[0002] Basalt fiber composite material is a new type of material that uses basalt fiber as a reinforcing material and is compounded with matrix materials such as resin or metal. Basalt is a natural volcanic rock with excellent properties such as high strength, wear resistance, and high temperature resistance, making it suitable for use as a reinforcing material. After basalt fiber is compounded with the matrix material, the material's strength, wear resistance, corrosion resistance, and high temperature resistance can be improved, while the material's density can be reduced, giving it better performance and application value.

[0003] Excellent basalt fiber composite materials used in the marine field need to have excellent corrosion resistance. In order to explore the corrosion resistance of basalt fiber composite materials used in the marine field, it is usually necessary to conduct certain simulation tests on basalt fiber composite materials to simulate the corrosion environment of seawater scouring and ultraviolet aging, and explore the corrosion resistance of basalt fiber composite materials in the marine environment.

[0023] In this embodiment, the rack 9 is also provided with a plurality of hooks 10 for hanging composite materials, so that the test samples can be hung and fixed and placed in the experimental box 4, so that the test samples are more independent and do not interfere with each other, thereby making the experimental results more accurate and reliable.

[0024] In this embodiment, the sides of the water outlet main pipe 6 and the storage rack 9 are detachably connected to the inner wall of the experimental box 4 through at least two support rods 8, so that the placement of the water outlet main pipe 6 and the storage rack 9 is more stable and more flexible and adjustable.

[0025] According to experimental needs, in order to more conveniently adjust the position of the water outlet component and the storage component, in the present embodiment, the inner wall of the experimental box 4 is evenly provided with at least one pair of longitudinal limit grooves 13 along the longitudinal direction, and the side of the limit groove is provided with a plurality of transverse limit grooves 14 along the transverse direction; a positioning block is provided on the side of the support rod 8 close to the inner wall of the experimental box 4, and the positioning block is provided in the longitudinal limit groove 13 and can be moved in the longitudinal limit groove 13 and the transverse limit groove 14; when it is necessary to adjust the position of the water outlet component and the storage component, it is only necessary to slide the positioning block at the top of the support rod 8 up and down in the longitudinal limit groove 13. When it slides to the appropriate position, it can be slid into the transverse limit groove 14 on one side to limit the positioning block, thereby fixing the support rod 8 to maintain stability and flexibility during use.

[0026] In this embodiment, the bottom of the transverse limiting groove 14 is also connected to a positioning groove 15, and the positioning block can be embedded in the positioning groove 15; in this way, the limiting effect of the positioning block can be more stable, and it will not slide easily, thereby maintaining stability during use.
