DETECTOR MOUNTING BRACKET

The present invention relates to a detector fixed bracket for fixing and supporting a detector in a closed space of an offshore plant. The present invention includes a fixing unit which is installed in an installation hole formed on one side of the closed space, and an installing unit on which the detector is installed, and which is hinge-combined to the fixing unit, and protrudes a sensing unit of the detector to the outside by rotating around the hinge. The present invention performs a corresponding work without supporting the detector using hands or a body, by rotating the installing unit in which the detector is installed, around the hinge during the maintenance of the detector and correction of a sensor, on one side of the closed space. The present invention increases the stability of the work and the speed of the work and provides work which a user is able to perform by oneself, during the maintenance of the detector and the correction of the sensor.
