Description

Technical Field

[0001] The present invention relates to a floating body at sea, and more particularly, to a floating body in which a lid member is disposed outside at least one leg, and by contacting the lid member, seawater is guided to flow outside the leg, thereby suppressing the flow of seawater between one leg and another leg, reducing the impedance of seawater, and smoothly moving at sea. Background Art

[0002] Recently, due to the serious environmental pollution caused by the use of fossil fuels, people have gradually paid attention to green renewable energy.

[0003] Green renewable energy is not only clean and inexhaustible, but also has the advantage of being able to be regenerated without pollution, so its scope of application is gradually expanding.

[0004] And, as a kind of green renewable energy, there is wind energy using a wind turbine.

[0005] A turbine is installed on a tower vertically connected to the wind turbine, and the turbine rotates by the wind and generates electricity.

[0006] However, since the volume of the turbine forming the wind turbine is large, a large installation space is required, and there is a problem of restriction on the installation site.

[0007] And, when the turbine of the wind turbine rotates, a large amount of noise is generated, so there is a problem of causing complaints from surrounding residents.

[0008] To solve the above problems, recently, offshore wind turbines have been used.

[0009] Offshore wind turbines are installed in the sea far from houses and the like, so it is easy to secure space, and there is no public complaint caused by noise.

[0010] At this time, if an offshore wind turbine is directly fixedly installed at sea, not only does the amount of underwater work increase, but also the need for materials such as ground piles increases, so there is a problem of increased cost burden.

[0011] For the above reasons, recently, there have been many cases where an offshore wind turbine is installed on a "floating body at sea" disclosed in Korean Patent Publication No. 10-2023-0061118 and the like.

[0012] If an offshore wind turbine is installed using a floating body at sea, not only can the amount of underwater work be reduced, but also the need for materials such as ground piles can be reduced, thereby reducing the cost burden.

[0013] However, a general floating body at sea applicable to an offshore floating wind system and the like has a problem of being difficult to tow.

[0014] That is, a conventional offshore floating body for applications such as an offshore floating wind power system has a plurality of legs with a separated configuration. During the towing process, seawater flows between one leg and another, thereby causing a large impedance. Therefore, during offshore towing, the power and fuel efficiency of the tugboat are reduced, and there are problems such as an increase in the cost for towing.

[0015] For the above reasons, attempts have been made in this field to develop an offshore floating body that can reduce the impedance caused by seawater and can be easily towed. However, satisfactory results have not been obtained so far.

[0019] (I) Technical Problems to be Solved

[0020] The present invention is proposed to solve the above-mentioned conventional problems, and its object is to provide an offshore floating body that can suppress the seawater flow between one leg and another during towing, thereby reducing the impedance caused by seawater and facilitating movement at sea.

[0021] (II) Technical Solutions

[0022] To achieve the above object, the present invention provides an easily towable offshore floating body, comprising: a plurality of legs arranged at intervals from each other; and connecting rods respectively connected between one and another of the legs, and further comprising: a lid member that locally wraps the outer surface of at least one of the legs, so that during offshore towing, the seawater flow is guided to the outside of the legs by contact with the lid member, thereby suppressing the seawater flow between one leg and another and reducing the impedance of seawater.

[0023] (III) Advantageous Effects

[0024] The easily towable offshore floating body of the present invention not only includes legs and connecting rods, but also includes a lid member arranged to locally wrap the outer surface of at least one leg. Thus, during the offshore towing process, by contact with the lid member, the seawater flow is guided to the outside of the legs, suppressing the seawater flow between one leg and another, reducing the impedance caused by seawater, and thus facilitating towing at sea.

[0025] Moreover, for the easily towable marine floating body of the present invention, the lid member is fixed to the leg through the engagement with the engaging member. When the engagement with the engaging member is released, the lid member can be separated from the leg and the separated lid member can be applied to other marine floating bodies, thereby improving the utilization rate of the lid member.

[0031] Hereinafter, the present invention will be described in detail with reference to the drawings.

[0032] As Figure 1 shown, the easily towable marine floating body A of the present invention includes: legs 10 and connecting rods 20.

[0033] A plurality of legs 10 of the present invention are formed and are arranged at intervals from each other.

[0034] Thus, an object to be supported (not shown in the drawings) arranged on the upper part of the legs 10 is supported by each leg 10.

[0035] Here, the legs 10 have buoyancy, so that the object to be supported supported by the legs 10 can float on the sea.

[0036] Here, the number and arrangement form of the legs 10 are not limited.

[0037] For example, three legs 10 can be arranged in a triangular form, or four legs can be arranged in a quadrilateral form, and an additional arrangement can be made at the center of the triangular form formed by three or at the center of the quadrilateral form formed by four.

[0038] Moreover, the leg 10 includes a protrusion 11 arranged at at least one position on the outer surface.

[0039] Thus, the lid member 30 described below is combined with the protrusion 11, and the lid member 30 is separated from the outer surface of the leg 10.

[0040] Here, the protrusion 11 is formed with a bolt coupling member (not shown in the drawings), and the coupling member 31 described below, that is, the bolt is coupled to the bolt coupling member, so that the lid member 30 can be combined with the protrusion 11.

[0041] The connecting rod 20 of the present invention is respectively connected between one leg 10 and another leg 10.

[0042] Thus, a plurality of legs 10 are connected by the connecting rod 20.

[0043] Here, a plurality of connecting rods 20 are respectively provided between one leg 10 and another leg 10.

[0044] Thus, one leg 10 and another leg 10 are stably connected by a plurality of connecting rods 20.

[0045] The function of the above-mentioned connecting rod 20 is only to connect one leg 10 and another leg 10, and does not have a special function. Therefore, the detailed description of the connecting rod 20 is omitted.

