Description

Technical Field

[0001] This invention relates to the field of environmental testing and observation technology, and in particular to a surface-level air-sea environment simulation test chamber. Background Technology

[0002] The marine climate environment, or sea-atmosphere environment for short, is characterized by "three highs and one strong": high temperature, high humidity, high salt spray, and strong solar radiation. These are significant external factors contributing to the marine atmospheric corrosion and aging of materials. In the field of equipment environmental engineering, simulated marine corrosion testing equipment is commonly used to assess or screen durable and reliable materials and products for marine environments. By simulating or intensifying the main corrosive environmental conditions of samples, such as increasing salt spray concentration and raising sea-atmosphere temperature levels, rapid corrosion and deterioration of the samples are achieved to facilitate screening or assessment.

[0003] Because these environmental conditions need to be simulated and controlled simultaneously, traditionally manufactured test chambers are typically large or even super-large, with highly complex structures. Furthermore, these enhanced air-sea environments are usually very demanding on the equipment itself. To ensure continuous and stable operation, the equipment must not be corroded or damaged by these environmental conditions before the samples are tested. Therefore, additional protective systems for the equipment's materials and structure are added, making the already large test chamber even larger and more complex.

[0004] Existing large-scale devices are primarily multi-factor integrated marine climate environment simulation accelerated test chambers. These large test chambers involve multiple systems, each with a complex unit structure. The chamber includes an irradiation system, a spray system, a ventilation control system, an air temperature regulation system, a central control and communication system, and a human-machine interface. The manufacturing cost of a single multi-factor integrated marine climate environment simulation accelerated test chamber is conservatively estimated to be over RMB 200,000. Existing smaller / desktop-level devices mainly achieve temperature, humidity, or irradiation tests, but typically, desktop-level devices do not yet simultaneously apply the four factors of temperature, humidity, light, and salinity.

[0005] Existing large-scale, multi-factor integrated marine climate environment simulation accelerated test chambers can achieve the required functions, but their construction, operation, and maintenance costs are too high, placing a significant burden on product development and testing departments. Existing small-scale reactors (similar to test chambers) have insufficient effective testing space, and cannot effectively load and control some major marine-atmospheric environmental factors such as radiation and salinity, making it difficult to meet the testing needs of most standard specimen and test plate-level samples. Therefore, developing a small-scale marine environment test chamber with the ability to load and control major marine-atmospheric environmental factors, while also providing effective testing space for most standard test plate and specimen-level products at a lower cost, is urgently needed for the development and implementation of equipment environmental engineering. In particular, the demand for miniaturized, easy-to-install, and easy-to-use desktop marine-atmospheric environment test chambers is particularly urgent, facilitating basic corrosion and aging testing research and the exploration of marine-atmospheric environmental effects on materials and components in universities and research institutes.

Therefore, they have no substantial technical significance.

In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0022] It should also be noted that in the embodiments of this application, the same reference numerals are used to denote the same component or the same part.

[0023] It should also be noted that the "desktop-level" mentioned in this application refers to an ocean-atmosphere environment simulation test chamber that can be installed, placed, and used on the experimental desktop of an ordinary laboratory. Compared with large or medium-sized ocean-atmosphere environment simulation test chambers, the desktop-level ocean-atmosphere environment simulation test chamber described in this application has simple installation conditions and occupies less space.

[0024] The purpose of this invention is to provide a desktop-level marine-atmospheric environment simulation test chamber to solve the problems existing in the prior art. Based on the miniaturization of the device, it achieves structural isolation between the outer and inner chambers, and arranges the optical, mechanical and electrical systems in the dry outer chamber and equipment room. Seawater and salt spray exist only in the closed inner chamber, achieving effective isolation and avoiding the erosion and damage of salt spray and moisture.

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1 to 11 As shown, the present invention provides a desktop-grade air-sea environment simulation test chamber, comprising: The photothermal simulation device provides simulated ambient light and temperature. The salinity simulation device provides simulated wave impact, ambient humidity, and ambient salinity.

[0027] The photothermal simulation device includes: Outer compartment 1, used to house the saline-wet simulation device, is equipped with an observation window 101. Outer compartment 1 includes an outer bulkhead 102 and an outer door 103, which is sealed when the outer door 103 is closed. Illumination device 2, used to provide illumination. Temperature control device 3, used to control the temperature.

[0028] The saline-wet simulation device includes: The inner chamber 4 is used to hold seawater and place the sample 5. The inner chamber 4 is a sealed structure with transparent walls. A wave generator is used to create simulated ocean waves within the inner chamber 4. The wave generator includes a wave-generating component 6 and a power component 7. The power receiving end of the wave-generating component 6 is connected to the power output end of the power component 7. At least the wave-generating component 6 is located within the inner chamber 4. A bracket 8 is used to fix the sample 5. The bracket 8 is located within the inner chamber 4, above the wave-generating component 6, and has water-permeable channels.

