Abstract

A throwable lifebuoy is disclosed, characterized by comprising: a cover formed in a spherical shape and coated with luminous paint to facilitate throwing to a drowning person; the cover being formed of a water-soluble material so as to melt quickly upon contact with moisture; the lifebuoy including a rope connected to the cover via a rope hook so that a rescuer can pull the thrown lifebuoy ; and the lifebuoy including, inside the lifebuoy, a life vest, a CO2 cartridge storing CO2 , a CO2 cylinder included inside the life vest and connected to the CO2 cartridge to allow CO2 to flow in, and a moisture-sensing inflator connected to the CO2 cartridge and the CO2 cylinder to detect moisture and inflate the CO2 cylinder.

Claims (5)

  1. In a throwable lifebuoy system comprising a lifebuoy equipped with a spherical or rugby ball-shaped outer cover for throwing to a drowning person, The above cover is made of a water-soluble material that dissolves upon contact with moisture, has a thickness of 5 mm or less, and dissolves within 5 seconds or less after contact with moisture to expose the life vest contained inside the lifebuoy, and The above life vest contains a CO₂ cartridge in which CO₂ is stored; A CO₂ cylinder connected to the above cartridge and capable of CO₂ inflow; and It includes a moisture-sensing inflator that detects moisture and expands the CO₂ cylinder, and A manual lever (151) that can be operated when the above moisture sensing inflator (150) is not in operation is further included, and The outer surface of the above cover is coated with luminous paint, and A rope is connected to the above cover through a rope hook so that a rescuer can retrieve the drowning person, and The length of the above rope is 25m or more and 30m or less, and The above lifebuoy is detachably installed on a mounting bracket, and The above mounting bracket includes a drive unit that controls the launch angle and launch strength of the above lifebuoy, and The above drive unit automatically launches the lifebuoy in the direction of the drowning person according to a signal from a distress alarm device or a control unit, and The above control unit calculates the initial launch velocity based on the location information of the drowning person, and A throwable lifebuoy system characterized by calculating the launch angle based on wind direction and distance information and controlling the mounting bracket.
  2. In paragraph 1, A throwable lifebuoy system characterized in that the material of the above-mentioned cover comprises at least one of polyvinyl alcohol (PVA), carboxymethylcellulose (CMC), or hydroxypropylmethylcellulose (HPMC).
  3. In paragraph 1, The above CO₂ cartridge and inflator are a throwable lifebuoy system that can be reused after recovery.

Description

Throwing Life Buoy The present invention relates to a throwable lifebuoy and a system thereof, and more specifically, to a lifebuoy and a system thereof that is small in volume and weight, has good throwability, and is recyclable. The matters described in this background technology section are written to enhance understanding of the background of the invention and may include matters that are not prior art already known to those skilled in the art to which this technology belongs. If you visit a harbor or coastal area, you can see round lifebuoys installed in various places. These lifebuoys are called lifebuoys and are rescue devices that are thrown toward a drowning victim to help them grab onto the buoy and float on the water. However, existing lifebuoys have the disadvantage of being bulky and heavy, making it difficult to throw them over long distances and limiting the range of rescue operations. To address this, there is a growing need for lifebuoys that are compact, lightweight, and easy to throw. Accordingly, the present invention was created to solve the aforementioned problems. The embodiments of this specification may be better understood by referring to the following description in conjunction with the attached drawings, in which similar reference numerals refer to identical or functionally similar elements. FIG. 1 is a drawing illustrating the shape of a throwable lifebuoy according to one embodiment of the present invention. FIG. 2 is a drawing illustrating the internal structure of a throwable lifebuoy according to one embodiment of the present invention. FIG. 3 is a drawing illustrating a throwable lifebuoy system according to one embodiment of the present invention. FIG. 4 is a drawing illustrating a throwable lifebuoy system including a control unit according to one embodiment of the present invention. The drawings referenced above are not necessarily drawn to scale and should be understood as presenting somewhat simplified representations of various preferred features illustrating the basic principles of the present disclosure. For example, specific design features of the present disclosure, including specific dimensions, orientations, positions, and shapes, will be partially determined by specific intended applications and usage environments. The terms used herein are for the purpose of describing specific embodiments only and are not intended to limit the disclosure. As used herein, singular forms are intended to also include plural forms unless explicitly otherwise indicated in the context. It will also be understood that the terms “comprising” and/or “comprising,” as used herein, specify the presence of the mentioned features, integers, steps, operations, components and/or components, but do not exclude the presence or addition of one or more of other features, integers, steps, operations, components, components and/or groups thereof. As used herein, the term “and/or” includes any one or all combinations of the associated items listed. Throughout the specification, when a part is described as being "connected" to another part, this includes not only cases where they are "directly connected," but also cases where they are "electrically connected" with other elements interposed between them. Furthermore, when a part is described as "including" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components; it should be understood that this does not preclude in advance the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. The present invention will be described in more detail below with reference to the description of the drawings and embodiments. FIG. 1 is a drawing showing the shape of a throwable lifebuoy according to one embodiment of the present invention, and FIG. 2 is a drawing showing the internal structure of a throwable lifebuoy according to one embodiment of the present invention. As can be seen by referring to FIGS. 1 and 2, a throwable lifebuoy (100) according to one embodiment of the present invention may be formed in a spherical shape to facilitate throwing to a drowning person. Overall, the volume and weight of the lifebuoy (100) are significantly reduced compared to conventional lifebuoys, and it is formed in a spherical shape that allows for a good grip for throwing. As one example, the cover (110) of the lifebuoy (100) may be shaped like a rugby ball. As another example, the cover (110) of the lifebuoy (100) may be formed in a spherical shape with a diameter of 20 cm. A luminous paint may be applied to the cover (110). As the luminous paint is applied, the lifebuoy (100) can be clearly seen by both the thrower and the drowning person even at night, and can be easily found. Thus, the rescue rate can be increased. As one example, the luminous paint may correspond to fluorescent paint or fluorescent spray. According
