Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy connecting rod trimming technology, specifically to an air flotation auxiliary device for offshore installation of aquaculture cages. Background Technology

[0002] In recent years, the deep-sea aquaculture industry has developed rapidly, and the large-scale application of large-scale aquaculture cages has become the mainstream trend in the industry. To meet the needs of high-density aquaculture, the current mainstream cage structure generally adopts a quadrilateral column frame design (typical size 46m×46m×56m), with an enclosed water volume of no less than 65,000 cubic meters and an effective aquaculture water volume of over 55,000 cubic meters. The overall structure of such cages typically weighs over 3,800 tons, classifying them as ultra-large offshore facilities.

[0003] In the existing technology, the installation and transfer of such net cages at sea mainly rely on the following operation process: First, the net cages are lifted to the deck of a semi-submersible transport vessel by a shore-based heavy crane or an offshore crane vessel. Then, the semi-submersible vessel carries the net cages to the target sea area. Finally, the crane vessel lifts the net cages from the semi-submersible vessel into the sea in the target sea area.

[0004] However, this method of transportation has significant drawbacks:

[0005] Because heavy-duty crane vessels are required for the installation of net cages into the sea, the equipment rental costs are high. At the same time, the sea lifting process is affected by the complex marine environment of wind and waves, which can easily cause problems such as the swaying of the net cage structure and sudden changes in the stress on the slings, leading to the risk of uncontrolled lifting, structural collisions, or even overturning, which poses a serious threat to operational safety. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an air flotation auxiliary device for the offshore installation of aquaculture cages, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A flotation auxiliary device for offshore installation of aquaculture cages includes a base, a cage mounted on the center of the top surface of the base, a bridge assembly mounted on the top surface of the cage, and buoyancy components mounted on the top surface of the base and around the cage, with a total of 8 sets of buoyancy components. Each buoyancy component includes a fixing plate, which is fixedly connected to the top surface of the base. An interception frame is fixedly fixed to the top surface of the fixing plate, and arc-shaped limiting plates are fixedly connected at equal intervals inside the interception frame. A U-shaped insert is slidably connected to one end of the interception frame, and a reset damping rod is fixedly connected to one side of the U-shaped insert and between the top surfaces of the interception frame. A T-shaped groove is symmetrically provided on the top surface of the fixing plate, and a storage component is slidably connected inside the T-shaped groove. An airbag component is placed above the storage component.

[0009] Furthermore, the storage component includes a pull-out plate, the top surface of the fixed plate is equipped with the pull-out plate, the bottom surface of the pull-out plate is symmetrically and fixedly connected with a T-shaped rod, the T-shaped rod slides in a T-shaped groove, and an arc-shaped placement plate is fixedly connected at equal intervals in the middle of the top surface of the pull-out plate.

[0010] Furthermore, the storage component also includes a U-shaped interceptor plate and a front interceptor plate. The top two ends of the pull-out plate are respectively fixedly connected to the U-shaped interceptor plate and the front interceptor plate. The top surface of the front interceptor plate is symmetrically provided with locking holes, and one end of the U-shaped insert rod is inserted into the locking hole.

[0011] Furthermore, the airbag component includes a cylindrical airbag, one end of which is connected to an air tube, and one end of which is connected to a one-way valve.

[0012] Furthermore, the base includes a mouth-shaped plate, a mouth-shaped reinforcing plate is fixedly connected to the center of the mouth-shaped plate, and support legs are fixedly connected to the four sides of the bottom surface of the mouth-shaped plate.

[0013] Furthermore, the cable tray assembly includes guardrail channels, with guardrail channels fixedly connected to both ends of the top surface of the cage, and a guardrail suspension bridge fixedly connected between the two sets of guardrail channels.

[0014] This utility model provides an air flotation auxiliary device for the offshore installation of aquaculture cages. Compared with the prior art, it has the following advantages:

[0015] 1. Through the cooperation of the interception frame, pull-out plate and columnar airbag in the 8 sets of buoyancy components, the base, net cage and bridge components are floated on the water surface, which facilitates the loading of the semi-submersible vessel. After transporting them to the designated location, the gas inside the columnar airbag is released so that the base and net cage sink into the sea for subsequent aquaculture.

