[0040] The rain test of the aircraft is usually carried out in a climate environment laboratory which can simulate various climate environments. The climate environment laboratory refers to a laboratory in which various climate environments can be simulated, and the rain environment is one of the simulated environments.

[0041] The rain test device provided by the present application is used for the rain test of the aircraft door, and the rain test is used for studying the sealing performance and the drainage performance of the door. The sealing performance of the door is closely related to the flight safety of the aircraft, and the sealing performance is also directly related to the airworthiness certification. The traditional rain test method is to manually use a water pipe to spray around the door. This method not only cannot guarantee the uniformity of the spraying, but also cannot guarantee that the spraying angle is perpendicular to the door. At the same time, the traditional leakage detection method can only check the position by visual inspection, and cannot obtain the leakage data.

[0042] Therefore, the present application provides a rain test device and a control method thereof, which can realize accurate measurement of leakage. The following will be described in detail. It should be noted that the description order of the following embodiments is not limited as the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis, and the parts not described in detail in a certain embodiment can be referred to the related description of other embodiments.

[0043] Reference Figures 1-3The rain test device is used for carrying out the rain test on the test piece 100, and comprises a base 10, a spraying module 20, a water return module 30, a posture adjusting module 40 and a measuring module 50. The base 10 is used for carrying the above-mentioned modules, so that the rain test device constitutes an integrated modular device, facilitating subsequent handling. The spraying module 20 comprises a spraying support 201, a spraying pipeline and a plurality of spray heads 202. The spraying support 201 is arranged on the base 10 and supports and fixes the spraying pipeline. The plurality of spray heads 202 are communicated with the spraying pipeline to spray the water in the spraying pipeline to the test piece 100. The water return module 30 comprises a water collecting tank 301 and a water return assembly 302. The water collecting tank 301 is arranged below the base 10 to collect the water sprayed by the spray heads 202 to the test piece 100. The water return assembly 302 is arranged on the base 10 to deliver the water in the water collecting tank 301 to the spraying pipeline. The posture adjusting module 40 is arranged on the base 10 and connected with the test piece 100, and can adjust the posture of the test piece 100 to match the position of the spraying module 20, so as to ensure that the spraying direction of the spray heads 202 in the spraying module 20 is perpendicular to the test piece 100. The measuring module 50 comprises a collecting piece 501 and a measuring assembly. The collecting piece 501 is connected to the side of the test piece 100 which is opposite to the spraying module 20, and the collecting piece 501 is provided with a water outlet 5011. After the rain test is completed, the spraying pipeline is cut off, and the posture of the test piece 100 is adjusted by the posture adjusting module 40, so that the collecting piece 501 is close to the base 10 relative to the test piece 100, to collect the leakage water of the test piece 100. The leakage water is discharged to the measuring assembly through the water outlet 5011 to obtain the corresponding leakage water amount information.

[0044] In specific use, the posture adjustment module 40 is used to adjust the posture of the test piece 100, so that the position of the spraying module 20 matches the position of the test piece 100, and the water sprayed by the spray head 202 of the spraying module 20 can be accurately sprayed on the test piece 100, so as to test the sealing performance and drainage performance of the test piece 100. When the spraying water is sprayed on the test piece 100, it will flow downward along the test piece 100 under the action of gravity, and then be collected in the water collecting tank 301 of the water collecting module 30, and then be re-delivered to the spraying pipeline through the water collecting assembly 302 and sprayed out through the spray head 202, so as to realize the recycling of the spraying water. After the spraying module 20 operates for a period of time, it is confirmed that the rain test is completed, and then the spraying pipeline is cut off to prevent the spray head 202 from continuing to spray water. The posture adjustment module 40 adjusts the posture of the test piece 100, and rotates the test piece 100 by an angle, so that the collecting piece 501 is close to the base 10 relative to the test piece 100, that is, the collecting piece 501 is located below the test piece 100. If the sealing performance of the test piece 100 is poor, a part of the water will seep from one side of the test piece 100 to the other side of the test piece 100, and then be collected in the collecting piece 501 under the action of gravity. Subsequently, the measuring assembly is used to measure the leakage water amount information of the leakage water, so as to realize the automatic rain test of the test piece 100, and the measuring module can be used to measure the leakage water amount information of the leakage water, so as to realize the accurate measurement of the waterproof performance of the test piece 100.

