Operation principle and process
When downward putting device samples：The first drawstring 1 and the second drawstring 2 are transferred, so that device is entered water-bed arrival mud, makes branch
Spike 22 is put on mud.The second drawstring 2 is pulled, lead screw 8 is made up to move, since the sliding block 9 at 8 both ends of lead screw is positioned in side
Sliding, 8 vertical and straight movement of positioning screw rod in the guide rail of plate 10.Since lead screw 8 is connected by the first bolt 11 with the first scissor 12, silk
Moving upwards for bar 8 drives the first scissor 11 to move up, and overcomes the elastic force of spring 15 at this time.Due to the connection of the second bolt 13, make
Obtain the increase of 12 angle of the first scissor 11 and the second scissor so that by the first closed plate 17, the second closed plate 18, third closed plate
The scraper bowl of 19 compositions is closed, since 22 bottom of support leg navigates to mud, so can be sampled to mud when scraper bowl is closed.By
In making whole device be in plateau at work, support leg 22 can overcome mud landforms injustice to influence, also not by flow
Influence, it is dirty in the Study of Environmental Changes and environment to the shallow-layers such as lake or reservoir waters to keep the sample quality of acquirement high
It plays an important role in dye detection.
When sampling terminates to obtain sample：The first drawstring 1 and the second drawstring 2 are pulled up so that device leaves the water surface, acquisition sample.
Third, after obtaining sample：In the case of so that spring 15 is in elongation after being moved up due to the first scissor 11, thus removing the second drawstring
After 2 pulling force, spring 15 restores deformation so that scraper bowl automatically opens, and realizes opening type self-locking, convenient to use next time.
