Description

Technical Field

[0001] The present invention relates to the technical field of cage cleaning, and in particular to a device and a method for cleaning a marine ranch aquaculture cage. Background Art

[0002] With the growing global demand for clean energy and the booming development of marine fisheries, the integration of offshore wind power and marine aquaculture is gaining increasing attention. As key facilities in this model, offshore wind power aquaculture cages face numerous challenges due to their mesh surfaces being constantly submerged in seawater.

[0003] On the one hand, seawater is rich in various plankton, algae, and microorganisms. Over time, these organisms will attach to the mesh of the aquaculture cages in large numbers. The growth of algae not only clogs the mesh, reducing the efficiency of water exchange between the inside and outside of the cages, and affecting the water quality within the aquaculture area, but also threatens the living environment of the aquacultured organisms, hindering their normal growth, and may even cause disease and reduce fishery production. The fouling layer formed by the accumulation of plankton and microorganisms also increases the weight of the mesh, increasing the overall load of the cages, negatively affecting the structural stability of the cages, and shortening their service life. On the other hand, the complex and harsh marine environment, with wind, waves, tides, and other factors constantly impacting the cages, makes the dirt attached to the mesh more stubborn and difficult to clean.

[0004] In the existing technology, cages are usually cleaned manually, which requires a lot of manpower and material resources. Operators need to go out to sea by boat and lift the cages above the sea surface, or the cleaning personnel need to dive underwater. The labor intensity is extremely high, the cleaning efficiency is low, and there are certain safety risks. Summary of the Invention

[0005] In view of this, the present invention provides a marine ranch aquaculture cage cleaning device and a cage cleaning method to solve the problem of low cleaning efficiency and safety risks in the existing manual cage cleaning method.

[0006] In the first aspect, the present invention provides a marine ranch aquaculture cage cleaning device, comprising a cage, a cleaning component and an operating table. The cage is suitable for being placed in water. The cage comprises a frame and a net. Several frames enclose a receiving cavity. The net is mounted on the frame. The cleaning component is movably mounted on the frame and abuts against the net. The cleaning component is located on the inner side of the cage. The operating table is set on the water surface. The operating table is signal-connected to the cleaning component.

[0007] Beneficial effects: The present invention movably installs the cleaning component on the frame, and controls the cleaning component to move along the inner side of the net through the operating table to brush and clean the net, thereby removing debris and dirt attached to the net. There is no need to manually clean the net, and there is no need to remove the net box from the water. It has good safety, convenient operation and high cleaning efficiency.

[0008] In an optional embodiment, the cleaning component includes a mounting frame, an impeller, a water pipe, a cleaning brush and a drive assembly. The mounting frame is located on the inner side of the mesh box, and several impellers are rotatably mounted on the mounting frame. The water pipe is installed on the mounting frame. A nozzle is provided at one end of the water pipe, and the nozzle faces the impeller. The other end of the water pipe is connected to the operating table. The cleaning brush is arranged on the side of the impeller away from the nozzle. The drive assembly is arranged on the mounting frame, the drive assembly is movably connected to the frame, and the drive assembly is connected to the operating table by signal.

[0009] Beneficial effects: The present invention outputs water to the nozzle through a water pipe. The water flow sprayed from the nozzle drives the impeller to rotate, driving the cleaning brush to rotate on the surface of the net. As the driving component moves, the surface of the net is cleaned. No manpower is required to clean the net, and no electrical equipment is set underwater, which reduces the failure rate of the device during use and ensures long-term operation of the device.

[0010] In an optional embodiment, the impellers are arranged in two rows side by side, and the impellers in the two rows rotate in opposite directions.

[0011] Beneficial effects: The present invention sets the impellers to two types with opposite rotation directions. By driving the impellers with different rotation directions to rotate, the reciprocating movement of the cleaning component can be achieved, which has the advantages of simple structure and convenient operation.

[0012] In an optional embodiment, the driving assembly includes a gear, the gear is coaxially connected to the impeller, and a rack is provided on the frame, and the gear is meshed with the rack.

