Description

Technical Field

[0001] The invention relates to the technical field of oyster culture, in particular to a bidirectional rotary anti-winding culture cage lifting mechanism for oyster float hanging culture. Background Art

[0002] Oyster float culture is an efficient seawater aquaculture method that utilizes the buoyancy of the float to suspend oysters in a suitable water layer in the seawater to ensure the growth environment and feeding conditions of the oysters. It is an efficient and economical aquaculture method that is widely used in coastal areas and provides convenience for large-scale oyster aquaculture.

[0003] In actual application, the breeding cages are suspended at the bottom of the buoys by cables, and multiple groups of buoys and breeding cages are arranged on each group of cables, which is convenient for management and collection. At the same time, the depth of the water in which the breeding cages are located can be adjusted by pulling the cables. During the adjustment process, the cables on one side of the breeding cages will be tightened or loosened. When tightening, the cables on the other side of the breeding cages will be in a relaxed state. When the tightening height is large and the breeding cages rotate due to the impact of the water flow, the relaxed cables on one side of the breeding cages will be entangled with the breeding cages, and apply a certain pressure to the oysters in the breeding cages, affecting the normal growth of the oysters.

[0004] Furthermore, when the oysters are collected and the culture cages are suspended by cables, the cables on both sides of the culture cages have inconsistent tightness, resulting in excessive reeling load when the cables become entangled, which can easily cause the cables to break in severe cases.

DETAILED DESCRIPTION

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0047] See also Figures 1 to 10 In an embodiment of the present invention, a bidirectional rotary anti-entanglement culture cage lifting mechanism for oyster float hanging culture includes: a hollow float 2, a support arm group, a traction cable 16, a hook plate 15 and a follower mechanism.

[0048] A breeding cage 1 is hung on the hollow floating ball 2;

[0049] The support arm group is connected to the hollow float 2, and an elastic clamping structure is provided on the support arm group. The support arm group includes a first arm 3 and a second arm 4 symmetrically arranged, and the first arm 3 and the second arm 4 are arranged in an "eight" shape. When the traction cable 16 is connected to the first arm 3 and the second arm 4 respectively (the middle part is connected to the breeding cage 1), due to the special structure of the "eight" shape, the first arm 3 and the second arm 4 will naturally produce a tendency to unfold the traction cable 16. This tendency plays a vital role in the actual underwater environment. The water flow below the water surface is complex and changeable. The irregular direction and speed of the water flow can easily exert a force on the breeding cage 1, causing the breeding cage 1 to rotate. Through this "eight" shape arrangement, the traction cables 16 on both sides of the breeding cage 1 can be in a taut state, which can effectively reduce the probability of the water flow acting on the breeding cage 1 and causing it to rotate, and at the same time avoid the entanglement of the traction cable 16 caused by the rotation of the breeding cage 1.

[0050] The elastic clamping structure is arranged at one end of the first arm 3 away from the hollow float 2, and the end of the second arm 4 away from the hollow float 2 is in contact with two locking members 1601 arranged on the traction cable 16, and the two locking members 1601 are respectively in contact with the left and right sides of one end of the second arm 4. In the breeding system involved in the present application, there are actually multiple hollow floats 2 and corresponding breeding cages 1, and there is a one-to-one correspondence between them. In this embodiment, it should be clear that multiple groups of locking assemblies are configured in an equidistant manner on the traction cable 16, and each group of locking assemblies contains two locking members 1601. The design purpose of these two locking members 1601 is to be able to achieve precise contact with the end of the second arm 4 on each group of hollow floats 2. Through the setting, the hollow floats 2 can present a stable state of equidistant distribution on the traction cable 16.

[0051] This equidistant layout is extremely important. In actual aquaculture, if the spacing between two adjacent hollow buoys 2 and cages 1 is too small, it is easy for the two cages 1 to collide due to the impact of water flow or external forces. This collision not only damages the structure of the cages 1 but, more importantly, affects the normal growth of the oysters and may even cause damage or death. By adopting the above-mentioned equidistant layout design, this situation can be effectively avoided, thereby providing a relatively stable and safe growth environment for the oysters.

[0052] Furthermore, this design improves the utilization of aquaculture space to a certain extent. The equidistant distribution of the hollow buoys 2 and the aquaculture cages 1 makes the overall aquaculture system more rational and compact within the water body, helping to increase the number of aquacultured oysters per unit water volume and thus improving the overall efficiency of the aquaculture. Furthermore, the equidistant distribution of the hollow buoys 2 ensures uniform water flow within the aquaculture area, helping the oysters obtain sufficient oxygen and food resources, further promoting their growth and development.

