Abstract

This utility model discloses a floating structure, aquaculture equipment, and aquaculture system, relating to the field of aquaculture technology. It includes a float body comprising a mounting surface and a back surface. The mounting surface is used to connect to the aquaculture cage. A rotating groove is provided on the mounting surface, with its length parallel to the mounting surface. The rotating groove divides the float body into two parts. The rotating groove is rotatably engaged with a connecting cable. When the aquaculture cage and the float body are connected, the float structure can rotate around the connecting cable as its rotation center, allowing the mounting surface and back surface to exchange positions around the connecting cable. This avoids the problem of the connecting cable being subjected to torsional force when the float structure flips due to external force, reducing the risk of damage to the connecting cable and lowering labor intensity.

Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a floating structure, aquaculture equipment and aquaculture system. Background Technology

[0002] Shellfish farming, including scallops, oysters, abalone, and pearl oysters, is an important part of my country's marine fisheries economy. Currently, common shallow-sea or tidal flat shellfish farming methods are mainly divided into two types: one is fixed-pile farming, which involves fixing wooden, cement, or metal piles to the bottom of the farming area and directly fixing the farming cages to a certain depth below the water surface; the other is longline farming, which involves setting up parallel main cables below the water surface using cables and anchoring systems, and then suspending multiple farming cages vertically along the main cables at certain intervals.

[0003] The two traditional aquaculture models mentioned above have revealed significant drawbacks in actual production, mainly in the daily maintenance of the culture cages and the health management of the shellfish. Firstly, during the shellfish's growth cycle, algae, barnacles, mussels, silt, and other biological and non-biological deposits easily adhere to the surface of the culture cage mesh. These deposits clog the mesh, severely hindering water exchange between the inside and outside of the cage, leading to reduced dissolved oxygen and accumulation of excrement, thus deteriorating the shellfish's growth environment, inhibiting their growth rate, and even causing death. Secondly, to ensure shellfish health and prevent disease, regular short-term exposure to water (sunlight) is an effective physical sterilization method.

[0004] However, regardless of whether it's fixed-pile or suspended aquaculture, when cleaning attachments or exposing the fish to sunlight is required, the entire aquaculture cage must be manually lifted from the water, transported to a work boat or shore, and then repositioned and secured in its original location. This process is entirely manual, which is not only extremely labor-intensive but also inefficient, heavily influenced by weather and sea conditions, poses safety hazards, and significantly consumes production time, increasing labor costs.

[0005] Therefore, there is an urgent need for a floating structure, aquaculture equipment, and aquaculture system that can quickly switch the position of the aquaculture cages above and below the water surface. Utility Model Content

[0006] The purpose of this invention is to provide a floating structure, aquaculture equipment, and aquaculture system. The floating body's rotating groove is rotatably connected to the connecting cable, allowing the floating structure and the aquaculture cage to rotate around the connecting cable as the rotation center, enabling the aquaculture cage below the water surface to quickly rise above the water surface.

[0007] To achieve the above objectives, this utility model provides the following solution: This utility model provides a floating structure, including: a float body, the float body including a mounting surface and a back surface, the mounting surface being used to connect with a breeding cage, the mounting surface being provided with a rotating groove, the length direction of the rotating groove being parallel to the mounting surface, the rotating groove dividing the float body into two parts, the rotating groove being rotatably engaged with a connecting cable, so that the mounting surface and the back surface can exchange positions around the connecting cable.

[0008] As one embodiment, the float body is a cuboid structure, with the two opposite long and wide faces of the cuboid structure being the mounting surface and the back surface, respectively, and the length of the rotating groove being parallel to the width direction of the cuboid structure.

[0009] As one embodiment, the mounting groove has a C-shaped cross-section.

[0010] As one implementation method, the float body is a polystyrene block.

[0011] This utility model also provides an aquaculture device, including the above-mentioned floating structure, wherein the mounting surface is connected to the aquaculture cage.

[0012] As one embodiment, a connector is also included. The float body has a connection hole, and the connector is used to pass through the connection hole and the opening on the breeding cage to connect the float body to the breeding cage.

[0013] As one embodiment, the connector is any one of a retaining ring, a connecting rope, and a metal wire.

[0014] This utility model also provides an aquaculture system, including the above-mentioned aquaculture equipment, wherein the rotating groove of the aquaculture equipment is rotatably connected to the connecting cable.

[0015] As one implementation, it also includes a limiting clip, which is disposed on the connecting cable. A positioning area is provided between two adjacent limiting clips, and the positioning area is used for installing the aquaculture equipment. The limiting clip is specifically a pipe clamp, clamp, etc., to limit the distance.

[0016] As one embodiment, counterweights are provided at both ends of the connecting cable, and the counterweights are used to submerge both ends of the connecting cable below the water surface.

