Description

Technical Field

[0001] This invention relates to the field of marine cage aquaculture equipment technology, specifically a monitoring device for the status of yellowfin tuna cage aquaculture. Background Technology

[0002] The yellowfin tuna cage culture status monitoring device is the core equipment for intelligent deep-sea aquaculture. Its main operation mode relies on a comprehensive sensing system that integrates underwater acoustic detection, optical vision and various water quality sensors. Through wireless transmission technology, it transmits the collected data on fish population, individual size, distribution behavior, net integrity and environmental data back to the shore or cloud platform in real time. It also uses artificial intelligence algorithms to analyze the data to achieve automated and intelligent management of growth assessment, precise feeding decisions, disease early warning and risk alarm.

[0003] Generally, yellowfin tuna cage culture monitoring devices work by installing a waterproof camera at the bottom of a buoy to monitor the fish's rearing status inside the cage. The buoy moves randomly within the cage due to sea breezes and waves, thus expanding the monitoring range. However, because the buoy's movement is synchronized with the sea breeze and waves, when the buoy is pushed by the waves, the resulting waves cause the buoy to undulate and tilt. At this time, the waterproof camera at the bottom moves synchronously with the buoy, which can easily lead to blurry images when the buoy shakes or tilts, thus reducing the stability of the monitoring device. Summary of the Invention

[0004] The purpose of this invention is to provide a monitoring device for the cage culture status of yellowfin tuna, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a monitoring device for the status of yellowfin tuna cage aquaculture, comprising a main body and a waterproof camera, and further comprising:

[0007] The maintaining mechanism is installed at the bottom of the main body. The operation of the maintaining mechanism can create a certain suction force on the water surface.

[0008] The cleaning mechanism is installed at the bottom of the maintaining mechanism. When the cleaning mechanism is in operation, it can drive the surrounding liquid to flow.

[0009] Furthermore, the main body includes:

[0010] The power unit, located at the top of the main body, provides power to the waterproof camera at the bottom.

[0011] Furthermore, the maintaining agencies include:

[0012] The swing component is located at the bottom of the main body, and its stability can be monitored during operation.

[0013] The deflector component is located on the outer surface of the main body.

[0014] Furthermore, the cleanup agencies include:

[0015] A flushing component is located at the bottom of the oscillating component;

[0016] The water-catching component is located on top of the flushing component. The operation of the water-catching component can reduce the rotation of the main body when it moves.

[0017] Furthermore, the energy components include four photovoltaic panels fixedly connected to the top of the main body, with the four photovoltaic panels distributed circumferentially around the main body.

[0018] Furthermore, the swing assembly includes a connecting column rotatably connected to the bottom of the main body, and a control plate is slidably connected to the outer surface of the connecting column;

[0019] Several springs are fixedly connected to the top of the control panel, and these springs are distributed in a circle around the connecting column.

[0020] A collection tube is provided at the bottom of the spring, and the top of the collection tube is fixedly connected to the bottom of the control panel;

[0021] The top of the waterproof camera is fixedly connected to the collection tube.

[0022] Furthermore, the driving component includes a rotating groove fixedly connected to the outer surface of the main body, and a sliding ring is slidably connected inside the rotating groove;

[0023] Three fan blades are fixedly connected to the side of the sliding ring away from the main body, and the three fan blades are distributed circumferentially around the rotating groove;

[0024] A barrier ring is installed at the end of the fan blade away from the photovoltaic panel, and the barrier ring is slidably connected to the inside of the rotating groove.

[0025] Furthermore, the driving-off component includes several activation plates fixedly connected to the bottom of the barrier ring, with the activation plates distributed circumferentially around the connecting post;

[0026] A second spring is fixedly connected to the side wall of the starter plate, and the top of the second spring is fixedly connected to the bottom of the main body.

[0027] The top of the second spring is provided with several rubber blocks, which are distributed circumferentially around the connecting post. The bottom of the rubber blocks is fixedly connected to the top of the barrier ring.

[0028] Furthermore, the flushing assembly includes a push block slidably connected to the outer surface of the collection cylinder, a water collection plate slidably connected to the side wall of the push block, and the water collection plate being fixedly connected to the bottom of the waterproof camera.

[0029] The bottom of the water collection plate has several flushing ports, which are distributed in a circle around the collection cylinder.

[0030] Among them, the outer surface of the push block is slidably connected with several connecting rods, which are distributed circumferentially around the collecting cylinder. The end of the connecting rod away from the push block is fixedly connected to the bottom of the fan blade.

