[0002] The offshore wind farm is used for offshore wind power generation; at the same time, for the fishery net cage culture in the deep sea area, because it is in the deep sea, the net cage is subjected to large marine environmental loads such as wind, wave and current, which will increase the cost of the net cage anchoring system. In addition, the deep-sea aquaculture is far away from the land, and if there is a lack of power supply, the deep-sea aquaculture industry cannot be equipped with advanced offshore fishery aquaculture equipment, and the labor cost is reduced. Therefore, the offshore wind farm is usually combined with the fishery net cage culture.

However, the structure needs to be provided with four steel pipe piles to maintain the balance of the net cage lifting, and when the steel pipe pile is attached with biological shells and the like, the aquaculture net cage is easy to be stuck, so that the net cage cannot be smoothly lifted and moved. In addition, for some large fishery net cages, a large area of netting is welded and assembled with support columns, for example, a deep-sea lifting type aquaculture net cage proposed by Chinese invention patent application CN115281133A, the netting is inconvenient to replace, and the maintenance cost is high; for example, a deep-sea aquaculture net cage capable of simultaneously culturing fish and scallops proposed by Chinese invention patent application CN113693003A, the entire netting is replaced by using the cooperation between the slide rail and the motor, and when the netting is partially damaged, the entire netting needs to be replaced, so that the maintenance cost of the entire net cage is increased.

[0041] That is, the bottom of the support pile 10 is adapted to be fixed on the base of the fan of the wind farm, facilitating the installation of the net cage 30 and the feeding mechanism 40; the plurality of net clothes 306 are detachably assembled on the main frame 301 of the net cage 30 to form the culture cavity for the culture of the culture objects, and the net clothes 306 can be quickly disassembled to facilitate the installation and replacement; the elastic elements 201 and the rolling elements 202 are arranged in the passage 302 of the net cage 30 to enable the floating rolling contact between the net cage 30 and the support pile 10, when there are attachments on the support pile 10, the net cage 30 can roll over the attachments to maintain the balance of the net cage 30 and facilitate the lifting of the net cage 30; the plurality of conveying belts 4011 of the feeding part 401 can store and intermittently convey the bait to the first pipeline 4021 of the feeding part 402, and the second pipeline 4022 flushes the bait in the first pipeline 4021 into the culture cavity of the net cage 30, thereby continuously supplying the bait for the culture objects.

[0042] Thus, the net cover 306 is detachably assembled on the main frame 301 of the net cage 30, so that the net cover 306 can be quickly installed or replaced, the sliding mechanism 20 provided in the passage 302 of the net cage 30 is used to make the net cage 30 smoothly ascend and descend by being sleeved on the support pile 10 and being in floating rolling contact with the support pile 10, the bait feeding part 401 is used to store a large amount of bait and deliver the bait to the bait delivery part 402 in a timed and quantitative manner, and the bait delivery part 402 is used to flush the bait delivered by the bait feeding part 401 into the net cage 30; thus, the entire lifting net cage breeding device has a simple structure, is convenient to install and replace the net cover 306, can store a large amount of bait and automatically deliver the bait in a timed and quantitative manner, and is not easily affected by the attached objects to affect the smoothness of the net cage 30.

[0043] The net cover 306 has a plurality of mesh holes, which are not shown in the figure.

[0044] The main frame 301 has a plurality of first installation slots 3011, the top of the first installation slot 3011 is open to put or take out the net cover 306 from the open part, and the open part of the first installation slot 3011 is provided with a quick release structure 305 one by one, and the quick release structure 305 is suitable for limiting the net cover 306 in the first installation slot 3011.

[0045] It can be understood that in the assembled state, the edge of the net cover 306 is quickly clamped into the first installation slot 3011 through the first installation slot 3011, and then the net cover 306 is fixed in the first installation slot 3011 by cooperating with the quick release structure 305, so as to realize the quick assembly of the net cover 306; in the disassembled state, the fixing of the net cover 306 is released by the quick release structure 305, and then the net cover 306 is separated from the first installation slot 3011, so as to realize the quick assembly and replacement of the net cover 306.

