Abstract

The application provides a double-V lightning protection structure and a manufacturing method thereof, and relates to the field of lightning protection structures.The lightning protection structure comprises two groups of connecting bases symmetrically arranged at the bottom of a fixed base; and a blast-facing main explosion-proof plate is arranged at the bottom of the fixed base.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lightning protection structure, in particular to a double-V type lightning protection structure and a manufacturing method thereof. BACKGROUND

[0002] The mine-proof vehicle is a special vehicle that protects the personnel and structure inside the vehicle through a specific vehicle body protection structure to avoid damage caused by mine explosion. When the mine-proof vehicle is subjected to the effect of explosion shock wave, the bottom will be subjected to a constant upward instantaneous strong load, and then a large deformation will be caused to damage the internal structure of the vehicle and the passengers.

[0003] Due to the limited protection capability of the single-layer and flat-bottom structure, and the fact that the method of increasing the thickness to improve the protection capability will continuously increase the weight of the mine-proof vehicle, the single-layer flat plate scheme has been gradually eliminated. The single-layer deep V type structure has a large size in the height direction, which increases the center of gravity of the whole vehicle and affects the safety of high-speed driving and the passability of complex road conditions. The hollow double-V type or double-V type with interlayer structure is relatively complex, and the function of the inner plate cannot be fully exerted due to the existence of the hollow structure or the filling buffer layer. In addition, when the commonly used mine-proof structure is installed, it is impossible to determine whether the whole mine-proof structure is firmly fixed, and whether the mine-proof structure is installed to the specified position.

The defense function of each functional layer of the mine-proof structure composed of the blast-facing main explosion-proof layer, the pressure relief gap and the back side functional layer is refined. Even after being subjected to a higher TNT equivalent explosion impact, the back side functional layer can still maintain good integrity.
