Water quality detection device and method and control system

Abstract

The embodiment of the invention discloses a water quality detection device and method and a control system. The device comprises a sample pool, a lifting piston, a transmission light source and a spectrograph, two optical windows are symmetrically formed in the side wall of the sample cell, and a first optical window sheet and a second optical window sheet are arranged on each optical window; the transmission light source and the spectrograph are respectively positioned on the outer sides of the first window sheet and the second window sheet, and are positioned at the same horizontal height with the optical window; a lifting piston is arranged in an inner groove of the sample pool, and a water diversion hole is formed in the bottom of the sample pool; when the lifting piston is located at the bottom of the sample cell, the water diversion hole is in a blocked state; when the lifting type piston moves upwards, the water diversion hole is in an open state; the upper portion of the lifting piston is fixedly connected with a suspender which is fixed through a top plate arranged on the top. The water quality detection device can automatically extract a water quality sample and detect the water quality sample, and can improve the accuracy of water quality detection by analyzing spectral data in different states.

Description

technical field [0001] The embodiments of the present application relate to the detection field, and in particular to a water quality detection device, method and control system. Background technique [0002] With the acceleration of urbanization and the development of regional economy, the load of local water resources has increased, and the problem of water pollution has gradually become one of the most important factors restricting my country's economic and social development, which has attracted great attention from the national and local governments. At this stage, water quality monitoring has become the largest market in the field of environmental monitoring in my country. [0003] In the existing methods, water quality monitoring methods are usually collected on-site, and usually need to be tested in the laboratory after manual sampling, but there are problems such as long detection period and easy to cause secondary pollution.
