Description

Technical Field

[0001] This application relates to the field of motor technology, and more specifically, to a cage suspension and depth control driver. Background Technology

[0002] Depth control drive devices are core components of underwater facilities such as aquaculture cages and underwater observation equipment. Their main function is to precisely control the suspension depth of the equipment by adjusting the buoyancy and gravity balance of the device itself or the equipment it carries. In cage aquaculture, this device can flexibly adjust the depth of the cage in the water according to environmental factors such as water temperature, light, and water quality, providing a suitable growth environment for the cultured organisms while reducing the impact of wind and waves on the cages, ensuring the safety of aquaculture. Its performance directly affects the operational stability, control accuracy, and service life of the equipment, making it a key technological equipment for achieving intelligent and efficient operation of underwater facilities.

[0003] In existing technologies, the working principle of depth-controlled drive devices is mostly based on ballast adjustment, that is, adjusting the overall gravity by changing the amount of ballast water inside the device, thereby achieving lifting control. Common methods include: using a motor to drive a piston or screw structure, which moves the piston inside the ballast tank, thereby changing the volume of the ballast tank to achieve water intake or discharge. Some devices are equipped with simple sensors that monitor water depth data to control motor operation. The motor's heat dissipation design mostly relies on fixed heat sinks and natural convection within the closed cavity. Some devices in aquatic environments use ventilation holes to enhance air circulation and heat dissipation.

[0004] However, the existing motor structure of the depth control drive device has the following shortcomings:

[0005] When the upper part of the cage in the aforementioned existing depth-control drive device floats above the sea surface, the motor in the depth-control drive device will be exposed to the salt spray environment of the sea surface for a long time, which will easily cause the shell to rust and be damaged due to the electrochemical corrosion of the salt spray. When the cage is completely submerged in seawater, the motor will be in direct contact with seawater. However, the high salinity and ionic activity of seawater will exacerbate the corrosion failure of the shell. This will not only affect the performance and life of the motor, but also have an adverse effect on the stable operation of the entire depth-control drive device.

[0006] In view of this, we propose a cage suspension and depth control actuator that can adapt to multiple working environments. Summary of the Invention

When above water, the magnetic sealing plate retracts, allowing air circulation for heat dissipation; when underwater, the magnetic sealing plate inserts to form a water circulation loop, improving heat dissipation efficiency.

[0047] The drive mechanism includes a housing 200 fixed to the top surface of the ballast cylinder 110. A first gear plate 160 is connected through the housing 200. A motor assembly 300 is installed inside the housing 200. A reducer 400 is connected to one side of the motor assembly 300. A first rotating shaft 600 is connected to one side of the reducer 400. An encoder 700 is connected to one end of the first rotating shaft 600. A second gear 500 is sleeved and fixed to the outer wall of the first rotating shaft 600. One side of the second gear 500 is meshed with one side of the first gear plate 160. A secondary drive assembly 80 with a meshing rotation structure is installed inside the housing 200. 0. One side of the meshing rotation structure of the auxiliary drive assembly 800 is meshed with the other side of the first toothed plate 160. One end of the auxiliary drive assembly 800 is connected to the side wall of the motor assembly 300. The motor assembly 300 has a cavity structure with one side open. The opening of the cavity structure of the motor assembly 300 extends through the outside of the housing 200. The side wall of the housing 200 is provided with a sealing assembly 900 with a flipping structure. The sealing assembly 900 is used to close the opening of the cavity structure of the motor assembly 300 by flipping. The motor assembly 300 is electrically connected to the liquid level sensor 150 and the encoder 700.

[0048] The motor housing 310 of the motor assembly 300 adopts a cavity structure that runs through both sides. The guide frame 314 connects the cavity to the outside, allowing for direct ventilation and heat dissipation when above water and heat dissipation through contact with seawater when underwater. This balances ventilation above water and adaptability to underwater flow fields, improving the motor's heat dissipation efficiency and operational stability. The flip-type sealing assembly 900 on the side wall of the chassis 200 can seal the cavity opening of the motor assembly 300, preventing salt spray intrusion or seawater immersion when the motor is not working, thus mitigating the problem of salt spray or seawater corrosion.

