Example Embodiment
[0027] Example 1
[0028] See Figure 1~Figure 10 As shown, the earthquake refuge safety cabin includes an outer main body protective structure 1 and an inner protective cabin 2. Sixty steel springs pass between the outer shell of the inner protective cabin 2 and the inner wall of the outer main protective structure 1 3 Flexible and fixed connection, so that the inner protective cabin 2 is flexibly suspended inside the outer main protective structure 1.
[0029] The outer main body protection structure 1 is a frame structure as a whole, and the frame structure is connected and fixed by metal pipes 11 through bolts.
[0030] Each frame plane of the frame structure is provided with supporting reinforcement ribs fixedly connected by metal pipes 11 through bolts.
[0031] The cross section of the inner protective cabin 2 is elliptical. The inner protective cabin 2 is composed of two left and right halves 21, 22, and the left and right halves 21, 22 are butted and connected by bolts. The...
Example Embodiment
[0038] Example 2
[0039] The elastic component 3 is a pneumatic shock absorber.
[0040] The earthquake refuge safety cabin is different from Embodiment 1 in that the bulkhead material of the inner protective cabin 2 is a compression-resistant polyimide material.
[0041] The material of the flame-retardant insulation material layer 23 is asbestos material; the material of the flame-retardant protective material layer 24 is flame-retardant rubber foam material.
[0042] The outer surface of the overall frame structure of the outer main body protective structure 1 is covered with an outer protective sheet 13 fixed with a compressive polyimide.
Example Embodiment
[0043] Example 3
[0044] The elastic component 3 is a hydraulic shock absorber.
[0045] The earthquake refuge safety cabin is different from the embodiment 1 in that the bulkhead material of the inner protective cabin 2 is 25CrMo4 steel plate.
[0046] The material of the flame-retardant insulation material layer 23 is asbestos material; the material of the flame-retardant protective material layer 24 is flame-retardant plastic foam material.
[0047] The outer surface of the overall frame structure of the outer main body protective structure 1 is covered with an outer protective sheet 13 fixed with a 25CrMo4 steel plate.
