The outer wall of the sealing pad 10 is tightly matched with the inner wall of the sampling tube 3, and when the sealing pad 10 rotates, sewage can not enter and exit from between the outer wall of the sealing pad 10 and the inner wall of the sampling tube 3.

The water outlet 13 is smaller than the first water inlet 11, and the water outlet 13 is small enough, so that when the sampling cylinder 3 is filled with water, sewage cannot flow out of the water outlet 13 as long as the first water inlet 11 and the second water inlet 12 are not corresponding.

The working principle of the utility model is as follows: the working principle of the sampler will be described from the process of collecting sewage.

Firstly, it should be noted that, in order to know when the first water inlet 11 and the second water inlet 12 are corresponding when the second telescopic device 9 is rotated, we use a mode of adding a marking line to perform marking, and specifically disclosed as follows:

the utility model discloses a water sample is sealed to telescoping device 8 and No. two telescoping device 9 on all set up the mark line, when two mark lines correspond, no. one water inlet 11 also corresponds with No. two water inlets 12, satisfies the demand of intaking the sample, when two mark lines stagger, no. one water inlet 11 and No. two water inlets 12 then do not correspond, satisfies the demand of intaking the back sealed water sample.

As shown in fig. 1, fig. 2 and fig. 3, when sewage needs to be collected, a worker brings a sampler to the side of an aeration tank, rotates the second telescopic device 9 first, the second telescopic device 9 drives the pumping rod 4 and the sealing gasket 10 to rotate inside the sampling cylinder 3, the first water inlet 11 corresponds to the second water inlet 12, then the length of the first telescopic device 8 is adjusted, the length of the second telescopic device 9 also changes along with the first telescopic device 8, the bottom of the sampling cylinder 3 is slowly immersed in the sewage, the sewage enters the sampling cylinder 3 from the first water inlet 11 and the second water inlet 12, when the sampling cylinder 3 is filled with the sewage, the second telescopic device 9 is rotated again, the first water inlet 11 and the second water inlet 12 are not corresponding, at the moment, the sealing plate 14 and the sealing gasket 10 are in a closed state, and the pressure outside the sampling cylinder 3 is larger than the pressure inside the sampling cylinder 3 because the water outlet 13 is smaller than the diameter of the sampling cylinder 3, finally the first telescopic device 8 is adjusted to be short, the sewage needs to be detected, the second telescopic device 9 is rotated when the sewage needs to be detected, the second water inlet 11 and the second telescopic device is detected, the pressure inside the second water inlet 3 is detected, the pressure is high enough to be detected, the pressure inside the working instrument is detected, and the like the working instrument is detected, and the pressure is high when the pressure is detected, and the pressure is high, and the pressure is detected.

It should be noted that, in order to save more time and effort, the first telescopic device 8 and the second telescopic device 9 may also be provided as electric telescopic rods. The gasket 10 may be made of rubber or the like.

The sampler can also collect sewage in the deep part of the aeration tank, and specifically operates as rotating the second telescopic device 9 firstly to enable the first water inlet 11 and the second water inlet 12 not to correspond, at the moment, the sealing plate 14 and the sealing gasket 10 are in a closed state, after the sampling cylinder 3 is slowly immersed in the sewage, the diameter of the water outlet 13 is smaller, when the sampling cylinder 3 just enters the sewage, the pressure in the water is small, the sewage cannot enter the sampling cylinder 3, when the sewage slowly enters the deep part of the sewage, the second telescopic device 9 is rotated again to enable the first water inlet 11 and the second water inlet 12 to correspond, the sewage enters the sampling cylinder 3, when the sewage does not need to be continuously collected, the second telescopic device 9 is rotated to enable the first water inlet 11 and the second water inlet 12 not to correspond, and the sealing plate 14 and the sealing gasket 10 are in a closed state, so that the collected sewage can better detect the activated sludge condition in the deep part of the aeration tank.

If the sampling cylinder 3 is broken, or when the sampling cylinder 3 needs to be cleaned, a worker can detach the bolts, separate the sampling cylinder 3 from the first fixing ring 5 and the second fixing ring 6, and replace or clean the sampling cylinder 3, and install the sampling cylinder again, so that the waste of resources is avoided, the cleanliness of sampling tools is also maintained, and convenience is provided for subsequent sampling work.
