Description

Technical Field

[0001] This invention relates to the field of material aging testing equipment technology, and in particular to a combined simulation device for material climate aging testing. Background Technology

[0002] Common materials in daily life, such as fabrics, car interiors, and flooring, are all subject to aging effects from the natural environment during use. These effects include sun exposure, rain, temperature, and humidity. Therefore, in order to test the expected service life of these materials during the production process, aging tests need to be conducted in test chambers to simulate the effects of climate aging. Existing test chambers can handle the temperature and humidity under normal climatic conditions, but when simulating some extreme climatic conditions, such as high temperature and high humidity, low temperature and low humidity, high temperature and low humidity, and low temperature and high humidity, the presence of high-temperature lamps inside the chamber makes it difficult to control the temperature and humidity under these extreme conditions using only external air circulation. This results in poor simulation effects and makes it impossible to accurately measure the expected service life of the test materials under the corresponding extreme conditions. Improvements are urgently needed. Summary of the Invention

[0003] To address the shortcomings of the aforementioned technologies, this invention provides a combined simulation device for material climate aging testing, comprising a test chamber, a sunlight and rain simulation device, a humidity control device, a rotating clamping platform, several adjustable clamping plates, and a sensor assembly, all housed within a test chamber. The test chamber has an air inlet, an air outlet, and a drain outlet. The sunlight and rain simulation device and the rotating clamping platform are both located within the test chamber. The humidity control device is connected to the air inlet of the test chamber. The several adjustable clamping plates are all mounted on the rotating clamping platform. The sensor assembly is located within the test chamber and on the adjustable clamping plates. The sunlight and rain simulation device includes a high-temperature lamp and a spray head. The sensor assembly includes a temperature and humidity sensor, an irradiance meter, and a black panel temperature sensor. The humidity control device includes a mist chamber, a temperature control component, a transmission pipe, and an adjustable spray head. The temperature control component is located within the mist chamber and connected to the temperature and humidity sensors via wiring. The water mist box is connected to an adjustable spray head via a transmission pipe. A humidity holding device is connected to one side of the test chamber. The humidity holding device includes an air inlet box, an air inlet fan, an air outlet channel, an upper partition, and a lower partition. The spray head, temperature and humidity sensor, and irradiance meter are all located below the upper partition. The black panel temperature sensor is located on the adjustable mounting plate. The air inlet box has an air inlet and an air outlet. The two ends of the air inlet fan are connected to the air outlet of the air inlet box and the air inlet of the test chamber, respectively. A vertical partition is provided inside the air inlet box. A mounting beam is provided between the vertical partition and the inner wall of the air inlet box. The adjustable spray head is located on the mounting beam. One end of the air outlet channel is connected to the air outlet of the test chamber. The upper and lower partitions are both located inside the test chamber and are located below the air outlet and above the air inlet, respectively. Both the upper and lower partitions have several ventilation holes.

[0004] Using the above technical solution, a humidity regulating device and a humidity maintaining device are installed around the test chamber. Water mist is generated by a mist chamber for air humidification, and the temperature of the water mist is controlled by a temperature control component inside the mist chamber. Finally, the water mist is delivered from an adjustable spray head through a transmission pipe. The adjustable spray head can also control the amount of water mist sprayed, thus controlling the air humidity. An air intake box is installed at the air inlet of the test chamber to buffer the incoming outside air. The adjustable spray head is placed inside the air intake box, and a vertical partition further increases the distance between it and the outside air, allowing the incoming outside air to be pre-conditioned in terms of temperature and humidity within the air intake box. A lower partition is installed above the air inlet inside the test chamber to further adjust the humidity. After the temperature and humidity are measured, the air passes through several ventilation holes in the lower partition and finally enters the test chamber. This ensures that the outside air enters the test chamber through multiple layers of partitions with stable and controllable temperature and humidity, and can maintain the temperature and humidity stability inside the test chamber for a relatively long time. An upper partition is installed below the air outlet in the test chamber, and an air outlet channel is set on the air outlet. This ensures smooth air circulation while maximizing the stability of the air temperature and humidity inside the test chamber. In this way, the temperature and humidity inside the test chamber can be adjusted by the operator to meet the requirements of some extreme weather conditions, such as "high temperature and high humidity, low temperature and low humidity, high temperature and low humidity, and low temperature and high humidity" for material climate aging simulation, thereby improving the accuracy of experimental results.

