[0065] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0066] Example 1:

[0067] like Figure 1-Figure 4 As shown, the fishery cage capable of preventing the growth of marine organisms in this embodiment includes a frame structure 1, a pair of rails 2, a fishing net 3 corresponding to the frame structure 1, a pair of sliding chains 4, a driving device 5 and a cleaning device.

[0068] A frame structure 1, the side walls of the frame structure 1 form multiple fishing net installation frames 11; a pair of tracks 2, arranged on the frame structure 1 on both sides of the fishing net installation frame 11; a fishing net member 3, which is a flat annular cylinder with both ends connected, and the axis of the fishing net member 3 is consistent with the horizontal direction; a pair of sliding chains 4, corresponding to the two ends of the fishing net member 3 respectively, a single sliding chain 4 is annular, one side of the sliding chain 4 is connected to one end of the fishing net member 3, and the other side of the sliding chain 4 is slidingly connected to the track 2, and the fishing net member 3 covers the fishing net installation frame 11 to form the water-passing side wall of the net box; a driving device 5, installed on the frame structure 1, and the driving device 5 is connected to the sliding chain 4 for driving the sliding chain 4 to move along the predetermined track of the track 2; a cleaning device, provided on the fishing net installation frame 11, and corresponding to the fishing net member 3.

[0069] When the sliding chain 4 moves, it drives the fishing net 3 to roll from both ends of the fishing net 3, so that the fishing net 3 interacts with the cleaning device to remove organisms on the fishing net 3.

[0070] Further, if Figure 1 As shown, the frame structure 1 has a horizontal cross-section that is a regular polygon, and the number of the fishing net installation frames 11 is equal to the number of sides of the regular polygon.

[0071] Specifically, such as Figure 1 As shown, the frame structure 1 includes an upper polygonal frame and a lower polygonal frame. The upper polygonal frame has the same and corresponding number of sides as the lower polygonal frame. The upper polygonal frame and the lower polygonal frame are connected by a plurality of columns 12. Adjacent columns 12 and the partial structures of the upper polygonal frame and the lower polygonal frame are combined to form a fishing net installation frame 11. The installation positions of the columns 12 correspond to the vertices of the polygon, which is the case with the least number of columns 12.

[0072] The frame structure 1 needs to be arranged with a fishing net to form a net cage, especially the side walls and the bottom need to be covered with a fishing net to prevent the fish in the net cage from leaving the net cage. After the fishing net member 3 in this embodiment is installed on the fishing net mounting frame 11, a side wall for water to enter and exit the net cage is formed, that is, a water-passing side wall.

[0073] like Figure 1 As shown, the fishing net 3 is formed by connecting a rectangular fishing net end to end, forming a double-layer net. The track 2 is set on the column 12 along the length direction of the column 12. The predetermined track of the track 2 is closed. The driving device 5 drives the sliding chain 4 to move along the predetermined track of the track 2. The sliding chain 4 then drives the cylindrical fishing net 3 to roll around its own axis without changing its overall shape, thereby changing the working position of the fishing net 3 in the cleaning device.

[0074] The cleaning device is preferably installed on the upper part of the frame structure 1 and is located above the water plane when in operation, so that the cleaning device can act on the fishing net 3 outside the water body. The action position of the fishing net 3 and the cleaning device is preferably located above the water plane.

[0075] The fishery cage is equipped with a control system, which controls the start and stop of the driving device 5 and the rolling speed of the fishing net 3 according to instructions. The control system also controls the start and stop and operation frequency of the cleaning device to realize remote cleaning operations of the fishery cage and achieve unmanned operation.

[0076] By arranging tracks 2 and driving devices 5 on both sides of the fishing net installation frame 11 of the cage frame structure 1, and installing a rollable double-layer mesh fishing net member 3 at the fishing net installation frame 11, the fishing net member 3 moves along a predetermined track of the track 2 under the drive of the driving device 5, and changes the working position of the cleaning device. The fishing net is automatically cleaned while the breeding work is in progress, which does not affect the breeding cycle and has good economic efficiency, can prevent the wild growth of marine organisms, and is harmless to the farmed fish.

[0077] The fishery cages of this embodiment, which can prevent the growth of marine organisms, can effectively prevent and remove the attachment of large and small marine organisms, maintain the water flow transmittance of the net, do not affect the aquaculture cycle, and are harmless to the farmed fish. This improves the economic and practicality of marine aquaculture equipment and promotes the development of the aquaculture industry. The removed organisms include larger marine organisms and microorganisms.

