Abstract
Description
Technical Field
[0001] This invention relates to the field of fishery engineering equipment, specifically to a scallop cage cleaning device based on a layered circular roller brush, and also to the application of the device in cleaning scallop cages for raft-type hanging cage culture. Background Technology
[0002] Raft-type cage culture is one of the main production methods in marine ranching. It uses cages with different compartments to cultivate various types of aquatic products such as scallops, oysters, pearl oysters, and sea cucumbers. Since scallops are the primary species, they are generally referred to as scallop cages. During raft-type cage culture, scallop cages often become covered with a large number of fouling organisms, including barnacles, mussels, oysters, and hydroids. This leads to various adverse consequences, such as clogged mesh, poor water exchange, competition for food by fouling organisms, and the spread of diseases. Therefore, it is essential to clean and remove the fouling organisms from the scallop cages during raft-type cage culture.
[0003] For cleaning up fouling organisms attached to scallop cages, the general practice is to clean and treat the accumulated cages on shore after harvesting the farmed scallops using various methods, including piling to kill fouling organisms, sun exposure to remove them, crushing, and beating. In some cases, when farmed scallops are still inside the cages, fouling organisms are removed using manual cleaning, high-pressure water jet washing, or other methods such as friction or squeezing. However, currently, there is a lack of technology and equipment for the immediate removal of fouling organisms from farmed scallop cages at sea. Summary of the Invention
[0004] The purpose of this invention is to provide a scallop cage cleaning device and its application based on a layered circular roller brush, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a scallop cage cleaning device based on a layered circular roller brush, comprising a crane system for lifting the scallop cages; the cleaning device further comprises:
[0006] The roller brush system includes four rotating rollers, brushes fixedly mounted on the corresponding rotating rollers, a helical gear set and a drive mechanism; wherein, the four rotating rollers form a frame-shaped structure, and the four sets of brushes form a hollow circle in the center of the frame-shaped structure, the hollow circle being used to pass through the scallop cage;
[0007] And a flushing system, which is located above the roller brush system.
[0008] As a further improvement to the above scheme, each brush component is composed of several layers of uneven rubber brushes. The rubber brushes have a rod-shaped structure, and the lengths of several rubber brushes are matched with each other, gradually shortening from both ends to the middle to form a set of 1 / 4 arcs.
[0009] As a further improvement to the above scheme, the number of helical gear sets is three, and the three helical gear sets are respectively arranged between two adjacent rotating rollers.
[0010] As a further improvement to the above solution, the drive mechanism employs a rotary motor, which drives one set of helical gears and drives other rotating rollers through the transmission of other helical gear sets.
[0011] As a further improvement to the above solution, the cleaning device also includes a central shaft for supporting the corresponding rotating roller.
[0012] As a further improvement to the above solution, the rotating roller is sleeved on the central shaft through rolling bearings. The central shaft does not rotate, and the four central shafts are interconnected to form a support system.
[0013] As a further improvement to the above solution, the flushing system includes a water pump, a water supply pipe, and a spray ring.
[0014] As a further improvement to the above solution, the spray ring is evenly provided with several water outlets, and the water outlets face the scallop cage and are arranged in a ring.
[0015] As a further improvement to the above scheme, the overhead crane system includes a support frame, a winch fixedly installed on top of the support frame, and a hook mounted on the winch.
[0016] As a further improvement to the above solution, the hook, spray ring and roller brush system are arranged sequentially from top to bottom, and the central axes of the hook, spray ring and the hollow circle of the roller brush system coincide.
[0017] A method for cleaning scallop cages using the aforementioned cleaning device includes the following steps:
[0018] S1 installation and commissioning to ensure the normal operation of each subsystem;
[0019] S2 prepares for lifting and lowers the lifting component to the appropriate position;
[0020] S3 removes the scallop cage to be cleaned and transfers it to the lifting device;
[0021] S4 starts the scallop cage cleaning device. The scallop cage is slowly lifted upwards, while the roller brush system brushes the outside of the scallop cage downwards without dead angles. At the same time, the rinsing system sprays water to remove the dirt and organisms attached to the outside of the scallop cage.
