Sewage water quality monitor

Abstract

The invention discloses a sewage water quality monitor, which comprises a shell, wherein the lower part of the shell is connected with a rotating shaft; the lower end of the rotating shaft passes through the wall of a tap water pipe and is arranged in the tap water pipe; the part, which is located inside the tap water pipe, of the rotating shaft is equipped with fan blades; the shell is internallyprovided with a power generation module which is connected with the rotating shaft and used for converting kinetic energy generated when water flow impacts the fan blades into electric energy; a water quality monitoring functional module is arranged in the shell and positioned above the power generation module; a power supply processing module is arranged in the shell, positioned between the power generation module and the water quality monitoring functional module, electrically connected with the power generation module and used for converting electric energy output by the power generation module into electric energy which can meet power utilization requirements of the water quality monitoring functional module; and the water quality monitoring functional module is electrically connectedwith the power supply processing module. The sewage water quality monitor can generate power by using the water flow in the tap water pipe and supply the electric energy to the water quality monitoring module, thereby enabling the water quality monitoring module to monitor the water quality in real time.

Description

technical field [0001] The invention belongs to the technical field of water quality monitoring, and in particular relates to a sewage water quality monitoring instrument. Background technique [0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in the water body, the concentration and change trend of various pollutants, and evaluating the water quality status. The scope of monitoring is very wide, including unpolluted and polluted natural water (rivers, rivers, lakes, seas and groundwater) and various industrial drainages. The main monitoring items can be divided into two categories: one is comprehensive indicators reflecting water quality, such as temperature, color, turbidity, pH value, conductivity, suspended matter, dissolved oxygen, chemical oxygen demand and biochemical oxygen demand etc.; the other category is some toxic substances, such as phenol, cyanide, arsenic, lead, chromium, cadmium, mercury and organic pestic...

AI Technical Summary

Problems solved by technology

[0005] Existing household sewage water quality monitors generally use external power supply for water quality monitoring, so if there is a long-term power outage, water quality monitoring cannot be carried out in a timely and effective manner, and the role of the sewage water quality monitor cannot be fully utilized
