Description

Technical Field

[0001] The present invention relates to the technical field of offshore aquaculture equipment, and more particularly to deep-sea aquaculture equipment. Background Art

[0002] At present, marine aquaculture mostly adopts the traditional nearshore aquaculture model, but nearshore aquaculture has the following problems: limited space and easy to be affected by pollution and disease; artificial feeding, monitoring and maintenance costs are high and are greatly affected by the weather; lack of accurate data support, reliance on experience and judgment, making it difficult to achieve scientific and refined aquaculture management.

[0003] As global demand for marine resource development increases, traditional aquaculture models are no longer able to meet these needs, and deep-sea aquaculture has become an important development direction. However, the deep-sea environment is complex and the weather is unpredictable. Traditional offshore aquaculture equipment has low wind and wave resistance and is difficult to adapt to the harsh and unpredictable weather conditions of the deep sea. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the existing offshore aquaculture equipment in terms of low wind and wave resistance, and to provide a deep-sea aquaculture equipment with better wind and wave resistance.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] Provided is a deep-sea aquaculture equipment, comprising aquaculture equipment and a buoyancy buffer device, the buoyancy buffer device comprising a buffer frame assembly and a float, the aquaculture equipment being connected to the float via the buffer frame assembly; the buffer frame assembly comprising a space truss, a fixed frame, an elastic buffer assembly and a plurality of damping assemblies, the two sides of one end of the space truss being connected to the fixed frame along the length direction, the two sides of the other end of the space truss being connected to the two ends of the elastic buffer assembly along the length direction, the two ends of a plurality of damping assemblies being respectively connected to the two sides of the space truss along the width direction, and the plurality of damping assemblies being located between the fixed frame and the elastic buffer assembly; the elastic buffer assembly comprising an elastic assembly and a balancing buffer assembly, the two ends of the elastic assembly and the balancing buffer assembly being respectively connected to the two sides of the space truss along the width direction, and the elastic assembly being located between the damping assembly and the balancing buffer assembly.

[0007] The deep-sea aquaculture equipment of the present invention, when using the aquaculture equipment for marine aquaculture, the buoyancy buffer device floats the aquaculture equipment as a whole on the sea surface. When encountering wind and waves, the floating plate transfers the external force received to the buffer frame assembly for buffering. The buffer frame assembly dilutes the external force to avoid transmitting the external force to the aquaculture equipment, and at the same time allows the entire equipment to float stably on the sea surface, with good wind and wave resistance. The buffer frame assembly is set to be a space truss, a fixed frame, an elastic buffer assembly and several damping assemblies, and the good wind and wave resistance of the space truss is used for buffering. However, the space truss itself is rigidly connected internally, and has high sensitivity and tolerance limits. When the wind and waves are large, the space truss is easy to fall apart. Therefore, one end of the space truss is connected to the fixed frame to give the space truss a fixed shape, and the other end of the space truss is connected to the elastic buffer assembly. The elastic assembly vibrates when it is affected by wind and waves, and the balancing buffer assembly consumes the vibration. At the same time as the vibration, the damping assembly provides resistance to avoid large vibrations in the middle section of the space truss, so that the external force generated by wind and waves on the space truss tends to be stable, and then the overall structure of the space truss is restored by the elastic assembly, thereby further improving the tolerance limit of the buffer frame assembly as a whole. The entire equipment is stably floated on the sea surface using a float plate, and the external force of wind and waves is diluted by setting a buoyancy buffer device. The buoyancy buffer device utilizes the excellent wind and wave resistance of the space truss for buffering. By connecting the space truss with the fixed frame, elastic buffer component and several damping components, the overall tolerance limit of the buffer frame component is improved, preventing the external force of wind and waves from affecting the aquaculture equipment, and making the equipment as a whole have better wind and wave resistance.

[0008] Furthermore, the elastic assembly includes multiple groups of elastic members, which are distributed along the length of the space truss. The elastic members include a first elastic connecting plate, a first spring, a second spring, a third spring, and a second elastic connecting plate, each of which includes a first connecting portion, a first curved portion, and a second connecting portion, each of which is connected in sequence. The first connecting portion is connected to the space truss, and the second connecting portion is connected to the first spring or the third spring. The first spring and the third spring each have an angle with the second spring, and the first and third springs are symmetrically arranged. The multiple groups of elastic members provide a certain degree of fixation on the unfixed end of the space truss, while also allowing for multi-level adjustment when encountering wind and waves, thereby increasing the adjustment range and making the unfixed end of the space truss more stable. The spring and the space truss are connected by an elastic connecting plate, and when impacted, the elastic members deform to provide a buffer. At this time, the deformation of the first curved portion on the elastic connecting plate provides deformation and buffer space, preventing the elastic members from directly pulling on the space truss and causing large deformation of the space truss, and also preventing the elastic members from separating from the space truss.