[0022] S5 Once a string of scallop cages has completely passed through the rinsing system, the overall cleaning is complete, and the scallop cage cleaning device stops operating.
[0023] S6 removes the scallop cage that has been cleaned by S5 from the lifting device;
[0024] Repeat steps S2 through S6 until all scallop cages used in aquaculture production have been cleaned.
[0025] The application of the cleaning device described above in the cleaning of scallop cages used in aquatic raft-type cage aquaculture.
[0026] Compared with the prior art, the beneficial effects of the present invention are:
[0027] 1. A novel biological cleaning process for scallop cage fouling was proposed. During the slow lifting of the scallop cage, a circular layered roller brush was used to clean the scallop cage in the opposite direction of the lifting. The ingenious design ensures no dead corners throughout the process, resulting in a clean and efficient cleaning.
[0028] 2. The device consists only of a roller brush system, a flushing system, and a crane system. It has a simple and compact structure and can be used on land sites near the shore or installed on production vessels for operation at the aquaculture production site. It can efficiently remove fouling organisms and improve the efficiency of aquaculture production.
[0029] 3. Scallop cages are flexible mesh structures, lacking rigidity. Traditional cleaning methods either involve cleaning the stacked scallop cages after harvesting the farmed scallops, or fixing the cages in some way, such as stretching both ends, to maintain their cylindrical shape before cleaning. This invention innovatively proposes a new solution that eliminates the need to fix the flexible scallop cages. By slowly lifting the cages while brushing them in the opposite direction, it effectively straightens and tightens the cages, avoiding the problem of deformation that hinders effective cleaning. This is a very ingenious approach. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. It should be understood that the following description is merely illustrative and not intended to limit the invention.
[0036] The specific embodiments of the present invention will be described in detail below.
[0037] Example 1
[0038] Please see Figure 1 This embodiment provides a scallop cage cleaning device based on a layered circular roller brush, which includes a crane system for lifting the scallop cage 12, a rinsing system acting on the scallop cage 12, and a roller brush system with a virtual circle. The roller brush system, rinsing system, and crane system are assembled together to form a cleaning device with a simple and compact structure, which can be flexibly applied to different workplaces. After the entire device is installed and fixed, its overturning tensile force is not less than 400 kg.
[0039] The overhead crane system includes a support frame 9, a winch 10 fixedly installed on top of the support frame 9, and a hook 11 mounted on the winch 10. When operating on an aquaculture production vessel, the support frame 9 is fixed to the vessel; when operating on a suitable site on land, the support frame 9 is fixed in a suitable position.
[0040] The overhead crane system slowly lifts the scallop cages 12 used for aquaculture production upwards via hook 11, allowing them to pass sequentially through the hollow circle of the roller brush system and the spray ring. During this process, the roller brush system and the rinsing system are activated simultaneously, performing a bottom-up external brushing of the lifted scallop cages 12, thereby efficiently removing various marine fouling organisms attached to the exterior of the scallop cages 12. In this embodiment, the overhead crane system is installed above the roller brush system and the rinsing system. In specific implementation, the height of the overhead crane system can be adjusted appropriately according to actual needs. The winch 10 is a commercially available product with waterproof and low-speed characteristics. The operating speed of the winch 10 driving the hook 11 is no higher than 20 cm / s, and the lifting speed is adjustable. The load-bearing capacity of the hook 11 is no less than 200 kg.
[0041] The rinsing system includes a water pump 5, a water supply pipe 7, and a spray ring 6. The water pump 5 is used to draw aquaculture water from the same area as the aquaculture production area and supply it to the spray ring 6. In this embodiment, the water pump 5 is a submersible pump, and the water supply pipe 7 is a steel pipe, which provides a certain degree of support for the spray ring 6. In actual design, an auxiliary frame can also be added to the water supply pipe 7 to improve the stability of the rinsing system, which will not be elaborated here.
