Description

Technical Field

[0001] This utility model relates to the field of deep-sea aquaculture technology, and in particular to an interception net for deep-sea cages. Background Technology

[0002] Deep-sea cages are large-scale aquaculture facilities set up in open coastal waters at depths of 15 meters or more. They have significant advantages such as strong resistance to wind and waves, large aquaculture capacity, fast fish growth, and good product quality. In the process of deep-sea cage fish farming, feed is intercepted by placing feed-blocking nets inside the cages to prevent feed leakage and waste.

[0003] In deep-sea cage aquaculture, the feed used is mostly extruded feed, which needs to be intercepted by intercepting nets. For example, Chinese Patent Publication No. CN204534745U discloses a deep-sea cage feed interception device that resists wind, waves, and ocean currents. This device consists of an upper rod, a lower rod, and a connecting rod that 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 wind, waves, and ocean currents from all directions, thus playing a role in resisting wind, waves, and ocean currents while intercepting feed.

[0004] In practice, the interception net is fixed to the outside of the frame. However, considering that the interception net is soaked in seawater for a long time, its surface is prone to adhering to impurities such as seaweed and shellfish. When the interception net is rolled up or disassembled, the impurities on the surface of the interception net cannot be cleaned, which will affect the next use. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies that cannot clean impurities from the surface of the interception net, and to propose an interception net for deep-sea cages.

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

[0007] Design a deep-sea cage interception net, including a frame and an interception net. A winding drum is fixedly connected inside the frame. A winding rod is rotatably connected inside the winding drum. The winding rod works with the winding drum to wind up the interception net.

[0008] One end of the interception net is fixedly connected to the winding rod, and the other end is detachably connected to the winding drum through a fixing structure. The interception net is wrapped around the frame through the fixing structure.

[0009] Furthermore, the frame consists of two support frames and at least one set of support rods. The support frames are in the form of a ring structure, and the support rods are fixed circumferentially between the two support frames.

[0010] The interception net is fixedly connected to the edge with a reinforcing strip, and the interception net is erected in an S-shape on the outer wall of the support rod. The reinforcing strip slides against the support frame.

[0011] Furthermore, the outer wall of the winding drum is symmetrically provided with a tapered portion and a connecting portion on both sides. The tapered portion connects to the internal cavity of the winding drum, and both the tapered portion and the connecting portion connect to the upper and lower ends to form a relief groove. The reinforcing strip is slidably connected in the relief groove.

[0012] Furthermore, the conical portion is truncated cone-shaped on the side away from the winding drum, and the conical portion is used to scrape and clean the floating objects attached to the surface of the interception net through the truncated cone portion.

[0013] Furthermore, the fixing structure includes an elastic body, and at least one of the elastic bodies is provided on the side of the reinforcing strip on the free end side of the interception net, and the upper and lower sides of the other end of the elastic part extend outward at an angle to form an elastic part.

[0014] Furthermore, the side wall of the take-up drum connects to the internal cavity to form an opening groove, and its side wall also connects to the internal cavity to form a locking hole corresponding to the elastic body. The elastic parts on both sides pass through the locking hole by abutting deformation and abut against the inner wall of the take-up drum.

[0015] The present invention provides an interception net for deep-sea cages, which has the following advantages: The present invention, through the arrangement of a winding drum, winding rod, and elastic body, enables the interception net to be tensioned and wound up. On the one hand, after the interception net is unwound, it can be easily and quickly wrapped around the frame by engaging with the winding drum through the elastic body, thereby intercepting the foamed feed floating on the sea surface. On the other hand, after unlocking the elastic body, the winding drum and winding rod can wind up the interception net. Furthermore, during the winding process, the conical part can clean impurities adhering to the surface of the interception net, preventing it from affecting the next use. The structure is simple, the operation is convenient, and the practicality is strong. Attached Figure Description

[0022] 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.

[0023] Reference Figure 1-5 A deep-sea cage interception net includes a frame 1 and an interception net 2. A winding drum 3 is fixedly connected inside the frame 1. A winding rod 4 is rotatably connected inside the winding drum 3. The winding rod 4 works with the winding drum 3 to wind up the interception net 2.

[0024] One end of the intercepting net 2 is fixedly connected to the winding rod 4, and the other end is detachably connected to the winding drum 3 through the fixing structure 5. The intercepting net 2 is wrapped around the frame 1 through the fixing structure 5.

[0025] In some embodiments, after the interception net 2 is fixed to the periphery of the frame 1, the frame 1 is fixed inside the net cage, and the upper rod of the frame 1 is kept higher than the water surface inside the net cage and the lower rod is lower than the water surface inside the net cage. Then the feed can be put into the material blocking device. The feed is mostly extruded feed, which floats on the sea surface and is blocked by the material blocking net.