[0009] Furthermore, the balancing buffer assembly includes a tuned mass damper and two groups of damping structures. The two ends of the tuned mass damper are respectively connected to the two groups of damping structures. The two groups of damping structures are respectively connected to the two sides of the space truss along the width direction. The tuned mass damper is arranged along the width direction of the space truss, and the two groups of damping structures are both arranged along the length direction of the space truss. By setting up the tuned mass damper, the tuned mass damper will produce a larger response due to the resonance of the wave waves. Its frequency will be tuned to be consistent with the horizontal vibration frequency of the waves, absorbing the external force of wind and waves. At the same time, two groups of damping structures are set to buffer the external forces acting on the space truss in the direction parallel to the length of the space truss. The tuned mass damper and the two groups of damping structures are combined to buffer all horizontal forces acting on the space truss.

[0010] Furthermore, the tuned mass damper includes a housing, a mass block located within the housing, and a fourth spring. The housing is rotatably connected to the two groups of damping structures at both ends. The housing is provided with a plurality of blades along its circumference. The mass block is slidably connected to the housing, and the two ends of the mass block are connected to the two ends of the housing via the fourth spring. When the spatial truss vibrates to one side, the mass block within the tuned mass damper moves in the opposite direction due to inertia. Simultaneously, the mass block, under the action of the fourth spring, moves left and right, in the opposite direction of the wave vibration, absorbing the external force of the wind and waves. After absorbing the force, the mass block returns to its original position under the action of the fourth spring. Simultaneously, the blades on the housing drive the entire tuned mass damper to rotate, absorbing the wind and waves.

[0011] Furthermore, the damping assembly includes a third elastic connecting plate, a first hydraulic damper, a second hydraulic damper, a third hydraulic damper, and a fourth elastic connecting plate, each of which includes a third connecting portion, a second curved portion, and a fourth connecting portion, each of which is connected in sequence. The third connecting portion is connected to the spatial truss, and the fourth connecting portion is connected to the first hydraulic damper or the third hydraulic damper. The first hydraulic damper and the third hydraulic damper each form an angle with the second hydraulic damper, and the first hydraulic damper and the third hydraulic damper are symmetrically arranged. The hydraulic damper and the spatial truss are connected by the elastic connecting plate. When the end of the spatial truss connected to the elastic buffer assembly deforms, the damping assembly provides resistance to the deformation, dissipating the external force applied to the spatial truss, reducing the frequency of adjustment, and protecting the spatial truss from rapid impact forces. At the same time, the deformation of the first curved portion on the elastic connecting plate provides deformation and buffer space, preventing the hydraulic damper from directly pulling on the spatial truss and causing large deformation of the spatial truss, and also preventing the hydraulic damper from separating from the spatial truss.

[0012] Furthermore, the damping assembly includes a plurality of fourth hydraulic dampers distributed along the length of the space truss, with each end of the fourth hydraulic damper connected to two sides of the space truss along the width direction. The fourth hydraulic dampers are located in the middle of the space truss along the height direction. The addition of the fourth hydraulic dampers in the middle of the space truss along the height direction protects the space truss from rapid lateral impact forces and prevents significant lateral deformation.

