Abstract
The utility model discloses a device for detecting spontaneous combustion of coal on a tipper wagon surface to be unloaded. The device for detecting the spontaneous combustion of the coal on the tipper wagon surface to be unloaded is mainly composed of an infrared temperature measurement sensor, a module of analog quantity converted into switching quantity, a stoppage trigger and an adjustable mounting bracket. The adjustable mounting bracket is mounted above a wagon prepared to be unloaded, wherein the wagon is arranged at the entrance of a tipper. The infrared temperature measurement sensor is mounted on the adjustable mounting bracket and is connected with the module of analog quantity converted into switching quantity to convert an analog quantity signal into a switching quantity signal. The module of analog quantity converted into switching quantity is connected with the stoppage trigger. The device for detecting the spontaneous combustion of the coal on the tipper wagon surface to be unloaded is accurate in detection and can effectively judge the coal on the tipper wagon surface layer prepared to be unloaded combusts spontaneously or has the trend of spontaneous combustion so as to immediately take effective fire preventing and extinguishing measures. Therefore, loss of resources, devices and life can be avoided, so that safe production is guaranteed.
Description
Technical field
The utility model relates to a kind of detecting device, relates in particular to a kind of for tipper epidermis layer to be unloaded spontaneous combustionof coal detecting device.
Background technology
The coal fire is one of major casualty of defeated coal harbour mouth.And spontaneous combustionof coal is the principal mode of defeated coal harbour mouth fire, and spontaneous combustionof coal not only causes direct economic loss, causes the large tracts of land disaster, also can produce a large amount of SO
2, H
2S, CO and CO
2Gas, serious environment pollution.
The static spontaneous combustionof coal detection technique of storing up for the stockyard has had relevant mature technology, but for the top layer spontaneous combustionof coal test problems with tipper railway carriage dynamic operation to be unloaded, also there is no fine solution.If tipper epidermis layer to be unloaded spontaneous combustionof coal detecting device can be arranged, just can judge whether to have spontaneous combustion or spontaneous combustion trend by detecting device, in order in time take actv. fire prevention, fire extinguishing measure, avoid causing even human loss of resource, equipment, guarantee safety in production.
Summary of the invention
The purpose of this utility model is to provide a kind of can accurately detect tipper epidermis layer to be unloaded spontaneous combustionof coal detecting device.
to achieve these goals, the technical solution of the utility model is as follows: a kind of for tipper epidermis layer to be unloaded spontaneous combustionof coal detecting device, mainly by infrared temperature-test sensor, analog quantity turns the switching value module, fault binary pair and adjustable installing bracket form, described adjustable installing bracket is arranged on place, tipper entrance railway carriage to be unloaded top, described infrared temperature-test sensor is arranged on adjustable installing bracket, described infrared temperature-test sensor turns the switching value module with analog quantity and is connected, the modulus signal is converted to the switching value signal that needs, described analog quantity turns the switching value module and is connected with the fault binary pair.
In described fault binary pair, rest-set flip-flop is set, i.e. fault latch mechanism.After analog quantity turned the switching value module breakdown signal is passed to the fault binary pair, this fault binary pair was with fault latch, and this fault latch mechanism sends reset signal and resets after Failure elimination.
By adjustable installing bracket, described infrared temperature-test sensor is fixed on place, tipper entrance railway carriage to be unloaded top, exactly in order to adjust infrared temperature-test sensor, makes its accurate location.
Described infrared temperature-test sensor is more than two covers or two overlap.If the first set infrared temperature-test sensor breaks down, just other infrared temperature-test sensor starts, guarantee the reliability of check.
the utility model working process is as follows: when tipper railway carriage coal surface to be unloaded temperature surpasses normal temperature, during by infrared temperature-test sensor, infrared temperature-test sensor can be converted into analog electric signal with temperature signal, then turn the switching value module by analog quantity the analog electric signal that receives is converted to the switching value signal, send switch actuating signals to the fault binary pair, hinder for some reason and be provided with rest-set flip-flop in binary pair, to input to the set end that RS triggers after the on-off signal conversion of receiving, with asserts signal latch after by rest-set flip-flop to breakdown signal of Control System for Tippler, notice tipper operator has spontaneous combustion coal and processes.After processing finishes, provide the failure reset signal, the fault triggering system resets latch signal, and the output point of fault binary pair no longer provides breakdown signal, and normal operation recovers in system.
The utlity model has following advantage: simple in structure, with low cost, detection is accurate, the energy actv. judge whether tipper epidermis layer to be unloaded coal has spontaneous combustion or spontaneous combustion trend, in order in time take actv. fire prevention, fire extinguishing measure, avoid causing even human loss of resource, equipment, guarantee safety in production.
