COMPLEX PLANT FOR DETERMINING QUALITY OF RIVER WATER

The invention relates to a complex plant meant to determine the quality of water in rivers, by in-situ monitoring, in real time, certain physical-chemical parameters, depending on the water flowing rate, the water level, the weather and environmental factors, intended for applications in geology and geoecology. According to the invention, the complex station is located within a module (1) made of UV- and weather-resistant plastics, mounted on a metallic cantilever (12) fixed into the bank ground and to the river bottom, while, at its upper part, the module (1) has mounted, on a vertical metallic arm, the following elements: a weather station (2), a video surveillance camera (4), a photovoltaic panel (3), and inside the module (1) there are: a data transmission system (5), a control panel (6), the apparatuses (7) for measuring the physical and chemical parameters, such as pH, temperature, electric conductivity, salinity, oxygen content, solid suspension, turbidity, as well as a secondary battery (8) of 12 V. A sliding float device (9) is mounted in connection with the cantilever (12) and has fixed thereon a support provided with measuring electrodes (10), being permanently submerged at a depth of about 15 cm from the water surface, the electrodes (10) being connected to the apparatuses (7) for measuring the physical and chemical parameters and being provided, in the area of the measuring cell, with an automatic wiper which, at each measuring cycle, removes sediments, solid suspensions and vegetal remains therefrom. Invenţia se referă la o staţie complexă pentru determinarea calităţii apei curgătoare, prin monitorizarea in situ şi în timp real a unor parametri fizico-chimici în funcţie de viteza de curgere a apei, nivelul apei, factorii meteorologici şi de mediu, cu aplicaţii în geologie şi geoecologie. Staţia complexă, conform invenţiei, este amenajată în interiorul unui modul (1) realizat din material plastic rezistent la intemperii şi la razele UV, montat pe o consolă (12) metalică fixată în malul de pământ, cât şi de fundul apei, la partea superioară a modulului (1), pe un braţ metalic vertical fiind fixate: o staţie meteo (2), o cameră video (4) de supraveghere, un panou fotovoltaic (3), iar în interiorul modulului (1) fiind montate: un sistem (5) de transmitere a datelor, un panou de comandă (6), aparatura (7) de măsurare a parametrilor fizico-chimici ca, de exemplu,H, temperatură, conductivitate electrică, salinitate, conţinut de oxigen, suspensie sol
