Description

Technical Field

[0001] This utility model relates to the technical field of marine aquaculture, and in particular to a lifting aquaculture cage based on an offshore wind power jacket foundation. Background Technology

[0002] Marine cage aquaculture, as an important marine fisheries production method, has been widely used in coastal areas of my country in recent years. However, due to frequent typhoons and severe sea conditions in some sea areas, traditional cage equipment is often damaged, and cultured organisms escape, making marine cage aquaculture extremely risky. To reduce these risks, most cages can only be concentrated in harbors, nearshore waters, or areas with sheltered islands, limiting aquaculture space and hindering the further development of the industry.

[0003] The emergence of offshore wind turbine jacket foundation structures has brought new opportunities to marine cage aquaculture. This structure provides support through the jacket, and netting is added within its internal space to create the aquaculture water body. It can rely on offshore wind power platforms to achieve functions such as power support, feed storage, and feeding, effectively reducing construction and development costs and providing a new approach to marine cage aquaculture development.

[0004] Currently, some large-scale truss-type iron cages in China, relying on their strong anchoring and structural design, are beginning to expand into deeper open sea areas for aquaculture operations. However, several problems remain. Firstly, the cage structure and netting of most truss-type cages are fixed to the water surface. The movement amplitude and duration of water near the surface are the greatest among different water layers, requiring reinforced cage structures and netting to support external loads, significantly increasing construction costs. Secondly, because the cages are fixed to the water surface, violent water churning caused by severe sea conditions can easily injure or even kill the marine life cultivated inside, seriously affecting aquaculture efficiency. Furthermore, existing cage harvesting methods mostly involve netting, which is cumbersome and prone to incomplete harvesting, further hindering the development of the marine cage aquaculture industry. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a lifting aquaculture cage based on the offshore wind power jacket foundation. By coordinating the lifting and tightening of the net, it can effectively avoid the influence of water waves and direct sunlight, and reduce the structural strength requirements of the cage, thereby reducing costs. At the same time, it can ensure thorough harvesting during the fishing season without the need for netting, which greatly improves operational efficiency.

[0006] The objective of this utility model can be achieved by adopting the following technical solutions:

[0007] A lifting aquaculture cage based on an offshore wind turbine jacket foundation includes an aquaculture cage body, a jacket foundation, multiple lifting chute assemblies, a lifting drive device, multiple tensioning assemblies, a tensioning main rope, a tensioning drive device, a feed feeding system, and a feeding pipe. The aquaculture cage body is installed inside the jacket foundation via multiple lifting chute assemblies. The lifting drive device is located on the top operating platform of the jacket foundation and connected to the aquaculture cage. The lifting drive device drives the aquaculture cage body to rise and fall along the lifting chute assemblies. The multiple tensioning assemblies are evenly distributed circumferentially on the aquaculture cage. The outer periphery of the net cage body, and each tightening component, after encircling the aquaculture net cage body once, converges and connects at the top center of the aquaculture net cage body, and is connected to the lower end of the tightening main rope. The upper end of the tightening main rope extends upward and is connected to the tightening drive device. The tightening drive device is set on the top operating platform, and the tightening drive device drives the tightening main rope and tightening components to tighten the aquaculture net cage body. The feed feeding system is set on the top operating platform, and the upper end of the feeding pipe is connected to the bottom of the feed feeding system, and its lower end extends into the interior of the aquaculture net cage body.

[0008] Furthermore, the jacket structure is a multi-faceted frustum shape with a smaller top and a larger bottom, and includes multiple legs evenly arranged circumferentially and a top operating platform set on the top of the multiple legs.

[0009] Furthermore, the number of lifting chute assemblies corresponds one-to-one with the number of the pipe frame legs. Each lifting chute assembly includes a chute, two sliders, and a limiting device. The chute is located inside the pipe frame legs and runs from top to bottom along the legs. The two sliders are slidably mounted on the chute and are distributed vertically. Each slider has a hole for connecting to the aquaculture cage body. The limiting device is located at the bottom of the chute to prevent the slider from sliding downwards.

[0010] Furthermore, the aquaculture cage body includes a net covering for forming the aquaculture chamber. The net covering is generally in the shape of a multi-faceted pyramid, which is smaller at the top and larger at the bottom, and is made of a bottom net covering, a top net covering, and multiple side net coverings sewn together. A lower rope is provided at each corner of the bottom of the net covering, and an upper rope is provided at each corner of the top of the net covering. The number of the lower ropes and upper ropes are consistent with the number of lifting chute assemblies and correspond one-to-one. Each lower rope is tied to the lower slider of the corresponding lifting chute assembly, and each upper rope is tied to the upper slider of the corresponding lifting chute assembly. A net covering lifting rope is provided at each corner of the top of the net covering, and multiple net covering lifting ropes extend upward and are connected to the lifting drive device. A net covering counterweight is provided at the bottom of the net covering.

[0011] Furthermore, the tightening component includes a tightening rope and multiple rings. The multiple rings are arranged longitudinally around the aquaculture net cage body and fixed to the netting of the aquaculture net cage body. The tightening rope passes through the multiple rings, wraps around the aquaculture net cage body once, and then the two ends are connected and connected to the lower end of the tightening main rope.

[0012] Furthermore, the ring is made of stainless steel that is resistant to seawater environments.

[0013] Furthermore, the middle section of the feeding tube is tied to the tightening main rope.

[0014] Furthermore, the lifting drive device is a netting lifting winch.

[0015] Furthermore, the tightening drive device is a netting tightening winch.

[0016] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0017] 1. This utility model's aquaculture cage utilizes a lifting function to keep it submerged during operation, effectively avoiding the impact of frequent waves near the surface, reducing fatigue damage caused by wave impact, lowering the structural strength requirements of the aquaculture cage, reducing costs, and also preventing the netting from being exposed to direct sunlight, thus extending its service life. Furthermore, it avoids damage to the netting and the cultured organisms within the cage caused by extreme sea conditions.

[0018] 2. This utility model's aquaculture net cage, through the coordinated lifting and tightening of the net, ensures that its overall dimensions match the internal dimensions of the guide frame as it rises or falls along the frame, preventing the net from scratching the marine organisms attached to the frame and causing damage. Simultaneously, during harvesting, the lifting and tightening of the net gradually gathers the cultured organisms within the net cage to a harvestable density, eliminating the need for additional netting and achieving thorough harvesting. This eliminates the cumbersome operations of traditional net cage harvesting, significantly improving operational efficiency. Attached Figure Description
