Water Quality Monitoring Device

Abstract

The invention relates to a water quality monitoring device, which includes a test sensor, a processing chip and a positioning transmission unit. The test sensor includes a light source emitter, a sample flow cell and a light source detector. The light path inlet end and the light path outlet end of the sample flow cell are respectively provided. There is a light-transmitting sheet, the surface of which is polished and coated with a light-transmitting hydrophobic film. By polishing the surface of the light-transmitting sheet and adding a transparent hydrophobic film, the present invention can make the light-transmitting sheet hydrophobic, reduce the tiny bubbles attached to the surface of the light-transmitting sheet, thereby reducing light refraction, diffuse reflection and other phenomena, and can improve the performance in the ultraviolet-visible light band. The transmittance is increased, and the surface contact angle between water and the light-transmitting hydrophobic film is increased, making the surface of the light-transmitting sheet less likely to be wetted by water, reducing the possibility of adsorbing dust in the water, thereby improving the light transmittance, etc.

Description

technical field [0001] The invention relates to the technical field of water body detection, in particular to a water quality monitoring device. Background technique [0002] According to my country's current national conditions, the market's main requirements for water quality monitoring equipment are: it can be used under harsh conditions, it is easy to maintain and low in cost; it is easy to maintain and operate, intelligent, and has strong anti-interference ability; the scalability of monitoring parameters is strong; Can effectively play the environmental early warning and monitoring capabilities. Accordingly, the future development trend of my country's water quality monitoring instruments is mainly to improve the ability to adapt to complex site environments; to develop in the aspects of high quality, multi-function, generalization, integration, automation, systematization and intelligence. Therefore, the water environment monitoring technology based on spectral sensor...

AI Technical Summary

Problems solved by technology

[0004] Spectral water quality monitoring equipment has also been used in environmental protection and chemical industries, but the application in the water conservancy and water quality monitoring industry has not been able to make breakthroughs. In addition to the price, the important reason is that water bodies are diverse, and some water bodies are of poor quality. Larger, after the surface of the optical component is immersed in water, it is easy to absorb dust in the water, resulting in high turbidity, serious mirror pollution, and optical testing cannot be effectively realized
