Description

Technical Field

[0001] The utility model relates to the technical field of marine aquaculture, in particular to an aquaculture net cage which can be lifted and lowered and automatically rotated. Background Art

[0002] Aquaculture cages that are immersed in seawater for a long time will be attached to a large number of marine organisms. These marine organisms will cause the nets to be contaminated and hinder the circulation of water, which will deteriorate the aquaculture environment. They must be cleaned regularly. Killing marine attachments by drying the nets is an efficient and convenient way to clean the nets. In addition, the deep sea environment is harsh and complex, and extreme disasters such as typhoons pose a great threat to the safety of cages and farmed fish. Sinking the cages to avoid the wind and wave loads on the sea surface is a desirable means to improve the disaster resistance of the cages. However, the existing aquaculture cages have a single function and cannot simultaneously realize the functions of rotating the drying nets and lifting them to avoid disasters. Utility Model Content

[0003] In order to solve the problem that the existing aquaculture cages have a single function and cannot realize the functions of rotating the net for drying and lifting for disaster avoidance at the same time, the utility model further proposes an aquaculture cage which can be lifted and automatically rotated.

[0004] The technical solution adopted by the utility model to solve the above technical problems is:

[0005] A breeding net cage that can be raised and lowered and automatically rotated comprises a cylindrical net cage body, two circular guide rail assemblies, two driving assemblies, four floats and four walking trolleys. The two ends of the cylindrical net cage body are respectively equipped with a circular guide rail assembly, and two walking trolleys are symmetrically arranged on the outside of each circular guide rail assembly. The walking trolleys rotate around the circular guide rail assembly through the driving assembly, and the outsides of the walking trolleys are fixedly connected with floats.

[0006] Furthermore, the circular guide rail assembly includes two circular slide rails, and the two circular slide rails are sequentially sleeved on the ends of the cylindrical net box body along the axial direction.

[0007] Furthermore, the driving assembly includes a transmission cable and two sets of pulleys. The transmission cable is mounted on the end of the cylindrical mesh box body and is arranged between two circular slide rails. The transmission cable is connected to the middle of the bottom end of the traveling trolley. A set of pulleys is respectively provided on both sides of the bottom end of the traveling trolley. Each set of pulleys is respectively clamped in a circular slide rail and is slidably connected to the circular slide rail.

[0008] Furthermore, the circular slide rail and the transmission rope are both fixedly connected to the cylindrical net box body.

[0009] Furthermore, the aquaculture net cage that can be raised and lowered and automatically rotated also includes two sliding sleeve assemblies, which are arranged between the circular guide rail assembly and the cylindrical net box body. The sliding sleeve assembly rotates relatively around the cylindrical net box body, and the circular slide rail and the transmission rope are both fixedly connected to the outside of the sliding sleeve assembly.

[0010] Furthermore, the sliding sleeve assembly includes a sliding rigid ring, a traveling wheel and a plurality of rollers. The sliding rigid ring is sleeved on the end of the cylindrical mesh box body. A plurality of rollers are evenly distributed along the circumferential direction between the sliding rigid ring and the cylindrical mesh box body. A traveling wheel is provided between the sliding rigid ring and the cylindrical mesh box body. The traveling wheel drives the sliding rigid ring to rotate relative to the cylindrical mesh box body.

[0011] Furthermore, the travel wheels and rollers are both arranged on the cylindrical net box body.

[0012] Furthermore, a driving wheel is provided in the middle of the bottom end of the traveling trolley, and the driving wheel is meshed with the transmission cable.

[0013] Furthermore, the transmission rope is a rack or a chain, and the driving wheel is a gear or a sprocket.

[0014] Furthermore, the transmission cable includes two arc-shaped transmission bent rods, the middle part of the bottom end of each walking trolley is fixedly connected to the lower end of a transmission bent rod, the top of the sliding rigid ring is fixedly connected to a driving gear box and a driving motor, the output end of the driving motor is connected to the input end of the driving gear box, and the transmission bent rod passes through the driving gear box and meshes with the output gear of the driving gear box.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The utility model provides a breeding net box capable of lifting and automatically rotating the net, which can realize the functions of rotating the net for drying and lifting and lowering for avoiding disasters.