[0029] The desktop-level air-sea environment simulation test also includes: an equipment room, which is used to install the outer cabin 1, lighting device 2, temperature control device 3, and control system.

[0030] Working principle: The marine environment is formed by the coupling of seawater, salt spray, light, and temperature. The photothermal simulation device in this application includes two parts: a light source device 2 and a temperature control device 3, which are used to provide simulated light and to form a simulated temperature field, respectively. The light source device 2 can provide a spectrum with wavelengths from 1 nanometer to 760 nanometers, the same as sunlight, and has a fixed-value adjustment function. It can output ultraviolet rays with wavelengths from 10 nanometers to 400 nanometers to simulate high sunlight intensity irradiation or achieve the effect of extreme ultraviolet irradiation. The temperature control device 3 can regulate the temperature inside the outer cabin (including heating and cooling). Heat or cold is transferred along the path of "outer cabin 1 - air inside the outer cabin - inner cabin wall - interior of inner cabin 4" until the temperatures of outer cabin 1 and inner cabin 4 are consistent, thereby achieving a controllable temperature balance in inner cabin 4. The heat exchange time is calculated according to the experimental needs, or data collected in the pre-experiment can be applied to the experiment. The inner chamber 4 contains seawater and houses the sample 5. A wave generator 6 drives the seawater to create simulated ocean waves, achieving an impact effect on the sample 5. Different water levels create three zones: underwater, water-air interface, and above water, recreating a realistic immersion environment. This eliminates the need for a separate salt spray device, simplifying the equipment and reducing its size. The outer chamber 1 and inner chamber 4 are isolated, preventing damage to the optical, thermal, and electrical equipment from seawater and salt spray. The inner chamber 4 is transparent, meeting light transmission requirements. The temperature control device 3 matches the isolated structure of the outer chamber 1 and inner chamber 4; the temperature inside the inner chamber 4 is obtained by detecting the temperature inside the outer chamber 1, avoiding contact between the temperature measuring device and seawater or salt spray. The observation window 101 allows researchers to directly observe the state of the sample 5 inside the inner chamber 4. In this invention, the optical, electrical, and thermal equipment are all controlled by a control system, which can be a directly integrated processor with input and output functions or an external computer or other similar device.

[0031] In one embodiment, a plurality of heat dissipation holes 10 are provided on the outer wall of the equipment room to dissipate the heat generated by the devices inside the equipment room to the external environment, reduce the heat in the equipment room, and ensure that the devices inside the equipment room are in a temperature range where they can work normally.

[0032] In one embodiment, a radiator is provided in the equipment room to dissipate the heat generated by the devices in the equipment room to the external environment. The radiator is located in the equipment room and the heat dissipation area of ​​the radiator faces the heat dissipation hole 10.

[0033] In one embodiment, an observation window 101 is installed on the outer hatch 103. The observation window 101 includes multiple layers of insulated glass and sealing strips that seal the multiple layers of insulated glass. The light source 201 of the lighting device 2 is located inside the outer hatch 1. The insulated glass and sealing strips can effectively cut off the gas exchange between the outer hatch 1 and the external environment, thereby eliminating heat transfer caused by gas exchange. Since the light source 201 is located inside the outer hatch 1, its illumination can be directly observed from the outside, confirming whether the light source 201 is in normal working condition or emitting appropriate light.

[0034] In one embodiment, the outer hatch 103 is provided with a pivot that matches the external structure of the equipment room to realize rotational movement during the opening and closing process. A safety lock 105 is provided on the outer hatch 103 to lock the outer hatch 103. The drive end of the safety lock 105 is the outer hatch handle 104. The safety lock 105 can use an existing locking device with a handle.

[0035] In one embodiment, the outer bulkhead 102 is an insulated wall, and the heat exchanger 301 of the temperature control device 3 is disposed inside the outer bulkhead 1. Heat or cold energy is directly released inside the outer bulkhead 1, which can improve the efficiency of heating or cooling. Pipes and / or lines connected to the heat exchanger 301 need to pass through the outer bulkhead 102, and the gaps between these pipes and / or lines and the outer bulkhead 102 need to be sealed to cut off the gas exchange between the outer bulkhead 1 and the external environment.

[0036] In one embodiment, the outer bulkhead 102 includes a heat transfer zone, and the heat exchanger 301 of the temperature control device 3 is disposed outside the outer bulkhead 1 and in contact with the heat transfer zone. Heat or cold is released into the outer bulkhead 1 through the heat transfer zone. Although this slightly reduces heat transfer efficiency, it eliminates the need for pipes and / or wiring to enter the outer bulkhead 1, reducing openings on the outer bulkhead 102 and directly minimizing potential leak points. Simultaneously, the temperature control device 3 is entirely located outside the outer bulkhead 1, facilitating inspection, maintenance, and replacement.

