Description
Technical field
The present invention relates to a kind ofly under laboratory environment, be used for the test unit of bimetallic corrosion between any two kinds of different metal materials of research soil media.
Background technology
Grounded screen is to be embedded in transformer station's soil, has the important device of lightning protection and grounding earial drainage effect, in the process of its use, for fear of because the corrosion that environmental factor causes increases the service life, usually selects corrosion stability preferably metal or alloy material.If but have potential difference between other hardwares of selected metal material and transformer station, along with the intervention of Korrosionsmedium such as air, wet part etc., being easy to the corrosion of coming in contact property in the place that other hardwares of grounded screen and transformer station contact is bimetallic corrosion so.The loss of bimetallic corrosion meeting accelerating anode material (the lower metal material of current potential in two kinds of metal materials of contact) brings hidden trouble for the safe operation of transformer station.Therefore, the bimetallic corrosion of different metal in the research soil environment, for preventing spillage of material, the long-term safety operation of optimizing material type selecting and transformer station is significant.At present, under laboratory environment, the method that galvanizing corrosion test generally adopts is: with epoxy resin that the weld sealing is fixing more first with wire and test piece welding, and the vertically opposite position and the spacing that hang Control Assay by wire.This way is when adopting weightless Calculation of corrosion speed, and epoxy resin is difficult to remove, and affect result of calculation, and the vertically opposite position between the sample and spacing only be difficult to realize accurate control by solid conductor, has increased the instability of testing.
Summary of the invention
The present invention is for avoiding the existing weak point of above-mentioned prior art, provide a kind of simple to operate, accurately the vertically opposite position between the Control Assay, easyly adjust experiment device for couple corrosion in the soil media of sample spacing according to testing requirements rapidly, in order to accurately obtain the galvanizing corrosion test result.
The present invention is that the technical solution problem adopts following technical scheme:
The design feature of experiment device for couple corrosion is to arrange in the soil media of the present invention:
One rectangular open top container is level and is fixedly installed each root support bar between the panel of described open top container and backboard, comprising: be in left side bar, intermediate bar and right-hand rod on the same level face; Be down the lower-left bar that " product " type is arranged with described left side bar and intermediate bar; Be down the bottom right bar that " product " type is arranged with described right-hand rod and intermediate bar; Described left side bar, right-hand rod, lower-left bar and bottom right bar are concave groove along the bar length direction; Wherein the left side bar the concave groove notch to the right, the concave groove notch of right-hand rod is left; The concave groove notch of lower-left bar and bottom right bar upwards; The transversal section of described intermediate bar is " worker " type, its along the bar length direction be back-to-back about two concave grooves;
In the concave groove of described each root support bar, be respectively arranged with plate, described plate along on the length direction of concave groove with scale mark, and by scale value each slot that be arranged in parallel;
Take left side bar, intermediate bar and lower-left bar as a unit, be upright test piece and be inserted on left side bar, intermediate bar and the lower-left bar centerboard in the slot on the corresponding scale value;
Take right-hand rod, intermediate bar and bottom right bar as a unit, be upright test piece and be inserted on right-hand rod, intermediate bar and the bottom right bar centerboard in the slot on the corresponding scale value.
The design feature of experiment device for couple corrosion also is in the soil media of the present invention: on described left side bar, right-hand rod, lower-left bar and bottom right bar, the trench bottom that is positioned at concave groove arranges fastening bolt, with the position of described fastening bolt fixing insertion in concave groove.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention arranges each support bar by " product " type that falls, and utilizes the effective location with graduated plate, can regulate easily and accurately reads the test piece spacing, can also accurately control the position of test piece, assurance test piece plane vertically opposite.
2, the present invention is easy and simple to handle, does not need the processes such as complicated test piece encapsulation and wire be fixing before the test, and test piece that only need to polishing is good is inserted slot and got final product; Directly extract test piece after the off-test from slot, carry out the simple surfaces processing and can calculate weight-loss corrosion speed, the test findings accuracy is high, favorable reproducibility.
3, experimental enviroment of the present invention variation is not limited to soil media, can fill other media in apparatus container according to testing requirements and realize galvanizing corrosion test under the varying environment.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is centerboard structural representation of the present invention;
Number in the figure: 11 left side bars; 12 intermediate bars; 13 right-hand rods; 14 lower-left bars; 15 bottom right bars; 3 fastening bolts; 4 plates; 41 slots; 5 open top containers; 51 panels; 52 backboards.
Embodiment
Referring to Fig. 1 and Fig. 2, in the present embodiment in the soil media structure of experiment device for couple corrosion be set to:
One rectangular open top container 5 is level and is fixedly installed each root support bar between the panel 51 of open top container 5 and backboard 52, comprising: be in left side bar 11, intermediate bar 12 and right-hand rod 13 on the same level face; Be down the lower-left bar 14 that " product " type is arranged with left side bar 11 and intermediate bar 12; Be down the bottom right bar 15 that " product " type is arranged with right-hand rod 13 and intermediate bar 12.
As shown in Figure 1, left side bar 11, right-hand rod 13, lower-left bar 14 and bottom right bar 15 are being concave groove along the bar length direction; Wherein the left side bar 11 the concave groove notch to the right, the concave groove notch of right-hand rod 13 is left; The concave groove notch of lower-left bar 14 and bottom right bar 15 upwards; The transversal section of intermediate bar 12 is " worker " type, its along the bar length direction be back-to-back about two concave grooves;
Shown in Figure 2, in the concave groove of each root support bar, be respectively arranged with plate 4, plate 4 along on the length direction of concave groove with scale mark, and by scale value each slot 41 that be arranged in parallel;
In the implementation, take left side bar 11, intermediate bar 12 and lower-left bar 14 as a unit, be upright test piece and be inserted on left side bar, intermediate bar and the lower-left bar centerboard in the slot on the corresponding scale value; Also comprise take right-hand rod 13, intermediate bar 12 and bottom right bar 15 as a unit, be upright test piece and be inserted on right-hand rod, intermediate bar and the bottom right bar centerboard in the slot on the corresponding scale value.
