Embodiment 1

[0070] Embodiment one, with reference to the attached Image 6 , applied to reservoir water depth and sediment thickness monitoring.

[0071] A sedimentation and water level monitor is used to monitor the water depth and sedimentation thickness of a reservoir. It is realized by using the above-mentioned sedimentation and water level monitor. The characteristics of the application of the reservoir are: the water depth can change from a few meters to hundreds of meters, and the sedimentation change can be from a few meters to more than ten meters. In the application of the reservoir, the silt and water level monitor also includes a static pressure water level sensor 14 connected to the microcontroller, a water surface float 15 connected to the microcontroller through a waterproof cable 16, and the water surface float is matched with a monitoring host microcontroller, a wireless communication module and Lithium battery; the shell of the sedimentation and water level sensor is str...

Embodiment 2

[0081] Embodiment two, referring to the attached Figure 7 . It is used in the monitoring of river water level and sediment thickness.

[0082] A sedimentation and water level monitor is used to monitor the water level and sedimentation thickness of a river. It is realized by using the above-mentioned sedimentation and water level monitor. In the river application, floating objects are usually scraped and hanged, so boards should be installed in the river 19. The plate is set along the water flow and fixed on the bottom of the river. The sedimentation and water level monitor is installed vertically on the back edge of the plate. Most of the floating objects will be scraped and hung on the front of the plate facing the water, thereby reducing floating. The influence of pollutants on the measurement accuracy of sedimentation and water level monitors.

[0083] Include the following steps:

[0084] ①Fix the plate 19 firmly on the river bottom in the direction of the water flo...

Embodiment 3

[0093] Embodiment three, with reference to the attached Figure 7 , used in agricultural irrigation metering channel water level and sediment thickness monitoring.

[0094] A silt and water level monitor is used for monitoring the water level and silt thickness of agricultural irrigation metering channels, and its layout method and usage are the same as those used in river courses.

[0095] The difference is that in the application of the metering channel, the water level / flow relationship curve under different silts is determined according to the measured silt thickness rate of the metering channel, so as to improve the metering accuracy.

[0096] Include the following steps:

[0097] ①Among agricultural irrigation channels, a sloped, straight channel with a uniquely determined water level / flow relationship curve is called a "metering channel". However, this "uniquely determined water level / flow relationship curve" will accumulate with the bottom of the channel It is an i...

Abstract

The invention relates to a deposition and water level monitor and an application method thereof and belongs to the technical field of underwater deposition automatic monitoring in the water conservancy industry. According to the technical scheme, the deposition and water level monitor comprises a monitoring host (6) and a deposition and water level sensor (8), the deposition and water level sensor is in a strip shape, and a plurality of electrodes (7) are distributed in the length direction. The strip-shaped deposition and water level sensor is vertically and downwards arranged in the length direction, and the capacitance value of each electrode is measured; the deposition thickness is obtained in real time according to different capacitance values of all the electrodes and intervals between every two electrodes. By means of the deposition and water level monitor and the application method thereof, the water level and decomposition can be monitored at the same time, water surface and water bottom can be monitored at the same time, the decomposition thickness and the water level height can be monitored for a long time without manual intervention, then deposition rules of sludge and water level change situations are analyzed, and storage capacity or water flow is measured. The deposition and water level monitor and the application method thereof are high in accuracy, high in real-time performance, easy to arrange and small in later-period maintenance amount.

Description

technical field [0001] The invention relates to a sedimentation and water level monitor and an application method thereof, belonging to the technical field of automatic monitoring of underwater sedimentation in the water conservancy industry. Background technique [0002] For the monitoring of sediment thickness, there is no simple, low-cost, and long-term continuous monitoring method at present. In many fields or occasions, monitoring the speed and thickness of silt deposition is of great significance, such as: monitoring of reservoir water depth and silt thickness, river water level and silt thickness monitoring, agricultural irrigation metering channel water level and silt thickness monitoring, pipeline silt thickness monitoring Etc. It is very difficult to rely on ordinary equipment or manpower to monitor, and the sedimentation will cause the monitoring equipment to fail to work. How to realize simple and low-cost automatic monitoring of sedimentation is a big problem in...
