U-shaped laser welding sandwich panel explosion prevention wall

Abstract

The invention provides a U-shaped laser welding sandwich panel explosion prevention wall and belongs to the technical field of explosion prevention. The U-shaped laser welding sandwich panel explosion prevention wall comprises a laser welding sandwich panel, a top edge supporting structure and side edge supporting structures, wherein the laser welding sandwich panel enables a core sandwich layer structure to be arranged between an upper panel and a lower panel, and the top edge and the two side edges of the laser welding sandwich panel are welded to the top edge supporting structure and the side edge supporting structures on a target upper portion module truss correspondingly; according to the U-shaped laser welding sandwich panel explosion prevention wall, the core sandwich layer structure is arranged to be in a U-shaped folding structure and welded to the upper panel and the lower panel in a laser mode, in-plane bending rigidity is larger, the specific strength is higher, energy absorption efficiency of the core sandwich layer structure is higher, thus plastic deformation, under explosion shock loading, of the explosion prevention wall is small, the explosion resistance design loading capacity is higher, the occupied area is smaller, the self-weight is smaller, and the explosion prevention wall is more suitable for an offshore platform; and the top edge supporting structure and the side edge supporting structures are arranged for mounting, adaptation is higher, and the mounting technique is simpler.

Description

technical field [0001] The invention relates to the technical field of explosion protection, in particular to an explosion-proof wall with U-shaped laser-welded sandwich panels. Background technique [0002] As the main equipment for the development of modern marine resources, offshore oil and gas production platforms require the platform to integrate oil and gas exploration, processing, processing, storage and other functions, resulting in more equipment installed on the platform and densely arranged. However, the harsh environment of the ocean can easily lead to the aging of these equipment, man-made accidents or equipment failures, causing oil and gas leakage, causing fire or explosion safety hazards, causing huge losses such as casualties, environmental pollution, etc., while the explosion-proof wall can prevent potential leakage, Equipment with high explosion risk is separated from key protection areas (living buildings, personnel work areas, key equipment areas, etc.),...

[0002] As the main equipment for the development of modern marine resources, the offshore oil and gas production platform requires the platform to integrate oil and gas exploration, processing, processing, storage and other functions, resulting in more equipment installed on the platform and densely arranged

However, the harsh environment of the ocean can easily lead to the aging of these equipment, man-made accidents or equipment failures, causing oil and gas leakage, causing fire or explosion safety hazards, causing huge losses such as casualties, environmental pollution, etc., while the explosion-proof wall can prevent potential leakage, Equipment with high explosion risk is separated from key protection areas (living buildings, personnel work areas, key equipment areas, etc.), and the explosion-proof wall bears the shock wave load of potential oil and gas explosions, so that the protection area is not subject to explosion impact and secondary chain damage is avoided , to a certain extent reduce the harm caused by the explosion, reduce casualties and property losses, therefore, the research on the explosion-proof wall has become the focus of attention

[0003] Traditional explosion-proof walls are generally corrugated or reinforced plate explosion-proof walls, but when these explosion-proof walls absorb the explosion impact energy through plastic deformation, the explosion-proof ability is poor due to the large plastic deformation, and the connection between these explosion-proof walls and the surrounding structures It is more complicated, and there is also the problem of low energy absorption efficiency
