Description

Technical Field

[0001] This utility model relates to the field of marine aquaculture technology, and more specifically, to a self-cleaning netting for marine aquaculture cages. Background Technology

[0002] Netting is the mesh structure that makes up the main body of aquaculture cages. Its main function is to enclose the aquaculture area and prevent fish from escaping, while allowing water to flow freely to ensure water exchange and dissolved oxygen supply. It is widely used in the large-scale aquaculture of marine fish, shellfish and other aquatic products.

[0003] However, the mesh structure is not strong enough and is prone to displacement and deformation due to water flow impact or long-term use, affecting the enclosure effect. Furthermore, the mesh is prone to the adhesion of impurities such as algae and shellfish over a long period of use, which can cause the mesh to become clogged and affect water exchange and dissolved oxygen supply.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To address the problems in related technologies, this utility model proposes a self-cleaning net for marine aquaculture cages, which solves the problems of insufficient strength of existing net structures, easy displacement and deformation due to water flow impact or long-term use, affecting the enclosure effect, and the easy adhesion of algae, shellfish and other impurities to the net after long-term use, leading to mesh blockage and affecting water exchange and dissolved oxygen supply.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows: A self-cleaning net for marine aquaculture cages includes multiple nets, each net having an installation component. The installation component includes reinforcing plates connecting the multiple nets, an installation frame connecting the reinforcing plates to the nets, one end of the installation frame being snapped into an aquaculture cage frame, and a cleaning component being installed on the aquaculture cage frame.

[0007] Furthermore, in order to better clean the netting of the marine aquaculture cages, the cleaning components include an auxiliary groove on the cage frame, an auxiliary frame installed inside the auxiliary groove, a motor mounted on the auxiliary frame, a gear one installed at one end of the motor, a gear two meshing with the teeth of the gear one, the gear two installed on the outer periphery of the cage frame, a cleaning plate connected to one end of the gear one via a bearing, one side of the cleaning plate contacting the netting and one side of the reinforcing plate, and a sliding groove on the cage frame, the interior of which is connected to the cleaning plate.

[0008] Furthermore, in order to better fit the netting of marine aquaculture cages, the cleaning plate is provided with an adjustment groove, and the inside of the adjustment groove is equipped with multiple elastic plungers, one end of which is equipped with a cleaning brush.

[0009] Furthermore, a scraper is provided on one side of the reinforcing plate to better assist the cleaning brush in cleaning.

[0010] Furthermore, in order to better secure the installation frame and improve the stability of the marine aquaculture cage netting, multiple fixing screws are threaded onto the aquaculture cage frame, with one end of each screw connected to the installation frame.

[0011] Furthermore, in order to better connect multiple aquaculture cages, multiple connection holes are provided on the aquaculture cage frame, and connecting ropes are connected inside the connection holes.

[0012] The beneficial effects of this utility model are as follows: (1) By installing the installation components on the net, the structural strength of the net is improved, the impact force of the water flow is dispersed, displacement and deformation are prevented, and the enclosure effect is maintained. The overall tensile strength and torsional resistance of the net are greatly enhanced, effectively resisting the impact and disturbance of the water flow. The cleaning components installed on the installation components can effectively remove impurities such as algae and shellfish, avoid clogging of the mesh, ensure water exchange and dissolved oxygen supply, ensure smooth exchange of water inside and outside the aquaculture net cage, and continuously provide sufficient dissolved oxygen for the aquaculture organisms.

[0013] (2) The cleaning brush, which is equipped with an adjustment groove and elastic plunger on the cleaning plate, can be adaptively adjusted according to the mesh density, surface unevenness and thickness of the attached material, ensuring that the bristles are always in close contact with the mesh surface and removing the attached impurities without damaging the mesh. The scraper on the reinforcing plate can perform a second strong scraping on the cleaning brush, effectively preventing loose impurities from re-attaching or accumulating in the cleaning area, avoiding secondary pollution, and significantly improving the thoroughness and continuity of cleaning.

