[0002] Deep - sea aquaculture can further expand the development space of marine fisheries, relieve the pressure on resources and ecological load in the inshore waters of our country, and promote the overall development of our country's marine economy. The deep - sea waters are open, with excellent water quality and superior water exchange conditions. The tail water discharge is far within the self - purification capacity of the sea area, with a large environmental capacity redundancy and little impact on the nearby water environment. Moreover, with the expansion of the development space of marine fisheries, the inshore aquaculture density will be effectively controlled, the pollution discharge from inshore seawater aquaculture will be reduced, which is conducive to the restoration of the inshore marine ecosystem and marine environmental protection, and also helps to achieve the restoration and sustainable utilization of key inshore biological resources.

[0003] As an important economic fish species in China, Epinephelus fuscoguttatus♀×Epinephelus lanceolatus♂ has relatively high requirements for the aquaculture water environment. In the traditional mode, it is mostly cultured in cement ponds, high - level ponds, and fishing rafts. Not only are diseases prone to occur and difficult to control, but also the pressure on the surrounding environment is relatively large. In addition, the scales of Epinephelus fuscoguttatus♀×Epinephelus lanceolatus♂ are small, thin, and soft. It is easy to lose scales and secrete mucus with a little movement. Especially when the quantity is large and the transportation time is long, it is very difficult to ensure the survival rate during transportation. Summary of the Invention

[0046] To make the purpose, technical solutions and advantages of the present technical solution clearer and more understandable, the present technical solution will be further described in detail below in combination with specific implementation manners. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present technical solution.

[0047] To solve the problem of difficult transportation of Epinephelus fuscoguttatus♀×Epinephelus lanceolatus♂ in the prior art, and the quality decline caused by reasons such as lack of oxygen during transportation, the present invention proposes a deep-sea aquaculture transportation platform for Epinephelus fuscoguttatus♀×Epinephelus lanceolatus♂. Its main body is a hull. Along the length direction of the hull on the transportation platform, a plurality of culture tanks 10 are arranged. The culture tank 10 is the basis for the transportation and culture of Epinephelus fuscoguttatus♀×Epinephelus lanceolatus♂.

[0048] As Figure 1 shown, a drain column 11 is arranged at the bottom of the culture tank 10. The function of the drain column 11 is to discharge the excess water in the culture 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 drain column 11 is connected to the lower overflow pipe 13. At a position close to the upper part of the upper side wall of the culture tank 10, an upper overflow pipe 14 is arranged. The upper overflow pipe 14 and the lower overflow pipe 13 together form an overflow pipe system for a single culture tank 10. A water inlet pipe 12 is arranged on the side wall of the culture tank 10. The function of the water inlet pipe 12 is to convey water to the culture tank 10 through an external water input system or the circulating water brought by the oxygenation system 20. In this embodiment, the water inlet pipe 12 is provided with a plurality of independent branch pipelines, and a separately controlled valve body is arranged on each branch pipeline.

[0049] As Figure 2 shown, the drain column 11 at the lower part of the culture tank 10 is a multi-stage structure. Part of the column body of the drain column 11 extends into the culture tank 10 and is provided with drain holes 111. A fish suction pipe 15 is connected to the disc-shaped area below the drain column 11. That is, after closing the lower overflow pipe 13 and opening the fish suction pipe 15, the Epinephelus fuscoguttatus♀×Epinephelus lanceolatus♂ in the culture tank 10 can be transported to the deep-sea aquaculture area through the fish suction pump arranged on the fish suction pipe 15.

