Embodiment 1

[0015] Embodiment 1: A cylindrical instrument with a shorter length is described as an example.

[0016] like figure 1 As shown, the anti-rolling non-circular outer reinforcing ring device for the ultra-thin-walled pressure-bearing cylinder of a small deep-sea instrument includes a pressure-bearing cylinder 1 , a first outer reinforcement ring 2 and a second outer reinforcement ring 3 . The first outer reinforcement ring 2 and the second outer reinforcement ring 3 are located at both ends of the pressure-bearing cylinder 1 respectively, and are connected with the pressure-bearing cylinder 1 by welding; the first outer reinforcement ring 2 and the second outer reinforcement ring 3 The outer surfaces are respectively in the same plane as the two end surfaces of the pressure-bearing cylinder 1 , and the centerline of the pressure-bearing cylinder 1 is perpendicular to the first outer reinforcement ring 2 and the second outer reinforcement ring 3 .

Embodiment 2

[0017] Embodiment 2: A cylindrical instrument with a long length is used as an example for illustration.

[0018] like figure 2 As shown, when the length of the pressure-bearing cylinder 1 is long, a plurality of third outer reinforcing rings 4 can be provided according to the rigidity of the cylinder to enhance the rigidity of the pressure-bearing cylinder 1 .

Abstract

The invention relates to an anti-rolling non-circular outer reinforcing ring device for an ultra-thin-walled pressure bearing cylinder of a small deep-sea instrument. The anti-rolling non-circular outer reinforcing ring device comprises the pressure bearing cylinder, a first outer reinforcing ring and a second outer reinforcing ring; the first outer reinforcing ring and the second outer reinforcing ring are located at the two ends of the pressure bearing cylinder respectively and connected with the pressure bearing cylinder in a welding mode, and therefore the outer reinforcing rings are provided with connecting holes used for being reliably connected with a left end cover and a right end cover on the premise that the wall thickness of the pressure bearing cylinder is not increased; meanwhile, the outer reinforcing rings are further provided with lifting holes and fixing holes, and therefore underwater robot gripping and instrument positioning are convenient; the outer reinforcing rings are in a non-circular shape, and therefore the condition that the instrument rolls under the sea can be prevented. According to the anti-rolling non-circular outer reinforcing ring device, light weight of the deep-sea instrument can be achieved, and reliable connection between the cylinder and the end covers is guaranteed on the condition that the wall thickness of the cylinder is not increased.

Description

technical field [0001] The invention belongs to the field of small-scale deep-sea monitoring instruments and equipment, and in particular relates to an anti-rolling non-circular outer reinforcing ring device for an ultra-thin wall-thick pressure-bearing cylinder of a small-scale deep-sea instrument. Background technique [0002] The shell of the small deep-sea instrument includes a cylinder body and end caps at both ends, forming a seawater-proof airtight space, which belongs to an external pressure vessel and withstands the pressure of deep sea still water. The ultra-thin wall thickness value of the cylinder mainly depends on the minimum calculated wall thickness value of the pressure bearing formula of the external pressure vessel, and this minimum calculated wall thickness value does not include the threaded hole (used to connect the end cover) opened in the cylinder. Opening threaded holes in the barrel will result in increased wall thickness and increased weight. How t...
