Description

Technical Field

[0001] The invention relates to a combined biological floating bed suitable for saline-alkali water aquaculture ponds, belonging to the technical field of aquaculture. Background Art

[0002] Existing saline-alkali aquaculture ponds face numerous challenges. For example, leftover bait and feces generated during the aquaculture process can cause the accumulation of harmful substances such as ammonia nitrogen and nitrite in the pond water, leading to deterioration of water quality. This, in turn, affects the growth and health of the aquaculture organisms, restricting both production and economic benefits. Therefore, water purification devices are needed to reduce eutrophication and improve pond water quality. However, existing water purification devices suffer from complex structures, low efficiency, and susceptibility to extreme environmental influences.

[0003] For example, patent publication number CN214457101U, published on October 22, 2021, discloses a combined biofloating bed suitable for saline-alkali aquaculture ponds. The biofloating bed comprises a foam float, to which are fixed solar panels, a water pump, and a reactor. The reactor is a transparent open container, which is a composite structure of a cone and a cylinder, with an upper cylindrical container and a lower conical container. The lower end of the cone is open and connected to a drain pipe, which extends beyond the foam float. The reactor limits the number of aquatic plants that can be planted, affecting the efficiency of the biofloating bed. Furthermore, the biofloating bed has low wind and wave resistance and is susceptible to extreme weather conditions, causing partial structural failure or damage.

[0004] In view of the shortcomings of the above-mentioned prior art, a combined biological floating bed is designed to overcome the shortcomings of the prior art, increase the number of aquatic plants planted to improve the water quality of the pond, and adjust the positions of adjacent floats to improve the working stability and efficiency of the combined biological floating bed. Summary of the Invention

[0005] In order to overcome the shortcomings of the above-mentioned prior art, such as the limited number of aquatic plants that can be planted in the biological floating bed, which affects the working efficiency of the biological floating bed, and the biological floating bed has low wind and wave resistance and is easily affected by extreme weather environments, the present application provides a combined biological floating bed suitable for saline-alkali water aquaculture ponds to improve the pond water quality and enhance the working stability and efficiency of the combined biological floating bed.

[0006] The combined biological floating bed provided in the embodiment of the present application includes a bed body, a bed frame and an adjustment mechanism. The bed body includes multiple float plate assemblies. The bed frame is arranged around the periphery of the bed body. The adjustment mechanism is arranged between the bed body and the bed frame. The bed body and the bed frame are connected by the adjustment mechanism. Adjacent float plate assemblies are connected by the adjustment mechanism. The adjustment mechanism is used to drive adjacent float plate assemblies to move in a direction of approaching or moving away from each other.

[0007] In the embodiments of the present application, the combined biofloating bed comprises multiple float assemblies, each of which can be planted with a variety of aquatic plants capable of absorbing nutrients such as nitrogen and phosphorus, as well as harmful substances, from the water. This reduces eutrophication in the pond, improves water quality, and promotes the growth of aquaculture organisms. A frame surrounds the perimeter of the bed, shaping the bed above the water surface and providing effective buoyancy support. The frame's large footprint increases the surface area occupied by the combined biofloating panels, thereby increasing the overall buoyancy of the combined biofloating bed and enhancing its operational stability.

[0008] The adjusting mechanism is located between the bed body and the bed frame and can drive adjacent floating plate assemblies to move in directions closer to or away from each other. Specifically, at night or in severe weather such as strong winds, the adjusting mechanism can be controlled to drive adjacent floating plate assemblies to move in directions closer to each other, so that multiple floating plate assemblies are combined into a whole, thereby increasing the ability of the combined biological floating bed to resist wind and waves and improving the reliability of the combined biological floating bed.

[0009] When the regulating mechanism drives adjacent float plate assemblies to move in a direction away from each other, the distance between adjacent float plate assemblies increases, exposing the water surface between them. Air can enter the water through the exposed water surface, so that the roots of aquatic plants in the middle position of the combined biological floating bed can absorb more oxygen, which is convenient for the growth of aquatic plants and reduces the probability of aquatic plant roots lacking oxygen, leading to their poor development or death. Moreover, as the distance between adjacent float plate assemblies increases, the distance between aquatic plants on the float plate assemblies also increases, which can increase the light-receiving area of the aquatic plants, allowing the aquatic plants to grow more luxuriantly, thereby improving the purification effect of the combined biological floating bed and improving the working efficiency of the combined biological floating bed.

