Description

Technical Field

[0001] This utility model relates to the field of marine life jacket technology, and specifically discloses a marine life jacket that is convenient for waiting for rescue. Background Technology

[0002] Marine life jackets are crucial equipment for ensuring the safety of personnel working and sailing on water. Currently, the main function of most common life jackets on the market is to provide sufficient buoyancy so that the head of a person falling into the water remains above the surface, preventing drowning.

[0003] However, in actual maritime accidents, those who fall into the water are often unconscious due to injury, hypothermia, or exhaustion, making it difficult for them to maintain their balance, leading to their face being submerged and choking or drowning. Furthermore, on the vast and harsh sea, those in the water are small targets, making them difficult for rescuers to spot; traditional methods of distress signals such as whistles and manual signal lights are of limited effectiveness when the victim is unconscious or in nighttime conditions, and they cannot provide precise location information, significantly delaying crucial rescue time. Some existing life jackets lack effective support for the head and hips, failing to allow the body to automatically maintain a stable supine position. Therefore, a new type of marine life jacket that facilitates waiting for rescue is needed to address this problem. Utility Model Content

[0004] This utility model proposes a marine life jacket that facilitates waiting for rescue. The specially designed headrest and support pad on the back provide support for the user's head, neck, waist, and hips, respectively. Furthermore, the multi-functional distress structure greatly improves search and rescue efficiency and success rate.

[0005] This utility model is implemented as follows: a marine life jacket for convenient waiting for rescue, including a life vest, the back of which is provided with a support structure for supporting the user's head, neck and waist and hips; the front of the life vest is provided with a multi-functional distress signal structure for sending distress signals and precise location.

[0006] The support structure includes a support piece sewn to the rear end of the life vest, and a headrest and support pad connected to the upper and lower parts of the support piece can be detached and removed respectively by two sets of buckles;

[0007] The multi-functional distress signal structure includes two sets of LED light strips sewn to the front of the life vest, and reflective strips sewn to the surface of the life vest and arranged in an alternating pattern with the LED light strips;

[0008] A GPS beacon is provided on the rear end face of the carrier plate, and the GPS beacon has a built-in water-sensitive sensor.

[0009] As a preferred embodiment of this utility model of a marine life jacket for convenient waiting for rescue, the side waist of the inner wall of the life jacket is provided with a waterproof compartment, and a battery module is placed inside the waterproof compartment.

[0010] As a preferred embodiment of this utility model for a marine life jacket that facilitates waiting for rescue, the support pad has first fixing straps sewn on both sides, and two U-shaped connecting sleeves are fixedly connected to the lower end face of the support pad, with second fixing straps sewn on the outer walls of the two connecting sleeves.

[0011] As a preferred embodiment of this utility model for a marine life jacket that facilitates waiting for rescue, the life vest, headrest, and support pad are all provided with a buoyancy material layer inside.

[0012] As a preferred embodiment of this utility model for a marine life jacket that facilitates waiting for rescue, the battery module is electrically connected to the LED light and controlled by a control button located on the inner wall of the life jacket.

[0013] As a preferred embodiment of this utility model of a marine life jacket for convenient waiting for rescue, the buoyancy material layer is made of closed-cell polyethylene foam.

[0014] The beneficial effects of this utility model are:

[0015] 1. The specially designed headrest and support pad on the back provide support for the user's head, neck and waist, and utilize the buoyancy of the internal buoyancy material to ensure that the body of the person who has fallen into the water can automatically assume a stable supine position in the water, even if the person is in a state of impaired consciousness. This effectively ensures that the mouth and nose are above the water surface, greatly reducing the risk of choking and drowning.

[0016] 2. By using LED light strips, it can emit high-frequency flashing bright light visible from several kilometers away, ensuring rapid detection at night. The staggered reflective strips can reflect dazzling light during the day or when illuminated by searchlights. Utilizing complementary light, it can achieve all-weather distress signaling. It integrates a GPS beacon, which automatically activates after entering the water via a water-sensitive sensor, continuously sending precise location information to the Beidou satellite system, enabling rescue forces to travel in a straight line to the target point, greatly improving search and rescue efficiency and success rate.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0023] Please see Figure 1-3 A marine life jacket designed for convenient waiting for rescue includes a life vest 1. The life vest 1 has a support structure on the back for supporting the user's head, neck, waist, and hips. The life vest 1 also has a multi-functional distress signal structure on the front for sending distress signals and precise location information.

[0024] The support structure includes a support piece 4 sewn to the rear end of the life vest 1, and a headrest 5 and a support pad 6 connected to the upper and lower parts of the support piece 4 can be detached and removed by two sets of buckles 401.

[0025] The multi-functional distress signal structure includes two sets of LED light strips 2 sewn to the front of the life vest 1, and reflective strips 101 sewn to the surface of the life vest 1 and arranged alternately with the LED light strips 2;

[0026] A GPS beacon 7 is provided on the rear end face of the carrier plate 4, and the GPS beacon 7 has a built-in water sensor.

[0027] In this embodiment: when a ship is in distress and personnel fall into the water, this life jacket should be put on immediately. After entering the water, the back support structure (headrest 5 and support pad 6) will support the user's head, neck and waist and hips, so that the body is in a relatively stable supine position in the water. Even if the user is unconscious due to injury or exhaustion, the face can be effectively prevented from being submerged in the water.

