Description
Technical Field
[0001] This utility model belongs to the field of aquaculture cage technology, specifically relating to an escape-proof aquaculture cage with self-cleaning function. Background Technology
[0002] Aquaculture cages are crucial equipment in modern aquaculture, and the cleanliness of their nets directly affects the water exchange efficiency, internal water quality, and the health and growth rate of farmed organisms. In actual aquaculture, the netting easily accumulates algae, shellfish, barnacles, and other biological pollutants and organic impurities. These deposits clog the mesh, hindering water exchange between the inside and outside of the cage. This leads to a series of water quality deterioration problems, such as decreased dissolved oxygen and the accumulation of harmful substances like ammonia nitrogen, severely restricting aquaculture yields and even causing fish diseases and mortality.
[0003] To address the problem of clogged net cages, existing technologies mainly employ methods such as manual cleaning, high-pressure water jet rinsing by boat, or the installation of simple scrubbing devices. Manual cleaning is inefficient, labor-intensive, and poses safety hazards; high-pressure water jet rinsing by boat is costly, difficult to thoroughly and evenly clean the inside of the net cage, and improper operation can easily damage the netting. Additionally, there have been attempts to install fixed or simple rotating nozzles inside the net cage, but these methods often leave cleaning blind spots, failing to thoroughly clean the entire inner surface of the net cage.
[0004] On the other hand, to prevent farmed fish from escaping, aquaculture cages typically employ double or even multiple layers of mesh, which further increases the difficulty of cleaning. Traditional cleaning methods struggle to efficiently and thoroughly clean the inner mesh walls without compromising the escape-prevention function.
[0005] To address this, we propose an escape-proof aquaculture cage with a self-cleaning function. This device not only prevents escape but also ensures thorough cleaning through spiral motion and effectively removes contaminants with high-pressure water flow. Utility Model Content
[0006] The purpose of this invention is to provide an escape-proof aquaculture net cage with a self-cleaning function. This device not only has an escape-proof function, but also ensures thorough cleaning with spiral motion and effectively removes dirt with high-pressure water flow.
[0007] The specific technical solution adopted by this utility model is as follows:
[0008] An escape-proof aquaculture cage with self-cleaning function includes a cylindrical inner net and a cylindrical outer main net fitted over it. A floating plate is provided on the top of the cylindrical outer main net, and a cleaning component is provided on the top of the floating plate.
[0009] The cleaning assembly includes a bracket and a high-pressure micro water pump mounted on top of the floating disc. A rotating component is mounted on the bracket, and a hollow rotating shaft is installed on the rotating component. An elastic component is located inside the hollow rotating shaft, and a connecting rod is mounted on the elastic component. A second slider is mounted on one end of the connecting rod. A spiral track is fixedly mounted on the inner wall of the cylindrical inner mesh, and the second slider slides inside the spiral track. A hollow cylinder is fixedly mounted at the bottom of the elastic component, and a connecting hose is rotatably mounted at the bottom of the hollow cylinder. One end of the connecting hose is connected to the high-pressure micro water pump, and a connecting pipe is located on the outside of the hollow cylinder, communicating with it. A high-pressure nozzle is mounted at one end of the connecting pipe.
[0010] Furthermore, the aperture of the cylindrical outer mesh is smaller than the aperture of the cylindrical inner mesh.
[0011] Furthermore, the rotating assembly includes a waterproof reciprocating stepper motor fixedly mounted on the bracket, and the output end of the waterproof reciprocating stepper motor is connected to the hollow rotating shaft.
[0012] Furthermore, the elastic component includes a spring disposed inside the hollow rotating shaft, a sliding disk disposed at the bottom of the spring, a moving rod disposed at the bottom of the sliding disk, and the bottom of the moving rod passing through the hollow rotating shaft and connected to the connecting rod.
[0013] Furthermore, a first sliding groove is provided on the inner wall of the hollow rotating shaft, and a first slider is provided inside the first sliding groove. One side of the first slider is connected to the sliding disk.
[0014] Furthermore, the second slider is matched with the spiral track.
[0015] Furthermore, the second slider, the spiral track, the high-pressure nozzle, the connecting rod, and the outer side of the hollow cylinder are all provided with an anti-corrosion layer.
[0016] The technical effects achieved by this utility model are as follows:
[0017] When the cleaning function is activated, the high-pressure micro water pump starts working, drawing water from an external or internal water source in the net cage and delivering high-pressure water to the hollow cylinder through a connecting hose. The water then exits through a connecting pipe and is sprayed from the high-pressure nozzle. Simultaneously, a rotating component drives the hollow shaft to rotate, which in turn rotates the connecting rod and the hollow cylinder. The connecting rod moves the second slider on a spiral track. Due to the spiral design of the track, the sliding of the second slider causes the hollow cylinder to rotate while simultaneously moving downwards through an elastic component. Because the hollow cylinder is rotatably connected to the connecting hose, the hollow cylinder rotates while the connecting hose remains stationary. The hollow cylinder then drives the connecting pipe, causing the high-pressure nozzle to rotate. During the rotation and movement of the hollow cylinder, the high-pressure nozzle continuously sprays high-pressure water jets. These water jets impact the inner wall of the cylindrical inner net, effectively removing algae, dirt, or other blockages adhering to the net surface, keeping the mesh clear, and preventing the net cage from accumulating dirt and affecting water quality or fish health. This device not only has an escape-prevention function, but the spiral motion also ensures thorough cleaning without blind spots, and the high-pressure water flow effectively removes dirt.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0025] like Figures 1-4As shown, an escape-proof aquaculture cage with self-cleaning function includes a cylindrical inner net 1 and a cylindrical main outer net 2 fitted outside it. A floating plate 3 is provided on the top of the cylindrical main outer net 2, and a cleaning component is provided on the top of the floating plate 3.
