Description

Technical Field

[0001] This invention belongs to the field of aquaculture cage technology, and specifically relates to a pomfret aquaculture cage with red tide early warning function. Background Technology

[0002] In marine aquaculture, pomfret has high economic value and market demand. It is primarily cultured in net cages placed in waters with good quality. Most commercially available pomfret farming net cages are box-shaped or cylindrical structures with an open top, facilitating feeding, observation, inspection, and management by aquaculture operators. Due to the high water quality requirements of pomfret, red tides are the most detrimental factor in aquaculture. When a red tide occurs, plankton proliferates in large numbers at the sea surface, greatly increasing seawater turbidity and drastically reducing oxygen levels. Pomfret rely on dissolved oxygen for respiration; reduced oxygen levels severely impair their respiration, leading to physiological damage, slow growth, and even mass mortality, causing significant losses to aquaculture farmers. Red tides occur from various sources and through different pathways, mainly categorized as either locally occurring or drifting from other locations.

[0003] Given the severe damage that red tides pose to pomfret farming, existing aquaculture cages have significant shortcomings. Current cages only possess basic aquaculture functions and cannot provide early warning of red tide occurrences. When a red tide suddenly occurs or drifts from other areas to the aquaculture area, farmers are often unaware in time, exposing the pomfret inside to a polluted water environment. Furthermore, existing cages lack effective isolation and treatment devices in their structure. When the cages are within a red tide zone or need to pass through a red tide-affected area, they cannot effectively isolate the aquaculture water inside the cages from the polluted seawater outside, nor can they treat the already contaminated water inside the cages, easily leading to the pomfret being harmed by red tides. Summary of the Invention

[0004] This invention provides a pomfret aquaculture cage with red tide early warning function. This new type of cage can not only predict the occurrence and arrival of red tides and provide early warning information to aquaculture personnel in advance, but also isolate the aquaculture water inside the cage from the outside when the cage is within the red tide range or needs to pass through the red tide occurrence area, and treat the aquaculture water inside the cage to reduce the impact of red tide on pomfret.

[0005] The technical solution adopted in this invention:

[0006] A pomfret aquaculture cage with red tide early warning function includes a hemispherical cage, a waterproof cloth cover, multiple semi-circular support rods, and a control center. The cage contains a water quality monitoring module and multiple side pipes, each with multiple air holes. Float 1 and Float 2 are connected to opposite sides of the cage's opening via support rod 1 and support rod 2, respectively. Each support rod 1 and support rod 2 is equipped with an electric rotating ring 1 and an electric rotating ring 2. The electric rotating ring 1 is located away from the cage, while the electric rotating ring 2 is located closer to the cage. The support rods are arranged with decreasing radii according to a preset ratio. The longest support rod is connected at both ends to two electric rotating rings 1, and the shortest support rod is connected at both ends to two electric rotating rings 1. On ring two, the two ends of the other support rods are respectively connected to support tube one and support tube two, and the connection point is located between electric rotating ring one and electric rotating ring two. The two support rods with the largest and smallest radii are respectively connected to the two sides of the opening of the waterproof cloth cover. The other support rods are connected to the waterproof cloth cover in order of decreasing radius from the largest to the smallest radius, so that when the support rod with the smallest radius rotates to be parallel to the support rod with the largest radius and the openings of the two are opposite, all the support rods can be distributed in order of decreasing radius and open the waterproof cloth cover to cover the cage. The shortest support rod has an arc-shaped baffle one at its outer end. The outer diameter of the baffle one is not less than the outer diameter of the second largest radius support rod.

[0007] The first float is equipped with a control center and an air pump. The first support pipe is connected to the side pipe. The second float is equipped with a water treatment device, which is connected to the cage through an inlet pipe and an outlet pipe.

[0008] The control center is electrically connected to the water quality monitoring module, electric rotating ring one, electric rotating ring two, air pump and water treatment equipment. The control center can select to send red tide warning signals to the user terminal, control the water-proof cloth cover to unfold the isolation cage, supply oxygen to the cage and treat the aquaculture water in the cage according to the water quality parameters monitored by the water quality monitoring module.

[0009] Furthermore, the baffle is provided with multiple drainage holes.

[0010] Furthermore, a second baffle is provided on the inner side of the support rod with the largest radius, and the second baffle has multiple drainage holes near the middle.

[0011] Furthermore, the inner side of the second baffle is provided with bristles.

