The present subject matter in general relates to a structure and, particularly but not exclusively, to a farming structure for aquatic farming.
Aquatic farming of multicellular organisms for production of bio-mass, such as seaweeds, is known for a long time. Aquatic farming includes floating-type and submerged-type farming which are typically done using a farming structure on which multicellular organisms are supported and grown. In floating-type farming, the farming structure either floats on the water surface of a water-body or floats partially below the water surface. On the other hand, in submerged-type farming the farming structure is held immersed in the water-body. The farming structures are typically supported by buoys that provide suitable buoyancy to the floating structures, either for the purpose of floating-type farming or for the purpose of submerged-type farming. In addition, the farming structures, for the purpose of aquatic farming, are typically anchored to the base of the water-body to hold its position in the water-body.
This summary is provided to introduce concepts related to a farming structure for aquatic farming. This summary is neither intended to identify essential features of the claimed subject matter nor is it intended for use in determining or limiting the scope of the claimed subject matter.
In accordance with an embodiment of the present subject matter, a farming structure for aquatic farming comprises a plurality of longitudinal members and a plurality of flexible joints, one at each end of each of the plurality of longitudinal members, coupling the plurality of longitudinal members to form repeating triangular structures adjacent to each other.

It should be appreciated by those skilled in the art that any block diagrams herein represent conceptual views of illustrative systems embodying the principles of the present subject matter.
The present subject matter relates to farming structures for aquatic farming of multicellular organisms.
Farming structures utilized for aquatic farming typically experience stress of water waves while floating on or submerged in a water-body. Water waves usually impart irregular multidirectional stress on the farming structures. Farming structures that are conventionally utilized in aquatic farming are not substantially flexible to absorb the irregular stress of water waves. Due to the substantially low flexibility, the conventional farming structures are unable to sustain their configuration and order, and tend to collapse in water and damage under the stress of water waves. This makes the conventional farming structures for aquatic farming less durable.
The state of the art, for example disclosed in patent documents U.S. Pat. No. 7,587,991 and U.S. Pat. No. 5,309,672, relates to farming structures having a level of flexibility and/or durability. However, the conventional farming structures involve complicated assemblies which are difficult to assemble and require substantially large amount of material. Such conventional floating structures involve substantially high costs and their assembly is substantially complex and laborious. In addition, such conventional farming structures are not designed to adapt its shape to that of the water waves in the water-body and are not modularly expandable.
Thus, there is a need of a farming structure for aquatic farming, which is substantially flexible, capable of adapting its shape to that of the water waves, sustaining its configuration and intrinsic shape without collapsing under the stress of water waves, easy to assemble, modular and involves low costs.
The present subject matter describes farming structures for aquatic farming of multicellular organisms. The farming structures of the present subject matter are substantially flexible such that their configuration and the intrinsic shape are maintained under the influence of water waves while the farming structure is floating on or submerged in a water-body for the purposes of aquatic farming. In addition, the farming structure of the present subject matter is modular, scalable and easy to assemble, and is of low cost.
The farming structure of the present subject matter is formed by inter-connecting a plurality of longitudinal members through a plurality of flexible joints. The longitudinal members are inter-connected to form repeating triangular structures adjacent to each other. Each flexible joint forms a vertex of at least one of the triangular structures and couples two or more longitudinal members. The farming structure can be easily extended modularly to any desirable extent in the plane of the farming structure. Configuration of the farming structure of the present subject matter draws analogy from a lattice structure whose basis is a triangle.
In the farming structure of the present subject matter, the flexible joints are configured in a manner that offers flexibility to the each longitudinal member in one or more or all directions. With one flexible joint at each vertex, each triangular structure maintains its intrinsic shape under the stress of water waves. In an implementation, the flexible joints may include pivot joints, hinge joints, ball-socket joints or other similar joints or a combination thereof. The flexible joints can be attached to the longitudinal members by bolting, welding, cementing with appropriate adhesive compounds or any other attaching ways conventionally known to a skillful person.
