Marine rescue equipment

Abstract

The application discloses offshore rescue equipment and belongs to the technical field of personal water safety equipment. The equipment comprises a front buoy binding mechanism as an inner layer and a rear buoy binding mechanism as an outer layer. The inner and outer layer mechanisms are combined through multi-point cooperation of shoulders, backs and waists and are locked in a stable closed loop through a crotch belt. The core innovation is that a set of precise and detachable mechanical linkage connection structures are arranged between the inner and outer waist belts. When the equipment is pulled upward during rescue, the structures can intelligently convert passive pulling force into active radial inward tightening force, so that the inner waist belt is automatically tightened, thereby greatly enhancing the binding force between the equipment and the user's body. The unique double-layer closed loop structure and dynamic self-locking mechanism of the application fundamentally eliminate the risk of rescue slipping, the structure is stable and reliable, and the safety and success rate of offshore rescue are significantly improved.

Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of personal water safety equipment, and particularly relates to a structure safe and dynamic self-locking rescue equipment. BACKGROUND

[0002] Personal Flotation Device (PFD), commonly known as life jacket, is the most basic and important equipment to protect personal life safety in water activities, navigation, offshore operations and rescue operations. The core design concept of traditional life jacket is to provide sufficient buoyancy for the fallen person to float on the water surface and wait for rescue. It usually adopts a vest structure, with high buoyancy material (such as closed-cell foam) built-in, and is fixed by several simple belts and buckles.

[0003] However, for a long time, such traditional life jackets have exposed several fatal design defects in real, especially in emergency rescue scenarios:

[0004] 1. "Fatal slip" risk in the rescue process: This is the most serious and fundamental pain point in the prior art. When the rescuer (e.g. from a ship or a helicopter) tries to hoist the fallen person by pulling the life jacket, the huge, vertically upward pulling force will act on the shoulder of the life jacket. Since the lower part of the traditional life jacket is open, its structure is like an open bag, and the fallen person is the object in the bag. Under the huge pulling force, the life jacket is easy to slip upward from the relatively narrow shoulder of the fallen person, causing the fallen person to "shed his skin" and fall out of the life jacket, directly causing the rescue to fail, and even causing more serious injuries due to secondary falling or impact.

[0005] 2. "Secondary injury" to the rescued person: Even if the life jacket does not completely slip, the huge pulling force will be highly concentrated in the two narrow areas of the fallen person's armpit and shoulder. This high pressure can cause serious crushing, which may cause soft tissue contusion and nerve compression, causing great pain and additional physical damage to the already weak or injured fallen person.

[0006] 3. Unstable floating posture, with safety hazards: The fit of the traditional life jacket is often not good. In the water, especially in rough seas, the life jacket is easy to float up or shift, which may float up to the face of the user, block the mouth and nose, and hinder breathing, which is particularly dangerous for unconscious persons.

[0007] 4. The inherent contradiction between comfort and safety: in order to prevent slipping as much as possible, the user must tighten the straps of the traditional life jacket very tightly, which causes it to be extremely hot and constricting to wear, with extremely poor comfort. Considering that this type of equipment can be used by both military and civilian personnel, the poor comfort of this equipment causes many people who need to work near the water or at sea for a long time (such as fishermen, the navy, coast guards, platform workers) to have a serious "wear resistance", which greatly reduces the daily wear rate of the equipment and lays the foundation for safety hazards.

[0008] Therefore, there is an urgent need in the art for a completely new design that can completely eliminate the risk of slipping from the structure, scientifically disperse the rescue stress, and at the same time take into account the safety posture and wearing comfort of the user. SUMMARY

[0009] The purpose of the present application is to overcome the above-mentioned defects of the prior art and provide a marine rescue equipment. The equipment, through the unique double-layer binding structure, the mechanical closed-loop design of the key parts and the intelligent response dynamic self-locking mechanism, aims to fundamentally solve the problem of slipping of the life jacket during the rescue lifting process, avoid causing secondary injury to the rescued person, and at the same time ensure that the fallen person has a safe floating posture and good wearing experience, thereby greatly improving the success rate of marine rescue and the survival rate of the rescued person.

