When the buoy is stably floating on the water surface, the driving motor is started, the lifting rope is released through the rotating shaft, the counterweight and anchor rod fall into the riverbed under the action of gravity, the anchor rod is inserted into the silt, which enhances the stability of the buoy and reduces the influence of wind waves and water flow disturbance on the position of the buoy.

[0011] Method of use: The user first places the device in the river channel to be monitored. Under the action of the floating ball, the floating plate will float on the water surface. At this time, the monitoring end of the monitoring sensor enters the water body and starts to monitor the heavy metals in the water body. The monitoring data will be fed back to the terminal by the control unit and displayed.

[0012] When the floating plate is stably floating on the water surface, the person starts the general motor, the general motor starts to operate and drives the winding rope rotating shaft to rotate, the lifting rope on the surface of the winding rope rotating shaft starts to be unwound after the winding rope rotating shaft rotates, in the process of unwinding the lifting rope, the counterweight and the anchor rod move downward under the action of gravity and finally fall into the riverbed, after the counterweight and the anchor rod fall into the riverbed, part of the counterweight will sink into the silt in the riverbed, and the anchor rod will be inserted into the silt, this state can effectively limit the activity range of the floating plate, so that the floating plate will not deviate from the pre-set monitoring point due to the impact of wind waves, water flow disturbance and the like, the device can stably and effectively float on the water body, and continuously monitor the heavy metals in the water body in the specified area.
