Description

Technical Field

[0002] With the development of industry, water pollution is becoming more and more serious. After being discharged, the polluted water is concentrated in designated treatment pools. In order to detect the effect of sewage treatment, it is necessary to take samples of water in designated areas from time to time.

[0003] The existing announcement number is CN216284456U, and the name is a sewage sample collection device, a sampling cylinder, which is used to collect sewage samples. The top of the sampling cylinder is connected to a cylinder cover, and the surface of the sampling cylinder is connected to a water outlet hose, and the water outlet hose can take out the sewage sample inside the sampling cylinder. The surface of the sampling cylinder is provided with a sampling outer frame, a water inlet, which is opened at the bottom of the sampling cylinder, and a round hole is opened at the bottom of the sampling cylinder. A limit rod runs through the inside of the round hole, and a baffle is connected to the top of the limit rod, and a rubber ring is connected to the bottom of the baffle. The surface of the baffle is connected to a connecting rod. A connecting rod and a float block are connected to the top of the connecting rod. The limiting rod slides inside the circular hole to limit the movement direction of the baffle. In the sewage sample collection device, the float block drives the baffle to float in the water through the connecting rod, so that the sewage can enter the sampling tube, which is convenient for collecting sewage samples inside the water body. Rotating the threaded rod can drive the internal threaded tube to move horizontally. When the internal threaded tube moves to the outside of the fixed groove, the sampling tube is pulled upward to facilitate the removal of the sampling tube. Rotating the rotating rod can drive the cleaning mechanism to rotate through the support frame, which is convenient for cleaning the inner wall of the sampling tube.

[0004] However, when sampling sewage, it is necessary to take out sewage samples of different depths. The top of the sampling tube is opened, which results in water samples of different depths entering the sampling tube as the sampling tube sinks, resulting in inaccurate water sampling and affecting the accuracy of water sample collection.
