Problems solved by technology

[0002] The sediment content in the water in the central and western regions of my country and the Yellow River irrigation area is relatively large, and the channels are prone to silt. Under such conditions, ordinary sensors cannot accurately complete the actual water level measurement; Siltation occurs, and because the silt thickness of the wide river channel is uneven on the same section, it is difficult to measure the accurate cross-sectional area of ​​the river channel water delivery. It is also difficult to measure the silt thickness accurately under such conditions with ordinary sensors. Measure the accurate cross-sectional area of ​​river water delivery, and there is a large error in the flow measured by the velocity-area method or the water level-formula method

Embodiment 3

[0040] Embodiment three, with reference to the attached Figure 4 , used to measure the silt thickness of general rivers or channels, the silt thickness sensor 8 is set at the bottom of the river or channel, using the different specific gravity of silt and water, the pressure is transmitted through hydraulic pressure, and the weight of sand and water is measured. The pressure is changed into an electric signal, combined with the water level signal measured by the water level gauge 10, the silt thickness is calculated by using the specific gravity of the canal water and the water-containing silt through the silt channel flow meter 7 .

Embodiment 4

[0041] Embodiment four, with reference to the attached Figure 5 , 6 , used to measure the silt thickness of wide rivers or channels, silt wide river flow meter 12, multiple silt thickness sensors 2, flow velocity meter 3, water level gauge 4, rectangular water delivery section 5, multiple silt thickness sensors 8 Distributed on multiple points at the bottom of the rectangular water delivery section 11, the flow meter 9 is also arranged inside the rectangular water delivery section, the water level gauge is installed above the water surface, and a plurality of silt thickness sensors, flow velocity meters, and water level gauges are all connected with the silt width. The river channel flow meter 12 is connected. A straight line formed by a plurality of silt thickness sensors installed at multiple points at the bottom of the rectangular water delivery section 11 is parallel to the rectangular water delivery section, that is, perpendicular to the river course or channel.

Abstract

The invention relates to silt thickness sensors and a method for measuring thickness of silt in river channels or channels with the same, in particular to special sensors and method for measuring thickness of silt in wider river channels or channels in the water conservancy industry. The technical scheme is as follows: a sealed case (1) of the silt thickness sensor is divided into upper and lowerparts, wherein the upper part is a hydraulic cavity (2) filled with pressure transmission media; the lower part is a sensor chamber (6) for placing a pressure sensor (3); a corrugated diaphragm (4) is arranged at the upper part of the sealed case and is the top wall of the hydraulic cavity; the corrugated diaphragm transmits the pressure to the pressure transmission media in the hydraulic cavity under pressure; and the pressure sensor converts the pressure signal to the electrical signal and outputs the electrical signal. The method is characterized by arranging the silt thickness sensors on a plurality of points at the bottoms of the river channels or the channels, utilizing the different proportions of silt to water, utilizing the pressure transmission media to transmit pressure, measuring the weights of silt and water, using the pressure sensor to convert the pressure signal to the electrical signal, combining the water level signal and utilizing the proportion of water in the channel to silt containing water to compute the silt thickness.
