Combined type anti-explosion energy absorption device

Abstract

The invention discloses a combined type anti-explosion energy absorption device. The combined type anti-explosion energy absorption device comprises a surface thermal insulation energy absorption layer, a middle electromagnetic explosion resistance layer, a buffering energy consumption layer and a hydraulic supporting structure. The surface thermal insulation energy absorption layer comprises an upper surface plate, a lower surface plate and a sandwich layer. The sandwich layer is a porous ceramic material, the upper surface plate is a combined type wave plate, and a high-temperature-resistantfireproof coating is smeared on the outer surface of the upper surface plate. The electromagnetic explosion resistance layer is formed by an electromagnetic rubber bag array. The buffering energy consumption layer comprises an upper surface plate, a lower surface plate and a sandwich layer structure. The sandwich layer structure is a honeycomb type hollow prism, and the honeycomb type hollow prism is filled with quartz sand materials. The hydraulic supporting structure comprises spring hydraulic supporting rods, top suspension springs and outer plates. The combined type anti-explosion energyabsorption device adopts the multi-level grading consumption of the explosive blast load energy, has the advantages of being high in anti-explosion capacity, high in energy absorption efficiency, resistant to high temperature and low in plastic deformation, is small in occupied space, can be recycled and is high in practicability, simple in installation technology and convenient to install.

Description

technical field [0001] The invention belongs to the technical field of explosion-proof equipment and relates to a composite explosion-proof energy-absorbing device. Background technique [0002] With the development of economy, countries all over the world have an increasing demand for energy. As an important facility for the exploitation of offshore oil and gas resources, offshore platforms have served in complex and harsh marine environments for a long time. There are many mechanical equipment on the platform, and the internal pipelines and lines of the platform structure are densely arranged, which is prone to fire and explosion accidents. Offshore platforms are typical representatives of high-input, high-risk, and high-yield structures. The platforms store a large amount of oil or natural gas. Once a fire or explosion accident occurs, it will not only cause casualties and major economic losses, but also cause serious damage to the marine environment and marine ecology. ...

AI Technical Summary

Problems solved by technology

At present, the main forms include circular tube sandwich panels, steel sandwich concrete and steel plate-sand combination explosion-proof wall explosion-proof devices and other structural forms. Traditional explosion-proof devices have large plastic deformation, low explosion-resistant strength, complex form and process, and heavy structural weight.