[0045] It can be understood that, generally, the water sprayed by the spraying module 20 is directly sprayed to the outer side of the test piece 100, and the collecting piece 501 is connected to the inner side of the test piece 100. Specifically, the outer side of the test piece 100 is the outer wall surface of the test piece 100 exposed outside the fuselage when the test piece 100 is installed on the fuselage of the aircraft. The inner side of the test piece 100 is the inner wall surface of the test piece 100 located in the cabin of the fuselage when the test piece 100 is installed on the fuselage of the aircraft. For example, the above-mentioned measuring assembly can be a weighing mechanism, which is used to obtain the weight parameter of the leakage water, and the leakage water amount information includes the leakage water amount. Alternatively, the above-mentioned measuring assembly includes a graduated measuring cup, which can collect water in the measuring cup through the drainage port 5011, and obtain the weight parameter of the leakage water by observing the relationship between the scale line on the measuring cup and the water surface. In order to realize the collection of the spraying water, the above-mentioned water collecting tank 301 is arranged at the bottom of the whole rain test device, and the base 10 is arranged in the water collecting tank 301, and the projections of the base 10, the spraying module 20, the water collecting module 30, the posture adjustment module 40 and the measuring module 50 are located in the water collecting tank 301, so as to ensure that the spraying water can be completely collected in the water collecting tank 301.

[0046] And the posture adjustment module 40 can also realize multi-posture adjustment of the test piece 100. For example, when conducting a spray test, the posture adjustment module 40 can drive the test piece 100 to adjust the posture, so as to reproduce the posture scene of the test piece 100 (the cabin door) in various actual applications such as airplane parking, climbing and landing, and further improve the accuracy of the rain test.

[0047] In addition, the measurement assembly in the measurement module 50 measures the corresponding leakage water amount information, which can also be used to correct the spray module 20 and the posture adjustment module 40. For example, if the measurement assembly does not measure the leakage water amount, that is, the test piece 100 does not leak, at this time, the position of the spray module 20 and / or the posture adjustment module 40 can be further adjusted, so that the spray module 20 is closer to the test piece 100, and the spray test is started.

[0048] In order to obtain the leakage position and leakage time of the test piece 100, the measurement module 50 further comprises a monitoring assembly 502, which is arranged on the base 10 and located on the side of the test piece 100 facing the collection piece 501.

[0049] In some embodiments, the collection piece 501 is a transparent cover plate, and the monitoring assembly 502 comprises a visual acquisition assembly, which is fixed and supported on the base 10 by a first support 503 and located on the side of the test piece 100 close to the cover plate, so as to acquire image information of the test piece 100. Before the rain test, a dry-wet indicator is coated on the side of the test piece 100 close to the cover plate, and then the cover plate is installed on the side of the test piece 100 facing away from the spray module 20. Based on the performance of the dry-wet indicator changing color when encountering water, the image information acquired by the visual acquisition assembly will change, and the visual acquisition assembly can confirm the leakage position and leakage time of the test piece 100 according to the image information. That is, the visual acquisition assembly can acquire image information of the inner wall surface of the test piece 100 in real time. At the same time, the visual acquisition assembly can provide high-resolution image information, which can capture small leakage positions and changes, help to accurately locate the leakage point, and improve the accuracy of detection. In addition, the acquired image information can be processed and analyzed to determine the leakage position and leakage time, so that the monitoring result is more intuitive and visual, and it is convenient for the operator to analyze and judge. In specific use, the visual acquisition assembly only needs to be directed towards the inner wall surface of the test piece 100, which will not affect the integrity and function of the test piece 100. For example, the dry-wet indicator can be a color-changing ink, a dry-wet color-changing film, a color-changing sticker, a color-changing silica gel, or other materials that change color after absorbing moisture.

[0050] In other embodiments, the monitoring component includes multiple humidity sensors (not shown in the accompanying drawings), which are respectively arranged at different positions on the side of the test piece 100 facing the collecting member 501, and are used to collect humidity information at different positions of the test piece 100 to obtain the leakage position and leakage time of the test piece 100. By arranging multiple humidity sensors at different positions, multiple positions of the test piece 100 can be monitored simultaneously to more comprehensively understand the leakage situation of the test piece 100 and avoid omissions or misjudgments. In addition, the humidity sensor can collect humidity information in real time to promptly detect leakage of the test piece 100. Each humidity sensor can independently record and store humidity data and has an independent identifier, so that the leakage situation at each position can be traced, which is convenient for subsequent data analysis and troubleshooting.

