Description

Technical Field

[0001] This utility model relates to the field of marine ranching technology, specifically an automatic netting collection system. Background Technology

[0002] Under normal weather conditions, marine ranches raise the upper part of the net cages to the water surface. Because there is a height difference between the edge of the net cage and the water surface, the open top of the net cage is conducive to operations such as feeding.

[0003] In severe weather, to reduce the impact of waves on the extended portion of the net cages, it is necessary to close the cages to reduce their extension height above the water surface or submerge them below the surface. Net covers can prevent fish from escaping and reduce economic burden, but the following problems exist:

[0004] Question 1: Marine ranches have a large surface area and cannot be covered manually in severe weather, so power equipment is required. However, the net cages need to be submerged in water, and the power components installed on the surface of the net cages drive the covering surface. The power components also need to be submerged in water. Under the corrosion of seawater, the lifespan of the power equipment is greatly reduced, and it may even be damaged due to seawater corrosion.

[0005] Question 2: If traction is used to control the coverage area, the distance between the power unit and the cage gradually increases as the cage descends. A difference is needed between the descent speed of the cage and the descent speed of the power unit on the coverage area to extend the coverage. This results in high precision requirements for control, because if the difference is not controlled correctly, the traction length released by the power unit on the coverage area will be less than the descent distance of the cage, leading to damage to the traction rope on the coverage area. Utility Model Content

[0006] The purpose of this invention is to provide an automatic netting cover system to solve the problems mentioned in the background art.

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

[0008] An automatic netting cover collection system includes a netting frame, the netting frame being raised and lowered by a lifting traction device, and further includes:

[0009] The sealing module consists of a sealing assembly and a control rope. The control rope is divided into four parts by a directional roller group: a sealing part, a rotating part, a sealing connection part, and a rotating connection part. The sealing connection part and the rotating connection part are independently pulled by winding module A and winding module B, respectively. Two end frames are fixedly connected to the top surface of the wire mesh frame. The sealing part passes through the holes on the side of the end frame and is slidably connected to the end frame.

[0010] The sealing assembly includes a mesh cover and a slider. The slider is disposed at the sealing portion and located between two adjacent end frames. The slider includes a sliding unit, a lockable sliding unit, and a fixing unit. There are two fixing units. The fixing unit is fixedly connected to one end of the sealing portion near the rotating part. The lockable sliding unit is slidably connected to one end of the sealing portion near the sealing connection part. The lockable sliding unit is detachably connected to the end frame through a locking device. The sliding unit slides outside the sealing portion.

[0011] As a further embodiment of this utility model: the directional roller assembly includes roller A, roller B, and roller C. Roller A is located between the cover portion and the cover connecting portion, roller B is located between the rotating portion and the rotating connecting portion, and roller C is located between the cover portion and the rotating portion. The cover portion and the rotating portion are parallel.

[0012] As a further improvement of this utility model: the mesh cover is a metal mesh plate, the middle part of the mesh cover has an elastic rotating shaft, and the posture of the mesh cover changes between an "I" shape and a "V" shape.

[0013] As a further embodiment of this utility model: the mesh cover is a mesh, and the slider is fixedly connected to the side of the mesh cover.

[0014] As a further improvement of this utility model: after the mesh cover is fully opened, the mesh cover closes the open end face of the mesh cage frame.

[0015] As a further solution of this utility model: the sealing assembly and the control rope are replaced with an integrated net, which is divided into a large aperture area, a small aperture area and an open groove area according to its length, and the end frame and the auxiliary structures on the end frame are removed. The net is directly wound up by the winding module A and the winding module B.

[0016] As a further improvement of this utility model: a permanent magnet that is magnetically connected to the fixing unit is fixedly connected to the side of the end frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This technical solution changes the control method of directly driving the winding via a power component, altering the control trajectory of the cover net. First, the sealing connection is released to allowance. Then, a lifting traction device lowers the net box frame. By utilizing the change in the distance between the net box frame and the winding module, the net box frame ultimately drives the cover net to move along the controlled trajectory, achieving closure. The movement trajectory of the net box frame is coupled with that of the cover net. This coordinated movement simplifies the control method and avoids the traction breakage problem caused by insufficient control precision due to speed difference adjustments.

