Document Type and Number:
WIPO Patent Application WO/2020/098111
Kind Code:
A1
Abstract:
Disclosed is a mine radar level monitoring device, comprising a mine intrinsically-safe radar level sensor for detecting the level of a coal bin in real time, mine intrinsically-safe radar level display boxes for receiving and processing a signal detected by the mine intrinsically-safe radar level sensor, and mine flameproof intrinsically-safe direct-current voltage-stabilized power supplies, the mine intrinsically-safe radar level sensor being mounted above the coal bin; the mine intrinsically-safe radar level display boxes each comprise a box body, a box cover mounted on the box body, a main board mounted in the box body, and a display window mounted on the box cover, a first waterproof joint and a fifth waterproof joint respectively being mounted on the left side and right side of the box body, and a second waterproof joint, a third waterproof joint, and a fourth waterproof joint being mounted on the front side of the box body sequentially from the left to the right. The present invention improves the accuracy of dynamic detection of the level of a coal bin, and has good flameproof performance.
