Description

Technical Field

[0001] This invention relates to the field of deep-sea aquaculture technology, specifically a deep-sea aquaculture and transfer platform for pearl grouper. Background Technology

[0002] Deep-sea aquaculture can further expand the development space of marine fisheries, alleviate the pressure on resources and the ecological burden of my country's nearshore waters, and promote the overall development of my country's marine economy. Deep-sea waters are vast, have excellent water quality, and superior water exchange conditions. Wastewater discharge is far within the self-purification capacity of the sea area, resulting in a large environmental capacity redundancy and minimal impact on the surrounding waters. Furthermore, with the expansion of marine fisheries development space, nearshore aquaculture density can be effectively controlled, reducing nearshore marine aquaculture pollution discharge. This is conducive to the restoration of nearshore marine ecosystems and marine environmental protection, and also helps to achieve the restoration and sustainable utilization of key nearshore biological resources.

[0003] As an important economic species in China, the pearl grouper has high requirements for its aquatic environment. Traditional farming methods, such as cement ponds, elevated ponds, and fish rafts, not only make it prone to disease outbreaks and difficult to control, but also put significant pressure on the surrounding environment. Furthermore, the pearl grouper has small, thin, and soft scales that are easily lost with slight movement and produce mucus. This is especially problematic when dealing with large numbers of fish and long transportation times, making it difficult to guarantee a high survival rate during transport. Summary of the Invention

[0046] To make the objectives, technical solutions, and advantages of this technical solution clearer, the following detailed description, in conjunction with specific embodiments, further illustrates this technical solution. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this technical solution.

[0047] To address the difficulties in transporting pearl grouper and the resulting quality decline due to oxygen deficiency during transport, this invention proposes a deep-sea aquaculture and transport platform for pearl grouper. The main body of the platform is a hull, and multiple aquaculture compartments 10 are arranged along the length of the hull. The aquaculture compartments 10 form the basis for the transport and aquaculture of pearl grouper.

[0048] like Figure 1 As shown, a drainage column 11 is installed at the bottom of the aquaculture tank 10. The function of the drainage column 11 is to discharge excess water in the aquaculture tank 10 to the outside of the ship's side 30 through the lower overflow pipe 13. The overflow interface at the lower part of the drainage column 11 is connected to the lower overflow pipe 13. An upper overflow pipe 14 is installed on the upper side wall of the aquaculture tank 10. The upper overflow pipe 14 and the lower overflow pipe 13 together form the overflow pipe system of a single aquaculture tank 10. A water inlet pipe 12 is installed on the side wall of the aquaculture tank 10. The function of the water inlet pipe 12 is to transport water to the aquaculture tank 10 through an external water input system or circulating water brought by the oxygenation system 20. In this embodiment, the water inlet pipe 12 is provided with multiple independent branch pipes, and each branch pipe is provided with an individually controlled valve.

[0049] like Figure 2 As shown, the drainage column 11 at the bottom of the aquaculture tank 10 has a multi-stage structure. Part of the drainage column 11 extends into the aquaculture tank 10 and has drainage holes 111. A fish suction pipe 15 is connected to the disc-shaped area below the drainage column 11. That is, after closing the lower overflow pipe 13, opening the fish suction pipe 15 allows the pearl grouper in the aquaculture tank 10 to be transported to the offshore aquaculture area through the fish suction pump installed on the fish suction pipe 15.

[0050] like Figure 3 As shown, Figure 3This is a schematic diagram of the oxygenation system 20 of the aquaculture tank 10. In this embodiment, the active oxygenation system 20 installed in the aquaculture tank 10 includes an oxygenation pump 21 and an oxygen cone 22. The oxygenation pump 21 has two output ends. The first output end of the oxygenation pump 21 is directly connected to the aquaculture tank 10 through a pipeline, meaning that after the oxygenation pump 21 is turned on, some oxygen is directly injected into the water body of the aquaculture tank 10 through the pipeline. In the oxygenation system 20, some of the oxygen output by the oxygenation pump 21 is transported to the oxygen cone 22 through a pipeline. In this embodiment, the oxygen cone 22 forms a circulation pipeline with the aquaculture tank 10 through a pipeline. An oxygen cone pump 23 is installed on the circulation pipeline between the oxygen cone 22 and the aquaculture tank 10. The function of the oxygen cone pump 23 is to provide the driving force for water circulation. When the oxygen content in the aquaculture tank 10 is low, the oxygen pump 21, oxygen cone 22 and oxygen cone pump 23 are turned on. The oxygen output by the oxygen pump 21 enters the oxygen exchange structure in the oxygen cone 22. The water output from the aquaculture tank 10 is driven by the oxygen cone pump 23 into the oxygen exchange structure of the oxygen cone 22 for oxygen exchange. After the oxygen exchange is completed, the oxygen-enriched water is circulated back into the aquaculture tank 10 through the pipeline to achieve the effect of actively oxygenating the water in the aquaculture tank 10.