[0016] 2. By cooperating with the interception frame, U-shaped insert, arc-shaped limiting plate, pull-out plate, arc-shaped placement plate, front interception plate and U-shaped interception plate, the columnar airbag can be fixed in the interception frame;

[0017] 3. By pulling the U-shaped insert rod, the U-shaped insert rod is disengaged from the locking hole. After disengagement, the pull plate is pulled, causing the T-shaped rod to slide in the T-shaped groove, thereby allowing the pull plate to detach from the interception frame. This makes it convenient for later staff to place or remove the columnar airbag on the pull plate. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0031] Example

[0032] To address the technical problems in the background section, the following air flotation auxiliary device for offshore installation of aquaculture cages is provided:

[0033] Combination Figures 1-6 As shown, the air flotation auxiliary device for offshore installation of aquaculture cages provided by this utility model includes a base 100, a cage 200 installed in the center of the top surface of the base 100, a bridge assembly 300 installed on the top surface of the cage 200, and buoyancy components 400 installed on the top surface of the base 100 and around the cage 200, with a total of 8 sets of buoyancy components 400; each buoyancy component 400 includes a fixing plate 401, and the fixing plate 401 is fixedly connected to the top surface of the base 100. An interception frame 402 is fixed on the top surface of the fixed plate 401. An arc-shaped limiting plate 403 is fixedly connected at equal intervals inside the interception frame 402. A U-shaped insert rod 404 is slidably connected inside one end of the interception frame 402. A reset damping rod 405 is fixedly connected on one side of the U-shaped insert rod 404 and between the top surfaces of the interception frame 402. A T-shaped groove 406 is symmetrically provided on the top surface of the fixed plate 401. A storage component is slidably connected inside the T-shaped groove 406. An airbag component is placed above the storage component.

[0034] By pulling the U-shaped insert 404, the U-shaped insert 404 is no longer connected to the storage component, making it convenient for staff to remove the storage component from the interception frame so that it can be removed or inserted into the cylindrical airbag.

[0035] In this embodiment, the storage component includes a pull-out plate 407. The pull-out plate 407 is installed on the top surface of the fixed plate 401. A T-shaped rod 408 is symmetrically and fixedly connected to the bottom surface of the pull-out plate 407. The T-shaped rod 408 slides in the T-shaped groove 406. An arc-shaped placement plate 409 is fixedly connected at equal intervals in the middle of the top surface of the pull-out plate 407.

[0036] The pull-out plate 407 facilitates the placement of the cylindrical airbag into or from the interception frame 402. At the same time, the cooperation between the arc-shaped placement plate 409 and the arc-shaped limiting plate 403 limits the cylindrical airbag, ensuring that it is fixed within the interception frame 402.

[0037] In this embodiment, the storage component also includes a U-shaped interceptor plate 410 and a front interceptor plate 411. The top two ends of the pull-out plate 407 are respectively fixedly connected to the U-shaped interceptor plate 410 and the front interceptor plate 411. The top surface of the front interceptor plate 411 is symmetrically provided with a locking hole 412. One end of the U-shaped insert rod 404 is inserted into the locking hole 412.

[0038] The U-shaped interceptor plate 410 and the front interceptor plate 411 enable positioning of both ends of the cylindrical airbag 413 and also allow for limiting and fixing of the cylindrical airbag in the later stages.

[0039] In this embodiment, the airbag component includes a cylindrical airbag 413, one end of which is connected to an air tube 414, and one end of the air tube 414 is connected to a one-way valve 415.

[0040] The device is buoyed by eight sets of suitable cylindrical airbags 413, which enable the device to float on the sea surface and facilitate subsequent transportation.