[0040] The present invention provides a combined biological floating bed 100 suitable for saline-alkali water aquaculture ponds, aiming to improve pond water quality and enhance the working stability and working efficiency of the combined biological floating bed 100.

[0041] The embodiment of the present application provides a combined biological floating bed 100 suitable for saline-alkali water aquaculture ponds, such as Figures 1 to 3 As shown, the combined biological floating bed 100 includes a bed body 1, a bed frame 2 and an adjustment mechanism 3. The bed body 1 includes a plurality of float plate assemblies 11. The bed frame 2 is arranged around the periphery of the bed body 1. The adjustment mechanism 3 is arranged between the bed body 1 and the bed frame 2. The bed body 1 and the bed frame 2 are connected by the adjustment mechanism 3. Adjacent float plate assemblies 11 are connected by the adjustment mechanism 3. The adjustment mechanism 3 is used to drive adjacent float plate assemblies 11 to move in a direction of approaching or moving away from each other.

[0042] In the embodiment of this application, Figures 1 to 3As shown, the combined biofloating bed 100 comprises a plurality of floating plate assemblies 11. Each of these assemblies 11 can be planted with a variety of aquatic plants capable of absorbing nutrients and harmful substances such as nitrogen and phosphorus from the water, thereby reducing eutrophication, improving water quality, and promoting the growth of aquatic organisms. These aquatic plants, including but not limited to reeds, Suaeda salsa, and Acorus calamus, are salt- and alkali-tolerant aquatic plants. Their roots absorb pollutants such as nitrogen and phosphorus, which they use for their own growth and metabolism. Furthermore, the salt- and alkali-tolerant microorganisms they produce decompose and transform organic matter, thereby creating a stable and efficient plant-based purification system.

[0043] Specifically, calamus, for example, contains important enzymes such as nitrate reductase, which converts absorbed nitrate nitrogen into organic nitrogen, enabling nitrogen assimilation. Simultaneously, the plant's roots secrete organic matter, which provides a necessary carbon source for microorganisms, promoting their decomposition of pollutants and synergistically improving water purification.

[0044] In the embodiment of the present application, the roots of aquatic plants planted on the floating plate assembly 11 provide an ideal attachment site and abundant nutrients for microorganisms. The inorganic nutrients produced by the microorganisms decomposing organic matter are then absorbed and utilized by the plants. In the combined biological floating bed system, different microenvironments, such as aerobic and anoxic, are formed around the plant roots. This diverse environment is suitable for the growth of microorganisms with different functions, promoting the enrichment and diversification of the microbial community, greatly enhancing the ability to degrade various pollutants, and improving the purification effect of the combined biological floating bed 100.

[0045] In the embodiment of the present application, the bed frame 2 is arranged around the periphery of the bed body 1, and can shape the bed body 1 placed on the water surface, providing effective buoyancy support for the bed body 1; the bed frame 2 has a large coverage area, which can increase the occupied area of the combined biological floating plate 110 on the water surface, thereby increasing the overall buoyancy of the combined biological floating bed 100 and improving the working stability of the combined biological floating plate 110.

[0046] In the embodiment of this application, Figure 2 As shown, the frame 2 also protects the bed 1 located within it. When the combined biological floating bed 100 moves toward the edge of the pond under the influence of wind and waves, the outer frame 2 first comes into contact with soil or rocks. This reduces the probability of impact on the bed 1 inside the frame 2, thereby reducing the probability of damage to the aquatic plants on the bed 1 and improving the reliability of the combined biological floating bed 100. Furthermore, the frame 2 and individual floating bed components can be replaced independently, reducing the difficulty and cost of maintenance of the combined biological floating bed 100.

[0047] In the embodiments of the present application, the material of the bed 1 includes, but is not limited to, chemically resistant materials such as high-density polyethylene (HDPE), volcanic rock, and polyurethane foam, or any combination of these materials. The material of the bed frame 2 includes, but is not limited to, plastic, plastics, polyvinyl chloride, or any combination of these materials. The top view of the bed 1 can be circular, in which case the bed frame 2 can be a circular tubular shape; the top view of the bed 1 can be rectangular, in which case the bed frame 2 can be a square tubular shape. The shapes and materials of the bed 1 and bed frame 2 can be customized according to actual needs and are not limited in this application, so as to further enhance the applicability of the combined biological floating bed 100.

