Online measuring device for turbidity of water supply pipe network based on ultrasonic waves

Abstract

The invention discloses an online measuring device for the turbidity of a water supply pipe network based on ultrasonic waves. The online measuring device includes a water sample measuring vessel witha water inlet pipe and a water outlet pipe, one or more pairs of ultrasonic wave measuring transducers arranged in the water sample measuring vessel, an electrically controlled water pump, a main control module, a motor, and an electric actuator, wherein the water inlet pipe and the water outlet pipe are suitable for communicating with a to-be-measured water supply pipe network, the electricallycontrolled water pump is arranged in the water sample measuring vessel, and the electric actuator is connected to a rotating shaft of the motor; and the electrically controlled water pump is suitablefor switching the on-off state under control of the main control module, the electric actuator is provided with a blocking end and a cleaning end, and the main control module drives the rotating shaftof the motor to rotate, drives the electric actuator to open or close the water inlet pipe and the water outlet pipe, and cleans the ultrasonic wave measuring transducer. The online measuring devicecan automatically complete measuring tasks, automatically cleans the measuring surface at regular intervals, is free from the influence of the water supply velocity of the pipe network and the changeof the measuring device characteristics, and has the good measuring stability.

Description

technical field [0001] The invention relates to the field of water meter measurement, and more specifically relates to an ultrasonic-based online turbidity measurement device for a water supply pipe network. Background technique [0002] Carrying out online monitoring of water quality in water supply pipe network is an important measure for the country to ensure safe water supply in cities and towns. At present, the online monitoring of water quality in my country's water supply pipe network has the characteristics of narrow coverage, high monitoring cost, short maintenance cycle and heavy maintenance workload, and poor real-time early warning. According to the requirements of the "Implementation Rules (Trial)" of the "Technical Guidelines for the Construction and Renovation of Urban Water Supply Facilities" compiled by the China Urban Water Supply and Drainage Association, the on-line monitoring of water quality in factory water and pipe network water should be based on tur...

Problems solved by technology

Therefore, this type of instrument or sensor cannot be used directly in the water supply network, and it is necessary to establish a more complex measurement environment, limit the flow rate range in the water sample measurement container, etc.
