Description

Technical Field

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

[0002] At present, marine aquaculture mostly adopts the traditional in - shore aquaculture mode. However, the in - shore aquaculture has the following problems: limited space, and is easily affected by pollution and diseases; high costs for artificial feeding, monitoring and maintenance, and is greatly affected by weather; lack of accurate data support, relying on empirical judgment, and it is difficult to achieve scientific and refined aquaculture management.

[0003] With the increasing demand for global marine resource development, the traditional aquaculture mode has been difficult to meet people's needs, and deep - sea and far - sea aquaculture has become an important development direction. However, the deep - sea and far - sea environment is complex and the weather is changeable. The anti - wave ability of traditional offshore aquaculture equipment is relatively low, and it is difficult to adapt to the harsh and changeable weather environment in the deep sea. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiency of the relatively low anti - wave ability of offshore aquaculture equipment in the prior art, and provide a deep - sea and far - sea aquaculture equipment with better anti - wave ability.

[0005] To solve the above - mentioned technical problems, the technical solution adopted by the present invention is: Provide a deep - sea and far - sea aquaculture equipment, including an aquaculture equipment and a buoyancy buffer device. The buoyancy buffer device includes a buffer frame assembly and a floating board. The aquaculture equipment is connected to the floating board through the buffer frame assembly. The buffer frame assembly includes a space truss, a fixed frame, an elastic buffer assembly and a number of damping components. Both sides at one end of the space truss in the length direction are connected to the fixed frame. Both sides at the other end of the space truss in the length direction are connected to both ends of the elastic buffer assembly. Both ends of the number of damping components are respectively connected to both sides of the space truss in the width direction, and the number of damping components are located between the fixed frame and the elastic buffer assembly. The elastic buffer assembly includes an elastic component and a balance buffer component. Both ends of the elastic component and the balance buffer component are respectively connected to both sides of the space truss in the width direction, and the elastic component is located between the damping component and the balance buffer component.

[0006] The deep-sea aquaculture equipment of the present invention, when using the aquaculture equipment for offshore aquaculture, the buoyancy buffer device floats the aquaculture equipment as a whole on the sea surface, and when encountering wind and waves, the floating plate transfers the external force received to the buffer frame assembly for buffering, and the buffer frame assembly dilutes the external force to avoid transmitting the external force to the aquaculture equipment, while allowing the equipment as a whole to float stably on the sea surface and have good wind and wave resistance. The buffer frame component is configured as a space truss, a fixed frame, an elastic buffer component and several damping components, 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 limit. 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 component. When affected by wind and waves, the elastic component vibrates, and the vibration is consumed by the balancing buffer component. At the same time as the vibration, the damping component 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 component, thereby further improving the overall tolerance limit of the buffer frame component. The floating plate is used to make the whole equipment float stably on the sea surface, and the external force of wind and waves is diluted by setting up a buoyancy buffer device. The good wind and wave resistance ability of the space truss is used for buffering in the buoyancy buffer device. The connection between the space truss and the fixed frame, the elastic buffer component and several damping components is used to improve the overall tolerance limit of the buffer frame component, so as to avoid the influence of wind and wave external forces on the breeding equipment and make the equipment have better wind and wave resistance as a whole.

[0007] Further, the elastic component includes multiple groups of elastic members, and the multiple groups of elastic members are distributed along the length direction of the space truss; the elastic member includes a first elastic connecting plate, a first spring, a second spring, a third spring and a second elastic connecting plate connected in sequence, the first elastic connecting plate and the second elastic connecting plate each include a first connecting portion, a first bending portion and a second connecting portion connected in sequence, the first connecting portion is connected to the space truss, the second connecting portion is connected to the first spring or the third spring, the first spring and the third spring both have an angle with the second spring, and the first spring and the third spring are symmetrically arranged. By setting multiple groups of elastic members, a certain solidification effect is provided on the unfixed end of the space truss, and 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, and when impacted, the elastic member is deformed for buffering, and at this time, the first bending portion on the elastic connecting plate is deformed to provide deformation and buffering space, so as to avoid the elastic member directly pulling the space truss to cause a large deformation of the space truss, and also to avoid the separation of the elastic member from the space truss.

