[0038] Please refer to Figures 1 to 4 hereinafter, the chimney opening reinforcement device provided by the present utility model will be described. The chimney opening reinforcement device includes a first support frame 10, a protective cover 20 and a reinforcing rib 30. The first support frame 10 includes two transverse beams 11 and two longitudinal beams 12. The transverse beams 11 and the longitudinal beams 12 are both used to be fixed on the cylinder 60 near the chimney opening 70. The two transverse beams 11 and the two longitudinal beams 12 enclose a rectangular structure sleeved on the outer periphery of the chimney opening 70; the protective cover 20 is sleeved on the outer periphery of the chimney opening 70 and is fixedly connected to the first support frame 10; the reinforcing rib 30 is connected to the outer wall of the chimney opening 70 and is spaced from the inner surface of the protective cover 20.

[0039] Optionally, both the cross beam and the longitudinal beam 12 are I-beams.

[0040] Compared with the prior art, for the chimney opening reinforcement device provided in this embodiment, the first support frame 10 is fixed on the chimney cylinder 60 (hereinafter simply referred to as the cylinder 60) near the chimney opening 70. Subsequently, the protective cover 20 is installed within the rectangular framework formed by the first support frame 10. Finally, the reinforcing rib 30 is installed on the outer wall of the chimney opening 70. By providing the protective cover 20, not only can the chimney opening 70 be protected from high temperature, wind pressure and other damages, but also the reinforcing rib 30 can be protected to avoid corrosion of the reinforcing rib 30 and the chimney opening 70, and the service life of the chimney opening 70 and the reinforcing rib 30 can be extended; the protective cover 20 and the reinforcing rib 30 play a role in strengthening the chimney opening 70, and the protective cover 20 is connected to the first support frame 10, and the structure of the surrounding cylinder 60 is utilized to realize the reinforcement of the chimney opening 70, avoiding deformation or damage of the chimney opening 70.

[0041] In some embodiments, an improved implementation manner of the above-mentioned chimney opening reinforcement device may adopt the structure as Figures 1 to 3 shown. Refer to Figures 1 to 3, the chimney opening reinforcement device further includes a second support frame 40. The two ends of the second support frame 40 are respectively connected to two longitudinal support beams 12. The second support frame 40 is used to sleeved on the cylinder 60 near the chimney opening 70. The second support frame 40 is sleeved on the outer periphery of the cylinder 60 and connected to the two longitudinal support beams 12, which improves the installation stability of the protective cover 20, and further improves the reinforcement strength of the chimney opening 70.

[0042] In some embodiments, a specific implementation manner of the above-mentioned second support frame 40 can adopt the structure as shown in Figure 1 and Figure 3 . Refer to Figure 1 and Figure 3 . The second support frame 40 includes a plurality of reinforcement rings 41, and the plurality of reinforcement rings 41 are spaced apart in the vertical direction. The plurality of reinforcement rings 41 are distributed in the space between the two transverse support beams 11. The plurality of reinforcement rings 41 are spaced apart, which not only improves the connection strength and stability between the first support frame 10 and the cylinder 60, but also saves materials and reduces costs.

[0043] In some embodiments, an improved implementation manner of the above-mentioned chimney opening reinforcement device can adopt the structure as shown in Figures 1 to 3 . Refer to Figures 1 to 3 . The chimney opening reinforcement device further includes a connecting flange 50, and the connecting flange 50 is arranged on the outer periphery of the chimney opening 70; wherein, the reinforcing ribs 30 are respectively fixedly connected to the connecting flange 50, the outer wall of the chimney opening 70, and the outer wall of the cylinder 60 near the chimney opening 70. The connecting flange 50 facilitates the connection between the chimney opening 70 and other pipes, and further processes the flue gas; by setting the connecting flange 50, the reinforcing ribs 30 can transfer the force to the cylinder 60 and the connecting flange 50 when the chimney opening 70 is under pressure, reducing the probability of damage and deformation of the chimney opening 70.

The reinforcing ribs 30 are provided with avoidance holes 31 corresponding to the intersection of the connecting flange 50 and the chimney opening 70, and the intersection of the chimney opening 70 and the cylinder 60. The angle between the connecting flange 50 and the outer wall of the chimney opening 70 is a right angle, the chimney opening 70 is a rectangular structure, the cylinder 60 is a cylindrical structure, and the angle between the chimney opening 70 and the cylinder 60 is an obtuse angle. If the reinforcing ribs 30 are to be fitted to the above two intersections, corresponding angles need to be machined on the reinforcing ribs 30. By setting the avoidance holes 31, the machining of the angles can be replaced, which facilitates the installation of the reinforcing ribs 30 and reduces the machining cost of the reinforcing ribs 30.

[0045] In some implementations, an improved implementation manner of the above-mentioned protective cover 20 can adopt the structure as shown in Figure 2and Figure 4 the structure shown. Refer to Figure 2 and Figure 4 , a shielding ring 21 is further provided on the front side of the protective cover 20.

[0046] In some embodiments, an improved implementation manner of the above-mentioned protective cover 20 can adopt the structure shown in Figure 2 and Figure 4 . Refer to Figure 2 and Figure 4 , a buffer layer 22 is further provided on the inner ring of the protective cover 20. There is a certain interval between the protective cover 20 and the strengthening rib 30. When the protective cover 20 is deformed or slides due to strong wind, the buffer layer 22 can prevent a strong collision between the strengthening rib 30 and the protective cover 20, and avoid damage to the protective cover 20.

[0047] Specifically, the protective cover 20 is made of a composite material resistant to high temperature and high pressure (such as polyimide composite material, high temperature and high pressure numerical value, ceramic and metal filled composite, high temperature and high pressure resin, etc.), and an anti-corrosion layer can also be provided on the outer surface of the protective cover 20. The protective cover 20 can protect the chimney opening 70 from external erosion and physical damage, and extend the service life of the chimney opening.

[0048] In some embodiments, a specific installation manner of the above-mentioned protective cover 20 can adopt the structure shown in Figure 2 and Figure 4 . Refer to Figure 2 and Figure 4 , the upper and lower sides of the protective cover 20 are fixedly connected to the outer wall of the cylinder body 60, and the left and right sides of the protective cover 20 are fixedly connected to the two longitudinal beams 12.

[0049] As a deformed implementation manner of the installation of the protective cover 20, the upper and lower sides of the protective cover 20 are fixedly connected to the two transverse beams 11, and the left and right sides of the protective cover 20 are fixedly connected to the two longitudinal beams 12.

[0050] The above installation manner of the protective cover 20 can realize the diversification of the assembly of the protective cover 20. Specifically, the installation of the protective cover 20 can be carried out according to the on-site construction conditions, which is convenient for operation.

[0051] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
