Water quality monitoring device

Abstract

The invention relates to a water quality monitoring device. The device comprises a test sensor, a processing chip and a positioning and transmission unit, wherein the test sensor comprises a light source emitter, a sample flow cell and a light source detector; light transmitting pieces are arranged at a light path inlet end and a light path outlet end of the sample flow cell respectively; the surfaces of the light transmitting pieces are polished and plated with light transmitting hydrophobic films. The surfaces of the light transmitting pieces are polished and plated with light transmitting hydrophobic films, so that the light transmitting pieces can have the hydrophobic property, tiny bubbles attached to the surfaces of the light transmitting pieces can be reduced, light ray refraction,diffuse reflection and other phenomena can be reduced, and the transmittance at an ultraviolet-visible light waveband can be improved. Meanwhile, the surface contact angle between water and the lighttransmitting hydrophobic films is enlarged, thus, the surfaces of the light transmitting pieces cannot be soaked by water, the possibility of absorption of dust in water is reduced, and the light transmittance and the like are improved.

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
