Description

Technical Field

[0001] The present invention relates to a ship-shaped net cage system in the technical field of marine aquaculture, in particular to a stepped ship-shaped net cage system. Background Art

[0002] In recent years, my country has increasingly focused on marine resources, with particular emphasis on the importance of building marine ecological pastures and realizing a "blue granary." As a key application in marine aquaculture, ship-type cage systems play a significant role in the utilization of marine resources.

[0003] In actual use of the ship-shaped cage system in marine areas, when water flows through the bow system, the water flow rate of the water flow part that is blocked by the bow system will be significantly reduced compared to the initial flow rate. However, the water flow part of the space below the bow system has not been blocked by the bow system, so the water flow rate does not drop much compared to the initial flow rate, resulting in a significant speed difference between the two parts of the water flow. Considering that the flow rate of the liquid is inversely proportional to the pressure, and the liquid always flows from the area with high pressure to the area with low pressure, that is, from the back of the bow to the bottom of the bow, turbulence will occur at the interface between the two parts of the water flow. The farther away from the bow system, the greater the range of the turbulence diffusion phenomenon. The impact of the uncertain direction of turbulence on the aquaculture of the ship-shaped cage system cannot be ignored.

[0004] However, the above-mentioned unfavorable factors have not been fully considered in the system design of the traditional ship-shaped cage system. In order to maximize the volume of the aquaculture area of ​​the ship-shaped cage system, the aquaculture depths of different square cage aquaculture areas are kept consistent, resulting in serious turbulence at the bottom of the square cage aquaculture area at the far end of the bow system, and the aquaculture effect is not ideal.

[0005] Therefore, the applicant proposed the present invention. Summary of the Invention

[0006] The purpose of the present invention is to solve the shortcomings of the above-mentioned existing technologies and fully consider the factors that affect the aquaculture of ship-type cage systems, such as turbulence caused by different flow rates and the diffusion range of turbulence is proportional to the distance, and a stepped ship-type cage system is designed.

[0007] In order to achieve the above-mentioned purpose, the present invention designs a stepped ship-shaped cage system, which includes a square frame system, a net system, a counterweight system and a single-point mooring system, wherein:

[0008] A bow system is provided on the flow-facing side of the square frame system, and the two are arranged in a line and fixed to each other; the bow system is provided with a structure for blocking the water flowing through the bow system;

[0009] The square frame system is divided into a plurality of square frame units; the net system corresponding to each square frame unit forms an independent square cage culture area, and the depth of all square cage culture areas decreases step by step from the proximal end to the distal end of the bow system;

[0010] The weight system is connected to the bottom of the net system and distributed along the outer contour of the net system;

[0011] The single point mooring system is located on the flow side of the bow system and is interconnected with the bow system.

[0012] The ship-shaped cage system of the present invention fully considers the turbulence caused by different flow rates and the fact that the diffusion range of turbulence is proportional to the distance in its system design. The depth of the square cage aquaculture area is designed to be smaller as it is farther away from the bow system (where turbulence occurs), thereby minimizing the impact of turbulence diffusion on cage aquaculture and improving the aquaculture effect of the ship-shaped cage system.

[0013] In addition, the system is designed so that water can flow through the bow system and into the net system, carrying away the excrement and residual bait produced by the farmed organisms (fish, shrimp, crabs and other marine aquatic products) in the net system, and bringing in new nutrients; at the same time, the bow system is provided with a structure for blocking the water flow passing through the bow system, so as to control the flow rate of the water after passing through the bow system, thereby maintaining a flow rate suitable for the survival of the farmed organisms.

[0014] Preferably, in the structure of the above-mentioned stepped ship-shaped cage system, the depth of the square cage breeding area near the bow system is close to the draft depth d of the bow system; and the depth of the square cage breeding area far from the bow system is close to d / 2.

[0015] The above-mentioned preferred technical solution can avoid the impact of turbulent diffusion on the aquaculture areas of different square cages to the greatest extent, and at the same time the volume of the aquaculture areas of different square cages in the ship-shaped cage system can be maximized.

