Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture equipment, and in particular to a large suspended culture platform for shallow-water marine delicacies and a feeding method. Background Art

[0002] Sea cucumbers, ranked as one of the eight delicacies of seafood, are a time-honored seafood delicacy. With the improvement of living standards and health awareness, the nutritional and health benefits of sea cucumbers have been increasingly recognized by consumers, leading to strong market demand. Since the beginning of the 21st century, the sea cucumber aquaculture industry has experienced rapid development, with a diverse range of farming models now in place, including shallow seabed seeding, cofferdam aquaculture, pond aquaculture, land-based factory aquaculture, shallow-water cage aquaculture, and offshore suspended cage aquaculture.

[0003] Cage farming at sea is the primary method for cultivating sea cucumbers. Its multi-layered cages offer high yields and are showing promising development prospects. However, this model still faces the following challenges. First, the farming platform essentially consists of a traditional wooden frame with bamboo poles placed within it for suspending the cages. These cages, developed from abalone cages, are primarily fed with baits such as kelp and minced fish. The cages must be lifted out of the water for manual feeding, requiring repeated cycles of "lifting the cage, opening the cage, feeding the fish, sealing the cage, and releasing the fish." This is labor-intensive and inefficient. Second, the drawbacks of traditional feeds such as kelp and minced fish are becoming increasingly apparent, and industrially produced compound feeds are becoming the future direction of development. However, because the farming model has long relied on feeding powdered and sticky feeds, the development of large-scale aquaculture equipment has been limited and lagged behind. Third, existing fish rafts are primarily constructed of wooden planks, bamboo poles, and floating barrels. These small structural units have weak load-bearing capacity and limited independence. They cannot accommodate mechanized feeding facilities, making mechanized, automated, and quantitative feeding impossible. Furthermore, the existing fish cages lack rational planning and are deployed over large areas, leading to a chaotic layout of aquaculture areas. Current aquaculture cages and rafts are no longer suitable for feeding industrialized feeds, and lack high-end design and rational functional zoning, failing to keep pace with the development of modern fisheries.

The floating platform 1 can be suspended on the sea surface. The floating platform 1 includes a central support 4, multiple annular supports 5, multiple radial supports 6, multiple suspension supports 7 and an anchoring system 9. One end of the radial support 6 is fixedly connected to the central support 4, and the other end is fixedly connected to the anchoring system 9 fixed to the seabed. Each annular support 5 is arranged in sequence from the inside to the outside with the central support 4 as the center and is fixedly connected to the radial support 6. One end of the suspension support 7 is fixedly connected to the outermost annular support 5, and the other end is fixedly connected to the anchoring system 9 fixed to the seabed. It is fixedly connected to the innermost annular bracket 5, and multiple cages 3 are fixed on each hanging bracket 7; the feeding device 2 includes a feeding boat 11 and a distributor 12, the feeding boat 11 is connected to one end of the distributor 12 and can transport bait to the distributor 12, the other end of the distributor 12 is rotatably connected to the central bracket 4, the distributor 12 makes a circular motion with the central bracket 4 as the center, and the distributor 12 is provided with multiple distribution ports. When the distributor 12 moves to directly above a hanging bracket 7, the feed port of a cage 3 is opposite to a distribution port. The central support 4, the annular support 5 and the radial support 6 form a stable suspended culture platform. The suspended culture platform is provided with multiple hanging cages 3 through the hanging support 7 for vertical culture, which not only significantly improves the culture capacity of the unit sea area, but also creates an oxygen-rich, healthy growth environment with live water for marine delicacies. The suspended culture platform cooperates with the rotatable feeder 12 to realize accurate feeding of bait. When the feeder 12 rotates with the central support 4 as the center of the circle, its feed distribution port and the feed port of the hanging cage 3 on the hanging support 7 are automatically and accurately aligned. Combined with the feeding boat 11 to supply bait, automatic and mechanized feeding is realized, which changes the traditional feeding method of sea cucumbers in the hanging cage 3. The method not only improves the feeding efficiency but also reduces the labor cost. It is suitable for the mechanized feeding of industrial pellet feed, greatly reduces the labor intensity and has high work efficiency. The mobile feeding boat 11 is maneuverable and flexible and can be used for bait transportation, storage and feeding, reducing the labor intensity of repeated loading and unloading of bait. When the weather is bad, it is convenient to return to the port to avoid, reducing the risk of bait loss. At the same time, the layout of the annular bracket 5 makes the cages 3 evenly distributed, and the overall structure has strong wind and wave resistance, which is suitable for the cultivation of marine treasures in deep waters, and is conducive to the expansion of sea cucumber cultivation areas to the open sea and the distant sea, realizing efficient and automated large-scale marine treasure cultivation. Further preferably, the multiple cages 3 on the hanging bracket 7 are arranged in layers to realize three-dimensional vertical cultivation, ensuring the smooth exchange of each layer of water and the ocean current, and creating a healthy growth environment of oxygen-rich and living water for marine treasures.

