Description

Buoy {FLOATING DEVICE}

The present invention relates to a float, and more particularly, to a float installed to support a water structure or to support a water structure.

Floating structures mean facilities that can be floated on the surface of the water, such as various farms, floating houses, and pedestals, depending on the purpose of use. Has been installed.

It is true that a typical water structure for water structures having such a purpose of use is made of Schiropul material with a low specific gravity, and thus has a relatively low production cost and a good support ability for the water structure. However, in view of the fact that such a float for the water structure is made of a styropool material having a material property that is vulnerable to the impact and load or frictional contact applied from the outside, it is high in the state of being bound to the water structure Due to the large impact caused by the waves or the frictional contact that occurs in the process of binding the rope to the water structure, the spool pulley is easily crushed or broken, which shortens the service life and causes the broken spool pieces to float on the surface of the water. It is accompanied by problems such as damaging the environment and polluting water quality.

In order to solve the above problems, the Korean Utility Model Publication No. 1995-511 (published on May 19, 1995), as shown in Fig. 1a and 1b, "Synthetic resin to have an internal charging chamber (4) In forming the spherical part spherical body 1 of material and having the fastening rings 2 and 3 integrally on both sides thereof, the inside of the fastening ring 2 of one side communicates with the charging chamber 4 in a space. Formed by (5), a culture farming mouth ", which is characterized in that the foaming injection of the styropool through the inlet (6) of one side has been announced as a first application. The fish farming spout foam-fills the styropool in the spherical spherical body 1, and the spherical spherical body 1 covers the spool pool in which the spherical spherical body is foam-injected inside, so that impact, load, frictional contact, etc. are applied from the outside. It is true that it has the advantage of preventing the squirrel from being damaged, thereby extending its service life, preventing the squirrel pieces from floating on the surface, damaging the environment and contaminating the water quality.

However, the spherical portion spherical body (1) in such a conventional aquaculture spherical spheres seep into the interior through damaged parts that are punctured by contact with naturally damaged or sharp foreign substances while repeating expansion and contraction in response to external temperature changes. Since the phenomenon is gradually submerged by water, there was a problem that loses the support capacity for the water structure.

The present invention has been made to solve the above problems, an object of the present invention is to provide a float that can be formed by thickening the float to prevent the float from being easily broken by an external collision or the like, and to prevent the buoyancy decrease due to immersion.

According to the present invention for achieving the above object is a first body member formed in the inlet groove on one side, and the first body member is joined to form a predetermined internal space therein with the first body member A main body including a second body member is provided, and the first and second body members are formed to be joined by heat fusion.

Filled into the inner space of the main body, further comprising a foam for blocking the inflow of water into the main body, wherein the first and second body members are injection molded into foamed plastic, the foamed plastic resin UV In order to prevent the aging caused by the UV stabilizer is preferably formed by addition.

The first and second body members may include first and second partition plates protruding from the inner circumferential surface to be joined to each other so as to form a partitioned space in which the foam is not filled. The first and second body members may include guide protrusions protruding along the joint surface of the first body member to guide the coupling positions on the joint surfaces to be joined to each other and to expand the area of the joint surfaces. A guide groove formed to allow the guide protrusion to be inserted into the bonding surface of the second body member may be formed.

The ball according to the present invention is formed to a thickness sufficient to improve the impact resistance to external impact and has the advantage of preventing water from penetrating into the buoyancy is lowered.

Hereinafter, with reference to the accompanying drawings will be described in more detail the accessory and the manufacturing method according to the present invention.

2 and 3 illustrate a preferred embodiment of the float 100 according to the present invention, referring to the drawing, the float 100 according to the present invention is a main body 110, the interior of the main body 110 It includes the baroque provided in.

The main body 110 has a cylindrical shape and is formed to have an inner space 111 in which the foam 130 is filled, and an injection hole 112 for filling the foam 130 is provided at one side thereof. In addition, the liquid foam 130 is injected through the injection hole 112 to be foam molded. And the injection hole 112 is to be closed through the cover member 113.

The main body 110 is formed by coupling the first and second body members 121 and 122 to each other.

The first and second body members 121 and 122 are formed through injection molding, respectively, and have a semi-cylindrical shape, and the inlet grooves 123 are introduced into the joining surfaces to be joined to each other, thereby providing the first and second bodies. When the members 121 and 122 are coupled to each other, an inner space 111 in which the foam 130 may be filled is formed by the inlet groove 123.

In addition, a guide protrusion 124 and a guide groove 125 extending along a circumference are formed at the joint portions of the first and second body members 121 and 122, respectively, so that the first and second body members 121 and 122 are mutually connected. When the guide protrusion 124 is inserted into the guide groove 125 can be easily fitted to the bonding position when combined.

In addition, the first and second body members 121 and 122 are injection molded with foamed plastic, and are formed to have a thickness of 5% or more of the diameter of the main body 110. In addition, the first and second body members 121 and 122, which are injected by adding an ultraviolet stabilizer to the molten resin during injection, are preferably minimized by aging by ultraviolet rays, thereby degrading the functionality.