[0051] like Figure 4 and Figure 5 As shown, the water input system in this embodiment can transport seawater around the hull 30 to the aquaculture tank 10. The seawater is rich in oxygen and various essential organic matter and microorganisms, which benefits the optimization and replacement of the water inside the aquaculture tank 10. When the water input system is activated, the aquaculture tank 10 forms a seawater state similar to natural conditions, which is conducive to the survival and growth of the pearl grouper. In this embodiment, the water input system is a seawater inlet grille 40, which is located on the side of the hull 30, preferably on an inclined surface other than the front or side of the hull 30, and preferably on the bow side. The seawater inlet grille 40 on the side of the hull 30 has a large cavity at its rear, which is connected to the aquaculture tank 10 via a pipe. When seawater enters the cavity after passing through the seawater inlet grille 40, the seawater can be forced into the aquaculture tank 10 non-powered by the pressure difference between the inner and outer aquaculture tanks 10 and the cavity.

[0052] like Figure 6 As shown, an active cleaning system 50 is provided on the side of the seawater inlet grille 40 near the hull. The active cleaning system 50 includes a guide 51, a drive mechanism 52, a transmission chain 53, a slider 54, and a locking gear 55. The guide 51 is located near the seawater inlet grille 40 and parallel to the extension direction of the seawater inlet grille 40. The slider 54 is slidably connected to the guide 51. The drive mechanism 52 is connected to the slider 54 through the transmission chain 53 to drive the slider 54 to slide linearly on the guide 51. The locking gear 55 is connected to the slider 54 through a rotating shaft. The locking gear 55 is adapted to and cooperates with the seawater inlet grille 40.

[0053] In this embodiment, one cleaning process of the active cleaning system 50 is the movement of the card slot gear 55 from the front of the hull 30 to the rear of the hull 30. Since the water input system is activated during the movement of the hull, and the main body of the seawater inlet grille 40 is a grille structure, the seawater inlet grille 40 is easily covered by seabed flora and fauna, such as seaweed or fish, thus restricting water intake. Therefore, the active cleaning system 50 can actively clean up the aforementioned debris and coverings.

[0054] When the hull is running at a low speed, the opening of the water input system decreases, and the active cleaning system 50 is activated. The drive mechanism 52 drives the slider 54 to move on the guide 51 via the transmission chain 53. In this embodiment, the guide 51 is a plastic slide rail. During the movement of the slider 54, since the locating gear 55 is adapted to and cooperates with the seawater inlet grille 40, the teeth of the locating gear 55 can enter the gaps of the seawater inlet grille 40 one by one, pushing away the debris stuck in the gaps of the seawater inlet grille 40 and the debris on the surface of the seawater inlet grille 40. As the locating gear 55 moves from front to back, and the hull moves forward at the same time, the debris covering the surface of the seawater inlet grille 40 and the debris stuck in the seawater inlet grille 40 are cleaned away. The debris will slide down the hull 30, thereby achieving the expected goal. Preferably, one side of the slider 54 is adjacent to the seawater inlet grille 40, and one side of the slider 54 is a blade 541 for cleaning the seawater inlet grille 40 by sliding. As the slider 54 moves, the blade 541 crushes the object stuck in the grid plate and enters the water input system with the seawater.

[0055] like Figure 7 As shown, in summary, the seawater input through the seawater inlet grille 40 enters the aquaculture tank 10 after passing through the buffer assembly 60. This has two advantages: firstly, the seawater pressure is buffered; secondly, larger organisms and impurities mixed in with the seawater in the seawater inlet grille 40 can be filtered by the buffer assembly 60, allowing relatively pure seawater to enter the aquaculture tank 10. Simultaneously, the oxygenation system 20 and the water input system share a common delivery pipeline to simplify the piping.

