[0014] As a preferred embodiment of the present invention, the following steps are included:

[0015] Install the device:

[0016] By fitting the device onto the outside of the aquaculture cage and then pushing the rotary bar to wind up the rope, multiple sets of fixed seats are brought closer together, thereby fixing the monitoring and control device to the outside of the cage. During this process, the floating platform is placed inside the cage.

[0017] Active feeding and oxygenation:

[0018] The system allows feed to be placed inside the tank. Waves propel the float to rotate the rocker arm, which in turn pushes air into the tank, causing the sliding plate to slide. During this process, the feed falls into the opening through the feed inlet and then slides out of the tank into the water. At the same time, the pipe is connected to the air outlet plate, allowing air to enter the plate and continuously rise from the water to the surface, dissolving oxygen in the water.

[0019] Automatic energy storage;

[0020] When the rocker arm rotates, it drives the drive gear to rotate, which in turn causes the generator to rotate and power the camera. Excess power is stored in the battery, ensuring that the camera has enough power when the wind and waves are small.

[0021] In summary, the present invention has the following main beneficial effects:

[0022] This invention, through the design of a fixed frame, utilizes the cooperation of the fixed seat, sleeve, inner tube, tightening mechanism, and rope of the fixed frame to enable the monitoring and control device to be installed conveniently and quickly. It also allows the monitoring and control device to be adapted to cages of different sizes, making the monitoring and control device more adaptable and improving the installation efficiency of construction personnel.

[0023] This invention designs a power mechanism that utilizes the coordinated operation of the rocker arm, float, support plate, airbag, slide, slider, connecting rod, second sliding frame, second slide, first check valve, and second check valve in the central power mechanism. This allows the monitoring and control device to be driven by the power of ocean waves during operation, eliminating the need for other power sources and thus achieving a more environmentally friendly and energy-saving purpose.

[0024] This invention designs a feeding and oxygenation mechanism. By utilizing the coordinated operation of the floating platform, storage tank, second spring, pipe, and air outlet plate of the feeding and oxygenation mechanism, the monitoring and control device, driven by the power mechanism, can achieve automatic feeding and oxygenation of the water inside the net cage. This reduces the labor intensity of aquaculture personnel and prevents fish from suffering from oxygen deficiency due to excessive stocking density. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0040] The embodiments of the present invention will now be described.

[0041] A smart monitoring and control device and method for aquaculture on a decommissioned oil and gas platform, such as Figures 1-9 As shown, it includes a fixed frame 1, a camera 2 fixedly connected to the top of the fixed frame 1, two sets of power mechanisms 3 fixedly connected to the top of the fixed frame 1, a feeding and oxygenation mechanism 4 fixedly connected to the inner wall of the fixed frame 1, the power mechanism 3 and the feeding and oxygenation mechanism 4 are connected, and two sets of energy storage mechanisms 5 fixedly connected to the side wall of the fixed frame 1, the two sets of energy storage mechanisms 5 are located next to the two sets of power mechanisms 3 respectively.

[0042] For details, please refer to the following: Figure 1 , Figure 4 , Figure 5 , Figure 6 The fixed frame 1 includes a fixed base 101, a sleeve 102, an inner tube 103, a tightening mechanism 104, and a rope 105. A sleeve 102 is fixedly connected to the side wall of each of the multiple fixed bases 101. An inner tube 103 is slidably connected to the inner wall of the sleeve 102. Another fixed base 101 is fixedly connected to one end of the inner tube 103 extending outside the sleeve 102. A tightening mechanism 104 is fixedly connected to the top of each of the multiple fixed bases 101. Two tightening mechanisms on the same side... The internal structure 104 has two ends of the same set of ropes 105 fixedly connected to it. The tightening mechanism 104 includes a housing 1041, scrapers 1042, a first spring 1043, a lever 1044, a connecting rod 1045, a reel 1046, a pushing assembly 1047, and a first gear set 1048. The housing 1041 is fixedly connected to the top of the fixed base 101. Two sets of scrapers 1042 are slidably connected to the inner wall of the housing 1041. The two sets of scrapers 1042 are respectively connected to the two ends of the same set of ropes 105. At the top and bottom ends of the 05, a set of No. 1 springs 1043 are fixedly connected to the ends of the two sets of scrapers 1042. The other end of the No. 1 springs 1043 is fixedly connected to the inner wall of the outer casing 1041. A paddle 1044 is slidably connected to the side wall of the outer casing 1041. One end of the paddle 1044 located inside the outer casing 1041 is hinged to one end of two sets of connecting rods 1045. The other ends of the two sets of connecting rods 1045 are respectively hinged to the side walls of the two sets of scrapers 1042. The inner wall of the outer casing 1041... A rotatable reel 1046 is connected to the wall. A ratchet device is provided at the connection between the reel 1046 and the outer shell 1041. A push assembly 1047 is fixedly connected to the inner wall of the outer shell 1041. A first gear set 1048 is provided on the inner wall of the outer shell 1041 between the push assembly 1047 and the reel 1046. One end of the first gear set 1048 is fixedly connected to the side wall of the push assembly, and the other end of the first gear set 1048 is fixedly connected to the outer wall of the ratchet device.