[0016] In the above-mentioned stepped ship-shaped cage system, the structure on the bow system for blocking the water flow passing through the bow system preferably includes: an impeller device;

[0017] A channel 1 is formed on the main body of the bow system to pass through the upstream side and the downstream side of the main body. The impeller device is installed in the channel 1, and the impeller assembly of the impeller device is driven by the water flowing through the channel 1 to rotate.

[0018] Furthermore, the impeller device is preferably selected to include an S-shaped impeller assembly and a screw clamping mechanism for controlling the S-shaped impeller assembly to switch between self-rotation and locking states.

[0019] The baffle structure in the above-mentioned preferred technical solution adopts an impeller device, which can not only block the flow and reduce waves, but also collect part of the mechanical energy (kinetic energy, potential energy, etc. of the water flow) and convert it into electrical energy by adding a power generation system, so as to facilitate the ship-type cage system to achieve self-power supply and achieve the purpose of energy conservation and emission reduction.

[0020] The screw clamping mechanism also controls the S-shaped impeller assembly's rotational / locked switching to adapt to varying sea conditions. For example, in rough sea conditions with high sea velocity, the screw clamping mechanism can lock the S-shaped impeller assembly, stopping its rotation and increasing the bow system's overall wave and current reduction capabilities.

[0021] Furthermore, in the structure of the stepped ship-shaped cage system, the structure on the bow system for blocking the water flow passing through the bow system is preferably selected to include: a guide plate and a push rod or a cylinder;

[0022] The deflector is located on the flow-facing side of channel one, and is hinged to a pair of hinged arms extending outward from the main body through a hinge shaft, and becomes the outward extension of channel one. The push rod or cylinder one is hinged to the main body and is transmission-connected to the deflector to drive the deflector to rotate around the hinge shaft to change the angle between the guide surface of the deflector and the bottom surface of channel one, thereby increasing the openness of the opening of channel one by increasing the angle.

[0023] The guide plate in the above-mentioned preferred technical solution can change the angle between the guide surface of the guide plate and the bottom surface of channel one by rotating, thereby increasing the angle to increase the opening degree of channel one, and vice versa. Therefore, when the ship-shaped cage system is normally on the sea surface, with small winds and waves and low water flow velocity, by increasing the opening degree of channel one, the frontal area of ​​channel one can be increased, playing a flow collection role, improving the power generation efficiency of the impeller device, and generating more electricity; conversely, when the winds and waves are relatively strong at sea, by reducing the opening degree of channel one, the frontal area of ​​channel one can be reduced, playing a flow reduction role.

[0024] Furthermore, in the above-mentioned stepped ship-shaped cage system, the structure of the bow system for blocking the water flow passing through the bow system is preferably selected to include: a flow reducing plate and a push rod or a cylinder;

[0025] Channel 2 is formed on the main body of the bow system and is located on both sides of channel 1, and is also used to penetrate the upstream side and the downstream side of the main body. The flow reducing plate is located in channel 2, and a hinged seat is formed on the flow reducing plate. The push rod or cylinder 2 is hinged to the main body, and the end of the transmission rod of the push rod or cylinder 2 forms a hinged head and is transmission-connected to the hinged seat of the flow reducing plate, so as to drive the flow reducing plate to rotate around the hinge center to change the actual water flow path size of channel 2.

[0026] The flow reducing plate in the above-mentioned preferred technical solution can change the actual water flow path size of channel two by rotating, so as to further facilitate the adjustment of the bow system's flow blocking and wave reduction capabilities according to different actual sea conditions (wind and waves, water flow size, etc.).

[0027] At the same time, in order to prevent large-scale floating objects in the water flow (such as water plants, plastic garbage, etc.) from adhering to the flow-reducing plate or the net system after passing through channel two, thereby increasing the difficulty of cleaning the ship-type cage system, the above-mentioned stepped ship-type cage system has a structure in which the opening of channel two facing the upstream side is provided with an interception net, and large-scale floating objects in the water flow will be caught by the interception net before flowing through channel two.

[0028] At the same time, in order to improve the anti-tilt performance of the bow system, that is, to improve the working stability of the bow system, the above-mentioned stepped ship-shaped cage system has a structure in which anti-roll plates extending outward are formed on both sides of the main body of the bow system.

