Problems solved by technology

[0003] The "Poseidon" unmanned submersible developed by the Woods Hole Oceanographic Institution (WHOI) in the United States is equipped with alumina ceramic hollow balls and tanks that can be used in the deep sea of ​​11,000m, but unfortunately "Poseidon" had a submarine implosion accident, so it is urgent to find a structure that can effectively absorb the huge energy released after the implosion of the ceramic hollow ball in the deep sea, and avoid chain implosion reactions.

Embodiment 1

[0043] combine figure 1 and figure 2 As shown, the energy-absorbing protection structure of the ceramic hollow buoyancy ball according to the embodiment of the present invention includes a spherical shell, which is arranged on the surface of the ceramic hollow buoyancy ball 1. The spherical shell in this embodiment includes a first hemispherical shell 2 and a second hemispherical shell 2. There are two hemispherical shells, the first hemispherical shell 2 has the same structure as the second hemispherical shell, and there are water through holes 3 on it.

[0044] The thickness of the first hemispherical shell 2 and the second hemispherical shell are both 10 mm, and the thickness can be designed as long as it does not affect the buoyancy of the ceramic hollow buoyancy ball. The first hemispherical shell 2 and the second hemispherical shell are combined through a threaded structure, and in other embodiments, a riveting or locking component can also be used for combination.

Embodiment 2

[0051] like Figure 4 As shown, the energy-absorbing protection structure of the ceramic hollow buoyancy ball according to the embodiment of the present invention includes an ultra-high molecular weight polyethylene fiber 2 and a resin layer, and the ultra-high molecular weight polyethylene fiber 2 is evenly coated on any equator on the surface of the ceramic hollow buoyancy ball 1. , forming an ultra-high molecular weight polyethylene fiber layer, and coating an epoxy resin layer on the ultra-high molecular weight polyethylene fiber layer to cure the ultra-high molecular weight polyethylene fiber layer. The thickness of UHMWPE fiber layer is 20mm, and the material density of UHMWPE fiber 2 is 1g / cm 3 .

[0052] When the ceramic hollow buoyancy ball implodes in the deep sea, because the ball is wrapped with an energy-absorbing and explosion-proof ultra-high molecular weight polyethylene fiber layer, when the shell is damaged, no flying ceramic fragments will be generated, and...

Embodiment 3

[0057] The energy absorption protection structure of the ceramic hollow buoyancy ball according to the embodiment of the present invention includes a first hemispherical shell, a second hemispherical shell, an ultra-high molecular weight polyethylene fiber layer and a resin cured layer.

[0058] The thickness of the first hemispherical shell and the second hemispherical shell are both 3 mm, and there are water through holes thereon. The first hemispherical shell 2 and the second hemispherical shell 3 are combined by locking components to form a spherical shell. The first hemispherical shell 2 and the second hemispherical shell 3 are made of ultra-high molecular weight polyethylene fiber material with a material density of 0.95g / cm 3 .

[0059] Any equator on the surface of the spherical shell formed by the combination is uniformly coated with multiple layers of ultra-high molecular weight polyethylene fibers to form a plurality of ultra-high molecular weight polyethylene fiber...

Abstract

The technical scheme of the present invention discloses an energy-absorbing protection structure for a ceramic hollow buoyancy ball, comprising a spherical shell made of ultra-high molecular weight polyethylene fiber material, and the spherical shell is arranged on the surface of the ceramic hollow buoyancy ball. The technical scheme of the present invention adopts ultra-high molecular weight polyethylene as the material of the energy-absorbing protection structure of the ceramic hollow buoyancy ball, which can not only prevent the ceramic hollow buoyancy ball from being damaged by impact in all links of handling and installation, but more importantly, the ultra-high molecular weight polyethylene Ethylene has enough strength to effectively absorb the huge energy released by the ceramic hollow buoyancy ball when it implodes in the deep sea, so as to avoid affecting other structures of the submersible, especially to ensure the safety of the occupants in the manned submersible, and the overall The structure is simple and easy to manufacture.

Description

technical field [0001] The invention relates to the technical field of material protection, in particular to an energy-absorbing protection structure of a ceramic hollow buoyancy ball and a preparation method thereof. Background technique [0002] Deep diving technology is an important part of national defense security and marine resources development technology. Marine resources, especially the development and utilization of deep-sea resources, play an important role in the development strategies of various countries. Deep-sea exploration technology is the key to the development and utilization of deep-sea resources, and deep-sea buoyancy materials are an important guarantee for deep-sea exploration. [0003] The "Poseidon" unmanned submersible developed by the Woods Hole Oceanographic Institution (WHOI) in the United States is equipped with alumina ceramic hollow spheres and tanks that can be used in the deep sea of ​​11,000m, but unfortunately The submarine implosion acc...
