Timing sampling device for sewage detection

Abstract

The invention relates to the technical field of sewage detection, and discloses a timing sampling device for sewage detection; the timing sampling device comprises a base; a driving rod is movably connected above the base; the inner side of the driving rod is movably connected with a rotating rod, and the other end of the rotating rod is hinged with a connecting rod I. When an extraction box rotates to pass through a protruding part of a cam, a pressing plate can drive a piston to move downwards and then upwards, so that the air pressure in a liquid storage cavity is reduced, the detected sewage is pressed into the liquid storage cavity by external atmospheric pressure, the extraction process is convenient and efficient, and due to the fact that the three sets of extraction boxes are arranged, the average value of detection results is obtained, and it is guaranteed that the detection results are accurate and effective; the rotating rod is in one stroke, a movable plate is driven by the connecting rod to complete the step of placing a dustproof cover from a grabbing belt, the external environment is prevented from polluting an extracted sample, the detection results are more accurate; the power source of the movable plate provided with the dustproof cover is still the driving rod, a new motor does not need to be added, the cost is reduced, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of sewage detection, in particular to a timing sampling device for sewage detection. Background technique [0002] With the rapid development of our country's economy, more and more factories of all kinds are spreading around our lives. While factories create their own value, their pressure on the environment is also worrying. Some factories often The sewage that meets the standards is discharged to the earth or rivers, which has a certain impact on people's physical and mental health. [0003] In order to comply with the new national policy on energy saving and environmental protection, manufacturers often need to use sewage testing and sampling devices to sample and test the treated sewage to ensure that the pollution to the environment is reduced. In order to ensure the qualified discharge of sewage, the outlet pipes of the sewage treatment plant Generally, multiple sampling and testing are required in o...

[0003] In order to comply with the new national policy on energy saving and environmental protection, manufacturers often need to use sewage testing and sampling devices to sample and test the treated sewage to ensure that the pollution to the environment is reduced. In order to ensure the qualified discharge of sewage, the outlet pipes of the sewage treatment plant Generally, multiple sampling tests are required in one day, and the staff have to take samples for testing every once in a while. The process is cumbersome and inefficient.
