[0024] 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.

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] The technical terms used in the embodiments are explained below:

[0027] The working principle of a buoy wave meter is mainly based on gravity acceleration measurement. It uses an acceleration sensor installed inside the buoy to measure wave parameters by observing the buoy's undulating motion with the waves. Specifically:

[0028] The core working principle of a buoy wave meter is to utilize the buoy's undulating motion with the waves, and to measure the acceleration of seawater particles along the direction of gravity using an accelerometer installed inside the buoy. This acceleration data is then processed through a double integration to obtain the vertical displacement of the buoy, i.e., the vertical motion of the wave. Further analysis of this displacement data allows for the extraction of key parameters such as wave height and period.

[0029] Acceleration measurement: The acceleration sensor inside the buoy measures the acceleration changes of the buoy as it rises and falls with the waves in real time.

[0030] Double integration processing: The measured acceleration data will be processed by double integration to obtain the displacement data of the buoy body in the vertical direction.

[0031] Data analysis: By analyzing the displacement data, parameters such as wave height and period can be extracted. If sensors such as inclinometers are also installed inside the buoy, the direction information of the waves can be further obtained.

[0032] Data transmission: Buoy wave measuring instruments are usually equipped with wireless communication devices, which can transmit the measured data to the shore station receiver and processor in real time.

[0033] Data processing: The shore station receiver further processes and analyzes the received data to obtain more comprehensive wave information, such as wave spectrum and wave energy.

[0034] Surface slope tracking buoys: These buoys calculate the direction and height of waves by measuring the tilt angle of the buoy body. They are typically equipped with sensors such as gyroscopes to determine the vertical reference frame.

[0035] Water particle tracking buoys: These buoys are designed to follow the movement of water particles, and the direction of the buoy's movement is determined by measuring its acceleration in three orthogonal directions. They typically use a triaxial accelerometer as the core sensor, are often spherical in shape, and have better high-frequency response and are less prone to capsizing in steep waves.

[0036] Reference Figures 1 to 4 As shown, the present invention provides a lifting double-layer marine ranching aquaculture device, including a support frame fixed on the coast, a double-layer net cage installed inside the support frame, multiple sliding components installed on the side of the support frame near the double-layer net cage, the double-layer net cage being connected to the multiple sliding components by multiple ropes 26, a square box 11 installed inside the double-layer net cage, the square box 11 being connected to the bottom of the double-layer net cage by multiple square box ropes 25, an airbag 12 installed inside the square box 11, the airbag 12 being connected to an air supply component, multiple through holes 18 for seawater to enter and exit the outer wall of the square box 11, the double-layer net cage being used to cultivate attached organisms, a counterweight 20 installed at the bottom of the double-layer net cage, and a net cover installed on the top of the double-layer net cage.

[0037] In this embodiment, the double-layer cage includes an outer cage 16 and an inner cage 15, with the inner cage 15 constrained within the outer cage 16 by cage pull ropes 24.

[0038] When the sea breeze arrives, the airbag 12 is deflated. As the volume of the airbag 12 gradually decreases, seawater flows back into the box 11 through the through hole 18. At this time, the buoyancy of the box 11 gradually decreases. Under the action of the counterweight 20, the double-layer net cage gradually sinks into the sea, thereby reducing the impact of the waves. After the sea breeze passes, the airbag 12 is continuously inflated through the air supply component, causing the airbag to expand and expel the seawater from the box 11 until the airbag 12 adheres to the inner wall of the box 11. At this time, the box 11 drives the double-layer net cage to float to the surface of the sea.

[0039] This invention constructs the basic framework of a lifting double-layer marine ranching aquaculture device. The support frame provides stable support, the double-layer net cage increases the aquaculture space, the sliding component and the pull rope 26 work together to realize the lifting of the net cage, the square box 11 and the internal airbag 12 work together with the air supply component to adjust the overall buoyancy of the device to control the lifting of the double-layer net cage, the counterweight 20 helps stabilize the position of the device, and the net cover prevents the aquaculture organisms from escaping.

[0040] Furthermore, side windows are provided on the opposite side walls of the box 11. Two hinge seats 23 are fixedly connected to the frame of the side window, and a side window 22 is hinged between the two hinge seats 23. Multiple through holes 18 are opened on the side window 22.