[0048] In the embodiment of this application, Figure 2 As shown, the adjustment mechanism 3 is located between the bed 1 and the bed frame 2 and is capable of driving adjacent float assemblies 11 toward or away from each other. Specifically, at night or in severe weather such as strong winds, the adjustment mechanism 3 can be controlled to drive adjacent float assemblies 11 toward each other, gradually reducing the spacing between adjacent float assemblies 11 until it reaches zero. At this point, the multiple float assemblies 11 are integrated into a single unit, which can enhance the combined biological floating bed 100's ability to withstand wind and waves and improve its reliability. Furthermore, the integration of the multiple float assemblies 11 into a single unit can also reduce the probability of root damage to aquatic plants during wind and wave attacks, thereby increasing the lifespan of the aquatic plants and enhancing the reliability of the combined biological floating bed 100.

[0049] In the embodiment of the present application, when the adjustment mechanism 3 drives the adjacent float plate assemblies 11 to move in a direction away from each other, the distance between the adjacent float plate assemblies 11 is enlarged to expose the water surface, and air can enter the underwater through the exposed water surface, so that the roots of aquatic plants in the middle position of the combined biological floating bed 100 can absorb more oxygen, which is convenient for the growth of aquatic plants and reduces the probability of aquatic plant roots lacking oxygen and causing their poor development or death; and the distance between adjacent float plate assemblies 11 is enlarged, so that the distance between the aquatic plants located on the float plate assemblies 11 is also increased, thereby increasing the light-receiving area of the aquatic plants, so that the aquatic plants can grow more luxuriantly, thereby improving the purification effect of the combined biological floating bed 100 and improving the working efficiency of the combined biological floating bed 100.

[0050] In the embodiment of the present application, the number of float assemblies 11 can be set based on actual needs such as the area of the aquaculture pond, the density of the aquacultured fish, and the duration of the aquaculture. This is not limited in this application, so as to further improve the applicability of the combined biological floating bed 100. Optionally, the combined biological floating bed 100 can be secured in a suitable position using anchor ropes and anchors. The anchor ropes can be made of high-strength, salt- and alkali-resistant ropes, and the anchors can be concrete or heavy objects to ensure the stable fixation of the bed 1 under various water flow and wind and wave conditions, thereby improving the operational stability of the combined biological floating bed 100.

[0051] In some embodiments, as Figures 1 to 3 As shown, each float assembly 11 includes at least one float 110, and each float 110 includes at least one first through hole 1101 and at least one second through hole 1102 arranged at intervals. The first through hole 1101 is used to fix aquatic plants and provide planting and growth space for aquatic plants. The second through hole 1102 can expose the water surface around the roots of aquatic plants, provide oxygen for the growth of aquatic plants, and facilitate the growth of aquatic plants. A trough can be set on one side of the first through hole 1101 located on the planting surface 12 to better provide growth space for aquatic plants and reduce the probability of aquatic plants falling. One first through hole 1101 or two can be opened on the float 110. The number of the first through hole 1101 and the second through hole 1102 can be set according to actual needs, and this application does not limit this. The first through hole 1101 and the second through hole 1102 include but are not limited to circular through holes, rectangular through holes and elliptical through holes.

[0052] In the embodiment of this application, Figure 4 As shown, the floating plate 110 may include a first through-hole 1101 located at the center and four second through-holes 1102 evenly distributed around the periphery of the first through-hole 1101. This not only ensures the effective cultivation of aquatic plants, but also reduces material consumption during the manufacture of the floating plate 110. It also ensures that the force applied to the floating plate 110 on the water surface is uniform, improving the operational stability of the floating plate assembly 11 and, consequently, the combined biological floating bed 100. The material of the floating plate 110 includes, but is not limited to, high-density polyethylene.

[0053] Preferably, each float plate assembly 11 may also include a plurality of float plates 110, and the plurality of float plates 110 extend along the second direction Y. Adjacent float plates 110 may be fixedly connected by high-strength corrosion-resistant connectors, including but not limited to connecting ropes, connecting bolts and connecting clips, to ensure that the connection between the float plates 110 is firm and can adapt to a certain degree of deformation, thereby improving the reliability and working stability of the combined biological floating bed 100.

