Proximity switch water-cooling protection device in high-temperature environment

Abstract

The utility model discloses a proximity switch water-cooling protection device in a high-temperature environment, belongs to the technical field of protection equipment of signal detection components in the metallurgical industry, and is used for enabling a proximity switch to work normally in the high-temperature environment. According to the technical scheme, a water-cooling shell is a cube with a cavity in the middle, the side wall and the bottom face of the water-cooling shell are of a double-layer structure, circulating cooling water is poured into the double-layer structure, an upper cover is in closed connection with the upper end of the water-cooling shell, a transmission shaft hole is formed in the upper portion of the side wall of the water-cooling shell, and a transmission shaft is installed in the transmission shaft hole. The transmission shaft outside the water-cooling shell is connected with a vertically-placed shifting piece, the plate face of the shifting piece is perpendicular to the outer wall of the water-cooling shell, the transmission shaft inside the water-cooling shell is connected with vertical stop iron, the proximity switch is fixed in an inner cavity of the water-cooling shell, and the trigger end of the proximity switch is opposite to the stop iron. The proximity switch is simple in structure and convenient to use, the ambient temperature around the proximity switch can be remarkably reduced, and the purpose of using the proximity switch in a high-temperature environment is achieved.
