<p>According to an embodiment of the present invention, a sensor apparatus for water quality measurement having a self-cleaning means comprises an inner housing (10) having an upper tank (12), a lower tank (13) and a pump (14) therein, wherein the upper tank (12) and the lower tank (13) communicate with each other by a circulation pipe (11) and the pump (14) is arranged adjacently to the upper tank (12) or the lower tank (13) and circulates fluid in the circulation pipe (11); a rotary body (40) which is arranged on the outside of one side end of the inner housing (10) to be coupled to an input shaft (14a) of the pump (14) and is rotated by the flow of water to actuate the input shaft (14a); at least one sensor probe (16) mounted on the outside of the other side end of the inner housing (10); an outer housing (20) into which the inner housing (10) is inserted and coupled to be slid; and a support (30) supporting both sides of the outer housing (20) in order to allow a combination of the outer housing (20) and the inner housing (10) to move up and down. Furthermore, at least one penetrating hole (22) through which the sensor probe (16) can pass is formed on the end (21) of the outer housing (20) arranged on the side of the sensor probe (16) of the inner housing (10). According to the present invention, in the case of using the sensor apparatus having the self-cleaning means, the present invention can obtain effects of automatically cleaning a sensor part by a simple structure and operating the sensor apparatus without a separate power supply, thereby accurately measuring water quality for a long period of time.</p> |
