thereby avoiding the entry of seawater, and at the same time, the corroded sacrificial anode slides along the surface of the inclined plate and gathers to the position of the roller, and the corrosion products are discharged through the rotation of the roller and the baffle plate, thereby avoiding the influence of the pollution degree of seawater, which may affect the working performance of the anode;

[0004] However, in actual use, we found that in order to avoid the influence of corrosive substances on the working performance of the anode in the above scheme, the corrosive substances are discharged into the sea water through a drum and a baffle. However, in real life, directly discharging corrosive substances into the sea water will have a great impact on the ecological health of marine organisms. At the same time, the corrosive substances on the upper end of the sacrificial anode in the above scheme will always cover the upper end of the sacrificial anode due to the lack of external force, thereby affecting the working performance of the sacrificial anode. Therefore, in order to solve these problems, we need to consider designing an aluminum alloy sacrificial anode anti-corrosion mechanism for ships. Utility Model Content

[0022] The movable cleaning mechanism is also included, and the movable cleaning mechanism is used to scrape off the oxidized corrosion products on the upper end of the aluminum alloy sacrificial anode body 8. The movable cleaning mechanism includes a motor 11 installed on the right side of the housing 1, and the motor 11 is a servo motor that can change the rotation direction. A threaded rod 12 is rotatably connected between the left and right inner walls of the housing 1, and a second connecting block 13 is threadedly connected to the threaded rod 12. A guide rod 14 is fixedly connected between the left and right inner walls of the housing 1, and the guide rod 14 passes through the second connecting block 13. A brush 15 is installed at the lower end of the second connecting block 13, and the brush 15 can scrape off the oxidized corrosion products on the upper end of the aluminum alloy sacrificial anode body 8;

[0023] It also includes an alarm mechanism, which is used to remind the staff to replace the aluminum alloy sacrificial anode body 8 in time. The alarm mechanism includes a trigger block 16 fixedly connected to the upper end of the support plate 4, and a third connecting block 17 is fixedly connected to the inner wall of the shell 1. A button 18 is installed at the lower end of the third connecting block 17. The trigger block 16 and the button 18 cooperate with each other. When the aluminum alloy sacrificial anode body 8 needs to be replaced, the trigger block 16 will move up and contact the button 18, thereby triggering the alarm 19 to remind the staff to replace it in time. The alarm 19 is installed on the right side of the shell 1, and the button 18 and the alarm 19 are electrically connected.

[0024] In the present utility model, in actual use, oxidized corrosion products will form on the surface of the aluminum alloy sacrificial anode body 8 and fall off, wherein the oxidized corrosion products on the four sides and the inner bottom of the aluminum alloy sacrificial anode body 8 will pass through the multiple recovery holes 6 and fall into the recovery box 10 along the guidance of the guide plate 9, and the oxidized corrosion products on the upper end of the aluminum alloy sacrificial anode body 8 need to be periodically brushed off with the help of the brush 15, and the control motor 11 is periodically started, and each time it is started, it will drive the threaded rod 12 to rotate, and drive the second connecting block 13 and the brush 15 to move synchronously.