[0078] Further, if Figure 1-Figure 3 As shown, the cleaning device includes a physical cleaning system 6, which includes: a guide rail 61, installed on the upper part of the fishing net mounting frame 11, and the guide rail 61 is arranged in a horizontal direction; a high-pressure water gun 62, slidably installed on the guide rail 61, and the high-pressure water gun 62 corresponds to the fishing net part 3; a transverse drive, installed on the fishing net mounting frame 11 on one side of the guide rail 61, for driving the high-pressure water gun 62 to move along the guide rail 61.

[0079] Specifically, the physical cleaning system 6 is installed on the upper polygonal frame of the frame structure 1; the high-pressure water gun 62 moves along the guide rail 61 and sprays high-pressure water to remove larger marine organisms attached to the fishing net 3; the transverse drive is a traditional drive structure, such as a gear rack structure driven by a motor, and the high-pressure water gun 62 moves synchronously with the driving gear of the motor; when the physical cleaning system 6 is working, the physical cleaning system 6 is located above the waterline.

[0080] Further, if Figure 11-13 As shown, the cleaning device includes a chemical cleaning system 7, which includes: a chemical tank 71, installed on the upper part of the fishing net mounting frame 11, the chemical tank 71 is a trough-shaped structure with an open upper part, and the length direction of the chemical tank 71 is consistent with the horizontal direction. The chemical tank 71 is used to contain a chemical solution, and the chemical solution is used to react with the fishing net part 3.

[0081] Specifically, the medicine tank 71 is installed between a pair of rails 2, and the upper end of the rail 2 extends into the medicine tank 71. Figure 2 and Figure 11 As shown, the upper end portion of the track 2 is immersed in the chemical solution in the chemical tank 71. Under the guidance of the track 2, the single-layer net of the fishing net 3 passes through the chemical tank 71 in sequence, and is soaked in the chemical solution to remove microorganisms attached to the net. The chemical solution can be a hypochlorous acid solution. When working, the hypochlorous acid concentration can be controlled in the range of 40 to 80 ppm. When the chemical cleaning system 7 is working, the chemical cleaning system 7 is located above the waterline.

[0082] The rolling system consisting of the drive device 5, the sliding chain 4 and the track 2 drives the fishing net 3 to roll, so that the net of the fishing net 3 is first cleaned by the physical cleaning system 6 to remove larger marine organisms on the fishing net, and then the chemical cleaning system 7 is used to remove microorganisms on the fishing net, thereby achieving the purpose of preventing the growth of marine organisms.

[0083] Further, if Figure 12-13 As shown, an electrolytic box 72 is provided in the reagent tank 71. The structure of the electrolytic box 72 includes: a box body 721, which is provided in the reagent tank 71, and a water inlet 722 is provided at one end of the box body 721, and a water outlet 723 is provided at the other end of the box body 721; a positive electrode 724 and a negative electrode 725, which are installed on the inner wall of the box body 721 between the water inlet 722 and the water outlet 723, and are arranged opposite to each other; a water pump 726, which is installed on the box body 721 on one side of the water inlet 722, and is used to pump seawater in the reagent tank 71 into the box body 721. After that, hypochlorous acid is generated under the action of the positive electrode 724 and the negative electrode 725, and the seawater containing hypochlorous acid enters the reagent tank 71 through the water outlet 723.

[0084] Specifically, seawater is used as a raw material for electrolysis in the reagent tank 71 to generate sodium hypochlorite, which is hydrolyzed to form a hypochlorous acid solution. The seawater in the reagent tank 71 needs to be added or replaced before the chemical cleaning system 7 is used or regularly. A water pump can be installed on the column 12 to pump seawater into the reagent tank 71 or to pump seawater out of the reagent tank 71. The addition and replacement of seawater can also be automatically controlled by means of liquid level detection, pipeline switching, etc. The box 721 is located below the liquid level in the reagent tank 71 and is fixedly installed on the side wall of the box 721. The number and current intensity of the electrolytic boxes 72 can be determined according to the decontamination intensity requirements to control the hypochlorous acid concentration. In order to facilitate the control of the hypochlorous acid concentration, a hypochlorous acid concentration detection sensor is provided in the reagent tank 71 to output a concentration signal to the control system to control the opening and closing of the electrolytic boxes 72 and the current intensity.

[0085] By arranging an electrolytic box 72 in the reagent tank 71, a reagent solution containing hypochlorous acid can be prepared independently using seawater as raw material, so that the concentration of the reagent solution in the reagent tank 71 can be controlled online, and remote operation when using the chemical cleaning system 7 to remove microorganisms on the fishing net can be achieved, thereby reducing the maintenance cost of the cage and improving work efficiency.

