Environmental water quality monitoring device with alarm function

The utility model relates to the technical field of micro water quality monitoring stations, and discloses an environmental water quality monitoring device with an alarm function, which comprises a solar panel, a support frame is welded at the bottom of the solar panel, a U-shaped frame is fixedly arranged at the bottom of the support frame, and buoys are fixedly arranged on two sides of the U-shaped frame. Under the action of the buoy and the anchor block, the device floats on the river surface when the device runs, and meanwhile, the whole device can be stabilized at the same position to prevent the device from drifting along with river water, so that the stability of the device is improved. By means of the infrared emitter and the infrared receiver, when water flow is polluted, the alarm can give an alarm, and workers are reminded to further monitor the water quality. And through cooperative use of a U-shaped frame and an infrared emitter, the structure of the device is simpler, the manufacturing cost of t
