DETAILED DESCRIPTION

[0030] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0031] In the embodiments, two air guide subassemblies 3 are symmetrically arranged on the inner side of the installing main body 1. Figures 1-5 A kind of fireproof plugging device for ventilation engineering is given, which can be selected but is not limited to including: installing main body 1;

[0032] Plugging assembly 2 is arranged on the inner side of installing main body 1, which includes two limit blocks 24, which are symmetrically arranged on the inner side of installing main body 1;Plugging plate 25 can be placed between the upper surfaces of the two limit blocks 24;

[0033] Two air guide subassemblies 3 are symmetrically arranged on the inner side of installing main body 1.

[0034] Two ventilation pipelines 4 are respectively arranged on the inner side of the two air guide subassemblies 3.

[0035] This embodiment provides a fireproof sealing device for ventilation engineering. The sealing component 2 can seal the ventilation duct 4 in the event of a fire, thereby preventing the fire from spreading further. At the same time, the sealing component 3 can improve the sealing speed of the ventilation duct 4.

[0036] Furthermore, such as Figure 3 As shown, the mounting body 1 in the preferred embodiment of this utility model further includes a clearance hole 11, which is formed on the upper surface of the mounting body 1; a limiting groove 12, which is formed on the inner bottom of the mounting body 1; and two mounting holes 13, which are formed on the left and right sides of the mounting body 1 respectively.

[0037] Furthermore, such as Figure 4 As shown, the sealing component 2 in the preferred embodiment of this utility model further includes a sealing sleeve 21 disposed between the inner sides of the clearance hole 11 and the limiting groove 12, and a sealing plate 25 slidably disposed on the inner side of the sealing sleeve 21; two fixing holes 22 are respectively opened on the left and right sides of the sealing sleeve 21, and two air guiding components 3 are respectively symmetrically disposed on the inner sides of the two fixing holes 22; and two placement holes 23 are respectively opened on the front and rear surfaces of the sealing sleeve 21.

[0038] Furthermore, two limiting blocks 24 are respectively located inside the two placement holes 23, and the end of the limiting block 24 near the sealing plate 25 is located inside the sealing sleeve 21. The limiting block 24 is a paraffin limiting block.

[0039] More specifically, the outer side of the sealing plate 25 fits snugly against the inner side of the sealing sleeve 21, which ensures the sealing effect of the sealing plate 25 on the two fixing holes 22.

[0040] This embodiment provides several preferred embodiments of the sealing component 2. When a fire occurs, the high-temperature air from the fire enters the ventilation duct 4 via the sealing sleeve 21. The high-temperature air in the ventilation duct 4 then enters the sealing sleeve 21. Subsequently, the limiting block 24 melts under the influence of the high-temperature air. The softened limiting block 24 causes the sealing plate 25 to lose its limiting function, allowing it to completely slide into the sealing sleeve 21, thereby sealing the two fixing holes 22. This prevents the fire from spreading within the ventilation duct 4. This eliminates the need for electrical equipment, thus avoiding equipment failure during a fire and ensuring the reliability of sealing the ventilation duct 4.

[0041] Furthermore, such as Figure 5 As shown, the air guide assembly 3 in the preferred embodiment of this utility model includes an installation sleeve 31 located inside the fixing hole 22; an installation groove 32 located at the end of the installation sleeve 31 away from the sealing plate 25, and a ventilation duct 4 located inside the installation groove 32; and two air guide pipes 33 located on the outside of the installation sleeve 31 in a symmetrical and interconnected manner.

[0042] Further, the air outlet end of the air guide pipe 33 corresponds to the placement hole 23, and the end surface of the air guide pipe 33 close to the sealing sleeve 21 is located on the same horizontal plane as the side of the sealing plate 25 close to the mounting sleeve 31, so that when the sealing plate 25 completely falls into the sealing sleeve 21, the sealing plate 25 will also seal the air guide pipe 33.

[0043] In this embodiment, a plurality of preferred embodiments of the air guide assembly 3 are given, and the mounting groove 32 is arranged on the mounting sleeve 31, so that the ventilation pipe 4 can be limited and installed, thereby ensuring the stability of the ventilation pipe 4 in daily use. When a fire occurs, the high-temperature air in the ventilation pipe 4 will enter the two air guide pipes 33 from the mounting sleeve 31, and the air guide pipes 33 will guide the high-temperature air to the placement hole 23, so that the high-temperature air can melt the limiting block 24 from the outside. In this way, the limiting block 24 can be melted from the inside and the outside at the same time, thereby improving the efficiency of the sealing plate 25 in sealing the fixing hole 22.