[0041] In this embodiment, a limiting block is provided at the end of the side window 22 away from the hinge seat 23. With this structural arrangement, when the airbag 12 deflates and its volume shrinks, the airbag 12 and the side window 22 lose their force, and seawater rushes through the side window 22 and into the square box 11. Under the pressure of the seawater, the airbag 12 deflates faster, and at the same time, the double-layer net box sinks faster.

[0042] Furthermore, the air supply component includes an air pump 17, the air outlet of which is connected to the airbag 12 via an air inlet pipe; the air vent at the bottom of the airbag 12 is connected to a venting component via an exhaust pipe, and an electromagnetic valve is installed on the exhaust pipe.

[0043] The air pump 17 can inflate the airbag 12, increasing its volume and buoyancy, thus raising the device. The deflation component and the solenoid valve work together to control the deflation of the airbag 12, reducing buoyancy and lowering the double net boxes, thereby achieving precise control over the raising and lowering of the device.

[0044] Furthermore, the venting assembly includes an air storage plate 14 connected to the top of the box 11. The air storage chamber inside the air storage plate 14 is connected to the exhaust pipe. Multiple jet nozzles 13 are equally spaced on the side of the air storage plate 14 away from the box 11. All jet nozzles 13 are connected to the air storage chamber, and a one-way valve is provided on the jet nozzle 13.

[0045] The design of the air storage plate 14 and multiple jet nozzles 13 allows the gas discharged from the airbag 12 to be evenly dispersed and ejected. During the jetting process, the gas impacts the seawater, thereby providing a counter-thrust to the square box 11, which helps the double-layer net box to sink faster. The one-way valve can prevent seawater from flowing back into the airbag 12, ensuring the safety and stability of the deflation process.

[0046] Furthermore, the support frame includes multiple columns 3, with mounting bases 2 vertically connected to the bottom of each column 3. The mounting bases 2 are connected to the seabed foundation 1 via anchors, and adjacent columns 3 are connected by crossbars to form a frame for constraining the double-layer cages.

[0047] The column 3 and the mounting base 2 are fixed to the seabed foundation 1 by anchors, providing a stable foundation support for the entire device; the crossbar connects the adjacent columns 3 to form a frame, which can effectively constrain the position of the double-layer cage and ensure the stability of the double-layer cage.

[0048] Furthermore, the sliding assembly includes brackets 4 connected to both ends of the column 3, a sliding rod 5 fixedly connected between the two brackets 4, and multiple sliding parts slidably mounted on the sliding rod 5. The sliding parts are connected to the double-layer cage via a pull rope 26.

[0049] The bracket 4 fixes the slide bar 5, and the slide assembly slides on the slide bar 5. It is connected to the double-layer net cage through the pull rope 26, so that the double-layer net cage can slide smoothly along the slide bar 5 in the vertical direction to realize the lifting function. The structure is simple and reliable.

[0050] Furthermore, the sliding assembly includes a sliding sleeve 6 that is slidably sleeved on the sliding rod 5, and a plurality of balls 21 are provided between the sliding sleeve 6 and the sliding rod 5, with the plurality of balls 21 embedded in the sliding sleeve 6.

[0051] The ball bearing 21 is set between the sliding sleeve 6 and the sliding rod 5, which transforms sliding friction into rolling friction, greatly reducing the friction force when the sliding sleeve 6 slides on the sliding rod 5, making the lifting and lowering of the double-layer cage easier and more flexible, and reducing energy loss.

[0052] Furthermore, a support plate 8 is connected between the two columns 3, and a solar panel 10 is installed on the support plate 8. The solar panel 10 is electrically connected to a storage battery, and the gas supply component is electrically connected to the storage battery.

[0053] The solar panel 10 can convert solar energy into electrical energy and store it in a battery to provide power to the gas supply components, achieving energy self-sufficiency, reducing dependence on external power sources, and is energy-saving, environmentally friendly, and suitable for marine environments.

[0054] Furthermore, an aeration plate 19 is installed on the inner bottom mesh surface of the double-layer cage, and the aeration plate 19 is connected to an aeration pump 9.

[0055] The aeration pump 9 aerates the double-layer net cage through the aeration plate 19, increasing the dissolved oxygen content in the water, providing a good living environment for the aquatic attached organisms, promoting their growth and metabolism, and improving the yield and quality of aquaculture.