[0010] The above technical purpose of the present application is achieved by the following technical scheme: a marine rescue equipment, comprising:

[0011] a front buoy binding mechanism, comprising a front buoy for providing front buoyancy, an inner back part fitted to the back of the user, and an inner back strap connecting the front buoy and the inner back part; the front buoy binding mechanism further comprises a double-head buckle provided on the front face of the front buoy, a chest strap extending from the inner back part and being connected to each other through the double-head buckle, and an inner waist strap extending from the inner back part, the end portions of which can be connected to each other to wrap around the waist of the user;

[0012] a rear buoy binding mechanism, comprising a rear buoy for providing rear buoyancy, an outer back strap connecting the rear buoy and the front buoy and covering the inner back strap, an outer back part connected to the rear buoy and covering the inner back part, and an outer waist strap extending from the outer back part;

[0013] wherein the front buoy binding mechanism serves as the inner layer, the rear buoy binding mechanism serves as the outer layer, and the outer waist strap and the inner waist strap are mutually fitted and detachably connected.

[0014] Further, the front buoy is provided with a material bag.

[0015] Further, the front buoy is provided with a positioning module.

[0016] Further, a crotch belt is provided, one end of which extends from the lower part of the outer back part and the other end passes through the crotch of the user and is detachably connected to the front buoy through a single-head buckle.

[0017] Further, the outer side of the inner back part is provided with a first adhesive part and the inner side of the outer back part is provided with a second adhesive part matched with the first adhesive part.

[0018] Further, a reflective strip is provided on the outer back belt.

[0019] Further, the detachable connection between the inner waist belt and the outer waist belt is achieved through the following structure:

[0020] A positioning strip extending along the length direction of the inner waist belt is provided on the outer side of the inner waist belt, which provides a stable reference surface for the inner waist belt.

[0021] A turning strip is fixed on the outer side of the inner waist belt through the positioning strip, which extends downward at a fixed angle with the outer side of the inner waist belt along the length direction of the inner waist belt.

[0022] An end of the turning strip away from the inner waist belt is provided with a clamping strip.

[0023] An embedding strip is provided on the outer waist belt, which is matched in shape and size with the clamping strip to achieve embedded connection.

[0024] When the equipment is pulled upward, the outer waist belt pulls the clamping strip upward through the embedding strip, so that the turning strip has a tendency to turn outward, which generates a radial inward gathering force to tighten the inner waist belt on the waist of the user.

[0025] Compared with the prior art, the present application has the following beneficial effects:

[0026] 1. The present application ensures absolute anti-falling performance through three mechanisms: first, the crotch belt forms the most basic and effective physical closed loop, which fundamentally eliminates the possibility of the equipment slipping off the user; second, the front and rear buoys form a strong shoulder bearing structure through the connection of the outer back belt; most importantly, the dynamic self-locking mechanism of the inner and outer waist belts can convert passive pulling force into active and enhanced tightening force in the most dangerous upward pulling moment, and the combination of the equipment and the human body is not weakened but increased. This completely overturns the fatal defect of the traditional life jacket that gets looser and looser.

[0027] 2、Traditional life jackets concentrate all the pulling force on the armpit. But the present invention, through the double-layer structure and the large-area fitting on the back, evenly disperses the upward pulling force from the "point" or "line" stress to the "surface" of the user's entire back and torso. This greatly reduces the local pressure and avoids secondary injuries such as crush injuries and nerve damage caused by stress concentration.

[0028] 3、The present invention sets the rear float block at the critical position behind the user's neck. Whether the user is conscious or not, the float block can forcibly hold up the user's head like a life-saving pillow, making the face tilt backward and keeping the mouth and nose above the water surface. This ensures the smoothness of the respiratory tract, the life passage, and gains the most valuable time for rescue.

