Description

Technical Field

[0001] This utility model belongs to the field of forest fire prevention technology, specifically relating to a prefabricated firebreak. Background Technology

[0002] In areas where large forest areas such as nature reserves and state-owned forest farms meet surrounding farmland, villages, and roads, prefabricated firebreaks are set up as the first line of defense. For example, they are laid along one side of the road at the edge of the forest area. This effectively blocks external fire sources from entering the forest area, prevents small flames from being carried by the wind into the forest and causing large-scale fires, and protects the ecological security of the forest area. In areas where multiple forest areas are connected, setting up firebreaks between different forest areas can prevent the fire from spreading rapidly to adjacent forest areas after it starts in one forest area, curb the development of fires, and reduce the affected area.

[0003] Currently used firebreaks are typically prefabricated for ease of use and to respond to emergencies. However, the existing prefabricated firebreaks are connected by pre-drilling bolt holes at the joint edges, using bolts and nuts to fix adjacent sections together. During installation, it is important to tighten the bolts to ensure a tight connection, and the fixing process is relatively slow. Furthermore, flames can still easily leak out, requiring the use of fire-retardant sealant to seal around the bolt holes to prevent flame leakage. This cumbersome process results in low efficiency when isolating firebreaks during sudden forest fires. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model designs a prefabricated fireproof isolation strip, which facilitates rapid assembly during fireproof isolation, is convenient and quick, and improves sealing performance to prevent flame leakage.

[0005] This utility model discloses a prefabricated fireproof isolation strip, including a butt plate with openings on both the left and right sides. Each opening is fitted and snapped into an isolation plate. Pin holes are correspondingly provided on the left side of the top and bottom surfaces of the isolation plates, and clamping plates are correspondingly provided on the right side. The left end of the clamping plate is hinged to a mounting base on the right side of the isolation plate, and a pin is provided on the right end of the clamping plate. The pin of the left isolation plate connects to the pin hole of the right isolation plate to connect and fix the two isolation plates to the butt plate. Support frames are also correspondingly installed on the inner and outer end faces of the isolation plates. A fireproof inner liner is installed inside the isolation plate. The fireproof inner liner includes an outer shell, and inside the outer shell, from the inside out, are sequentially arranged an anti-crack layer, a reinforcing layer, a heat insulation layer, a filling layer, and a leak-proof layer.

[0006] The docking plate is also provided with a support plate. Several connecting posts are provided at equal intervals from top to bottom on both sides of the support plate. The connecting posts on both sides are respectively connected to the connecting holes opened on the side of the outer shell of the corresponding fireproof inner liner. Springs are wrapped around the connecting posts to support them between the support plate and the side wall of the outer shell.

[0007] The length of the connecting post is equal to the depth of the connecting hole.

[0008] The support frame includes hinged seats fixed to the inner and outer end faces of the isolation plate, a rotating rod rotatably connected to the hinged seat, a support leg connected downward to the rotating rod, and a support hinged to the end of the support leg.

[0009] The beneficial effects of this utility model are:

[0010] Compared with existing technologies, the prefabricated fireproof isolation strip of this utility model is assembled by splicing several butt plates and isolation plates. After splicing the butt plates and isolation plates, the pins on the clamping plates of the previous isolation plate are connected to the pin holes of the next isolation plate to fix the isolation plates in sequence, achieving rapid assembly. At the same time, a fireproof inner liner is installed inside the isolation plate. The fireproof inner liner is arranged from the inside out as a crack-resistant layer, a reinforcing layer, a heat insulation layer, a filling layer, and a leak-proof layer. When performing fireproof isolation, it improves the sealing performance and durability of the isolation plate, prevents flame leakage, and effectively blocks flames. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1

[0021] To address the problems of existing prefabricated firebreaks being inconvenient to assemble, having low installation efficiency, poor fire-resistant properties, and being prone to leakage, refer to... Figures 1 to 5 As shown, in this embodiment, a prefabricated fireproof isolation strip is provided, including a butt plate 1 with openings on both the left and right sides. Each opening is fitted and snapped into an isolation plate 2. Pin holes 3 are correspondingly provided on the left side of the top and bottom surfaces of the isolation plate 2, and clamping plates 4 are correspondingly provided on the right side. The left end of the clamping plate 4 is hinged to a mounting base 401 on the right side of the isolation plate 2. A pin 402 is provided on the right end of the clamping plate 4. The pin 402 of the left isolation plate 2 connects to the pin hole 3 of the right isolation plate 2 to connect and fix the two isolation plates 2 to the butt plate 1, forming a sealed fireproof isolation strip. Support frames are also correspondingly installed on the inner and outer end faces of the isolation plate 2 to support the entire fireproof isolation strip within the protected isolation area. A fireproof inner liner 9 is also installed inside the isolation plate 2. The fireproof inner liner 9 includes an outer shell 901, and inside the outer shell 901, from the inside out, are sequentially arranged an anti-crack layer 902, a reinforcing layer 903, a heat insulation layer 904, a filling layer 905, and a leak-proof layer 906.

[0022] When carrying out forest fire prevention isolation, several connecting plates 1 and isolation plates 2 are spliced ​​together as needed. After splicing the connecting plates 1 and isolation plates 2, the pins 402 on the clamping plate 4 of the previous isolation plate 2 are connected to the pin holes 3 of the next isolation plate 2 to fix the isolation plates 2 in sequence, so as to achieve quick assembly. At the same time, a fireproof inner liner 9 is installed inside the isolation plate 2. During fire prevention isolation, the sealing performance and durability of the isolation plate 2 are improved, flame leakage is prevented, and flames are effectively blocked.

[0023] To improve the tension and overall stability of the connection between the isolation plate 2 and the docking plate 1, and to enhance the sealing performance, a support plate 101 is installed inside the docking plate 1. Several connecting posts 102 are equidistantly arranged on both sides of the support plate 101 from top to bottom. Each connecting post 102 engages with a connecting hole 9011 on the side of the outer shell 901 of the corresponding fireproof inner liner 9. The length of the connecting post 102 is equal to the depth of the connecting hole 9011. A spring 103 is wrapped around the connecting post 102, providing support between the support plate 101 and the side wall of the outer shell 901. Through the docking connection of the connecting posts 102 and the connecting holes 9011, the isolation plate 2 and the docking plate 1 are stably engaged. Furthermore, under the support and tension of the spring 103, the connection between the isolation plate 2 and the docking plate 1 is more stable and tighter.

[0024] In this embodiment, the support frame includes hinged seats 5 fixed to the inner and outer end faces of the isolation plate 2. A rotating rod 6 is rotatably connected to the hinged seat 5. The rotating rod 6 is interference-fitted with the hinged seat 5, providing significant rotational damping and effectively supporting the structure. Support legs 7 are connected downwards to both sides of the rotating rod 6, and supports 8 are hinged to the ends of the support legs 7. The hinged supports 8 can adapt well to different ground conditions. The overall design allows the assembled protective isolation belt to be used in forest fire prevention and isolation scenarios, effectively providing fire protection.

These preferred embodiments do not describe all details exhaustively, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