[0013] Beneficial effects: The present invention adopts a gear and rack driving method with a simple structure and good stability. It does not require the installation of electrical equipment. When the impeller rotates, the gear can rotate accordingly.

[0014] In an optional embodiment, the water supply pipe includes a main line, a control valve, a first branch pipe and a second branch pipe. The control valve is arranged at the end of the main line, the control valve is connected to the operating console signal, the first branch pipe is connected to the control valve, the second branch pipe is connected to the control valve, and the first branch pipe and the second branch pipe are arranged in parallel.

[0015] Beneficial effects: The present invention drives impellers of different rows by switching the connection between the main pipe and the first branch pipe and the second branch pipe through a control valve, thereby realizing reciprocating movement of the driving assembly along the frame, with a simple structure and convenient operation.

[0016] In an optional embodiment, the cleaning component further includes a first sensor, which is disposed at both ends of the rack and is connected to the control valve signal.

[0017] Beneficial effect: The present invention sets a first sensor. When the gear moves to the end of the rack, the first sensor outputs a signal, and the control valve switches the branch pipeline connected to the main pipeline, thereby realizing the reversal of the cleaning component, which has the advantages of simple structure and convenient operation.

[0018] In an optional embodiment, the cleaning component further includes a second sensor, which is disposed on the impeller and is connected to the control valve signal.

[0019] Beneficial effect: In the present invention, the second sensor can determine whether the net is cleaned to the standard by detecting the resistance of the impeller rotation, and accordingly stop the operation of the cleaning device, thereby realizing automatic cleaning of the net without manual operation.

[0020] In an optional embodiment, the cleaning brush is cross-shaped.

[0021] Beneficial effect: When the cross-shaped cleaning brush of the present invention is cleaning a net, the water flow from the nozzle can rush toward the net from the gap between the impeller and the cleaning brush, thereby facilitating the flushing of attachments and dirt from the net.

[0022] In an optional embodiment, a reduction assembly is provided between the gear and the rack.

[0023] Beneficial effect: The present invention sets a reduction assembly between the gear and the rack, which can convert the high speed and low torque of the gear into low speed and high torque, so that the cleaning device can obtain sufficient driving force and maintain a relatively low speed to ensure the cleaning effect.

[0024] In a second aspect, the present invention further provides a method for cleaning a marine ranch aquaculture cage, which is applied to the above-mentioned marine ranch aquaculture cage cleaning device. The cleaning method comprises:

[0039] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0040] The following combination Figures 1 to 5 , describing embodiments of the present invention.

[0041] According to an embodiment of the present invention, on the one hand, Figures 1 to 4As shown, a marine ranch aquaculture cage cleaning device is provided, including a cage 1, a cleaning component 2 and an operating table. The cage 1 is suitable for being placed in water. The cage 1 includes a frame 101 and a net 102. Several frames 101 enclose a receiving cavity. The net 102 is installed on the frame 101. The cleaning component 2 is movably installed on the frame 101 and abuts against the net 102. The cleaning component 2 is located on the inner side of the cage 1. The operating table is set on the water surface, and the operating table is signal-connected to the cleaning component 2.

[0042] Specifically, in this embodiment, there is no specific limitation on the cage 1. For example, in this embodiment, the cage 1 is a cubic structure. The cage 1 includes a frame 101 and a net 102. The frame 101 is a cubic frame structure. The frame 101 can be made by welding stainless steel square tubes. Several columns are provided on each surface of the cubic frame 101, and an installation space is formed between two adjacent columns. The net 102 is installed in the installation space. Several nets 102 and the frame enclose a accommodating cavity suitable for breeding, and the cage 1 is suitable for being immersed in water.

[0043] In this embodiment, the cleaning component 2 is movably installed on two adjacent columns. The cleaning component 2 can move along the length direction of the columns. The cleaning component 2 is located inside the net box 1 and abuts against the net 102. During the movement, the cleaning component 2 cleans the net 102.

[0044] In this embodiment, the operating table is arranged above the water surface. The operating table is connected to the cleaning component 2 by signal. The operating table is suitable for controlling the start, stop and movement of the cleaning component 2.

