Description

Technical Field

[0001] This utility model relates to the field of deep-sea aquaculture technology, and in particular to a wave-resistant feed barrier. Background Technology

[0002] Aquaculture cages are facilities used for aquaculture. Their design and functional features meet the needs of large-scale and efficient aquaculture. They are facilities enclosed by a net structure and used to raise aquatic products such as fish and shellfish in water.

[0003] After the feed-blocking net is placed inside the net cage, with its upper rod above the water surface and its lower rod below the water surface, seafood can be raised by feeding. For example, Chinese Patent Publication No. "CN204634746U" discloses a deep-sea net cage anti-wave and anti-current feed-blocking device. In this device, the upper rod, lower rod, and connecting rod are interconnected to form the skeleton of the entire device, stabilizing its structure. The netting is spirally interwoven between the connecting rods, effectively resisting the impact of waves and currents from all directions, thus providing protection against waves and currents and intercepting feed.

[0004] In practice, the material barrier net is fixed to the upper part of the net cage with hooks to achieve a fixing function. However, considering that the entire material barrier net covers the top opening of the net cage, the top opening of the net cage is blocked, which makes it inconvenient to harvest seafood or observe the breeding situation, and its practicality is poor. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of harvesting seafood or observing its aquaculture, by proposing a wind and wave resistant material barrier net.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a wave-resistant material barrier net, including a net box and a material barrier net placed inside the net box. The top half of the material barrier net floats on the sea surface, and at least one set of tension components is provided between the top half of the material barrier net and the top of the net box, the tension components being used to fix the material barrier net.

[0008] The tensioning assembly includes a ratchet and a pawl, the pawl being used to lock the ratchet and the pawl being unlocked and separated from the ratchet by an elastic structure.

[0009] Furthermore, the tensioning assembly also includes a bracket, with rotating shafts rotatably connected to both ends of the bracket. A pair of rotating shafts rotate synchronously through a transmission component. One end of the rotating shaft passes through the bracket and is fixedly connected to the ratchet, while the other end of the rotating shaft is fixedly connected to a winding wheel, which is used to unwind the tension rope.

[0010] Furthermore, it also includes hooks, with the hooks fixedly connected to the free end of the pull rope and one end of the bracket, and the two hooks respectively hanging on the top of the cage and the barrier net.

[0011] Furthermore, the pawl is rotatably connected to the side of the bracket via a pivot and a torsion spring, and the ratchet engages with the pawl along the direction of rope extension to fix the winding wheel.

[0012] Furthermore, a protective cover is fixedly connected to the side of the bracket, and an unlocking rod is rotatably connected to it. One end of the unlocking rod has a protruding structure, and the other end passes through the protective cover. The end of the pawl away from the pivot axis slides against the protruding structure through a guide slope.

[0013] Furthermore, the elastic structure includes a positioning part and an elastic part, both of which are annular structures. The positioning part is fixedly connected to the side of the protective cover and sleeved around the unlocking rod. The elastic part is fixedly connected to the outside of the unlocking rod and rotatably connected to the central through hole of the positioning part.

[0014] Furthermore, the positioning part is provided with a pair of positioning grooves in the central through hole, the elastic part extends through both sides to form deformation grooves, and its outer wall is provided with protrusions corresponding to the deformation grooves. The protrusions are locked in the positioning grooves by abutting deformation.

[0015] The present invention provides a wave-resistant material-blocking net with the following advantages: The net is installed inside a net cage, floating on the sea surface. It is fixed to the top of the net cage by at least one set of opposing tension components. When the tension components unwind the ropes, the net can be moved to the edge of the net cage by pulling, facilitating the cleaning and replacement of feed inside. Furthermore, tightening the ropes secures the net, preventing it from floating aimlessly in the wind and waves, thus avoiding feed scattering and waste. Additionally, fixing the net near the center of the net cage prevents it from obstructing the top opening, facilitating observation of seafood growth and harvesting. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-6 A wave-resistant barrier net includes a net box 1 and a barrier net 2 placed inside the net box 1. The top half of the barrier net 2 floats on the sea surface, and at least one set of tension components 3 are provided between the top half of the barrier net 2 and the top of the net box 1. The tension components 3 are used to fix the barrier net 2.

[0025] The tensioning assembly 3 includes a ratchet 31 and a pawl 32. The pawl 32 is used to lock the ratchet 31, and the pawl 32 is unlocked and separated from the ratchet 31 by the elastic structure 4.

[0026] In some embodiments, the material barrier net 2 includes a frame, with the material barrier net fixedly connected to the periphery and bottom of the frame. Specifically, the frame keeps its upper rod above the water surface inside the net cage and its lower rod below the water surface inside the net cage to feed the seafood.

[0027] Furthermore, the tensioning assembly 3 also includes a bracket 33, with rotating shafts rotatably connected to both ends of the bracket 33. A pair of rotating shafts rotate synchronously through a transmission component 34. One end of the rotating shaft passes through the bracket 33 and is fixedly connected to the ratchet 31, while the other end of the rotating shaft is fixedly connected to a winding wheel 35, which is used to unwind the tensioning rope.