[0043] For details, please refer to the following: Figure 5The actuating assembly includes a bushing 10471, a rotating block 10472, a throttle 10473, a gear ring 10474, a gear disc 10475, a first sliding frame 10576, and a first sliding rod 10477. The bushing 10471 is fixedly connected to the inner wall of the outer casing 1041. The rotating block 10472 is rotatably connected to the side wall of the bushing 10471. The throttle 10473, extending to the outside of the outer casing 1041, is rotatably connected to the inner wall of the rotating block 10472. The throttle 10473 has a connection point with the rotating block 10472. A torsion spring is provided. A gear ring 10474 is fixedly connected to the inner wall of the bushing 10471. The side wall of the rotating block 10472 is slidably connected to the gear disk 10475 located inside the bushing 10471. The gear disk 10475 meshes with the gear ring 10474. A sliding frame 10576 is fixedly connected to one end of the gear disk 10475 located inside the rotating block 10472. A sliding rod 10477 is fixedly connected to the side wall of the handle 10473. The end of the sliding rod 10477 is slidably connected to the inner wall of the sliding frame.

[0044] Place the device outside the net cage, then rotate the handle 10473, causing the handle 10473 to move the first sliding frame 10576 via the first sliding rod 10477. This causes the first sliding frame 10576 to move the gear disc 10475, thus preventing the gear disc 10475 from meshing with the gear ring 10474. Then push the handle 10473 downwards, causing the handle 10473 to rotate the rotating block 10472. The rotating block 10472, through the first gear set 1048, drives the ratchet device to rotate. The ratchet mechanism drives the reel 1046 to rotate and wind up the rope 105. Then, the handle 10473 is lifted up. At this time, the ratchet mechanism will not drive the reel 1046 to rotate. The above action is repeated to make the rope 105 continuously wind up, so that multiple sets of fixed seats 101 are brought closer together, and the monitoring and control device is fixed to the outside of the cage. Then, the handle 10473 is released, so that the handle 10473 is reset under the action of the torsion spring, thereby making the handle 10473 drive the first sliding rod 10477 to reset.

[0045] At this time, the toothed disc 10475 engages with the toothed ring 10474, making it impossible to rotate, thereby preventing the rope 105 from loosening. The ratchet device mentioned in this invention is an existing and widely used device that can be used to limit the rotation direction of mechanical parts. During the installation of the monitoring device, the inner tube 103 continuously slides inside the sleeve 102, thereby continuously adapting to the distance between the fixed seats 101.

[0046] For details, please refer to the following: Figure 2The power mechanism 3 includes rocker arms 301, floats 302, support plates 303, airbags 304, slides 305, sliders 306, connecting rods 307, second sliding frames 308, second sliding rods 309, first one-way valves 310, and second one-way valves 311. One end of each of the two sets of rocker arms 301 is hinged to the side walls of two sets of fixed seats 101, and the other end of each set of rocker arms 301 is fixedly connected to a set of floats 302. The top of each fixed seat 101 is fixedly connected to two... A set of support plates 303 are provided, and an airbag 304 is slidably connected between the two sets of support plates 303. A set of sliding grooves 305 are respectively opened on the sidewalls of the two sets of support plates 303. Two sets of sliders 306 extending into the sliding grooves 305 are fixedly connected to the sidewalls of the airbag 304. One end of a connecting rod 307 is fixedly connected to the sidewall of the airbag 304, and the other end of the connecting rod 307 is fixedly connected to a second sliding frame 308. A second sliding rod 309 is slidably connected to the inner wall of the second sliding frame 308. One end of the second sliding rod 309 is fixedly connected to the top of the rocker arm 301. A one-way valve 310 is installed on the side wall of the airbag 304. The waves push the float 302 up and down, causing the rocker arm 301 to rotate. During the rotation of the rocker arm 301, the second sliding rod 309 rotates, causing it to push the connecting rod 307 through the second sliding frame 308. This causes the connecting rod 307 to push the airbag 304 to contract or expand. When the rocker arm 301... When the rocker arm 301 flips downwards, it causes the airbag 304 to expand. When the rocker arm 301 flips upwards, it causes the airbag 304 to contract. When the airbag 304 expands, the internal pressure of the airbag 304 decreases, causing the first one-way valve 310 to open and the second one-way valve 311 to be tightly attracted to the side wall of the airbag 304. At this time, air enters the airbag 304 through the first one-way valve 310. When the airbag 304 contracts, it pushes the air inside, causing the first one-way valve 310 to close and the second one-way valve 311 to open.

