Embodiment 1
[0027] Such as Figure 1-7 As shown, the present invention provides a modular spherical crown-shaped overturning structure that withstands large external pressure, including a large storage body 1 and a spherical crown-shaped overturning structure 2, and a large storage body 1 and a spherical crown-shaped overturning structure 2. Through the rotary connection of the hinge connection structure 22A3, the work tasks in the two states of opening and closing can be realized; when the modular spherical crown flip structure that withstands large external pressure is in the open state, it can carry out internal and external operations, transportation and maintenance, etc. work; when the modular spherical crown-shaped overturning structure subjected to large external pressure is in the closed state, the protection of the internal facilities and equipment of the large storage body 1 is realized. The spherical crown-shaped overturning structure 2 is provided with a cylinder 22, and the sp...

The invention discloses a modular spherical crown flip structure with large external pressure. The spherical crown flip structure is provided with a cylinder body, one end of the cylinder body is provided with an outer skin, and the other end of the cylinder body is provided with a lower protection plate. The inside of the cylinder body is a filling cavity provided with a spherical crown. The cylinder body is composed of six parts of a first cylinder body block, a second cylinder body block, a third cylinder body block, a fourth cylinder body block, a fifth cylinder body block and a sixth cylinder body block. The first cylinder body block is provided with a hinge connecting structure. The spherical crown flip structure is novel in structure, is in slewing connection with a hinge of a largewarehousing machine body, and can achieve working tasks of two states of opening and closing. When the modular spherical crown flip structure with the large external pressure is in the opening state,inside and outside operation, transportation and maintenance can be conducted.
Description
technical field [0001] The invention relates to the technical field of aerospace external pressure-bearing structures, in particular to a modular spherical crown-shaped overturning structure that withstands large external pressures. Background technique [0002] At present, tasks such as satellite payload launch, long-distance material transportation, and emergency rescue have the characteristics of large transport load, urgent implementation time, and high process risks, and are generally realized through large-scale aerospace equipment. Usually, these large-scale aerospace equipment should be arranged in large-scale storage facilities that are convenient for equipment safety, mobile transportation and suitable environmental conditions according to the target tasks, mobile transportation conditions and equipment safety protection needs. For these large storage facilities, their own structural protection and safety capabilities such as anti-terrorist attacks and shock wave c...