[0005] A further feature of the present invention is that an internal circulation device is provided between the air inlet box and the air outlet channel. The internal circulation device includes a circulation pipe, a circulation fan, and a circulation control mechanism. A circulation air outlet is opened on one side of the air inlet box. The circulation fan is installed on the circulation air outlet. The two ends of the circulation pipe are respectively connected to the circulation fan and the air outlet channel. The circulation control mechanism is installed on the air outlet channel near the air outlet of the test chamber.

[0006] By adopting the above technical solution, an internal circulation device is provided between the air inlet box and the air outlet channel. The internal circulation device includes a circulation pipe, a circulation fan, and a circulation control mechanism. A circulation air outlet is opened on one side of the air outlet of the air inlet box. The circulation fan is installed on the circulation air outlet. The two ends of the circulation pipe are connected to the circulation fan and the air outlet channel, respectively. The circulation control mechanism is installed on the air outlet channel near the air outlet of the test chamber. After being regulated by the circulation control mechanism, part of the air discharged from the air outlet channel can flow back to the circulation air outlet of the air inlet box through the circulation pipe, and then flow back into the air inlet box under the action of the circulation fan. After this treatment, the fogging requirement required to maintain the air temperature and humidity in the test chamber can be greatly reduced, making it easier to maintain the extreme temperature and humidity conditions in the test chamber. At the same time, according to the actual air temperature and humidity requirements in the test chamber, the air discharged from the test chamber can be distributed by the circulation control mechanism, and the ratio of air entering the circulation and air discharged from the chamber can be freely adjusted.

[0007] A further feature of the present invention is as follows: the circulating air control mechanism includes a mounting plate, a drive motor, a control unit, an airflow regulating baffle, and a mounting shaft. The mounting shaft is fixedly mounted on the airflow regulating baffle, the shape and size of which match the opening of the air outlet channel. The mounting plate is located on the outside of the air outlet channel. The control unit and the drive motor are both mounted on the mounting plate. One end of the mounting shaft is rotatably connected to the inner wall of the air outlet channel, and the other end passes through the side wall of the air outlet channel and is connected to the drive motor. The drive motor is connected to a temperature and humidity sensor through the control unit.

[0008] Using the above technical solution, the circulating air control mechanism includes a mounting plate, a drive motor, a control unit, an airflow regulating baffle, and a mounting shaft. The mounting shaft is fixedly mounted on the airflow regulating baffle, the shape and size of which match the opening of the air outlet channel. The mounting plate is located on the outside of the air outlet channel. The control unit and the drive motor are both mounted on the mounting plate. One end of the mounting shaft is rotatably connected to the inner wall of the air outlet channel, and the other end passes through the side wall of the air outlet channel and is connected to the drive motor. The drive motor is connected to a temperature and humidity sensor through the control unit, so that after the air discharged from the air outlet comes into contact with the airflow regulating baffle, part of it is discharged upward from the opening of the air outlet channel, and the other part is discharged downward into the circulation pipe. The drive motor can control the rotation of the airflow regulating baffle based on the humidity sensor's measurement and the control unit's adjustment, thereby controlling the opening range of the air outlet channel.

[0009] A further feature of the present invention is that a circulating air baffle is provided inside the air intake box below the circulating fan, and the two ends of the circulating air baffle are respectively connected to the vertical baffle and the inner wall of the air intake box.

[0010] By adopting the above technical solution, since a circulating air baffle is also provided in the air intake box below the circulating fan, and the two ends of the circulating air baffle are respectively connected to the vertical baffle and the inner wall of the air intake box, the circulating air is prevented from directly contacting the air inlet of the air intake box, and can be directly returned to the test chamber through the air intake fan to the greatest extent.

[0011] A further feature of the present invention is that a secondary temperature control mechanism for mist is provided in the test chamber below the lower partition, and the secondary temperature control mechanism for mist is connected to a temperature and humidity sensor.