[0008] Furthermore, the balance buffer assembly includes a tuned mass damper and two sets of damping structures. Both ends of the tuned mass damper are respectively connected to the two sets of damping structures, and the two sets of damping structures are respectively connected to both sides of the space truss in the width direction. The tuned mass damper is arranged along the width direction of the space truss, and both sets of damping structures are arranged along the length direction of the space truss. By setting the tuned mass damper, the tuned mass damper will generate a large response due to the resonance of the seawater fluctuations, and its frequency will be tuned to be consistent with the horizontal vibration frequency of the sea waves, consuming the external force of the wind and waves. At the same time, two sets of damping structures are set to buffer the external force parallel to the length direction of the space truss received by the space truss. Combining the tuned mass damper and the two sets of damping structures buffers all the horizontal forces received by the space truss.

[0009] Furthermore, the tuned mass damper includes a housing, a mass block and a fourth spring located inside the housing. Both ends of the housing are respectively rotatably connected to the two sets of damping structures. The housing is provided with a plurality of blades along the circumferential direction. The mass block is slidably connected to the housing, and both ends of the mass block are respectively connected to both ends of the housing through the fourth spring. When the space truss vibrates to one side, the mass block inside the tuned mass damper will move in the opposite direction due to inertia. At the same time, the mass block will move left and right under the action of the fourth spring, in the opposite direction to the vibration direction of the sea waves, consuming the external force of the wind and waves, and resetting under the action of the fourth spring after the consumption ends. At the same time, the blades on the housing will drive the entire tuned mass damper to rotate, consuming the wind and waves.

[0010] 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 connected in sequence. The structures of the third elastic connecting plate and the fourth elastic connecting plate both include a third connecting part, a second bending part and a fourth connecting part connected in sequence. The third connecting part is connected to the space truss, and the fourth connecting part is connected to the first hydraulic damper or the third hydraulic damper. The first hydraulic damper and the third hydraulic damper both form an angle with the second hydraulic damper, and the first hydraulic damper and the third hydraulic damper are symmetrically arranged. By connecting the hydraulic damper and the space truss through the elastic connecting plate, when one end of the space truss connected to the elastic buffer assembly deforms, the damping assembly provides resistance to the deformation, consumes the external force received by the space truss, reduces the adjustment frequency, and avoids the space truss from being subjected to a rapid impact force. At the same time, the first bending part on the elastic connecting plate deforms to provide a deformation and buffer space, avoiding the hydraulic damper directly pulling the space truss to cause a large deformation of the space truss, and also avoiding the separation of the hydraulic damper from the space truss.

[0011] Further, the damping assembly further includes a plurality of fourth hydraulic dampers. The plurality of fourth hydraulic dampers are distributed along the length direction of the space truss. Two ends of each fourth hydraulic damper are respectively connected to two sides of the space truss along the width direction. The fourth hydraulic damper is located in the middle of the space truss along the height direction. By adding fourth hydraulic dampers in the middle of the space truss along the height direction, the space truss is prevented from being subjected to a relatively fast lateral impact force and large lateral deformation is avoided.

[0012] Further, the space truss is arranged in an inverted trapezoidal structure. The space truss includes four cross beams, and a plurality of first support rods, second support rods, first support cross bars, second support cross bars and third support rods. The four cross beams are distributed in a rectangle. 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. Both the first support rod and the second support rod form an angle with the cross beam, and the first support rod and the second support rod are symmetrically arranged. Two ends of the first support cross bar are respectively connected to the middle parts of the first support rod and the second support rod. Two ends of the second support cross bar are respectively connected to two first support cross bars located on opposite sides. 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 of the space truss. The third support rod is located between the first support rod and the second support rod. Two ends of the cross beam are respectively connected to the fixed frame and the elastic buffer assembly. By arranging the space truss in an inverted trapezoid, when bearing vertical loads, the wider upper part can better disperse the loads, making the internal force distribution of the structure more uniform and reducing the stress concentration on the components. Arranging 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, enabling the material to give full play to its strength performance and improving the overall load-bearing efficiency of the structure. Arranging the first support cross bar further enhances the axial bearing capacity, and arranging the second support cross bar and the third support rod further enhances the lateral bearing capacity.

