Operation principle and process
When downward putting device samples：The first drawstring 1 and the second drawstring 2 are transferred, device is entered water-bed arrival mud, makes branch
Spike 22 is put on mud.The second drawstring 2 is pulled, screw mandrel 8 is up moved, because the sliding block 9 at the both ends of screw mandrel 8 positions in side
Slided in the guide rail of plate 10, positioning screw rod 8 is vertically movable.Because screw mandrel 8 is connected by the first bolt 11 with the first scissor 12, silk
The upward motion of bar 8 drives the first scissor 11 to move up, and now overcomes the elastic force of spring 15.Due to the connection of the second bolt 13, make
Obtain the increase of the first scissor 11 and the angle of the second scissor 12 so that by the first closed plate 17, the second closed plate 18, the 3rd closed plate
The scraper bowl of 19 compositions is closed, because the bottom of support feet 22 navigates to mud, so can be sampled to mud when scraper bowl closes.By
In making whole device be in plateau at work, support feet 22 can overcome mud landforms are uneven to influence, also not by current
Influence it is dirty in the Study of Environmental Changes and environment to the shallow-layer such as lake or reservoir waters so that the sample quality obtained is high
Played 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.
3rd, after obtaining sample：Make after being moved up due to the first scissor 11 in the case of spring 15 is in elongation, thus removing the second drawstring
After 2 pulling force, spring 15 recovers deformation so that scraper bowl automatically opens up, and realizes opening type self-locking, convenient to use next time.
