Problems solved by technology

The invention provides a crawler-type walking mechanism for amphibious boats, which has the advantage of good passability; the crawler can make the amphibious boat walk on wetlands, snowy fields or swamps, although the pressure between the hull and the ground is reduced, but the existing amphibious The bottom plate of the ship is "V" or inverted "V", which makes the hull itself have a high pressure when it touches the ground, which can easily cause the hull to sink. For the structure of the hull bottom plate, it is necessary to design an amphibious ship decompression bottom plate, used to reduce the pressure between the hull and the ground

Abstract

The invention discloses an amphibian vehicle pressure-reducing bottom plate. The amphibian vehicle pressure-reducing bottom plate comprises a steel pipe layer, a PVC layer is arranged at the upper end of the steel pipe layer, a zinc plating layer is arranged at the upper end of the PVC layer, an anti-pressure foam layer is arranged at the upper end of the zinc plating layer, a stainless steel layer is arranged at the upper end of the anti-pressure foam layer, and a paint layer is arranged at the upper end of the stainless steel layer; and the thickness of the stainless steel layer is 2-5 mm, and the stainless steel layer comprises the following ingredients of, by weight, 45-60% of Fe, 17.0-19.0% of Cr, 8.0-10.0% of Ni, 0.07-0.20% of C and 0.5-0.8% of Si. According to the amphibian vehicle pressure-reducing bottom plate, corrosion of the interior of the pressure-reducing bottom plate is avoided through the PVC layer, corrosion of a vehicle bottom basal plate is avoided through the zinc plating layer , the contact area of a vehicle body and the ground is increased through the steel pipe layer, intensity of pressure is reduced, the amphibian vehicle can conduct rescue on a wetland, a snow land or a marsh and cannot sink, the rescue speed is quickened, and property loss of people is reduced greatly.

Description

technical field [0001] The invention relates to the technical field of snow amphibious boats, in particular to a decompression bottom plate of an amphibious boat. Background technique [0002] Amphibious boats have gradually attracted people's attention because of their convenience and speed. They have important applications in urban flood relief, emergency drills, emergency rescue in unspecified waters, tidal flat breeding, and even military beach landings. [0003] For example, the Chinese patent application No. 201520022959.5 discloses a crawler-type traveling mechanism for amphibious ships, the mechanism includes at least one driving wheel driven by an oil cylinder, and at least one driven wheel, and the driving wheel and driven wheel are coated There are crawlers, and a lifting mechanism is fixed on the hull of the amphibious ship, and the lifting mechanism is connected with the driving wheel or the driven wheel. The lifting mechanism includes a lifting cylinder, and th...
