Infrared thermal image detection device

Abstract

The invention discloses an infrared thermal image detection device. The device comprises an infrared thermal imager, a shell, a first support and a distance adjusting structure. N preheating holes are evenly formed in the surface of the infrared thermal imager. A dry layer is disposed on the inner wall of the infrared thermal imager, an electric heating bar is fixed in the middle in the shell, a fan is fixed to the bottom in the shell, an air inlet in the lower end of an air collecting cover is connected with the open end of the shell, an air outlet in the upper end of the air collecting cover is connected with one end of an exhaust main pipe, the other end of the exhaust main pipe is connected with N exhaust branch pipes through a flow divider, and the other ends of the N exhaust branch pipes are connected with N air needles respectively. The distance adjusting structure comprises a motor, a gear, a rack, a first rod and a second rod. The device has the advantages of being reasonable in design, high in safety during detection of power equipment, high in preheating speed, good in effect and not likely to be affected with damp.

Description

technical field [0001] The invention relates to the research field of infrared detectors, in particular to an infrared thermal image detection device. Background technique [0002] The infrared thermal imager uses the infrared detector and the optical imaging objective lens to receive the infrared radiation energy distribution pattern of the measured target and reflect it on the photosensitive element of the infrared detector to obtain an infrared thermal image, which is consistent with the thermal image on the surface of the object corresponding to the distribution field. In layman's terms, an infrared thermal imager converts the invisible infrared energy emitted by an object into a visible thermal image. Different colors on the top of the thermal image represent different temperatures of the measured object. [0003] Infrared thermal imaging cameras are often used in the detection of electrical equipment. Infrared imaging of electrical equipment can quickly detect electr...
