Description

Technical Field

[0001] This utility model relates to the technical field of testing building waterproof and anti-corrosion materials, specifically to a testing device for conducting aging tests on building protective films. Background Technology

[0002] Xenon lamp aging test chambers primarily test a product's weather resistance by simulating external climatic conditions such as solar radiation, temperature, and humidity through accelerated aging experiments. Typically, a turntable is installed inside the chamber, with multiple samples to be tested arranged evenly in a ring around a xenon lamp at the top. This ensures that each sample receives uniform light radiation, spray, or heating. Multiple sensors are also installed inside the chamber to collect various data from the sample surface, such as temperature and humidity. However, because the samples rotate continuously with the turntable during the test, the sensors, due to their fixed signal cables, cannot be mounted on the turntable like the samples. Therefore, the sensors are generally fixed at a distance from the samples, such as on the side wall of the chamber. Consequently, the data collected by the sensors has a certain degree of error compared to the actual values. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an aging test chamber that can install sensors close to the sample without affecting the sample's rotation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An aging test chamber for testing building protective films includes a frame inside the chamber, a turntable positioned above the frame, and a drive assembly installed below the frame to drive the turntable to rotate. Sensors are suspended on the turntable.

[0006] The turntable forms a ring-shaped groove, and multiple hollow pipes are fixed around the outer perimeter of the turntable. The hollow pipes pass above the turntable and then extend downward into the groove. The signal lines of the sensor are led out from the hollow pipes.

[0007] The drive assembly includes a drive motor, a pair of meshing helical gears, and a drive shaft. The helical gears are respectively mounted on the output shaft of the drive motor and the drive shaft, and the top end of the drive shaft is connected to the center of the turntable.

[0008] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0009] This invention features a groove on the turntable to suspend the sensor probe within it, with the signal line led out from above the turntable via a hollow pipe. This design ensures that the sensor is close to the sample under test and at roughly the same height from the top xenon lamp without affecting the turntable's rotation, allowing for more accurate detection of sample aging under various simulated environments such as solar radiation, temperature, and humidity.

[0012] Figure 3 for Figure 1 Top view; Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages 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.

[0014] Example

[0015] See Figure 1 A schematic diagram of the interior of the chamber (the chamber body and doors are not shown). The aging test chamber includes a frame 1 inside the chamber, a turntable 2 set above the frame 1, a drive assembly installed below the turntable 2, and a drive assembly for driving the turntable 2 to rotate.

[0016] The drive assembly includes a drive motor 31, a pair of meshing helical gears 32, and a drive shaft 33. The helical gears 32 are respectively mounted on the output shaft of the drive motor 31 and the drive shaft 33. The top end of the drive shaft 33 is connected to the center of the turntable 2. Under the action of the drive motor 31 and the gears, the drive shaft 33 is rotated, thereby driving the turntable 2 to rotate.

[0017] The turntable 2 is used to place multiple samples 4 to be tested, which are evenly arranged in a ring on the turntable 2. Multiple sets of sensors 5 are also installed on the turntable 2. In this embodiment, there are 4 sets. The sensors can be temperature sensors, humidity sensors, light sensors, etc. The turntable 2 forms a ring-shaped groove 21 around the center. The probes at the ends of the multiple sensors 5 are suspended in the groove 21, and are approximately at the same height as the samples 4.

[0018] Multiple hollow pipes 7 are installed around the turntable 2, arranged in a ring around the turntable 2, with the number corresponding to the number of sensor groups 5. Each hollow pipe 7 is fixed to the perimeter, extending from the top of the turntable 2 into the groove 21, allowing the signal lines of each sensor group 5 to pass through the hollow pipes 7 and connect to the control system. This suspends the sensor 5 within the groove 21, ensuring that the signal lines of the sensor 5 do not obstruct the rotation of the turntable 2 during aging tests. The sensor 5 is relatively close to the sample under test, and both are at approximately the same height from the xenon lamp at the top of the chamber, allowing for more accurate detection of the product's aging under simulated solar radiation, temperature, and humidity conditions.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
