Description

Technical Field

[0001] The present disclosure relates to the field of marine aquaculture equipment, and more particularly, to a system for transporting fry on water. Background Art

[0002] Deep-sea aquaculture generally uses large floating cages. The floating cages rely on buoyancy to float in seawater and are anchored by a mooring chain system. However, they still move constantly under the action of waves and currents. Fry are generally transported by live fish transport ships. The live fish transport ship moves to the floating cage and releases the fry into the floating cage for aquaculture.

[0003] In the related art, for the release of fry, generally a fish net and a crane are used. The fry are loaded into multiple fish nets in batches, and the fish nets are dropped from the live fish transport ship into the floating cage by the crane. However, this method takes a long time. When the water environment is relatively harsh, such as when the wind and waves are large, the live fish transport ship is easily affected by the wind and waves and sways, resulting in the crane being unable to accurately release the fry in the fish net into the floating cage. In addition, there is also a situation where the fry fall out of the fish net during the swaying process, which is extremely likely to damage the fry, reduce the survival rate of the fry, and is not conducive to saving economic costs. Summary of the Utility Model

[0004] The purpose of the present disclosure is to provide a system for transporting fry on water, which can achieve accurate release of fry to at least partially solve the above technical problems.

[0013] The second joint is configured to have a diameter larger than the length of the conveying member in the first direction, so that the conveying member can be inserted into the interior of the second joint.

[0014] Optionally, both the first joint and the second joint are constructed as flexible bellows; the first joint is connected to the fish outlet through a flange, and the second joint is connected to the fish inlet through the flange; the conveying member is constructed as a hollow pipeline or a U-shaped pipeline with an upward opening.

[0034] The following details the specific implementation of the present disclosure in conjunction with the drawings. It should be understood that the specific implementation described herein is only for explaining and understanding the present disclosure, and does not limit the present disclosure.

[0035] In the present disclosure, unless otherwise stated, "inner" and "outer" refer to the inside and outside of the contour of the corresponding component. In addition, the terms "first" and "second" used in the present disclosure are used to distinguish one element from another element, without sequence and importance. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0036] According to Figures 1 to 5 As shown, an embodiment of the present disclosure provides a system for transporting fry on water. The system includes a transportation device 1, a breeding device 2, and a connection component 3. The transportation device 1 may include a fish suction pump 11 and a fish outlet 10. The fish suction pump 11 is connected to the fish outlet 10 through a pipeline. The transportation device 1 is used to transport fry. The fish suction pump 11 is used to pump the fry located inside the transportation device 1. The breeding device 2 may include a fish inlet 20. The breeding device 2 is used to breed fry. The connection component 3 may include a conveying member 32 and a flexible joint. Opposite ends of the conveying member 32 are respectively connected to the fish inlet 20 and the fish outlet 10 through the flexible joint, and are used to transport fry from the transportation device 1 to the breeding device 2 through the connection component 3.

[0037] Through the above technical solution, the connection component 3 is provided to connect the transportation device 1 and the breeding device 2. The fry located inside the transportation device 1 is pumped into the breeding device 2 by the fish suction pump 11, which can greatly save the fry release time. The connection component 3 includes a conveying member 32 and a flexible joint. Opposite ends of the conveying member 32 are respectively connected to the fish inlet 20 and the fish outlet 10 through the flexible joint. When the water waves are too large on the water, the flexible joint can shake together with the transportation device 1 and the breeding device 2 under the impact of the waves. The ductility of the flexible joint can prevent the transportation device 1 and the breeding device 2 from separating due to the shaking caused by the waves during docking, and realize the accurate release of fry. Prevent the fry from falling during the release process, with better environmental adaptability, and more reliability and safety in use.

[0038] Among them, the transportation device 1 can adopt a transportation ship, and the breeding device 2 can adopt a floating cage. Regarding the structures of the transportation ship and the floating cage, those skilled in the art can refer to and retrieve existing literature, and the present disclosure will not elaborate herein.

[0039] Both the fish inlet 20 and the fish outlet 10 can be configured as round holes or rectangular holes. The present disclosure is not limited thereto.

[0040] In some feasible embodiments, for example, referring to Figure 2As shown, the vertical height of the fish outlet 10 can be greater than the vertical height of the fish inlet 20, so that the connecting assembly 3 is arranged at an angle. For example, the height of the fish outlet 10 can be 50 cm greater than the height of the fish inlet 20. With this arrangement, when fry are pumped to the breeding device 2 via the transport device 1, the fry can be accelerated by gravity within the inclined connecting assembly 3 and slide into the breeding device 2, effectively preventing fry blockage during transportation and improving reliability.

