The marine lifebuoy is a kind of escape device disclosed by the utility model, in particular is a kind of belt-type rapid inflatable lifebuoy that is worn on the waist, is usually belt-shaped, can be quickly inflated when using; this belt-type rapid inflatable marine lifebuoy comprises a life-saving air bag, this air-saving air bag is provided with an inflatable port; this inflatable port is provided with a one-way valve, an air storage cylinder, when the lifebuoy is used, after the automatic inflatable device encounters water, the needle will be the bottle of the gas storage cylinder Mouth puncture, thereby release the compressed gas in the gas storage cylinder, and then quickly complete the inflatable action to the air-saving air bag, in addition, the marine lifebuoy because the utility model discloses in adopts the structure that the air-saving air bag is folded and wearable, the utility model discloses has the following beneficial effects: it is convenient to wear; can quickly fill the air-saving air bag with gas; the safety performance is high.
The boat lifebuoy can be equipped with attachments, including a floating lifeline, a self-lighting floating lamp, or a self-emitting smoke signal. Lifebuoys are one of the main types of life-saving equipment, usually used as safety protection products in water disaster relief and related production and operation processes. At present, there are three main forms of domestic lifebuoy products: polystyrene cloth lifebuoy, polyurethane polyethylene composite marine lifebuoy and crust polyethylene lifebuoy. Due to the uneven quality of lifebuoy products, different prices and different application ranges, the lifebuoys that meet the configuration requirements should be carefully selected when purchasing. Qualified marine lifebuoy products shall have relevant material inspection reports, type test reports and bolt inspection certificates.
The marine lifebuoy should be able to support 14.5kg of iron to float in fresh water for 24 hours. In the case of free suspension, the lifebuoy should be able to bear the weight of 90kg for 30min without cracking and deformation. Marine lifebuoys equipped with a spontaneous smoke signal and a quick-throw device attached to a self-lit floating lamp should be able to trigger the device when released. It should be resistant to high and low temperatures, without shrinkage, rupture, expansion and decomposition. The periphery shall be equipped with a floating handle cable with a diameter of not less than 9.5mm and a length not less than four times the outer diameter of the marine lifebuoy. This cord should be fastened to four equidistant positions around the perimeter of the ring body, and form four grommets of equal length. After throwing from the specified height, there should be no cracking or breaking.
It is not a marine lifebuoy and must not be used as a lifesaving device. The national standards for the implementation of swimming rings and lifebuoys are different, and lifebuoys play a life-saving role, and it has many ancillary functions; Whereas, swimming rings are defined as water toys, and only the standard of playing with lifebuoys is implemented. Therefore, compared with the real marine lifebuoy, the toy swimming ring is easy to break and leak, the compression resistance is very poor, it is easy to burst, the plastic surface is slippery when exposed to water, it is difficult to grasp, and it can only play a certain auxiliary or protective role in water leisure sports, and it is dangerous if it is brought to deep water.
It should be resistant to high and low temperatures, without shrinkage, rupture, expansion and decomposition.
After the marine lifebuoy is thrown from the specified height, it should not crack or break.
It should be resistant to oil, without shrinkage, cracking, swelling and decomposition.
It should be fire-resistant and should not be burned or continue to melt after overheating.
It should be able to support 14.5kg of iron to float in fresh water for 24 hours.
In the case of free suspension, the marine lifebuoy should be able to bear the weight of 90kg for 30min without cracking and deformation.
Marine lifebuoys equipped with a spontaneous smoke signal and a quick-throw device attached to a self-lit floating lamp should be able to trigger the device when released.
When the lifebuoy is hung freely, it should be able to bear 90 kg of weight in 30 minutes, and during this time period, the lifebuoy will not break, let alone deform.
Marine lifebuoy refers to a type of lifesaving equipment on the water, usually made of cork, styrofoam, or other lightweight materials with a small specific gravity, and is covered with canvas, plastic, etc. Boat lifebuoys for swimming Xi can also be made of rubber and filled with air, also known as rubber rings. Any regular product should have basic elements such as factory name, factory address, certificate, production date, etc. At the same time, the production should be operated in accordance with the relevant quality standards, and the instructions for use in Chinese should be attached. The quality supervision department reminds the general public that the marine lifebuoy is a special life-saving equipment, so you must pay attention to it when purchasing, so as not to cause a big disaster when swimming. The weight of the lifebuoy should be greater than 2.5 kg. A marine lifebuoy equipped with a spontaneous smoke signal and a quick-throwing device attached to a self-lit floating lamp should weigh more than 4 kg.