[0034] It is further preferred in the implementation manner of this embodiment that the bait feeding device 2 also includes a traction device 10 and a control system. The traction device 10 includes a track, a traction trolley and a drive assembly. The track is fixedly connected to the outermost annular bracket 5. The traction trolley can move along the track under the drive of the drive assembly. The drive assembly is connected to the control system signal. The bait feeding boat 11 includes a hull, a storage bin, an intelligent feeder and a power unit. The storage bin is fixed on the hull for carrying bait. The storage bin is connected to the distributor 12 through the intelligent feeder. The intelligent feeder can deliver a certain amount of bait to the distributor 12. The power unit is used to drive the hull to move. The intelligent feeder and the power unit are both connected to the control system signal. Through the coordinated operation of the track traction system and intelligent control, the traction trolley moves along the track fixed to the annular bracket 5 to drive the feeding boat 11 to be precisely positioned. Combined with the control system, the intelligent feeding machine quantitatively delivers bait and the power device drives the movement of the hull to achieve the precise synchronization of the bait delivery path and the rotation of the distributor 12, thereby efficiently completing the automated quantitative feeding of multiple cages 3 and significantly improving the feeding accuracy and operating efficiency.

[0035] In the embodiment of this embodiment, a buffer and a sliding device 14 slidably connected to the track are further preferably provided on the side of the hull near the annular bracket 5. Preferably, the buffer is an anti-collision wheel, which can reduce the friction between the hull and the annular bracket 5, protect the hull, and reduce the resistance of the hull when it moves forward.

[0036] It is further preferred in the implementation manner of this embodiment that the intelligent feeding machine includes a bait bin, a weighing sensor, a fan and a feed pipe, the bait bin is connected and communicated with the storage bin, and a first valve is arranged between the bait bin and the storage bin, a weighing sensor is arranged in the bait bin, the bait bin is connected and communicated with the feed pipe, and a second valve is arranged between the bait bin and the feed pipe, one end of the feed pipe is connected and communicated with the distributor 12, and the other end is connected to the fan, the first valve, the second valve, the weighing sensor and the fan are all connected to the control system signal, the distributor 12 includes a main pipeline and a plurality of branch pipelines connected and communicated with the main pipeline, one end of the main pipeline is connected and communicated with the feed pipe through a flexible joint, and the other end is connected to the collection bin, a third valve is arranged between the main pipeline and the collection bin, an electric three-way valve 13 is arranged between each branch pipeline and the main pipeline, and a feed distribution port is opened at one end of the branch pipeline away from the main pipeline, each electric three-way valve 13 and the third valve are connected to the control system signal, and each electric three-way valve 13 can be independently controlled by the control system. The weighing sensor in the bait bin can ensure that the weight of the bait entering the bait bin is constant each time. When the bait feeding operation is not in progress, each branch pipe is not connected to the main pipe. During the bait feeding operation, along the direction from the central bracket 4 to the peripheral bracket, the control system adjusts each electric three-way valve 13 in sequence, so that each branch pipe is connected to the main pipe in sequence, and ensures that only one branch pipe is connected to the main pipe, that is, when the previous branch pipe connected to the main pipe is closed, the next branch pipe can be connected to the main pipe. When the branch pipe is connected to the main pipe, the fan is turned on to blow the bait in the feed pipe to the hanging cage 3 corresponding to the branch pipe connected to the main pipe, so as to realize the quantitative delivery of bait to each hanging cage 3 and accurately control the amount of bait fed to each hanging cage 3. The collection bin at the end of the main pipe can collect the remaining bait to reduce waste.

[0037] It is further preferred in the implementation of this embodiment that the distributor 12 also includes a positioning device, the positioning device includes an electromagnet and a plurality of positioning magnets, each positioning magnet is fixed just above the connection position of each suspension bracket 7 and the annular bracket 5, the electromagnet is fixed to one end of the main pipeline close to the annular bracket 5, the electromagnet and the positioning magnet can be magnetically connected, the electromagnet is electrically connected to the control system, and the control system can control the electromagnet to be powered on or off.

