Description

Technical Field

[0001] This invention relates to the technical field of aquaculture, and in particular to a controllable floating and flipping oyster cage culture device and its early warning and control method. Background Technology

[0002] Oyster farming methods are mainly divided into two categories: bottom-seeding and off-bottom farming. Large-scale artificial oyster farming mostly adopts off-bottom farming. Common off-bottom farming methods include raft farming, net cage farming, and bamboo-insertion farming. Net cage farming detaches the oysters from their substrate, allowing them to grow individually within the cage. Oyster growth is not limited by space, allowing them to fully utilize their individual growth potential, resulting in faster growth, higher yields, and higher quality. However, the production process requires periodic turning of the oyster cages and reliance on natural tides to move the oysters in and out of the water. Therefore, traditional oyster cage farming has the following problems:

[0003] a) Fixed oyster cages are devices located in the intertidal zone that cannot be automatically turned over, requiring a large amount of manual turning and cleaning of the oyster cages.

[0004] b) Oyster cages with buoyancy structures in the intertidal zone can be turned over and moved in and out of the water by tides, but they are affected by tides and cannot be controlled by humans. If there is a sudden drop in salinity and it is necessary to raise the cage to avoid danger, it cannot be controlled by humans.

[0005] c) Oyster cages with buoyancy structures located on the sea surface (non-tidal areas) require manual labor and special aquaculture vessels for raising, lowering, and turning over, and the labor intensity of offshore operations remains relatively high.

[0006] Therefore, developing a controllable snorkeling and flipping oyster cage culture device is beneficial for saving labor and improving the quality of oyster farming. Summary of the Invention

[0007] The primary objective of this invention is to overcome the shortcomings of existing technologies and provide a controllable floating and flipping oyster cage culture device, which enables remote control of oyster cage entry, exit from water, and flipping, effectively improving the level of intelligent oyster farming.

[0008] The second objective of this invention is to provide an early warning control method for a controllable snorkeling and flipping oyster cage culture device.

[0009] The first objective of this invention is achieved through the following technical solution:

[0010] A controllable snorkeling and flipping oyster cage culture device includes a main float, a snorkeling mechanism, oyster cages, a float, a control unit, and a power supply unit. At least one snorkeling mechanism is hinged to the main float, and each snorkeling mechanism has at least one oyster cage. One end of each oyster cage is hinged to the snorkeling mechanism, while the other end is a free end equipped with a float. The power supply unit is electrically connected to both the snorkeling mechanism and the control unit to provide power. The control unit is communicatively connected to the snorkeling mechanism to control the water intake and drainage within the snorkeling mechanism based on real-time aquaculture environment data, thereby controlling the oyster cage's entry and exit from the water. An alarm is triggered when the aquaculture environment data exceeds preset values.

[0011] Furthermore, the snorkeling mechanism includes a snorkeling hinge plate, a snorkeling tube, a mounting rod, a first buoyancy switch sensor, and a second buoyancy switch sensor. The snorkeling hinge plate has an L-shaped structure, with the snorkeling tube located at the corner of the L-shape. One end of the L-shape is hinged to the main float, and the other end has a mounting rod for installing oyster cages. The first buoyancy switch sensor is hinged to one side of the L-shape of the snorkeling hinge plate, near the hinge axis. The second buoyancy switch sensor is hinged to the other side of the L-shape of the snorkeling hinge plate, near the corner. Two buoyancy switch sensors are connected to the control unit. The snorkeling status of the snorkeling tube is determined based on the on / off status of the two buoyancy switch sensors. When the water inside the snorkeling tube is emptied, the snorkeling hinge plate rotates upward around its hinge axis with the main float under the action of buoyancy, and drives the oyster cage to rotate upward until the oyster cage is completely out of the water. When the water inside the snorkeling tube is full, the snorkeling hinge plate rotates downward around its hinge axis with the main float under the action of gravity, and drives the oyster cage to rotate downward until the oyster cage is completely submerged in the water, finally achieving the flipping of the oyster cage.