[0053] See also Figures 4 and 5 The traction cable 16 is connected to the breeding cage 1, one end of the traction cable 16 is fixed to the support arm group, and the other end passes through the elastic clamping structure, the elastic clamping structure includes a mounting portion 302 provided on the first support arm 3, and a first abutting wheel 5 connected to the follower mechanism is rotatably mounted in the mounting portion 302;

[0054] The elastic clamping structure further includes an energy storage kit slidably mounted in the mounting portion 302 , and the energy storage kit is used to drive the second abutment wheel 6 connected thereto to move toward the first abutment wheel 5 ;

[0055] A plurality of groups of resistance-increasing portions are equidistantly arranged on the circumferential surfaces of the first abutting wheel 5 and the second abutting wheel 6 .

[0056] In practice, if the depth of the culture cage 1 in the water needs to be adjusted, or if the culture cage 1 needs to be hoisted for oyster collection, traction is simply applied to one end of the traction cable 16. This pulls the traction cable 16 on one side of the culture cage 1 upward, while the traction cable 16 on the other side relaxes accordingly. The follower mechanism effectively tightens the slack traction cable 16 on the other side of the culture cage 1. This ensures that the traction cables 16 on both sides of the culture cage 1 maintain consistent tension, maintaining a balanced traction process. This not only avoids the situation where the traction cable 16 on one side is too long and is wound around the breeding cage 1 when the breeding cage 1 rotates, thereby preventing unnecessary pressure on the oysters in the breeding cage 1 and ensuring their normal growth. When the traction cable 16 on one side of the breeding cage 1 is subjected to tension, the traction cable 16 on the other side of the breeding cage 1 moves upward under the action of the follow-up mechanism to keep the traction cable 16 in a tensioned state. The entire current breeding cage 1 will follow the hollow float 2 to move laterally relative to the previous position of the current breeding cage 1, so that the traction cable 16 on the next breeding cage 1 is pulled. After the adjustment is completed, if there is a deviation in the water entry depth of the breeding cage 1, at this time, due to the inconsistent depth of the breeding cage 1 in the water, the buoyancy it receives is also inconsistent. With the action of the gravity of the breeding cage 1, the depth of each breeding cage 1 also automatically changes, and finally remains at a relatively constant water depth.

[0057] Based on the above working principle, firstly, it can accurately keep the traction cables 16 on both sides of the culture cage 1 at the same tightness during the traction of the traction cables 16, thereby achieving balanced traction of the culture cage 1. This not only effectively prevents the traction cables 16 from winding up, and avoids the problem of excessive traction load caused by the entanglement of the traction cables 16, but also reduces the increase in friction caused by the entanglement of the traction cables 16, thereby reducing the risk of excessive wear of the traction cables 16 during traction; secondly, by preventing the slack traction cables 16 on one side of the culture cage 1 from being too long, it prevents the slack cables from winding around the culture cage 1 when the culture cage 1 rotates, thereby preventing the oysters from being compressed, thereby ensuring a normal growth environment for the oysters. In addition, this balanced traction mechanism also improves the stability and reliability of the entire culture system, extends the service life of the traction cables 16, reduces the cost and frequency of equipment maintenance, and provides more favorable conditions for the healthy growth of oysters.

[0058] The energy storage kit includes a connecting frame 7 slidably mounted in the mounting portion 302 and rotatably connected to the second abutting wheel 6 , with protrusions 8 provided on both sides of the connecting frame 7 slidably connected to a connecting groove 303 provided on a side of the mounting portion 302 ;

[0059] The energy storage kit also includes a telescopic shaft 10 connected to the connecting frame 7 and passing through the mounting portion 302 , and a cylindrical spring 9 is sleeved on the telescopic shaft 10 , one end of the cylindrical spring 9 is connected to the connecting frame 7 , and the other end is connected to the inner wall of the mounting portion 302 .

[0060] In this embodiment, the cylindrical spring 9 is in a compressed state in the initial state, which makes the cylindrical spring 9 have a tendency to push the connecting frame 7 and the second abutment wheel 6 toward the first abutment wheel 5. When the traction cable 16 is placed between the first abutment wheel 5 and the second abutment wheel 6, the pre-tightening force of the cylindrical spring 9 can ensure that the traction cable 16 is firmly pressed. When one end of the traction cable 16 is pulled, the pressing force can cause the first abutment wheel 5 to rotate, thereby driving the follower mechanism to move.

