[0029] The existing anti-skid platform openable and closable aquaculture platform is usually a fixed structure, which is connected to the seabed by fixed legs to support the platform body. Although this type of anti-skid platform openable and closable aquaculture platform has a more stable support, it is easily damaged or even scrapped when facing natural disasters such as hurricanes or heavy rains that exceed its carrying capacity, and its disaster resistance is poor.

[0030] In order to solve the above problems, the present invention proposes an anti-avoidance table-type openable and closable breeding platform 100.

[0031] Please combine Figure 1 to Figure 2 The anti-avoidance table-type openable and closable aquaculture platform 100 of this embodiment includes a platform body 1, aquaculture cages 2, an air pressure drainage device 22 and a controller. A ballast tank 11 is arranged in the platform body 1, and a water injection and drainage port 111 is provided on the ballast tank 11. A water inlet 12 and a water outlet 13 connected to the outside are provided on the platform body 1. The ballast tank 11 is connected to the water inlet 12 through a water inlet pipeline 14, and is connected to the water outlet 13 through a water outlet pipeline 15. A pump pipeline is also connected in parallel between the water inlet pipeline 14 and the water outlet pipeline 15, and a ballast pump is arranged on the pump pipeline. Water inlet 12 and water outlet 13 are respectively provided with water inlet and water outlet pipes. A first valve 152 is arranged on the outlet pipe 15 between the injection and discharge port 111 and the pump pipe, and a second valve 142 is arranged on the inlet pipe 14 between the injection and discharge port 111 and the pump pipe; a breeding cavity 21 is formed in the breeding cage 2, and a plurality of mesh holes connected to the breeding cavity 21 are formed on the outer wall of the breeding cage 2; the air pressure drainage device 22 is connected to the ballast tank 11 and is used to supply air to the ballast tank 11, and the inlet valve 141, the outlet valve 151, the first valve 152, the second valve 142, the ballast pump and the air pressure drainage device 22 are all electrically connected to the controller.

[0032] It can be understood that the water inlet pipeline 14 and the water outlet pipeline 15 can also be merged into the same pipeline near the ballast tank 11. It can also be understood that there is a main pipeline near the ballast tank 11, and the water inlet pipeline 14 and the water outlet pipeline 15 are two parallel branch pipelines respectively, and the water inlet pipeline 14 and the water outlet pipeline 15 are connected through the pump pipeline. The first valve 152 is arranged on the water outlet pipeline 15 between the pump pipeline and the main pipeline, the second valve 142 is arranged on the water inlet pipeline 14 between the pump pipeline and the main pipeline, the water inlet valve 141 is arranged on the water inlet pipeline 14 between the pump pipeline and the water inlet 12, and the water outlet valve 151 is arranged on the water outlet pipeline 15 between the pump pipeline and the water outlet 13.

[0033] The technical solution of the present invention has two water inlet and water discharge modes for the ballast tank 11. When water is inletted by gravity, the controller controls the water inlet valve 141 and the second valve 142 to open, and the water outlet valve 151 and the first valve 152 to close, so that seawater flows from the water inlet 12 through the water inlet pipeline 14 into the ballast tank 11, so that the anti-avoidance platform type openable and closable aquaculture platform 100 dives. When water is discharged, the controller controls the water outlet valve 151 and the first valve 152 to open, and the water inlet valve 141 and the second valve 142 to close, and pressurizes the ballast tank 11 through the air pressure drainage device 22, squeezes the seawater from the ballast tank 11 into the drainage pipeline, and then flows out through the water outlet 13, so that the anti-avoidance platform type openable and closable aquaculture platform 100 floats; When the ballast pump is taking in water, the controller controls the water inlet valve 141 and the first valve 152 to open, and the water outlet valve 151 and the second valve 142 to close. The ballast pump sucks seawater from the water inlet 12 into the water inlet pipeline 14, and then enters the water inlet pipeline 14 through the pump pipeline and the water outlet pipeline 15, and enters the ballast tank 11 to make the anti-avoidance platform type openable and closable breeding platform 100 dive. When the ballast pump is discharging water, the controller controls the water outlet valve 151 and the first valve 152 to open, and the water inlet valve 141 and the second valve 142 to close. The ballast pump pumps seawater out of the ballast tank 11 through the water outlet pipeline 15, and flows to the water outlet 13 through the water outlet pipeline 15 for discharge, so that the anti-avoidance platform type openable and closable breeding platform 100 floats.