[0054] In the embodiment of the present application, the size and dimensions of the float 110 can be set according to the growth size of the aquatic plant to be planted. For example, when the aquatic plant to be planted is Acorus calamus, the size of the float 110 for planting Acorus calamus needs to be determined based on factors such as the planting density, growth characteristics, and specific environment of the pond. Typically, the planting density of Acorus calamus is 4 to 6 plants per square meter, and each Acorus calamus occupies an area of approximately 0.17 to 0.25 square meters. Since Acorus calamus is relatively large, ranging from 60 to 150 centimeters, and its leaves are sword-shaped and linear, it requires a certain amount of space to stretch when growing. To avoid overcrowding of the plants, which affects growth and ventilation, a spacing of 30 to 50 centimeters should be maintained between adjacent plants.

[0055] Acorus can be planted individually or in groups. Considering the actual purification effect and aesthetics, it is planned to plant four Acorus on one float 110. At this time, the float 110 can be designed to be 1 to 1.2 meters long and 0.8 to 1 meter wide. This ensures that each Acorus has enough space to grow while fully utilizing the float area. If the number of plants is large, the number of floats 110 can be increased accordingly. In larger ponds, the size of the float 110 can be appropriately larger to form a larger area for planting Acorus, enhancing the landscape effect and ecological function; while in smaller ponds or areas with faster water flow, the size of the float 110 should be smaller to facilitate installation and fixation and prevent it from being washed away by the water flow. In actual applications, small-scale experiments can also be conducted to observe the growth of Acorus on floats 110 of different sizes, and then determine the most suitable float size.

[0056] In some embodiments, as Figures 1 to 3 As shown, the adjustment mechanism 3 includes an adjustment component 31 and a telescopic component 32. The adjustment components 31 are respectively arranged on opposite sides of the bed body 1; the telescopic component 32 is arranged between any adjustment component 31 and the bed frame 2, and the telescopic component 32 is used to drive the adjustment component 31 connected thereto to move in a direction close to or away from the bed frame 2.

[0057] In the embodiment of this application, Figures 1 to 3 As shown, two adjustment assemblies 31 are disposed on opposite sides of the bed 1, balancing the forces on both sides of the bed 1 and improving the operational stability of the combined biological floating bed 100. When the telescopic assembly 32 drives the adjustment assembly 31 toward the bed frame 2, the adjustment assembly 31 drives the adjacent float assemblies 11 toward each other, uniting the float assemblies 11. When the telescopic assembly 32 drives the adjustment assembly 31 away from the bed frame 2, the adjustment assembly 31 drives the adjacent float assemblies 11 away from each other, dispersing the float assemblies 11. The telescopic assembly 32 includes, but is not limited to, telescopic mechanisms such as cylinders, pneumatic push rods, hydraulic push rods, and electric push rods.

[0058] Optionally, two telescopic components 32 may be provided respectively between each adjustment component 31 and the bed frame 2 , so that the forces on both sides of the bed body 1 are balanced, thereby further improving the working stability of the combined biological floating bed 100 .

[0059] In some embodiments, as Figures 1 to 3As shown, the adjustment assembly 31 includes a guide rail 311, a first slider 312 and a first connecting rod 313. The guide rail 311 extends along a first direction X and can move linearly along a second direction Y. The first slider 312 is arranged between adjacent floating plate assemblies 11 and is slidably connected to the guide rail 311; the first slider 312 is respectively connected to the adjacent floating plate assemblies 11 through the first connecting rod 313, one end of the first connecting rod 313 is hinged to the floating plate assembly 11, and the other end is hinged to the first slider 312; the first direction X is the direction in which adjacent floating plate assemblies 11 approach or move away from each other, and the second direction Y is perpendicular to the first direction X.

