Water resource pollution monitoring device

The invention discloses a water resource pollution monitoring device in the technical field of water resource monitoring. The water resource pollution monitoring device comprises a floating block body, and a plurality of pushing mechanisms used for pushing the floating block body are arranged in the circumferential direction of the floating block body; the floating block body is further provided with a sampling mechanism, a lifting tank is arranged below the floating block body, a control panel is fixedly connected into the lifting tank, and the lifting tank is communicated with a lifting mechanism used for controlling the lifting tank to move up and down in water. The control panel compares water quality data measured by the water quality sensor with a set standard cone value, if the water quality data is smaller than the set standard cone value, the operation is stopped, and if the water quality data is larger than the set standard cone value, the control panel starts the sampling mechanism to sample the wa
