Embodiment 1

[0026] A detection device for real-time measurement of river silt thickness, including several measurement modules and a data receiving module, wherein the measurement module is used to measure the river silt thickness and transmit the measured data to the data receiving module;

[0027] The measurement module includes an LED lamp, a light intensity measurement sensor 2, a wireless emission chip 3, a power supply module 4 and a sealed tube with a diameter of 100 mm. The inside of the sealed tube is divided into several layers through opaque interlayers, and the height of each layer is 150 mm. LED lamps and light intensity measuring sensors 2 are arranged side by side on the inner wall of each layer, and the surface of each inner wall opposite to the light source 1 and light intensity measuring sensor 2 is provided with a transparent window of semicircular glass with a diameter of 100mm. Anti-glare film on the outside. Wireless transmitter chip 3 uses TI company CC2530.

Abstract

The invention discloses a detection device for measuring the thickness of riverway sludge in real time. The detection device is characterized in that it comprises a plurality of measuring modules anda data receiving module; the measuring module comprises a light source, a light intensity measuring sensor, a wireless transmitting chip, a power supply module and a sealing pipe; the interior of thesealing pipe is divided into a plurality of layers through opaque interlayers. The light source and the light intensity measuring sensor are arranged on the inner wall of each layer side by side; a transparent window is formed in the surface, opposite to the light source and the light intensity measuring sensor, of the inner wall of each layer; the light intensity measuring sensor is used for collecting illumination intensity data and transmitting the data to the wireless transmitting chip, the wireless transmitting chip converts the collected illumination intensity into a digital signal and transmits the digital signal to the data receiving module, and the power supply module is used for supplying power to the detection device. According to the detection device for measuring the thicknessof the riverway sludge in real time, the change of the sludge thickness is converted into the change of the light intensity, and the detection precision is higher.

Description

technical field [0001] The invention relates to the field of water conservancy engineering, in particular to a detection device for real-time measurement of river silt thickness. Background technique [0002] my country's water system is developed. Due to my country's rapid economic development in recent years, river soil erosion and water pollution have been serious. According to relevant statistics, about 1.4 billion tons of sediment are deposited in natural or artificial water bodies every year. A large amount of sedimentation will cause the river bed to rise, resulting in a decrease in the water storage capacity of the river, which will easily lead to floods during the flood season, endangering the lives and property of local residents. In addition, sedimentation at the bottom of the river will also affect the smoothness of the waterway. As a result, certain large-tonnage ships cannot pass. Therefore, it is important to be able to know the thickness of the river silt in...