[0012] Furthermore, the cage includes an annular tube, a hemispherical baffle net, and a base. The side tubes have an arc-shaped structure. The lower ends of multiple side tubes are connected to the side wall of the base at intervals, and the upper ends of multiple side tubes are connected to the annular tube at intervals. The open end of the baffle net is connected to the outside of the annular tube. The inner wall and bottom of the baffle net are respectively connected to the outside of the side tubes and the base. Support tube one and support tube two are respectively connected to both sides of the annular tube.

[0013] Furthermore, the first support pipe is equipped with an air pipe, which is connected to the annular pipe and the air pump respectively. The water inlet pipe and the water outlet pipe pass through the second support pipe and the annular pipe in sequence and enter the mesh box. The end of the water inlet pipe is equipped with a screen.

[0014] Furthermore, either float one or float two is provided with a tow hook on the side away from the cage.

[0015] Furthermore, both float one and float two are equipped with photovoltaic panels for power supply and energy storage.

[0016] Furthermore, both sides of the float one and float two are connected to pull ropes, the pull ropes are connected to anchor bodies, and the pull ropes are also equipped with counterweights.

[0017] Furthermore, the waterproof fabric cover includes a woven layer, one side of which is provided with a waterproof layer, and both the waterproof layer and the woven layer are provided with a wear-resistant layer on opposite sides.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The water quality monitoring module can monitor the aquaculture water in the net cages in real time and transmit the signal to the control center. When the control center determines that the water quality parameters have reached the red tide warning level, it will send a red tide warning signal to the user terminal via radio through the communication module to remind aquaculture personnel to take precautions in advance.

[0020] 2. When aquaculture workers are unable to move the net cages by boat in time, the seawater around the cages will further deteriorate. When the control center determines that the water quality has affected the growth of the pomfret, it will use poles to cover the net cages with waterproof fabric to isolate them from external seawater and prevent further pollution. Simultaneously, the control center can process and optimize the relevant seawater parameters inside the net cages based on the monitored water quality parameters to reduce the adverse effects of red tides on the pomfret and buy time for subsequent rescue measures by aquaculture workers.

[0021] 3. Generally, when a migrating red tide is predicted and determined, the best course of action is to move the net cages upstream of the red tide area. Therefore, by covering the net cages and allowing them to pass through the red tide while continuously supplying oxygen, the inside of the net cages can be effectively isolated from the polluted seawater outside, ensuring that the pomfret inside the net cages can safely pass through the red tide.

[0029] To better understand the technical content of this invention, specific embodiments are provided below, and the invention will be further described in conjunction with the accompanying drawings.

[0030] See Figures 1 to 6This invention provides a pomfret aquaculture cage with red tide early warning function, including a hemispherical cage, a waterproof cover 25, multiple semi-circular support rods 7, and a control center 4. The cage contains a water quality monitoring module 21 and multiple side pipes 12. The water quality monitoring module 21 monitors parameters such as dissolved oxygen, temperature, turbidity, and pH value of the seawater inside the cage. Changes in these water quality parameters can predict the occurrence of marine red tides. The side pipes 12 have a quarter-circular structure, and multiple air holes are provided on the lower side of the side pipes 12 for supplying oxygen to the underwater air supply. Float 1 and Float 2 15 are fixedly connected to opposite sides of the cage opening via support rod 1 6 and support rod 2 17, respectively. Support rod 1 6 and support rod 2 17 are fixedly connected to the cage. Each support rod 1 6 and support rod 2 17 is equipped with an electric rotating ring 1 9 and an electric rotating ring 2 8. One 9 is located on the side away from the net cage, while the electric rotating ring two 8 is located on the side closer to the net cage. Multiple support rods 7 are arranged with decreasing radius differences according to a preset schedule. The longest support rod 7 is connected at both ends to two electric rotating rings one 9, and the shortest support rod 7 is connected at both ends to two electric rotating rings two 8. Electric rotating rings one 9 and two 8 can respectively drive two support rods 7 on them to rotate around support tube one 6 and support tube two 17. The ends of the other support rods 7 are connected to support tube one 6 and support tube two 17, respectively. The connection points of the other support rods 7 are located between electric rotating rings one 9 and two 8. The two support rods 7 with the largest and smallest radii are connected to the two sides of the opening of the waterproof cloth cover 25, respectively. The other support rods 7 are connected to the waterproof cloth cover 25 at intervals from the largest to the smallest radius support rod 7 (see...). Figure 2 This allows all struts 7 to rotate counterclockwise from largest to smallest radius when the strut 7 with its openings facing each other. (See reference) Figure 2 The distribution of the support rods 7 is such that all the support rods 7 can fully open the waterproof cloth cover 25 and cover the outside of the net cage to isolate the outside seawater from the seawater inside the net cage. The shortest support rod 7 has an arc-shaped baffle 29 fixed at its outer end. The two ends of the baffle 29 extend to the vicinity of the support tube 6 and the support tube 17, respectively. The outer diameter of the baffle 29 is not less than the outer diameter of the second largest radius support rod 7.