[0026] The cleaning assembly includes a bracket 4 and a high-pressure micro water pump 5 mounted on top of the floating disc 3. A rotating component is mounted on the bracket 4, and a hollow rotating shaft 6 is mounted on the rotating component. An elastic component is installed inside the hollow rotating shaft 6, and a connecting rod 7 is mounted on the elastic component. A second slider 8 is mounted on one end of the connecting rod 7. A spiral track 9 is fixedly mounted on the inner wall of the cylindrical inner net 1. The second slider 8 slides inside the spiral track 9. A hollow cylinder 10 is fixedly mounted at the bottom of the elastic component. A connecting hose 11 is rotatably mounted at the bottom of the hollow cylinder 10. One end of the connecting hose 11 is connected to the high-pressure micro water pump 5, and a connecting pipe 12 is provided on the outside of the hollow cylinder 10 to communicate with it. A high-pressure nozzle 13 is mounted on one end of the connecting pipe 12.
[0027] The diameter of the outer cylindrical mesh 2 is smaller than that of the inner cylindrical mesh 1, which is designed to prevent escape.
[0028] Meanwhile, the rotating component includes a waterproof reciprocating stepper motor 14 fixedly mounted on the bracket 4. The output end of the waterproof reciprocating stepper motor 14 is connected to the hollow rotating shaft 6, and the hollow rotating shaft 6 is driven to rotate by the waterproof reciprocating stepper motor 14.
[0029] Furthermore, for the waterproof reciprocating stepper motor 14, you can choose products from Oriental Electric Japan: the AZ series and PK series both have IP65-rated products, such as the AZD-KD model motor, which is existing technology and will not be discussed in detail here.
[0030] The elastic component includes a spring 15 disposed inside the hollow rotating shaft 6. A sliding disk 16 is disposed at the bottom of the spring 15. A moving rod 17 is disposed at the bottom of the sliding disk 16. The bottom of the moving rod 17 passes through the hollow rotating shaft 6 and is connected to the connecting rod 7. When the second slider 8 rotates on the spiral track 9, it drives the connecting rod 7 to move downward. The connecting rod 7 drives the moving rod 17 to stretch the spring 15 by the sliding disk 16, thereby causing displacement.
[0031] Furthermore, a first groove 18 is provided on the inner wall of the hollow rotating shaft 6, and a first slider is provided inside the first groove 18. One side of the first slider is connected to the sliding disk 16. This arrangement allows the moving rod 17 to drive the sliding disk 16 to move only in a straight line downwards.
[0032] The second slider 8 is matched with the spiral track 9. This arrangement allows it to move smoothly without jamming.
[0033] The bottom of the hollow cylinder 10 is rotatably equipped with a connecting hose 11. The connection method here is through a rotary joint. The rotary joint is a special mechanical sealing device designed to provide a continuous and leak-free connection when fluid (water, oil, gas) is transferred from a stationary pipe to the rotating part. It is existing technology and will not be described in detail here.
[0034] The second slider 8, the spiral track 9, the high-pressure nozzle 13, the connecting rod 7, and the hollow cylinder 10 are all provided with an anti-corrosion layer on their outer side, which can improve their service life.
[0035] The high-pressure micro water pump 5 is a micro high-pressure plunger pump, which is existing technology and will not be discussed in detail here.
[0036] The working principle of this utility model is as follows: When the cleaning function is activated, the high-pressure micro water pump 5 starts working, drawing water from a water source outside or inside the mesh cage, and delivering the high-pressure water to the hollow cylinder 10 through the connecting hose 11. Then, the water is sprayed out from the high-pressure nozzle 13 through the connecting pipe 12. At the same time, the rotating component drives the hollow rotating shaft 6 to rotate, which in turn drives the connecting rod 7 and the hollow cylinder 10 to rotate. The connecting rod 7 drives the second slider 8 to move on the spiral track 9. Due to the spiral design of the spiral track 9, the sliding of the second slider 8 causes the hollow cylinder 10 to move... While rotating, the device moves downwards via the elastic component. Simultaneously, due to the rotating connection between the hollow cylinder 10 and the connecting hose 11, the hollow cylinder 10 rotates while the connecting hose 11 remains stationary. The hollow cylinder 10 drives the connecting pipe 12, causing the high-pressure nozzle 13 to rotate. During the rotation and movement of the hollow cylinder 10, the high-pressure nozzle 13 continuously sprays high-pressure water jets. These water jets impact the inner wall of the cylindrical inner net 1, effectively removing algae, dirt, or other blockages attached to the net surface, keeping the mesh clear, and preventing the net cage from accumulating dirt and affecting water quality or fish health. This device not only has an escape prevention function, but the spiral motion also ensures thorough cleaning without dead angles, and the high-pressure water flow effectively removes dirt.
[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
