Description
Technical Field
The utility model relates to a steel sluice gate cathodic protection technical field especially relates to a steel sluice gate cathodic protection potential automatic acquisition and monitored control system.
Background
The steel structure water gate is an important component for controlling water level in hydraulic buildings such as hydropower stations, reservoirs, water gates, ship locks and the like. The steel gate is immersed under water for a long time, frequent dry-wet alternation is realized during opening and closing, the steel gate is washed by high-speed water flow, particularly the water line part is affected by water, sunlight and aquatic organisms, and is also washed by water waves, tidal surges, silt, ice and other floating objects, steel is easy to corrode, the bearing capacity of the steel gate is obviously reduced, and the safety of hydraulic engineering is seriously influenced. The corrosion not only affects the safe operation of the sluice gate structure, but also consumes a large amount of manpower, material resources and financial resources to carry out anti-corrosion work, according to statistics of some sluice gate projects, the annual expenditure for gate corrosion prevention accounts for half of the annual maintenance cost, and a large amount of labor force is also required to remove rust, paint or spray and the like. Therefore, in order to effectively control the corrosion of steel, prolong the service life of the steel gate and ensure the integrity and safety of hydraulic and hydroelectric engineering, the long-acting corrosion prevention problem of the steel gate has attracted people's extensive attention. The steel structure water gate is commonly used in an anticorrosion method, and most of the engineering uses the anticorrosion of a covering layer and the electrochemical protection. The corrosion prevention principle of the two coatings is different from each other, the coating mainly isolates a corrosion medium from a steel gate, and the metal coating (commonly used as a zinc coating and an aluminum coating) utilizes the principle of electrochemical protection. The coating used for the coating is organic matter, the service life is generally within 10 years, and with the continuous improvement of the electrochemical protection technology in recent years, the electrochemical protection method which is one of the gate protection methods is gradually applied to the corrosion prevention technology of the gate and gradually plays a greater and greater role. Although the service life of the metal coating is prolonged, manpower and material resources are wasted, and zinc mist generated in the spraying process of the metal coating not only pollutes the environment, but also is extremely unfavorable for the body of an operator, so that a cathode protection technology is derived.
Cathodic protection is an anti-corrosion measure that maintains the protected equipment at a negative potential to ground in order to prevent corrosion of communication lines or equipment. The principle of cathodic protection is that a negative potential is considered to be connected to the metal sheath of the cable, and a positive electrode is connected to an electrode away from a certain distance, so that the metal sheath of the cable has a negative potential to the ground. The cathodic protection is used in many occasions, the voltage of the cathodic protection is adjustable and is generally composed of a power transformer and a bridge rectifier, the used power load is large, an alternating current 220V power supply is converted into direct current through the transformer and a rectifying circuit, a negative electrode is connected to a metal sheath, and a positive electrode is grounded, so that the cable sheath is ensured to keep a proper negative potential to the ground.
There are generally two types of cathodic protection: impressed current cathodic protection and sacrificial anode cathodic protection. The cathodic protection of the sacrificial anode is to connect the metal with more negative potential with the protected metal and to make the electrons on the metal transfer to the protected metal in the same electrolyte, so that the whole protected metal is at the same more negative potential. The method is simple and easy to implement, does not need an external power supply, rarely generates corrosion interference, and is widely applied to protecting small metal structures such as urban pipe networks, water gates and small storage tanks.
In the prior art, there is an example of applying cathodic protection technology to a steel sluice gate, such as a patent document "201020125214.9" entitled "a cathodic protection system for a steel sluice gate, which discloses a specific way of cathodic protection, but does not consider the environmental factors of the steel sluice gate: at present, due to the fact that geographical positions of a plurality of domestic dams are different, upstream and downstream water quality is different, environments where steel sluice gates are located are different, if upstream and downstream water levels are different, water quality is different (electrolytic environments in cathode protection are caused), if fresh water rivers are arranged on the upstream of the sluice gates, seawater areas are arranged on the downstream of the sluice gates, the water level can be changed frequently under the tidal action of seawater, only a cathode protection mode in the prior art is adopted, the steel sluice gates cannot be protected in place, and corrosion in different degrees occurs in different places.
The cathodic protection method is used as a professional metal protection method, in the traditional field, data acquisition needs to be carried out manually, data of different protection points at different time are recorded one by one, the data acquisition and statistics process is very troublesome, time and labor are wasted, and timely monitoring is difficult to achieve, so that the result of improper protection is often caused because an anode block which loses effect cannot be searched timely. Meanwhile, due to the impact force of seawater flood tide, the anode block is easy to knock and fall off, so that the protection effect cannot be achieved, but cannot be found in time.