[0086] Further, if Figure 2-Figure 3 As shown, the track 2 is installed on the columns 12 on both sides of the fishing net installation frame 11. The length direction of the track 2 is consistent with the vertical direction. The structure of the track 2 includes:

[0087] The first straight groove 21 and the second straight groove 22 are installed in parallel and spaced apart on the side wall of the column 12, and the length direction of the first straight groove 21 and the second straight groove 22 is consistent with the length direction of the column 12; it also includes an upper turning portion 23 and a lower turning portion 24 with a groove-shaped structure, the upper turning portion 23 is connected to the upper ends of the first straight groove 21 and the second straight groove 22, and the lower turning portion 24 is connected to the lower ends of the first straight groove 21 and the second straight groove 22. The first straight groove 21, the upper turning portion 23, the second straight groove 22 and the lower turning portion 24 are connected in sequence to form an oblong annular structure and form an annular slide groove 25.

[0088] Specifically, the inner grooves of the first straight groove 21, the upper turning portion 23, the second straight groove 22 and the lower turning portion 24 have the same size and the same opening direction, and are connected in sequence to form an annular slide groove 25, which is used to cooperate with the sliding chain 4 to guide the sliding chain 4 in the direction of the predetermined trajectory, as well as to limit the position perpendicular to the direction of the predetermined trajectory; the upper turning portion 23 cooperates with the agent groove 71 of the chemical cleaning system 7 to guide the sliding chain 4 into the agent groove 71, and then drive the fishing net 3 to pass through the agent groove 71 for chemical cleaning.

[0089] Further, if Figure 6 As shown, the predetermined track of the upper turning portion 23 is wavy, which guides the fishing net 3 so that the fishing net 3 can interact with the cleaning device after reaching the upper end of the track 2.

[0090] Specifically, such as Figure 6 As shown, the local predetermined trajectory corresponding to the upper turning portion 23 is M-shaped, so that the single net portion of the fishing net 3 is first bent upward and then bent downward at a position that is highly consistent with the upper turning portion 23, and then bent upward and then bent downward when interacting with the cleaning device; the cleaning device is specifically a chemical cleaning system 7, and the single net portion of the fishing net 3 is bent downward and immersed below the liquid level of the chemical cleaning system 7 tank 71, forming an upper detour portion 31 corresponding to the upper turning portion 23 on the upper part of the fishing net 3, as shown in FIG. Figure 1 shown.

[0091] In addition, the hypochlorous acid produced by electrolysis of seawater is unstable. The fishing net 3 comes into contact with the hypochlorous acid solution to remove microorganisms on the net. After the fishing net moves upward along the track 2, it is outside the chemical solution. The hypochlorous acid remaining on the fishing net is easily decomposed into hydrochloric acid and oxygen when exposed to light. Hydrochloric acid is volatile, so the chemically disinfected fishing net will not affect the growth of fish when it enters the water again, and is harmless to farmed fish.

[0092] Further, if Figure 3-Figure 10 As shown, the structure of the sliding chain 4 is as follows: it includes a plurality of first connecting members 41, one end of the first connecting member 41 is in sliding engagement with the track 2, the other end of the first connecting member 41 is connected to a single side edge of the end of the fishing net member 3, a plurality of second connecting members 42 are provided between two adjacent first connecting members 41, a single first connecting member 41 and a plurality of second connecting members 42 are connected in series to form a chain unit, and each second connecting member 42 is in sliding engagement with the track 2;

[0093] On the side of the chain unit opposite to the fishing net member 3 , the end of the first connecting member 41 and the ends of the plurality of second connecting members 42 form a transmission tooth structure, which is in transmission cooperation with the driving device 5 .

[0094] Specifically, the first connecting member 41 and the second connecting member 42 slide with the slide groove 25 in the track 2; multiple chain units are connected in series to form a sliding chain 4; the cross section of the track 2 is open at both ends at the transmission connection part between the driving device 5 and the sliding chain 4, such as Figure 7 As shown in (a), the cross section of the track 2 in other areas is a shape with one end open and the other end closed, as shown in FIG. Figure 7 As shown in (b);

[0095] The portion of the first connecting member 41 placed in the chute 25 and the second connecting member 42 are consistent with the inner cross-sectional shape of the chute 25, but are slightly smaller in size than the inner cross-sectional size of the chute 25, ensuring that the sliding chain 4 can move along the track 2 without falling off, while ensuring the shape of the fishing net so that the fishing net can be immersed in the drug solution of the drug tank 71 during the movement when passing through the drug tank 71; the cross-sectional dimensions of the first connecting member 41 and the second connecting member 42 are as follows: Figure 8 and Figure 9 As shown in (c) and (e);

[0096] like Figures 8-10 As shown, the connecting surfaces of the first connecting member 41 and the plurality of second connecting members 42 are provided with cylindrical grooves 411. The cylindrical grooves 411 realize the connection between the first connecting member 41 and the second connecting members 42 and the adjacent second connecting members 42 by cooperating with the two ends of the third connecting member 43. The two ends of the third connecting member 43 are cylindrical heads 431. The cylindrical heads 431 cooperate with the cylindrical grooves 411 to ensure relative rotation between adjacent units. The end of the first connecting member 41 is provided with a ring 412, and the ring 412 is connected to the single side of the end of the fishing net member 3.

