Abstract

The utility model discloses a height detecting mechanism of a liquid level. The height detecting mechanism of the liquid level comprises a fixed base and a servo motor. The servo motor is assembled with a ball screw which is connected with a power output shaft of the servo motor through a coupler. The fixed base is provided with a ball nut which is matched with the ball screw, and the a movable installation board which can not vertically move relative to the servo motor is arranged below the fixed base. An electric wood block is arranged on the lower surface of the movable installation board, and a liquid level probe is arranged below the electric wood block. According to the height detecting mechanism of the liquid level, the height of the liquid level is measured mainly through the moving distance of the liquid level probe. When the height detecting mechanism works, the servo motor drives the movable installation board to downwards move through matching of the ball screw and the ball nut. When the liquid level probe touches the liquid level and is conducted with the liquid level, the servo motor stops acting, and the liquid level probe stops downwards moving. The height detecting mechanism of the liquid level is capable of automatically and accurately detecting the height of the liquid level of liquid with conductivity and has the advantages of being high in automation degree, wide in application range and high in measuring precision.
