Description

Technical Field

[0001] This utility model belongs to the field of underwater operation and rescue technology, specifically relating to a rescue vest for deep-water workers. Background Technology

[0002] Deep-sea vehicles, including submarines, play a crucial role in deep-sea exploration under today's high-tech conditions, serving as powerful tools for underwater operations. However, given the exceptionally complex marine environment, especially the deep-sea environment, and the highly sophisticated nature of modern deep-sea vehicles, operators and maintenance personnel face significant risks during deep-sea operations. For example, a malfunction or attack on a deep-sea vehicle can lead to a significant probability of shutdown, making deep-sea rescue a complex and lengthy process. Summary of the Invention

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a rescue vest for deep-water workers. Through the rational design of the component structure, it solves the rescue problem for deep-water workers when facing submersible shutdown temperatures and oxygen system depletion.

[0004] To achieve the above objectives, the technical solution adopted by this utility model includes:

[0005] A deep-water rescue vest includes a first and second section located on the left and right chests, a third section located on the abdomen, a fourth section encircling the neck, a fifth section located on the back shoulder blades, and a sixth and seventh section located on the sides of the chest and abdomen, respectively. Each section is equipped with a heat-generating and oxygen-producing unit. The heat-generating and oxygen-producing unit includes a sealed cavity, within which are a first reaction chamber and a second reaction chamber. Both the first and second reaction chambers are sealed with an insulating membrane. The sealed cavity outside the first and second reaction chambers is a vacuum reaction chamber.

[0006] Preferably, the sealed cavity consists of an inner insulation layer and an outer waterproof layer.

[0007] Preferably, calcium peroxide is injected into the first reaction chamber and water is injected into the second reaction chamber.

[0008] Ideally, each partition should be independent of the others.

[0009] Compared with the prior art, the advantages of this utility model are:

[0010] (1) The deep-water rescue vest of this utility model can be used by manually breaking the isolation film of the first reaction chamber and the second reaction chamber with external force. The first reaction chamber and the second reaction chamber are connected to the vacuum reaction chamber and a chemical reaction is generated in the vacuum reaction chamber, which generates heat and oxygen. When applied to the deep-water rescue vest, the heat generation and oxygen generation respectively realize the vest's heat preservation function and buoyancy function. At the same time, the generated oxygen can be reused, avoiding the life-saving problem when the submersible stops at a low temperature and the oxygen system disappears.

[0011] (2) The deep-water rescue vest of this utility model has independent compartments. When used by deep-water workers, heat generation is carried out in different compartments according to the needs of different parts, so that heat and other functions can be controlled. At the same time, the heat generation in different compartments can save heat, extend the functional time, and give more opportunities for rescue. Attached Figure Description

[0021] The utility model is not limited to the following specific embodiments. All equivalent modifications made based on the technical solution of this application fall within the protection scope of this utility model.

[0022] It should be noted that the directional terms mentioned in this article, such as "inner cavity," "inner," and "outer," are consistent with the specific directions on the paper in the accompanying drawings or the corresponding directions of the space shown in the drawings; all components and devices in this utility model, unless otherwise specified, adopt components and devices known in the prior art.

[0023] Example

[0024] This embodiment discloses a rescue vest for deep-water workers, including a first section a and a second section b located on the left and right chests respectively, a third section c located on the abdomen, a fourth section d surrounding the neck, a fifth section e located on the back shoulder blades, a sixth section f located on the side chest and a seventh section g located on the abdomen respectively, and each section is equipped with the heat generation and oxygen production unit disclosed in Embodiment 1.

[0025] Its function is as follows: each zone is independent of the others, and deep-water workers can generate heat in different zones according to the needs of different parts, so that the heat and other functions can be controlled; at the same time, zoned heat generation can save heat, extend the function time, and buy more opportunities for rescue.

[0026] As shown in the figure, the rescue vest in this embodiment is made of commercially available waterproof and high-temperature resistant fabrics according to ergonomic principles. Its structure not only protects the main body of the chest and abdomen, but also protects the neck, armpits and other parts of the body.

[0027] The heat-generating oxygen unit of this embodiment includes a sealed cavity 1, and a first reaction cavity 2 and a first reaction cavity 3 are provided inside the sealed cavity 1. The first reaction cavity 2 and the second reaction cavity 3 are sealed with an isolation film to seal their inner cavities. The sealed cavity 1 outside the first reaction cavity 2 and the second reaction cavity 3 is a vacuum reaction cavity 4.

