Technical Field

[0001] The utility model relates to the technical field of cleaning and daily maintenance of aquaculture net cages, and in particular to a ship-borne aquaculture net cage cleaning device. Background Art

[0002] Cage farming is one of the main farming methods in aquaculture. The farming cages (cages) are easily attached by algae, shellfish and other organisms in the water. The undigested feed fed during the farming process and the excrement of the farmed animals will also provide nutrients for the attached organisms, thereby exacerbating the growth of the attached organisms; but the attached organisms not only compete for nutrients from the farmed organisms, but also clog the mesh of the farming cages, causing problems such as poor water quality exchange, reduced dissolved oxygen, and frequent fish diseases. In addition, the breeding of attached organisms will increase the load on the farming cages and affect the safety of the farming facilities.

[0003] At present, the main method for cleaning organisms attached to aquaculture cages is to bring the aquaculture cages back to the shore and clean them by high-pressure water impact or manual hammering, and the cleaning wastewater is directly discharged into the sea. This cleaning method is not only labor-intensive, labor-intensive, and polluting, but also reduces the service life of the aquaculture cages. Therefore, it is urgent to develop an in-situ cleaning equipment for aquaculture cages that can adapt to the characteristics of attached organisms in my country's aquaculture waters, so as to promote the mechanization and simplification of the cage aquaculture industry and promote the healthy development of the industry.

[0039] The present invention is further described in detail below in conjunction with the accompanying drawings and implementations. It is to be understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention are shown in the accompanying drawings.

[0040] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] In the field of cage aquaculture, generally, multiple parallel cables are stretched in shallow water areas, the aquatic products are placed in the aquaculture cages, and then multiple aquaculture cages containing aquatic products are evenly suspended on the cables.

[0042] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model provides a ship-mounted aquaculture net cage cleaning device, comprising a cage frame 1 matching the shape of the aquaculture net cage, the diameter of the cage frame 1 is slightly larger than the outer diameter of the aquaculture net cage, the length of the cage frame 1 is slightly larger than the length of the aquaculture net cage, and the cage frame 1 is a frame structure, and both ends of the cage frame 1 are open, so that the aquaculture net cage can enter from one end of the cage frame 1 and be sent out from the other end of the cage frame 1. In the utility model, when the aquaculture net cage is sent into the cage frame 1, the axial direction of the aquaculture mesh is consistent with the axial direction of the cage frame 1.

[0043] A longitudinal roller brush 3 is installed on the cage frame 1, and both ends of the longitudinal roller brush 3 are rotatably supported on the cage frame 1, and the longitudinal roller brush 3 is at least one group, and there is at least one longitudinal roller brush 3 in the same group. When the breeding net cage enters from one end of the cage frame 1 and is sent out from the other end of the cage frame 1, the longitudinal roller brush 3 fully rotates on the cage frame 1, thereby driving the breeding net cage to fully rotate in the cage frame 1 when passing through the cage frame 1. Since the longitudinal roller brush 3 will reduce the diameter of the space that can be passed through the cage frame 1 when arranged, and the structural strength of the breeding net cage itself is relatively small, the breeding net cage may shrink to a certain extent when subjected to radial extrusion. Therefore, in order to ensure that the longitudinal roller brush 3 can drive the breeding net cage to rotate synchronously through the friction between the longitudinal roller brush 3 and the breeding net cage when the longitudinal roller brush 3 is installed, after the longitudinal roller brush 3 is installed, the minimum diameter of the passing space formed by the rolling surfaces of multiple longitudinal roller brushes 3 needs to be slightly smaller than the outer diameter of the breeding net cage, or the minimum diameter of the passing space formed by the rolling surface of a longitudinal roller brush 3 and the inner wall of the cage frame 1 needs to be slightly smaller than the outer diameter of the breeding net cage. It should be noted that the passing space here refers to the cylindrical space that can be passed through by the breeding net cage.

[0044] The cage frame 1 is also equipped with a plurality of cleaning heads 4, which can be installed at different positions of the cage frame 1. When the breeding net cage enters and passes through the cage frame 1, the cleaning head 4 starts to clean the net cage. Since the breeding net cage rotates while moving backward, even if the position of the cleaning head 4 does not change, the cleaning head 4 can complete the cleaning of the entire breeding net cage.

