Device for cleaning optical window by using ultrasonic

Abstract

The invention discloses a device for cleaning an optical window by using ultrasonic, which comprises a shell, and an ultrasonic device arranged in the shell through a sealing device, wherein the ultrasonic device comprises a controller, an inverter, an ultrasonic generator and an ultrasonic transducer which are sequentially connected through a circuit; the controller is connected with the ultrasonic generator through a circuit; and the optical window is arranged in a range of a column body with a vibration surface of the ultrasonic transducer as a bottom surface. The device for cleaning the optical window by using the ultrasonic can realize online automatic cleaning of the optical window of a photoelectric water-quality monitoring device, is uniform in cleaning the optical window, can effectively improve the cleaning effect, and has the advantages of energy saving, environment protection performance and lower cost.

Description

technical field [0001] The invention relates to a cleaning device for an optical window in the field of online water quality monitoring, in particular to a device for automatically cleaning an underwater optical window by using ultrasonic waves, which belongs to the technical field of ultrasonic cleaning. Background technique [0002] At present, since water quality photoelectric monitoring devices need to be immersed in water for a long time to work, there is a common problem that the optical window is polluted due to long-term immersion in water of the water quality monitoring device, such as the growth of algae, microorganisms and sediment on the optical window. These problems will shorten the service life of the optical window and lead to the instability of the optical signal, reducing the reliability of photodetection. Therefore, it is very necessary to clean the optical window of the water quality photoelectric monitoring device. [0003] For optical windows that are ...

Problems solved by technology

However, these methods have problems such as uneven cleaning and narrow range of cleaning surfaces, and the use of the above methods requires complex mechanical structure design, high cost, large power consumption, and high noise, which cannot be separated from frequent manual maintenance.

For water quality photoelectric monitoring devices that require a high degree of intelligence, especially for water quality photoelectric monitoring devices that work online, the above method cannot achieve automatic cleaning, and is quite limited in actual operation.
