Abstract

This utility model discloses a device for detecting the uniformity of fire-retardant coatings in power engineering, relating to the field of coating testing technology. It includes a mounting block with a through groove inside, a sliding groove in the middle of the through groove, a T-shaped slide rail inside the through groove below the slide rail, and a T-shaped slider inside the mounting block that slides along the T-shaped slide rail. A movable measuring block is mounted on the side of the T-shaped slider, and an adjustment mechanism is installed inside the measuring block. Two sets of detachable induction probes are mounted at the bottom of the measuring block, and measuring rulers are mounted on both sides of the measuring block outside the measuring block. A touch-screen control panel is mounted on the top of the mounting block, and an adsorption mechanism is mounted at the bottom of the mounting block. This utility model improves measurement accuracy, reduces operational difficulty, and enhances adaptability, providing a more reliable, efficient, and convenient tool for detecting the uniformity of fire-retardant coatings in power engineering.