[0045] When it is necessary to clean the aquaculture cage, the cage frame 1 is carried on the side of the operating vessel, and the operating vessel moves forward along the cable used to suspend the aquaculture cage. As the operating vessel moves forward, the relative position of the operating vessel and the aquaculture cage changes. When the front end of the cage frame 1 carried on the operating vessel is close to the aquaculture cage, since the position of the aquaculture cage itself does not change, the cage frame 1 will push the aquaculture cage to gradually tilt until it is horizontal as the operating vessel moves forward, so that the upper end of the aquaculture cage gradually enters the front end of the cage frame 1, and from the time the aquaculture cage enters the cage frame 1, the aquaculture cage is driven by the longitudinal roller brush 3 to rotate while moving backward in the cage frame 1, and the cleaning head 4 cleans the surface of the aquaculture cage during the rotation and backward movement of the aquaculture cage. Finally, as the operating vessel continues to move forward, the aquaculture cage is smoothly sent out from the rear end of the cage frame 1, and the cleaning head 4 completes the cleaning of the surface of the aquaculture cage.

[0046] The axial direction of the longitudinal roller brush 3 is consistent with the axial direction of the cage frame 1. When the breeding net cage enters the cage frame 1, the axial direction of the longitudinal roller brush 3 is consistent with the axial direction of the breeding net cage. Through the rotation of the longitudinal roller brush 3 and the friction between the longitudinal roller brush 3 and the breeding net cage, the longitudinal roller brush 3 drives the breeding net cage to rotate while rotating, so that the breeding net cage can rotate in the process of entering and passing through the cage frame 1.

[0047] When the longitudinal roller brush 3 is installed, the two ends of the longitudinal roller brush 3 are rotatably supported on the inner wall of the cage frame 1 through the bearing seat; at the same time, in the utility model, when the longitudinal roller brush 3 is a group, the length of the longitudinal roller brush 3 is adapted to the length of the cage frame 1, and when the longitudinal roller brush 3 is a plurality of groups, the total length of the plurality of groups of longitudinal roller brushes 3 is adapted to the length of the cage frame 1. Of course, in the utility model, the longitudinal roller brush 3 in the same group can be one or more, when the longitudinal roller brush 3 is a group, the longitudinal roller brush 3 in the same group is preferably multiple, and when the longitudinal roller brush 3 is a plurality of groups, the longitudinal roller brush 3 in the same group can be one or more; at the same time, when the longitudinal roller brush 3 is a group or / and there are a plurality of longitudinal roller brushes 3 in each group, the plurality of longitudinal roller brushes 3 in the same group are arranged at intervals along the circumferential direction of the cage frame 1, and when the longitudinal roller brush 3 is a plurality of groups and there is a single longitudinal roller brush 3 in each group, the longitudinal roller brushes 3 in two adjacent groups can be arranged in a staggered manner. Through the cooperation of multiple longitudinal roller brushes 3, during the whole process of the breeding net cage entering and passing through the cage frame 1 and being sent out, the breeding net cage can be driven to rotate by friction with the longitudinal roller brush 3, thereby ensuring that the cleaning head 4 cleans the breeding net cage.

[0048] like Figure 1 , Figure 3 As shown, at least one group of transverse roller brushes 2 is also installed on the cage frame 1. When the transverse roller brushes 2 are in one group, the group of transverse roller brushes 2 is located at the end where the breeding net cage first enters the cage frame 1. When the transverse roller brushes 2 are in two or more groups, it is necessary to ensure that two of the groups of transverse roller brushes 2 are located at the two ends of the cage frame 1. When the transverse roller brushes 2 are arranged, the axial direction of the transverse roller brushes 2 is consistent with the chord length direction of the cage frame 1, that is, when the transverse roller brushes 2 and the longitudinal roller brushes 3 are installed, the axial direction of the transverse roller brushes 2 is perpendicular to the axial direction of the longitudinal roller brushes 3; at the same time, there is at least one transverse roller brush 2 in each group. When there is one transverse roller brush 2 in each group, one transverse roller brush 2 in the group is located at the bottom of the cage frame 1, and when the breeding net cage enters and passes through the cage frame 1, one transverse roller brush 2 in each group supports the breeding net cage; when there are multiple transverse roller brushes 2 in each group, the multiple transverse roller brushes 2 in the group are arranged at intervals along the circumferential direction of the cage frame 1, and when the breeding net cage enters and passes through the cage frame 1, the multiple transverse roller brushes 2 in each group evenly press the breeding net cage in the circumferential direction.

