Description

Technical Field

[0001] This utility model relates to the field of lifesaving equipment technology, and in particular to a lifesaving device for ships. Background Technology

[0002] During ship navigation, lifesaving devices are key equipment to ensure the safety of crew and passengers. Their performance is directly related to the success rate of personnel escape in emergency situations. Currently, the most common ship lifesaving devices on the market include lifeboats, life rafts, and life rings. However, life rings still have many shortcomings in practical applications.

[0003] For example, Chinese patent CN202420967932.2 discloses a portable life ring for ships, which includes a ring body, an air chamber inside the ring body, an assembly tube fixedly installed on the front of the ring body, a slot inside the assembly tube, an air pump inside the slot, and a one-way air valve fixedly installed on the back of the slot.

[0004] Current lifebuoys lack buoyancy stability. After prolonged immersion or minor impact, some lifebuoys are prone to aging and damage of buoyancy materials, resulting in decreased buoyancy and inability to reliably support people who have fallen into the water. In addition, lifebuoys lack auxiliary rescue structures, and people who have fallen into the water may not be able to hold onto the lifebuoy stably in a panic. To address these issues, a life-saving device for ships is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art and to propose a life-saving device for ships.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a ship rescue device, comprising a lifebuoy body, the lifebuoy body comprising a ring body, a positioning and rescue component fixedly installed on the top of the ring body, multiple through holes symmetrically opened on the outer side of the ring body, and two gripping straps symmetrically distributed on the top of the ring body, both ends of the gripping straps being fixedly connected to elastic bands, and one end of the elastic bands being fixedly installed to the top of the ring body, a pressure sensor being fixedly installed inside the ring body, and multiple buoyancy bladders filled with carbon dioxide gas being evenly distributed inside the ring body, one end of each buoyancy bladder being fixedly connected to a sealing valve, the pressure sensor being electrically connected to the sealing valve, and the positioning and rescue component comprising a waterproof shell, a GPS positioning module, a wireless signal transmitter, and an audible and visual alarm, with a battery installed inside the waterproof shell.

[0007] Preferably, the GPS positioning module and the wireless signal transmitter are fixedly installed inside a waterproof housing, and multiple LED warning lights are fixed on the outside of the waterproof housing.

[0008] Preferably, the waterproof housing is provided with a switch on the top, and the waterproof housing is fixedly installed on the top of the ring body.

[0009] Preferably, two fixing plates are symmetrically distributed on the outer side of the ring body, and fixing holes are provided at both ends of the fixing plates.

In this utility model, multiple gripping straps and through holes are provided on the ring body. These gripping straps and through holes facilitate stable gripping by people who have fallen into the water, improving rescue safety. When the pressure sensor detects a drop in the internal pressure of the ring body, it automatically controls the sealing valve to open, releasing carbon dioxide gas from the independent buoyancy bladder. This causes the buoyancy bladder to expand, supplementing the buoyancy of the life ring and ensuring that the buoyancy always meets the rescue needs, ensuring that the life ring always maintains sufficient buoyancy to support people who have fallen into the water.

[0013] 2. In this utility model, by adding a positioning and rescue component, the GPS positioning module can obtain the location information of the lifebuoy in real time, and the wireless signal transmitter can transmit the location information to the receiving terminal on the ship's bridge in real time, which is convenient for rescuers to accurately locate the lifebuoy. The LED warning light provides a clear visual mark at night or in low visibility environments, and the audible and visual alarm emits a warning signal, providing rescuers with accurate positioning and clear markings, further improving the lifebuoy's recognizability. This lifebuoy integrates a positioning and rescue component with GPS positioning, VHF signal transmission, LED warning light, and audible and visual alarm, which can transmit location information in real time and provide clear warnings in various environments, making it convenient for rescuers to quickly and accurately locate the lifebuoy and shorten rescue time.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a ship rescue device, including a life ring body 1, the life ring body 1 including a ring 11, a positioning and rescue component 2 fixedly installed on the top of the ring 11, a plurality of through holes 16 symmetrically opened on the outer side of the ring 11, and two gripping straps 12 symmetrically distributed on the top of the ring 11, both ends of the gripping straps 12 are fixedly connected to elastic bands 13, and one end of the elastic bands 13 is fixedly installed to the top of the ring 11. Two fixing plates 14 are symmetrically distributed on the outer side of the ring 11, and fixing holes 15 are opened through both ends of the fixing plates 14. An anti-ultraviolet layer 10 is provided on the outer wall of the ring 11, and the thickness of the anti-ultraviolet layer 10 is 3-5mm.

[0019] The specific settings and functions of this embodiment are described below: When a crew member falls overboard in an emergency, the crew will quickly deploy the lifebuoy to the area where the person fell overboard. The person can grab the anti-slip grip strap 12 on the outside of the lifebuoy body 11 or the through holes 16 on the outside of the lifebuoy body 11 to stabilize their body. The anti-slip grip strap 12 is made of high-strength nylon material. The grip strap 12 is connected to the lifebuoy body 11 through elastic bands 13 at both ends. The elastic bands 13 are elastic. The grip straps 12 are symmetrically distributed on the lifebuoy body 11, and multiple through holes 16 are symmetrically distributed on the outside of the lifebuoy body 11, which makes it easy for the person in the water to hold on stably and prevents them from slipping out under the impact of waves, thus improving the safety of the rescue. The UV-resistant layer 10 can effectively resist the wear and corrosion of the lifebuoy by the marine environment.

