Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0014] combine figure 1 , the structure of the infrared temperature measuring endoscope of the present invention includes: an infrared thermal imaging core 1, an infrared filter 2, a filter fixing ring 3, an endoscope housing 4, a cover 5, a mounting threaded pipe 6, and a pagoda joint 7 , Water-cooling cavity 8, air-cooling slot 9, wiring opening 10, screw mounting hole 11, fluorine rubber O-ring 12.

[0015] The endoscope housing 4 forms an annular water-cooling cavity 8 in the middle of the double-layer housing. The upper end of the endoscope housing 4 is provided with a cover 5, which is sealed and connected with the endoscope housing 4 by screws. The bottom of the endoscope housing 4 The end protrudes downwards and is provided with a mounting threaded pipe 6 for connecting to other combustion chamber cavities or high-temperature and high-...

Abstract

The invention discloses a portable low-cost pressure-resistant and temperature-resistant infrared temperature measuring endoscope comprising an endoscope shell, an infrared thermal image machine coreand an infrared filter; a cover is arranged on the upper end of the endoscope shell, the bottom end of the endoscope shell is downwardly-projected and is provided with a mounting threaded pipe, the mounting threaded pipe is connected into other cavities through threads, an infrared thermal image machine core lens is embedded downwardly in the inner cavity of the endoscope shell, the infrared filter is arranged in front of the infrared thermal image machine core lens, and is fixed through a filter fixing ring, a water cooling cavity is formed in the endoscope shell, an air cooling open groove is formed in the endoscope shell and is used for blowing nitrogen or other inert gas into the infrared filter, and the infrared filter is prevented from being overheated and damaged. The whole endoscope can be conveniently mounted and fixed on the surface of an object to measure the internal temperature and the thermal image. The temperature measurement of the internal structure of the object underhigh-pressure high-temperature environment is realized, the whole device is small and light, easy to operate, convenient to carry and low in cost.

Description

technical field [0001] The invention relates to an infrared temperature-measuring endoscope, in particular to a portable low-cost pressure-resistant and temperature-resistant infrared temperature-measuring endoscope. The device can ensure that a precise infrared camera can work normally in a high-temperature and high-pressure working environment. Background technique [0002] The infrared endoscopes currently used are mostly used in the fields of industrial production and equipment monitoring. For example, infrared probes are installed in electrical equipment control cabinets to prevent accidents by monitoring the temperature. And it is used in the steel production process to improve the quality of steel by better monitoring the temperature in the production process. [0003] There are many limitations in the application of infrared cameras now, because the lenses of the cameras are more precise and cannot withstand high temperature and high pressure in certain working envir...