[0013] Furthermore, the space truss is set to an inverted trapezoidal structure, the space truss includes four cross beams and a plurality of first support rods, second support rods, first support cross rods, second support cross rods and third support rods, the four cross beams are distributed in a rectangular shape, two adjacent cross beams are connected by the first support rod and the second support rod, the first support rod and the second support rod are arranged at intervals, the first support rod and the second support rod both have an angle with the cross beam, and the first support rod and the second support rod are symmetrically arranged, the two ends of the first support cross rod are respectively connected to the middle of the first support rod and the second support rod, the two ends of the second support cross rod are respectively connected to the two first support cross rods located on opposite sides, and the two ends of the third support rod are respectively connected to two adjacent cross beams, the third support rod is located at the top and bottom ends of the space truss, and the third support rod is located between the first support rod and the second support rod; the two ends of the cross beam are respectively connected to the fixing frame and the elastic buffer assembly. By setting the spatial truss to an inverted trapezoid, when bearing vertical loads, the wider upper part can better disperse the load, make the force distribution inside the structure more uniform, and reduce the stress concentration on the components; setting the first support rod and the second support rod can effectively convert the vertical load into axial force and transmit it to the support, reducing the bending moment of the rod, allowing the material to more fully exert its strength performance, and improving the overall load-bearing efficiency of the structure; setting the first support cross bar further enhances the axial bearing capacity, and setting the second support cross bar and the third support rod further enhances the lateral bearing capacity.

[0014] Furthermore, the device further includes a power mechanism comprising a horizontal propeller, a vertical propeller, and a steering gear, wherein the horizontal propeller and the vertical propeller are respectively connected to the aquaculture equipment via the steering gear. By providing the power mechanism, in extremely severe weather conditions, the steering gear is activated to adjust the horizontal and vertical propellers to appropriate angles, and the horizontal and vertical propellers are activated to resist waves, thereby further improving the overall wind and wave resistance of the device.

[0015] Furthermore, the buoyancy buffer device also includes an angle adjustment mechanism, the floating plate includes a telescopic rod and two floating blocks, the two floating blocks are respectively located on either side of the space truss, the ends of the telescopic rod are respectively connected to the two floating blocks, and the two floating blocks are respectively connected to the space truss through the angle adjustment mechanism; the angle adjustment mechanism includes a connecting rod and an electric drive joint, the ends of the connecting rod are respectively connected to the floating blocks and the space truss through the electric drive joint. When the equipment needs to further improve its anti-overturning performance, the electric drive joint is activated, and the electric drive joint drives the connecting rod to rotate, expanding the distance between the two floating blocks, allowing the space truss to move downward toward the water surface as a whole, and bringing the overall center of gravity of the equipment closer to the water surface, thereby improving its wind and wave resistance.

[0016] Furthermore, the aquaculture equipment includes a support platform, an equipment platform, and a lifting and weight adjustment device. The buffer frame assembly is connected to the support platform, and the ends of the lifting and weight adjustment device are connected to the support platform and the equipment platform, respectively. By setting the lifting and weight adjustment device to rise and fall between the support platform and the equipment platform, the center of gravity height of the aquaculture equipment is adjusted, thereby further improving the overall wind and wave resistance of the equipment.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The deep-sea aquaculture equipment of the present invention uses a float to stably float the entire equipment on the sea surface, and dilutes the external force of wind and waves by providing a buoyancy buffer device. The buoyancy buffer device utilizes the good wind and wave resistance of the space truss for buffering, and by connecting the space truss with the fixed frame, the elastic buffer component and a number of damping components, the overall tolerance limit of the buffer frame component is improved, thereby preventing the external force of wind and waves from affecting the aquaculture equipment and making the equipment as a whole have better wind and wave resistance.

[0019] 2. A deep-sea aquaculture equipment of the present invention has a certain fixing effect on the unfixed end of the space truss by arranging multiple groups of elastic parts. At the same time, multi-level adjustment is performed when encountering wind and waves, so that the adjustment range is larger and the unfixed end of the space truss is more stable; the spring and the space truss are connected by an elastic connecting plate. When the elastic part is deformed to provide buffering when impacted, the first bent part on the elastic connecting plate is deformed to provide deformation and buffer space, thereby preventing the elastic part from directly pulling the space truss to cause large deformation of the space truss, and also preventing the elastic part from separating from the space truss.

[0020] 3. The deep-sea aquaculture equipment of the present invention is provided with a power mechanism. In extremely severe weather conditions, the steering gear is started to adjust the horizontal propeller and the vertical propeller to a suitable angle, and the horizontal propeller and the vertical propeller are started to resist the waves, thereby further improving the overall wind and wave resistance of the equipment.