[0056] like Figure 8 As shown, a buffer assembly 60 is installed on the pipeline between the water input system and the aquaculture tank 10. The buffer assembly 60 includes a buffer well 61, a filter screen 62, a buffer well inlet pipe 63, and a buffer well outlet pipe 64. The top of the buffer well 61 can be switched between open and closed states, and the filter screen 62 is located in the middle of the buffer well 61. The buffer well inlet pipe 63 is used to connect the water input system and the buffer well 61, and the connection point between the buffer well inlet pipe 63 and the buffer well 61 is located at the upper part of the filter screen 62. The buffer well outlet pipe 64 is used to connect the buffer well 61 and the aquaculture tank 10, and the connection point between the buffer well outlet pipe 64 and the buffer well 61 is located at the lower part of the filter screen 62.

[0057] Combination Figure 7 and Figure 8 As shown, the output end of the buffer assembly 60 and the output end of the oxygenation system 20 share the oxygenated water delivery pipeline; a first auxiliary pipeline 71 is also provided between the oxygenated water delivery pipeline and the output pipeline 72 of the oxygenation system, and a first valve body 73 is provided on the first auxiliary pipeline 71; a second valve body 74 is provided on the output pipeline 72 of the oxygenation system; a third valve body 75 is provided on the input pipeline of the oxygenation system 20; and a fourth valve body 76 is provided on the pipeline between the water input system and the buffer assembly 60. The purpose of the above-mentioned distributed auxiliary pipelines and valve bodies is to switch the operating conditions of this transfer platform under different states. In this embodiment, an oxygen content sensor 16 is provided in the aquaculture tank 10 to detect the oxygen content of the water in the aquaculture tank 10 in real time.

[0058] Specifically, the usage method of the pearl grouper deep-sea aquaculture and transfer platform described herein is as follows:

[0059] When the platform moves forward at a speed greater than the first threshold: the fourth valve 76 opens, the first valve 73, the second valve 74 and the third valve 75 close, and the water input system supplies water to the aquaculture tank 10 and overflows the water from the aquaculture tank 10 through the overflow pipe;

[0060] When the platform moves forward at a speed less than the first threshold and greater than the second threshold: the second valve body 74, the third valve body 75 and the fourth valve body 76 open, the first valve body 73 closes, the water input system delivers water to the aquaculture tank 10, and at the same time the oxygenation system 20 oxygenates the water delivered to the aquaculture tank 10.

[0061] When the platform moves forward at a speed less than the second threshold: the first valve body 73 and the fourth valve body 76 are closed, the second valve body 74 and the third valve body 75 are opened, and the oxygenation system 20 oxygenates the water transported to the aquaculture tank 10.

[0062] Water input system cleaning: Close the valve of the inlet pipe 12 of the aquaculture tank 10, close the first valve 73 and the second valve 74, open the fourth valve 76, open the top of the buffer well 61, and the active cleaning system 50 is activated. At this time, the water in the aquaculture tank 10 is discharged through the oxygen cone pump 23 and then through the buffer component 60 and discharged from the seawater inlet grille 40. During this process, the ship stops.

[0063] Buffer assembly 60 backflushing: Open the first valve body 73, close the second valve body 74, open the third valve body 75, close the fourth valve body 76, open the top of the buffer well 61, and output the water in the aquaculture tank 10 to the filter screen plate 62 through the oxygen cone pump 23, and backflushing the filter screen plate 62. The water in the aquaculture tank 10 is output to the oxygen cone 22 through the lower overflow pipe 13, and after passing through the oxygen cone 22, it enters the buffer assembly 60. The water and impurities backflushing the filter screen plate 62 in the buffer well 61 finally discharge from the buffer well 61 into the sea.

[0064] The coordination of the above-mentioned pearl grouper deep-sea aquaculture and transfer platform under various working conditions can provide better water conditions for the pearl grouper in the aquaculture tank 10, optimize the aquaculture and transfer environment, and provide a platform for the connection and transfer of live water for pearl grouper, so as to ensure the quality and survival rate of fish fry.
