A screen display portable explosion-proof searchlight

Abstract

The utility model relates to the technical field of explosion-proof searchlights, and proposes a screen-display portable explosion-proof searchlight. When the explosion-proof lamp is finished lighting work, residual heat will still remain on the surface of the explosion-proof lamp and the explosion-proof glass plate. At this time, the staff unscrews the protective cover from the first thread, and completes the thread connection work with the second thread through the screw groove on the inner wall of the protective cover. The protective cover can effectively prevent the user from contacting the explosion-proof glass plate when wearing it and thus causing the possibility of being scalded. At the same time, when the protective cover is screwed into the searchlight body along the second thread through the screw groove, the heat sink layer located on the inner side of the protective cover contacts the explosion-proof glass plate and completes the rapid conduction of heat. At the same time, the motor is started to make the fan rotate synchronously and quickly discharge the heat transferred from the heat sink layer in the protective cover from the filter screen. Through this design, the explosion-proof glass plate and the explosion-proof lamp can be quickly cooled.