[0049] Through the coordinated design of the ballast assembly 100 and the drive mechanism, the first piston 140 inside the ballast cylinder 110 engages with the second gear 500 and the auxiliary drive assembly 800 of the drive mechanism via the first toothed plate 160, achieving precise lifting and lowering to control pumping and drainage; the liquid level sensor 150 monitors the water level and the encoder 700 records the rotation data of the shaft, and the two work together to form feedback regulation, correcting the deviation of seawater volume and mass, and improving the depth-keeping accuracy; the double-sided meshing structure of the auxiliary drive assembly 800 enhances the transmission stability of the first toothed plate 160, ensuring the smooth lifting and lowering of the cage.

[0050] In this embodiment, the motor assembly 300 includes a motor housing 310 fixed inside the chassis 200. The motor housing 310 has a cavity structure that extends through both sides. An inner cylinder 315 that extends through both ends is fixed inside the cavity structure of the motor housing 310. A stator 320 is disposed inside the inner cylinder 315, and a rotor 330 is disposed inside the stator 320. One end of the rotor 330 extends through the outside of the motor housing 310, and the other end of the rotor 330 is connected to the inside of the reducer 400. An end cap 311 is fixed to the side wall. A guide frame 314 is connected through one side of the cavity structure of the motor housing 310. One side of the guide frame 314 is connected through to the outside of the chassis 200 and is sealed by the sealing assembly 900. A side cover 316 is fixed to the other side of the cavity structure of the motor housing 310. The side cover 316 has an arc-shaped structure. A heat-conducting cylinder 340 is sleeved on the outer wall of the inner cylinder 315. Multiple heat sinks 341 are fixed on the outer wall of the heat-conducting cylinder 340. The heat sinks 341 have an annular structure.

[0051] The motor housing 310 adopts a cavity structure that runs through both sides. The heat-conducting cylinder 340 and the annular heat sink 341 outside the inner cylinder 315 increase the heat dissipation area. When on water, it can be ventilated to the outside through the guide frame 314, improving the air heat dissipation efficiency. The arc-shaped structure of the side cover 316 reduces underwater water flow resistance. The guide frame 314 is sealed by the sealing assembly 900 to prevent salt spray from entering the cavity of the motor housing 310 when not in operation, solving the contradiction between sealing and heat dissipation in traditional motors, and taking into account both water protection and heat dissipation performance.

[0052] In this embodiment, the bottom height of the cavity structure of the motor housing 310 is less than the bottom height of the guide frame 314.

One end of the drain valve 313 is connected to a water outlet pipe 312, and the other end of the water outlet pipe 312 is connected through to the outside of the chassis 200. The bottom of the cavity of the motor housing 310 is lower than the guide frame 314, which facilitates the accumulation of water. The drain valve 313 and the water outlet pipe 312 work together to drain the seawater in the cavity in a timely manner, avoiding corrosion caused by long-term immersion of motor components in water. This structure solves the problem of difficult drainage of water in traditional motors, reduces the risk of component corrosion in underwater environments, and extends the service life of the motor.

[0054] The rotating push structure (impeller 352) of the flow guiding component 350, driven by the auxiliary drive assembly 800, promotes fluid circulation and enhances heat dissipation. The internal pressure magnetic push component 360 pushes the plug structure (magnetic sealing plate 354) into the cavity of the motor housing 310 according to the water pressure, realizing adaptive switching between above-water and underwater heat dissipation modes. When above water, the magnetic sealing plate 354 retracts, allowing air circulation for heat dissipation; when underwater, the magnetic sealing plate 354 inserts to form a water circulation loop, improving heat dissipation efficiency.

[0055] In this embodiment, the flow guiding component 350 includes a flow guiding box 351 that penetrates and connects to the outer wall of the side cover 316. Two opening structures are provided on one side of the flow guiding box 351, and the two opening structures of the flow guiding box 351 are respectively connected to the top and bottom of the side cover 316.

