Description

Technical Field

[0001] This utility model relates to a life jacket with an inflatable radar reflector, belonging to the field of life jacket technology. Background Technology

[0002] In recent years, maritime safety accidents have occurred frequently, with numerous casualties easily occurring when crew members fall overboard and await rescue. Traditional life jackets, as a common type of individual water rescue equipment, play a vital role in maritime transport and production activities such as shipping, marine fisheries, marine engineering, and dock operations. Traditional life jackets are generally equipped with life jacket lights, reflective strips, and whistles, and are designed to keep the wearer afloat. However, rescuers can only locate and identify those in the water by sight or hearing. Limited by factors such as distance and visibility in the search area, those in the water cannot be rescued in a timely manner, resulting in low efficiency in maritime accident search and rescue.

[0003] In addition, some life jackets now incorporate signal reflecting lens mechanisms, such as the existing patent 202023203079.8, which discloses "a kind of life jacket". This utility model relates to a life jacket, including a life jacket body, in which several buoyancy blocks are provided. At least one buoyancy block is a lens structure made of foamed medium material. The lens structure is a cuboid structure, and the lens structure includes a core and several dielectric constant layers. The core is a solid structure, and each dielectric constant layer is a hollow cuboid shell structure. The several dielectric constant layers are arranged to wrap around the core in layers. A reflective sheet is provided on one side of the lens structure, and the side of the reflective sheet that is in contact with the lens structure is its reflective surface. This type of life jacket has the following drawbacks: First, when a person wearing this type of life jacket is in the water, the lens on the shoulder area is basically positioned around the waterline. Due to the influence of wind, waves, and currents, the radar scanning waves emitted by the search and rescue vessel's radar are unlikely to reach the lens position, making it impossible to effectively form an echo image on the search and rescue vessel's screen, thus failing to effectively improve search and rescue efficiency. Second, the lens structure is relatively small, with a small directional radar reflector and a small omnidirectional radar reflector on both shoulders of the life jacket, making it easy to miss some items during the search. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a life jacket with an inflatable radar reflector.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A life jacket with an inflatable radar reflector includes a life jacket body and a radar reflector. The radar reflector has a metal film inside and an inflation port on its surface. The radar reflector is connected to a support rod and has a radar reflector fixing buckle on its surface. A rope is attached to the radar reflector fixing buckle, and the radar reflector is connected to the top of the support rod via the rope.

[0007] Furthermore, the surface of the life jacket body is provided with radar reflector straps, support rod straps, and air pump straps. The radar reflector straps cooperate with the radar reflector, the support rod straps cooperate with the support rod, the bottom of the support rod is fixed to the support rod straps by a buckle, and the air pump straps cooperate with the air pump. The air pump inflates the radar reflector, and the bottom of the air pump is fixed to the buckle of the air pump straps by a rope.

[0008] Furthermore, the life jacket body is equipped with a whistle, which is fixed to the life jacket body by a rope.

[0009] Furthermore, the life jacket body is provided with several reflective strips.

[0010] Furthermore, the life jacket body is provided with three adjustable life jacket straps, and the two ends of the adjustable life jacket straps are connected together by buckles.

[0011] Furthermore, the radar reflector is provided with two sets of metal films inside, each set of metal films including two metal films that intersect perpendicularly, and the metal films are connected to the inner wall of the radar reflector through metal film fixing points.

[0012] The beneficial effects of this utility model are:

[0013] This utility model has a simple structure, scientific design, and is easy to use. It can display large images on radar screens, thus avoiding the problem of missing any search and rescue operations.

[0014] This invention utilizes a lightweight, inflatable radar reflector, which is fixed to the base of a life jacket via a retractable support rod. In an emergency, a person in the water can use an air pump to inflate the radar reflector and raise it to a higher position. Whether it is day or night, the radar of the search and rescue vessel can detect the person wearing the life jacket. This invention improves the radar identification success rate during search and rescue, increases the success rate of search and rescue, and improves the survival rate of people who have fallen into the water.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This utility model provides a life jacket with an inflatable radar reflector, comprising a life jacket body and a radar reflector 1. The radar reflector 1 is an inflatable radar reflector, which is a soft sphere. A metal film 11 is disposed inside the radar reflector 1. An inflation port 13 is provided on the surface of the radar reflector 1, which is an air pump nozzle and also has a mouth inflation function. The radar reflector 1 is connected to a support rod 2, which is a telescopic support rod. A radar reflector fixing hook 12 is provided on the surface of the radar reflector 1, and a rope is provided on the radar reflector fixing hook 12. The radar reflector 1 is connected to the rope. Connected to the buckle at the top of the support rod 2, the radar reflector 1 is fixed to the buckle at the top of the support rod 2 by a rope, which can prevent the radar reflector 1 from being blown away by the wind or waves. This utility model uses a lightweight inflatable radar reflector 1, which is fixed to the ground of the life jacket by the telescopic support rod 2. In an emergency, the person in the water can use the air pump 4 to inflate the radar reflector 1 and raise the radar reflector 1 to a higher position. Whether it is day or night, the radar of the search and rescue vessel can detect the person in the water wearing the life jacket. The device of this utility model improves the radar identification success rate during the search and rescue process, increases the search and rescue success rate, and improves the survival rate of people who fall into the water.