[0045] The present invention movably installs the cleaning component 2 on the frame 101, and controls the cleaning component 2 to move along the inner side of the net 102 through the operating table to brush and clean the net 102, thereby removing debris and dirt attached to the net 102. There is no need to manually clean the net 102, and there is no need to remove the net box 1 from the water. The invention has good safety, convenient operation and high cleaning efficiency.

[0046] In one embodiment, the cleaning component 2 includes a mounting frame 201, an impeller 202, a water pipe 203, a cleaning brush 204 and a drive component. The mounting frame 201 is located on the inner side of the cage 1, and several impellers 202 are rotatably mounted on the mounting frame 201. The water pipe 203 is installed on the mounting frame 201. A nozzle 206 is provided at one end of the water pipe 203, and the nozzle 206 faces the impeller 202. The other end of the water pipe 203 is connected to the operating table. The cleaning brush 204 is arranged on the side of the impeller 202 away from the nozzle 206. The drive component is arranged on the mounting frame 201, the drive component is movably connected to the frame 101, and the drive component is connected to the operating table signal.

[0047] In this embodiment, the operating table is set above the water surface. The operating table includes a water inlet pipe, a high-pressure pump and a controller. One end of the water inlet pipe extends into the water, and the other end is connected to the high-pressure pump. The high-pressure pump is connected to the water pipe 203, and the high-pressure pump is connected to the controller signal. The other end of the water pipe 203 is provided with a nozzle 206, and a protective cover is provided outside the nozzle 206. In this embodiment, multiple nozzles 206 are provided at the end of the water pipe 203. The mounting frame 201 is movably mounted on the column, the nozzle 206 is fixed on the mounting frame 201, and multiple impellers 202 are rotatably mounted on the mounting frame 201. The number of impellers 202 is the same as the number of nozzles 206. The water outlet direction of each nozzle 206 is toward the impeller 202. The water flow sprayed by the nozzle 206 can drive the impeller 202 to rotate. A cleaning brush 204 is installed on the side of the impeller 202 away from the nozzle 206. The cleaning brush 204 is in contact with the surface of the net 102. When the impeller 202 rotates, the cleaning brush 204 also rotates to brush the surface of the net 102. The driving assembly is mounted on the mounting frame 201, and the driving assembly is movably connected to the column and the impeller 202. When the impeller 202 rotates, the driving assembly can drive the mounting frame 201 to move along the column, and the cleaning brush 204 can brush different positions on the net 102.

[0048] The present invention outputs water to the nozzle 206 through the water pipe 203. The water flow sprayed from the nozzle 206 drives the impeller 202 to rotate, driving the cleaning brush 204 to rotate on the surface of the net 102. As the impeller rotates, the driving component moves on the net box to clean the surface of the net 102. There is no need for manual cleaning of the net 102, and no electrical equipment is installed underwater, which reduces the failure rate of the device during use and ensures long-term operation of the device.

[0049] In one embodiment, the impellers 202 are arranged in two rows in parallel, and the impellers 202 in the two rows rotate in opposite directions.

[0050] Specifically, in this embodiment, two rows of impellers 202 are arranged in parallel on the mounting frame 201. The rotation directions of the blades on the two rows of impellers 202 are opposite. During operation, the water flow sprayed from the nozzle 206 drives one row of impellers 202 to rotate. When the mounting frame 201 moves to the extreme position along the column, the nozzle 206 is switched to discharge water, so that it drives the other row of impellers 202 to rotate in the opposite direction, causing the mounting frame 201 to move in the opposite direction, thereby allowing the cleaning brush 204 to brush the net 102 back and forth.

[0051] The present invention provides two types of impellers 202 with opposite rotation directions. By driving the impellers 202 with different rotation directions to rotate, the reciprocating movement of the cleaning component 2 can be achieved, which has the advantages of simple structure and convenient operation.

[0052] In one embodiment, the driving assembly includes a gear 2051 , which is coaxially connected to the impeller 202 . A rack 2052 is provided on the frame 101 , and the gear 2051 is meshed with the rack 2052 .