[0049] In the utility model, after the transverse roller brush 2 is installed, no matter whether there is one or more transverse roller brushes 2 in each group, when the breeding net cage enters and passes through the cage frame 1, the rolling surface of the transverse roller brush 2 always maintains friction cooperation with the outer wall of the breeding net cage, that is, when the breeding net cage enters the cage frame 1, the friction cooperation between the outer wall of the breeding net cage and the rolling surface of the transverse roller brush 2 can drive the transverse roller brush 2 to rotate, so that the transverse roller brush 2 can guide the breeding net cage to enter the cage frame 1, reduce the friction between the breeding net cage and the cleaning frame, not only can the breeding net cage enter the cage frame 1 more smoothly, but also can pass through the cage frame 1 smoothly and be sent out of the cage frame 1, and the transverse roller brush 2 can also clean and scrape off a certain amount of shellfish, algae and other attachments on the breeding net cage while rotating.

[0050] Since the transverse roller brush 2 will cause the diameter of the passable space in the cage frame 1 to be reduced when it is arranged, and the structural strength of the breeding net cage itself is relatively small, the breeding net cage may shrink to a certain extent when subjected to radial compression. Therefore, in order to ensure that the breeding net cage can move more smoothly through the friction between the transverse roller brush 2 and the breeding net cage when entering and passing through the cage frame 1 after the transverse roller brush 2 is installed, after the transverse roller brush 2 is installed, the minimum diameter of the passable space formed by the rolling surfaces of multiple transverse roller brushes 2 in the same group needs to be slightly smaller than the outer diameter of the breeding net cage, or the minimum diameter of the passable space formed by the rolling surface of a transverse roller brush 2 in the same group and the inner wall of the cage frame 1 needs to be slightly smaller than the outer diameter of the breeding net cage.

[0051] It should be noted that the passing space here refers to the cylindrical space through which the breeding cages can pass; when there are multiple transverse roller brushes 2 in the same group, the multiple transverse roller brushes 2 in the same group together form a polygon. At this time, the passing space is the inscribed circle of the polygon. When there are multiple groups of transverse roller brushes 2, the inscribed circles of the polygons formed by the multiple transverse roller brushes 2 in each group are equal in size, and the centers of the inscribed circles of the polygons formed by the multiple transverse roller brushes 2 in each group are on the same straight line.

[0052] In order to make the driving of the longitudinal roller brush 3 more convenient, in the present invention, the transverse roller brush 2 and the longitudinal roller brush 3 can be connected by gear transmission. Since the breeding net cage will drive the transverse roller brush 2 to rotate in the process of entering and passing through the cage frame 1, and the transverse roller brush 2 and the longitudinal roller brush 3 are connected by gear transmission, the breeding net cage will drive the longitudinal roller brush 3 to rotate in the process of entering and passing through the cage frame 1, so that the rotation of the longitudinal roller brush 3 does not need to be driven by an additional power structure, making the structure of the present invention simpler.

[0053] In the present invention, since the central axis of the longitudinal roller brush 3 is arranged vertically with the central axis of the transverse roller brush 2, during actual installation, one end of the longitudinal roller brush 3 and one end of the transverse roller brush 2 need to be arranged close to each other, and bevel gears 7 are installed at one end of the longitudinal roller brush 3 and one end of the transverse roller brush 2 close to each other, and the transmission of the transverse roller brush 2 and the longitudinal roller brush 3 is realized by the meshing of the two bevel gears 7. In order to meet the rotation speed of the breeding net cage when entering the cage frame 1, the reduction ratio of the two meshing bevel gears 7 can be adjusted by replacing the corresponding gears, thereby changing the cleaning efficiency of the cleaning head 4 on the breeding net cage to ensure that the entire breeding net cage is cleaned.

[0054] In the utility model, each longitudinal roller brush 3 can be connected to one of the transverse roller brushes 2 in a group through one end thereof, or the two ends of each longitudinal roller brush 3 can be connected to one of the transverse roller brushes 2 in two groups respectively; at the same time, in order to meet the driving requirements of the longitudinal roller brush 3, in a group of longitudinal roller brushes 3 and a group of transverse roller brushes 2 located at adjacent positions, the number of longitudinal roller brushes 3 in the group is not greater than the number of transverse roller brushes 2 in the group.

[0055] Specifically, in the utility model, there are 2 groups of longitudinal roller brushes 3 and 3 groups of transverse roller brushes 2. The number of longitudinal roller brushes 3 in each group is 1. The longitudinal roller brushes 3 in the two groups are staggered, and the 3 groups of transverse roller brushes 2 are respectively located at the two ends and the middle of the cage frame 1. The number of transverse roller brushes 2 in a group located at both ends of the cage frame 1 is 3, and the number of transverse roller brushes 2 in a group located in the middle of the cage frame 1 is 2. A transverse roller brush 2 located at the front end of the cage frame 1 is gear-engaged with a longitudinal roller brush 3 near the front end of the cage frame 1, and a transverse roller brush 2 located at the rear end of the cage frame 1 is gear-engaged with a longitudinal roller brush 3 near the rear end of the cage frame 1.