[0029] 4、The present invention successfully solves the contradiction between comfort and safety in traditional life jackets by decomposing the equipment into an inner layer (comfort layer) and an outer layer (structural layer). The inner layer can use skin-friendly and breathable materials to ensure daily comfort, thereby greatly improving the user's willingness to wear; the outer layer can use the most solid and durable materials without compromise to carry all rescue functions, realizing military and civilian dual use. This design innovation makes the equipment not only a reliable lifesaving tool but also a daily equipment that users are willing to wear for a long time. BRIEF DESCRIPTION OF DRAWINGS

Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0042] Reference Figure 1The offshore rescue equipment adopts a double-layer modular design, which includes a front buoy binding mechanism as an inner layer responsible for comfortable fitting and a rear buoy binding mechanism as an outer layer responsible for structural force bearing and core safety functions.

[0043] Referring to Figures 1-3 The front buoy binding mechanism as the inner layer directly contacting the user is an inner layer vest structure, wherein the core component is a front buoy 1. The inner filler of the front buoy 1 can be closed-cell polyethylene foam (EPE) with high buoyancy, flexibility and impact resistance, and is wrapped by skin-friendly neoprene or lycra fabric, which ensures comfort when in contact with the body and provides the user with the buoyancy of the front core to prevent the body from leaning forward. In order to solve the technical problem that the fallen person in a weak state has difficulty in obtaining survival supplies, a material bag 2 is arranged at the shoulder clavicle area of the front buoy 1, close to the user's mouth. The material bag 2 can contain a high-frequency survival whistle, a small signal mirror and a retractable drinking tube, so that the user can perform survival or water replenishment operation without using hands, greatly improving the survival probability of the fallen person. At the same time, in order to solve the technical problem of "difficult search and slow positioning" in traditional rescue, the equipment also integrates a positioning module 3, which is built-in with a positioning chip supporting GPS, Beidou and other systems and a 406MHz personal positioning beacon antenna, and has a water-activated automatic activation function, which can emit accurate coordinates to the international search and rescue satellite system, thereby reducing the search range from sea level to meter level, and significantly shortening the search time.

[0044] The main components constituting the inner layer vest structure also include an inner back strap 6 and an inner back part 7. The upper end of the inner back strap 6 is connected with the front buoy 1, used to be placed on the user's shoulders. The inner back part 7 is connected with the other end of the inner back strap 6, used to be fitted on the user's back. In order to solve the problem of "wearing resistance" caused by equipment heat in the prior art, the inner lining of the two components adopts three-dimensional mesh spacer fabric, which realizes efficient ventilation and moisture conduction through its three-dimensional hollow structure, thereby ensuring dryness and comfort during long-term wearing, and effectively improving the daily wearing rate of the equipment. Two independent elastic nylon chest straps 8 extend from the left and right wings of the inner back part 7, respectively, which are connected with each other through a quick plug-in double-head buckle 4 made of polyoxymethylene (POM) material arranged on the front of the front buoy 1, forming a stable chest fixing structure, so as to firmly fix the front buoy on the user's chest to prevent it from shaking or jumping up in the wind and waves. The inner waist strap 9 extending from the inner back part 7 is used to wrap and preliminarily fix the user's waist.

[0045] Referring to Figure 1 and Figure 4, the rear float binding mechanism as the outer layer is the force bearing and safety core of the equipment. The key component is the rear float 11, which is ergonomically designed to accurately fill the space behind the user's neck. The buoyancy point provided by the rear float 11 is located above the center of gravity of the upper body, generating a righting moment that causes the head of the fallen person, especially the unconscious person, to tilt backward and lift the mouth and nose out of the water. This solves the problem of suffocation caused by the forward tilt of the head due to loss of strength or unconsciousness, ensuring the smoothness of the airway. As the core load-bearing component, the outer harness 12 is made of ultra-high molecular weight polyethylene (UHMWPE) fiber fabric, which has a high strength-to-weight ratio. It connects the rear float 11 and the front float 1, forming a "force-bearing bridge" across the shoulder, directly bearing the lifting force during rescue.