[0046] Further, the quick release structure 305 has a fixing part 3051, a quick release part 3052 and a fastening part 3053, the fixing part 3051 is provided with an assembly hole, the fixing part 3051 is rotatably arranged in the horizontal direction to shield or avoid the open part of the first installation slot 3011, the quick release part 3052 is rotatably arranged in the vertical direction to be connected or separated from the assembly hole, and the fastening part 3053 is suitable for detachably fixing the fixing part 3051 and the quick release part 3052.

[0047] It can be understood that when the net cover 306 is clamped into the first installation slot 3011, the net cover 306 is shielded in the first installation slot 3011 by rotating the fixing part 3051, then the quick release part 3052 is rotated and clamped with the fixing part 3051, and then the fixing part 3051 and the quick release part 3052 are detachably fixed by the fastener 3053, so that the net cover 306 can be quickly fixed in the first installation slot 3011, and the net cover 306 can be quickly disassembled and replaced. The fixing part 3051 has a clamping groove with one end open and is rotatably arranged on the horizontal support of the main frame 301, the quick release part 3052 can be a screw rod and is rotatably arranged on the vertical support of the main frame 301, and the fastener 3053 can be a nut, so that the clamping groove, the screw rod and the nut cooperate to quickly fix and disassemble the net cover 306.

[0048] Further, the main frame 301 includes a plurality of horizontal supports and a plurality of vertical supports, and the plurality of horizontal supports and the plurality of vertical supports form a plurality of horizontal installation surfaces 303 and a plurality of vertical installation surfaces 304. The plurality of first installation slots 3011 are distributed in a stepped manner in the vertical direction of the vertical installation surface 304.

[0049] It can be understood that the plurality of horizontal installation surfaces 303 and the plurality of vertical installation surfaces 304 formed by the plurality of horizontal supports and the plurality of vertical supports can facilitate the installation of the plurality of net covers 306, thereby wrapping the main frame 301 to form a breeding cavity. The plurality of first installation slots 3011 are distributed in a stepped manner in the vertical direction of the vertical installation surface 304, so that the net covers 306 can be installed in multiple layers in the vertical direction without interfering with each other. When assembling the net covers 306, the net covers 306 are placed in the first installation slots 3011 of each layer and then fixed by the quick release structure 305. When any layer of the net cover 306 needs to be replaced, the quick release structure 305 can be detached to directly extract the net cover 306 that needs to be replaced, thereby achieving the effect of quick assembly and replacement.

[0050] Each first installation slot 3011 is provided with a second installation slot 3012 in parallel in the front and rear horizontal direction to install the net cover 306, so that the mesh of the net cover 306 in the first installation slot 3011 and the mesh of the net cover 306 in the second installation slot 3012 are staggered and overlapped.

[0051] It can be understood that the mesh of the net cover 306 in the second installation slot 3012 and the mesh of the net cover 306 in the first installation slot 3011 are staggered and overlapped, which can slow down the effect of sea current and avoid impact on the breeding objects. The size of the mesh can be set according to the breeding objects. The net cover 306 in the first installation slot 3011 and the net cover 306 in the second installation slot 3012 arranged in parallel in the horizontal direction can be fixed by the same quick release structure 305. In addition, the net cover 306 can be provided with a handle to facilitate installation and disassembly.

[0052] For the elastic member 201, the elastic member 201 has a plurality of elastic members 201 which are connected one by one with the plurality of rolling members 202, and the plurality of elastic members 201 are distributed circumferentially at the top opening position and the bottom opening position of the channel 302.

[0053] It can be understood that when the net cage 30 is below the sea level, the net cage 30 will be shaken due to the sea current, and thus the net cage 30 will collide with the support pile 10. By distributing the plurality of elastic members 201 circumferentially at the top opening position and the bottom opening position of the channel 302, the net cage 30 as a whole is buffered and supported to keep balance, so that the collision of the net cage 30 with the support pile 10 can be reduced when the net cage 30 is shaken, thereby greatly reducing the damage of the net cage 30 and the support pile 10. During the lifting of the net cage 30, the plurality of elastic members 201 are connected one by one with the plurality of rolling members 202, so that each rolling member 202 can floatingly contact the support pile 10. When the rolling member 202 encounters the attachments on the support pile 10, the rolling member 202 can float and roll along the surface of the attachments to pass over the attachments, so that the net cage 30 can keep balance and also ensure smooth lifting. The elastic member 201 can be rubber, and the rolling member 202 can be a caster. In addition, the net cage 30 is provided with lifting lugs to connect lifting ropes. The lifting lugs on the net cage 30 are connected by the lifting ropes, so that the net cage 30 can be lifted, thereby facilitating the operation of releasing fry, collecting fish, and maintenance. The net cage 30 can be lifted by a motor cooperating with the lifting ropes. The lifting lugs can be arranged circumferentially along the net cage 30, so that the net cage 30 is uniformly stressed, thereby ensuring balanced lifting.