[0051] It should be noted that in some embodiments, the monitoring component 502 may only include a visual acquisition component, in some embodiments, the monitoring component may only include a humidity sensor, and in some embodiments, the monitoring component 502 may include both a visual acquisition component and a humidity sensor to simultaneously combine the advantages of both detection methods.

[0052] like Figure 2 and Figure 4 As shown, in order to achieve multi-directional and multi-angle adjustment of the test piece 100 to ensure that the spray water sprayed by the nozzle 202 in the spray module 20 is accurately sprayed onto the test piece 100, it is assumed that the rain test device provided in this application includes a first direction Z, a second direction X and a third direction Y that intersect with each other. The above-mentioned attitude adjustment module 40 includes a rotation module 401, a pitch adjustment module 402 and a movement adjustment module 403. The rotation module 401 is installed in the water collection tank 301 and is connected to the bottom of the base 10 to drive the base 10 to rotate around the first direction Z. The pitch adjustment module 402 includes a fixed bracket 4021 and a pitch driving member 4022. The fixed bracket 4021 is provided on the base 10, and the pitch driving member 4022 is provided on the fixed bracket 4021. The movement and adjustment module 403 includes a mounting bracket 4031, a longitudinal movement assembly 4032, and a horizontal movement assembly 4033. The mounting bracket 4031 is fixedly connected to the pitch actuator 4022. The longitudinal movement assembly 4032 is provided on the mounting bracket 4031 to adjust the position of the test piece 100 in the first direction Z. The horizontal movement assembly 4033 is provided on the mounting bracket 4031 to adjust the position of the test piece 100 in the second direction X. The pitch actuator 4022 is used to drive the mounting bracket 4031 to rotate about the third direction Y. For example, the base 10 has a plate-like structure.

[0053] In specific use, the pitching driving member 4022 can drive the movement adjustment module 403 mounted on the mounting bracket 4031 to rotate synchronously with the test piece 100 around the third direction Y, so as to drive the test piece 100 to switch between the spraying position and the collecting position. In the spraying position, the pitching adjustment module 402 drives the test piece 100 to rotate, so that the position of the test piece 100 is opposite to the spraying module 20. Specifically, there are multiple spraying positions to simulate different scenarios of the test piece 100 (the cabin door) in different attitudes during the flight of the aircraft, and then spray the test piece 100. In the collecting position, the pitching adjustment module 402 drives the test piece 100 to rotate, and the position of the test piece 100 is away from the position of the collecting piece 501 and is in a substantially horizontal state. For example, the pitching driving member 4022 includes a pitching driving motor or a hand wheel, which can drive the mounting bracket 4031 and the remaining components mounted on the mounting bracket 4031 to rotate around the third direction Y, thereby realizing the rotation of the cabin door mounted on the mounting bracket 4031 around the third direction Y.

[0054] In some embodiments, in order to reduce the manufacturing cost of the rain test device, the mounting bracket 4031 includes two mounting columns 40311 spaced apart along the third direction Y, and a bearing plate 40312 connected between the two mounting columns 40311. The longitudinal movement assembly 4032 includes a plurality of first spacers, and the position adjustment of the test piece 100 in the first direction Z can be realized by arranging different numbers of first spacers between the bottom of the test piece 100 and the bearing plate 40312. The horizontal movement assembly 4033 includes a plurality of second spacers, and the position adjustment of the test piece 100 in the second direction X can be realized by clamping different numbers of second spacers between the test piece 100 and the mounting columns 40311.

[0055] In some embodiments, in order to realize the automation of the rain test device, the longitudinal moving assembly 4032 comprises a longitudinal driving member, a slide rail and a sliding block, the slide rail extends along the first direction Z and is provided with a sliding groove extending along the first direction Z, the sliding block is slidingly fitted in the sliding groove, the longitudinal driving member is used to drive the sliding block to slide in the sliding groove, and the test piece 100 is connected with the sliding block. The horizontal moving assembly 4033 is arranged on the mounting bracket 4031 and is in transmission connection with the bottom end of the slide rail, and the horizontal moving assembly 4033 drives the slide rail to move along the second direction X. In other words, the horizontal moving assembly 4033 is directly connected with the mounting bracket 4031, and the longitudinal moving assembly 4032 is arranged on the horizontal moving assembly 4033 and is indirectly arranged on the mounting bracket 4031. For example, the horizontal moving assembly 4033 can be any one of a lead screw nut, a slide rail mechanism, a gear and rack, and a chain wheel and chain mechanism. Of course, the longitudinal moving assembly 4032 described above can also be a lead screw nut structure, and the longitudinal driving member is used to drive the lead screw to rotate about its own axis, and the axis of the lead screw is parallel to the first direction Z, and the horizontal moving assembly 4033 is connected to the bottom end of the lead screw. It can be understood that the horizontal moving assembly 4033 comprises a driving member, a driving member and a driven member, the driving member is in transmission connection with the driven member through the driving member, so as to drive the driven member to move along the second direction X, and the driven member is fixedly connected with the bottom end of the lead screw or the guide rail.