[0046] To maximize the probability of being discovered by the fallen person under any light conditions, the invention adopts a combination of active and passive visual identification schemes. On the one hand, the outer harness 12, as the most easily observed shoulder position of the core load-bearing component, is equipped with a high-brightness reflective strip 13. The reflective strip 13 can reflect the light source such as the searchlight of the rescue party at night or in low light environments, forming a strong reflection and achieving passive warning. On the other hand, the signal light device integrated into the positioning module 3 on the front float 1 complements the reflective strip 13. The signal light device can actively emit high-frequency flashing signals, especially in harsh weather or darkness without external light sources, attracting the attention of search and rescue personnel. By combining the passive reflection of the reflective strip 13 and the active light of the signal light, the equipment establishes a full-time, long-distance visual identification system, greatly improving the probability of being discovered by the fallen person at night or in adverse sea conditions, thereby gaining valuable time for rapid search and rescue.

[0047] To firmly combine the inner and outer layers into a whole, the upper end of the outer back 14 is connected to the rear float 11, which covers the inner back 7 when worn. The inner side of the outer back 14 and the outer side of the inner back 7 are respectively provided with industrial-grade hook and loop fasteners, namely the second adhesive part 15 and the first adhesive part 10, which can be widely attached. This "surface" connection aims to solve the technical problems of stress concentration and unstable structure in traditional equipment, which can evenly distribute stress when the equipment is stressed and increase the shear resistance between the inner and outer layers. To provide basic "bottom" protection for the entire anti-falling system, a crotch strap 17 extends from the lower part of the outer back 14 and is connected to the front float binding mechanism through a single-head buckle 5, forming a closed physical loop that passes through the user's crotch, "anchoring" the entire equipment with the lower part of the body center of gravity.

[0048] In addition, in some embodiments, a dynamic self-locking connection structure is arranged between the inner and outer waist belts, which aims to solve the technical problem that the conventional waist belt becomes loose or fails when being pulled. The structural basis is that a positioning strip 901 as a semi-rigid base is fixed on the outer side of the inner waist belt 9 to provide a reliable reference surface for the subsequent lever structure; a flip strip 902 is fixed on the inner waist belt 9 through the positioning strip 901 and forms an accurate, downwardly inclined fixed included angle with the outer side of the inner waist belt; the end of the flip strip is an integrally formed C-shaped clamping strip 903, and the outer waist belt 16 has a matching embedded strip 1601. The dynamic response working principle is as follows: when rescuing, the upward pulling force is transmitted to the outer waist belt 16, which pulls the C-shaped clamping strip 903 upward through the embedded strip 1601; then, due to the inclined lever structure of the flip strip 902, the upward pulling force will force it to have an upward and outward turning deformation trend around the fulcrum; finally, since the waist belt is wrapped around the user's waist, this "outward turning" trend will be limited by the circumference of the waist belt, thereby converting the upward linear pulling force into a radial gathering force perpendicular to the waist belt and pointing to the center of the body. The greater the pulling force, the stronger the inward tightening force, so that the equipment has a dynamic response capability, which can convert the pulling force into enhanced locking force at critical moments, realizing the dynamic self-locking effect of pulling tighter.

[0049] In summary, the present application effectively partitions and integrates comfort, buoyancy guarantee, structural bearing and emergency function through the modular design and collaborative combination of the front and rear float block binding mechanisms. Through the outer shoulder strap 12, the first and second adhesive parts 10 and 15 on the back, the inner and outer waist belts 9 and 16 on the waist, and the crotch belt 17 at the bottom, a full- range, mechanically closed-loop locking system is constructed, which can be used for both military and civilian purposes. In particular, the dynamic self-locking connection structure between the inner and outer waist belts endows the equipment with the performance of actively enhancing the locking force at critical moments, thereby solving all the defects in the prior art.

[0050] The above describes only the specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or replacements within the technical range disclosed by the present application can be easily thought of by those skilled in the art, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
