[0002] An offshore drilling platform is an offshore structure used for drilling wells, mainly used for offshore oil and gas exploration. It can be fixed, movable or semi-submersible, and can house drilling equipment and provide a living place for staff. On an offshore drilling platform, there may be flammable and explosive gases or substances, such as oil, natural gas, etc. These gases are very likely to explode when encountering factors such as fire or static electricity. A positive pressure explosion-proof room is a room with explosion-proof function. It prevents external flammable and explosive gases from entering the room by maintaining a positive pressure in the room, thereby ensuring the safety of personnel and equipment in the room.

[0003] In the prior art, the positive pressure explosion-proof room usually fixes the bottom plate to the ground with rivets, and then fastens several side wall panels to the top plate with bolts, and then installs other necessary equipment. However, this installation method is not only troublesome, but also more time-consuming and labor-intensive to disassemble after the construction is completed. Therefore, the technology in the field proposes to use positive pressure explosion-proof rooms for offshore drilling platforms to solve the above problems. Utility Model Content

[0006] Furthermore, the protection assembly includes two fixing rings, the outer sides of the fixing rings are fixedly connected to the outer sides of the side plates, and the top of the drilling platform is fixedly connected with four fixing blocks.

[0007] Furthermore, a chain is fixedly connected to the outer side of the fixing ring, and one end of the chain is fixedly connected to one side of the fixing block.

[0008] Further, one side of the side plate is slidably connected to one side of the auxiliary block, and the other side of the side plate is slidably connected to the outer side of the bottom plate.

[0009] Furthermore, the outer side of the top cover is slidably connected to the outer side of the side plate, and the bottom of the top cover is fitted to the top of the side plate.

[0010] Furthermore, one end of the locking rod is fixedly connected with a pull ring, and the other end of the locking rod is engaged in the interior of the locking slot.

This is convenient for installation. When the whole is dismantled, the pull ring is pulled to extract the lock core from the inside of the card slot, which removes the restrictions between the side plate and the bottom plate, and the restrictions between the side plate and the top cover, and the whole structure can be easily dismantled.

[0015] 2. In the utility model, the inclined design of the fixed block can guide the sea breeze upward to a great extent to avoid blowing directly to the explosion-proof room body. The chain is used to reinforce the connection between the side plate and the fixed block, making the explosion-proof room more stable and not easy to collapse inward.
