Deep sea floating hose

Abstract

The invention discloses a deep sea floating hose. The deep sea floating hose comprises a bearing part, a buoyancy part and a two-end connecting component, and is characterized in that the bearing part is provided with an inner tube body framework bearing layer; a wear-resistant layer is arranged on the inner side of the inner tube body framework bearing layer; the outer side of the inner tube bearing layer is adhered to the buoyancy part through an inner tube external glue layer; pressure-resistant glass bead floating bodies and high-elasticity rubber layers are uniformly distributed on the buoyancy part at an interval along the axial direction; adhesive layers are arranged between the pressure-resistant glass bead floating bodies and the high-elasticity rubber layers; an outer reinforcing layer is adhered to the external part of the buoyancy part; an outer glue layer is adhered to the external part of the outer reinforcing layer. According to the deep sea floating hose, the damage resistance capacity during conveying of deep sea ore is improved; the deep sea floating hose can resist extremely large seawater pressure without deforming and is suitable for being used at the water depth of several thousand meters in deep sea; the requirements on change of the deep sea hose with movement of a construction system can be met, the deep sea floating hose has the capacity of adapting repeated turning movement, and the adaption life of the hose is prolonged.

Description

technical field [0001] The invention belongs to a rubber hose product, in particular to a deep-sea floating rubber hose. Background technique [0002] At present, the development and utilization of deep-sea resources is still in the initial stage, and there are still some issues that need to be solved urgently: 1. The extraordinary environment of the deep sea, the deep-sea environment is more severe and harsh, and the requirements for deep-sea operations and equipment are extremely high; 2. The special characteristics of deep-sea minerals The distribution state, the existing land and mining metallurgical processing technology cannot be applied; 3. Yang mine technology is very difficult, and the collected minerals must be transported from the seabed of several kilometers to the ocean surface. 4. The environmental limit standard of deep sea mining, the degree of disturbance to the seabed in deep sea mining operations is an extremely important limit index. [0003] Currently, ...

AI Technical Summary

Problems solved by technology

The mining vehicle of the mining system is directly dragged by the hose. During the working process, the shape of the hose changes with the movement of the system, and it needs to make frequent turning movements, which is not conducive to the smooth transportation of the fluid in the pipe. The currently provided hose is easily broken and damaged. Short service life and high operating costs