As described above, the main body 110 according to the present invention is formed by bonding the first and second body members 121 and 122 formed by injection molding to each other, that is, by a method of manufacturing a conventional float 100, that is, a blow molding method. The shape of the main body 110 may be variously compared with the sub-ball 100, and the thickness of the main body 110 may be sufficiently thick to prevent the life of the sub-ball 100 from shortening. In addition, injection molding using the foamed plastic prevents the buoyancy from being lowered despite the increase in the thickness of the main body 110.

In the present embodiment, the main body 110 is generally cylindrical and formed in a shape in which a ring groove 114 extending in the circumferential direction is formed at the center of the outer circumferential surface thereof and is drawn inwardly, but the main body 110 is varied according to the purpose of use. It may be formed in the form.

The first and second body members 121 and 122 and the cover member 113 blocking the injection hole 112 may be bonded to each other through heat fusion.

The foam 130 is filled in the internal space of the main body 110 to block water from flowing into the main body 110.

When the first and second body members 121 and 122 are fused to each other to form the inner space 111, the liquid foamed resin is injected into the inner space 111 through the injection hole 112 formed at one side thereof.

The foam 130 is preferably foamed polystyrene, which is a foam resin that is commonly used, the foam 130 filled in the filling space is cured to fill the inner space 111, the body 110 in use Even if one side is damaged, water does not flow into the main body 110, so that even if a part of the main body 110 is damaged, it can be prevented from sinking.

In the present embodiment, the foam 130 is filled in the interior of the main body 110, but the injection hole communicates with the internal space when the first and second body members 121 and 122 are omitted by omitting the foam 130. The internal space of the main body 110 may be sealed so that the internal space of the main body 110 is not formed.

4, another embodiment of the float 100 is shown.

The first and second body members 121 and 122 may be thermally fused to each other to form one main body 110.

However, the first and second body members 121 and 122 of the present exemplary embodiment have first and second partition plates 126 and 127 that extend from the inner circumferential surface and are joined to each other when the first and second body members 121 and 122 are coupled to each other. That is, the two first partition plates 126 formed on the first body member 121 are joined to each other by the second partition plates 127 formed on the second body member 122, respectively. To form a space.

Therefore, in the main body 110 of the present embodiment, when the first and second body members 121 and 122 are coupled to each other, the inner space 111 is divided into three parts. Injection holes for filling the foam 130 are formed at the upper and lower ends of the main body 110, and each injection hole is closed by the cover member 113.

The volume of the partition space partitioned by the first and second partition plates 126 and 127 is formed such that the total specific gravity of the main body 110 does not become lower than the specific gravity of the water even when water is introduced and filled therein.

By providing a predetermined partition space inside the main body 110, it is possible to prevent the filling amount of the foam 130 filled in the main body 110 from being excessively large.

5 to 8 illustrate a method of manufacturing the float 100 according to the present invention.

First, referring to FIG. 8, the manufacturing method of the float 100 according to the present invention may include an injection step of injection molding the first and second body members 121 and 122, and mutually open the first and second body members 121 and 122. The heat fusion step of fusion to form the main body 110, the filling step of the foam 130 to fill the foam 130 into the interior of the main body 110, and curing the filled foam 130 and the cover member ( 113) to combine the finishing step to complete the production.

The injection step is injection molding the first and second body members 121 and 122 as shown in FIG. 5, and the first and second body members 121 and 122 using the foamed plastic resin melted in the injection mold 140. ) Are injection molded.

Since the injection molding of the first and second body members 121 and 122 in the separated state, respectively, as described above, the thickness of the body 110 is thicker than that of the float 100 formed through the conventional blow molding method. It is possible to shape the thickness at each part uniformly, and to manufacture various shapes of the product.

The heat fusion step is for bonding the first and second body members 121 and 122 formed through injection to each other, and as shown in FIG. 6, the first and second body members 121 and 122 through the heater 150. The guide protrusions 124 and the guide grooves 125 of the respective heat and then heat-sealed.

The main body 110 formed by fusion of the first and second body members 121 and 122 is in a state in which the internal space 111 is exposed to the outside through one injection hole 112, and the remaining part is sealed by heat fusion. It is.

Filling the foam 130 is a step of filling the foam 130 into the interior through the inlet 112 as shown in Figure 7, filling the foam 130 in the molten state and then curing the foam 130 Let's do it. Since the inner space is filled by the foam 130, even if a part of the main body 110 is damaged due to external impact or aging, water is introduced into the main body 110 to prevent the float 100 from sinking. Can be.

In the finishing step, the injection hole 112 is closed with the cover member 113 to close the inner space 111, and finish the production by finishing.

As described above, the buoy 100 formed according to the present invention is formed by heat-sealing the injection molded main body 110 as described above, so that the thickness of the main body 110 can be thickened to increase the strength, and the main body because the foamed resin is injected. 110 it is possible to increase the buoyancy of itself. In addition, by including the UV stabilizer when molding the body 110 can minimize the speed at which the buoy 100 is installed on the shore or river aging by ultraviolet rays, seawater or river water through the foam 130 is filled therein By the inflow of the buoy 100 can be prevented from sinking.
