[0002] A marine flame detector is a fire detection device specifically designed for marine environments (such as ocean-going ships, offshore oil platforms, etc.). The marine flame detector detects fires by detecting the flame spectral characteristics, light intensity, and flicker characteristics generated during the combustion of substances during a fire. It can timely detect potential fire hazards in the complex marine environment and provide an important guarantee for the fire safety of marine facilities. Marine flame detectors are widely used in the engine rooms and living areas of ocean-going ships, as well as above oil processing equipment, at the edges of platforms, and in areas vulnerable to fires on offshore oil platforms. They play an important role in fire warning in these places, helping to timely detect and handle potential fire hazards and ensuring the safe operation of marine facilities.
[0003] In the prior art, although the marine flame detector can detect and alarm potential fire risks by detecting the flame spectral characteristics, light intensity, and flicker characteristics generated during the combustion of substances during a fire, ignition sources (such as open flames caused by fuel leakage) may be generated during marine operations. After these ignition sources are detected, the high temperature of the ignition source may cause damage to the marine flame detector, and there is a lack of protective measures on the marine flame detector to isolate the high temperature of the ignition source. Therefore, an ignition protection device for a marine flame detector is now proposed. Summary of the Invention