[0012] Furthermore, the snorkeling tube includes a tube body, an air vent, a water inlet, a drainage pipe, a water inlet pump, a water inlet valve, a drainage pump, and a drainage valve. The water inlet, air vent, and drainage pipes are respectively installed on the tube body. The water inlet is equipped with a water inlet pump and a water inlet valve, and the drainage pipe is equipped with a drainage pump and a drainage valve. The water inlet pump, water inlet valve, drainage pump, and drainage valve are controlled by a control unit to control the snorkeling tube's ascent and descent.

[0013] Furthermore, the control unit includes a control module, a sampling module, a communication module, and an alarm module. The control module is used to control the movement and posture of the entire machine. The sampling module is used to collect real-time aquaculture environment data. The communication module is used for communication between the control module and the snorkeling mechanism. The alarm module is used to issue an alarm when the aquaculture environment data exceeds a preset value.

[0014] Furthermore, the sampling module includes an oxygen sensor for collecting oxygen content in the aquaculture water, an air temperature sensor for collecting ambient air temperature, a water temperature sensor for collecting aquaculture water temperature, a turbidity sensor for collecting microbial content in the aquaculture water, a salinity sensor for collecting aquaculture water salinity, and an ambient atmospheric pressure sensor for collecting ambient atmospheric pressure.

[0015] Furthermore, the main floating frame has an I-shaped structure and consists of a first floating frame and a second floating frame vertically connected to both ends of the first floating frame.

[0016] Furthermore, the control unit and the power supply unit are mounted on top of the main floating frame via mounting brackets.

[0017] Furthermore, the mounting bracket includes an electrical bracket and a hoisting bracket. The bottom end of the hoisting bracket is connected to the main floating frame, and its top end is connected to the bottom end of the electrical bracket. The control unit and the power supply unit are mounted on the electrical bracket.

[0018] Furthermore, the power supply unit includes a battery and a solar panel for replenishing the battery.

[0019] The second objective of this invention is achieved through the following technical solution:

[0020] A controllable snorkeling flipping oyster cage culture device and its early warning and control method, comprising,

[0021] The sampling module of the control unit collects real-time aquaculture environment data, and performs mean filtering on the data to avoid noise interference. The real-time aquaculture environment data includes oxygen content, temperature, microbial content, salinity, ambient temperature, and atmospheric pressure in the aquaculture water.

[0022] When the oxygen content of the aquaculture water is less than the preset oxygen content value, or the temperature of the aquaculture water is greater than the preset water temperature value, or the salinity of the aquaculture water exceeds the preset salinity range, or the atmospheric pressure drop gradient is greater than the preset drop value, the alarm module of the control unit will sound an alarm and wait for the user to perform manual control operation. After the preset time, if the user does not operate, the control unit will control the snorkeling mechanism to drain the water. When the water inside the snorkeling mechanism is drained, the snorkeling mechanism will rotate upward around the hinge axis with the main float under the action of buoyancy, and drive the oyster cage to rotate upward until the oyster cage is completely out of the water surface, completing the oyster cage lifting operation.

[0023] When the outside temperature is higher than the preset temperature value, the alarm module of the control unit will sound an alarm and wait for the user to perform manual control operation. After the preset time, if the user does not operate, the control unit will control the snorkeling mechanism to enter water. When the snorkeling mechanism is full of water, the snorkeling mechanism will rotate downward around the hinge axis between itself and the main float under the action of gravity, and drive the oyster cage to rotate downward until the oyster cage is completely submerged in the water, thus completing the oyster cage entering the water operation.

[0024] When the microbial content in the aquaculture water exceeds the preset turbidity value, the alarm module of the control unit will sound an alarm to remind the user to replenish the nutrient solution or change the aquaculture location.

[0025] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0026] 1. The cage culture device of the present invention can be arranged in the non-intertidal zone. Through remote control of the cage culture device, the oyster cages can be watered, dried and turned over, which reduces the labor cost of farming and improves the level of intelligence in oyster farming.

[0027] 2. The cage culture device of the present invention has a simple and reliable structure and strong resistance. The raising and lowering of the oyster cage can be reliably realized by controlling the water inlet and outlet of the floating tube, effectively avoiding problems such as jamming, lubrication and pollution caused by other mechanisms. Moreover, the up and down flipping of the cage culture device and the water inlet and outlet of the oyster cage are autonomously controllable. When the aquaculture water encounters a sudden low salinity, the water can be lifted with one button, which has good reliability.