[0041] In this embodiment, the base 100 includes a mouth-shaped plate 101, a mouth-shaped reinforcing plate 102 is fixedly connected to the middle of the mouth-shaped plate 101, and support legs 103 are fixedly connected to the four sides of the bottom surface of the mouth-shaped plate 101.

[0042] The support stability of the cage 200 is increased by the mouth-shaped plate 101, mouth-shaped reinforcing plate 102 and support leg 103 in the base 100.

[0043] In this embodiment, the cable tray assembly 300 includes guardrail channels 301. Guardrail channels 301 are fixedly connected to both ends of the top surface of the cage 200, and a guardrail suspension bridge 302 is fixedly connected between the two sets of guardrail channels 301.

[0044] The guardrail passage 301 and guardrail suspension bridge 302 facilitate the movement of later-stage caretakers on the upper level to observe the feeding situation inside the net cage 200.

[0045] Working principle and usage process of this utility model:

[0046] In use:

[0047] The first step is to calculate the tonnage required for buoyancy assistance and select a suitable columnar airbag. For columnar airbag 413, an inflatable high-pressure rubber airbag is selected. The lifting weight of the crane plus the buoyancy assistance is greater than the weight of the lifted object (base, cage, cable tray assembly and buoyancy assembly).

[0048] The second step is to install the cylindrical airbag. During installation, first install the intercepting frame and pull-out plate that match the cylindrical airbag. After installation, the operator pulls the U-shaped insert rod 404. As the U-shaped insert rod 404 moves upward, it stretches and resets the damping rod 405. Simultaneously, one end of the U-shaped insert rod 404 disengages from the locking hole 412. After disengagement, the operator pulls the pull-out plate 407, causing the pull-out plate 407 to move the arc-shaped placement plate 409, the U-shaped intercepting plate 410, and the front intercepting plate 411 to one side. When the T-shaped rod 408 slides within the T-shaped groove 406, the entire storage component is pulled out from one end of the intercepting frame 402. After extraction, the operator places the airbag onto the arc-shaped placement plate 409. Simultaneously, both ends of the cylindrical airbag 413 are respectively secured by the U-shaped intercepting plate 410. The front interceptor plate 411 is positioned and blocked. After the columnar airbag 413 is placed, the storage component is pushed so that it slides the columnar airbag 413 into the interceptor frame 402. At this time, the columnar airbag will be limited and fixed in the interceptor frame 402 by the arc-shaped limiting plate 403 and the arc-shaped placement plate 409. After the limit is fixed, the U-shaped insert rod 404 is released. The U-shaped insert rod 404 will be re-inserted into the locking hole 412 by the reset damping rod 405 and the storage component will be locked and fixed in the interceptor frame 402. After fixing, the air tube 414 and the columnar airbag 413 are inflated through the one-way valve 415 so that the columnar airbag 413 is full of gas. After the 8 sets of buoyancy components 400 are fixed, the entire device can be moved to the sea surface and float on the sea surface.

[0049] The third step is to use a semi-submersible vessel to descend to a specified depth, and then use the crane on the semi-submersible vessel to stabilize the bridge frame assembly. At the same time, the cage 200 is also stabilized. After stabilization, the crane is used to move it to the semi-submersible vessel. At this point, the semi-submersible vessel rises to the surface and begins to transport the device.

[0050] The fourth step is to transport the equipment to the designated location. The semi-submersible vessel will then sink to a certain depth. The columnar airbags will provide buoyancy to the entire device. After the semi-submersible vessel sinks to the designated depth, the crane will lift the hook to stabilize the net cage. After the semi-submersible vessel leaves, the net cage will be lowered to the designated location.

[0051] Fifth, after the cage is placed in the designated position, open the one-way box 415 to allow the gas inside the columnar airbag to be released. After the gas is released, the columnar airbag is removed. To remove the columnar airbag, first pull the U-shaped insert 404 so that one end of the U-shaped insert 404 comes out of the locking hole 412. After it comes out, pull out the storage component and you can remove the columnar airbag from the storage component. Then, insert the storage component into the interception frame 402 for later use.
