Description

Technical Field

[0001] This invention relates to the field of water quality monitoring technology, specifically a floating monitoring platform for monitoring the water quality of marine aquaculture. Background Technology

[0002] A floating monitoring platform for marine aquaculture water quality monitoring is a type of platform that uses buoy technology to monitor the water quality of marine aquaculture. The floating monitoring platform can achieve real-time monitoring of the water quality in aquaculture areas. It is deployed in marine aquaculture areas for monitoring, and the monitoring platform integrates sensors, data acquisition and transmission systems to achieve in-situ, real-time, multi-parameter, and long-term continuous monitoring of water quality. The buoy structure of the monitoring platform is usually made of materials that are resistant to seawater corrosion and prevent biofouling, providing buoyancy and supporting various equipment. Current aquaculture monitoring floating platforms mostly use a single buoy or a simple counterweight structure to provide buoyancy and stability. When encountering large winds, waves, or strong currents, the floating platform is prone to violent swaying under the impact of waves, resulting in distorted or even damaged measurement data from the onboard monitoring equipment. Furthermore, the floating platform is prone to capsizing under extreme sea conditions, causing data interruption and equipment loss. In addition, current floating platforms lack active buffering mechanisms, causing the main body of the floating platform to passively bear the impact of waves, making it impossible to dissipate energy and maintain stability at the moment of impact. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a floating monitoring platform for monitoring water quality in marine aquaculture. It solves the problems of current aquaculture monitoring platforms, which often use a single buoy or simple counterweight structure to provide buoyancy and stability. These platforms are prone to violent swaying under wave impact when encountering large waves or strong currents, leading to distorted or even damaged data from the onboard monitoring equipment. Furthermore, in extreme sea conditions, the platforms are prone to capsizing, causing data interruption and equipment loss. Additionally, current platforms lack active buffering mechanisms, resulting in the platform body passively bearing the wave impact without dissipating energy or maintaining stability during the impact.

The yield strength of the magnetorheological fluid is controlled by adjusting the current. The current control of the electromagnetic coil is realized by the controller. The controller is connected to the electromagnetic coil 16 to adjust the current according to the wind force.

[0007] As a preferred technical solution of the floating monitoring platform for monitoring the water quality of marine aquaculture according to the present invention, the external rotating drum, the internal sleeve and the damping cylinder are integrally connected, and the top and bottom of the external rotating drum and the damping cylinder are sealed to the central rod through a sealing bushing. When the damping cylinder drives the moving blade to rotate, the edge of the moving blade and the end of the fixed blade come into contact.

[0008] As a preferred technical solution of the floating monitoring platform for monitoring the water quality of marine aquaculture according to the present invention, an outer box is fitted and installed on the outer side of the equipment box, a U-shaped water flow channel is provided inside the outer box, and drainage plates are evenly and equidistantly arranged in the U-shaped water flow channels on both sides of the inner side of the outer box. A heat transfer inner plate is provided on the inner side of the outer box, and metal plates are evenly arranged at the contact position between the inner wall of the heat transfer inner plate and the outer wall of the equipment box. A water inlet pipe is connected to the top of one side of the external housing, and a water outlet pipe is connected to the bottom of the other side of the external housing. A water pump is installed on the water inlet pipe, and filter heads are installed at the bottom of both the water inlet pipe and the water outlet pipe.

[0009] As a preferred technical solution of the floating monitoring platform for monitoring the water quality of marine aquaculture according to the present invention, the external box is fitted on the outside of the equipment box, the outer wall of the equipment box is in close contact with the heat transfer inner plate and the metal plate, and the inner wall of the equipment box is also provided with a heat-conducting plate, and the signal input terminal of the water pump is connected to the controller.

[0010] As a preferred technical solution of the floating monitoring platform for monitoring the water quality of marine aquaculture according to the present invention, the cross-section of the external box and the U-shaped flow channel is U-shaped, and the drainage plate divides the two sides of the U-shaped flow channel to form multiple uniform drainage channels. The outlet end of the water inlet pipe is connected to the top of the loop-shaped water trough, and the inlet end of the outlet pipe is connected to the bottom of the loop-shaped water trough. The bottom of the loop-shaped water trough is set as a slope, and the external position of the inlet end near the outlet pipe is set as a low position. The filter heads at the bottom of the inlet and outlet pipes extend below the liquid surface, and filter screens are installed inside the filter heads.

