The present invention relates to a sensor device for water quality measurement, which is equipped with a self-cleaning means.

The present invention also relates to a sensor device for measuring water quality, which is equipped with a self-cleaning means and is provided with a self-generating means in a sensor device used in water, and which can operate in water without a separate power supply.

Underwater sensor devices are used to measure the quality of water such as rivers, lakes, reservoirs, and the sea. Such an underwater sensor device has turbidity, pH, dissolved oxygen,

Water quality measurement probes or sensors for measuring temperature, salinity and the like. However, when these water quality measurement probes or sensors are widely contaminated by plants and animal species such as fungal or seaweed growth, accurate measurement may be hampered or the operation of the sensor device itself difficult. Therefore, due to the contamination of such water quality measurement probes or sensors, it is necessary to maintain normal operation only for a predetermined period of time, and thereafter to perform maintenance or manual purification, thereby limiting the use of the sensor device. Furthermore, in the case of sensor devices used in highly polluted environments, existing sensors are not suitable for accurate measurement of contamination over a long period of time, because the accumulation of debris or fungal or seaweed growth on the sensor is caused in a short period of time.

Accordingly, there has been developed a cleaning wiper element disclosed in Korean Patent Laid-Open Publication No. 10-2005-0002859, a brush attached to an end of a wiper element, and a wiper for cleaning a water quality sensor and a brush device having a wiper drive motor 1 and Fig. 2).

On the other hand, an underwater sensor device used for measuring water quality of a river, a lake, a reservoir, and the sea requires a power source for driving data output means for transmitting the measured water quality information to the local control unit, Or power is supplied from the ground to the wire. However, in the case of incorporating a battery, since the battery usage limit is limited, the battery must be periodically replaced, and in the case of supplying power by wire, the apparatus becomes complicated due to electric wiring, and the cost is increased.

In order to solve such a problem, a buoy type self-generating robot disclosed in Korean Patent Laid-Open Publication No. 10-2013-0025490 has been developed.

However, the buoy type self-propelled robotic device includes a body for providing buoyancy in water and a power generator using solar light for self-power generation, which complicates the device and requires a high cost.