[0041] In some embodiments, for example, referring to Figure 1 and Figure 2 As shown, the fish inlet 20 can be located between the bottom and top of the aquaculture device 2. To ensure the survival rate of the fry, the aquaculture device 2 is typically partially submerged in water to provide a good living environment for the fry. The portion of the aquaculture device 2 submerged in water is typically determined by its structure and material, as well as the number and weight of the fry being cultured. Therefore, the fish inlet 20 is positioned between the top and bottom of the aquaculture device 2. For example, the fish inlet 20 can be positioned 50 cm above the water surface between the top and bottom of the aquaculture device 2. This prevents the fry from escaping the aquaculture device 2 through the fish inlet 20, facilitates installation of the connecting assembly 3 by the operator, and prevents the fry from falling and being injured when entering the aquaculture device 2 through the fish inlet 20. Of course, the fish inlet 20 can also be located below the water surface between the top and bottom of the aquaculture device 2. In this case, a stop assembly is required at the fish inlet 20. To facilitate installation of the flexible joint, the flexible joint and the aquaculture device 2 are typically connected via a flange 4. The flange 4 is typically located at the fish inlet 20 to facilitate quick assembly of the flexible joint. The stop assembly can include a flange cover and a support frame 41 for securing the flange cover. The support frame 41 is connected to the aquaculture device 2. The flange cover can include a ring 42 and a separation net 420. The ring 42 has a plurality of mating holes 421 arranged circumferentially and corresponding to the assembly holes 40 of the flange 4, so that the ring 42 can mate with the flange 4. The separation net 420 is connected to the ring 42 to prevent the fry from escaping the aquaculture device 2. Of course, when the fish inlet 20 is located 50 cm above the water surface between the top and bottom of the aquaculture device 2, a stop assembly can also be provided to further ensure that the fry do not escape the aquaculture device 2. This disclosure is not specifically limited to this, as long as the fry can be transported.

[0042] In some embodiments, for example, referring to Figures 1 to 4As shown, the flexible joint may include a first joint 30 connected to the fish outlet 10 and a second joint 31 connected to the fish inlet 20, and the first joint 30 and the second joint 31 are connected by a conveying member 32; the first joint 30 may be configured to have a diameter smaller than the length of the conveying member 32 along the first direction X, so that the first joint 30 can be inserted into the interior of the conveying member 32; the second joint 31 may be configured to have a diameter larger than the length of the conveying member 32 along the first direction X, so that the conveying member 32 can be inserted into the interior of the second joint 31. Configuring the first joint 30 to have a diameter smaller than the length of the conveying member 32 along the first direction X and the second joint 31 to have a diameter larger than the length of the conveying member 32 along the first direction X can ensure the safety of the fry during transportation; if the diameter of the first joint 30 is larger than the length of the conveying member 32 along the first direction X, it will cause the fry to collide with the end of the conveying member 32 during transportation, damaging the fry and reducing the survival rate of the fry; if the diameter of the second joint 31 is smaller than the length of the conveying member 32 along the first direction X, it will cause the fry to collide with the second joint 31 during transportation, damaging the fry and also causing the fry to become blocked, which is not conducive to transportation.

[0043] The first direction X is perpendicular to the extending direction of the conveying member 32 towards the fish inlet 20.

[0044] Of course, the diameter of the first joint 30 may be the same as the length of the conveying member 32 along the first direction X, and the diameter of the second joint 31 may also be the same as the length of the conveying member 32 along the first direction X, which can also achieve the safe transportation of the fry. The present disclosure does not make specific limitations in this regard, and those skilled in the art can make adaptive adjustments according to the actual situation.

[0045] The connection manner of the conveying member 32 with the first joint 30 and the second joint 31 can be adaptively adjusted according to the actual situation. For example, the first joint 30 and the second joint 31 can be respectively connected to the opposite ends of the conveying member 32 by connecting bolts; the first joint 30 and the second joint 31 can also be connected to the conveying member 32 by welding. The present disclosure is not limited thereto.

[0046] Optionally, both the first joint 30 and the second joint 31 can be configured as flexible bellows. The first joint 30 can be connected to the fish outlet 10 through the flange 4, and the second joint 31 can be connected to the fish inlet 20 through the flange 4. The conveying member 32 can be configured as a hollow pipeline or a U-shaped pipeline with an opening facing upward. For example, the conveying member 32 can be configured as a concave structure or a hollow cylindrical structure. The present disclosure is not limited thereto, as long as the transportation of fry can be achieved. Both the first joint 30 and the second joint 31 are configured as flexible bellows, which can further improve the plastic deformation ability of the first joint 30 and the second joint 31, so as to further improve the resistance of the first joint 30 and the second joint 31 to the impact of water waves, and avoid the first joint 30, the second joint 31 and the conveying member 32 from breaking and separating during the shaking process when the transportation device 1 and the breeding device 2 are docked through the connecting component 3. Among them, in order to prevent fry from escaping from the fish outlet 10 during transportation and to prevent fry from escaping from the fish inlet 20 during breeding, in the normal state, the flanges 4 at the fish inlet 20 and the fish outlet 10 can use flange covers to close the fish inlet 20 and the fish outlet 10. When it is necessary to transport fry from the transportation device 1 to the breeding device 2, the flange cover is removed, the first joint 30 is connected to the fish outlet 10 through the flange 4, the second joint 31 is connected to the fish inlet 20 through the flange 4, and then the first joint 30 and the second joint 31 are respectively connected to the conveying member 32; after the transportation is completed, the conveying member 32, the first joint 30 and the second joint 31 are removed, and then the flange cover is connected to the flange 4 to close the fish outlet 10 and the fish inlet 20. Of course, the flange 4 may not be provided at the fish inlet 20. When it is necessary to transport fry, the second joint 31 can be directly extended into the breeding device 2 through the fish inlet 20, and the transportation of fry can also be achieved. The present disclosure does not make specific limitations on this.

