A Corrosion Test Device Capable of Alternating Water Depth

Abstract

The invention relates to a corrosion test device capable of realizing alternating water depth of sample injection, comprising a buoyancy tank, a winch system, a test frame, an automatic wire reel, a base, an acoustic release device and a ballast block; the winch system is placed in the buoyancy tank, Open the sea hole at the bottom of the buoy, the rope of the winch system passes through the sea hole and connects with one end of the test frame, and the other end of the test frame is connected with the automatic wire reel through another rope; the automatic wire reel is connected with the base The top is fixed, and the bottom of the base is connected to the ballast block through the acoustic release device. The invention has the advantages of simple structure, convenient use and easy assembly and disassembly. The invention can realize the alternate change of the water depth position of the test frame in the marine environment corrosion test through the buoy box, the winch system, the main cable, the test frame, the automatic wire reel and the concrete ballast block. The invention can be used for the corrosion aging performance research of materials and coatings under the condition of alternating water depth, and solves the problem that the current marine environment corrosion test device cannot be applied to the working condition of alternating water depth.

Description

technical field [0001] The invention relates to the field of marine environment corrosion tests, in particular to a corrosion test device capable of realizing alternating water depths for sampling, which is mainly used for research on the corrosion aging performance of materials and coatings under the conditions of alternating water depths. Background technique [0002] The ocean is rich in biological, oil and gas, and mineral resources. With the depletion of land resources, countries around the world have begun to focus on the ocean for resource development. Among them, high-performance marine engineering materials are the prerequisite for the safe and efficient development of marine resources. Seawater is a highly corrosive medium. During the design process of marine engineering equipment, if the material selection or structural design is unreasonable, corrosion problems will inevitably occur. In order to obtain the corrosion aging data of materials and coatings in the ma...