[0056] In the present invention, a plurality of the cleaning heads 4 are arranged at intervals along the length direction of the cage frame 1, and the axial distance between two adjacent cleaning heads 4 may be equal or unequal, and the specific axial distance between two adjacent cleaning heads 4 may be adjusted according to actual conditions. Since the breeding net cage rotates while passing through the cage frame 1, and the position of the cleaning head 4 on the cage frame 1 is fixed, when the breeding net cage passes through the cage frame 1, the path of the cleaning head 4 on the breeding net cage is actually a spiral cleaning path; in the present invention, the plurality of cleaning heads 4 installed on the cage frame 1 cooperate with each other, so that when the breeding net cage passes through the cage frame 1, the plurality of cleaning heads 4 can have multiple cleaning paths on the breeding net cage at the same time, and the plurality of cleaning paths cooperate with each other, so that the cleaning effect of the breeding net cage is better.

[0057] like Figure 1 , Figure 2As shown, in the present invention, when multiple cleaning heads 4 are arranged, multiple cleaning heads 4 can also be arranged in a staggered manner, so that when the breeding net cage passes through the cage frame 1, the multiple cleaning heads 4 and the breeding net cage initially contact different points, thereby ensuring that the cleaning paths of the multiple cleaning heads 4 on the breeding net cage will not overlap, so that the multiple cleaning heads 4 can jointly clean the breeding net cage, ensuring that the cleaning of the breeding net cage is more thorough. When there are multiple cleaning heads 4 in the present invention, the multiple cleaning heads 4 are evenly spaced in the circumferential direction of the cage frame 1, so that the angles of two adjacent cleaning heads 4 in the circumferential direction of the cage frame 1 are equal. For example, when there are three cleaning heads 4, the three cleaning heads 4 are respectively located at 120°, 240°, and 360° in the circumferential direction of the cage frame 1; of course, when there are multiple cleaning heads 4 in the present invention, the angles of two adjacent cleaning heads 4 in the circumferential direction of the cage frame 1 may not be equal. Under the condition of meeting the requirements for cleaning the breeding net cage, the angles of two adjacent cleaning heads 4 in the circumferential direction of the cage frame 1 can be arranged at will.

[0058] like Figure 4 , Figure 5 , Figure 6 As shown, the cleaning head 4 includes a cleaning disc 401, which is located on the inner side of the cage frame 1, and the diameter direction of the cleaning disc 401 is consistent with the axial direction of the cage frame 1, and the cleaning disc 401 can fully rotate relative to the cage frame 1; a plurality of blades 403 and a plurality of high-pressure nozzles 402 are also installed on the cleaning disc 401, and the plurality of high-pressure nozzles 402 and the plurality of blades 403 are evenly spaced and arranged along the circumferential direction of the cleaning disc 401, wherein, when the high-pressure water flow passes through the high-pressure nozzle 402, the high-pressure water flow forms a cavitation jet inside the high-pressure nozzle 402, and the crushing force formed by the rupture of a large number of cavitation bubbles in the cavitation jet cleans the attachments on the breeding net cage, and the blades 403 crush and scrape the attached organisms on the breeding net cage through the cleaning disc 401.

[0059] In order to prevent the high-pressure nozzle 402 from directly hooking on the breeding net cage without the blade 403 crushing or scraping the organisms attached to the breeding net cage during the rotation of the cleaning disc 401, the height of the high-pressure nozzle 402 on the cleaning disc 401 is lower than the height of the blade 403 on the cleaning sheet, so that the high-pressure nozzle 402 will not contact the breeding net cage during the rotation of the cleaning disc 401, thereby preventing the breeding net cage from being damaged by the high-pressure nozzle 402; at the same time, in order to prevent the blade 403 from being hooked on the breeding net cage during the rotation of the cleaning disc 401, the cutting edge of the blade 403 can be set to an inclined shape, and the height of the cutting edge of the blade 403 on the cleaning disc 401 is gradually reduced based on the rotation direction of the cleaning disc 401, so that the cutting edge of the blade 403 will crush and scrape the organisms attached to the breeding net cage during the rotation of the cleaning disc 401 without damaging the breeding net cage. In order to make the edge of the blade 403 smoother, the edge of the blade 403 and the two sides of the blade 403 are transitioned through an arc, so as to avoid the blade 403 from hooking the breeding net cage as much as possible.

