Floating net cages are widely used due to their wide range of water depth, convenient management, etc. Floating net cages mainly include anchoring structure, frame structure and netting structure. The anchoring structure fixes the entire net cage in the designated sea area range through anchor blocks and anchor cables.

In addition, in actual marine ranching applications, the net cage is deployed in the open sea for a long time and continuously withstands the cyclic impact of wind, wave and current. Especially in severe sea conditions, the rigid frame is prone to stress concentration due to the lack of buffering and deformation ability. Long-term effect will lead to structural fatigue, weld cracking or connection failure, and then cause frame deformation, damage or even disintegration, which seriously affects the safety and service life of the net cage, and the maintenance cost is high and the repair difficulty is great.

DETAILED DESCRIPTION
[0021] The present application will be further described below in combination with the drawings and examples.
[0022] Example: a breeding net cage,Figure 1 As shown, it comprises: a frame part group, a net part group and an anchoring part group; As shown Figure 2 And Figure 3 As shown, the frame part group comprises: a mounting plate 102; a base 103 fixedly installed on the mounting plate 102, the inside of which is integrated with a positioning module and a sensing module, so that the net cage has the functions of unmanned device docking, real-time water quality monitoring and remote monitoring, providing core support for intelligent breeding management; a float 107 fixedly installed on the mounting plate 102, made of buoyancy material and glass fiber, aiming to ensure structural strength while providing main buoyancy; and a connecting rod 108 fixedly installed in the middle of the base 103 and crossing the float 107 to be connected as a whole; the frame part group is provided with N groups, and N is an integer greater than or equal to four, all the frame part groups together form a circular or regular N-polygon structure, in this embodiment, N is eight and forms a regular octagon structure; if a circle is needed, the connecting rod 108 correspondingly adopts an arc segment; As shown Figure 2 And Figure 3 As shown, the net cage further comprises: a steel cable 101 passing through all the mounting plates 102, so that the edges and corners between the frame part groups form a smooth arc transition, effectively enhancing the deformation adaptability of the structure under dynamic load, thereby improving the overall flexibility; and a buffer spring 109 assembled and fixed between the connecting rods 108 of adjacent two frame part groups, which cooperates with the steel cable 101 to connect all the frame part groups into a flexible whole, and the assembled structure of the buffer spring 109 will realize the modularization of the frame part groups, thereby improving the installation efficiency and convenience between the frame part groups, facilitating transportation and on-site assembly; As shown Figure 1 And Figure 2 As shown, the net part group comprises: a net 104, which is uniformly fixed to the steel cable 101 through a pre-set ring, convenient to install; a bottom frame edge 105 fixedly installed at the bottom of the net 104; and a winch 106 symmetrically assembled and fixed on each base 103, so that the winch 106 can be interchangeably installed on the base 103 of different net cages without being placed on the sea for a long time, realizing "use and install at the same time", improving its use flexibility and service life; the net 104 is provided with a winding rope matched with the winch 106, which is detachably connected with the winch 106 and the bottom frame edge 105 through a snap ring and a ring head, and passes through the ring provided on the net 104 to realize the folding of the net 104, and the base 103 is provided with a buckle head for fixing the winding rope; As shown Figure 1 As shown, the anchoring part group comprises: an anchor block 110 and an anchor cable 111, the two ends of the anchor cable 111 are connected with the anchor block 110 and the base 103 respectively; this embodiment is provided with four groups of anchoring part groups, which are symmetrically distributed on the frame part groups, and together anchor the net cage stably in the predetermined sea area.
[0023] The net cage can be transported to the target sea area in a disassembled state and quickly assembled on site. After assembly, the anchor block 110 is sunk to the seabed, and the frame group is constrained by the anchor cable 111, thereby achieving precise positioning and mooring of the net cage in the sea. The frame group floats on the sea surface, providing continuous and stable support for the netting 104, forming a reliable breeding enclosure space, and ensuring that the breeding products are in a safe and controllable marine environment. When the net cage is subjected to severe and high-frequency wave impact, the frame group on the wave-impingement side will displace relative to the adjacent frame group. At this time, the buffer spring 109 effectively absorbs and disperses the impact energy through its elastic deformation, achieving efficient dissipation and buffering of the impact force, thereby avoiding plastic deformation or damage of the overall structure due to instantaneous overload. After the wave action weakens, the frame groups can quickly reset under the restoring force of the buffer spring 109, restoring the overall net cage to its original design form and providing structural support for subsequent operations.
[0024] When the netting 104 needs to be retracted, the winch 106 is installed on the base 103, and the winding rope is disconnected from the clasp on the base 103 and connected to the winch 106. Then, the winch 106 is started to wind the winding rope, pulling the bottom frame edge 105 upwards to gradually retract the netting 104 and achieve the closing operation of the breeding area. After completing the retraction of the netting 104, two cases are handled according to actual operation requirements: if the net cage needs to continue offshore operations, control the winch 106 to release the winding rope, allowing the netting 104 to re-expand, then fix the end of the winding rope to the clasp on the base 103, and remove the winch 106 for use in other net cages. Second, if the netting 104 needs to be retracted, the bottom frame edge 105 should be connected to the steel cable 101 with a fixing rope before releasing the winding rope to assist in maintaining the retracted state. Then, fix the end of the winding rope to the clasp on the base 103 and remove the winch 106. When the netting 104 in the retracted state needs to be re-expanded, it is necessary to confirm that the end of the winding rope is still fixed to the clasp on the base 103, and then remove the fixed connection between the bottom frame edge 105 and the steel cable 101. The netting 104 naturally expands under the action of its own weight and external water flow, restoring its breeding enclosure function. This design allows the modular use of the winch 106, which can be used in multiple net cages, reducing overall configuration costs and achieving efficient sharing and utilization of resources.
