The invention discloses a fire hazard preventing type offshore drilling platform which comprises an upper-layer platform and a lower-layer platform. A derrick is arranged at the top of the upper-layer platform, a crane is arranged on one side of the derrick, four guide pile pipes are arranged at the bottom of the lower-layer platform, pile pipe are arranged at the bottom ends of the guide pile pipes, and an air guide pipe is transversely arranged between the upper-layer platform and the lower-layer platform; a plurality of through holes are evenly formed in the upper-layer platform, the air guide pipe and the through holes are connected through a draught fan, and air outlet pipes are arranged at the two ends of the air guide pipe; a water pump installation frame is arranged on one sides of the guide pile pipes, a water pump is arranged on the water pump installation frame, a water drawing opening is formed in one end of the water pump, and the other end of the water pump is communicated with one end of a water pipe; and the water pipe is communicated with spraying heads through a plurality of branched water pipes. According to the device, comprehensive fireproofing facilities are arranged on the drilling platform, seawater can be drawn for fire fighting; and in addition, the bottom face can achieve the air suction function when a fire hazard happens, harmful gas is quickly sucked away, and rescue time is won for people.