[0050] As Figure 3 shown, Figure 3Schematic diagram of the oxygenation system 20 for the aquaculture tank 10. In this embodiment, the active oxygenation system 20 provided 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 inside of the aquaculture tank 10 through a pipeline. That is, after the oxygenation pump 21 is turned on, part of the oxygen is directly injected into the water body of the aquaculture tank 10 through the pipeline. In the oxygenation system 20, part 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, and an oxygen cone pump 23 is provided 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 the water body circulation. That is, when the oxygen content in the aquaculture tank 10 is relatively low, the oxygenation pump 21, the oxygen cone 22, and the oxygen cone pump 23 are turned on. The oxygen output by the oxygenation pump 21 enters the oxygen exchange structure in the oxygen cone 22, and the water body output from the aquaculture tank 10 is driven by the oxygen cone pump 23 to enter the oxygen exchange structure in the oxygen cone 22 for oxygen exchange. After the oxygen exchange is completed, the oxygen-rich water body enters the aquaculture tank 10 through the pipeline circulation to achieve the effect of actively oxygenating the water body in the aquaculture tank 10.

[0051] As Figure 4 and Figure 5 shown, the water body input system in this embodiment can transport the seawater around the ship's side 30 to the aquaculture tank 10. The seawater is rich in oxygen and various necessary organic substances and microorganisms, which can bring benefits to the optimization and replacement of the water body inside the aquaculture tank 10. After the water body input system is turned on, the inside of the aquaculture tank 10 forms a seawater state under natural conditions, which is beneficial to the survival and growth of Epinephelus fuscoguttatus♀×Epinephelus lanceolatus♂. The water body input system in this embodiment is a seawater intake grille 40, and the seawater intake grille 40 is arranged on the side of the ship's side 30, preferably on the inclined surface that is not the front or the side of the ship's side 30, preferably opened on the side of the bow. The seawater intake grille 40 opened on the side of the ship's side 30 has a relatively large cavity at its rear, and this cavity is connected to the aquaculture tank 10 through a pipeline. When the seawater passes through the seawater intake grille 40 and enters the cavity, due to the water pressure difference between the inside and outside of the aquaculture tank 10 and this cavity, the seawater can be pressed into the aquaculture tank 10 in a non-powered manner.

[0052] As Figure 6 shown, an active cleaning system 50 is provided on the side of the seawater intake grille 40 close to the ship's interior. The active cleaning system 50 includes a guide member 51, a driving mechanism 52, a transmission chain belt 53, a slider 54, and a row of card gears 55. The guide member 51 is arranged adjacent to the seawater intake grille 40 and is parallel to the extension direction of the seawater intake grille 40. The slider 54 is slidably connected to the guide member 51. The driving mechanism 52 is connected to the slider 54 through the transmission chain belt 53 to drive the slider 54 to slide linearly on the guide member 51. The row of card gears 55 is connected to the slider 54 through a rotating shaft, and the row of card gears 55 is adapted to and cooperates with the seawater intake grille 40.

[0053] In this embodiment, the primary cleaning process of the active cleaning system 50 is the movement process of the card-removing gear 55 from the front of the ship's side 30 to the rear of the ship's side 30. Since the water body input system is turned on during the movement of the hull, and the main body of the seawater intake grille 40 is a grille structure, the seawater intake grille 40 is easily partially covered by seabed animals and plants, such as waterweeds or fish, etc., resulting in restricted water intake. Therefore, the above-mentioned sundries and coverings can be actively cleaned by the active cleaning system 50.

[0054] When the hull is running at a low speed, the opening degree of the water body input system decreases, and at the same time, the active cleaning system 50 is operated. The driving mechanism 52 drives the slider 54 to move on the guide member 51 through the transmission chain belt 53. In this embodiment, the guide member 51 is a plastic slide rail. During the movement of the slider 54, since the card-removing gear 55 is adapted to and cooperates with the seawater intake grille 40, the teeth of the card-removing gear 55 can enter the gaps of the seawater intake grille 40 one by one, pushing away the sundries stuck in the gaps of the seawater intake grille 40 and the sundries attached to the surface of the seawater intake grille 40 in the drawings. Since the card-removing gear 55 moves from front to back and the hull moves forward at the same time, the sundries covering the surface of the seawater intake grille 40 and the sundries stuck in the seawater intake grille 40 are cleaned off, and the sundries will slide down along the ship's side 30, thus achieving the expected goal. Preferably, one side of the slider 54 is close to the seawater intake grille 40, and one side of the slider 54 is a blade 541 for cleaning the seawater intake grille 40 by sliding. The blade 541 crushes the objects stuck in the grille during the movement of the slider 54 and enters the water body input system with the seawater.