[0028] Its function is as follows: When in use, the isolation membrane between the first reaction chamber 2 and the second reaction chamber 3 is manually broken by external force, and the first reaction chamber 2 and the second reaction chamber 3 are connected to the vacuum reaction chamber 4 and a chemical reaction is generated in the vacuum reaction chamber 4, which generates heat and produces oxygen. When applied to the rescue vest of deep-water workers, it realizes the heat preservation function of the vest. At the same time, the oxygen generated can be reused, avoiding the rescue problem when the submersible stops in deep water and the oxygen system disappears.

[0029] The oxygen generation process disclosed in this embodiment can also serve as a flotation function during rescue operations.

[0030] The oxygen-generating function of the rescue vest in this embodiment is mainly used in scenarios where a sealed deep-sea submersible malfunctions during underwater operations and is unable to provide oxygen to its personnel. In such situations, as the oxygen inside the submersible gradually depletes, tearing the vest increases the oxygen content inside, temporarily alleviating the oxygen deficiency and buying time for rescue operations.

[0031] In this embodiment, both the first reaction chamber 2 and the second reaction chamber 3 are sealed with an isolation film. Specifically, CaO2 is wrapped in the isolation film inside the first reaction chamber 2, and H2O is wrapped in the isolation film inside the second reaction chamber 3. The two chemical substances are wrapped in the isolation film and placed in the same vacuum reaction chamber 4. By manually applying external force to the outside of the vacuum reaction chamber 4 through rubbing or pressing, the isolation films of the two chemical substances are damaged, so that a chemical reaction occurs in the vacuum reaction chamber 4 to generate heat and produce oxygen.

[0032] Those skilled in the art will understand that hypothermia in deep-sea personnel does not occur in a short period of time. For example, when a submersible stops in deep water, the temperature and oxygen systems disappear, but the personnel are not in contact with seawater. Based on the function and structure of the deep-sea submersible, its internal temperature can still be maintained for a considerable period. The purpose of this application is to avoid violent and complex chemical reactions, especially when equipping the vest in a sealed deep-sea submersible. Violent chemical reactions would actually compromise the safety of the submersible. The reaction between CaO2 and H2O is stable, non-toxic, and has the characteristic of long-term oxygen release. The purpose of this application is to allow the deep-sea personnel rescue vest to react slowly, thus ensuring sustained and safe heating to achieve a heat preservation effect.

[0033] In this embodiment, the isolation film of the first reaction chamber 2 and the second reaction chamber 3 can be made of commonly used thin plastic bag material. The vacuum reaction chamber 4 can be made of aluminum foil fiberglass cloth, which is airtight, watertight, and has good sealing performance. The thickness can be less than 1 mm, which is a commonly used fire-fighting high-temperature resistant material. This ensures that the isolation film will not be damaged during daily use when it is used in rescue vests. At the same time, the vacuum reaction chamber 4 is manually vacuumed by means of rubbing / pressing, which causes the isolation film of the first reaction chamber 2 and the second reaction chamber 3 to be damaged.

[0034] The sealed cavity 1 disclosed in this embodiment consists of an inner insulation layer 1-1 and an outer waterproof layer 1-2. The inner insulation layer 1-1 prevents burns caused by excessively high temperatures, while the outer waterproof layer 1-2 prevents internal chemical reactions caused by moisture. The inner insulation layer 1-1 in this embodiment can be made of aluminum foil fiberglass cloth, which is airtight, waterproof, and has good sealing properties. Its thickness can be less than 1 mm, making it a commonly used fire-fighting and high-temperature resistant material. It can isolate high-temperature heat sources while conducting a temperature suitable for the human body.

[0035] The specific instructions for using the deep-water rescue vest disclosed in this embodiment are as follows:

[0036] Preparation mode: Before putting on the rescue vest, the worker should check the expiration date and integrity, and choose the appropriate size to wear.

[0037] Operating method: Depending on the external environment, without damaging the outer layer material of the vest compartment, external force is used to break the isolation membrane between the first reaction chamber 2 and the second reaction chamber 3 inside the compartment, generating a chemical reaction that provides heat generation and insulation, as well as gas generation and levitation. The generated oxygen can also be utilized. The compartment's heat generation can save heat, extend the functional time, and buy more opportunities for rescue.

[0038] Routine Maintenance: Although this rescue vest is made of waterproof material, it still needs to be stored in a dry and well-ventilated environment to prevent moisture from accidentally causing chemical reactions within the vest's compartments. The chemical reactions within the vest are irreversible, therefore all functions are for single use. Although the chemical reactions will not produce harmful substances, they must be collected and disposed of properly after use. Regularly check the production date to avoid functional malfunctions due to expired chemicals.

However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0040] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0041] Furthermore, the various implementation methods disclosed in this solution can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content invented by this disclosure.
