Description

Technical Field

[0001] This application relates to the field of marine engineering technology, and more specifically, to marine engineering equipment for seaweed farm habitats. Background Technology

[0002] Traditional algae and shellfish farming primarily utilizes raft culture, which involves setting up floating rafts in shallow seas and intertidal zones, with ropes attached to the supports to suspend algae and shellfish seedlings. Raft culture makes full use of water areas and natural nutrients, resulting in low costs, high yields, and significant economic benefits. However, this method is relatively extensive, as the farming area cannot be adjusted during the growth of algae and shellfish, leading to poor quality. It is also significantly affected by natural factors such as ocean currents and weather; insufficient seawater flow or storms can cause mass mortality of algae and shellfish, and harvesting is easily affected by weather, resulting in reduced yields and severe economic losses. Furthermore, current raft culture methods require a large workforce, with workers experiencing high labor intensity and risks, leading to labor shortages in recent years.

[0003] Traditional marine fish farming mainly involves cage culture, which only cultivates one or a variety of fish species. It does not realize a multi-species ecological farming model that mixes algae and shellfish. The farming space lacks hierarchy and cannot create a seaweed bed ecological environment that fish can adapt to. Under this farming method, fish mortality and fish quality decline are likely to occur, resulting in reduced economic benefits.

[0004] Therefore, there is an urgent need for a green and ecological marine engineering equipment that is easy to operate, less affected by natural factors such as the ocean and weather, can restore the ecological environment of seaweed farms, and realize a mixed multi-species ecological aquaculture model of algae, shellfish and fish, so as to meet people's increasing demand for high-quality seafood.

The multiple gear sets are vertically distributed along the first support frame.

[0008] Preferably, each gear set includes two coaxial gears, which are symmetrically arranged on both sides of the screw lifting mechanism and are meshed with corresponding racks.

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0032] The present application will now describe a marine engineering equipment for seaweed farm habitats provided in the embodiments of this application.

[0033] Please see Figure 1 and Figure 2 The diagram below illustrates the structure of the marine engineering equipment for seaweed farm habitats. The equipment includes a main frame assembly 1 and an aquaculture raft assembly 2 housed within the main frame assembly 1. The main frame assembly 1 is a floating frame structure whose weight can be adjusted by adding or removing water. Corresponding tensioning and lifting mechanisms 3 are provided at both ends of the top of the main frame assembly 1. The aquaculture raft assembly 2 is horizontally suspended between the corresponding tensioning and lifting mechanisms 3. A net 4 is provided on the inner side of the main frame assembly 1. In this embodiment, the main frame assembly 1 is a cuboid frame structure, and the aquaculture raft assembly 2 is an oblong structure, with both ends horizontally suspended from the tensioning and lifting mechanisms 3 at the top ends of the main frame assembly 1. The raft assembly 2 moves upward or becomes tensioned as the position of the tensioning and lifting mechanisms 3 changes. Specifically, the main frame component 1 supports the other components, the aquaculture raft component 2 is used for cultivating algae and shellfish, and the netting 4 within the main frame component 1 is used for cultivating fish. This three-dimensional mixed culture of algae, shellfish, and fish creates a seaweed farm ecosystem adapted to fish, achieving a mixed multi-species ecological aquaculture model that improves the quality of seafood, fully utilizes the internal space of the main frame component 1, and yields significant economic benefits. Furthermore, the weight of the main frame component 1 can be adjusted by adding or removing water according to the growth of the seafood, thereby adjusting its draft and altering the growth environment of algae, shellfish, and fish within it, such as temperature, depth, and light intensity. The position of the main frame component 1 can also be moved according to climate and weather to improve the growth environment of the seafood, reduce adverse environmental impacts, and minimize the influence of natural factors such as the ocean and weather, thus increasing seafood yield. The netting 4 prevents the escape of farmed fish and prevents external fish and shrimp from consuming the algae and shellfish on the aquaculture raft component 2, reducing seafood yield losses.

