Description

Technical Field

[0001] The present invention relates to the field of deep-water cages, and in particular to a device for cleaning biological attachments around deep-water cages. Background Art

[0002] As the aquaculture industry expands into the deep sea, deep-water cages have become a key development focus of the industry due to their large aquaculture capacity and strong resistance to wind and waves. However, the cages are immersed in water for a long time, and organisms such as barnacles, algae, and mussels are very likely to attach to the surface of the net. These attached organisms will not only clog the mesh, reducing the water exchange efficiency of the cage by 30%-70%, resulting in insufficient dissolved oxygen and accumulation of metabolic waste in the cage, but also increase the weight and resistance of the cage, aggravate the wear of the net, and shorten the service life of the equipment.

[0003] At present, the cleaning of biological attachments in deep-water cages mainly relies on manual diving cleaning or high-pressure water gun flushing. Manual cleaning is inefficient, labor-intensive, and poses a diving safety risk. Although high-pressure water guns can achieve remote cleaning, they have high energy consumption and a large impact on the net, which can easily cause damage to the net. In addition, when stubborn attached organisms (such as adult barnacles) are attached to the net, staff are required to dismantle the net and dry it in the sun to dehydrate the attached organisms, thereby facilitating cleaning and further reducing the working efficiency of deep-water cages. Therefore, there is an urgent need to develop a new cleaning device that can reduce damage to the net while ensuring the cleaning effect, thereby improving cleaning efficiency and equipment reliability.

[0034] The present invention proposes a device for cleaning biological attachments around a deep-water cage. The device cooperates with a driving component and a separation component to automatically perform periodic cleaning operations on the net 2 when the deep-water cage is working normally, thereby improving the working efficiency of the deep-water cage while ensuring the aquaculture effect. In addition, periodic cleaning can also inhibit the attachment of stubborn attached organisms, reduce the frequency of disassembly and cleaning of the net 2, and further improve the working efficiency of the deep-water cage.

[0035] Example 1

[0036] In this embodiment, the structure of the deep water cage is as follows Figures 1 to 8 As shown, it includes a floating frame 1, a net 2 and a support frame 4. The bottom end of the floating frame 1 is provided with a net 2, and the bottom end of the net 2 is provided with a support frame 4. The bottom end of the floating frame 1 is evenly provided with a plurality of first connecting rods 3. The floating frame 1 and the support frame 4 are connected by the first connecting rods 3. A connecting bar 14 is provided on one side of the floating frame 1. The floating frame 1 and the connecting bar 14 are connected by setting a driving component. Separation components are evenly provided between the connecting bar 14 and the net 2, as shown in FIG. Figure 2 and Figure 3As shown, the driving assembly includes a first rotating groove 5 arranged at the top of the floating frame 1, and a rotating plate 6 is slidably installed on the top of the first rotating groove 5, and the rotating plate 6 is fixedly installed on one side of the connecting bar 14. The top of the rotating plate 6 is fixedly installed with a first motor 7, and the first motor 7 is connected to an external power supply through a wire. The output end of the first motor 7 is fixedly installed with a second connecting rod 8, and the bottom end of the second connecting rod 8 is fixedly installed with a first driving gear 9. The second connecting rod 8 and the first driving gear 9 both slide on the inner wall of the second rotating groove 10. The second rotating groove 10 is opened at the top of the first rotating groove 5, and the inner wall of the second rotating groove 10 is evenly installed with first tooth blocks 11. The first driving gear 9 is engaged with the first tooth block 11. When the net 2 needs to be cleaned, the first motor 7 is started so that the first motor 7 drives the first driving gear through the second connecting rod 8. The wheel 9 rotates, and the first driving gear 9 continuously engages with the first tooth block 11, so that the first driving gear 9 drives the rotating plate 6 to rotate along the first rotating groove 5 through the second connecting rod 8, and the rotating plate 6 drives the separation component to move along one side of the net 2 through the connecting bar 14, thereby separating the attached organisms on the surface of the net 2. Pulleys 12 are installed at the bottom ends of both sides of the rotating plate 6, and the pulleys 12 slide on the inner wall of the slide groove 13. The slide grooves 13 are both opened on both sides of the first rotating groove 5. This design can reduce friction resistance and jamming, making the movement of the rotating plate 6 smoother and more stable, and suppressing shaking and deflection, thereby improving the separation effect of the separation component, and avoiding the rotating plate 6 driving the separation component to shake through the connecting bar 14, so that the separation component is closer to the net 2, which is easy to cause hooking and pulling on the net 2, thereby causing damage.