[0029] Compared with the prior art, the stepped ship-shaped cage system obtained by the present invention has the following technical effects:

[0030] The ship-shaped cage system of the present invention fully considers the turbulence generated by different flow rates and the fact that the diffusion range of turbulence is proportional to the distance in its system design. The depth of the square cage aquaculture area is designed to be smaller as it is farther away from the bow system (where turbulence occurs), thereby minimizing the impact of turbulence diffusion on cage aquaculture.

[0031] The ship-shaped cage system of the present invention is designed so that water can flow through the bow system and into the net system, carrying away the excrement and residual bait produced by the cultured organisms (fish, shrimp, crab and other marine aquatic products) in the net system and bringing in new nutrients; at the same time, the bow system is provided with a structure for blocking the water flow through the bow system, so as to control the flow velocity of the water after passing through the bow system, thereby maintaining a flow velocity suitable for the survival of the cultured organisms.

[0032] The bow system of the present invention not only blocks current and reduces waves, but also collects mechanical energy (kinetic and potential energy of the water) and converts it into electrical energy through the addition of a power generation system. This facilitates self-powering the ship-shaped cage system, achieving energy conservation and emission reduction. Furthermore, the system can adaptively adjust energy capture efficiency based on real-time sea conditions to meet the flow field requirements for cage aquaculture.

[0033] The ship-shaped cage system of the present invention has an overall flow blocking and wave reduction performance of the bow system that can be adaptively adjusted according to different real-time sea conditions, thereby achieving excellent flow blocking and wave reduction effects.

[0034] The ship-shaped cage system of the present invention has a reasonable structural design and is also capable of intercepting large-area floating objects in the water flow and preventing the bow system from tilting. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention are within the scope of protection of the present invention.

[0044] like Figure 1-7 As shown, as an embodiment of the present invention, a stepped ship-shaped cage system provided in this embodiment includes a square frame system 1, a net system 2, a counterweight system 3 and a single-point mooring system 4, wherein:

[0045] A bow system 5 is provided on the upstream side of the square frame system 1, and the two are arranged in a line and fixed to each other; the bow system 5 is provided with a structure for blocking the water flowing through the bow system 5;

[0046] The square frame system 1 is divided into a plurality of square frame units; the net system 2 corresponding to each square frame unit forms an independent square cage aquaculture area, and the depth of all square cage aquaculture areas decreases step by step from the proximal end to the distal end of the bow system 5;

[0047] The weight system 3 is connected to the bottom of the net system 2 and is distributed along the outer contour of the net system 2;

[0048] The single point mooring system 4 is located on the upstream side of the bow system 5 and is interconnected with the bow system 5 .

[0049] In this embodiment, the structure of the bow system 5 for blocking the water flow passing through the bow system 5 includes: an impeller device 6;

[0050] A channel 5-2 is formed on the main body 5-1 of the bow system 5 to pass through the upstream side and the downstream side of the main body 5-1. The impeller device 6 is installed in the channel 5-2. The impeller assembly of the impeller device 6 is driven by the water flowing through the channel 5-2 to rotate.

[0051] The impeller device 6 includes an S-shaped impeller assembly 6-1 and a screw clamping mechanism 6-2 for controlling the S-shaped impeller assembly 6-1 to switch between self-rotation and locking states.

[0052] Guide plate 7 and push rod or cylinder 8;

[0053] The deflector 7 is located on the upstream side of the channel 5-2, and is hinged to a pair of hinged arms 10 extending outward from the main body 5-1 through a hinge shaft 9, and becomes the outward extension of the channel 5-2. The push rod or cylinder 8 is hinged to the main body 5-1 and is in transmission connection with the deflector 7, so as to drive the deflector 7 to rotate around the hinge shaft 9 to change the angle between the guide surface of the deflector 7 and the bottom surface of the channel 5-2, thereby increasing the opening of the channel 5-2 by increasing the angle.

[0054] and, a flow reducing plate 11 and a push rod or cylinder 2 12;

[0055] A channel 2 5-3 is formed on the main body 5-1 of the bow system 5 and is located on both sides of the channel 1 5-2, and is also used to penetrate the upstream side and the downstream side of the main body 5-1. The flow reducing plate 11 is located in the channel 2 5-3, and a hinged seat 11-1 is formed on the flow reducing plate 11. The push rod or cylinder 2 12 is hinged to the main body 5-1, and the transmission rod end of the push rod or cylinder 2 12 forms a hinged head 12-1, and is transmission-connected to the hinged seat 11-1 of the flow reducing plate 11, so as to drive the flow reducing plate 11 to rotate around the hinge center to change the actual water flow path size of the channel 2 5-3.