[0028] 3. The electrical control part of the present invention is mounted on the main floating frame. The up and down movement on both sides will not affect the electrical control part, and the electrical control part will not fall into the water, thus improving the safety of the electrical control part.

[0029] 4. The snorkeling mechanism of the present invention adopts a symmetrical arrangement on both sides, which effectively avoids the occurrence of side-falling. Even when both sides sink to the limit state, there will be no tilting or overturning, and it has good stability.

[0030] 5. The cage-raising device of the present invention has the advantage of being movable, and can be moved into the inner bay in the event of a storm.

[0031] 6. The cage-raising device of the present invention can be used in combination on a large scale or used alone, and its layout is convenient. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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 some embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0045] Example 1:

[0046] like Figures 1 to 4As shown, this embodiment provides a controllable snorkeling and flipping oyster cage culture device, including a main float 1, a snorkeling mechanism, multiple oyster cages 7, floats 8, a control unit, and a power supply unit. The main float 1 provides buoyancy. There is at least one snorkeling mechanism; this embodiment uses two as an example. The two snorkeling mechanisms are symmetrically hinged to the left and right sides of the main float 1. Each snorkeling mechanism is equipped with at least one oyster cage 7, and one end of each oyster cage 7 is hinged to the snorkeling mechanism, while the other end is a free end equipped with a float 8. Under the action of the float 8, the other end of the oyster cage 7 can always be close to the water surface. The power supply unit is electrically connected to the snorkeling mechanism and the control unit to provide power. The control unit is communicatively connected to the snorkeling mechanism to control the water intake and drainage inside the snorkeling mechanism based on real-time aquaculture environment data, thereby controlling the oyster cage entry and exit operations, and triggering an alarm when the aquaculture environment data exceeds a preset value.

[0047] The snorkeling mechanism includes a snorkeling hinge plate 2, a snorkeling tube 3, a mounting rod 4, a first buoyancy switch sensor 5, and a second buoyancy switch sensor 6. The snorkeling hinge plate 2 has an L-shaped structure, and the snorkeling tube 3 is located at the corner of the L-shaped structure. The snorkeling mechanism can descend and ascend by controlling the water inlet and outlet of the snorkeling tube 3. One end of the L-shaped structure is hinged to the main float 1, and the other end is equipped with a mounting rod 4 for installing the oyster cage 7. The first buoyancy switch sensor 5 is hinged to one side of the L-shaped structure of the snorkeling hinge plate 2 and close to the hinge axis. The second buoyancy switch sensor 6 is hinged to the other side of the L-shaped structure of the snorkeling hinge plate 2 and close to the corner. The two buoyancy switch sensors are connected to the control unit, and the snorkeling status of the snorkeling tube 3 is determined based on the on / off status of the two buoyancy switch sensors. When the water inside the snorkel tube is emptied, the snorkeling hinge plate rotates upward around its hinge axis with the main float 1 under the action of buoyancy, and drives the oyster cage 7 to rotate upward until the oyster cage 7 is completely out of the water surface and hangs on the hook rod 4 under the action of the float 8 and gravity. When the water inside the snorkel tube is full, the snorkeling hinge plate rotates downward around its hinge axis with the main float 1 under the action of gravity, and drives the oyster cage 7 to rotate downward and submerge in the water. Under the action of the buoyancy of the float 8, the oyster cage 7 flips around the hook rod 4 until the oyster cage 7 is completely submerged in the water surface, finally realizing the flipping of the oyster cage 7.

[0048] like Figure 5 As shown, the snorkeling tube 3 includes a tube body b, an air duct a, a water inlet duct c, a drain duct h, a water inlet pump e, a water inlet valve d, a drain pump f, and a drain valve g. The water inlet duct, air duct, and drain duct are respectively installed on the tube body. The water inlet duct is equipped with a water inlet pump and a water inlet valve, and the drain duct is equipped with a drain pump and a drain valve. The water inlet pump, water inlet valve, drain pump, and drain valve are controlled by a control unit to control the snorkeling tube's ascent and descent.

[0049] like Figures 6 to 9 As shown, when both buoyancy switch sensors are closed, the snorkeling tube 3 is in a "fully submerged" state; when both buoyancy switch sensors are open, the snorkeling tube 3 is in a "surfacing" state; and when the first buoyancy switch sensor 5 is open and the second buoyancy switch sensor 6 is closed, the snorkeling tube 3 is in a "partially submerged" state.