[0060] In the embodiment of this application, Figures 1 to 3 As shown, the guide rail 311 is connected to telescopic components such as push rods in the telescopic assembly 32. Movement of the telescopic assembly 32 drives the guide rail 311 to linearly move in the second direction Y. When the guide rail 311 approaches the floating plate assembly 11 in the second direction Y, it drives the second slider 34 to move toward the floating plate assembly 11. The two first connecting rods 313 located between the second slider 34 and the adjacent floating plate assembly 11 are compressed, causing the hinged ends of the two first connecting rods 313 to move away from each other, thereby driving the adjacent floating plate assemblies 11 to move away from each other and controlling the separation of the floating plate assemblies 11. Furthermore, when the guide rail 311 moves away from the floating plate assembly 11 in the second direction Y, it drives the second slider 34 to move away from the floating plate assembly 11. The second slider 34 drives the two first connecting rods 313 to move, causing the hinged ends of the two first connecting rods 313 to move toward each other, thereby driving the adjacent floating plate assemblies 11 to move toward each other and controlling the closing of the floating plate assemblies 11. The regulating assembly 31 has a simple structure and low manufacturing, installation and maintenance costs, which can greatly reduce the application cost of the combined biological floating bed 100.

[0061] In some embodiments, as Figures 5 to 7 As shown, the combined biological floating bed 100 also includes an adjustment mechanism 4, which includes a plurality of adjustment components 41 evenly arranged on the periphery of the bed frame 2. The adjustment component 41 includes an inflation / exhaust component 411, a float 412 and a float plate 413. The inflation / exhaust component 411 is connected to the float 412 and is used to inflate or exhaust the float 412. The float 412 extends along the third direction Z; the float plate 413 includes a first part 4131 and a second part 4132 that are fixedly connected. The first part 4131 is at least partially placed in the float 412. Along the third direction Z, the projected area of the second part 4132 is larger than the projected area of the first part 4131; the bed body 1 includes a planting surface 12 for planting plants. The float plate 413 is located on the side of the bed body 1 away from the planting surface 12, that is, the float plate 413 is at least partially placed under the water surface, and the third direction Z is perpendicular to the water surface.

[0062] In the embodiment of this application, Figures 1 to 3As shown, multiple adjustment components 41 are evenly arranged around the perimeter of the frame 2, ensuring uniform force on the combined biological floating bed 100 on the water surface and improving its operational stability. The inflation and exhaust components 411 can inflate and exhaust the buoyancy chamber 412, thereby controlling the depth of the first portion 4131 of the float 413 within the buoyancy chamber 412 and the position of the float 413 in the water. This, in turn, changes the buoyancy provided by the float 413, thereby adjusting the orientation and position of the combined biological floating bed 100 to accommodate a variety of environmental changes. The inflation and exhaust components 411 include, but are not limited to, an air pump and an exhaust valve.

[0063] Specifically, the venting member 411 vents the buoy 412, controlling the placement of most, or even all, of the first portion 4131 of the float 413 within the buoy 412. This causes the combined biological floating bed 100 to sink deeper into the water, reducing the buoyancy provided by the float 413. This increases the stability of the combined biological floating bed 100 and allows it to cope with severe weather conditions such as strong winds. The venting member 411 inflates the buoy 412, reducing the placement of the first portion 4131 of the float 413 within the buoy 412 and increasing the buoyancy provided by the float 413. This allows the bottom of the bed 1 of the combined biological floating bed 100 to emerge from the water, allowing the roots of aquatic plants to come into contact with air, allowing them to better absorb oxygen and perform photosynthesis, thereby enhancing the purification effect.

[0064] In the embodiment of the present application, the orientation of the combined biological floating bed 100 can be controlled by controlling the depth of the first part 4131 of the floating plate 413 at different positions within the buoy 412, so that the planting surface 12 of the bed body 1 forms a certain angle with the water surface, so that the aquatic plants can receive more light, improve their photosynthesis ability, and further improve the purification effect of the combined biological floating bed 100.

[0065] In the embodiment of this application, Figure 7 As shown, the first portion 4131 and the second portion 4132 of the float 413 can be integrally formed. Along the third direction Z, the projected area of the second portion 4132 is larger than that of the first portion 4131. This larger area of the second portion 4132 increases the buoyancy of the float 413 in water, better supporting the bed 1 and bed frame 2. A seal is provided at the connection between the buoy 412 and the float 413 to ensure a tight seal within the buoy 412 and proper inflation and deflation. The seal includes, but is not limited to, a sealing ring and a gasket.

[0066] In some embodiments, as Figures 1 to 3As shown, the adjustment mechanism 3 also includes a slidably connected fixed plate 33 and a second slider 34. The fixed plate 33 and the second slider 34 are disposed at both ends of the guide rail 311. The fixed plate 33 is fixedly connected to the bed frame 2, and the second slider 34 is fixedly connected to the guide rail 311. The fixed plate 33 may have a track or a slot for slidably connecting with the first slider 312. The fixed plate 33 and the second slider 34 can improve the stability of the guide rail 311 along the second direction Y, thereby improving the operating stability of the adjustment mechanism 3 and the combined biological floating bed 100.