[0060] In order to drive the cleaning disc 401, multiple high-pressure nozzles 402 can be evenly spaced along the circumferential direction of the cleaning disc 401, and when the high-pressure nozzles 402 are installed, the outlet ends of the multiple high-pressure nozzles 402 are all inclined in the same circumferential direction of the cleaning disc 401. It should be noted that the inclination of the high-pressure nozzles 402 is not radially inclined in the cleaning disc 401, but is inclined in the tangential direction of the ring formed by the multiple high-pressure nozzles 402. Since the plurality of high-pressure nozzles 402 are fixed on the cleaning disk 401, and the high-pressure water flow exerts a reverse force on the high-pressure nozzle 402 while being sprayed, the reverse force on the high-pressure nozzle 402 is inclined along the tangent direction of the ring formed by the plurality of high-pressure nozzles 402. Therefore, through the cooperation of the plurality of high-pressure nozzles 402, when the plurality of high-pressure nozzles 402 spray out high-pressure water flow at the same time, the reverse forces on the plurality of high-pressure nozzles 402 act together on the cleaning disk 401, so that the cleaning disk 401 is fully rotated on the cage frame 1, so that the cleaning disk 401 does not need to be driven by an additional power structure, making the driving of the cleaning disk 401 simpler; at the same time, through the rotation of the cleaning disk 401, the blade 403 on the cleaning disk 401 rotates synchronously, thereby ensuring that the blade 403 crushes and scrapes the organisms attached to the breeding net cage.

[0061] In the present invention, in order to prevent the blade 403 from hooking the breeding net cage during the process of crushing and scraping the organisms attached to the breeding net cage, the cutting edge of the blade 403 is set to be inclined. Therefore, in order to ensure that the cleaning disc 401 cooperates with the inclined direction of the cutting edge of the blade 403 when rotating, the high-pressure nozzle 402 must ensure that the inclined direction of the high-pressure nozzle 402 is consistent with the inclined direction of the cutting edge of the blade 403 when installing. Specifically, the lower end of the high-pressure nozzle 402 is located on the same side as the lower end of the cutting edge of the blade 403, and the high end of the high-pressure nozzle 402 is located on the same side as the high end of the cutting edge of the blade 403. The ends are located on the same side, where the lower end of the blade 403 edge is the end at which the blade 403 edge is at a higher height on the cleaning disc 401, and the higher end of the blade 403 edge is the end at which the blade 403 edge is at a lower height on the cleaning disc 401, so that when the high-pressure water ejected by the plurality of high-pressure nozzles 402 drives the cleaning disc 401 to rotate by reaction, based on the rotation direction of the cleaning disc 401, the height of the blade 403 edge on the cleaning disc 401 gradually decreases, thereby preventing the blade 403 edge from hooking and breaking the breeding net cage when crushing and scraping the attached organisms on the breeding net cage.

[0062] The angle between the high-pressure nozzle 402 and the cleaning disk 401 is 30°, and the specific angle between the high-pressure nozzle 402 and the cleaning disk 401 can be adjusted according to actual conditions.

[0063] Since the surface of the breeding net cage is not flat, in order to ensure that the cleaning head 4 is always in close contact with the surface of the cage frame 1 when the cleaning net cage passes through the cage frame 1, an elastic seat must be installed on the cage frame 1 when the cleaning head 4 is installed. The elastic force direction of the elastic seat is consistent with the radial direction of the cage frame 1; at the same time, a rotating joint 11 is also installed on the elastic seat. The rotating joint 11 itself is a direct use of the existing technology. The outer wall of the rotating joint 11 has a water inlet for pipe connection. The inner tube of the rotating joint 11 serves as a water outlet. The inner tube extension end of the rotating joint 11 is connected to a structure that performs rotating motion.

[0064] Since the high-pressure nozzle 402 in the utility model is fixed on the cleaning disc 401, both the high-pressure nozzle 402 and the rotating disc need to rotate. Therefore, the rotating disc is directly fixed on the inner tube extension end of the rotating joint 11 during installation, and the inner tube extension end of the rotating joint 11 is connected to the plurality of high-pressure nozzles 402 through pipelines, which not only ensures that the high-pressure water flow is delivered to each high-pressure nozzle 402, but also enables the cleaning disc 401 to fully rotate relative to the cage frame 1.

[0065] When the breeding net cage passes through the cage frame 1, the elastic seat can move toward the outer wall of the breeding net cage through its own elastic rotating joint 11 and the cleaning head 4 installed on the inner tube of the rotating joint 11, so that the cleaning head 4 is always pressed against the surface of the breeding net cage, achieving close cleaning of the breeding net cage and ensuring the cleaning effect of the breeding net cage.