[0011] As a preferred technical solution of the floating monitoring platform for monitoring the water quality of marine aquaculture according to the present invention, the two sides of the buoy body are symmetrically connected with connecting rings, and the inside of the connecting rings is limited and bound with a traction cable, one end of which is connected to the side of the traction box. An electric slide rail is installed on one side of the traction box. The traction box slides along the electric slide rail guided by a slider on its side. A protective box is installed on one side of the traction box, and a motor is installed inside the protective box. A guide tube is connected to the side of the traction box corresponding to the entry and exit position of the traction cable. A rotating shaft is installed in the middle of the inner side of the traction box. One end of the rotating shaft is connected to the motor, and a winding disc is installed on the outer side of the rotating shaft at the position inside the traction box.

[0012] As a preferred technical solution of the floating monitoring platform for monitoring the water quality of marine aquaculture according to the present invention, a traction box and an electric slide rail are symmetrically installed on both sides of the buoy body. The electric slide rail is installed on the marine aquaculture enclosure, and the electric slide rail drives the traction box and the buoy body to move vertically, while the traction box drives the buoy body to move horizontally.

[0013] As a preferred technical solution of the floating monitoring platform for monitoring the water quality of marine aquaculture according to the present invention, the traction cable is connected to the inside of the traction box through a conduit, and the end of the traction cable is fixedly installed on the winding reel. The motor drives the winding reel to rotate through the rotating shaft, and the two winding reels on both sides of the buoy body realize the winding and unwinding operations simultaneously.

[0014] Compared with the prior art, the present invention provides a floating monitoring platform for monitoring the water quality of marine aquaculture, which has the following beneficial effects: 1. By uniformly setting floats along the edges of the buoy body, the fluid pressure can drive the drive blades to deflect when resisting wind and waves. The pressure relief and flow channels set along the edges of the floats can achieve initial pressure distribution and reduce local impact loads. When the drive blades rotate, they simultaneously drive the external rotating cylinder, the internal sleeve, and the damping cylinder to rotate. The sealed bushing ensures the airtightness of the rotating connection and prevents seawater leakage. When the damping cylinder rotates, it drives the moving blade plate to rotate actively in the filling cavity. Together with the fixed blade plate on the edge of the central rod and the damping shear holes evenly distributed inside the moving blade plate, it achieves a combined squeezing and shearing effect on the damping fluid in the filling cavity. This efficiently consumes and absorbs the impact kinetic energy of the waves acting on the buoy body, allowing the buoy body to maintain stable attitude under complex sea conditions and have higher wind and wave resistance. By making the damping fluid bear both squeezing and shearing effects at the same time, compared with single shear damping, the energy consumption efficiency is improved, and the damping force adapts to the rotation speed, exhibiting good nonlinear buffering characteristics. The wind speed and direction instrument detects the sea surface wind force in real time. When the wind force is strong, the controller adjusts the input current of the electromagnetic coil. By adjusting the current, the magnetic field strength is changed, thereby actively adjusting the yield strength of the magnetorheological fluid and realizing the active adjustment of energy dissipation capacity. This adjustment mechanism can dynamically adjust the damping force according to the on-site wind and wave conditions, so that the apparent viscosity of the damping fluid in the filling cavity changes adaptively with the environment. This provides greater damping energy dissipation when the wind and waves are severe, and avoids over-damping affecting the normal response of the buoy when the wind and waves are small. It balances stability and sensitivity, and can cover different scenarios without changing the damping medium, improving the stability and environmental adaptability of the buoy. The magnetorheological fluid compression-shear composite energy dissipation mechanism inside the buoy converts wave impact kinetic energy into damping heat energy and actively adjusts the yield strength to maintain the buoy's attitude stability in complex sea conditions. Furthermore, due to the staggered arrangement of moving and fixed blades and the presence of damping shear holes on the moving blades, the magnetorheological fluid is subjected to both compression and shearing effects simultaneously. Compared to a single shear mode, the energy dissipation efficiency per unit volume is improved, and the damping force increases non-linearly with the rotational speed.