[0038] In this embodiment, the innermost annular support 5 is preferably 4 to 8 meters from the edge of the central support 4, and the distance between adjacent annular supports 5 is 4 to 8 meters. The number of radial supports 6 is 4 to 8, and the radial supports 6 are evenly distributed along the circumference of the central support 4. All suspension supports 7 are evenly distributed radially along the circumference of the central support 4 in the area between the radial supports 6. The track is a circular track, fixedly connected to the outermost annular support 5, and each positioning magnet is fixed directly above the connection point between each suspension support 7 and the outermost annular support 5. Preferably, the annular supports 5 are hollow, sealed high-density polyethylene tubes with a diameter of 30 cm. The outermost annular support 5 is a double tube in parallel to increase support. A pedal is installed above the double tubes to facilitate personnel movement, and a track is installed between the pedals. The radial supports 6 are rigid structures. The annular supports 5 are fixedly connected to the suspension supports 7 by ropes. The suspension supports 7 are made of HDPE tubes with a diameter of 5 cm. The structural support of the annular supports 5 is stable and highly resistant to wind and waves, making them suitable for aquaculture in shallow and deep waters. All the suspension brackets 7 are evenly distributed radially along the circumferential direction of the central bracket 4. Therefore, the spacing between two adjacent suspension brackets 7 gradually increases as they move away from the central bracket 4. In order to make full use of the breeding area and improve the breeding yield, a connecting bracket 8 can be added between two adjacent suspension brackets 7 with a larger spacing. One end of the connecting bracket 8 is fixedly connected to the outermost annular bracket 5, and the other end is fixedly connected to the middle annular bracket 5. When the spacing between the two adjacent suspension brackets 7 meets the breeding spacing of three cages 3, the cages 3 are fixed at intervals on the connecting bracket 8.

[0039] In the embodiment of the present invention, it is further preferred that the hanging cage 3 includes a feed pipe and a cage body, the feed pipe is fixedly mounted on the suspension bracket 7, the feed opening of the feed pipe is funnel-shaped, and the discharge opening of the feed pipe is fixedly connected to the cage body. The funnel-shaped feed opening facilitates the entry of bait and prevents the bait from splashing during its fall.

[0040] Example 2

[0041] This embodiment provides a feeding method for the large-scale suspended aquaculture platform of shallow-water seafood of embodiment 1, and the steps are as follows:

[0042] Step 1: Number each suspension bracket 7 and the positioning magnet corresponding to each suspension bracket 7 in the control system, and number each cage 3 on each suspension bracket 7 along the direction from the central bracket 4 to the annular bracket 5;

[0043] Step 2: Connect the bait-casting boat 11 to the distributor 12. The control system controls the drive assembly to drive the traction trolley to move the distributor 12 and the bait-casting boat 11 in a circular motion. At the same time, the electromagnet is energized. When the electromagnet is magnetically connected to a positioning magnetic sheet, the control system controls the drive assembly to stop the traction trolley. At this time, the main pipe of the distributor 12 is located directly above a suspension bracket 7.

[0044] Step three, the control system controls the first valve to open and the second valve to close, and part of the bait in the storage bin enters the bait bin. When the weighing sensor detects that the weight of the bait in the bait bin reaches a preset value, the control system controls the first valve to close and the second valve to open, and the bait in the bait bin enters the feed pipe. Then the control system adjusts the electric three-way valve 13 near the central bracket 4 so that the branch pipe of the electric three-way valve 13 is connected to the main pipe. The third valve is closed, and then the fan is turned on to blow the feed in the feed pipe to the hanging cage 3 corresponding to the branch pipe. Then the fan is turned off and the electric three-way valve 13 near the central bracket 4 is adjusted so that the branch pipe of the electric three-way valve 13 is not connected to the main pipe.

[0045] Step 4: The control system adjusts each electric three-way valve 13 in sequence along the direction from the central support 4 to the annular support 5, so that each branch pipe is connected to the main pipe in sequence, and controls the opening and closing of the fan according to the connection status of the branch pipe and the main pipe until all the cages 3 on one suspension support 7 are fed;

[0046] Step 5: The control system then cuts off the power to the electromagnet, and controls the drive assembly to drive the traction trolley to drive the distributor 12 and the bait casting boat 11 to continue to make circular motions. When the electromagnet is a certain distance away from the previous positioning magnet, the electromagnet is energized again, so that the electromagnet is magnetically connected to the next positioning magnet. The control system controls the drive assembly to stop the traction trolley from moving. At this time, the main pipe of the distributor 12 is located directly above the next suspension bracket 7.