[0013] Further, a power mechanism is further included. The power mechanism includes a horizontal propeller, a vertical propeller and a steering gear. The horizontal propeller and the vertical propeller are respectively connected to the breeding equipment through the steering gear. By arranging the power mechanism, in extremely bad weather conditions, the steering gear is started to adjust the horizontal propeller and the vertical propeller to appropriate angles, and the horizontal propeller and the vertical propeller are started to resist the sea waves, thereby further enhancing the overall wave resistance ability of the equipment.

[0014] 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 both sides of the space truss, the two 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, and the two 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 started, 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 allowing the overall center of gravity of the equipment to be closer to the water surface, thereby improving its wind and wave resistance.

[0015] Furthermore, the farming equipment includes a support platform, an equipment platform and a lifting and weight-adjusting device, the buffer frame assembly is connected to the support platform, and the two ends of the lifting and weight-adjusting device are respectively connected to the support platform and the equipment platform. By setting the lifting and weight-adjusting device to rise and fall between the support platform and the equipment platform, the height of the center of gravity of the farming equipment is adjusted, thereby further improving the overall wind and wave resistance of the equipment.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. A deep-sea aquaculture equipment of the present invention uses a floating plate to stably float the entire equipment on the sea surface, and dilutes the external force of wind and waves by setting a buoyancy buffer device. The buoyancy buffer device uses the good wind and wave resistance of the space truss for buffering, and by connecting the space truss with a fixed frame, an elastic buffer component and a plurality of damping components, the overall tolerance limit of the buffer frame component is improved, the external force of wind and waves is prevented from affecting the aquaculture equipment, and the equipment as a whole has better wind and wave resistance.

[0017] 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, and when the elastic part is impacted, it is deformed to buffer. At this time, the first bent part on the elastic connecting plate is deformed to provide deformation and buffer space, so as to prevent the elastic part from directly pulling the space truss to cause a large deformation of the space truss, and also to prevent the elastic part from separating from the space truss.

[0018] 3. The deep-sea aquaculture equipment of the present invention is provided with a power mechanism. Under 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.

[0023] Embodiment 1 This embodiment is the first embodiment of a deep-sea and far-sea aquaculture device. As Figure 1 shown, it includes an aquaculture device 100 and a buoyancy buffer device 200. As Figure 2 shown, the buoyancy buffer device 200 includes a buffer frame assembly 300 and a floating board 400. The aquaculture device 100 is connected to the floating board 400 through the buffer frame assembly 300. As Figure 5As shown, the buffer frame assembly 300 includes a space truss 310, a fixing frame 320, an elastic buffer assembly 330, and a number 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 relatively low bearing capacity for lateral loads, that is, loads along the width direction of the space truss 310. However, the external forces brought by the wind and waves on the sea surface are the superposition of lateral loads and longitudinal loads. The tolerance limit of ordinary space trusses 310 directly applied on the sea surface is relatively low. Therefore, in this application, the lateral load bearing capacity of the space truss 310 is enhanced. Specifically, on the basis of the space truss 310, the space truss 310 is connected to the fixing frame 320, the elastic buffer assembly 330, and a number of damping assemblies 340.

[0024] Both sides of one end of the space truss 310 along the length direction are connected to the fixing frame 320. Both sides of the other end of the space truss 310 along the length direction are connected to the two ends of the elastic buffer assembly 330. The two ends of a number of damping assemblies 340 are respectively connected to both sides of the space truss 310 along the width direction, and a number of damping assemblies 340 are located between the fixing frame 320 and the elastic buffer assembly 330. When both ends of the truss are open structures, both ends of the truss are in a loose state, and the truss will continue to deform when subjected to external forces; when both ends of the truss are closed structures, when the truss is subjected to external forces, the impact of the sea waves will apply force to the entire structure of the truss, and the truss is prone to deformation due to excessive force. In the present invention, both ends of the space truss 310 are respectively connected to the fixing frame 320 and the elastic buffer assembly 330, and the entire space truss 310 is set as a structure with one end open and one end closed, that is, the end of the space truss 310 connected to the fixing frame 320 is a closed end, and the end of the space truss 310 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 for opening adjustment to buffer and restore the force received by the space truss 310 through the elastic buffer assembly 330, consuming the force received by the space truss 310.

[0025] As Figure 3 shown, the elastic buffer assembly 330 includes an elastic component 331 and a balance buffer component 332. Both ends of the elastic component 331 and the balance buffer component 332 are respectively connected to both sides of the space truss 310 along the width direction. The elastic component 331 is located between the damping assembly 340 and the balance buffer component 332.

