The specific use method of the test device comprises the following steps:
the experimental device is generally installed on the wall of the sedimentation tank at the inlet, and when the experimental device is installed, half of the fixing frame 1 can be positioned below the normal water surface and half can be positioned above the water surface. The laboratory cylinder 2 can be submerged in the pool water or left from the water surface by pushing and pulling the slider rod 32. When the water sample is taken out to carry out the quiet heavy experiment as needs, open the through-hole 21 of a laboratory cylinder 2, push down slider pull rod 32 for laboratory cylinder 2 is whole to be submerged in pond aquatic, and under the state at this moment, turbidity probe 4 still can survey the turbidity change in a timely laboratory cylinder 2.
Further, in the experimental test, the step of closing the through hole 21 is also included, so that the interference of the sediment environment in the experimental cylinder 2 caused by the sinking of the suspended matters in the upper water level is avoided.
Further, still including the step of sealing the end of a section of thick bamboo mouth under the section of thick bamboo 2, need push down connecting rod 23 this moment for the section of thick bamboo 2 is along pillar 35 downstream, makes bottom section of thick bamboo ring 22 hug closely down extension board 34, can make the water sample of obtaining in the section of thick bamboo 2 effectively keep apart with the water in the sedimentation tank outside the section of thick bamboo like this, and section of thick bamboo 2 forms a confined space completely, has thoroughly avoided external interference.
Further, the lower surface of the bottom end cylindrical ring 22 and the upper surface of the lower support plate 34 may be respectively configured as a layer of rubber pad, so that they can achieve a very effective sealing effect by mutual pressing to a certain extent after they are contacted with each other.
Further, when necessary, the experimental method further comprises the step of observing the sedimentation process in due time, after sampling is completed, the through hole 21 is kept in a closed state, the sliding block pull rod 32 is pulled upwards, the support 2 moves upwards relative to the fixing frame 1, and then most of the experimental cylinder 2 is exposed out of the water surface.
