Hollow float

Abstract

The present invention relates to a hollow float, wherein when air is forcibly supplied through an inlet, air is supplied to an air bag through a check valve installed within the inlet, causing the air bag to expand to correspond to the internal space shape of the main body. Subsequently, a sealing unit is attached and fixed to a contact end to seal the inlet, thereby increasing the attachment area of ​​the sealing unit attached to the contact end, which has a relatively larger area compared to the inlet area, and improving the sealing force of the inlet of the main body. According to the present invention, the contact surface area is formed relatively wider than the area of ​​the injection port, thereby increasing the contact surface area to which the sealing unit is attached. The adhesion force between the sealing unit and the contact surface becomes robust in proportion to the adhesion area between the sealing unit and the contact surface. Due to the increased adhesion force of the sealing unit, there is no risk of the sealing unit detaching from the contact surface due to external impact. Furthermore, due to the robust adhesion force of the sealing unit, air inside the air bag is prevented from being released to the outside through the gap between the contact surface and the sealing unit. Accordingly, the hollow float can be used for a long period of time, thereby providing the advantage of improved product reliability.

Description

Technology Field

[0001] The present invention relates to a float, and more specifically, to a hollow float in which a sealing portion having a larger area than the injection port area is formed on the upper part of the main body, and when a sealing unit is attached to this sealing portion, the attachment area of ​​the sealing portion to which the sealing unit is attached is increased, thereby improving the sealing force of the injection port of the main body. Background Technology

[0002] Generally, floats are installed to float on the sea surface by means of buoyancy and are used to serve both a fixing function for installing various fishing gear, such as nets, in the seawater and a marking function to easily identify the location where the gear is installed.

[0003] Here, the floats currently widely used for aquaculture and fisheries are mainly foamed floats made by foaming and molding styrofoam and hollow floats made of plastic material, and recently, tube-type floats that are floated on the sea surface by inflating them with air injected into the tube are being used.

[0004] Here, while the foamed float made of the styrofoam material has the advantages of being inexpensive to manufacture and lightweight, making it easy to transport, it is easily corroded when exposed to seawater (saltwater) or sunlight for a long time, and as it absorbs a large amount of seawater, its buoyancy weakens, requiring frequent replacement.

[0005] In particular, if styrofoam is damaged by external impact or aging while floating on the surface of the sea, the debris covers the sea surface, damaging the marine aesthetics and causing seawater pollution, as well as causing secondary problems if fish consume it.

[0006] Meanwhile, the hollow float made of plastic material, which is used in conjunction with the foamed float made of styrofoam mentioned above, can be molded into various shapes and has the advantage of a longer lifespan compared to the foamed float made of styrofoam.

[0007] However, the above-mentioned hollow buoy must have a stable sealed state in the hollow buoyancy space formed inside to have buoyancy for floating on the sea surface, and if the sealed state of the hollow buoyancy space is damaged during transportation or use, water may enter the hollow buoyancy space, causing a problem of losing the buoyancy function.

[0008] Patent Document 1 describes a conventional hollow float, and with reference thereto, it comprises a main body part having a buoyancy space formed inside, a nozzle receiving space formed by being recessed at the top, an injection port formed on the bottom surface of the nozzle receiving space, and a sealing edge formed on the upper edge of the nozzle receiving space, an air injection unit coupled to the injection port of the main body part with its upper end exposed to the nozzle receiving space, and a ring part that is fixed in close contact with the sealing edge to seal the nozzle receiving space.

[0009] Here, the width of the nozzle receiving space is formed to be relatively wider than the width of the injection port, allowing the air supply device connected to the top of the air injection unit to enter the nozzle receiving space.

[0010] That is, by introducing the air supply device into the nozzle receiving space and connecting it to the top of the air injection unit, and then forcibly injecting air through the check valve section, the air passing through the check valve section is supplied to the air injection unit, causing the bottom of the air injection unit to expand within the buoyancy space of the main body, and subsequently, the air supply device is detached from the nozzle receiving space.

