Description

Technical Field

[0001] The present application relates to the field of thermal insulation structures, and in particular to an engine compartment ceramic nanofiber fireproof thermal insulation structure. Background Art

[0002] The fireproof and heat-insulating structure of the engine compartment is a very important safety design in the fields of aviation, automobiles, etc. Its main purpose is to limit the spread of fire and protect the surrounding components and occupants when the engine fails or catches fire.

[0003] When the current engine compartment fireproof and heat-insulating structure is actually used, drastic changes in temperature when the engine is working may cause the sound insulation board material to expand and contract, resulting in reduced fit, reduced sound insulation effect, increased heat conduction, and vibrations generated by the operation of the engine. These vibrations may cause the sound insulation board to loosen and affect its position stability in the insulation structure. At the same time, the vibrations generated when the engine is running may cause the sound insulation board to gradually shift from its original position, resulting in poor contact.

[0027] The embodiment of the present application discloses a ceramic nanofiber fireproof and heat-insulating structure for an engine compartment.

The bottom of the sliding column 27 is fixedly connected to the side of the pressure plate 28 close to the sliding column 27, so that the sliding column 27 can drive the pressure plate 28 to move vertically. The heat insulation mechanism 2 also includes a connecting sleeve 21 sleeved on the outer wall of the connecting frame 25, and the side of the connecting sleeve 21 close to the panel 1 is in contact with the side of the panel 1 close to the connecting sleeve 21. The inner wall of the connecting sleeve 21 is in contact with the outer wall of the connecting frame 25, so as to wrap the outer wall of the connecting frame 25. The connecting frame 25 is made of rubber material, which is convenient for entry The sound insulation board 22 is sealed to prevent heat from overflowing. The side of the connecting sleeve 21 close to the sound insulation board 22 is fitted with the top of the sound insulation board 22. The sound insulation board 22 is made of sound insulation foam material to isolate noise. The side of the sound insulation board 22 close to the connecting sleeve 21 is fixedly connected to the bottom of the connecting frame 25, so that the connection is tighter. The bottom of the sound insulation board 22 is fixedly connected with a fireproof board 23. The fireproof board 23 is made of ceramic nanofiber, so it has good heat insulation and fire prevention functions. The bottom of the fireproof board 23 is fixedly connected with an adhesive layer 24. The adhesive layer 24 is made of heat-conducting glue, so it has good heat conduction function. The bottom of the pressure plate 28 is fitted with the top of the sound insulation board 22. The side wall of the horizontal plate 26 is fixedly connected with a horizontal rod 29. A threaded hole 1 is opened on the top of the horizontal rod 29. The vertical thread of the rotating column 210 passes through the threaded hole 1, so that the rotating column 210 is threadedly connected to the horizontal rod 29.

[0031] The staff fits the bottom of the adhesive layer 24 with the outer wall of the engine compartment, and then fixes the fireproof board 23 to the top of the adhesive layer 24, and then covers the sound insulation board 22 on the top of the fireproof board 23, and then sets the connecting sleeve 21 on the outer wall of the connecting frame 25, and then rotates the knob 211, the knob 211 will drive the rotating column 210 to rotate, the rotating column 210 will move vertically downward, the knob 211 will drive the connecting piece 212 to move vertically downward synchronously, the connecting piece 212 will drive the sliding column 27 to move vertically downward, when the sliding column 27 moves vertically downward, it will drive the pressure plate 28 to move vertically downward, thereby pressing down the sound insulation board 22, so that the bottom of the adhesive layer 24 is always in a fit state with the outer wall of the engine compartment.

[0032] Reference Figure 5 , Figure 6The end of the rotating column 210 away from the sound insulation board 22 is fixedly connected to the bottom of the knob 211, so that the rotating column 210 can drive the rotating column 210 to rotate. A second round hole is opened on the top of the connecting member 212, and the rotating column 210 movably passes through the second round hole, so that the rotating column 210 and the connecting member 212 are rotatably connected. The diameter of the knob 211 is larger than the diameter of the round hole of the connecting member 212. Therefore, when the knob 211 moves vertically downward, it will drive the connecting member 212 to move downward synchronously. The end of the connecting member 212 close to the sliding column 27 is fixedly connected to the upper end of the sliding column 27, so that the connecting member 212 can drive the sliding column 27 to move vertically downward. The inner wall of the connection frame 25 is provided with a threaded hole 2, and the screw 213 is threadedly penetrated through the threaded hole 2, so that the screw 213 is threadedly connected to the connection frame 25. Since the connection sleeve 21 is made of rubber, as the thread of the screw 213 rotates, the screw 213 will penetrate the side wall of the connection sleeve 21 by rotating the thread, so that the connection sleeve 21 and the screw 213 are fixedly connected. The side wall of the nut 214 is provided with a threaded hole 3, and the screw 213 is threadedly penetrated through the connection sleeve 21 and extends to the outside. One end of the thread penetrates the threaded hole 3, so that the nut 214 is threadedly connected with the screw 213, and the screw 213 simultaneously penetrates the two connection sleeves 21 and the connection frame 25. Figure 6 , so as to splice multiple pieces. When the structure is dismantled and multiple pieces are re-spliced, the connecting sleeve 21 needs to be replaced to ensure that the screw 213 is tightly connected with the connecting sleeve 21 when it penetrates the connecting sleeve 21. A secondary penetration connection cannot be performed at the hole position on the side wall of the connecting sleeve 21 originally penetrated by the screw 213. The screw 213 needs to be used again to penetrate the hole in the complete side wall of the connecting sleeve 21, which can also ensure that a complete sealing ring is always formed on the outermost side of the thermal insulation structure.

[0033] When splicing, the staff aligns the threaded holes on the side walls of the two connecting frames 25, and then rotates the screw 213 to fix the screw 213 to the side wall of the connecting frame 25. The screw 213 then passes through the two connecting sleeves 21 in turn and docks with the threaded hole on the side wall of the second connecting frame 25. The nut 214 is then threadedly connected to the screw 213 from the other side, and the nut 214 is then rotated, so that the two connecting frames 25 are tightly connected together.

[0034] The implementation principle of the engine compartment ceramic nanofiber fireproof and heat-insulating structure of the present application embodiment is as follows:

[0035] The staff rotates the knob 211, which will drive the pressure plate 28 to move vertically downward, thereby pressing down the sound insulation board 22, so that the bottom of the adhesive layer 24 is always in contact with the outer wall of the engine compartment. When splicing, the staff aligns the threaded holes on the side walls of the two connecting frames 25, and then rotates the screw 213, so that the screw 213 passes through the two connecting sleeves 21 in turn and docks with the threaded hole on the side wall of the second connecting frame 25, and then threadably connects the nut 214 to the screw 213 from the other side, and then rotates the nut 214 to tightly connect the two connecting frames 25 together.
