Description

The electronic metal Rustproofing apparatus
The utility model belongs to electrochemical cathodic protection metal rust preventing technical field, relates to equipment such as the metal construction that is used for automobile, boats and ships, precision instrument, petrochemical complex, bridge construction and military installations, the Rustproofing apparatus under seawater, water and humid atmosphere environment.
When metal exposes in seawater, water and humid atmosphere environment, metal contacts with above-mentioned ionogen, and unbound electron is seized by ionogen in the metal, and burning is got rusty.For preventing that metal from getting rusty, common way is that method such as the outside surface coating, plating, enamel at metal covers layer protective layer and completely cuts off ionogen such as seawater, water and humid atmosphere and seize unbound electron in the metal, thereby prevents to get rusty.In case protective layer is impaired corrosion will take place, in addition, pollute the environment in the process of implementing the coating protective membrane.
The purpose of this utility model provides a kind of electronic metal Rustproofing apparatus that can overcome above-mentioned defective.
What the utility model adopted is cathode protection technology; it comprises current controller, anode head two portions: feature is that the output head anode of current controller is exported pulsed current to the anode head input anode, and its negative pole of output end directly is connected with protected metal device.The input termination direct current of current controller is input to the application specific integrated circuit module and exports pulse through integrated regulator, delivers to output head anode through bipolar transistor and current-limiting resistance; The anode end face of anode head is established insulation layer, and the anode head input anode is joined by printed circuit board (PCB) and anode and variable resistor input terminus, places in the seal protection layer, and variable resistor output terminal lead-in wire is connected with protected metal device.
The utility model can be protected the inaccessible place of way with metal coat, and such as zones such as hardware internal surface and recessed, seam, groove, holes, guard time is long, pollution-free, save the energy, and this installation cost is low, install simply.
