Embodiment 1

[0021] The whole body of this protective device can be divided into 9 parts, including: 1. Bulkhead or tank top, the substrate to be protected in the ballast water tank, which is difficult to protect when the tank is under dry conditions. 2. Water-absorbing or moisturizing material, water-absorbing silica gel can be used in absorbent cotton, which has high water absorption and water retention, and can provide electrolyte solution for the mesh sacrificial anode protection device at any time. 3. Powerful magnets, which can generate magnetic fields and have the characteristics of attracting ferromagnetic substances, are strongly attracted to the ship's substrate, allowing sacrificial anode brackets and water-absorbing materials to be fixed at any position in the ballast water tank. 4. The watertight structure realizes the waterproof electrical connection between any two sets of mesh sacrificial anode bodies. 5. The protective potential test meter has a built-in dry battery, which...

Abstract

The invention discloses a protective device for quickly mounting a sacrificial anode for a ballast tank and an application method thereof. A water absorption and moisture retention material in the protective device can absorb electrolyte solution water, when the cabin wall (or cabin top) of the ballast tank is in air, an ion channel is provided for the aluminum-based sacrificial anode and the cabin wall or cabin top, four prongs of an iron network can pierce a coating on the surface of the cabin wall or cabin top, and an electron channel is provided for the aluminum-based sacrificial anode andthe cabin wall, so that in the gas-phase environment, an electrochemical loop is formed between a protected body cathode (cabin wall or cabin top) and the sacrificial anode (aluminum base), the sacrificial anode is consumed, electrons are released to a protected body, and therefore a cabin body is effectively protected. The protective device for quickly mounting the sacrificial anode for the ballast tank comprises the protected cabin body, the water absorption and moisture retention material, a strong magnet, a water-tight joint, a protection potential test meter head, a micro reference electrode, a cathode loop connection point, a sacrificial anode support and tip supporting legs.

Description

technical field [0001] The invention relates to a protective device for a ballast water tank, in particular to a protective device for rapidly installing a sacrificial anode in a ballast water tank and a method for using the same. Background technique [0002] The ship's ballast tank is used to provide stability for the ship and adjust the draft of the ship to meet the requirements of good maneuverability of the ship. The ballast tank is always in the state of empty tank / sea water ballast according to the needs of loading and unloading cargo during the voyage of the ship and the different sea conditions. Ballast water tanks are commonly protected by coatings and sacrificial anodes. However, since the cabin is always in a dry-wet state, when the empty bulkhead of the ship is exposed to the air, the sacrificial anode protection technology cannot achieve protection due to the lack of seawater electrolyte, resulting in The bulkheads are severely corroded. [0003] Corrosion an...
