[Prior Art]

 Since the discovery of metal by humankind, rust has traditionally been a nuisance that significantly shortens metal life. For this reason, chemicals are sprayed or applied as rust-preventive treatment, but this requires labor, time, and technology, which results in high costs and a limited life.

The generation of rust is oxidation, which is related to water and air. Furthermore, the progress of rust is promoted by soil, hydrochloric acid, dilute sulfuric acid, scientific substances, and gas, and such substances are used as electrolytes. In other words, the electrolyte contains ions and carries a direct current by the movement of the ions, so it has the property of allowing the flow of current, and the electrolyte is a substance that easily conducts electricity.

From these things, the reason why rust occurs is caused by the electrochemical reaction of electrolytes such as water, air, soil, hydrochloric acid, dilute sulfuric acid, chemical substances, and gas with metals.

The fact that rust electrochemically occurs is related to the atom, and the atom is composed of a nucleus containing a proton having positive electricity and a plurality of electrons having negative electricity. The electrons have the same number of pluses and minuses, are attracted to each other, take a balance, and exist as stable atoms.

However, since the electrons that move around the outside of the nucleus have a weak force of attracting each other, some stimuli leave the nucleus and move freely in the metal, which is called a free electron. ..

Free electrons have various functions, and electric current is one of them. When electrons move, an electric current is generated. Electrolytes such as water, air, soil, hydrochloric acid, dilute sulfuric acid, chemical substances, and gas become metal. When touched, free electrons are taken away by the electrolyte containing ions, and other electrons are also stimulated to cause a violent reaction.

This reaction is oxidation, and electrons in the electrolyte are deprived of electrons, so that the number of electrons in the metal is reduced, the metal is melted and becomes brittle, and the property is changed. ..

The generation of rust is caused by the movement of metal electrons to another substance, and the speed of progress changes depending on the nature of the substance in contact, that is, the movement of electrons is an electric current. As the current increases, the rust progresses faster.

The following can be considered in order to prevent rust from being generated on the metal. (A) Do not bond metal and electrolyte. (B) Do not let electrons in the metal escape. (C) When electrons are depleted in the electrolyte and the number of electrons in the metal decreases, the electrons are replenished. These things prevent rust from occurring and prevent it from progressing.

Regarding (a) and (b) described above, the surface of the metal is covered by painting, plating, enamel, etc. to block water and air, and to remove moisture and air itself in the air. Change the environment. Furthermore, chemicals that prevent rust are sprayed to prevent contact with the electrolyte and prevent rust.

However, even if rust-proofing treatments such as (a) and (b) are applied, the coating and plating will eventually be peeled off, and rust will occur if the surface is scratched. It is possible to prevent the rust by replenishing the electrons with respect to the consumption of the electrons.

From those things, electric rust prevention technology such as anodic rust prevention method and cathodic rust prevention method was developed and used for structures such as buildings, ships, pipelines, storage tanks, steel towers, etc. Made up of facts.

[0014]

[Problems to be solved by the device]

 The anodic rust prevention method uses the potential difference of the metal without using a power source and sticks a metal (aluminum alloy etc.) different from the rust prevention target to generate electricity and replenish electrons to prevent rust. This is to increase the effect, and at this time, one metal is consumed by depriving electrons, so it is also called a sacrificial anode method.

The cathodic rust prevention method converts electric power supplied from an electric power company (hereinafter referred to as a general power supply) into a direct current through a battery, or uses the electric power of a battery that is being charged to perform a metal operation. By directly applying an electric current to (hereinafter referred to as rust prevention target), electrons are replenished to improve the rust prevention effect.

However, both the anode rust prevention method and the cathode rust prevention method have advantages and disadvantages. With regard to the anodic rust prevention method, it does not require electricity such as a general power supply or a battery to improve the rust prevention effect, so it has the advantage of significantly lowering equipment costs and simplifying construction. Occurs.

However, the degree of wear of the metal (aluminum alloy, etc.) different from the rust-preventive object is severe, and it is necessary to replace it frequently, which causes the drawback of increasing the number of maintenances. It is difficult to use for structures such as pipelines, storage tanks, and steel towers, and is mainly used for ships and vehicles.

Regarding the cathodic rust prevention method, a battery is used or a general power supply is converted into a direct current through the battery and a current is directly applied to an object to be rust-proof, thereby replenishing electrons and improving the rust-proof effect. Therefore, the system itself is simple, and the advantage that it requires less maintenance is brought about.

