[0002] The problem of material corrosion failure is one of the main factors leading to the service failure and shortened life of engineering facilities and equipment. A systematic study of the corrosion behavior and long-term evolution law of materials is a necessary basis for establishing the reliability evaluation and durability design of engineering structures, as well as developing corrosion-resistant, long-life, and high-performance engineering materials. At present, the corrosion data monitoring generally adopts the method of long-term coupon hanging. And the long-term coupon hanging experiment needs to be carried out on an atmospheric corrosion exposure test bench rack. The currently commonly used atmospheric corrosion exposure test bench racks are relatively heavy and not easy to transport; their structures are complex and not easy to install and disassemble; most of the materials are Q235, which is easy to corrode, or are aluminum alloy and titanium alloy, with high prices and costs. Especially in harsh areas such as plateaus, the field construction conditions are inconvenient, and an atmospheric corrosion exposure test bench rack that can be quickly installed, has a relatively strong overall quality, and has good corrosion resistance is needed.

[0003] In the prior art, a Chinese patent with the authorization announcement number of CN 217212175 U discloses "a coupon hanging device for atmospheric corrosion exposure test", which includes an angle steel frame and a specimen mounting frame.

The specimen mounting frame includes a frame, a support panel, a slide bar, a first screw rod, a second screw rod, a first clamping plate, and a second clamping plate. A plurality of support panels are provided and are all installed on the top of the frame along the width direction of the frame. In this coupon hanging device for atmospheric corrosion exposure test, by respectively arranging a first clamping plate and a second clamping plate on the left and right sides of a plurality of support panels, a plurality of first clamping plates cooperate with a plurality of second clamping plates under the action of the second screw rod and the first screw rod to batch clamp and fix the sheet specimens located on a plurality of support panels.
