Description

Technical Field

[0001] The invention belongs to the field of deep-sea aquaculture cages and relates to a quick installation unfolder for a large deep-sea column-stabilized aquaculture platform, and is specifically used for a net installation system of a large deep-sea aquaculture cage. Background Art

[0002] With the booming development of deep-sea aquaculture, this field is gradually becoming a new hot spot in aquaculture. Faced with vast marine resources and growing market demand, the scale of aquaculture has continued to expand, giving rise to the emergence of many large-scale aquaculture cages. These large cages are the core facilities of deep-sea aquaculture. They not only provide spacious living space for fish, but also help improve aquaculture efficiency and yield.

[0003] However, the construction and maintenance of large-scale aquaculture cages pose new challenges. Among them, the installation and replacement of nets, as an important component of the cages, is a complex and critical task. The assembly and disassembly of nets at a depth of tens of meters underwater is not only a test of technology, but also a major challenge to safety. Due to the harsh underwater environmental conditions, factors such as water flow, pressure and visibility will increase the difficulty of the operation. Workers must complete precise operations within a limited diving time, which undoubtedly increases the difficulty coefficient and danger index of manual operations. In addition, the dynamic behavior of nets in water also increases the complexity of the task. Under the action of water flow, the nets may flutter or twist, making the already complex installation process even more difficult. In this case, traditional manual operation methods may not guarantee the correct installation of the nets, and may even cause damage to the nets or affect the safety of farmed organisms.

[0004] In response to these problems, the industry is exploring more efficient and safe technical solutions, such as developing dedicated underwater robots and automated equipment to reduce the risks of manual operations and improve work efficiency and quality. At the same time, researchers are also working to improve the materials and designs of nets to make them more adaptable to the special environment of deep-sea waters, thereby simplifying the installation process and extending its service life. Through technological innovation and practical exploration, deep-sea aquaculture is expected to overcome the current challenges and achieve sustainable development. In recent years, the construction of various large-scale deep-sea aquaculture cages, Liu Weibin et al. published the "Research on the Application Technology of Biological Anti-Attachment of Deep-sea Cages and Fence Aquaculture Nets" in 2019, which mentioned that nets are an important part of deep-sea aquaculture cages and fence facilities and equipment. The installation of nets has also become an indispensable link in large-scale deep-sea aquaculture cages. The efficiency of installing nets by manpower alone is too low. If the underwater work can be completed at a convenient working surface, the work efficiency can be greatly improved. In the past, the installation of nets relied too much on human diving and installation, and there were the following specific problems:

[0005] 1. Manual work needs to be done frequently in the water to dismantle and install the nets.

[0006] 2. The net floats unsteadily under the buoyancy of water, making underwater installation more difficult.

[0007] 3. Manual launching operations are time-consuming and labor-intensive, and are accompanied by uncertain factors such as casualties.

[0008] 4. The structure is large, the size of the net is large, and the weight is heavy, which makes it time-consuming and labor-intensive to install, dismantle, and collect the net.

[0009] Therefore, developing a device that can perform part of the work of net installation on the water surface has great potential and practical application value. Summary of the invention

[0010] The purpose of the present invention is to address the deficiencies of the prior art and propose to transfer one of the traditional net installation steps to the water surface to improve the efficiency of net installation and disassembly.

[0011] The technical solution of the present invention:

[0012] A quick installation system for a net structure of a large deep-sea column-stabilized aquaculture platform, comprising a mooring machine 10, a net quick unfolder 9, a carbon fiber chain 14 and a cable maker 7;

[0013] The net quick spreader 9 is a cylindrical structure with a hollow center, and its upper surface is an arc transition surface. The hollow center is used to cooperate with the central column 5; the central column 5 is fixedly connected to the working platform 6 located above the water surface of the net box, and the net quick spreader 9 slides on the central column 5; a ball 1 is arranged at a central height and every 120 degrees along the inner surface of the net quick spreader 9, and one of the balls 1 is arranged at a position where the groove 2 is rotated 60 degrees clockwise. The ball 1 is used to reduce the friction between the net quick spreader 9 and the central column 5, so that the movement process is smooth; along the net quick spreader 9 A plurality of evenly distributed net buckles 3 are arranged at the center of the outer wall for connecting the net 13; the inner surface of the net quick spreader 9 is provided with three T-shaped grooves 2 which pass through from top to bottom, and the grooves 2 are used to prevent the net quick spreader 9 from rotating during movement and causing the net 13 to be entangled; a plurality of evenly distributed carbon fiber chain buckles 4 are arranged on the upper and lower surfaces of the net quick spreader 9, one end of the carbon fiber chain 14 is connected to the carbon fiber chain buckle 4 on the upper surface of the net quick spreader 9, and the other end is connected to the carbon fiber chain buckle 4 on the lower surface of the net quick spreader 9, forming a closed loop connection;

[0014] The mooring machine 10 and the cable maker 7 are fixed on the working platform 6, and both are controlled by the control console 8 of the mooring machine and the cable maker;