[0017] The floats float on the water surface, and the relative positions of the two floats on the circular guide rails determine the draft depth of the cage. When the two floats move upward at the same time, the cage sinks and the draft depth increases; when the two floats move downward at the same time, the cage rises and the draft depth decreases. Through the above actions, the cage can sink to avoid disasters and float up. In addition, the utility model also realizes the net drying function through two structures and methods:

[0018] 1. When the two floats move in the same direction and at the same speed, their relative positions on the circular guide rail remain unchanged, so that the draft height of the net cage remains unchanged, and they rotate around their centroidal axis. Through the above actions, the net cage can be rotated to achieve the self-cleaning function of the drying net.

[0019] 2. By driving the sliding rigid ring to rotate relative to the net cage, the net cage floating in the water can be rotated to achieve the self-cleaning function of the drying net. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] Specific implementation method 1: Combination Figures 1 to 7 The present embodiment is described. The aquaculture net cage which can be raised and lowered and automatically rotated comprises a cylindrical net cage body 1, two circular guide rail assemblies, two driving assemblies, four floats 2 and four walking trolleys 3. Both ends of the cylindrical net cage body 1 are respectively provided with a circular guide rail assembly, and two walking trolleys 3 are symmetrically arranged on the outer side of each circular guide rail assembly. The walking trolleys 3 are rotated around the circular guide rail assembly through the driving assembly, and the outer sides of the walking trolleys 3 are fixedly connected with floats 2.

[0028] Most of the existing aquaculture cages are equipped with independent net turning and lifting devices to realize net turning and lifting. However, most of the existing cages have the following problems:

[0029] 1. When switching the net or lifting status, it is necessary to disassemble and assemble several components, which is inconvenient in actual use, especially for components deep underwater.

[0030] 2. The lifting scheme of the net cage is: the two ends of the net cage rise and fall synchronously to achieve lifting along the hanger or column. In this process, the real-time synchronous operation accuracy of the lifting devices at both ends of the net cage is very high. If there is a slight asynchrony, it will cause the net cage to be stuck between the hanger or column, and damage the sliding track or limit measures that match the net cage. The demand for high-precision coordinated actions also tends to make the lifting mechanism control system more complex and more difficult to control, and it is very difficult to ensure long-term operational reliability.

[0031] 3. In the breeding state, the cage can be released from the rotational freedom through the bearing or rotor mechanism, and at the same time, the freedom in other directions can be fixed and pressed well to avoid movement. However, in the lifting state, the cage is suspended vertically at both ends, and the freedom in the horizontal direction is in a relaxed state without sufficient compression. The cage will sway due to the shaking of the platform, gusts of wind, and waves. When there is a slight gap between the cage and the column and hanger, it will collide with each other and cause local damage.

[0032] 4. The separately installed lifting columns or hangers not only consume a lot of steel, but also only play a role during lifting, and act as a load on the floating body in normal breeding state. This overall plan determines that the amount of steel used in the platform system is difficult to control at a low level, making the platform cost higher.

[0033] Compared with the existing cages, the aquaculture cage capable of lifting and automatically rotating the net in this embodiment realizes lifting and rotating the net through a driving mechanism, which can achieve the following beneficial effects:

[0034] 1. The lifting and switching functions do not interfere with each other, and there is no need to replace components to switch the operating status.

[0035] 2. There is no need to set up special columns or hangers for lifting. The overall structure is compact and reasonable, which makes it easier to reduce the amount of steel used and reduce the cost.

[0036] 3. The cage is always reliably connected to the main structure, and all degrees of freedom are fully constrained. During the lifting process, there will be no weakening of the constraint state in the comparison scheme. Therefore, there is no risk of collision and damage between separated components under environmental loads.

[0037] 4. The lifting and net transfer control system is simpler and more reliable. It is only necessary to control the normal actions of the two sets of drive motors to make the main structure in a corresponding deformation state to achieve the lifting and net transfer functions; and the real-time synchronization accuracy of the two sets of drive motors is not high, and a slight missynchronization at a certain moment will not cause damage or jamming of the structural components, and only subsequent adjustments are needed to compensate for the accumulated deviation.

[0038] 5. The cage can be sunk to avoid disasters.

[0039] In the prior art, the cage that can realize the functions of automatic net rotation and lifting to avoid disasters is a spherical cage structure based on a rotating arm. When a spherical cage realizes a large aquaculture water volume, it needs a larger diameter, and accordingly requires sufficient water depth. The cylindrical cage can obtain a larger water body by lengthening the cage length under a limited diameter size, and can be used in sea areas with a smaller water depth. This patented technology is particularly suitable for cylindrical cages and has better applicability.