The farming structure of the present subject matter may be utilized for floating-type aquatic farming or submerged-type aquatic farming. In the floating-type aquatic farming, the farming structure either floats on or partially below the surface of water in a water-body, and in the submerged-type aquatic farming, the farming structure is submerged or immersed in water in a water-body but floats at a certain distance or level below the water surface. In an implementation, for the purpose of flotation of the farming structure below the water surface, the farming structure may be coupled to a flotation means, such as buoys. In one implementation, for the purpose of flotation of the farming structure either on or partially below the water surface, the longitudinal members of the farming structure may be floatable.
With the repeating triangular structures and flexible joints, the farming structure of the present subject matter is substantially flexible and capable of adapting itself to the wave profiles that occur on the water surface or inside the water bodies. Thus, the farming structure of the present subject matter has a substantially less tendency to collapse or get damaged in the water-body under the influence of stress of the water waves.
These and other advantages of the present subject matter would be described in greater detail in conjunction with the following figures. It should be noted that the description and figures merely illustrate the principles of the present subject matter. Additionally, the word “connected” or “coupled” is used throughout for clarity of the description and can include either a direct connection or an indirect connection.
The farming structure 1 of the present subject matter includes longitudinal members 3 coupled with each other through flexible joints 4. The longitudinal members 3 are coupled to form repeating triangular structures 5 that form the entire farming structure 1. It may be understood that the longitudinal members 3 form the sides of the triangular structures 5 and the flexible joints 4 are at the vertices of the triangular structures 5. In an implementation, each longitudinal member 3 forms the side of at least one triangular structure 5 and each flexible joint 4 is at one vertex of at least one triangular structure 5. Further, in an implementation, at each flexible joint 4 at least two longitudinal members 3 are coupled, as shown in
Each flexible joint 4 provides flexibility in one or more or all directions to the each of the longitudinal members 3 coupled thereat. In an implementation, the flexible joint 4 is configured to provide movements to the respective longitudinal member 3 in a vertical plane and a horizontal plane about itself. The flexible joints 4, the coupling of the longitudinal members 3 thereat and the movements of the longitudinal members 3 are explained in the descriptions of
In an implementation, the longitudinal members 3 may be columns or bars with one dimension longer than the other two dimensions. In an implementation, the longitudinal members 3 may be rigid columns or bars with substantially equal lengths and having cross-sections of substantially circular or polygon shapes. Further, in an implementation, the longitudinal members 3 may be made of plastics, metals, composites or a combination thereof.

The connection element 7, as shown in
As shown in
In an implementation, the first coupling element 10 may be fixedly coupled at a cross-section of the longitudinal member 3. The fixed coupling may be such that there is insignificant relative movement between the first coupling element 10 and the longitudinal member 3. In case the longitudinal member 3 is hollow, the cross-section of the longitudinal member 3 is sealed to fix the first coupling element 10. The sealing on the cross-section of the longitudinal member 3 also prevents entering water in the longitudinal member 3.
In an implementation, the longitudinal member 3 may be provided with an intermediate coupling element 12, as shown in
In an implementation, the first coupling element 10 may be directly bolted, welded, cemented, fixed with an adhesive or fixed by any other conventional means at the longitudinal member 3.
Further, in an implementation, the coupling of the first coupling element 10 and the second coupling element 11 forms a first pivot joint which allows movement of the first coupling element 10 in the vertical plane about the second coupling element 11. For forming the first pivot joint, the first coupling element 10 includes a first extended element 13 and the second coupling element 11 includes an opening 14 to accommodate the first extended element 13, as shown in
Further, in an implementation, the coupling of the second coupling element 11 and the hub element 6 forms a second pivot joint which allows movement of the second coupling element 11 in the horizontal plane about the hub element 6. For forming the second pivot joint, the second coupling element 11 includes a second extended element 21 with a hole 22 configured along a vertical axis 23. The second coupling element 11 is pivoted onto the hub element 6 through the hole 22 at the second extended element 21. In an assembled state of the flexible joint 4 with the longitudinal member 3, at the second pivot joint, the second coupling element 11 and hence the longitudinal member 3 is movable in the horizontal plane about the vertical axis 23 aligned with a longitudinal axis of the hub element 6.
