A device for measuring flow rate and water quality for a river is disclosed.
The present invention disclosed is a pickup electric winch for winding or unwinding a pickup rope according to a control signal of a first controller while being installed on a structure of a river or at the edge of the river; A docking station including a traction electric winch which is connected to an end of the pickup rope and is anchored in a floating state on the water surface of the river and winds or unwinds the traction rope according to a control signal from a second controller; And it is connected to the end of the traction rope, while crossing in the width direction of the river in a state separated from the docking station, unmanned movement measuring body for measuring measurement values such as flow rate, water quality, and similar amount of the river; including, but unmanned movement measuring body The automatic crossing in the width direction of the river while maintaining a state separated from the docking station by the length of the unwinded towing rope by the flow of the river, drawing an arc trajectory around the docking station by the automatic crossing means. It is characterized in that to measure the measured value.
Since the present invention is capable of unmanned measurement, it is possible to measure 24/7 unless there is a special weather change, and it is possible to prevent safety accidents and reduce measurement cost.
In addition, measurement accuracy is high by measuring several locations while crossing a river, and maintenance cost can be reduced because it is mainly operated using natural energy.
In addition, the equipment can be protected from danger by winding the towing rope and the pickup rope to escape from the danger area in case of bad weather information and an emergency situation.