[0011] Then, attach a cap to the top of the air injection unit to seal the top of the air injection unit, and then attach and fix the sealing unit to the sealing end to seal the nozzle receiving space.

[0012] However, the above-described patent document 1 has a problem in that the width of the nozzle receiving space is formed to be relatively wider than the width of the injection port, and the width of the contact portion to which the sealing unit is attached is drastically reduced, and the sealing unit can easily detach from the contact portion due to external impact due to the reduction in the attachment area of ​​the sealing unit, and when the air pressure in the nozzle receiving space increases, pressure is applied to the sealing unit, and there is a risk that the sealing unit with a reduced attachment area may detach from the contact portion, and there is a risk that air inside the air injection unit may leak through the gap between the nozzle receiving space from which the sealing unit has detached due to external factors or the sealing unit with reduced adhesion and the contact portion, and consequently, the buoyancy function of the main body is lost, and the reliability of the product is reduced.

[0014] The present invention aims to solve the problems described above. The objective of the present invention is to provide a hollow float with improved sealing power for the inlet of the main body, comprising a main body having an inlet formed at the top and a sealing section formed on the upper edge of the inlet with an area larger than the inlet area, a check valve fixedly installed inside the inlet, an air bag provided in the internal space of the main body and connected to the lower end of the check valve, and a sealing unit provided on the upper surface of the sealing section to seal the inlet. When air is forcibly supplied through the inlet, air is supplied to the air bag through the check valve installed inside the inlet, causing the air bag to expand to correspond to the shape of the internal space of the main body. Subsequently, the sealing unit is attached and fixed to the sealing section to seal the inlet, thereby increasing the attachment area of ​​the sealing unit attached to the sealing section, which has an area relatively larger than the inlet area. means of solving the problem

[0015] To achieve the objective of the present invention as described above, the hollow float according to the present invention is characterized by comprising: a main body portion having a hollow shape, having an injection port formed through the upper end to communicate with an internal space, and a sealing portion formed on the upper edge of the injection port having an area relatively larger than the area of ​​the injection port; a check valve fixedly installed within the injection port of the main body portion to allow air to be drawn into the internal space of the main body portion, while blocking the discharge of air from the internal space of the main body portion to the outside of the main body portion through the injection port; an air bag provided in the internal space of the main body portion and connected to the lower end of the check valve to receive air drawn in through the check valve and expand to correspond to the shape of the internal space of the main body portion; and a sealing unit formed in proportion to the area of ​​the sealing portion of the main body portion, attached and fixed to the upper surface of the sealing portion, and having a loop portion formed to allow a rope or a loop to be hung on the upper surface to seal the injection port.

[0016] In the hollow float according to the present invention, the main body is characterized by further forming a valve coupling part that extends downward from the rim of the injection port so as to be in communication with the injection port at the inner upper end, and allows the check valve to be inserted and coupled therein, thereby fixing the upper end of the check valve so as to be positioned in alignment with the upper end of the injection port.

[0017] In the hollow float according to the present invention, the check valve is further characterized by including a cap that allows the upper end to be fastened in a spiral manner to seal the upper end of the check valve.

Effects of the invention

[0020] According to the present invention, the contact surface area is formed relatively wider than the area of ​​the injection port, thereby increasing the contact surface area to which the sealing unit is attached.

Due to the increased adhesion force of the sealing unit, there is no risk of the sealing unit detaching from the contact surface due to external impact. Furthermore, due to the robust adhesion force of the sealing unit, air inside the air bag is prevented from being released to the outside through the gap between the contact surface and the sealing unit. Accordingly, the hollow float can be used for a long period of time, thereby providing the advantage of improved product reliability. Brief explanation of the drawing

[0022] Hereinafter, embodiments of the present invention will be described in more detail with reference to the attached drawings.

[0023] The main body (100) has a hollow shape and forms an injection port (101) formed through the top so as to communicate with the internal space, and forms a contact portion (102) on the upper edge of the injection port (101) having a relatively larger area compared to the area of ​​the injection port (101).

