Description

Technical Field

[0001] The utility model relates to the field of marine engineering equipment, in particular to a lifting installation unit and a breeding cage containing the lifting installation unit. Background Art

[0002] In recent years, the decline of offshore fishery resources due to overfishing and environmental pollution has become a global problem. Expanding aquaculture into deepwater and deep-sea waters has become an inevitable trend, with aquaculture gradually shifting from nearshore to deep-sea areas. As an effective marine aquaculture method, aquaculture cages have been widely used and developed around the world.

[0003] At present, aquaculture cages are mainly composed of a frame system and an anchoring system. The frame system is assembled from floating bodies such as buoys, and then fixed to a certain water layer height by an anchoring system. The above-mentioned structure aquaculture cages have poor wind and wave resistance and are generally set in areas with small winds and waves. They are easily affected by natural disasters such as typhoons. The self-elevating lifting cage is an advanced aquaculture cage that can be freely raised and lowered on the water surface and underwater according to aquaculture needs and environmental conditions. The self-elevating cage includes pile legs, a frame system, and a lifting transmission device. The frame system is movably installed on the pile legs. The frame system is controlled by the lifting transmission device so that the frame system can be freely raised and lowered along the pile legs on the water surface and underwater, realizing functions such as aquaculture in specific water layers and typhoon protection.

[0004] Modular and standardized production methods will help promote the industrialization and large-scale development of deep-sea aquaculture cages. Modular and standardized product production inevitably leads to smaller modules, which in turn places higher demands on the connection components between the legs and the frame system. However, existing modular installation structures are complex, bulky, and lack a high degree of standardization. They are also difficult to transport and assemble, hindering on-site assembly and cage deployment. Utility Model Content

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. The present application provides several lifting and installation units. Due to the modular design concept, the lifting and installation units between the same type of cage bodies are universal, which improves the universality of modular cage accessories. The lifting and installation units between different types of cage bodies can be selected according to the shape of different cage bodies and the assembly structure of modular cages to meet the installation needs of various types of cages, improve the applicability of modular cage accessories, realize modular and standardized batch factory production, ensure production accuracy and facilitate transportation, and facilitate on-site assembly and cage deployment.

[0025] In addition, the types of lifting and installation units are simple, the proportion of standard parts is large, the size of parts is relatively small, and production and processing are relatively easy. The above characteristics make its manufacturing cost relatively low. Under market conditions, this reduces the breeding cost of deep-sea aquaculture cages.

[0026] 2. The annular mounting joint body is designed with a variety of panels arranged in a crisscross pattern, dividing the entire structure into multiple hollow chambers. This structure can not only meet the strength requirements of the annular mounting joint body itself, but also meet the bearing capacity and ocean current impact force required during lifting and lowering movements. At the same time, the above structure is lighter and can reduce weight while ensuring strength.

[0027] 3. This application utilizes radially distributed reinforcement plates welded to the annular mounting section, reducing the weight of the lift installation unit while increasing the structure's torsional resistance. Furthermore, lift installation units 1 through 4 described in this application all employ this structure and achieve the same technical benefits.

[0028] 4. The present application divides the inner ring panel into multiple inner ring pieces so that the lifting installation unit will not be in complete contact with the pile legs during the lifting process of the aquaculture cage. On the one hand, the friction between the inner ring of the lifting installation unit and the pile legs is reduced. On the other hand, slight deformation of the pile legs when they come into contact with the lifting installation unit is avoided. In severe cases, irreversible deformation may occur, and even the pile legs may break due to excessive force, causing accidents.

[0029] 5. This application provides multiple sliding pieces on the inner wall of the inner ring panel for direct contact with the pile legs. The multiple sliding pieces are evenly distributed on the outer wall of the pile legs, playing a role in locating the track during the lifting process of the net box body.

[0030] 6. In this application, a support seat is designed on the annular mounting section body. On the one hand, it is used to increase the strength of the transmission position where the rack and teeth are meshed on the annular mounting section body, further reducing the impact of lateral forces such as wave force and wind force on the cage during the lifting process; on the other hand, it is used as an installation structure for the rack and pinion transmission device, rationally utilizing the top surface of the lifting installation unit, and installing two sets of transmission devices at each upper lifting node, saving space and at the same time improving the transmission stability of the rack and pinion.

[0031] 7. This application incorporates pin connectors on the lifting and mounting units between adjacent aquaculture cages. These pin connectors are used to securely connect the modular aquaculture cages, allowing them to lean against and connect with each other in the ocean, improving the stability of the cages' subsea installation. When the aquaculture cages need to be raised or lowered, the pin connectors are disassembled to release the fixed connections between the cages, allowing them to be raised or lowered individually.