[0061] Through this arrangement, firstly, the pre-tightening force of the cylindrical spring 9 ensures that the traction cable 16 can maintain a stable contact force when being pulled, thereby improving the reliability and stability of the traction process; secondly, through this pre-tightening mechanism, the relaxation phenomenon of the traction cable 16 when under force can be effectively reduced, so that the follow-up mechanism can respond to the traction action more quickly and accurately, thereby improving the response speed and control accuracy of the entire system.

[0062] Furthermore, since the first abutment wheel 5 and the second abutment wheel 6 are provided with a resistance increasing portion, the friction between the traction cable 16 and the first abutment wheel 5 and the second abutment wheel 6 can be effectively increased, thereby further ensuring that the first abutment wheel 5 and the second abutment wheel 6 can rotate when one end of the traction cable 16 is pulled.

[0063] See also Figures 2 and 3 、 Figures 6 to 8 , the hook plate 15 is provided on the support arm assembly, and the hook plate 15 is connected to an end of the traction cable 16 away from the elastic clamping structure;

[0064] The following mechanism is provided on the support arm group and is connected to the elastic clamping structure. When one end of the traction cable 16 is pulled, the following mechanism can drive the hook plate 15 to move upward, thereby maintaining the same tightness of the traction cables 16 on both sides of the breeding cage 1;

[0065] The following mechanism includes two sets of connecting wheels mounted on the first supporting arm 3, a connecting belt 11 is sleeved between the two sets of connecting wheels, and one set of the connecting wheels is connected to the first abutting wheel 5;

[0066] The follower mechanism further includes a telescopic arm group fixedly connected to the connecting belt 11, a second slider 1401 being provided at the end of the telescopic arm group, the second slider 1401 being slidably connected to a second guide groove 401 provided along the length direction of the second support arm 4, the telescopic arm group including a transverse arm 13 fixedly connected to the connecting belt 11, a first slider 12 being provided on the transverse arm 13, the first slider 12 being slidably connected to a first guide groove 301 provided along the length direction of the first support arm 3;

[0067] The following arm 14 is slidably mounted on the transverse arm 13, that is, the two are slidably connected, and the following arm 14 is connected to the hook plate 15 and the second slider 1401, wherein the first slider 12 and the first guide groove 301 can make the transverse arm 13 and the first support arm 3 form a first predetermined angle, and under the cooperation of the first slider 12 and the first guide groove 301, the transverse arm 13 can move relative to the first support arm 3 at the first predetermined angle, and at the same time, the second slider 1401 and the second guide groove 401 can make the following arm 14 and the second support arm 4 form a second predetermined angle. Predetermined angle, and under the cooperation of the second slider 1401 and the second guide groove 401, the follower arm 14 can move relative to the second support arm 4 at the second predetermined angle, and based on the above arrangement, when the connecting belt 11 drives the transverse arm 13 to move relative to the first support arm 3 at the first predetermined angle, the follower arm 14 can follow the transverse arm 13 to move synchronously relative to the second support arm 4 at the second predetermined angle, and the following arm 14 will not be twisted and bent relative to the transverse arm 13 toward the breeding cage 1 due to the pulling force of the traction cable 16 on the hook plate 15.

[0068] In actual use, when one end of the traction cable 16 is pulled, the first abutment wheel 5 will rotate, and the connecting belt 11 connected thereto will move accordingly, driving the transverse arm 13 to move along the length direction of the first guide groove 301 parallel to the connecting belt 11. During the movement of the transverse arm 13, the follower arm 14 slidingly connected thereto is driven synchronously. With the precise cooperation between the second slider 1401 and the second guide groove 401, the end of the follower arm 14 away from the transverse arm 13 moves along the length direction of the second support arm 4. This series of linkages ensures that the hook plate 15 can move parallel to the second support arm 4, thereby dragging the end of the traction cable 16 away from the pulling direction upward, which effectively tightens the slack traction cable 16 on one side of the breeding cage 1 to a certain extent, ensuring the consistency of the tightness of the traction cables 16 on both sides of the breeding cage 1.

