Description

Technical Field

[0001] The utility model relates to the technical field of environmental detection, in particular to the field of water quality monitoring, and specifically is a water quality monitoring buoy. Background Art

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating the water quality. The monitoring scope is very wide, including unpolluted and polluted natural water (rivers, lakes, seas and groundwater) and various industrial drainage. The main monitoring items can be divided into two categories: one is the comprehensive indicators reflecting the water quality, such as temperature, chromaticity, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand and biochemical oxygen demand; the other is some toxic substances, such as phenol, cyanide, arsenic, lead, chromium, cadmium, mercury and organic pesticides. In order to objectively evaluate the water quality of rivers and oceans, in addition to the above monitoring items, it is sometimes necessary to measure the flow rate and flow.

[0003] Patent No. CN109895956A discloses a marine buoy, wherein the buoy is provided with an instrument well for accommodating instruments, and also includes a positioning frame, a fixing frame and a locking cover, wherein the positioning frame is fixed in the instrument well, and the positioning frame is provided with a plurality of positioning grooves along the circumference of the instrument well; the instrument is locked at the lower end of the fixing frame, and the upper end of the fixing frame is provided with a plurality of cantilevers adapted to the positioning grooves, during installation, the instrument is placed into the instrument well from the center of the positioning frame, and the end of the cantilever is screwed into the positioning groove from the side of the positioning groove; the locking cover is locked with the fixing frame by a threaded fastener, and the locking cover is provided with a limiting portion to prevent the cantilever from being screwed out of the positioning groove. Its structure includes a hollow protective cover, which protects the instrument to prevent external objects from colliding with the instrument and causing damage to the instrument, and prevents larger algae or other impurities from entering the instrument well. Although the ocean buoy is equipped with a hollow protective cover to protect the sensor, with long-term use, there will be more and more impurities on the sensor. If the sensor is not cleaned in time, it will affect the accuracy of the detection. The ocean buoy is large in size and complex in structure. It is too cumbersome to clean the sensor.