[0042] The hook 11, spray ring 6, and roller brush system are arranged sequentially from top to bottom, and the central axes of the hook 11, spray ring 6, and the hollow circle of the roller brush system coincide. In this embodiment, when the crane system slowly lifts the scallop cage 12 upwards, the roller brush system rolls downwards to brush the scallop cage 12, and at the same time pulls the scallop cage 12 downwards. The rinsing system sprays water to rinse the scallop cage 12 simultaneously. When the crane system completely removes the scallop cage 12 from the spray ring 6, the cleaning of one scallop cage 12 is completed.
[0043] The spray ring 6 has several water outlets evenly distributed around it, with the outlets facing the scallop cage 12. Based on the aforementioned design, the water delivered by the spray ring 6 can be evenly sprayed at the contact point between the brush 2 and the scallop cage 12, promoting the removal of detached debris.
[0044] The roller brush system includes four rotating rollers 1, brush pieces 2 fixedly mounted on the corresponding rotating rollers 1, helical gear sets 3, and a drive mechanism 4. The four rotating rollers 1 form a frame-like structure, and the four brush pieces 2 form a hollow circle in the center of the frame. There are three helical gear sets 3, each positioned between two adjacent rotating rollers 1. The drive mechanism 4 uses a rotary motor to drive one of the helical gear sets 3, and through the other helical gear sets 3, drives the other rotating rollers 1.
[0045] In this embodiment, the four brushes 2 form a virtual hollow circle in the center of the frame formed by the four rotating rollers 1, allowing for rolling brushing of cylindrical objects, i.e., scallop cages 12. The specific process is as follows: the four rotating rollers 1 are driven by interconnected helical gear sets 3. A rotary motor drives a helical gear set 3, which, under the action of meshing transmission, drives the brushes 2 to rotate. Please refer to the relevant documentation. Figure 2 The four brushes 2 rotate in the direction of rotation from the outside to the inside of the roller when viewed from above. They cannot rotate in the opposite direction. That is, the direction of the brushes 2 rolling and brushing is downward, while the direction of the scallop cage 12 lifting and moving is upward, ensuring that the two directions are opposite.
[0046] Each brush component 2 consists of several layers of uneven rubber brushes. The rubber brushes have a rod-shaped structure, and the lengths of several rubber brushes are matched with each other, gradually shortening from both ends to the middle to form a set of 1 / 4 arc shapes. In this embodiment, the brush component 2 is made of wear-resistant rubber material made of polyurethane or other polymer materials, which gives the brush component 2 high strength and toughness, and makes it resistant to cutting by marine fouling organisms such as oysters and barnacles attached to the scallop cage 12.
[0047] In this embodiment, while the roller brush system is rolling and brushing the scallop cage 12, spraying is applied to the contact area between the brush 2 and the scallop cage 12. This not only promotes the removal of the brushed debris, but also increases the lubrication at the contact area between the brush 2 and the scallop cage 12, preventing it from being a completely dry friction and thus reducing the wear and tear on the scallop cage 12 and the brush 2.
[0048] Unlike static brushing, where brush 2 rotates in a fixed position and achieves a good brushing effect through contact with the rotating brush 2 as the scallop cage 12 passes by, this embodiment designs a dynamic brushing structure. This allows for excellent synergy between brushing and spray rinsing, solving the problems of weak cleaning power, blind spots on uneven surfaces, and significant unilateral deformation and wear of brush 2 caused by static friction brushing. Furthermore, the scrubbing force generated by the rolling of brush 2, along with the centrifugal self-cleaning and spray rinsing during its rotation, ensures that brush 2 remains relatively clean, improving brushing uniformity and cleaning efficiency while reducing wear.
[0049] The cleaning device also includes a central shaft 8 for supporting the corresponding rotating roller 1. The rotating roller 1 is mounted on the central shaft 8 via rolling bearings. The central shaft 8 does not rotate, and the four central shafts 8 are interconnected to form a support system. To fix the roller brush system at a certain height and improve the stability of its roller brush operation, the four central shafts 8 are interconnected to form a support system, which is also equipped with a load-bearing frame. The load-bearing frame is used to support the central shaft 8. In actual design, the load-bearing frame can be fixed on the operating vessel.