[0031] The first float 1 is equipped with a control center 4 and an air pump 2. The first support pipe 6 is connected to the side pipe 12. The second float 15 is equipped with a water treatment device 16. The water treatment device 16 can at least adjust the pH value and turbidity of the aquaculture water and sterilize the aquaculture water. The water treatment device 16 is connected to the net cage through the inlet pipe 18 and the outlet pipe 19.

[0032] The control center 4 is electrically connected to the water quality monitoring module 21, electric rotating ring 1 9, electric rotating ring 2 8, air pump 2 and water treatment equipment 16, and is used to control the operation of related components.

[0033] The working principle of this invention during use is as follows:

[0034] The net cages are placed in suitable marine areas for aquaculture. Using floats 1 and 2 (15), approximately three-quarters of the net cage is submerged in seawater via support pipes 6 and 2 (17). During the aquaculture process, the water quality monitoring module 21 monitors various parameters of the aquaculture water and transmits them to the control center 4. The control center 4 can then make decisions based on the water quality parameters, such as sending a red tide warning signal to the user, controlling the deployment of the waterproof cover 25 to isolate the net cage, supplying oxygen to the net cage, and treating the aquaculture water inside the net cage.

[0035] The following details the various control methods of Control Center 4:

[0036] 1. Sending early warning signals: When the control center 4 determines that the water quality parameters have reached the red tide warning level, the control center 4 sends a red tide warning signal to the user terminal via the communication module in a wireless manner to remind aquaculture personnel to take precautions in advance.

[0037] 2. Isolation of Aquaculture Water: When the control center 4 determines that the water quality is affecting the growth of the pomfret, the control center 4 controls the electric rotating ring 8 to drive the smallest support rod 7 to rotate 180 degrees. Since the support rods 7 are connected to the waterproof cover 25 in order of their size, the smallest support rod 7 will drive the other support rods 7 to rotate counterclockwise through the waterproof cover 25. Except for the largest support rod 7, which is fixed, the rotation angle of the other support rods 7 is in the opposite order of their diameter. That is to say, the larger the support rod 7, the smaller the rotation angle. This allows all the support rods 7 to fully open the waterproof cover 25 and cover the outside of the net cage, so as to isolate the seawater outside from the seawater inside the net cage and avoid further pollution of the seawater inside the net cage by the seawater outside. When it is necessary to retract the waterproof cover 25, the electric rotating ring 2 8 drives the smallest support rod 7 to rotate 180 degrees clockwise. During the rotation, the smallest support rod 7 drives the baffle 1 29 to rotate. The baffle 1 29 pushes the other support rods 7 to retract towards the largest support rod 7, so that the waterproof cover is folded up above the sea surface with a smaller area, avoiding long-term placement in the water and being impacted and corroded by seawater. After being retracted, the smaller folded area also reduces the windproof area on the sea surface.

[0038] 3. Supplying oxygen to the cage: After isolating the cage, when the dissolved air content of the seawater in the cage is too low, the control center 4 controls the air pump 2 to start. The air pump 2 delivers air to the annular pipe 11 through the air pipe 3, and the annular pipe 11 then supplies oxygen to the cage through the air holes on the side pipe 12.

[0039] 4. Treatment of aquaculture water in net cages: On the basis of isolating net cages, when the turbidity and pH value of the seawater in the net cages are found to exceed the standard, the control center 4 controls the water treatment equipment 16 to use the inlet pipe 18 to extract the water from the net cages for treatment and then transport it back to the net cages through the outlet pipe 19 to ensure the quality of aquaculture water.

