[0029] The following description sets forth many specific details to facilitate a thorough understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific implementations disclosed below.
[0030] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0032] like Figure 1 As shown, a tropical coastal corrosion environment simulation test device includes: an experimental rack 1, an experimental box 4 and a main control box 2; the experimental box 4 is arranged in the experimental rack 1, and the main control box 2 is arranged outside the experimental rack 1. The experimental rack 1 is provided with a temperature regulating device, and the temperature regulating device is electrically connected to the main control box 2 to adjust and detect the temperature of the experimental rack 1. The experimental box 4 is arranged in the experimental rack 1, and the experimental rack 1 can form a sealed test environment. The experimental box 4 is provided with a humidity regulating device, and the humidity regulating device is electrically connected to the main control box 2 to adjust and detect the humidity in the experimental box 4.
[0033] In this embodiment, the environmental simulation test device adjusts the temperature, humidity, and salt spray concentration of the sealed environment within the test frame 1 via a temperature control device and a humidity control device disposed on the test frame 1, thereby enabling the device to simulate a tropical coastal environment in multiple aspects. Furthermore, both the temperature control device and the humidity control device are electrically connected to a main control box 2 disposed outside the test frame 1. The main control box 2 monitors and adjusts the temperature, humidity, and salt spray concentration in the sealed environment within the test frame 1. Positioning the main control box 2 outside the high-temperature, high-humidity, and high-salt spray environment further prevents the electrical control structure from being easily corroded and damaged in harsh environments, effectively protecting the electrical control structure of the environmental simulation test device and extending its service life.
[0034] See also Figure 1 and Figure 2The temperature control device includes a silicone heating wire 10 and a temperature probe 8; the silicone heating wire 10 is wound around the experimental frame 1 and electrically connected to the main control box 2. The temperature probe 8 is set in the experimental frame 1 and electrically connected to the main control box 2. The humidity control device includes an ultrasonic atomizer 7 and a humidity probe 9; the ultrasonic atomizer 7 is set in the experimental box 4 and electrically connected to the main control box 2 via a transformer 6. The humidity probe 9 is set on the experimental frame 1 and electrically connected to the main control box 2.
[0035] In this embodiment, the silicone heating wire 10 is wound around the experimental frame 1 so that the environmental simulation test device can adjust the temperature inside the experimental frame 1 in a timely manner according to the temperature monitored by the temperature probe 8. In addition, the silicone heating wire 10 is wound around the experimental frame 1 so that the contact area between the experimental frame 1 and the silicone heating wire 10 is larger, and the experimental frame 1 heats up faster. The environmental simulation test device sets the ultrasonic atomizer 7 in the experimental box 4. The experimental box 4 can be filled with salt water of different concentrations according to different environmental simulation requirements. The ultrasonic atomizer 7 generates water mist with different salt contents in the experimental frame 1 through the action of the ultrasonic atomizer 7, thereby adjusting the humidity and salt mist concentration in the experimental frame 1. In addition, the solution added to the experimental box 4 can be recycled repeatedly if it is not completely used, thereby avoiding waste of test materials.
[0036] It should be further explained that the working principle of the ultrasonic atomizer 7 is based on electronic high-frequency oscillation. The oscillation signal from the main circuit board is amplified by a high-power transistor and then transmitted to the ultrasonic chip. The ultrasonic chip converts electrical energy into ultrasonic energy. These ultrasonic energies can atomize water-soluble drugs into tiny mist particles of 1um to 5um at room temperature. When the ultrasonic atomizer 7 sprays out mist particles, it can adjust the humidity and salt mist concentration in the experimental device.
[0037] Furthermore, the temperature probe 8 and the humidity probe 9 are both placed close to the angle steel on the experimental rack 1 , so that the temperature probe 8 and the humidity probe 9 can accurately monitor the temperature and humidity in the experimental rack 1 .
[0038] like Figure 3 and Figure 4 As shown, the main control box 2 includes a temperature controller 5 and a humidity controller 12. The temperature controller 5 is electrically connected to the silicone heating wire 10 and the temperature probe 8, while the humidity controller 12 is electrically connected to the ultrasonic atomizer 7 and the humidity probe 9. The experimental rack 1 includes a heat-insulating and moisture-retaining film 13 and a bracket. The bracket comprises a plurality of interconnected and fixed angle steels. The heat-insulating and moisture-retaining film 13 is mounted on the bracket to insulate the experimental rack 1. Insulating sleeves are installed on the cables connecting the humidity and temperature control devices to the main control box 2.
[0039] In this embodiment, the bracket arrangement facilitates both the placement of test materials and the assembly, disassembly, and maintenance of the test stand 1. Furthermore, the heat-insulating and moisture-retaining film 13 wrapped around the bracket seals the test environment within the test stand 1, preventing inaccurate environmental simulation. Furthermore, the insulating sleeves provided on the connecting wires between the humidity control device, the temperature control device, and the main control box 2 further protect the connecting wires within the test stand 1 from damage caused by high temperature, high humidity, and high salt spray environments, thereby ensuring the service life and safety of the environmental simulation test device.
[0040] In a preferred embodiment, the bracket further includes a triangular connecting piece 3 provided at the connection of the angle steels, and the adjacent angle steels are connected and fixed by the triangular connecting piece 3. The experimental frame 1 further includes a transverse angle steel 11 provided between the brackets to facilitate the placement of the test materials. The experimental box 4 includes no less than two PET boxes, and the PET boxes are all provided in the experimental frame 1, and the PET boxes can be equipped with salt solutions of different concentrations. In one embodiment, two PET boxes are provided, and ultrasonic atomizers 7 are installed inside the two PET boxes, and the two ultrasonic atomizers 7 are connected to transformers 6, and the two transformer 6 plugs are connected to the humidity controller 12 inside the experimental frame 1, and the humidity controller 12 is provided with a humidity probe 9, and the humidity probe 9 is located in the experimental frame 1.
[0041] In this embodiment, adjacent angle steels are interconnected and secured via triangular connecting pieces 3, facilitating both the construction of the test stand 1 and the timely disassembly and replacement of damaged components within the environmental simulation test apparatus. The solution in the PET cartridge can be replaced based on the needs of the environmental simulation, and any unused solution can be recycled and reused after the simulation is complete. This further improves the economic efficiency of the environmental simulation test apparatus.
[0042] Based on the above-mentioned environmental simulation test device, the working principle of the environmental simulation test device is as follows: the temperature and humidity of the environment can be monitored by the temperature probe 8 and the humidity probe 9, and the monitored data is transmitted to the temperature controller 5 and the humidity controller 12. When the temperature needs to be adjusted, the temperature controller 5 is started, and the temperature controller 5 can control the silica gel heating wire 10 to heat the experimental frame 1, thereby achieving temperature adjustment. The humidity controller 12 is started, and the humidity controller 12 can control the ultrasonic atomizer 7 to spray mist particles, thereby achieving adjustment of the humidity and salt spray concentration in the experimental device.
[0043] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0044] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and these variations and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