[0034] Example 1

[0035] This embodiment is the first embodiment of a deep-sea aquaculture device. Figure 1 As shown, it includes a breeding device 100 and a buoyancy buffer device 200, as shown in FIG. Figure 2 As shown, the buoyancy buffer device 200 includes a buffer frame assembly 300 and a floating plate 400, and the farming equipment 100 is connected to the floating plate 400 through the buffer frame assembly 300; Figure 5 As shown, the buffer frame assembly 300 includes a space truss 310, a fixed frame 320, an elastic buffer assembly 330 and a plurality of damping assemblies 340. The space truss 310 is mainly used to bear longitudinal loads, that is, loads along the length direction of the space truss 310. The space truss 310 has a low ability to bear transverse loads, that is, loads along the width direction of the space truss 310. However, the external force brought by the wind and waves on the sea surface is the superposition of transverse loads and longitudinal loads, and the tolerance limit of ordinary space trusses 310 directly applied on the sea surface is relatively low. Therefore, the present application enhances the transverse load bearing capacity of the space truss 310, specifically by connecting the space truss 310 to the fixed frame 320, the elastic buffer assembly 330 and a plurality of damping assemblies 340 on the basis of the space truss 310.

[0036] The two sides of one longitudinal end of the spatial truss 310 are connected to the fixed frame 320, and the two sides of the other longitudinal end of the spatial truss 310 are connected to the two ends of the elastic buffer assembly 330. The two ends of the plurality of damping assemblies 340 are respectively connected to the two sides of the spatial truss 310 along the width direction, and the plurality of damping assemblies 340 are located between the fixed frame 320 and the elastic buffer assembly 330. When both ends of the truss are open, the truss is loose and will continue to deform when subjected to external forces. When both ends of the truss are closed, when the truss is subjected to external forces, the impact of the waves will fully exert force on the truss structure itself, and the truss will be easily deformed due to excessive force. The present invention connects the two ends of the space truss 310 to the fixing frame 320 and the elastic buffer assembly 330 respectively, and sets the space truss 310 as a structure with one end open and the other end closed, that is, the end where the space truss 310 is connected to the fixing frame 320 is a closed end, and the end where the space truss 310 is connected to the elastic buffer assembly 330 is an open end. While the space truss 310 has a fixed shape through the fixing frame 320 at the closed end, the elastic buffer assembly 330 is used to adjust the opening, so that the force applied to the space truss 310 is buffered by the elastic buffer assembly 330 and then restored, thereby consuming the force applied to the space truss 310.

[0037] like Figure 3 As shown, the elastic buffer component 330 includes an elastic component 331 and a balancing buffer component 332. Both ends of the elastic component 331 and the balancing buffer component 332 are respectively connected to the two sides of the spatial truss 310 along the width direction, and the elastic component 331 is located between the damping component 340 and the balancing buffer component 332.

[0038] like Figure 6 As shown, the elastic component 331 includes multiple groups of elastic members, which are distributed along the length direction of the space truss 310; the elastic members include a first elastic connecting plate 331a, a first spring 331b, a second spring 331c, a third spring 331d and a second elastic connecting plate 331e connected in sequence, and the first elastic connecting plate 331a and the second elastic connecting plate 331e both include a first connecting portion, a first bent portion and a second connecting portion connected in sequence, the first connecting portion, the first bent portion and the second connecting portion are an integrally formed structure, and the material used is a material with a certain toughness such as gear steel, the first bent portion is bent toward the first elastic connecting plate 331a, the first connecting portion is connected to the space truss 310, and the second connecting portion is connected to the first spring 331b or the third spring 331d, the first spring 331b and the third spring 331d both have an angle with the second spring 331c, and the first spring 331b and the third spring 331d are symmetrically arranged. In this embodiment, the first spring 331b and the third spring 331d are both inclined at 45 degrees, which can consume forces in multiple directions.

[0039] By providing multiple sets of elastic members, the unattached end of the space truss 310 is stabilized to a certain extent. This allows for multi-level adjustment when encountering wind and waves, extending the adjustment range and making the unattached end of the space truss 310 more stable. Specifically, during adjustment, the outer elastic members deform more significantly, while the inner elastic members deform less. An elastic connecting plate connects the springs to the space truss 310. When impacted, the elastic members deform to provide cushioning. The first curved portion of the elastic connecting plate deforms, providing deformation and cushioning space. This prevents the elastic members from directly pulling on the space truss 310, causing significant deformation, and also prevents the elastic members from separating from the space truss 310. In this embodiment, the first, second, and third springs 331b, 331c, and 331d are all hard springs, also known as high-rigidity springs, i.e., springs with high elastic coefficients. These springs are difficult to deform and produce less deformation under the same force, thus maintaining the overall structural stability of the space truss 310.