[0017] The present invention achieves the following technical advantages over the prior art: The floating structure, aquaculture equipment, and aquaculture system disclosed in this utility model have a rotating groove on the mounting surface. The rotating groove can be rotatably engaged with the connecting cable. When the aquaculture cage is connected to the float body, the float structure can rotate around the connecting cable as the rotation center, so that the mounting surface and the back side can exchange their vertical positions around the connecting cable. The float body can provide sufficient buoyancy to the aquaculture cage. When the mounting surface is above the water surface, the aquaculture cage can be exposed above the water surface. When the mounting surface is below the water surface, the aquaculture cage can be submerged in the water. At the same time, the rotating groove and the connecting cable are rotatably engaged, which avoids the problem of the connecting cable being subjected to torsional force when the float structure is overturned by external force, reducing the risk of damage to the connecting cable and reducing labor intensity.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The purpose of this invention is to provide a floating structure, aquaculture equipment, and aquaculture system to solve the problems existing in the prior art. The floating structure and the connecting cable are rotated through a rotating trough, which allows the aquaculture cages below the water surface to quickly rise above the water surface.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Please refer to Figures 1-3 The floating structure disclosed in this embodiment of the present invention includes: a float body 1, the float body 1 includes a mounting surface and a back surface, the mounting surface is used to connect with the breeding cage 2, the mounting surface is provided with a rotating groove 3, the length direction of the rotating groove 3 is parallel to the mounting surface, the rotating groove 3 serves as the center of symmetry, dividing the float body 1 into two parts, and the rotating groove 3 can be rotatably engaged with the connecting cable 4. When the operator applies a turning force to any part of the float body 1, the float body 1 can rotate around the connecting cable 4, thereby exchanging the vertical position of the mounting surface and the back side around the connecting cable 4. That is, it can rotate from a state where the mounting surface is on top and the back side is on the bottom to a state where the back side is on top and the mounting surface is on the bottom, or vice versa. The float body can provide sufficient buoyancy for the aquaculture cage. When the mounting surface is above the water surface, the aquaculture cage is exposed above the water surface with the support of the float body, allowing the shellfish to be directly sun-dried and sterilized or cleaned of debris, maintaining a healthy growth environment for the aquaculture products. When the mounting surface is below the water surface, the aquaculture cage is submerged below the water surface, controlling the horizontal position of the aquaculture products in the water layer with the richest food and nutrients, thereby accelerating the growth rate of the products. Compared with the method of lifting the entire aquaculture cage out of the water and then transporting it to the work boat or shore, this application has the advantages of low labor intensity and high operation efficiency.

[0024] It is understandable that operators can directly apply a turning force to the float body 1 manually, or a work boat can be used to provide the turning force to the float body 1.

[0025] In this embodiment, the side of the breeding cage 2 and the rotating groove 3 form a receiving space for accommodating the connecting cable 4. The stability of the connection between the connecting cable 4 and the floating structure is ensured by the restriction of the breeding cage 2 and the rotating groove 3.

[0026] In this embodiment, the float body 1 is a cuboid structure. The two opposite long and wide faces of the cuboid structure are the mounting face and the back face, respectively. The length of the rotating groove 3 is parallel to the width direction of the cuboid structure. The cuboid shape of the float body 1 makes it easier to store and transport. It can be understood that: the face enclosed by the long side and the wide side of the cuboid is the long-wide face, the face enclosed by the long side and the height side is the long-height face, and the face enclosed by the wide side and the height side is the width-height face.

[0027] Furthermore, the long side of the cuboid structure is larger than the wide side, which is larger than the height. The long and wide surfaces of the cuboid can provide a larger contact area. The long and wide surfaces, as the mounting surface and the back surface, can provide a larger restoring torque for the float body 1 when they contact the water surface. When the wind and waves try to push it tilt, the water will exert a reverse force on its large surface, causing it to quickly return to its right position and preventing it from tipping over.

[0028] In this embodiment, the cross-section of the rotating groove 3 is C-shaped. The C-shaped rotating groove 3 is closer to the shape of the connecting cable 4. While ensuring that the float body 1 can rotate around the connecting cable 4, the gap between the rotating groove 3 and the connecting cable 4 is reduced, making the flipping process more stable.

[0029] As one implementation method, the float body is any one of EPS foam, EVA / EPE foam, HDPE plastic, fiberglass composite, PU polyurethane, and plastic float.

[0030] Preferably, the float body 1 is a polystyrene block.

[0031] In this embodiment, the float structure is hollow inside.

[0032] The aquaculture equipment disclosed in this embodiment includes an aquaculture cage 2 and the aforementioned floating structure. The mounting surface is connected to the aquaculture cage 2. This method of cooperating the rotating groove 3 with the aquaculture cage 2 eliminates the need to use ropes to bind the aquaculture cage 2 to the connecting cable 4, resulting in higher operability and safety.

