Description

Technical Field

[0001] The utility model relates to a safety gas filling station door for large ships, belonging to the technical field of ships. Background Art

[0002] Gas ships need to go through gas stations to replenish natural gas for other ships. The natural gas pipeline is sent to the natural gas inlets of other ships through the gas station door. However, the current gas station door does not have a fireproof device. Once an open flame appears near the gas station door, it is necessary to take out the fire-fighting equipment from the cabin behind the gas station door and extinguish the fire manually. The manual fire-fighting method is not only inefficient, but also easily delays the fire-fighting time, resulting in natural gas hazards and causing greater safety accidents. Utility Model Content

[0003] The utility model aims to overcome the above-mentioned shortcomings and provide a safe gas station door for large ships, which can quickly extinguish fire and avoid accidents.

[0004] The purpose of the utility model is achieved in this way:

[0005] A safe gas station door for large ships comprises a platform device, which is a hollow structure, with an outer panel on the front and an inner panel on the back. Inner lining panels are installed on both sides of the platform device, and a water spray main pipe is passed between the inner lining panel and the inner panel. Both ends of the water spray main pipe are connected to a water inlet pipe through an adapter, and the water inlet pipe passes through the platform device and is connected to an external fire hose. A plurality of branch pipes are arranged in the middle of the water spray main pipe, and the branch pipes are perpendicular to the water spray main pipe, and the ends of the branch pipes are exposed from the inner panel. The platform device is hinged to the frame door of the hull cabin through a hinge mechanism.

[0006] The platform device forms a door panel of the gas filling station when folded up, and forms a platform for placing natural gas pipelines when folded down.

[0007] A plurality of reinforcing ribs are arranged between the outer panel and the inner panel from top to bottom.

[0008] The terminal opening of the branch pipe is lower than the surface of the inner panel.

[0009] The utility model provides a safe gas station door for large ships, which has the following advantages:

[0010] This type of safe gas station door for large ships is achieved by setting a mezzanine between the inner and outer panels of the platform, in which a water spray pipe is placed. After the platform is lowered, the water spray pipe can spray water to the natural gas pipeline above to extinguish the fire, thereby eliminating the need to remove fire-fighting equipment from the cabin, improving fire-fighting efficiency and avoiding safety accidents.

[0014] In the figure: platform device 1, outer panel 2, inner panel 3, reinforcing rib 4, lining board 5, water spraying main pipe 6, water inlet pipe 7, fire hose 8, hinge mechanism 9. Specific implementation mode

[0015] As Figures 1 to 3 , the present utility model relates to a safety type gas filling station door for a large ship, including a platform device 1. When the platform device 1 is retracted, it forms the door panel of the gas filling station, and when it is lowered, it forms a platform for placing natural gas pipelines. The platform device 1 is a hollow structure, with the front being the outer panel 2 and the back being the inner panel 3. A plurality of reinforcing ribs 4 are arranged vertically from top to bottom between the outer panel 2 and the inner panel 3.

[0016] On both sides inside the platform device 1, lining boards 5 are installed. A water spraying main pipe 6 passes through between the lining board 5 and the inner panel 3. Both ends of the water spraying main pipe 6 are connected to the water inlet pipe 7 through adapters. The water inlet pipe 7 passes through the platform device 1 and is connected to the external fire hose 8. There are a plurality of branch pipes in the middle of the water spraying main pipe 6. The branch pipes are perpendicular to the water spraying main pipe 6, and the ends of the branch pipes protrude from the inner panel 3 to spray water externally. The ends of the branch pipes are slightly lower than the surface of the inner panel 3, so as to avoid knocking and bumping.

[0017] The platform device 1 is hinged to the frame door of the ship's cabin through a hinge mechanism 9. Through the hinge mechanism 9, the platform device 1 is slowly lowered or retracted, and finally forms a platform for placing natural gas pipelines or the door panel of the gas filling station.
