In a link for making a precision mold, the temperature of each point site of the mold needs to be detected, so as to meet the performance requirement of precision casting. The temperatures of these special positions need to be monitored. However, the camera that is used currently cannot effectively block the dust at the construction site and isolate the high temperature, resulting in abnormal work of the camera, and the service life of the internal device of the camera is affected due to heating. Therefore, a camera capable of resisting high and low temperatures, dedusting, cleaning and protecting splashes is necessary, so as to meet the monitoring needs in a special case.
[0003] The technical problem to be solved by the present disclosure is to provide an industrial, air-cooled, duct-proof and protective type thermal imaging camera, which can block dust and run normally under a high temperature environment, so as to meet the monitoring needs in a special case.

Cold air, entering from the air inlet, is discharged from the air outlets after flowing through the annular and spiral air duct, so that the double-layer protective shield can block the external high temperature. Due to the spiral air duct design, the heat can be exported effectively through the air flow, so that the temperature in the barrel is kept in the working temperature range of the camera, and the normal running of the camera at the high temperature 2
BL-5674 environment is ensured. The air directions of the air outlets face the position at the side of the PONTS round glass through the dust blocking device - dust board that is at the front end of the barrel, so that the dust is not easy to collect on the round glass shield, and the dust in the operation area can be blocked effectively, so as to ensure that the dust does not fall on the lens glass. Or the dust blocking device - protective door at the front end of the barrel can be opened and closed according to the setting logic under the control of a background PLC (Program Logic Control), which not only enables the camera to implement interval monitoring, but also blocks the dust in the operation area, so as to ensure that the dust does not fall on the lens glass. An internal thermal imaging camera can perform alarm detection on an abnormal high temperature in a monitoring area. In the present disclosure, the camera can meet the monitoring needs in the special environment by blocking the dust and high temperature.
