Description

Technical Field

[0001] The utility model relates to the technical field of cathode protection of steel gates, in particular to a device for measuring cathode protection potential of steel gates. Background Art

[0002] Hydraulic steel gates are important components for controlling water levels in hydraulic structures such as hydropower stations, reservoirs, sluices, and ship locks. They are submerged in water for a long time, and are frequently wet and dry when opened and closed. In particular, the waterline is affected by water, sunlight, and aquatic organisms, as well as waves, silt, ice, and other floating objects. The steel is easily corroded, which reduces the bearing capacity of the hydraulic steel gates and seriously affects the safety of water conservancy projects. Therefore, in order to effectively control the corrosion of steel, extend the service life of hydraulic steel gates, and ensure the integrity and safety of water conservancy and hydropower projects, the long-term anti-corrosion of hydraulic steel gates has attracted widespread attention.

[0003] Sacrificial anode cathodic protection is one of the commonly used anti-corrosion methods for hydraulic steel gates. It connects a metal with a more negative potential to the protected metal (i.e., the hydraulic steel gate) and places them both in the same electrolyte (i.e., the water area where the hydraulic steel gate is located). This transfers electrons from the metal with a more negative potential to the protected metal, thereby ensuring that the protected metal is at the same relatively negative potential. This method is simple and easy to use, does not require an external power supply, and rarely produces corrosion interference.

[0004] In order to detect the cathodic protection effect of hydraulic steel gates, the cathodic protection potential of hydraulic steel gates is generally measured by reference electrodes to determine whether the hydraulic steel gates have been effectively cathodically protected. During the measurement process, the reference electrodes are generally placed on the bottom of the water, in the water, and on the water surface for measurement to measure the cathodic protection potential at different depths. However, the changes in the position of the reference electrodes are all felt by the operator by hand, which has poor accuracy and is time-consuming and labor-intensive. Utility Model Content

[0047] Working principle of this embodiment:

[0048] First, the potential measuring and collecting instrument 2 is connected to the steel gate 1 and the reference electrode 3 through the wire 21;

[0049] Then, the reference electrode 3 is placed between the two clamping blocks 6, and the handle 442 is driven to rotate, and the threaded rod 441 is driven to rotate, so that the symmetrically arranged clamping driving blocks 61 move toward each other, thereby completing the clamping of the reference electrode 3 by the clamping blocks 6, and the clamping pad 63 is tightly fitted with the reference electrode 3 to prevent the reference electrode from sliding with the clamping groove 62;

[0051] Through the acoustic wave transmitter 421 and the acoustic wave receiver 422, the distance from the bottom of the water is detected as the water depth. The controller 5 controls the water inlet flow valve to open, so that water enters the ballast water chamber from the water inlet 411 until the gravity of the snorkeling shell 4 and the reference electrode 3 is greater than the buoyancy. The water inlet flow valve is closed to allow the snorkeling shell 4 to drive the reference electrode 3 to sink until the distance from the bottom of the water detected by the acoustic wave transmitter 421 and the acoustic wave receiver 422 is half of the water depth. The controller controls the water outlet flow valve and the water pump to open, so that water is discharged from the water outlet 413 until the gravity of the snorkeling shell 4 and the reference electrode 3 is equal to the buoyancy. The water pump and the water outlet flow valve are closed, and after the reference electrode 3 is stable, the data of the potential measurement collector 2 is recorded;
