Description

Lifesaving device for crew overboard

technical field

The invention belongs to the field of ship auxiliary equipment, and in particular relates to a lifesaving device for crew members falling into the water.

Background technique

Ships generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, ships are also extended to buildings erected to make traffic more convenient for crossing mountain streams, unfavorable geology or meeting other transportation needs. When people fall into the ship by accident, or people who fall into the water during flood disasters are very dangerous, for the safety of the crew, the ship is often equipped with a life buoy. Lifebuoy refers to a kind of water lifesaving equipment, usually made of cork, foam plastic or other light materials with small specific gravity, and covered with canvas, plastic and so on. Life buoys for swimming practice can also be made of rubber and filled with air, also known as rubber rings. The exterior color of the lifebuoy should be orange-red without color difference. The surface of the lifebuoy should have no unevenness or cracks. Four equally spaced positions along the circumference of the lifebuoy should be surrounded by retroreflective tape with a width of 50 mm. The lifebuoy should be resistant to high and low temperatures, without shrinkage, rupture, expansion, or decomposition. After the lifebuoy is dropped from the specified height, there should be no cracking or breaking. The lifebuoy should be oil-resistant and free from shrinkage, rupture, expansion and decomposition. The lifebuoy should be fire-resistant and should not burn or continue to melt after being overfired. The lifebuoy should be able to support a 14.5kg iron block to float continuously in fresh water for 24 hours. Under the condition of free suspension, the life buoy should be able to bear the weight of 90kg for 30 minutes without breaking or permanent deformation. For a lifebuoy equipped with a self-igniting smoke signal and a quick-throwing device attached to a self-igniting buoy, the device should be triggered when released. When the lifebuoy is hung freely, it should be able to bear a weight of 90 kilograms in 30 minutes, and during this period of time, the lifebuoy will not break or deform.

However, the function of the life buoy is relatively single. It is only used by people and plays a life-saving role in the event of a person falling into the water. However, in the actual navigation process, the frequency of use of the life buoy is not particularly high. Going up and not using it will cause a waste of resources. After the existing ship personnel fall into the water, they need to go into the water for rescue, but before the rescue, they will throw the lifebuoy to the drowning person. However, manpower is limited after all due to various factors on the water surface. Under the influence, the lifebuoy may not be accurately and powerfully thrown to the drowning personnel, which may endanger the safety and health of the drowning personnel to a certain extent, so it is urgent to invent a kind of ship drowning rescue mechanical device. Currently published lifebuoys for ship rescue, such as Chinese invention patent, application number 202020750750.1, application date 2020.05.08 discloses a multi-purpose lifebuoy for ships. The lifebuoy is equipped with a first rubber plate, a second rubber plate and a rubber airbag to help people fall into the water. In addition to providing buoyancy for personnel, it can also provide stored water for those who fell into the water. However, the device has a large overall weight, is not easy to retract, and cannot be accurately delivered to the vicinity of people who fell into the water far away from the boat. It is of great significance to save the life of the crew in the water, and to have efficient and wear-free marine life-saving equipment.
