Embodiment 1
[0034] Embodiment 1: In order to achieve the purpose of sampling sewage at different depths and improving the accuracy of the sampling process, this embodiment provides a sampling device for water pollution detection, see Figure 1-4Specifically, it includes a bottom plate 1, an engaging mechanism, a lifting mechanism, a sliding mechanism, and a sampling assembly. The bottom plate 1 is a rectangular plate placed horizontally and horizontally. A bearing groove is opened on the right side of the top surface of the bottom plate 1, and a bearing is installed in the bearing groove. The vertical cylinder 2 is inserted into the bearing, and the vertical cylinder 2 is connected with the bottom plate 1 through an engaging mechanism. The vertical cylinder 2 is inserted with an inner cylinder 23 that slides through, and the inner cylinder 23 is connected with the vertical cylinder 2 through a lifting mechanism; the inner cylinder 23 The top is provided with a horizontally fixed rectangula...
Embodiment 2
[0039] Embodiment 2: In Embodiment 1, there is also the problem that the sampling assembly does not extend to the middle of the river surface. Therefore, on the basis of Embodiment 1, this embodiment also includes:
[0040] In the present invention, the sliding mechanism includes a rack 33, a sliding motor 34, and a gear 35. The top surface of the rectangular long plate 32 is provided with a horizontally fixed rack 33, and the left side of the top surface of the rectangular long tube 3 is provided with a limiting hole. A sliding motor 34 is installed on the left side of the top surface of the rectangular long tube 3. The model of the sliding motor 34 is TYBZ-300-100L-4, and a coaxially connected gear 35 is arranged at the end of the motor shaft of the sliding motor 34 in the limit hole. , and the gear 35 is meshed with the rack 33, and the rectangular long tube 3 is provided with a slidingly connected rectangular slider 31, the rectangular slider 31 is fixedly connected to the ...
Embodiment 3
[0041] Embodiment three: see Figure 5 , in the present embodiment, the present invention also proposes a sampling method of a sampling device for water pollution detection, comprising the following steps:
[0042] Step 1, push the roller 11 to move the bottom plate 1 to the riverside position in the water pollution area, and each component is electrically connected to the external power supply through the power line;
[0043] Step 2, start the meshing motor 15, control the motor shaft of the meshing motor 15 to drive the bevel gear 16 to rotate synchronously, the meshing drives the bevel gear ring 18 and the fixed ring 17 to rotate, drives the vertical cylinder 2 and the inner cylinder 23 to rotate 180°, and then drives the rectangular long The cylinder 3 and the fixed plate 4 rotate 180°, which drives the L-shaped plate 42 to move above the river, and stops the operation of the meshing motor 15;
[0044] Step 3, start the sliding motor 34, control the motor shaft of the sli...