[0024] It is preferable that the main body (100) be formed of a plastic material and float on the sea surface.

[0025] The above main body (100) is buoyant by the air bag (300) that is expanded and formed in the internal space, and is floated on the sea surface.

[0026] The area of ​​the above-mentioned contact portion (102) is formed to be at least twice as large as the above-mentioned injection port (101) so that the above-mentioned sealing unit (400) can be attached.

[0027] The above main body (100) is formed to extend downward from the rim of the injection port (101) so as to be in communication with the injection port (101) at the inner upper side, and further forms a valve coupling part (103) that allows the check valve (200) to be inserted and coupled therein, thereby fixing the upper side of the check valve (200) so that it is positioned in alignment with the upper side of the injection port (101).

[0028] The valve coupling part (103) allows the check valve (200) and the air bag (300) to be inserted and coupled, thereby securing the check valve (200) and the air bag (300).

[0029] The above valve coupling part (103) is preferably formed in a cylindrical shape and communicates with the injection port (101).

[0030] The above main body (100) further includes a sealing part (104) that is fused along the outer edge of the sealing unit (400) and the contact end (102) to seal the gap between the contact end (102) and the outer edge of the sealing unit (400).

[0031] It is preferable that the sealing portion (104) be formed with silicone or a heat-sealable film to seal the gap between the contact portion (102) and the sealing unit (400).

[0032] A check valve (200) is fixedly installed within the inlet (101) of the main body (100) to allow air to be drawn into the internal space of the main body (100), while blocking the air in the internal space of the main body (100) from being discharged to the outside of the main body (100) through the inlet (101).

[0033] The check valve (200) allows air to pass through so that air introduced through the inlet (101) is supplied toward the air bag (300).

[0034] The check valve (200) blocks the air inside the air bag (300) from being released toward the inlet (101), thereby preventing air leakage inside the air bag (300).

[0035] It is preferable that the check valve (200) be coupled within the valve coupling part (103) such that its upper end is positioned at the same height as the upper end of the injection port (101).

[0036] The above check valve (200) further includes a cap (201) that seals the top of the check valve (200) by allowing it to be fastened in a spiral manner at the top.

[0037] The cap (201) prevents air inside the air bag (300) from leaking towards the inlet (101) through the top of the check valve (200).

[0038] An air bag (300) is provided in the internal space of the main body (100) and connected to the bottom of the check valve (200), so that it receives air supplied through the check valve (200) and expands to correspond to the shape of the internal space of the main body (100).

[0039] It is preferable that the air bag (300) enters the valve coupling part (103) and is fastened to the bottom of the check valve (200) in a spiral manner.

[0040] The above air pocket (300) is preferably formed of a rubber or silicone material that contracts and expands.

[0041] The above air bag (300) is supplied with air and expanded as it is molded, thereby forming buoyancy in the main body (100).

[0042] The sealing unit (400) is formed in proportion to the area of ​​the contact portion (102) of the main body (100), is attached and fixed to the upper surface of the contact portion (102), and forms a loop portion (401) that allows a rope or loop to be hung on the upper surface, thereby sealing the injection port (101).

[0043] It is preferable that the sealing unit (400) has an area at least twice the size of the injection port (101) attached and fixed to the contact portion (102).

[0044] It is preferable that the sealing unit (400) be formed of the same plastic material as the main body (100) and attached to the upper surface of the contact portion (102) by a heat fusion method.

[0045] The sealing unit (400) is sealed off from the contact portion (102) by the sealing portion (104) formed along the outer surface of the contact portion (102).

[0046] The above-mentioned loop portion (401) has a loop hole (401a) formed therein to allow a rope or loop to be attached.

[0048] The hollow float according to the present invention, configured as described above, is used as follows.

[0049] In the following, the check valve (200) and the air bag (300) are described as being integrally connected to the injection port (101) of the valve coupling part (103) during the process of producing the main body part (100).

