[0001] FLOATING BODY WITH VACUUM PREVENTING MOVEMENT DEVICE [0002]

The present invention relates to a float having a vacuum flow prevention device, and more particularly, to a float having a vacuum float prevention device, and more particularly to a flotation line installed on a coast of a lake or sea, And it is possible to minimize the fluctuation of the float due to waves, waviness, and blue waves without affecting the buoyancy or weight of the float at a normal time, thereby making it possible to anchor the vessel or to operate on the floating body for getting on and off the ship or barge The present invention relates to a float provided with a vacuum flow prevention device capable of securing the safety of the people who make the water flow, as well as improving the durability and the wave resistance of the water float.

The term "floating bridge" generally refers to a pier structure that is installed in a floating state on a water surface and can be freely moved up and down depending on the height of a water surface. To provide a route through which people or cargo can travel, and is usually used by connecting several floating bridges over the entire route (length).

In addition, the barge line refers to a non-powered ship carrying cargoes in ports, inland waters, lakes, rivers, canals, etc., or equipped with construction equipment for offshore operations, and carries large-scale construction materials and construction equipment by sea It refers to a ship manufactured in such a form that a large space is secured on the upper part of the ship to provide a working space at sea.

These barges are used to carry cargo between two points or to ship next to the main line to load or unload cargoes when large ships can not berth in the harbor, or to carry out coastal construction with various construction equipments, Most of them do not have the power for their own operation but are configured to be pulled by a tugboat or driven by a mop.

However, as described above, marine floats such as floating floats and barges float in the sea, and the vessel is severely rocked due to the high wave or storm caused by deterioration of the weather condition of the ocean when the lifting work of the weight is carried out or the marine work is performed It is not only very unstable but also has a problem in that safety accidents such as conduction of construction equipment and operator's fault are often occurred. Furthermore, if the arrangement of the weights loaded on the deck of the barge could not be arranged uniformly, it would lead to a rollover of the hull.

Accordingly, in the conventional technique disclosed in Korean Patent No. 10-1476104 entitled " Barge with Horizontal Holding Device and Its Control Method ", a technique for generating a swing suppressing moment in response to the swinging of the ship is disclosed.

However, in order to construct the inclination detecting unit 400 and the like, the conventional technique as described above is very complicated in the construction of the box 310 or the like for each corner of the barge 100, A high buoyancy force is required for lifting the barge, and various sensors are electronically measured. Therefore, maintenance and repair of such devices are required to be performed from time to time, so that economical efficiency and efficiency are deteriorated, If you do not play the role, you will not be able to recognize it easily, so there is a problem that the people who work on the water surface can be exposed to the dangerous situation.

FIG. 2 is a perspective view showing an example of the installation of a float with a vacuum flow prevention device according to an embodiment of the present invention, FIG. 3 is a perspective view of a float with a vacuum flow prevention device according to an embodiment of the present invention, Sectional view showing the operating state.

Referring to the drawings, a float having a vacuum flow prevention device according to an embodiment of the present invention includes a float 10 and a floating barrier 20.

The float (10) is a variety of flood structures such as floating floats and barges which can be installed on the coast of the lake or the sea. Such float (10) is irregular due to external factors such as wind and waves At this time, a plurality of the fluid skimmers 20 may be installed at positions where upward and downward flows are predicted along the side edges of the float 10, that is, the outer edges.

The fluid bag 20 is integrally connected to the side of the float 10 through a separate connecting means. At this time, the connecting means may be composed of various connecting devices such as a U-bolt, a clamp, and a bracket capable of stably fixing the floating damper 20 to the float 10. And is not particularly limited.

2, the floating body 20 has a cylindrical or rectangular shape having an inner space 21 in which a lower portion of the float 10 is opened through various connecting devices and an inner space 21 in which a predetermined amount of seawater can be filled is formed, Or in the form of a box or box.

The floating damper 20 is installed at an appropriate height on the side of the float 10 so that the internal space 21 is located at a position where the internal space 21 can be locked at a predetermined depth in the water, And may be disposed to a height enough to form an air space 21a in an appropriate space on the upper side of the internal space 21 in a state where most of the internal space 21 is locked.

In addition, the fluid guide passage (20) is formed with an air flow passage (22a) which is exposed to the air in the upper part so that only a small amount of air flows through the inner space (21).

At this time, the air flow path 22a may be formed as a small hole penetrating the upper end of the floating damper 20. However, it is preferable that the air flow path 22a has a hollow Shaped body 22. The tubular body 22 is formed in a narrow and long shape so that only a small amount of air can flow through the air flow path 22a, Is prevented from flowing into the air flow path 22a.

The air flow path 22a formed inside the tube 22 provides an internal passage through which air from the outside of the water surface can flow into the internal space 21. As a result, The buoyancy of the float 10 and the weight of the float 10 are not greatly affected when the float 20 is suspended on the water surface together with the float 10.