[0020] Example 2: Figure 1 - Figure 4 As shown, a pressure sensor 19 is fixedly installed inside the ring body 11, and multiple buoyancy bladders 17 filled with carbon dioxide gas are evenly distributed inside the ring body 11. One end of the buoyancy bladder 17 is fixedly connected to a sealing valve 18. The pressure sensor 19 is electrically connected to the sealing valve 18. The positioning and rescue component 2 includes a waterproof shell 21, a GPS positioning module 26, a wireless signal transmitter 27, and an audible and visual alarm 22. A battery 25 is installed inside the waterproof shell 21. The GPS positioning module 26 and the wireless signal transmitter 27 are fixedly installed inside the waterproof shell 21. Multiple LED warning lights 23 are fixedly installed on the outside of the waterproof shell 21. A switch 24 is provided on the top of the waterproof shell 21, and the waterproof shell 21 is fixedly installed on the top of the ring body 11. The LED warning lights 23 and the audible and visual alarm 22 are both electrically connected to the battery 25.

[0021] The overall effect of this embodiment is that multiple buoyancy bladders 17 are provided inside the ring body 11. The buoyancy bladders 17 are filled with compressed carbon dioxide gas and isolated from the outside world through the sealing valve 18. If the ring body 11 is damaged due to impact or wear, when the pressure sensor 19 detects a drop in the internal pressure of the ring body 11 (i.e., damage causes a drop in buoyancy), the sealing valve 18 is automatically controlled to open, releasing the carbon dioxide gas in the independent buoyancy bladders 17, causing the buoyancy bladders 17 to expand, supplementing the buoyancy of the life ring, ensuring that the buoyancy always meets the rescue needs, and ensuring that the life ring always maintains sufficient buoyancy to support the person who has fallen into the water. By adding the positioning and rescue component 2, the GPS positioning module 26 can obtain the real-time location information of the lifebuoy, and the wireless signal transmitter 27 can transmit the location information to the receiving terminal on the ship's bridge in real time. It is also compatible with the signal receiving system of the maritime search and rescue center, facilitating accurate positioning by rescue personnel. Simultaneously, the person in the water can activate the LED warning lights 23 and the audible and visual alarm 22 via the switch 24. The LED warning lights 23 are mounted on the waterproof housing 21, with 4 to 6 lights, powered by an internal battery 25, and can operate continuously for at least 72 hours, providing a clear visual marker at night or in low-visibility environments. The audible and visual alarm 22 works in conjunction with the LED warning lights 23. The warning light 23 works synchronously to emit a warning signal, and the sound can be clearly heard within a range of 200m, providing rescuers with accurate positioning and clear identification, further improving the recognizability of the lifebuoy. The lifebuoy integrates GPS positioning, VHF signal transmission, LED warning light 23 and sound and light alarm 22 into a positioning and rescue component 2, which can transmit location information in real time and provide clear warnings in various environments, facilitating rescuers to quickly and accurately locate the lifebuoy and shorten rescue time. This utility model has a reasonable structural design, comprehensive functions, and can effectively adapt to complex maritime environments, providing more reliable and efficient protection for ship rescue, and has high practical value and promotion prospects.

[0022] The method of use and working principle of this device: When a person falls into the water during an emergency, the crew will quickly throw the lifebuoy to the area where the person fell into the water. After the person is thrown, one end of the towing rope is connected to the fixing plate 14 through the fixing hole 15. The towing rope can control the position of the lifebuoy and prevent it from deviating from the target area. The person who fell into the water can grab the anti-slip grip strap 12 on the outside of the lifebuoy 11 or grab the through hole 16 on the outside of the lifebuoy 11 to stabilize their body. This makes it easier for the person who fell into the water to hold on steadily and improves the safety of the rescue. If the lifebuoy 11 is damaged due to impact or wear, when the pressure sensor 19 detects a drop in internal pressure, the automatic control valve 18 opens, releasing carbon dioxide gas from the independent buoyancy bladder 17, causing the buoyancy bladder 17 to expand and supplement the buoyancy of the lifebuoy, ensuring that the lifebuoy always maintains sufficient buoyancy to support the person in the water. By adding the positioning and rescue component 2, the GPS positioning module 26 can obtain the location information of the lifebuoy in real time, and the wireless signal transmitter 27 can transmit the location information to the receiving terminal on the ship's bridge in real time. At the same time, the person in the water can turn on the LED using the switch 24. The lifebuoy features a warning light 23 and an audible and visual alarm 22. The LED warning light 23 provides a clear visual marker at night or in low-visibility environments, while the audible and visual alarm 22 emits a warning signal that can be clearly heard within a 200m range, providing rescuers with precise location and clear identification, further enhancing the lifebuoy's recognizability. The lifebuoy integrates GPS positioning, VHF signal transmission, the LED warning light 23, and the audible and visual alarm 22 into a positioning and rescue component 2. This component can transmit location information in real time and provide clear warnings in various environments, facilitating rapid and accurate location by rescuers and shortening rescue time.