[0040] like Figure 6 As shown, the balancing buffer assembly 332 includes a tuned mass damper 332a and two groups of damping structures 332b. The two ends of the tuned mass damper 332a are respectively connected to the two groups of damping structures 332b. The two groups of damping structures 332b are respectively connected to the two sides of the space truss 310 along the width direction. The tuned mass damper is arranged along the width direction of the space truss 310, and the two groups of damping structures 332b are both arranged along the length direction of the space truss 310. By setting up a tuned mass damper 332a, the tuned mass damper 332a will produce a larger response due to the resonance of the sea water fluctuations, and its frequency will be tuned to be consistent with the horizontal vibration frequency of the waves, thereby consuming the external force of wind and waves; at the same time, two sets of damping structures 332b are set up to buffer the external force parallel to the length direction of the space truss 310 exerted on the space truss 310; the tuned mass damper 332a and the two sets of damping structures 332b are combined to buffer the horizontal forces exerted on the space truss 310.

[0041] The tuned mass damper 332a comprises a housing, a mass block located within the housing, and a fourth spring. The housing's ends are rotatably connected to two sets of damping structures 332b. The housing is circumferentially provided with multiple blades. The mass block is slidably connected to the housing, and its ends are connected to the housing's ends via the fourth spring. When the spatial truss 310 vibrates to one side, the mass block within the tuned mass damper 332a moves in the opposite direction due to inertia. Simultaneously, the mass block, driven by the fourth spring, moves left and right, in the opposite direction of the wave vibration, dissipating the external force of the wind and waves. After this dissipation, the mass block returns to its original position under the action of the fourth spring. Simultaneously, the blades on the housing drive the entire tuned mass damper 332a to rotate, dissipating the wind and waves.

[0042] like Figure 8As shown, the damping assembly 340 includes a third elastic connecting plate 341, a first hydraulic damper 342, a second hydraulic damper 343, a third hydraulic damper 344 and a fourth elastic connecting plate 345 connected in sequence. The structures of the third elastic connecting plate 341 and the fourth elastic connecting plate 345 include a third connecting portion, a second bending portion and a fourth connecting portion connected in sequence. The third connecting portion is connected to the spatial truss 310, and the fourth connecting portion is connected to the first hydraulic damper 342 or the third hydraulic damper 344. The first hydraulic damper 342 and the third hydraulic damper 344 both have an angle with the second hydraulic damper 343, and the first hydraulic damper 342 and the third hydraulic damper 344 are symmetrically arranged. The hydraulic damper and the space truss 310 are connected by an elastic connecting plate. When one end of the space truss 310 connected to the elastic buffer component 330 is deformed, the damping component 340 provides resistance to the deformation, consumes the external force exerted on the space truss 310, reduces the adjustment frequency, and prevents the space truss 310 from being subjected to rapid impact force. At the same time, the deformation of the first bent portion on the elastic connecting plate provides deformation and buffer space, preventing the hydraulic damper from directly pulling the space truss 310 to cause a large deformation of the space truss 310, and also preventing the hydraulic damper from separating from the space truss 310.

[0043] like Figure 8 As shown, the damping assembly 340 further includes a plurality of fourth hydraulic dampers 346, which are distributed along the length of the space truss 310. The fourth hydraulic dampers 346 are connected at both ends to the width of the space truss 310, and are located in the middle of the height of the space truss 310. The addition of the fourth hydraulic dampers 346 in the middle of the height of the space truss 310 protects the space truss 310 from rapid lateral impact forces and prevents significant lateral deformation.

[0044] When subjected to an external force, the piston rod in the hydraulic damper drives the piston into the cylinder, reducing the volume of the chamber on one side of the piston. The hydraulic oil is squeezed through the damping orifice or other throttling device on the piston to flow to the other chamber. Due to the small diameter of the damping orifice, the hydraulic oil encounters significant resistance when passing through it. According to Poiseuille's law, when a liquid flows in a narrow tube, the flow rate is proportional to the fourth power of the tube diameter and inversely proportional to the tube length and the liquid viscosity. Therefore, a large pressure differential is generated at the damping orifice, generating a damping force that hinders the movement of the piston, providing cushioning and vibration reduction. When the external force disappears or the damper is stretched, the piston moves in the opposite direction. At this time, the hydraulic oil in the other chamber flows back through the damping orifice to the original chamber, generating a damping force as well, preventing the piston from quickly returning to its original position and thus controlling its movement.