[0056] The specific implementation mode of the posture adjusting structure is not limited in the present application, as long as it can realize the adjustment of the position and posture of the cabin door. For example, the posture adjusting structure can also be a six-degree-of-freedom robot purchased, and the cabin door is fixed to the execution end of the six-degree-of-freedom robot through the connecting assembly. The base of the six-degree-of-freedom robot is fixed on the base 10.

[0057] In combination with Figure 2 and Figure 5The spraying module 20 comprises a vertical adjusting assembly 203 connected with the posture adjusting module 40 or the base 10, for example, the vertical adjusting assembly 203 is arranged on the driven part of the horizontal moving assembly 4033 in the above technical solution, or the vertical adjusting assembly 203 is arranged on the pitch driving part 4022 in the above technical solution, or the vertical adjusting assembly 203 is directly installed on the base 10. The spraying support 201 is connected with the vertical adjusting assembly 203 and moves along the first direction Z under the action of the vertical adjusting assembly 203, the spraying support 201 is annular, the spraying pipeline is a flexible pipeline and is contained in the hollow spraying support 201, each spray head 202 is communicated with the flexible pipeline, the spraying support 201 can move along the first direction Z through the vertical adjusting assembly 203, the height of the spraying support 201 is adjusted as needed, which helps to ensure the coverage of the spraying. The spraying pipeline is a flexible pipeline, which can be bent and adjusted as needed, is convenient to be installed in the spraying support 201, and then realizes the mechanical protection of the flexible spraying pipeline through the spraying support 201, and realizes the fixation and support of the flexible spraying pipeline, so that the flexible spraying pipeline can be arranged in a ring shape, and the spraying area or the spraying area of the test piece 100 is ensured.

[0058] For example, the vertical adjusting assembly 203 is connected with the posture adjusting module 40 or the base 10 through the first adapter 204, the vertical adjusting assembly 203 comprises a vertical plate, the spraying support 201 is fixedly connected with the vertical plate through a fastening screw, a plurality of connecting threaded holes 2031 are arranged on the vertical plate and are spaced apart along the first direction Z, and the fastening screw can be connected with any connecting threaded hole on the vertical plate to realize the position adjustment of the spraying support 201 in the first direction Z. Alternatively, the vertical adjusting assembly 203 is a screw nut or a gear and rack mechanism.

[0059] It should be noted that for the embodiment that the vertical adjusting assembly 203 is arranged on the driven part of the horizontal moving assembly 4033 in the above technical solution, the spraying support 201 is connected with the vertical adjusting assembly 203. In other words, the spraying support 201 can rotate synchronously with the test piece 100 under the driving of the pitch adjusting module 402, and can move along the second direction X with the driven part of the horizontal moving assembly 4033. That is, the posture adjusting module 40 is used for synchronously adjusting the posture of the spraying module 20 and the test piece 100, and the spraying module 20 and the test piece 100 remain relatively static during the adjustment of the posture adjusting module 40. At the same time, when the test piece 100 is adjusted to any spraying position by the posture adjusting module 40, the position of the spraying support 201 in the first direction Z can be finely adjusted by the vertical adjusting assembly 203 of the spraying module 20, and the position of the spraying support 201 in the second direction X can be finely adjusted by adjusting the installation position of the first adapter 204 in the second direction X.

[0060] In order to ensure that the spraying module 20 realizes uniform spraying, when the spraying module 20 matches the position of the test piece 100, the spraying support 201 covers the edge position of the test piece 100, and the spraying direction of each spray head 202 is perpendicular to the test piece 100 at the corresponding position, which helps to ensure that each part of the test piece 100 can receive uniform spraying, avoids missing any area of the test piece 100, and the perpendicularity of the spraying direction can ensure that the spraying water directly hits the surface of the test piece 100, ensuring that the spraying water has strong spraying intensity. At this time, if the sealing performance of the test piece 100 is weak, the spraying water will leak to the other side of the test piece 100, which can improve the test accuracy of the rain test.