[0034] Please see Figure 3 and Figure 4 In one embodiment, there are multiple tensioning and lifting mechanisms 3 on the same side of the top of the main frame assembly 1, and an operating position 9 is provided between adjacent tensioning and lifting mechanisms 3; specifically, in this embodiment, there are two tensioning and lifting mechanisms 3 on the same side of the top of the main frame assembly 1, and there are also two aquaculture raft assemblies 2. An operating position 9 is provided between two adjacent tensioning and lifting mechanisms 3. The operating position 9 is used to provide workers with a working space for fishing, which is convenient for operation.

[0035] Please see Figures 5 to 8Furthermore, the tensioning and lifting mechanism 3 includes a fixing mechanism 31, a screw lifting mechanism 32, a horizontal linear mechanism 33, and a rotating wheel mechanism 34. The fixing mechanism 31 is located on the inner top of the main frame assembly 1. The screw lifting mechanism 32 is vertically mounted on the fixing mechanism 31. The inner side of the fixing mechanism 31 is provided with a retractable horizontal linear mechanism 33 that is arranged along the length direction of the main frame assembly 1. The horizontal linear mechanism 33 moves up and down along the screw lifting mechanism 32. The end of the horizontal linear mechanism 33 is rotatably connected to the rotating wheel mechanism 34, which is connected to the aquaculture raft frame assembly 2. Specifically, the surface of the fixing mechanism 31 is provided with a handle, which is connected to the screw lifting mechanism 32. The screw lifting mechanism 32 is used to adjust the height of the aquaculture raft assembly 2 and lift it off the water surface. The horizontal linear mechanism 33 is used to adjust the horizontal position of the aquaculture raft assembly 2. The rotating wheel mechanism 34 is used to adjust the tension of the aquaculture raft assembly 2. The tensioning and lifting mechanism 3 realizes the tensioning, rotation and lifting of the aquaculture raft assembly 2 out of the water, which is convenient for workers to harvest algae, feed shellfish and fish, etc. It has a high degree of automation, is easy to operate, saves time and labor, and requires low labor costs.

[0036] Furthermore, the horizontal linear mechanism 33 includes a first support frame 331, multiple gear sets 332, and a gear set drive component 333. The first support frame 331 is threadedly connected to the screw lifting mechanism 32. The gear set 332 includes meshing gears and racks. The gears are rotatably connected to the first support frame 331 via a first rotating shaft. One end of the first rotating shaft is connected to the output shaft of the gear set drive component 333. The rack is slidably connected to the first support frame 331, and the end of the rack is rotatably connected to the rotating disk mechanism 34. The multiple gear sets 332 are vertically distributed along the first support frame 331. By controlling the rotation speed of the corresponding gear set drive component 333, the distance the rack in the gear set 332 moves can be adjusted. When the racks of different gear sets 332 move different distances, the rotating disk mechanism 34 rotates in the vertical direction. In this embodiment, there are two sets of gear sets 332, and both sets of gear sets 332 are rotatably connected to the rotating disk mechanism 34. When fishing operations are needed, the operator turns the handle, and the first support frame 331 moves upward along the screw lifting mechanism 32 to adjust the height of the aquaculture raft assembly 2. The operator controls the rotation speed of the corresponding gear drive component 333 so that the rack in the upper gear set 332 moves a greater distance than the lower gear set 332. The top of the rotating wheel mechanism 34 tilts downward toward the gear set 332 and the bottom tilts upward away from the gear set 332. The rotating wheel mechanism 34 rotates vertically, causing the aquaculture raft assembly 2 to be lifted upward, making it easier for the operator to carry out fishing operations at the operating position 9.

[0037] Furthermore, each gear set 332 includes two coaxial gears, which are symmetrically arranged on both sides of the screw lifting mechanism 32 and meshed with corresponding racks. By adding symmetrically arranged gears and racks, the connection points between the horizontal linear mechanism 33 and the rotating wheel mechanism 34 are increased, thereby improving the stability of the rotating wheel mechanism 34 when rotating in the vertical direction.