[0028] When a person falls into the water at night, the user can activate LED light strip 2 (LED light strip 2 uses a potting process, encapsulating it with epoxy resin to ensure all electronic components are sealed, achieving an IP68 protection rating, capable of withstanding water depths of 10 meters and prolonged immersion; the outer plastic material of the light strip is marine-grade polyurethane, resistant to salt spray and ultraviolet rays to cope with harsh marine environments), which will emit a high-frequency flashing bright light, clearly visible from several kilometers away. During the day, or when the searchlight of a rescue helicopter sweeps across the sea, the reflective strip 101 on the life jacket will immediately reflect a dazzling light, quickly attracting the attention of rescuers even when it is faintly visible among the waves;

[0029] After the life jacket enters the water, GPS beacon 7 automatically activates via a water-sensitive sensor (e.g., using a normally open water-sensitive switch installed at an exposed position on the beacon's outer shell), continuously transmitting precise location information to the BeiDou satellite system. Rescue vessels can then navigate in a straight line to the target location based on this information, greatly improving search and rescue efficiency and success rate.

[0030] As a technical optimization of this utility model, a waterproof compartment is provided on the side waist of the inner wall of the life vest 1, and a battery module 3 is placed inside the waterproof compartment.

[0031] In this embodiment, battery module 3 (a lithium thionyl chloride battery. This type of battery has the characteristics of high energy density, extremely low self-discharge rate (annual self-discharge rate <1%), and wide operating temperature range (-55℃ to +85℃), making it very suitable for life-saving equipment that needs to be stored for a long time and used in emergencies. It can ensure that the LED strip and GPS beacon 7 can work continuously for tens of hours) is placed in an independent waterproof compartment, which effectively isolates the risk of seawater corrosion and short circuits, ensuring that electronic devices such as LED strip 2 and GPS beacon 7 have a stable power supply for a long time in harsh marine environments. When periodic inspections are required or the battery is depleted, the sealed cover of the waterproof compartment can be opened to remove battery module 3 for testing or replacement.

[0032] As a technical optimization of this utility model, the support pad 6 has a first fixing band 601 sewn on both sides, and two U-shaped connecting sleeves 602 are fixedly connected to the lower end face of the support pad 6. The outer walls of the two connecting sleeves 602 are sewn with a second fixing band 603.

[0033] In this embodiment: After the user puts on the life jacket, they first wrap the first securing straps 601 on both sides around their body and secure them to the corresponding buckles on the front of the vest, tightening them to stabilize the lateral position of the support pad 6. Then, they pass the two second securing straps 603 under their thighs and secure them to the front or side, so that even if they encounter large waves, the support pad 6 will not float upwards, thus reliably supporting the user's buttocks and maintaining their balance in the water.

[0034] As a technical optimization of this utility model, the life vest 1, the headrest 5, and the support pad 6 are all provided with a buoyancy material layer inside.

[0035] In this embodiment: After the person in the water puts on the life jacket, the life vest 1 provides the main buoyancy, and the buoyancy material inside the headrest 5 gives it upward buoyancy in the water, helping to support the neck and ensuring that the mouth and nose are above the water surface. The buoyancy of the support pad 6 makes the buttocks float, working in conjunction with the headrest 5 to allow the body to naturally maintain an ideal life-saving posture with the head tilted back and the waist floating in the water, effectively preventing choking caused by the body being upright or leaning forward in the water.

[0036] As a technical optimization of this utility model, the battery module 3 is electrically connected to the LED light strip 2 and controlled by the control button 201 located on the inner wall of the life vest 1.

[0037] In this embodiment: After falling into the water, the user only needs to put their hand inside the front of the life vest 1 to touch the control button 201. Pressing the button will immediately cause the LED light strip 2 to flash (the control button 201 is a waterproof button switch, which forms a circuit with the positive and negative terminals of the battery module 3 and the LED light strip 2 through wires).

[0038] As a technical optimization of this utility model, the buoyancy material layer is a closed-cell foam polyethylene material.

[0039] In this embodiment: the closed-cell structure makes it almost non-absorbent, and can maintain stable buoyancy for a long time; the material is lightweight and will not add too much weight to the life vest 1; it has good flexibility and durability and can withstand repeated compression without being easily damaged.

[0040] The working principle and usage of this utility model are as follows: When a ship is in distress and personnel fall into the water, immediately put on this life vest 1. Upon entry into the water, the closed-cell foam polyethylene buoyancy material layer inside the life vest 1, headrest 5, and support pad 6 immediately provides sufficient buoyancy. At the same time, the back support structure begins to work: the headrest 5 supports the neck, and the support pad 6 supports the waist and hips. Under the buoyancy of the water, the user's body is automatically adjusted and stabilized in a supine position with the face upward, effectively preventing water inhalation.

[0041] After falling into the water, the user reaches inside the front of the life jacket and presses control button 201 to activate the two sets of LED light strips 2 on the front. The light strips emit a high-frequency flashing bright light, forming a significant visual signal at night. At the same time, the reflective strips 101 on the life jacket will produce a strong reflection during the day or when encountering rescue lights.

[0042] Once the life jacket enters the water, the water-sensitive sensor inside GPS beacon 7 is triggered, and the device automatically starts up, continuously sending out distress signals containing precise location information through the BeiDou satellite navigation system.

[0043] After receiving GPS location information, rescue units (such as rescue boats and helicopters) can accurately navigate to the area where the person has fallen into the water. By observing the strong LED light or the reflected light from the reflective strips 101 on the sea surface, they can quickly locate and rescue the person. Throughout the process, an independent waterproof battery compartment provides stable and long-lasting power to all electronic devices.