One end of each impeller 352 penetrates the outer wall of the flow guiding box 351, and a first gear 3521 is sleeved and fixed to one end of each impeller 352. The rotating end of the side drive assembly 800 is engaged with the side drive assembly 800; the insert structure includes a storage box 353 fixed to the outer wall of the flow guide box 351. One side of the storage box 353 is connected to the inside of the side cover 316. A magnetic sealing plate 354 is inserted inside the storage box 353. The magnetic sealing plate 354 is magnetically pushed by the internal pressure magnetic push component 360 so that the magnetic sealing plate 354 is inserted into the cavity structure of the motor housing 310. One side of the magnetic sealing plate 354 is a comb structure. The magnetic sealing plate 354 is snapped onto the outer wall of the heat sink 341 through the comb structure.

[0056] The double-opening design of the flow box 351, in conjunction with the impeller 352, enhances the circulation efficiency of air or seawater between the motor housing 310 and the flow box 351; the comb-tooth structure of the magnetic sealing plate 354 engages with the outer wall of the heat sink 341 to achieve precise flow channel blocking; the insert structure is driven by the internal pressure magnetic push component 360 to ensure a tight seal underwater and improve the effectiveness of heat dissipation circulation.

[0057] In this embodiment, a plurality of sealing sheets 3541 are fixed on one side of the comb structure of the magnetic sealing plate 354. The sealing sheet 3541 has an arc-shaped structure. The arc inner wall of the sealing sheet 3541 has the same arc as the arc outer wall of the heat conduction cylinder 340. The arc outer wall of the sealing sheet 3541 has the same arc as the arc inner wall of the side cover 316.

[0058] The arc-shaped sealing sheet 3541 on the comb structure of the magnetic sealing plate 354 matches the curvature of the outer wall of the heat conduction cylinder 340 and the inner wall of the side cover 316. When extending and retracting the storage box 353, it can maintain a tight fit, eliminate gaps, enhance the sealing of the flow channel, ensure that seawater flows efficiently in the circulation loop when underwater, and improve the heat dissipation effect.

[0059] In this embodiment, the internal pressure magnetic thrust component 360 includes a thrust cylinder 361 that penetrates and connects to the inside of the housing 200. One end of the thrust cylinder 361 is connected to the outside of the housing 200, and the other end of the thrust cylinder 361 is connected to an air pipe 367. One end of the air pipe 367 is connected to an exhaust valve 368, and one end of the exhaust valve 368 is connected to the cavity structure inside the motor housing 310. A second piston 362 is inserted inside the thrust cylinder 361. The second piston 362 is pushed and moved by external water pressure. One end of the second piston 362 is connected to a first connecting rod 363. The first connecting rod 363 penetrates the inside of the thrust cylinder 361 and one end extends outward to the top of the guide box 351. A sliding push is slidably sleeved on the outer wall of the first connecting rod 363. The frame 364 and the first push plate 3661 are provided. The bottom surface of the first push plate 3661 is fixed with a second toothed plate 366. One side of the second toothed plate 366 is connected through to the inside of the sealing assembly 900. The outer wall of the first connecting rod 363 is sleeved and fixed with a fixing ring 3632. The two ends of the fixing ring 3632 are respectively connected with a first spring 3631 and a second spring 3633. The end of the first spring 3631 away from the fixing ring 3632 is connected to the side wall of the sliding push frame 364. The two sides of the sliding push frame 364 are respectively slidably attached to the two sides of the flow guide box 351. The bottom surfaces of both sides of the sliding push frame 364 are fixed with magnetic plates 365. The magnetic plates 365 are attached to the side wall of the storage box 353. The two magnetic plates 365 are respectively magnetically connected to the two sides of the magnetic sealing plate 354.

[0060] The second piston 362 of the internal pressure magnetic thrust component 360 is pushed by water pressure, which drives the magnetic suction plate 365 to move the magnetic sealing plate 354 through the first connecting rod 363 and the sliding pusher 364, thus achieving automatic underwater sealing. The first spring 3631 and the second spring 3633 respectively control the sliding pusher 364 and the second toothed plate 366 to return to their original positions, ensuring that the magnetic sealing plate 354 retracts and the sealing assembly 900 opens when above water. The air pipe 367 cooperates with the exhaust valve 368 to force the air in the pressure thrust cylinder 361 into the cavity of the motor housing 310 underwater, assisting in the discharge of seawater. This solves the problem that traditional motors cannot automatically adapt to changes in water depth and switch states, thus improving environmental adaptability.