[0026] Specifically, the frame 1 and the upper pole of the cage can be fixed together to ensure the stability of the material blocking device and further improve the wind and wave resistance of the material blocking device.

[0027] Furthermore, the frame 1 consists of two support frames 11 and at least one set of support rods 12. The support frames 11 are in the form of a ring structure, and the support rods 12 are fixed circumferentially between the two support frames 11.

[0028] The edge of the interception net 2 is fixedly connected with a reinforcing strip 21. The interception net 2 is laid out in an S-shape on the outer wall of the support rod 12. The reinforcing strip 21 slides against the support frame 11.

[0029] Furthermore, the outer wall of the take-up drum 3 is symmetrically provided with a tapered portion 31 and a connecting portion 32 on both sides. The tapered portion 31 is connected to the internal cavity of the take-up drum 3, and both the tapered portion 31 and the connecting portion 32 are connected to the upper and lower ends to form a relief groove 33. The reinforcing strip 21 is slidably connected in the relief groove 33.

[0030] In this embodiment, the reinforcing strip 21 is wrapped around the outer edge of the interception net 2. On the one hand, it is used to improve the service life of the interception net 2. On the other hand, by the reinforcing strip 21 sliding against the support frame 11, it prevents the feed from leaking out along the gaps.

[0031] Specifically, the reinforcing strip 21 is preferably made of materials with deformation capabilities such as rubber and silicone, which further improves the sealing between the reinforcing strip 21 and the support frame 11;

[0032] Furthermore, relief grooves 33 are provided at the upper and lower ends of the winding drum 3, and the reinforcing strip 21 is engaged in the relief grooves 33 to prevent feed from leaking out along the gaps. In addition, the winding rod 4 is rotatably connected to the support frame 11 and the winding drum 3, and a drive handle is fixedly connected to the top of the winding rod 4.

[0033] Furthermore, the free ends of the interception net 2 are arranged in an S-shape on the outer wall of the support rod 12, so that when the interception net 2 is impacted by waves, it can contact the support rod 12 from any side, thereby improving the stability of the interception net 2 after it is tensioned.

[0034] More specifically, the conical part 31 is truncated cone-shaped on the side away from the winding drum 3, and the conical part 31 is used to scrape and clean the floating objects attached to the surface of the interception net 2 through the truncated cone portion.

[0035] In specific operations, such as Figure 3 As shown, during the winding process of the interception net 2, the conical part 31 scrapes and cleans the aquatic plants and shellfish attached to the surface of the interception net 2 through the inclined part of the cone.

[0036] In general, the fixing structure 5 includes an elastic body 51. At least one elastic body 51 is provided on the side of the reinforcing strip 21 on the free end side of the intercepting net 2. The upper and lower sides of the other end of the elastic body 51 extend outward to form an elastic part 52.

[0037] Finally, the side wall of the take-up drum 3 connects to the internal cavity to form an opening groove, and its side wall also connects to the internal cavity to form a locking hole 53 corresponding to the elastic body 51. The elastic parts 52 on both sides pass through the locking hole 53 by abutting deformation and abut against the inner wall of the take-up drum 3.

[0038] In this embodiment, the elastic body 51 is preferably made of a material with deformation capability such as rubber or plastic. The elastic body 51 and the elastic parts 52 on both sides form a triangular structure. The elastic parts 52 on both sides abut against and slide with the card hole 53 through the guide slope on the side. After the elastic part 52 recovers its deformation through the card hole 53, its unfolded end abuts against the inner wall of the winding drum 3, thereby achieving the function of tensioning the interception net 2.

[0039] In specific operation, when the interception net 2 needs to be rolled up, the elastic parts 52 on both sides are pinched simultaneously through the opening groove to make them retract, so that the elastic body 51 can be disengaged from the card hole 53.

[0040] Working method: During operation, one end of the interception net 2 is slidably connected to the tapered part 31 and fixedly connected to the outer wall of the winding rod 4. The other end of the interception net 2 is laid on the outer wall of the support rod 12 in an S-shape. The elastic body 51 at the other end of the interception net 2 is also engaged in the card hole 53 to achieve the function of tensioning the interception net 2 around the frame 1.

[0041] Then, when it is necessary to roll up the interception net 2, the elastic parts 52 on both sides are pinched simultaneously through the opening slot to make them retract, so that the elastic body 51 can be disengaged from the card hole 53. Then, the winding rod 4 is driven to rotate by the drive handle, and the winding rod 4 rolls up the interception net 2. During the winding process, the conical part 31 will also clean the impurities attached to the surface of the interception net 2 through the inclined part of the cone.

[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.
