[0024] The mounting ring 801 is put on the outside of the enclosure 1. When the top of the enclosure 1 contacts the inner wall of the filter plate 802, the position of the filter plate 802 will be blocked. When it rains outside, the rainwater first falls on the top of the filter plate 802, and the rainwater and impurities therein will slide down along the slope of the filter plate 802. During this period, the rainwater will gradually pass through the holes of the filter plate 802 and fall into the inside of the enclosure 1. The impurities will be driven by the rainwater to slide to the outside, thereby continuously collecting rainwater. When the rainwater falls into the space formed by the enclosure 1 and the closing part 4, some fine particles will be concentrated at the bottom along the slope of the closing part 4, preventing these impurities from mixing into the rainwater sample during the discharge process and affecting subsequent detection work.

[0032] The utility model provides a sampling device for analyzing and detecting roof rainwater. The specific working principle is as follows:

[0033] When the device is working, the mounting ring 801 is first placed on the outside of the enclosure 1. When the top of the enclosure 1 contacts the inner wall of the filter plate 802, the position of the filter plate 802 will be blocked. When it rains outside, the rainwater first falls on the top of the filter plate 802, and the rainwater and the impurities therein will slide down along the slope of the filter plate 802. During this period, the rainwater will gradually pass through the holes in the filter plate 802 and fall into the inside of the enclosure 1. The impurities will be driven by the rainwater to slide to the outside, thereby continuously collecting rainwater. When the rainwater falls into the space formed by the enclosure 1 and the closing part 4, some fine particles will be concentrated at the bottom along the slope of the closing part 4 to prevent these impurities from mixing into the rainwater sample during the discharge process and affecting subsequent detection work. Water only needs to be discharged from the outlet 6 to ensure that only the rainwater in the middle will be discharged.
