[0046] The cabinet 100 is in a rectangular shape, with a height of 1175mm, a length of 1400mm, and a width of 500mm. It is welded from a square tube and a flat plate made of stainless steel, and has a door panel with sealing rings around it. A leveling mechanism is provided at the bottom of the cabinet 100, and the leveling mechanism includes support columns and support bolts connected to the four corners of the bottom of the cabinet 100. The cabinet 100 is placed horizontally by adjusting the matching length of the support bolts and the support columns. A step is provided inside the cabinet 100 to support the water collection assembly 500, and the step is made of PVC board.

[0047] The collecting tray 200 is used to collect rainwater flowing in from the opening; the outer edges of the collecting tray 200 are sealed and connected to the inner wall of the cabinet 100. The collecting tray 200 is tilted, and the distance between the high position of the collecting tray 200 and the top of the cabinet 100 is 120 mm, and the distance between the low position of the collecting tray 200 and the top of the cabinet 100 is 150 mm, so that rainwater can flow into the water inlet pipe 300 easily.

[0048] The input end of the water inlet pipe 300 is connected to the lower position of the collection tray 200. The output end of the drain pipe 400 passes through the bottom of the cabinet 100 and faces the outside of the cabinet 100. The water inlet pipe 300 and the drain pipe 400 are arranged vertically. The water inlet pipe 300 is provided with a first stop valve 310, and the drain pipe 400 is provided with a second stop valve 410. The stop valve can be used to adjust the rainwater flow, and the stop valve produced by Zhejiang Hengxin Pipe Industry Co., Ltd. can be used but is not limited to.

[0049] The water collecting components 500 are arranged between the water inlet pipe 300 and the drainage pipe 400 and there are six of them, and the installation heights of the six water collecting components 500 decrease from top to bottom; the water collecting components 500 have a sampling bottle 510 and a control mechanism for controlling the flow direction of rainwater to switch between flowing to the water inlet of the sampling bottle 510 and flowing to the adjacent downstream water collecting component 500.

[0050] The sampling bottle 510 is provided with a drain valve 511 and an anti-overflow valve 512; the drain valve 511 can facilitate the transfer of rainwater collected in the sampling bottle 510 to an external sample bottle after the use is completed, and send it to the laboratory for water quality testing; the anti-overflow valve 512 can not only connect to the atmosphere to provide atmospheric pressure so that the water sample can smoothly enter the sampling bottle 510, but also prevent the water sample in the sampling bottle 510 from overflowing out of the sampling bottle 510 when the liquid level valve 520 does not work for some reason, and can be but not limited to a one-way float check valve produced by Shanghai Boers Valve Manufacturing Co., Ltd. The volume of the sampling bottle 510 is preferably 1L, so that the collection volume can meet the needs of water quality analysis.

[0051] In this embodiment, the length of the collection plate 200 is 1040 mm and the width is 400 mm. There are 6 sampling bottles 510. The total volume of the 6 sampling bottles 510 is 6L, which can cover the entire rainfall process with a rainfall amount within 15 mm. The rainfall collected by a single sampling bottle 100 is 2.5 mm.

[0052] The control mechanism includes a liquid level valve 520 and a water delivery pipeline. The liquid level valve 520 is used to control the opening and closing of the water inlet of the sampling bottle 510. The liquid level valve 520 can be, but is not limited to, a 4-point pressureless valve produced by Wenzhou Chenglin Technology Co., Ltd.; the water delivery pipeline is used to transport rainwater flowing between the water inlet pipe 300 and the drain pipe 400. The water delivery pipeline includes a main pipe 531 and a first branch pipe 532 and a second branch pipe 533 arranged at the output end of the main pipe 531; the input end of the second branch pipe 533 is higher than the input end of the first branch pipe 532; the input end of the main pipe 531 is connected to the output end of the second branch pipe 533 of the water inlet pipe 300 or the adjacent upstream water collection component 500; the output end of the first branch pipe 532 is connected to the water inlet of the sampling bottle 510; the output end of the second branch pipe 533 is connected to the drain pipe 400 or the main pipe 531 of the adjacent downstream water collection component 500. Therefore, since the input end of the second branch pipe 533 is higher than the input end of the first branch pipe 532, the rainwater first flows into the first branch pipe 532 and is then collected by the sampling bottle 510. When the rainwater in the sampling bottle 510 reaches the required volume, the rainwater collection for the current period is completed, and then the liquid level valve 520 is automatically closed. The rainwater will gradually overflow into the second branch pipe 533 and then flow to the downstream sampling bottle 510 to collect rainwater for the next period.

[0053] The main pipe 531, the first branch pipe 532 and the second branch pipe 533 are arranged horizontally, and the output end of the main pipe 531 is connected to the input end of the first branch pipe 532 and the second branch pipe 533 by a Y-type three-way valve 534. The water inlet pipe 300 and the main pipe 531 and the drain pipe 400 and the second branch pipe 533 are connected by a 90° elbow. The output end of the first branch pipe 532 is connected to the water inlet of the sampling bottle 510 by a 90° elbow and a first vertical pipe 610, and the second branch pipe 533 is connected to the main pipe 531 of the adjacent downstream water collection component 500 by a 90° elbow and a second vertical pipe 620. As a result, the flow pipe of rainwater can be quickly disassembled and assembled on site, which is very convenient to use.

[0055] Figure 3 Schematic diagram of the structure of the rainwater collector of this embodiment.

[0056] Compared with the first embodiment, the rainwater collector of the present embodiment has the following differences: Figure 3 As shown, the rainwater collector includes two water collection units 700, each of which has three water collection components 500, and the height change directions of the water collection components 500 in the two water collection units 700 are opposite. Therefore, the internal space of the cabinet 100 can be fully utilized, the length of the cabinet 100 is reduced to 700mm, and the area occupied by the rainwater collector is significantly reduced.

[0057] In this embodiment, the length of the collection plate 200 is 520 mm and the width is 400 mm. There are 6 sampling bottles 510, and the total volume of the 6 sampling bottles 510 is 6L, which can cover the entire rainfall process with a rainfall amount within 30 mm. A single sampling bottle 100 collects 5 mm of rainfall.

[0058] Example 3

[0059] Figure 4 Schematic diagram of the structure of the rainwater collector of this embodiment.

[0060] Compared with the second embodiment, the rainwater collector of the present embodiment has the following differences: Figure 4 As shown, the output end of the second branch pipe 533 of the upstream water collection unit 700 is provided with a T-type three-way valve 800, the vertical downward connection port of the T-type three-way valve 800 is connected to the main pipe 531 of the downstream water collection unit 700 through the third vertical pipe 630 and the 90° elbow, and the vertical upward connection port of the T-type three-way valve 800 is connected to the fourth vertical pipe 640, and the upper end outlet of the fourth vertical pipe 640 is higher than the input end height of the water inlet pipe 300 (shown by the dotted line in the figure). Therefore, by providing the fourth vertical pipe 640, by making the upper end outlet of the fourth vertical pipe 640 connected to the atmospheric pressure and higher than the input end height of the water inlet pipe 300, it is possible to prevent the overflow of water flow in the case of a full pipe.

[0061] The embodiment of the rainwater collection method of the utility model adopts the rainwater collector described in any one of the above embodiments.

[0062] The above is an explanation of the relevant contents of the utility model. A person skilled in the art will be able to implement the utility model based on these explanations.
