[0020] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0021] Embodiment One:

[0022] Please refer to Figures 1-4The utility model provides a technical scheme: underwater communication wireless optical signal receiving device, include: casing 1, the inside of casing 1 is provided with light receiving module and light emitting module respectively, the upper end of casing 1 is provided with top cover, and top cover is provided with optical lens, the surface of casing 1 is provided with reinforcing layer 2, the surface of reinforcing layer 2 is provided with antioxidant layer 3, the surface of antioxidant layer 3 is provided with wear -resistant layer 4.

[0023] In the embodiment, the carbon steel layer 21 is arranged, wherein the carbon steel is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%, also known as carbon steel, and generally contains a small amount of silicon, manganese, sulfur and phosphorus. Generally, the higher the carbon content in the carbon steel, the greater the hardness and the higher the strength. The chromium steel layer 32 is arranged, wherein the chromium steel refers to alloy steel containing chromium. Chromium can increase the hardenability of steel, improve the strength and wear resistance of steel, but chromium steel also has the tendency of overheating and the tendency of producing temper brittleness. Chromium steel is prone to white spots after forging. Low-carbon chromium steel has a high carbon concentration on the surface after carburizing and is brittle. It is a good carburizing steel. Chromium can increase the hardenability of steel, reduce the deformation during quenching, and is beneficial to improving the strength of the core of the carburized part without reducing the impact toughness. The steel has high cold deformation plasticity and good weldability. The cutting machinability is best in the annealed state.

[0025] Please refer to Figures 1-4 On the basis of example one, the utility model provides a technical scheme: the reinforcing layer 2 includes carbon steel layer 21, the surface of carbon steel layer 21 is provided with silicon steel layer 22, the thickness of silicon steel layer 22 is same with the thickness of carbon steel layer 21, the antioxidant layer 3 includes nickel steel layer 31, the surface of nickel steel layer 31 is provided with chromium steel layer 32, the thickness of chromium steel layer 32 is same with the thickness of nickel steel layer 31, the wear -resistant layer 4 includes manganese steel layer 41, the surface of manganese steel layer 41 is provided with aluminum lithium alloy layer 42, the thickness of aluminum lithium alloy layer 42 is same with the thickness of manganese steel layer 41, the thickness of reinforcing layer 2 is greater than the thickness of antioxidant layer 3 and the thickness of wear -resistant layer 4.

[0026] In the embodiment: through the setting of manganese steel layer 41, wherein manganese steel, alias manganese alloy steel, is a kind of high-strength steel, mainly used in harsh working conditions needing to bear impact, extrusion, material abrasion, etc., the main failure mode is abrasion consumption, partial fracture and deformation, through the setting of aluminum lithium alloy layer 42, wherein aluminum lithium alloy has excellent properties such as low density, high strength, high rigidity, high specific strength and high specific modulus. These characteristics enable aluminum lithium alloy to maintain excellent mechanical properties while reducing structural weight. In addition, aluminum lithium alloy also has good weldability, fatigue crack propagation resistance and corrosion resistance, which makes it stand out in the field of materials.

[0027] The working principle of the underwater communication wireless optical signal receiving device provided by the utility model is as follows:

[0028] The first innovative point implementation step is:

[0029] The first step is to set the carbon steel layer 21, wherein the carbon steel is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%, also known as carbon steel, and generally contains a small amount of silicon, manganese, sulfur, and phosphorus. Generally, the higher the carbon content in carbon steel, the greater the hardness and the higher the strength.

[0030] The second step is to set the chromium steel layer 32, wherein the chromium steel refers to alloy steel containing chromium. Chromium can increase the hardenability of steel, improve the strength and wear resistance of steel, but chromium steel also has a tendency to overheat and produce temper brittleness. Chromium steel is prone to white spots after forging, and low-carbon chromium steel has a high carbon concentration on the surface after carburizing, which is brittle. Chromium-containing steel is a good carburizing steel that can increase the hardenability of steel, reduce deformation during quenching, and improve the strength of the core of the carburized part without reducing impact toughness. The steel has high cold deformation plasticity and good weldability. The cutting machinability is best in the annealed state.

[0031] The second innovative point implementation step is:

[0032] The first step is to set the manganese steel layer 41, wherein the manganese steel, also known as manganese alloy steel, is a high-strength steel material mainly used in harsh working conditions that require impact, extrusion, and material wear. The failure mode is mainly wear and tear, with some cracking and deformation.

[0033] The second step is to set the aluminum-lithium alloy layer 42, wherein the aluminum-lithium alloy has excellent properties such as low density, high strength, high stiffness, high specific strength, and high specific modulus. These characteristics allow the aluminum-lithium alloy to reduce the weight of the structure while maintaining excellent mechanical properties. In addition, the aluminum-lithium alloy also has good weldability, fatigue crack propagation resistance, and corrosion resistance, which makes it stand out in the material field.
