Therefore, research into the corrosion patterns of materials in salt spray environments is crucial for influencing the reliability of materials used in future products and facilitating subsequent product design. However, current measuring devices are limited in function and cannot simulate corrosion levels under diverse operating conditions, rendering the measurement data insufficient for effective support. Utility Model Content

[0003] This utility model provides a marine air-cooled corrosion measurement device, which aims to solve the problem that the existing corrosion measurement devices have relatively simple functions and the data cannot provide effective experimental support.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a marine air-cooled corrosion measurement device, comprising:

[0005] Ventilation ducts;

[0006] A fan, installed at the front end of the ventilation duct, is used to deliver outside air into the ventilation duct.

[0007] A flow meter, installed behind the fan along the airflow direction inside the ventilation duct, is used to detect the air volume inside the ventilation duct.

[0008] The test section, installed behind the flow meter, is used to detect the amount of corrosion in the air inside the ventilation duct;

[0009] A heating section, installed in front of the test section, is used to control the temperature of the air inside the ventilation duct.

[0010] In one possible implementation, the heating section is located in front of the fan.

[0011] In one possible implementation, a gas-liquid separator is also installed at the air inlet of the ventilation duct, and the gas-liquid separator is located in front of the heating section.

[0012] In one possible implementation, the front end of the ventilation duct is further equipped with a first air valve for controlling the airflow state, the first air valve being installed between the gas-liquid separator and the heating section.

[0013] In one possible implementation, a filter pipe is also connected to the air inlet of the test section, the filter pipe being used to filter dust and debris in the air.

[0014] In one possible implementation, a meteorological observation box for detecting the amount of corrosion in the external environment is also installed on the outside of the test section.

[0015] In one possible implementation, the meteorological observation box includes louvers installed on the side wall of the meteorological observation box and a first detection module installed inside the meteorological observation box.

[0016] In one possible implementation, the test section is equipped with multiple detection modules, the detection modules including:

[0017] A housing is installed inside the test section, and the housing has ventilation holes that communicate with the interior of the test section.

[0018] A heater is mounted on the housing and located at the air inlet of the ventilation hole;

[0019] The second detection module is installed inside the ventilation hole and located behind the heater, and is used to detect the amount of corrosion in the air inside the ventilation hole.

[0027] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] Please refer to the following: Figures 1 to 3 The marine air-cooled corrosion measuring device provided by this utility model will now be described. The marine air-cooled corrosion measuring device includes a ventilation duct 1, a fan 2, a flow meter 3, a test section 4, and a heating section 5. The fan 2 is installed at the front of the ventilation duct 1 to deliver outside air into the ventilation duct 1; the flow meter 3 is installed behind the fan 2 along the airflow direction inside the ventilation duct 1 to detect the airflow rate inside the ventilation duct 1; the test section 4 is installed behind the flow meter 3 to detect the amount of corrosion in the air inside the ventilation duct 1; and the heating section 5 is installed in front of the test section 4 to control the temperature of the air inside the ventilation duct 1.

[0029] The marine air-cooled corrosion measurement device provided in this embodiment, compared with the prior art, features a ventilation duct 1 with a fan 2 installed at the front. The fan 2 is an axial flow fan used to deliver air to the test section 4 at the rear. Inside the ventilation duct 1, a flow meter 3 and a heating section 5 are also installed, both located in front of the test section 4. The flow meter 3 detects the airflow inside the ventilation duct 1 and is electrically connected to a controller, which is electrically connected to the fan 2. The flow meter 3 feeds back the measured values ​​to the controller, which then controls the fan 2's operation to adjust the airflow inside the ventilation duct 1. This allows for the regulation and control of the airflow and temperature passing through the test section 4. In this application, during on-site testing, the airflow and temperature inside the ventilation duct 1 can be adjusted through the flow meter 3 and the heating section 5, enabling simulated corrosion testing under different environments. This provides corrosion measurement data for various conditions, offering a valuable reference for the material selection of subsequent products.

[0030] Specifically, in this embodiment, the flow meter 3 is an orifice plate flow meter 3, and the control methods and techniques of the flow meter 3, the controller, and the fan 2 are all existing technologies. The control circuit of the controller can be implemented by those skilled in the art through simple programming. Furthermore, this document is mainly used to protect mechanical devices, and the control methods and circuit connections will not be explained in detail here.

[0031] Specifically, in this embodiment, the front section of the pipeline includes a first pipeline and a second pipeline, and the air inlet and outlet of the fan 2 are connected to the two ends of the first pipeline and the second pipeline through flanges.

[0032] In some embodiments, the heating section 5 described above can be as follows: Figure 1 The structure shown. See also Figure 1 Heating section 5 is located in front of fan 2. Heating section 5 uses finned resistance wire and, being in front of fan 2, provides a certain degree of dehumidification. Fan 2 is installed in the middle of the front section of ventilation duct 1. Fan 2 draws outside air into ventilation duct 1 and delivers it to test section 4. When the air flows to heating section 5, it is heated. This allows simulation of the effect of air at different temperatures on corrosion levels.

[0033] Specifically, in this embodiment, multiple finned resistance wires are fixedly installed on the side wall of the heating section 5 of the ventilation duct 1, and the heating section 5 of the finned resistance wires is located inside the ventilation duct 1.

