Detailed Description
The following combines the drawings of the utility model to further elaborate the technical scheme and technical effect of the utility model.
Referring to fig. 1 and 2, in one embodiment, a static water area stratified sampling device 10 is used for obtaining water quality samples of static water areas, such as lakes and pools, and facilitating water quality monitoring of the static water areas. The static stratified water sampling apparatus 10 includes: the layered sampling tube 100 is hollow and has two open ends, an upper cover body 200 and a lower cover body assembly 300. The upper cover 200 can cover the upper end of the layered sampling tube 100. Lower cover body assembly 300 includes fixed clamp 310, lower cover body drive connecting rod 320 and lower cover body 330, the one end of fixed clamp 310 is fixed in on the layering sampling tube 100, lower cover body drive connecting rod 320 rotatable coupling in the other end of fixed clamp 310, the side of lower cover body 330 is provided with connection handle 331, connect handle 331 connect in the lower extreme of lower cover body drive connecting rod 320, lower cover body drive connecting rod 320 rotates, drives lower cover body 330 winds lower cover body drive connecting rod 320 rotates, lower cover body 330 can the lid fit the lower extreme of layering sampling tube 100.
Specifically, the layered sampling tube 100 is a hollow tube body with a length of 1.0m to 1.5m, two ends of the hollow tube body are open, and the upper cover body 200 can be covered above the layered sampling tube 100 in a screwing mode, an inserting mode, a riveting mode, a clamping mode and the like, so that the upper end of the layered sampling tube 100 is sealed. The upper surface of the lower cap 330 is flush with or slightly lower than the lower end of the layered sampling tube 100, the lower cap 330 can be close to or away from the lower end of the layered sampling tube 100 under the action of the lower cap driving link 320, when the lower cap 330 is close to the lower end of the layered sampling tube 100, the lower end of the layered sampling tube 100 is sealed, and when the lower cap 330 is far away from the lower end of the layered sampling tube 100, the lower end of the layered sampling tube 100 is opened. Further, in order to enhance the sealing performance between the lower cover 330 and the lower end of the layered sampling tube 100, a sealing gasket 110 is disposed at the lower end of the layered sampling tube 100, and a sealing gasket 332 is disposed at the upper end of the lower cover 330. In one embodiment, an operating handle 340 is disposed at an upper end of the lower cover driving link 320, so that the lower cover driving link 320 can be rotated by the operating handle 340.
When a static water area is sampled hierarchically, the upper cover 200 and the lower cover 330 are opened at the same time, and the lower end of the layered sampling tube 100 is immersed in the water area to be sampled and extends to a predetermined sampling position, and the upper end of the layered sampling tube is exposed to the air. After the sample is kept still for a period of time, the upper cover 200 is closed, and the lower cover driving link 320 is rotated, so that the lower cover 330 is closed to the lower end of the layered sampling tube 100, thereby preventing the reference height of the sample from changing.
