Description

Technical Field

[0001] The utility model relates to the technical field of fireproof ventilation pipes, in particular to a fireproof ventilation pipeline for ships. Background Art

[0002] Fire-resistant duct is a kind of duct used in the ventilation system inside a building. Its main function is to convey air to maintain indoor air quality. Unlike ordinary ducts, fire-resistant ducts have fire-resistant properties in design and material selection, which can resist the spread of fire and protect the safety of people and property inside the building.

[0003] The design and manufacture of fireproof air ducts need to comply with relevant building fire protection standards and specifications. Common fireproof air duct materials include fire-resistant boards, fire-resistant fiberglass, fire-resistant insulation materials, etc. These materials have certain thermal insulation and fire-resistant properties and can delay the spread of fire when a fire occurs.

[0004] The ship's fireproof ventilation ducts use fireproof air ducts to establish ventilation paths inside the cabin. Since the space inside the cabin is small, even if the fireproof ventilation ducts can delay the spread of fire, they cannot prevent the spread of smoke, which may cause suffocation in the cabin.

[0010] By providing the card slots and the protrusions, when two fireproof ventilation pipes are connected, the positions of the two fireproof ventilation pipes can be limited by means of a plurality of protrusions respectively engaging in the card slots. Thereby, the positions of the limiting slide grooves of the two adjacent fireproof ventilation pipes can correspond to each other, so that the smoke detector can be better pushed to a deeper position for use.

When the two fireproof ventilation pipes 6 are connected, the positions of the two fireproof ventilation pipes 6 can be limited by the plurality of protrusions 22 respectively engaged in the card slots 21 so that their corresponding positions can match. When the straight pipe distance in the fireproof ventilation duct is long and includes a plurality of fireproof ventilation pipes 6, the positions of the limiting slide grooves 10 of the two adjacent fireproof ventilation pipes 6 can be made corresponding by limiting the protrusions 22 and the card slots 21, so that the smoke detector 16 can be better pushed to a deeper position for use.

[0024] Reference Figure 4 In a preferred embodiment, the top inner wall of the fireproof ventilation pipe 6 at the top is fixedly connected to a three-way pipe 4, and the outer wall of the three-way pipe 4 is fixedly connected to a support shell 3, and the bottom inner wall of the support shell 3 is fixedly connected to two cylindrical brackets 29.

[0025] Reference Figure 4In a preferred embodiment, the two cylindrical brackets 29 are respectively connected to the two ends of the three-way pipe 4, and the two cylindrical brackets 29 are respectively provided with a ventilating fan 30, and the wind directions of the two ventilating fans 30 are oppositely arranged.