[0066] The cleaning disc 401 is in the shape of a cap. At this time, the high-pressure nozzle 402 is fixed on the inner top of the cleaning disc 401, and the blade 403 is fixedly installed on the edge of the cleaning disc 401 by screws; at the same time, in order to reduce the weight of the cleaning disc 401, the top surface of the cleaning disc 401 can also be eliminated, and then staggered connecting rods can be installed in the cleaning disc 401. At this time, the high-pressure nozzle 402 can be fixed on the connecting rod, and the staggered center of the multiple connecting rods can be fixed on the inner tube extension end of the rotary joint 11.

[0067] like Figure 4 , Figure 5 As shown, the elastic seat includes a fixed shaft 8 fixed on the rotating joint 11, and the central axis of the fixed shaft 8 is in the same straight line with the central axis of the rotating joint 11. Since the outer shell of the rotating joint 11 does not rotate, the fixed shaft 8 does not rotate after being installed on the rotating joint 11; the cage frame 1 also has a mounting hole that is clearance-matched with the fixed shaft 8, and one end of the fixed shaft 8 away from the rotating joint 11 extends outward through the mounting hole, and the extended end of the fixed shaft 8 has a limiting plate 9, and the diameter of the limiting plate 9 is larger than the diameter of the mounting hole on the cage frame 1 to prevent the fixed shaft 8 from falling off directly from the cage frame 1; the fixed shaft 8 is also sleeved with a compression spring 10, one end of the compression spring 10 is pressed against the inner wall of the cage frame 1, and the other end of the compression spring 10 is pressed against the rotating joint 11.

[0068] When the breeding net cage passes through the cage frame 1, when the surface of the breeding net cage is in an outward convex state corresponding to the cleaning head 4, the breeding net cage will apply a thrust to the cage frame 1 on the cleaning head 4. After receiving the thrust to the cage frame 1, the cleaning head 4 transmits the thrust to the rotating joint 11. After being subjected to the force, the rotating joint 11 compresses the compression spring 10. During the compression of the compression spring 10, the fixed shaft 8 moves toward the outside of the cage frame 1 to ensure that the breeding net cage passes through the cage frame 1 smoothly; when the surface of the breeding net cage is in an inward concave state corresponding to the cleaning head 4, there is a certain gap between the breeding net cage and the cleaning head 4. At this time, the compression spring 10 pushes the rotating joint 11 to move toward the outer wall of the breeding net cage through its own elastic force. While moving, the rotating joint 11 drives the fixed shaft 8 and the cleaning head 4 to move synchronously toward the outer wall of the breeding net cage, so that the cleaning head 4 is pressed against the outer wall of the breeding net cage to ensure that the cleaning head 4 cleans the breeding net cage.

[0069] like Figure 7 , Figure 8As shown, the utility model further includes a high-pressure water pump 12. Since the utility model needs to be carried on an operating vessel when in use, the high-pressure water pump 12 can be directly installed on the operating vessel. When in use, the high-pressure water pump 12 can directly draw water from the sea, and the outlet end of the high-pressure water pump 12 can be respectively connected to the rotary joints 11 on the multiple cleaning discs 401, so that the seawater drawn by the high-pressure water pump 12 can be directly used by the high-pressure nozzles 402 on the multiple cleaning discs 401, which is convenient for water collection, so that the water used for cleaning the breeding cages is the same as the water required for the aquatic products in the breeding cages, not only the water used for cleaning the breeding cages will not cause discomfort to the aquatic products in the breeding cages, but also the water after cleaning the breeding cages can be directly discharged into the sea without causing environmental pollution.

[0070] In order to allow the breeding net cage to smoothly enter the cage frame 1, a guide plate 6 can also be installed at the inlet end of the cage frame 1; at the same time, since the breeding net cage is suspended on the cable during the aquaculture process, and the breeding net cage first contacts the bottom of the cage frame 1 during the process of gradually tilting into the cage frame 1, the guide plate 6 can be directly installed at the bottom of the inlet end of the cage frame 1 when installing, and the end of the guide plate 6 away from the cage frame 1 is tilted toward the outside of the cage frame 1.

[0071] By installing the guide plate 6, the breeding net cage can be supported on the guide plate 6 when it gradually enters the cage frame 1. As the operating vessel moves forward, the breeding net cage can gradually enter the cage frame 1 under the guidance of the guide plate 6, effectively reducing the friction between the breeding net cage and the inlet end of the cage frame 1, making it smoother for the breeding net cage to enter the cage frame 1.

[0072] In order to prevent the extended end of the guide plate 6 from hooking the breeding net cage when the breeding net cage enters the guide plate 6, the extended end of the guide plate 6 can be further folded outward so that the breeding net cage directly contacts the arc portion of the folded extended end of the guide plate 6 when contacting the guide plate 6, thereby effectively preventing the breeding net cage from being damaged.