[0037] Furthermore, in this embodiment, Figure 2 、 Figure 4 、 Figure 5 and Figure 6As shown, the separation component includes a waterproof shell 15 on one side of the connecting strip 14, and a protective block 16 is fixedly installed at the bottom end of the waterproof shell 15, wherein the side of the protective block 16 away from the separation hook 17 is set as an arc portion. Such a design can make it possible for the driving component to drive the separation component to move, and the protective block 16 will first abut against the net 2, and push the abutting part of the net 2 inward through the end of the arc portion to prevent the separation hook 17 from passing through the mesh on the net 2, hooking and pulling the net 2, and causing damage to the net 2. A separation hook 17 is rotatably installed on one side of the protection block 16. When organisms are attached to the net 2, the attached organisms can be squeezed and pushed by the separation hook 17, forcing the attached organisms to detach from the net 2, wherein one end of the separation hook 17 is set as a curved hook, and the curved hook-shaped end can penetrate into the contact surface gap between the organism and the net 2, and use "prying" to The principle is to destroy the mechanical balance of biological attachment, which makes it easier for organisms to fall off the surface of the net 2 than the plane structure. The side close to the protective block 16 is set as an outward convex part. This design can contact the net 2 with the curved surface when pushing the organism, reduce local pressure, avoid the breakage of the net 2 fiber due to stress concentration, and further improve the protection effect of the net 2. On this basis, the separation hook 17 is fixedly installed with a first arc rod 18 on the side close to the protective block 16. The first arc rod 18 is slidably installed on the inner wall of the arc groove 19. The arc groove 19 is opened on the inner wall of the protective block 16. The end of the first arc rod 18 away from the separation hook 17 is fixedly installed with an extrusion block 20. The outer wall of the arc groove 19 is sleeved with a spring 21, and the inner wall of the separation hook 17 is rotatably installed with a rotating shaft 22. The rotating shafts 22 are all fixedly installed on the inner side of the waterproof outer shell 15, and a space for the separation hook 17 to rotate is also opened between the waterproof outer shells 15. With this design, when the separation component does not abut the attached organisms, the elastic action of the spring 21 can push the extrusion block 20 to abut one end of the arc groove 19, thereby positioning the position of the separation hook 17, avoiding the separation hook 17 from being deflected by external forces such as water flow, affecting the abutment position of the bent hook end of the separation hook 17 on the attached organisms, thereby affecting the separation effect of the separation hook 17, and when the separation hook 17 abuts the attached organisms, the separation hook 17 can be rotated around the rotating shaft 22 as the axis, so that the separation hook 17 moves to the weak point of the connection between the attached organisms and the net 2, thereby improving the separation effect of the separation hook 17.

[0038] To sum up, in this embodiment, the driving assembly can periodically start the first motor 7, so that the first motor 7 drives the second connecting rod 8 to rotate, and the second connecting rod 8 drives the first driving gear 9 to rotate, so that the first driving gear 9 engages and moves with the first tooth block 11, so that the first driving gear 9 drives the rotating plate 6 to rotate along the first rotating groove 5 through the second connecting rod 8, and the rotating plate 6 drives the connecting bar 14 to move, and the connecting bar 14 drives the waterproof shell 15 to rotate, and the waterproof shell 15 drives the protective block 16 and the separation hook 17 to move around the net 2. When there are attached organisms on the surface of the net 2, the separation hook 17 abuts against it and pushes it off from the surface of the net 2. An existing biological attachment cleaning device around a deep-water cage often waits until a large number of organisms are attached to the surface of the net 2 before the staff performs diving cleaning operations. This has low work efficiency and a diving hazard. , and when faced with stubborn attached organisms such as barnacles, it is necessary to take the deep-water cage out of the water and disassemble the net 2 for drying, which affects the working efficiency of the deep-water cage. After adopting the cleaning device of this embodiment, there is no need for staff to dive for cleaning, which reduces the diving risk of staff. Frequent periodic cleaning operations can also remove and separate stubborn attached organisms (such as barnacles) in the planktonic larval stage, preventing them from growing to the attached metamorphosis stage or even the adult stage, where simple cleaning measures are difficult to clean, thereby requiring the net 2 to be disassembled for complex cleaning operations, affecting the working efficiency of the deep-water cage. In addition, the cleaning component also uses the first arc rod 18, arc groove 19, extrusion block 20 and spring 21 to enable the separation hook 17 to move to the weak point of the connection between the attached organism and the net 2 when the separation component does not abut the attached organism, thereby improving the separation effect of the separation hook 17.

