Abstract
The utility model relates to a composite groove type sacrificial anode which comprises a sacrificial anode substrate and a steel plate iron core. The middle of the steel plate iron core is fixedly installed in the middle of the sacrificial anode substrate which is rectangular. The combined groove type sacrificial anode is characterized in that the steel plate iron core is made of U-steel, and the welding ends of the two sides of the steel plate iron core are manufactured into right-angle bevel shapes. According to the sacrificial anode, the steel plate iron core is made of the U-steel, the stability of fixed installation in a sacrificial anode body is achieved, the welding area of the sacrificial anode and a building can also be increased, and the firmness is strengthened.
Description
Technical field
The utility model belongs to galvanic protection field, relates to sacrificial anode, especially a kind of compound slot type sacrificial anode.
Background technology
Various structures in oceanographic engineering, due to the erosion of seawater, need to do rotproofing.At present, the rotproofing of marine structure conventionally adopts galvanic protection or jointly carries out with paint spraying.Especially galvanic protection, applies very extensively, can carry out hardware, concrete member and various device anticorrosionly, and the especially galvanic protection of sacrificial anode, is the simplest, most convenient, the safest, the most effective anti-corrosion method.
Current sacrificial anode, is made up of steel plate iron core and sacrificial anode body conventionally, and the middle part of steel plate iron core is laterally packed in the middle part of sacrificial anode body, and the steel plate iron core that sacrificial anode body is exposed is packed in structures for welding.There are the following problems for the sacrificial anode of this structure formation:
1, the conventional cross section of sacrificial anode is rectangle or trapezoidal; the anode surface area in this cross section changes minimum at surface-area of different galvanic protection stage (initial current density, mid-term current density and latter stage current density); can not provide electric current according to the requirement of the current density of different steps, the larger electric current of Accelerated polarization particularly can not be provided effectively at the galvanic protection initial stage.
2, the steel plate iron core of sacrificial anode is generally steel band, and under seawater fluctuation, steel band is easily from weld fracture, and steel band also easily fractures at the link position of sacrificial anode.
By retrieval, not yet find the open source literature relevant to the utility model application.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of compound slot type sacrificial anode that position is reliable, primary current density is high, surface-area is larger that is welded and fixed is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of compound slot type sacrificial anode, comprise sacrificial anode matrix, steel plate iron core, the middle part of steel plate iron core is packed in the middle part of sacrificial anode matrix, sacrificial anode matrix be shaped as rectangle, it is characterized in that: described steel plate iron core adopts channel-section steel to make, and the welding end of its both sides is made right-angle folding dihedral formula.
And four jiaos, the top of described rectangular sacrificial anode substrate is shaped with chamfering, the bottom one of sacrificial anode matrix is shaped with a surrounding train of dress, also makes chamfering for four jiaos of this surrounding train of dress.
Advantage of the present utility model and positively effect are:
1, this sacrificial anode be shaped as round rectangle, can effectively reduce the swing of seawater to sacrificial anode, improved the stability that sacrificial anode is installed; Lower substrate position at sacrificial anode body is shaped with train of dress, has increased the changing value of surface-area, has correspondingly improved primary current density.
2, the steel plate iron core of this sacrificial anode adopts channel-section steel, has not only realized the stability being fixedly mounted with in sacrificial anode body, and the while also can be improved the bonding area with structures, strengthens stability.

Fig. 1 is structural front view of the present utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described; The present embodiment is descriptive, is not determinate, can not limit thus protection domain of the present utility model.
A kind of compound slot type sacrificial anode, comprises sacrificial anode matrix 2, steel plate iron core 1, and the middle part of steel plate iron core is packed in the middle part of sacrificial anode matrix, sacrificial anode matrix be shaped as rectangle.
Innovative point of the present utility model is:
1, four jiaos, the top of described rectangular sacrificial anode substrate is shaped with chamfering, and four jiaos, top is fillet form; The bottom one of sacrificial anode matrix is shaped with a surrounding train of dress 3, also makes chamfering for four jiaos of this surrounding train of dress.
2, described steel plate iron core adopts channel-section steel to make, and the welding end of its both sides is made right-angle folding dihedral formula.
