Problems solved by technology

However, in the actual operation process, it was found that the water flow of the building drainage impacted the tipping bucket or the water flow splashed out, resulting in distortion of the water volume monitoring, which was greatly limited in the actual building drainage monitoring

Embodiment 1

[0016] This embodiment is an intermittent drainage monitoring system, figure 1 It is a cross-sectional view of this embodiment, which shows the dimensional relationship between the monitoring system and the monitored drainage pipe and the working principle of the system; figure 2 is a three-dimensional stereogram of the present embodiment, figure 1 with figure 2 The same numbers represent the same parts. This embodiment includes: a water measuring tank 1 and an auxiliary water storage tank 2 installed at the end of the drain pipe 3, and the water measuring tank 1 and the auxiliary water storage tank 2 are connected components with different functions. The cross-section of the water measuring tank 1 is a 270° cutting circle, which is composed of symmetrical left and right petals, and is installed on the bracket 10. Its working principle is that the hydraulic drive device 9 pushes the side walls on both sides of the water measuring water to rotate on an arc-shaped track. , ...

Embodiment 2

[0023] This embodiment is an improvement of the first embodiment, and it is an improvement of the first embodiment about automatic counter data reading and storage. The automatic counter described in this embodiment.

[0024] The data of the automatic counter is transmitted to the data workstation (PC or other electronic data processing device) through the relay installed nearby, so as to realize the regular storage of data and facilitate the reading and statistics of monitoring data.

Abstract

The invention discloses a monitoring system for intermittent drainage water volume, comprising: a water measuring tank and an auxiliary water storage tank installed at the end of a drain pipe, a hydraulic power device for driving the side wall of the water measuring tank to rotate, and an electronic counter for recording the number of rotations of the side wall . The water measuring water tank of the present invention implements quantitative drainage, and monitors the drainage water volume by measuring the number of times of drainage. The continuous monitoring of the amount of discharged water is realized through alternately receiving water from the water measuring tank and the auxiliary water storage tank. At the same time, fully considering the intermittency of the drainage water volume and the difference in the water volume, the invention is installed at the end of the drain pipe to ensure that all the large and small water volumes of the drainage flow into the water measuring tank, and realize the accurate measurement of the drainage water volume. The present invention solves the problem of drainage water monitoring, especially the precise measurement of urban sewage water volume, by monitoring the intermittent drainage water volume, fills the technical gap in accurate monitoring of intermittent drainage water volume, and provides technical support for urban hydrological monitoring.

Description

technical field [0001] The invention relates to a water volume monitoring system and method, which is a monitoring system suitable for free-flowing drainage water volume, a system that can be used for both pipelines and U-shaped channel water volume monitoring, and an urban hydrological monitoring system. The system and method are a system and method suitable for automatic monitoring of intermittent drainage water volume in the field of urban water circulation. Background technique [0002] Urban drainage (sewage and rainwater) is an important source of urban sewage and an important link in the urban hydrological cycle. With the acceleration of urbanization, the expansion of urban area, the increase of population, the increase of urban water consumption, the amount of urban drainage (or sewage) also increases. increase. However, since the drainage (or sewage) is an intermittent flow and contains many impurities, it cannot be accurately measured with traditional pipeline wat...
