Dry ice packaging type anti-deformation float {Dry ice packaging type anti-deformation float}

The present invention relates to a dry ice packaging type deformation prevention device, and more specifically, by fixing the upper and lower hemispheres by heat fusion and supplying dry ice to the internal space to increase the air pressure by vaporization, so that the internal air pressure is higher than the external air pressure. This is about a dry anise-packaged deformation-prevention float that increases height and prevents shrinkage to maintain the shape of the float.

In general, fishing nets (nets) used for catching fish or cultivating fish in the sea are installed with a float attached to the upper side of the net so that it can be erected vertically at sea, and a weight for fishing net, which is a heavy body, attached to the lower side of the fishing net.

In this way, conventional floats use Styrofoam floats or plastic floats.

The Styrofoam float is cheaper than the plastic float, but has poor durability, and the plastic float is more durable than the Styrofoam float, but is expensive.

Moreover, all of the above-described conventional floats have a cylindrical shape, but their buoyancy is weak because they have a cylindrical shape that does not form a space inside, and because of this, a large number of floats have to be installed in fishing nets, which reduces workability and costs. There was also a problem of rising.

In addition, conventional floats are simply made of Styrofoam or plastic and are installed on fishing nets, but when installed on fishing nets to capture fish, there is a problem in that they do not have the function of emitting light or emitting light, so they are not effective in catching fish.

In general, expanded polystyrene (EPS: Expanded polystyrene), commonly referred to as Styrofoam, is widely used when installing various fishing gear in aquaculture farms.

However, in the case of the above-mentioned Styrofoam material, although it has the advantage of being able to be manufactured at a low price, it is weak in durability and breaks easily, and when exposed to seawater and sunlight for a certain period of time, it is damaged or decomposed and dispersed throughout the sea area along the ocean current, causing serious environmental pollution. And there is a problem of disturbing the ecosystem.

Meanwhile, Korea Registered Patent No. 10-0903073 (sealed float with improved structure for rational manufacturing) covers the outside of the Styrofoam float with a semi-cylindrical float cover to prevent corrosion and damage to the inner Styrofoam. Although it includes a cover, in the case of the above-described prior invention, there was a problem in that the cover had to be manufactured and assembled separately, and the environmental impact assessment (environmental impact assessment) was required due to the secondary problem of having to separate and dispose of it when disposing of it at the end of its lifespan. The environmental load due to Life Cycle Assessment (Life Cycle Assessment) is so large that its use is bound to be limited.

In addition, the above-mentioned father-son cover has the risk of being easily damaged by external shocks, such as waves or collisions with fishing boats. When the father-son cover is damaged, the Styrofoam inside is inevitably exposed, and the exposed Styrofoam is easily broken, so the father-son cover is damaged. This is undesirable because its function deteriorates and broken Styrofoam pieces float around, adversely affecting the marine ecosystem.

In addition, in the case of the above-mentioned prior invention, there was a problem in that barnacles, etc. could easily attach to the Styrofoam, so as its own weight increased, it sank into the water and could not perform the function of a buoyancy body.

Accordingly, recently, a method of manufacturing a float using foamed polypropylene, a durable and eco-friendly material, has been devised, and Korean Patent No. 10-1246931 (Foamed polypropylene float and its manufacturing method) uses a core for supplying steam. A method of manufacturing a float using expanded polypropylene, which is difficult to produce above a certain thickness, is disclosed by inserting and supplying steam to the inside of the float.

However, in the case of the above-mentioned prior invention, not only is the mold manufacturing and production process complicated in the process of manufacturing the rich material, but also a steam penetration hole is inevitably required inside the product so that the product thickness does not exceed 100MM for fusion and molding of the product. Due to the problem of installation, there are restrictions on realizing the shape of a typical float, and in order to maintain a certain buoyancy, the density of the product is excessively lowered, so it has a structure that is relatively easily damaged by external forces, so there are many problems in achieving the intended purpose as a buoyancy body.

In addition, if the thickness of the product exceeds a certain thickness, the steam used during molding is not distributed smoothly, resulting in poor internal fusion, which reduces the physical strength of the product and increases the possibility of absorption, thereby impeding its function as a rich product. There is a problem of easily losing .

[Document 1] Patent Registration No. 1801709 (registered on November 21, 2017) [Document 2] Patent Registration No. 1976978 (registered on May 2, 2019) [Document 3] Patent Publication No. 2019-0071923 (published on June 25, 2019) [Document 4] Patent Publication No. 2014-0120983 (published on October 15, 2014)

Therefore, the problem of the present invention, which was devised to solve these conventional shortcomings, is to supply dry ice to the internal space in the process of fusing the upper and lower hemispheres, which are made of a certain thickness by forming a space inside, to melt the opportunity. The purpose is to increase the atmospheric pressure.

Another problem solved by the present invention is to prevent shrinkage by increasing the internal air pressure of the float compared to the outside due to dry ice, so that it is not easily deformed by external impact.

The present invention includes an upper hemisphere with an upper ring formed above the center and an upper space formed inside to have a constant thickness, and a lower hemisphere formed at the lower center and a lower space formed inside to have a constant thickness. It includes, and consists of a father and son welded along the weld line where the upper hemisphere and the lower hemisphere meet;

Dry ice is supplied and packed in the upper and lower spaces, and the dry ice melts and vaporizes, thereby increasing the air pressure.

The dry ice of the present invention is vaporized and the atmospheric pressure increases to 5 to 10 Pascal (Pa), resulting in a difference in internal and external atmospheric pressure;

The dry ice should occupy 5 to 75% of the total cross-sectional area of the upper and lower spaces;

Putting the dry ice in a dry ice bag, supplying it to the upper space and the lower space and welding it along the weld line;

The dry ice bag is characterized in that the dry ice inside is vaporized and the air pressure increases to 5 to 10 Pascals (Pa), resulting in a difference in air pressure between the inside and the outside.

The present invention has the effect of supplying dry ice to the internal space during the process of fusing the upper and lower hemispheres, which are formed with a space of a certain thickness and are made of a certain thickness, by supplying dry ice to the internal space, thereby increasing the air pressure. is to provide.

In the present invention, the internal air pressure of the float is higher than that of the outside due to dry ice, preventing contraction of the float due to the difference in air pressure between the inside and outside, so that it is not easily deformed by external shock, which has the effect of stably providing buoyancy.