[0026] As Figure 6As shown, the elastic component 331 includes multiple groups of elastic members, and the multiple groups of elastic members 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 bending portion and a second connecting portion connected in sequence, and the first connecting portion, the first bending 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 bending 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, so as to consume forces in multiple directions.

[0027] By setting multiple groups of elastic parts, the unfixed end of the space truss 310 has a certain solidifying effect, and 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 310 is more stable, that is, when adjusting, the elastic parts on the outside are deformed more, while the elastic parts on the inside are deformed less. The spring and the space truss 310 are connected by an elastic connecting plate. When the elastic parts are impacted, they are deformed for buffering. At this time, the first curved part on the elastic connecting plate is deformed to provide deformation and buffer space, so as to avoid the elastic parts directly pulling the space truss 310 to cause a large deformation of the space truss 310, and also to avoid the separation of the elastic parts from the space truss 310. The first spring 331b, the second spring 331c and the third spring 331d in this embodiment are all hard springs, also known as high-rigidity springs, that is, springs with high elastic coefficients, which are difficult to deform and produce smaller deformations under the same force, so as to facilitate the stability of the overall structure of the space truss 310.

[0028] like Figure 6As shown in the figure, the balance buffer assembly 332 includes a tuned mass damper 332a and two sets of damping structures 332b. The two ends of the tuned mass damper 332a are respectively connected to the two sets of damping structures 332b. The two sets of damping structures 332b are respectively connected to the two sides of the space truss 310 in the width direction. The tuned mass damper is arranged along the width direction of the space truss 310, and the two sets of damping structures 332b are both arranged along the length direction of the space truss 310. By setting the tuned mass damper 332a, the tuned mass damper 332a will generate a large response due to the resonance of the seawater fluctuations, and its frequency will be tuned to be consistent with the horizontal vibration frequency of the sea waves to consume the external force of the wind and waves. At the same time, two sets of damping structures 332b are set to buffer the external force parallel to the length direction of the space truss 310 received by the space truss 310. Combining the tuned mass damper 332a and the two sets of damping structures 332b, the horizontal forces received by the space truss 310 are buffered.

[0029] The tuned mass damper 332a includes a housing, a mass block and a fourth spring located inside the housing. The two ends of the housing are respectively rotatably connected to the two sets of damping structures 332b. The housing is provided with a plurality of vanes in the circumferential direction. The mass block is slidably connected to the housing, and the two ends of the mass block are respectively connected to the two ends of the housing through the fourth spring. When the space truss 310 vibrates to one side, the mass block in the tuned mass damper 332a will move in the opposite direction due to inertia. At the same time, the mass block will move left and right under the action of the fourth spring, in the opposite direction to the vibration direction of the sea waves, to consume the external force of the wind and waves. After the consumption is over, it will reset under the action of the fourth spring. At the same time, the vanes on the housing will drive the entire tuned mass damper 332a to rotate to consume the wind and waves.

[0030] As 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 that are connected in sequence. The structures of the third elastic connecting plate 341 and the fourth elastic connecting plate 345 both include a third connecting portion, a second bending portion, and a fourth connecting portion that are connected in sequence. The third connecting portion is connected to the space 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 form an angle with the second hydraulic damper 343, and the first hydraulic damper 342 and the third hydraulic damper 344 are symmetrically arranged. By connecting the hydraulic dampers and the space truss 310 through elastic connecting plates, when one end of the space truss 310 connected to the elastic buffer assembly 330 deforms, the damping assembly 340 provides resistance to the deformation, consumes the external force received by the space truss 310, reduces the adjustment frequency, and avoids the space truss 310 from being subjected to rapid impact forces. At the same time, the first bending portion on the elastic connecting plate deforms to provide a deformation and buffering space, avoiding the hydraulic damper directly pulling the space truss 310 to cause large deformation of the space truss 310, and also avoiding the separation of the hydraulic damper from the space truss 310.

[0031] As Figure 8 shown, the damping assembly 340 further includes a plurality of fourth hydraulic dampers 346. The plurality of fourth hydraulic dampers 346 are distributed along the length direction of the space truss 310. Both ends of the fourth hydraulic damper 346 are respectively connected to both sides of the space truss 310 along the width direction. The fourth hydraulic damper 346 is located in the middle of the space truss 310 along the height direction. By adding the fourth hydraulic damper 346 in the middle of the space truss 310 along the height direction, the space truss 310 is prevented from being subjected to relatively fast lateral impact forces and from generating large lateral deformations.

