Closed strip-shaped coal yard monitoring device

Abstract

The invention relates to a closed strip-shaped coal yard monitoring device, and belongs to the technical field of coal storage. The closed strip-shaped coal yard monitoring device comprises a coal stocktaking device arranged on the edge of one side of a coal pile; the coal stocktaking device comprises a mounting frame, a laser coal measuring instrument and a plurality of rails fixed on the ground and arranged in the length direction of the coal pile; a power motor is fixed on the mounting frame, and an output shaft of the power motor is fixedly sleeved with a power bevel gear; an axle is fixed on the mounting frame, the axle is sleeved with sliding wheels with the same number as tracks, the sliding wheels are in rolling connection with the tracks in a one-to-one correspondence mode, and the axle is further fixedly sleeved with a shaft bevel gear meshed with the power bevel gear; and a cantilever is connected to the mounting frame, the free end of the cantilever is arranged close to the coal pile, and the laser coal measuring instrument is fixed to the cantilever and electrically connected with an upper computer. The device is high in controllability and accurate in measurement result, and can perform temperature detection on coal seams with different depths in a coal seam to prevent spontaneous combustion of the coal pile.

Description

technical field [0001] The invention relates to a monitoring device for a closed strip coal yard, which belongs to the technical field of coal storage. Background technique [0002] In the operation of the coal yard of a coal-fired power station, the amount of coal stored and the temperature of each area are the two sets of data that operators are most concerned about. amount of coal. At present, the amount of coal stored in the coal yard of coal-fired power stations is generally measured by the laser pan coal instrument system, and the temperature of each area of ​​the coal pile is generally obtained by the infrared thermometer system. [0003] The working principle of the laser coal pan instrument is: use a high-precision laser to scan the surface of the coal pile on the coal yard, collect surface shape information at the same time, and then synthesize it into a three-dimensional coal pile shape through computer processing, so as to obtain the volume of the coal pile.