[0061] Based on the above embodiment, each spray head 202 is in communication with the spraying pipeline through a respective water supply branch pipe, and an adjusting valve and a flow meter are arranged on each water supply branch pipe. Thus, the flow of water in each water supply branch pipe can be obtained through the flow meter. If the flow of water in a water supply branch pipe is inconsistent with the preset flow value, the adjusting valve on the water supply branch pipe can be adjusted to make the flow of water in the water supply branch pipe close to the preset flow value, thereby ensuring the uniformity of spraying of the spraying module 20.

[0062] In order to ensure that the spraying direction of each spray head 202 is perpendicular to the test piece 100 at the corresponding position, each spray head 202 is rotationally connected to the corresponding water supply branch pipe through a corresponding turning connecting piece to adjust the spraying direction.

[0063] Referring to Figure 2 and Figure 6 , the water return assembly 302 further includes a water storage tank 3021, a water return pipeline 3022, a first water pump 3023, a water supply pipeline 3024, and a second water pump. The water storage tank 3021 is fixed on the base 10 through a second support 303, the water return pipeline 3022 is in communication with the water collecting tank 301 and the water storage tank 3021, the first water pump 3023 is arranged on the water return pipeline 3022 and located at the bottom of the water collecting tank 301, the water supply pipeline 3024 is in communication with the spraying pipeline to supply water to the spraying pipeline, and the second water pump is arranged on the water supply pipeline 3024. The first water pump 3023 and the second water pump can extract and lift liquid from a low place to a high place, overcome gravity and terrain difference, and maintain the circulation flow of the liquid. The water storage tank 3021 can balance the water pressure in the water supply pipeline 3024 and maintain the stable water pressure in the water supply pipeline 3024. Alternatively, the height of the second support 303 can be increased so that the lowest position of the water storage tank 3021 is higher than the highest position of the spraying pipeline. At this time, the second water pump is not required to be arranged on the water supply pipeline 3024, and the water in the water storage tank 3021 can directly enter the spraying pipeline through the water supply pipeline 3024.

[0064] The water supply pipeline 3024 and the spray pipeline can be fluidly connected through a hose. The spray support 201 is provided with a through hole, so that the end of the spray pipeline can pass through the spray support 201 and be fluidly connected with the water supply pipeline 3024. In order to ensure that the spray water on the base 10 can be smoothly collected in the water collecting tank 301, a plurality of flow guide through holes penetrating in the first direction Z are formed in the base 10, so as to smoothly guide the water above the base 10 to the water collecting tank 301 below the base 10, and prevent water accumulation above the base 10. In the second direction X, the water return assembly 302 is arranged opposite to the position of the pitch adjusting module 402, so as to avoid the interference between the movement track of the test piece 100 and the water return assembly 302 when the pitch adjusting module 402 adjusts the position of the test piece 100.

[0065] In order to ensure that the water collected in the collecting member 501 can be smoothly discharged from the drain port 5011 thereof and measured by the measuring assembly in the measuring module 50, the distance between the collecting member 501 and the side wall of the test piece 100 facing the collecting member 501 gradually increases from the edge of the collecting member 501 to the drain port 5011. It can also be understood that when the attitude adjusting module 40 adjusts the attitude of the test piece 100 to make the collecting member 501 close to the base 10 relative to the test piece 100, the distance between the collecting member 501 and the base 10 gradually decreases from the edge of the collecting member 501 to the drain port 5011 thereof, so as to ensure that the position of the drain port 5011 is the lowest.

[0066] It should be noted that the pitch adjusting module 402 is also used to repeatedly shake the test piece 100, so as to shake off the water droplets on the wall of the test piece 100, and then the pitch adjusting module 402 is used to rotate the test piece 100 by an angle to adjust the test piece 100 to be substantially horizontal, so as to ensure that the position of the drain port 5011 of the collecting member 501 is the lowest, thereby facilitating the collection of the leakage water.

[0067] The distance between the collecting member 501 and the side wall of the test piece 100 facing the collecting member 501 gradually increases from the edge of the collecting member 501 to the drain port 5011 thereof, which can be achieved by gradually reducing the thickness of the plate-shaped collecting member 501 from the edge thereof to the drain port 5011 thereof, or the collecting member 501 has a hollow conical structure, the drain port 5011 is located at the small end of the conical structure, and the large end of the conical structure is sealingly connected with the edge of the hatch.