[0039] Example 2

[0040] In order to explain the embodiment 1, in this embodiment, Figures 5 to 7As shown, a connecting assembly is provided on one side of the separation hook 17, and the connecting assembly includes a second arc rod 23 provided on one side of the separation hook 17, and the other end of the second arc rod 23 is rotatably mounted with a first connecting rod 24, and the other end of the first connecting rod 24 away from the second arc rod 23 is rotatably mounted with a second connecting rod 25, and one end of the second connecting rod 25 is fixedly mounted with a fixed rod 26, and the inner wall of the fixed rod 26 is connected to a rotating rod 27 through a bearing, and one side of the rotating rod 27 is fixedly mounted with a first connecting block 28, and one side of the first connecting block 28 is engaged with a second connecting block 29, and the second connecting block 29 is provided with an expulsion assembly on the side away from the first connecting block 28, and the inner wall of the second connecting block 29 is rotatably mounted with a driving rod 30 One end of the driving rod 30 is fixedly mounted on the inner wall of the first connecting block 28, and the other end of the driving rod 30 is fixedly mounted with a drill bit 31. When the separation hook 17 abuts against the attached organisms and rotates, the separation hook 17 drives the fixed rod 26 to move through the second arc rod 23, the first connecting rod 24 and the second connecting rod 25, so that the fixed rod 26 drives the drill bit 31 to pierce the attached organisms through the driving rod 30, and the attached organisms are actively separated from the net 2 by mechanical damage or stimulation (such as the stress response of cnidarians), or the adhesion is reduced by physical crushing, so that the separation hook 17 can more easily separate the attached organisms from one side of the net 2, thereby improving the cleaning effect of the separation component, thereby improving the working efficiency and aquaculture effect of the deep-water cage;