[0034] The present invention injects water into the ballast tank 11 so that when a hurricane or heavy rain comes, the anti-vibration platform type openable and closable breeding platform 100 can dive below the sea surface, thereby greatly reducing the disaster-stricken area of ​​the anti-vibration platform type openable and closable breeding platform 100, reducing the damage to the anti-vibration platform type openable and closable breeding platform 100, making the anti-vibration platform type openable and closable breeding platform 100 not easily damaged, and improving the disaster resistance. At the same time, gravity water inlet and air pressure drainage and ballast pump water inlet and drainage schemes are set up. Different schemes are used for water inlet and drainage in different situations. On the one hand, it improves the applicability and safety, and on the other hand, it saves energy and improves the endurance of the anti-vibration platform type openable and closable breeding platform 100.

[0035] In one embodiment, the platform body 1 is also provided with a main drive device 30, a main propeller 31, a side drive device 32 and a side propeller 33. The main drive device 30 is used to drive the main propeller 31 to rotate and displace seawater, so as to drive the anti-avoidance platform type openable and closable breeding platform 100 to move, and the side drive device 32 is used to drive the side propeller 33 to rotate and displace seawater, so as to drive the anti-avoidance platform type openable and closable breeding platform 100 to turn.

[0036] The main drive device 30 and the main propeller 31 provide the platform body 1 with forward power, which is convenient for pushing the platform body 1 to transfer when a natural disaster is about to occur, and can also provide steering power. However, when faced with a situation where a large steering drive force is required, the side drive device 32 and the side propeller 33 can also provide steering power; secondly, when faced with severe weather but there is no need to transfer, the side drive device 32 and the side propeller 33 can provide the force provided by the side drive device 32 and the side propeller 33 to allow the anti-vibration platform to stay in place without being affected by wind and waves.

[0037] In one embodiment, a positioning system is also provided on the platform body 1, and the positioning system is used to detect the current position of the platform body 1 and send it to the controller. The controller is used to control the main drive device 30 and the side drive device 32 to drive the platform body 1 to move to the target position according to the current position.

[0038] The anti-avoidance platform-type openable and closable aquaculture platform 100 is usually located in open sea areas and is easily affected by natural factors such as wind and waves, ocean currents, and tides. The positioning system can monitor the position of the anti-avoidance platform-type openable and closable aquaculture platform 100 in real time to prevent aquaculture facilities such as aquaculture cages 2 from drifting or being lost due to natural factors, thereby reducing property losses and environmental risks. At the same time, the positioning system helps monitor the position and status of the anti-avoidance platform-type openable and closable aquaculture platform 100, facilitating timely warning and response to abnormal weather conditions. For example, when extreme weather such as typhoons and strong winds are about to occur, measures can be taken quickly to move the platform.

[0039] Specifically, there are multiple breeding cages 2, and multiple breeding cages 2 are arranged at intervals along the extension direction of the platform body 1. Multiple breeding cages 2 are arranged at intervals and independently. On the one hand, more types and more quantities of seafood can be cultured, which is convenient for independent management and control. On the other hand, the breeding cages 2 are arranged at intervals, which can reduce the risk of pathogens and parasites spreading between adjacent cages. The distance between the breeding cages 2 increases the spatial isolation of disease transmission, so that when a disease occurs in a breeding cage 2, it is not easy to spread to other breeding cages 2, thereby improving the health of the entire anti-avoidance platform type openable and closable breeding platform 100.

[0040] In one embodiment, each aquaculture cage 2 is provided with a partition plate, which is rotatably mounted on the aquaculture cage 2. The partition plate includes an open state and a closed state. When the partition plate is in the open state, the aquaculture chamber 21 is connected to the external seawater through the mesh, and when the partition plate is in the closed state, the partition plate separates the aquaculture chamber 21 from the external seawater. Normally, the partition plate is in the open state, which facilitates the real-time circulation of the seawater in the aquaculture cage 2. However, when a natural disaster occurs and the cage needs to be transferred, the partition plate needs to be closed to reduce the resistance during operation. At the same time, during the movement, the seawater conditions in some sea areas may be poor, such as a situation of heavy pollution. At this time, the partition plate needs to be closed to prevent the seafood from being contaminated and ensure the health and safety of the seafood.