[0032] When an external force is applied, the piston rod in the hydraulic damper drives the piston to move into the cylinder barrel, reducing the volume of the chamber on one side of the piston. The hydraulic oil is squeezed and flows through the damping hole or other throttling devices on the piston to the other chamber. Since the aperture of the damping hole is small, the hydraulic oil will be subjected to a large resistance when passing through. According to Poiseuille's law, when a liquid flows in a thin 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 difference will be formed at the damping hole, thereby generating a damping force to hinder the movement of the piston and playing a role in buffering 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 to the original chamber through the damping hole, and a damping force will also be generated to prevent the piston from quickly returning to its original position, thus controlling the movement.

[0033] As Figure 7 shown, the space truss 310 is provided with an inverted trapezoidal structure. As Figure 4As shown in the figure, the space truss 310 includes four cross beams 311 and a plurality of first support rods 312, second support rods 313, first support cross bars 314, second support cross bars 315 and third support rods 316. The four cross beams 311 are arranged in a rectangular distribution. Two adjacent cross beams 311 are connected by the first support rods 312 and the second support rods 313. The first support rods 312 and the second support rods 313 are arranged at intervals. Both the first support rods 312 and the second support rods 313 have an angle with the cross beam 311, and the first support rods 312 and the second support rods 313 are symmetrically arranged. The two ends of the first support cross bar 314 are respectively connected to the middle parts of the first support rod 312 and the second support rod 313. The two ends of the second support cross bar 315 are respectively connected to two first support cross bars 314 located on the opposite surfaces. The two ends of the third support rod 316 are respectively connected to two adjacent cross beams 311. The third support rod 316 is located at the top and bottom of the space truss 310. The third support rod 316 is located between the first support rod 312 and the second support rod 313. The two ends of the cross beam 311 are respectively connected to the fixing frame 320 and the elastic buffer assembly 330. By adopting an inverted trapezoidal structure for the whole space truss 310, the upper part of the inverted trapezoidal structure is wider and the lower part is narrower. When bearing vertical loads (such as self-weight), the wider upper part can better disperse the loads, making the internal force distribution of the structure more uniform and reducing the stress concentration on the components. At the same time, the inclined web members of the inverted trapezoidal structure can more effectively resist the lateral loads (the impact of sea waves), and transfer the horizontal force to the foundation through the axial tension and compression of the members, improving the overall lateral stiffness of the structure. In addition, the inverted trapezoidal structure can leave more space at the lower part while meeting the bearing requirements, facilitating the placement of the equipment below. Facilities such as cables can be arranged. And on the premise of meeting the same bearing capacity and use functions, due to the more reasonable force, the inverted trapezoidal structure can appropriately reduce the material consumption. By optimizing the member sizes and arrangements, the cost can be reduced while ensuring the structural safety, which has more economic advantages. Setting the first support rod 312 and the second support rod 313 can effectively convert the vertical load into axial force and transfer it to the support, reducing the moment of the members, enabling the material to give full play to its strength performance and improving the overall bearing efficiency of the structure. Setting the first support cross bar 314 further enhances the axial bearing capacity, and setting the second support cross bar 315 and the third support rod 316 further enhances the lateral bearing capacity.

[0034] In this embodiment, the space truss 310 is rectangular. The first support cross bar 314 and the second support cross bar 315 are added on the left and right sides based on the Warren truss, and the upper and lower sides are improved Warren trusses, that is, the third support rod 316 is added on the basis of the Warren truss. At the same time, in order to facilitate the overall equipment to float on the sea surface, lightweight materials such as aluminum alloy can be used for the space truss 310.