[0061] In this embodiment, the sealing assembly 900 includes a fixing box 950 fixed to the side wall of the chassis 200. A third rotating shaft 910 is rotatably connected to one side of the fixing box 950. One end of the third rotating shaft 910 is rotatably connected to the side wall of the chassis 200. A sealing plate 930 is fixed to the outer wall of the third rotating shaft 910. A fifth gear 920 and a sixth gear 940 are sleeved and fixed to the outer wall of the third rotating shaft 910. The top of the fifth gear 920 is meshed with the bottom surface of the second toothed plate 366. The sixth gear 940 is disposed inside the fixing box 950. A third toothed plate 960 is inserted into the top surface of the fixing box 950. One side of the third toothed plate 960 is meshed with the sixth gear 940. The third toothed plate 960 is disposed at the bottom of the baffle 161.

[0062] The third shaft 910 of the sealing assembly 900 drives the sealing plate 930 to rotate. Through the meshing transmission of the second toothed plate 366 and the fifth gear 920, and the third toothed plate 960 and the sixth gear 940, the guide frame 314 is automatically opened and closed. When the motor is not working or the predetermined depth is reached, the sealing plate 930 closes the guide frame 314 to prevent salt spray and seawater from entering; when working, it opens to ensure heat dissipation, solving the problem of inconvenient switching between traditional motor protection and heat dissipation, and further enhancing the protection effect on the motor.

[0063] In this embodiment, the auxiliary drive assembly 800 includes a support plate 820 fixed to the bottom surface inside the chassis 200. A second rotating shaft 830 is rotatably connected to one side of the support plate 820. One end of the second rotating shaft 830 is rotatably connected to the inner wall of the chassis 200. A fourth gear 840 is sleeved and fixed to the outer wall of the second rotating shaft 830. One side of the first gear 3521 is meshed with the first gear plate 160. A third gear 831 is sleeved and fixed to one end of the second rotating shaft 830. The third gear 831 is respectively meshed with the two first gears 840. A gear 3521 meshes with each other. A fixing plate 810 is fixed on the top surface of the support plate 820. One side of the fixing plate 810 is fixed to the inner wall of the chassis 200. A pressure resistance component 850 is installed through the inside of the fixing plate 810. The top of the pressure resistance component 850 extends through the top surface of the chassis 200. The pressure resistance component 850 is located between the baffle 161 and the second rotating shaft 830. The pressure resistance component 850 is pushed and adhered to the outer wall of the second rotating shaft 830 by the baffle 161 to reduce frictional speed of the second rotating shaft 830.

[0064] The fourth gear 840 and the second gear 500 of the auxiliary drive assembly 800 mesh with the two sides of the first toothed plate 160 respectively, and work with the third gear 831 to drive the impeller 352, thereby enhancing transmission stability. The piezoresistive component 850 pushes the second rotating shaft 830 through the baffle 161 to achieve frictional deceleration, improve the running accuracy and braking safety of the first toothed plate 160, and ensure the reliability of the cage depth control.

[0065] In this embodiment, the piezoresistive component 850 is slidably connected to the elastic telescopic rod 851 on the top surface of the chassis 200. The bottom end of the elastic telescopic rod 851 is connected to a second push plate 852. The bottom surface of the second push plate 852 is connected to two second connecting rods 853. The second connecting rods 853 are connected through the inside of the fixed plate 810. The two second connecting rods 853 are respectively spaced apart on both sides of the fourth gear 840. The bottom end of the second connecting rod 853 is connected to a brake pad 855. The brake pad 855 has an arc-shaped structure and is located on the top of the second rotating shaft 830. A third spring 854 is sleeved on the outer wall of the second connecting rod 853. The third spring 854 is located between the bottom surface of the fixed plate 810 and the top surface of the brake pad 855.

[0066] The elastic telescopic rod 851 and the third spring 854 push the brake pad 855 to fit tightly against the second rotating shaft 830, and the arc-shaped brake pad 855 increases the friction area; the two second connecting rods 853 are symmetrically distributed to ensure that the second rotating shaft 830 is evenly stressed on both sides of the fourth gear 840. This structure achieves smooth and efficient deceleration, improves braking accuracy, reduces wear on the brake pad 855, and extends the service life of the components.