[0067] In some embodiments, as Figures 1 to 3 As shown, the combined biological floating bed 100 further includes an energy supply mechanism 5, which is located on the side of the bed frame 2 facing away from the water surface; the energy supply mechanism 5 includes a solar panel 51, a rotating plate 52 and a battery 53, and the light absorbing surface 511 of the solar panel 51 faces the planting surface 12, as shown in FIG. Figure 8 As shown, the solar panel 51 is connected to the bed frame 2 through a rotating plate 52 . The solar panel 51 is configured to rotate around the bed frame 2 . The solar panel 51 is electrically connected to a battery 53 .

[0068] In the embodiment of the present application, the solar panel 51 and the battery 53 can convert light energy into electrical energy, thereby controlling the movement of the telescopic assembly 32, the inflation and exhaust components 411, and other components, thereby saving energy and reducing the application cost of the combined biological floating bed 100. The solar panel 51 can rotate around the bed frame 2 to adjust its angle to adapt to a more suitable lighting angle. The angle can also be adjusted in real time based on time and the initial angle to maximize the photoelectric conversion effect of the solar panel 51.

[0069] In some embodiments, the energy supply mechanism 5 further includes a wireless connector electrically connected to the battery 53, a control device, and a controller. The wireless connector and control device can transmit data related to the combined biological floating bed 100 to a remote location for monitoring and control. The wireless connection can utilize a Bluetooth or Wi-Fi module. The controller can control the opening, closing, and on / off duration of the multiple inflatable and exhaust components 411 based on remote commands or preset data.

[0070] In some embodiments, as Figure 2 and Figure 5 As shown, the energy supply mechanism 5 and the adjustment assembly 31 are arranged on two adjacent sides of the bed frame 2. The energy supply mechanism 5 also includes a second connecting rod 54. One end of the second connecting rod 54 is rotatably connected to the side of the solar panel 51 away from the bed frame 2, and the other end is rotatably connected to the second slider 34.

[0071] In the embodiment of this application, Figure 5 、 Figure 9 and Figure 10As shown, the second connecting rod 54 is rotatably connected to the solar panel 51 via a first connecting member 541. When the energy supply mechanism 5 and the adjustment assembly 31 are positioned adjacent to each other, the second slider 34 provided at the end of the guide rail 311 near the solar panel 51 can be replaced with a second connecting member 542 to facilitate connection of the second connecting rod 54. By connecting the solar panel 51 and the second slider 34 via the second connecting rod 54, the telescopic assembly 32 can simultaneously drive the solar panel 51 to produce a corresponding angular change when driving the floating plate assembly 11 toward or away from each other, thereby reducing energy consumption and lowering the application cost of the combined biological floating bed 100.

[0072] Specifically, such as Figures 2 to 5 As shown, when the telescopic assembly 32 drives the guide rail 311 in the adjustment assembly 31 to move in a direction closer to the floating plate assembly 11, it simultaneously drives the second slider 34 to move in a direction closer to the solar panel 51. The second slider 34 squeezes the second connecting rod 54, thereby driving the solar panel 51 at the other end of the second connecting rod 54 to rotate and lift, thereby adjusting the angle of the solar panel 51. When the spacing between adjacent floating plate assemblies 11 is the largest, the solar panel 51 reaches the maximum lifting height. When the telescopic assembly 32 drives the guide rail 311 in the adjustment assembly 31 to move in a direction away from the floating plate assembly 11, it simultaneously drives the second slider 34 to move in a direction away from the solar panel 51. The second slider 34 drives the second connecting rod 54 to move, thereby driving the solar panel 51 to rotate and descend, reducing the angle between the solar panel 51 and the water surface, thereby adjusting the angle of the solar panel 51.

[0073] In this embodiment of the present application, during severe weather such as strong winds or at night, the telescopic assembly 32 can be controlled to drive the bed 1 to close, thereby reducing the impact of wind and waves on the combined biological floating bed 100. During the closing process of the bed 1, the solar panel 51 is simultaneously driven to rotate, reducing the angle between the solar panel 51 and the water surface. This further reduces the impact of wind directly facing the light-absorbing surface 511 of the solar panel 51 on the combined biological floating bed 100, thereby improving the operating stability of the combined biological floating bed 100.

