Water quality sensor anti-blocking device

Abstract

The utility model discloses a water quality sensor anti -blocking device relates to water quality monitoring equipment technical field, include: the protection cover, one end is used for connecting high pressure water source, the connecting pipe is fixed on the one end of protection cover away from high pressure water source, one end of connecting pipe is used for connecting water quality sensor, spherical filter screen is fixed in the one end of connecting pipe away from water quality sensor for filtering impurity, a plurality of flow guide rings are along the inner wall of protection cover, when high pressure water source is connected, a plurality of flow guide rings gradually reduce the inside circulation diameter of protection cover in proper order, and the water flow is reflected and obliquely impacts the backwater surface of spherical filter screen, can strongly clean the impurity that adheres on the backwater surface of spherical filter screen, prevents the impurity and piles up and blocks on the spherical filter screen, owing to the reduction of inside circulation diameter of protection cover, can also make the cleaning effect better.