[0050] First, an air supply device (not shown) is connected to the inlet (101) of the main body (100) so that air is forcibly supplied to the inlet (101), and then air is forcibly supplied to the air bag (300) through the check valve (200).

[0051] At this time, the upper part of the check valve (200) is positioned in alignment with the upper part of the inlet (101), so that when air is supplied through the inlet (101), the air is immediately supplied into the air bag (300) through the check valve (200).

[0052] Here, the check valve (200) is a one-way valve that guides air to be injected into the air bag (300), while primarily blocking the air inside the air bag (300) from leaking out of the main body (100) through the inlet (101).

[0053] And, the air bag (300) is forcibly injected with air and expands to correspond to the shape of the internal space of the main body (100), thereby forming buoyancy on the main body (100) within the internal space of the main body (100).

[0054] Afterwards, a cap (201) is provided on the top of the check valve (200), and the cap (201) is fastened and fixed to the check valve (200) in a spiral manner to secondarily seal the top of the check valve (200), thereby blocking the air inside the air bag (300) from leaking out through the check valve (200).

[0055] Next, a sealing unit (400) is provided on the upper part of the main body (100), and the sealing unit (400) is attached to the contact end (102) in a state where it is in close contact with the contact end (102).

[0056] At this time, the sealing unit (400) is attached to the contact portion (102) by a heat fusion method to seal the injection port (101).

[0057] That is, the sealing unit (400) is brought into contact with the contact end (102), and heat is applied to the sealing unit (400) and the contact end (102) in that state so that the sealing unit (400) is heat-fused to the contact end (102), thereby sealing the injection port (101) by the sealing unit (400).

[0058] Here, the area of ​​the contact portion (102) is formed to be relatively larger than the area of ​​the injection port (101), and accordingly, the area of ​​the sealing unit (400) heat-fused to the contact portion (102) is increased.

[0059] And, the adhesion force between the sealing unit (400) and the contact member (102) is increased in proportion to the attachment area of ​​the sealing unit (400) attached to the contact member (102), thereby increasing the sealing force between the sealing unit (400) and the contact member (102).

[0060] Afterwards, a sealing portion (104) is attached between the contact portion (102) and the outer surface of the sealing unit (400) to seal the gap between the sealing unit (400) and the contact portion (102) for the third time.

[0061] At this time, the sealing portion (104) is formed from either silicone or a heat-fusion film, and seals the gap between the contact portion (102) and the sealing unit (400) by a heat-fusion method.

[0062] Then, the air inside the air bag (300) is first blocked by the check valve (200), then secondarily blocked by the cap (201), and subsequently thirdly blocked by the sealing unit (400), so that leakage to the outside of the main body (100) is prevented.

[0063] Next, when a rope is passed through the loop hole (401a) of the loop part (401) and the float is thrown onto the surface of the sea, the main body part (100), which has buoyancy formed by the air bag (300), floats on the surface of the sea, thereby fixing the net or fishing gear to a designated location in the seawater or marking the location where the fishing gear is installed in a way that makes it identifiable.

[0064] In the above description, the float was exemplified as being used for fixing fishing nets and gear and identifying the location of the gear; however, depending on the purpose of use, the float may float on the sea surface and perform other functions.

[0065] As described above, the structure in which a sealing unit (400) is attached to a sealing unit (102) by forming a sealing unit (102) with a relatively larger area compared to the area of ​​the injection port (101) is such that the sealing unit (400) is formed with a relatively larger area compared to the area of ​​the injection port (101), thereby increasing the sealing unit (400) attachment area, and the adhesion force between the sealing unit (400) and the sealing unit (102) becomes stronger in proportion to the attachment area of ​​the sealing unit (400) and the sealing unit (102), and there is no risk of the sealing unit (400) being detached from the sealing unit (400) due to external impact due to the increased adhesion force of the sealing unit (400).

[0066] The hollow float according to the present invention described above is not limited to the embodiments described above, and its technical spirit extends to the scope in which any person with ordinary knowledge in the field to which the present invention belongs can implement it by making various modifications without departing from the gist of the present invention as claimed in the following claims.