[0033] In this embodiment, the mounting surface of the float structure matches the side dimensions of the cage body used to connect with the mounting surface.

[0034] In this embodiment, the aquaculture equipment also includes a connector. The float body 1 has a connection hole 5, and the connector is used to pass through the connection hole 5 and the opening on the aquaculture cage 2 to connect the float body 1 and the aquaculture cage 2 together. The cooperation of the connector and the connection hole 5 realizes the detachable arrangement of the float body 1 and the aquaculture cage 2. When one of them is damaged, the two can be separated so that the damaged structure can be replaced individually.

[0035] In this embodiment, the connector can be any one of a retaining ring, a connecting rope, or a metal wire.

[0036] Preferably, the connector is a retaining ring, which has the advantage of being easier to disassemble compared to other connection methods.

[0037] In this embodiment, a connecting rope can be directly used to wrap around the outside of the float body 1 and the breeding cage 2 to tie the two together.

[0038] The aquaculture system disclosed in this embodiment includes a connecting cable 4 and multiple aquaculture devices. The rotating trough 3 of the aquaculture devices is rotatably connected to the connecting cable 4. Before installation, the float structure is separated from the aquaculture cage 2. After the connecting cable 4 is placed in the rotating trough 3, the float structure is connected to the aquaculture cage 2. At this time, the surface of the aquaculture cage 2 corresponding to the installation surface covers the outside of the rotating trough 3, thereby confining the connecting cable 4 within the rotating trough 3. The connecting cable 4 can only move along the extension direction of the rotating trough 3. Multiple aquaculture devices can be connected to the connecting cable 4 in the above manner and put into use. During use, under the action of the connecting cable 4, the multiple aquaculture devices will not drift around. The float structure ensures that the cage can be submerged below the water surface or exposed above the water surface for aquaculture.

[0039] It is understandable that the work vessel has a working arm, with the fixed end of the working arm mounted on the work vessel and the free end of the working arm extending downward at an angle. The highest point of the angled part of the working arm is much higher than the water surface, and the free end of the working arm can extend downward into the aquaculture equipment. During operation, the working arm is extended into the aquaculture equipment at a position away from the connecting cable. When the working arm and the aquaculture equipment move relative to each other along the axis of the connecting cable, the angled working arm can provide an upward thrust to the aquaculture equipment to push the aquaculture equipment to turn over, thus realizing mechanized operation and further reducing labor intensity.

[0040] In this embodiment, the rotating groove 3 is a C-shaped groove, and the connecting cable 4 is elastic and can be compressed radially to produce deformation. The radial dimension of the connecting cable 4 is larger than the size of the groove opening of the rotating groove 3. During the installation process, after aligning the connecting cable 4 with the rotating groove 3, pressure is applied to the connecting cable 4. The connecting cable 4 can then deform under the pressure and the action of the groove opening of the rotating groove 3 and be squeezed into the rotating groove 3. This connection method allows the float structure to establish a connection with the connecting cable 4 without relying on the breeding cage 2, so that the float structure will not detach from the connecting cable 4 when the staff picks up the breeding cage 2.

[0041] In this embodiment, the aquaculture system also includes a limiting card 6, which is set on the connecting cable 4. There is a positioning area between two adjacent limiting cards 6. The positioning area is used to install aquaculture equipment. The limiting card 6 can axially limit the aquaculture equipment, that is, the aquaculture equipment cannot move freely along the axis of the connecting cable 4, thus avoiding the problem of aquaculture equipment piling up together.

[0042] In this embodiment, two limit cards 6 constitute a set of limit components. Each aquaculture equipment is equipped with a set of limit components, so that the distance between two adjacent aquaculture equipment can be adjusted by adjusting the distance between two adjacent sets of limit components.

[0043] In this embodiment, the limiting card 6 is a known limiting structure such as a pipe clamp or a clamp that can limit movement along the axial direction of the connecting cable 4.

[0044] In this embodiment, counterweights are provided at both ends of the connecting cable 4. The counterweights are used to submerge both ends of the connecting cable 4 below the water surface. This method can fix the aquaculture system without the need for mooring piles on the shore, allowing the location of the aquaculture system to be freely adjusted according to needs, thus improving the convenience of using the aquaculture system.

[0045] In this embodiment, the length of the connecting cable 4 without aquaculture equipment installed at both ends is sufficient to extend to the bottom of the water. Under the action of the counterweight, both ends of the connecting cable 4 can sink to the bottom of the water.

[0046] In this embodiment, the connecting cable 4 is a known structure such as a cable or a flexible tube.

[0047] In this embodiment, the size of the float structure can be adjusted according to the size of the aquaculture cage.

[0048] In this embodiment, the length of the long side of the cuboid structure is 750mm, and the height is 120mm.

[0049] In this embodiment, the cross-section of the rotating groove 3 is an arc-shaped structure with a diameter of 60mm.

[0050] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