[0076] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0077] like Figure 1-33 As shown, the rack-and-pinion lifting aquaculture cage is an advanced aquaculture cage, specifically comprising legs 200, a cage body 300, and a rack-and-pinion transmission device 400. The rack-and-pinion transmission device controls the cage body, allowing it to freely rise and fall along the legs both on the water surface and underwater, achieving functions such as aquaculture in specific water layers and typhoon protection. To achieve modular and standardized production of aquaculture cages, this application manufactures the cage body 300 into a modular, independent cage frame body, or disassembles it into multiple standardized cage surface modules 301, which are then enclosed by multiple cage surface modules to form individual independent cage frame bodies. Two racks 202 extend outward in the axial direction on either side of the legs, and the lifting installation unit 100 is mounted on the legs. The cage body is detachably mounted on the lifting installation unit 100, and the rack-and-pinion transmission device 400 drives the lifting installation unit 100 to freely rise and fall along the legs both on the water surface and underwater.

[0078] This application designs a lifting and installation unit 100 structure, which serves as an installation node for the modular cage body, movably installing the cage body on the pile legs; at the same time, it also serves as an installation node for the rack and pinion transmission device, and the rack and pinion transmission device is installed on the lifting and installation unit, thereby driving the entire cage body to rise and fall freely on the water surface and underwater along the pile legs.

[0079] Specifically, the pile leg 200 includes a pile leg body 201 and racks 202 extending axially outward along both sides of the pile leg body. The lifting installation unit of the present application is mounted on the pile leg body, wherein the pile leg body 201 is inserted into the first cavity, and the two racks 202 are correspondingly placed in the second cavity. The net cage body is detachably mounted on the lifting installation unit 100. The rack and pinion transmission device 400 is fixedly mounted on the lifting installation unit 100 and includes at least a motor 401 and a climbing gear (not shown). The climbing gear is mounted on the power output shaft of the motor and is driven to rotate by the motor. The climbing gear engages with the rack on the pile leg to achieve lifting transmission.

[0080] In the present application, the cage body 300 is a cage-shaped space truss structure, which is specifically modularly constructed and expanded by several cage surface modules. Its cross-sectional shape can be various, such as triangular, square, sun-shaped, field-shaped, quadrangular, pentagonal, hexagonal, octagonal, etc., or it can be assembled in sequence from multiple individual "square-shaped" modular cages, such as double-mouthed, triple-mouthed, multi-mouthed, etc., or it can be assembled in sequence from multiple individual "sun-shaped" modular cages, such as four-mouthed, six-mouthed, eight-mouthed, etc. Figure 3a -h as shown.

[0081] Compared with existing modular accessories, the lifting and installation unit of the present application has multiple functions in the gear rack lifting aquaculture cage. It selects lifting and installation units with different structures according to the shape of the modular cage body and the assembly structure of the modular cage. Specifically, a variety of lifting and installation units are designed according to the number of connections with the cage surface module and the installation position. The present application provides at least the following embodiments of the lifting and installation units for selection.

[0082] The present application provides several lifting and installation units. Due to the modular design concept, the lifting and installation units between the same type of cage bodies are universal, which improves the universality of modular cage accessories. The lifting and installation units between different types of cage bodies can be selected according to the shapes of different cage bodies and the assembly structure of modular cages to meet the installation needs of various types of cages, improve the applicability of modular cage accessories, realize modular and standardized batch factory production, ensure production accuracy and facilitate transportation, and facilitate on-site assembly and cage deployment.

[0083] In addition, the types of lifting and installation units are simple, the proportion of standard parts is large, the size of parts is relatively small, and production and processing are relatively easy. The above characteristics make its manufacturing cost relatively low. Under market conditions, this reduces the breeding cost of deep-sea aquaculture cages.

[0086] Example 2 Lifting Installation Unit 2

[0087] The net box body of this application takes the shape of a square as an example to describe the use state and operation process of the lifting installation unit 2 of this embodiment. The net box body 300 of this embodiment is composed of at least four upright net box surface modules 301, such as Figure 5-17 The lifting and installation unit 2 102 of this embodiment is respectively connected to the four corners of the U-shaped cage body to fix two adjacent cage surface modules to each other. Then the lifting and installation unit is mounted on the pile legs, and the gear rack transmission device drives it to move freely up and down along the pile legs on the water surface and underwater.

[0088] Specifically, the second lifting and installation unit 102 is used to install two mesh box surface modules; the second lifting and installation unit 102 includes an annular installation section body 1, the inner ring portion of which is provided with a first cavity 2 for installing the pile legs 200, and the first cavity is provided with two second cavities 3 for installing the teeth; the two second cavities are distributed along the radial direction on both sides of the outer periphery of the first cavity;

[0089] The outer ring portion of the annular mounting section body 1 is provided with a mounting assembly 4 for mounting two mesh box surface modules; wherein the mounting assembly includes a first mounting assembly 41 and a second mounting assembly 42, the first mounting assembly mounting one of the mesh box surface modules, and the second mounting assembly mounting the other mesh box surface module;

[0090] The first installation component 41, the second installation component 42 and the two second cavities 3 are staggered and distributed on the same horizontal plane. Figure 6 shown.