A drawback of the cathodic rust prevention method is that it is a rust prevention method in which an electric current is directly applied to an object to be rust-prevented. As it is located in the coastal area and in the wilderness where general power sources are not installed, this equipment cannot be installed.

From the above, an electronic anticorrosion technology has been developed that combines an anode (a metal different from the anticorrosion target object) and a current-carrying probe wire. It became possible to eliminate some of the disadvantages.

For example, regarding the degree of consumption of a metal (aluminum alloy, etc.) different from the rust prevention target, which is a drawback of the anode rust prevention method, a metal (aluminum alloy, etc.) different from the rust prevention target is used as the anode, and the energized probe wire is used. Therefore, if a large amount of electrons are required due to contact with electrolyte such as water droplets on the property subject to rust prevention, use a battery or a large amount of current from a general power source through a battery probe wire through a battery. Since it corresponds to the supply of flow-through electrons, the degree of consumption of metals (aluminum alloys, etc.) that are different from the rust prevention target is significantly reduced.

Further, since it is frequently used for maintenance, it has not been used for structures such as buildings, pipelines, storage tanks, steel towers, etc. However, since the number of maintenance is also reduced, various costs can be reduced, and construction work can be performed. Since it can be performed easily, it has also been used for construction.

The drawback of the cathodic rust prevention method is that the overcurrent is grounded in the ground, which may affect adjacent structures. ) As an anode and a current-carrying probe wire, and except when a large amount of electrons are required because the electrolyte comes into contact with the object to be rust-proofed, a small amount of current flows due to the potential difference between the metal (aluminum alloy etc.) different from the object to be rust-proofed. Since there is no need for a large amount of current to flow because the electrons are supplied to replenish the electrons, there is no effect on the adjacent structures, and the work can be performed easily, so there are various costs. It can also be reduced.

As described above, the electronic anticorrosion technology is a technology in which the advantages of the anode anticorrosion method and the cathode anticorrosion method are incorporated, but the technology does not solve the problems related to the power supply. ..

As the power source for the electronic rust prevention method, a battery or a general power source is used, but in the case of a battery, it is necessary to prepare a charged spare battery, and it takes extra time and expense to switch or replace the battery. Is.

When using a general power source, a dedicated outside line work is required from the control building or the breaker of the building, and a converter from AC100V / 200V to DC12V is required, so the equipment cost is high. Furthermore, this facility cannot be installed in buildings constructed in coastal areas or in the wilderness where general power is not laid.

[Action]

 It is an electronic rust prevention technology that has been constructed by taking advantage of the anodic rust prevention method and the cathodic rust prevention method, which used to be carried out by using the potential difference of metal without using a power supply or by using a battery or a general power supply. However, the problems related to the power source, which were not solved by that technology, were solved by installing a solar cell.

[0029] Therefore, what kind of structures are built in coastal areas and in the wilderness, such as places where the electric power supplied by the electric power company is not installed, ships, pipelines, storage tanks, steel towers, etc. Moreover, this equipment is inexpensive and can be installed by a simple construction method.

Embodiment 1 An embodiment according to the present invention will be described with reference to FIGS. 1 and 2 showing this embodiment. The sunlight is collected by the solar cell A, converted into a direct current, and supplied to the controller B by turning on the power switch 1.

The direct current supplied to the controller B causes an oxidation reaction when the electrolyte 7 such as water droplets comes into contact with the positive electrode 7 and the object X for rust prevention in the current / electron supply section E, and Since the rusted property X requires a large amount of electrons, maximum current is passed.

As described above, the DC current supplied from the solar cell A is adjusted by the 12V converter 3 and the 5V adjuster 4 and reaches the current / electron supply unit E through the limiter D to prevent rust. Supply electrons to the target property X.

The current / electron supply unit E is composed of the humidity sensor 6 and the anode 7, and when the anode 7 and the rust-prevention target X are contacted with the electrolyte 10 such as water droplets, the maximum rust-prevention target X is reached. A current flows, but a limiter D prevents the current from flowing too much.

The humidity sensor 6 is composed of a humidity sensor and a probe wire 12. The blow wire 12 is grounded to the object X to be rust-prevented, and a command from the humidity sensor is given even when the humidity in the air is low. As a result, the minimum current is always passed through the probe wire 12 to supply electrons to the rust prevention target object X.

When a large amount of electrons are not required in the rust prevention target property X, the controller B switches to automatic charging to charge the battery C and back up when the solar cell A cannot operate at night. . The ground 8 is branched from the 12V converter 3 and grounded to the rust prevention target property X.