[0053] Specifically, in this embodiment, a gear 2051 is installed on the rotating shaft of the impeller 202, and racks 2052 are provided on both sides of the column of the frame 101. The gear 2051 and the rack 2052 are provided with matching teeth. The gear 2051 is engaged with the rack 2052 through the teeth. When the impeller 202 rotates, it drives the gear 2051 to rotate. By engaging the gear 2051 with the rack 2052, the gear 2051 moves along the extension direction of the rack 2052.

[0054] The present invention adopts a driving method of the gear 2051 and the rack 2052, which has a simple structure and good stability, and does not require the installation of electrical equipment. When the impeller 202 rotates, the gear 2051 can rotate accordingly.

[0055] In one embodiment, the water supply pipe 203 includes a main pipe 2031, a control valve 2032, a first branch pipe 2033 and a second branch pipe 2034. The control valve 2032 is arranged at the end of the main pipe 2031. The control valve 2032 is connected to the operating console signal. The first branch pipe 2033 is connected to the control valve 2032. The second branch pipe 2034 is connected to the control valve 2032. The first branch pipe 2033 and the second branch pipe 2034 are arranged in parallel.

[0056] Specifically, in this embodiment, two groups of impellers 202 are arranged side by side on the mounting frame 201. One end of the main pipe 2031 is connected to the high-pressure pump, and the other end is equipped with a control valve 2032. The control valve 2032 is connected to the controller signal. The control valve 2032 is respectively connected to a first branch pipe 2033 and a second branch pipe 2034. The first branch pipe 2033 and the second branch pipe 2034 are arranged in parallel, and the nozzles 206 are arranged on the first branch pipe 2033 and the second branch pipe 2034. The first branch pipe 2033 is corresponding to one row of impellers 202, and the second branch pipe 2034 is corresponding to the other row of impellers 202.

[0057] The present invention switches the connection between the main pipe 2031 and the first branch pipe 2033 and the second branch pipe 2034 through the control valve 2032, so as to drive the impellers 202 in different rows, thereby realizing the reciprocating movement of the driving assembly along the frame 101, with a simple structure and convenient operation.

[0058] In one embodiment, the cleaning assembly 2 further includes a first sensor, which is disposed at both ends of the rack 2052 and is connected to the control valve 2032 by signal.

[0059] Specifically, in this embodiment, a first sensor is installed at both ends of the rack 2052. The first sensor is a position sensor. When the gear 2051 moves to one end of the rack 2052, the first sensor is triggered, indicating that the cleaning component 2 has moved to the extreme position. At this time, the control valve 2032 switches the branch pipeline connected to it, so that the cleaning component 2 moves in the opposite direction, thereby realizing the reciprocating motion of the cleaning component 2.

[0060] The present invention is provided with a first sensor. When the gear 2051 moves to the end of the rack 2052, the first sensor outputs a signal, and the control valve 2032 switches the branch line connected to the main line 2031, thereby realizing the reversal of the cleaning component 2, which has the advantages of simple structure and convenient operation.

[0061] In one embodiment, the cleaning assembly 2 further includes a second sensor, which is disposed on the impeller 202 and is signal-connected to the control valve 2032 .

[0062] Specifically, in this embodiment, a second sensor is provided on the rotating shaft of the impeller 202, and the second sensor is a speed sensor. During the entire cleaning process, as the debris on the net 102 changes from more to less, the corresponding resistance of the debris to the rotation of the cleaning brush 204 also changes from large to small. Therefore, the rotation speed of the cleaning brush 204 changes from small to large, until the rotation speed of the cleaning brush 204 reaches a predetermined threshold, it is judged that the net 102 is cleaned to the standard, and the net 102 cleaning device can be stopped accordingly.

[0063] In the initial cleaning phase, if the rotation speed of the cleaning brush 204 remains at zero for a set period of time, it is determined that there is a mechanical fault or a pipeline fault in the cleaning device, and the controller may issue an alarm signal.

[0064] In the present invention, the second sensor can detect the resistance of the impeller 202 to determine whether the net 102 is cleaned to standard, and accordingly stop the cleaning device, thereby achieving automatic cleaning of the net 102 without manual operation.

[0065] In one embodiment, the cleaning brush 204 is cross-shaped.