[0041] Furthermore, the expulsion assembly includes a first bevel gear 32 arranged on the side of the second connecting block 29 away from the first connecting block 28, wherein the first bevel gear 32 is fixedly connected to the second connecting block 29, and the first bevel gear 32 is sleeved on the outer wall of the driving rod 30. Such an arrangement allows the driving rod 30 to move and rotate on the inner wall of the first bevel gear 32 and the second connecting block 29. In addition, the second connecting block 29 and the first bevel gear 32 are both rotatably mounted on the inner wall of the waterproof shell 15 through bearings, thereby ensuring that the second connecting block 29 and the first bevel gear 32 can only rotate and cannot move laterally. A second bevel gear 33 is meshed and installed on one side of the first bevel gear 32, and a third connecting gear 33 is fixedly mounted on the top of the second bevel gear 33. The connecting rod 34 and the top of the third connecting rod 34 are fixedly installed with a waterproof box 35, which is fixedly installed on one side of the connecting strip 14. A second motor is provided inside the waterproof box 35 (not shown in the figure. The second motor in this embodiment and the first motor 7 in the first embodiment are both LW100 models, and both belong to mature existing technologies, so their internal structures and working principles are not described in detail). By providing the waterproof box 35, the second motor can be protected to prevent the second motor from being corroded and damaged by water droplets splashed from the water surface. The second motor is connected to an external power supply through a wire. This design allows the second motor to drive the third connecting rod 34 to rotate, so that the third connecting rod 34 drives the second connecting block 29 through the second bevel gear 33 and the first bevel gear 32. Regarding rotation, it should be added that one side of the first connecting block 28 and the second connecting block 29 are both bevel teeth, and the bevel teeth are distributed in a ring array. Such a design can generate an axial component of force when the first connecting block 28 and the second connecting block 29 are engaged, so that the first connecting block 28 can be rotated to a position tightly engaged with the second connecting block 29, so that the second connecting block 29 can drive the first connecting block 28 to rotate, thereby driving the drill bit 31 to rotate through the drive rod 30, thereby improving the force effect of the drill bit 31 on the attached organisms and weakening the attachment force of the attached organisms. Furthermore, the outer wall of the drill bit 31 is provided with a thread, which can produce a shear and tearing effect on the shell or adsorption structure of soft attached organisms (such as barnacle larvae, mussels, etc.) when drilling into them, thereby destroying their tissue structure. The adhesion is directly weakened, and the penetration force of the drill bit 31 is increased. The spiral structure will generate continuous squeezing and crushing force on the biological attachment layer when rotating, making it easier for the attached organisms to be peeled off from the surface of the net 2. In addition, the friction between the thread line and the surface of the attached organism can provide a stronger gripping force, preventing the drill bit 31 from slipping due to the irregular shape of the biological shell. At the same time, the guiding property of the spiral structure can make the drill bit 31 drill in a straight line, thereby improving the cleaning accuracy. In this embodiment, the material of the drill bit 31 and the thread line is preferably high-carbon alloy steel. Compared with the commonly used stainless steel material, the high carbon content makes it naturally have high hardness. The thread can be kept sharp without complex surface treatment. The wear resistance of the cutting edge is three to five times that of stainless steel. While ensuring corrosion resistance, a certain hardness is taken into account.The cost is low. On the other hand, after the separation hook 17 pushes the attached organism away from one side of the net 2, the spring 21 releases its elastic potential energy, undergoing elastic deformation and pushing the extrusion block 20 to move. The extrusion block 20 drives the separation hook 17 to reset via the first arc rod 18, thereby driving the expulsion assembly to reset. At this time, the drill bit 31 can be easily withdrawn from the organism through the thread line, thereby separating from the organism.

[0042] To sum up, in this embodiment, by starting the second motor, the second motor drives each second bevel gear 33 to rotate through the third connecting rod 34, so that the second bevel gear 33 drives the first bevel gear 32 to rotate, and the first bevel gear 32 drives the second connecting block 29 to rotate. When the separation hook 17 abuts against the attached organisms and rotates, the separation hook 17 drives the second arc rod 23 to rotate, the second arc rod 23 drives the first connecting rod 24 to move, and the first connecting rod 24 drives the second connecting rod 25 to move, so that the second connecting rod 25 drives the fixed rod 26 to move, the fixed rod 26 drives the rotating rod 27 to move, and the rotating rod 27 drives the first connecting block 28 and The driving rod 30 moves, so that the first connecting block 28 engages with the second connecting block 29. At the same time, the driving rod 30 drives the drill bit 31 to move, so that the drill bit 31 is inserted into the attached organism. At this time, the second connecting block 29 drives the first connecting block 28 to rotate, and the first connecting block 28 drives the driving rod 30 to rotate. The driving rod 30 then drives the drill bit 31 to rotate, so that the drill bit 31 destroys the adhesion of the shell of the mollusk or stimulates the contraction of the coelenterate, thereby weakening the adhesion of the attached organism, making it easier for the separation hook 17 to perform the separation operation, and helping to improve the separation effect of the separation component, thereby improving the water flow exchange effect of the deep-water cage and improving the breeding effect of the deep-water cage.

