Description

Technical Field

[0001] The utility model relates to the technical field of river channel silt thickness detection, in particular to a river channel silt thickness detection device. Background Art

[0002] The siltation of the river has increasingly affected the normal performance of various functions such as flood control, drainage, irrigation, water supply, and navigation. In order to restore the normal functions of the river and promote the rapid and sustainable development of the economy and society, the river dredging project is carried out. The river is deepened and widened through management, and the river water is cleared. The production conditions and living environment of the masses are significantly improved, and the goal of "clear water, smooth river, green bank, and beautiful scenery" is achieved. When cleaning the silt, it is necessary to detect the thickness of the silt for cleaning.

[0003] The authorization announcement number CN 216645167 U discloses a precise river channel silt thickness detection device, which involves the field of river channel dredging, including a detection cylinder, both sides of which are fixedly installed with measuring racks, and one side of one of the measuring racks is provided with a measuring scale. In the practical new model, the detection device is slowly placed vertically into the river channel and inserted into the silt, the pressure plate contacts the silt surface, the pressure plate has a large area, and the pressure on the silt is small, and it stays on the silt surface, and the detection cylinder continues to go deeper until the detection device is difficult or impossible to insert, which means that the conical insert is in contact with the riverbed, and the device is taken out. Under the action of the clamping rod, the clamping rod fixes the wheel, thereby fixing the sliding gear, so that the position of the sliding box and the pressure plate is fixed, so that when the device is taken out, the silt thickness can be read according to the measuring scale, without sampling and testing, and accurate detection can be performed when the silt is thin.

[0004] However, the detection device has the following shortcomings: when the device is used, the entire detection cylinder is inserted into the river silt, and the thickness of the river silt is detected by the telescopic length of the pressure plate. However, the diameter of the detection cylinder is often thicker to facilitate the installation of related devices, which makes it inconvenient for operators to insert it into the river silt. At the same time, after it is inserted into the silt, a large amount of silt will adhere to the surface, and the silt will cover the measuring scale on one side, which is not convenient for subsequent readings and limits the use effect.
