In addition, in the preferred embodiment of utility model, also be provided with surplus valve 7 in the outdoor rainwater vasculum 6, be used to get rid of unnecessary rainwater.Rainwater storage bin 5 also is provided with water level limit switch 9, and the porch of water pipe 14 is provided with this water level limit switch 9, and water pipe 14 is connected rainwater storage bin 5 and rainwater towards drenching storage bin 12.
Embodiment as shown in Figure 1, its principle of work is:
1, carries out the rainwater collection through outdoor rainwater vasculum 6, and guarantee that the water yield is sufficient in the rainwater storage bin 5;
2, energized, and the output water yield of setting flow controller (per hour/millimeter) and regularly, and the angle of adjustment test specimen fixed mount;
3, test block is fixed to the test specimen frame, the turn-on flow rate controller switches;
4, in the test process,, reach the effect of natural precipitation, check after treating regularly to finish that model receives the situation of rain erosion (aberration and gloss change) through the output water yield of flow controller 3.
The flow controller setup parameter:
(precipitation rate: per hour/millimeter)
Light rain=per hour/＜10 millimeter
Moderate rain=per hour/the 10-24.9 millimeter
Heavy rain=per hour/the 25-49.9 millimeter
Heavy rain=per hour/the 50-100 millimeter
Extra torrential rain=per hour/＞100 millimeter
Discrimination method:
Aberration: on two identical test sample plate, the position measurement of 3 same vertical in upper, middle and lower is averaged respectively.Regulation by GB/T9761 is carried out colorimetric with test sample plate and standard jig.The change color degree is graded before and after pressing film aging.
Grade is following:

| 1 | Light discolouration slightly | 1.6～3.0 |
| 2 | Light discolouration | 3.1～6.0 |
| 3 | Obviously variable color | 6.1～9.0 |
| 4 | Big variable color | 9.1～12.0 |
| 5 | Serious discoloration | ＞12.0 |
Gloss: the gloss intensity of variation before and after the test of range estimation paint film.Press the gloss that GB/T9754 measures the test front and back, on two identical test sample plate, the position measurement of 3 same vertical in upper, middle and lower is averaged respectively.Relatively calculate the loss of gloss rate in the back with standard jig.
Grade is following:
Applicating example one: different sample contrasts
1, prepares each two on the model of two different samples respectively, and put at test specimen fixed mount center position, carry out rainwater under the same conditions and dash the situation of drenching to guarantee to test;
2, the output water yield of flow controller being arranged to heavy rain (per hour/25-49.9 millimeter) time set is 1 hour, and guarantees that flow controller can normally export the water yield, and test specimen has been fixed on the test specimen frame;
3, energized, the switch of turn-on flow rate controller;
4, model is checked in contrast after whole the completion;
5, the result judges:
The output water yield through flow controller is arranged under the situation of heavy rain (per hour/25-49.9 millimeter), in inventor's test:
Sample A has slight variable color.And sample B is under same condition, the situation of no variable color.The test result of color difference meter is consistent with above-mentioned conclusion, and the scope of sample A value of chromatism is between 3.1～6.0, and sample B then＜＜1.5;
Sample A has slight loss of gloss, and sample B loss of gloss is not obvious.Glossometer test result basically identical, sample A loss of gloss rate are between 16～30%, and sample B loss of gloss rate is between 4～15%;
From above judgement, sample A is obviously not as sample B to the performance of rain erosion resistant;
Applicating example two: different precipitation amount contrast
1, prepares ten pieces of model of same product respectively, and two are put at test specimen fixed mount center position, carry out rainwater under the same conditions and dash the situation of drenching to guarantee to test;
2, the output water yield of flow controller being arranged to light rain (per hour/＜10 millimeter) time set is 1 hour, and guarantees that flow controller can normally export the water yield, and test specimen has been fixed on the test specimen frame;
3, energized, the switch of turn-on flow rate controller;
4, the output water yield of flow controller is arranged to moderate rain (per hour/10-24.9 millimeter), heavy rain (per hour/25-49.9 millimeter), heavy rain (per hour/50-100 millimeter), extra torrential rain (per hour/＞100 millimeter); The time setting is 1 hour; By each two principle; All the other eight are tested, and all the other steps are identical;
5, treating all to accomplish the back contrasts and checks model;
The result judges;
The output water yield through the current control instrument is provided with respectively under 5 kinds of simulation rainwater situation to light rain (per hour/＜10 millimeter), moderate rain (per hour/10-24.9 millimeter), heavy rain (per hour/25-49.9 millimeter), heavy rain (per hour/50-100 millimeter), extra torrential rain (per hour/＞100 millimeter), tests 1 hour;
This time specimen is under the situation of light rain (per hour/＜10 millimeter); Basically the situation of not having variable color; But serious all the more from moderate rain (per hour/10-24.9 millimeter) beginning, heavy rain (per hour/50-100 millimeter) and extra torrential rain (per hour/＞100 millimeter) are more or less the same.The test result of color difference meter and above-mentioned conclusion basically identical, trend is the same.
Gloss and The above results basically identical, trend is the same.Sample is under light rain (per hour/＜10 millimeter) situation, and gloss does not have the loss of gloss phenomenon basically, surpasses then to begin that loss of gloss is arranged, and along with the setting of quantity of precipitation is big more, the loss of gloss phenomenon is obvious more.
From above judgement, this sample can only bear the rain erosion of light rain (per hour/＜10 millimeter).The scope that surpasses light rain can cause the phenomenon of serious discoloration and loss of gloss, needs to improve sample.
Applicating example three: different contrast towards the pouring time
1, prepares ten pieces of model of same product respectively, and two are put at test specimen fixed mount center position, to guarantee to test under the same conditions rainwater towards the pouring situation;
2, the output water yield of flow controller being arranged to moderate rain (per hour/10-24.9 millimeter) time set is 1 hour, and guarantees that flow controller can normally export the water yield, and test specimen has been fixed on the test specimen frame;
3, energized, the switch of turn-on flow rate controller;
4, the output water yield of flow controller is arranged to moderate rain (per hour/10-24.9 millimeter), time and is provided with respectively and is 3,5,5,10 hours, by every each time principle of two, all the other eight are tested, step is identical;
5, treating all to accomplish the back contrasts and checks model;
6, the result judges;
The output water yield through flow controller is arranged under the situation of moderate rain (per hour/10-24.9 millimeter), contrasts 1,3,5,7,10 5 time period test respectively;
This time specimen is arranged in the output water yield of flow controller under the situation of moderate rain (per hour/10-24.9 millimeter), the situation of no variable color in 1,3 hour, but began just to have the situation of variable color in 5 hours, 10 hours are the most serious.The test result of color difference meter is consistent with above-mentioned conclusion, and trend is the same;
Gloss and The above results basically identical, trend is the same.Sample is in 3 hours, and gloss does not have the loss of gloss phenomenon basically, surpasses 3 hours and then begins to have loss of gloss, and along with the increase towards the pouring time, the loss of gloss phenomenon is obvious more;
From above judgement, this sample can only bear 3 hours under the situation of moderate rain (per hour/10-24.9 millimeter) rain erosion, surpassed the phenomenon that then had obvious variable color and loss of gloss in 3 hours, needed to improve sample;
Therefore, utilize the utility model can realize the fast and convenient rain erosion performance of judging decorations coating, and relevant reference frame can be provided, realized the original intention of the utility model.
