The present disclosure relates to the technical field of an aquaculture system, and particularly relates to a depth wire-controlled aquaculture device that controls the underwater depth of the net cage by drawing or releasing the connection wire of the net cage.
With the rapid expansion of the global population, the rate of consumption of edible aquatic products has accelerated with the increase in the total population. In addition, in recent years, due to the overfishing, the pollution of the marine environment and the impact of global climate change, natural fishery resources are increasingly scarce, and in order to make up for the huge demand for edible aquatic products, global aquaculture fisheries accordingly grows rapidly.
At present, the conventional sinking/floating net cage is still technically immature in use. The conventional sinking/floating net cage at least includes a net bag, a floating frame unit and a hollow tube. The floating frame unit can float on a sea surface. The net bag is arranged around the floating frame unit and forms a breeding space. The hollow tube is arranged around the floating frame unit. Because the conventional sinking/floating net cage cannot automatically float up or sink down and is mostly placed on the sea for a long time, the conventional sinking/floating net cage is often difficult to withstand the impact of the waves for a long time when facing typhoons or periodic monsoon waves, causing the sinking/floating net cage to move freely from the original breeding site. Thus, it causes heavy losses to fish farmers, and even more because the net bag ruptured, causing a large number of fish to escape, the yielding rate of fish farming is affected. In addition, every marine organism has a suitable ocean depth position for life, and the conventional sinking/floating net cage cannot adjust the ocean depth position of the sinking/floating net cage at any time, which makes it difficult to breed marine organisms of different ocean depths. Therefore, how to use innovative hardware design to effectively improve the mobility of the conventional sinking/floating net cage to cope with various situations that may cause fish farmers to lose fish and to expand the species of marine organisms in different ocean depths, is an issue that related industry developers and related researchers need to continue to work hard to overcome and solve.
In view of this, the purpose of the present disclosure is to provide a depth wire-controlled aquaculture device, which can instantly adjust the underwater depth of the net cage according to the marine environment and aquaculture conditions, and thus the depth environment that various aquatic products can adapt to is adjusted, so as to avoid the impact of various sea conditions on breeding.

The net cage 10 includes a frame 11 and a net body 12, and the net body 12 is set on the frame 11. The net body 12 forms a breeding space around the frame 11. In implementation, the net body 12 can prevent the fish in the breeding space from escaping. The frame 11 is further surrounded by a plurality of floating tubes (not shown in the drawings). The floating tubes form a ring structure with each other. The ring structure is disposed on the internally formed breeding space, which is beneficial for fish farmers to stand and work on the frame 11. There can be an armrest at the upper end of frame 11 (not shown in the drawings). When the net cage 10 is shaken by waves or ocean currents, the fish farmer can use the armrest to keep standing on frame 11 and work to avoid the fish farmer to fall down due to instability.
The depth sensor 20 is set in the net cage 10 to detect the underwater depth of the net cage 10 and generate a depth signal. The float balls 30 are connected to the frame 11 of the net cage 10, and the buoyancy generated by the float balls 30 supports the weight of the net cage 10. The float balls 30 of this embodiment support a part of the weight of the net cage 10. The depth sensor 20 can be a piezoelectric IC or a strain gauge, and the value of the underwater depth (i.e. the depth under the water surface) is obtained by detecting the water pressure.
The wire control module 40 includes a controller 41, a reel 42, a driver 43, and a connection wire 44. The connection wire 44 is connected to the net cage 10 and wound around the reel 42. The controller 41 is electrically connected to the depth sensor 20 and the driver 43, the depth signal is transmitted to the controller 41, and the controller 41 compares the depth signal with a setting value, and controls the driver 43 according to the comparison result, or the controller 41 controls the driver 43 according to the externally transmitted control signal, so that the driver 43 drives the reel 42 to rotate to draw or release the connection wire 44 to change the underwater depth of the net cage 10. The driver 43 can be, for example, a servo motor, the reel 42 can be, for example, a hub-shaped member, and the connection wire 44 can be a cable or an iron chain. The force applied on the net cage 10 includes the weight of the net cage 10, the buoyancy of the water acting on the float balls 30, and the pulling force applied on the net cage 10 by the connection wire 44. Therefore, when wanting the net cage 10 to stay in any position underwater, the force applied to the net cage 10 should achieve the force balance state. Therefore, the weight of the net cage 10 is equal to the sum of the buoyancy of the float balls 30 and the pulling force of the connection wire 44, so that the reel 42 can adjust the position of the net cage 10 underwater when the connection wire 44 is drawn or released. On the other hand, because tension must be generated on the connection wire 44 so that the position of the net cage 10 underwater can be adjusted by drawing or releasing connection wire 44, the buoyancy generated by all float balls 30 must be set to be less than the weight of the net cage 10.

These data are stored in the data storage unit 56 by the control of the second processing module 51, or browsed and analyzed by the fish farmer via the imaging unit 57, and the fish farmer can operate the operating unit 55 and generate an operating command. The first wireless communication module 413 transmits the operating command to the processing module 411 via the second processing module 51 and the second wireless communication module 54. The processing module 411 and the programmable controller module 412 controls the driver 43 to rotate the reel 42 to draw or release the connection wire 44 according to the operating command to make the net cage 10 float up or sink down. The marine environment monitoring system 50 can receive the acceleration signal generated by the accelerometer 415 according to the movement state of the net cage 10 via the second wireless communication module 54, so that the fish farmer can monitor the acceleration signal of the accelerometer 415 via the marine environment monitoring system 50 and operate the operating unit 55 to control the movement state of the net cage 10, and then adjust the tilted angle of the net cage 10 to balance the tilted angle. The fish farmer can understand the current operating status of the net cage 10 via the depth signal and acceleration signal; or the fish farmer can use the operating unit 55 to control the net cage 10 to flow up, sink down or keep the current status; or the fish farmer can set the parameter setting unit 53 to monitor the operating status of the net cage 10 or to automatically adjust the operation of the net cage 10.