[0020] Example 2:

[0021] like Figure 1 , Figure 4 , Figure 5As shown, a self-cleaning net for marine aquaculture cages according to an embodiment of the present invention includes a cleaning component 3 on the aquaculture cage frame 203. The cleaning component 3 includes an auxiliary groove on the aquaculture cage frame 203, an auxiliary frame 301 installed inside the auxiliary groove, a motor 302 on the auxiliary frame 301, a gear 303 installed at one end of the motor 302, a gear 304 meshing with the teeth of the gear 303, the gear 304 being installed on the periphery of the aquaculture cage frame 203, and a cleaning plate 305 connected to one end of the gear 303 via a bearing. One side of the cleaning plate 305 contacts the net 1 and the reinforcing plate 201. The aquaculture net cage frame 203 has a sliding groove, and the interior of the sliding groove is connected to the cleaning plate 305. The cleaning plate 305 has an adjustment groove, and the interior of the adjustment groove is equipped with four elastic plungers 4, which are used to adaptively adjust the cleaning brush 5 according to the condition of the net 1. One end of the elastic plunger 4 is equipped with a cleaning brush 5, which is used to clean the impurities attached to the net 1. One side of the reinforcing plate 201 is equipped with a scraper 6, which is used to assist in cleaning the impurities assisted by the cleaning brush 5, avoid secondary pollution, and improve continuous cleaning efficiency. The cleaning part of the scraper 6 has a serrated structure. The scraper 6 is a detachable structure and is made of metal or plastic. The scraper 6, cleaning brush 5, elastic plunger 4, cleaning plate 305, gear 2 304, gear 1 303, fixing screw 7, aquaculture net cage frame 203, mounting frame 202, and reinforcing plate 201 are equipped with corrosion-resistant coating and anti-oxidation coating (not shown in the figure) in actual use. In actual use, motor 302 is electrically connected to a controller (not shown in the figure). The controller is a PLC (Programmable Logic Controller) or a microcontroller. The specific working control program of the controller is written and set according to the actual situation, which is conducive to the precise control of the electrically connected electrical components. In actual use, the above structure is electrically connected to an external power supply or a battery (not shown in the figure). Motor 302, elastic plunger 4, cleaning brush 5, gear 2 304, gear 1 303, and fixing screw 7 are existing technologies and will not be described in detail. The specific model and specifications need to be selected and determined according to the actual specifications of the device.

[0022] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0023] In summary, with the help of the above-mentioned technical solution of this utility model, when algae, shellfish and other marine attachments gradually attach to the netting 1 of the marine aquaculture cage due to seawater flow during use, in order to maintain the water permeability and structural strength of the netting 1, the self-cleaning function is activated. First, the controller connects the power supply of the motor 302, the motor 302 starts to run, and the output end of the motor 302 drives the gear 1 303 to rotate. The gear 1 303 meshes with the gear 2 304. The gear 2 304 is fixed to the periphery of the aquaculture cage frame 203. Therefore, when the gear 1 303 rotates, a transmission linkage is formed through the gear meshing action, so that the gear 1 303 moves circumferentially around the periphery of the gear 2 304. As gear 303 moves, the cleaning plate 305 connected to gear 303 via bearings moves synchronously. The cleaning plate 305 is embedded in the sliding groove of the aquaculture net frame 203, ensuring its movement trajectory is stable and it slides circumferentially along the surface of the net 1. The elastic plunger 4 set in the adjustment groove on the cleaning plate 305 allows the cleaning brush 5 to stick to the surface of the net 1 during the movement of the cleaning plate 305. The elastic plunger 4 adapts to the mesh density and surface unevenness of the net 1 by utilizing its expansion and contraction properties, thereby achieving uniform brushing of different areas and effectively removing attached impurities. The reinforcing plate 201 has a scraper 6 on one side. The scraper 6 has a serrated structure and is close to the area cleaned by the cleaning brush 5. When the cleaning brush 5 loosens the attached material and pushes it to one side, the scraper 6 scrapes off the remaining impurities a second time to prevent the loose material from re-attaching and improve the thoroughness of cleaning. The scraper 6 adopts a detachable design, which is convenient for replacement or cleaning of accumulated materials and ensures long-term operating efficiency. During the overall cleaning process, multiple nets 1 are connected to the reinforcing plate 201 via the mounting frame 202. The structural stability is secured to the aquaculture cage frame 203 by fixing screws 7, ensuring that the nets 1 will not shift or deform when the water flow disturbs or the cleaning component 3 is running. In addition, the connecting holes on the aquaculture cage frame 203 are equipped with connecting ropes 8, which can connect multiple aquaculture cages to each other to form an array-type aquaculture system. Under unified control, multiple cages can be cleaned synchronously or at different times, improving operation and maintenance efficiency.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