[0041] Furthermore, a water circulation structure 4 is provided on the aquaculture cage 2, and the water circulation structure 4 includes a circulation pump 41, an inlet pipe 42 and an outlet pipe 43. The inlet pipe 42 and the outlet pipe 43 are both connected to the ballast tank 11. The circulation pump 41 is used to pump the seawater in the ballast tank 11 into the aquaculture chamber 21 through the inlet pipe 42 when the partition is in a closed state, and discharge the seawater in the aquaculture chamber 21 into the ballast tank 11 through the outlet pipe 43.

[0042] When evacuation is required due to natural disasters, the partition needs to be closed, and the distance and time of evacuation are relatively long. At this time, the aquaculture cage 2 is closed by the partition, and the seawater cannot be replaced in time, and the seafood is prone to necrosis. Therefore, a water circulation structure 4 is set up. Through the cooperation of the circulation pump 41, the outlet pipe 43 and the inlet pipe 42, the seawater in the aquaculture chamber 21 and the seawater in the ballast tank 11 are circulated to ensure the fresh flow of the seawater in the aquaculture chamber 21, thereby ensuring the freshness and safety of the seafood.

[0043] In one embodiment, there are multiple partitions, which are spliced ​​together to form a sealed cavity. The breeding cavity 21 is located in the sealed cavity, and a sealing gasket is provided at the edge of each partition.

[0044] The sealing gasket improves the sealing performance of the culture chamber 21 during the transfer process, thereby preventing the leakage of seawater in the culture chamber 21 from causing the death of seafood or seawater corrosion from damaging other components of the anti-table openable and closable culture platform 100, thereby improving safety.

[0045] In one embodiment, an automatic feeder 50 is correspondingly provided at each breeding net cover, a storage chamber 51 is provided in the automatic feeder 50, and the automatic feeder 50 is electrically connected to a controller, and the controller is used to control the automatic feeder 50 to put the food in the storage chamber 51 into the breeding chamber 21. The automatic feeder 50 can accurately control the amount of feed fed each time according to the time and amount pre-stored in the controller, avoid feed waste and uneven distribution problems that may occur during manual feeding, reduce feed costs, and improve feeding efficiency. At the same time, through automated feeding, the anti-avoidance table-type openable and closable breeding platform 100 can feed on demand around the clock, so that fish, shellfish and other breeding objects can continue to obtain sufficient nutrition, reduce competition and stress reactions caused by hunger, and help improve individual growth rate and breeding output.

[0046] In one embodiment, each aquaculture net cover is further provided with a fishing net cleaning system 60, the fishing net cleaning system 60 comprises a high-pressure cleaning pump and a spray pipe connected to the ballast tank 11, the high-pressure cleaning pump is used to spray the seawater in the ballast tank 11 onto the aquaculture net cage 2 through the spray pipe for cleaning; and / or, the fishing net cleaning system 60 comprises a driving member and a scrubbing member, the driving member is used to drive the scrubbing member to move along the inner wall of the aquaculture net cover and scrub the debris on the aquaculture net cover.

[0047] It is understandable that long-term use of aquaculture nets in water will accumulate seaweed, mud, shellfish and other biological attachments, hindering the flow of water. Regular cleaning of aquaculture nets can remove these obstacles, maintain the free flow of water, provide sufficient dissolved oxygen for the aquaculture, and reduce the breeding environment of pathogens, reduce the possibility of aquaculture infection, and contribute to the healthy growth of aquaculture. The aquaculture nets can be cleaned by spraying water with a high-pressure cleaning pump or wiping with a scrubbing piece. The high-pressure cleaning pump, the scrubbing piece and the driving piece can all use structures in the prior art.

[0048] In one embodiment, each aquaculture net cover is further provided with a dead fish collection device 70, which includes a driving module and a collecting module, wherein the driving module is used to drive the collecting module to move to the dead fish and collect the dead fish. If the dead fish stay in the net cage for a long time, they will decompose and release harmful substances such as ammonia nitrogen and phosphorus, and may also carry pathogens or parasites. If they remain in the net cage for a long time, they are likely to cause diseases and infect healthy aquaculture products, causing water quality deterioration and increasing the risk of eutrophication of water bodies. The dead fish collection device 70 can collect and clean dead fish in time, maintain stable water quality, and ensure the health of aquaculture products. It can be understood that the driving module can be a robot or a slide rail with a driving member, and the collecting module is usually a clamp, a manipulator, or a negative pressure adsorption member, all of which can be equipped with equipment in the prior art.

[0049] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
