Self-cleaning water quality detection device and water quality detection method

Abstract

The self-cleaning water quality detection probe comprises a floating body, a detection module, an end cover and a cleaning module, a floating cavity is formed in the floating body, and a control module is arranged in the floating cavity; the detection module is connected with the floating body and is positioned below the floating body; the detection module comprises at least one detection probe electrically connected with the control module; the end cover and the lower end face of the detection module are installed in a butt joint mode to form a containing cavity, the detection probe extends into the containing cavity, the cleaning module is located in the containing cavity, the cleaning module comprises an ultrasonic module, and the ultrasonic module is electrically connected with the control module; the ultrasonic module is used for detecting the cleanliness of the surface of the detection probe and cleaning the detection probe and the containing cavity. The device has the functions of real-time monitoring of the cleanliness of the detection probe and ultrasonic cleaning, can keep the cleanliness of the detection probe for a long time, and improves the detection precision.

Description

technical field [0001] The invention belongs to the technical field of water quality testing equipment, in particular to a self-cleaning water quality testing device and a testing method. Background technique [0002] Water is an indispensable substance in our life, it is the guarantee of our life, a good water source is crucial to our health, which requires a water quality testing device to check for us. However, the domestic water quality detection devices in the existing market generally cannot realize self-cleaning. The detection probes of the existing water quality detection equipment need to be soaked in the water body for a long time, and are easily attached by algae and particulate matter in the water body. As a result, the detection accuracy is reduced. In the prior art, there are technical solutions for cleaning water quality detection sensors by means of brushes or flushing. For example, the published Chinese patent application CN113624932A discloses an automatic...