Meanwhile, the floating body 20 is configured to reduce the phenomenon that the side portion of the float 10 swings when the float 10 swings from the water surface by the wind, waves, Feature.

Referring to FIG. 3, when one side of the float 10 instantly rises from the water surface during the upward and downward flows, the floating body 20 rises along the float 10 The air layer 21a is brought into a low pressure state due to a pressure difference with the outside in the internal space 21 of the fluid dynamic bearing member 20 so that the internal space 20 is filled with seawater, The floating body 20 acts as a weight for reducing the swinging motion of the float 10.

That is, since the air flow path 22a is formed to be narrow and long so that only a small amount of the proper air flows, when the flow direction of the fluid 20 rapidly rises from the surface of the water, So that air can not be introduced into the internal space 21. At this time, the fluid skimmer 20 is raised on the water surface in a state in which the internal space 21 is filled with seawater by the atmospheric pressure acting on the water surface and the water pressure in the water.

In this way, when the fluid skimmer 20 is rapidly raised from the surface of the water, the temporary vacuum state of the air layer 21a can be maintained for a few seconds, The seawater in the internal space 21 is filled with the same height as the height of the water surface. In this state, since the floating damper 20 is already in a state of being stabilized in its swing motion The float 10 is floated in a stable state integrally with the float 10 without significantly affecting buoyancy of the float 10 and can effectively suppress shaking due to the instantaneous movement of the float 10 .

The tubular body 21 has an S-shape or a U-shaped siphon tube shape so as to slow the air inflow speed from the outside when the floating body 20 is lifted from the water surface And the inner passage of the tube 21 is preferably formed in a narrow and long shape so that a small amount of appropriate air can flow.

Also, in the float having the vacuum flow prevention device according to the embodiment of the present invention, the floating body 20 has a plate portion 23 protruding outward by a predetermined width along the lower end thereof do.

The plate portion 23 protrudes horizontally and horizontally in the form of a flange to extend along the periphery of the opening portion opened to the lower side of the floating damper 20, so that when the floating fluid 10 swings up and down, 20 to increase the resistance to water so as to apply a reaction force when the water is raised or lowered.

Accordingly, the fluid dynamic bearing member 20 has a weight for reducing the fluctuation of the float 10 at the time of swinging the float 10 through the organic coupling relationship of the components including the plate portion 23 It is possible to maximize the prevention of the flow of the float 10 by increasing the reaction force against the upward or downward movement.

In addition, the float with the vacuum flow prevention device according to an embodiment of the present invention may further include air supply adjusting means 30 for opening and closing the air into the internal space 21.

Referring to FIG. 5, the air supply adjusting means 30 may include a one-way check valve 32 installed at an upper end portion of the tube 22.

The one-way check valve 32 is configured to produce the same effect as the application of the orifice 31. That is, when the floating damper 20 rises from the water surface, the internal space 21 rises in a state filled with seawater so that the float 10 can act as a weight.

The unidirectional check valve 32 is installed at an upper end portion of the tube 22 so that when the floating damper 20 is suspended with the float 10 in a flat state on the water surface, When the fluid flow path 22a of the tubular body 22 is kept open and the floating fluid 20 is lifted from the water surface as the float 10 flows upward and downward, Is closed so that the air layer 21a of the internal space 21 is temporarily vacuumed by atmospheric pressure and water pressure acting on the water surface and at the same time the internal space 21 is filled with seawater, Thereby allowing the support 20 to rise.

6 and 7 are perspective views illustrating a modified example of the air supply adjusting means of the float having the vacuum flow prevention device according to the embodiment of the present invention.

6, the air supply adjusting means 30 may include a throttle valve 33. The throttle valve 33 may include a cover (not shown) for blocking the inlet of the air to the distal end of the tube 22 And a hinge shaft 33b for hinge-connecting one end of the lid 33a to the distal end of the tubular body 22 so that the lid 33a is rotated and opened and closed.

The throttle valve 33 configured as described above allows the throttle valve 33 to be closed when the air layer 21a of the internal space 21 is in a low pressure state as usual or when the fluid bag 20 is lifted from the water surface, A pressure is generated in the air flow hole 22a of the tubular body 22 when the hydraulic pressure acts on the internal space 21 due to the movement of the fluid dynamic bearing member 20, Can be opened.

7, the air supply adjusting means 30 may be formed of a buoyancy valve 34. The buoyancy valve 34 is connected to the air flow hole 22a at the upper end portion of the tube body 22, A spherical buoyancy ball 34c for closing the air flow hole 22a in a state of being seated on the bowl 34a and a buoyancy ball 34c And a guide 34b for restricting the linear motion by a predetermined height in the vertical direction.

The buoyancy valve 34 configured as described above closes the air flow hole 22a in a state in which the buoyancy ball 34c is seated on the inner circumferential surface of the bowl 34a and flows through the throttle valve 33 When the hydraulic pressure acts on the inner space 21 of the fluid bag 20 as the pressure is generated in the air bag 22a, the buoyancy ball 34c floats in the air, 22a can be opened.