[0015] 2. By installing a U-shaped external enclosure around the equipment box, the cooling water is conveniently transported to the U-shaped water trough using a water supply and drainage loop consisting of an inlet pipe, an outlet pipe, and a water pump. The filter head filters and intercepts impurities in the incoming water to prevent clogging. At the same time, the drainage plates evenly arranged on both sides of the U-shaped water trough can distribute the cooling water delivered to the top of the U-shaped water trough downwards along the side walls of the equipment box, so that the cooling water forms a uniform thin film flow, which increases the heat exchange area, improves the heat dissipation uniformity, and avoids local hot spots. In conjunction with the heat transfer inner plate and metal plate, the heat generated by the electrical equipment inside the equipment box during operation is absorbed and transferred, thereby reducing the internal operating temperature of the equipment box. Based on the continuous operation of the water pump, circulating heat dissipation can be achieved, making full use of the natural conditions on site. By taking advantage of the characteristic that the water temperature is lower than the equipment operating temperature, passive heat dissipation is achieved. Seawater is used as the cooling medium, eliminating the need for additional refrigeration equipment. It is suitable for unattended, long-term operation monitoring buoys, ensuring the stable operation of the equipment box and avoiding adverse effects of high temperature on monitoring operations.

[0016] 3. By connecting the rings on both sides of the buoy body and combining them with the traction cable, it is convenient to connect the buoy body to the external traction mechanism. The traction cables on both sides of the buoy body are connected to the corresponding traction boxes. The motor drives the winding disc to rotate, causing the traction cable to be wound up and down, which in turn moves the buoy body. The guide tube guides the traction cable to prevent it from getting tangled, ensuring that the buoy body slides stably. The buoy body's monitoring position is adjusted by sliding, expanding its monitoring range from single-point monitoring to linear monitoring along the line. The movement of the buoy body by winding up the traction cable facilitates the buoy body's recovery and reduces maintenance difficulty. Meanwhile, by installing horizontally opposite electric sliding rails on the marine aquaculture enclosure, the sliding rails drive the slider and traction box to slide, which in turn drives the buoy to slide. This expands the monitoring range of the buoy from linear monitoring to area monitoring. Through multi-level conversion from point to line to area, the buoy can be adjusted linearly along a single axis and area-wise along the enclosure. This ensures that a single buoy can cover multiple monitoring areas of a single aquaculture enclosure, achieving precise monitoring at fixed points and in fixed areas. This eliminates the need for repeated deployment of buoys, significantly reducing equipment investment and maintenance costs.

[0017] In summary, the buoy achieves a dual stabilization mechanism of internal energy dissipation and external constraint while maintaining stability against wind and waves. On the one hand, relying on the multi-stage damping energy dissipation structure and magnetorheological damping adaptive adjustment inside the buoy, it actively absorbs and dissipates the kinetic energy of wave impact from the attitude dimension, enabling the buoy to remain stable under normal sea conditions and possess a progressive buffering capability to cope with medium and large waves. On the other hand, relying on the external constraint mechanism composed of towing cables, towing boxes, and electric sliding rails, it restricts the horizontal displacement and drift of the buoy from the position dimension, further suppressing the risk of violent swaying and drifting of the buoy under extreme sea conditions. In this way, the buoy can maintain attitude and position stability under light, medium, large, and even extreme sea conditions. Attached Figure Description

A float 8 is evenly embedded in the edge of the buoy body 1 at equal angles along the circumference. A pressure relief flow groove 9 is evenly opened on the side of the float 8. A bearing seat 10 is fixedly installed at the top and bottom center of the float 8. A central rod 13 is fixedly connected to the inner side of the bearing seat 10. An external rotating cylinder 11 is rotatably connected to the inner center of the float 8. A drive blade 12 is evenly arranged on the edge of the external rotating cylinder 11 along the circumference.

