Embodiment 1

[0049] as attached Figure 1-4 As shown, the main body of the multi-zone marine environment comprehensive simulation test device is composed of a power system 1, an atmospheric environment test cabin 2, a solution environment test cabin 5, an electrical equipment cabin 6, a deionized water tank 9, and a supply tank 13 composition. A hatch 3 with an observation window 4 is arranged outside the atmospheric environment test cabin 2 . A control panel 10 is arranged outside the deionized water cabin, which is used for the preset of the test program and the indication of the running status of each component. The test program adopts a modular setting method, including the atmospheric zone test mode, high temperature and high humidity test mode, splash zone test mode, tidal range zone test mode, full immersion zone test mode and erosion corrosion test mode. A liquid level indicator window 15 is provided outside the replenishment liquid tank 13 to display the liquid level height of t...

Embodiment 2

[0053] When carrying out the atmospheric zone test, the test is set to the atmospheric zone test mode through the control panel 10, and the individual tests or combined tests of wetting, drying, ultraviolet radiation and salt spray are set. Set the cycle mode, duration and test period of each stage, and set the temperature and humidity of the atmospheric environment test chamber 2 in each stage. Set the external drive shaft speed changer 41 as a low speed.

[0054] After starting the test, the sample holder 27 is maintained at the atmospheric test height. The contact converter 20 separates the horizontal contactor 21 and combines the vertical contactor 18, the lifting motor 43 and the inner transmission shaft rotation motor 40 are in a closed state, the outer transmission shaft rotation motor 42 is turned on, and the outer transmission shaft 19 drives the sample holder 27 according to the design. Rotate at a constant speed. During the wetting stage, the heating fan 23 is tur...

Embodiment 3

[0057] When carrying out the high-temperature and high-humidity test, the test is set to the high-temperature and high-humidity test mode through the control panel 10, and the temperature and humidity of the atmospheric environment test chamber 2 and the temperature of the solution environment test chamber 5 are set.

[0058] After starting the test, the sample holder 27 is maintained at the atmospheric test height. Lifting motor 43, inner transmission shaft rotating motor 40 and outer transmission shaft rotating motor 42 are all in closed state. The communication valve 49 is opened, and the test solution is injected into the solution environment test chamber 5 from the supply liquid tank 13 . When the float level sensor 50 reaches the reference level T line, the communication valve 49 is closed. The heating tube 35 is opened, and when the temperature monitored by the solution thermometer 33 reaches the set value, the heating tube 35 is closed, thereby assisting in increasing...

Abstract

The present invention provides a multi-zone marine environment comprehensive simulation test apparatus. According to the multi-zone marine environment comprehensive simulation test apparatus, a sample frame is arranged in the main body of an environment test bin, is connected to a power system, and is driven to rotate and lift by the power system; and in the power system, the positions of a horizontal contactor and a lifting motor matched to the horizontal contactor are fixed, a vertical contactor, an inner transmission shaft gear box, an outer transmission shaft gear box, an inner transmission shaft rotation motor and an outer transmission shaft rotation motor act along with the lifting of an inner transmission shaft and an outer transmission shaft, the an inner transmission shaft gear box, the outer transmission shaft gear box, the inner transmission shaft rotation motor and the outer transmission shaft rotation motor are matched to the vertical contactor, the outer transmission shaft is connected to the sample frame, and the inner transmission shaft is connected to a coaxial reverse rotation screw propeller. According to the present invention, the rotation and the lifting of the inner transmission shaft and the outer transmission shaft are controlled by the motor matched to the inner transmission shaft and the outer transmission shaft, such that the synchronous lifting and the separated rotation are achieved, and the sample frame and the coaxial reverse rotation screw propeller are respectively driven; and by combining the atmospheric environment simulation system and the solution environment simulation system, the automatic control and simulation test of the multi-zone marine environment can be achieved while a variety of test functions are integrated, such that the rapid test and the effective evaluation of the corrosion and the aging performance of the material in the tropical marine environment can be met.

Description

technical field [0001] The invention belongs to the technical field of environmental testing and observation, and relates to an indoor simulation test of material corrosion and aging performance, as well as a monitoring and control technology for a test environment, in particular to a comprehensive simulation test device for a multi-zone marine environment. Background technique [0002] The ocean is rich in products and resources, and it is also an important channel for global economic and trade exchanges. With the continuous deepening of human development and utilization of the ocean, the failure of marine equipment and facilities has become increasingly prominent. Especially in tropical sea areas, such as the South my country Sea and the Indian Ocean, due to the harsh climate characteristics of these sea areas, such as rough winds and waves, high temperature, high humidity, high salinity, and strong solar radiation, the marine environment of equipment and facilities is res...