[0045] like Figure 7 As shown, the space truss 310 is configured as an inverted trapezoidal structure, as shown in FIG. Figure 4As shown, the space truss 310 includes four cross beams 311 and a plurality of first support rods 312, second support rods 313, first support cross rods 314, second support cross rods 315 and third support rods 316. The four cross beams 311 are distributed in a rectangular shape. Two adjacent cross beams 311 are connected by the first support rod 312 and the second support rod 313. The first support rod 312 and the second support rod 313 are arranged at intervals. The first support rod 312 and the second support rod 313 both have an angle with the cross beam 311, and the first support rod 312 and the second support rod 313 are symmetrically arranged. The ends of the first support crossbar 314 are respectively connected to the middle portions of the first support bar 312 and the second support bar 313. The ends of the second support crossbar 315 are respectively connected to the two first support crossbars 314 located on opposite sides. The ends of the third support bar 316 are respectively connected to two adjacent crossbeams 311. The third support bar 316 is located at the top and bottom ends of the space truss 310, and between the first support bar 312 and the second support bar 313. The ends of the crossbeam 311 are respectively connected to the fixing frame 320 and the elastic buffer assembly 330. By adopting an inverted trapezoidal structure as the overall space truss 310, which is wider at the top and narrower at the bottom, the wider top portion can better distribute the load when subjected to vertical loads (such as deadweight), making the internal force distribution more uniform and reducing stress concentration in the components. Furthermore, the diagonal web members of the inverted trapezoidal structure can more effectively resist lateral loads (such as wave impact) and transmit horizontal forces to the foundation through axial tension and compression of the members, thereby improving the overall lateral stiffness of the structure. In addition, the inverted trapezoidal structure can leave more space at the bottom while meeting the load-bearing requirements, which is convenient for the placement of equipment below. Cables and other facilities can be laid. And under the premise of meeting the same load-bearing capacity and usage functions, the inverted trapezoidal structure can appropriately reduce the amount of material due to its more reasonable force. By optimizing the size and layout of the rods, it can reduce costs while ensuring the safety of the structure, which is more economical. The first support rod 312 and the second support rod 313 can effectively convert the vertical load into an axial force and transmit it to the support, reducing the bending moment of the rod, so that the material can more fully exert its strength performance and improve the overall load-bearing efficiency of the structure; the first support cross bar 314 is provided to further enhance the axial bearing capacity, and the second support cross bar 315 and the third support rod 316 are provided to further enhance the lateral bearing capacity.

[0046] In this embodiment, the space truss 310 is rectangular. Its left and right sides are based on a Warren truss with the addition of a first support bar 314 and a second support bar 315. Its upper and lower sides are improved Warren trusses, with the addition of a third support bar 316. To ensure the entire device floats on the sea, the space truss 310 is constructed of lightweight materials such as aluminum alloy.

[0047] The working principle of the deep-sea aquaculture equipment of this embodiment is as follows:

[0048] When using the aquaculture equipment 100 for marine aquaculture, the buoyancy buffer device 200 floats the aquaculture equipment 100 as a whole on the sea surface. When encountering wind and waves, the float 400 transfers the external force to the buffer frame assembly 300 for buffering. The buffer frame assembly 300 dilutes the external force to avoid transmitting the external force to the aquaculture equipment 100, and at the same time allows the entire equipment to float stably on the sea surface and have good wind and wave resistance. The buffer frame assembly 300 is configured to include a space truss 310, a fixed frame 320, an elastic buffer assembly 330 and several damping assemblies 340, and the good wind and wave resistance of the space truss 310 is used for buffering. However, the space truss 310 itself is rigidly connected internally, and has high sensitivity and tolerance limits. When the wind and waves are large, the space truss 310 is easy to fall apart. Therefore, one end of the space truss 310 is connected to the fixed frame 320, so that the space truss 310 has a fixed shape, and the other end of the space truss 310 is connected to the elastic buffer assembly 330. When it is affected by wind and waves, it vibrates through the elastic assembly 331, and the vibration is consumed by the balancing buffer assembly 332. At the same time, resistance is provided by the damping assembly 340 during vibration to avoid large vibrations in the middle section of the space truss 310, so that the external force generated by wind and waves on the space truss 310 tends to be stable, and then the overall structure of the space truss 310 is restored by the elastic assembly 331, thereby further improving the tolerance limit of the buffer frame assembly 300 as a whole. The floating plate 400 is used to float the entire equipment stably on the sea surface, and the external force of wind and waves is diluted by setting up a buoyancy buffer device 200. The buoyancy buffer device 200 uses the good wind and wave resistance of the space truss 310 for buffering, and by connecting the space truss 310 with the fixed frame 320, the elastic buffer component 330 and several damping components 340, the overall tolerance limit of the buffer frame component 300 is improved, avoiding the external force of wind and waves from affecting the breeding equipment 100, so that the equipment as a whole has better wind and wave resistance.