[0033] Photovoltaic panels 3 are symmetrically connected to the two inclined sides of the mounting frame 2. A counterweight frame 6 is installed at the bottom edge of the buoy body 1, and a protective sleeve 7 is installed at the bottom of the buoy body 1 inside the counterweight frame 6. The buoy body 1 has an integrated equipment compartment, in which temperature, salinity, and depth sensors and water quality monitoring instruments are installed.

When the electromagnetic coil 16 is at a current of 1A, the magnetorheological fluid can provide an additional 30% damping force, realizing active adjustment of energy dissipation capacity. The electromagnetic coil 16 is configured to be connected to the controller to adjust the damping force of the magnetorheological fluid, so that the apparent viscosity of the magnetorheological fluid in the filling cavity 18 changes adaptively with the intensity of the applied magnetic field. It provides high damping energy dissipation when the wind and waves are strong, and maintains low damping response sensitivity when the wind and waves are small.

[0034] An outer casing 22 is fitted onto the outer side of the equipment box 4. A U-shaped water channel 23 is provided inside the outer casing 22. Drainage plates 24 are evenly and equidistantly arranged in the U-shaped water channel 23 on both sides of the outer casing 22. The cross-section of the outer casing 22 and the U-shaped water channel 23 is U-shaped. The drainage plates 24 divide the two sides of the U-shaped water channel 23 to form multiple uniform drainage channels. A heat transfer inner plate 25 is provided on the inner side of the outer casing 22. Metal plates 26 are evenly arranged at the contact position between the inner wall of the heat transfer inner plate 25 and the outer wall of the equipment box 4.

The bottom of the U-shaped water trough 23 is set as a slope, and the external end near the inlet end of the water outlet pipe 28 is set at a lower position to achieve water flow guidance. A water pump 29 is installed on the water inlet pipe 27. The external housing 22 is fitted onto the outside of the equipment box 4. The outer wall of the equipment box 4 is in close contact with the heat transfer inner plate 25 and the metal plate 26, and the inner wall of the equipment box 4 is also equipped with a heat-conducting plate. The signal input terminal of the water pump 29 is connected to the controller. Filter heads 30 are installed at the bottom of the water inlet pipe 27 and the water outlet pipe 28. The filter heads 30 at the bottom of the water inlet pipe 27 and the water outlet pipe 28 extend below the liquid surface, and a filter screen is installed inside the filter head 30. The depth of the filter head 30 below the liquid surface is determined according to the sea surface water temperature, so that the water temperature entering the filter head 30 is lower.

[0035] The two sides of the buoy body 1 are symmetrically connected with connecting rings 31, and the inside of the connecting rings 31 is bound with a traction cable 32. One end of the traction cable 32 is connected to the side of the traction box 33. An electric slide rail 34 is installed on one side of the towing box 33. The towing box 33 and the electric slide rail 34 are symmetrically installed on both sides of the buoy body 1. The electric slide rail 34 is installed on the marine aquaculture enclosure and drives the towing box 33 and the buoy body 1 to move vertically. The towing box 33 drives the buoy body 1 to move horizontally. The towing box 33 slides along the electric slide rail 34 guided by the slider 35 on its side. A protective box 36 is installed on one side of the towing box 33. A motor 39 is installed inside the protective box 36. A guide tube 37 is connected to the side of the traction box 33 corresponding to the entry and exit position of the traction cable 32. A rotating shaft 38 is installed in the middle of the inner side of the traction box 33. One end of the rotating shaft 38 is connected to the motor 39, and a winding disc 40 is installed on the outer side of the rotating shaft 38 inside the traction box 33. The traction cable 32 is connected to the inside of the traction box 33 through the guide tube 37, and the end of the traction cable 32 is fixedly installed on the winding disc 40. The motor 39 drives the winding disc 40 to rotate through the rotating shaft 38. The two winding discs 40 on both sides of the buoy body 1 realize the winding and unwinding operations simultaneously.