[0097] Further, if Figure 3 、 Figure 5 As shown, a cabin 121 is provided on the frame structure 1 , and the driving device 5 includes a gear 51 , which is installed in the cabin 121 .

[0098] Specifically, such as Figure 2 、 Figure 3 As shown, the drive device 5 is located on both sides of a single fishing net member 3; the cabin 121 is located inside the column 12, the intersection surface of the cabin 121 and the interior of the column 12 is a closed structure, and the surface intersecting with the outer surface of the column 12 is an open structure, which not only ensures the watertightness of the column 12, but also enables the gear 51 and the sliding chain 4 to engage in the track 2; preferably, the cabin 121 is arranged in an area above the waterline to reduce possible corrosion caused by seawater; the drive device 5 also includes a motor for outputting power, which can be specifically installed inside the column 12 or located in the cabin 121, and the output end of the motor is connected to the gear 51 in a transmission manner.

[0099] During operation, the driving device 5 drives the gear 51 to rotate and then drives the sliding chain 4 to move in the track 2, driving the single net of the fishing net 3 from both ends to roll along a predetermined closed loop track, thereby realizing the self-rolling of the fishing net 3.

[0100] Example 2:

[0101] The method for operating a fishery cage capable of preventing the growth of marine organisms according to the first embodiment comprises the following steps:

[0102] Step 1: Determine the cleaning cycle of the fishing net 3;

[0103] The cleaning cycle is determined by the water conditions of the cage and can be set based on empirical values. The cleaning operation is automatically performed through the control system.

[0104] Step 2: During the biological cleaning operation, the control system controls the sinking and floating of the cage so that the physical cleaning system 6 and the chemical cleaning system 7 of the cleaning device are both located above the waterline;

[0105] Step 3: The control system starts the driving device 5 according to the set cleaning cycle, and at the same time adjusts the rolling speed of the fishing net 3 so that the fishing net on the outside of the net box rolls upward;

[0106] The fishing net 3 is a cylindrical structure, which is a flat cylindrical structure under the guidance and support of the track 2, so that the fishing net 3 can achieve the effect of a double-layer fishing net. The fishing net located on the outside of the net box is moved upward by the rolling of the fishing net 3 to expose the waterline surface and interact with the cleaning device.

[0107] Step 4: The physical cleaning system 6 is activated while the fishing net 3 is rolling to remove large marine organisms from the fishing net;

[0108] The high-pressure water gun 62 of the physical cleaning system 6 moves along the guide rail 61 and sprays high-pressure water to remove large marine organisms.

[0109] Step 5: After the large marine organisms are cleaned, the chemical cleaning system 7 is turned on, a chemical solution is added to the chemical cleaning system 7, and the driving device 5 is started to rotate the fishing net 3 and react with the chemical solution to remove the microorganisms on the fishing net.

[0110] The chemical cleaning operation can be performed after the fishing net 3 rotates one or half a circle. During the chemical cleaning operation, the fishing net 3 rotates at least one circle so that the fishing net of the fishing net 3 can come into contact with the chemical solution in the chemical tank 71.

[0111] An electrolytic box 72 is provided in the reagent tank 71, and a reagent solution containing hypochlorous acid is prepared in the reagent tank 71 using seawater as a raw material.

[0112] Before the chemical cleaning system 7 starts, seawater is pumped into the reagent tank 71 by the pump on the column 12. The concentration of the reagent solution in the reagent tank 71 is detected to control the start and stop of the electrolytic box 72 to prepare the reagent solution when the chemical cleaning system 7 is started.

[0113] The rolling system drives the fishing net 3 to roll, so that the net of the fishing net 3 is first cleaned by the physical cleaning system 6 to remove larger marine organisms on the fishing net, and then the chemical cleaning system 7 is used to remove microorganisms on the fishing net, thereby achieving the purpose of preventing the growth of marine organisms. The control system performs automated cleaning operations according to the cleaning cycle, realizes remote operation, reduces the maintenance cost of the cage, and improves work efficiency.

[0114] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any modifications may be made within the scope of protection of the present invention.