[0054] For the first pipeline 4021, the first pipeline 4021 is provided with a valve 4023. The valve 4023 is adapted to close the first pipeline 4021 after the first pipeline 4021 receives the bait to prevent the bait from overflowing from the feeding port of the first pipeline 4021 when being flushed.

[0055] It can be understood that when the conveyor belt 4011 delivers the bait into the first pipeline 4021, the valve 4023 is closed, so that the bait in the first pipeline 4021 below the valve 4023 can be flushed into the breeding cavity of the net cage 30 when the second pipeline 4022 is connected to seawater. The second pipeline 4022 can flush the bait by sucking seawater through a water pump. The discharge port of the first pipeline 4021 can be arranged at the middle position of the breeding cavity, so that the bait can be discharged at the middle position for the breeding objects to eat, thereby avoiding the waste caused by the bait spreading outside the net cage 30 in a short time.

[0056] For the conveyor belt 4011, the conveyor belt 4011 is provided with a plurality of partitions 4012 which are spaced apart along the conveying direction. Adjacent two partitions 4012 jointly form a storage space.

[0057] It can be understood that the conveying belt 4011 is divided into a plurality of storage spaces by arranging a plurality of partitions 4012 on the conveying belt 4011, so that the bait can be stored in the storage space, and the bait can be more accurately distributed through the storage space, so as to facilitate the control of the feeding amount of the bait and avoid insufficient or excessive feeding. The conveying belt 4011 can be provided with a stop block on both sides to prevent the bait from spilling from both sides of the conveying belt 4011.

[0058] Further, a plurality of conveying belts 4011 are arranged in the vertical direction, and the output end of each conveying belt 4011 is communicated with the feeding port of the first pipeline 4021.

[0059] It can be understood that the plurality of conveying belts 4011 are arranged in the vertical direction, so that the bait can be stored in the bait feeding part 401 and conveyed to the feeding port of the first pipeline 4021, thereby reducing the frequency of replenishing the bait, and the structure of the bait feeding part 401 is more compact, reducing the occupied space. The plurality of conveying belts 4011 can be driven by a plurality of rotating driving members 4013 connected one by one to convey the bait. Since the bait needs to be periodically fed, the rotating driving member 4013 drives the conveying belt 4011 to convey the bait one by one, which can accurately control the time when the bait needs to be conveyed, and the rotating driving member 4013 can accurately control the amount of bait that needs to be conveyed on the conveying belt 4011, thereby realizing timed and quantitative feeding, and facilitating the growth of the breeding object. The rotating driving member 4013 can be a motor cooperating with a controller, thereby realizing timed and quantitative conveying.

[0060] In addition, the bait feeding part 401 further comprises a guide member 4024 arranged near the output end of the conveying belt 4011 to guide the bait conveyed by the conveying belt 4011 into the feeding port of the first pipeline 4021.

[0061] It can be understood that since the width of the conveying belt 4011 is greater than the diameter of the first pipeline 4021, the bait conveyed by the conveying belt 4011 can be guided into the first pipeline 4021 by the guide member 4024. The guide member 4024 can be in a half-wrapped state of the plurality of conveying belts 4011 in the vertical direction, so as to avoid the bait from spilling and causing waste when entering the first pipeline 4021. A plurality of baffles 40241 can be arranged in the guide member 4024, and the plurality of baffles 40241 are arranged in the vertical direction and staggered to disperse the falling bait into the feeding port of the first pipeline 4021. Since the bait is easy to be damp and form lumps at sea, the falling bait can be broken up by colliding with the plurality of baffles 40241, so as to facilitate the smooth entry of the bait into the first pipeline 4021 without causing blockage.
