[0040] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0041] Figure 1 Schematic diagram showing the installation of the fire-proof penetration device provided by the embodiment of the present invention in the fire-resistant partition wall. Figure 1 This embodiment provides a fire-proof penetration device and a vessel. The vessel includes a heat source piping system and a fire-resistant bulkhead 10, as well as the fire-proof penetration device provided in this embodiment. The fire-resistant bulkhead 10 has a through hole 11 formed therein, and the fire-proof penetration device is installed in the through hole 11. The heat source piping system extends through the fire-proof penetration device.

[0042] The fireproof penetration device includes a mounting pipe 100, a mounting mechanism 200, a circulation mechanism 300, and an elastic mechanism 400. The mounting pipe 100 is installed in a through-hole 11 of a fire-resistant bulkhead 10 of a ship, and the mounting mechanism 200 is connected between the peripheral side of the mounting pipe 100 and the fire-resistant bulkhead 10. The mounting pipe 100 provides external protection for the circulation mechanism 300, and the mounting mechanism 200 ensures the secure installation of the mounting pipe 100 in the through-hole 11.

[0043] The circulation mechanism 300 extends through the mounting pipe mechanism 100 and is configured to allow the heat source piping to pass through. The two ends of the circulation mechanism 300 can be connected to the portions of the heat source piping located on either side of the fire-resistant bulkhead 10. The elastic mechanism 400 is disposed between the mounting pipe mechanism 100 and the circulation mechanism 300. The circulation mechanism 300 is capable of stretching or compressing along its axis, and the elastic mechanism 400 is capable of expanding and contracting along its axis. The axial stretching or compression of the circulation mechanism 300 provides vibration isolation and noise reduction, and the elastic mechanism 400 further reduces vibration. The circulation mechanism 300 also provides thermal insulation, preventing contact between the heat source piping and the fire-resistant bulkhead 10.

[0044] Specifically, a gap is provided between the outer wall of the mounting tube mechanism 100 and the inner wall of the through hole 11 to prevent the mounting tube mechanism 100 from colliding with the through hole 11 when the mounting tube mechanism 100 moves along the axial direction. In this embodiment, the gap between the two is 10 mm.

[0045] More specifically, the circulation mechanism 300 includes a flange 310, an expansion body 320, and a conduit 330. The conduit 330 is connected to both ends of the expansion body 320. The end of the conduit 330, distal from the expansion body 320, is provided with a flange 310. The flange 310 is capable of connecting to the heat source piping system. Both the conduit 330 and the expansion body 320 allow the medium in the heat source piping system to flow, and the flange 310 ensures a reliable connection between the conduit 330 and the heat source piping system.

[0046] The expansion body 320 has the characteristic of thermal expansion and contraction. When the medium temperature in the heat source piping system is high, the expansion body 320 expands due to the heat. However, under the constraints of the elastic mechanism 400 and the mounting pipe mechanism 100, the overall expansion energy of the expansion body 320 is converted into a volume change and axial stretching along the axis, thereby counteracting the compression of the elastic mechanism 400. Conversely, when the medium temperature in the heat source piping system decreases, the expansion body 320 begins to contract and recover, and the elastic mechanism 400 also recovers. This repetitive process, during which the expansion body 320 expands and contracts, absorbs and compensates for the thrust, vibration, and abnormal noise caused by the fire-proof penetration device on the fire-resistant bulkhead 10.

[0047] More specifically, the elastic mechanism 400 includes a slip ring structure 410, a sealing plate 420, and an elastic element 430. The slip ring structure 410 is disposed around the circumference of the circulation mechanism 300 and slidably abuts the inner wall of the mounting tube mechanism 100. The sealing plate 420 is fixedly disposed at the end of the mounting tube mechanism 100. The elastic element 430 is sandwiched between the slip ring structure 410 and the sealing plate 420. The elastic element 430 can be extended and retracted in the axial direction of the circulation mechanism 300. In this embodiment, the elastic element 430 can be a spring as known in the art.

[0048] Preferably, in this embodiment, the above-mentioned slip ring structure 410 is provided at the connection between the expansion body 320 and the conduit 330. The two slip ring structures 410 are respectively connected to the sealing plates 420 at both ends of the mounting tube mechanism 100 via corresponding elastic elements 430. During the process of thermal expansion and contraction of the expansion body 320, the slip ring structures 410 at both ends of the expansion body 320 can move along the axial direction of the mounting tube mechanism 100, thereby causing the elastic elements 430 at both ends of the expansion body 320 to undergo elastic deformation.

[0049] Preferably, the elastic mechanism 400 includes a plurality of elastic elements 430, which are distributed in a circular array and arranged around the expansion body 320. They are all connected to the slip ring structure 410 to ensure the coaxiality of the expansion body 320 in the direction of expansion, stretching or retraction with the axial direction of the mounting tube mechanism 100.

[0050] Continue to refer to Figure 1 The mounting pipe structure 100 includes an outer pipe structure 110 and an inner pipe structure 120. The inner pipe structure 120 is inserted into the outer pipe structure 110, with a gap between the inner pipe structure 120 and the outer pipe structure 110. This gap between the inner pipe structure 120 and the outer pipe structure 110 provides a certain degree of thermal insulation. In this embodiment, the gap between the inner pipe structure 120 and the outer pipe structure 110 is specifically 70 mm.

[0051] Specifically, the gap between the outer tube structure 110 and the inner tube structure 120 is filled with a fire-resistant insulation layer 130. The fire-resistant insulation layer 130 can effectively play the role of heat insulation, vibration reduction and noise reduction.

[0052] More specifically, the peripheral side of the circulation mechanism 300 is spaced from the inner wall of the inner tube structure 120 to form a relief space 140. When the medium temperature in the heat source pipe system is high, this heat energy can be confined in the relief space 140, further enhancing the thermal insulation and noise reduction effects.

[0053] Continue to refer to Figure 1The mounting mechanism 200 includes a support plate 210 and a fixing base 220. The support plate 210 is connected to the peripheral side of the mounting pipe mechanism 100, and the fixing base 220 is fixedly connected to the fire-resistant division bulkhead 10. The support plate 210 and the fixing base 220 are detachably connected. In this embodiment, the support plate 210 and the fixing base 220 are connected to each other by bolts 240. In other embodiments, the support plate 210 and the fixing base 220 can also be connected by plug-in connecting bolts, etc.

[0054] Specifically, the installation mechanism 200 further includes a fire-resistant heat-insulating pad 230 , which is sandwiched between the support plate 210 and the fixing seat 220 to further ensure heat insulation and block heat conduction between the fire-resistant partition wall 10 and the installation pipe mechanism 100 .

[0055] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
