METHOD OF DETERMINING DEGREE OF DAMAGE OF SILAGE HOUSING OF ELEVATOR OF PRECAST REINFORCED CONCRETE Russian patent published in 2014 - IPC G01N25/72 

FIELD: agriculture.

SUBSTANCE: invention relates to food and flour and elevator industry and is used to assess the degree of damage of the joints of the outer silage of the elevator of precast reinforced concrete. According to the inventive method the thermal imaging device with a sensitivity of ±0.1°C and wavelength of 2-12 micron is mounted at a distance of 1-100 m from the surface of the elevator at an angle of 20° with positive outdoor temperature and the temperature difference between the inside and outside of the silage of at least 4°C. Then the thermal imaging recording of the outer surface of the silage housing is carried out. Then the results of thermal imaging recording are processed on the computer and the thermal imaging report is obtained according to which the maximum and minimum temperature on the surface of outer walls of the silage housing of the elevator are determined, and the difference of the said temperatures is calculated. The location and degree of damage of the joints of the outer silage of the elevator is determined according to the said method.

EFFECT: improved accuracy and informativeness of the obtained information about the defects of the joints of the outer silage of the elevator of precast reinforced concrete.