[0025] Please see Figures 1-4In this embodiment, the cage frame 1 is raised and lowered by a lifting traction device 13. It also includes a capping module consisting of a capping assembly 3 and a control rope 6. The control rope 6 is divided into four parts by a directional roller group 2: a capping section 61, a rotating section 62, a capping connection section 63, and a rotating connection section 64. The capping connection section 63 and the rotating connection section 64 are independently pulled by a winding module A4 and a winding module B5, respectively. Two end frames 11 are fixedly connected to the top surface of the cage frame 1. The capping section 61 passes through holes on the side of the end frame 11 and is slidably connected to the end frame 11. The directional roller group 2 includes rollers A21, B22, and C23. Roller A21 is located between the capping section 61 and the capping connection section 63; roller B22 is located between the rotating section 62 and the rotating connection section 64; and roller C23 is located between the capping section 61 and the rotating section 62. The capping section 61 and the rotating section 62 are parallel.

[0026] Please see Figure 2 The lifting traction device 13, as the power component driving the lifting and lowering of the net cage frame 1, can use traction or rack and pinion to drive the net cage frame 1 to descend below the water surface. The net cage frame 1 descends along the guide post, which is shown in the diagram. The end of the net cage frame 1 has an open structure, and the control rope 6 drives the cover assembly 3 to move and cover the net cage frame 1.

[0027] The two ends of the control rope 6 are guided to the same side by rollers B22 and C23 respectively. The capping connection part 63 and the slewing connection part 64 are connected to the winding module A4 and the winding module B5 respectively. The capping part 61 and the slewing part 62 change direction by roller A21.

[0028] An end frame 11 is provided above the cage frame 1, and the cover part 61 passes through the end frame 11, forming an area that covers the port of the cage frame 1 between two adjacent end frames 11.

[0029] Improvement results: Please refer to Figure 2 During the descent of the gabion frame 1 without the lifting traction device 13 controlling it, the winding module A4 releases the capping connection part 63, resulting in a large length allowance for the capping connection part 63. The winding module B5 does not require control. The capping assembly 3 controls the gabion descent, while the winding module B5 remains locked, preventing the slewing connection part 64 from releasing its length. The slewing connection part 64 begins to extend, and the allowance in the capping connection part 63 begins to straighten. At this stage, only the lifting traction device 13 is operational. The control rope 6 moves in the following directions: capping connection part 63, capping part 61, slewing part 62, and slewing connection part 64. The capping part 61 moves towards the roller C23. Once the capping part 61 begins to move, it naturally drives the net to close the gabion frame 1.

[0030] Furthermore, if the top of the net cage is a certain distance above the water level, fish will have difficulty escaping. If the top of the net cage is close to the water level, some jumping fish will escape. If the net cage is below the water level, most fish will escape. Therefore, this method perfectly meets the enclosure requirements of the net cage and divides control into two stages.

[0031] Phase I: The winding module A4 controls the release of the excess material from the cap connection 63. The lifting traction device 13 lowers in conjunction with the net cage frame 1. When the distance between the top open end of the net cage frame 1 and the water surface is reduced to a dangerous height, the excess material released from the cap connection 63 is fully extended, and the net cage is sealed.

[0032] Phase II: The winding module A4, winding module B5, and lifting traction device 13 control the synchronous release of the net cage frame 1 through couplings or other linkage mechanisms to complete the net cage closure and descent operation.

[0033] To further optimize the control method of the sealing assembly 3, the following improvements are made:

[0034] Improvements: The sealing assembly 3 includes a mesh cover 31 and a slider 32. The slider 32 is located at the sealing part 61 and between two adjacent end frames 11. The slider 32 includes a sliding unit 321, a lockable sliding unit 322, and a fixing unit 323. There are two fixing units 323. The fixing unit 323 is fixedly connected to the end of the sealing part 61 near the rotating part 62. The lockable sliding unit 322 is slidably connected to the end of the sealing part 61 near the sealing connection part 63. The lockable sliding unit 322 is detachably connected to the end frame 11 through a locker 12. The sliding unit 321 slides outside the sealing part 61.

[0035] Before the cover part 61 moves toward the roller C23, the locking device 12 is fixed to the lockable sliding unit 322. The fixing method can be achieved by means of pin hole, magnetic adsorption, buckle, etc., or it can be fixed in advance or remotely controlled. The fixing method is existing technology and will not be described in detail here.

