Problems solved by technology

Ultrasonic detection is greatly affected by underwater impurities, and cannot measure the distribution and density of floating mud
Since there is no clear interface between the deposited silt layer and the water layer, silt detection has not yet found an accurate method

Abstract

The invention discloses a river silt detecting device which comprises a silt probe (1), a water pumping pipe (2), a metering water pump (3) and a photoelectric detector (4). The metering water pump (3) is mounted on the water pumping pipe (2), a water inlet of the water pumping pipe (2) is communicated with the upper portion of the silt probe (1), a water outlet end of the water pumping pipe (2) is connected with the photoelectric detector (4), the silt probe (1) comprises a probe barrel (11), an electromagnetic valve (12) and a clear water pipe (13), the electromagnetic valve (12) is arranged on the bottom surface of the probe barrel (11), the clear water pipe (13) is arranged on a side wall of the bottom of the probe barrel (11), an opening of the clear water pipe (13) floats for at least five meters, a touch switch (14) is mounted on the bottom surface of the probe barrel (11), and the electromagnetic valve can be closed under the control of the touch switch (14). The river silt detecting device has the technical advantages of little disturbance on silt, zero radioactive hazards, safety in use, simple structure, easiness in operation and measurement and capability of accurately measuring the thickness of the silt.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring, and in particular relates to a river silt detection device. Background technique [0002] With the acceleration of urbanization, rapid economic development and increasing population, the pollution and siltation of urban rivers are gradually increasing. On the one hand, rivers receive urban sewage for a long time and are scoured during the rainy season, resulting in river siltation, which seriously affects the water ecological environment; Sludge is formed. River siltation will reduce the flood capacity of the river, increase the risk of disasters, and may cause floods during heavy rains during the flood season. Therefore, river dredging is of great significance for flood discharge and water ecological environment protection. [0003] At present, the common mud measurement methods at home and abroad include exploration drilling sampling, static penetrating sounding, radiation d...
