Inconvenient disadvantage is sampled, water sample can be acquired rapidly when water is smaller, improves water quality sampling efficiency in rain sewage network.
Detailed description of the invention
Fig. 1 be the utility model proposes a kind of city rain sewage network deep water water quality sampling device structural schematic diagram.
Specific embodiment
Referring to Fig.1, the utility model proposes a kind of city rain sewage network deep water water quality sampling device, comprising: sampling
Case 1, is equipped with sample storage case 2 in sampling box 1, and sample storage case 2 offers water inlet and gas outlet, sample storage case 2 into
The mouth of a river is equipped with the first valve body, and the gas outlet of sample storage case 2 is equipped with the second valve body, and the gas outlet of sample storage case 2 and negative pressure are sent out
The air inlet of life structure 4 is connected to, and 1 bottom of sampling box offers several through-holes, several water gathering tubes 3, through-hole are provided in sampling box 1
It is corresponded with water gathering tube 3,3 one end of water gathering tube is connected to the water inlet of sample storage case 2, and the other end and through-hole are tightly connected.
When specifically used, water gathering tube 3 can extend into or out through-hole, and the inner wall of the outer wall of water gathering tube 3 and through-hole seals
Connection；It the end of the certain one end of water gathering tube 3 far from sample storage case 2 can also be solid with the sampling box sealed bottom at through-hole edge