[0091] Optionally, each of the mounting components 41 / 42 includes a horizontal mounting portion 41-1 / 41-2 and an inclined mounting portion 41-1 / 41-2. The first mounting component is briefly described as an example. Figure 7 As shown, the first mounting assembly includes a horizontal mounting portion 41-1 and an inclined mounting portion 41-2, wherein the horizontal mounting portion is arranged along the radial direction on the outer wall of the outer ring portion of the annular mounting section body 1, and the inclined mounting portion is arranged obliquely on the upper edge of the outer ring portion of the annular mounting section body 1 (applicable to the lifting and lowering mounting node of the upper cage body, such as Figure 7 As shown) or the lower edge (applicable to the lifting installation node of the lower cage body, such as Figure 9 As shown), different annular installation sections are selected according to the installation requirements of the cage body; the horizontal installation portion and the inclined installation portion on each of the installation components are located on the same vertical plane.

[0092] Optionally, the annular mounting section 2 includes an outer ring panel 11, an inner ring panel 12, and a horizontal panel 13; the outer ring panel is arranged upright, and the inner ring panel is concentrically arranged on the inner side of the outer ring panel; a plurality of the horizontal panels are horizontally supported between the outer ring panel and the inner ring panel; the plurality of the horizontal panels divide the annular mounting section into a plurality of hollow chambers, such as Figure 12-14 shown.

[0093] The annular mounting joint body is designed with a variety of panels arranged in a criss-cross pattern, dividing the entire structure into multiple hollow chambers. This structure can not only meet the strength requirements of the annular mounting joint body itself, but also meet the bearing capacity and ocean current impact force required during lifting and lowering movements. At the same time, the above structure is lighter and can reduce weight while ensuring strength.

[0094] Optionally, the annular mounting section further comprises a plurality of reinforcing plates 14, each of which is arranged upright, and the plurality of reinforcing plates are radially distributed between the outer ring panel and the inner ring panel, such as Figure 13 shown.

[0095] This application reduces the weight of the lifting installation node by welding radially distributed reinforcement plates within the annular installation node, while increasing the structure's torsional resistance. In addition, the lifting installation units 1 to 4 described in this application all adopt the above structure and have the same technical effect.

[0096] Optionally, the inner ring panel is divided into a plurality of inner ring pieces 12-1, each of which horizontally supports a horizontal panel. Figure 14 shown.

[0097] The present application divides the inner ring panel into multiple inner ring pieces so that the lifting and mounting unit will not be in complete contact with the pile legs during the lifting process of the aquaculture cage. On the one hand, it reduces the friction between the inner ring of the lifting and mounting unit and the pile legs. On the other hand, it avoids slight deformation when the pile legs come into contact with the lifting and mounting unit. In severe cases, there will be irreversible deformation, and even the pile legs will break due to excessive force, causing accidents.

[0098] Optionally, the inner wall of the inner ring panel is provided with a plurality of sliding sheets 15, which are evenly distributed on the inner ring panel, and the contact area between the sliding sheets and the pile legs is smaller than the contact area between the inner ring panel and the pile legs, such as Figure 14 shown.

[0099] In addition, the present application provides multiple sliding pieces on the inner wall of the inner ring panel for direct contact with the pile legs. The multiple sliding pieces are evenly distributed on the outer wall of the pile legs, playing a role in locating the track during the lifting and lowering process of the net box body.

[0100] Optionally, two support seats 16 extending from the inner ring part to the outer ring part are provided on the annular mounting joint body. A U-shaped groove 16-1 is provided on the inner side of the support seat, and the second cavity is arranged in the U-shaped groove 16-1, as Figure 14 shown.

[0101] In this application, support seats are designed on the annular mounting joint body. On the one hand, it is used to increase the strength of the meshing transmission position between the rack and the teeth on the annular mounting joint body, and further reduce the influence of lateral forces such as wave force and wind force on the cage during the lifting process. On the other hand, it is used as the installation structure of the rack and pinion transmission device, reasonably utilizing the top surface of the lifting installation unit. Two sets of transmission devices are installed at each upper lifting node, saving space and at the same time improving the transmission stability of the rack and gear.

[0102] Optionally, the annular mounting joint further设有 an eccentric pin connecting member 17, as Figure 8 shown.

[0103] In this application, an eccentric pin connecting member is designed on the lifting installation unit between two adjacent aquaculture cages for the fixed connection between each modular aquaculture cage, enabling them to rely on and connect with each other in the sea area and improving the installation stability of the cages under the sea. When the aquaculture cage needs to be lifted or lowered, the fixed connection between each aquaculture cage is released by disassembling the eccentric pin connecting member, realizing the lifting and lowering function of each aquaculture cage.