[0031] Furthermore, the water-catching assembly includes a sliding plate slidably connected to the outer surface of the collection cylinder, and several rubber plates are fixedly connected to the top of the sliding plate. The rubber plates are distributed in pairs around the connecting column in a circular pattern.

[0032] A waterproof cloth is fixedly connected between the two rubber sheets.

[0033] The present invention has the following beneficial effects:

[0034] 1. In this invention, the control plate, due to the adsorption force formed between its bottom and the sea surface, causes the connecting column inside the control plate to rotate under the control plate's influence, keeping the waterproof camera at the bottom of the collection tube perpendicular to the sea surface. When the main body is lifted by waves and fluctuates up and down, the control plate will first follow the main body's up and down movement. At this time, the top of the control plate will be obstructed by the seawater, creating resistance. Under the influence of this resistance, the control plate will move downward relative to the main body's position. The design of the control plate reduces the displacement and shaking of the waterproof camera caused by the main body being affected by waves, thereby improving the stability of cage aquaculture status monitoring.

[0035] 2. In this invention, the horizontal plane of the control board will gradually become parallel to the bottom surface of the main body. At the same time, since the sea breeze stops, the main body will not move on the sea surface. The barrier ring will be reset under the pull of the second spring. The fan blade will be fixed after the barrier ring is reset. The fan blade can reduce the possibility of causing any damage to the fish when the main body moves on the sea surface. At the same time, it can reduce the reduction of the field of view of the waterproof camera when the main body moves closer to the fish, thereby improving the detection coverage when monitoring the status of net cage aquaculture.

[0036] 3. In this invention, the push block and the water-collecting plate are closely fitted. When the push block moves away from the water-collecting plate, the interior of the water-collecting plate is quickly filled with seawater by the pressure of the ocean. When the control plate is reset, the push block slides downward. At this time, the push block will squeeze the seawater inside the water-collecting plate. The seawater will be guided by the flushing port to flush the surface of the waterproof camera. Due to the setting of the water-collecting plate, the situation where the waterproof camera is attached to the inner surface of the ocean for a long time and the shooting quality is reduced is reduced. This further improves the clarity of detection when monitoring the status of cage aquaculture.

[0037] 4. In this invention, when the fan blades start to rotate, the seawater forms a vortex and is diverted by the curvature of the fan blades. The diverted seawater impacts the waterproof cloth that is unfolded when the rubber plate deforms. Since the top of the rubber plate is fixedly connected to the bottom of the main body, the main body will rotate in the opposite direction to the vortex rotation under the impact of the seawater. Due to the waterproof cloth, the situation where the camera rotates synchronously due to the rotation of the main body 1 under the influence of the vortex can be reduced, further improving the controllability of the detection direction when monitoring the status of cage aquaculture.

[0038] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] Please see Figure 1 - Figure 8 As shown, this invention is a monitoring device for the status of yellowfin tuna cage aquaculture, including a main body 1 and a waterproof camera 4, and also includes:

[0052] The maintaining mechanism 2 is installed at the bottom of the main body 1. The operation of the maintaining mechanism 2 can form a certain suction force on the water surface.

[0053] The cleaning mechanism 3 is installed at the bottom of the holding mechanism 2. When the cleaning mechanism 3 is in operation, it can drive the surrounding liquid to flow.

[0054] Entity 1 includes:

[0055] Energy component 11 is located on the top of the main body 1. The operation of energy component 11 can provide power to the bottom waterproof camera 4.

[0056] Maintenance mechanism 2 includes:

[0057] The swing component 21 is located at the bottom of the main body 1. The swing component 21 can detect stability when it is in operation.

[0058] The driving component 22 is disposed on the outer surface of the main body 1.

[0059] Cleanup organization 3 includes:

[0060] A flushing component 31 is disposed at the bottom of the swing component 21;

[0061] Water-catching component 32 is located on top of flushing component 31. The operation of water-catching component 32 can reduce the rotation of main body 1 when it moves.

[0062] The energy component 11 includes four photovoltaic panels 111 fixedly connected to the top of the main body 1. The four photovoltaic panels 111 are distributed in a circle around the main body 1. The main body 1 generates electricity and moves by means of waves formed by sunlight and sea breeze. The content captured by the waterproof camera 4 is transmitted to an external analysis instrument for analysis.

[0063] The swing assembly 21 includes a connecting column 211 rotatably connected to the bottom of the main body 1, and a control plate 212 slidably connected to the outer surface of the connecting column 211;

[0064] Several springs 213 are fixedly connected to the top of the control panel 212, and the springs 213 are distributed circumferentially around the connecting post 211.

