A device for testing the corrosion rate of buried pipeline under the condition of earth direct current backflow

Abstract

The application discloses a buried pipeline corrosion rate testing device under the condition of earth DC backflow, and belongs to the technical field of corrosion testing, which comprises a box body, a testing mechanism main body is connected to the outside of the box body through a cable, a valve plate mechanism is fixedly installed on one side of the box body, a mixing mechanism is fixedly installed on the other side of the box body, and a bottom plate is fixedly installed on the bottom of the box body through a discharging inclined mechanism. In the application, the soil overflowing from the end of the mixing auger can be reset to the front side of the box body under the action of gravity, so that the material can be fully mixed and treated, the lifting cylinder is elongated to push the top hinged block and the first rotating block to move upwards, the first rotating block can pull the sliding sleeve to slide outside the sliding rod, at this time, the box body can be tilted, the valve plate main body is separated from the box body by cooperating with the work elongation of the electric push rod, at this time, the soil can be quickly discharged, and the material removal efficiency after testing is improved.
