Description

Technical Field

[0001] The invention relates to the technical field of artificial fish reefs, in particular to a multi-factor coupled corrosion and impact comprehensive testing device for artificial fish reefs. Background Art

[0002] As an important facility for marine ecological restoration and fishery resource proliferation, artificial reefs are exposed to complex marine environments for a long time and need to withstand multiple coupling factors such as seawater corrosion, wave impact, biological sulfuric acid penetration, and light aging. In the prior art, the durability test devices for artificial reef materials are mostly focused on the simulation of a single or a small number of environmental factors, such as: Salt spray test chamber: only simulates the corrosion of seawater salt on materials, lacks the impact of dynamic wave impact and biological sulfuric acid penetration; Mechanical shock test equipment: only evaluates the material's impact resistance, without conducting comprehensive tests in combination with the corrosive environment; Light aging chamber: only focuses on the degradation effect of ultraviolet rays on materials, ignoring the synergistic effect of seawater and mechanical stress.

[0003] The above single factor test method is difficult to truly reflect the performance degradation mechanism of artificial reefs in the actual marine environment. In addition, the existing equipment has the following problems when simulating multi-factor coupling: Low coupling degree of environmental parameters: unable to simultaneously simulate the synergistic effects of seawater corrosion, biological sulfuric acid penetration, wave impact and light aging; Insufficient control of dynamic conditions: The specimen fixing method is single, which makes it difficult to simulate the effects of different water flow directions and temperature gradients on corrosion rate; Lack of exhaust gas treatment: The emission of acidic gases (such as H2S) may pollute the laboratory environment, and there is a lack of effective safety protection design.

[0004] Therefore, there is an urgent need for a testing device that can comprehensively simulate the coupling effects of multiple ocean factors to improve the research and development efficiency of artificial reef materials and the accuracy of service life prediction.