[0049] Example 2

[0050] This embodiment is the second embodiment of the deep-sea aquaculture equipment. This embodiment is similar to the first embodiment, except that Figure 9 As shown, the apparatus 100 further includes a power mechanism 600, which includes a horizontal propeller 610, a vertical propeller 620, and a steering gear 630. The horizontal propeller 610 and the vertical propeller 620 are connected to the aquaculture equipment 100 via the steering gear 630. By providing the power mechanism 600, in extremely severe weather conditions, the steering gear 630 is activated to adjust the horizontal propeller 610 and the vertical propeller 620 to a suitable angle, and the horizontal propeller 610 and the vertical propeller 620 are activated to resist the waves, thereby further improving the overall wind and wave resistance of the apparatus.

[0051] In this embodiment, there are four horizontal propellers 610, which are respectively installed on the sides of the farming equipment 100. By changing the installation direction of the horizontal propellers 610, an upward or downward thrust can be generated on the farming equipment 100, thereby achieving the vertical ascent or descent of the equipment. There are six vertical propellers 620, two of which are installed between the two horizontal propellers 610 on the same side, and the remaining four vertical propellers 620 are installed at the four corners of the bottom of the farming equipment 100. The four vertical propellers 620 are arranged at an angle. By changing the rotation direction of the vertical propellers 620, the horizontal components of force in different directions generated by their tilted installation can be used to achieve forward and backward movement of the equipment. At the same time, the difference in thrust of the propellers on the left and right sides can achieve turning.

[0052] Example 3

[0053] This embodiment is the third embodiment of the deep-sea aquaculture equipment. This embodiment is similar to the first embodiment, except that Figure 2 As shown, the buoyancy buffer device 200 further includes an angle adjustment mechanism 500, as shown in FIG. Figure 3 and Figure 5 As shown, the floating plate 400 includes a telescopic rod 410 and two floating blocks 420. The two floating blocks 420 are respectively located on both sides of the space truss 310. The two ends of the telescopic rod 410 are respectively connected to the two floating blocks 420. The two floating blocks 420 are respectively connected to the space truss 310 through the angle adjustment mechanism 500. Figure 3 As shown, the angle adjustment mechanism 500 includes a connecting rod 510 and an electrically driven joint 520. The two ends of the connecting rod 510 are connected to the buoys 420 and the space truss 310, respectively, via the electrically driven joints 520. When the equipment needs to further improve its anti-overturning performance, the electrically driven joints 520 are activated. The electrically driven joints 520 are common commercially available electrically driven joints that can be electrically driven and rotated. The electrically driven joints 520 drive the connecting rod 510 to rotate, increasing the distance between the two buoys 420 and causing the space truss 310 to move downward toward the water surface. This brings the overall center of gravity of the equipment closer to the water surface, thereby improving its wind and wave resistance. In this embodiment, the buoys 420 use large, high-strength buoys, and the telescopic rods 410 utilize a three-stage nested hydraulic drive structure, providing a thrust of up to 10 kN.

[0054] In this embodiment, floating plates 400 are installed at both ends of the spatial truss 310. Four sets of angle adjustment mechanisms 500 are provided at one end. The spatial truss 310 is connected to a support frame. One end of each of the four angle adjustment mechanisms 500 is connected to the four corners of the support frame, while the other ends of two sets of angle adjustment mechanisms 500 are connected to the floating blocks 420 on one side, and the other ends of two sets of angle adjustment mechanisms 500 are connected to the floating blocks 420 on the other side. The support frame is also equipped with a signal receiving antenna and a signal converter. When controlling the electrically driven joint 520, a signal is transmitted. The signal receiving antenna receives the signal, and the signal converter converts the received electromagnetic wave signal into an electrical signal of a certain frequency, thereby enabling remote control of the electrically driven joint 520.