[0038] Furthermore, the rotating wheel mechanism 34 includes a second support frame 341, a second rotating shaft 342, a wheel 343, and a wheel drive component 344. The second support frame 341 is rotatably connected to the end of the horizontal linear mechanism 33. The second rotating shaft 342 is vertically mounted on the second support frame 341. The top of the second rotating shaft 342 is connected to the output shaft of the wheel drive component 344, and the bottom of the second rotating shaft 342 is connected to the wheel 343. The wheel 343 is connected to the aquaculture raft assembly 2. Specifically, the wheel 343 has a rope guide groove in its circumference, and is connected to the aquaculture raft assembly 2 through the rope guide groove. The wheel drive component 344 drives the second rotating shaft 342 to rotate. Under the action of the second rotating shaft 342, the wheel 343 rotates horizontally, causing the aquaculture raft assembly 2 to be tensioned.

[0039] In this embodiment, the gear drive component 333 consists of a motor and a reducer. The output shaft of the motor is connected to the first rotating shaft through the reducer, controlling the rotation of the gears, which in turn drives the rack to move, thereby controlling the position and rotation angle of the rotating wheel mechanism 34. The wheel drive component 344 consists of a motor and a reducer. The output shaft of the motor is connected to the second rotating shaft 342 through the reducer, driving the second rotating shaft 342 and the wheel 343 to rotate, thereby tensioning the aquaculture raft assembly 2.

[0040] In another embodiment, the tensioning and lifting mechanism 3 includes a hydraulic system. The gear drive component 333 is a hydraulic motor connected to the first rotating shaft, controlling the rotation of the gears, which in turn moves the rack, thereby controlling the position and rotation angle of the rotating wheel mechanism 34. The wheel drive component 344 is a hydraulic motor connected to the second rotating shaft 342, driving the second rotating shaft 342 and the wheel 343 to rotate, thereby tensioning the aquaculture raft assembly 2.

[0041] Please see Figures 1 to 3 Furthermore, multiple water-pushing impellers 5 are vertically arranged inside the main frame assembly 1. A corresponding rotary fan 6, which drives the water-pushing impellers 5 to rotate, is connected to the top of each impeller 5. The rotary fan 6 is located at the top of the main frame assembly 1. Specifically, under the action of wind, the rotary fan 6 rotates, driving the water-pushing impellers 5 to rotate. The water-pushing impellers 5 increase the water flow within the main frame assembly 1, providing a better ecological environment for the growth of algae, shellfish, and fish.

[0042] Furthermore, a protective cover 7 is provided between the impeller 5 and the net 4 to prevent algae from being drawn into the impeller 5 and causing algae loss; the protective cover 7 provides support for the net 4 to prevent the net 4 from being drawn into the impeller 5 under the influence of the water.

[0043] Furthermore, the rotary fan 6 is equipped with a power generation device, which is connected to an energy storage device 8 installed on the main frame assembly 1. Specifically, excess wind energy is converted into electrical energy and stored in the energy storage device 8. When there is no wind on the water surface, the energy storage device 8 releases the stored electrical energy, which can drive the water-pushing impeller 5 to rotate under windless conditions, providing energy for the gear set drive component 333 and the wheel drive component 344, ensuring the normal operation of the tensioning and lifting mechanism 3, which is green and environmentally friendly. The installation of the rotary fan 6 enables the entire seaweed farm habitat marine engineering equipment to achieve zero carbon emissions.

[0044] Furthermore, the rotary fan 6 is equipped with a maximum speed protection structure that limits the rotational speed of the rotary fan 6 to prevent damage to the rotary fan 6 under extreme weather conditions.