[0073] The inclination angle of the guide plate 6 installed on the cage frame 1 can be adjusted according to the state of the breeding net cage entering the cage frame 1, and in order to facilitate the adjustment of the inclination angle of the guide plate 6, a sleeve can be installed on the cage frame 1, and a pin can be installed on the guide plate 6, and the pin is inserted in the sleeve so that the guide plate 6 can be rotated on the cage frame 1. In order to lock the guide plate 6 with the cage frame 1 after it is rotated to a fixed angle, threads can be provided at both ends of the pin, and nuts can be sleeved at both ends of the pin, and the pin and the sleeve can be locked and fixed by tightening the nuts, thereby fixing the guide plate 6 to the cage frame 1.

[0074] like Figure 1 , Figure 2 , Figure 3As shown, the cage frame 1 includes an upper frame 101 and a lower frame 102, the upper frame 101 and the lower frame 102 are semicircular, and the upper frame 101 and the lower frame 102 are detachably connected, so that the utility model can install the entire cage frame 1 on the working vessel or only install the lower frame 102 on the working vessel according to actual needs. For example: when the breeding net cage needs to be cleaned, the entire cage frame 1 needs to be installed on the working vessel, at this time, the upper frame 101 and the lower frame 102 can be fixed; when only the breeding net cage needs to be fed, seedlings are separated, and the breeding conditions inside the net cage are observed, the upper frame 101 in the cage frame 1 can be removed, and only the lower frame 102 can be installed on the working vessel, at this time, the breeding net cage does not need to be cleaned.

[0075] Since the lower frame 102 is mainly used for feeding, separating seedlings and observing the conditions of the cultured objects inside the breeding cage when used alone, the cleaning head 4 in the utility model can be installed only on the upper frame 101 during installation; at the same time, during the process of feeding, separating seedlings and observing the conditions of the cultured objects inside the breeding cage, the breeding cage still needs to be rotated, so the longitudinal roller brush 3 and the transverse roller brush 2 are preferentially installed on the lower frame 102, which can effectively ensure that the breeding cage can smoothly enter the lower frame 102.

[0076] In the present invention, in order to facilitate the installation and disassembly of the upper frame 101 and the lower frame 102, multiple sleeves 103 are installed on the matching edges of the upper frame 101 and the lower frame 102. When the upper frame 101 and the lower frame 102 are closed, the multiple sleeves 103 on the matching edge of the upper frame 101 and the multiple sleeves 103 on the matching edge of the lower frame 102 are in the same straight line. At this time, a shaft rod 104 is inserted into the multiple sleeves 103 on the matching edge of the upper frame 101 and the multiple sleeves 103 on the matching edge of the lower frame 102 to complete the installation of the upper frame 101 and the lower frame 102; when the upper frame 101 needs to be removed, the shaft rod 104 is directly pulled out and the upper frame 101 is removed. Of course, the upper frame 101 and the lower frame 102 in the present invention can also be conveniently installed and disassembled in other ways, for example, the upper frame 101 and the lower frame 102 are installed by locking.

[0077] In order to facilitate the use of the utility model on the side of the working vessel, a hanging structure that can be hung on the side of the vessel needs to be installed on the cage frame 1; at the same time, since the lower frame 102 can also be used alone, the hanging structure is preferably laid on the lower frame 102 when laid out. The hanging structure is a hook.

[0078] Since the utility model is often in contact with water during use, in order to improve the corrosion resistance of the utility model, the utility model is made of corrosion-resistant materials, such as 304 stainless steel, titanium alloy, etc.

[0079] The specific working process of the utility model is as follows:

[0080] like Figure 7 , Figure 8 As shown, the cage frame 1 is suspended on the side of the working vessel through the suspension device 5, the high-pressure water pump 12 is installed on the working vessel, and the water inlet pipe of the high-pressure water pump 12 with a filter is extended into the seawater, and the water outlet of the high-pressure water pump 12 is connected to the water inlet of the rotary joint 11 in each cleaning head 4 by a pipeline.