[0067] Specifically, according to Figure 1 As shown, the net cage is suspended on the sea surface by the ballast cylinder 110 of the ballast assembly 100. The net cage is anchored at multiple points on the seabed by high-holding-force anchors connected by multiple anchor chains. Tension buoys are installed on the anchor chains to maintain a constant tension state. A central column is set in the middle of the net cage, and a suction anchor vertical tension system is set at the bottom of the net cage to provide vertical tension support. The suction anchor vertical tension system consists of a central mooring cable, a vertical winch, a suction anchor, a chain catcher, and connecting accessories. The lower end of the central mooring cable is connected to the suction anchor, and the upper end reaches the upper end of the central column through the anchor chain tube inside the central column. After passing through the chain catcher, it is connected to the vertical winch. The suction anchor penetrates into the seabed to form a fixed end and provides pull-out resistance. The raising and lowering of the net cage is controlled by adjusting the ballast water volume of the ballast assembly 100. Finally, the vertical winch controls the suspension depth of the net cage by adjusting the tension of the central mooring cable.

[0068] Then press Figure 2-13 As shown in the figure, the motor assembly 300 is initially positioned above the sea surface. The entire motor assembly 300 utilizes the enclosure 200 to provide a closed installation space. The internal cavity structure of the motor housing 310 is connected to the outside through the guide frame 314, allowing the interior of the motor assembly 300 to directly ventilate and dissipate heat from the outside. When the motor assembly 300 is positioned above the sea surface and not in operation for a long time, to prevent corrosion from sea salt spray, the motor assembly 300 drives the first toothed plate 160 to descend, causing the baffle 161 to push the third toothed plate 960, which meshes and drives the third rotating shaft 910 to rotate, causing the sealing plate 930 to flip and seal the guide frame 314, thus sealing the interior of the motor assembly 300. At the same time, the second toothed plate 366 moves into the enclosure 200 and compresses the second spring 3633.

[0069] The starting motor assembly 300 adjusts the ballast water volume of the ballast assembly 100 to lower the net cage. The baffle 161 rises with the first toothed plate 160 and separates from the third toothed plate 960. The compressed second spring 3633 pushes the second toothed plate 366 to move and drives the third rotating shaft 910 to rotate. The sealing plate 930 flips to open the guide frame 314. When the starting rotor 330 rotates inside the stator 320, the generated heat energy is directly transferred to the heat-conducting cylinder 340 through the inner cylinder 315 and utilized by the heat sink. 341 makes full contact with the air inside the cavity of the motor housing 310 and dissipates heat. At this time, the rotor 330 drives the reducer 400 to make the first rotating shaft 600 rotate. The first rotating shaft 600 drives the second gear 500 to rotate. The second gear 500 meshes and drives the first toothed plate 160 to rise. At the same time, the fourth gear 840 on the other side of the first toothed plate 160 also meshes with the first toothed plate 160, so that the first toothed plate 160 is driven on both sides, improving the transmission accuracy and the smoothness of the first toothed plate 160 rising.

[0070] The first toothed plate 160 pulls the first piston 140 inside the ballast cylinder 110 upwards, reducing the space at the top of the first piston 140. Air in the top space is discharged through the vent 111 connected to the air pipe 367. Seawater is pumped into the ballast cylinder 110 from the bottom of the first piston 140 using negative pressure and the water inlet valve 120. The increased weight inside the ballast cylinder 110 causes the net cage to sink. The water inlet valve 120 is a one-way valve with the flow direction facing the inside of the ballast cylinder 110. The encoder 700 records the rotation data of the first rotating shaft 600, thus indicating that the second gear 500 drives the first toothed plate 160 and the first piston. The rise height is 140, and the volume and mass of seawater pumped into the ballast cylinder 110 are calculated. At the same time, the liquid level sensor 150 at the bottom of the first piston 140 plate monitors the water level inside the ballast cylinder 110, calculates the actual volume and mass of seawater pumped into the ballast cylinder 110, and makes corrections and compensations based on the actual volume and mass of seawater pumped into the ballast cylinder 110. Based on the compensation data, the motor assembly 300 and the reducer 400 are controlled to continue driving the first rotating shaft 600 to rotate, so that water continues to be pumped into the ballast cylinder 110 until the mass of the pumped seawater causes the ballast cylinder 110 to drive the net cage to descend to the target depth.