[0046] Moreover, the easily towable marine floating body A of the present invention further includes a lid member 30.

[0047] The lid member 30 of the present invention partially wraps the outer surface of at least one leg 10.

[0048] Thus, when towing the easily towable marine floating body A at sea, the seawater contacts the lid member 30, and the seawater can be guided to flow outside the leg 10.

[0049] Here, the lid member 30 partially wraps the outer surface of at least one leg 10 and wraps the section between the corresponding leg 10 and another leg 10 separated therefrom. Thus, the seawater flow can be guided to the outside of the leg 10 in the section between the corresponding leg 10 and another leg 10 separated therefrom.

[0050] Moreover, the lid member 30 is formed to be gradually sharp from the rear to the front, so that the seawater contacts the front of the lid member 30, and the seawater flow is dispersed to the outside of the lid and travels backward. Thus, the impedance caused by the seawater can be suppressed.

[0051] Here, a curved surface with a predetermined curvature is formed at the foremost part of the lid member 30. Thus, the seawater contacts the foremost part of the curved surface of the lid member 30, and the occurrence of seawater impedance can be further suppressed.

[0052] Moreover, the lid member 30 is fixed to the leg 10 by being combined with the coupling member 31.

[0053] Therefore, when the engaging member 31 is disengaged, the leg 10 can be separated from the lid member 30 and used for other marine floating bodies.

[0054] Here, the engaging member 31 can be a bolt. However, the bolt is only an example of the engaging member 31, and other members such as a snap hook can be used as the engaging member 31 in addition to the bolt.

[0055] Moreover, the lid member 30 includes a snap hook 32 disposed at at least one position on the outer surface.

[0056] By connecting the towing rope 110 connected from the tugboat 100 to the snap hook 32, the towing rope 110 can be simply connected.

[0057] Furthermore, the entire lid member 30 can be made of steel, but is not limited thereto.

[0058] That is, only the outer frame of the lid member 30 is made of steel, and the inner part of the frame can be made of plastic, so that buoyancy can be sufficiently ensured.

[0059] Moreover, the lid member 30 can be generally triangular in shape, but is not limited thereto.

[0060] That is, the lid member 30 wraps at least one leg 10 and guides the flow of the fluid in a specific direction. That is, if impedance generation can be reduced, it can be formed in any common shape.

[0061] Next, the towing of the easily towable marine floating body A of the present invention will be described in detail.

[0062] The easily towable marine floating body A of the present invention includes legs 10 and connecting rods 20.

[0063] Accordingly, after connecting the towing rope 110 connected from the tugboat 100 to at least one of the legs 10 and the connecting rods 20 and pulling it, towing can be performed.

[0064] A plurality of legs 10 are provided in the present invention and are arranged at intervals from each other. Therefore, during towing, seawater flows between one leg 10 and another leg 10, so that a large impedance occurs, and there are problems such as reduction of the power and fuel efficiency of the tugboat.

[0065] However, the present invention further includes a lid member 30 that partially wraps the outer surface of at least one leg 10. As Figure 2 shown, when towing in a state where the lid member 30 is relative to the tugboat 100, as Figure 3As shown, the flow of seawater can be guided to the outside of the leg 10 by contact with the lid member 30. Thus, the flow of seawater between one leg 10 and another leg 10 can be suppressed, and the impedance caused by seawater can be reduced. As a result, it is easy to tow at sea.

[0066] Here, the lid member 30 partially wraps the outer surface of at least one leg 10, and wraps the interval between the corresponding leg 10 and another leg 10 separated therefrom. Thus, the inflow of seawater into the interval between the corresponding leg 10 and another leg 10 separated therefrom is suppressed by the lid member 30. Therefore, the flow of seawater between one leg 10 and another leg 10 can be further suppressed, and the impedance caused by seawater can be further reduced. As a result, it is easier to tow at sea.

[0067] In addition, the lid member 30 is formed to be gradually sharp from the rear to the front, so that the seawater contacts the front of the lid member 30, and the flow of seawater is dispersed to the outside and then travels backward. Therefore, the impedance caused by seawater can be further suppressed.

[0068] In addition, a curved surface with a predetermined curvature can be formed at the foremost part of the lid member 30, so that the seawater contacts the foremost part of the lid member 30 forming the curved surface. Thus, the impedance of seawater can be further suppressed.

[0069] In addition, the easily towable marine floating body A of the present invention can be simply connected to the towing rope 110.

[0070] That is, the lid member 30 of the present invention includes a hook-and-loop 32 disposed at at least one position on the outer surface, and the towing rope 110 connected from the tugboat 100 is connected to the hook-and-loop 32, so that the towing rope 110 can be simply connected.

[0071] In addition, the easily towable marine floating body A of the present invention can improve the utilization rate of the lid member 30.

[0072] That is, as Figure 4 shown, the lid member 30 of the present invention is fixed to the leg 10 by being combined with the combining member 31. When the combination with the combining member 31 is released, the lid member 30 can be separated from the leg 10, and the separated lid member 30 can be used for other marine floating bodies. Thus, the utilization rate of the lid member 30 can be improved.

[0073] In addition, the easily towable marine floating body A of the present invention facilitates the combination of the lid member 30.

[0074] That is, as Figure 5As shown, the leg 10 of the present invention includes a protrusion 11 provided at at least one position on the outer surface, and a bolt coupling member may be formed on the protrusion 11. By coupling the coupling member 31 that penetrates the lid member 30, that is, by coupling the front end of the bolt to the bolt coupling member formed on the protrusion 11 of the leg 10, the lid member 30 can be simply coupled.

[0075] The present invention described above is not limited to the above-described embodiments. Therefore, changes can be made without departing from the gist of the present invention claimed in the claims, and the above changes fall within the protection scope of the present invention defined in the claims.
