Automatic water area pollution source detection device

The invention discloses an automatic water area pollution source detection device. The device comprises a body, as well as a control unit, a driving unit, a sampling unit and a sensing unit, which are arranged on the body, wherein the sensing unit is used for acquiring direction and water quality information; the driving unit is used for driving the body and each unit carried on the body to be conveyed to a target direction on a water area; the sampling unit is used for water quality sampling; the control unit is used for controlling a water quality information acquisition time interval of a water quality sensor, comparing and analyzing the water quality information acquired by the water quality sensor, storing the direction and water quality information, determining a position of a pollution source, controlling the movement of the driving unit and controlling the sampling operation of the sampling unit. The device can automatically cruise in the water area, and can be used for automatically searching and positioning the pollution source of the water area without manual operation and bringing a sample back; the device can reach a water area which is difficult for a person to reach or highly dangerous; the water quality condition of a large water area can be automatically monitored and detected in real time, and a specific water area pollutant concentration can be provided.