[0037] In one embodiment, the lighting device 2 includes: a light source 201 for providing light, the light source 201 including a light-emitting element and a drive controller for adjusting the color of the light; a transmission line 202 for providing power and signals to the light source 201; and a light adjustment device 203 for sending on / off signals and adjustment signals to the light source 201, the light adjustment device 203 being disposed in an equipment room; the input terminal of the light source 201 is connected to the output terminal of the transmission line 202, and the input terminal of the transmission line 202 is connected to the output terminal of the light adjustment device 203. The drive controller is an actuator that directly changes the wavelength of the light emitted by the light-emitting element. The drive controller is controlled by the light adjustment device 203, which can send signals to start the light source 201, turn off the light source 201, and change the wavelength of the light. The light adjustment device 203 is controlled by the control system. The transmission line 202 includes a power line and a data line.

[0038] In one embodiment, the light source 201 is a variable spectrum light-emitting diode (LED) lamp.

[0039] In one embodiment, the light source 201 is a variable spectrum xenon lamp.

[0040] In one embodiment, the temperature control device 3 includes: a heat exchanger 301 for raising or lowering the temperature of the outer cabin 1; a heat exchange medium pipe 302 for supplying a heat exchange medium to the heat exchanger 301; and a compressor 303 for adjusting the temperature of the heat exchange medium and driving its flow, the compressor 303 being disposed within the equipment room. The input and output ends of the heat exchanger 301 are respectively connected to the heat exchange medium pipe 302, and the input and output ends of the compressor 303 are also respectively connected to the heat exchange medium pipe 302. The heat exchanger 301, the heat exchange medium pipe 302, and the compressor 303 form a heat exchange medium circulation loop. The heat exchange medium circulates within the heat exchange medium circulation loop, releasing cold or heat within the heat exchanger 301 and receiving heat or cold within the compressor 303. The heat exchanger 301 is preferably a plate-like structure. When contact heat exchange is used, the flat heat exchange surface enhances heat exchange efficiency through sufficient contact. When non-contact heat exchange is used, heat dissipation fins are installed on the heat exchange surface to increase the heat dissipation area and improve heat exchange efficiency. The heat exchanger 301 can be a single-cavity structure, or it can be further equipped with bent and arranged heat exchange tubes inside. The heat exchange medium can be a liquid or a gaseous medium.

[0041] In one embodiment, the heat exchange medium pipe 302 is an integrally structured insulated pipe, and the heat exchange medium pipe 302 is made of insulation material.

[0042] In one embodiment, the heat exchange medium pipe 302 includes a medium conveying pipe and an insulation structure, with the insulation structure disposed on the outside of the medium conveying pipe.

[0043] In one embodiment, a hollow sealing sleeve is fitted around the heat exchange medium pipe 302, and the air inside the sealing sleeve is evacuated to form a vacuum area, which serves as an insulation layer.

[0044] In one embodiment, the insulation layer is an insulation material layer, which can adopt an existing insulation structure.

[0045] In one embodiment, the wave generator 6 is a stirring blade, and the power unit 7 includes an electric motor. The electric motor is located outside the inner chamber 4, and its output end is connected to the first end of a drive shaft 9. The second end of the drive shaft 9 extends into the inner chamber 4 and is connected to the stirring blade. A seal is provided between the drive shaft 9 and the inner chamber 4. The stirring blade includes at least two blades with equal angular spacing. The electric motor is a type that can rotate in both forward and reverse directions.

[0046] In one embodiment, the power unit 7 is disposed within the equipment room and below the inner chamber 4, and a seal is provided between the drive shaft 9 and the outer chamber 1. The motor's placement below the inner chamber 4 allows the drive shaft 9 to be inserted into the inner chamber 4 from bottom to top, preventing the drive shaft 9 from passing through the area where the sample 5 is placed and eliminating potential interference.

[0047] In one embodiment, the inner chamber 4 includes a removable top cover 401, and the inner chamber 4 is made of quartz glass. The bracket 8 is a frame structure, with open spaces within the frame structure serving as water-permeable channels; the bracket 8 is made of ceramic. Quartz glass has good light transmittance and strong heat transfer capacity, making it suitable for this invention. The open areas of the bracket 8 serve as excellent water-permeable channels, meeting the needs of wave-impacted samples 5, partially immersed samples 5, or fully immersed samples 5. Ceramic has good salt resistance, making it suitable for use in seawater environments.
