When the collecting head device works, a worker can put the collecting head 1 into a water body to be sampled, and the putting depth of the collecting head 1 is adjusted through the furling device 3. When the collecting head 1 reaches a preset depth area, the sampling device in the embodiment can start water body collection, and the collected water body sample can be retained inside the collecting box 2, so that a worker can analyze the water body sample.
Optionally, in this embodiment, the winding device 3 includes a winding drum and a driving motor, the winding drum is driven by the driving motor, and the collecting tube 21 is wound on the winding drum.
In order to facilitate the sample collection and sample preservation of the device, a collection bottle and a collection pump are arranged inside the collection box 2, the collection pump is communicated with the collection pipe 21, and the collection pump is communicated with the collection bottle. Alternatively, the collection vial may comprise a blank control vial and a plurality of sample collection vials. The blank control bottle is filled with pollution-free purified water and can be used as a blank control item when a water body component analysis experiment is carried out; the sample collecting bottle can be divided according to the collecting depth, so that the distribution rule of pollutants in the water body can be obtained by workers conveniently.
FIGS. 2-4 are schematic views of the pick head 1 of this embodiment, and it can be seen that the pick head 1 comprises: base 4, connecting pipe 5 and inlet 6. The top of the base 4 is provided with a connecting seat 41, a first claw 7 is arranged on the periphery of the connecting seat 41, and a static pressure liquid level meter 71 is arranged inside the first claw 8.
