Description

Technical Field

[0001] This utility model relates to the field of marine pipeline technology, and in particular to a fire-resistant penetration device for marine pipelines. Background Technology

[0002] On ships, various pipelines need to pass through bulkheads or decks to ensure the flow of gas and liquid in all areas of the hull. However, if the pipelines are not fire-sealed after passing through bulkheads or decks, it will seriously affect the ship's watertightness and fire resistance, making it difficult for the ship to meet the basic requirements of anti-sinking design and fire safety.

[0003] According to the traditional sealing process, when filling the packing material, leakage of the packing material is likely to occur at the bottom, which can easily cause pollution to the machines below and the ground. At the same time, it will cause the packing material to be wasted. In addition, there are unfilled spaces between the protective pipe and the pipeline, and inside the pipeline. Once a collapse occurs, water or flue gas will inevitably enter or spread, causing safety hazards. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a fire-resistant penetration device for marine pipelines.

[0005] This utility model is achieved by the following technical solution: a fire-resistant penetration device for marine pipelines, including a deck, a plastic pipe is installed inside the deck, a flame-retardant expansion fireproof strip is fixedly connected to the surface of the plastic pipe, and a flame-retardant expansion fireproof sealing plug is sleeved on the surface of the plastic pipe.

[0006] Through the above technical solution, the deck, as the basic structure of the entire device, supports and fixes other components, providing a stable platform to ensure the structural integrity of the device. It works collaboratively with other components to jointly construct a fire barrier. The main pipeline for transporting media (such as water and oil) is made of plastic pipe. Compared to metal pipes, plastic pipes are lightweight, corrosion-resistant, suitable for marine environments, and have a smooth surface, reducing media transmission resistance and improving efficiency. Flame-retardant intumescent fireproof strips are wrapped around the surface of the plastic pipes, contacting the inner wall of the steel casing. Under normal conditions, they provide initial sealing and moisture protection. When exposed to high temperatures, the fireproof strips rapidly expand, blocking the gaps between the steel casing and the plastic pipes, preventing the spread of flames and high-temperature gases, and improving the system's fire resistance. Flame-retardant intumescent fireproof sealing plugs are fitted onto the surface of the plastic pipes and placed inside the steel casing. Two plugs are installed, normally providing a seal to prevent liquid and gas leakage. Under high-temperature conditions, the sealing plugs expand, more tightly filling the gaps between the steel casing and the plastic pipes, forming an effective fire barrier and preventing the spread of flames.

[0007] As a further improvement to the above solution, a steel sleeve is fixedly connected to the inner wall of the deck, and a plastic tube is installed inside the steel sleeve. The inner wall of the steel sleeve is in contact with the surface of the flame-retardant, expandable, fireproof sealing plug. Two flame-retardant, expandable, fireproof sealing plugs are provided, and the surface of the flame-retardant, expandable, fireproof strip is in contact with the inner wall of the steel sleeve.

[0008] Through the above technical solution, the steel sleeve is fixed to the inner wall of the deck, surrounding the plastic tube, providing additional physical protection, enhancing the overall structural strength of the device, and improving fire resistance when used in conjunction with the flame-retardant inflatable fireproof sealing plug and the flame-retardant inflatable fireproof strip.

[0009] As a further improvement to the above solution, the bottom of the deck is fixedly connected to the top of the insulation layer.

[0010] Through the above technical solution, the insulation layer is fixedly connected to the bottom of the deck, reducing the ingress of external heat and protecting the underlying structure from high temperature. The minimum thickness is mm, providing good heat insulation effect and extending the fire resistance time of the device.

[0011] As a further improvement to the above solution, the surface of the plastic tube contacts the inner wall of the clamp, two clamps are provided, the inner walls of the two clamps are threadedly connected to the surface of the bolts, and several bolts are provided.

[0012] Through the above technical solution, two clamps are installed on the surface of the plastic pipe, which are used in conjunction with bolts to ensure a firm connection between the plastic pipe and the steel sleeve, prevent loosening, facilitate installation and disassembly, and improve maintenance convenience. Several bolts are installed to connect to the inner wall of the clamps with threads, which strengthens the fixing effect of the clamps and ensures the long-term reliability of the device. By adjusting the bolts, the tightness of the clamps can be finely adjusted to ensure the sealing and stability of the device.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention utilizes a flame-retardant, expanding fireproof sealing plug to provide initial sealing under normal conditions, preventing the penetration of moisture and gas. When the temperature rises to a certain threshold, the chemical substances inside the sealing plug react, rapidly expanding in volume and more tightly filling the gap between the steel sleeve and the plastic tube, forming an effective fire barrier that prevents the conduction of flames and high temperatures.

[0015] Similar to flame-retardant intumescent fireproof belts, fireproof belts also expand at high temperatures, further enhancing the sealing effect. Their presence not only strengthens fire resistance but also improves the overall airtightness and watertightness of the structure, preventing the spread of smoke and toxic gases generated by a fire through pipes.

[0016] This invention provides additional thermal insulation through an insulation layer, slowing down the conduction of heat from the fire area to other areas. An insulation layer with a minimum thickness of mm can significantly reduce temperature transfer efficiency, protecting the underlying structure from high-temperature damage.

[0017] The combination of clamps and bolts ensures the tightness and stability of the entire device. By adjusting the bolts, the clamps can be firmly fixed to the plastic tube, preventing loosening due to vibration or other external forces, thus maintaining the long-term reliability of the device.