[0056] The above-mentioned flow-blocking structure adopts an impeller device 6, which can not only block the flow and reduce waves, but also collect part of the mechanical energy (kinetic energy, potential energy, etc. of the water flow) and convert it into electrical energy by adding a power generation system, so as to facilitate the ship-type cage system to achieve self-power supply and achieve the purpose of energy saving and emission reduction.

[0057] At the same time, the screw clamping mechanism 6-2 controls the S-shaped impeller assembly 6-1 to switch between rotating and locking states, facilitating adaptation to varying sea conditions. For example, in rough sea conditions with high sea velocity, the screw clamping mechanism 6-2 can lock the S-shaped impeller assembly 6-1, stopping its rotation and enhancing the overall wave and current reduction capabilities of the bow system 5.

[0058] The deflector plate 7 in the above-mentioned flow-blocking structure can change the angle between the deflector surface of the deflector plate 7 and the bottom surface of the channel 1 5-2 by rotating. By increasing the angle, the opening of the channel 1 5-2 is increased, and vice versa. Therefore, when the ship-shaped cage system is normally on the sea surface, with small winds and waves and low water flow velocity, by increasing the opening of the channel 1 5-2, the flow area of ​​the channel 1 5-2 can be increased, playing a flow collection role, improving the power generation efficiency of the impeller device 6, and generating more electricity. Conversely, when the winds and waves are relatively strong at sea, by reducing the opening of the channel 1 5-2, the flow area of ​​the channel 1 5-2 can be reduced, playing a flow reduction role.

[0059] The flow reducing plate 11 in the above-mentioned flow-blocking structure can change the actual water flow path size of channel 2 5-3 by rotating, so as to further facilitate the adjustment of the flow-blocking and wave-reducing capabilities of the bow system 5 according to different actual sea conditions (wind and waves, water flow size, etc.).

[0060] In this embodiment, the depth of the square cage aquaculture area near the bow system 5 is close to the draft d of the bow system 5; while the depth of the square cage aquaculture area far from the bow system 5 is close to d / 2. This design minimizes the impact of turbulent diffusion on the different square cage aquaculture areas while maximizing the volume of the different square cage aquaculture areas in the ship-shaped cage system.

[0061] At the same time, in order to prevent large-scale floating objects in the water flow (such as water plants, plastic garbage, etc.) from adhering to the flow reduction plate 11 or the net system 2 after passing through channel 2 5-3, thereby increasing the difficulty of cleaning the ship-type cage system, the opening of channel 2 5-3 facing the upstream side is provided with an interception net 13 in this embodiment, and large-scale floating objects in the water flow will be caught by the interception net 13 before flowing through channel 2 5-3.

[0062] At the same time, in order to improve the anti-tilting performance of the bow system 5, that is, to improve the working stability of the bow system 5, anti-roll plates 14 extending outward are formed on both sides of the main body 5-1 of the bow system 5 in this embodiment.

[0063] The ship-shaped cage system provided in this embodiment has a system design that fully considers the turbulence caused by different flow rates and the fact that the diffusion range of the turbulence is proportional to the distance. The depth of the square cage aquaculture area is designed to be smaller as it is farther away from the bow system 5 (where the turbulence occurs), thereby minimizing the impact of turbulence diffusion on cage aquaculture.

[0064] In addition, the system is designed so that water can flow through the bow system 5 and toward the net system 2, carrying away the excrement and residual bait produced by the farmed organisms (fish, shrimp, crabs and other marine aquatic products) in the net system 2 and bringing in new nutrients; at the same time, the bow system 5 is provided with a structure for blocking the water flow passing through the bow system 5, so as to control the flow rate of the water after passing through the bow system 5, thereby maintaining a flow rate suitable for the survival of the farmed organisms.

[0065] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that is the same or similar to that of the present application falls within the scope of protection of the present invention.