[0040] Therefore, the net cage of the present invention can not only predict the occurrence and arrival of red tides and provide early warning information for aquaculture personnel, but also isolate the aquaculture water inside the net cage from the outside when the net cage is within the range of a sudden red tide or needs to move to a safe upstream area across the red tide occurrence area, and treat the aquaculture water inside the net cage to reduce the impact of red tide on pomfret.

[0041] Specifically, the baffle 29 is provided with multiple drainage holes 27, which allow seawater to pass through, reducing the water resistance of the baffle 29 when the waterproof cover 25 is retracted.

[0042] Specifically, the inner side of the support rod 7 with the largest radius is equipped with a baffle 26, and the baffle 26 has multiple drainage holes 27 near the middle; when feeding the pomfret in the net cage, the water-proof cloth cover 25 can be unfolded so that the fish feed falling from the net cage during feeding can be collected by the water-proof cloth cover 25. Then, the control center 4 simultaneously controls the electric rotating ring 9 and the electric rotating ring 8 to rotate 90 degrees counterclockwise (see reference). Figure 1 (Direction), during this process, the water inside the waterproof cloth cover 25 will drain through the drain hole 27 on the baffle 26, while the fish feed will be blocked on the baffle 26. Since the drain hole 27 is located in the middle of the baffle 26, the fish feed will be collected in the middle of the baffle 26, which avoids the waste of fish feed during the feeding process and also makes it convenient to collect the fish feed.

[0043] Specifically, the inner side of the baffle 26 is equipped with bristles 28, which are composed of multiple plastic filaments with a diameter of 1-3mm. Since the net cage is submerged in seawater for a long time, aquatic organisms such as barnacles will inevitably grow. Therefore, when the waterproof cover 25 is unfolded or fully retracted, the control center 4 controls the electric rotating ring 1 9 and the electric rotating ring 2 8 to rotate synchronously, so that the largest support tube drives the bristles 28 to sweep the net cage through the baffle 26, which also facilitates the cleaning of the net cage.

[0044] Specifically, the cage includes an annular tube 11, a hemispherical baffle 10, and a base 13. The lower ends of multiple side tubes 12 are fixedly connected to the side wall of the base 13 at intervals, and the upper ends of multiple side tubes 12 are fixedly connected to the annular tube 11 at intervals. The open end of the baffle 10 is connected to the outside of the annular tube 11. The inner wall and bottom of the baffle 10 are respectively connected to the outside of the side tubes 12 and the base 13. Support tube 1 6 and support tube 2 17 are respectively fixedly connected to both sides of the annular tube 11, which can form a hemispherical cage structure and provide a high-strength mechanical structure.

[0045] Specifically, the first support tube 6 is equipped with an air pipe 3, which is connected to the annular pipe 11 and the air pump 2 respectively. The air pump 2 supplies air to the annular pipe 11 through the air pipe 3. The water inlet pipe 18 and the drain pipe 19 pass through the second support tube 17 and the annular pipe 11 in sequence and enter the net cage. The end of the water inlet pipe 18 is equipped with a screen 14 to prevent the swallowtail pomfret from being sucked in. Furthermore, placing the air pipe 3, the water inlet pipe 18 and the drain pipe 19 in the first support tube 6 and the second support tube 17 respectively can prevent interference when the support rod 7 rotates.

[0046] Specifically, a tow hook 20 is fixed on the side of float 1 or float 2 15 away from the net cage, so that aquaculture personnel can use the tow hook 20 to move the net cage when they receive information that a red tide is about to occur or is about to arrive in the water area.

[0047] Specifically, both buoy 1 and buoy 2 are equipped with photovoltaic panels 5 for power supply and energy storage, utilizing a photovoltaic system for power supply and energy storage, which facilitates electricity use at sea.

[0048] Specifically, both sides of buoy 1 and buoy 2 are connected to pull ropes 22, which are connected to anchor bodies 24. A counterweight 23 is also provided on the pull ropes 22. The pull ropes 22 and anchor bodies 24 can be used to fix the net cage on the sea surface, and the counterweight 23 can be used in conjunction with the rise and fall of the tide to make the buoys move the net cage to float on the sea surface.

[0049] Specifically, the waterproof cover 25 includes a woven layer 253, a waterproof layer 252 is provided on one side of the woven layer 253, and a wear-resistant layer 251 is provided on the opposite sides of the waterproof layer 252 and the woven layer 253, so that the waterproof cover 25 has good flexibility, water resistance and wear resistance.

[0050] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
