Piezoelectric driving local single-point push-broom type water quality state detection device and push-broom method thereof

Abstract

The invention discloses a piezoelectric driving local single-point push-broom type water quality state detection device and a push-broom method thereof. The device comprises a multi-shaft rotating bracket arranged on a water surface carrying platform, a piezoelectric ceramic driving array, and an optical single-point detector. The piezoelectric ceramic driving array is formed by vertically arraying a plurality of piezoelectric ceramic drivers which are arranged in a central symmetry manner and is formed in a mechanical shell, and the optical single-point detector is connected with the piezoelectric ceramic driving array through a pressure bearing plate; the bearing plate is fixedly connected with the optical single-point detector and flexibly connected with the mechanical shell of the piezoelectric ceramic driving array, and the mechanical shell of the piezoelectric ceramic driving array is fixed to the multi-axis rotating bracket. Local single-point detection of the water quality state is achieved, centralized processing is conducted after data collection and storage, water surface floating objects and near-shore water area submerged reefs are detected and recognized, a situationthat the water quality detection device touches the reefs when moving autonomously is avoided, and safety accidents are prevented.

Description

technical field [0001] The invention relates to a water quality state detection device and a method thereof, in particular to a piezoelectric-driven local single-point push-broom water quality state detection device and a push-broom method thereof, belonging to the technical field of state monitoring of special intelligent equipment. Background technique [0002] At present, water quality monitoring devices are widely used in hydrological environment, agriculture, fishery, quality inspection and monitoring, etc., and are the main equipment for detecting water quality status. There are also many types of sensors used for water quality monitoring. Commonly used water quality sensors include ORP sensors, turbidity sensors, PH sensors, conductivity sensors, and residual chlorine sensors. The water quality testing requirements of different industries are also very different. Water quality parameters also vary and therefore require different sensors. [0003] The problem brought ...

AI Technical Summary

Problems solved by technology

[0003] The problem brought about by this is that the configuration of the detection equipment is complicated, and additional communication / power supply communication and interfaces need to be configured or carried, making it difficult to realize multi-variable water quality monitoring of a single device

In addition, the use of conventional water quality sensors to detect water quality in open waters requires the use of ships or the construction of specific water observation stations, requiring heavy equipment design and manufacturing processes; at the same time, the miniaturization of the integrated system is difficult due to the complexity of equipment
