[0001] The utility model relates to the technical field of corrosion detection, in particular to a copper alloy simulation corrosion detection device special for petroleum equipment. Background Art

[0002] The worm gear reducers used in oil mining are mostly made of gray cast iron and brass materials, which wear quickly, have poor self-lubrication and consume a lot of money. In the high-salinity and high-humidity environment of seawater, copper alloy is the most corrosion-resistant material, but the different process formulas of existing copper alloy materials have very different effects. Usually, the samples with different formulas are tested in a marine environment.

[0003] Under existing conditions, a copper alloy simulation corrosion detection device for marine oil equipment disclosed in announcement number CN215066038U is used to spray and immerse the copper alloy test block through the test liquid with different salt ratios in the water tank. However, it lacks effective limiting measures for the copper alloy. In particular, in order to highly simulate the working environment of the copper alloy, it is necessary to achieve dynamic contact with acid and alkali solutions. In this process, the stability of the copper alloy cannot be guaranteed, which is not conducive to conducting comparative experiments with obvious effects. Utility Model Content

The box body 1 is provided with at least two detection chambers 3 for containing solutions of different pH values, and guide grooves 4 are symmetrically provided in the detection chamber 3. By realizing repeated contact between the copper alloy and the acid and alkaline solution in the detection chamber 3, the corrosion environment is highly simulated.

[0022] The detection cavity 3 is provided with a limit mechanism for fixing the copper alloy through the sliding sleeve in the guide groove 4. Figure 2 With attached Figure 3 , further explained, the limiting mechanism includes a lifting bracket 5 slidably mounted in the guide groove 4, and through holes 6 are symmetrically opened at both ends of the lifting bracket 5, a steering rocker 7 is rotatably installed in the through hole 6, a driving cylinder 8 is fixedly installed in the lifting bracket 5, and a first connecting rod 9 is connected between the output end of the driving cylinder 8 and the upper end of the steering rocker 7, a limiting clamp 10 movably pulled by the steering rocker 7 and used to fix and clamp the copper alloy is slidably mounted in the through hole 6, and the limiting clamp 10 symmetrically arranged on the left and right clamps and fixes the copper alloy when facing each other, thereby ensuring the stability of the copper alloy driven by the lifting bracket 5 to move up and down to contact the solution.

[0023] A driving motor 15 and a U-shaped shaft 16 driven to rotate by the driving motor 15 are provided on the load-bearing truss 2, and a traction mechanism is provided between the U-shaped shaft 16 and the limiting mechanism, the traction mechanism includes a steering sleeve 17 rotatably mounted on the U-shaped shaft 16, and a traction frame 14 is integrally connected to the lifting bracket 5, and a second connecting rod 18 is connected between the steering sleeve 17 and the traction frame 14. The U-shaped shaft 16 generates a height difference during rotation, and the lifting bracket 5 is driven to move up and down through the steering sleeve 17 and the second connecting rod 18, so that the copper alloy is repeatedly in contact with the acid and alkali solution.

[0024] The load-bearing truss 2 is disposed transversely corresponding to the detection cavity 3 in the box body 1 .

[0025] Please refer to the instruction manual for details Figure 3 The two ends of the first connecting rod 9 are respectively connected to the output end of the driving cylinder 8 and the pin shaft of the upper end of the steering rocker arm 7. A guide long hole 11 for slidingly sleeved on the lower end of the steering rocker arm 7 is opened in one end of the limiting clamp plate 10 located in the through hole 6, and a traction long hole 12 is opened in the lower end of the steering rocker arm 7. A driven long bolt 13 slidably sleeved in the traction long hole 12 is integrally connected in the guiding long hole 11. The steering rocker arm 7 applies pressure to the driven long bolt 13 through the traction long hole 12 during the deflection process. At the same time, under the limiting action of the lifting bracket 5, the limiting clamp plate 10 is horizontally extended and retracted, thereby performing a loosening and tightening operation on the copper alloy.

[0026] The driving motor 15 is fixedly installed at one side of the load-bearing truss 2 , and the U-shaped rotating shaft 16 is rotatably installed on the load-bearing truss 2 corresponding to the detection cavity 3 .

[0029] The functional principle of the utility model can be explained through the following operation modes:

[0030] Prepare at least two identical copper alloys and solutions of different pH values;

[0031] The copper alloy is placed in the lifting bracket 5, and the output end of the driving cylinder 8 is controlled to contract, and the upper end of the steering swing rod 7 is squeezed by the first connecting rod 9, so that the steering swing rod 7 deflects in the through hole 6, and the lower end of the steering swing rod 7 deflects in the guide long hole 11 of the limit clamping plate 10, and the limit clamping plate 10 is driven to extend horizontally out of the through hole 6 through the traction long hole 12 and the driven long bolt 13, so as to clamp and fix the copper alloy;

The U-shaped shaft 16 pulls the traction frame 14 through the steering sleeve 17 and the second connecting rod 18, so that the lifting bracket 5 performs a reciprocating lifting motion along the guide groove 4, thereby achieving repeated contact between the copper alloy and the solution.