[0055] As Figure 7 shown, generally speaking, the seawater input by the seawater intake grille 40 enters the cultivation tank 10 after passing through the buffer assembly 60. It has two advantages. Firstly, the seawater pressure is buffered. Secondly, the larger organisms and impurities mixed into the seawater intake grille 40 in the seawater can be filtered by the buffer assembly 60, and relatively pure seawater enters the cultivation tank 10. At the same time, the oxygenation system 20 and the water body input system share a conveying pipeline to achieve the purpose of simplifying the pipeline.

[0056] As Figure 8 shown, a buffer assembly 60 is provided on the pipeline between the water body input system and the cultivation tank 10. The buffer assembly 60 includes a buffer well 61, a filter mesh plate 62, a buffer well inlet pipe 63, and a buffer well drain pipe 64. The top of the buffer well 61 can be switched between an open and a closed state, and the filter mesh plate 62 is arranged in the middle of the buffer well 61. Among them, the buffer well inlet pipe 63 is used to connect the water body input system and the buffer well 61, and the connection part of the buffer well inlet pipe 63 and the buffer well 61 is located above the filter mesh plate 62; the buffer well drain pipe 64 is used to connect the buffer well 61 and the cultivation tank 10, and the connection part of the buffer well drain pipe 64 and the buffer well 61 is located below the filter mesh plate 62.

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

[0058] Specifically, the usage method of the deep-sea culture transfer platform for Epinephelus lanceolatus is as follows:

[0059] When the forward movement speed of the platform is greater than the first threshold: the fourth valve body 76 is opened, the first valve body 73, the second valve body 74 and the third valve body 75 are closed, and the water input system conveys water to the culture tank 10 and overflows the water body in the culture tank 10 through the overflow pipe;

[0060] When the forward movement speed of the platform is 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 are opened, the first valve body 73 is closed, and the water input system conveys water to the culture tank 10 and at the same time the aeration system 20 aerates the water body conveyed to the culture tank 10;

[0061] When the forward movement speed of the platform is 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 aeration system 20 aerates the water body conveyed to the culture tank 10;

[0062] Cleaning of the water input system: Close the valve body of the water inlet pipe 12 of the culture tank 10, close the first valve body 73 and the second valve body 74, open the fourth valve body 76, open the top of the buffer well 61, and the active cleaning system 50 operates. At this time, the water body in the culture tank 10 is output through the oxygen cone pump 23, passes through the buffer assembly 60 and then is discharged from the seawater inlet grid plate 40. During this process, the ship stops;

[0063] Recoil of the buffer assembly 60: 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, output the water body in the cultivation tank 10 to the filter screen plate 62 through the oxygen cone pump 23, and reverse-scour the filter screen plate 62. The water in the cultivation tank 10 is output to the oxygen cone 22 through the lower overflow pipe 13, enters the buffer assembly 60 after passing through the oxygen cone 22. The water body and impurities reverse-scour the filter screen plate 62 in the buffer well 61, and finally discharge from the buffer well 61 into the sea.

[0064] The cooperation of the above-mentioned Epinephelus fuscoguttatus♀×Epinephelus lanceolatus♂ deep-sea and far-sea aquaculture transfer platform under various working conditions can provide a better water body state for the Epinephelus fuscoguttatus♀×Epinephelus lanceolatus♂ in the cultivation tank 10, optimize the aquaculture transfer environment, and can provide a platform for the live water transfer connection and transfer process of the Epinephelus fuscoguttatus♀×Epinephelus lanceolatus♂ to ensure the quality and survival rate of the fry.