[0047] For details, please refer to the following: Figure 3 , Figure 7 and Figure 8The feeding and oxygenation mechanism 4 includes a floating platform 401, a storage tank 402, a pipe 403, and an air outlet plate 404. A set of fixed bases 101 are fixedly connected to the side wall of the floating platform 401. The top of the floating platform 401 is fixedly connected to the storage tank 402. The side wall of the air bladder 304 is connected to one end of the pipe 403, and the other end of the pipe 403 extends into the storage tank 402. A second one-way valve 311 is provided at the connection point between the air bladder 304 and the pipe 403. The bottom of the storage tank is connected to an air outlet plate 404 extending below the floating platform 401. The storage tank 402 includes a body 4021, a discharge port 4022, a sliding plate 4023, an opening 4024, a baffle 4025, and a second spring 4026. The body 4021 is fixedly connected to the top of the floating platform 401. One end of the pipe 403 extends into the body 4021, and the air outlet plate is connected to the side wall of the air bladder 402. At the bottom of box 4021, a feeding port 4022 is provided at the bottom of the inner wall of box 4021. A sliding plate 4023 is slidably connected to the bottom of the inner wall of box 4021. An opening 4024 is provided at the top of sliding plate 4023. A baffle 4025 is fixedly connected to the top of sliding plate 4023. One end of a second spring 4026 is fixedly connected to the side wall of baffle 4025. The other end of the second spring 4026 is fixedly connected to the inner wall of box 4021. Air inside airbag 304 enters pipe 403 through second one-way valve 311, and then enters the inside of box 4021. After the air enters the inside of box 4021, it pushes sliding plate 4023 to slide out of box 4021. When opening 4024 is connected to feeding port 4022 under the action of sliding plate 4023, feed falls into opening 4024 and slides along sliding plate 4023.

[0048] When the opening 4024 slides out of the box 4021, the feed falls into the water from the opening 4024. At this time, the sliding plate 4023 no longer blocks the air outlet plate 404, allowing air to enter the air outlet plate 404. This allows the air to rise from the bottom of the water to the surface through the air outlet plate 404, achieving the effect of oxygenation. When the air enters the air outlet plate 404, the air pressure between the sliding plate 4023 and the line body decreases. At this time, the spring pushes the baffle 4025, thereby driving the sliding plate 4023 to slide into the box 4021.

[0049] For details, please refer to the following: Figure 9The energy storage mechanism 5 includes a sealed housing 501, a drive gear 502, a rotating shaft 503, a crown gear 504, a second gear set 505, a generator 506, and a battery 507. The sealed housing 501 is fixedly connected to the side wall of the fixed base 101. The drive gear 502 is rotatably connected to the inner wall of the sealed housing 501. One end of the drive gear 502 located outside the sealed housing 501 is fixedly connected to the hinge between the rocker arm 301 and the fixed base 101. The rotating shaft 503 is rotatably connected to the inner wall of the sealed housing 501. The crown gear 504 is fixedly connected to the outer wall of the rotating shaft 503. The crown gear 504 is connected to the drive gear 506. The drive gear 502 meshes, and one end of the shaft 503 is fixedly connected to one end of the second gear set 505. Two generators 506 are fixedly connected to the inner wall of the sealing shell 501. The two generators 506 are respectively connected to the shaft 503 through the second gear set 505. A battery 507 sleeved on the outside of the generator 506 is fixedly connected to the inner wall of the sealing shell 501. When the rocker arm 301 flips up and down, it drives the drive gear 502 to rotate. The starting gear drives the shaft 503 to rotate through the crown gear 504. The shaft 503 drives the generator 506 to rotate through the second gear set 505, thereby generating electrical energy.