[0065] A collection tube 214 is provided at the bottom of spring 213;

[0066] The top of the waterproof camera 4 is fixedly connected to the collection tube 214, and the top of the collection tube 214 is fixedly connected to the bottom of the control board 212. When the main body 1 is initially placed into the sea at a certain tilt angle, some seawater will enter the control board 212. When the bottom of the main body 1 is completely in contact with the sea surface, the control board 212 will be set with an arc at the top and bottom. There will be a certain amount of air inside the curved bottom of the control board 212. At this time, the bottom of the control board 212 will form a certain adsorption with the seawater.

[0067] The driving component 22 includes a rotating groove 221 fixedly connected to the outer surface of the main body 1, and a sliding ring 222 is slidably connected inside the rotating groove 221;

[0068] Three fan blades 223 are fixedly connected to the side of the sliding ring 222 away from the main body 1. The three fan blades 223 are distributed circumferentially around the rotating groove 221.

[0069] A baffle ring 224 is provided at the end of the fan blade 223 away from the photovoltaic panel 111. The baffle ring 224 is slidably connected to the inside of the rotating groove 221. When the main body 1 is initially placed into the sea at a certain tilt angle, the control plate 212 will enter some seawater. The movement of the control plate 212 will push the baffle ring 224 to slide downward relative to the main body 1 through the start plate 225. The sliding of the baffle ring 224 will cause the top rubber block 227 to move away from the bottom of the sliding ring 222 located inside the rotating groove 221.

[0070] The driving component 22 includes several activation plates 225 fixedly connected to the bottom of the barrier ring 224, and the several activation plates 225 are distributed circumferentially around the connecting post 211.

[0071] A second spring 226 is fixedly connected to the side wall of the starter plate 225, and the top of the second spring 226 is fixedly connected to the bottom of the main body 1.

[0072] The top of the spring 226 is provided with several rubber blocks 227, which are distributed circumferentially around the connecting post 211. The bottom of the rubber blocks 227 is fixedly connected to the top of the barrier ring 224. The sliding ring 222 will rotate under the push of the fan blade 223 by the sea breeze. Since part of the fan blade 223 is located inside the seawater, when the fan blade 223 rotates, it will form a vortex around the main body 1. Due to the formation of the vortex, the fish in the net cage will move away from the waterproof camera 4 under the influence of the vortex.

[0073] The flushing assembly 31 includes a push block 311 slidably connected to the outer surface of the collection cylinder 214, and a water collection plate 312 slidably connected to the side wall of the push block 311. The water collection plate 312 is fixedly connected to the bottom of the waterproof camera 4.

[0074] The bottom of the water collection plate 312 is provided with several flushing ports 313, which are distributed circumferentially around the collection cylinder 214.

[0075] Among them, the outer surface of the push block 311 is slidably connected with several connecting rods, which are distributed circumferentially around the collection cylinder 214. The end of the connecting rod away from the push block 311 is fixedly connected to the bottom of the fan blade 223. The movement of the control plate 212 will drive the collection cylinder 214 to move synchronously. At the same time, the push block 311 on the surface of the collection cylinder 214 slides towards the main body 1 relative to the connecting column 211. Since the length of the collection cylinder 214 does not change, the movement of the push block 311 will gradually move away from the water collection plate 312.

[0076] The water-catching component 32 includes a sliding plate 321 that is slidably connected to the outer surface of the collection cylinder 214. Several rubber plates 322 are fixedly connected to the top of the sliding plate 321. The rubber plates 322 are arranged in pairs around the connecting column 211.

[0077] A waterproof cloth 323 is fixedly connected between the two rubber plates 322. The push block 311 will push the top sliding plate 321 to move synchronously. The movement of the sliding plate 321 will cause the top rubber plate 322 to deform to a certain extent under the movement of the sliding plate 321 and the obstruction of the top main body 1.

[0078] In use, the staff fixes the photovoltaic panel 111 to the top of the main body 1, and then fixes the waterproof camera 4 to the bottom of the main body 1 through the collection tube 214. Then, the staff activates the photovoltaic panel 111 to convert photovoltaic power into electricity to power the waterproof camera 4 and puts the main body 1 into the water surface inside the cage. The main body 1 is powered and moved by the waves formed by sunlight and sea breeze. The content captured by the waterproof camera 4 is transmitted to the external analysis instrument for analysis, thereby completing the monitoring of the yellowfin tuna cage culture status.