[0071] During the meshing and rotation of the second gear 500 and the fourth gear 840 with the gear plate, the second rotating shaft 830 drives the third gear 831 to rotate. The third gear 831 meshes and rotates the two first gears 3521, causing the impeller 352 inside the guide box 351 to rotate rapidly, thereby allowing the air inside the guide box 351 and the cavity of the motor housing 310 to circulate rapidly, improving the heat dissipation effect of the motor assembly 300 during operation.

[0072] As the ballast cylinder 110 lowers the net cage into the water, the motor assembly 300, along with the cage 200, enters the sea. Seawater enters the motor housing 310 cavity and the guide box 351 through the guide frame 314, providing sufficient heat dissipation for the motor assembly 300. After entering the water, under the thrust of water pressure, the second piston 362 is pushed to move horizontally inside the push cylinder 361. The first connecting rod 363 pushes the fixed ring 3632 of the sliding push frame 364 to move horizontally, and the first spring 3631 pulls the sliding push frame 364 to move. The two magnetic plates 365 simultaneously use magnetic force to attract and push the magnetic seal. The plate 354 is inserted into the cavity structure of the motor housing 310. The sealing sheet 3541 on the magnetic sealing plate 354 is attached to the outer wall of the heat conduction cylinder 340. The comb structure of the magnetic sealing plate 354 is locked and sealed to the outer wall of the heat sink 341, thereby blocking the cavity structure of the motor housing 310. This allows a one-way water circulation loop to be formed between the cavity structure of the motor housing 310 and the interior of the flow guide box 351. In conjunction with the rotation of the impeller 352, seawater is rapidly circulated within the motor housing 310 and the flow guide box 351, improving the heat dissipation effect of the motor assembly 300 during the driving process in seawater.

[0073] As the motor assembly 300 continues to descend with the ballast cylinder 110 and is about to reach the predetermined long-term working depth, the water pressure further pushes the second piston 362 to move horizontally inside the push cylinder 361. The bottom connecting rod pushes the fixing ring 3632, and the second spring 3633 pushes the second toothed plate 366 to move, driving the sealing plate 930 to flip and close the guide frame 314, thus sealing the cavity structure of the motor housing 310. At the same time, the second piston 362 continues to move and pushes the air inside the push cylinder 361. The air enters the cavity structure of the motor housing 310 and the guide box 351 through the air pipe 367 and the exhaust valve 368, so that the seawater inside the cavity structure of the motor housing 310 and the guide box 351 is discharged through the drain valve 313 and the outlet pipe 312. The exhaust valve 368 and the drain valve 313 are both one-way valves to prevent backflow, so that the motor assembly 300 remains in a closed cavity structure after being in seawater and having stopped working for a long time, preventing corrosion caused by long-term immersion in seawater.

[0074] When the long-term aquaculture is completed and the net cage is raised, the motor unit is started to control the ballast cylinder 110 to rise, and the seawater inside the ballast cylinder 110 is discharged through the outlet valve 130. The outlet valve 130 is a one-way valve with the flow direction facing the outside of the ballast cylinder 110. The ballast cylinder 110 uses buoyancy to drive the net cage and motor assembly 300 to rise. Without the pushing action of seawater pressure, the second piston 362 pushes the sliding frame 364 to reset, the sealing plate 930 flips open to ventilate and dissipate heat, and the magnetic suction plate 365 drives the magnetic sealing plate 354 to retract into the storage box 353.

[0075] As the first toothed plate 160 descends and is about to allow the ballast cylinder 110 to complete the discharge of seawater, the baffle 161 stops and pushes the elastic telescopic rod 851 to insert into the housing 200. The elastic telescopic rod 851 elastically pushes the second push plate 852, causing the two brake pads 855 to rub against the outer wall of the second rotating shaft 830, thereby reducing the relative displacement rate between the first toothed plate 160 and the motor assembly 300. The outer wall of the second rotating shaft 830 is coated with a friction resistance material, which is used to increase the friction between the second rotating shaft 830 and the brake pads 855, ensuring the stability of the motor assembly 300 and the auxiliary drive assembly 800 in cooperating to drive the first toothed plate 160.