[0036] When the capping part 61 moves toward the roller C23, the fixing unit 323 slides along with multiple capping parts 61 and the sliding unit 321. When the fixing unit 323 reaches the end frame 11, it is larger than the hole provided for the sliding of the capping part 61 at the end frame 11, preventing the capping part 61 from moving further. The remaining portion of the capping connecting part 63 is then stretched to the capping part 61, and the capping assembly 3 is in a flattened state. When the net cover 31 is impacted by a fish, the locking device 12 and the end frame 11 limit the capping assembly 3, ensuring that the capping assembly 3 remains flat and does not deform.

[0037] This approach can further optimize the control phase, as follows:

[0038] Phase A: The winding module A4 controls the release of the excess material from the cap connection 63. The lifting traction device 13 lowers in conjunction with the cage frame 1. When the cap 61 moves toward the roller C23, the fixing unit 323 slides along with multiple caps 61 and the sliding unit 321. When the distance between the top open end of the cage frame 1 and the water surface decreases to a dangerous height, the fixing unit 323 reaches the end frame 11. The locking device 12 and the end frame 11 limit the cap assembly 3, ensuring that the cap assembly 3 is in a flattened state and will not deform. The excess material released by the cap connection 63 is not fully utilized.

[0039] Phase B: The lifting traction device 13 controls the wire mesh frame 1 to continue descending. Only the winding module B5 needs to be controlled independently to descend. When the set depth is reached, the remaining amount of the cap connection part 63 is completely flattened.

[0040] Phase C: The rising phase. The winding module B5 and the lifting traction device 13 simultaneously wind up the wire mesh frame 1, keeping the capping assembly 3 in a flattened state. The capping connection 63 provides some slack until the frame 1 rises to the set height. The winding module B5 closes, and the winding module A4 opens. After the capping connection 63 straightens, the winding module A4 winds up, and the winding module B5 releases, completing the storage of the capping assembly 3.

[0041] To further optimize the control method at stage C, the following improvements were made:

[0042] Improvement: A permanent magnet that is magnetically connected to the fixing unit 323 is fixedly connected to the side of the end frame 11.

[0043] Phase C1: The rising phase. The lifting traction device 13 controls the cage frame 1 to rise. The capping connection part 63 and the slewing connection part 64 have excess space. The metal objects or magnets on the surface of the fixing unit 323 adhere to the magnets at the end frame 11, and the capping assembly 3 is in an adhered state. When the capping assembly 3 is wound up, it is only necessary to open the winding module A4. The winding module A4 winds up the control rope 6 to realize the storage of the capping assembly 3.

[0044] The mesh cover 31 is a metal mesh plate. The middle part of the mesh cover 31 has an elastic rotating shaft, and the posture of the mesh cover 31 can change between a straight line and a V shape.

[0045] When the mesh cover 31 is a metal mesh plate, the elastic rotating shaft in the middle of the mesh cover 31 can control the mesh cover 31 to unfold into a flat plane without being subjected to external force. In the folded state, it is V-shaped; in the unfolded state, it is straight. A torsion spring can be installed inside the rotating shaft, or spring sheets can be installed between the mesh covers 31. This method can be used in conjunction with stage C1 to achieve both elastic and magnetic attraction.

[0046] The mesh cover 31 is a mesh, and the slider 32 is fixedly connected to the side of the mesh cover 31. When the mesh cover 31 is a mesh, the slider 32 retracts, and the mesh cover 31 will naturally droop.

[0047] After the mesh cover 31 is fully opened, it closes the open end face of the wire mesh frame 1. This method ensures that the surface of the wire mesh frame 1 is completely closed.

[0048] Replace the capping assembly 3 and control rope 6 with an integrated net, and remove the end frame 11 and its auxiliary structures. The net is then directly wound up using the winding module A4 and winding module B5.

[0049] Further optimization involves replacing the capping assembly 3 and control rope 6 with a net. The net is divided into structures such as large aperture, small aperture, and open slot. During control, the net frame 1 can be closed by coordinating the winding module A4 and winding module B5 to change the type of net at the capping part 61 and the rotating part 62.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present technical solution.
