Technical Field

[0001] The utility model relates to the technical field of waste water sampling, in particular to an environment-friendly waste water sampling device for water quality monitoring. Background Art

[0002] As an important means to evaluate the water environment quality and protect water resources, water quality monitoring occupies an extremely important position in the field of environmental protection. Traditional water quality monitoring methods often rely on manual collection of water samples and then analysis and testing in the laboratory.

[0003] However, when the existing waste water sampling equipment needs to sample waste water at different depths, multiple sampling equipment and storage equipment are often required, and it is necessary to insert into the water multiple times for sampling. Not only is it extremely inconvenient to carry, but the sampling equipment inserted into the water multiple times may also sample the waste water at the same depth multiple times.

[0004] Therefore, an environment-friendly waste water sampling device for water quality monitoring is needed to solve the above problems. Summary of the Utility Model

A plurality of water storage cavities are coaxially arranged inside the sampling pipe. One end of each water storage cavity is connected to the outside through a water passing mechanism. A piston is slidably installed inside each water storage cavity. A driving frame is slidably installed inside the sampling pipe. A driving mechanism is arranged inside the driving frame. The driving mechanism is movably connected to the piston; by coaxially arranging a plurality of water storage cavities inside the sampling pipe and connecting each water storage cavity to the outside respectively, the device can sample waste water at different depths and store the sampled waste water separately.

[0007] In the above-mentioned environment-friendly waste water sampling device for water quality monitoring, the water passing mechanism includes a water passing hole coaxially opened at one end of the water storage cavity.

A first one-way valve is arranged inside the water inlet hole, and the first one-way valve is located between the filter screen and the water passing hole. A second one-way valve is arranged inside the water outlet hole. By arranging the first one-way valve and the second one-way valve, the waste water can only enter the water storage cavity from the water inlet hole, and the waste water in the water storage cavity can only flow out from the water outlet hole, which is convenient for control.

[0009] For the above-mentioned waste water sampling device for environmental protection type water quality monitoring, the piston is slidably installed inside the water storage cavity near one end of the water passing hole through a first spring.

The driving frame is in a U shape. The vertical section of the driving frame slides inside the driving slide cavity through a fourth spring. The horizontal section of the driving frame is located outside the sampling pipe, and the extension slide plate abuts against the driving frame.

[0011] For the above-mentioned waste water sampling device for environmental protection type water quality monitoring, the driving mechanism includes a locking hole and a retraction cavity. The locking hole is formed on one side of the extension slide plate close to the driving frame. The retraction cavity is formed inside the driving frame at a position matching the locking hole. A locking slider is slidably installed inside the retraction cavity through a third spring.

[0012] For the above-mentioned waste water sampling device for environmental protection type water quality monitoring, a plurality of outer sleeves are fixedly installed on the outer side of the horizontal section of the driving frame. The number of the outer sleeves is the same as that of the water storage cavities. A pressing head is slidably installed inside the outer sleeve through a second spring. The elastic force of the second spring is greater than that of the third spring. The extension slide plates on the sides of the plurality of water storage cavities are respectively connected with the plurality of pressing heads through pull ropes. By arranging a locking hole on the extension slide plate, slidably arranging a locking slider on the driving frame, and connecting the locking slider with the pressing head, to sample which water storage cavity, just press the corresponding pressing head. The corresponding locking slider will insert into the locking hole, then slide the driving frame to press down the piston, and then release the driving frame and the corresponding pressing head, so that the piston resets under the action of the first spring, and the waste water can be extracted, which is convenient for operation.
