The invention relates to an air-cooled high-temperature explosion-proof video camera. An inner sleeve of the video camera is arranged in an outer sleeve; a rear cover and a flange are fixed at one end of the inner sleeve and one end of the outer sleeve respectively; two locking nuts are connected with two wire inlet holes through two rubber rings respectively; a supporting plate is fixed with a front cover; one end of a lens protecting sleeve which is connected with a sheath lock nut is connected with one end of the front cover through the supporting plate; the other end of the front cover isconnected with the lock nut; an outer disk is fixed with the other end of a high-temperature lens protecting sleeve; one end of a high-temperature lens to which a positioning disk is fixed is arranged in the high-temperature lens protecting sleeve; the video camera is arranged in a video camera protecting sleeve; and the front cover is fixed with the flange. The video camera has the characteristics of guaranteeing stable work under a high temperature condition, along with forced cold air cooling, corrosion resistance and dust protection. The high-temperature explosion-proof video camera has the advantages of a normal high-temperature air-cooled video camera, has an explosion-proof design, is applied to an explosive dangerous place, is safer and more reliable and contributes to field installation and debugging.