[0081] The working vessel is moved along the direction of the cable used to hang the breeding net cage. The working vessel drives the cage frame 1 to move forward synchronously, so that the breeding net cage suspended on the cable moves backward relative to the cage frame 1. As the working vessel gradually moves forward, when the front end of the cage frame 1 carried on the working vessel approaches the breeding net cage, since the position of the breeding net cage itself does not change, the cage frame 1 will push the breeding net cage to gradually tilt until it is horizontal as the working vessel moves forward. In this process, the breeding net cage gradually enters the front end of the cage frame 1 under the guidance of the guide plate 6. As the working vessel continues to move forward, the breeding net cage will gradually tilt and enter the front end of the cage frame 1. When the aquaculture net cage moves forward, it enters the inlet end of the cage frame 1. When the aquaculture net cage contacts the transverse roller brush 2 at the inlet end of the cage frame 1, the transverse roller brush 2 and the aquaculture net cage are frictionally matched, and the aquaculture net cage pushes the transverse roller brush 2 to rotate. While the transverse roller brush 2 rotates, it drives the longitudinal roller brush 3 to rotate through gear meshing. When the longitudinal roller brush 3 rotates, it frictionally matches with the aquaculture net cage, so that not only the aquaculture net cage rotates in the process of entering the cage frame 1, but also the longitudinal roller brush 3 and the transverse roller brush 2 can preliminarily clean and scrape off a certain amount of shellfish, algae and other attachments on the aquaculture net cage.

[0082] As the breeding net cage gradually moves toward the outlet end of the cage frame 1, the high-pressure water pump 12 is started, and the high-pressure water pump 12 delivers high-pressure water to the rotary joint 11. The high-pressure water entering the rotary joint 11 is finally sprayed out by multiple high-pressure nozzles 402 on the cleaning disk 401. The multiple high-pressure nozzles 402 drive the cleaning disk 401 to rotate while spraying high-pressure water, and the cleaning disk 401 rotates while driving the blade 403 to rotate synchronously; at the same time, when the breeding net cage contacts the cleaning head 4, the blade 403 driven by the cleaning disk 401 is crushed and scraped off the attached organisms on the breeding net cage, and the high-pressure water sprayed by the high-pressure nozzle 402 is used to rinse the attached organisms remaining on the breeding net cage, thereby completing the cleaning of the breeding net cage.

[0083] As the breeding net cage continues to move toward the exit end of the cage frame 1, the breeding net cage rotates through the cage frame 1. During this process, multiple cleaning heads 4 cooperate to finally complete the cleaning of the breeding net cage, and the cleaned breeding net cage is finally sent out from the exit end of the cage frame 1, thereby completing a breeding net cage cleaning operation process.

[0084] Repeat the above steps, and the operating vessel continues to move forward to complete the cleaning of the next aquaculture cage.

[0085] When daily maintenance work is required on the breeding cage, the details are as follows:

[0086] like Fig. 9 As shown, the staff removes the upper frame 101 from the lower frame 102, and hangs the lower frame 102 on the side of the working vessel through the hanging device 5, and moves the working vessel along the direction of the cable used to hang the breeding net cage. The forward movement of the working vessel drives the cage frame 1 to move forward synchronously, so that the breeding net cage hung on the cable moves backward relative to the cage frame 1; as the working vessel gradually moves forward, when the front end of the cage frame 1 carried on the working vessel approaches the breeding net cage, since the position of the breeding net cage itself does not change, the cage frame 1 will push the breeding net cage to gradually tilt until it is horizontal when moving forward with the working vessel. In this process, the breeding net cage is guided by the material guide. The plate 6 gradually guides the aquaculture cage to enter the front end of the cage frame 1; as the operating vessel continues to move forward, the aquaculture cage enters the inlet end of the lower frame 102, and when the aquaculture cage contacts the transverse roller brush 2 at the inlet end of the lower frame 102, the transverse roller brush 2 and the aquaculture cage are frictionally matched, and the aquaculture cage pushes the transverse roller brush 2 to rotate, and the transverse roller brush 2 drives the longitudinal roller brush 3 to rotate through gear meshing while rotating, and the longitudinal roller brush 3 rotates through friction with the aquaculture cage when rotating, so that not only the aquaculture cage rotates in the process of entering the cage frame 1, but also the longitudinal roller brush 3 and the transverse roller brush 2 can preliminarily clean and scrape off a certain amount of shellfish, algae and other attachments on the aquaculture cage.

[0087] When the breeding cage rotates on the lower frame 102 and moves toward the outlet end of the lower frame 102, the staff can not only observe the rotation of the horizontal roller brush 2 and the longitudinal roller brush 3, but also feed and separate the aquatic products in the breeding cage and observe the growth of the aquatic products inside the breeding cage, thereby completing the maintenance of a breeding cage.

[0088] Repeat the above steps, and the operating vessel continues to move forward to complete the maintenance of the next aquaculture cage.

[0089] After the routine maintenance of the breeding cage is completed, the upper frame 101 and the lower frame 102 are assembled and fixed together.