[0012] By adopting the above technical solution, since a secondary temperature control mechanism for mist is also provided in the test chamber below the lower partition, and the secondary temperature control mechanism for mist is connected to a temperature and humidity sensor, the air entering from the air inlet can be further controlled and stabilized by the secondary temperature control mechanism before entering the test chamber through the air flow hole of the lower partition, thereby further ensuring the stability of the air temperature in the test chamber.

[0013] A further feature of the present invention is that a pair of mist guide plates are provided inside the test chamber at a position above the upper partition.

[0014] By adopting the above technical solution, since a pair of mist guide plates are provided in the test chamber above the upper partition, the air discharged from the test chamber can be smoothly discharged from the air outlet under the guidance of the mist guide plates.

Detailed Implementation

[0022] like Figure 1-6As shown, a combined simulation device for material climate aging testing includes a test chamber 1, a sunlight and rain simulation device 2, a humidity control device 3, a rotating clamping platform 4, several adjustable clamping plates 4, and a sensor group, all housed within a test chamber. The test chamber has an air inlet 5, an air outlet 6, and a drain outlet. The sunlight and rain simulation device and the rotating clamping platform are both located within the test chamber. The humidity control device is connected to the air inlet of the test chamber. The several adjustable clamping plates are all located on the rotating clamping platform. The sensor group is located within the test chamber and on the adjustable clamping plates. The sunlight and rain simulation device includes a high-temperature lamp 7 and a spray head 8. The sensor group includes a temperature and humidity sensor 9, an irradiance meter 10, and a blackboard temperature sensor 11. The humidity control device includes a water mist chamber 12, a temperature control component 13, a transmission pipe 14, and an adjustable spray head 15. The temperature control component is located within the water mist chamber and connected to the temperature and humidity sensor via a connecting line. The chamber is connected to an adjustable spray head via a transmission pipe. A humidity holding device 16 is connected to one side of the test chamber. The humidity holding device includes an air inlet box 17, an air inlet fan 18, an air outlet channel 19, an upper partition 20, and a lower partition 21. The spray head, temperature and humidity sensor, and irradiance meter are all located below the upper partition. The black panel temperature sensor is located on the adjustable mounting plate. The air inlet box has an air inlet 22 and an air outlet 23. The air inlet fan has two ends... The air inlet of the air inlet box and the air inlet of the test chamber are connected respectively. The air inlet box is provided with a vertical partition 24. A mounting beam 25 is provided between the vertical partition and the inner wall of the air inlet box. The adjustable spray head is set on the mounting beam. One end of the air outlet channel is connected to the air outlet of the test chamber. The upper partition and the lower partition are both set in the test chamber and are located below the air outlet and above the air inlet, respectively. The upper partition and the lower partition are provided with a number of air passage holes 26.

[0023] Humidity regulating and maintaining devices are installed around the test chamber. A water mist chamber generates water mist for air humidification, and a temperature control component within the chamber regulates the mist's temperature. The mist is then delivered through a transmission pipe from an adjustable spray head, which also controls the amount of mist sprayed, thus controlling air humidity. An air intake box is installed at the test chamber's air inlet to buffer incoming outside air. The adjustable spray head is placed inside the air intake box, and a vertical baffle further separates it from the outside air, pre-regulating the temperature and humidity of incoming outside air within the air intake box. A lower baffle is installed above the air inlet inside the test chamber to further regulate the temperature and humidity. The air passes through several ventilation holes in the lower partition and finally enters the test chamber, ensuring that the outside air enters the test chamber with stable and controllable temperature and humidity after passing through multiple layers, and can maintain the temperature and humidity stability in the test chamber for a relatively long time. An upper partition is set below the air outlet in the test chamber, and an air outlet channel is set on the air outlet. While ensuring smooth air circulation, the temperature and humidity of the air in the test chamber are kept as stable as possible. In this way, the temperature and humidity in the test chamber can be adjusted by the operator to meet the requirements of some extreme weather conditions, such as "high temperature and high humidity, low temperature and low humidity, high temperature and low humidity, and low temperature and high humidity" for material climate aging simulation, thereby improving the accuracy of experimental results.