[0015] The carbon fiber chain 14 is controlled by the mooring machine 10 and the cable maker 7;

[0016] Three evenly distributed automatic fixing hooks 15 are arranged on the lower surface of the net quick spreader 9, and the automatic fixing hooks 15 are in the shape of a bent palm; the front part 25 of the automatic fixing hook is in the shape of a bendable finger, which is fixed to the net quick spreader 9 by a bolt 24; the front part 25 of the automatic fixing hook rotates inward under pressure, and at this time the hook fixing pile 16 enters the automatic fixing hook 15, and the front part 25 of the automatic fixing hook grabs the hook fixing pile 16 fixed horizontally at the bottom of the net box; when disassembly is required, the bolt 24 is removed or loosened, and the automatic fixing hook 15 can loosen the hook fixing pile 16.

[0017] The net 11 is arranged on the inner wall of the net box to fix the net 13; the traction rope 12 is installed around the net box to pull the net 13 to unfold, and the number of traction ropes is determined according to actual conditions; the guide pile 17 is a horizontal cylinder fixed at the bottom of the net box and is used to change the direction of force.

[0018] Among them, a force reduction device is provided in the cable winch 10, which consists of a primary gear 18, a secondary gear 20, a tertiary gear 19, a hinge shaft 21, and hinge teeth 22, wherein the primary gear 18 is a gear with a radius of 250 mm, the secondary gear 20 is a gear with a radius of 100 mm, and the tertiary gear 19 is a gear with a radius of 50 mm; the primary gear 18 and the tertiary gear 19 are meshed to increase the rotation speed and reduce the torque; the secondary gear 20 and the hinge shaft 21 are connected by a key, and the secondary gear 20 drives the hinge shaft 21 to rotate; the hinge shaft 21 acts on the carbon fiber chain 14 through the hinge teeth 22, thereby driving the carbon fiber chain 14 to rotate, so that the carbon fiber chain 14 is subjected to force to pull the net clothing quick unfolder 9.

[0019] The high-pressure water gun 23 is installed on the working platform 6 at a position corresponding to the place where the carbon fiber chain 14 is discharged from water, and is used to wash away the attachments on the carbon fiber chain 14 .

[0020] Each carbon fiber chain 14 is equipped with two high-pressure water guns 23 .

[0021] When the net quick spreader 9 needs to be installed, the cable winch 10 is started to allow the carbon fiber chain 14 to drag the net quick spreader 9 from the bottom of the net quick spreader 9 to the bottom of the net box. As the net quick spreader 9 descends, the traction rope 12 drags the net 13 to the inner wall of the net box and finally fixes the net 13 to the net line 11, and automatically fixes the grab hook 15 to the grab hook fixing pile 16 to complete the installation of the net 11.

[0022] When disassembling the net 11, first loosen the connection between the net 13 and the net line 11, remove the bolt 24 or loosen the bolt 24, and the automatic fixing hook 15 can loosen the hook fixing pile 16, then rotate the cable winch 10 in the opposite direction, so that the carbon fiber chain 14 pulls the net quick unfolder 9 upward to the working platform 6; finally, remove the connection between the net 13 and the net lock 3 to complete the disassembly of the net.

[0023] Beneficial effects of the present invention:

[0024] 1. The initial fixation of the net will be carried out on the water surface. The net can be installed by manually starting the mooring machine to lift the net quick unfolder to the working platform.

[0025] 2. The net is fixed on the net quick spreader. After the net quick spreader is placed in the working position by the cable winch, the automatic fixed grip is compressed and rebounds to grasp the bottom fixing pile to avoid unnecessary movement of the net installer at the bottom. After that, the net can be effectively spread out by gravity and the dragging force of the traction cable on the net, thereby further fixing the net.

[0026] 3. The installation and maintenance of deep-sea aquaculture nets have undergone revolutionary changes through the introduction of advanced underwater mechanical equipment and technology. Simply operating the machine can greatly reduce the difficulty of net installation and significantly reduce the number and time of manual underwater operations, thereby not only improving work efficiency but also greatly reducing operational risks. Operating the machine to install and maintain nets is an important step for the deep-sea aquaculture industry to move towards modernization and intelligence.

[0027] 4. During the process of collecting the net, the net shrinks, which reduces the internal space of the net and plays a role in catching fish at the same time. It reduces the installation and disassembly costs and improves the installation and disassembly efficiency. If it has the function of catching fish at the same time, large-scale breeding platforms do not need to float up and down, which greatly reduces the design and operation costs.

[0028] 5. In the installation and maintenance of nets for modern deep-sea aquaculture, the mooring machine plays a vital role. In order to improve operating efficiency, reduce energy consumption and ensure the safety and reliability of operation, an advanced force reduction device is specially installed in the mooring machine. This innovative design not only significantly reduces the power consumption of the mooring machine by cleverly utilizing the interaction between gears and teeth of different radii, but also greatly improves the speed of net installation and lifting.

