Infrared correlation detection type longitudinal tearing sensor

Abstract

The invention relates to the technical field of detection, in particular to an infrared correlation detection type longitudinal tearing sensor. The sensor comprises a first elastic bag, a second elastic bag, a connecting rod mechanism, infrared laser transmitters and an infrared imager; the infrared laser transmitters are arranged at the left end of the inner bottom of the second elastic bag at intervals in the left-right direction, and the infrared imager is arranged at the right end of the inner bottom of the second elastic bag; a conveyor belt extrudes the first elastic bag downwards aftergenerating deformation protrusions, then extrudes the second elastic bag downwards to enable the second elastic bag to deform, light emitted by the infrared laser transmitters changes a reflection path to reach the position outside the receiving range of the infrared imager, and the size of the first elastic bag is increased after the first elastic bag is extruded each time, therefore, the deformation of the second elastic bag is accumulated. According to the invention, abnormal changes caused by tiny deformation protrusions are repeatedly accumulated in the conveying process of the conveyingbelt, and therefore the conveying belt can be found in time when being about to be torn longitudinally and damaged.

Description

Technical field [0001] The present invention relates to the field of detection, and more particularly to an infrared-to-episode detection type longitudinal torn sensor. Background technique [0002] Multi-purpose belt conveyor assist transportation in coal mining, production, tranout, processing, the coal mine belt conveyor has the characteristics of high transportation, complex working environment, strong load capacity, and long transportation distance, conveyor belt as a coal mine belt The main load of the conveyor is very likely to occur, and therefore, the tape conveyor should be installed in the direction of the coal flow direction (when the belt conveyor is head driving) at the direction of the conveyed coal flow. Tear detection device. [0003] In the prior art, the tear detection of the conveyor belt is made in a variety of ways, for example, the application number: 201610722297.1, the authorization notice number is: CN 106185240 B China Patent Document discloses an infra...