[0028] Furthermore, it also includes hooks 36, with the hooks 36 fixedly connected to the free end of the pull rope and one end of the bracket 33, and the two hooks 36 respectively hanging on the top of the net box 1 and the barrier net 2.

[0029] In this embodiment, the pair of transmission components 34 are a pair of transmission gears with different diameters. The large transmission gear is fixedly connected to the winding wheel 35 on the same rotating shaft, and the other small transmission gear and the fixed handle are fixedly connected to another rotating shaft. By driving the large transmission gear to rotate through the small transmission ratio gear, the rotation speed is reduced and the torque is increased, so that the fixed handle can be used to drive the winding wheel 35 to rotate and wind up the rope.

[0030] Furthermore, the hook 36 is preferably a self-locking hook with a spring locking plate. Several pairs of limiting plates are provided on the top of both the wire mesh box 1 and the material barrier net 2. The two hooks 36 are hung between a pair of limiting plates to prevent slippage caused by wind, waves and the material barrier net 2.

[0031] Specifically, when the pull rope is stretched freely, the material barrier net 2 can be moved to the edge of the net box 1 by pulling, so as to facilitate the cleaning and replacement of the feed inside the net. On the other hand, after the pull rope is tightened, the material barrier net 2 is fixed to prevent it from floating randomly due to the influence of wind and waves, which would cause the feed to be washed away and wasted.

[0032] More specifically, the pawl 32 is rotatably connected to the side of the bracket 33 via a pivot and a torsion spring 37, and the ratchet 31 engages with the pawl 32 along the direction of the rope extension to fix the winding wheel 35.

[0033] Specifically, the pawl 32 is engaged with the ratchet 31 under the action of the torsion spring 37, which prevents the winding wheel 35 from rotating and prevents the pull rope from stretching and causing the material barrier net 2 to sway. The two ends of the torsion spring 37 are fixedly connected to the pawl 32 and the bracket 33, respectively.

[0034] In general, a protective cover 38 is fixedly connected to the side of the bracket 33, and an unlocking rod 39 is rotatably connected. One end of the unlocking rod 39 is provided with a protruding structure 391, and the other end passes through the protective cover 38. The pawl 32, away from the pivot, slides against the protruding structure 391 through a guide slope.

[0035] Furthermore, the elastic structure 4 includes a positioning part 41 and an elastic part 42. Both the positioning part 41 and the elastic part 42 are annular structures. The positioning part 41 is fixedly connected to the side of the protective cover 38 and sleeved around the unlocking rod 39. The elastic part 42 is fixedly connected to the outside of the unlocking rod 39 and rotatably connected to the central through hole of the positioning part 41.

[0036] Finally, the positioning part 41 is provided with a pair of positioning grooves 411 in the central through hole, the elastic part 42 passes through both sides to form deformation grooves 421, and its outer wall is provided with protrusions 422 corresponding to the deformation grooves 421. The protrusions 422 are locked in the positioning grooves 411 by abutting deformation.

[0037] In this embodiment, a handwheel is fixedly connected to the free end of the unlocking lever 39. The handwheel drives the unlocking lever 39 to rotate the protruding structure 391 half a revolution. During the rotation of the protruding structure 391, it slides against the guide slope of the pawl 32. Then the pawl 32 is driven to rotate and can disengage from the ratchet 31. At this time, the pull rope can be freely stretched.

[0038] Specifically, the elastic part 42 is preferably made of a material with deformation capability such as rubber or plastic. The unlocking rod 39 rotates synchronously with the elastic part 42. During the rotation of the elastic part 42, the protrusion 422 is concave to a certain extent through the deformation groove 421, thereby avoiding the positioning part 41. After the protrusion 422 recovers its deformation and is locked in the positioning groove 411, the unlocking rod 39 can be fixed.

[0039] It is worth mentioning that, such as Figure 6 As shown, if the protrusion 422 is in the left positioning groove 411, the protrusion structure 391 does not abut against the pawl 32. If the protrusion 422 is in the right positioning groove 411, the protrusion structure 391 abuts against the pawl 32 and drives the pawl 32 to separate from the ratchet 31.

[0040] Working method: During operation, the unlocking lever 39 is rotated by handwheel. The unlocking lever 39 is connected to the elastic part 42 and rotates synchronously. When the protrusion 422 is locked in the right positioning groove 411, the protrusion structure 391 abuts against the pawl 32 and drives the pawl 32 to separate from the ratchet 31. At this time, the material blocking net 2 can be pulled to move towards the side of the net box 1 to facilitate the cleaning and replacement of feed.

[0041] Then, the pull rope is wound up by the winding wheel 35. When the barrier net 2 is placed near the center of the net box 1, the unlocking rod 39 is reset, the protrusion 422 is locked with the left positioning groove 411, and the pawl 32 is locked with the ratchet 31 under the action of the torsion spring 37. At this time, the pull rope cannot be stretched to prevent the barrier net 2 from swaying.

[0042] 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 utility model.