[0035] The working principle of a deep-sea aquaculture device in this embodiment is as follows: When using the aquaculture equipment 100 for offshore aquaculture, the buoyancy buffer device 200 floats the entire aquaculture equipment 100 on the sea surface. When encountering wind and waves, the floating board 400 transfers the external force received to the buffer frame assembly 300 for buffering. The buffer frame assembly 300 dilutes the external force to avoid transferring the external force to the aquaculture equipment 100, and at the same time enables the entire equipment to float stably on the sea surface, with good wind and wave resistance. The buffer frame assembly 300 is set as a space truss 310, a fixing frame 320, an elastic buffer assembly 330, and several damping assemblies 340. The good wind and wave resistance of the space truss 310 is used for buffering. However, the internal connection of the space truss 310 itself is rigid, with high sensitivity and also a tolerance limit. When the wind and waves are large, the space truss 310 is prone to falling apart. Therefore, one end of the space truss 310 is connected to the fixing frame 320 to make the space truss 310 have a fixed shape, and the other end of the space truss 310 is connected to the elastic buffer assembly 330. The elastic component 331 vibrates when encountering wind and waves, and the received vibration is consumed by the balance buffer component 332. At the same time, when vibrating, the damping assembly 340 provides resistance to prevent large vibrations in the middle section of the space truss 310, making the external force generated by the wind and waves on the space truss 310 tend to be stable, and then restoring the overall structure of the space truss 310 through the elastic component 331, thereby further improving the overall tolerance limit of the buffer frame assembly 300. The floating board 400 is used to stably float the entire equipment on the sea surface. By setting the buoyancy buffer device 200, the external force of the wind and waves is diluted. The good wind and wave resistance of the space truss 310 is used for buffering in the buoyancy buffer device 200, and by connecting the space truss 310 with the fixing frame 320, the elastic buffer assembly 330, and several damping assemblies 340, the overall tolerance limit of the buffer frame assembly 300 is improved, avoiding the influence of the external force of the wind and waves on the aquaculture equipment 100, and enabling the entire equipment to have good wind and wave resistance.

[0036] Embodiment 2 This embodiment is the second embodiment of the deep - sea and far - sea aquaculture equipment. This embodiment is similar to Embodiment 1, the difference is that, as Figure 9 shown, it further includes a power mechanism 600. The power mechanism 600 includes a horizontal propeller 610, a vertical propeller 620, and a steering gear 630. The horizontal propeller 610 and the vertical propeller 620 are respectively connected to the aquaculture equipment 100 through the steering gear 630. By setting the power mechanism 600, in extremely bad weather conditions, the steering gear 630 is started to adjust the horizontal propeller 610 and the vertical propeller 620 to appropriate angles, and the horizontal propeller 610 and the vertical propeller 620 are started to resist the sea waves, thereby further enhancing the overall wind and wave resistance of the equipment.

[0037] In this embodiment, there are four horizontal propellers 610, and the four horizontal propellers 610 are respectively installed on the side of the aquaculture device 100. By changing the rotation direction of the horizontal propellers 610, upward or downward thrust can be generated on the aquaculture device 100, so as to realize the ascent or descent of the device in the vertical direction. There are six vertical propellers 620. Two vertical propellers 620 are installed between 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 aquaculture device 100, and the four vertical propellers 620 are inclined. By changing the rotation direction of the vertical propellers 620, the horizontal component forces in different directions generated by their inclined installation can be used to realize the forward and backward movement of the device, and at the same time, turning can be realized by the difference in the thrust of the propellers on the left and right sides.

[0038] Embodiment III This embodiment is the third embodiment of the deep-sea and far-sea aquaculture device. This embodiment is similar to Embodiment I, the difference being that, as Figure 2 shown, the buoyancy buffer device 200 further includes an angle adjustment mechanism 500. As Figure 3 and Figure 5 shown, the floating board 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, and the two floating blocks 420 are respectively connected to the space truss 310 through the angle adjustment mechanism 500; as Figure 3 shown, the angle adjustment mechanism 500 includes a connecting rod 510 and an electric drive joint 520. The two ends of the connecting rod 510 are respectively connected to the floating block 420 and the space truss 310 through the electric drive joint 520. When the device needs to further improve the anti-overturning performance, the electric drive joint 520 is started. The electric drive joint 520 is a common electric drive joint on the market that can be electrically driven to rotate. The electric drive joint 520 drives the connecting rod 510 to rotate, expands the distance between the two floating blocks 420, moves the whole space truss 310 downward towards the water surface, and makes the overall center of gravity of the device closer to the water surface, so as to improve the anti-wind and wave ability. In this embodiment, the floating block 420 uses a large-sized high-strength floating block, and the telescopic rod 410 uses a three-stage nested hydraulic drive structure, which can provide a thrust of up to 10 KN.