[0036] The working principle and usage process of this invention are as follows: First, electric slide rails 34 are installed horizontally opposite each other on the seawater aquaculture enclosure, so that the traction box 33 is slidably connected to the electric slide rails 34 through the drive slider 35. Then, the buoy body 1 is connected by the connecting rings 31 on both sides of the buoy body 1 and the traction cable 32. The traction cables 32 on both sides of the buoy body 1 are respectively connected to the traction box 33 on the corresponding side, so that the buoy body 1 is placed on the sea surface. The photovoltaic panel 3 provides electric energy, the anemometer 5 monitors the wind force, and the counterweight frame 6 provides counterweight and protection at the same time. The protective sleeve 7 is used to protect the water quality probe. The monitoring electrical appliances in the equipment box 4 receive the water quality monitoring data and transmit it to the terminal. During the operation of equipment box 4, when the internal temperature sensor detects that the temperature is too high, the controller sends a command to start water pump 29. Using the water supply and drainage pipeline composed of inlet pipe 27 and outlet pipe 28, cooling water is transported to the loop-shaped water channel 23 inside the external box 22. The filter head 30 filters the incoming water to avoid clogging. After the water flows into the loop-shaped water channel 23, the water-draining plates 24 evenly arranged on both sides of the loop-shaped water channel 23 distribute the cooling water delivered to the top of the loop-shaped water channel 23 evenly along the two side walls of equipment box 4. With the help of the heat transfer inner plate 25 and the metal plate 26, the heat generated by the electrical equipment inside equipment box 4 is absorbed and transferred, reducing the internal operating temperature of equipment box 4. Based on the circulation operation of water pump 29, heat dissipation is easily achieved, and stable operation of equipment box 4 is realized. When the wind picks up at sea, the wind speed and direction instrument 5 detects the wind force at sea. When the buoy body 1 resists the wind and waves, the evenly arranged floats 8 on its side can drive the drive blade 12 to deflect based on the fluid pressure. The pressure relief flow groove 9 on the side of the float 8 is used to achieve initial pressure distribution. When the drive blade 12 rotates, it synchronously drives the external rotating cylinder 11, the internal sleeve 15 and the damping cylinder 17 to rotate synchronously. The sealing bushing 14 ensures the airtightness of its rotating connection position and avoids leakage. When the damping cylinder 17 rotates, it synchronously drives the moving blade 19 to rotate actively in the filling cavity 18. In conjunction with the fixed blade 21 on the side of the central rod 13 and the damping shear hole 20 inside the moving blade 19, the damping fluid in the filling cavity 18 is compressed and sheared, thereby consuming and absorbing the impact kinetic energy of the wave flow on the buoy body 1, keeping the buoy body 1 stable. In addition, when the anemometer 5 detects that the wind force is large, the controller controls the input current of the electromagnetic coil 16. By adjusting the current, the yield strength of the magnetorheological fluid is controlled, thereby realizing the active adjustment of the energy consumption capacity. Specifically, under the currents of 0A, 0.5A, 1.0A, and 1.5A, the magnetorheological fluid can provide an additional 0%, 15%, 30%, and 45% damping force, respectively. Based on the wind force monitoring results, the damping force is actively and adaptively adjusted so that the viscosity of the damping fluid in the filling cavity 18 can adapt to the changes in the field environment, thereby improving the stability effect. When it is necessary to adjust the monitoring range of buoy 1, the motor 39 drives the winding disc 40 to rotate, causing the traction cable 32 to slide the buoy 1. The guide tube 37 guides the traction cable 32 to make the buoy 1 slide stably. The monitoring position of buoy 1 is adjusted by sliding, so that the monitoring range is changed from single-point monitoring to monitoring along a straight line. The movement of buoy 1 by traction cable 32 also makes it easier to collect buoy 1 and reduces its maintenance difficulty. Next, the electric sliding rail 34 on the marine aquaculture enclosure drives the slider 35 and the traction box 33 to slide linearly, so that the traction box 33 synchronously drives the buoy body 1 to slide, so that the monitoring range of the buoy body 1 can be converted on the basis of linear monitoring. In this way, through the multi-level conversion of point, line and surface, a single buoy body 1 can comprehensively monitor the aquaculture area within a single aquaculture enclosure without repeated investment, thus reducing costs.