[0074] In some embodiments, the controller can also detect the photoelectric conversion state of the solar panel 51 through sensors and electrical signal data to control the working state of the telescopic component 32, thereby adjusting the angle of the solar panel 51 and improving power generation efficiency.

[0075] In some embodiments, as Figure 2 、 Figure 11 and Figure 12As shown, the combined biological floating bed 100 also includes a purification mechanism 6, which includes a water inlet component 61 and a purification tank 62. The purification tank 62 is located on the side of the bed frame 2 away from the water surface. Along the extension direction of the purification tank 62, the purification tank 62 includes a first side surface 621 and a second side surface 622 arranged opposite to each other; along the third direction Z, the distance between the first side surface 621 and the water surface is greater than the distance between the second side surface 622 and the water surface; the water inlet component 61 is arranged on the first side surface 621, and the water flows into the purification tank 62 through the water inlet component 61; along the direction from the first side surface 621 to the second side surface 622, the purification tank 62 is sequentially provided with a first purification layer 623, a second purification layer 624 and a third purification layer 625; the second side surface 622 includes at least one third through hole 626, and the third direction Z is perpendicular to the water surface.

[0076] In the embodiment of this application, Figure 11 and Figure 12 As shown, the water inlet assembly 61 includes a submersible pump 611 and a pipe 612. The submersible pump 611 is used to extract water from the pond into the purification tank 62 for purification. The water inlet 613 of the pipe 612 is placed above the purification tank 62, and along the third direction Z, the projection of the water inlet 613 is located within the projection of the purification tank 62. Along the third direction Z, the distance between the first side 621 and the water surface is greater than the distance between the second side 622 and the water surface. In other words, the purification tank 62 is arranged at an angle, and the height of the water inlet end of the purification tank 62 is higher than the water outlet end. This allows water to flow through the first purification layer 623, the second purification layer 624, and the third purification layer 625 in sequence under the action of gravity for purification. This eliminates the need for an additional water flow drive device, further reducing the application cost of the combined biological floating bed 100 while ensuring the purification effect.

[0077] In this embodiment, purified water flows back into the pond through the third through-holes 626, creating a localized water circulation within the pond. This promotes sufficient contact between the water and the combined biological floating bed 100, improving water purification efficiency. Furthermore, this water circulation prevents water stagnation around the combined biological floating bed 100, thus avoiding the formation of dead zones. The shapes of the third through-holes 626 include, but are not limited to, circular, rectangular, and strip-shaped.

[0078] In the embodiment of the present application, a single purification layer or multiple purification layers may be provided in the purification tank 62. The layers may be provided according to actual needs, and the present application does not limit this. The materials of the multiple purification layers may be the same or different. When the materials of the multiple purification layers are different, a purification combination may be constructed in the purification tank 62 to further reduce the nitrogen, phosphorus and salinity in the aquaculture water and improve the purification effect. The materials of the first purification layer 623 include but are not limited to zeolite, activated carbon, weathered coal, ceramic rings, quartz sand and combinations thereof; the materials of the second purification layer 624 include but are not limited to zeolite, activated carbon, weathered coal, ceramic rings, quartz sand and combinations thereof; the materials of the third purification layer 625 include but are not limited to zeolite, activated carbon, weathered coal, ceramic rings, quartz sand and combinations thereof.

[0079] Optionally, the speed and operating time of the submersible pump 611 can be adjusted based on the size and depth of the aquaculture pond, as well as the species and density of the aquaculture organisms, to control the water flow rate. The water flow rate and direction can also be regularly monitored to ensure that the water circulation is uniform and reasonable, meeting the living habits of the aquaculture organisms and the purification needs of the floating bed system.

[0080] In some embodiments, as Figure 12 As shown, the first side surface 621 is spaced apart from the first purification layer 623, and a filter layer 627 is disposed between the first side surface 621 and the first purification layer 623. The first side surface 621 and the first purification layer 623 are spaced apart to allow water to enter the purification layer through the gap. The filter layer 627 can perform preliminary filtration on the water entering the purification tank 62, reducing the probability of large particles of impurities entering the first purification layer 623 and causing blockage, thereby improving the purification effect.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