[0047] It can be understood that the conveying member 32 can be made of channel steel. The thickness of the channel steel can be between 1.5 mm and 3 mm to improve the bearing capacity of the conveying member 32. The length of the channel steel along the first direction X can be between 0.5 m and 1 m to increase the number of fry that the conveying member 32 can accommodate. The height of the channel steel in the vertical direction can be 0.5 m to ensure that the fry will not fall out of the conveying member 32 during transportation. The flexible bellows can be made of HDPE material. The present disclosure does not make specific limitations on this.

[0048] Of course, for the convenience of observing the transportation state of fry in the conveying member 32 in real time, a fish viewing port 320 may be provided on the conveying member 32. For example, when the conveying member 32 is configured as a U-shaped pipeline with an upward opening, the opening forms the fish viewing port 320. When the conveying member 32 is configured as a hollow cylindrical structure, a fish viewing port 320 extending axially may be opened at the top of the cylindrical structure. To prevent the fry from jumping out of the fish viewing port 320 during transportation, a transparent window may be provided at the fish viewing port 320. The present disclosure does not make specific limitations in this regard, and those skilled in the art can make adaptive adjustments according to actual needs.

[0049] In some implementable ways, for example, referring to Figure 1 and Figure 2 as shown, a first flexible member 12 detachably connected to the conveying member 32 may be provided on the transportation device 1, and a second flexible member 22 detachably connected to the conveying member 32 may be provided on the breeding device 2. By providing the first flexible member 12 and the second flexible member 22, the stability and safety of the conveying member 32 can be further improved, enabling the conveying member 32 to have a stronger bearing capacity, and avoiding the fracture and separation of the conveying member 32 from the first joint 30 and the second joint 31 when the weight of the fry being transported is too much for the conveying member 32 to bear. Of course, by using the first flexible member 12 and the second flexible member 22, during the docking process of the transportation device 1 and the breeding device 2 through the connection assembly 3, under the action of the wave, the first flexible member 12 and the second flexible member 22 can sway following the swaying of the transportation device 1 and the breeding device 2, so as to avoid damage to the transportation device 1, the conveying member 32, and the breeding device 2 caused by using a rigid structure.

[0050] Optionally, both the first flexible member 12 and the second flexible member 22 may be configured as steel wires, or may be configured as hemp ropes. It can be understood that one of the first flexible member 12 and the second flexible member 22 may be configured as a steel wire rope, and the other may be configured as a hemp rope or other adaptable structures. The present disclosure does not make specific limitations in this regard.

[0051] In some implementable ways, for example, referring to Figure 5 as shown, an operation platform 21 may further be provided on the outer sidewall of the breeding device 2. The operation platform 21 may be located below the fish inlet 20. When it is necessary to dock the transportation device 1 and the breeding device 2 through the connection assembly 3, the operation platform 21 can facilitate the operator to store installation tools, making it more convenient.

[0052] The process of fry transportation is exemplarily described in the present disclosure. For example: The operator drives the transportation device 1 near the breeding device 2 so that the distance between the transportation device 1 and the breeding device 2 does not exceed 10 m. The operator enters the water, removes the flange covers of the transportation device 1 and the breeding device 2, connects the first joint 30 to the fish outlet 10 through the flange 4, connects the second joint 31 to the fish inlet 20 through the flange 4, inserts the first joint 30 into the inside of the conveying member 32 and connects it through a connecting bolt, inserts one end of the conveying member 32 away from the first joint 30 into the second joint 31 and connects it through a connecting bolt. Finally, connect the first flexible member 12 provided on the transportation device 1 and the second flexible member 22 provided on the breeding device 2 to the opposite sides of the conveying member 32 respectively. After the installation is completed, start the fish suction pump 11. The fry located in the transportation device 1 is conveyed into the conveying member 32 under the action of the fish suction pump 11. Since the conveying member 32 is inclined between the transportation device 1 and the breeding device 2, the fry can slide down rapidly under the action of gravity into the breeding device 2. The operator can observe the conveying situation in real time through the fish viewing port 320 to avoid blockage of the fry during transportation. After the fry transportation is completed, remove the second joint 31, install the flange cover on the flange 4 to close the fish inlet 20 of the breeding device 2 to prevent the fry from escaping from the fish inlet 20, and remove the second flexible member 22, the first joint 30, and the first flexible member 12 to complete the disassembly.

[0053] The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0054] In addition, it should be noted that, in the above specific embodiments, the various specific technical features described can be combined in any appropriate manner without conflict. To avoid unnecessary repetition, the present disclosure does not separately describe various possible combination methods.

[0055] Furthermore, any combination can be made between the various different embodiments of the present disclosure as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