[0066] Specifically, in this embodiment, the impeller 202 is provided with four blades, and the four blades are arranged in a cross shape. The cleaning brush 204 is also cross-shaped and is arranged corresponding to the blades. The cross-shaped brush body of the cleaning brush 204 is located below the blades, and the gaps between adjacent blades correspond to the brush body gaps of the cross brush. The water flow sprayed from the nozzle 206 can drive the impeller 202 and the cleaning brush 204 to rotate, and can also pass through the gaps between the blades and the gaps between the cleaning brush 204 to flush the net 102.

[0067] When the cross-shaped cleaning brush 204 of the present invention cleans the net 102 , the water flow from the nozzle 206 can rush toward the net 102 through the gap between the impeller 202 and the cleaning brush 204 , thereby facilitating the flushing of attachments and dirt from the net 102 .

[0068] In one embodiment, a reduction assembly is provided between the gear 2051 and the rack 2052 .

[0069] Specifically, in this embodiment, the gear 2051 and the rack 2052 are connected through a reduction assembly. In this embodiment, the transmission assembly is a reduction gear set. The gear 2051 on the impeller 202 is engaged with the small gear in the reduction gear set, the small gear is engaged with the large gear, and the large gear is engaged with the rack 2052.

[0070] The present invention sets a reduction assembly between the gear 2051 and the rack 2052, which can convert the high speed and low torque of the gear 2051 into low speed and high torque, so that the cleaning device can obtain sufficient driving force and maintain a low speed to ensure the cleaning effect.

[0071] According to an embodiment of the present invention, on the other hand, Figure 5 As shown, a method for cleaning a marine ranch cage is also provided, which is applied to the above-mentioned marine ranch cage cleaning device. The cleaning method includes:

[0072] Obtain the cleaning signal of the cage 1 and transmit the cleaning signal to the control valve 2032.

[0073] Specifically, after the cage 1 has been placed in water for a certain period of time, the controller obtains the time the cage 1 has been placed in water and generates a cleaning signal, which is then transmitted to the high-pressure pump and the control valve 2032 .

[0074] Water is input into the main pipe, and the control valve 2032 obtains a cleaning signal to connect the main pipe 2031 and the first branch pipe 2033.

[0075] Specifically, after the high-pressure pump and the control valve 2032 obtain the cleaning signal, the high-pressure pump inputs water into the main pipe body, the control valve 2032 connects the main pipe 2031 and the first branch pipe 2033, and the water is sprayed from the nozzle 206 on the first branch pipe 2033 to the impeller 202. The impeller 202 rotates under the action of the water flow, driving the cleaning brush 204 to brush the surface of the net 102. When the impeller 202 rotates, the gear 2051 rotates relative to the rack 2052, causing the mounting frame 201 to move along the column.

[0076] The reversing signal from the first sensor is obtained and transmitted to the control valve 2032 .

[0077] Specifically, when the mounting bracket 201 moves to the end of the rack 2052 , the first sensor detects that the mounting bracket 201 has moved to the extreme position of the column, and transmits a reversing signal to the control valve 2032 .

[0078] The control valve 2032 receives the reversing signal and connects the main pipe 2031 and the second branch pipe 2034 .

[0079] Specifically, the control valve 2032 connects the main line 2031 and the second branch pipe 2034. The nozzle of the second branch pipe 2034 outputs water flow to the second row of impellers 202 with opposite rotation directions, causing the impellers 202 with opposite rotation directions to rotate, driving the mounting frame 201 to move in the opposite direction, thereby achieving reciprocating scrubbing of the surface of the net 102.

[0080] Obtain the second sensor end signal and stop the cleaning operation.

[0081] Specifically, as the amount of debris on the net 102 decreases, the corresponding resistance of the debris to the rotation of the cleaning brush 204 also decreases. Therefore, the rotation speed of the cleaning brush 204 increases. When the second sensor detects that the rotation speed of the cleaning brush 204 reaches a predetermined threshold, it is determined that the net 102 cleaning meets the standards, and the net 102 cleaning device can be stopped accordingly.

[0082] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention. Such modifications and variations are all within the scope defined by the appended claims.