[0045] Please see Figure 7 This is a schematic diagram of the tensioning and lifting mechanism 3 when the aquaculture raft assembly 2 is in water. Further, the aquaculture raft assembly 2 includes a growth base rope 21, multiple buoyancy generators 22, and shellfish culture containers 23. The growth base rope 21 is horizontally suspended at both ends on the rotating wheel mechanism 34 of the tensioning and lifting mechanism 3. The buoyancy generators 22 and corresponding shellfish culture containers 23 are evenly distributed on the growth base rope 21 via ropes. The aquaculture raft assembly 2 is connected to anchor ropes for fixing its position. The buoyancy generators 22 are hollow structures that provide buoyancy to the aquaculture raft assembly 2. The shellfish culture containers 23 are three-dimensional net cage structures that provide growth space for the shellfish. Specifically, algae are suspended and grow on the growth base rope 21, with the algae and shellfish culture containers 23 spaced apart. Shellfish grow inside the shellfish culture containers 23, while fish grow inside the netting 4 of the main frame assembly 1. The algae provide sufficient dissolved oxygen and nutrients to the water, improving the aquaculture environment, increasing the growth rate and product quality of the fish, and reducing aquaculture costs.

[0046] The method of using this invention is as follows: When fishing is required, the operator turns the handle, and the first support frame 331 moves upward along the screw lifting mechanism 32; the rotation speed of the corresponding gear set drive component 333 is controlled so that the rack in the upper gear set 332 moves a greater distance than the lower gear set 332, and the rotating wheel mechanism 34 rotates in the vertical direction, driving the aquaculture raft frame assembly 2 to lift upward; the wheel drive component 344 is activated to drive the wheel 343 to rotate horizontally, so that the aquaculture raft frame assembly 2 is tensioned.

[0047] In this invention, 1. the invention provides marine engineering equipment for seaweed farm habitat, including a main frame component 1 and an aquaculture raft component 2 disposed inside the main frame component 1. The inner side of the main frame component 1 is provided with a net 4. The aquaculture raft component 2 is used for cultivating algae and shellfish, and the net 4 of the main frame component 1 is used for cultivating fish. Through the three-dimensional polyculture of algae, shellfish and fish, a seaweed farm ecological environment adapted to fish is constructed, realizing a mixed multi-species ecological aquaculture mode of algae, shellfish and fish, improving the quality of seafood, making full use of the internal space of the main frame component 1, and achieving significant economic benefits.

[0048] 2. The main frame component 1 is a floating frame structure whose weight can be adjusted by filling or draining water. The weight of the main frame component 1 can be adjusted according to the growth of seafood, thereby adjusting the draft of the main frame component 1 and thus changing the growth environment of algae, shellfish and fish inside the main frame component 1, such as temperature, depth and light intensity. The position of the main frame component 1 can also be moved according to climate and weather to improve the growth environment of seafood, reduce the adverse effects of the environment, and be less affected by natural factors such as the ocean and weather, thereby increasing the yield of seafood.

[0049] 3. The main frame component 1 is equipped with corresponding tensioning and lifting mechanisms 3 at both ends of the top. The aquaculture raft component 2 is horizontally suspended between the corresponding tensioning and lifting mechanisms 3. The tensioning and lifting mechanisms 3 are used to tension, rotate and lift the aquaculture raft component 2 out of the water, which makes it convenient for staff to harvest algae, feed shellfish and fish, etc. It has a high degree of automation, is easy to operate, saves time and labor, and has low labor costs.

[0050] 4. The netting 4 prevents the fish inside from escaping and prevents external fish and shrimp from eating the algae and shellfish on the aquaculture raft assembly 2, thus reducing the loss of seafood production.

[0051] 5. The protective cover 7 prevents algae from being drawn into the impeller 5 and causing algae loss; it also provides support for the net 4 and prevents the net 4 from being drawn into the impeller 5 by the water.

[0052] 6. The water impeller 5 increases the water flow within the main frame component 1, providing a better ecological environment for the growth of algae, shellfish and fish.

[0053] 7. The rotating fan 6 is equipped with a power generation device. When there is wind, it stores excess wind energy as electrical energy. When there is no wind, it releases the electrical energy stored in the energy storage device 8. Under windless conditions, it can drive the water-pushing impeller 5 to rotate, providing energy for the gear set drive component 333 and the wheel drive component 344, ensuring the normal operation of the tensioning and lifting mechanism 3. It is green and environmentally friendly. The installation of the rotating fan 6 enables the entire seaweed farm habitat marine engineering equipment to achieve zero carbon emissions.
