Through the above technical solutions, water sample enters in acquisition tank from water inlet pipe, adopted after filtration core by outlet pipe Collect, the solid impurity in water sample is retained by filtration core, and the position of filtration core is far from water inlet pipe at this time；After stopping sampling, Xiang Qingxi High pressure water or high pressure gas are passed through in pipe, the solid impurity for passing through filtration core is pressed into filtration core close to the one of water inlet pipe again Side, solid impurity is taken out in the convenient side in filtration core, while filtration core is also pressed to water inlet pipe, cleans the interior of acquisition tank Wall reduces the cleaning difficulty of acquisition tank.

Further, sealing ring is fixedly connected on the periphery that the filtration core is contacted with the acquisition tank.

Through the above technical solutions, sealing ring can allow filtration core to scrape cleaner by the inner wall for acquiring tank.

Further, high-pressure pump or high-pressure water tank are communicated with by check valve in the cleaning pipe.

Through the above technical solutions, check valve can be avoided impurity as style enters high-pressure pump or high-pressure water tank In.

Further, strainer valve is communicated on the outlet pipe.

Through the above technical solutions, strainer valve can again be filtered water sample, the solid impurity in water sample is reduced.

Further, the acquisition tank is removably connected with cleaning lid close to one end of the water inlet pipe.

Through the above technical solutions, disassembly, cleaning lid can facilitate the solid impurity taken out by under filtering.

Further, the filtration core is provided with multiple, and along the length direction arrangement of the acquisition tank, close to it is described into The pore size filter of the filtration core of water pipe is greater than the pore size filter of the filtration core far from the water inlet pipe.

Through the above technical solutions, water sample can be filtered for multiple times in multiple filtration cores, filter effect is improved.

Further, spacing block is provided between the adjacent filtration core, the spacing block can not pass through the filtration core.

Through the above technical solutions, spacing block is avoided that adjacent head core is bonded, prevent the hole on filtration core by adjacent Filtration core is blocked.

Compared with prior art, the utility model has the beneficial effects that water sample enters in acquisition tank from water inlet pipe, pass through Collected by outlet pipe after filter core and strainer valve, the solid impurity in water sample is retained by filtration core and strainer valve, at this time mistake The position of filter core is far from water inlet pipe；After stopping sampling, high-pressure pump or high-pressure water tank be passed through into cleaning pipe high pressure gas or Person's high pressure water, the solid impurity for passing through filtration core is pressed into filtration core close to the side of water inlet pipe again, while pushing filtration core And sealing ring shaves the inner wall of acquisition tank, then opens the convenient side in filtration core of cleaning lid and take out solid impurity, reduction is adopted Collect the cleaning difficulty of tank, improves the cleaning effect of acquisition tank.