[0050] The control unit includes a control module, a sampling module, a communication module, and an alarm module. The control module is used to control the movement and posture of the whole machine. The sampling module is used to collect real-time aquaculture environment data. The communication module is used for communication between the control module and the snorkeling mechanism. The alarm module is used to issue an alarm when the aquaculture environment data exceeds a preset value.

[0051] The sampling module includes an oxygen sensor for collecting oxygen content in the aquaculture water, an air temperature sensor for collecting ambient air temperature, a water temperature sensor for collecting aquaculture water temperature, a turbidity sensor for collecting microbial content in the aquaculture water, a salinity sensor for collecting aquaculture water salinity, and an ambient atmospheric pressure sensor for collecting ambient atmospheric pressure.

[0052] The main floating frame 1 has an overall I-shaped structure and is composed of a first floating frame 101 and a second floating frame 102 vertically connected to both ends of the first floating frame.

[0053] like Figures 10 to 11 As shown, the control unit can be set to automatic or manual control. If manual control is selected, the oyster cages' water inlet and outlet are controlled manually. When the user selects automatic control, the system will first enter the automatic control settings, which are defaulted to controlling the oyster cages' water inlet and outlet according to tidal rhythms. Users can also set the oyster cages' water inlet and outlet times themselves; once set, the device will then control the water inlet and outlet according to the settings.

[0054] The control unit and power supply unit are mounted on the main floating frame 1 via mounting brackets. The control unit can be installed inside the electrical control box 13 according to the actual situation. The mounting brackets include an electrical bracket 11 and a hoisting bracket 12. The hoisting bracket 12 facilitates the transportation and installation of the whole machine. Its bottom end is connected to the main floating frame 1, and its top end is connected to the bottom end of the electrical bracket 11. The electrical control box 13 and the power supply unit are mounted on the electrical bracket 11.

[0055] The power supply unit includes a battery 9 and a solar panel 10 for replenishing the battery 9.

[0056] Example 2:

[0057] like Figure 12 As shown, this embodiment provides an early warning control method for a controllable snorkeling and flipping oyster cage culture device, including:

[0058] A sampling module was used to collect real-time aquaculture environment data. The data was then filtered to avoid noise interference. The real-time aquaculture environment data included oxygen content, temperature, microbial content, salinity, ambient temperature, and atmospheric pressure in the aquaculture water.

[0059] When the oxygen content of the aquaculture water is less than the preset oxygen content value (in this embodiment, the preset oxygen content value is 2 ppm), or when the temperature of the aquaculture water is greater than the preset water temperature value (in this embodiment, the preset water temperature value is 25°C), or when the salinity of the aquaculture water exceeds the preset salinity range (in this embodiment, the preset salinity range is 20-35 ppt), or when the atmospheric pressure drop gradient is greater than the preset drop value (in this embodiment, the preset drop value is 10 hpa / h), the alarm module will sound an alarm and wait for the user to perform manual control operation. After 10 minutes, if the user does not operate, the control unit will control the snorkeling mechanism to drain water. When the water inside the snorkeling mechanism is drained, the snorkeling mechanism will rotate upward around the hinge axis with the main float under the action of buoyancy, and drive the oyster cage to rotate upward until the oyster cage is completely out of the water surface, completing the oyster cage lifting operation.

[0060] When the outside temperature is higher than the preset temperature value (30°C in this embodiment), the alarm module of the control unit will sound an alarm and wait for the user to perform manual control operation. If the user does not operate after 10 minutes, the control unit will control the snorkeling mechanism to enter water. When the snorkeling mechanism is full of water, the snorkeling mechanism will rotate downwards around the hinge axis with the main float under the action of gravity, and drive the oyster cage to rotate downwards until the oyster cage is completely submerged in the water, thus completing the oyster cage entering the water operation.

[0061] When the microbial content in the aquaculture water exceeds the preset turbidity value (in this embodiment, the preset turbidity value is 2 NTU), the alarm module of the control unit will issue an alarm to remind the user to replenish the nutrient solution or change the aquaculture location.

[0062] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and inventive concept of the present invention, shall fall within the scope of protection of the present invention.