[0040] Specific implementation method 2: Combination Figures 1 to 6To explain this embodiment, the circular guide rail assembly in this embodiment includes two circular slide rails 7, and the two circular slide rails 7 are sequentially sleeved on the ends of the cylindrical net box body 1 along the axial direction. Other components and connection methods are the same as those in the first embodiment.

[0041] Specific implementation method three: Combination Figures 1 to 6 This embodiment is described. The driving assembly of this embodiment includes a transmission cable 5 and two groups of pulleys 6. The transmission cable 5 is sleeved on the end of the cylindrical net box body 1 and is arranged between two circular slide rails 7. The transmission cable 5 is connected to the middle of the bottom end of the traveling trolley 3. A group of pulleys 6 are respectively arranged on both sides of the bottom end of the traveling trolley 3. Each group of pulleys 6 is respectively clamped in a circular slide rail 7 and slidably connected to the circular slide rail 7. Other components and connection methods are the same as those of the second specific embodiment.

[0042] Specific implementation method four: Combination Figures 1 to 6 This embodiment is described, in which the circular slide rail 7 and the transmission rope 5 are both fixedly connected to the cylindrical net box body 1. Other components and connection methods are the same as those of the third embodiment.

[0043] In this embodiment, two floats 2 are installed at each end of the cylindrical net box body 1. The floats 2 are fixed to a traveling trolley 3. The traveling trolley 3 is attached to a circular slide rail 7 on the cylindrical net box body 1 through a pulley 6 and can move freely along the circular slide rail 7.

[0044] like Figure 2 and Figure 3 As shown, the float 2 floats on the water surface, and the relative position of the two floats 2 on the circular slide rail 7 determines the draft of the cylindrical net box body 1. When the two floats 2 move upward at the same time, the cylindrical net box body 1 sinks and the draft increases; when the two floats 2 move downward at the same time, the cylindrical net box body 1 rises and the draft decreases. Through the above actions, the cylindrical net box body 1 can sink to avoid disasters and float up.

[0045] When the two floats 2 move in the same direction and at the same speed, their relative positions on the circular slide rail 7 remain unchanged, so that the draft height of the cylindrical net box body 1 remains unchanged, and rotation occurs around its centroid axis. Through the above actions, the cylindrical net box body 1 can be rotated to achieve the self-cleaning function of the drying net.

[0046] Specific implementation method five: Combination Figures 1 to 6 This embodiment is described. The aquaculture net cage capable of lifting and automatically rotating nets described in this embodiment further comprises two sliding sleeve assemblies, which are arranged between the circular guide rail assembly and the cylindrical net cage body 1.

A plurality of rollers 10 are evenly arranged along the circumferential direction between the sliding rigid ring 8 and the cylindrical net box body 1.

The running wheel 9 drives the sliding rigid ring 8 to rotate relatively around the cylindrical net box body 1. Other components and connection methods are the same as those in the fifth embodiment.

[0048] In this embodiment, a sliding rigid ring 8 is installed at each end of the cylindrical net box body 1. The sliding rigid ring 8 is sleeved on the outside of the cylindrical net box body 1 and supported on a number of rollers 10 distributed on the cylindrical net box body 1. It can rotate relatively around the axis of the cylindrical net box body 1. A walking wheel 9 is arranged between the cylindrical net box body 1 and the sliding rigid ring 8 to enable the two to rotate relatively or be locked.

[0049] Two floats 2 are installed on each sliding rigid ring 8 . The floats 2 are fixed to a traveling trolley 3 . The traveling trolley 3 is attached to a circular slide rail 7 on the cylindrical net box body 1 through a pulley 6 and can freely move along the circular slide rail 7 .

[0050] like Figure 5 and Figure 6 As shown, the float 2 floats on the water surface, and the relative position of the two floats 2 on the circular slide rail 7 determines the draft of the cylindrical net box body 1. When the two floats 2 move upward at the same time, the cylindrical net box body 1 sinks and the draft increases; when the two floats 2 move downward at the same time, the cylindrical net box body 1 rises and the draft decreases. Through the above actions, the cylindrical net box body 1 can sink to avoid disasters and float up.

[0051] By driving the sliding rigid ring 8 to rotate relative to the cylindrical net box body 1, the cylindrical net box body 1 floating in the water can be rotated to achieve the self-cleaning function of the drying net.

[0052] The traveling wheel 9 is connected with a traveling motor.
