Abstract
The utility model provides a sediment observer. The sediment observer comprises a connection rope; the upper end of the connection rope is connected with a foam ball, and the lower end is divided into a left rope and a right rope; the lower end of the left rope is fixed on a left hook, and the lower end of the right rope is fixed on a right hook; the left hook is welded on a semicircular left-half cover plate, and the right hook is welded on a semicircular right-half cover plate; the cover plates are connected together with a collection barrel through hinges. The sediment observer further comprises two reset springs. When the sediment observer sinks to the bottom, the left-half cover plate and the right-half cover plate can be separated from each other to expose the upper-end opening of the collection barrel under the elastic force of the two reset springs, and the collection barrel collects the sediment. When the sediment observer is lifted, the left-half cover plate and the right-half cover plate can be combined together to cover the upper-end opening of the collection barrel under the pull force of the left rope and the right rope, and the disturbance of water flow to the sediment is avoided. The sediment observer provided by the utility model can be used for positioning a special point accurately without causing disturbance to a sample.