[0043] Furthermore, in the present embodiment, a pressure sensor is provided on one side of the second arc rod 23 close to one end of the first connecting rod 24 (not shown in the figure, because it belongs to the mature existing technology, its internal structure and working principle are not described in detail). The pressure sensors are fixedly mounted on the inner wall of the waterproof shell 15. With this design, when stubborn attached organisms are attached to the surface of the net 2, the separation component is difficult to clean. At this time, the stubborn attached organisms drive the separation hook 17 to rotate, so that the separation hook 17 drives the second arc rod 23 to rotate until it abuts against the pressure sensor, or when the separation hook 17 is accidentally hooked on the mesh of the net 2, the pressure sensor can send a signal. The signal controls the first motor 7 to shut down and notifies the staff to perform precise and detailed cleaning operations or maintain the separation components to prevent the separation components from being damaged by motion interference. In addition, it is worth adding that each water-proof shell 15 is independently provided with an expulsion component, so that only when the separation hook 17 abuts against the attached organisms, the drill bit 31 in the corresponding expulsion component will rotate out to puncture the attached organisms. Compared with integrating all the expulsion components with the second motor and the third connecting rod 34, the setting in this embodiment can reduce the load of the second motor, reduce resource consumption and extend the service life of the second motor and the expulsion component.

[0044] Example 3

[0045] In this embodiment, if Figures 5 to 8As shown, an auxiliary flow guide assembly is further provided on the side of the fixed rod 26 away from the rotating rod 27. The auxiliary flow guide assembly includes a connecting plate 36 provided on one side of the fixed rod 26. A second tooth block 37 is fixedly installed on the inner side of the connecting plate 36. A driving gear rod 38 is meshed and installed on one side of the second tooth block 37. A venturi tube 39 is fixedly installed on the bottom end of the driving gear rod 38. The inner wall of the venturi tube 39 is provided with a flow guide channel, wherein the flow guide channel is divided into a contraction section where the pipe diameter gradually decreases, the flow velocity increases and the pressure decreases when the water flows through; the throat end where the pipe diameter is the narrowest, the water flow velocity is the fastest and the pressure is the lowest; and the pipe diameter gradually expands and the water flow velocity decreases. , the diffusion section where the pressure rises, the axial direction of the guide channel is the same as the tangential direction of the movement of the rotating plate 6, and the contraction section is arranged on the side of the venturi tube 39 close to the drill bit 31. With this design, when the separation hook 17 abuts against the attached organisms, the separation hook 17 drives the fixed rod 26 to move, so that the fixed rod 26 drives the connecting plate 36 to move, and the connecting plate 36 drives the second tooth block 37 to move, so that the second tooth block 37 drives the driving gear rod 38 to rotate, and the driving gear rod 38 is rotated through the venturi tube 39, so that the venturi tube 39 rotates the contraction section to a position away from the net 2 and rotates the diffusion section to a position close to the net 2. Based on the Bernoulli principle, the mutual conversion of flow rate and pressure is achieved by changing the cross-sectional area of ​​the fluid flowing through the pipeline. At this time, when the fluid flows through the Venturi tube 39, the cross-sectional area of ​​the diversion channel is first reduced and then expanded, so the flow rate of the fluid in the contraction section will increase, the pressure will decrease, and the accelerated water flow will impact the surface of the net 2, which can separate biological residues or algae, reduce blockage, and improve the local water flow exchange capacity of the net 2, thereby compensating for the water flow exchange in the local area of ​​the net 2 where the water flow exchange is reduced due to biological attachment, thereby improving the working effect of the deep-water cage. Furthermore, the number of the second tooth blocks 37 is less than a quarter of the number of teeth on the outer wall of the Venturi tube 39. One of them is that after the second tooth block 37 drives the venturi tube 39 to rotate through the driving gear rod 38, the diffusion section of the venturi tube 39 is obliquely facing the surface of the net 2. At this time, when the driving component drives the venturi tube 39 to move, the impact force of the water flow in the contraction section of the venturi tube 39 can be enhanced, thereby enhancing the suction effect of the venturi tube 39, and then enhancing the impact effect of the diffusion section, improving the local water flow exchange effect of the deep-water cage. If the venturi tube 39 is perpendicular to the surface of the net 2, it is easy to make the impact force of the diffusion section insufficient, the suction effect is weak, and the jet impacts the net 2 vertically, which is easy to form a vortex dead zone on the inside of the net 2, hindering water flow exchange.
