Water quality detection buoy

The utility model discloses a water quality detection buoy which comprises a floating rod, a floating body, an anti-grounding structure and a water quality detection sensor, the floating rod is inserted into water; the floating body is arranged at the top of the floating rod and floats on the water surface so as to provide buoyancy support for the floating rod; the water quality detection sensor is relatively fixedly mounted on the floating rod and floats up and down along with the lifting of the water level along with the floating rod; the grounding prevention structure is arranged at the bottom of the floating rod, extends downwards and exceeds the bottom end of the water quality detection sensor so as to prevent the water quality detection sensor from grounding. The water quality detection buoy provided by the utility model is accurate in water quality detection and high in safety. 本实用新型公开了一种水质检测浮标，包括浮动杆、浮体、防触底结构和水质检测传感器；浮动杆插入水中；浮体设置于浮动杆顶部并浮于水面，以对浮动杆提供浮力支撑；水质检测传感器相对固定安装于浮动杆上，水质检测传感器跟随浮动杆随水位升降而上下浮动；防触底结构设置于