[0025] Through the positioning module in the base 103, the net cage can establish high-precision docking with unmanned devices such as unmanned ships and unmanned aerial vehicles, support automatic baiting, water sampling, aerial inspection and other operations; through the deployed sensing module, key water quality parameters including water temperature, pH value, dissolved oxygen, salinity and the like are collected in real time and transmitted to a cloud system such as a shore-based or cloud control platform, and the cloud system automatically analyzes the breeding environment state according to the monitoring data, dynamically adjusts the feeding amount, oxygenation machine start-stop and circulating water flow intensity, realizes precise regulation and control of the breeding process; finally, real-time diagnosis and multi-level alarm will be performed on abnormal data (such as too low dissolved oxygen, temperature mutation), and remote intervention or automatic start of emergency oxygenation and other response mechanisms are supported. Therefore, through the cooperative operation of the above modules and the cloud system, the net cage will build a remote intelligent management system integrating monitoring, analysis, control and early warning, thereby improving the precision, reliability and operation efficiency of the breeding operation.
[0026] The net cage realizes flexible connection of the frame assembly by using the buffer spring 109, so that the overall structure can effectively absorb the impact energy of sea waves, convert rigid collision into elastic deformation, and improve the wind and wave resistance and structural durability of the net cage, fundamentally solving the problem of easy fatigue damage of the traditional rigid enclosure.
[0027] The net cage realizes real-time sensing and precise regulation and control of the breeding environment through the integrated intelligent monitoring and control system, and can cooperate with various unmanned devices such as unmanned ships and unmanned aerial vehicles, further expanding the monitoring range and response efficiency; this design can greatly improve the automation level of the net cage management and the controllability of the breeding process, providing more efficient and reliable equipment support for deep-sea intelligent breeding.
[0028] For example, Figure 4 and Figure 5As shown, the net cage further comprises: a mounting block 201 fixedly installed at both ends of the buffer spring 109; a mounting sleeve 203 fixed at a corresponding position of the connecting rod 108, the mounting block 201 being insertedly matched with the mounting sleeve 203; a bayonet 204 insertedly matched between the mounting block 201 and the mounting sleeve 203 to lock the mounting block 201 on the mounting sleeve 203, that is, under the matching structure among the mounting block 201, the mounting sleeve 203 and the bayonet 204, the buffer spring 109 is detachably assembled so as to conveniently replace the buffer spring 109 with performance attenuation or damage during the regular maintenance of the buffer spring 109; and a protective sleeve 202 covering the buffer spring 109, having a deformation characteristic and being fixedly matched with the mounting sleeve 203, which can effectively isolate seawater and prevent marine organisms from attaching and eroding the buffer spring 109, thereby prolonging the service life of the buffer spring 109 and reducing long-term maintenance costs.
[0029] The modular and detachable design of the buffer spring 109 and the addition of the protective sleeve 202 greatly improve the maintenance convenience and environmental resistance of the key buffer components of the net cage, so as to ensure long-term and stable buffering performance.
[0030] As shown in Figure 1 and Figure 6 , the net cage further comprises: a photovoltaic panel 301 fixedly installed on the base 103, for efficiently converting light energy into electric energy, an energy storage battery electrically connected with the photovoltaic panel 301 being arranged in the base 103, the photovoltaic panel 301 delivering the converted electric energy to the battery for energy storage, thereby providing sustained and clean power supply for various modules inside the base 103, significantly enhancing the energy self-sufficiency and ocean operation endurance of the net cage; a signaler 302 fixedly installed on the base 103, which is a comprehensive signal receiver, effectively improving the strength and stability of data transmission signals by combining a high-gain antenna with a low-noise amplifier, and internally built with a multi-frequency GPS / Beidou positioning chip to realize real-time tracking and coordinate feedback of the position of the net cage, and support microwave emission in a specific frequency band to establish a low-latency and anti-interference data transmission channel in complex sea conditions, thereby further expanding the collaborative operation capability of the net cage with intelligent devices such as unmanned ships and unmanned aerial vehicles, providing them with sustained and stable communication relay and position reference, and ensuring reliable bidirectional transmission of monitoring data and control instructions in the breeding sea area; an indicator light 303 fixedly installed on the base 103, supporting active light emission at night or in low-visibility environments; the indicator light 303 adopts a three-color light design, different color combinations of multiple groups of lights are used to distinguish different operation areas, which facilitates intelligent devices such as unmanned aerial vehicles to quickly identify and accurately position specific net cages, greatly improving the safety and operation efficiency of night navigation and operation.