[0039] In this embodiment, floating plates 400 are provided at both ends of the space truss 310. There are four sets of angle adjustment mechanisms 500 at one end. The space truss 310 is connected to a support frame. One ends of the four sets of angle adjustment mechanisms 500 are respectively connected to the four corners of the support frame. 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 the two sets of angle adjustment mechanisms 500 are connected to the floating blocks 420 on the other side. A signal receiving antenna and a signal converter are also provided on the support frame. When it is necessary to control the electric drive joint 520, a signal can be emitted. After the signal receiving antenna receives the signal, the received electromagnetic wave signal is converted into an electric signal with a certain frequency through the signal converter, so as to realize the remote control of the electric drive joint 520.

[0040] As Figure 10 shown, the aquaculture 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. Both 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 lift between the support platform 110 and the equipment platform 120, the center of gravity height of the aquaculture equipment 100 is adjusted, thereby further enhancing the overall wave resistance of the equipment. In this embodiment, the lifting and weight adjustment device 130 includes a lifting mechanism and a load storage body. An installation opening is provided on the second platform 121. The lifting mechanism is installed at the installation opening. The load storage body is connected to the output end of the lifting mechanism. The lifting mechanism uses a commonly used lifting mechanism on the market. Sandbags or oil drums can be filled in the load storage body as needed to adjust the weight. By controlling the lifting height of the lifting device, the relative position between the load storage body and the equipment surface is changed, so as to adjust the center of gravity distribution of the equipment and effectively improve the anti-overturning performance of the equipment.

[0041] As Figure 10As shown in the figure, the equipment platform 120 includes a second platform 121, an intelligent control center 122, an energy supply system 123, a lifting bait feeding device 124, and a robotic arm clamping device 125, all of which are provided on the second platform 121. The buoyancy buffer device 200, the energy supply system 123, the lifting bait 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 bait 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 organisms in the aquaculture area are fed through the lifting bait feeding device 124, and the items on the sea surface can be clamped through the robotic arm clamping device 125. In this embodiment, the intelligent control center 122 includes an intelligent control console, a water quality sensor, an underwater camera, and a water quality oxygen content sensor. The intelligent control console controls the equipment. The water quality sensor, the underwater camera, and the water quality oxygen content sensor collect underwater environment data in real time, such as key indicators such as water temperature, salinity, pH value, and dissolved oxygen concentration. Other sensors can also be set to collect underwater environment data, which is beneficial to ensuring the quality of seawater aquaculture, improving the aquaculture efficiency, and reducing the aquaculture cost to a certain extent. The energy supply system 123 uses solar photovoltaic panels to supply power to the equipment using solar energy. The lifting bait feeding device 124 uses a spiral gravity conveying mechanism to accurately control the feeding of bait. The robotic arm clamping device 125 includes a robotic arm and a gripper. The position of the gripper is controlled by the robotic arm, and then the item is clamped by the gripper, enabling the clamping and transportation of objects.

[0042] As Figure 6As shown in the figure, the support platform 110 includes a first platform 111, a magnetic adsorption and delivery device 112 and a ballast water tank device 113 both arranged on the first platform 111. The magnetic adsorption and delivery device 112 and the ballast water tank device 113 are both communicatively connected to the intelligent control center 122, and the magnetic adsorption and delivery device 112 and the ballast water tank device 113 are both electrically connected to the energy supply system 123. By providing the ballast water tank device 113, the overall height of the device in the deep sea can be changed, enabling the overall device to float and sink in the deep sea; by providing the magnetic adsorption and delivery device 112, an underwater robot can be delivered. In this embodiment, the magnetic adsorption and delivery device 112 includes a mounting plate and an electromagnet. When the electromagnet is energized, the electromagnet can adsorb the underwater robot. When the electromagnet is de-energized, the electromagnet loses its magnetism and separates from the underwater robot, enabling the delivery of the underwater robot. The ballast water tank device 113 includes a water injection tank, an intake valve, a drainage valve and a ballast water pump. By turning on the ballast water pump and controlling the intake valve and the drainage valve, the water volume in the water injection tank is adjusted, thereby adjusting the lifting height of the device in seawater, further enhancing the anti-overturning performance of the device and enabling it to operate more stably and safely in the complex open sea environment.
