Background

The sacrificial anode technology is widely applied to the corrosion protection industry and is an effective metal corrosion prevention method. The basic principle of the method is that metal with strong reducibility is used as a protective electrode and is connected with protected metal through a conductive medium to form a primary battery. In the formed primary battery, the metal with stronger reducibility is used as the anode of the primary battery to generate oxidation reaction, and is gradually consumed along with the outflow of electrons, so that the protected metal is used as the cathode of the primary battery to avoid corrosion.

At present, the sacrificial anode used on the ship body needs to consider reducing the ship resistance, so the sacrificial anode with the plate structure as far as possible is flatly attached to the surface of the ship bottom shell, and the surface amplification of the simulated state is even far smaller than that of shellfish attached to the ship bottom, so that the amplification of the ship body resistance on the water bottom is eliminated. However, due to the requirement of flat attachment, the attachment components used are quite limited, and for the hull maintenance industry, it is also necessary to compromise the difficulty and efficiency of the construction work.

Detailed Description

The following detailed description is made of specific embodiments of the present invention with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and grasp, and thus make a clearer definition of the protection scope of the present invention.

In view of the installation condition that the sacrificial anode of plate structure was flatly pasted in hull bottom outer wall is severe, for the requirement to the hull flatly pasting sacrificial anode product operating speed, the utility model discloses the designer summarizes oneself and pursues the experience of this trade for a long time and innovates research and development, and the interior appearance characteristic of sacrificial anode is optimized in the improvement, has provided a hull flatly pastes formula sacrificial anode to promote yacht maintenance efficiency.

The summary scheme of the innovation is that the ship hull flat-attached sacrificial anode has a flat bottom surface, the surface except the bottom surface is a three-dimensional cambered surface, and as the characteristic of optimal design, the sacrificial anode is provided with more than one through hole vertical to the bottom surface, only one through hole is embedded with a nut, and the nut is screwed and positioned on a bolt inverted to the ship hull, so that the sacrificial anode product is firmly attached to the ship hull. The principle and effect of the design are explained as follows, firstly, the flat bottom surface is the basic condition for realizing flat adhesion of the ship body, secondly, the bolt inverted by the ship body is a prefabricated part, and the ship body and the bolt are integrated into a whole structure by adopting the processing technologies of welding, riveting and the like; only one through hole is embedded with a nut, so that the sacrificial anode can be sleeved on the screw in a threaded manner and is continuously close to the ship body when being installed; finally, the sacrificial anode is also free of other fastening structures other than nuts, and is further positioned to prevent rotation of the sacrificial anode in the contact plane, as will be described in more detail in the following embodiments.