[0024] An internal circulation device 27 is also provided between the air inlet box and the air outlet channel. The internal circulation device includes a circulation pipe 28, a circulation fan 29, and a circulation control mechanism 30. A circulation air outlet 31 is opened on one side of the air inlet on the air inlet box. The circulation fan is set on the circulation air outlet. The two ends of the circulation pipe are respectively connected to the circulation fan and the air outlet channel. The circulation control mechanism is set on the air outlet channel near the air outlet of the test chamber.

[0025] Because an internal circulation device is provided between the air inlet box and the air outlet channel, the internal circulation device includes a circulation pipe, a circulation fan, and a circulation control mechanism. A circulation air outlet is opened on one side of the air outlet of the air inlet box. The circulation fan is installed on the circulation air outlet. The two ends of the circulation pipe are connected to the circulation fan and the air outlet channel, respectively. The circulation control mechanism is installed on the air outlet channel near the air outlet of the test chamber. After being regulated by the circulation control mechanism, part of the air discharged from the air outlet channel can flow back to the circulation air outlet of the air inlet box through the circulation pipe, and then flow back into the air inlet box under the action of the circulation fan. After this treatment, the fogging requirement required to maintain the air temperature and humidity in the test chamber can be greatly reduced, making it easier to maintain the extreme temperature and humidity conditions in the test chamber. At the same time, according to the actual air temperature and humidity requirements in the test chamber, the air discharged from the test chamber can be distributed by the circulation control mechanism, and the ratio of air entering the circulation and air discharged from the chamber can be freely adjusted.

[0026] The circulating air control mechanism includes a mounting plate 32, a drive motor 33, a control unit 39, an airflow regulating baffle 34, and a mounting shaft 35. The mounting shaft is fixedly mounted on the airflow regulating baffle, the shape and size of which match the opening of the air outlet channel. The mounting plate is located on the outside of the air outlet channel. The control unit and the drive motor are both mounted on the mounting plate. One end of the mounting shaft is rotatably connected to the inner wall of the air outlet channel, and the other end passes through the side wall of the air outlet channel and is connected to the drive motor. The drive motor is connected to a temperature and humidity sensor through the control unit.

[0027] The circulating air control mechanism includes a mounting plate, a drive motor, a control unit, an airflow regulating baffle, and a mounting shaft. The mounting shaft is fixedly mounted on the airflow regulating baffle, the shape and size of which match the opening of the air outlet channel. The mounting plate is located on the outside of the air outlet channel. Both the control unit and the drive motor are mounted on the mounting plate. One end of the mounting shaft is rotatably connected to the inner wall of the air outlet channel, and the other end passes through the side wall of the air outlet channel and is connected to the drive motor. The drive motor is connected to a temperature and humidity sensor via the control unit. This allows the air discharged from the outlet to come into contact with the airflow regulating baffle, with some air flowing upwards out of the air outlet channel and the rest flowing downwards into the circulation pipe. The drive motor can control the rotation of the airflow regulating baffle based on the humidity sensor readings and the control unit's adjustment, thereby controlling the opening width of the air outlet channel.

[0028] A circulating air baffle 36 is also provided inside the air intake box, located below the circulating fan. The two ends of the circulating air baffle are connected to the vertical baffle and the inner wall of the air intake box, respectively.

[0029] Because a circulating air baffle is also provided in the air intake box below the circulating fan, and the two ends of the circulating air baffle are connected to the vertical baffle and the inner wall of the air intake box respectively, the circulating air is prevented from directly contacting the air inlet of the air intake box, and can be directly returned to the test chamber through the air intake fan to the greatest extent.

[0030] The test chamber is also equipped with a secondary mist temperature control mechanism 37 located below the lower partition plate. The secondary mist temperature control mechanism is connected to a temperature and humidity sensor.

[0031] Because a secondary temperature control mechanism for misting is also provided in the test chamber below the lower partition, and the secondary temperature control mechanism for misting is connected to a temperature and humidity sensor, the air entering from the air inlet can be further controlled and stabilized by the secondary temperature control mechanism before entering the test chamber through the air flow hole of the lower partition, thereby further ensuring the stability of the air temperature in the test chamber.

[0032] A pair of mist guide plates 38 are also provided in the test chamber above the upper partition.

[0033] Because a pair of mist guide plates are provided above the upper partition in the test chamber, the air discharged from the test chamber can be smoothly discharged from the air outlet under the guidance of the mist guide plates.