Further, in an implementation, at each flexible joint 4, the coupling of the connection elements 7 at the hub element 6 is secured through a securing means, such as a nut 24, as shown in
In an implementation, the securing means also includes a spacer element 25 which is positioned on the hub element 6 before securing the nut 24. In an implementation, the spacer element 25 may be a sleeve or a washer of a predefined length based on the number of connection elements 7 coupled at the hub element 6. The spacer element 25 is configured to fill the space between the nut 24 and the top most connection element 7 at the hub element 6. The spacer element 25 facilitates in preventing any jumping movement or rattling of one or more connection elements 7 at the hub element 6 during the aquatic farming. In an implementation, the spacer element 25 may be made of a single piece or multiple pieces.

The connection element 27, as shown in
In an implementation, the first end 28 of the connection element 27 is fixedly coupled at a cross-section of the longitudinal member 3 such that the is insignificant relative movement between the connection element 27 and the longitudinal member 3. As shown in
In an implementation, as shown in
Further, in an implementation, at each flexible joint 4, the coupling of the connection elements 27 at the hub element 26 is secured through a securing means, such as a top cover 36 and a bottom cover 36′, as shown in
Although
Configuring the farming structure 1 in the form of repeatable triangular structures 5 and with flexible joints 4, particularly according to the embodiments shown in
For the purpose of aquatic farming in the water-body 2, the farming structure 1 of the present subject matter may be floatable on the surface of water or partially below the surface of water or at a predefined distance below the surface of water. In an implementation, the farming structure 1 may be intrinsically floatable or may be floatable through an external flotation means.
In an implementation, the each buoy 37 may be of predefined buoyancy. The number and the positions of buoys 37 on the farming structure 1 are such that farming structure 1 floats at the predefined distance below the surface of water. It may be understood that the predefined buoyancy, the number and the position of the buoys 37 on the farming structure 1 depend on the weight and density of the farming structure 1. With the farming structure 1 floating at the predefine distance below the surface of water, for the purpose of aquatic farming the top of the farming structure 1 is accessible, for example, using a low-draft boat.
In an implementation, the farming structure 1 may be intrinsically floatable on or partially below the surface of water on the water-body 2. In an implementation, the longitudinal members 3 of the farming structure 1 may be floatable. For this, the each longitudinal member 3 may be hollow or solid and may include internal or external reinforcements that provide rigidity to the longitudinal member 3 and facilitate in making the longitudinal member 3 float. Examples of such internal or external reinforcements could be internal braces, longitudinal ribs, and poly urethane foam filling.
For the cultivation of multicellular organisms on the farming structure 1, the supporting means 41 are seeded with spores or vegetative propagules of a variety of seaweed. The seeded supporting means 41 are attached on the triangular structures 5 of the farming structure 1 and the seaweeds are allowed to grow in water for a predefined length of time based on the variety of seaweed. After this, the well grown seaweeds are harvested from the supporting means 41 of the farming structure 1 and the supporting means 41 are reseeded for next cycle of cultivation. In an implementation, the operation of seeding and harvesting of seaweeds on the farming structure 1 may be performed automatically or manually.
The farming structure 1 of the present subject matter is substantially flexible to maintain its overall 2-dimensional shape while the farming structure 1 is floating on or in the water-body 2 for aquatic farming. The farming structure 1 of the present subject matter is easy to assemble and disassemble, and offers substantial improvements in productivity of aquatic multicellular organisms.
Although embodiments for the farming structure 1 have been described in language specific to structural features, it is to be understood that the invention is not necessarily limited to the specific features described.
