FIG. 2 is a schematic cross-sectional view of one embodiment of the sacrificial anode shown in FIG. 1.

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.

As shown in fig. 1 and 2, the sacrificial anode 1 for a harbor dock is a strip-shaped block body with an iron core 2 built therein, and both ends of the iron core 2 exposed to the strip-shaped block body are provided as attachment portions 21 of a docking bank. As the utility model discloses to the innovative design of sacrificial anode product, be equipped with wire netting 3 more than the one deck based on 2 meet of iron core in this sacrificial anode 1, outer wire netting 3b connects to iron core 2 mutually from outside to inside successive layer through connecting rod 4 with the sacrificial anode is homogeneous, and each

layer wire netting

3a, 3b are on a parallel with the outer wall of sacrificial anode 1 and establish. It can be seen that no matter the iron core, the wire netting or the connecting rod are integrally formed and coated in the sacrificial anode body, and the states of synchronous consumption, hanging off or flow stagnation are only distinguished along with the consumption of the sacrificial anode body.

From the innovative production process of the sacrificial anode, because the sacrificial anode is formed by adopting a horizontal mold through injection molding, an iron core and a wire mesh need to be arranged before injection molding, and the relatively thin wire mesh is easy to collapse due to the lack of plane ductility strength or high-temperature collapse deformation during injection molding. The wire 3 is therefore also provided with support rods (not shown) for maintaining the planar extensibility, stabilizing the wire arranged.

The more detailed implementation structure shows that a plurality of connecting rods are arranged between every two layers of wire netting or between the innermost layer of wire netting and the iron core, and the connecting rods are distributed along the length direction of the sacrificial anode and matched with the supporting rods to form a three-dimensional support of the wire netting in the sacrificial anode material injection front mold cavity. The space distribution density and the space of the connecting rods are not limited, and the connecting rods can be distributed at equal intervals or distributed from the middle part of the sacrificial anode to the two end parts from small to large.

The section of the sacrificial anode 1 perpendicular to the length direction is square or trapezoid, as shown in the trapezoid embodiment of fig. 2, the outer wall surface of the sacrificial anode is segmented to correspond to each side of the section, and the outer wall surface of the sacrificial anode parallel to each segment is in block integration or continuous integration.

The advantages of the above innovative modified sacrificial anode embodiment are understood from the application process of the above embodiment: when the sacrificial anode product is installed in port, the cathode protection of the embankment can be realized. Along with the continuous consumption of the surface of the sacrificial anode, corrosion products attached to the outermost layer of wire netting are firstly loosened, the connection with the inner layer of wire netting and the sacrificial anode body is thoroughly disconnected along with the continuous consumption of the connecting rod, even if the consumption of the outer side surface of the sacrificial anode is locally dispersed or uneven at the moment, the outermost layer of wire netting drives the sacrificial anode at the consumption lag position to be consumed at an accelerated speed, and drives all corrosion products to be removed together, and the exposed surface of the sacrificial anode is as clean as a new sacrificial anode. In the same way, the multi-layer wire netting is periodically removed, thereby keeping the sacrificial anode to realize the function per se by high utilization rate and high performance layer by layer.

In addition, in view of the prolonged service life and maintenance period, the volume and weight of the sacrificial anode used in the port and pier are considerable, and therefore the installation strength is an important problem which cannot be ignored. In the illustrated embodiment, the mounting part is provided with a strong curved arm which is formed by continuously bending towards three directions and extends outwards, so that the sacrificial anode can be supported in all directions after being fixed by concrete pouring or bracket welding, and the sacrificial anode can reliably resist the impact of waves from the shore-going ship belt and is kept stable.

In conclusion, the sacrificial anode of the present invention is described in detail with reference to the illustrated embodiments, and it is understood that the sacrificial anode has substantial features and improvements: the sacrificial anode can be separated layer by layer along with the iron wire net along with the consumption of the connecting rod, so that the smoothness and the utilization rate of the surface of the sacrificial anode are improved, the product can fully exert the protection capability on the cathode of a port and a wharf, and a necessary foundation is provided for the large-scale recovery of protection waste materials.
