DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0019] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0020] The technical terms in the embodiments will be explained as follows: The specific working principle of the buoy wave gauge is mainly based on gravity acceleration measurement. The wave parameters are measured by using the fluctuation movement of the buoy body with the wave through the acceleration sensor installed in the buoy body. Specifically as follows: The core working principle of the buoy wave gauge is to measure the acceleration of seawater particles along the gravity direction through the acceleration sensor installed in the buoy body by using the fluctuation movement of the buoy body with the wave. After the acceleration data is processed by twice integration, the displacement of the buoy body in the vertical direction, i.e. the vertical movement of the wave, can be obtained. By analyzing these displacement data, the key parameters such as wave height and period of the wave can be extracted.

[0021] Acceleration measurement: the acceleration sensor in the buoy body measures the acceleration change of the buoy body when it fluctuates with the wave in real time.

[0022] ​Second-order integration: The measured acceleration data is subjected to second-order integration to obtain the displacement data of the buoy body in the vertical direction.

[0023] Data analysis: By analyzing the displacement data, parameters such as wave height and period can be extracted. If inclinometers or other sensors are installed in the buoy, further directional information of the wave can be obtained.

[0024] Data transmission: The wave buoy is usually equipped with wireless communication equipment to transmit the measured data to the shore station receiver in real time.

[0025] 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.

[0026] Surface slope tracking buoy: This type of buoy calculates the direction and height of the wave by measuring the inclination angle of the buoy body. They are usually equipped with gyroscopes and other sensors to determine the vertical reference system.

[0027] Water quality point tracking buoy: This type of buoy is designed to move with the water quality point, and determines the direction of buoy movement by measuring its acceleration in three orthogonal directions. They usually use three-axis accelerometers as core sensors, and are often spherical in shape, with better high-frequency response and less prone to overturning in steep wave conditions.

[0028] Referring to Figures 1 to 4 The present application provides a lifting type double-layer marine ranching device, which comprises a support frame fixed on the coast, a double-layer net cage arranged in the support frame, a plurality of sliding assemblies arranged on one side of the support frame close to the double-layer net cage, a plurality of sliding assemblies corresponding to the double-layer net cage connected through a plurality of pull ropes 26, a square box 11 arranged in the double-layer net cage, and a plurality of square box pull ropes 25 connecting the square box 11 with the bottom of the double-layer net cage; a gas bag 12 is arranged in the square box 11, and the gas bag 12 is connected with a gas supply assembly; a plurality of through holes 18 for the inlet and outlet of seawater are arranged on the outer wall of the square box 11, the double-layer net cage is used for breeding sessile organisms, a counterweight 20 is arranged at the bottom of the double-layer net cage, and a net cover is arranged on the top of the double-layer net cage.

[0029] In the embodiment, the double-layer net cage comprises an outer net cage 16 and an inner net cage 15, and the inner net cage 15 is constrained in the outer net cage 16 through a net cage pull rope 24.

[0030] When the sea wind comes, the air bag 12 is exhausted, and as the volume of the air bag 12 gradually decreases, the seawater flows into the square box 11 through the through hole 18, at this time, the buoyancy of the square box 11 gradually decreases, and under the action of the counterweight 20, the double-layer net cage gradually sinks into the sea, thereby reducing the impact of the sea waves; after the sea wind, the air bag 12 is inflated by the air supply assembly, the seawater in the square box 11 is discharged, and the air bag 12 is inflated until the air bag 12 is attached to the inner wall of the square box 11, at this time, the square box 11 drives the double-layer net cage to float out of the sea.

[0031] The present application constructs the basic framework of the lifting type double-layer marine ranching device, provides stable support through the support frame, increases the breeding space through the double-layer net cage, realizes the lifting of the net cage through the cooperation of the sliding assembly and the pull rope 26, adjusts the overall buoyancy of the device through the cooperation of the square box 11 and the internal air bag 12 and the air supply assembly, assists the stable position of the device through the counterweight 20, and prevents the escape of the breeding organisms through the net cover.

[0032] Further, side windows are formed in the opposite side walls of the square box 11, two hinge seats 23 are fixedly connected to the frames of the side windows, and a side window 22 is hinged between the two hinge seats 23.

[0033] In the embodiment, a limiting block is arranged at one end of the side window 22 away from the hinge seat 23, and such a structure arrangement loses the force between the air bag 12 and the side window 22 when the air bag 12 is deflated and the volume is reduced, the seawater rushes into the square box 11 by breaking the side window 22, and the deflation of the air bag 12 is accelerated under the confining pressure of the seawater, and the sinking of the double-layer net cage is also accelerated.

[0034] Further, the air supply assembly comprises an inflation pump 17, the gas outlet of the inflation pump 17 is communicated with the air bag 12 through an air inlet pipe, and the bottom deflation port of the air bag 12 is connected with a deflation assembly through an air outlet pipe, and an electromagnetic valve is arranged on the air outlet pipe.

[0035] The inflation pump 17 can inflate the air bag 12, increase the volume and buoyancy of the air bag 12, and make the device rise; the deflation assembly and the electromagnetic valve cooperate to control the deflation of the air bag 12, reduce the buoyancy, and make the double net cage descend, thereby realizing the accurate control of the lifting of the device.

[0036] Further, the deflation assembly comprises a gas storage plate 14 connected to the top of the square box 11, a gas storage cavity in the gas storage plate 14 is communicated with the air outlet pipe, a plurality of jet heads 13 are arranged at equal intervals on the side of the gas storage plate 14 away from the square box 11, the plurality of jet heads 13 are communicated with the gas storage cavity, and a one-way valve is arranged on the jet head 13.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] In this embodiment, the wave meter 7 is selected as a buoy-type wave meter 7.

[0050] 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.

[0051] 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. 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.
