Description

Fixed remote launching and automatic recovery type lifesaving device

The technical field is as follows:

the invention relates to a fixed remote launching and automatic recovery type lifesaving device, and belongs to the technical field of water emergency rescue and rescue equipment.

Background art:

the life buoy is one of water life-saving equipment, and is usually made of cork, foamed plastic or other light materials with small specific gravity, and is covered by canvas, plastic and the like. The life ring for swimming practice can also be made of rubber, filled with air and also called as a rubber ring.

The common life buoy is generally in a PVC (polyvinyl chloride) plastic filled circular ring shape, is light in weight but not far thrown, and has poor rescue effect on people falling into water at a distance. Marine lifebuoys are annular life saving devices made of lightweight solid buoyancy materials, and are commonly made of closed cell foam. Rush, cork flakes and cork granules are prohibited from being used as buoyancy materials on sea-going vessels, nor are inflatable lifebuoys permitted. The lifebuoy for the river mainly adopts a polystyrene wrapping cloth lifebuoy, and the core material of the ring body of the lifebuoy adopts polystyrene material. The general production process is to wrap glass fiber cloth outside the core material of the ring body, and coat 3 layers of phenolic resin to form a sealed glass fiber reinforced plastic shell, and then coat the cloth and coat several layers of paint. On the ocean and fishery ships, China Ship inspection Bureau and China fishery Ship inspection Bureau have issued successive texts prohibiting the use of polystyrene-coated lifebuoys. The reason is that the material of the polystyrene cloth-covered lifebuoy has defects in performance, for example, the polystyrene material has poor oil resistance, and generates a shrinkage reaction after encountering oil, so that the buoyancy and the strength gradually disappear. The polyethylene composite life buoy adopts high-density polyethylene material as a shell, and polyurethane foam material is filled in the shell, so that the polyethylene composite life buoy is a novel life buoy at home. The polyethylene composite life buoy solves the problems that the polystyrene cloth-coated life buoy is not oil-resistant, the buoy body is easy to age under high-temperature environment and ultraviolet long-term radiation, a paint layer is peeled off, the manufacturing process is complex and the like, is an upgraded substitute product of the polystyrene life buoy, has the advantages of firm color, smooth surface, ageing resistance, high mechanical strength, corrosion resistance and the like, and has higher production cost than the polyethylene cloth-coated life buoy.

The throwing device is a device which takes compressed air or gunpowder as power and throws a rope and a life buoy to a target. The powder thrower can be divided into a pneumatic thrower and a gunpowder thrower according to power sources, wherein the gunpowder thrower makes loud sound when being launched and accompanies flame and sparks, so that the operation is unsafe. And both need to be manually pulled back onto the ship or pulled back to land. The common life buoy only provides floating and cannot bring a drowner back to the ship. When being used for the marine rescue of falling into water, to the very big region of wave, probably be washed far away by the wave in the twinkling of an eye, drowned person after struggling takes off the power and can't rely on self power to get back to the safety area or wait for the arrival of rescue for a long time moreover.

Current patent number is 201520862639.0's utility model patent, provides a remote transmission formula life buoy, and it adopts meets water automatic inflation device, meets water automatic inflation device and includes spring, water-soluble piece, steel needle, liquefied gas cylinder, the spring is blocked into compression state by water-soluble piece, and its top is equipped with the steel needle, treats that the life buoy falls into water after the water-soluble piece dissolve, makes the spring bounce, promotes the steel needle and punctures the liquefied gas cylinder, liquefied gas in the liquefied gas cylinder fills the life buoy, forms the life buoy. The life buoy has a few problems, firstly the structure of the device is inconvenient, the gas cylinder needs to be manually carried up to use, the life buoy is not suitable for civil use, only professional rescue workers can skillfully master the use mode after training, secondly the life buoy is an inflatable warhead, if the life buoy is scratched by sharp objects such as coke rocks and the like in the falling process, the life buoy can lose efficacy and has a great rescue hidden danger, and secondly the warhead can only be launched, and people falling into the water can return to a safety zone by means of self strength after grabbing.
