Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of deep - sea aquaculture, and more specifically, to an intelligent deep - sea submersible aquaculture cage. Background Art
[0002] Traditional cage aquaculture is usually set in coastal waters. Seawater can flow freely inside and outside the cage through the fishing net. This method can not only smoothly carry out seawater exchange and oxygen supply to ensure the metabolism of fish, but also the waste and food residues of fish can sink to the bottom through the mesh, without the need to separate the waste and residues. Therefore, even in a small cage space, a large number of fish can be cultured, and the water quality in the aquaculture area will not deteriorate sharply, which has the advantages of large - scale fishery aquaculture. However, if the coastal aquaculture areas are too dense, a large amount of waste and residues will be discharged at the same time, which will lead to the pollution of the coastal beach water quality in the long run and is not conducive to environmental protection.
[0003] For deep - sea aquaculture, its water quality is better than that of coastal waters. At the same time, the movement of ocean currents can bring certain plankton to supplement food for fish, which is easy to form an open - type ecological aquaculture mode to achieve high - quality and high - yield fishery aquaculture. The existing aquaculture cages are fixed by anchors and ropes on the seabed and can only be used in coastal areas or waters with small waves. They are easily impacted by strong winds and waves in the deep - sea, resulting in the overturning, rupture or even loss of the cages. Therefore, traditional coastal aquaculture cages are not suitable for deep - sea aquaculture.
[0004] In addition, deep - sea aquaculture requires many factors, such as temperature, depth, water quality, dissolved oxygen, salinity, etc. Different fish have different requirements for the growth environment, and it is particularly necessary to monitor the information of the aquaculture area. Traditional aquaculture methods have problems such as low efficiency, resource waste, environmental pollution, etc. Therefore, it is necessary to develop precision aquaculture technology to improve the sustainability and economic benefits of aquaculture.
[0005] Patent CN213095562U discloses a method of installing floating pipes around the cage to adjust the lifting of the cage by buoyancy, and patent CN117441651A discloses a lifting cage based on a sliding track type, and the support piles are generally installed on the wind turbines of the wind farm. However, the former has the problem of poor control of the sinking and floating performance of the cage, and the latter has the problems of cumbersome operation and high cost. In particular, if the cage does not lift smoothly and causes deflection, if the disturbance is too large, it is easy to frighten or harm the fish.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0038] See Figure 1 As shown, the present invention discloses an intelligent deep - sea submersible aquaculture cage, including: cage fence support 1, sealed control room, central control system 2, fiber mesh netting 3, diving tank 4, chassis 5, rope 6, anchor block 7; wherein, the cage is surrounded by a cage fence support 1 composed of a circular metal structure, the sealed control room is arranged on the top platform of the cage fence support 1 and internally contains the central control system 2; the fiber mesh netting 3 is fixedly surrounded by detachable connectors on the outer edge of the cage fence support 1; the diving tank 4 is arranged in the middle of the cage and is connected to the cage fence support 1 by welding; the chassis 5 is a basic platform composed of a cross - shaped reinforcing beam and is rigidly connected to the cage fence support through a metal structure support 8; one end of the rope 6 is radially connected to the chassis 5 and the other end is connected to the anchor block 7.
[0039] Specifically, the cage fence support 1, the sealed control room, the diving chamber 4, the fiber net clothing 3, the chassis 5, and the ropes 6 are all made of rigid materials.
[0040] The chassis 5 is a high-strength chassis with a relatively low density.
[0041] Furthermore, the diving chamber 4 is modular and detachable, and is installed on the skeleton structure of the cage. It is installed quantitatively after calculation according to the size of the cage and the aquaculture sea area.
[0042] Furthermore, the specific content of the quantitative installation is as follows:
[0043] The force requirement for the cage to be stationary in water: F = G + αG1 = Vρ s g
[0044] The demand algorithm for the diving chamber is calculated according to the following formula:
[0045]
[0046] Among them, F is the buoyancy, n is the number of diving chambers, v is the volume of the cage, v1 is the empty volume of the diving chamber, ρ s is the sea water density, ρ is the overall density of the cage, ρ1 is the density of the diving chamber body, α is the allowable buoyancy difference coefficient, G is the overall gravity of the cage, G1 is the empty gravity of the diving chamber, V is the drainage volume of the cage in water, and g is the acceleration due to gravity.
[0047] Specifically, v is the volume of the cage, which can be measured in advance; ρ s is the sea water density, which is directly measured by a sensor; ρ is the overall density of the cage, which depends on the materials used for the cage; α is the allowable buoyancy difference coefficient, which gives the cage a small upward buoyancy to avoid sinking to the bottom of the sea and is usually calculated according to requirements.
[0048] Specifically, Figure 2a is a schematic diagram of the working state of the water storage tank and the ballast tank when sinking, Figure 2b is a schematic diagram of the working state of the water storage tank and the ballast tank when rising, Figure 2c is a working flow chart for sinking, Figure 2dIt is the working flow chart for ascending. The control principle for the ascent or descent of the cage: When there is a need for descent, the air compressor starts to pump air into the ballast tank. The air pressure in the water storage tank decreases. At the same time, the water pump can more easily pump seawater into the water storage tank. The self-weight of the entire diving chamber 4 increases, the rope 6 tightens and shortens, and the cage as a whole sinks. When it sinks to an appropriate depth, the diving chamber 4 closes and the rope 6 is locked. The cage is in a state of balanced force under the action of buoyancy and the tension of the rope 6 and is relatively stationary. When there is a need for ascent, the diving chamber 4 drains water, its self-weight decreases, and the buoyancy increases. At the same time, the rope 6 relaxes and starts to float under the action of buoyancy. When it floats to the target height, the diving chamber 4 closes and the rope 6 is locked. The cage is in a state of balanced force under the action of buoyancy and the tension of the rope 6 and is relatively stationary. Figure 3a It is a schematic diagram of the working states of the diving chamber and the winch when the cage sinks. Figure 3b It is a schematic diagram of the working states of the diving chamber and the winch when the cage ascends. Figure 3c It is a schematic diagram of the working states of the diving chamber and the winch when the cage is in static balance.
[0049] Further, as shown in Figure 4 The central control system includes: a bait feeder, a bait feeding pipeline, a rope winch, a communication system, an on-board computer, sensors, and a power storage system. The on-board computer, as the main control terminal, is connected to the bait feeder, the bait feeding pipeline, the rope winch, the communication system, the sensors, and the power storage system through signal cables; the bait feeder and the power storage system are arranged in the sealed control room in the middle of the cage; the rope winch is arranged at the bottom of the cage; the sensors are arranged around the cage.
[0050] Specifically, when conducting aquaculture on the sea surface, power is transmitted through methods such as wind power, photovoltaic power, and wave energy, and electrical energy is stored through a storage battery; the on-board computer realizes remote monitoring and operation management of the device terminals through the Internet of Things.
[0051] Further, the bait feeder is set to feed at a fixed time, and the bait is put into the cage through the bait feeding pipeline to achieve unattended operation;
[0052] The sensors obtain hydrological information, water quality information, and fish farming information and transmit them to the control center through the communication system;
[0053] The power storage system generates and stores electricity through methods such as wind power, photovoltaic power, and wave energy;
[0054] When a typhoon comes, the on-board computer calculates the drainage / water injection volume of the diving chamber and calculates the sinking / ascending distance in real time according to the length of the rope 6.
[0055] Further, the anchor block 7 is manufactured by the die method, and the anchor block 7 is installed with a rope 6 mooring joint for fixing the cage rope 6.
[0056] Further, the motor for the rope 6 is a waterproof motor.