[0079] When the main body 1 is placed on the sea surface, the bottom of the control plate 212 will be the first to contact the sea surface. Because the top and bottom of the control plate 212 are arc-shaped, when the main body 1 is initially placed at a certain angle, some seawater will enter the control plate 212. When the bottom of the main body 1 is fully in contact with the sea surface, due to the arc-shaped design of the top and bottom of the control plate 212, some air will be trapped inside the curved bottom. At this time, the bottom of the control plate 212 will form a certain degree of adhesion with the seawater, while the top of the control plate 212 will be completely filled with seawater. When sea breezes create waves, the waves will push the main body 1 to tilt. At this time, the control plate 212 will tilt due to the bottom contact with the seawater. The suction force formed by the sea surface causes the connecting column 211 inside the control plate 212 to rotate under the drive of the control plate 212, keeping the waterproof camera 4 at the bottom of the collection cylinder 214 perpendicular to the sea surface. When the main body 1 is lifted up and down by the waves, the control plate 212 will first follow the main body 1 and sway up and down. At this time, the top of the control plate 212 will be blocked by the seawater and generate resistance. Under the influence of the resistance, the control plate 212 will move downward relative to the position of the main body 1. The setting of the control plate 212 reduces the displacement and shaking of the waterproof camera 4 caused by the waves affecting the main body 1, which may lead to damage to the detection image, thereby improving the stability of cage aquaculture status monitoring.

[0080] When the control plate 212 deflects and moves up and down relative to the main body 1, the movement of the control plate 212 will push the baffle ring 224 to slide downward relative to the main body 1 via the starter plate 225. The sliding of the baffle ring 224 will cause the top rubber block 227 to move away from the bottom of the sliding ring 222 located inside the rotating groove 221, so that the sliding ring 222 will rotate under the push of the fan blade 223 by the sea breeze. Since the fan blade 223 is partially located inside the seawater, when the fan blade 223 rotates, it will form a vortex around the main body 1. Due to the formation of the vortex, the fish in the net cage will move away from the waterproof camera 4 under the influence of the vortex. As the sea breeze stops, the main body 1 gradually stabilizes, and the horizontal plane of the control plate 212 gradually becomes parallel to the bottom surface of the main body 1. At the same time, since the sea breeze stops, the main body 1 will not move on the sea surface. The barrier ring 224 will be reset under the pull of the spring 226. The fan blade 223 will be fixed after the barrier ring 224 is reset. The setting of the fan blade 223 can reduce the damage to the fish when the main body 1 moves on the sea surface. At the same time, it can reduce the reduction of the field of view of the waterproof camera 4 when the main body 1 gradually approaches the fish as it moves, thereby improving the detection coverage rate when monitoring the status of net cage aquaculture.

[0081] When the control plate 212 slides downward, its movement causes the collection cylinder 214 to move synchronously. At the same time, the push block 311 on the surface of the collection cylinder 214 slides towards the main body 1 relative to the connecting column 211. Since the length of the collection cylinder 214 does not change, the push block 311 will gradually move away from the water collection plate 312. Because the push block 311 is in close contact with the water collection plate 312, the interior of the water collection plate 312 will be quickly filled with seawater by the pressure of the ocean as the push block 311 moves away. When the control plate 212 is reset, the push block 311 will slide downward. At this time, the push block 311 will squeeze the seawater inside the water collection plate 312. The seawater will be guided by the flushing port 313 to flush the surface of the waterproof camera 4. Due to the setting of the water collection plate 312, the situation where the waterproof camera 4 is attached to the inner surface of the ocean for a long time, which reduces the image quality, is reduced, thereby further improving the clarity of the detection during the monitoring of the cage aquaculture status.

[0082] When the push block 311 slides upward, it pushes the top sliding plate 321 to move synchronously. The movement of the sliding plate 321 causes the top rubber plate 322 to deform under the influence of the movement of the sliding plate 321 and the obstruction of the top main body 1. Since the rubber plate 322 is already bent in its initial state, when it deforms, it will bend under the influence of its initial state. At this time, a gap will appear in the middle of the two tightly pressed rubber plates 322 under the influence of the deformation. When the fan blade 223 starts to rotate... When the water is in motion, the seawater forms a vortex and is diverted by the arc on the fan blade 223. The diverted seawater impacts the waterproof cloth 323 as the rubber plate 322 deforms. Since the top of the rubber plate 322 is fixedly connected to the bottom of the main body 1, the main body 1 will rotate in the opposite direction to the vortex rotation under the impact of the seawater. Due to the setting of the waterproof cloth 323, the situation of the camera rotating synchronously due to the rotation of the main body 1 under the influence of the vortex can be reduced, which further improves the controllability of the detection direction when monitoring the status of cage aquaculture.