DETAILED DESCRIPTION

[0037] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and technical solutions.

[0038] like Figure 1 As shown, the net quick spreader 9 is a cylindrical structure with a hollow center, and its upper surface is an arc transition surface; a ball 1 is arranged at a center height and every 120 degrees along the inner surface of the net quick spreader 9, and one of the balls 1 is arranged at a position where the groove is rotated 60 degrees clockwise; a plurality of evenly distributed net buckles 3 are arranged at the center position around the outer wall of the net quick spreader 9; three evenly distributed carbon fiber chain buckles 4 are respectively arranged on the upper surface and the lower surface of the net quick spreader 9; an automatic fixing hook 15 is arranged every 120 degrees on the lower surface of the net quick spreader 9; and three T-shaped grooves 2 are arranged on the inner circle of the net quick spreader 9.

[0039] like Figure 2As shown, when the net 13 is installed, the carbon fiber chain 14 and the carbon fiber chain buckle 4 are first connected, and then the net quick deployer 9 is dragged to the working platform 6 above the water surface by the winch 10, and the rising speed is about 1m / s. When it rises to a certain height, the cable maker 6 is used to brake. On the working platform 6, the inner edge of the net 13 is installed on the net buckle 3 on the outer edge of the net quick deployer 9, and then the net quick deployer 9 is released to the underwater working place by the winch 10. The net quick deployer 9 drags the net 13 underwater and unfolds naturally, and then the outer edge of the net 13 is towed by the traction rope 12 to connect to the surrounding net 11. When the carbon fiber chain 14 is in operation, the high-pressure water gun 23 will continuously spray high-pressure water to wash the marine attachments on it, so as to prevent excessive marine attachments from affecting the normal operation of the entire device.

[0040] like Figure 3 As shown in Figure (a), when the net quick spreader 9 is installed, the carbon fiber chain 14 drags the net quick spreader 9 to the bottom of the net box; as the net quick spreader 9 descends, the traction rope 12 drags the net 13 to the inner wall of the net box; finally, the net 13 is fixed to the net line 11 to complete the installation of the net 13. As shown in Figure (b), when disassembling, the connection between the net 13 and the surrounding net line 11 is first disassembled, and then the net quick spreader 9 is dragged to the working platform 6 by the cable winch 10 for final disassembly. Therefore, the point of improving efficiency of the present invention lies in the installation and disassembly of the inner edge of the net, and providing a fishing function.

[0041] like Figure 4 As shown, the equipment on the net box is powered by wind turbines, that is, the power supply system in the figure; the net quick unfolder 9 on the net box is controlled by a control terminal, wherein the net quick unfolder 9 is monitored in real time by the net unfolder monitor to observe its working condition, and a speed monitor is installed on it to detect whether its working speed is normal; a tension sensor is also installed on the carbon fiber chain 14 to detect whether the whole system is stuck during operation; the lifting and lowering of the net quick unfolder 9 and the control of the brake are controlled by remote control; when a problem occurs in the machine during the above work, an alarm indication will be issued to remind the staff, and at the same time the staff should immediately press the emergency brake button to stop the whole system from running, and the system can be restarted when the problem is eliminated; the display can display the net unfolder monitoring screen, as well as the speed monitor and tension sensor data.

[0042] like Figure 5 As shown, in order to reduce the power of the mooring machine, the Figure 5The force reduction device shown is transmitted through three-stage gears with different radii, which improves work efficiency while reducing power. In this way, a small-volume and low-power cable winch can be used, which saves space for the working platform and also saves electricity. The first-stage gear 18 is a gear with a radius of 250 mm, the second-stage gear 20 is a gear with a radius of 100 mm, and the third-stage gear 19 is a gear with a radius of 50 mm. The hinge teeth 22 act on the carbon fiber chain 14 through the hinge shaft 21 to rotate it.

[0043] Figure 6 As shown, when the net quick spreader 9 moves to the bottom of the net box, the grab hook 15 is automatically fixed to tighten the grab hook fixing pile 16 to fix the net quick spreader 9; the carbon fiber chain 14 is turned through the bottom guide pile 17 to connect to the lower surface of the net quick spreader 9 to achieve a closed loop, which is used to provide a downward drag force when the net quick spreader 9 is installed to the bottom of the net box.

[0044] Figure 7 As shown in FIG. (a), the front portion 25 of the automatic fixing hook is in the shape of a bendable finger, which is fixed to the net quick unfolder 9 by a bolt 24; the front portion 25 of the automatic fixing hook rotates inwards under pressure, as shown in FIG. (b), the hook fixing pile 16 enters the interior of the automatic fixing hook 15, and the front portion 25 of the automatic fixing hook grabs the hook fixing pile 16 fixed horizontally at the bottom of the net box; when disassembly is required, the bolt 24 is removed or loosened, and the automatic fixing hook 15 can loosen the hook fixing pile 16.