[0034] In some embodiments, the ventilation duct 1 described above may be as follows: Figure 1 The structure shown. See also Figure 1A gas-liquid separator 6 is also installed at the air inlet of ventilation duct 1, located in front of heating section 5. The gas-liquid separator 6 filters out moisture from the air, preventing excessive moisture inside ventilation duct 1 from affecting subsequent testing data or the lifespan of various working or testing components.

[0035] In some embodiments, the ventilation duct 1 described above may be as follows: Figure 1 The structure shown. See also Figure 1 The ventilation duct 1 is equipped with a first air valve 7 at its front end to control airflow. The first air valve 7 is installed between the gas-liquid separator 6 and the heating section 5. The first air valve 7 controls the ventilation state inside the ventilation duct 1. After a specified time, the ventilation duct 1 can be closed by shutting down the first air valve 7, simultaneously turning off the fan 2. When detection begins, the first air valve 7 can be opened first, followed by the fan 2, thus allowing for flexible control of the airflow state in the ventilation duct 1 based on the set time and detection status.

[0036] In some embodiments, test segment 4 described above can be adopted as follows: Figure 1 The structure shown. See also Figure 1 A filter tube 8 is also connected to the air inlet of test section 4. The filter tube 8 is used to filter dust and debris in the air. The filter tube 8 is also connected to the air inlet of test section 4. Filter cotton is installed inside the filter tube 8. The filter cotton can filter out dust and debris in the air and provide a good air environment for test section 4.

[0037] In some embodiments, test segment 4 described above can be adopted as follows: Figure 2 The structure shown. See also Figure 2 A meteorological observation box 41 for detecting corrosion in the external environment is also installed on the outside of test section 4. The meteorological observation box 41 is fixedly installed on the top of test section 4, and is installed outside the ventilation duct 1. The interior of the meteorological observation box 41 is connected to the external environment, allowing it to detect corrosion values ​​under natural conditions, thus providing a certain basis for assessing corrosion levels. Therefore, corrosion detection data under various operating environments can be simulated based on the detection data from test section 4 and the meteorological observation box 41.

[0038] In some embodiments, the meteorological observation box 41 described above can be adopted as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2The meteorological observation box 41 includes louvers 411 installed on the side wall of the meteorological observation box 41 and a first detection module 412 installed inside the meteorological observation box 41. The louvers 411 are installed on the side wall of the meteorological observation box 41, and filter cotton is installed on the side of the louvers 411 to simulate the corrosion level of the control cabinet under natural conditions. The first detection module 412, which consists of a corrosion block and a corrosion sensor, is installed inside the meteorological observation box 41 to facilitate the simulation of corrosion levels under natural conditions over a specific monitoring period.

[0039] Specifically, in this embodiment, the corrosion sensor is existing technology, such as a corrosion rate probe. The specific detection methods and procedures can be understood by those skilled in the art based on existing technology, and therefore will not be described further here.

[0040] In some embodiments, test segment 4 described above can be adopted as follows: Figure 3 The structure shown. See also Figure 3 The test section 4 contains multiple detection modules 42, each including a housing 421, a heater 422, and a second detection module 423. The housing 421 is installed inside the test section 4 and has ventilation holes communicating with the interior of the test section 4. The heater 422 is mounted on the housing 421 and located at the air inlet of the ventilation hole. The second detection module 423 is installed inside the ventilation hole and located behind the heater 422, used to detect the amount of corrosion in the air inside the ventilation hole. The test section 4 is located in the rear half of the ventilation duct 1. Multiple detection modules 42 are also installed inside the test section 4. Each detection module 42 includes a housing 421 installed inside the test section 4. The housing 421 has ventilation holes that penetrate the housing 421 and are oriented along the length of the ventilation duct 1, with both ends of the ventilation holes located at both ends of the housing 421. A heater 422 is installed at the end near the air inlet of the ventilation hole, along the airflow direction. A second detection module 423 is installed inside the ventilation hole near the air outlet. The second detection module 423 has the same structure as the first detection module 412, both containing a corrosion block and a corrosion sensor for detecting the corrosion block. By setting up multiple detection modules 42, the ambient temperature inside multiple housings 421 can be adjusted via a heater 422 to create different temperature and humidity conditions. This allows for the determination of the corrosion status of the corrosion block under different environments.

[0041] In some embodiments, the ventilation duct 1 described above may be as follows: Figure 1 The structure shown. See also Figure 1A second air valve 9 is installed at the air outlet of ventilation duct 1 to control the ventilation status inside ventilation duct 1. The second air valve 9 is located behind test section 4. A first air valve 7 is installed at the air inlet of ventilation duct 1, and a second air valve 9 is installed at the air outlet of the air inlet duct. After the experiment is completed, the first air valve 7 and the second air valve 9 are closed to prevent outside air from corroding the instruments inside ventilation duct 1, thus protecting the instruments inside the duct.

[0042] Preferably, in this embodiment, the end of the ventilation duct 1 with an air outlet is connected to an elbow, and the air outlet of the elbow is bent downwards. This can further prevent outside air from entering the ventilation duct 1.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