[0068] For example, as shown in Figure 7 The test module includes the test piece 100, the second adapter 200 and the state indicator. The second adapter 200 is used to connect the test piece 100 and the collecting member 501, and is also used to achieve the mechanical connection between the test piece 100 and the horizontal moving assembly 4033.

[0069] Referring to Figure 8 The application also provides a control method of the rain test device. The control method is applied to the rain test device according to any one of the technical solutions, and includes an adjusting step, a starting rain step, a closing rain step, and a measuring step. The adjusting step adjusts the posture of the test piece 100 to match the position of the spray head 202 of the spray module 20. The starting rain step includes starting the rain test of the test piece 100 by the spray module 20 and controlling the water return assembly 302 in the water return module 30 to be on to deliver the water in the water collecting tank 301 to the spray pipeline. The closing rain step includes turning off the spray pipeline and the water return module 30. The measuring step includes adjusting the posture of the test piece 100 to make the collecting piece 501 close to the base 10 relative to the test piece 100 to collect the leakage water of the test piece 100, discharging the leakage water through the drain 5011, and measuring the amount of the water discharged through the drain 5011 to obtain the leakage water amount information of the test piece 100.

[0070] In specific use, the position or posture of the test piece 100 is first adjusted by the adjusting step to match the position of the spray module 20, so as to ensure that the water sprayed by the spray head 202 in the spray module 20 can be accurately sprayed on the test piece 100 to test the sealing performance and drainage performance of the test piece 100. When the spray water is sprayed on the test piece 100, the water flows downward along the test piece 100 under the action of gravity and is then collected in the water collecting tank 301 of the water return module 30, and then is re-delivered to the spray pipeline by the water return assembly 302 and sprayed out through the spray head 202, so as to realize the recycling of the spray water. After the spray module runs for a period of time, it is confirmed that the rain test is completed, the spray pipeline is then cut off to stop the spray head 202 from continuing to spray water, and the posture adjusting module 40 adjusts the posture of the test piece 100 to rotate the test piece 100 by an angle, so that the collecting piece 501 is close to the base 10 relative to the test piece 100, i.e., the collecting piece 501 is located below the test piece 100. If the sealing performance of the test piece 100 is poor, a part of the water will leak from one side of the test piece 100 to the other side of the test piece 100, and then be collected in the collecting piece 501. Subsequently, the leakage water amount information of the leakage water is measured by the measuring assembly, so as to realize the automatic rain test of the test piece 100 and the accurate measurement of the leakage water amount information of the leakage water.

[0071] Based on the above embodiment, before the adjustment step, the method further includes: applying a wet / dry indicator to the side of the test piece 100 facing the collecting member 501, and then connecting the collecting member 501 to the side of the test piece 100 facing away from the spray module 20. Furthermore, after starting the rain shower step and before stopping the rain shower step, the method further includes: collecting real-time image information of the side of the test piece 100 facing the collecting member 501, and confirming the leakage location and time of the test piece 100 based on the image information. The collected image information can capture subtle leakage locations and changes, helping to accurately locate the leakage point and improve detection accuracy. Furthermore, the collected image information can be processed and analyzed to determine the leakage location and time of leakage, making the monitoring results more intuitive and visual, and facilitating analysis and judgment by operators.

[0072] In order to ensure that the water pressure of each nozzle 202 is consistent and the spraying uniformity of the spray module 20 in the rain test is guaranteed, Figure 9 As shown, after the step of starting the spray module 20 to perform a rain test on the test piece 100, it also includes: collecting flow information of water in the water supply branch pipe, wherein the water supply branch pipe connects the nozzle 202 and the spray pipe; judging whether the flow information meets the flow value corresponding to the rain test working condition; if not, adjusting the flow of water in the water supply branch pipe, and returning to the step of collecting the flow information of water in the water supply branch pipe; if satisfied, monitoring the rain duration of the test piece 100, and when the rain duration reaches a preset duration, determining that the rain test is over and executing the step of closing the rain.

[0073] In some embodiments of the present application, the adjustment step also includes: adjusting the height of the spray bracket 201 and adjusting the angle of the nozzle 202 so that the spray direction of the nozzle 202 is perpendicular to the test piece 100 at the corresponding position, ensuring that the spray water is sprayed to the test piece 100 with maximum pressure to improve the detection accuracy.