[0050] In practical design, four sets of I-shaped mesh protective covers can be installed on the outside of the roller brush system. The openings of the I-shaped mesh protective covers face the virtual hollow circle inside the roller brush system, thus preserving space in the center for the scallop cage to pass through. The protective covers prevent the splashing of brush-shedding materials and also prevent accidental injury to operators from the roller brush system. The bottom of the protective covers is tilted at an angle of more than 20° to facilitate the sliding of brush-shedding materials, which will not be elaborated further here.
[0051] Example 2
[0052] This embodiment provides a method for cleaning scallop cages using a cleaning device as described in Embodiment 1, which includes the following steps:
[0053] S1 is used to install, debug, and configure the control system to ensure the normal operation of each subsystem.
[0054] The operation of S2 winch 10 causes hook 11 to descend, and hook 11 passes sequentially through spray ring 6 and the center of roller brush system until it descends to a suitable position.
[0055] S3 removes the scallop cage 12 from the aquaculture production and transfers it from the aquaculture production floating stalk or other location to the hook 11;
[0056] When S4 starts the scallop cage cleaning device, the winch 10 slowly lifts the scallop cage 12 upwards, while the roller brush system brushes the outside of the scallop cage 12 downwards without dead angles. At the same time, the rinsing system sprays water to efficiently remove all attached dirt and organisms from the outside of the scallop cage 12.
[0057] S5 Once a string of scallop cages 12 has completely passed through the rinsing system, the overall cleaning is complete, and the operation of the scallop cage cleaning device is stopped.
[0058] S6 removes the scallop cage 12, which has been cleaned by S5, from the hook 11 and resuspends it on the floating stem for continued cultivation or other processes of cultivation production;
[0059] Repeat steps S2 through S6 until all scallop cages 12 used in aquaculture production have been cleaned.
[0060] Example 3
[0061] This embodiment provides the application of a scallop cage cleaning device based on a layered circular roller brush, as described in Embodiment 1, in the cleaning of scallop cages for aquaculture using a raft-type suspended cage system. In application, the cleaning device is installed at a certain distance from the outer side of the aquaculture vessel using appropriate counterweights and fixing methods. After installation and fixing, the overall device has an anti-overturning tensile strength of no less than 400 kg. Using the operating steps based on Embodiment 2, scallop cages 12 can be easily lifted one by one from the aquaculture area, and simultaneously brushed to remove fouling organisms. If necessary, multiple cleaning devices can be installed side-by-side on both sides of the aquaculture vessel to simultaneously brush multiple scallop cages 12 on-board. After cleaning, the scallop cages can continue to be suspended under the aquaculture raft for aquaculture production. Because the permeability of the scallop cages is greatly increased after removing fouling organisms, and the risk of fouling organisms competing for food and spreading diseases is reduced, the effectiveness and efficiency of aquaculture production are greatly improved.
[0062] Example 4
[0063] This embodiment provides the application of a scallop cage cleaning device based on a layered circular roller brush, as described in Embodiment 1, in the cleaning of scallop cages for aquaculture using raft-type hanging cages. The difference between this embodiment and Embodiment 3 is that, in this application, the entire cleaning device is installed at the land-based work site on the shore using appropriate counterweights and fixing methods. Following the operating steps of Embodiment 2, the harvested scallop cages 12 piled up at the site are suspended one by one on hooks 11. The scallop cages 12 are then lifted and simultaneously brushed to remove fouling organisms from their exterior. If necessary, multiple cleaning devices can be installed at the land-based work site to efficiently brush multiple scallop cages 12 simultaneously. The cleaned scallop cages 12 are then transported to the aquaculture waters for continued aquaculture production or used in other production processes. The cleaned scallop cages can continue to be suspended under the aquaculture raft for aquaculture production. Because the permeability of the scallop cages is greatly increased after removing fouling organisms, and the risk of fouling organisms competing for food and spreading diseases is reduced, the effectiveness and efficiency of aquaculture production are greatly improved.
[0064] The above embodiments are merely preferred embodiments of the present invention. Any simple modifications, alterations, and substitutions made to the above embodiments based on the technical essence of the present invention shall fall within the scope of the technical solution of the present invention.