[0069] This design has significant advantages and effects in practical applications. First, through the above-mentioned mechanical linkage mechanism, the traction cable 16 can be automatically tensioned to maintain the consistency of its tightness, thereby avoiding entanglement during the traction process. This not only improves the stability and reliability of the traction process, but also reduces the risk of additional wear and damage caused by the entanglement of the traction cable 16, and extends the service life of the traction cable 16; secondly, this automatic tensioning mechanism can effectively prevent the shaking or instability of the breeding cage 1 due to the relaxation of the traction cable 16, providing a more stable growth environment for oysters, which is conducive to their healthy growth.

[0070] See also Figures 9 and 10 The bidirectional rotary anti-entanglement culture cage lifting mechanism for oyster float culture also includes: a connecting plate 17, a transverse traction component and a support component.

[0071] The connecting plate 17 is provided with a winch 18 for winding up the traction cable 16;

[0072] The transverse traction assembly is provided on the connecting plate 17 and is connected to the rotating shaft of the hoist 18. The transverse traction assembly can cause the traction cable 16 to be spirally wound around the hoist 18 at equal intervals when the hoist 18 reels the traction cable 16.

[0073] The transverse traction assembly includes a threaded rod 20 rotatably mounted on the connecting plate 17, the threaded rod 20 being connected to the rotating shaft of the hoist 18 via a belt 19, and a threaded sleeve 21 threadedly connected thereto being provided on the threaded rod 20, and two sets of sheaves 22 being provided on the threaded sleeve 21;

[0074] Guide portions 2101 are formed on both sides of the threaded sleeve 21 , and the guide portions 2101 are slidably connected to the guide members 23 provided on the connecting plate 17 .

[0075] In this embodiment, the winding and unwinding of the traction cable 16 is primarily achieved through the bidirectional rotation of the hoist 18. During this process, the rotating shaft of the hoist 18 drives the threaded rod 20 to rotate, thereby causing the threaded sleeve 21 threadedly connected to the threaded rod 20 to move along the length of the threaded rod 20. This movement not only causes the towed end of the traction cable 16 to move along the length of the hoist 18, but also allows the traction cable 16 to be spirally wound around the hoist 18 at equal intervals as the hoist 18 rotates.

[0076] This design ensures the uniformity of winding the traction cable 16 on the winch 18, and avoids the irregular accumulation of the traction cable 16 on the winch 18. In extreme cases, the irregular accumulation may cause the traction cable 16 to collapse, and then cause instantaneous release, posing a threat to the safety of operators and equipment. Therefore, this device significantly improves the stability and safety of the traction cable 16 during the process.

[0077] The support assembly is provided on the connecting plate 17 and is used to lift the traction cable 16 upwards;

[0078] The support assembly includes a hinge 26 fixedly mounted on the link plate 17, a lifting arm 24 is rotatably mounted on the hinge 26, and one end of the lifting arm 24 away from the hinge 26 is slidably connected to the traction cable 16;

[0079] The electric telescopic rod 25 connected to the hinge 26 is connected to the lifting arm 24 .

[0080] When the culture cage 1 is lifted for the purpose of collecting oysters, the electric telescopic rod 25 is first controlled to move. At this time, the action end of the electric telescopic rod 25 extends outward, and the lifting arm 24 can be deflected and lifted upward. At this time, the end of the lifting arm 24 away from the hinge 26 can lift the traction cable 16 upward, so that after the collection boat moves to the predetermined position, it can directly act on the lifted traction cable 16 to lift the culture cage 1 attached to the traction cable 16, thereby simplifying the operation process during the oyster collection process.

[0081] It should be noted that when oysters need to be collected, the breeding cage 1 is in a suspended state, and the winding roller of the winch 18 is in a locked state, so that when the lifting arm 24 is lifted upward, the end of the traction cable 16 close to the winch 18 can be lifted upward, and then the collecting ship travels to the lifted area. At the same time, the suspension device provided on the collecting ship can support the lifted traction cable 16, and then the collecting ship moves along the length direction of the traction cable 16 to lift the breeding cages 1 one by one onto the collecting ship for collection operations.

[0082] Furthermore, the suspension device has two suspension points, which are alternately coordinated with the traction cable 16 so that when the suspension device moves to the hollow float 1, it can switch to the traction cable 16 on the other side of the hollow float 1, thereby ensuring that the breeding cages 1 can be lifted one by one in the process of continuous movement of the breeding cages 1, thereby ensuring the convenience of the collection operation.