[0047] Step 6: Repeat steps 3 to 5 until all the cages 3 on the entire breeding platform are fed.

[0048] The control system can automatically form a feeding control plan based on the layout of the cages 3 on a suspension bracket 7, and a certain amount of bait is sequentially fed into the main pipeline of the distributor 12 at certain intervals. The control system controls the electric three-way valve 13 to open in sequence, and the bait is fed into the feed port and falls into the interior of the cage 3 through the feed pipe. After the feeding is completed, the fan is turned on to blow the remaining bait in the main pipeline into the collection bin. After the feeding of a row of cages 3 on each suspension bracket 7 is completed, the control system starts the tractor, which pulls the hull and distributor 12 to rotate along the central bracket 4. When the energized electromagnet on the main pipeline moves and senses the next positioning magnet, the tractor stops moving and the intelligent feeding machine starts feeding. This cycle can automatically complete the feeding of all cages 3 on the entire aquaculture platform. The large-scale suspended aquaculture platform for shallow-water marine treasures has realized automated and mechanized feeding, changing the traditional cage 3 aquaculture feeding method for seafood, greatly saving manpower and material costs.

The large suspended aquaculture platform for shallow-water marine products according to claim 7, characterized in that: The innermost annular bracket is 4 to 8 meters away from the edge of the central bracket, the distance between adjacent annular brackets is 4 to 8 meters, the number of radial brackets is 4 to 8, and the radial brackets are evenly distributed along the circumference of the central bracket. All the suspension brackets are radially and evenly distributed in the area between the radial brackets along the circumferential direction of the central bracket. The track is a circular track, which is fixedly connected to the outermost annular bracket, and each positioning magnet is fixed directly above the connection position between each suspension bracket and the outermost annular bracket.

9. The large suspended aquaculture platform for shallow-water marine products according to claim 1, characterized in that: The hanging cage includes a feed pipe and a cage body. The feed pipe is fixedly installed on the suspension bracket. The feed port of the feed pipe is funnel-shaped, and the discharge port of the feed pipe is fixedly connected to the cage body.

10. A feeding method for a large suspended aquaculture platform for shallow-water marine delicacies according to claim 8, characterized in that: Here are the steps: Step 1: numbering each of the suspension brackets and the positioning magnets corresponding to each of the suspension brackets in the control system, and numbering each of the cages on each of the suspension brackets along the direction from the central bracket to the annular bracket; Step 2: Connect the bait-casting boat to the distributor, and the control system controls the drive assembly to drive the traction trolley to move the distributor and the bait-casting boat in a circular motion, while energizing the electromagnet. When the electromagnet is magnetically connected to one of the positioning magnetic sheets, the control system controls the drive assembly to stop the traction trolley from moving. At this time, the main pipe of the distributor is located directly above one of the suspension brackets. Step three, the control system controls the first valve to open and the second valve to close, and part of the bait in the storage bin enters the bait bin. When the weighing sensor detects that the weight of the bait in the bait bin reaches a preset value, the control system controls the first valve to close and controls the second valve to open, and the bait in the bait bin enters the feed pipe. Then the control system adjusts the electric three-way valve near the central bracket so that the branch pipe of the electric three-way valve is connected to the main pipe, the third valve is closed, and then the fan is turned on to blow the feed in the feed pipe to the hanging cage corresponding to the branch pipe. Then the fan is turned off and the electric three-way valve near the central bracket is adjusted so that the branch pipe of the electric three-way valve is not connected to the main pipe. Step 4: the control system sequentially adjusts each of the electric three-way valves along the direction from the central support to the annular support, so that each of the branch pipes is connected to the main pipe in sequence, and controls the opening and closing of the fan according to the connection status of the branch pipe and the main pipe until all the cages on one of the hanging supports are fed; Step 5: The control system then cuts off the power to the electromagnet, and controls the drive assembly to drive the traction trolley to drive the distributor and the bait casting boat to continue to move in a circular motion. When the electromagnet moves a certain distance away from the previous positioning magnet, the electromagnet is energized again, so that the electromagnet is magnetically connected to the next positioning magnetic sheet. The control system controls the drive assembly to stop the movement of the traction trolley. At this time, the main pipeline of the distributor is located directly above the next suspension bracket. Step 6: Repeat steps 3 to 5 until all the cages on the entire breeding platform are fed.
