Description

Technical Field

[0001] The utility model relates to the technical field of sacrificial anodes, in particular to a marine sacrificial anode installation structure. Background Art

[0002] A sacrificial anode is a metal that is used as an anode in electrochemical theory. The anode (metal) is gradually consumed as the current flows out. The sacrificial anode is a commonly used cathodic protection method to prevent hull corrosion. Its main installation methods are welding and bolting.

[0003] The existing marine sacrificial anode mounting structure still has some problems during use. First, in order to facilitate subsequent disassembly and assembly, the existing sacrificial anodes are partially fixed by bolts during installation. During the operation and movement of the hull, the impact force of seawater continuously impacts the nuts, including seawater that penetrates into the gaps, making the bolts loose and its stability continuously reduced. Secondly, due to the immersion in seawater, the interior of the sacrificial anode mounting structure is also prone to corrosion, and its durability is continuously reduced, thereby reducing the overall use effect.

[0020] 1. In the utility model, a shock-absorbing spring, an extrusion protection gasket and a fixed protection assembly are arranged. When the mounting screws are impacted by seawater during use, the force is reduced by the shock-proof effect of the extrusion protection gasket on the shock-absorbing spring, and the various components in the fixed protection assembly not only play a sealing role but also reduce the force of lateral vibration on the mounting screws. This not only prevents the mounting structure from loosening, but also improves the stability of the mounting structure.

[0021] 2. In the utility model, a fixed protection component is provided. When in use, the expansion filler inside the fixed protection component can absorb the infiltrated seawater, causing it to swell and expand the adsorption extrusion rubber pad, thereby forming an extrusion force and the adsorption protection cotton sleeve to improve the sealing protection of the installation connection. This not only reduces the corrosion effect of seawater on the installation structure, but also improves the overall durability and the overall use effect. BRIEF DESCRIPTION OF THE DRAWINGS

A sealing ring 10 is embedded between the two groups of extrusion protection gaskets 9. The sealing ring 10 is mainly used to prevent seawater from penetrating into the interior of the installation groove 6 and causing damage to the shock-absorbing spring. The use of the above-mentioned components plays a role of shock absorption and protection under the impact of seawater, thereby improving the overall stability of the installation structure.

[0033] Embodiment 2:

[0034] Combination Figure 3 As shown, based on the first embodiment,

[0035] Specifically, by implementing the arrangement of the components in the internal fixed protection assembly 8, the sealing of the installation structure is enhanced, the corrosion resistance is reduced, and the durability is improved.

[0036] Combination Figure 1 and Figure 2 As shown, in the above embodiment,

[0037] Specifically, the mounting bracket 3 is welded to the bottom of the hull 1. The welding setting of the mounting bracket 3 facilitates the installation of the sacrificial anode zinc block 2 and avoids damage to the hull 1 assembly caused by the sacrificial anode zinc block 2 being directly installed on the hull 1. The sacrificial anode zinc block 2 and the top end of the mounting extension wing 4 are both in contact with 3.

[0038] The working principle and use process of the utility model are as follows: first, when in use, the hull 1 is in operation, and the impact force of seawater impacts the mounting screw 5. After being subjected to the force, the longitudinal impact force received by the mounting screw 5 is reduced through the mutual elastic shock-absorbing effect of the extrusion protection gasket 9 and the shock-absorbing spring 7 sleeved on the outside thereof. At the same time, the fixed protection component 8 is located on the outside of the mounting screw 5 and between the mounting grooves 6 opened inside the mounting extension wing 4. The internal expansion filler 803 expands after meeting water to increase the elastic extrusion force of the adsorption extrusion rubber pad 801 and reduce the vibration wear force received by the mounting screw 5 in the lateral direction. This not only prevents the loosening of the mounting mechanism, but also improves the stability of the mounting structure. Secondly, the expansion filler 803 inside the above-mentioned fixed protection component 8 is introduced through the adsorption hole 802, and after absorbing the infiltrated seawater, its expansion expands the adsorption extrusion rubber pad 801, forming an extrusion force and the adsorption protection cotton sleeve 804 to improve the sealing protection of the mounting connection. This not only reduces the corrosion effect of seawater on the mounting structure, but also improves the overall durability and the overall use effect.