[0056] Furthermore, it also includes a wave meter 7, which is electrically connected to a controller, and the gas supply assembly is electrically connected to the controller.

[0057] In this embodiment, the wave meter 7 is selected as a buoy-type wave meter 7.

[0058] The wave meter 7 can monitor ocean wave conditions in real time and transmit the data to the controller. The controller controls the operation of the air supply component based on the wave data and adjusts the lifting and lowering of the device in time when the waves are large to avoid excessive impact on the device and ensure the safety of the aquaculture device and aquaculture organisms.

[0059] The lifting double-layer marine ranching device provided by the present invention works as follows: The device senses changes in the marine environment, mainly the wave conditions, and uses the air supply component to inflate or deflate the airbag 12 to change the buoyancy of the square box 11, thereby controlling the lifting and lowering of the double-layer net cage to adapt to different marine environments and avoid damage caused by wave impact.

[0060] When the marine environment is relatively stable, without significant sea winds or waves, the device operates under normal aquaculture conditions. At this time, the air pump 17 in the aeration assembly has inflated a certain amount of gas into the air bladder 12. The air bladder 12 expands and adheres to the inner wall of the square box 11. The square box 11 has significant buoyancy. Under the combined action of buoyancy and the counterweight 20, the double-layer net cage is positioned at a suitable aquaculture depth. The outer net cage 16 and the inner net cage 15 of the double-layer net cage provide a stable aquaculture space for the attached organisms, and the net cover prevents the aquaculture organisms from escaping. When oxygen supply is needed, continuous aeration can be provided into the double-layer net cage through the aeration pump 9 and aeration plate 19 to increase the dissolved oxygen content in the water, providing a favorable living environment for the aquaculture organisms and promoting their growth and metabolism.

[0061] The wave meter 7 monitors ocean wave conditions in real time. When it detects an approaching sea breeze and increasing wave size, it transmits wave data to a controller electrically connected to it. Based on the received wave data, the controller issues a command to open the solenoid valve on the exhaust pipe of the air supply assembly. Gas from the airbag 12 enters the air storage chamber of the air storage plate 14 in the air release assembly through the exhaust pipe, and is then evenly dispersed and ejected from multiple jet nozzles 13. During the ejection process, the gas impacts the seawater, providing a counter-thrust force to the air storage plate 14 and the square box 11, which helps the double-layer net cage sink faster. As the volume of the airbag 12 gradually decreases, its force on the side window 22 decreases. Under the pressure of the seawater, the side window 22 rotates and opens around the hinge seat 23, allowing seawater to rush into the square box 11 through the side window 22, further accelerating the sinking of the double-layer net cage.

[0062] As the amount of seawater in the box 11 increases, its buoyancy gradually decreases. Under the gravity of the counterweight 20, the double-layer net cage gradually sinks into the sea along the slide bar 5 until it reaches a suitable depth. At this time, the aeration pump 9 can be turned on to continuously aerate the double-layer net cage, reducing the impact of sea waves on the cultured organisms.

[0063] The wave meter 7 continuously monitors the wave conditions. When it detects that the sea breeze has subsided and the waves have decreased, it transmits the new wave data to the controller. Based on the new wave data, the controller determines the position where the device needs to be raised and issues a command to start the air pump 17. The air pump 17 continuously inflates the airbag 12 through the air inlet pipe. The airbag 12 gradually expands, expelling the seawater in the box 11 through the through hole 18 and the side window 22. As the volume of the airbag 12 increases, the side window 22 is pushed closed by the airbag 12, and the buoyancy of the box 11 gradually increases. When the airbag 12 is pressed against the inner wall of the box 11 again, the buoyancy of the box 11 reaches its maximum. Under the action of buoyancy, the double-layer net cage gradually floats out of the sea along the slide bar 5, returning to the normal aquaculture depth and continuing to provide a suitable living environment for the cultured organisms.

[0064] Throughout the operation, the solar panel 10 installed on the tray 8 converts solar energy into electrical energy, which is then stored in a battery connected to it. The battery provides power to equipment such as the air pump 17, solenoid valve, wave meter 7, controller, and aeration pump 9, achieving energy self-sufficiency, reducing dependence on external power sources, and is energy-saving, environmentally friendly, and suitable for marine environments.
