[0018] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model. On the contrary, the embodiments of the present utility model include all variations, modifications and equivalents that fall within the spirit and scope of the appended claims.

[0019] The rain detection device according to the embodiments of the present utility model will be described below with reference to the drawings.

[0020] As Figure 1 shown, the rain detection device according to the embodiments of the present utility model may include a collection box 4, a sliding rod 1, a plurality of support rods 2, a driving mechanism 3, a connection mechanism 5, a sliding plate mechanism 6, a plurality of partition plates 7, a plurality of rain inlets 8, a plurality of test papers 9, and a bottom box 10.

[0021] Among them, the sliding plate mechanism 6 is arranged on the collection box 4, and a plurality of partition plates 7 are arranged inside the collection box 4.

[0022] It should be noted that in this embodiment, the provided partition plates 7 divide the interior of the collection box 4 into different cavities, which are mainly used to distinguish the rainwater collected at different times.

[0023] The sliding rod 1 is installed on one side of the driving mechanism 3. A strip groove 11 is provided on the sliding rod 1. A plurality of support rods 2 are installed on the collection box 4, and the support rods 2 are arranged at the bottom of the driving mechanism 3 and the sliding rod 1.

[0024] It should be noted that the provided strip groove 11 enables the support assembly 52 to move on the strip groove 11, and the provided support rods 2 are used to support the sliding rod 1.

[0025] The connection mechanism 5 may include a linkage assembly 51 and a support assembly 52.

[0026] Among them, one end of the linkage assembly 51 is connected to the support assembly 52, the other end of the linkage assembly 51 is connected to the driving mechanism 3, and the support assembly 52 is installed on the sliding plate mechanism 6.

[0027] It can be understood that the linkage assembly 51 can drive the support assembly 52 to move on the sliding rod 1. At the same time, a strip block (not shown in the figure) that matches the strip groove 11 is provided on the support assembly 52, which enables the support assembly 52 to slide on the sliding rod 1.

[0028] The bottom box 10 is arranged at the bottom of the collection box 4, the rain inlets 8 are arranged between the collection box 4 and the bottom box 10, and a plurality of test papers 9 are arranged on the bottom box 10.

[0029] It should be noted that the rain inlet 8 described in this embodiment can transfer rainwater from the collection box 4 to the bottom box 10, and a switch valve can be arranged on the rain inlet 8 to control the transfer of rainwater. At the same time, the test paper 9 can be a pH (potential of hydrogen) test paper, which is used to test the acidity and alkalinity of rainwater, so as to test the pollution degree of rainwater.

[0030] Specifically, when it is necessary to detect rainwater, first place the device in an open area on the ground, turn on the rotating motor 32, and when the rotating motor 32 rotates, it will drive the first connecting rod 511 and the second connecting rod 513 to rotate. During the rotation of the second connecting rod 513, the third connecting rod 515 will drive the limiting block to move in the limiting groove 521. Therefore, during the rotation of the rotating motor 32, the support assembly 52 will slide on the surface of the sliding rod 1 through the mutual cooperation of the strip and the strip groove 11.

[0031] Therefore, as the support assembly 52 gradually moves, the support assembly 52 will drive the skateboard mechanism 6 to move on the collection box 4, so that the water drainage groove 611 corresponds to the cavities on different sides of the partition 7, and the rainwater at different times is collected through different cavities. After the collection is completed, by controlling the rain inlet 8, the rainwater is dripped onto the test paper 9, and the color change of the test paper 9 can be observed, so as to test the acidity and alkalinity of the rainwater.

[0032] Thus, rainwater at different times can be collected and detected, and the concentration of pollutants at different stages of rainfall can be obtained, making the detection results more accurate.

[0033] It should be noted that in this embodiment, the rotating motor 32 can be controlled by a remote switch, avoiding outdoor operation.

[0034] In an embodiment of the present utility model, as Figure 2 shown, the support assembly 52 may include the support assembly 52, clamping grooves 522 are arranged on both sides of the support assembly 52, and a limiting groove 521 is formed on the support assembly 52.

[0035] It should be noted that the clamping grooves 522 provided can limit the moving blocks 514 and the limiting blocks 516 on both sides.

[0036] In an embodiment of the present utility model, as Figure 2 shown, the linkage assembly 51 may include a first connecting rod 511, a rotating shaft 512, a second connecting rod 513, a moving block 514, a third connecting rod 515, and a limiting block 516.

[0037] One end of the first connecting rod 511 is connected to the driving mechanism 3, and the rotating shaft 512 is respectively connected to the other end of the first connecting rod 511, one end of the second connecting rod 513, and one end of the third connecting rod 515.

[0038] It should be noted that the third connecting rod 515 can move inside the limiting groove 521 through the rotating shaft 512.

[0039] The moving block 514 is connected to the other end of the second connecting rod 513, and the moving block 514 is arranged on one side of the clamping groove 522. The limiting block 516 is connected to the other end of the third connecting rod 515, and the limiting block 516 matches the limiting groove 521.

[0040] It can be understood that the first connecting rod 511 and the second connecting rod 513 are fixedly connected on the same horizontal line. When they rotate, the third connecting rod 515 rotates inside the limiting groove 521 through the rotating shaft 512.

[0041] In an embodiment of the present invention, as Figure 1 shown, the driving mechanism 3 may include a connecting block 31 and a rotating motor 32.

[0042] Among them, the rotating motor 32 is arranged on the connecting block 31, and the rotating motor 32 is connected to the first connecting rod 511. The output shaft of the rotating motor 32 is connected to the first connecting rod 511 for driving the first connecting rod 511 to rotate.

[0043] In an embodiment of the present invention, as Figure 2 shown, the skateboard mechanism 6 may include a first skateboard 61, a second skateboard 62, and a third skateboard 63.

[0044] Among them, two second skateboards 62 are arranged on both sides of the first skateboard 61, two third skateboards 63 are arranged outside the second skateboards 62, and a water draining groove 611 is formed on the first skateboard 61.

[0045] It should be noted that in this embodiment, the widths of the first skateboard 61, the second skateboard 62, and the third skateboard 63 are the same as the distance between the partition plate 7 (or between the partition plate 7 and the side wall of the collection box 4). During the process of the rotating motor 32 rotating to drive the support assembly 52 to move, the support assembly 52 will move the first skateboard 61 to the top of different cavities to realize the collection of rainwater in different periods. At the same time, no matter when the first skateboard 61 moves to any cavity, the second skateboard 62 and / or the third skateboard 63 on its side can block the remaining cavities to realize the separate collection of rainwater in different periods.

[0046] In summary, the rainwater detection device of the embodiment of the present invention can collect and detect rainwater in different periods, obtain the concentrations of pollutants in different stages of rainfall, and make the detection results more accurate.
