Description

Self-inflating waterproof anti-collision device Technical Field The invention relates to the field of safety protection, in particular to a self-inflating waterproof anti-collision device. Background When sudden storms cause urban waterlogging, flood and mud-rock flow, when natural disasters such as earthquakes and tsunamis occur, when sudden accidents need water surface rescue, how to avoid the loss of large valuable property (such as automobiles) caused by water bubbles, important equipment and the like become a great trouble of the owner. The waterproof and anti-collision devices appear as if they were wearing a "life jacket" on water, and a solid waterproof barrier is created for them by science and technology and by chance. Traditional protection mode flexibility is poor, and is difficult to solve simultaneously and prevents sinking (aerify floating) and gas leakage problem. Most of the existing products still adopt an air pump for inflation, disasters need to be prejudged in advance, the operation is complicated, the air pressure is difficult to maintain for a long time, the automatic inflation device depends on a built-in battery, the air pump, the air pressure sensor and the liquid level sensor are configured, the problems of continuous voyage and energy consumption generally exist, the air pressure needs to be maintained by continuously supplementing air, and the duration of the battery is limited, generally about 40 hours. In addition, most of the current products are single trigger mechanisms (such as micro-pressure sensing), the sensitivity and accuracy are poor, and the products are frequently started by mistake. The existing products are single-air-chamber capsules, the protection performance of the existing products still has a room for improvement, part of the products can resist conventional impact, but the existing products can still be damaged when facing sharp edge tools and the like, and once the existing products are punctured and air-leaked, water can not enter the capsules to be discharged, so that more serious loss can be caused.
