Abstract
This utility model relates to the field of river monitoring technology and discloses a sewage sampling device for river monitoring, including a round rod. One end of the round rod is fixedly connected to a bracket, and a sampling cylinder is fixedly connected to the surface of the bracket. The other end of the round rod is fixedly connected to a handle. An extension plate is fixedly connected to the arc surface of the sampling cylinder, and a fixing rod is fixedly connected to the surface of the extension plate. A cover plate is fitted onto the surface of the fixing rod, and a spring is fitted onto the surface of the fixing rod. The two ends of the spring are fixedly connected to the fixing rod and the cover plate, respectively. A through hole is formed on the surface of the round rod, and a drive plate is slidably connected to the inner wall of the through hole. A rope slidably passes through the inner wall of the through hole, and one end of the rope is fixedly connected to the drive plate. This sewage sampling device for river monitoring, by setting up a sampling structure, facilitates the operation of the sampling cylinder to accurately sample sewage at a suitable depth, thereby ensuring the accuracy of sewage monitoring data.