[0024] See Figure 1-5 The surface of the life jacket body is provided with radar reflector straps 6, support rod straps 9, and inflation pump straps 10. The radar reflector straps 6 cooperate with the radar reflector 1, securing the deflated and folded radar reflector 1. The support rod straps 9 cooperate with the support rod 2, with the bottom of the support rod 2 fixed to the support rod straps 9 by buckles. The support rod 2 is attached to the support rod straps 9, used to support the inflated radar reflector 1 to a higher position in emergency situations (e.g., ...). Figure 2 As shown, the support rod 2 can be effectively fixed to the life jacket body in wind and waves by the buckle at the bottom of the support rod 2. The air pump strap 10 works with the air pump 4. The air pump 4 is a small, rechargeable, and waterproof air pump that can emit light. The air pump 4 inflates the radar reflector 1. The bottom of the air pump 4 is fixed to the buckle of the air pump strap 10 by a rope to prevent the air pump 4 from being blown away by the wind or washed away by the waves.

[0025] See Figure 1-5 The life jacket is equipped with a whistle 5, which is fixed to the life jacket by a rope. The whistle can emit a distress sound, making it easy for search and rescue personnel to detect.

[0026] See Figure 1-5The life jacket body is provided with several reflective strips 3, which can reflect the light shone by the search and rescue personnel, making it easier for the search and rescue personnel to notice.

[0027] See Figure 1-5 The life jacket body is provided with three adjustable life jacket straps 7. The two ends of the adjustable life jacket straps 7 are connected together by buckles 8. The user can securely put on the life jacket body by using the adjustable life jacket straps 7 and the buckles 8 on the adjustable life jacket straps 7.

[0028] See Figure 1-5 The radar reflector 1 has two sets of metal films 11 inside. Each set of metal films 11 includes two perpendicularly intersecting metal films 11. The metal films 11 are connected to the inner wall of the radar reflector 1 through metal film fixing points 14. After the radar transmitter 1 is inflated, the two sets of metal films 11 are respectively located on both sides inside the radar reflector 1. Each set of metal films 11 is intersected to form four three-sided right-angled reflection spaces, such as... Figure 5 As shown, the two groups together form eight three-sided right-angled reflection spaces.

[0029] When in use, after the radar reflector falls into the water at sea, untie the air pump strap 10, connect the air pump 4 to the radar reflector air inlet 13, untie the radar reflector strap 6, loosen the radar reflector 1, and fill the radar reflector 1 with gas to form a spherical shape. Inside the radar reflector 1, there are vertically cross-fixed and repeatedly foldable metal films 11. After the radar reflector 1 is fully inflated, the radar reflector 1 is formed. The metal films 11 on both sides of the radar reflector 1 unfold, forming four three-sided right-angle reflection spaces, which together constitute eight three-sided right-angle reflection spaces, enabling the radar reflector 1 to reflect radar waves at a long distance. At this time, the preparation process for using the radar reflector is completed.

[0030] Connect the extendable support rod 2 to the radar reflector fixing hook 12, raise the support rod 2, and raise the radar reflector 1 to a higher position (e.g., Figure 2 As shown), during the search and rescue process using radar, the radar waves emitted by the rescuers reach the metal film 11 that can reflect radar waves. Due to the characteristics of the three-sided right-angle reflection space, the radar waves are reflected back along the direction of incidence. The radar reflection echo is much stronger than the echo intensity of the surrounding objects, and a strong echo signal is displayed on the radar screen of the search and rescue vessel, increasing the probability of the person who fell into the water being detected by radar.

[0031] If rescuers arrive nearby, the person who fell into the water can blow whistle 5 to attract their attention. If the fall occurred at night, the light on the air pump 4 can be turned on to increase the chances of being found.

[0032] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
