AI Technical Summary

Technical Problem

The existing cold storage structure is used on ocean-going fishing vessels, and it is difficult to adapt to the high pressure exerted by seawater on the hull plate of deep-sea vessels when operating in deep sea waters. As a result, the pressure is transmitted to the decorative panels through the connecting structure, which may damage the decorative panels.

Method used

A flexible insulation layer and connection components are used, including rigid connectors and elastic connectors. The rigid connectors are connected to the metal wall panels, and the elastic connectors are connected to the decorative panels. When under pressure, the elastic connectors deform to absorb part of the pressure, and the flexible insulation layer cooperates to absorb the remaining pressure to avoid direct action on the decorative panels.

Benefits of technology

It effectively protects the decorative panels and avoids damage caused by direct transmission of seawater pressure. It meets the corrosion resistance, lightweight density and low toxicity requirements of deep-sea ship cold storage, while also having good acoustic performance and vibration and noise reduction effects.

Abstract

The invention relates to a heat insulation structure for a deep-sea ship refrigeration house and an installation method, and relates to the technical field of deep-sea ship engineering.The heat insulation structure comprises a flexible heat insulation layer used for being fixed to the outer side of a metal wall plate; the decorative plate is arranged on the outer side of the flexible heat insulation layer; the connecting assembly is arranged in the flexible heat insulation layer and comprises a rigid connecting piece and an elastic connecting piece, one end of the rigid connecting piece is used for being connected with the outer side of the metal wall plate, the other end of the rigid connecting piece is connected with the elastic connecting piece, the rigid connecting piece and the decorative plate are arranged in a spaced mode, and the elastic connecting piece is connected with the decorative plate. When pressure acting on the metal wall plate is transmitted to the elastic connecting piece, the elastic connecting piece deforms and is matched with the flexible heat insulation layer to absorb part of pressure. Due to the fact that part of pressure acting on the metal wall plate can be absorbed by deformation cooperation of the elastic connecting piece and the flexible heat insulation layer, the pressure cannot directly act on the decorative plate, a certain protection effect is achieved, and the problem that the pressure possibly directly acts on the decorative plate from the metal wall plate is solved.
