Problems solved by technology

[0004] At present, the existing spectrum analyzers are mostly used in laboratories or industrial production, which are not suitable for online monitoring of water quality, let alone put the spectrum analyzers in water, and these spectrum analyzers have problems such as large size, harsh use environment requirements, spectral range Disadvantages such as narrowness and high maintenance costs
Most underwater measurement devices are cleaned by air compression, which not only wastes energy, but also makes a lot of noise, which does not conform to the concept of environmental protection
Some equipment does not have an automatic cleaning function, which requires a lot of manpower to maintain, and cannot be cleaned in real time, resulting in a short service life of the instrument, low reliability and many other problems

Embodiment Construction

[0037] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

[0038] Such as figure 1 As shown, the present invention describes an on-line broad spectrum water quality analyzer, which includes two light paths. The optical device of a light path comprises a ultraviolet-visible light source 1, the first optical window 7 that is connected with this ultraviolet-visible light source 1 by optical fiber, the second optical window 11 that is arranged opposite to this first optical window 7, and this second optical window 11 An ultraviolet-visible spectrum detector 17 connected by an optical fiber. A fiber collimator 5 is provided at the connection between the first optical window 7 and the optical fiber, and a fiber collimator 13 is also provided at the connection between the second optical window 11 and the optical fiber. Parallel arrangement between the first optical window 7 and the second optical wind...

Abstract

The invention provides an on-line broad-spectrum water quality analyzer, which is characterized by comprising an ultraviolet visible light detection device, a near infrared light detection device, a controller in circuit connection with the ultraviolet visible light detection device and the near infrared light detection device respectively, a head shell, a connecting plate connected with the head shell, and a tail shell connected with the connecting plate, wherein the head shell, the connecting plate and the tail shell have sealing structures. Optical devices are hermetically arranged in a sealed inner chamber and are connected by optical fibers simultaneously, so that equipment meets the requirement of on-line underwater using and the using environment of the equipment is further widened; and spectrums of an ultraviolet visible light source and a near infrared light source are combined into a broad spectrum, so that a detection spectrum can cover a wider spectrum range.

Description

[0001] technical field [0002] The invention relates to an analyzer in the technical field of photoelectric detection, in particular to an ultraviolet, visible and near-infrared online wide-spectrum water quality analyzer. Background technique [0003] Spectrum analyzers have a wide range of applications, such as studying the radiation of matter; studying the interaction between light and matter; studying the structure of matter, quantitative and qualitative analysis of matter content; detecting the size, mass, temperature, and speed of motion of distant stars and the sun and directions etc. In mining, metallurgy, petroleum, chemical and other industries, spectrum analyzers are used for qualitative and quantitative analysis of substances, which is one of the main means to control product quality; in biochemistry and medicine, spectrum analyzers are used for trace element content analysis. The application of spectrum analyzer in water quality monitoring is a new field. [...