[0055] like Figure 10 As shown, the farming equipment 100 includes a support platform 110, an equipment platform 120, and a lifting and weight adjustment device 130. The buffer frame assembly 300 is connected to the support platform 110, and the two ends of the lifting and weight adjustment device 130 are respectively connected to the support platform 110 and the equipment platform 120. By setting the lifting and weight adjustment device 130 to rise and fall between the support platform 110 and the equipment platform 120, the center of gravity height of the farming equipment 100 is adjusted, thereby further improving the overall wind and wave resistance of the equipment. In this embodiment, the lifting and weight adjustment device 130 includes a lifting mechanism and a cargo compartment. A mounting port is provided on the second platform 121. The lifting mechanism is installed at the mounting port. The cargo compartment is connected to the output end of the lifting mechanism. The lifting mechanism uses a common lifting mechanism available on the market. Sandbags or oil drums can be filled in the cargo compartment to adjust the weight as needed. By controlling the lifting height of the lifting mechanism, the relative position of the cargo compartment and the equipment surface is changed, thereby adjusting the center of gravity distribution of the equipment, effectively improving the anti-overturning performance of the equipment.

[0056] like Figure 10As shown, the equipment platform 120 includes a second platform 121 and an intelligent control center 122, an energy supply system 123, a lifting and feeding device 124, and a robotic arm clamping device 125, all of which are located on the second platform 121. The buoyancy buffer device 200, the energy supply system 123, the lifting and feeding device 124, and the robotic arm clamping device 125 are all communicatively connected to the intelligent control center 122. The buoyancy buffer device 200, the intelligent control center 122, the lifting and feeding device 124, and the robotic arm clamping device 125 are all electrically connected to the energy supply system 123. The energy supply system 123 is controlled to supply power to the aquaculture equipment 100, the aquaculture equipment 100 is intelligently controlled through the intelligent control center 122, the lifting and feeding device 124 is used to feed the organisms in the aquaculture area, and the robotic arm clamping device 125 can be used to clamp objects on the sea surface. In this embodiment, the intelligent control center 122 includes an intelligent control console, water quality sensors, underwater cameras, and water quality oxygen content sensors. The intelligent control console controls the equipment, and the water quality sensors, underwater cameras, and water quality oxygen content sensors collect underwater environmental data in real time, such as key indicators such as water temperature, salinity, pH, and dissolved oxygen concentration. Other sensors can also be set to collect underwater environmental data, which is beneficial to ensuring the quality of marine aquaculture, improving aquaculture efficiency, and reducing aquaculture costs to a certain extent. The energy supply system 123 uses solar photovoltaic panels to power the equipment using solar energy. The lifting and feeding device 124 uses a spiral gravity conveying mechanism to accurately control the release of bait. The robotic arm clamping device 125 includes a robotic arm and a clamping claw. The position of the clamping claw is controlled by the robotic arm, and the clamping claw is then used to clamp the object, thereby achieving the clamping and transportation of the object.

[0057] like Figure 6As shown, the support platform 110 includes a first platform 111 and a magnetic delivery device 112 and a ballast water tank device 113, both of which are arranged on the first platform 111. The magnetic delivery device 112 and the ballast water tank device 113 are both connected to the intelligent control center 122 for communication, and are both electrically connected to the energy supply system 123. By providing the ballast water tank device 113, the height of the entire equipment in the deep sea can be changed, allowing the entire equipment to sink and float in the deep sea; by providing the magnetic delivery device 112, an underwater robot can be launched. In this embodiment, the magnetic delivery device 112 includes a mounting plate and an electromagnet. When the electromagnet is energized, the electromagnet can attract the underwater robot. When the electromagnet is de-energized, the electromagnet loses its magnetism and separates from the underwater robot, allowing the underwater robot to be launched. The ballast water tank device 113 includes a water filling tank, a suction valve, a discharge valve and a ballast water pump. By turning on the ballast water pump and controlling the suction valve and the discharge valve, the water volume in the water filling tank is adjusted, thereby adjusting the lifting height of the equipment in the seawater, further enhancing the equipment's anti-overturning performance, and enabling it to operate more stably and safely in complex offshore environments.
