Description

Technical Field

[0001] The utility model relates to the technical field of sediment content testing, in particular to a river sediment content testing device. Background Art

[0002] The river sediment content test is to understand the sediment accumulation conditions of rivers, reservoirs and other water bodies by measuring indicators such as suspended sediment transport rate and bed sediment transport rate, so as to provide a scientific basis for the construction of related water conservancy projects.

[0003] A Chinese patent with application publication number CN209911177U discloses a river sediment content testing device. In the patent, the sampling device is placed into the river on a boat by a rope. At this time, the gravity of the lead fish drives the entire device to be pressed downward. As the device sinks, the river will cause upward pressure on the sampling box body, thereby pushing the pressure plate inside the pressure groove to move upward. At this time, the water in the river enters the interior of the sampling box body, and then the rope is pulled upward. As the sampling box body rises, the pressure of the river on it becomes smaller. Through the gravity of the pressure plate, the pressure plate sinks and continues to cover the inside of the pressure groove, thereby sealing the sampling box body. After the sampling box body is pulled ashore, the water flows out after pushing the pressure plate, and the measuring device detection structure is detected, achieving the purpose of convenient use.

[0004] When using the above patent, we found that the device does not have the ability to filter debris in the water, which makes it easy for large debris in the water to enter the sampling box, thereby affecting the test effect of the sediment content. Therefore, we proposed a river sediment content test device. Utility Model Content