[0050] Based on the above conditions, the specific design scheme using this approach is as follows:

[0051] The buoy 302 is pushed up and down by the waves, causing the rocker arm 301 to flip. During the flipping of the rocker arm 301, the second sliding rod 309 also flips, causing the second sliding rod 309 to push the connecting rod 307 to move through the second sliding frame 308. This causes the connecting rod 307 to push the airbag 304 to contract or expand. When the rocker arm 301 flips downward, it causes the airbag 304 to expand; when the rocker arm 301 flips upward, it causes the airbag 304 to contract. When the airbag 304 expands, the internal pressure of the airbag 304 decreases, causing the first one-way valve 310 to open and the second one-way valve 311 to be tightly adhered to the side wall of the airbag 304. At this time, air enters the airbag 304 through the first one-way valve 310. When the airbag 304 contracts, it pushes the air inside, causing the first one-way valve 310 to close and the second one-way valve 311 to open. At this time, the air inside the airbag 304 enters the pipe 403 through the second one-way valve 311, and then enters the box 4021. After the air enters the box 4021, it pushes the sliding plate 4023 to slide out of the box 4021. When the opening 4024 is connected to the feed inlet 4022 under the action of the sliding plate 4023, the feed falls into the opening 4024 and slides along the sliding plate 4023.

[0052] When the opening 4024 slides out of the box 4021, the feed falls into the water from the opening 4024. At this time, the sliding plate 4023 no longer blocks the air outlet plate 404, allowing air to enter the air outlet plate 404. This allows the air to rise from the bottom of the water to the surface through the air outlet plate 404, achieving the effect of oxygenation. When the air enters the air outlet plate 404, the air pressure between the sliding plate 4023 and the line body decreases. At this time, the spring pushes the baffle 4025, thereby causing the sliding plate 4023 to slide into the box 4021. The above process is repeated continuously, thereby realizing active feeding and automatic oxygenation. When the rocker arm 301 flips up and down, it drives the drive gear 502 to rotate. The starting gear drives the rotating shaft 503 to rotate through the crown gear 504. The rotating shaft 503 drives the generator 506 to rotate through the second gear set 505, thereby generating electrical energy.

[0053] When installing the monitoring and control device, the device is placed outside the cage. Then, the handle 10473 is rotated, causing the handle 10473 to move the first sliding frame 10576 via the first sliding rod 10477. This causes the first sliding frame 10576 to move the gear disc 10475, thus preventing the gear disc 10475 from meshing with the gear ring 10474. Then, the handle 10473 is pushed downwards, causing the handle 10473 to rotate the rotating block 10472. The rotating block 10472 drives the ratchet via the first gear set 1048. The device rotates, causing the ratchet mechanism to drive the reel 1046 to rotate and wind up the rope 105. Then, the handle 10473 is lifted upwards. At this time, the ratchet mechanism will not drive the reel 1046 to rotate. The above actions are repeated continuously, causing the rope 105 to be wound up continuously, thereby bringing multiple sets of fixed seats 101 closer together and fixing the monitoring and control device to the outside of the cage. Then, the handle 10473 is released, causing the handle 10473 to reset under the action of the torsion spring, thereby causing the handle 10473 to drive the first sliding rod 10477 to reset.

[0054] At this time, the toothed disc 10475 engages with the toothed ring 10474, making it impossible to rotate, thereby preventing the rope 105 from loosening. The ratchet device mentioned in this invention is an existing and widely used device that can be used to limit the rotation direction of mechanical parts. During the installation of the monitoring device, the inner tube 103 continuously slides inside the sleeve 102, thereby continuously adapting to the distance between the fixed seats 101.

[0055] When using it, the following steps are included:

[0056] Install the device:

[0057] By attaching the device to the outside of the aquaculture cage and then pushing the rotary bar to wind up the reel 1046 to wind up the rope 105, multiple sets of fixing seats 101 are brought closer together, thereby fixing the monitoring and control device to the outside of the cage. During this process, the floating platform 401 is placed inside the cage.

[0058] Active feeding and oxygenation:

[0059] The feed is placed inside the container 4021. The waves push the float 302 to rotate the rocker arm 301, which in turn causes the airbag 304 to continuously push air into the container 4021, thereby pushing the sliding plate 4023 to slide. During this process, the feed falls into the opening 4024 through the feed inlet 4022 and then slides out of the container 4021 through the opening 4024, causing the feed to fall into the water. At this time, the pipe 403 is connected to the air outlet plate 404, allowing air to enter the air outlet plate 404. This causes the air to continuously rise from the water to the surface, allowing the oxygen in the air to dissolve in the water.

[0060] Automatic energy storage;

[0061] When the rocker arm 301 flips, it drives the drive gear 502 to rotate, which in turn causes the generator 506 to rotate and supply power to the camera 2. Excess power is stored in the battery 507, thus ensuring that the camera 2 has sufficient power supply when the wind and waves are small.
